Description

Technical Field

[0001] This utility model belongs to the technical field of fall protection devices, specifically a fall protection auxiliary device for power transmission tower climbing. Background Technology

[0002] Tower climbing is a critical operation in power maintenance, referring to workers climbing transmission line towers to perform equipment inspections, troubleshooting, repairs, and maintenance to ensure the safe and stable operation of transmission lines. This operation must strictly follow safety regulations and use professional protective equipment such as safety belts and self-locking devices to ensure the safety of personnel working at heights.

[0003] When climbing power transmission line towers, fall arrestors are required. By connecting the fall arrestor to the guide rail, it can prevent operators from falling if they lose their footing. At the same time, the safety belt worn by the operator is connected to a safety buckle. Each time they climb upwards, the safety buckle needs to be put on the foot spikes, thus providing a double fall protection function. However, each time they climb upwards, they need to repeatedly unlock and remove the safety buckle from the foot spikes, which makes the operator's physical strength depleted quickly, easily fatigued, and not conducive to long-term tower climbing operations. Therefore, improvements are needed. Utility Model Content

A collar 4 is fixedly connected to the outer end of the safety rope 2. Hand fixing straps 5 are movably sleeved on both sides of the outer surface of the collar 4. A movable sleeve 6 is movably sleeved on the outer side of the outer surface of the safety rope 2. The inner surface of the movable sleeve 6 is fixedly connected to the outer surface of the collar 4. A movable box 7 is movably sleeved on the outer surface of the safety rope 2. An elbow strap 8 is fixedly connected to the front end of the movable box 7. A fixing toothed plate 9 is fixedly installed on the front side of the inner cavity of the movable box 7. The rear end of the fixing toothed plate 9 is movably connected to the outer surface of the safety rope 2. A bolt 10 is threaded on the inner back of the movable box 7. A movable toothed plate 11 is movably sleeved on the front end of the bolt 10. The front end of the movable toothed plate 11 is movably connected to the outer surface of the safety rope 2. A rotating plate 12 is fixedly sleeved on the rear side of the outer surface of the bolt 10.

[0026] The operator connects the carabiner 1 to the safety harness worn on their body, and then uses the elbow strap 8 to put it on the elbow, so that the Velcro inside the elbow strap 8 sticks together, thereby connecting the elbow strap 8 to the elbow. Then, the operator puts their index finger and thumb inside the hand fixing strap 5, so that the loop 4 is located in the palm of the hand, so that the loop 4 can be put on the foot spike when the operator holds the foot spike.

[0027] The safety rope 2 has a movable box 13 that is movably sleeved on its outer surface. A fixed rod 14 is fixedly installed inside the movable box 13. The outer surface of the fixed rod 14 is movably connected to the outer surface of the safety rope 2.

[0028] By setting a fixing rod 14, the safety rope 2 can be wrapped around the fixing rod 14, thereby folding the safety rope 2.

[0029] The movable box 13 has an adjusting rod 15 movably connected to the left side inside. The outer surface of the adjusting rod 15 is movably connected to the outer surface of the safety rope 2. The top of the adjusting rod 15 is fixedly installed with a mounting box 16 located on the top of the movable box 13.

[0030] The operator can push the mounting box 16 to move the adjusting rod 15 to the right, thereby shortening the folded length of the safety rope 2 and adjusting the length of the safety rope 2.

[0031] The mounting box 16 has a locking block 17 that is movably fitted on both the front and rear sides inside, and a push plate 18 is fixedly connected to the top of the locking block 17.

[0032] The operator can push the two push plates 18 to move in opposite directions, thereby causing the push plates 18 to move the locking block 17, so that the locking block 17 enters the interior of the mounting box 16.

[0033] There are two locking blocks 17, and a spring 19 is fixedly connected between the two locking blocks 17.

[0034] When the two locking blocks 17 move toward each other, the spring 19 will be compressed, so that the spring 19 can move the two locking blocks 17 outward under the elastic recovery action.

[0035] The top of the active box 13 is fixedly equipped with a side plate 20, and the inside of the side plate 20 is provided with a slot 21. The inner surface of the slot 21 is movably connected to the outer surface of the card block 17.

[0036] When the locking block 17 is inside the locking slot 21, it will fix the mounting box 16, thereby fixing the adjusting rod 15.

[0037] The bottom of the adjusting rod 15 is fixedly connected to a connecting block 22, and a round rod 24 is movably sleeved inside the connecting block 22. Fixing blocks 23 are fixedly sleeved on both the left and right sides of the outer surface of the round rod 24, and the top of the fixing blocks 23 is fixedly connected to the bottom of the movable box 13.

[0038] When the adjusting rod 15 moves, it will cause the connecting block 22 to move along the outer surface of the round rod 24, thereby limiting the adjustment rod 15.

[0039] Working principle and usage process of this utility model:

[0040] First, the operator connects the carabiner 1 to the safety harness worn on their body. Then, by rotating the rotating plate 12, the bolt 10 moves the movable toothed plate 11 backward, thereby disengaging the movable toothed plate 11 from the safety rope 2 and releasing the fixation of the movable box 7. At this point, the operator can adjust the position of the elbow strap 8 by moving the movable box 7. After the position of the elbow strap 8 is adjusted, the rotating plate 12 is rotated again, causing the movable toothed plate 11 to engage with the fixed toothed plate 9 to clamp the safety rope 2, thereby fixing the position of the elbow strap 8. Then, the elbow strap is... The strap 8 is looped around the elbow, and the Velcro inside the elbow strap 8 is fastened together, thus connecting the elbow strap 8 to the elbow. Finally, the index finger and thumb are looped inside the hand fixing strap 5, so that the loop 4 is located in the palm of the hand. This allows the loop 4 to be looped onto the foot spike when the operator holds the foot spike, making it convenient for the operator and reducing the operator's labor intensity. In the event of a fall, the safety rope 2 will generate downward force, causing the movable sleeve 6 to rise and the loop 4 to tighten, thus making the loop 4 firmly looped onto the foot spike.

[0041] When the operator needs to adjust the length of the safety rope 2, first push the two push plates 18 to move in opposite directions, so that the push plates 18 drive the locking block 17 to move into the mounting box 16, so that the locking block 17 disengages from the inside of the locking groove 21, thereby releasing the fixing effect on the mounting box 16 and the adjusting rod 15. At this time, push the mounting box 16 to the right, so that the adjusting rod 15 moves to the right at the same time, thereby shortening the folded length of the safety rope 2, thus lengthening the safety rope 2, making it more convenient for people of different body types to use.
