Description

Technical Field

[0001] The utility model relates to the technical field of mining area transportation equipment, in particular to a mining truck. Background Art

[0002] At present, mining trucks are widely used in open-pit mine earthwork stripping projects. Because the roads in the mining area are complex, the slope is steep, the road surface is mostly mud and stone, and the heavy trucks are heavy-loaded, when the vehicles are transported, the heavy trucks need to use brake water to cool the friction plates (brake pads) when going downhill to reduce the damage of the friction plates due to excessive temperature. Existing mining trucks generally include a mobile chassis, a front vehicle that can be flipped forward at the front of the mobile chassis, and a car box that can be flipped backward to unload at the rear of the mobile chassis. A water tank is arranged on the mobile chassis, and the water tank supplies water to the brake pads of each wheel through a pipeline for cooling. However, on the one hand, the existing water tank is generally arranged under the mobile chassis or on the mobile chassis between the front vehicle and the car box. Due to the limitation of the installation space, the water tank cannot be set very large, and it is difficult to meet the long-distance cooling requirements; on the other hand, the water in the water tank generally needs to be pumped to the brake pads, which is costly. Utility Model Content

[0031] Since the first water tank 4 is located between the front of the vehicle 2 and the vehicle box 3 and above the wheel 11, and is connected to the second water tank 6 above, the first water tank 4 is replenished with water through the second water tank 6. On the one hand, the water storage capacity is increased to meet the long-distance cooling requirements of the brake pads of the wheel 11; on the other hand, since the second water tank 6 is located above the first water tank 4 and the first water tank 4 is located above the wheel 11, water can be discharged under the action of gravity, and there is no need to set up a pump, thereby reducing costs.

The high-level sensor 42 and the low-level sensor 43 are both used to detect the water level in the first water tank 4. When the water level reaches a specified high level, the high-level sensor 42 closes the water supply valve 71 through information transmission. When the water level reaches a specified low level, the low-level sensor 43 opens the water supply valve 71 through information transmission, thereby maintaining the water level in the first water tank 4 within a predetermined range, so that the water output of each water outlet end of the water outlet pipeline 5 is not too large or too small. The high-level sensor 42, the low-level sensor 43 and the water supply valve 71 are all conventional commercially available parts, and the connection and matching relationship between them does not need to involve a certain degree of improvement, and the conventional connection and matching of the original structure can be used.

[0041] Furthermore, in this embodiment, a control module 9 is provided in the vehicle head 2, and the high-level sensor 42, the low-level sensor 43, the water supply valve 71 and the water outlet valve 41 are all connected to the control module 9 by signals. The high-level sensor 42 and the low-level sensor 43 send signals to the control module 9, and the control module 9 adjusts the switch state of the water supply valve 71 according to the received signals, and can adjust the open and closed state of the water outlet valve 41. The control module 9, the high-level sensor 42, the low-level sensor 43, the water supply valve 71 and the water outlet valve 41 are all conventional commercially available parts, and the connection and matching relationship between them does not need to involve any degree of improvement, and the conventional connection and matching of the original structure can be used.
