Multi-way valve control system for forklift

Abstract

The invention relates to the technical field of electric patrol cars, in particular to a multi-way valve control system for a forklift. The multi-way valve control system comprises a multi-way valve,an actuating mechanism and a manipulator; the manipulator consists of an arm-operated switch assembly, a hand-operated switch assembly and a toggle switch assembly; the arm-operated switch assembly isarranged on a forklift body; the hand-operated switch assembly is arranged on the arm-operated switch assembly; the toggle switch assembly is arranged on the hand-operated switch assembly; the actuating mechanism is connected to a valve rod of a multi-way valve; and the actuating mechanism can be controlled to move so as to press down or pull up the valve rod of the multi-way valve when the manipulator is operated. An operator can conveniently operate a plurality of switches of the multi-way valve at the same time, the operation comfort and safety are improved, the multi-way valve and the manipulator are independent structures, the relative position does not need to be considered during arrangement, and arrangement of the whole forklift is facilitated.

Description

technical field [0001] The invention relates to the technical field of forklift multi-way valves, in particular to a multi-way valve control system for forklifts. Background technique [0002] Forklift is an industrial handling vehicle, which plays a very important role in the logistics system and is the main force in material handling equipment. It is widely used in ports, stations, airports, freight yards, factory workshops, warehouses, distribution centers and distribution centers etc., and can enter the cabin, carriage and container for loading, unloading and handling of palletized goods. It is an indispensable equipment for pallet transportation and container transportation. [0003] The multi-way valve operating mechanism is the main control part of the forklift. The forklift driver controls the lifting, side shifting and tilting of the forklift by operating the handle on the multi-way valve operating mechanism. At present, in the control device of the forklift multi-...

AI Technical Summary

Problems solved by technology

At present, in the control device of the forklift multi-way valve, one joystick is generally used to correspond to one valve plate in the multi-way valve, so that multiple valve plates correspond to multiple joysticks. The two operating handles are arranged within the control range of the driver's arm, which brings certain difficulties to vehicle manufacturing and also brings more inconvenience to the manipulation of the vehicle.

Since the driver usually sits on the driver's seat to control the multiple joysticks of the multi-way valve, the driver is labor-intensive during the operation.
