specific Embodiment 1

[0041] like Figure 2 to Figure 12 As shown in the figure, the steel pipe transport vehicle in the tunnel (hereinafter referred to as the transport vehicle) is used to carry the steel pipe, and transport the steel pipe in the tunnel to the place where the steel pipe has been laid for docking.

[0042] The transport vehicle includes a main beam 4, and the front and rear ends of the main beam 4 are respectively equipped with lifting and traveling wheel assemblies. The lifting and traveling wheel assemblies support the main beam 4 and drive the main beam 4 to move back and forth. Among them, the head and tail of the main beam 4 are only relative concepts. The lifting and traveling wheel assembly at one end of the main beam 4 includes a first active rubber wheel group 8, a first steel wheel group 9 and a first driven rubber wheel group 10 that can be lifted independently. The driven rubber wheel set 10 is disposed on the front and rear sides of the first steel wheel set 9 , and t...

Abstract

The invention belongs to the technical field of tunnel lining object transportation, and particularly relates to an in-tunnel steel pipe transport cart which comprises a main beam, a supporting device used for supporting a steel pipe is arranged on the main beam, and lifting walking wheel assemblies are arranged at the head end and the tail end of the main beam. The steel pipe transport vehicle in the tunnel further comprises an anti-collision alarm device, the anti-collision alarm device comprises supporting units arranged on the left side and the right side of the main beam, each supporting unit comprises an outer sleeve which is fixedly arranged on the main beam and extends left and right, and a supporting arm is slidably assembled in each outer sleeve in the left-right direction; an elastic piece used for driving the supporting arm to move away from the main beam is arranged between the supporting arm and the outer sleeve or between the supporting arm and the main beam. The anti-collision alarm device further comprises a triggering structure and an alarm which are connected, and the triggering structure is used for being triggered when the steel pipe transport vehicle in the tunnel deflects and the supporting arm on one side is pushed to the set position by the pipe wall towards the main beam and controlling the alarm to work. The lifting walking wheel assembly is provided with a steering structure and / or a transverse moving structure.

Description

technical field [0001] The invention belongs to the technical field of tunnel lining transportation, and in particular relates to a steel pipe transportation vehicle in a tunnel. Background technique [0002] Shield machine construction method has been more and more widely used in the construction of rainwater, water supply, sewage, power tunnels, and comprehensive pipe corridors in municipal engineering. like figure 1 As shown in the figure, after the shield construction is completed, many tunnels such as water diversion and sewage will use concrete segment 1 as the outer lining, add steel pipe 2 as the inner lining, and use concrete in the annular space 3 between the inner lining and the outer lining. filling. [0003] In order to lay the steel pipe 2 in the concrete segment 1, it is necessary to transport the steel pipe 2 to the tunnel with a steel pipe transport trolley. However, the difference between the diameter of the steel pipe 2 to be transported and the inner d...
