A kind of anti-collision device for earth moving vehicle of tunnel boring device and tunnel boring device

Abstract

The application relates to an anti-collision device for an earth-moving vehicle of a tunnel boring device, comprising an anti-collision beam arranged on the inner wall of the tunnel boring device, a support rod arranged on the anti-collision beam, and a buffer device arranged on the anti-collision beam. One end of the rod is fixed on the anti-collision beam, and the other end is fixed on the inner wall of the tunnel driving device; The buffer rod and the buffer plate arranged on the buffer rod; the casing is located at one end of the anti-collision beam away from the driving direction of the tunnel boring device, the casing is perpendicular to the anti-collision beam, the compression spring is in contact with the anti-collision beam, and the buffer rod is connected to the compression spring abutting, the buffer plate is fixedly connected with at least two buffer rods; the sleeve is provided with a limit ring, the buffer rod is provided with a limit plate, the limit plate is in contact with the compression spring, and the limit ring is used to limit the limit plate. position to prevent the buffer rod from coming out of the casing. The present application improves the construction safety of the workers in the tunnel boring device.

Description

technical field [0001] The present application relates to the field of tunnel construction safety, and in particular, to an anti-collision device for an earth-moving vehicle of a tunnel boring device and a tunnel boring device. Background technique [0002] A tunnel boring device, also known as a shield machine, is a tunnel boring machine that uses a shield method. The construction method of the shield is that the tunnel boring machine builds (lays) the "shield" (referring to the supporting segment) of the tunnel while it is excavating, which is different from the open construction method. [0003] In the process of soil drilling and excavation of the tunnel boring device, the earth moving vehicle needs to be used to transfer the soil excavated by the tunnel boring device, so as to continuously carry out the tunnel excavation work. When the earth moving vehicle is reversed inside the tunnel boring device , the earth-moving vehicle sometimes fails to brake, which causes the ...

Problems solved by technology

[0003] In the process of drilling and excavating the tunnel boring device, it is necessary to use an earth truck to transfer the excavated soil from the tunnel boring device, so as to continuously excavate the tunnel. When the earth truck is reversing inside the tunnel boring device , the earth-moving vehicle sometimes fails to brake, causing the earth-moving vehicle to crash into the position of the front-end splicing segment of the tunnel boring device, threatening the life safety of the staff
