Hydraulic leveling supporting leg retracting system and method for large-tonnage vehicle carrying platform

Abstract

According to the hydraulic leveling supporting leg retracting system of the large-tonnage vehicle carrying platform, a central processing unit is connected with a hydraulic pump station and a horizontal sensor and used for collecting horizontal angle information of the horizontal sensor, generating a leveling signal according to the horizontal angle information and sending the leveling signal to an oil pump motor of the hydraulic pump station; a hydraulic valve group is used for controlling retraction of the leveling supporting legs after receiving the retraction leveling signal; a horizontalsensor is used for detecting levelness of a vehicle-mounted platform. The method of the retracting system comprises the following steps of starting the pump motor, electrifying the retracting electromagnetic valve, quickly retracting, descending the vehicle-mounted platform, retracting the supporting legs in place, powering off the pump motor and the electromagnetic valve, and ending. The hydraulic leveling supporting leg retracting system for the large-tonnage vehicle carrying platform is advantaged in that potential safety hazards caused by inconsistent leveling leg retracting speed due to uneven platform load distribution when the leveling legs of the large-tonnage vehicle carrying platform are retracted can be solved with low cost, and safety of the system is improved.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a retracting system and a retracting method for a hydraulic leveling support leg of a large-tonnage vehicle-carrying platform. Background technique [0002] Large-tonnage vehicle-mounted platforms are used in high-tech fields such as high-mobility vehicle-mounted radars, artillery, and missile vehicles in the military, and large-scale construction machinery such as cranes, pile drivers, and aerial work machines in industry. During the use of the large-tonnage vehicle-mounted platform, it needs to be leveled before use, so that the working surface of the platform can be maintained at a relatively high level. [0003] At present, hydraulic systems are often used for leveling operations of large-tonnage vehicle-mounted platforms. The hydraulic system has the advantages of large driving force, stable operation, quick response, small size, compact structure, and convenient control. Especially...
