Technical Field

The invention relates to the technical field of electric flatcars, in particular to a rail-guided electric flatcar.

Background

The electric flat car, also known as electric flat car, loop wheel machine, cross car, electric rail car, ground climbing car, etc., it is a rail type electric transport vehicle in the factory, it is a rail type transport vehicle at first, need to lay the orbit on the ground, the orbit is generally the I-shaped profile contact rail; the electric driven vehicle runs automatically under the drive of a motor reducer, and is a flat car, the table top is flat and has no carriage cover, and the car body can be non-planar but has no carriage cover under special conditions, and has no steering wheel and only has forward and backward directions.

The wheel of the existing rail electric flat car is mainly installed through a fastener, so that the wheel is inconvenient to disassemble and overhaul, the distance between guide rails is difficult to adjust, and once the installation error is large, the electric flat car is difficult to smoothly install on the guide rails.
