Rail transit beam high-place operation safety protection device

Abstract

The invention provides a rail transit beam high-place operation safety protection device which comprises a rail beam erected on a pier, a plurality of protection units and a protection net, wherein the protection units are arranged on the rail beam at intervals, and the protection net is arranged in the area between the adjacent protection units on the side face of the rail beam. The protection unit comprises two locking mechanisms and a safety net fixing mechanism; the two locking mechanisms are oppositely arranged on the two sides of the horizontal extending direction of the rail beam in a spaced mode, abut against the outer surface of the rail beam and are detachably connected with the rail beam. The safety net fixing mechanisms are fixedly connected with the two locking mechanisms respectively, the parts, exceeding the width of the rail beam, of the safety net fixing mechanisms extend upwards in the direction away from the upper surface of the rail beam to form hanging parts of theprotection net, and the two horizontally-extending ends of the protection net are hung on the hanging parts of the safety net fixing mechanisms of the adjacent protection units respectively.

Description

technical field [0001] The invention relates to the technical field of safety protection equipment for high-altitude construction of bridges, in particular to a safety protection device for high-altitude operation of rail transit beams. Background technique [0002] One of the biggest characteristics of bridge construction is that the workload of high-altitude operations is large, there are many types of work, and the operating conditions are complex and dangerous. Therefore, high-altitude operations are an important part of bridge construction safety management. According to the national standard for the classification of work at heights, any operation at a height where the fall height reference plane is 2m or more may fall is called work at heights. [0003] The construction conditions of outdoor rail transit beams are complex and the weather conditions are changeable. Safety belts, safety nets, guardrails and other protective measures must be taken during construction on ...

AI Technical Summary

Problems solved by technology

[0003] The construction conditions of outdoor rail transit beams are complex and the weather conditions are changeable. Safety belts, safety nets, guardrails and other protective measures must be taken during construction on rail transit beams. The operations on bridge piers and bridge upper parts will also involve edge operations, and When installing the safety net, it is necessary to set up a stable support; since the rail transit beam is usually prefabricated, installing temporary railings, guardrails and safety net supports on the rail transit beam inevitably installs connection components, which will damage The overall structure of rail transit beams, and with the advancement of rail transit construction progress, the protective facilities for rail transit beams working at heights need to be extended and installed, and the installation and disassembly of existing safety protection facilities are not very convenient, which increases the Beam Construction Workload
