Description
Technical field
The present invention relates to a kind of mining electric locomotive, be specifically related to a kind of mining electric locomotive traction drive, belong to mining conveying equipment technical field.
Background technology
The development tendency of mining electric locomotive is high speed and heavy traction, therefore locomotive is needed to possess larger shp, due to the restriction by line condition, the number of axle of single-unit locomotive and axle heavily possess certain number range, along with locomotive power constantly increases, the ratio of locomotive weight and power is more and more little, and this just requires that the adhesion weight making full use of locomotive plays larger wheel shaft tractive force, anti-stopping wheel idle running.
Underground Mine electric locomotive many employings diaxon mining electric locomotive type of drive, what diaxon mining electric locomotive type of drive great majority adopted is the two individual drive axle mode of double-motor, and namely a motor drives one to take turns not linking.This kind of driving system is simple to operate, and the normal run time behaviour of mechanism is reliable, and when after one of them motor damage, another motor can also continue to run; But because electric locomotive design axle is heavy not etc., or when there is axle weight transfer in operational process, or the rotating speed of two independently motors inconsistent time, double-motor independence mode of traction then cannot balance motor output torque, the sticky heavy degree of utilization of electric locomotive is caused to reduce, tractive force reduces, and electric locomotive carrying capacity declines; And traditional double-motor mining electric locomotive is structurally all larger, the process that the electric locomotive of more than 8t model transports down-hole to by vertical shaft is all more difficult.
Summary of the invention
For solving the problem, the invention provides a kind of mining electric locomotive traction drive, the adhesion weight of locomotive can be made full use of, improve electric locomotive carrying capacity, ensure that the structure of electric locomotive is compacter simultaneously.
To achieve these goals, a kind of mining electric locomotive traction drive, comprise front-wheel to, trailing wheel to, front wheel decelerator, rear wheel decelerator and traction electric machine, front wheel decelerator and front-wheel are to being connected, rear wheel decelerator and trailing wheel are to being connected, described traction electric machine is arranged between front wheel decelerator and rear wheel decelerator, and the front end output shaft of traction electric machine is connected with front wheel decelerator by front-wheel coupler, and the rear end output shaft of traction electric machine is connected with rear wheel decelerator by trailing wheel coupler.
Traction electric machine energising starts, the output shaft of rear and front end rotates with identical rotating speed, the front end output shaft of traction electric machine drives front-wheel reducer input shaft to rotate by front-wheel coupler, traction electric machine rear end output shaft drives trailing wheel reducer input shaft to rotate by trailing wheel coupler, and then transmission shaft rotation at different levels in wheel decelerator before being driven by the gear pairs at different levels in front wheel decelerator, after being driven by the gear pairs at different levels in rear wheel decelerator, in wheel decelerator, transmission shaft at different levels rotates, front-wheel reducer output shaft and trailing wheel reducer output shaft drive respectively mining electric locomotive front-wheel to trailing wheel to rotation, and then roll in orbit, realize locomotive straight line moving.
Front and back end output shaft due to traction electric machine is the two ends of same axis, and rotating speed is consistent, and the speed that therefore front and back wheel is right is consistent, and two right glutinous weights of wheel just can be fully used, and play the towability of mining electric locomotive to greatest extent; And compared to double-motor traction mining electric locomotive, longitudinal size decreases the size of a motor, just can reduce the longitudinal size of electric locomotive, the process that undersized mining electric locomotive transports down-hole to by vertical shaft is just more prone to, and mining electric locomotive underground transportation is also more flexible.
Further, front-wheel coupler and trailing wheel coupler are same model coupler; Front wheel decelerator and rear wheel decelerator are same model retarder.Because front wheel decelerator is the same with structure with the reduction ratio of rear wheel decelerator, front-wheel coupler and trailing wheel coupler are the coupler of same model, therefore can ensure that the speed that front and back wheel is right is completely the same.
Further, traction electric machine is double end three phase asynchronous motor.Three phase asynchronous motor is short for run up time, and Starting mode is simple and reliable, and required cost is low.
Compact conformation of the present invention, the electric locomotive scantling of structure of same model is less, and reliable operation can give full play to the towability of mining electric locomotive, improves mining electric locomotive carrying capacity, is conducive to enhancing productivity, and reduces potential safety hazard.
