Device and method for positioning container in port

Abstract

The invention discloses a device for positioning a container in the port. The device is characterized in that two laser length meters comprising a first laser length meter and a second laser length meter are fixedly connected to a horizontal surface of a carrier; the two laser length meters are arranged in parallel in the same direction; a gap is formed between optical axes of the two laser length meters; the two laser length meters synchronously and continuously emit laser pulse trains, and when the laser pulse trains reach a container truck, distances between the laser length meters and laser irradiation points on the container truck are obtained; an angle relation of a connection line and a location line between the laser irradiation points on the container truck is calculated by a data processing unit; the minimum length of the vertical line from the laser irradiation points of the first laser length meter and the second laser length meter to the location line is calculated; and a display screen displays the minimum distance between the container truck and the location line, and also displays driving instructions of forward / back driving, left / right turning or stopping of the container truck. The device realizes container truck positioning by a starting process. The invention also discloses a method for positioning a container in the port.

Description

technical field [0001] The invention belongs to the technical field of laser measurement, and relates to a method and a device for positioning port containers by using laser technology. Background technique [0002] At present, the loading and unloading of container terminals uses a large number of port shore container cranes, referred to as container cranes. When loading the ship, the container truck takes the container from the freight yard, transports it under the container crane, and stops. The driver of the container crane looks down at the container below, manipulates the spreader to move up and down and left and right, aligns with the container on the container truck, lifts it vertically and moves it to the right to the designated position on the ship. Usually, in order to provide loading and unloading efficiency, the movement of the container crane must be relative to the position of the container on the ship. Like this each lifting, just can only slide in one-dime...

AI Technical Summary

Problems solved by technology

[0012] In order to solve the deficiencies of existing spreader and container alignment technology that affect loading and unloading efficiency, the purpose of the present invention is to provide a port container positioning method and device that can avoid the front and rear adjustment of the spreader and the secondary start-up adjustment of the container truck
