Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mine dump truck, especially to a motor mud blocking structure of range extended mine dump truck and mine dump truck. BACKGROUND

[0002] In recent years, with the rapid progress of science and technology and the increasing environmental awareness, the trend of large-scale and intelligentization of mine vehicles is becoming more and more obvious, which has become an important force to promote the efficiency and sustainability of mining production. Under this background, new energy mine dump trucks gradually occupy a place in the mine truck market due to their environmental protection and energy saving characteristics. However, although the pure electric drive system has shown great potential in many fields, due to the working characteristics of mine trucks such as heavy load, long time running and operation in complex and changeable mine environment, the pure electric drive system often fails to meet its stringent working requirements. Therefore, the range extended mine truck has shown unique competitiveness in mine transportation due to its advantages of using clean energy and ensuring the endurance of the range extender.

[0003] However, the range extended mine truck also faces a series of challenges in actual operation, among which the problem of low position of the driving motor outlet is particularly prominent. Because the mine environment is usually harsh, the road is rugged and uneven, and the wheels are easy to raise a large amount of sand during driving. When these sand splashes into the low-position driving motor outlet, the high-voltage line is easy to be covered, which not only affects the power transmission efficiency of the vehicle, but also may cause serious faults such as circuit short circuit and insulation performance decline, thereby affecting the normal operation and operation safety of the mine truck. SUMMARY

[0004] The motor mud blocking structure of the range extended mine dump truck provided by the application is used to solve the technical problem that the high-voltage line of the motor outlet is easy to be covered with sand. The application also provides a mine dump truck.

[0005] The first aspect of the application provides a motor mud blocking structure of a range extended mine dump truck, comprising:

[0006] The guard plate is connected to the vehicle frame, one side of the guard plate is adjacent to the suspension, and the other side of the guard plate is adjacent to the battery box, and the left and right sides of the guard plate have bending edges extending outward from the vehicle frame.

[0007] The reinforcing ribs are arranged vertically, the reinforcing ribs are connected to the surface of the guard plate, and the reinforcing ribs are arranged horizontally and spaced apart.

[0008] The beneficial effects of the above embodiment are that the gap between the suspension and the battery box is closed by the guard plate, so that the mud thrown by the wheels is prevented from being thrown onto the high-voltage line of the motor outlet through the gap between the suspension and the battery box, and the bending edge and the reinforcing rib can improve the structural strength of the guard plate, thereby improving the anti-deformation ability of the guard plate in harsh working conditions.

[0009] On the basis of the above embodiment, the embodiments of the present application can also be improved as follows:

[0010] In one of the embodiments of the present application: the guard plate is provided with a notch at the side of the suspension, and the notch structure is matched with the suspension structure. The beneficial effect of this step is that the notch structure avoids interference between the guard plate and the suspension.

[0011] In one of the embodiments of the present application: the lower edge of the guard plate is not higher than the center height of the wheel. The beneficial effect of this step is that the guard plate can better block the mud thrown by the wheels.

[0012] In one of the embodiments of the present application: the reinforcing rib has two. The beneficial effect of this step is that the two reinforcing ribs improve the anti-deformation ability of the guard plate.

[0013] In one of the embodiments of the present application: the reinforcing rib and the guard plate form a triangular reinforcing structure. The beneficial effect of this step is that the triangular reinforcing structure improves the anti-deformation ability of the guard plate.

[0014] The second aspect of the present application provides a mine dump truck comprising the motor mud-proof structure. BRIEF DESCRIPTION OF DRAWINGS
