Problems solved by technology

Because the existing anti-fall equipment is usually hung on the hanging basket or the utility pole tower, when the staff falls, the instantaneous force received by the anti-fall device is very large, which makes the anti-fall device very easy to be damaged, and, in the anti-fall device When the dropper is subjected to an instantaneous force, the instantaneous force generated by the safety belt connected to the worker is very large, which is likely to cause injury to the worker

Embodiment 1

[0022] In this embodiment, in order to avoid accidents caused by the upper end of the safety belt falling off the hanging ring, preferably, a baffle 113 is provided at the end of the safety belt 111 close to the hanging ring 110, so that the width of the baffle 113 is greater than the diameter of the through hole 108. When one end of the safety belt connection ring is broken, the baffle can be hooked above the base to prevent the safety belt from coming out of the through hole directly. Since the momentary force on the safety belt will be relatively large in the event of a fall, in order to avoid the baffle The contact base breaks. In this embodiment, a rubber cushion 114 is provided at the end of the baffle 113 away from the hanging ring 110, so that the rubber cushion is bonded to the safety belt by superglue, and the upper end of the rubber cushion is bonded to the baffle. On the lower end face, the width of the rubber pad 114 is greater than the diameter of the through hole...

Embodiment 2

[0024] In this embodiment, in order to facilitate the positioning of the high-strength spring and avoid the deflection of the end of the high-strength spring away from the hanging ring at the moment when the pressure bar rotates, it will fall off from the lower hook. Preferably, a through groove 115 is provided on the side wall of the lower hook 102, so that The through groove is located below the latch, and the through groove is arranged along the length direction of the lower hook, so that the through groove communicates with the inner side and the outer side of the lower hook, and a positioning pin 116 is arranged on the side wall of the hanging ring 110, so that the positioning pin is fixedly connected on the side wall of the hanging ring Set the high-strength spring 112 on the outside of the positioning pin 116, so that the diameter of the positioning pin is smaller than the inner diameter of the high-strength spring, and at the same time make the diameter of the positionin...

Embodiment 3

[0027]In order to prevent the lower hook from falling off from the upper hook, in this embodiment, preferably, a return spring 117 is arranged on the opposite end faces of the two lower hooks 102, so that the return spring connects the two lower hooks so that the two lower hooks can be reset The limitation of the spring can be kept at a fixed position. When installing, the bolts on the two lower hooks are respectively hooked in the jacks on the upper hook, and the latches 106 of the two lower hooks 102 are respectively hooked on the corresponding upper hooks 103 Back-moving spring 117 is in natural state when in the upper jack 104. Under the action of the return spring, the two lower hooks and the upper hook can be kept stable to avoid deformation of the lower hook.

Abstract

The invention discloses a fall preventing device for electric power aerial operation. The device comprises a base, and two lower hanging hooks arranged on the base; upper hanging hooks are respectively arranged above the two lower hanging hooks; the lower hanging hooks are both U-shaped structures downwards opened; the two upper hanging hooks are U-shaped structures downwards opened; insertion holes are respectively formed in the end parts of two ends of the upper hanging hooks; mounting holes are formed in the base; the end parts of the lower hanging hooks are respectively inserted in the corresponding mounting holes to extend above the base; the upper ends of the lower hanging hooks are respectively bent to the outer sides to form bolts; the tail ends of the bolts are perpendicularly pointed to the base direction; and the bolts on the lower hanging hooks are respectively inserted in the insertion holes in the corresponding upper hanging hooks. As a safety belt is connected to a pressing rod, when the fall occurs, the safety belt can buffer instant acting force under the effect of elastic force of a high-strength spring to prevent personal injury.

Description

technical field [0001] The invention relates to an electric high-altitude operation fall prevention device. Background technique [0002] During the maintenance of overhead cables, in order to avoid the occurrence of staff falling accidents, it is necessary to set up anti-falling equipment. Because the existing anti-fall equipment is usually hung on the hanging basket or the utility pole tower, when the staff falls, the instantaneous force received by the anti-fall device is very large, which makes the anti-fall device very easy to be damaged, and, in the anti-fall device When the dropper is subjected to an instantaneous force, the instantaneous force generated by the safety belt connected to the worker is very large, which is likely to cause injury to the worker. Contents of the invention [0003] The object of the present invention is to provide a kind of anti-falling device for electric high-altitude operation. By connecting the safety belt to the pressure bar, when a ...
