Anti-fall hook

Abstract

The invention relates to an anti-fall hook. The upper part of a hook body is provided with a hook bracket; the hook is fixed on the hook body by the hook bracket through a pin shaft; a guiding nut is connected with an upper bracket hole on the middle part of the hook body; a connecting plate and a ribbed plate are fixed on the upper bracket on the middle part and a lower hook on the lower part of the hook body by using an electric welding method; the upper part of a screw is connected with the hook through the pin shaft; a transmission wheel is fixed on the guiding nut on the lower part of the screw through a ring and a nut; a crank shaft is connected through a crank sleeve hole; a crank shaft pin is fixed on the crank shaft; a crank sleeve is fixed to the crank hinge by using an electric welding method; and the crank hinge is connected with a hinge hole of the connecting plate through a pin shaft. The anti-fall hook has the advantages that: an opening formed by the included angle of the hook is adjustable, so that the hook can be prevented from moving on a cable; the included angle of axes of two transmission gears is adjustable, so that the anti-fall hook can be suitable for locking at different positions; and the anti-fall hook has a simple structure and is convenient to operate.

Description

【Technical field】 [0001] The invention relates to the technical field of electric power maintenance, in particular to an anti-falling hook. 【Background technique】 [0002] Chinese patent application number 200820178737.2 relates to a fall prevention device, which is composed of a high-strength expansion bolt fixed on the wall and a high-strength fixing ring fixed to the inner core of the expansion bolt or integrated with the inner core of the expansion bolt. The utility model is fixed at a suitable position at the wall-piercing casing of the substation, and the hooks on the safety belts used by the operators can be hung on it firmly to ensure the personal safety of the operators. The structure is simple, the mechanical strength is high, and it is very convenient and safe. The hanging and taking off of the belt is safe and convenient to use, and the installation is simple, and it is widely used in the inspection and maintenance of various substation wall bushings.

AI Technical Summary

Problems solved by technology

[0005] With the continuous development of the electric power industry, there are more and more power grids and transmission and transformation stations, and the maintenance workload of high-altitude lines is increasing. The original hook has no anti-fall function, and the hook is easy to move on the cable, which seriously affects the safety of high-altitude operations.
