Self-adaptive anti-falling device and current collector thereof

Abstract

The invention discloses a self-adaptive anti-falling device and a current collector thereof.The self-adaptive anti-falling device is connected between a sliding shoe and a swing rod base and comprises a connecting base arranged on the sliding shoe and a mounting base arranged on the swing rod base, the connecting base and the mounting base are connected in an embedded mode, and a gap exists between the connecting base and the mounting base at the embedded position; and elastic fillers are filled in the gaps, so that the connecting seat can swing relative to the mounting seat around an axis parallel to the arrangement direction of the sliding shoes when being stressed, and can float relative to the mounting seat along the direction vertical to the swinging axis. The self-adaptive anti-falling device has the advantages of simplicity, practicability, high connection strength, swing allowance, capability of making up contact errors between the sliding shoes and the power supply rail and the like. The current collector using the self-adaptive anti-falling device has the advantages of being stable in electricity taking performance, prolonging the service life of the sliding shoes, prolonging the maintenance cycle of a vehicle and the like.

Description

technical field [0001] The invention relates to the field of current receivers, in particular to an adaptive anti-dropping device and a current receiver thereof. Background technique [0002] The current collector is a device that is installed on the rail train and dynamically draws current by contacting the rigid power supply rail to supply power to the train. The current collector needs to keep in contact with the power supply rail during the current extraction process, but the installation position error of the current collector, the manufacturing error of the power supply rail, assembly error, wear and other factors may easily cause the current collector slipper and the power supply rail surface to be non-parallel to each other. The problem occurs, which not only causes poor contact and unstable power supply of the current receiver, but also causes eccentric wear of the current receiver slipper, reduces the service life of the slipper, increases economic losses, and shor...

AI Technical Summary

Problems solved by technology

The current receiver needs to keep in contact with the power supply rail during the process of taking current, but factors such as the installation position error of the current receiver, the manufacturing error of the power supply rail, assembly error, wear and other factors are likely to cause the sliding shoe of the current receiver and the surface of the power supply rail to be non-parallel to each other The occurrence of the problem not only causes poor contact and makes the power supply of the current receiver unstable, but also causes partial wear of the slipper shoe of the current collector, which reduces the service life of the slipper shoe, increases economic losses, and shortens the vehicle maintenance cycle

[0003] The Chinese patent with the application number 201721087263.6 discloses a double-swing bar insulated current collector, which is equipped with a sliding shoe buffer device, but the buffer device is made of rubber or polyurethane, etc., and this type of buffer device itself has the risk of aging. At the same time, under the action of a large external force, the buffer device will break from the middle, causing the sliding shoe to fall off, easily causing damage and failure of the current collector, and even causing damage to the car body and lines, which poses a large safety hazard
