Crane, control system and method for vertical and horizontal motions of lifting hook thereof, and vehicle

Abstract

The invention relates to a control system and a control method for vertical and horizontal motions of a lifting hook of a crane, the crane, and a vehicle. The control system comprises: an operation panel (100) provided with a first key for controlling the vertical motion of the lifting hook and a second key for controlling the horizontal motion of the lifting hook; a detection apparatus (200) fordetecting motion parameters of a boom of the crane; and a controller (300) connected to the operation panel, the detection apparatus and the boom, respectively, and used for obtaining a geometrical relationship between an extension amount of the boom between a target position and an initial position and an amplitude change angle and a geometrical relationship between the extension amount and a revolving angle by receiving information of the detection apparatus, maintaining the geometrical relationship between the extension amount of the boom between the target position and the initial positionand the amplitude change angle in real time according to a signal of the operation panel to control the vertical motion of the lifting hook, or maintaining the geometrical relationship between the extension amount of the boom between the target position and the initial position and the revolving angle in real time to control the horizontal motion of the lifting hook.

Description

technical field [0001] The present disclosure relates to the technical field of truck cranes, and in particular, to a control system for vertical and horizontal movement of a crane hook, a control method, a crane and a vehicle. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. A truck crane is a hoisting machine that can be used on the road. The driver's cab and the operating room on the car are used for driving and working on the vehicle. Usually, the truck crane performs the crane boarding operation through the joystick in the boarding operation room and the buttons on the operation panel. Among them, the common actions of getting on the car include boom luffing, boom telescoping, hoisting and retracting, and turntable rotation. Most of the existing crane operations are above the hoisted objects through the jib luffing and telescopic, and the heavy object...

AI Technical Summary

Problems solved by technology

However, the vertical operation is just a simple retracting and unwinding of the winch. During the hoisting process, there may be over-rolling or over-releasing working conditions, so the vertical operation of the hoisting load cannot be realized; and the horizontal operation can only be achieved through compound operations. The operating point in the horizontal direction cannot realize the horizontal movement of the heavy object, and human operation may cause certain errors
