Description
Technical Field
[0001] This utility model relates to the field of climbing equipment for power transmission towers, and in particular to a climbing protection device for power transmission towers. Background Technology
[0002] Power transmission towers are essential equipment in power transmission, numbering in the thousands and widely distributed. During the maintenance of power transmission lines, workers must climb to the top of the tower and then cross the crossarm to reach the work site. Currently, common safety measures for workers climbing power towers for high-altitude maintenance operations include rail-mounted fall protection and double-hook alternating protection.
[0003] Traditional double-hook structures still have certain shortcomings in use: When using current double hooks, workers need to first attach one hook to a certain position on the tower, then climb a short distance using foot spikes to attach the other hook, then climb back down to the original position to retrieve the first hook before climbing higher again. During this process, it is quite troublesome for workers to open and close the hook when removing it, and when climbing back up to retrieve the hook, they usually put the hook on their arm so that their palm can hold the foot spikes. After climbing to a higher position, they then remove it from their wrist and fix it. Overall, the operation is inefficient.
[0004] Therefore, it is necessary to provide a new climbing protection device for power transmission towers to solve the above-mentioned technical problems. Utility Model Content
[0005] The technical problem solved by this utility model is to provide a climbing protection device for power towers that facilitates workers in opening and closing the hook and improves climbing efficiency.
[0006] To solve the above-mentioned technical problems, the present invention provides a climbing protection device for power transmission towers, comprising: a hook assembly, wherein two sets of hook assemblies are provided, each hook assembly includes a fixing member, one end of which is hinged to a rotating member, a handle is fixedly connected to the side of the fixing member away from the rotating member via a connecting block, an inner rod is slidably connected inside the handle, a receiving chamber is provided inside the handle, and a movable rod is fixedly connected to the top of the inner rod through the receiving chamber, the movable rod being located outside the handle;
[0007] A limiting component is fixedly connected to the surface of the inner rod located inside the receiving compartment. A compression spring is fixedly connected between the limiting component and the inner wall of one side of the receiving compartment. The compression spring is located on the outside of the inner rod. A through groove is opened on the surface of the handle located on one side of the receiving compartment. A connecting rod is hinged between the end of the inner rod and the rotating component.
[0008] As a further embodiment of this utility model, a connector is fixedly connected to the bottom of each of the two fixing members, a safety rope is fixedly connected to the end of the connector, and a fixing block is fixedly connected between the ends of the two safety ropes.
[0009] With the above technical solution, when using the device, first fix a single hook to a certain firm position on the power tower, then climb up a short distance and hook on another single hook, then move down to the original position to retrieve the previous single hook and climb up again. Although the double hook structure increases the time required for climbing, it can effectively achieve safety protection during the climbing process.
[0010] As a further embodiment of this utility model, a potential energy absorption bag is fixedly connected to the surface of the fixing block, and a safety hook is fixedly connected to the end of the potential energy absorption bag relative to the fixing block.
[0011] With the above technical solution, the safety hook is fixed to one's own safety belt before use. If a fall occurs during climbing, the potential energy absorption bag between the safety rope and the safety hook can effectively dissipate the impact force generated by the human body.
[0012] As a further embodiment of this utility model, a first groove is provided on one side wall surface of the movable rod, a locking block is slidably connected inside the first groove, and a plurality of return springs are fixedly connected between the locking block and the inner wall of the first groove.
[0013] With the above technical solution, in the traditional use of hooks, when workers need to retrieve them, they must first find and pinch the fixing part, then open their palms to grab the rotating part on the other side and pull it inward. The same operation is required when re-fixing. Some power towers are over 100 meters high, but when workers use double hooks to climb, they can only move a small distance each time, so workers' fingers easily get tired and sore. In this device, workers only need to hold the handle, then extend their thumbs to press the locking block to retract it into the first groove, then grab the second groove and press down on the movable rod. During this process, the return spring is compressed and the bottom of the inner rod moves down. The inner rod will pull the rotating part inward through the connecting rod, so that the worker can retrieve the hook from the power tower frame. This structural design makes it easier for workers to operate without having to open their palms and press hard each time.
[0014] As a further embodiment of this utility model, the surface of the card block is provided with an inclined surface, and a second groove is provided on one side of the inclined surface.
[0015] With the above technical solution, when the worker releases his thumb, the movable rod can smoothly extend out of the handle under the reaction force of the compression spring, and the locking block will pop out again under the reaction force of the return spring. In this way, when the connecting rod on the inner side of the fixed part and the rotating part is under pressure, it will be unable to move due to the restriction of the locking block.
[0016] As a further embodiment of this utility model, a limiting groove is provided at the end of the rotating member, and one end of the fixing member relative to the rotating member is located inside the limiting groove.
[0017] With the above technical solution, when the user presses down the movable rod, the bottom of the inner rod moves down, causing the connecting rod to pull the rotating part open. At this time, the end of the fixed part disengages from the limiting groove, and the worker can hang the hook on a certain position on the iron tower. After releasing the hand, the limiting groove at the end of the rotating part re-abuts against the end of the fixed part, thereby limiting the position.
[0018] As a further embodiment of this utility model, a hanging piece is fixedly connected to the top of the movable rod, and the surface of the hanging piece is provided with a bent portion.
[0019] With the above technical solution, in the traditional structure, when workers retrieve the single hook and climb upwards, they usually put the single hook on their arm so that their palms can grip the foot spikes. After climbing to a higher position, they take it off their wrists and fix it. The overall operation is inefficient. In this device, the worker holds the handle, then attaches the hanging part to the foot spike on one side. Then, by exerting force with their arm, they can move upwards. After reaching the designated position, they find the right position on the tower, extend their thumb to compress the locking block, and move it down to re-attach. This structural design increases the worker's operating efficiency and improves the speed of operation.
[0020] Compared with related technologies, the climbing protection device for power transmission towers provided by this utility model has the following advantages:
[0021] Beneficial effects:
[0022] 1. In this utility model, when using a traditional hook, workers need to find and hold the fixing part, then open their palms to grab the rotating part on the other side and pull it inward. The same operation is required when re-fixing. Some power towers are over 100 meters high, but when workers use double hooks to climb, they can only move a small distance each time, so workers' fingers easily get tired and sore. In this device, workers only need to hold the handle, then extend their thumbs to press the locking block to retract it into the first groove, then grab the second groove and press the movable rod downward. During this process, the return spring is compressed and the bottom of the inner rod moves down. The inner rod will pull the rotating part inward through the connecting rod, so that workers can retrieve the hook from the power tower frame. This structural design makes it easier for workers to operate without having to open their palms and press hard each time.
[0023] 2. In this utility model, in the traditional structure, when a worker retrieves the single hook and climbs upwards, in order to grip the foot spikes with their palm, they usually put the single hook on their arm, and then take it off their wrist and fix it after climbing to a higher position. The overall operation is inefficient. In this device, the worker holds the handle, then fastens the hanging part to the foot spike on one side, and then moves upwards by exerting force with their arm. After reaching the designated position, they find the right position on the tower, extend their thumb to compress the locking block and move it down to re-attach. This structural design makes the worker's operation more efficient and can improve the speed of operation. Attached Figure Description

[0031] Please combine Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of a climbing protection device for power transmission towers according to this utility model. Figure 1 ; Figure 2 This is a schematic diagram of the overall structure of a climbing protection device for power transmission towers according to this utility model. Figure 2 ; Figure 3 This is a partial structural cross-section of a climbing protection device for power transmission towers according to the present invention. Figure 1 ; Figure 4 This is a partial structural cross-section of a climbing protection device for power transmission towers according to the present invention. Figure 2 A climbing protection device for power transmission towers includes:
[0032] Hook assembly 1, which is provided in two sets, includes a fixing member 2, one end of which is hinged to a rotating member 10, and a handle 7 is fixedly connected to the side surface of the fixing member 2 away from the rotating member 10 through a connecting block. An inner rod 17 is slidably connected inside the handle 7, and a receiving chamber 13 is provided inside the handle 7. The top of the inner rod 17 passes through the receiving chamber 13 and is fixedly connected to a movable rod 9, which is located outside the handle 7.
[0033] A limiting member 14 is fixedly connected to the surface of the inner rod 17 located in the receiving chamber 13. A compression spring 15 is fixedly connected between the limiting member 14 and the inner wall of one side of the receiving chamber 13. The compression spring 15 is located on the outside of the inner rod 17. A through groove 8 is opened on the surface of the handle 7 located on one side of the receiving chamber 13. A connecting rod 11 is hinged between the end of the inner rod 17 and the rotating member 10.
[0034] like Figure 1-4 As shown, a connector 12 is fixedly connected to the bottom of each of the two fasteners 2, a safety rope 3 is fixedly connected to the end of the connector 12, and a fixing block is fixedly connected between the ends of the two safety ropes 3.
[0035] When using this device, first fix a single hook to a secure position on the power tower, then climb up a short distance and attach another single hook, then move down to the original position to retrieve the previous single hook and climb up again. Although the double hook structure increases the time required for climbing, it can effectively ensure safety during the climbing process.
[0036] like Figure 1-4 As shown, a potential energy absorption bag 4 is fixedly connected to the surface of the fixed block, and a safety hook 5 is fixedly connected to the end of the potential energy absorption bag 4 relative to the fixed block.
[0037] Before use, secure the safety hook 5 to your safety belt. If a fall occurs during the climb, the potential energy absorption bag 4 between the safety rope 3 and the safety hook 5 can effectively absorb the impact force generated by the human body.
[0038] like Figure 1-4 As shown, a first groove 19 is provided on one side wall surface of the movable rod 9. A locking block 21 is slidably connected inside the first groove 19. Several return springs 20 are fixedly connected between the locking block 21 and the inner wall of the first groove 19.
[0039] In traditional hooks, when workers need to retrieve the hook, they must first locate and grip the fixing part 2, then open their palm to hold the rotating part 10 on the other side and pull it inward. The same operation is required when re-fixing. Some power towers are over 100 meters high, but when workers use double hooks to climb, they can only move a small distance each time, which easily leads to finger fatigue and soreness. In this device, workers only need to hold the handle 7, then extend their thumb to press the locking block 21 to retract it into the first groove 19, then hold the second groove 22 and press down on the movable rod 9. During this process, the return spring 20 is compressed and the bottom of the inner rod 17 moves down. The inner rod 17 will pull the rotating part 10 inward through the connecting rod 11, allowing the worker to retrieve the hook from the power tower frame. This structural design eliminates the need for workers to open their palms and press down forcefully each time, making operation much easier.
[0040] like Figure 1-4 As shown, the surface of the card block 21 is provided with an inclined surface 16, and a second groove 22 is provided on one side of the inclined surface 16.
[0041] When the worker releases his thumb, the movable rod 9 can smoothly extend out of the handle 7 under the reaction force of the compression spring 15, and the locking block 21 will pop out again under the reaction force of the return spring 20. In this way, when the connecting rod 11 inside the fixed part 2 and the rotating part 10 is under pressure, it will be unable to move due to the restriction of the locking block 21.
[0042] like Figure 1-4 As shown, a limiting groove 18 is provided at the end of the rotating member 10, and one end of the fixing member 2 relative to the rotating member 10 is located inside the limiting groove 18.
[0043] When the user presses down the movable rod 9, the bottom of the inner rod 17 moves down, causing the connecting rod 11 to pull the rotating part 10 open. At this time, the end of the fixing part 2 disengages from the limiting groove 18, and the worker can hang the hook on a certain position on the iron tower. After releasing the hand, the limiting groove 18 at the end of the rotating part 10 re-engages with the end of the fixing part 2, thereby limiting the position.
[0044] like Figure 1-4 As shown, a hanger 6 is fixedly connected to the top of the movable rod 9, and the surface of the hanger 6 is provided with a bent part.
[0045] In traditional structures, when workers retrieve a single hook and climb upwards, they typically loop the hook around their arm to grip the foot spikes. Once they reach a higher position, they remove the hook from their wrist and secure it. This overall operation is inefficient. In this device, however, the worker grasps the handle 7, attaches the hanging piece 6 to one side of the foot spike, and then moves upwards by exerting force with their arm. Once at the designated position on the tower, they find a suitable spot, extend their thumb to compress the locking block 21, and lower it to reattach the hook. This structural design increases worker efficiency and improves work speed.
[0046] The working principle of the climbing protection device for power transmission towers provided by this utility model is as follows:
[0047] First step: In the traditional use of hooks, when workers need to retrieve them, they must first find the fixing part 2 and pinch it, then open their palms to grab the rotating part 10 on the other side and pull it inward. The same operation is required when re-fixing. Some power towers are over 100 meters high, but when workers use double hooks to climb, they can only move a small distance each time, so workers' fingers easily get tired and sore. In this device, workers only need to hold the handle 7, then extend their thumbs to press the locking block 21 to retract it into the first groove 19, then grab the second groove 22 and press down on the movable rod 9. During this process, the return spring 20 is compressed and the bottom of the inner rod 17 moves down. The inner rod 17 will pull the rotating part 10 inward through the connecting rod 11, so that workers can retrieve the hook from the power tower frame. This structural design makes it easier for workers to operate without having to open their palms and press hard each time.
[0048] The second step: In the traditional structure, when workers retrieve the single hook and climb upwards, they usually put the hook on their arm so that their palms can grip the foot spikes. After climbing to a higher position, they take it off their wrists and fix it. The overall operation is inefficient. In this device, the worker holds the handle 7 and then fastens the hanging part 6 to the foot spike on one side. Then, by exerting force with their arm, they can move upwards. After reaching the designated position, they find the right position on the tower, extend their thumb to compress the locking block 21 and move it down to re-attach. This structural design makes the worker's operation more efficient and can increase the speed of operation.
[0049] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model. In terms of the technical aspects of this design principle, the setting of the power mechanism, power supply system and control system of the device is not fully described.
