Description

Technical Field

[0001] This application relates to the field of safety equipment technology, specifically a fall prevention device for climbing power concrete poles. Background Technology

[0002] With the rapid development of technology, electricity has become widespread all over the world. Power transmission poles and high-voltage towers are ubiquitous. They not only serve as carriers of current, but also provide good leakage protection through insulation and grounding. However, the installation and fixing of wires on power concrete poles, as well as the routine maintenance, repair, or replacement of wires on these poles, can only be done manually by climbing the concrete poles.

[0003] Generally, power workers use foot slings to climb concrete poles, connecting themselves to the pole with only a single rope. However, if the connection between the rope and the pole is too tight, it increases the worker's burden while if the connection is too loose, it will not prevent falls, creating a safety hazard. Therefore, this method has certain shortcomings.

[0004] Therefore, this application provides a fall prevention device for climbing power concrete poles to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a fall protection device for climbing electric concrete poles, aiming to solve the problems of poor fall protection performance of existing climbing equipment mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a fall prevention device for climbing a cement pole, comprising a collar fitted onto the cement pole for use with foot pedals and a waist rope, and a cushion fall prevention mechanism movably mounted on the collar for supporting the human body.

[0007] The cushion anti-fall mechanism includes a connecting block fixedly installed on a collar. The connecting block has an inclined insertion hole. A support column is fixedly installed on the connecting block at the insertion hole, with the axial extension direction of the insertion hole being aligned with that of the insertion hole. A spring cavity is opened on the support column, with the axial extension direction of the insertion hole being aligned with that of the insertion hole. A spring rod is elastically installed in the spring cavity. One end of the spring rod extends into the insertion hole and is fixedly installed with a connecting rod that matches the insertion hole. An anti-slip plate adapted to a concrete pole is installed on the connecting rod. The surface of the anti-slip plate is frosted. The end of the spring rod away from the connecting rod extends outside the support column and is fixedly installed with a cushion. A strap assembly is fixedly installed on the cushion. In this way, when the user is climbing upwards and encounters instability, they can sit directly on the cushion. The cushion, under the weight of the body, presses down on the spring bar, which in turn presses down on the connecting rod. The connecting rod then moves the anti-slip plate diagonally, attaching it to the concrete pole. Because the anti-slip plate has a frosted finish, it further increases the friction between the anti-slip plate and the surface of the concrete pole. This friction helps to lock the anti-slip plate in place, providing stable support and preventing falls, thus further improving safety. Only when the user climbs upwards again and leaves the cushion can the anti-slip plate detach from the concrete pole and move.

[0008] Preferably, for ease of operation, the minimum distance between the end of the support column near the seat cushion and the central axis of the cement pole is set to 'a', and the minimum distance between the end of the support column near the anti-slip plate and the central axis of the cement pole is set to 'b', where 'a' is greater than 'b', so as to quickly contact the cement pole and complete the locking.

[0009] Preferably, to reduce operational difficulty, the diameter of the spring cavity is larger than the diameter of the insertion hole, the diameter of the spring rod is larger than the diameter of the connecting rod, and a spring is sleeved on the connecting rod. The two ends of the spring abut against the spring rod and the connecting block, respectively. Thus, without manual operation by workers, it can continue to move on the cement pole, which is convenient and quick.

[0010] Preferably, in order to complete the connection with the human body, the strap assembly includes a connecting buckle fixedly installed on the seat cushion, a traction rope fixedly installed on the connecting buckle, and a loop-shaped strap fixedly installed on the end of the traction rope away from the connecting buckle. Velcro is fixedly installed on the strap for easy connection with the human body and convenient operation.

[0011] Preferably, in order to install the anti-slip plate, a sleeve block is fixedly installed on the outer side wall of the anti-slip plate. The sleeve block has a sleeve hole that matches the connecting rod. The sleeve block is sleeved on the connecting rod. The sleeve block is provided with a first fastening bolt that passes through the sleeve hole and the connecting rod, which facilitates disassembly and assembly, and makes it easy to store, carry and maintain.

[0012] Preferably, for installing the collar, the collar includes a semi-circular fixed frame that is fixedly connected to the connecting block. Two symmetrically distributed quarter-circle sockets are hinged to both ends of the fixed frame. A fixed block is fixedly installed on the end of each socket away from the fixed frame. A second fastening bolt is provided through the fixed block, which completes the quick and convenient installation of the collar and the cement pole.

[0013] Preferably, to facilitate the sliding of the ring, the inner sidewalls of the fixing frame and the connecting frame are evenly provided with a number of ball grooves arranged in a circular array, and the ball grooves are rolled with balls to reduce friction and prevent jamming.

[0014] This fall arrest device works as follows: when a user is climbing upwards and becomes unstable, they can sit directly on the cushion. The cushion, under the weight of the user's body, presses down on the spring bar, which in turn presses down on the connecting rod. The connecting rod then moves the anti-slip plate diagonally, attaching it to the concrete pole. Because the anti-slip plate has a frosted finish, it further increases the friction between the anti-slip plate and the concrete pole surface, thereby securing the anti-slip plate through friction and providing stable support to the user to prevent falls, further improving safety. Only when the user climbs upwards again and leaves the cushion can the anti-slip plate detach from the concrete pole and move freely.

[0015] This fall arrestor device involves rotating and unfolding two connecting frames from both ends of the fixed frame, then fitting them onto the concrete pole. The two connecting frames are then rotated again to merge, and finally the two fixing blocks are secured with the second fastening bolt, completing the quick and convenient installation of the collar onto the concrete pole.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Example 1

[0025] This embodiment provides a fall prevention device for climbing power concrete poles, such as... Figure 1-5 As shown, the fall arrest device includes a collar 1, which is fitted onto a concrete pole and used in conjunction with foot pedals and a waist rope, and a cushion fall arrest mechanism 2, which is movably mounted on the collar 1 to support the human body.

[0026] The cushion anti-fall mechanism 2 includes a connecting block 21 fixedly installed on the collar 1. The connecting block 21 has an inclined insertion hole 22. A support column 23 is fixedly installed on the connecting block 21 in the insertion hole 22, which is aligned with the axial extension direction of the insertion hole 22. The support column 23 has a spring cavity 24 aligned with the axial extension direction of the insertion hole 22. A spring rod 25 is elastically installed in the spring cavity 24. One end of the spring rod 25 extends into the insertion hole 22 and is fixedly installed with a connecting rod 26 that is compatible with the insertion hole 22. An anti-slip plate 27 that is compatible with the cement pole is installed on the connecting rod 26. The surface of the anti-slip plate 27 is frosted. The end of the spring rod 25 away from the connecting rod 26 extends out of the support column 23 and is fixedly installed with a cushion 28. A strap assembly 29 is fixedly installed on the cushion 28.

[0027] When in use, put the ring 1 on the cement pole, with the seat 28 facing upwards, and tie the seat 28 to the user's waist using the strap assembly 29 to complete the connection between the human body and the seat anti-fall mechanism 2. Then install the waist belt and foot pedals to connect with the cement pole for climbing.

[0028] Understandably, if instability occurs while the user is climbing upwards, they can sit directly on the cushion 28. The cushion 28 is pressed down by the user's body weight, which in turn presses down on the spring rod 25. The spring rod 25 then presses down on the connecting rod 26, which in turn moves the anti-slip plate 27 diagonally, attaching it to the concrete pole. Because the anti-slip plate 27 has a frosted finish, the friction between the anti-slip plate 27 and the surface of the concrete pole is further increased. This friction helps to lock the anti-slip plate 27 in place, providing stable support and preventing falls, thus further improving safety. Only when the user climbs upwards again and leaves the cushion 28 can the anti-slip plate 27 detach from the concrete pole and move.

[0029] It should be noted that, in order to ensure that the direction of gravity of the cushion 28 is not consistent with the axis of the support column 23 when it is pressed down by the body weight, so that the spring rod 25 does not slide smoothly in the spring cavity 24, the inner wall of the spring cavity 24 and the spring rod 25 can be smoothed during the manufacturing of the equipment, and the spring rod 25 can be made to slide smoothly in the spring cavity 24 by applying lubricating oil.

[0030] Specifically, the minimum distance between the end of the support column 23 near the seat cushion 28 and the central axis of the cement pole is set as a, and the minimum distance between the end of the support column 23 near the anti-slip plate 27 and the central axis of the cement pole is set as b, where a is greater than b.

[0031] When in use, the gradually varying spacing design makes the support column 23 tilted, so that there is enough space between the seat 28 and the cement pole for workers to operate, and reduces the distance between the anti-slip plate 27 and the cement pole, so as to quickly contact the cement pole to complete the locking.

[0032] More specifically, the diameter of the spring cavity 24 is larger than the diameter of the insertion hole 22, the diameter of the spring rod 25 is larger than the diameter of the connecting rod 26, and a spring 210 is sleeved on the connecting rod 26, with the two ends of the spring 210 abutting against the spring rod 25 and the connecting block 21 respectively.

[0033] When in use, the spring 210 is compressed when the spring rod 25 moves downward under gravity. When the spring rod 25 loses pressure, the spring 210 will automatically rebound and push the spring rod 25 upward, thereby causing the anti-slip plate 27 to automatically fall off the outer wall of the cement pole. Thus, without the need for manual operation by workers, it is convenient and quick to continue moving on the cement pole.

[0034] Furthermore, the strap assembly 29 includes a connecting buckle 291 fixedly mounted on the seat cushion 28, a traction rope 292 fixedly mounted on the connecting buckle 291, a loop-shaped strap 293 fixedly mounted on the end of the traction rope 292 away from the connecting buckle 291, and a Velcro strap 294 fixedly mounted on the strap 293.

[0035] When in use, the traction rope 292 is threaded onto the connecting buckle 291 for fixation, and the strap 293 is tied around the waist and secured with Velcro 294 for easy connection to the human body and convenient operation.

[0036] Furthermore, a sleeve block 271 is fixedly installed on the outer side wall of the anti-slip plate 27. The sleeve block 271 has a sleeve hole 272 that matches the connecting rod 26. The sleeve block 271 is fitted onto the connecting rod 26. The sleeve block 271 is provided with a first fastening bolt 273 that passes through the sleeve hole 272 and the connecting rod 26.

[0037] In use, the sleeve 271 on the anti-slip plate 27 is aligned with the connecting rod 26 and inserted, so that the sleeve hole 272 fits on the connecting rod 26, and is fixed by the first fastening bolt 273, which is convenient for disassembly and assembly, and easy for storage, carrying and maintenance.

[0038] Example 2

[0039] The collar 1 includes a semi-circular fixed frame 11 that is fixedly connected to the connecting block 21. Two symmetrically distributed quarter-circle sleeve frames 12 are hinged at both ends of the fixed frame 11. A fixed block 13 is fixedly installed on the end of each sleeve frame 12 away from the fixed frame 11. A second fastening bolt 14 is provided through the fixed block 13.

[0040] In use, the two socket brackets 12 are rotated and unfolded from both ends of the fixed bracket 11, and then placed on the cement pole. Then, the two socket brackets 12 are rotated again to merge them. Then, the two fixed blocks 13 are fixed by the second fastening bolt 14 to complete the quick installation of the collar 1 and the cement pole, which is convenient and fast.

[0041] Furthermore, a number of ball grooves 15 are evenly distributed in a ring array on the inner sidewalls of the fixing frame 11 and the socket frame 12, and ball balls 16 are rolled in the ball grooves 15.

[0042] During use, in order to ensure smooth sliding between the collar 1 and the cement pole during the climbing process, the ball bearings 16 inside the collar 1 contact the outer wall of the cement pole to roll and connect, reducing friction and preventing jamming.

[0043] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
