High-altitude work safety belt and its use

Abstract

The invention discloses an aerial working safety belt which comprises a waistcoat type safety belt body, a main hook, an auxiliary hook, braids, braid furling devices, a main hook control device and an auxiliary hook control device. The lower end of a movable hook body of the main hook and the lower end of a movable hook body of the auxiliary hook are both connected with the lower ends of fixed hook bodies through a main hook locking device and an auxiliary hook locking device. A using method of the aerial working safety belt includes the following steps: (1) wearing the aerial working safety belt, (2) starting a main hook electric control device, (3) respectively hooking the main hook and the auxiliary hook, (4) respectively locking the main hook and the auxiliary hook, (5) moving the main hook, (6) moving the auxiliary hook, (7) hooking the main hook or the auxiliary hook again, and (8) taking down the main hook and the auxiliary hook. According to the aerial working safety belt and the using method, a dual-safety mechanism that the main hook and the auxiliary hook are used for hooking at the same time is adopted, the automatic locking function when falling occurs is achieved, and movement space of a worker is enlarged. The self-locking function of the main hook or the auxiliary hook is achieved, the one-way interlocking function between the main hook and the auxiliary hook is achieved, and the aerial working safety is guaranteed.

Description

technical field [0001] The invention relates to a safety protection device for working at heights, in particular to a safety protection device for working at heights with multiple functions such as self-locking, interlocking, unlocking and warning, and a method for using the safety protection device for working at heights. It belongs to the technical field of safety devices. Background technique [0002] In industries such as construction and electric power that require high-altitude operations, operators must wear high-altitude work safety belts when working at heights. The existing high-altitude work safety belts have relatively single functions and lack integral safety protection systems and devices.

Problems solved by technology

[0002] In industries such as construction and electric power that require high-altitude operations, operators must wear high-altitude work safety belts when working at heights. The existing high-altitude work safety belts have relatively single functions and lack integral safety protection systems and devices.

[0003] The application number is 200420052642.8, and the utility model patent named "cuffed seat belt hook" proposes a seat belt hook in the form of handcuffs, which solves the function of automatic locking of the hook itself, but its function is too single and does not have the ability to increase the work. The function of the personnel's activity space and the interlocking function between the hooks, the safety performance cannot be improved

[0004] The application number is 02255103.4, and the utility model patent named "safety belt warning device for high-altitude work" proposes a warning reminder device, which solves the safety accident caused by the staff forgetting or failing to hook the safety belt hook

However, it only provides a warning device, and does not form a good connection and control with the seat belt. At the same time, it lacks the electronic interlock protection device and system between the hooks, and does not have the ability of electronic control.

[0005] Soochow University's master's degree thesis "Research and Development of Two-leg Speed ​​Difference Controller" compared the performance of the existing speed difference controllers (also called retractors) used in various industries, and designed a new type of speed difference controller. The speed difference controller device proposes the concept and device of applying centrifugal force for automatic locking. The structure is simple and effective, but it lacks the self-locking protection of the hook and the interlocking function between the hooks.
