Abstract

The invention discloses a positioning method of a lifting appliance accurate positioning system. A controller controls an ultrasonic emitting module on a container needing to be lifted to emit ultrasonic waves, an ultrasonic receiving module of a lifting appliance body receives the ultrasonic waves, and thus the position of the container needing to be lifted is rapidly found out; when the liftingappliance body moves to the position above the container needing to be lifted, through the joint effects of a laser distance measuring module, the ultrasonic emitting module and the ultrasonic receiving module, the position distance between the lifting appliance body and the container needing to be lifted is accurately measured, and positioning is gradually conducted through a positioning auxiliary plate; and finally, through the effect of an electromagnet B, it is ensured that a rotary lock is coaxial with a lock hole and then enters the lock hole. From the process, it can be known that the continuity and rapidness of automatic coarse positioning, fine positioning and accurate positioning of a lifting appliance are achieved, and the lifting accuracy and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of logistics transportation, in particular to a positioning method for a precise positioning system of a spreader. Background technique [0002] The greatest success of the container lies in the standardization of its products and the entire transportation system established thereby. It is indeed worthy of the standardization of a behemoth with a load of tens of tons, and based on this, the gradual realization of a global logistics system for ships, ports, routes, highways, transfer stations, bridges, tunnels, and multimodal transport. It is called one of the great miracles created by human beings in history. [0003] With the increasing role of containers in logistics. There are cranes for containers at the wharf for lifting and transporting containers. The hook of the crane is hung with a container special spreader that can quickly lift the container, that is, the fixed spreader (also called the integra...
