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, the subway tunnel includes a tunnel body, and the tunnel body is provided with an anti-flooding door that can close the tunnel body; the busbar joint device includes the busbar left section 1, the busbar right section 2 and the use between the two For the connected connecting section 3, the flood-proof door is hinged on the inner wall of the tunnel body, the connecting section 3 is at the closing track of the flood-proof door, and the left section 1 of the busbar is fixed with a positioning plate 4, The positioning plate 4 is provided with a through 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 is provided with a support plate 5 that can abut against the right side of the busbar. The positioning structure at the lower part of section 2, the connecting section 3 is arranged on the support plate 5, one end of the connecting section 3 passes thro...

Embodiment 2

[0035] The content of the second embodiment is roughly the same as that of 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 second mounting block is provided with a first mounting hole and a second mounting hole, one end of the support plate 5 is fixed with a hinge shaft, and the first mounting hole and the second mounting hole are respectively fixed with a positioning bearing one and a positioning bearing two, so The hinge shaft is arranged between the first mounting block and the second mounting block, and the two ends of the hinge shaft are respectively fixed at the inner ring of the positioning bearing one and the inner ring of the positioning bearing two; and in the second embodiment, The lower part of the positioning plate 4 is vertically fixed with a first mounting block and a second mounting block. The first an...

Abstract

The invention provides a modified bus-bar joint device of a subway tunnel. The modified bus-bar joint device of the subway tunnel solves the technical problem that the connection section of a bus-bar joint device in an existing subway tunnel can not drop smoothly. The modified bus-bar joint device of the subway tunnel comprises a bus-bar left section, a bus-bar right section and a connection section located between the bus-bar left section and the bus-bar right section and used for connection, wherein the connection section is detachably arranged between the bus-bar left section and the bus-bar right section; a flood gate is hinged to the inner wall of a tunnel body; the connection section is located at the gate closing track of the flood gate. The modified bus-bar joint device of the subway tunnel has the advantages of saving time, being higher in efficiency, good in stability and safe in use, and the like.

Description

Technical field [0001] The invention relates to a subway tunnel, in particular to an improved bus bar joint device of the subway tunnel. Background technique [0002] With the rapid development of my country's urban rail transit construction, the form of rigid suspension catenary has been widely adopted. Rigid suspension catenary is a system composed of contact wires embedded in bus bars connected end to end. 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] In the construction of urban subway tunnels, anti-flooding doors are designed. In the special situation of war and serious water leakage, it is necessary to quickly close the anti-flooding doors and anti-flooding doors of the tunnel to ensure the safety of the tunnel and personnel. However, under the block of the busbar, the flood-proof door cannot be completely closed. Special personnel need to be sent...
