Safety belt suspension device for working at heights

Abstract

The invention discloses a safety belt suspension device for aerial work, and relates to the technical field of the safety belt suspension device. The high-altitude work safety belt suspension device includes a safety belt body and two hanging straps fixedly connected to the rear of the safety belt body. The ends of the two hanging straps away from each other are fixedly connected to a bearing plate, and the rear end surfaces of the two bearing plates are connected to each other. A hook body is fixedly connected, and a cylinder is fixedly connected to the upper end surface of the inner cavity of the square box and above each third cam cylinder, and the cylinder and the slope of the third cam cylinder conflict, and the present invention can be used as one of the When the hook lock is opened, the other hook lock is stuck and closed, which avoids the situation that the two hook locks are opened and separated from the rope at the same time, and can also limit the position of the hook lock on the rope to avoid random sliding , to facilitate fixed-point operations, and greatly improve safety.

Description

technical field [0001] The invention relates to the technical field of safety belt suspension equipment, in particular to a safety belt suspension equipment for aerial work. Background technique [0002] Safety belts for working at heights are also known as omnidirectional safety belts or five-point safety belts. According to relevant national regulations, safety belts must be used for high-altitude operations. Safety belts should be inspected before use and tested regularly. When working on scaffolds without scaffolding or railings and the height exceeds 1.5m, safety belts or other reliable safety measures must be used. The seat belt must be hung on a solid structure or on a steel frame or wire rope specially designed for seat belts. [0003] At present, the maintenance personnel wear double-hook safety belts for safety protection. In the process of moving, they need to repeatedly hang the two hooks on the suspension cables in turn to ensure the safety of inspection operat...

AI Technical Summary

Problems solved by technology

[0004] 1. However, when using a double-hook seat belt, it is necessary to repeatedly untie and hang the seat belt hook. Repeatedly untying and hanging the hook for a long time may cause the situation that the hook is not fastened or both hooks are untied due to negligence. Then there may be a safety accident of falling;

[0005] 2. In addition, when the inspection operation at high altitude suddenly encounters a strong wind, because most of the existing safety belts are suspended on the suspension cables, the safety belt will slide or sway due to the strong wind, and the shaking will make the operator uncomfortable. Enables stable checks and has a large security risk
