Protection cabin applied to tunnel safety protection trolley

Abstract

The invention relates to a protection cabin applied to a tunnel safety protection trolley, and relates to the technical field of safety protection. The problem that a tunnel safety protection trolleyin the prior art cannot well protect operators is solved. The protection cabin comprises a horizontal cabin plate and a vertical cabin plate which are perpendicular to each other, wherein one end of the horizontal cabin plate is connected to a supporting framework, and the other end of the horizontal cabin plate is fixedly connected with the top end of the vertical cabin plate, the bottom of the vertical cabin plate and the bottom surface of the tunnel safety protection trolley are positioned in the same horizontal plane, and a body fixing device is arranged on the side, facing to the horizontal cabin plate, of the vertical cabin plate. The tunnel safety protection trolley has the effects that a safe protection place is specially provided for operators in the tunnel safety protection trolley, so that the safety effect of the operators is improved.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a protection cabin applied to a tunnel safety protection trolley. Background technique [0002] Rockburst is a phenomenon in which the rock mass is affected by excavation and unloading, which redistributes the surrounding rock stress, produces stress concentration and strain energy accumulation near the cave wall, and then causes the surrounding rock to rupture, eject, and throw randomly in space. This phenomenon is very prominent especially in the face of deeply buried tunnels, tunnel vaults, and spandrels. As a geological disaster, rockburst can not only cause equipment loss, project failure, and delay in construction period, but also greatly threaten the life safety of construction technicians because of its suddenness, randomness, and violent nature. Therefore, in order to alleviate the threat to construction personnel and construction equipment when rockburst burs...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: when rockfall or rockburst occurs, the operator needs to run into the tunnel safety protection trolley to avoid danger, but there is no dedicated tunnel for the operator in the existing tunnel safety protection trolley. The protective places to avoid are all equipment and people hiding in the protective trolley together. In the case of distance shaking, falling rocks and rockbursts, the equipment in the tunnel protective trolley is easy to tilt, making the environment in the tunnel safety protection trolley It is relatively chaotic, which affects the operators to avoid danger. In severe cases, the equipment may injure the operators during the tilting process, which is not conducive to protecting the safety of the operators.
