Description

Technical Field

[0001] This utility model belongs to the field of wind power equipment maintenance technology, specifically a climbing frame for maintaining wind power equipment with safety protection. Background Technology

[0002] As a device that converts wind energy into electrical energy, wind power equipment requires regular maintenance after prolonged use. Since wind power equipment is usually installed at high locations, climbing frames are often used to provide a relatively stable working platform for maintenance personnel to safely reach the work site and reduce the risk of falls from heights, enabling them to better carry out equipment inspection and maintenance work.

[0003] The existing climbing frames used for wind power equipment maintenance are placed on the ground. When personnel climb onto the climbing frames, the bottom of the frames is prone to sliding on the ground due to pressure, which affects the stability of personnel climbing onto the climbing frames to maintain the wind power equipment. Therefore, improvements are needed. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a climbing frame for wind power equipment maintenance with safety protection, which solves the problem that existing climbing frames for wind power equipment maintenance are placed on the ground, and the bottom of the climbing frame is prone to sliding on the ground when personnel climb onto the climbing frame, thus affecting the stability of personnel climbing the climbing frame to maintain the wind power equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a climbing frame for the maintenance of wind power generation equipment with safety protection, comprising a climbing frame body, mounting grooves at the bottom of both ends of the climbing frame body, a rotating groove at the center of the mounting groove, symmetrical limiting grooves at the top of both sides of the mounting groove, a fixing nail slidably mounted inside the mounting groove, an end block fixedly mounted on the top of the fixing nail, a limiting slider symmetrically fixedly mounted on the surface of the end block, and the limiting slider slidably connected inside the limiting groove, an adjusting screw sleeve on the surface of the fixing nail, and the adjusting screw sleeve located inside the rotating groove, symmetrical storage grooves on both sides of the inner wall of the climbing frame body, a support frame rotatably mounted on the top of the storage groove, and an anti-slip bottom strip fixedly mounted on one end of each of the two sets of support frames.

[0006] As a further embodiment of this utility model: a connecting strip is rotatably installed at the center of the storage slot, a connecting groove is provided on the top of the support frame surface, and one end of the connecting strip is slidably connected to the inside of the connecting groove.

[0007] As a further embodiment of this utility model: support strips are symmetrically and fixedly installed on the top of the anti-slip bottom strip, and the top of the support strips is fixedly connected to the surface of the support frame.

[0008] As a further embodiment of this utility model: the anti-slip bottom strip is provided with mounting grooves at both ends, and the surface of one side of the anti-slip bottom strip is provided with movable sliding grooves at both ends, and the movable sliding grooves are connected to the mounting grooves, and a fixed insert rod is slidably installed inside the mounting grooves.

[0009] As a further embodiment of this utility model: the bottom of the storage slot is provided with a fixing hole, and one end of the fixing rod passes through the mounting slot and corresponds to the position of the fixing hole.

[0010] As a further embodiment of this utility model: a limiting plate is fixedly installed at one end of the fixed insertion rod inside the mounting groove, a fixing spring is provided on the surface of the fixed insertion rod on one side of the limiting plate, and a lever is fixedly installed at one end of the fixed insertion rod inside the mounting groove, and the lever corresponds to the position of the movable slide groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This climbing frame for wind power equipment maintenance, featuring safety protection, consists of a main frame, fixing nails, end blocks, limit sliders, and adjusting sleeves. After the main frame is unfolded and placed on the ground, rotating the adjusting sleeve causes it to rotate on the surface of the fixing nail. The end block at the top of the fixing nail slides inside the mounting groove, causing the limit slider on the surface of the end block to slide and lock into the corresponding limit groove, thus locking and limiting the fixing nail. This prevents the fixing nail from rotating synchronously with the adjusting sleeve inside the mounting groove until it is firmly planted on the ground, securing the main frame. This ensures that the main frame will not slip on the ground when personnel climb onto it, thereby improving the stability of personnel climbing the main frame to maintain the wind power equipment.

[0013] 2. This climbing frame for wind power equipment maintenance with safety protection is equipped with fixed insertion holes, support frames, fixed insertion rods, and fixed springs. Pushing and squeezing two sets of levers causes the fixed insertion rods to retract into the corresponding mounting slots, causing the fixed springs to deform on the surface of the fixed insertion rods. At the same time, it pushes the support frames into the corresponding storage slots until the fixed insertion rods are aligned with the fixed insertion holes. After releasing the levers, the fixed insertion rods are pushed out of the mounting slots by the rebound of the fixed springs, allowing them to insert into the corresponding fixed insertion holes. This secures the anti-slip bottom strip between the two sets of opposing storage slots, ensuring that the support frames are firmly secured inside the storage slots. When the climbing frame body is moved, the support frames will not sway or spread out at the bottom of the climbing frame body. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a climbing frame for the maintenance of wind power generation equipment with safety protection, including a climbing frame body 1. The bottom of both ends of the climbing frame body 1 is respectively provided with mounting grooves 2. The top of both sides of the mounting groove 2 are symmetrically provided with limiting grooves 4. The top of the fixing nail 5 is fixedly installed with an end block 6. The surface of the end block 6 is symmetrically fixedly installed with a limiting slider 7, and the limiting slider 7 is slidably connected to the inside of the limiting groove 4. By providing the limiting slider 7, when the fixing nail 5 slides inside the mounting groove 2, it drives the limiting slider 7 to slide inside the corresponding limiting groove 4, thereby clamping and fixing the fixing nail 5, ensuring that the fixing nail 5 will not rotate synchronously with the adjusting screw sleeve 8 inside the mounting groove 2.

[0021] A rotating groove 3 is provided in the center of the mounting groove 2. A fixing nail 5 is slidably installed inside the mounting groove 2. An adjusting screw sleeve 8 is provided on the surface of the fixing nail 5, and the adjusting screw sleeve 8 is located inside the rotating groove 3. Because of the adjusting screw sleeve 8, the fixing nail 5 can be rotated by turning the adjusting screw sleeve 8 on the surface of the fixing nail 5, so that the bottom end of the fixing nail 5 can extend out of the mounting groove 2 and be driven into the ground.

[0022] The inner wall of the climbing frame body 1 is symmetrically provided with storage slots 9 on both sides. A support frame 12 is rotatably installed on the top of the storage slot 9. A connecting strip 11 is rotatably installed in the center of the storage slot 9. A connecting groove 13 is provided on the top of the surface of the support frame 12. One end of the connecting strip 11 is slidably connected to the inside of the connecting groove 13. With the connecting strip 11 and the connecting groove 13, when the support frame 12 is rotated out from the inside of the storage slot 9 for unfolding, one end of the connecting strip 11 slides inside the connecting groove 13 until the connecting strip 11 is stuck at the bottom of the connecting groove 13, so that the connecting strip 11 is tightened between the climbing frame body 1 and the support frame 12, ensuring that the climbing frame body 1 and the support frame 12 can be stably placed on the ground at a certain angle.

[0023] Anti-slip bottom strips 14 are fixedly installed at one end of each of the two sets of support frames 12. Support strips 15 are symmetrically fixedly installed on the top of the anti-slip bottom strips 14, and the top of the support strips 15 are fixedly connected to the surface of the support frame 12. Because of the support strips 15, the support strips 15 are fixed between the anti-slip bottom strips 14 and the support frame 12, thereby supporting the support frame 12 and the anti-slip bottom strips 14 and ensuring that the support frame 12 and the anti-slip bottom strips 14 will not tilt when subjected to pressure.

[0024] The anti-slip bottom strip 14 has mounting grooves 16 at both ends, and movable sliding grooves 17 at both ends of one side surface of the anti-slip bottom strip 14, which are connected to the mounting grooves 16. A fixed insertion rod 18 is slidably installed inside the mounting groove 16. The bottom of the storage slot 9 has a fixed insertion hole 10, and one end of the fixed insertion rod 18 passes through the mounting groove 16 and corresponds to the position of the fixed insertion hole 10. By providing the fixed insertion rod 18 and the fixed insertion hole 10, the push lever 21 slides inside the movable sliding groove 17, which drives the fixed insertion rod 18 to slide inside the mounting groove 16, so that the fixed insertion rod 18 can extend out of the mounting groove 16 and insert into the corresponding fixed insertion hole 10, thereby clamping the anti-slip bottom strip 14 between the two sets of storage slots 9, and clamping the support frame 12 inside the storage slot 9.

[0025] A limiting plate 19 is fixedly installed at one end of the fixed insertion rod 18 inside the mounting groove 16. A fixing spring 20 is provided on the surface of the fixed insertion rod 18 on one side of the limiting plate 19. A lever 21 is fixedly installed at one end of the fixed insertion rod 18 inside the mounting groove 16, and the lever 21 corresponds to the position of the movable slide 17. Because of the fixed spring 20, the limiting plate 19 is pushed towards one end of the mounting groove 16 under the rebound action of the fixed spring 20, which drives the fixed insertion rod 18 to push out of the mounting groove 16 and insert into the corresponding fixed insertion hole 10.

[0026] The working principle of this utility model is as follows:

[0027] After rotating the support frame 12 to disengage from the storage slot 9, one end of the connecting strip 11 slides inside the corresponding connecting groove 13 until the support frame 12 and the climbing frame body 1 are tilted at a certain angle. The connecting strip 11 is then tightened between the support frame 12 and the climbing frame body 1. After placing the climbing frame body 1 on the ground, the adjusting screw sleeve 8 is rotated to allow the fixing nail 5 to slide down inside the installation groove 2 until the bottom end of the fixing nail 5 is embedded in the ground. The climbing frame body 1 is then secured to the ground. Personnel can then climb onto the climbing frame body 1 to inspect the wind power equipment. After maintenance, rotate the adjusting sleeve 8 in the reverse direction to retract the fixing pin 5 into the mounting groove 2. Then push the lever 21 to retract the fixing rod 18 into the mounting groove 16. At the same time, rotate the support frame 12 to engage the storage groove 9. After the fixing rod 18 and the fixing hole 10 are aligned, release the lever 21. Under the rebound of the fixing spring 20, the fixing rod 18 will be pushed out of the mounting groove 16 and inserted into the corresponding fixing hole 10, thus fixing the support frame 12 inside the storage groove 9 and reducing the space required for the climbing frame body 1 when it is not in use.
