A track dual power work vehicle

Abstract

The invention relates to the technical field of rail dual-power work vehicles, in particular to a rail dual-power work vehicle, comprising a rail wheel body, a rail, a frame, a first braking device and a second braking device; the frame is fixedly installed on the rail On one side of the wheel body, the first braking device is fixedly installed on the end of the frame in a vertical state; the second braking device is fixedly installed on one side of the frame, the second braking device is located directly above the track, and the second braking device is fixedly installed on one side of the frame. The output ends of the two braking devices are arranged towards the top of the track, the frame, the first braking device and the second braking device are respectively provided with two groups, and the two groups of racks, the first braking device and the second braking device are mirror images The state is set on both sides of the rail wheel body. After the work vehicle stops to the working area, the application can sequentially limit and tighten the wheels of the work vehicle and between the carriage and the track, so that the carriage and the guide rail are fixed. , it will not cause the carriage itself to shake easily due to external force.

[0002] At present, the railway engineering vehicles powered by diesel engines are seriously wasting energy.

Through the research on energy consumption under the driving conditions of the whole vehicle, the results show that: the engine consumes more fuel during idling, accounting for 17-44% of the total fuel consumption, the efficiency is low, and the peak efficiency of the engine is not fully utilized. Since the work vehicle does not stop at a station, it will stop and go according to different working areas, which will increase unnecessary fuel consumption. In addition, when the internal combustion work vehicle is working in the tunnel, the exhaust gas emitted by the engine is not easy to diffuse, which is harmful to the construction work. The health of personnel will also cause great harm. For this problem, a kind of oil-electric hybrid track dual-power work vehicle has been introduced. When the work vehicle enters the tunnel section for operation, the work vehicle will use electricity as power to As the power source of the work vehicle, it solves the technical problem that the diesel engine will emit toxic exhaust gas when working in a confined space, which will endanger the health of the staff;

[0003] When the work vehicle travels from one operation point to the next operation point, it will repeatedly use the brakes. The existing parking method of the rail work vehicle is to rely on the brake system of the work vehicle to lock the wheels, and then use the wheel and the guide rail to lock the wheels. The friction force will stop the trolley on the guide rail. When the work vehicle stops, the brakes will release the wheels, and then rely on the weight of the body itself to hover on the guide rail. The weight can hover on the guide rail stably. The traditional operation vehicle is small in size and light in weight, and the body is equipped with operating equipment. When the operation vehicle stops to the corresponding operation area, the staff is manipulating the equipment on the operation vehicle to carry out the operation. At this time, because the reciprocating swing of the equipment is likely to drive the body to move forward or backward in a small range on the guide rail, a small shake will affect the final result of the operation when performing precision operations. If the body is moving at the moment, The staff's center of gravity is slightly unstable, which may also cause the operator to fall from the work vehicle, and the risk factor is high;
