Description

Device for preventing trolley locomotive track contact failure

Technical Field

Background

The trolley locomotive is widely used under a mine, and the working principle of the trolley locomotive is to obtain electric energy from a traction line through a pantograph. When the electric locomotive is running, the pantograph slides along the traction wire. The power supply mode of the trolley locomotive is that the positive pole of a direct current power supply is connected with a traction wire lead through a power supply cable, a contact point in the period becomes a power supply point, the negative pole of the direct current power supply is connected with a track through the trolley locomotive, and the corresponding contact point is called as a return point. When the electric traction device works, the upper part of the electric locomotive running along the track is contacted with the traction line by the pantograph to obtain electric energy, and the lower part of the electric locomotive is contacted with the track by wheels to form a loop so as to enable the traction motor to work, thereby enabling the electric locomotive to draw the mine car to run. In the installation process of the motor vehicle track, a gap of 5mm can exist between the track and the track, and the track are connected by adopting a track clamping plate. At present, when the electric locomotive passes through the rail connection part, the rail clamp plate is communicated with current between two adjacent sections of rails, but due to the fact that the rail clamp plate is connected with the rails through bolts, gaps exist between bolt holes and bolts sometimes, current is broken, circuit contact is poor when the electric locomotive runs, and normal running of the electric locomotive is affected.
