Problems solved by technology

For vehicles with special requirements, the truck crane leveling method can no longer meet the stability requirements of the support and the time index requirements for rapid leveling
The use of electro-hydraulic proportional valves will cause the problem of hydraulic oil temperature rise due to throttling power loss and the price and cost of electro-hydraulic proportional valves

Abstract

The invention relates to a hydraulic support leveling system for a vehicle. The hydraulic support leveling system comprises a hydraulic oil tank, a high-flow hydraulic oil pump, a manual hydraulic oilpump, a low-flow hydraulic oil pump, a front left oil cylinder, a front right oil cylinder, a rear left oil cylinder, and a rear right oil cylinder; and the front left oil cylinder, the front right oil cylinder, the rear left oil cylinder, and the rear right oil cylinder are installed on a vehicle body beam. The hydraulic support leveling system further comprises a hydraulic valve integrated component which is provided with a first magnetic valve, a second magnetic valve, a front left oil cylinder control valve, a front right oil cylinder control valve, a rear left oil cylinder control valve,a rear right oil cylinder control valve; the high-flow hydraulic oil pump, the manual hydraulic oil pump, and the low-flow hydraulic oil pump separately communicate with the oil inlets P of the firstmagnetic valve and the second magnetic valve through one-way valves; the front left oil cylinder is connected with the front left oil cylinder control valve in a communicating mode; the front right oil cylinder is connected with the front right oil cylinder control valve in a communicating mode; the rear left oil cylinder is connected with the rear left oil cylinder control valve in a communicating mode; and the rear right oil cylinder is connected with the rear right oil cylinder control valve in a communicating mode. The hydraulic support leveling system for the vehicle can quickly and stably level the vehicle and a carrying device to a specified high precision index to enable the carrying device to work normally.

Description

technical field [0001] The invention relates to a special-purpose vehicle, in particular to a hydraulic support and leveling system for the vehicle, especially a device for supporting and leveling equipment installed on the vehicle. Background technique [0002] For special vehicles, in addition to the mass of the vehicle itself, equipment with various functions needs to be installed on the vehicle. In general, the load of equipment installed on the vehicle is greater than the mass of the vehicle chassis itself. For some additional special equipment, it needs to be supported and leveled on the vehicle before the equipment can work normally. Most of the existing special vehicles adopt the support leveling method of upright oil cylinder, manual reversing valve or electro-hydraulic proportional valve, such as truck cranes, which belong to the upright support oil cylinder and manual reversing valve support leveling method. For vehicles with special requirements, the truck crane...
