Problems solved by technology

However, in the actual mining environment, when the mining vehicle is unloading, especially in the case of sticky boxes, the cab of the mining vehicle will be pressed up, causing a back-turning accident or other dangers. How to avoid the unloading process The cab is pressed up is a technical difficulty of mining dump trucks

Embodiment Construction

[0018] like figure 1 , 2 As shown in the figure, an unmanned mining vehicle lift control system includes a body attitude sensor 1, a reversing valve controller 3, a reversing valve 6, a piston rod 3, a hydraulic cylinder 4, a fuel tank 5, and a gear pump 7 and PTO 8;

[0019] The vehicle body attitude sensor 1 is located in the cab and is used to measure the attitude of the vehicle body;

[0020] The reversing valve controller 2 is located on the outside of the frame longitudinal beam, one end of which is connected to the vehicle body attitude sensor 1, and the other end is connected to the reversing valve 6, and receives the information of the vehicle body attitude sensor 1 for controlling the switch. To the working position of valve 6, the working position includes lifting and lowering;

[0021] The reversing valve 6 is located outside the longitudinal beam of the frame, and is used to receive information from the reversing valve controller 2, and based on the information...

Abstract

The present invention relates to an unmanned mining vehicle lifting control system, method and mining vehicle. The unmanned mining truck lift control system includes a body attitude sensor, a reversing valve controller, a reversing valve, a piston rod, a hydraulic cylinder, a fuel tank, a gear pump and a power take-off; the body attitude sensor is located in the cab and is used for Measure the posture of the body; the reversing valve controller is located on the outside of the longitudinal beam of the frame, one end of which is connected to the body posture sensor, and the other end is connected to the reversing valve, which receives the information of the body posture sensor and is used to control the working position of the reversing valve; The diverter valve is located on the outside of the frame rail and connects or disconnects the gear pump, hydraulic cylinder and oil tank. The present invention can use the body posture to determine whether the driver's cab is pressed up, and by changing the working position of the reversing valve, the car box can slowly fall down, and the tendency of the driver's cab to be pressed up can be suppressed, thereby improving the safety of the unmanned mining truck. Work efficiency and work safety.

Description

technical field [0001] The invention relates to the technical field of unmanned mining vehicles, in particular to an unmanned mining vehicle lifting control system, method and mining vehicle. Background technique [0002] Mining trucks are the main vehicles operating in mining areas, and are mainly used for loading, unloading and transporting earthwork, sand, and bulk materials. In recent years, due to the harsh working environment, high labor intensity and poor living conditions in mining areas, it has become more and more difficult to recruit mining truck drivers. The demand for driverless mining vehicles in the market is also getting louder. Unmanned mining vehicles can reduce the technical threshold of labor, until the problem of existing labor difficulties is completely solved, which facilitates the operation and management of mining vehicles, and improves the efficiency and safety of mining operations. However, in the actual mining environment, when the mining truck ...
