Problems solved by technology

When the oil pressure suddenly increases, the pressure of the crane control system is unbalanced, which may cause the hydraulic components to fail or be damaged, resulting in oil leakage from the oil pipe, or even bursting of the oil pipe, which will seriously threaten the safety of the operation
If the hydraulic components fail or are damaged, the control system may suddenly release pressure, resulting in a safety accident of cargo falling

Embodiment Construction

[0070] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0071] Such as Figure 1 to Figure 8 As shown, a crane control system includes a hydraulic oil tank 1, a main pump assembly 2, a switch assembly 3, a slewing system 4 for driving a slewing mechanism, a main hoisting system 5 for driving a main hoisting winch, and a The auxiliary hoisting system 6 of the auxiliary hoisting winch, the luffing system 7 used to drive the luffing winch, the steadier system 8 used to drive the steadier winch, the cooling system 9 used to cool the hydraulic oil and the A control system 10 that issues action signals.

[0072] Hydraulic oil tank 1 provides hydraulic oil for the entire crane control system, main pump assembly 2 provides main hydraulic oil for the entire control system, switch assembly 3, slewing system 4, main hoisting system 5, auxiliary hoisting system 6, luffing system 7 Cooperating with t...

Abstract

The invention relates to cranes, in particular to a crane control system and control method. The control system comprises a hydraulic oil tank, a main pump assembly, a switch assembly, a rotary systemused for driving a rotary mechanism, a main lifting system used for driving a main lifting winch, an auxiliary lifting system used for driving an auxiliary lifting winch, an amplitude variation system used for driving an amplitude variation winch, a guy system used for driving a guy winch, and a control system used for sending action signals to all the systems; an input end of the main pump assembly is connected with the hydraulic oil tank, and an output end of the main pump assembly supplies oil for the amplitude variation system, the main lifting system, the auxiliary lifting system, the rotary system, the guy system, and the control system through the switch assembly; and the switch assembly is a hydraulic control proportion multi-way valve. According to the control system and the control method, the influence of the impact generated when the load swings and shakes on the crane control system is reduced, the pressure on the crane control system is balanced, and the safety and the stability of the crane control system are improved.

Description

technical field [0001] The invention relates to a crane, in particular to a crane control system and a control method. Background technique [0002] Marine cranes are a special type of cranes that perform transportation operations in the offshore environment. They are mainly used for important tasks such as transportation and transfer of cargo between ships, replenishment at sea, and launching and recycling of underwater operating equipment. Marine cranes are generally controlled by a crane control system. During the working process, the hull pitches, rolls and heaves with the waves. These movements will cause the load to sway and sway. The swaying and swaying of the load will form a huge impact on the control system, causing the crane control system to be unstable. [0003] The crane control system provides power and brakes to the main hoisting winch, auxiliary main hoisting winch, luffing winch and slewing platform. When the oil pressure suddenly increases, the pressure ...
