Description

Technical Field

[0001] This utility model relates to the field of maintenance basket technology, specifically a basket for wind turbine maintenance. Background Technology

[0002] A wind turbine is a device that converts wind energy into electrical energy. It mainly consists of blades, a generator, mechanical components, and electrical components. Based on the different rotating shafts, wind turbines are mainly divided into two categories: horizontal axis wind turbines and vertical axis wind turbines. Currently, horizontal axis wind turbines dominate the market. Wind turbines require regular maintenance during use, and maintenance baskets are needed to hoist maintenance personnel during the maintenance process.

[0003] According to a public notice (Announcement No.: CN213038827U), the above application includes a basket body and a hoisting bracket. The hoisting bracket includes an upper support rod, a lower support rod, a column, and a lifting ring. The upper support rod and the lower support rod are both vertically welded to the outside of the basket body. The column is welded to the outer ends of the upper support rod and the lower support rod, respectively. A lifting ring is welded to the top of the column and is connected to the wire rope lifting ring of the hoist.

[0004] However, in actual use, the aforementioned maintenance scaffolds are susceptible to swaying or even shaking due to complex wind conditions, especially during high-altitude operations. This not only affects the stability and safety of the workers but may also lead to inaccurate equipment positioning, increasing operational risks and construction difficulties. In extreme cases, there is even a risk of collision with the tower or failure of the operation. In view of this, we propose a scaffold for wind turbine maintenance. Utility Model Content

[0005] The purpose of this invention is to provide a suspended platform for wind turbine maintenance, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspended platform for wind turbine maintenance, comprising a platform body, a connecting frame fixedly connected to the side wall of the platform body, and a stabilizing component provided on the inner wall of the connecting frame, the stabilizing component comprising:

[0007] A horizontal guide rail is slidably connected to a slider, and the slider is fixedly connected to a vertical guide rail.

[0008] Slider 2, the inner wall of slider 2 is provided with a crossbar, and a disc is fixedly connected to the end face of the crossbar;

[0009] A movable rod, one end of which is fixedly connected to a suction cup, and the end of the movable rod away from the suction cup is hinged to a handle.

[0010] Preferably, the side wall of the suspended platform body is fixedly connected to the external hoisting rope, and the hoisting rope is fixedly connected to the hoisting winch, so as to realize the control of the position of the suspended platform body.

[0011] Preferably, the transverse guide rail is fixedly connected to the inner wall of the connecting frame, and the transverse guide rail is perpendicular to the vertical guide rail.

[0012] Preferably, the second slider is slidably connected to the vertical guide rail, and the cross-section of the crossbar is hexagonal. Adjusting the position of the vertical guide rail and the second slider adjusts the position of the suction cup.

[0013] Preferably, the movable rod is sleeved with the crossbar, the suction cup is movably connected to the disc, and the handle is movably connected to the end face of the crossbar.

[0014] Preferably, the second slider is inserted into the pull rod, and the bottom end of the pull rod is fixedly connected to an insert block, which is arranged in an isosceles trapezoidal shape.

[0015] Preferably, the side wall of the crossbar is provided with a positioning groove, which is inserted into the plug to fix the position of the crossbar 305.

[0016] Compared with the prior art, this utility model provides a suspended platform for wind turbine maintenance, which has the following advantages:

[0017] 1. This suspended platform for wind turbine maintenance uses a stabilizing component and suction cups to partially adhere the side wall of the platform to the wind turbine casing, forming a temporary fulcrum to suppress lateral swaying and improve the overall stability of the platform. This makes operation safer and more precise for maintenance personnel. The suction cup position is multi-directionally adjustable to adapt to different tower curvatures and installation locations, making it highly versatile and flexible. Pushing the handle end face to move the crossbar and disc toward the suction cup causes the disc to press against the suction cup, making the suction cup adhere more tightly to the outer wall of the wind turbine, improving the stability and firmness of the adhesion, and preventing the suction cup from loosening or falling off under wind or vibration.

[0018] 2. This suspended platform for wind turbine maintenance, through the set inserts and positioning slots, adjusts the distance between the suction cup and the wind turbine, and locks the relative position between the suspended platform body and the wind turbine, avoiding distance changes caused by shaking, wind, or work disturbances, thereby improving the stability of the suction cup support point and making the suspended platform body more stable and safer when working at height.

[0027] In one embodiment of this utility model, the horizontal guide rail 301 is fixedly connected to the inner wall of the connecting frame 2, the horizontal guide rail 301 is slidably connected to the slider 302, the slider 302 is fixedly connected to the vertical guide rail 303, and the horizontal guide rail 301 and the vertical guide rail 303 are perpendicular to each other.

[0028] The second slider 304 is slidably connected to the vertical guide rail 303. A crossbar 305 is slidably connected to the inner wall of the second slider 304. The crossbar 305 has a hexagonal cross section. Adjusting the position of the vertical guide rail 303 and the second slider 304 will adjust the position of the suction cup 308. A disc 306 is fixedly connected to the end face of the crossbar 305.

[0029] The movable rod 307 is sleeved with the crossbar 305. One end of the movable rod 307 is fixedly connected to a suction cup 308. The end of the movable rod 307 away from the suction cup 308 is hinged to a handle 309. The suction cup 308 is movably connected to the disc 306. The handle 309 is movably connected to the end face of the crossbar 305.

[0030] The side wall of the suspended platform body 1 is fixedly connected to the external hoisting rope, and the hoisting rope is fixedly connected to the winch of the crane, so as to realize the control of the position of the suspended platform body 1.

[0031] Slide slider 302 to move vertical guide rail 303 laterally along horizontal guide rail 301, adjusting the position of vertical guide rail 303. Then slide slider 304 to move vertical guide rail 303 longitudinally, adjusting the longitudinal position of suction cup 308. Then push handle 309 to make suction cup 308 adhere to the outer wall of wind turbine. Suction cup 308 partially adheres the side wall of the basket body 1 to the wind turbine casing, forming a temporary fulcrum, suppressing lateral sway, improving the overall stability of the basket, and making operation safer and more precise for maintenance personnel. The position of suction cup 308 is multi-directionally adjustable to adapt to different tower curvatures and installation locations, with strong versatility and flexible adjustment.

[0032] Rotating the handle 309, the distance between the end face of the handle 309 and the rotating shaft is greater than the distance between the side wall of the handle 309 and the rotating shaft, causing the end face of the handle 309 to push the crossbar 305 and the disc 306 toward the suction cup 308, thereby causing the disc 306 to squeeze the suction cup 308, making the suction cup 308 adhere more tightly to the outer wall of the wind turbine, improving the stability and firmness of the adsorption, and preventing the suction cup 308 from loosening or falling off under the action of wind or vibration.

[0033] In addition, the slider 304 is inserted into the pull rod 6, and the bottom end of the pull rod 6 is fixedly connected to the insert block 5. The side wall of the crossbar 305 is provided with a positioning groove 4, and the positioning groove 4 is inserted into the insert block 5. First, pull up the pull rod 6 so that the crossbar 305 can slide. The sliding crossbar 305 can adjust the distance between the suction cup 308 and the wind turbine. After rotating the handle 309 to make the disc 306 squeeze the suction cup 308, push the pull rod 6 and the insert block 5 downward so that the insert block 5 is inserted into the positioning groove 4. After the insert block 5 is inserted into the positioning groove 4, a rigid limiting structure is formed, locking the relative position between the basket body 1 and the wind turbine, avoiding distance changes caused by shaking, wind or operation disturbance, thereby improving the stability of the support point of the suction cup 308, making the basket body 1 more stable and safe when working at height.

[0034] In this utility model, during use, slide slider 302 to move vertical guide rail 303 laterally along horizontal guide rail 301 to adjust the position of vertical guide rail 303. Then slide slider 304 to move vertically along vertical guide rail 303 to adjust the longitudinal position of suction cup 308. Then push handle 309 to make suction cup 308 adhere to the outer wall of wind turbine. Suction cup 308 partially adheres the side wall of the basket body 1 to the wind turbine casing, forming a temporary fulcrum to suppress lateral swaying. Rotate handle 309 so that the distance between the end face of handle 309 and the rotation axis is greater than the distance between the side wall of handle 309 and the rotation axis. This causes the end face of handle 309 to push crossbar 305 and disc 306 toward suction cup 308, thereby causing disc 306 to squeeze suction cup 308, making suction cup 308 adhere more tightly to the outer wall of wind turbine, improving the stability and firmness of the adhesion.
