Abstract

The invention discloses a hydraulic control handle system. The hydraulic control handle system comprises a pressure oil source (1), a hydraulic control handle and an operating control loop, which are successively connected through an oil way, wherein the operating control loop realizes the operating control through the operation of the hydraulic control handle; the hydraulic control handle system also comprises a proportion pressure reducing valve (10) and a controller for controlling the proportion pressure reducing valve, the proportion pressure reducing valve is arranged on a handle oil inlet oil way (V1) arranged between the pressure oil source and an oil inlet (P) of the hydraulic control handle, and a controller is electrically connected with the proportion pressure reducing valve so as to control the pressure of the hydraulic oil which flows through the proportion pressure reducing valve. Therefore, the opening of the proportion pressure reducing valve is controlled and set through the controller such as computer software, a condition that a human-computer interface control manner can enhance control or replace a manual operation hydraulic control handle manner, the labor operation of the manual operation is avoided, the operation control is accurate, and in addition, the electronic control manner is combined with the proportion pressure reducing valve to realize the movable control and the like.

Description

technical field

[0001] The invention relates to a control system of a hydraulic control handle, in particular to a hydraulic control handle system capable of realizing man-machine interface control or movement control. Background technique

[0002] Truck cranes are generally composed of several types of actuators such as main hoist, auxiliary hoist, luffing, telescopic, and slewing. During the use of the truck crane, the operator manipulates and adjusts the speed of the main hoist, auxiliary hoist, luffing, telescopic, slewing and other actions by operating the hydraulic control handle. Specifically, the truck crane generally has two hydraulic control handles, and the movement of the five actuators of the truck crane in ten directions is controlled by the two hydraulic control handles. The five executive agencies are: main hoist, auxiliary hoist, telescopic, luffing, and slewing. The movements in ten directions are: main hoist up, main hoist down, auxiliary hoist up, auxili...
