High-altitude operation safety belt fixing device

Abstract

The invention belongs to the technical field of high-altitude operation, and particularly relates to a high-altitude operation safety belt fixing device. When the high-altitude operation safety belt fixing device is used for fixing a safety belt, a safety rope can be driven to pull a winding reel when an operator moves to be static in the descending process, and the safety rope is buffered through the elastic action of an elastic telescopic plate firstly; then, the winding reel starts to rotate, the rotation of the winding reel is hindered through the interaction force of the friction plate and the friction ring, then the safety rope is further buffered, the impact force of the safety rope is relieved, and stable connection between the fixing device and the guardrail is guaranteed; when the safety belt fixing device is used for fixing a safety belt and an operator horizontally moves in a large range, the whole fixing device does not need to be detached from a guardrail, the operator does not need to be transferred to a safety zone, and the operation convenience is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aerial work, and in particular relates to a safety belt fixing device for aerial work. Background technique [0002] High-altitude work safety belt, also known as full-body safety belt or five-point safety belt, is made of polyester and higher-strength webbing. High-altitude work safety belt is a protective product for people working at heights to prevent falling casualties, and consists of a belt body, a safety rope, a buffer bag and metal accessories. The existing safety belt fixing device is usually fixedly installed on the guardrail of the building, and there are the following problems when the safety belt for high-altitude operations is fixed: (1) a larger impact will be produced when the operator is moving to a standstill during the descent process The impact force transmitted to the fixing device through the safety rope will cause a large impact on the fixing device, affecting the fixing effect be...

Problems solved by technology

The existing safety belt fixing device is usually fixedly installed on the guardrail of the building, and there are the following problems when the safety belt for high-altitude operations is fixed: (1) a larger impact will be produced when the operator is moving to a standstill during the descent process The impact force transmitted to the fixing device through the safety rope will cause a large impact on the fixing device, affecting the fixing effect between the fixing device and the building guardrail, and even causing the fixing device to fall off from the guardrail in serious cases, posing a safety hazard (2) When the operator moves horizontally in a large range, it is necessary to remove the fixing device from the original position on the guardrail and install it to the corresponding position of the work object. This process requires the operator to return to the safe zone of the building to operate. more cumbersome
