A collector structure for rail transit vehicles

Abstract

The invention provides a current collecting structure for a rail transit vehicle, relates to the technical field of vehicle current collection, and includes a pantograph mounting seat, the pantograph mounting seat is fixed on the top of a rail vehicle, and the pantograph The surfaces on both sides of the two ends of the mounting base are respectively rotatably mounted with two No. 1 pole connecting blocks, and the two shock absorbing rods are rotatably mounted with shock absorber connecting blocks, and the inner sides of the two shock absorber connecting blocks are respectively fixedly connected. There are two shock absorbers, and a synchronous component is fixedly connected between the two synchronous component connection frames; this solution fixedly installs the pantograph mounting seat on the upper end of the rail car, and engages the synchronous gear roller through the front bow rotating ring gear, And through it, the meshing direction is reversed, and then the synchronous gear cylinder of the outer ring is meshed, so that the rotation directions of the fixed rear bow mounting plate and the front bow mounting plate are rotated in opposite directions. The degree of offset is to meet the upper cable and ensure the stability of the contact.

Description

technical field [0001] The invention relates to the technical field of vehicle current collection, in particular to a current collection structure for rail transit vehicles. Background technique [0002] In order to reduce the construction cost of tunnels, many underground railway systems will use the third rail power supply instead of overhead cables to reduce the height of tunnel drilling and save construction costs. However, there are also underground railways that use elevated cables. Their elevated cables are generally very low, close to the roof of the train, in order to reduce the height of the tunnel and save construction costs. Also because of the same reason, all subways in the world use direct current as power supply, and the required equipment is more complicated if not used, and the body and overhead cables also need higher alternating current for power supply. [0003] The current railcars all need the third track for power supply, and some places cannot build...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a current collector structure for rail transit vehicles, which solves the problem that today’s rail vehicles all need a third rail to supply power, and some places cannot To build a subway, the third track can only use floating cables to collect power through the pantograph. Because the route on the ground has many right angles, it is easy to cause the cable to break away from the contact range of the pantograph when turning, resulting in a short-term A power outage may cause a traffic accident
