Technical Field

[0001] The utility model relates to the technical field of climbing protection, in particular to a climbing safety protection device. Background Art

[0002] Electric power transmission generally adopts high-hanging lines or underground lines. Most transmission lines adopt high-hanging lines. When workers inspect and repair high-hanging lines, they often need to climb to high places for maintenance. During the climbing process, setting a safety rope and clamping it with the contact of the limiter and the surface of the safety rope can avoid accidental falls while climbing.

[0003] The existing safety protection devices mainly rely on the operator to manually adjust the clamping position by clamping the safety rope. The position needs to be readjusted every time a certain distance is climbed, which is cumbersome to operate. In addition, during a fall from a height, the fall is restricted by rigid pulling, causing inertial damage to the waist of the climber caused by the safety belt.

[0004] In view of this, research and improvement are carried out on the existing problems, and a climbing safety protection device is provided to solve the current problems. The purpose is to solve the problems and improve the practical value through this technology. Utility Model Content

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] A climbing safety protection device provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0025] Combination Figure 1-5As shown, the utility model provides a climbing safety protection device, including: a casing seat 100, a descending clamp 200 and a slow-speed conveying box 300, the surface of the casing seat 100 is fixed with a first positioning seat 110 and a second positioning seat 120 respectively located at the upper and lower ends, the surfaces of the first positioning seat 110 and the second positioning seat 120 are respectively movably mounted with a connecting rod 130 and an elastic connecting rod 140, the number of the connecting rod 130 and the elastic connecting rod 140 are both two groups and are symmetrically arranged about the casing seat 100, the top end of the elastic connecting rod 140 is rotatably connected to the surface of the connecting rod 130, the surface of the connecting rod 130 is rotatably mounted with a clamping wheel 150, and the surface of the clamping wheel 150 is provided with an axis Rod 151, a transmission tooth 320 sleeved on the surface of the shaft rod 151 is rotatably installed on the inner side of the deceleration box 300, and a reduction tooth 310 fixed to the surface of the second positioning seat 120 and in transmission engagement with the surface of the transmission tooth 320 is provided on the inner side of the deceleration box 300. The reduction tooth 310 is used to give the transmission tooth 320 a rotation resistance. The descending clamp 200 includes a first chuck 210, a second chuck 220, and two guide rods 230 movably connected to the bottom ends of the first chuck 210 and the second chuck 220. The first chuck 210 and the second chuck 220 are rotationally connected in staggered directions and are respectively sleeved on the surfaces of the two shaft rods 151, and the bottom ends of the two guide rods 230 are rotationally connected.

[0026] In this embodiment, two guide rods 230 are arranged in a V shape and a connecting ring 231 is movably installed on the surface. The connecting ring 231 is used to connect with the surface of the safety belt.

[0027] In this embodiment, the first chuck 210 and the second chuck 220 are arranged in an X shape, the surfaces of the first chuck 210 and the second chuck 220 are rotatably connected, and the bottom ends of the first chuck 210 and the second chuck 220 are rotatably connected to the top end of the guide rod 230.

[0028] Specifically, during a descending movement such as falling, by pulling the connecting ring 231, the guide rod 230 controls the first clamp 210 and the second clamp 220 to deflect and move, so that the clamping wheel 150 clamps the surface of the safety rope.

[0029] In this embodiment, a through hole groove is opened on the surface of the casing seat 100, and one side of the clamping wheel 150 passes through the through hole groove on the surface of the casing seat 100 and abuts against the surface of the safety rope.

[0030] In this embodiment, the elastic connecting rod 140 is a U-shaped metal spring structure, and two sections of the elastic connecting rod 140 are rotatably connected to the second positioning seat 120 and the end of the connecting rod 130 respectively.

[0031] Specifically, the connecting rod 130 is elastically pulled under the connection of the elastic connecting rod 140, so that the connecting rod 130 is located on the opposite surface of the second positioning seat 120 and the connecting rod 130 and abuts against the surface of the safety rope.

[0032] In this embodiment, the transmission teeth 320 on the surfaces of the two clamping wheels 150 are meshed with each other for transmission. The inner side of the reduction teeth 310 is rotatably sleeved with a positioning rod 311 , and the positioning rod 311 is fixed to the surface of the second positioning seat 120 .

[0033] Furthermore, a damping brake pad 312 located inside the reduction tooth 310 is fixedly mounted on the surface of the positioning rod 311 , a spring sheet is provided inside the reduction tooth 310 and a friction sheet is abutted on one side of the spring sheet, and the friction sheet is slidably abutted against the surface of the damping brake pad 312 .

[0034] Specifically, when the damping brake plate 312 contacts the surface of the friction plate, the rotation of the reduction gear 310 is suppressed, thereby giving the clamping wheel 150 a certain rotation resistance to achieve a slow descent motion.

[0035] The working principle and use process of this utility model:

[0036] During the climbing operation, the safety rope is passed through the inside of the casing seat 100, and the climber wears a safety belt and hooks it to the surface of the connecting ring 231. During the normal climbing movement, the first clamp 210 and the second clamp 220 are in a non-stressed state, and the elasticity of the elastic connecting rod 140 can keep the expansion effect of the connecting rod 130 and the clamping wheel 150 from contacting the surface of the safety rope. The clamping wheel 150 freely opens the safety rope surface without clamping and limiting effect, so that the descending clamp 200 and the casing seat 100 can automatically follow the free ascending movement of the climbing; and During an accidental fall or downward movement, the falling force pulls the guide rod 230 during the downward movement, and when the first clamp 210 and the second clamp 220 are under force, the clamping wheel 150 contacts the surface of the safety rope and moves downward along the surface of the safety rope. The clamping wheel 150 abuts against the surface of the safety rope and rotates, thereby driving the reduction gear 310 to rotate. Under the abutment of the damping brake pad 312 on the surface of the positioning rod 311, the rotation of the reduction gear 310 is suppressed, thereby giving the reduction gear 310 and the clamping wheel 150 a rotation resistance, suppressing the sliding speed of the casing seat 100 on the surface of the safety rope, and performing a low-speed descent.

[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
