Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, and in particular to a wind power mast-type work platform system and a wind turbine generator set. Background Technology

[0002] With the rapid development of wind power generation technology, high-power wind turbines are becoming more and more common. As the requirements for the height of wind turbine towers become higher and higher, the installation difficulty of wind turbine towers is also increasing.

[0003] In practical applications, wind turbine towers are typically hoisted and installed segment by segment. A temporary work platform is required for each tower segment, allowing workers to align and connect the tower sections and apply adhesive at the joints. After each tower segment is installed, a ground crane is used to dismantle the work platform corresponding to the previous segment, and a new platform is erected at the opening of the newly installed tower segment for the next segment's installation. This tower erection process is cumbersome, risky, and inefficient. Furthermore, as the tower rises, its diameter decreases, necessitating the use of multiple platforms for each segment, further increasing costs. Summary of the Invention

[0004] This invention provides a wind power mast-type working platform system and a wind turbine generator set to solve the problems of high cost, complicated installation procedures and high risk in the construction of existing wind turbine towers.

[0005] This invention provides a wind power mast-type work platform system, comprising: Masts are used to install on the tower foundation and are vertically distributed inside the wind turbine tower; A lifting platform is movably mounted on the mast along the height direction of the mast; An adjustment frame is mounted on the lifting platform and is capable of rotating relative to the lifting platform; The suspended platform, which is connected to the adjusting frame, is used to transfer workers from the lifting platform to a side closer to the wind turbine tower under the action of the adjusting frame.

[0006] According to the present invention, a wind power mast-type work platform system is provided, wherein the lifting platform includes: A climbing mechanism, installed on the mast, is capable of climbing along the height direction of the mast; The support platform has a guide channel through which the mast passes. The support platform is located on the upper side of the climbing mechanism, and the adjusting frame is rotatably mounted on the support platform.

[0007] According to the present invention, a wind power mast-type working platform system is provided, wherein the mast has a rack formed along its height direction, and the climbing mechanism has a drive gear that meshes with the rack.

[0008] According to the wind power mast-type operation platform system provided by the present invention, multiple sets of guide wheels are provided in the guide channel; One portion of the multiple sets of guide wheels makes rolling contact with the first side of the mast, and another portion of the multiple sets of guide wheels makes rolling contact with the second side of the mast, with the first and second sides of the mast being arranged opposite to each other.

[0009] According to the present invention, a wind power mast-type work platform system is provided, wherein the mast includes multiple truss standard sections, and the multiple truss standard sections are connected sequentially from bottom to top along the height direction; The adjusting frame is equipped with lifting equipment, which is used to lift the standard truss section to achieve the installation of two adjacent standard truss sections.

[0010] According to the present invention, a wind power mast-type work platform system is provided, wherein the adjusting frame includes: A rotary drive mechanism is mounted on the lifting platform; A supporting column, the bottom end of which is connected to the rotary drive mechanism; The telescopic boom has a first end connected to the supporting column and a second end connected to the suspended platform.

[0011] According to the wind power mast-type work platform system provided by the present invention, the lifting equipment is connected to the supporting column; Alternatively, multiple telescopic arms may be provided, which are symmetrically distributed relative to the supporting column and connected to multiple suspended baskets one by one.

[0012] According to the present invention, a wind power mast-type operating platform system is provided, wherein the mast has a climbing structure, a guide rail structure and a fixing structure, and the climbing structure, the guide rail structure and the fixing structure are all distributed along the height direction of the mast; The ladder structure is used for workers to climb, the guide rail structure is used to guide the climbing mechanism to move along the height direction of the mast, and the fixing structure is used to fix the attachments extending along the height direction of the mast.

[0013] The present invention also provides a wind turbine generator set, comprising: Wind turbine; A wind turbine tower, which is supported at the bottom of the wind turbine generator; The wind turbine mast-type work platform system described above is installed inside the wind turbine tower.

[0014] This invention provides a wind turbine mast-type work platform system and a wind turbine generator set. By installing vertically distributed masts inside the wind turbine tower, and constructing a lifting platform and an adjusting frame connected to the masts, the system eliminates the need to temporarily construct a work platform for each layer of the wind turbine tower during layer-by-layer installation. The lifting platform's ability to move along the mast allows control of the adjusting frame to move the suspended platform to a position close to the height between adjacent layers of the wind turbine tower for alignment and connection. The adjusting frame then rotates the suspended platform to facilitate further work. Workers apply adhesive to the wind turbine tower. Simultaneously, leveraging the adjustable features of the regulating frame, the radial distribution of the suspended platform within the tower can be adjusted as the tower diameter changes. Workers, supported by the platform, can then complete the alignment and adhesive application for the variable-diameter tower without the need for multiple temporary work platforms. This design not only reduces tower construction costs but also simplifies operations, streamlines the tower construction process, improves efficiency, and reduces potential operational risks.

In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified. In the description of the embodiments of this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, B1 and / or B2 can represent: B1 existing alone, B1 and B2 existing simultaneously, and B2 existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] The following is combined with Figures 1 to 8 The present invention describes a wind power mast-type work platform system and a wind turbine generator set.

[0031] In the first aspect, such as Figure 1 and Figure 2 As shown, this embodiment of the invention provides a wind power mast-type work platform system, including a mast 1, a lifting platform 3, an adjusting frame 4, and a suspended basket 5; The mast 1 is installed on the tower foundation 9 and is vertically distributed inside the wind turbine tower 8; the lifting platform 3 is movably installed on the mast 1 along the height direction of the mast 1; the adjusting frame 4 is installed on the lifting platform 3 and can rotate relative to the lifting platform 3; the basket 5 is connected to the adjusting frame 4, and the basket 5 is used to transfer the workers from the lifting platform 3 to the side closer to the wind turbine tower 8 under the drive of the adjusting frame 4.

[0032] Understandably, mast 1 can be a truss structure and configured as a cubic column (e.g., mast 1 has a cuboid structure). Specifically, mast 1 can be a steel truss structure, which gives mast 1 good load-bearing capacity.

[0033] The mast 1 can be set close to the center area of ​​the wind turbine tower 8, and the bottom end of the mast 1 can be connected to the anchors on the tower foundation 9 by means of bolts, welding or other methods.

[0034] As for the lifting platform 3, it serves as the mounting platform for the adjusting frame 4 and its corresponding basket 5. Based on the movable setting of the lifting platform 3 along the height direction of the mast 1, the adjusting frame 4 can drive the basket 5 to move to different height positions. During the process of installing the wind turbine tower 8 layer by layer from bottom to top, it is convenient for the operators to reach the docking position between any two adjacent wind turbine towers 8 based on the basket 5, making it convenient for the operators to align the wind turbine tower 8 to be installed on the upper side. Since the adjusting frame 4 can support the basket 5 to rotate relative to the lifting platform 3, it is convenient for the operators to move around the circumference based on the basket 5 to apply glue to the docking point of two adjacent wind turbine towers 8.

[0035] For the adjusting frame 4, its bottom end is rotatably connected to the lifting platform 3, and at least a portion of the adjusting frame 4 extends to one side (e.g., the left or right side) of the lifting platform 3 to suspend the suspended basket 5 under this portion of the adjusting frame 4. The suspended basket 5 is used to carry the workers. The adjusting frame 4 can not only drive the suspended basket 5 to rotate relative to the lifting platform 3, but also has a folded state and an extended state. When the adjusting frame 4 is in the folded state, at least a portion of the suspended basket 5 is located close to the lifting platform 3, making it easy for workers on the lifting platform 3 to enter the suspended basket 5. When the adjusting frame 4 is in the extended state, at least a portion of the suspended basket 5 is located close to the inner wall of the wind turbine tower 8. This design facilitates adjusting the placement of the suspended basket 5 through the adjusting frame 4, allowing workers to reach the docking positions of wind turbine towers 8 of different diameters under the support of the suspended basket 5, and then perform docking alignment and gluing work on the wind turbine towers 8.

[0036] It should be noted that after the installation of the previous section of the wind turbine tower 8 is completed, a ground crane can be used to hoist the next section of the wind turbine tower 8 onto the upper side of the previous section. Workers can then use the suspended platform 5 to install testing equipment inside the next section of the wind turbine tower 8 (the section to be connected) to perform alignment and connection. The testing equipment includes a reflector, which can be used in conjunction with laser equipment installed on the tower foundation 9 to complete the alignment and connection of the next section of the wind turbine tower 8.

[0037] In practical applications, the reflector is installed by operators inside the wind turbine tower 8 to be docked. For example, the reflector can be installed inside the wind turbine tower 8 using multiple traction ropes, and the reflective surface of the reflector is perpendicular to the central axis of the wind turbine tower 8. The emitting unit of the laser device is used to emit laser light towards the reflector, and the receiving unit of the laser device is used to receive the laser light reflected by the reflector. This allows for distance detection based on the laser device to determine whether the central axis of the wind turbine tower 8 to be docked is vertical. When the central axis of the wind turbine tower 8 to be docked is vertical, the docking of the two adjacent wind turbine towers 8 can be achieved based on the positioning structure between the docking end faces of the two adjacent wind turbine towers 8.

[0038] In some application scenarios, a gluing device can also be installed on the suspended platform 5. When the suspended platform 5 rotates under the drive of the adjusting frame 4, the gluing device can replace the operator to automatically complete the gluing work on the wind turbine tower 8.

[0039] As can be seen from the above, the wind turbine mast-type work platform system of the present invention, by setting vertically distributed masts 1 inside the wind turbine tower 8, and setting up a lifting platform 3 and an adjusting frame 4 connected to the lifting platform 3 based on the masts 1, eliminates the need to temporarily build a work platform for each layer of wind turbine tower 8 during the layer-by-layer installation process. The lifting platform 3, with its lifting function along the mast 1, can control the adjusting frame 4 to move the basket 5 to a height position close to the adjacent two layers of wind turbine tower 8 for alignment and docking of the wind turbine tower 8 to be installed. Then, the adjusting frame 4 drives the basket 5 to rotate, facilitating the operation. Workers apply adhesive to the wind turbine tower 8. Simultaneously, leveraging the adjustable characteristics of the adjusting frame 4, the radial distribution of the suspended platform 5 within the wind turbine tower 8 can be adjusted as the diameter of the tower changes. Workers can then complete the alignment and adhesive application of the variable-diameter wind turbine tower 8 under the support of the suspended platform 5. This eliminates the need for multiple temporary work platforms for the variable-diameter wind turbine tower 8. This design not only reduces the construction cost of the wind turbine tower 8 but also facilitates operation, simplifies the construction process, improves work efficiency, and reduces potential operational risks during the construction of the wind turbine tower 8.

[0040] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the lifting platform 3 includes a climbing mechanism 31 and a support frame 32; the climbing mechanism 31 is installed on the mast 1 and can climb along the height direction of the mast 1; the support frame 32 has a guide channel 320, the mast 1 passes through the guide channel 320, the support frame 32 is installed on the upper side of the climbing mechanism 31, and the adjusting frame 4 is rotatably installed on the support frame 32.

[0041] Understandably, the support platform 32 serves not only as a platform for supporting the adjustment frame 4 and the basket 5, but also as a guide channel 320 to guide the climbing mechanism 31 as it climbs along the mast 1, ensuring the stability and safety of the climbing mechanism 31 as it climbs along the mast 1.

[0042] In practical applications, the climbing mechanism 31 can be set to climb on the side of the mast 1. The climbing mechanism 31 can be a car elevator, traction elevator, rack and pinion type elevator, etc., which are known in the art, and there is no specific limitation.

[0043] In some embodiments, such as Figure 3 and Figure 4 As shown, the mast 1 has a rack 115 formed along its height direction, and the climbing mechanism 31 has a drive gear 313, which meshes with the rack 115.

[0044] It is understandable that, based on the meshing arrangement between the drive gear 313 and the rack 115, when the drive gear 313 rotates, it can be ensured that the drive gear 313 rolls along the extension direction of the rack 115, so that the entire climbing mechanism 31 moves stably up and down along the mast 1.

[0045] like Figure 3 As shown, the climbing mechanism 31 includes a frame 311, a gear drive mechanism 312, and a drive gear 313. The frame 311 is movably mounted on the side of the mast 1 along the height direction of the mast 1. The gear drive mechanism 312 is mounted on the frame 311, and the output end of the gear drive mechanism 312 is coaxially connected to the drive gear 313. The gear drive mechanism 312 can be a geared motor.

[0046] To ensure that the climbing mechanism 31 obtains a sufficiently large climbing force, the climbing mechanism 31 can be configured with multiple gear drive mechanisms 312. The multiple gear drive mechanisms 312 are arranged side by side along the extension direction of the rack 115, and the multiple drive gears 313 corresponding to the multiple gear drive mechanisms 312 are configured to rotate synchronously and mesh with the same rack 115.

[0047] In practical applications, as the wind turbine tower 8 is assembled layer by layer, the mast 1 is built from bottom to top. The rack 115 can serve as part of the mast 1 to transmit the vertical load on the mast 1, guide the climbing mechanism 31 to move along the height direction of the mast 1, and cooperate with the drive gear 313 of the climbing mechanism 31 to convert the rotational motion of the drive gear 313 into the linear motion of the climbing mechanism 31. At the same time, the meshing point of the rack 115 and the drive gear 313 together resists the gravity load of the climbing mechanism 31.

[0048] In some embodiments, such as Figure 3 and Figure 4 As shown, multiple sets of guide wheel groups 321 are provided in the guide channel 320; a portion of the multiple sets of guide wheel groups 321 rolls in contact with the first side of the mast 1, and another portion of the multiple sets of guide wheel groups 321 rolls in contact with the second side of the mast 1, with the first side and the second side of the mast 1 arranged opposite to each other.

[0049] Understandably, based on the rolling contact between the multiple sets of guide rollers 321 and the mast 1, a stable horizontal constraint can be established between the support platform 32 and the mast 1, and the support platform 32 can be smoothly raised and lowered along the mast 1.

[0050] In practical applications, each guide wheel group 321 may include multiple guide wheels, which are arranged side by side along the height direction of the mast 1; wherein, the multiple guide wheels can be configured to roll into contact with the main column 111 or rack 115 of the mast 1.

[0051] In some embodiments, such as Figure 1 and Figure 5 As shown, the mast 1 includes multiple truss standard sections 11, which are connected sequentially from bottom to top along the height direction; The adjustment frame 4 is equipped with a lifting device 6, which is used to lift the standard truss section 11 to realize the installation of two adjacent standard truss sections 11.

[0052] It is understood that by setting up a lifting device 6 on the adjustment frame 4 in this embodiment, the standard truss section 11 can be hoisted during the process of building the wind turbine tower 8 from bottom to top, so as to simultaneously complete the sequential construction of multiple standard truss sections 11 from bottom to top, ensuring that the height of the entire mast 1 obtained from the construction meets the installation requirements of the wind turbine tower 8.

[0053] In the actual installation process, along the height direction, the bottom end of a truss standard section 11 located at the bottom is connected to the tower foundation 9, and the bottom end of a truss standard section 11 located above is connected to the top end of a truss standard section 11 located below, so as to realize that multiple truss standard sections 11 are connected sequentially along the height direction. This design is simple and convenient to operate, and can be used to build each truss standard section 11 sequentially from bottom to top as the wind turbine tower 8 is built upward, so as to provide an operating platform for the construction of each layer of wind turbine tower 8. Moreover, the entire mast 1 formed by the construction forms a truss structure with good stability and strong load-bearing capacity.

[0054] It should be noted that each truss standard section 11 can be configured as a cubic truss structure, and the mast 1 obtained by stacking multiple truss standard sections 11 forms a cubic column.

[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, the adjustment frame 4 includes a rotary drive mechanism 41, a support column 42, and a telescopic arm 43; the rotary drive mechanism 41 is mounted on the lifting platform 3, and the bottom end of the support column 42 is connected to the rotary drive mechanism 41; the first end of the telescopic arm 43 is connected to the support column 42, and the second end of the telescopic arm 43 is connected to the suspended basket 5.

[0056] Understandably, since the lifting equipment 6 is mounted on the adjusting frame 4, in order to facilitate the lifting of the truss standard section 11 by the lifting equipment 6 for installation, the lifting equipment 6 must be offset from the guide channel 320 of the support platform 32. Therefore, in the installation layout of the adjusting frame 4, the slewing drive mechanism 41 needs to be mounted on the support platform 32 and positioned to one side of the guide channel 320.

[0057] like Figure 2 As shown, to prevent the adjustment of the position of the lifting frame 4 on the suspended basket 5 from affecting the normal operation of the lifting equipment 6, the lifting equipment 6 can be connected to the supporting column 42. For example, the lifting equipment 6 includes a lifting arm 61 and a lifting attachment 62. The first end of the lifting arm 61 is connected to the top end of the supporting column 42, and the lifting attachment 62 is located at the second end of the lifting arm 61. The lifting attachment 62 can be an electric hoist or a hook.

[0058] In some embodiments, in order to facilitate the hoisting operation of the hoisting equipment 6 on the standard truss section 11, the hoisting boom 61 can be a telescopic boom, and a luffing mechanism, such as a luffing cylinder, can be provided between the hoisting boom 61 and the supporting column 42 to adjust the pitch angle of the hoisting boom 61 relative to the supporting column 42 based on the luffing mechanism.

[0059] In some embodiments, in order to facilitate the rotation of the adjustment frame 4, the rotation drive mechanism 41 may be provided with a rotation support, a drive motor and a transmission assembly; the rotation support is provided on the lifting platform 3 (e.g., the support frame 32); the drive motor is provided on one side of the rotation support; the transmission assembly includes a gear and a transmission gear ring, the gear and the transmission gear ring are meshed, the gear and the output end of the drive motor are coaxially connected, the transmission gear ring is coaxially connected to the bottom end of the support column 42 and is rotatably provided on the rotation support.

[0060] It should be noted that the telescopic boom 43 can be configured to be set vertically relative to the supporting column 42 so as to adjust the radial distribution position of the basket 5 in the wind turbine tower 8 based on the telescopic movement of the telescopic boom 43.

[0061] like Figure 1 and Figure 2 As shown, the suspended platform 5 is configured to be suspended on the lower side near the second end of the telescopic boom 43. A support member is provided at the second end of the telescopic boom 43. The support member is configured to abut against the inner wall of the wind turbine tower 8. Based on the supporting effect of the support member, a force point is formed on the side wall of the wind turbine tower 8, which can ensure the stability of the entire telescopic boom 43. This ensures that the suspended platform 5 is stably suspended on the lower side of the telescopic boom 43, making the suspended platform 5 less prone to shaking and helping to improve the safety of the workers operating based on the suspended platform 5.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, there are multiple telescopic arms 43, which are symmetrically distributed relative to the supporting column 42 and are connected to multiple suspended baskets 5 one by one.

[0063] Understandably, by symmetrically distributing multiple telescopic booms 43 relative to the supporting column 42, the balanced force distribution of the entire adjusting frame 4 can be ensured, which is beneficial for the adjusting frame 4 to rotate stably on the lifting platform 3. At the same time, multiple suspended baskets 5 can be deployed based on the multiple telescopic booms 43, which facilitates multiple workers to work together under the support of multiple suspended baskets 5, thereby improving the installation efficiency of the wind turbine tower 8.

[0064] In some embodiments, such as Figure 5 and Figure 6 As shown, the mast 1 has a climbing structure 101, a guide rail structure 102, and a fixing structure 103. The climbing structure 101, the guide rail structure 102, and the fixing structure 103 are all distributed along the height direction of the mast 1. The climbing structure 101 is used for workers to climb, the guide rail structure 102 is used to guide the climbing mechanism 31 to move along the height direction of the mast 1, and the fixing structure 103 is used to fix the attachments that extend along the height direction of the mast 1.

[0065] It is understood that the accessories shown in this embodiment include at least one of the following: wind turbine transmission cable, power supply and communication cable, lighting system 131, and sliding contact line 132.

[0066] Because the mast 1 has a ladder structure 101, a guide rail structure 102, and a fixing structure 103, a multi-functional integrated design can be achieved based on the mast 1. This allows the mast 1 to integrate ladder functions, guidance functions for lifting equipment (such as lifting platform 3), and load-bearing functions for various accessories. Personnel and / or materials can be lifted and lowered by the lifting equipment. Personnel can also reach the ladder structure 101 from the lifting equipment to inspect the accessories carried by the mast 1. In an emergency, the ladder structure 101 can also serve as an emergency passage for personnel to quickly move down to the tower foundation 9.

[0067] In some embodiments, such as Figure 5 and Figure 6 As shown, the fixing structure 103 can be a first fixing hole 1031, a second fixing hole 1032, and a third fixing hole 1033 formed on the side wall of the mast 1. The first fixing hole 1031 is used to install the first cable clamp 121, and the wind turbine power cable can be installed based on the first cable clamp 121. The second fixing hole 1032 is used to install the second cable clamp 122, and the power supply and communication cable can be installed based on the second cable clamp 122. The third fixing hole 1033 is used to install the lighting system 131, such as a lighting fixture.

[0068] In some embodiments, such as Figure 6 As shown, the accessory also includes a sliding contact line 132, which can be configured to extend along the extension direction of the ladder structure 101. The sliding contact line 132 is electrically connected to the power supply and is configured to slide in contact with power-taking components (e.g., brushes) on the lifting equipment, thereby enabling power supply to the lifting equipment that moves up and down along the mast 1 based on the sliding contact line 132.

[0069] In some embodiments, such as Figure 5 and Figure 6 As shown, a passageway 1101 is formed inside the standard truss section 11. The passageway 1101 extends through the standard truss section 11 along the height direction to allow workers to move up and down along the ladder structure 101. The ladder structure 101, the guide rail structure 102, and the fixing structure 103 are respectively formed on the side of the standard truss section 11. A manhole 1102 is formed on the side of the standard truss section 11. The manhole 1102 is used for workers to pass through and enter the passageway 1101.

[0070] It is understandable that when multiple truss standard sections 11 are connected sequentially along the height direction, the passageways 1101 inside the multiple truss standard sections 11 are connected sequentially, which makes a vertical passageway formed inside the entire mast 1. Workers can enter the passageway 1101 through the manhole 1102 of any truss standard section 11, and then climb up and down along the ladder structure 101 to reach the position of the mast 1.

[0071] Since the ladder structure 101, guide rail structure 102 and fixed structure 103 are respectively formed on the side of the truss standard section 11, and the workers climb along the ladder structure 101 inside the truss standard section 11, the workers are close to the various accessories fixed by the fixed structure 103, which makes it convenient to inspect these accessories.

[0072] In some application scenarios, such as when the lifting equipment malfunctions, personnel can reach the manhole 1102 through the top platform of the lifting equipment, and then enter the passageway 1101 through the manhole 1102. At this time, personnel can either climb up the ladder structure 101 to repair the relevant accessories, or use the ladder structure 101 as an emergency passage to quickly reach the ground.

[0073] In some embodiments, such as Figure 6 As shown, in order to ensure the safety of personnel climbing the ladder structure 101, a lifeline 133 is provided inside the mast 1, and the lifeline 133 extends along the extension direction of the ladder structure 101.

[0074] Understandably, lifeline 133 is used to slide with the fall arrestor worn by the person. When the person is climbing up and down the ladder structure 101 normally (for example, the climbing speed is lower than the set value), the fall arrestor will slide up and down normally along lifeline 133. When the person experiences a sudden drop, for example, the person's falling speed is higher than the set value, the centrifugal trigger mechanism or cam mechanism inside the fall arrestor will lock instantly due to the sudden change in speed. This will put the fall arrestor in a locked state immediately and lock it to lifeline 133 to provide safety protection for the person.

[0075] In practical applications, the lifeline 133 can adopt a guide rail groove. Multiple locking ports can be set on the bottom of the guide rail groove along its extension direction. The bottom of the guide rail groove is connected to the ladder structure 101. The groove opening of the guide rail groove faces the inside of the truss standard section 11. This design ensures that the lifeline 133 is a rigid structure, which can solve the problem of swaying and tangling that traditional flexible lifelines 133 (such as steel wire ropes) are prone to during use.

[0076] Meanwhile, the fall arrestor can be a slider-type fall arrestor, in which the roller assembly is movably mounted in the guide rail groove. When a person is climbing up and down the ladder normally, the slider mechanism of the slider-type fall arrestor separates from the locking port of the guide rail groove. However, when a person experiences a loss of speed and falls, the slider mechanism of the slider-type fall arrestor locks into place with the locking port of the guide rail groove to prevent the person from continuing to fall.

[0077] In some embodiments, such as Figure 5 As shown, at least one standard truss section 11 corresponding to the mast 1 is provided with a mounting part 1103, which is used to attach to wearable devices.

[0078] It is understood that the mounting part 1103 can be a mounting interface or a mounting post, without specific limitations. When the operator is carrying out maintenance, the operator wears the wearable equipment on his / her body and can hang the wearable equipment on the mounting part through the mounting attachment (such as a hook). This design makes it easy for the operator to adjust the position within the standard truss section 11 based on the support provided by the mounting part 1103, which facilitates safe maintenance operations.

[0079] In some embodiments, such as Figure 5 As shown, the truss standard section 11 includes multiple main columns 111, multiple footrails 112, and multiple cross braces 113. The multiple main columns 111 are arranged circumferentially, and each main column 111 extends along the height direction. Two adjacent main columns 111 form part of the guide rail structure 102. The multiple footrails 112 are arranged sequentially along the height direction between two adjacent main columns 111 that form the guide rail structure 102 to form part of the ladder structure 101. One of the two adjacent main columns 111 of the guide rail structure 102 can be replaced by a rack 115, or the side wall of one of the two adjacent main columns 111 of the guide rail structure 102 can be provided with an integrated rack 115. The multiple cross braces 113 are arranged between any two adjacent main columns 111 other than the plane where the ladder structure 101 is located, and the cross braces 113 are provided with a fixing structure 103.

[0080] It is understood that the main column 111 can be a circular or square column, without specific limitations. The main column 111 not only serves as the core load-bearing part of the truss standard section 11, but also as the guide rail structure 102 used to guide the lifting equipment. Multiple main columns 111, combined with multiple foot rods 112 and multiple cross braces 113, realize the construction of the entire truss standard section 11, ensuring that the entire truss standard section 11 has a compact structure, strong structural strength, and can reliably guide the lifting equipment. The truss standard section 11 can be formed into an integral welded component based on the main columns 111, foot rods 112, and cross braces 113.

[0081] Meanwhile, when multiple truss standard sections 11 are stacked sequentially along the height direction, the main columns 111 corresponding to the multiple truss standard sections 11 are connected one by one along the height direction. This design can ensure that the vertical load is transferred sequentially from top to bottom along the main columns 111 corresponding to each truss standard section 11, which is beneficial to ensuring the stability of the entire mast 1 structure and has good load-bearing capacity.

[0082] Since multiple step rods 112 are arranged sequentially along the height direction between two adjacent main columns 111 that serve as guide rail structure 102, the ladder structure 101 formed by multiple step rods 112 can be used as part of the entire truss standard section 11. This design not only ensures the structural strength of the entire truss standard section 11, but also reduces the problems of increased volume and structural bulkiness caused by the additional ladder structure 101.

[0083] Furthermore, by setting a fixing structure 103 on each cross brace 113, such as the fixing structure 103 including the first fixing hole 1031, the second fixing hole 1032 and the third fixing hole 1033 shown in the above embodiment, this design facilitates the use of the fixing function of the fixing structure 103 to arrange related accessories along the standard section 11 of the truss.

[0084] As can be seen from the above, based on the structural design of the truss standard section 11, each truss standard section 11 integrates the functions of the climbing structure 101, the guiding function for the lifting equipment, and the load-bearing function for various accessories. Therefore, when multiple truss standard sections 11 are stacked sequentially along the height direction, it can be ensured that the stacked mast 1 naturally forms the climbing structure 101 and the guide rail structure 102 extending along the height direction, as well as the fixed structure 103 arranged along the height direction.

[0085] In some embodiments, such as Figure 5 As shown, in order to further enhance the structural strength of the entire truss standard section 11, the truss standard section 11 also includes diagonal bracing 114, which is provided between any two adjacent horizontal bracings 113 and / or between any adjacent main column 111 and horizontal bracing 113, except for the plane where the climbing structure 101 is located.

[0086] In practical applications, since multiple main columns 111 are arranged circumferentially, a passageway 1101 can be formed on the inner side of the truss standard section 11 built based on multiple main columns 111. The main columns 111, combined with multiple footboards 112, multiple cross braces 113 and multiple diagonal braces 114, form a connecting structure to serve as the side wall of the truss standard section 11. A manhole 1102 for workers to enter and exit the passageway 1101 can be formed on this side wall based on two diagonal braces 114 and one main column 111.

[0087] For any given truss standard section 11, which can be a cubic truss structure, there are four main columns 111. Based on these four main columns 111, several foot braces 112 and several cross braces 113 are arranged. The four main columns 111 are located at the four corners of the truss standard section 11. The foot braces 112 are located between two main columns 111 on the first side of the truss standard section 11. For the other sides of the truss standard section 11, the cross braces 113 and diagonal braces 114 can be adaptively configured according to actual application requirements.

[0088] like Figure 5 and Figure 6 As shown, when the truss standard section 11 is a cubic truss structure, a sliding contact line 132 can be installed on the first side of the truss standard section 11, a manhole 1102 for personnel access passage 1101 can be installed on the second side of the truss standard section 11, a fan power cable can be installed on the third side of the truss standard section 11 through a first cable clamp 121, a power supply and communication cable can be installed on the fourth side of the truss standard section 11 through a second cable clamp 122, and a lighting system 131 can also be directly installed on the fourth side of the truss standard section 11. The first side of the truss standard section 11 is perpendicular to the second and third sides, the second side is parallel to the third side, and the first side is parallel to the fourth side.

[0089] In some embodiments, such as Figure 4 and Figure 5 As shown, the bottom end of the main column 111 of the upper truss standard section 11 is inserted into the top end of the main column 111 of the lower truss standard section 11; the cross brace 113 at the bottom end of the upper truss standard section 11 is opposite to the cross brace 113 at the top end of the lower truss standard section 11 along the height direction and is connected by a locking structure.

[0090] Understandably, by inserting the bottom end of the main column 111 of the upper truss standard section 11 into the top end of the main column 111 of the lower truss standard section 11, it is convenient to connect the main columns 111 corresponding to each truss standard section 11 sequentially from bottom to top along the height direction, ensuring that these main columns 111 are coaxially distributed along the height direction, and that two adjacent main columns 111 form constraints along the horizontal direction, so as to better transfer vertical loads based on these main columns 111.

[0091] For example, such as Figure 5As shown, along the height direction of the mast, the top of the main column 111 has a plug-in portion 11101 and the bottom of the main column 111 has a receiving portion 11102. The plug-in portion 11101 of the main column 111 of the lower truss standard section 11 is used to be inserted into the receiving portion 11102 of the main column 111 of the upper truss standard section 11, so that the two adjacent main columns 111 of the upper and lower sections can form a plug-in fit.

[0092] Specifically, the insertion part 11101 can be a protrusion, and the receiving part 11102 can be a groove that fits the protrusion; wherein, the shape of the protrusion can be cylindrical or cubic, and there is no specific limitation thereto.

[0093] At the same time, by aligning the horizontal brace 113 at the bottom of the upper truss standard section 11 with the horizontal brace 113 at the top of the lower truss standard section 11 along the height direction and connecting them with locking components, a stable connection between the two adjacent upper and lower truss standard sections 11 can be further achieved.

[0094] In practical applications, such as Figure 5 As shown, the locking structure can be a locking bolt and a connecting hole 1131, with the locking bolt in... Figure 5 Not shown in the diagram; the cross brace 113 at the bottom of the upper truss standard section 11 and the cross brace 113 at the top of the lower truss standard section 11 can both be provided with corresponding connecting holes 1131 along the height direction. Each cross brace 113 can be provided with multiple connecting holes 1131. The multiple connecting holes 1131 of the upper cross brace 113 and the multiple connecting holes 1131 of the lower cross brace 113 are arranged one-to-one. The upper and lower corresponding cross braces 113 can be connected into one unit by locking bolts passing through the upper and lower corresponding connecting holes 1131.

[0095] In some embodiments, such as Figure 1 and Figure 7 As shown, the wind power mast-type operating platform system of the present invention further includes: at least one support component 2, which is adjustablely disposed between the mast 1 and the inner wall of the wind turbine tower 8.

[0096] Understandably, in the wind power generation field, lifting equipment is typically guided up and down using ladder guide rails inside the wind turbine tower 8, and workers also use these ladder guide rails to move up and down. The ladder guide rails are mainly attached to the inner wall of the wind turbine tower 8 via numerous connectors (such as embedded parts or welded parts). This structural design requires a large number of connectors, resulting in high costs. Furthermore, the contraction of the wind turbine tower 8 after tensioning can cause the ladder guide rails to twist and deform, affecting the normal operation of the lifting equipment.

[0097] In this invention, since the mast 1 is connected to the inner wall of the wind turbine tower 8 through at least one support component 2, this design utilizes the lateral support provided by the support component 2 to prevent the mast 1 from shifting laterally within the wind turbine tower 8. This helps to shorten the slenderness ratio of the mast 1, increasing its longitudinal stability while ensuring its load-bearing capacity. Compared to existing ladder rail construction designs, this embodiment eliminates the need for numerous connectors (such as embedded parts or welded parts) between the mast 1 and the inner wall of the wind turbine tower 8, allowing the mast 1 to be stably installed vertically within the wind turbine tower 8, effectively reducing construction costs. In particular, during the tensioning of the wind turbine tower 8, the support component 2 can adaptively adjust to the tensioning and contraction of the wind turbine tower 8, providing lateral support to the mast 1 while effectively preventing twisting and deformation of the mast 1 caused by the tensioning and contraction of the wind turbine tower 8, ensuring that the lifting equipment can move normally up and down along the mast 1.

[0098] In some embodiments, such as Figure 1 and Figure 4 As shown, the wind power mast-type work platform system of the present invention also includes an installation frame 7, which is rotatably disposed on one side of the lifting platform 3. The installation frame 7 is used to flip between the mast 1 and the inner wall of the wind turbine tower 8 so that the workers can install the support component 2 based on the installation frame 7.

[0099] It is understandable that one side of the mounting platform 7 is rotatably connected to one side of the lifting platform 3 through a hinge structure, so that the mounting platform 7 can be rotatably set on one side of the lifting platform 3. This design can ensure that the mounting platform 7 can be rotated at a large angle relative to the lifting platform 3, thereby ensuring the working range of the operator when installing the support component 2 based on the mounting platform 7.

[0100] like Figure 1 As shown, in the case where the lifting platform 3 includes a climbing mechanism 31 and a support frame 32, the mounting frame 7 is rotatably mounted on one side of the climbing mechanism 31.

[0101] In practical applications, two mounting platforms 7 can be set up, positioned opposite each other on both sides of the climbing mechanism 31. The installation height of each mounting platform 7 is no higher than the installation height of the supporting platform 32, and the rotation angle of each mounting platform 7 relative to the climbing mechanism 31 ranges from 0° to 180°. Based on the setup of two mounting platforms 7, it can be ensured that multiple operators can work collaboratively on different mounting platforms 7, with the collaborative work area covering a 360° horizontal workspace.

[0102] In some examples, a drive mechanism may be provided between the mounting platform 7 and the climbing mechanism 31 to drive the mounting platform 7 to rotate relative to the climbing mechanism 31. The drive mechanism may be a telescopic rod known in the art, with one end of the telescopic rod rotatably connected to the mounting platform 7 and the other end rotatably connected to the climbing mechanism 31.

[0103] The installation platform 7 includes a standing platform and guardrails surrounding the standing platform. Workers can install the support components 2 on the standing platform. The guardrails provide protection and ensure the safety of the workers.

[0104] In some embodiments, such as Figure 7 As shown, the support assembly 2 includes: a first mounting base 21, a second mounting base 22, and a connecting bracket 23; the first mounting base 21 is used to connect to the inner wall of the wind turbine tower 8; the second mounting base 22 is connected to the mast 1; the connecting bracket 23 is movably disposed between the first mounting base 21 and the second mounting base 22, and the connecting bracket 23 can move relative to at least one of the first mounting base 21 and the second mounting base 22 in the height direction.

[0105] Understandably, the first mounting base 21, the second mounting base 22, and the connecting bracket 23 are connected in sequence to establish a stable horizontal constraint between the mast 1 and the inner wall of the wind turbine tower 8, providing lateral support for the mast 1 and ensuring the stability of the mast 1 in the longitudinal distribution within the wind turbine tower 8.

[0106] Meanwhile, by setting the connecting bracket 23 to move along the height direction relative to at least one of the first mounting base 21 and the second mounting base 22, it is possible to ensure that the connecting bracket 23 can adaptively adjust its position relative to at least one of the first mounting base 21 and the second mounting base 22 when the wind turbine tower 8 is tensioned and contracted. This allows the entire support assembly 2 to provide lateral support to the mast 1 while effectively preventing the mast 1 from twisting and deforming due to the tensioning and contraction of the wind turbine tower 8, thus ensuring that the lifting equipment can move up and down normally along the mast 1.

[0107] In practical applications, such as Figure 7 As shown, the second mounting base 22 has at least one connecting arm on the side facing the mast 1, and the connecting arm is connected to the mast 1 by a clamp 222; for example, the connecting arm is connected to the main column 111 of the mast 1 by the clamp 222; wherein, the connecting arm is connected to the clamp 222 by bolts or other locking components, and a locking opening is formed between the connecting arm and the clamp 222 for circumferentially enclosing the main column 111.

[0108] In some embodiments, such as Figure 7As shown, the connecting bracket 23 includes a first frame 231 and a second frame 232; the first end of the first frame 231 is detachably connected to the first mounting base 21; the first end of the second frame 232 is detachably connected to the second end of the first frame 231, and the second end of the second frame 232 is movably disposed on the second mounting base 22 along the height direction.

[0109] It is understandable that by setting the connecting bracket 23 as the first frame 231 and the second frame 232, the first frame 231 and the second frame 232 can be assembled in stages during the installation of the wind turbine tower 8. For example, the first frame 231 can be connected to the inner wall of the wind turbine tower 8 through the first mounting seat 21. When the wind turbine tower 8 is hoisted into place, that is, when the current wind turbine tower 8 is connected to the wind turbine tower 8 below, the first frame 231 can be connected to the second mounting seat 22 on the mast 1 through the second frame 232. This design is beneficial to improving the installation efficiency of the connecting bracket 23 and reducing the installation difficulty.

[0110] In practical applications, such as Figure 7 As shown, the first frame 231 is roughly trapezoidal, and the second frame 232 is roughly rectangular. The length of the first end of the first frame 231 is greater than the length of the second end. The first end of the first frame 231 has two first connection points, the second end of the first frame 231 has two second connection points, the first end of the second frame 232 has two third connection points, and the second end of the second frame 232 has two fourth connection points. Each of the two first connection points can be connected to the two first mounting seats 21 one-to-one via pins or other connecting parts. Each of the two second connection points can be connected to the two third connection points one-to-one via pins or other connecting parts. Both of the two third connection points are movably located on the second mounting seat 22 along the height direction. This design facilitates the sequential assembly of the first mounting seat 21, the first frame 231, and the second frame 232, and also improves the stability of the assembled structure in the connected state.

[0111] In some embodiments, such as Figure 7 As shown, along the radial direction of the wind turbine tower 8, the radial length of the second frame 232 is less than the radial length of the first frame 231.

[0112] Understandably, since the radial length of the second frame 232 is less than the radial length of the first frame 231, the size of the second frame 232 is smaller than the size of the first frame 231. When assembling the first frame 231 and the second frame 232 in stages, the relatively larger first frame 231 can be hoisted together with the wind turbine tower 8, while the relatively smaller second frame 232 can be hoisted separately. This not only has a clear division of labor and is convenient to operate, but also ensures the convenience of hoisting the second frame 232 in a relatively confined space.

[0113] In some embodiments, such as Figure 7 and Figure 8 As shown, the second mounting base 22 is provided with a hinge shaft 221, which extends along the height direction; the second end of the second frame 232 is provided with an adjusting rod 2321, the first end of the adjusting rod 2321 is adjustablely provided on the second frame 232 along the radial direction of the wind turbine tower 8, and the second end of the adjusting rod 2321 is rotatably sleeved on the outside of the hinge shaft 221 and can move along the hinge shaft 221.

[0114] Understandably, by rotatably fitting the second end of the adjusting rod 2321 onto the outside of the hinge shaft 221 and enabling it to move along the hinge shaft 221, it is possible to ensure that the entire connecting bracket 23 has a degree of freedom of rotation relative to the second mounting base 22 about the axis in the height direction, as well as a degree of freedom of movement relative to the second mounting base 22 in the height direction. This design can effectively prevent the mast 1 from twisting and deforming due to the tension and contraction of the wind turbine tower 8.

[0115] In practical applications, such as Figure 8 As shown, the second mounting base 22 has ear plates on the side facing the connecting bracket 23, and the hinge shaft 221 is inserted between the two ear plates along the height direction. The adjusting rod 2321 includes a bushing and a threaded rod. The bushing is sleeved on the peripheral wall of the hinge shaft 221 and can move along the hinge shaft 221. The first end of the threaded rod is connected to the bushing, and the second end of the threaded rod is threadedly connected to the threaded hole of the second frame 232. By rotating the threaded rod, the entire adjusting rod 2321 can be adjusted to move radially relative to the second frame 232 along the wind turbine tower 8, so as to adjust the relative position of the second mounting base 22 and the second frame 232.

[0116] Of course, the second end of the threaded rod can also be inserted into the through hole of the second frame 232, and a fixing nut can be installed on the threaded rod. The fixing nut abuts against the second frame 232 radially to achieve a reliable connection between the threaded rod and the second frame 232. In this way, when the bushing is fitted onto the peripheral wall of the hinge shaft 221, the relative position of the second mounting base 22 and the second frame 232 can be adjusted by adjusting the position of the fixing nut.

[0117] To further ensure the reliability of the connection between the threaded rod and the second frame 232, two fixing nuts can be provided, one fixing nut abutting against the side of the second frame 232 facing the bushing, and the other fixing nut abutting against the side of the second frame 232 away from the bushing.

[0118] In some embodiments, multiple support components 2 are provided, and the multiple support components 2 are arranged sequentially at intervals along the height direction of the mast 1, with a height difference of 10-30m between two adjacent support components 2.

[0119] It is understandable that by setting multiple support components 2 arranged along the height direction, it is convenient to apply horizontal constraints to the mast 1 at multiple positions along the height direction, which helps to shorten the slenderness ratio of the mast 1 and increase the longitudinal stability of the mast 1.

[0120] Since the height difference between two adjacent support components 2 is 10-30m, this arrangement ensures the longitudinal stability of the mast 1 without increasing the overall construction cost of the mast 1 system due to an excessive number of support components 2. It should be particularly noted that, compared to existing designs that require a large number of connectors (such as embedded parts or welded parts) to construct the ladder guide rails, this invention can stably install the mast 1 vertically within the wind turbine tower 8 at a lower construction cost.

[0121] It should be noted that the height difference between two adjacent support components 2 of the present invention corresponds to the number of layers of the wind turbine tower 8 assembled. For example, every 3-4 layers of wind turbine tower 8 are assembled, a support component 2 is set between the mast 1 and the next layer of wind turbine tower 8 assembled. The height difference between two adjacent support components 2 can be 10m, 15m, 20m, 25m, 30m and other suitable values, and is not specifically limited to this.

[0122] In the second aspect, such as Figure 1 As shown, this embodiment of the invention also provides a wind turbine generator set, including: a wind turbine generator, a wind turbine tower 8, and a wind power mast-type work platform system as described in any of the above embodiments; the mast 1 and the wind turbine tower 8 are respectively set on the tower foundation 9, the wind turbine tower 8 has multiple layers, and the multiple layers of wind turbine tower 8 are connected sequentially from bottom to top. The wind turbine tower 8 can be a concrete tower or a truss tower, and there is no specific limitation thereto. The wind turbine tower 8 is supported at the bottom of the wind turbine generator, and the wind power mast-type work platform system is set inside the wind turbine tower 8.

[0123] It is understood that since the wind turbine generator set includes a wind turbine mast-type work platform system, and the specific structure of the wind turbine mast-type work platform system refers to the above embodiments, the wind turbine generator set of this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiments, which will not be elaborated on one by one.

[0124] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
