Simple and detachable safety protection device for aerial work

Abstract

The invention relates to a simple and detachable safety protection device for aerial work. The simple and detachable safety protection device comprises a safety belt body, wherein a mounting plate isfixed on the front surface of the safety belt body, the mounting plate is rotationally connected with a winding shaft which is fixedly connected with a safety rope, a fixer is arranged at the end, faraway from the winding shaft, of the safety rope, and the mounting plate is connected with a connecting buckle used for being connected with the fixer; and a rotating shaft is sleeved with a torsion spring, one end of the torsion spring is fixed with the mounting plate, the other end of the torsion spring is fixed with the winding shaft, and the torsion spring is tightened when the safety rope extends out of the winding shaft. By the adoption of the technical scheme, after a user finishes working, the length of the safety rope meets the requirement that the user enters a room, then the connection between the fixer and the connecting buckle is released indoors, and the safety rope is pulled and wound indoors by rotating the winding shaft, so that the user is in the room to release safety protection when the mental state is poor, and the safety is better. The torsion spring is used for applying elastic force to the safety rope, when the safety rope needs to be wound, tension can be applied to the safety rope, and winding is easier.

Description

technical field [0001] The invention relates to the technical field of safety protection devices, in particular to a simple and detachable safety protection device for working at heights. Background technique [0002] At present, the safety protection device for working at heights refers specifically to safety belts for working at heights, also known as all-round safety belts or five-point safety belts. According to the national standard GB6095-2009, the belt body must be processed with high-strength polyester webbing or higher-strength fiber materials. of. [0003] Existing safety belts for high-altitude operations, as shown in the Chinese patent application number CN201820024362. For tightening belts, tailgates, positioning buttons, leg straps, leg pads, etc., the anchors generally use safety buckles. The user is protected within the range of the safety rope, and can return to the work platform by climbing the safety rope in case of a fall. [0004] The above-mentioned ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when working at heights, the guardrails or protective bars are generally on the outdoor work platform, such as tower crane maintenance, etc., are all climbed out from the cab and then the fixer is connected with the guardrails or protective bars, and the high-altitude Workers are highly concentrated during operation and are prone to fatigue after working for a long time. During the process of removing the fixer and entering the indoor environment, workers often relax their vigilance due to fatigue, which increases the incidence of accidents, so there is room for improvement
