Background technique

Mine vehicles are an indispensable device for transporting personnel and materials in mines. The current mine tractors can only run on special tracks and cannot be switched to work on the ground, and their functions are relatively single.

Contents of the invention

The purpose of the present invention is to provide a mining tractor that can travel across tracks to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the present invention provides the following technical solutions: a mining tractor that can travel across the track, including a vehicle body, a driving device and a wheel changing device, two hydraulic cylinders are respectively arranged on both sides of the bottom of the vehicle body, and the driving The device includes a motor, a drive shaft, and a first belt, the motor is installed in the middle of the bottom of the vehicle body, and the motor is connected to the drive shaft through the first belt, and both ends of the drive shaft are connected to the track wheels and the ground wheels through the second belt The wheel shaft on the ground is connected, and the wheel changing device includes a track wheel, a ground wheel and a fixed shaft, and the track wheel and the ground wheel are fixed on the fixed shaft through a connecting rod, and the fixed shaft is connected with a hydraulic cylinder.

Preferably, a joint bearing is provided at the joint between the hydraulic cylinder and the fixed shaft.

Preferably, the connecting rods of the rail wheel and the ground wheel have the same length, and the angle between them is an acute angle.

Preferably, the end of the fixed shaft extends to the outside of the vehicle body, and the end of the fixed shaft is connected to the ground wheels.

Preferably, said ground wheels are larger than rail wheels.

Compared with the prior art, the beneficial effect of the present invention is that the fixed shaft can be driven to rotate by controlling the stretching effect of the hydraulic cylinder on the fixed shaft, thereby realizing the conversion between the rail wheel and the ground wheel, and overcoming the conventional mine The tractor can only run on the track, and cannot work alone on the ground, thereby improving the working efficiency of the mining vehicle.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Fig. 1-2, an embodiment provided by the present invention: a mining tractor capable of traveling across the track, including a vehicle body 1, a driving device 2 and a wheel changing device 3, and the two sides of the bottom of the vehicle body 1 are respectively provided with Two hydraulic cylinders 4, the driving device 2 includes a motor 21, a drive shaft 22, and a first belt 23, the motor 21 is installed in the middle of the bottom of the vehicle body 1, and the motor 21 is connected to the drive shaft 22 through the first belt 23, Both ends of the driving shaft 22 are connected with the wheel shaft 6 on the rail wheel 31 and the ground wheel 32 through the second belt 5, and the wheel changing device 3 includes the rail wheel 31, the ground wheel 32 and the fixed shaft 33, so The ground wheels 32 are larger than the track wheels 31, the length of the connecting rod 7 of the track wheels 31 and the ground wheels 32 is the same, and the angle between the two is an acute angle, preventing unused wheels from colliding with the vehicle body 1, and the track Wheel 31 and ground wheel 32 are fixed on the fixed shaft 33 by connecting rod 7, and the end of described fixed shaft 33 extends to the outside of vehicle body 1, and the end of fixed shaft 33 connects ground wheel 32, prevents tractor from switching to ground or When switching from the ground to the track, the ground wheel 32 rubs against the track, and the fixed shaft 33 is connected to the hydraulic cylinder 4, and the connection between the hydraulic cylinder 4 and the fixed shaft 33 is provided with a joint bearing 8, which is used to change the position of the fixed 33 shaft. turn direction.

Working principle: By controlling the stretching effect of the hydraulic cylinder 1 on the fixed shaft 33, the fixed shaft 33 can be driven to rotate, and the conversion between the track wheels 31 fixed on the fixed shaft 33 and the ground wheels 32, when the tractor switches from the track When reaching the ground, when the hydraulic cylinder 4 pushes the fixed shaft 33 to rotate clockwise, the rail wheel 31 leaves the track, and the ground wheel 32 touches the ground, and the tractor can run on the ground. When the tractor switches from the ground, the hydraulic cylinder 4 Pull the fixed shaft 33 to rotate counterclockwise, the rail wheel 31 falls on the track, and the ground wheel 32 leaves the ground, and the tractor can travel on the track.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or perform equivalent replacements for some of the technical features. Within the spirit and principles of the present invention, any modifications, equivalent replacements, improvements, etc., shall be included in the protection scope of the present invention.
