Problems solved by technology

[0006] However, in actual use, the closing force of the anti-flooding door may not be able to break the wire rope. At the same time, due to the installation of too many pulleys, the wire rope is easy to get stuck, resulting in the inability of the moving joint to move, which leads to the failure of the connecting section to fall smoothly.

Embodiment 1

[0028] Such as figure 1 , figure 2 with image 3 As shown, a subway tunnel with an improved structure includes a tunnel body, and a bus bar structure for supplying power to trains and an anti-flooding door capable of closing the tunnel body are arranged in the tunnel body, and the bus bar structure includes a bus bar The left section 1, the right section 2 of the busbar and the connection section 3 between them for connection, the flood prevention door is hinged on the inner wall of the tunnel body, and the connection section 3 is at the closing track of the flood prevention door , the left section 1 of the busbar is fixed with a positioning plate 4, the positioning plate 4 is provided with a perforation hole, the lower part of the positioning plate 4 is hinged with a support plate 5, and the other end of the support plate 5 There is a positioning structure that enables the end of the support plate 5 to abut against the lower part of the right section 2 of the bus bar. The ...

Embodiment 2

[0036] The content in the second embodiment is roughly the same as that in the first embodiment, the difference is that the lower part of the positioning plate 4 in the first embodiment is vertically fixed with a mounting block 1 and a mounting block 2, and the mounting block 1 and the mounting block 2 Mounting hole 1 and mounting hole 2 are respectively opened on the mounting block 2. One end of the support plate 5 is fixed with a hinged shaft, and the mounting hole 1 and mounting hole 2 are respectively fixed with a positioning bearing 1 and a positioning bearing 2. The hinged shaft described above is arranged between the mounting block 1 and the mounting block 2, and the two ends of the hinged shaft are respectively fixed on the inner ring of the positioning bearing 1 and the inner ring of the positioning bearing 2; while in the second embodiment, The lower part of the positioning plate 4 is vertically fixed with a mounting block 1 and a mounting block 2, and the mounting bl...

Abstract

The invention provides a subway tunnel which solves the technical problems that a submerging prevention door in an existing subway tunnel can not be closed, and connecting sections can not fall smoothly. The subway tunnel comprises a tunnel body, a busbar structure used for supplying power for trains and a submerging prevention door capable of closing the tunnel. The tunnel body and the busbar structure are arranged in the tunnel body, the busbar structure comprises a busbar left section, a busbar right section, and a connecting section, wherein the connecting section is arranged between the busbar left section and the busbar right section and used for connection, the connecting section is detachably arranged between the busbar left section and the busbar right section, the submerging prevention door is hinged to the inner wall of the tunnel body, and the connecting section is located at the closing track of the submerging prevention door. The subway tunnel has the advantages that time is saved, efficiency is higher, stability is good, and using is safer.

Description

technical field [0001] The invention relates to a subway tunnel, in particular to a subway tunnel with an improved structure. Background technique [0002] With the rapid development of my country's urban rail transit construction, the form of rigid suspension catenary is widely used. Rigid suspension catenary is a system composed of catenary wires embedded in head-to-tail busbars. It is an important equipment for power supply of electrified railway locomotives and rail transit vehicles. Its quality directly affects the operation of locomotives. [0003] Anti-flood doors are designed in the construction of urban subway tunnels. In the event of war and serious water leakage, it is necessary to quickly close the anti-flood doors and anti-flood doors of the tunnel to ensure the safety of the tunnel and personnel. However, under the blockage of the busbar, the anti-flood door cannot be completely closed, and special personnel need to be sent into the tunnel to remove a section ...
