Abstract

The invention discloses an electric brush structure installed in a slide wire current collector and relates to the technical field of slide wires. The electric brush structure comprises a current collector shell and an electric brush; an electric brush fixing groove is formed in the current collector shell, a guide brush holder is fixed in the electric brush fixing groove, an opening groove is formed in one side of the guide brush holder, a constant force driving spring assembly is clamped in the opening groove, the constant force driving spring assembly comprises a constant force coil springand an L-shaped fixed support which are riveted together through rivets, the constant force coil spring is placed in a cavity of the guide brush holder, the electric brush is further arranged in the cavity of the guide brush holder in a sliding mode, the constant force coil spring contacts and abuts against the bottom surface of the electric brush, a guide sliding chute is formed in one side of the electric brush, and the guide sliding chute is in sliding fit with the head of a cylindrical end of the rivet. According to the electric brush structure in the invention, the electric brush can be well guided during telescopic motions, the electric brush is not prone to skewing and jamming, and the electric brush is not easy to wear; the constant force spring driving structure can provide balanced driving force, thereby facilitating stable and reliable power supply of the slide wire in the moving process.

Description

technical field

[0001] The invention relates to the technical field of trolley lines, in particular to a brush structure installed in a trolley line collector. Background technique

[0002] In the process of building construction, it is necessary to use the construction elevator to transport materials. The construction elevator needs to be connected to the power line to be driven. However, in the construction process, there is usually no dedicated power supply line to supply power to the construction elevator. Usually, the sliding contact is used. The line supplies power to the construction elevator. The sliding contact line is a number of conductive tracks laid in parallel along the running track of the construction elevator. The construction elevator is installed with a collector that can slide to connect the conductive track and take electricity. The sliding cooperation of the contact wires can provide uninterrupted power supply to the lifting and moving construction elev...
