Description

Technical Field

[0001] This utility model belongs to the field of maintenance platform technology, specifically, it relates to a wind power generation tower maintenance platform. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. However, during daily use, wind turbine generators inevitably experience problems such as damage and aging, which usually require staff to use maintenance platforms to inspect and repair them. Chinese patent CN219950424U discloses a lifting device for maintaining wind power towers. The device moves to a designated position via a moving component, operates two sets of balancing and reinforcing components to balance and reinforce the load-bearing plate, and allows workers to enter the lifting platform and operate the scissor lift to raise the platform, thereby reducing the possibility of the load-bearing plate and scissor lift tipping over. Chinese Patent No. CN222846434U discloses a wind power tower maintenance platform, including a base, with casters installed at the four corners of the base, a mounting plate on the top of the base, a scissor lift on the top of the mounting plate, a lifting platform on the top of the scissor lift, an adjustment assembly between the mounting plate and the base, and a guardrail on the top of the lifting platform. In actual operation of wind turbine tower maintenance platforms, the lifting and lowering device needs to lift and lower maintenance personnel to a designated height to complete maintenance operations. To ensure personnel safety, the platform is usually equipped with guardrails for protection. However, existing guardrails are mostly fixedly installed and connected to the lifting and lowering device. Although this design can play a protective role during operation, it becomes an obstacle to transportation after the platform is used. Fixed guardrails will increase the overall height of the maintenance platform, which not only increases the space occupied by the platform during transportation, but may also cause transportation inconvenience due to exceeding the height limit, and may even require additional disassembly steps to meet the transportation conditions, causing trouble for subsequent transfer work. In view of this, this utility model is proposed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wind power tower maintenance platform, which solves the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A wind turbine tower maintenance platform, comprising: Mobile platform; A lifting platform, which is fixed to the upper side of the mobile platform; Four guardrail mechanisms are installed around the perimeter of the lifting platform. Each guardrail mechanism includes a positioning component, a tilting component, and a guardrail component. The positioning component is installed on the lifting platform. The tilting assembly includes two toothed plates and a rotating rod. The two toothed plates are fixed to the upper side of the moving platform, and the rotating rod is rotated and engaged on one side of the lifting platform by a torsion spring. The toothed plates and the rotating rod mesh with each other. The guardrail assembly includes a frame, within which multiple crossbars are fixed, and the frame is fixed to a rotating bar.

[0005] Optionally, the mobile platform includes a base plate with multiple casters fixed to the underside of the base plate, a lifting platform mounted on the upper side of the base plate, and a toothed plate fixed to the upper side of the mobile platform.

[0006] Optionally, the lifting platform includes a scissor mechanism and a standing platform. The scissor mechanism is installed between the standing platform and the base plate. Four grooves are provided on the periphery of the standing platform. Four rotating rods are respectively rotated and engaged in the four grooves by torsion springs. Four positioning components are installed on the standing platform.

[0007] Optionally, a slot is provided on one side of the groove, and four channels are provided on the lower side of the standing platform. The four channels are connected to the four slots respectively. A slot is provided on the outer side of the rotating rod. The positioning component includes an insert plate and an elastic telescopic rod. The insert plate is elastically and slidably fitted in the slot. The insert plate and the slot are engaged. A two-link rod is installed between the insert plate and the slot. The elastic telescopic rod is fixed on the upper side of the base plate and is engaged with the two-link rod.

[0008] Optionally, the two-bar linkage includes a first rod and a second rod, with the ends of the first rod and the second rod rotatably connected, the other end of the first rod rotatably connected to the insert plate, and the other end of the second rod rotatably connected to the inner wall of the slot, and the elastic telescopic rod cooperating with the second rod.

[0009] Optionally, the upper side of the standing platform is provided with four sliding grooves, which are connected to four slots respectively. A slider is fixed on the upper side of the insert plate, and the slider slides in the sliding groove.

[0010] Optionally, two toothed rings are fixed on the rotating rod, and the toothed rings mesh with the toothed plate.

[0011] Optionally, the crossbar is a telescopic rod structure, and both ends of the telescopic rod structure are threaded into the frame.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: 1. The mobile platform is equipped with multiple wheels on the underside of its base plate, allowing maintenance personnel to easily move the platform to the vicinity of the tower without manual handling, thus improving the efficiency of pre-maintenance preparation. At the same time, the electric wheel drive can further reduce operational hassles and adapt to different site movement needs. 2. Multiple electric outriggers are installed on the outer wall of the base plate, which can not only fix the position of the mobile platform, but also adjust the horizontal angle of the base plate by adjusting the length of the outriggers, so that the platform can adapt to uneven ground, expand the range of applicable scenarios, and ensure the stability of subsequent operations. 3. The lifting platform uses a scissor mechanism to connect the standing platform and the base plate. The scissor mechanism extends and retracts to achieve smooth lifting and lowering of the standing platform, meeting the maintenance needs of towers at different heights. During the lifting process, the toothed plate of the tilting component engages with the rotating rod, causing the guardrail component to tilt synchronously. The insert plate of the positioning component inserts into the slot of the rotating rod through elasticity to position and fix the guardrail component, forming a protective barrier. This fully meets the protection requirements of maintenance personnel, reduces the risk of personnel falling from the standing platform, and ensures lifting and operation safety. 4. The crossbars of the guardrail assembly adopt a telescopic bar structure and are threaded to the frame at both ends. During maintenance, it is not necessary to disassemble the entire guardrail. Simply rotate the crossbar to disconnect the threaded connection and retract it to expose the maintenance surface of the tower, simplifying the operation process while preserving the integrity of the protective structure. 5. The sliding groove of the standing platform is fitted with a slider that is fixed to the insert plate. The upper surface of the slider is flush with the standing platform to avoid the risk of tripping. When the equipment linkage fails, the maintenance personnel can manually pull the slider to drive the insert plate out of the slot of the rotating rod, and release the guardrail positioning in an emergency, thereby improving emergency safety and operational flexibility. 6. After maintenance, when the lifting platform descends to near the mobile platform, the elastic telescopic rod abuts against the second rod of the two-linkage mechanism. Through the two-linkage transmission, the insert plate is driven to exit the slot, releasing the rotating rod from its positioning position. The rotating rod re-engages with the toothed plate and rotates, causing the guardrail assembly to flip and retract, reducing the overall height of the platform, reducing the floor space occupied when not in use, facilitating transportation and storage, and reducing the cost of equipment idle management.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Please see Figure 1-5 As shown, this embodiment provides a wind power tower maintenance platform, including: Mobile platform 1; Lifting platform 2 is fixed to the upper side of mobile platform 1; Four guardrail mechanisms 3 are installed around the lifting platform 2. Each guardrail mechanism 3 includes a positioning component 4, a tilting component 5, and a guardrail component 6. The positioning component 4 is installed on the lifting platform 2. The tilting assembly 5 includes two toothed plates 501 and a rotating rod 502. The two toothed plates 501 are fixed on the upper side of the moving platform 1, and the rotating rod 502 is rotated and engaged on one side of the lifting platform 2 by a torsion spring. The toothed plates 501 and the rotating rod 502 mesh with each other. The guardrail assembly 6 includes a frame 601, with multiple crossbars 602 fixed inside the frame 601, and the frame 601 is fixed to the rotating bar 502.

[0019] Working principle: The mobile platform 1 allows maintenance personnel to move the entire maintenance platform to the vicinity of the wind turbine tower, improving the convenience and efficiency of maintenance; the lifting platform 2 can perform lifting and lowering actions on the mobile platform 1, thereby meeting the needs of maintenance operations at different heights; maintenance personnel can use the guardrail assembly 6 as a ladder, directly climb onto the lifting platform 2 with the help of the crossbar 602, and then start the lifting platform 2 to rise. During the lifting process of the lifting platform 2, since the toothed plate 501 of the flipping component 5 is fixed on the moving platform 1, and the rotating rod 502 is rotated and engaged with the toothed plate 501 on one side of the lifting platform 2 through the torsion spring, the lifting action will drive the rotating rod 502 to rotate relative to the toothed plate 501, thereby allowing the frame 601 and the crossbar 602 of the guardrail component 6 fixed on the rotating rod 502 to flip. At the same time, the positioning component 4 can position the rotating rod 502 to ensure that the guardrail component 6 remains fixed after it is flipped, thereby protecting the maintenance personnel on the lifting platform 2; when the lifting platform 2 rises to the maintenance position of the tower, the maintenance personnel can carry out maintenance work on the tower. After maintenance is completed, maintenance personnel lower the lifting platform 2. When the lifting platform 2 descends to the upper side near the mobile platform 1, the positioning component 4 releases the positioning of the rotating rod 502, and the rotating rod 502 re-engages with the toothed plate 501, causing the rotating rod 502 to rotate. When the rotating rod 502 rotates, it will cause the frame 601 of the guardrail component 6 to flip, removing the protection for maintenance personnel. Moreover, the flipped-down guardrail component 6 can reduce the overall height of the maintenance platform, reduce the floor space occupied by the maintenance platform when not in use, and make the maintenance platform easier to transport. At this time, maintenance personnel can climb down the lifting platform 2 through the crossbar 602 inside the frame 601 and successfully complete the maintenance work on the tower.

[0020] like Figure 1-3 As shown: The mobile platform 1 in this embodiment includes a base plate 101, a plurality of moving wheels 102 are fixed on the lower side of the base plate 101, the lifting platform 2 is installed on the upper side of the base plate 101, and the toothed plate 501 is fixed on the upper side of the mobile platform 1.

[0021] Thanks to the rolling characteristics of the casters 102, maintenance personnel can easily push the entire platform, conveniently moving the entire maintenance platform to the vicinity of the wind turbine tower without requiring a large amount of manpower for transportation, thus improving the convenience and efficiency of pre-maintenance preparation. Meanwhile, the lifting platform 2 is installed on the upper side of the base plate 101, providing a stable bearing foundation for subsequent lifting operations. Among them, the movable wheel 102 adopts the existing omnidirectional wheel, and the omnidirectional wheel is equipped with a brake to fix the position of the omnidirectional wheel; in addition, an electric wheel can be installed on the underside of the base plate 101. Maintenance personnel only need to power the electric wheel to control the movement of the maintenance platform, which reduces the operation trouble when moving the maintenance platform.

[0022] In this embodiment, multiple electric outriggers are installed on the outer periphery of the base plate 101. When the mobile platform 1 moves to the vicinity of the tower, the position of the mobile platform 1 can be fixed by the electric outriggers. Moreover, maintenance personnel can adjust the horizontal angle of the base plate 101 by adjusting the length of the multiple electric outriggers, so that the base plate 101 can adapt to uneven ground.

[0023] like Figure 1-3 As shown: The lifting platform 2 in this embodiment includes a scissor mechanism 201 and a standing platform 202. The scissor mechanism 201 is installed between the standing platform 202 and the base plate 101. Four grooves 203 are formed on the periphery of the standing platform 202. Four rotating rods 502 are respectively rotatably engaged in the four grooves 203 by torsion springs. Four positioning components 4 are installed on the standing platform 202. The lifting platform 2 is a scissor lift platform in the prior art. In this embodiment, a slot 204 is formed on one side of the groove 203. Four channels 205 are formed on the lower side of the standing platform 202. The four channels 205 are respectively connected to the four slots 204. A slot 503 is formed on the outer side of the rotating rod 502. The positioning component 4 includes an insert plate 401 and an elastic telescopic rod 402. 1. An insert plate 401 is elastically and slidably fitted within the slot 204, which engages with the slot 503. A two-link rod 403 is installed between the insert plate 401 and the slot 204. An elastic telescopic rod 402 is fixed to the upper side of the base plate 101 and engages with the two-link rod 403. In this embodiment, the two-link rod 403 includes a first rod body 404 and a second rod body 405. The ends of the first rod body 404 and the second rod body 405 are rotatably connected. The other end of the first rod body 404 is rotatably connected to the insert plate 401, and the other end of the second rod body 405 is rotatably connected to the inner sidewall of the slot 204. The elastic telescopic rod 402 engages with the second rod body 405. In this embodiment, two toothed rings 504 are fixed on the rotating rod 502, and the toothed rings 504 mesh with the toothed plate 501.

[0024] The scissor mechanism 201 extends and retracts between the standing platform 202 and the base plate 101, enabling the standing platform 202 to rise and fall smoothly, meeting the maintenance needs at different heights. The four grooves 203 on the periphery of the standing platform 202 provide installation space for the rotating rod 502. The rotating rod 502 rotates and engages with the grooves 203 through a torsion spring, ensuring both the flexibility of the rotation and providing initial support for the guardrail assembly 6 to be rotated onto the upper side of the standing platform 202. As the standing platform 202 rises, the second rod 405 in the two-link 403 gradually disengages from the elastic telescopic rod 402 as the height changes. At this time, the insert plate 401 slides out of the groove 205 through elastic force and inserts into the rotating rod 502 after initial support, thus fixing the rotating rod 502 and fixing the guardrail assembly 6, ensuring stable protection of the guardrail assembly 6 after flipping. When the standing platform 202 descends to near the base plate 101 and continues to descend, the elastic telescopic rod 402 fixed on the base plate 101 will abut against the second rod 405 of the two-link 403; as the standing platform 202 continues to descend, the elastic telescopic rod 402 is gradually compressed; after the second rod 405 is subjected to the abutment force, through the transmission action of the two-link 403, that is, the first rod 404 rotates synchronously with the second rod 405, driving the insert plate 401 to slide along the slot 204 and exit the slot 503 of the rotating rod 502, thereby releasing the positioning constraint on the rotating rod 502; At the same time, as the standing platform 202 descends, the rotating rod 502 will re-engage with the toothed plate 501 fixed on the mobile platform 1. Under the engagement, the rotating rod 502 will rotate around itself, thereby driving the guardrail assembly 6 to rotate synchronously, and finally releasing the guardrail assembly 6 from the protective state of the maintenance personnel on the standing platform 202.

[0025] like Figure 2-5 As shown: The upper side of the standing platform 202 in this embodiment is provided with four sliding grooves 206, which are respectively connected to four slots 204. A slider 406 is fixed on the upper side of the insert plate 401, and the slider 406 slides in the sliding groove 206.

[0026] The upper surface of the slider 406 is flush with the upper surface of the standing platform 202, which can prevent the slider 406 from protruding and causing obstruction, reduce the impact on the operation of maintenance personnel on the standing platform 202, and ensure the safety of personnel activities. In addition, slider 406 also has an emergency operation function: when maintenance personnel encounter special situations, such as equipment linkage failure, and need to urgently release the protective state of guardrail component 6, they can directly pull slider 406 manually to make slider 406 slide along slide groove 206; during the sliding process of slider 406, it will simultaneously drive insert plate 401 to move, causing insert plate 401 to exit the slot 503 of rotating rod 502, thereby quickly releasing the positioning of rotating rod 502, and finally realizing the emergency release of the protective state of guardrail component 6, further improving the safety and emergency flexibility of platform use.

[0027] In this embodiment, the crossbar 602 is a telescopic rod structure, and both ends of the telescopic rod structure are threaded into the frame 601.

[0028] Among them, the height of the frame 601 of the guardrail component 6 is set to 1-2m, with a preferred height of 2m; this height design can fully cover the body protection needs of maintenance personnel, forming a reliable safety barrier and reducing the risk of maintenance personnel falling when working on the standing platform 202. In addition, for tower surface maintenance scenarios, since the crossbar 602 adopts a telescopic rod structure and its two ends are threaded to the frame 601, maintenance personnel can manually rotate one end of the telescopic rod structure to disconnect it from the frame 601; at this time, the telescopic rod structure can retract freely, thereby exposing the surface of the tower that needs maintenance, without disassembling the entire guardrail assembly 6, which simplifies the operation process and ensures the protective integrity of the standing platform 202 during maintenance.

[0029] It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.

[0030] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
