Anti-falling safety device

Abstract

The invention discloses an anti-falling safety device which can be fixedly connected with angle iron of a power distribution line iron tower, and belongs to the technical field of high-altitude anti-falling protection. The anti-falling safety device comprises a hanging plate, a sliding plate, a locking tongue and an adjusting assembly. A hook is arranged at one end of the hanging plate in an extending manner, and the other end of the hanging plate is fixedly connected with a safety rope. The hook can be hung to one side plate of the angle iron. A first groove hole is formed in the hanging plate in the extending direction. A clamping groove belt is arranged on one side, away from the hook, of the hanging plate. The clamping groove belt comprises multiple clamping grooves arranged side by side in the extending direction. The sliding plate is in sliding connection with the hanging plate. The lock tongue is arranged on the sliding plate. One end of the locking tongue can penetrate throughthe first groove hole so as to abut against the other side plate of the angle iron. The adjusting assembly comprises an adjusting tongue arranged on the sliding plate. The adjusting tongue can be connected with one clamping groove in a clamped manner when the locking tongue is connected with the other side plate of the angle iron in an abutting manner. The anti-falling safety device can be fixedlyconnected with the angle iron stably, the locking distance between the hook and the locking tongue can be adjusted, and the anti-falling safety device has universality.

Description

technical field [0001] The invention relates to the technical field of high-altitude fall protection, in particular to an anti-fall safety device for climbing a distribution line iron tower. Background technique [0002] In the construction and maintenance of power transmission and distribution lines, it is often necessary to climb the power tower for tower climbing operations. Anti-fall hooks must be used during tower climbing operations to protect the safety of tower climbing workers. [0003] At present, the main anti-fall measures in the power maintenance industry are to install anti-fall guide rails on the main material of distribution line iron towers and use self-locking hooks to connect operators and towers. The cost of installing anti-fall guide rails is relatively high, and installation requires With a lot of manpower and financial resources, it is difficult to achieve full coverage of all poles and towers. At the same time, it also increases the maintenance work ...

Problems solved by technology

[0003] At present, the main anti-fall measures in the power maintenance industry are to install anti-fall guide rails on the main material of distribution line iron towers and use self-locking hooks to connect operators and towers. The cost of installing anti-fall guide rails is relatively high, and installation requires With a lot of manpower and financial resources, it is difficult to achieve full coverage of all poles and towers. At the same time, it also increases the maintenance work of installing the anti-fall guide rails, which increases the cost

At the same time, the existing anti-falling self-locking hooks are generally movably set on the angle irons of the distribution line towers. During the movement of the operators, the hooks are prone to jamming when sliding relative to the angle irons, which limits the operator's freedom of movement. At the same time, during the movement of the operator, when the hook and the angle iron get stuck, it may generate a relative pulling force on the operator, which poses a certain safety hazard

Moreover, the existing self-locking hooks cannot change the size range of the hooking or locking according to the different sizes of the angle irons of the distribution line iron towers, which can no longer meet the actual work needs of the high-altitude workers.
