Description

Technical Field

[0001] The utility model specifically relates to a multi-level sliding contact cable structure for rail transportation. Background Art

[0002] In rail transit systems, busbar cables play a vital role. Busbar cable systems usually include busbar conductive rails, current collectors, power supply equipment and control systems, etc., which are used to provide power to trams, trains or subway vehicles. These cables are usually installed on the top of the track or subway tunnel to transmit power to the moving vehicles.

[0003] When the existing multi-level busbar cables are installed and used, the cable tracks are mostly suspended and installed by suspension clamps, but the clamping grooves of the suspension clamps are usually fixed. This results in the need to select clamping grooves with the same number of cable tracks when installing cable tracks of different levels. When the number does not match, it is very easy to cause the cable tracks to be scrapped and unusable, with poor versatility. In addition, the number of cable tracks is relatively constant, resulting in the inability to combine different numbers of cable tracks according to actual needs and assemble a suitable number of suspension clamping grooves for lifting and use. For this reason, we propose a multi-level busbar cable structure for rail transit. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-level sliding contact cable structure for rail transit, so as to solve the problem in the above-mentioned background technology that the number of cable tracks and suspension clamps is relatively fixed, which makes it inconvenient to assemble different numbers of cable tracks and appropriate numbers of suspension clamps for hoisting according to actual needs.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a multi-level busbar cable structure for rail transit, comprising:

[0009] The connecting screw is rotatably mounted on the lower end of the inner side of the suspension assembly, and the lower end of the connecting screw is threadably matched with the positioning assembly to fix two adjacent cable tracks.

[0010] Preferably, an aluminum guide rail is provided inside the cable track, and an insulating sleeve is provided on the outer surface of the aluminum guide rail.

[0012] Preferably, the connecting plate is rectangular, and a plurality of the protrusions are evenly distributed along a long side of the connecting plate.

[0013] Preferably, the positioning assembly comprises a positioning column, a ring sleeve and a positioning hole, the positioning column and the ring sleeve are symmetrically arranged on two side walls of the cable track, and the positioning column is provided with a positioning hole, and the positioning hole passes through the upper surface of the ring sleeve.

[0014] Preferably, the side wall of the positioning column protrudes outward to form a guide protrusion, and the inner side wall of the ring sleeve is provided with a guide groove corresponding to the guide protrusion.

[0015] Preferably, the positioning column is cylindrical, and a rubber pad is sleeved on one end of the outer surface of the positioning column.

[0016] Preferably, a rotation groove is provided at the upper end of the outer surface of the connecting screw along its circumference, and the connecting screw and the suspension assembly are rotationally matched through the rotation groove.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] This patent is provided with a positioning component, a suspension component and a connecting screw to avoid the shape of the suspension clamp being relatively fixed.
