In railway transportation, in order to ensure the safety of railway operation, the railway needs to be maintained and overhauled regularly; because the railway line is long and the vehicles running on the railway cannot be controlled, maintenance personnel need to finish maintenance operation on the current section of railway in a short time, so that maintenance is required to be carried along the rail with as many maintenance equipment and parts as possible, and round trip is avoided, and therefore, in the railway maintenance process, the maintenance equipment and the parts are convenient to carry, and the transport vehicle can be used as the carrying equipment.
And because the operation time left for the overhauling staff is not much, the stay time of the overhauling staff at each overhauling point is very limited. The weight of the used material transporting vehicle is too large, and the material transporting vehicle is very difficult to control during braking. And the weight of the material mover is larger in rated carrying, and although the travelling speed is not fast, the material mover can slide on the steel rail for a certain distance even if the rolling brake of the wheels is stopped due to the component force and the inertia when the material mover brakes on the ramp. When the vehicle has been disconnected from the person's control, an immeasurable accident may occur if a person or other item is in front of the vehicle. At the moment, the sliding of the material transporting vehicle also increases the uncontrollable braking distance, so that the parking time is increased, the braking distance is further prolonged, the gap exists between the parking spot and the preset place, and the maintenance personnel also need to walk and turn back when in maintenance, so that the operation of the maintenance personnel is inconvenient, and the efficiency is further affected. The relative sliding between the wheels and the rails also causes abrasion to the wheels, reducing the service life of the wheels.
In addition, when the wheels run on the rails, static electricity is easily generated between the double rails due to friction, so that traffic signals are disturbed, safety accidents are caused, and the running speed of the material transporting vehicle cannot be too high.
Therefore, in order to solve the problems that the braking distance of the existing track material mover is too long when the track material mover is stopped, uncontrollable sliding occurs after braking, the braking distance is difficult to control, the abrasion to wheels is serious and static electricity is easy to generate, and the wheel structure for the track material mover needs to be provided.
