Abstract

The invention relates to an autonomous control system for a crane. An amplitude-variable control mechanism comprises an amplitude-variable oil cylinder, an amplitude-variable balancing valve and an amplitude-variable reversing valve; a rotary control mechanism comprises a rotary pump, an oil supplementing pump, a rotary motor, a rotary reversing valve, a rotary brake and a brake reversing valve; an amplitude-variable ball valve is arranged between the oil inlet of the amplitude-variable balancing valve and the oil outlet of the amplitude-variable reversing valve, a brake ball valve is arranged between the oil outlet of the brake reversing valve and the oil inlet of the rotary brake, and the bypass of the rotary reversing valve is connected with a rotary ball valve; when the crane is in an assisted transportation state, the amplitude-variable ball valve is in a closed state, the rotary brake is in an opening state, the brake ball valve is a closed state and the rotary ball valve is in an opening state. The autonomous control system can realize automatic rotation of a rotary table and autonomous floating of a suspension arm according to the road condition when the crane assists a traveling bogie for transportation, so as to be adaptive to the up-and-down road surface and large-angle turning, ensure the assisted transportation safety of the crane and improve the transportation convenience of the crane.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to an autonomous control system for cranes. Background technique [0002] Cranes are important equipment widely used in engineering construction. They mainly include lifting, telescopic, luffing, and slewing actions. These actions need to be completed under the drive of the hydraulic system by the lifting device, telescopic device, luffing device, and slewing device. , wherein: the lifting device mainly realizes the vertical linear motion of the hook by controlling the winch. The telescopic device mainly controls the expansion and contraction of the boom through the hydraulic cylinder and the rope row. The luffing device is mainly composed of the boom and the luffing hydraulic system. Under the action of the luffing hydraulic system, the boom rotates around the rear hinge point of the turntable to realize the lifting and lowering of the luffing. The slewing device is mainly com...
