Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wind power maintenance technology, and in particular relates to a safety ladder for wind power equipment maintenance. Background Technology
[0002] Safety ladders used for wind power equipment maintenance are important facilities to ensure the safety of maintenance personnel working at heights. Their design must take into account structural stability, corrosion resistance, slip resistance, fall protection, and compliance.
[0003] Traditional safety ladders typically require workers to carry hooks to attach to the ladder to prevent falls. However, this method requires workers to frequently adjust the position of the hooks, which not only reduces work efficiency but also increases the number of steps involved, making the climbing process cumbersome. Utility Model Content
[0004] The purpose of this utility model is to provide a safety ladder for wind power equipment maintenance. By setting up an anti-fall component, specifically, when workers need to climb the ladder, they hang hooks on the hanging rings. During the climbing process, the entire anti-fall component slides on the strip plate, eliminating the need for workers to frequently change the position of the hooks. In the event of a fall, gravity will generate a strong pulling force, pulling the slider and the pressure plate. The second protrusion on the pressure plate will cooperate with the first protrusion on the strip plate to quickly stop the fall. Furthermore, the gravity generated by the fall will pull the pressure plate tighter and tighter, thereby preventing a fall. This solves the problem of traditional ladders where workers need to frequently adjust the position of the hooks during climbing, which not only reduces the efficiency of climbing but also increases the number of steps and makes the climbing process cumbersome.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a safety ladder for wind power equipment maintenance, comprising a wind tower, wherein a plurality of supports are fixedly connected to the inner wall of the wind tower, and a fixing plate is welded between every two supports; and further comprising: A climbing mechanism, which is mounted on a support frame, is used by workers to climb the wind tower, and includes a ladder installed on the front of the support frame; And an anti-fall-off mechanism, which is installed on the back of the ladder and is used to restrict the ladder after installation; The anti-fall mechanism on the back of the ladder restricts the ladder by cooperating with the fixing plate. Several mounting blocks are fixedly connected to the left and right sides of the ladder, and the ladder is fixed to the bracket by mounting bolts on the mounting blocks.
[0006] Furthermore, a strip plate is fixedly connected to the right side of the ladder, and the climbing mechanism also includes a fall protection component installed on the strip plate, which is used to protect workers when climbing; the strip plate is installed on the ladder by welding, which can maintain sufficient support; A limiting block is provided on the front of the strip plate. The limiting block is used to limit the fall arrestor. A limiting frame is fixedly connected to the inner side of the limiting block. Two slide rails are fixedly connected to the front of the strip plate. A sliding groove is opened inside the strip plate. Several protruding teeth are fixedly connected to the back of the strip plate. The slide rails and protruding teeth are integrally formed with the strip plate. The limiting block has two adapter slots on the side facing the slide rail, and the limiting block is slidably connected to the slide rail through the two adapter slots.
[0007] Furthermore, the anti-fall component includes an extrusion plate disposed on the back of the strip plate, a slider fixedly connected to the front of the extrusion plate, a hanging ring fixedly connected to the front of the slider, and a plurality of protruding teeth fixedly connected to the side of the extrusion plate facing the strip plate. The slider is slidably connected inside the groove. The slider is rectangular in shape, which can maintain stability during sliding. When no fall occurs, the extrusion plate is away from the strip plate, thus allowing the slider to slide smoothly in the groove. The slider slides through the limiting block and extends to the front of the limiting block. The slider has a hollow interior, and the limiting frame is slidably connected inside the slider.
[0008] Furthermore, an inner rod is fixedly connected to the inner wall of the slider, and a spring is sleeved on the outer side of the inner rod. Limiting grooves are opened on the left and right sides of the slider, and the two ends of the limiting frame are slidably connected to the inner wall of the limiting groove. The limiting frame is used to connect the limiting block and the slider, and the cooperation between the extrusion plate and the limiting frame when the extrusion plate is pulled can smoothly extrude the spring. The back of the inner rod and the back of the spring are both fixedly connected to the extrusion plate, and the front of the spring is fixedly connected to the surface of the limiting frame. The spring uses its elasticity to push the extrusion plate away from the strip plate.
[0009] Furthermore, the inner rod slides through the limiting frame, the limiting block is used to limit the movement of the slider, and the hanging ring is used to connect to the hook on the worker's body.
[0010] Furthermore, the anti-fall mechanism includes several connecting plates fixedly connected to the back of the ladder. A plug is fixedly connected to the back of the connecting plate, a plug rod is inserted inside the plug, and a limit plate is fixedly connected to the top of the plug rod. The connecting plate and the plug are integrally formed. After the plug is inserted into the fixed plate, it can position the ladder during installation. The fixing plate has a slot that matches the insert block. The insert block is inserted into the slot on the fixing plate, and the insert rod is inserted into the insert block to restrict it.
[0011] Furthermore, after the insertion rod is inserted into the insertion block, the limiting plate will limit the insertion rod, and after the insertion block is connected to the fixing plate, the mounting block will be aligned with the hole on the bracket.
[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a fall protection component. Specifically, when workers need to climb a ladder, they hang hooks on the hanging rings. During the climb, the entire fall protection component slides on the strip plate, eliminating the need for workers to frequently change the position of the hooks. In the event of a fall, gravity generates a strong pulling force, pulling the slider and the extrusion plate. The second protrusion on the extrusion plate engages with the first protrusion on the strip plate to quickly stop the fall. Furthermore, the gravity generated by the fall will tighten the extrusion plate further, thus preventing a fall.
[0013] 2. This utility model has an anti-fall-off mechanism. Specifically, the ladder is connected to the fixing plate by inserting a block on the back connecting plate. The ladder is then connected to the bracket. After the block is inserted into the fixing plate, the rod is inserted into the block, thereby restricting the ladder to the bracket. This effectively prevents the ladder from falling off. Even if the bolts used for installation come loose, the ladder will not fall off.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-7 As shown, this utility model is a safety ladder for wind power equipment maintenance, including a wind tower 1, with several supports 11 fixedly connected to the inner wall of the wind tower 1, and a fixing plate 12 welded between every two supports 11, and also including: Climbing mechanism 2 is mounted on support 11 and is used by staff to climb wind tower 1. Climbing mechanism 2 includes a ladder 21 installed on the front of support 11. And an anti-fall mechanism 3, which is installed on the back of the ladder 21 and is used to restrict the ladder 21 after installation. Among them, the anti-fall mechanism 3 on the back of the ladder 21 restricts the ladder 21 by cooperating with the fixing plate 12. Several mounting blocks 214 are fixedly connected to the left and right sides of the ladder 21. The ladder 21 is fixed to the bracket 11 by mounting bolts on the mounting blocks 214.
[0020] A strip plate 211 is fixedly connected to the right side of the ladder 21. The climbing mechanism 2 also includes a fall protection component 22 installed on the strip plate 211. The fall protection component 22 is used to protect workers when they climb. Limiting block 23 is set on the front of strip plate 211. Limiting block 23 is used to limit the fall arrestor 22. Limiting bracket 231 is fixedly connected to the inner side of limiting block 23. Two slide rails 212 are fixedly connected to the front of strip plate 211. Slide groove 213 is opened inside strip plate 211. Several protruding teeth 215 are fixedly connected to the back of strip plate 211. The limiting block 23 has two adapter slots on the side facing the slide rail 212, and the limiting block 23 is slidably connected to the slide rail 212 through the two adapter slots.
[0021] The fall arrestor 22 includes a compression plate 221 disposed on the back of the strip plate 211. A slider 222 is fixedly connected to the front of the compression plate 221, and a hanging ring 223 is fixedly connected to the front of the slider 222. Several protruding teeth 226 are fixedly connected to the side of the compression plate 221 facing the strip plate 211. The slider 222 is slidably connected inside the slide groove 213. When the worker needs to climb the ladder 21, the hook is hung on the hanging ring 223. During the climbing process, the fall arrestor 22 slides on the strip plate 211 as a whole, without the need for the worker to frequently change the position of the hook. When a fall occurs, a strong pulling force will be generated by gravity, pulling the slider 222 and the compression plate 221. The protruding teeth 226 on the compression plate 221 cooperate with the protruding teeth 215 on the strip plate 211 to quickly stop the fall. Furthermore, the gravity generated by the fall will pull the compression plate 221 tighter and tighter, thereby preventing a fall. The slider 222 slides through the limiting block 23 and extends to the front of the limiting block 23. The inside of the slider 222 is hollow, and the limiting frame 231 is slidably connected inside the slider 222.
[0022] An inner rod 224 is fixedly connected to the inner wall of the slider 222. A spring 225 is sleeved on the outer side of the inner rod 224. Limiting grooves 227 are opened on the left and right sides of the slider 222. The two ends of the limiting frame 231 are slidably connected to the inner wall of the limiting groove 227. The back of the inner rod 224 and the back of the spring 225 are both fixedly connected to the extrusion plate 221, and the front of the spring 225 is fixedly connected to the surface of the limit frame 231. The spring 225 uses its elasticity to push the extrusion plate 221 away from the strip plate 211.
[0023] The inner rod 224 slides through the limiting frame 231, the limiting block 23 is used to limit the movement of the slider 222, and the hanging ring 223 is used to connect the hook on the worker's body.
[0024] The anti-fall mechanism 3 includes several connecting plates 31 fixedly connected to the back of the ladder 21. A plug block 32 is fixedly connected to the back of the connecting plate 31. A plug rod 33 is inserted into the plug block 32. A limit plate 34 is fixedly connected to the top of the plug rod 33. The ladder 21 is connected to the fixed plate 12 through the plug block 32 on the back connecting plate 31, and the ladder 21 is connected to the bracket 11. When the plug block 32 is inserted into the fixed plate 12, the plug rod 33 is inserted into the plug block 32, thereby restricting the ladder 21 to the bracket. This can effectively prevent the ladder 21 from falling off. Even if the bolts used for installation come loose, the ladder 21 will not fall off. The fixing plate 12 has a slot that matches the insertion block 32. The insertion block 32 is inserted into the slot on the fixing plate 12, and the insertion rod 33 is inserted into the insertion block 32 to restrict the insertion block 32.
[0025] After the insertion rod 33 is inserted into the insertion block 32, the limiting plate 34 will limit the insertion rod 33, and after the insertion block 32 is connected to the fixing plate 12, the mounting block 214 will be aligned with the hole on the bracket 11.
[0026] One specific application of this embodiment is: In use, the ladder 21 is connected to the fixing plate 12 via the plug 32 on the back connecting plate 31, and the ladder 21 is then connected to the bracket 11. After the plug 32 is inserted into the fixing plate 12, the plug rod 33 is inserted into the plug 32. The limiting plate 34 is used to limit the plug rod 33. At this time, the mounting block 214 will correspond to the bracket 11. By installing bolts on the mounting block 214 and connecting it to the bracket 11, the ladder 21 can be fixed to the bracket 11. The plug rod 33 limits the plug 32, so the ladder 21 will not fall off after installation. When workers need to climb ladder 21, they attach the hook to the hanging ring 223 and then climb upwards. The hook, through the hanging ring 223, drives the entire anti-fall component 22 to slide on the strip plate 211. At this time, the limit block 23 slides on the two slide rails 212, and the slider 222 slides within the slide groove 213. Because the compression plate 221 is pushed away from the strip plate 211 by the elastic force of the spring 225, the slider 222 can slide smoothly within the slide groove 213. This method does not require workers to frequently change the position of the hook, allowing workers to continuously climb upwards until they reach the top. In the event of an accident and a worker falls, the resulting gravity will pull the hook to the hanging ring 223, at which point the slider 222 will be... Pull together, causing the extrusion plate 221 to move toward the strip plate 211, and the slider 222 slides on the limit frame 231 through the limit groove 227. At the same time, the inner rod 224 slides on the limit frame 231, and the extrusion plate 221 will squeeze the spring 225. When the second tooth 226 on the extrusion plate 221 contacts the first tooth 215 on the strip plate 211, the friction will stop the extrusion plate 221 and the slider 222. The gravity generated by the fall will pull the extrusion plate 221 tighter and tighter, thus preventing the fall. This structure responds quickly and can quickly pull the extrusion plate 221 to achieve the braking effect. Finally, the operator adjusts the state, and the slider 222 is no longer pulled. At this time, the extrusion plate 221 is returned to its original position by the elastic force of the spring 225.
