Four-position linkage operating system for truck with crane

Abstract

The invention discloses a four-position linkage operating system for a truck with a crane. The system comprises a four-position linkage operating system assembly, a left operating mechanism and a right operating mechanism. Two fixed adjusting shaft rods are vertically arranged on the two sides of the four-position linkage operating system assembly symmetrically. According to the four-position linkage operating system, four operating connecting rods are arranged in the four-position linkage operating system assembly in an integrated manner, meanwhile, four left adjusting handles and right adjusting handles on the left operating mechanism and the right operating mechanism are arranged to carry out linkage control on the four operating connecting rods, first adjusting handles and second adjusting handles are further arranged at the two ends of the four-position linkage operating system assembly to carry out linkage control and adjustment on the four operating connecting rods, four-position linkage operation control is achieved, other adjusting handles can be used for emergency operation when a certain adjusting handle breaks down, the safety of work is improved, meanwhile, cooperativework is facilitated, and greater convenience is achieved during operation control.

Description

technical field [0001] The invention relates to the technical field of linkage operating systems, in particular to a four-position linkage operating system for truck-mounted cranes. Background technique [0002] The straight-arm crane of the truck-mounted crane is installed between the cab and the carriage. When the vehicle is working, power is taken from the gearbox in the cab to drive the hydraulic pump to rotate and provide high-pressure oil to each component, so that the straight-arm crane can move in various directions on the truck-mounted crane. The bit linkage operating system is a mechanism installed on the truck-mounted crane for linkage operation and control of the truck-mounted crane. At present, the operation and control mechanism of the truck-mounted crane is relatively simple, and only realizes the driving operation control through a single handle, lacking linkage The operation control measures make it impossible to carry out emergency treatment when a fault o...

Problems solved by technology

When the vehicle is working, power is taken from the gearbox in the cab to drive the hydraulic pump to rotate and provide high-pressure oil to each component, so that the straight-arm crane can move in various directions on the truck-mounted crane. The bit linkage operating system is a mechanism installed on the truck-mounted crane for linkage operation and control of the truck-mounted crane. At present, the operation and control mechanism of the truck-mounted crane is relatively simple, and only realizes the driving operation control through a single handle, lacking linkage Operation control measures, emergency treatment cannot be performed when a fault occurs, the safety is low, and it is not convenient enough in actual use, and the overall operating mechanism is large, the installation is not convenient enough, and it is not convenient for the staff to operate
