Abstract

The invention discloses a subframe leveling hydraulic control system for leveling of a dumper. The subframe leveling hydraulic control system comprises an oil tank, a hydraulic pump, a first electromagnetic directional valve, a first piloted one-way valve, a second piloted one-way valve, a third piloted one-way valve, a first hydraulic cylinder, a second hydraulic cylinder, a third hydraulic cylinder and a fourth hydraulic cylinder. The oil tank communicates with an oil inlet of the hydraulic pump. An oil outlet of the hydraulic pump communicates with an oil inlet of the first electromagnetic directional valve through a first oil pipe. An oil return opening of the first electromagnetic directional valve communicates with the oil tank through a second oil pipe. The hydraulic control system with a subframe leveling unit has the function of leveling a subframe, and the problem that rollover safety accidents are likely to be caused by dumper tilting in the left-right direction in the unloading process of a lifting type dumper is solved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic control, in particular to a hydraulic control system for leveling a sub-frame for leveling a dump truck. Background technique [0002] When the lift type dump truck unloads the goods, due to the large sliding drop of the goods, it needs to be unloaded in a stable state. However, due to some reasons, the vehicle is often tilted left and right when it stops. The reasons are as follows: 1. During the loading or transportation process, the goods are biased to one side and cause the vehicle to tilt in the left and right directions; 2. The hardness of the parking road is different. 3. There is an inclination on the parking road itself or other objective restrictions that cause the vehicle to incline in the left and right directions after parking. If there is such an imbalance and there is no leveling system for leveling, continue to unload Cargo can easily cause vehicle rollover accidents, causing mi...
