Backflow device for urban rail car vehicle flow and lifting shoe method thereof

Abstract

The invention discloses a backflow device for urban rail vehicle flow and a lifting shoe method thereof. The backflow device comprises a back plate (1), a chassis (2), a torsion spring (3), a swing arm (4) and a lock structure (5). The back plate is made of an epoxy insulating plate, and the chassis is fixedly installed on the back plate. A first bearing (17) and a second bearing (25) are suspended on the chassis, and the first bearing and the second bearing are supported and installed with a rotating shaft (12) through bearings. One end of the swing arm is provided with a pivot part, and theswing arm is pivotally mounted on the rotating shaft via the pivot part One end of the rotating shaft is provided with the locking structure capable of locking the swing arm lifting shoe state. The middle part of the rotating shaft is sleeved with the torsion spring, one end of the torsion spring is connected with the swing arm and provides a contact force to the swing arm so as to make the swingarm contact with the return rail (6), and the other end of the torsion spring is fixedly connected with the chassis. The backflow device increases the mechanical performance of the backboard material,and the backflow device is reliable in performance and convenient for operation and adjustment.

Description

technical field [0001] The invention relates to a return device for urban rail vehicles and a method for lifting shoes thereof. Background technique [0002] With the development of society, urban rail vehicles flow back through the rails, and stray currents will interfere and corrode the equipment beside the track. In order to solve the impact of the wheel-rail return on trackside equipment, urban rail vehicles can use the fourth rail return to transfer the train's current to the return rail through the return device, reducing the impact of stray current on the equipment near the track. [0003] Among the existing reflux devices, the typical one is the current collector, which receives current from the bottom or side, and transmits the power supply rail current to the train, and is mainly used for receiving current at the positive pole. [0004] The structure of the existing receiver is as follows figure 1 As shown, it mainly includes backplane 1', bottom frame 2', tensio...

Problems solved by technology

[0004] The structure of the existing receiver is as follows figure 1 As shown, it mainly includes backplane 1', bottom frame 2', tension spring 3', swing arm 4' and lock structure. The disadvantage of this product is that the backplane 1' is insulated by molding, and the mechanical properties of the material are relatively low. Low, complex lock structure, inconvenient adjustment and maintenance
