Description

Technical Field

[0001] This disclosure pertains to tower installation and construction technology, specifically involving a construction platform, a tower, and a wind turbine generator set. Background Technology

[0002] Traditional steel towers have low stiffness and are prone to resonance, which can lead to failure. In contrast, precast concrete towers have advantages such as high weight, durability, stability, and low cost. Therefore, as the installed capacity increases and the tower height increases accordingly, concrete towers are being used more and more widely.

[0003] Concrete tower sections are typically prefabricated in sections or segments, then transported to the site for assembly and hoisting. After each concrete section is hoisted, the hooks at the top of the section need to be removed, the top of the section leveled, and adhesive applied. Therefore, a construction platform is required during the installation of the concrete tower to facilitate these operations. The construction platform is lifted by a crane to a predetermined height inside the tower, and then connected to hooks on the inner wall of the tower via a hook structure on the platform, thus suspending the platform at the predetermined height for the workers to operate.

[0004] The existing construction platform consists of support beams and platform plates mounted on the support beams, and is bolted together by drilling holes in the platform plates and support beams. However, this connection method has the problems of difficult installation due to the numerous holes, and low installation and disassembly efficiency. Utility Model Content

[0005] The main purpose of this utility model is to provide a construction platform, tower and wind turbine generator set, which reduces installation difficulty and improves operation efficiency by changing the connection structure between the platform plate and the support beam.

The construction platform also includes an anti-detachment chain, which is arranged along the length of the support beam, and the outermost movable sub-beam segment is connected to the fixed beam segment through the anti-detachment chain.

[0014] Specifically, there are multiple anti-detachment chains, and the two ends of each anti-detachment chain are respectively connected between two movably pluggable beam segments. The length of the anti-detachment chain is not greater than the maximum relative plugging stroke of the two movably pluggable beam segments to prevent them from detaching. And / or, when the two movably pluggable beam segments are located at the maximum relative plugging stroke position, the two movably pluggable components are detachably connected by fasteners.

[0015] Furthermore, the platform plate is provided with a lifting ring, which is rotatably connected to the upper surface of the platform plate. The lifting ring can be rotated to an upright position relative to the platform plate during use and can be stacked on the platform plate after use.

[0016] In another exemplary embodiment of this disclosure, a movable handle is provided on the platform plate, the movable handle being able to be inserted downward and pulled upward relative to the upper surface of the platform plate.

[0018] Specifically, an anti-detachment block is fixedly provided at the lower end of the pin, the anti-detachment block is located below the platform plate, and the diameter of the anti-detachment block is larger than the diameter of the platform through hole.

[0028] Figure 4 for Figure 3 A magnified view of a portion of the structure indicated by the middle J circle. Detailed Implementation

[0029] 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.

[0030] Reference Figure 1 This disclosure provides a construction platform 1, which includes multiple support beams 11 and a platform plate 12 disposed on the support beams 11. The support beams 11 can be used to provide a support frame for the construction platform, 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 on the support surface from falling through the gaps between the support beams 11, thereby improving the safety and reliability of the construction platform.

[0031] Continue to refer to Figure 1Multiple support beams 11 are arranged radially. Specifically, a central cylinder 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 cylinder 15. For example, but not limited to, the inner ends of the support beams 11 can be fixed to the central cylinder 15 by welding or fastener connection. This disclosure connects multiple support beams 11 into a whole by the central cylinder 15, thereby improving the structural strength of the construction platform.

[0032] In addition, a reinforcing rib is provided below the support beam 11. The reinforcing rib is connected to the side wall of the middle cylinder 15 and the bottom surface of the support beam 11, but is not limited thereto.

[0033] For ease of transportation and disassembly, the platform panel 12 includes multiple panels 121. The multiple panels 121 include a first panel 1211 and a second panel 1212 arranged adjacent to each other along the circumference of the construction platform 1. In order to reliably connect the panels 121 to the support frame, in this embodiment, the support beam 11 includes a first support beam 111. The first support beam 111 is located below the joint between the panels 121 to support the adjacent first panel 1211 and second panel 1212. Specifically, the circumferential ends of the first panel 1211 and the second panel 1212 are laid on the upper surface of the first support beam 111 and fixed to the first support beam 111 by clamps 13 surrounding the lower and side surfaces of the first support beam 111.

[0034] By overlapping the circumferential ends of the panel 121 onto the first support beam 111, and given the strong structural strength of the first support beam 111, the circumferential support strength at the joints between the panels 121 is improved, preventing construction workers from slipping at the panel joints and effectively reducing safety hazards. Furthermore, the circumferential ends of both the first panel 1211 and the second panel 1212 are reliably connected to the first support beam 111 via clamps 13, further enhancing the connection stability of the construction platform. In the prior art, bolt holes are typically drilled vertically through the first panel 1211, the second panel 1212, and the first support beam 111, and then aligned before being bolted together. This connection method is difficult to align and has low installation and disassembly efficiency. According to the embodiments of this disclosure, compared to the prior art method of simultaneously drilling holes and bolting onto the platform plate and support beam, the first support beam provided in this disclosure forms a reliable connection with the circumferential ends of the panels via clamps, reducing assembly difficulty and improving assembly efficiency.

[0035] Specifically, refer to Figure 2The 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 construction 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 splice plate 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 splice plate 1212, and the lower end is detachably connected to the second end of the connecting strip 133.

[0036] Thus, 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 by 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 this 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.

[0037] In an optional embodiment, 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] To improve the assembly efficiency of the construction 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 central cylinder 15, but this is not a limitation.

[0042] In this embodiment, 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 in this embodiment, 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 construction platform.

[0043] 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 disclosure facilitates the connection between the limiting slot 14 and the second support beam 112, thereby improving the efficiency of on-site assembly and disassembly. Furthermore, the limiting slot 14 can be engaged with both sides of the second support beam 112 along the circumference of the construction platform, thus enabling accurate positioning of the second support beam 112 and preventing relative movement between the second support beam 112 and the panel 121.

[0044] 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.

[0045] In order to reduce the number of components to be assembled on the construction platform 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.

[0046] 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 construction 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.

[0047] The first support beam 111 provided in this embodiment is reliably connected to the circumferential end of the splice plate 121 through the clamp 13, and is positioned and supported in the middle of the circumferential direction of the splice plate 121 by the second support beam 112, so as to provide reliable support for the splice plate 121. While ensuring the structural strength of the construction platform, the assembly efficiency is improved.

[0048] Continue to refer to Figure 1 and Figure 2 The platform 12 may include a central platform 122 and annular platform plates surrounding the central platform 122. The central platform 122 may have a predetermined size. When the size of the construction platform needs to be adjusted, the number of annular platform plates can be increased or decreased to adjust the size of the platform 12. For example, but not limited to, in the initial state, the platform 12 only includes the central platform 122. When the construction platform needs to be enlarged, annular platform plates can be arranged sequentially outward along the radial direction of the construction platform from the circumference of the central platform 122 until the radius of the construction platform reaches the predetermined size. Of course, when the construction platform needs to be reduced, the annular platform plates can be removed sequentially inward along the radial direction of the construction platform, but this is not a limitation.

[0049] 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.

[0050] As an example, panel 121 is an arc-shaped segment, and multiple panels 121 are arranged around the perimeter of the construction platform to form a ring-shaped platform panel, but this is not a limitation.

[0051] To improve the connection reliability of the ring platform panels, each panel 121 is reliably connected to the first support beam 111 by a clamp 13 at its circumferential end along the construction platform, and at least one second support beam 112 is provided at the circumferential center of each panel 121 along the construction platform, but this is not a limitation.

[0052] To accommodate the adjustable size of the construction platform, the support beam 11 can be length-adjustable. 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 radially inward 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 construction platform.

[0053] The beam segment provided in this disclosure may be a tubular beam as needed, but is not limited thereto. This embodiment uses a hollow tubular beam as an example for illustration. Furthermore, this embodiment uses a U-shaped cross-section for the beam segment, but is not limited thereto.

[0054] As an example, when it is necessary to reduce the size of the construction 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 construction platform until the hollow tube is retracted inward by a length corresponding to the width of one panel 121.

[0055] 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.

[0056] In fact, the support beam 11 provided in this disclosure includes multiple fixed beam segments fixed to the outer periphery of the central cylinder 15. These fixed beam segments are used to support the central platform plate 122. Since the central platform plate 122 has a predetermined size, there is no need to adjust its size, and therefore the fixed beam segments do not need to be adjusted in length.

[0057] 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.

[0058] To further improve the versatility of the construction platform and meet different size requirements, the movable beam segment may include at least two movable sub-beam segments that can be movably plugged in.

[0059] To improve the reliability of the support beam 11, the construction platform may also include an anti-detachment chain 16. The anti-detachment chain 16 is used to limit the maximum radial travel of the first hollow tube 113, preventing the first hollow tube 113 from detaching from the entire support beam 11. Alternatively, the first hollow tube 113 can be driven to move radially inward by pulling the anti-detachment chain 16 to shorten its length, but this is not a limitation.

[0060] Specifically, the anti-detachment chain 16 is arranged along the length of the support beam 11, and the outermost movable sub-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 sub-beam segment, and the other end can be connected to the fixed beam segment, so that the outermost movable sub-beam segment is directly anti-detached and limited to the fixed beam segment, or the other end is connected to any other movable sub-beam segment, so that the outermost movable sub-beam segment is indirectly anti-detached and limited to the fixed beam segment through any other movable sub-beam segment, but this is not a limitation.

[0061] 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 sub-beam segments that can be movably connected.

[0062] 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.

[0063] Specifically, each support beam 11 includes a first hollow tube 113 located radially outermost and a second hollow tube 114 located inwardly to the first hollow tube 113. The first hollow tube 113 can be inserted into the second hollow tube 114. This arrangement allows the first hollow tube 113 to move smoothly radially inward to adjust the length of the support beam 11, but it is not a limitation. In this embodiment, the first hollow tube 113 can be a movable beam segment, and the second hollow tube 114 can be either a movable beam segment or a fixed beam segment.

[0064] 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 along the radial direction of the construction platform, thereby preventing the first hollow tube 113 from slipping outward and detaching from the entire support beam 11, thus improving the safety of the construction platform.

[0065] 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 first hollow tube 113 from moving outwards relative to the second hollow tube 114 in the radial direction.

[0066] Continue to refer to Figure 2 Each movable unit has an ear plate at its outer end. When the movable unit is a rectangular hollow tube, the ear plate is roughly U-shaped, wrapping and supporting the lower surface and two sides of the outer end of the movable unit. This effectively strengthens the end structure of the movable unit and allows for gripping during the extension and retraction of the movable unit. Furthermore, the two ends of the anti-detachment chain 16 can be connected to the ear plates of two adjacent movable units, but this is not a limitation.

[0067] As an example, each of the first hollow tubes 113 is provided with anti-detachment chains 16 on both sides along the circumference of the construction platform, which further improves the reliability of the support beam 11, but is not limited thereto.

[0068] In fact, anti-derailment chains 16 are provided between any two movable interlocking beam segments to improve the reliability of the entire construction platform.

[0069] Continue to refer to Figure 2 To further improve the reliability of the construction platform, when the construction platform is adjusted to its maximum size, that is, when the first hollow tube 113 extends to its maximum length relative to the second hollow tube 114, the first hollow tube 113 and the second hollow tube 114 are at the maximum relative insertion stroke position. The insertion end of the first hollow tube 113 in the second hollow tube 114 is detachably connected to the second hollow tube 114 by fastener 115.

[0070] When the construction platform has its maximum size, the overlap between the insertion end of the first hollow tube 113 and the second hollow tube 114 is relatively short. At this time, the first hollow tube 113 is prone to accidentally coming out of the second hollow tube 114. 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 using the construction platform.

[0071] When the construction platform is scaled down, the first hollow tube 113 can be moved radially inward along the platform. This increases the length of the insertion end of the first hollow tube 113 into the second hollow tube 114, effectively reducing the risk of accidental detachment between them. Furthermore, the increased length of the insertion end significantly improves the structural strength of the overlapping portion of the first hollow tube 113 and the second hollow tube 114, thereby enhancing the structural strength of the supporting beam 11.

[0072] Reference Figure 3 and Figure 4 To facilitate the hoisting of the construction 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 construction platform, thereby further improving the reliability of the construction platform, but is not limited thereto.

[0073] 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.

[0074] 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 construction 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 construction platform. When it is necessary to disassemble the platform panel 12, the movable handles 18 can be pulled upwards to allow for gripping.

[0075] This disclosure allows the movable handle 18 to move up and down relative to the platform plate 12. During the process of using the construction 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 the construction platform.

[0076] Reference Figure 1 and Figure 4 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. Under the influence of gravity, the handle portion 181 falls and is 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 the influence of gravity until the handle portion 181 is in contact with the platform plate 12.

[0077] 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.

[0078] 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.

[0079] return Figure 1 The platform 12 includes a central platform 122 and an annular platform 122 surrounding the central platform 122. Multiple panels 121 are spliced ​​together to form the annular platform 122. The construction platform 1 is also provided with an avoidance opening 19 on the annular platform 122. The support beam 11 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 122 and a telescopic section 1162 located below the annular platform 122. An anti-derailment chain 16 is provided between the telescopic section 1162 and the fixed section 1161.

[0080] In one example of this application, the reinforcing support beam 116 can also be connected to the above-mentioned panel in the form of the above-mentioned clamp, which will not be described in detail here.

[0081] To avoid interference with the ladder inside the tower and to facilitate personnel access to and from the platform, the construction platform 1 is also equipped with a clearance opening 19 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 telescopic section 1162 and the fixed section 1161.

[0082] Furthermore, the construction platform also includes a central cylinder 15, with multiple support beams 11 connected to the central cylinder 15 and arranged radially. The central cylinder 15 has an upper opening and a lower opening. The construction platform also includes a reinforcing ring cover plate, which is movably connected to the platform plate 12 to cover the upper opening.

[0083] In this embodiment, the middle cylinder 15 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 construction platform. In addition, the reinforcing ring cover plate is movably connected to the platform plate 12. When the upper opening needs to be used, the reinforcing ring cover plate can be moved away from the upper opening. When the upper opening does not need to be used, the reinforcing ring cover plate can be placed over the upper opening.
