Safety protection tools for climbing wind power towers

Abstract

This utility model belongs to the field of tower climbing safety technology, specifically relating to a safety protection tool for climbing wind power towers. It includes a straight ladder with a safety component. The safety component includes a guide rail, which is fixed to the outer wall of the ladder by bolts and nuts, and a locking element consisting of two sets of fixing blocks. This wind power tower climbing safety protection tool features a dual protection mechanism. In the event of a fall, firstly, the safety buckle applies tension to the metal ring, causing the hinge rod to rotate and compress the compression block, pushing the locking block against the outer wall of the guide rail. This increases friction and locks the block, preventing the worker from falling. Secondly, if the locking block fails, the safety buckle pulls the ring, causing the rotating block to rotate and the hook to become perpendicular to the horizontal plane. The hook then hooks onto the outer wall of the ladder support rod, preventing the worker from falling further. This dual protection significantly improves climbing safety.

Description

Technical Field

[0001] This utility model relates to the field of tower climbing safety technology, specifically a safety protection tool for climbing wind power towers. Background Technology

[0002] Tower climbing safety protection devices are a comprehensive protection system specifically designed to ensure the safety of personnel when climbing towers such as power towers, communication towers, and wind turbine towers. Its core function is to prevent personnel from being injured due to accidental falls, slips, or collisions.

[0003] Currently, most existing safety equipment relies on a single protective structure, such as a standard safety rope or a simple locking device. When critical components malfunction or fail, they cannot provide backup protection. If the safety rope breaks or the locking device loosens, and maintenance personnel accidentally fall during climbing, there is a lack of effective protection, making accidents difficult to prevent. Unlike newer safety equipment that provides dual protection, these devices have a low safety factor. Therefore, we propose a safety protection tool for climbing wind turbine towers. Utility Model Content

[0004] The main objective of this invention is to provide a safety protection tool for climbing wind power towers, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a safety protection tool for climbing wind power towers, including a straight ladder, on which a safety component is provided. The safety component includes:

[0006] The guide rail is fixed to the outer wall of the straight ladder by bolts and nuts;

[0007] The locking component consists of two sets of fixing blocks, namely, a first set of fixing blocks and a second set of fixing blocks. The two sets of fixing blocks are fixedly connected to the second set of fixing blocks by bolts and nuts.

[0008] Preferably, the first fixing block has a housing connected to its outer wall, and the housing is penetrated by a fixing rod and rotatably connected to the fixing rod.

[0009] Preferably, the fixing rod has a hook fixedly connected to one end and a rotating block fixedly connected to the other end.

[0010] Preferably, one end of the rotating block is connected to a tension spring, the end of the tension spring away from the rotating block is fixedly connected to the inner wall of the housing, and the other end of the rotating block is connected to a safety rope, the end of the safety rope being connected to a ring.

[0011] Preferably, the second fixing block has a locking block inside, and the outer wall of the locking block is connected to a guide rod and a pressing block. The guide rod passes through the second fixing block and is slidably connected to the second fixing block. The guide rod is elastically connected to the outer wall of the second fixing block by a spring.

[0014] Beneficial effects

[0015] This utility model provides a safety protection tool for climbing wind power generation towers. It has the following beneficial effects:

[0016] (1) The wind power tower climbing safety protection tool is designed with a dual protection mechanism. When the maintenance personnel unfortunately fall, on the one hand, the safety buckle applies a pulling force to the metal ring, causing the hinge rod to rotate and squeeze the squeezing block, pushing the locking block against the outer wall of the guide rail, thereby increasing the friction to lock and prevent the maintenance personnel from falling; on the other hand, if the locking block fails, the safety buckle pulls the ring to make the rotating block rotate, causing the hook to be perpendicular to the horizontal plane, and the hook will be hooked on the outer wall of the straight ladder support rod, preventing the maintenance personnel from continuing to fall. The dual protection greatly improves the climbing safety.

[0017] (2) The safety protection tool for climbing wind power towers has a guide rail for the safety component that is fixed to the outer wall of the straight ladder by bolts and nuts. The locking component consists of a fixing block one and a fixing block two, which are connected by bolts and nuts. During installation, simply insert the roller into the inner groove of the guide rail and tighten the nut to complete the fixation. The structure is stable and not easy to loosen. At the same time, this simple installation method facilitates quick installation and disassembly, and is convenient to operate in actual use, thus enhancing the practicality of the safety protection tool.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model proposes a safety protection tool for climbing wind power towers, including a straight ladder 1, on which safety components are provided.

[0029] In an embodiment of this utility model, in order to improve the safety of climbing the ladder 1, the safety component specifically includes a guide rail 2, which is fixed to the outer wall of the ladder 1 by bolts and nuts. The locking component 3 consists of two sets of fixing blocks 31 and fixing blocks 32. The two sets of fixing blocks 31 are fixedly connected to fixing blocks 32 by bolts and nuts. The fixing blocks 32 have a locking block 321 inside. The outer wall of the locking block 321 is connected to a guide rod 322 and a pressing block 324. The guide rod 322 passes through the fixing blocks 32 and is slidably connected to the fixing blocks 32. The guide rod 322 is elastically connected to the outer wall of the fixing blocks 32 by a spring 323. The fixing blocks 32 are connected to a shaft 325, which passes through a hinge rod 326 and is rotatably connected to the hinge rod 326. The end of the hinge rod 326 is connected to a metal ring 327.

[0030] Furthermore, a fixing block 31 is attached to a housing 312 on its outer wall. The housing 312 is penetrated by a fixing rod 313 and is rotatably connected to the fixing rod 313. A hook 314 is fixedly connected to one end of the fixing rod 313, and a rotating block 315 is fixedly connected to the other end of the fixing rod 313. A tension spring 316 is connected to one end of the rotating block 315. The end of the tension spring 316 away from the rotating block 315 is fixedly connected to the inner wall of the housing 312. A safety rope 317 is connected to the other end of the rotating block 315. A ring 318 is connected to the end of the safety rope 317. A roller 311 is provided on the fixing block 31.

[0031] In this utility model, during use, firstly, the rollers 311 on one set of fixing blocks 31 are inserted into the inner groove of the guide rail 2, then the nut is loosened, and then the rollers 311 on the other set of fixing blocks 31 are inserted into the inner groove on the other side of the guide rail 2. Then the nut is tightened to securely connect fixing blocks 31 and 32. Next, the safety buckle on the maintenance personnel is connected sequentially to the ring 318 and the metal ring 327. When the maintenance personnel unfortunately fall during climbing, at that instant, the safety buckle will connect to the metal ring... The safety buckle connected to 327 applies a pulling force to the hinge rod 326, causing the hinge rod 326 to rotate around the shaft 325. During this process, the hinge rod 326 will press the pressing block 324, causing the pressing block 324 to push the locking block 321 to move to the outer wall of the guide rail 2. At this time, the locking block 321 will be firmly pressed against the outer wall of the guide rail 2. By increasing the friction between the locking block 321 and the outer wall of the guide rail 2, the locking component 3 is locked, thereby preventing maintenance personnel from accidentally falling.

[0032] While the safety buckle pulls the metal ring 327, the ring 318 connected to the safety buckle applies a pulling force to the rotating block 315, causing the rotating block 315 to rotate. When the rotating block 315 rotates, the fixed rod 313, which is fixedly connected to the rotating block 315, will drive the hook 314 to rotate synchronously, making the hook 314 perpendicular to the horizontal plane. If the locking block 321 fails, the locking element 3 will move downward synchronously along the guide rail 2 with the maintenance personnel. During this downward movement, the hook 314 will be hooked on the outer wall of the support rod of the ladder 1, thereby preventing the maintenance personnel from falling further and improving their safety.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
