The invention aims to provide a mining tractor capable of driving across tracks to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: the mining tractor capable of running across the track comprises a tractor body, a driving device and a wheel changing device, wherein two hydraulic cylinders are arranged on two sides of the bottom of the tractor body respectively, the driving device comprises a motor, a driving shaft and a first belt, the motor is installed in the middle of the bottom of the tractor body and is connected with the driving shaft through the first belt, two ends of the driving shaft are connected with wheel axles on track wheels and ground wheels through second belts, the wheel changing device comprises track wheels, ground wheels and a fixed shaft, the track wheels and the ground wheels are fixed on the fixed shaft through connecting rods, and the fixed shaft is connected with the hydraulic cylinders. And a joint bearing is arranged at the joint of the hydraulic cylinder and the fixed shaft. The length of the connecting rods of the rail wheels and the ground wheels is the same, and an included angle between the rail wheels and the ground wheels is an acute angle. The tail end of the fixed shaft extends to the outer side of the vehicle body, and the tail end of the fixed shaft is connected with a ground wheel.
Preferably, the ground wheels are larger than the rail wheels.
Compared with the prior art, the invention has the beneficial effects that: the fixed shaft can be driven to rotate by controlling the stretching action of the hydraulic cylinder on the fixed shaft, so that the conversion between the rail wheels and the ground wheels is realized, the defects that the conventional mining tractor can only run on the rail and cannot independently run on the ground are overcome, and the working efficiency of the mining tractor is improved.
