Pantograph traction device of track train

Abstract

The invention relates to a pantograph traction device of a track train. The pantograph traction device of the track train comprises a mounting base, a wire winding wheel is rotatably assembled on themounting base and provided with a spiral wire winding groove, the side, at the wire winding wheel, of the mounting base is provided with a wire discharging device, the wire discharging device is provided with a wire discharging channel and connected with a wire discharging device driving device, and the wire discharging device driving device is provided with a power input shaft; the mounting baseis provided with a speed reduction mechanism, the speed reduction mechanism is provided with an output shaft, and when the wire winding wheel rotates within a full number of turns, the rotation angleof the output shaft is always less than 360 degrees; the mounting base is further provided with a rotary potentiometer, the output shaft of the speed reduction mechanism, a power input shaft of the wire discharging device driving device and an input shaft of the rotary potentiometer are connected through transmission pieces to achieve the constant-angular-velocity and synchronous movement of the output shaft of the speed reduction mechanism, the wire discharging device and the rotary potentiometer. According to the pantograph traction device of the track train, a traction line can accurately stay at a detection position, and the accuracy of measuring the pantograph relaxation force is improved.

Description

technical field [0001] The invention relates to a rail train pantograph pulling device. Background technique [0002] At present, with the rapid increase in the mileage of my country's ordinary railways, high-speed railways, and urban rail lines, the number of rail trains has grown rapidly. As an important part of the electric locomotive, the pantograph is used to transmit the electric energy transmitted by the catenary to the traction power of the locomotive and other battery modules. When working, the pantograph will maintain a certain distance with the catenary under the action of pressure such as air pressure. Pressure to ensure that the carbon slider of the pantograph is in good contact with the catenary. Therefore, the tension force of the pantograph is one of the important parameters to measure whether the pantograph works normally or not. At present, the known pantograph force-measuring devices for rail trains are mainly hand-held force-measuring devices, which gen...
