[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, it should not be construed that the embodiments of this disclosure are limited to those described herein. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0041] During the assembly of wind turbine generator sets, construction platforms are typically used to improve the safety of the assembly site. For example, but not limited to, in this embodiment, the construction platform can be used in the assembly of auxiliary towers, such as in the assembly of auxiliary precast concrete towers.

[0042] Current construction platforms can typically only accommodate towers of a single size. This means that multiple construction platforms of different sizes may need to be configured during the assembly of large towers, increasing the cost of tower assembly.

[0043] Referring to Figure 1, an embodiment of this disclosure provides a construction platform suitable for wind turbine generator sets. The construction platform includes a support platform 1, which may have a support surface to facilitate the support of operators or materials during the construction process.

[0044] The size of the support platform 1 provided in the embodiments of this disclosure is adjustable, for example, but not limited to, the support platform 1 is a scalable platform, but not limited thereto.

[0045] In this embodiment, the support platform 1 may include a central platform and an outer platform connected to the outer periphery of the central platform. The outer platform is detachably connected to the central platform so that the size of the support platform 1 is adjustable. For example, but not limited to, when adapting to a small-diameter tower, the outer diameter of the central platform matches the tower diameter, and the support platform 1 can use only the central platform. When adapting to a large-diameter tower, in order to avoid an excessive distance between the outer periphery of the support platform 1 and the inner wall of the tower, which may pose a safety hazard, the outer platform can be connected to the central platform to increase the size of the support platform 1.

[0046] The support platform 1 provided in the embodiments of this disclosure is adjustable in size, and the size of the support platform 1 can be selected according to the space requirements of the working conditions, so that the support platform 1 can adapt to different working conditions, thereby improving the versatility of the support platform 1.

[0047] The embodiments disclosed herein are illustrated using a support platform 1 having a generally circular support surface as an example. The radius of the support surface is adjustable, thereby making the area of ​​the support surface adjustable, but this is not a limitation.

[0048] The construction platform according to some embodiments of the present disclosure also includes a guardrail assembly 2, which can be disposed on the outer periphery of the support platform 1 to protect the operators or materials on the support surface and prevent the operators or materials from accidentally moving outside the support surface, thereby improving the reliability of the construction platform.

[0049] According to the embodiments of this disclosure, the length of the guardrail assembly 2 along the circumference of the support platform 1 is adjustable, making it possible for the same guardrail assembly 2 to adapt to support platforms 1 of different sizes. When the same guardrail assembly 2 is applied to support platforms 1 of different sizes, the assembly cost of the wind turbine generator is reduced.

[0050] Referring to Figures 1 and 2, the guardrail assembly 2 of this embodiment includes a plurality of first support members 21 and a plurality of second support members 22. The first support members 21 extend vertically, and the plurality of first support members 21 are connected to the support platform 1 at intervals along the circumference of the support platform 1. The second support members 22 can be connected between two adjacent first support members 21. The first support members 21 are used to provide support for the second support members 22, so that the second support members 22 can be reliably connected to the support platform 1 and can effectively stop and intercept materials.

[0051] To better accommodate support platforms 1 of different sizes, at least one of the multiple second support members 22 is configured to have an adjustable length along the circumference of the support platform 1. Compared to flexible structures such as ropes or chains, the second support member can withstand larger external loads, is less prone to swaying or swinging, and is less prone to significant deformation, thus providing reliable interception and protection for operators or objects on the support platform 1.

[0052] In order to accommodate the size adjustment of the support platform 1, at least one of the multiple second support members 22 has an adjustable length. For ease of description, this embodiment takes the example of multiple second support members 22 having adjustable lengths, but it is not limited to this.

[0053] Referring again to Figure 2, the second support member 22 includes a first crossbar unit 221 and a second crossbar unit 222, and both the first crossbar unit 221 and the second crossbar unit 222 are rigid components. The first crossbar unit 221 and the second crossbar unit 222 are movably connected, so that the second support member 22 is formed as a telescopic rod assembly with an adjustable circumferential length along the support platform 1.

[0054] According to the embodiments of this disclosure, the first crossbar unit 221 and the second crossbar unit 222 are movably connected, and the first crossbar unit 221 and the second crossbar unit 222 are respectively hinged to the first support member 21, so that the first support member 21 can flexibly extend and retract, avoid movement jamming, and thus improve the reliability of the second support member 22.

[0055] During the length adjustment of the second support member 22, the angle between the second support member 22 and the first support member 21 will change. In order to avoid stress at the connection between the end of the second support member 22 and the first support member 21, the two ends of the second support member 22 can be rotatably connected to the first support member 21 respectively, so as to adapt to the change of the angle.

[0056] Referring to Figure 2, the first end of the first crossbar unit 221 and the first end of the second crossbar unit 222 are rotatably connected to two adjacent first support members 21, and the second end of the first crossbar unit 221 and the second end of the second crossbar unit 222 are movably connected, so that the length of the second support member 22 is adjustable.

[0057] In some embodiments, the first crossbar unit 221 includes a first crossbar, and a first connecting portion is provided at the second end of the first crossbar. The second crossbar unit 222 includes a second crossbar, and a second connecting portion is provided at the second end of the second crossbar. One of the first connecting portion and the second connecting portion is a hollow tube portion, and the other is inserted into the hollow tube portion, so that the first connecting portion and the second connecting portion can be movably connected.

[0058] In some embodiments, the first connecting portion of the first crossbar and the second connecting portion of the second crossbar are movably inserted to adjust the length of the overlapping portion of the first connecting portion and the second connecting portion. When the hollow tube portion is provided on the first crossbar unit 221, the second connecting portion of the second crossbar unit 222 can be inserted into the hollow tube portion. By adjusting the length of the second connecting portion inserted into the hollow tube portion, the overall length of the second support member can be adjusted.

[0059] In some embodiments, the first crossbar and the second crossbar are arranged parallel to the support surface of the support platform 1, but this is not a limitation.

[0060] As an example, a connecting seat 213 is provided on the first support member 21. For example, but not limited to, the connecting seat 213 can be fixed to the first support member 21 by welding or fastener connection. The connecting seat 213 is provided with a first pin connection hole, and the first end of the first crossbar unit 221 can be provided with a second pin connection hole. The first crossbar unit 221 is connected to the connecting seat 213 through the first pin connection hole, and then connected to the first support member 21, but is not limited thereto. In this embodiment, the connecting seat 213 is fixed to the first support member 21, and the first crossbar unit 221 and the connecting seat 213 are hinged together, thereby making the first crossbar unit 221 hinged to the first support member 21.

[0061] According to an embodiment of this disclosure, the first crossbar unit 221 is rotatably connected to the connecting seat 213 through the first pin connection hole, thereby realizing the rotatable connection between the first crossbar unit 221 and the first support member 21.

[0062] To improve the assembly efficiency of the first support member 21 and the horizontal railing, one of the first pin connection hole and the second pin connection hole can be set as an oblong hole to facilitate docking and assembly and improve assembly efficiency, but this is not a limitation.

[0063] Furthermore, the connection between the connecting seat 213 and the first crossbar unit 221 via a rotating shaft or by means of bolts is within the scope of protection of this disclosure.

[0064] For ease of description, this embodiment takes the connection between the connecting seat 213 and the first crossbar unit 221 via bolts as an example. In this embodiment, the bolt is used as a rotating shaft, and the first crossbar unit 221 is rotatably connected to the bolt, that is, the first crossbar unit 221 is hinged to the connecting seat 213 of the first support member 21 via the bolt.

[0065] In the above embodiment, the example is taken as follows: the connecting seat 213 is fixedly connected to the first support member 21, and the first crossbar unit 221 is rotatably connected to the connecting seat 213 through a rotating shaft, thereby realizing that the first crossbar unit 221 is rotatably connected to the first support member 21. However, this is not a limitation.

[0066] In addition, as needed, the connecting seat 213 can be rotatably connected to the first support member 21. In order to prevent the connecting seat 213 from sliding along the extension direction of the first support member 21, a limiting part is also provided on the first support member 21, such as, but not limited to, a limiting protrusion. The limiting protrusion can be provided below the connecting seat 213, and the connecting seat 213 is limited by the limiting protrusion.

[0067] Referring to Figure 2, in this embodiment, in order to improve the structural strength of the second support member 22, both the first and second crossbars can be set as solid bars, and a hollow tube part is provided at the second end of the first crossbar, which can be used to accommodate the second connecting part of the second crossbar, but is not limited thereto. In order to reduce the weight of the guardrail assembly 2, both the first and second crossbars can be set as hollow tubes, but is not limited thereto.

[0068] In this embodiment, the interior of the hollow tube can be a light hole, and the second connecting part of the second crossbar can be inserted into the hollow tube. In order to improve the reliability of the second support member 22, the length of the second connecting part of the second crossbar inserted into the hollow tube is not less than 10cm, thereby effectively preventing the second connecting part of the second crossbar from accidentally coming out of the hollow tube.

[0069] To improve the accuracy of the relative movement of the first and second crossbars, a first guide portion is provided inside the hollow tube, and a second guide portion matching the first guide portion is provided at the second connecting portion of the second crossbar. One of the first and second guide portions is a guide groove extending along the extension direction of the first crossbar, and the other is a slider, but not limited to this. By allowing the slider to slide within the guide groove, the reliability of the relative movement of the first and second crossbars is improved.

[0070] The above embodiment is illustrated by taking the second support member 22, which includes a first crossbar unit 221 and a second crossbar unit 222 that are nested together, as an example, but is not limited thereto.

[0071] In order to improve the efficiency of length adjustment of the second support member 22 in this embodiment, the second support member 22 also includes a connector. The two opposite ends of the connector have a first connecting part and a second connecting part, respectively. One of the first connecting part and the first connecting part is a first hollow tube, and the other is inserted into the first hollow tube, so that the first connecting part and the first connecting part can be movably inserted. One of the second connecting part and the second connecting part is a second hollow tube, and the other is inserted into the second hollow tube, so that the second connecting part and the second connecting part can be movably inserted.

[0072] As an example, both the first hollow tube and the second hollow tube are mounted on the connector. The first hollow tube has a first threaded portion, and the first connecting portion has a second threaded portion that matches the first threaded portion. For example, but not limited to, the connector can be a hollow tube. The first threaded portion includes an internal thread, and the second threaded portion includes an external thread. The connector is reliably connected to the first connecting portion of the first crossbar unit 221 via the internal thread. Similarly, the second hollow tube can have a third threaded portion, and the second connecting portion has a fourth threaded portion that matches the third threaded portion. For example, but not limited to, the third threaded portion includes an internal thread, and the fourth threaded portion includes an external thread. The connector is reliably connected to the second crossbar via the internal thread. When rotating the connector, the first connecting portion and the second connecting portion simultaneously screw into or out of the connector. That is, by operating the connector, the first crossbar and the second crossbar can be adjusted simultaneously, which is convenient. In addition, since the first crossbar and the second crossbar simultaneously screw into or out of the connector, the efficiency of adjusting the length of the second support member 22 is improved.

[0073] Furthermore, since the connecting parts are threadedly connected to the first and second crossbars respectively, the connection relationship is reliable. When the connecting parts are screwed on, there will be no accidental slippage between the connecting parts and the first crossbar or between the connecting parts and the second crossbar, thereby improving the adjustment accuracy of the second support 22.

[0074] In the above embodiments, the first crossbar unit 221 is described using the first crossbar as an example, but it is not limited thereto. As needed, the first crossbar unit 221 may also include a thin plate connected to the first crossbar. The cooperation between the thin plate and the first crossbar increases the effective interception area of ​​the guardrail assembly 2, thereby further improving the reliability of the guardrail assembly 2. As needed, the thin plate may also be provided with weight-reducing holes to further reduce the weight of the guardrail assembly 2, but this is not a limitation.

[0075] Referring again to the attached drawings, in order to further improve the safety of the guardrail assembly 2, there are at least two second support members 22. The at least two second support members 22 are spaced apart along the extension direction of the first support member 21 to prevent the gap between the second support member 22 and the support platform 1 from being too large, thereby improving the safety of the guardrail assembly 2.

[0076] Furthermore, a middle railing 23 and at least two second support members 22 are provided between two adjacent first support members 21. The at least two second support members 22 are spaced apart along the extension direction of the first support members 21, and the two ends of the middle railing 23 are movably connected to the two adjacent second support members 22. After the length of the second support members 22 is adjusted along the circumference of the support platform 1, the position of the middle railing 23 can be adjusted accordingly. For example, but not limited to, the middle railing 23 can be kept in the middle of the two adjacent first support members 21 along the circumference of the support platform 1, but it is not limited to this.

[0077] As an example, the first crossbar unit 221 and the second crossbar unit 222 can be arranged on the same horizontal plane. For example, but not limited to, the first crossbar and the second crossbar extend parallel to the support surface of the support platform 1, respectively. The length of the second support member 22 can be adjusted by the insertion of the first crossbar and the second crossbar, but this is not a limitation. The above embodiment is based on the second support member 22 being assembled with a laterally extending and movably insertable first crossbar and second crossbar, but this is not a limitation.

[0078] In addition, the second support member 22 may also include a scissor brace, which may include a first scissor brace and a second scissor brace hinged together. The top end of the first scissor brace is hinged to the top end of one of the two adjacent first support members 21, and the bottom end is hinged to the bottom end of the other of the two adjacent first support members 21. The top end of the second scissor brace is hinged to the top end of the other of the two adjacent first support members 21, and the bottom end is hinged to the bottom end of one of the two adjacent first support members 21. Thus, the second support member 22 formed by the scissor brace can have its length adjustable in the circumferential direction of the support platform.

[0079] Referring to Figure 2, the first support member 21 includes a first sub-support, a second sub-support, and a connector 24. The first sub-support and the second sub-support are spaced apart along the circumference of the support platform 1. The connector 24 connects the first sub-support and the second sub-support. The first support member 21 includes the first sub-support and the second sub-support arranged in parallel, which improves the structural strength of the first support member 21.

[0080] As an example, connector 24 includes a rigid rod of constant length, but is not limited to this.

[0081] Specifically, the support platform 1 includes a support beam 11 that extends outward in a radial pattern from the center of the support platform 1. The first sub-support and the second sub-support are respectively connected to the two sides of the support beam 11 along the circumference of the support platform 1. The placement of the first support member 21 is reasonably arranged, which improves the space utilization of the construction platform.

[0082] In addition, since the first sub-support and the second sub-support located on both sides of the support beam 11 are close to each other, higher requirements are placed on the installation accuracy of the first sub-support and the second sub-support. In order to reduce the assembly difficulty, the two ends of the connector 24 are respectively hinged to the two first support members 21, but this is not a limitation.

[0083] Specifically, referring to Figure 2, the connecting seat 213 is also provided with a third pin connecting hole, and the connecting member 24 is provided with a fourth pin connecting hole. At least one of the third and fourth pin connecting holes is an oblong hole, which can accommodate certain construction errors and reduce the assembly difficulty of the connecting member 24 with the first and second sub-supports, but this is not a limitation. As an example, the first and third pin connecting holes are respectively provided on both sides of the first support member 21 along the circumference of the support platform 1, but this is not a limitation.

[0084] Referring to Figure 2, this embodiment is illustrated by taking the alternating arrangement of the second support member 22 and the connector 24 as an example, but it is not limited thereto.

[0085] In order to accommodate support platforms 1 of different sizes and to avoid stress at the connection between the second support member 22 and the first support member 21, the two ends of the adjustable-length second support member 22 are rotatably connected to the first support member 21.

[0086] According to some embodiments of this disclosure, by setting the second support member 22 to be adjustable in length and hinged at both ends to the first support member 21, the guardrail assembly 2 is adjustable in circumferential dimension in the support platform 1, and the angle at the connection between the first support member 21 and the second support member 22 can be flexibly adjusted, thereby enabling the guardrail assembly 2 to adapt to support platforms 1 of different sizes.

[0087] To further improve the versatility of the guardrail assembly 2, the first support member 21 includes a fixed guardrail unit 212 and at least one movable guardrail unit 211. The fixed guardrail unit 212 is used to connect to the support platform 1, for example, but not limited to, it can be fixed to the support platform 1 by welding or fastener connection. At least one movable guardrail unit 211 is movably connected to the fixed guardrail unit 212 and configured to be adjustable in height relative to the support platform 1 in the height direction of the first support member 21, thereby making the height of the first support member 21 adjustable.

[0088] For ease of description, this embodiment uses the example of the first support member 21 including a fixed railing unit 212 and a movable railing unit 211, with the movable railing unit 211 being movably connected to the fixed railing unit 212 along the height direction of the support platform 1, but this is not a limitation.

[0089] Specifically, the fixed railing unit 212 can be connected to the support platform 1. For example, but not limited to, the fixed railing unit 212 can be fixed to the outer periphery of the support platform 1 by welding or fastener connection, but not limited thereto.

[0090] As an example, the fixed railing unit 212 may include a hollow tube section, and the bottom end of the movable railing unit 211 may be inserted into the hollow tube section to make the height of the first support member 21 formed by the fixed railing unit 212 and the movable railing unit 211 adjustable, but not limited thereto. If necessary, the hollow tube section may also be located at the bottom end of the movable railing unit 211, and the top end of the fixed railing unit 212 may be fitted into the hollow tube section, but not limited thereto.

[0091] To improve the connection reliability between the movable railing unit 211 and the fixed railing unit 212, an elastic pin is provided at the overlapping part of the movable railing unit 211 and the fixed railing unit 212. For example, but not limited to, taking the hollow tube part as the top of the fixed railing unit 212 and the bottom end of the movable railing unit 211 inserted into the hollow tube part as an example, the inner end of the elastic pin can be connected to the bottom end of the movable railing unit 211. The hollow tube part is provided with multiple pin holes, which are spaced apart along the height of the first support member 21. The outer end of the elastic pin can be adjusted to pass through any one of the multiple pin holes. By inserting the elastic pin into different pin holes, the relative height position of the movable railing unit 211 and the fixed railing unit 212 can be adjusted, thereby adjusting the height of the first support member 21.

[0092] According to some embodiments of this disclosure, the length of the guardrail assembly 2 along the circumference of the support platform 1 is adjustable to adapt to different support platforms 1, thereby improving the versatility of the guardrail assembly 2 to a certain extent. In addition, the height dimension of the guardrail assembly 2 in the support platform 1 is adjustable to adapt to different heights of loads on the support surface, further improving the versatility of the guardrail assembly 2.

[0093] To improve the ease of use of the guardrail assembly 2 and facilitate the entry and exit of operators from the support platform 1, as shown in Figure 1, the guardrail assembly 2 includes a guardrail body and a guardrail gate 4. The guardrail body has a guardrail notch along the circumference of the support platform 1, and the guardrail gate is openably connected to the guardrail notch.

[0094] In this embodiment, one end of the guardrail gate 4 is rotatably connected to one side of the guardrail notch along the circumference of the support platform 1, and the guardrail gate is configured such that one end is rotatably connected to one side of the support platform 1 between the open position and the locked position. Normally, the other end of the guardrail gate can be connected to the other side of the guardrail notch along the circumference of the support platform 1 by a spring lock, but this is not a limitation.

[0095] To further improve the ease of use of the guardrail gate, the guardrail gate is configured to automatically return to the locked position, for example, but not limited to, a spring hinge may be provided between one end of the guardrail gate and the guardrail body, but not limited thereto.

[0096] The above embodiments are illustrated using the example of the guardrail gate 4 being rotatably connected to the guardrail body, but are not limited thereto.

[0097] In addition, the guardrail gate 4 can also be configured as a sliding gate. One end of the guardrail gate is slidably connected to one side of the guardrail gap along the circumference of the support platform 1, and the other end of the guardrail gate can move toward the other side of the guardrail gap along the circumference of the support platform 1. The other end of the guardrail gate can also be locked on the other side of the guardrail gap to improve the safety of the guardrail gate.

[0098] To further improve the safety of the guardrail assembly 2, the construction platform also includes multiple kicking components 3. The kicking components 3 are located near the support surface and connected to the lower part of the second support member 22. At least one of the multiple kicking components 3 is length-adjustable and arranged below the length-adjustable second support member 22.

[0099] By installing a kicking component 3 above and near the support surface, the safety of the guardrail component 2 is further improved by stopping and limiting the object supported on the support surface.

[0100] An adjustable kicking assembly 3 is provided between two adjacent first supports 21 connected to the second support 22, so that it can change with the length of the second support 22. The adjustable kicking assembly 3 is located below the second support 22.

[0101] As an example, as shown in Figure 2, the length-adjustable kick assembly 3 includes a first kick unit 31 and a second kick unit 32. The first kick unit 31 is connected to one of two adjacent first support members 21 and is provided with a third connecting portion. The second kick unit 32 is connected to the other of two adjacent first support members 21 and is provided with a fourth connecting portion that matches the third connecting portion. At least one of the third connecting portion and the fourth connecting portion includes a first waist-shaped hole 33 extending circumferentially along the support platform 1. The first kick unit 31 and the second kick unit 32 are adjustablely connected through the third connecting portion and the fourth connecting portion.

[0102] As an example, the first kick plate unit 31 and the second kick plate unit 32 are connected by a fastening bolt, and the third connecting part includes a first oblong hole 33, while the fourth connecting part includes a regular round hole. When the fastening bolt passes through both the first oblong hole 33 and the regular round hole and is tightened, a reliable connection between the first kick plate unit 31 and the second kick plate unit 32 can be achieved. By loosening the fastening bolt, it can be moved within the first oblong hole 33, thereby adjusting the length of the kick plate assembly 3. Furthermore, the fourth connecting part may include an oblong hole as needed, all of which are within the scope of this disclosure.

[0103] In this embodiment, at least one of the first kick unit 31 and the second kick unit 32 includes a plate body. One end of the plate body is provided with an end plate flange 34. The end plate flange 34 is provided with a second waist-shaped hole 35 extending toward the center of the support platform 1. The end plate flange 34 is adjustablely connected to the first support member 21 through the second waist-shaped hole 35.

[0104] Specifically, one of the first ends of the first kick unit 31 and the first ends of the second kick unit 32 is provided with an end plate flange 34. The end plate flange 34 is provided with a second waist-shaped hole 35 extending toward the center of the support platform 1. The end plate flange 34 is connected to the first support member 21 through the second waist-shaped hole 35, but is not limited thereto.

[0105] According to some embodiments of this disclosure, end plate flanges 34 are respectively provided at the first end of the first kick unit 31 and the first end of the second kick unit 32, and a second waist-shaped hole 35 is provided on each end plate flange 34. The second waist-shaped hole 35 can extend toward the center of the support platform 1, so that the position of the end plate flange 34 in the support platform 1 from the center to the edge can be adjusted to adapt to the size adjustment of the support platform 1.

[0106] The aforementioned fence components can also be used as independent mechanisms for internal attachment platforms of towers.

[0107] The construction platform provided in some embodiments of this disclosure can be applied to wind turbine generator sets, for example, but not limited to, assisting in the assembly of the tower. As an example, the construction platform includes a temporary mechanical operating platform for the installation of precast concrete towers for wind turbine generator sets. This construction platform can be connected to the continuously rising tower section wall and increases in height as the construction surface of the precast concrete tower increases. The platform can support operators and tools or materials used in the tower assembly process, for example, but not limited to, tools that may include hoppers and materials that may include mortar, but are not limited to these.

[0108] Some embodiments of this disclosure provide an adjustable construction platform, which can change with the diameter of the tower, thereby improving the ease of use of the construction platform.

[0109] Referring to Figure 3, the support platform 1 may include multiple support beams 11 and a platform plate 12 disposed on the support beams 11. The support beams 11 can be used to provide the support frame of the support platform 1, and the platform plate 12 can be disposed above the support frame formed by the support beams 11 to provide a support surface. The platform plate 12 is mainly used to cover the gaps between the support beams 11 to prevent operators or materials carried on the support surface from falling through the gaps between the support beams 11, thereby improving the safety and reliability of the support platform.

[0110] Multiple support beams 11 are arranged radially. Specifically, a central support portion 15 is provided in the middle of the multiple support beams 11, and the inner ends of the multiple support beams 11 are fixed to the central support portion 15. For example, but not limited to, the inner ends of the support beams 11 can be fixed to the central support portion 15 by welding or fastener connection. The central support portion 15 connects the multiple support beams 11 into a whole, thereby improving the structural strength of the support platform.

[0111] In addition, a reinforcing rib is provided below the support beam 11. The reinforcing rib is connected to the side wall of the middle support part 15 and the bottom surface of the support beam 11, but is not limited thereto.

[0112] For ease of transportation and assembly / disassembly, the platform panel 12 includes multiple panels 121, each panel including a first panel 1211 and a second panel 1212 arranged adjacent to each other along the circumference of the supporting platform. The first panel 1211 and the second panel 1212 are generally arc-shaped and are arranged adjacent to each other along the circumference of the construction platform and spliced ​​together. As an example, the radial widths of the first panel 1211 and the second panel 1212 are substantially the same and are arranged on the same circumference. To ensure reliable connection of the panels 121 to the supporting frame, in this embodiment, the supporting beam 11 includes a first supporting beam 111, which is positioned below the joint between the panels 121 to support adjacent first panels 1211 and second panels 1212. Specifically, the circumferential ends of the first panels 1211 and the second panel 1212 rest on the upper surface of the first supporting beam 111 and are fixed to the first supporting beam 111 by clamps 13 surrounding the lower and side surfaces of the first supporting beam 111.

[0113] By overlapping the circumferential ends of the splice plate 121 onto the first support beam 111, and given the excellent structural strength of the first support beam 111, the structural strength of the circumferential ends of the splice plate 121 is improved, preventing construction workers from slipping at the splice joints and effectively reducing safety hazards. Furthermore, the circumferential ends of both the first splice plate 1211 and the second splice plate 1212 are reliably connected to the first support beam 111 by the clamp 13, further improving the connection stability of the support platform.

[0114] If bolt holes are drilled vertically through the first panel 1211, the second panel 1212, and the first support beam 111, and then connected by bolts after alignment, this connection method suffers from difficulties in hole alignment and low installation and disassembly efficiency. According to the embodiments of this disclosure, compared to simultaneously drilling holes and bolting to the platform plate and support beam, the first support beam provided in the embodiments of this disclosure forms a reliable connection with the circumferential end of the panel via a clamp 13, reducing assembly difficulty and improving assembly efficiency.

[0115] Specifically, referring to Figure 4, the clamp 13 includes a first connecting rod 131, a second connecting rod 132, and a connecting strip 133. The first connecting rod 131 and the second connecting rod 132 are respectively located on both sides of the first support beam 111 along the circumference of the support platform. The connecting strip 133 is located below the first support beam 111. The upper end of the first connecting rod 131 is fixedly connected to the first panel 1211, and the lower end is detachably connected to the first end of the connecting strip 133. The upper end of the second connecting rod 132 is fixedly connected to the second panel 1212, and the lower end is detachably connected to the second end of the connecting strip 133.

[0116] By connecting the first connecting rod 131 and the second connecting rod 132 to the first panel 1211 and the second panel 1212 respectively, and connecting the connecting strip 133 to the first panel 1211 and the second panel 1212, the first panel 1211, the second panel 1212 and the connecting strip 133 are arranged to form an accommodating space. That is, the clamp 13 has the accommodating space, and the first support beam 111 can be set in the accommodating space. The clamp 13 can surround the lower surface and side surface of the first support beam 111, and then the clamp 13 and the platform plate 12 cooperate to hold the first support beam 111 circumferentially, so as to prevent the first support beam 111 from moving or shaking relative to the platform plate 12, and so that the first support beam 111 is reliably connected to the platform plate 12.

[0117] In some embodiments, the upper end of the first connecting rod 131 can be pre-connected to the first panel 1211. This can effectively reduce the number of parts to be assembled on-site and improve on-site work efficiency. On the other hand, it can also prevent the first connecting rod 131 from being accidentally lost. The second connecting rod 132 can be pre-connected to the second panel 1212, but is not limited thereto.

[0118] Specifically, through holes are formed at both ends of the connecting bar 133, and external threads are formed at the lower ends of the first connecting rod 131 and the second connecting rod 132. The lower ends of the first connecting rod 131 and the second connecting rod 132 pass through the through holes on the connecting bar 133 and are engaged with the fastening nut.

[0119] As an example, the through hole of the connecting strip 133 can be a regular smooth hole to facilitate the passage of the first connecting rod 131 or the second connecting rod 132, but is not limited thereto. To further improve the assembly efficiency of the clamp 13, the through hole of the connecting strip 133 can also be an oblong hole, but is not limited thereto.

[0120] In this embodiment, the connecting strip 133 is shown in the form of a plate, but it is not limited thereto. The connecting strip can also be a rod as needed.

[0121] To improve the assembly efficiency of the support platform, the support beam 11 also includes multiple second support beams 112. At least one second support beam 112 is set between two adjacent first support beams 111. The inner end of the second support beam 112 is also fixed to the middle support part 15, but this is not a limitation.

[0122] In some embodiments of this disclosure, the structural parameters such as the structural strength and structural form of the second support beam 112 are the same as those of the first support beam 111. The difference is that the second support beam 112 does not need to be fixed to the platform plate 12, so as to facilitate disassembly and assembly with the platform plate 12 and improve the assembly efficiency of the support platform.

[0123] The lower surface of the panel 121 is provided with a limiting slot 14, which can be engaged with the second support beam 112. This engagement facilitates the connection between the limiting slot 14 and the second support beam 112, thereby improving the efficiency of on-site assembly and disassembly. The limiting slot 14 can also be engaged on both sides of the second support beam 112 along the circumference of the support platform, enabling accurate positioning of the second support beam 112 and preventing relative movement between the second support beam 112 and the panel 121.

[0124] As an example, each second support beam 112 may be provided with multiple limiting slots 14. The multiple limiting slots 14 may be provided at intervals along the extension direction of the second support beam 112, but are not limited thereto.

[0125] In order to reduce the number of components to be assembled on-site and improve the efficiency of on-site assembly, the limiting latch 14 can be pre-connected to the lower surface of the panel 121. For example, but not limited to, the limiting latch 14 can be fixed to the panel 121 by welding or fastener connection.

[0126] To facilitate the locking of the limiting latch 14 onto the second support beam 112, in this embodiment, the limiting latch 14 is a U-shaped latch with its opening facing downwards. In the circumferential direction of the support platform, the two ends of the U-shaped latch are respectively locked onto the two sides of the second support beam 112. Thus, by lifting the splice plate 121 upwards, the U-shaped latch can be disengaged from the second support beam 112. Conversely, when the U-shaped latch is aligned with the second support beam 112, by pressing the splice plate 121 downwards, the U-shaped latch can be connected to the second support beam 112.

[0127] In some embodiments of this disclosure, a first support beam 111 is reliably connected to the circumferential end of the panel 121 via a clamp 13, and is positioned and supported in the middle of the circumferential direction of the panel 121 by a second support beam 112, thereby providing reliable support for the panel 121. This improves assembly efficiency while ensuring the structural strength of the support platform.

[0128] Referring again to Figure 3, the platform plate 12 may include a central platform plate 122 and an annular platform plate surrounding the central platform plate 122. The central platform plate 122 may have a predetermined size. When the size of the support platform needs to be adjusted, the number of annular platform plates can be increased or decreased to adjust the size of the platform plate 12. For example, but not limited to, in the initial state, the platform plate 12 only includes the central platform plate 122. When the support platform needs to be enlarged, annular platform plates can be arranged sequentially outward along the radial direction of the support platform from the circumferential outer side of the central platform plate 122 until the radius of the support platform reaches the predetermined size. Of course, when the support platform needs to be reduced, the annular platform plates can be removed sequentially inward along the radial direction of the support platform, but this is not a limitation.

[0129] The aforementioned central platform plate 122 can be a circular plate of a predetermined size, or it can be formed by joining two semi-circular plates, or by joining at least three fan-shaped plates, but is not limited thereto.

[0130] As an example, the annular platform panel includes multiple panels 121, which are arc-shaped segments. Multiple panels 121 are arranged circumferentially around the supporting platform to form an annular platform panel, but this is not a limitation.

[0131] To improve the connection reliability of the annular platform plate, each panel 121 is reliably connected to the first support beam 111 by clamps 13 on both sides of the support platform, and at least one second support beam 112 is provided at the center of the circumference of each panel 121, but not limited thereto.

[0132] To accommodate the adjustable size of the support platform, the support beam 11 can be of adjustable length. For example, but not limited to, the support beam 11 can be a telescopic support beam composed of multiple interlocking beam segments. The support beam 11 includes movable beam segments, with at least one ring of panels 121 arranged on each movable beam segment. After removing one ring of panels 121, the corresponding movable beam segment can move inward in the radial direction by a length corresponding to the width of one panel 121. With this configuration, the panels 121 can be assembled and disassembled as needed, and the movable beam segments can also adapt to the size adjustment requirements of the support platform.

[0133] As needed, the beam segment provided in the embodiments of this disclosure can be a hollow beam, but is not limited thereto. This embodiment uses a hollow beam segment as an example for illustration. Further, this embodiment uses a U-shaped cross-section for the beam segment, but is not limited thereto. Any beam that can form an insertion cavity can be used as a hollow beam, and it is not required that the beam segment has a closed sidewall in the circumferential direction.

[0134] As an example, when it is necessary to reduce the size of the support platform, the panel 121 located on the outer ring side can be removed first. For example, but not limited to, the clamp 13 connected to the panel 121 can be removed first, and then the panel 121 can be lifted upward to separate it from the hollow tube. After the two panels 121 connected to the clamp 13 are removed, the hollow tube can be pushed inward along the radial direction of the support platform until the hollow tube is retracted inward by a length corresponding to the width of one panel 121.

[0135] The above embodiment is illustrated by taking the example of shortening the support beam 11 after removing two splice plates 121 connected to a clamp 13, but it is not limited to this. If necessary, the entire annular platform plate can be removed first, and then each hollow tube can be pushed inward in sequence to shorten the support beam 11, but it is not limited to this.

[0136] Some embodiments of this disclosure provide a support beam 11 including a plurality of fixed beam segments fixed to the outer periphery of the central support portion 15. The fixed beam segments are used to support the central platform plate 122. Since the central platform plate 122 has a predetermined size, no size adjustment is required, and therefore the fixed beam segments do not need to be adjusted in length.

[0137] The movable beam segment is located at the outer end of the fixed beam segment. When the support beam 11 is made of a hollow tube, for example, but not limited to, the inner end of the movable beam segment can be inserted into the hollow cavity at the outer end of the fixed beam segment, but this is not a limitation.

[0138] To further improve the versatility of the support platform and meet different size requirements, each support beam 11 may include at least two interlocking beam segments. The beam segment connected to the central fixed platform is referred to as the fixed beam segment, and the beam segment that can extend and retract relative to the fixed beam segment is referred to as the movable beam segment. One or more movable beam segments can be configured, and they can be interlocked and extend / retracted.

[0139] To improve the reliability of the support beam 11, the support platform may also include an anti-detachment chain 16. The anti-detachment chain 16 is used to limit the maximum radial travel of the movable beam segment and prevent the movable beam segment from detaching from the entire support beam 11. Alternatively, the movable beam segment can be driven to move radially inward by pulling the anti-detachment chain 16 to shorten its length, but this is not a limitation.

[0140] Specifically, the anti-detachment chain 16 is arranged along the length of the support beam 11, and the outermost movable beam segment is anti-detached and limited to the fixed beam segment through the anti-detachment chain 16. It can be understood that one end of the anti-detachment chain 16 is connected to the outermost movable beam segment, and the other end can be connected to the fixed beam segment, so that the outermost movable beam segment is directly anti-detached and limited to the fixed beam segment, or the other end is connected to any other movable beam segment, so that the outermost movable beam segment is indirectly anti-detached and limited to the fixed beam segment through any other movable beam segment, but this is not a limitation.

[0141] To further improve the reliability of the support beam 11, multiple anti-derailment chains 16 are provided. Anti-derailment chains 16 are provided between two movable beam segments. The anti-derailment chains 16 can be provided between the fixed beam segment and the movable sub-beam segment that can be movably connected to it, or between any two movable beam segments that can be movably connected.

[0142] Specifically, each anti-detachment chain 16 has its two ends connected between two corresponding movable beam segments. The length of the anti-detachment chain 16 is no greater than the maximum relative insertion stroke of the two movable beam segments, preventing them from detaching. It should be noted that the maximum relative insertion stroke is the maximum safe stroke for relative movement of the two movable beam segments.

[0143] Specifically, each support beam 11 includes a first hollow tube 113 located radially inner in the radial direction of the construction platform and a second hollow tube 114 located outer in the radial direction of the first hollow tube 113. The second hollow tube 114 can be inserted into the first hollow tube 113. This configuration allows the second hollow tube 114 to move smoothly radially inward to adjust the length of the support beam 11, but is not limited to this. In this embodiment, the first hollow tube 113 can be a movable beam segment or a fixed beam segment, and the second hollow tube 114 can be a movable beam segment. An anti-detachment chain 16 is provided between the first hollow tube 113 and the second hollow tube 114. For example, but not limited to, the two ends of the anti-detachment chain 16 are respectively connected to the first hollow tube 113 and the second hollow tube 114 to prevent the first hollow tube 113 from moving outward in the radial direction of the support platform, thereby preventing the second hollow tube 114 from slipping outward and detaching from the entire support beam 11, thus improving the safety of the support platform.

[0144] As an example, the two ends of the anti-detachment chain 16 are respectively connected to the radial outer ends of the first hollow tube 113 and the second hollow tube 114, which can effectively prevent the second hollow tube 114 from accidentally moving outward relative to the first hollow tube 113 in the radial direction.

[0145] Referring again to Figure 4, ear plates are provided at the outer ends of the beam segments. The ear plates are roughly U-shaped and wrap around and support the lower surface and two sides of the outer end of the beam segment. On the one hand, this effectively strengthens the end structure of the beam segment; on the other hand, the ear plates can be used for gripping when the beam segment is extended or retracted. In addition, the two ends of the anti-derailment chain 16 can be connected to the ear plates of two adjacent beam segments respectively, but this is not a limitation.

[0146] As an example, each support beam 11 is provided with anti-detachment chains 16 on both sides along the circumference of the support platform, which further improves the reliability of the support beam 11, but is not limited thereto.

[0147] In fact, anti-derailment chains 16 are provided between any two movable interlocking beam segments to improve the overall reliability of the support platform.

[0148] Referring to Figure 4, in order to further improve the reliability of the support platform, when the support platform is adjusted to its maximum size, that is, when the second hollow tube 114 extends to its maximum length relative to the first hollow tube 113, the first hollow tube 113 and the second hollow tube 114 are at the maximum relative insertion stroke position. The insertion end of the second hollow tube 114 in the first hollow tube 113 is detachably connected to the first hollow tube 113 by fastener 115.

[0149] When the support platform has its maximum size, the overlap between the insertion end of the second hollow tube 114 and the first hollow tube 113 is relatively short. At this time, the second hollow tube 114 is prone to accidentally coming out of the first hollow tube 113. By connecting the first hollow tube 113 and the second hollow tube 114 with fasteners 115, accidental coming out can be effectively avoided, which greatly improves the safety of the support platform.

[0150] When the support platform is scaled down, the second hollow tube 114 can be moved radially inward along the support platform. This increases the length of the insertion end of the second hollow tube 114 within the first hollow tube 113, effectively reducing the risk of the second hollow tube 114 accidentally detaching from the first hollow tube 113. Furthermore, due to the increased length of the insertion end, the structural strength of the overlapping portion of the first hollow tube 113 and the second hollow tube 114 is significantly improved, thereby enhancing the structural strength of the support beam 11.

[0151] Referring to Figures 1 and 5, in order to facilitate the hoisting of the support platform, a lifting ring 17 is provided on the platform plate 12. The lifting ring 17 is rotatably connected to the upper surface of the platform plate 12. It can be rotated to an upright position relative to the platform plate 12 during use, and can be stacked on the platform plate 12 after use. This prevents operators from tripping over the lifting ring 17 when walking on the support surface of the support platform, thereby further improving the reliability of the support platform, but is not limited thereto.

[0152] In this embodiment, the lifting ring 17 is generally D-shaped. The arc portion of the D-shaped lifting ring 17 is used for contact and connection with the lifting device. The central crossbeam of the D-shaped lifting ring 17 serves as a connecting rotation axis. By connecting the central crossbeam to the platform plate 12, the lifting ring 17 can rotate around the central crossbeam, thereby achieving a rotatable connection to the platform plate 12. To enable balanced lifting of the platform plate 12, multiple lifting rings 17 can be provided on the platform plate 12, but this is not a limitation.

[0153] To facilitate handling and disassembly, the platform panel 12 is equipped with movable handles 18, which can be inserted downwards and pulled upwards relative to the upper surface of the platform panel 12. As an example, each panel 121 is provided with at least two movable handles 18. For example, but not limited to, in the initial state, the movable handles 18 on the platform panel 12 can be inserted below the platform panel 12. When operators walk on the support platform, since the movable handles 18 do not form protrusions on the platform panel 12, they are less likely to trip over the operators, thus improving the reliability of the support platform. When it is necessary to disassemble the platform panel 12, the movable handles 18 can be pulled upwards to allow for gripping.

[0154] In the embodiments of this disclosure, the movable handle 18 can move up and down relative to the platform plate 12. During the process of supporting the platform to assist in the assembly of the tower, the movable handle 18 is less likely to trip the operators, thereby improving the safety of using the support platform.

[0155] Referring to Figures 3 and 5, as an example, the movable handle 18 is U-shaped, including a handle portion 181 and pins 182 connected to both ends of the handle portion 181. A platform through-hole is provided on the platform plate 12. The handle portion 181 is positioned above the platform plate 12, and the pins 182 can be inserted into the platform through-hole and fall under gravity, allowing the handle portion 181 to be supported on the platform plate 12. In this embodiment, the bottom of the U-shaped movable handle 18 forms the handle portion 181, and the two generally parallel sides of the U-shaped movable handle 18 form two pins 182. Because the two pins 182 are parallel, they easily slide downwards along the platform through-hole under gravity until the handle portion 181 is in contact with the platform plate 12.

[0156] To further improve the connection reliability between the movable handle 18 and the platform plate 12 and to prevent the pin 182 from accidentally detaching from the platform plate 12, an anti-detachment block 183 is fixedly provided at the lower end of the pin 182. The anti-detachment block 183 is located below the platform plate 12, and the diameter of the anti-detachment block 183 is larger than the diameter of the platform through hole, but is not limited thereto.

[0157] The above embodiment is illustrated by taking the movable handle 18 as being roughly U-shaped and the lower end of the plug 182 as having an anti-detachment block 183, but it is not limited thereto. The movable handle 18 can also be mouth-shaped or several-shaped, but it is not limited thereto.

[0158] Returning to Figure 3, the platform plate 12 includes a central platform plate 122 and an annular platform plate surrounding the central platform plate 122. Multiple panels 121 form the annular platform plate. The support platform 1 is also provided with an avoidance opening 19 on the annular platform plate. The construction platform also includes two reinforcing support beams 116 on both sides of the avoidance opening 19. The reinforcing support beams 116 are telescopic beams, including a fixed section 1161 located below the central platform plate 122 and a telescopic section 1162 located below the annular platform plate. An anti-derailment chain 16 is provided between the telescopic section 1162 and the fixed section 1161.

[0159] In one example of this disclosure, the reinforcing support beam 116 can also be connected to the above-mentioned panel in the form of the aforementioned clamp, which will not be described in detail here.

[0160] To avoid interference with the ladder inside the tower and to facilitate personnel access to and from the platform, a clearance opening 19 is provided on the support platform, which is located on the annular telescopic platform. By installing an anti-detachment chain 16 between the telescopic section 1162 and the fixed section 1161, the telescopic section 1162 is prevented from detaching from the fixed section 1161, thereby improving the reliability of the connection between the fixed section 1161 and the telescopic section 1162.

[0161] Furthermore, the support platform also includes a central support section 15, with multiple support beams 11 connected to the central support section 15 and arranged radially. The central support section 15 can be cylindrical, with an upper opening and a lower opening. The support platform also includes a reinforcing ring cover plate, which is movably connected to the platform plate 12 to cover the upper opening.

[0162] In this embodiment, when the middle support part 15 is in the form of a cylinder, it is provided with an upper opening. Objects above the support surface can easily fall down through this upper opening. By providing a reinforcing ring cover plate, the upper opening can be covered, thereby improving the reliability of the support platform. In addition, the reinforcing ring cover plate is movably connected to the platform plate 12. When the upper opening is needed, the reinforcing ring cover plate can be moved away from the upper opening. When the upper opening is not needed, the reinforcing ring cover plate can be placed over the upper opening.

[0163] According to embodiments of this disclosure, a platform support structure is provided, on which a platform plate 12 is mounted to form a construction platform according to embodiments of this disclosure. It is understood that the platform support structure mainly consists of a support frame formed by components such as support beams 11 and reinforcing support beams 116.

[0164] As shown in Figures 6 and 7, the platform support structure includes a central support section and multiple support beams 11. The support beams 11 are arranged around the outer periphery of the central support section, and each support beam 11 extends outward relative to the central support section. The platform support structure also includes an angle adjustment structure, which allows the support beams 11 to tilt downward at a certain angle relative to the central support section in the outward extending direction. This ensures that the support beams 11 extend horizontally when the platform support structure is suspended, thus forming a roughly horizontal support structure.

[0165] The platform support structure has multiple attachment points on its outer periphery. These attachment points connect to hooks on the inner wall of the tower, suspending the construction platform inside the tower. Because the support beam 11 is stronger than the platform plate 12, the attachment points are typically located at the outer ends of the support beam 11. Due to the large size and weight of the construction platform, and the large amount of materials and multiple workers standing on it, when suspended from the inner wall of the tower via the outer attachment points, gravity causes the middle part of the platform to sag downwards, resulting in a platform surface that is higher at the outer periphery and lower in the middle. This poses a safety hazard to workers standing on the construction platform.

[0166] In existing technologies, as shown in Figure 8, the support beam 11 is typically designed as a straight structure, lying in the same plane as the central support 15. To hoist the construction platform into the tower, multiple lifting points are installed on the platform support mechanism, usually located in the middle of the platform support structure. As shown in Figure 9, during the lifting process, the lifting mechanism connects to the lifting points in the middle of the construction platform. The outer end of the support beam 11 bends and deforms downwards under gravity, causing the upper surface of the platform plate to tilt outwards. This may cause materials placed on the platform plate to slide outwards. After the construction platform is suspended on the inner wall of the tower, as shown in Figure 10, the hooks on the outer periphery of the construction platform connect to the hooks on the inner wall of the tower. The middle part of the construction platform deforms and sags under gravity, causing the middle part of the platform to be relatively concave.

[0167] Furthermore, since the tower diameter decreases with increasing height, some construction platforms employ telescopic beams to adjust their size to accommodate the tower's inner diameter. As shown in Figures 8 to 10, the support beam 11 can be designed as a telescopic beam, comprising multiple beam segments. These segments can be hollow tubes, interlocked and telescopically adjustable to adjust the beam's length. For example, the support beam 11 includes a first hollow tube 113 and a second hollow tube 114, with the second hollow tube 114 telescopically inserted into the first hollow tube 113. Because a gap exists between the first hollow tube 113 and the second hollow tube 114, this exacerbates the downward drooping of the support beam 11's end during lifting and the upward bending of its outer end in the suspended state. The bending deformation is more pronounced when the support beam 11 includes more hollow tube segments and when the second hollow tube 114 extends significantly outward relative to the first hollow tube 113.

[0168] According to an embodiment of this disclosure, by setting an angle adjustment structure, the support beam 11 is tilted downward at a certain angle relative to the middle of the platform support structure in the direction of outward extension of the support beam 11, so that the middle of the platform support structure arches upward, and the height of the arch can compensate for the degree of depression of the middle of the platform support structure under the action of gravity, so that the support plane formed by the platform plate is basically at the same height.

[0169] According to one aspect of this disclosure, the platform support structure is generally circular to match the internal shape of the tower; however, the term "circular" here does not mean a standard circle, but may be approximately circular or a regular polygon.

[0170] According to an embodiment of this disclosure, as shown in FIG11, the platform support structure further includes a central support portion 15, around which multiple support beams 11 are arranged. The angle adjustment structure may include a first angle adjustment structure, which may be an inclined surface formed on the outer surface of the central support portion 15, and / or an inclined surface formed at the end of the support beam 11. The support beam 11 is fixedly connected to the outer wall of the central support portion 15 via the inclined surface, such that the inner end of the support beam 11 is inclined at a certain angle in the vertical direction.

[0171] As an example, the central support portion 15 is cylindrical or cylindrical with vertically extending sidewalls. The inner end of the support beam 11 has an inclined surface, and the support beam 11 is connected to the outer sidewall of the central support portion 15 through the inclined surface, such that the root of the support beam 11 is tilted upward at a certain angle relative to the outer end of the support beam 11.

[0172] According to an embodiment of this disclosure, the central support portion 15 is a stainless steel reinforcing ring, and the support beam 11 is also made of stainless steel. An inclined surface can be formed by obliquely cutting off a wedge angle from the root of the support beam 11, and then welding the root of the support beam 11 to the central support portion 15, so that the second end of the support beam 11 is inclined downward at a certain angle relative to the central support portion 15.

[0173] The angle of inclination of the support beam 11 relative to the central support 15 can be determined by calculating the degree of downward deformation of the construction platform in a suspended state based on parameters such as the weight, deflection, and weight of the materials it bears. This first angle adjustment structure ensures that the arching of the central part of the construction platform compensates for the subsidence of the central part under gravity, thus keeping the construction platform roughly in the same plane.

[0174] Because the support beam 11 has relatively high strength, the hook points for the construction platform are usually set on the support beam 11, suspending the construction platform inside the tower. However, in practical applications, not every support beam 11 needs to have a hook point; the number of hook points is determined based on the overall size, weight, and load-bearing capacity of the construction platform. Therefore, the support beam 11 includes suspension beams with hook points and non-suspension beams without hook points. For suspension beams with hook points, the outer end of the suspension beam may be pulled upwards under the action of the hook, thus keeping it in the same plane as the middle of the construction platform. However, for non-suspension beams without hook points, the outer end may droop downwards and tilt under the action of gravity, causing the suspension beam and non-suspension beam to not be in the same plane. This will cause the support plane formed by the platform support plate to warp, and the uneven support surface can easily trip workers, posing a safety hazard to workers.

[0175] According to embodiments of this disclosure, the lifting beams are provided with hanging nodes, while the non-lifting beams are not provided with hanging nodes. By making the lifting beams and non-lifting beams tilt at different angles relative to the central support 15, it is ensured that when the construction platform is in a suspended state, the multiple support beams 11 can be at as much the same height as possible, so that the support surfaces at different positions of the platform plate are generally in a horizontal plane. As an example, the upward tilt angle of the root of the lifting beam is greater than the upward tilt angle of the non-lifting beam.

[0176] Therefore, according to embodiments of this disclosure, the platform support structure may include a plurality of first support beams and a plurality of second support beams, with the first ends of the plurality of first support beams and the first ends of the plurality of second support beams connected to the central support portion. By setting a first angle adjustment structure, the second ends of the first support beams are inclined downwards at a first angle relative to the central support portion 15, and the second ends of the second support beams are inclined downwards at a second angle relative to the central support portion 15, wherein the first angle is greater than the second angle. As an example, the first support beam is a lifting point beam, and the second support beam is a non-lifting point beam.

[0177] As an example, the support beam according to an embodiment of this disclosure is composed of multiple interlocking beam segments to form a telescopic beam. As an example, the multiple beam segments can be composed of hollow tubes. As shown in FIG11, the support beam 11 includes a first hollow tube 113 and a second hollow tube 114. The first end of the first hollow tube 113 faces the center of the platform support structure and is fixedly connected to the central support portion 15. The first end of the second hollow tube 114 can be inserted into the second end of the first hollow tube 113. Since the second hollow tube 114 is inserted into the first hollow tube 113 and can extend and retract, the size of the second hollow tube 114 is smaller than the size of the first hollow tube 113, thus creating a gap between them.

[0178] According to some embodiments of this disclosure, the support beam includes a first beam segment and a second beam segment, and a second angle adjustment structure can be provided between the first beam segment and the second beam segment. As shown in Figures 11 and 12, according to an embodiment of this disclosure, a pad 715 is provided at the second end of the first hollow tube 113, and the second hollow tube 114 is supported by the pad 715. The aforementioned second angle adjustment structure can be composed of the pad 715. By providing the pad 715, the gap between the bottom wall of the first hollow tube 113 and the bottom wall of the second hollow tube 114 can be reduced, thereby reducing the degree of rotational tilt of the second hollow tube 114 relative to the first hollow tube 113, thus achieving the effect of adjusting the extension angle of the second hollow tube 114 relative to the first hollow tube 113, and preventing the second hollow tube 114 from bending and tilting at an excessive angle relative to the first hollow tube 113. As an example, both the first hollow tube 113 and the second hollow tube 114 are square tubes, the bottom plate of the square tube extends horizontally, and the pad 715 is a square pad. If a third hollow tube is also inserted into the second hollow tube 114, a pad can be provided in the outer end of the second hollow tube 114 to adjust the tilt angle of the third hollow tube relative to the second hollow tube 114.

[0179] Figure 12 shows a schematic diagram of the suspension beam when the construction platform is suspended. As shown in Figure 12, the hook applies a tensile force F to the end of the suspension beam, and the middle part of the construction platform undergoes a certain degree of downward deformation under the action of gravity G. Because the middle support part 15 arches upward relative to the support beam 11 itself according to the platform support structure of this disclosure, it can just compensate for the degree of sinking under gravity, thereby forming a roughly horizontal support structure and ensuring that the height of the platform plate is consistent throughout.

[0180] In addition, the tension F has an upward vertical component and a radial outward horizontal component along the construction platform. Under the action of the horizontal tension and gravity, the first hollow tube 113 is flattened relative to the second hollow tube 114, and with the support of the pad 715, it can further ensure that the first hollow tube 113 and the second hollow tube 114 remain in the horizontal direction.

[0181] When the construction platform is suspended, the non-suspension beam has no attachment points. However, because the downward inclination angle of the outer end of the non-suspension beam is smaller than that of the outer end under the first support, when the middle of the construction platform sinks due to gravity G, the non-suspension beam can be level with the middle of the construction platform, thus maintaining an overall horizontal state. With the support of the pad 715, the first hollow tube 113 and the second hollow tube 114 can remain straight and connected, keeping the non-suspension beam horizontal.

[0182] According to embodiments of this disclosure, the tilt of the suspension beams and non-suspension beams of the construction platform is adjusted at different angles depending on whether or not there are attachment points. This ensures that when the construction platform is suspended, the suspension beams and non-suspension beams are on the same horizontal plane, giving the construction platform a generally flat support surface and providing a safe construction environment for workers.

[0183] As shown in Figure 6, according to an embodiment of this disclosure, a clearance opening 19 is formed on the outer periphery of the platform support structure. As an example, this clearance opening 19 can be a ladder opening, opposite to a ladder on the inner wall of the tower, to avoid interference with the ladder. The platform support structure also includes two reinforcing support beams 116 located on both sides of the clearance opening 19. The reinforcing support beams 116 are fixedly connected to the bottom of the support beam 11 and are inclined downwards at a certain angle in the direction extending towards the outer periphery of the platform support structure. According to an embodiment of this disclosure, a hook point is provided at the outer end of the reinforcing support beam 116 for suspending the construction platform inside the tower. By inclining the reinforcing support beam 116 downwards relative to the outer periphery of the platform support structure at a certain angle, the platform plate on the reinforcing support beam 116 and the platform plate on the support beam 11 can remain approximately in the same plane after being suspended inside the tower.

[0184] According to an embodiment of the present disclosure, the platform support structure includes a fixed support portion located in the middle and an annular support portion located on the outer periphery of the fixed support portion. The reinforcing support beam 116 includes a fixed section 1161 located at the bottom of the fixed support portion and a telescopic section 1162 detachably connected to the bottom of the annular support portion. The telescopic section 1162 is telescopic or detachable relative to the fixed section 1161.

[0185] According to an embodiment of this disclosure, the support beam 11 includes a first hollow tube 113 and a second hollow tube 114. The second hollow tube 114 is telescopically inserted into the first hollow tube 113, thereby forming an adjustable telescopic structure, making the construction platform a support platform with an adjustable outer diameter. The first hollow tubes 113 of the multiple support beams 11 are fixedly connected to the central support portion 15, thereby forming a fixed support structure located in the middle, while the second hollow tubes 114 of the multiple support beams 11 form a ring-shaped telescopic support structure around the fixed support structure. Therefore, the platform support structure according to an embodiment of this disclosure includes a fixed support portion located in the middle and a telescopic support portion located on the outer periphery of the fixed support portion.

[0186] As shown in Figures 3 and 6, the fixed section 1161 of the reinforcing support beam 116 can be fixedly connected to the bottom of the fixed support portion, while the telescopic section 1162 is detachably connected to the bottom of the telescopic support portion. As an example, a shim can be welded between the bottom of the fixed support portion and the fixed section 1161 to adjust the tilt angle of the reinforcing support beam 116. The shim can be placed at the end where the fixed section 1161 connects to the telescopic section 1162 to adjust the tilt angle of the telescopic section 1162 relative to the fixed section 1161.

[0187] Similar to the structure of the support beam 11, the reinforcing support beam 116 may also include a first hollow tube and a second hollow tube that are interlocked, allowing the length of the reinforcing support beam 116 to be adjustable. A pad may also be provided at the opening of the first hollow tube to adjust the extension direction of the second hollow tube; this will not be described in detail here. The reinforcing support beam 116 may also include the guiding structure described below, wherein the fixed section 1161 may be configured as the first beam segment described below, and the telescopic section 1162 may be configured as the second beam segment described below.

[0188] As shown in Figures 13 and 14, the platform support structure according to this disclosure includes a lifting lug 800, which serves as a mounting point for the platform support structure. The platform support structure is generally circular, and the lifting lug 800 is arranged along the radial direction of the platform support structure. Specifically, the lifting lug 800 is provided with a lifting hole 811 or a connecting shaft for connecting to a hook (not shown), and the axis of the lifting hole 811 or the connecting shaft is perpendicular to the radial direction of the platform support structure.

[0189] When the platform support structure is suspended inside the tower by multiple hooks, the hooks are arranged circumferentially around the platform support structure, applying an upward tensile force. When the lifting lug 800 forms an angle with the radial direction, this tensile force is decomposed into a tensile force along the radial direction of the platform support structure and a lateral tensile force perpendicular to the radial direction. This lateral tensile force can damage the lifting lug and cause the hook to be torsionally twisted or even damaged. However, according to the embodiments of this disclosure, the lifting lug 800 is set along the radial direction of the platform support structure, so that after the hook and the lifting hole 811 are engaged, the tensile force applied by the hook to the lifting hole 811 is in the same plane as the lifting lug 800. This makes the platform support structure subjected to balanced forces, avoiding torsional stress between the lifting lug 800 and the support beam 11 or the reinforcing support beam 116, as well as torsional stress between the lifting lug and the hook, thereby preventing damage to the lifting lug and the hook.

[0190] According to an embodiment of this disclosure, multiple support beams 11 are generally arranged radially and extend along the radial direction of the support platform structure. Lifting lugs 800 are fixedly installed at the radial outer ends of the support beams 11, so that multiple lifting lugs 800 are spaced apart circumferentially along the platform support structure.

[0191] According to an embodiment of the present disclosure, the radially outer end of the support beam 11 may have a receiving space, and the lug 800 is generally L-shaped, including a lug body 810 and an insertion part 820 extending laterally relative to the lug body 810. The insertion part 820 can be inserted into and fixed in the receiving space at the end of the support beam 11.

[0192] Similarly, according to embodiments of the present disclosure, the radially outer end of the reinforcing support beam 116 may have a receiving space, and the lug 800 is generally L-shaped, including a lug body 810 and an insertion portion 820 extending laterally relative to the lug body 810, the insertion portion 820 being able to be inserted into and fixed in the receiving space at the end of the reinforcing support beam 116.

[0193] By inserting the insertion part 820 into the end of the support beam 11 or the reinforcing support beam 116, the contact area between the lifting lug 800 and the support beam 11 or the reinforcing support beam 116 can be increased, and the contact strength between the lifting lug 800 and the support beam 11 or the reinforcing support beam 116 can be improved, thereby enhancing the safety of the construction platform.

[0194] According to some embodiments of this disclosure, a reinforcing plate 880 is further provided at the outer end of the support beam, and the reinforcing plate 880 is fixedly connected to the outer end face of the support beam 11 and the outer end face of the lifting lug 800. According to embodiments of this disclosure, a notch 711 is provided on the upper sidewall of the accommodating space at the end of the support beam 11, and the lifting lug body 810 can be embedded in the notch 711, so that the outer surface of the lifting lug 800 is flush with the outer end face of the support beam 11. By making the outer surface of the lifting lug 800 flush with the outer end face of the support beam 11, the contact area and connection strength with the reinforcing plate 880 can be increased, preventing the lifting lug 800 from falling off the support beam. A connecting angle plate 812 can also be provided between the reinforcing plate 880 and the lifting lug body 810 to further improve the connection strength between the reinforcing plate 880 and the lifting lug 800. The lifting lug 800, support beam 11, reinforcing plate 880, and connecting angle plate 812 can be welded together to form an integral structure. Similarly, the reinforcing support beam 116, lifting lug 800, reinforcing plate 880, and connecting corner plate 812 can also be set in the manner described above.

[0195] According to another embodiment of this disclosure, a construction platform is also provided, comprising the aforementioned platform support structure and a platform plate disposed on the platform support structure. The construction platform ensures that the platform support surfaces are at substantially the same height, preventing excessive local tilting, avoiding tripping of construction personnel or slippage of materials, and improving construction safety.

[0196] In the embodiments described above, the support beam 11 is a telescopic beam, comprising multiple interlocking beam segments that can extend and retract relative to each other. The dimensions of the construction platform can be further adjusted by regulating the length of the support beam 11 to accommodate changes in the tower diameter. However, the support beam 11 is typically heavy, resulting in significant resistance during the extension and retraction adjustment process, making the adjustment difficult and reducing the installation efficiency of the construction platform.

[0197] Therefore, according to some embodiments of this disclosure, a support beam is also provided, comprising a first beam segment 100 and a second beam segment 200. The first beam segment 100 has a first insertion cavity extending along the length direction of the first beam segment 100, and the second beam segment 200 is capable of being inserted into the first insertion cavity and extending and retracting relative to the first beam segment 100, thereby adjusting the length of the support beam. Furthermore, at least one of the first beam segment 100 and the second beam segment 200 is provided with a guide structure to guide the extension and retraction operation of the second beam segment 200 relative to the first beam segment 100.

[0198] In the embodiments of this disclosure, by setting a guide structure, the second beam segment 200 can move smoothly in the first insertion cavity, avoiding large friction or mutual interference between the second beam segment 200 and the inner wall of the first insertion cavity, which would cause the telescopic operation to be stuck. This improves the smoothness of the telescopic movement of the second beam segment 200, reduces the difficulty of telescopic movement of the second beam segment 200, and avoids wear on the support beam.

[0199] According to embodiments of this disclosure, the guiding structure may include at least one rolling element. During the extension and retraction of the support beam, the rolling element causes rolling contact between the first beam segment 100 and the second beam segment 200. This relative sliding contact significantly reduces the resistance to extension and retraction. Specifically, during the extension and retraction of the second beam segment 200 relative to the first beam segment 100, due to the large weight of the second beam segment 200, if there is sliding contact between the outer surface of the second beam segment 200 and the inner surface of the first beam segment 100, the friction between them will be large, making the extension and retraction operation of the second beam segment 200 difficult. However, according to embodiments of this disclosure, by providing a guiding structure including a rolling element in at least one of the first beam segment 100 and the second beam segment 200, the friction between the inner surfaces of the second beam segment 200 and the first beam segment 100 can be reduced, thus lowering the difficulty of extension and retraction.

[0200] According to some embodiments of this disclosure, the rolling element in the guide structure may be a roller or a support roller, and the rotation axis of the roller or support roller extends along a first direction, which is perpendicular to the length direction of the support beam, such that the rolling direction of the rolling element is consistent with the extension and retraction direction of the second beam segment 200. Hereinafter, several embodiments of this disclosure will be described in detail with reference to Figures 15-22.

[0201] Figures 15 and 16 show schematic diagrams of the structure of a support beam according to some embodiments of the present disclosure. As shown in Figures 15 and 16, the first beam segment 100 may be a hollow beam (e.g., a square hollow beam), thereby forming a first insertion cavity therein. At a first end of the first beam segment 100, the first insertion cavity has a first insertion port that allows the first end of a second beam segment 200 to be inserted into the first insertion cavity through the first insertion port, and is capable of telescoping within the first insertion cavity to adjust the length of the support beam.

[0202] To reduce the weight of the supporting beam, the second beam segment 200 can also be a hollow beam. As an example, the outer contour of the second beam segment 200 matches the inner cavity of the first beam segment 100 (e.g., both the first beam segment 100 and the second beam segment 200 are square hollow beams), so that the gap between the outer sidewall of the second beam segment 200 and the inner sidewall of the first beam segment 100 is uniform. By controlling the size of the gap between the two, the spatial compactness and the stability of the telescopic operation can be improved.

[0203] According to some embodiments of this disclosure, the guiding structure includes a roller 610, as shown in Figures 15 and 16. The roller 610 is disposed parallel to the bottom wall of the first beam segment 100 and extends along the width direction of the first beam segment 100, for rolling support of the bottom wall of the second beam segment 200. Furthermore, the guiding structure may also include at least two side auxiliary rollers 620, which are respectively disposed on two opposite side walls of the first beam segment 100 for rolling contact with the side walls of the second beam segment 200.

[0204] According to some embodiments of this disclosure, by providing rollers 610 and side auxiliary rollers 620 on the bottom wall of the first beam segment 100, the sliding friction between the first beam segment 100 and the second beam segment 200 is converted into rolling friction, reducing the resistance to expansion and contraction. The side auxiliary rollers 620 constrain the horizontal lateral movement of the second beam segment 200 from both sides, effectively preventing it from swaying, deviating, or twisting during expansion and contraction, ensuring that the second beam segment 200 moves linearly along the axial direction of the first beam segment 100.

[0205] According to some embodiments of this disclosure, the support beam may further include a mounting bracket 700, which is disposed around the first insertion port on the outer wall of the first beam segment 100. A guide structure can be mounted to the mounting bracket 700. A roller 610 and at least two side auxiliary rollers 620 are disposed around the first insertion port, and the outer peripheral surface of the rolling element protrudes relative to the inner wall of the first insertion cavity, allowing the outer surface of the second beam segment 200 to be supported by the guide structure and maintain a predetermined gap with the inner surface of the first insertion cavity. By setting the mounting bracket 700 and the guide structure thereon, compared to mounting the rolling element on the inner surface of the first beam segment 100 or the outer surface of the second beam segment 200, the gap between the first beam segment 100 and the second beam segment can be effectively reduced, avoiding wobbling caused by excessive gap and improving the stability of the support beam. Furthermore, mounting the guide structure to the first beam segment via the mounting bracket simplifies the installation process and improves installation convenience.

[0206] According to some embodiments of this disclosure, by providing the idler roller 610 and the side auxiliary roller 620, the resistance of the telescopic operation can be significantly reduced, and the ease of operation and telescopic adjustment efficiency can be improved. However, in order to support the second beam segment 200, the length of the idler roller 610 is usually large, and the distance between the two axial support points of the idler roller 610 (i.e., the span) is large. When the weight of the second beam segment 200 is large, the idler roller 610 may deform, causing the middle of the idler roller 610 to sink, which increases the rotational resistance of the idler roller 610. This problem is particularly serious when the idler roller 610 is larger than the width of the second beam segment 200. When the idler roller 610 is severely deformed, it is difficult to rotate around its axis of rotation, and the rolling friction deteriorates to approximately sliding friction, making it unable to provide rolling support for the second beam segment 200. Furthermore, if a large bending moment occurs in the middle of the idler roller 610, the middle of the idler roller 610 will undergo plastic bending deformation, causing the middle of the idler roller 610 to sink below the bottom wall of the first beam segment 100. Consequently, the lower surface of the second beam segment 200 will directly contact the bottom wall of the first beam segment 100. In this situation, the function of the guiding structure is essentially lost, and the expansion and contraction resistance of the second beam segment 200 is large, making expansion and contraction operations difficult.

[0207] To address this technical problem, another type of support beam is provided according to some other embodiments of the present disclosure. Figures 17 to 22 show schematic diagrams of the structure of the support beam according to some other embodiments of the present disclosure.

[0208] Referring to Figures 17 to 22, the support beam according to an embodiment of the present disclosure includes a first beam segment 100 and a second beam segment 200. The first beam segment 100 has a first insertion cavity extending along the length direction of the first beam segment 100. The second beam segment 200 can be inserted into the first insertion cavity and extend and retract relative to the first beam segment 100, thereby adjusting the length of the support beam. Furthermore, at least one of the first beam segment 100 and the second beam segment 200 is provided with a guide structure to guide the extension and retraction operation of the second beam segment 200 relative to the first beam segment 100. As an example, the guide structure can be disposed at at least one end of the first beam segment 100 and / or at least one end of the second beam segment 200. It should be noted that the guide structure disposed at one end of the beam can be disposed on the inner side of the beam end or on the outer side of the beam end.

[0209] According to some embodiments of this disclosure, the guiding structure may include a first guiding structure 400, which includes at least two first main rolling elements 410 spaced apart in a first direction. As an example, the rotation axes of the first main rolling elements 410 are arranged parallel to the bottom wall of the first beam segment 100 or the second beam segment 200, providing rolling support for the second beam segment 200. The at least two first main rolling elements 410 are spaced apart in the first direction, meaning that the rotation axes of the at least two first main rolling elements 410 are aligned in the first direction. Their rotation axes can be aligned or staggered in the first direction, as long as they can provide rolling support for the second beam segment 200 at at least two support positions in the first direction.

[0210] In some embodiments of this disclosure, at least two first main rolling elements 410 are spaced apart in the width direction of the support beam, enabling them to provide rolling support to the bottom wall of the second beam segment 200 at at least two support positions in the width direction. Further, the first main rolling elements 410 can be rollers. Since the span of the roller is short, much smaller than the axial span of the idler roller, the roller has high bending stiffness and is not easily deformed. Furthermore, by providing at least two rollers to distribute the weight of the second beam segment 200, the load borne by each roller is small, further reducing the possibility of roller deformation. Therefore, the guide structure according to some embodiments of this disclosure can effectively avoid the problem of easy deformation of the long axis of the idler roller leading to failure of the rolling function.

[0211] When the second beam segment 200 is inserted into the first beam segment 100, the first beam segment 100 serves as the outer beam, and the second beam segment 200 serves as the inner beam. In this case, the first guide structure 400 can be positioned near the first insertion point of the first beam segment 100 (i.e., the outer beam) to provide rolling support for the weight of the second beam segment 200 during insertion. The first guide structure can be entirely installed into the first beam segment; it can be entirely installed into the second beam segment; or it can be partially installed into the first beam segment and partially installed into the second beam segment, as long as the first beam segment and the second beam segment can make rolling contact through the first guide structure. The at least two first main rolling elements of the first guide structure may not rotate along the same axis, as long as at least two points of rolling support are formed between the end of the first beam segment and the second beam segment.

[0212] According to some embodiments of this disclosure, the guiding structure may further include at least two first side auxiliary rolling elements 420, which are respectively disposed on two opposite side walls of the first beam segment 100 and roll in contact with the side wall of the second beam segment 200 to guide the extension and retraction operation of the second beam segment 200 from the side and reduce friction and resistance to the extension and retraction operation through rolling contact.

[0213] According to some embodiments of this disclosure, the guiding structure may further include at least one first top auxiliary rolling element 430 disposed on the top wall of the first beam segment 100 and in rolling contact with the lower surface of the top wall of the second beam segment 200. By providing the first top auxiliary rolling element 430, sliding friction between the top wall of the second beam segment 200 and the top wall of the first beam segment 100 can be avoided.

[0214] According to some embodiments described above in this disclosure, the guide structure is disposed on the outer side of the end face of the first beam segment 100. However, according to other embodiments of this disclosure, at least a portion of the guide structure may be disposed on the inner side of the end face of the first beam segment 100 and / or the second beam segment 200, making the structure of the support beam more compact.

[0215] As shown in Figures 17 to 21, in order to reduce the weight of the supporting beam, the first beam segment 100 and the second beam segment 200 can be configured as hollow beams, with the second beam segment 200 inserted into the first beam segment 100. According to some embodiments of this disclosure, a guide structure can be provided on the wall of the beam segment and located inside the end face of the beam segment to avoid damage to the end of the beam segment due to susceptibility to external forces.

[0216] As an example, the guide structure can be disposed in the gap between the inner surface of the first beam segment 100 and the outer surface of the second beam segment 200. However, on the one hand, in order to provide sufficient support strength, the diameter of the rolling element usually needs to be greater than 10 mm; on the other hand, in order to improve the stability of the support beam, the gap between the first beam segment 100 and the second beam segment 200 is small (e.g., about 3-5 mm), making it difficult to install the rolling element in the gap between the inner surface of the first beam segment 100 and the outer surface of the second beam segment 200. Therefore, according to one embodiment of the present disclosure, a through hole 540 (refer to FIG. 21) is provided in the wall of the hollow beam, and the rolling element is rotatably mounted on a first side of the wall of the hollow beam and protrudes through the through hole 540 to a second side of the wall, the second side being the side surface of the first beam segment 100 and the second beam segment 200 facing each other, thereby achieving rolling support between the first beam segment 100 and the second beam segment 200.

[0217] As shown in Figure 18, the first main rolling element 410, the first side auxiliary rolling element 420, and the first top auxiliary rolling element 430 are all rollers. The diameter of each roller is larger than the wall thickness of the first beam segment 100. Corresponding to the rollers, the side wall of the first beam segment 100 has through holes. The rollers are mounted on the outer side wall of the first beam segment 100 and protrude through the through holes into the first insertion cavity of the first beam segment 100 to make rolling contact with the outer surface of the second beam segment 200. For example, a support protrusion is provided on the outer side wall of the first beam segment 100, and the rollers are rotatably mounted on the support protrusion via a support shaft. By setting the installation height of the rollers, a portion of the roller can protrude relative to the inner wall of the first insertion cavity to make rolling contact with the outer side wall of the second beam segment 200.

[0218] According to one embodiment of this disclosure, the guiding structure may further include a second guiding structure 500. The second guiding structure is disposed on the second beam segment 200, so that during the extension and retraction of the second beam segment 200, it is supported by the first guiding structure 400 and the second guiding structure 500 respectively in the length direction, avoiding sliding friction with the inner surface of the first beam segment 100. As shown in FIG20, the second beam segment 200 serves as the inner beam, and the first end of the second beam segment 200 is the insertion end. The second guiding structure 500 is disposed at the first end of the second beam segment 200. In the first insertion cavity of the first beam segment 100, the first guiding structure 400 and the second guiding structure 500 provide rolling support to the front and rear ends of the insertion portion of the second beam segment 200 respectively, so that the outer surface of the second beam segment 200 always maintains a gap and rolling contact with the first beam segment 100, thereby improving the smoothness and stability of the insertion operation of the second beam segment.

[0219] As an example, the second guide structure 500 includes at least one second main rolling element 510 disposed on the bottom wall of the first end of the second beam segment 200 and protruding relative to the lower surface of the bottom wall of the second beam segment 200 to roll contact with the upper surface of the bottom wall of the first beam segment 100.

[0220] According to another embodiment of this disclosure, the guide structure may further include at least two second side auxiliary rolling elements 520. These at least two second side auxiliary rolling elements 520 may be disposed at the first end of the second beam segment 200, respectively located on two opposite sidewalls of the second beam segment 200, and protrude relative to the outer surface of the sidewalls of the second beam segment 200, so as to roll in contact with the inner surface of the insertion cavity of the first beam segment 100 when the second beam segment 200 extends or retracts relative to the first beam segment 100. Alternatively, the second side auxiliary rolling elements may also be at least partially disposed on the two opposite sidewalls of the first beam segment.

[0221] In another embodiment, the guide structure may further include at least one second top auxiliary rolling element 530, which is disposed on the top wall of the first end of the second beam segment 200 and protrudes relative to the outer surface of the top wall of the second beam segment 200 to roll in contact with the inner surface of the first insertion cavity. Of course, the second top auxiliary rolling element may also be at least partially disposed on the top wall of the first beam segment.

[0222] Figure 20 shows the structure of the guide structure installed on the second beam segment 200. Figure 21 shows the corresponding structure of the rolling elements and through holes 540, wherein part of the rolling elements is removed to show the through holes 540. Similar to the first main rolling element 410, the first side auxiliary rolling element 420, and the first top auxiliary rolling element 430 described above, the second main rolling element 510, the second side auxiliary rolling element 520, and the second top auxiliary rolling element 530 can also all be rollers, and can also be installed in a similar manner. As shown in Figures 20 and 21, through holes 540 are provided at positions corresponding to the rollers on the bottom wall, side wall, and top wall of the second beam segment 200. Multiple rollers are respectively installed in the inner cavity of the second beam segment 200 and protrude to the outside of the second beam segment 200 through the through holes 540 to make rolling contact with the first beam segment 100.

[0223] The guide structure 400 installed on the first beam segment 100 protrudes to the same height as the guide structure 500 installed on the second beam segment 200 protrudes to the same height as the guide structure 500 installed on the second beam segment 200, so that the gap between the first beam segment 100 and the second beam segment 200 remains consistent along the length of the supporting beam, thereby achieving stable support of the guide structure for the second beam segment 200.

[0224] According to embodiments of this disclosure, since the rolling surfaces of a portion of the rolling elements of the guiding structure (e.g., the first main rolling element 410, the second main rolling element 510, or the top auxiliary rolling element 430 or 530) can be protrudingly disposed between the inner surface of the outer beam and the outer surface of the inner beam, the gap between the inner beam and the outer beam can be reduced, thus constituting the second angle adjustment structure in the embodiments described with reference to Figures 11 and 12. For example, when the first main rolling element 410 and / or the first top auxiliary rolling element 430 are disposed on the inner side of the end face of the end of the first beam segment, or when the second main rolling element 510 and / or the second top auxiliary rolling element 530 are disposed on the inner side of the end face of the end of the second beam segment 200, the rolling elements function similarly to the pad 715, having an angle adjustment function, thus constituting the second angle adjustment structure. The second angle adjustment structure can adjust the inclination of the support beam 11 relative to the central support in the outward extending direction, especially adjusting the inclination angle of the inner beam relative to the outer beam, so that the support beam 11 can extend in a generally horizontal direction when the platform support structure is in a suspended state, thereby forming a generally horizontal construction platform. Although in the example described above, the first side auxiliary rolling element 420 and the second side auxiliary rolling element 520 are respectively disposed on the inner side of the end face of the beam, the installation method of the side auxiliary rolling elements is not limited to this. A similar installation method as that of the side auxiliary roller 620 in the embodiment shown in FIG. 15 of this disclosure can also be adopted. For example, a connecting structure is provided on the outer periphery of the end of the beam. The connecting structure can be a mounting bracket (e.g., a mounting ear plate) disposed on the outer periphery of the end face of the beam. The side auxiliary rolling elements can be mounted on the mounting bracket and roll in contact with the corresponding beam surface.

[0225] According to embodiments of this disclosure, to increase the telescopic length and telescopic adjustment flexibility of the support beam, the support beam may include multiple interlocking beam segments. As shown in FIG17, the support beam includes a first beam segment 100 and a second beam segment 200. The first end of the second beam segment 200 is inserted into a first insertion cavity of the first beam segment 100 and is capable of telescopic movement relative to the first beam segment 100. Furthermore, the support beam may also include a third beam segment 300, the second beam segment 200 having a second insertion cavity, and the first end of the third beam segment 300 being capable of being inserted into the second insertion cavity and telescopic movement relative to the second beam segment 200.

[0226] When the third beam segment 300 is inserted into the second beam segment 200, the second beam segment 200 serves as the outer beam and the third beam segment 300 serves as the inner beam. The inserted end of the second beam segment 200 and the inserted end of the third beam segment 300 can be provided with guide structures to enable the second beam segment 200 and the third beam segment 300 to roll into contact.

[0227] As shown in Figure 19, similar to the guide structure for the second beam segment 200 inserted into the first beam segment 100, the second end (inserted end) of the second beam segment 200 is provided with a first guide structure 400, as shown in Figure 22. The end (insertion end) of the third beam segment 300 is provided with a second guide structure 500 to guide the third beam segment 300 to roll and extend within the second insertion cavity of the second beam segment 200. Since the first guide structure 400 and the second guide structure 500 mentioned here are the same as the structures described above, they will not be described again.

[0228] The guide structure installed on the second beam segment 200 protrudes to the inner surface of the second beam segment 200 at the same height as the guide structure installed on the third beam segment 300 protrudes to the outer surface of the third beam segment 300. This ensures that the gap between the second beam segment 200 and the third beam segment 300 remains consistent along the length of the supporting beam, thereby achieving stable support of the guide structure for the third beam segment 300.

[0229] Although in the preceding embodiments and accompanying drawings, the number of the first main rolling element 410, the first side auxiliary rolling element 420, and the first top auxiliary rolling element 430 in the guiding structure of the first beam segment and the second main rolling element 510, the second side auxiliary rolling element 520, and the second top auxiliary rolling element 530 in the guiding structure of the second beam segment are one or two respectively, the number of each rolling element in this disclosure example is not limited to this embodiment, but can be adjusted accordingly based on the size and weight of the insertion. According to the support beam provided by this disclosure, the expansion and contraction efficiency of the support beam can be improved, and the difficulty of changing the diameter of the construction platform can be reduced.

[0230] According to embodiments of this disclosure, a platform support structure is provided, the platform support structure comprising a plurality of the aforementioned support beams.

[0231] According to another embodiment of this disclosure, the platform support structure further includes a central support portion 15, around which a plurality of support beams are arranged. The platform support structure also includes an angle adjustment structure, which enables the support beams to tilt downward at a certain angle relative to the central support portion 15 in the outward extending direction. The angle adjustment structure may include a first angle adjustment structure disposed between the root of the support beam and the central support portion 15 and / or a second angle adjustment structure consisting of at least one rolling element in a guide structure disposed between two adjacent beam segments.

[0232] According to another embodiment of this disclosure, a guardrail assembly as described in any of the above embodiments is also provided. Both the guardrail assembly and the platform support structure can be applied to the construction platform of the tower or to the internal accessory platform of the tower.

[0233] Embodiments of this disclosure also provide a construction platform, which includes platform panels and support beams as described above. Multiple support beams are interconnected or arranged around a central support to form a support frame. Multiple platform panels are arranged on the support frame to form the construction platform. As an example, the multiple support beams can be arranged radially. Since the support beams are telescopic beams, the length of the support beams can be adjusted by adjusting the number of beam segments and the degree of telescopic extension of each support beam, thereby adjusting the size of the support platform to flexibly adapt to changes in the tower diameter during tower installation.

[0234] The embodiments of this disclosure also provide a tower, which includes multiple cylindrical sections stacked vertically, and the multiple cylindrical sections are assembled using the aforementioned construction platform.

[0235] According to another aspect of this disclosure, a method for constructing a tower is provided, the method utilizing the construction platform provided in the preceding embodiments.

[0236] According to another aspect of this disclosure, a wind turbine generator set is provided, the wind turbine generator set including the tower as described above.
