Automatic aligning device of container truck and quay crane

Abstract

The invention relates to an automatic aligning device of a container truck and a quay crane. The plane position and contour of a container are projected on the ground through LED projection lamps of lamplight devices, so that visual view information is effectively provided for a driver, and the phenomena that the driver frequently backs the container truck up and the container needs to be collided and put down through backing up are avoided. A laser distance meter, a laser scanner, a PLC and an in-place indicating lamp are combined, and therefore the phenomenon that the driver of the container truck start before a lifting appliance of the quay crane does not leave the container and lift to the safe height can be prevented, the situation that the driver of the container truck pulls a brake to stop the container truck is avoided, the alignment time of the quay crane and the container truck is effectively shortened, the operation efficiency of wharf ships is obviously improved, the comprehensive cost of operation of the container truck is effectively reduced, and the driving fatigue degree of the driver of the container truck is obviously improved.

Description

technical field [0001] The invention relates to the alignment of container trucks and spreaders in container loading and unloading operations, in particular to an automatic alignment device for trucks and quay bridges. Background technique [0002] Quay cranes, also known as quayside container cranes and bridge cranes, are equipment used to load and unload containers on ships on the shore. In the Yangtze River inland wharf, as the throughput of container operations increases, the frequency of quayside crane operations increases accordingly. During the loading and unloading process, the container truck must frequently move the operating bay. How to quickly and reliably achieve a positioning has become a current problem. The working habit of truck drivers in wharf operations is to call on the walkie-talkie and look up to determine the size of the box currently working. The positioning basically relies on personal experience to choose a reference point on the quay crane truck f...

AI Technical Summary

Problems solved by technology

The working habit of truck drivers in wharf operations is to call on the walkie-talkie and look up to determine the size of the box currently working. The positioning basically relies on personal experience to choose a reference point on the quay crane truck for alignment, and some even wait until the crane. The box hangs on the upper part of the truck platform and waits for the truck driver to reverse the car and touch the box to release the box. After the box is placed, some trucks start when the quay crane spreader is unlocked and rise to a safe height in blind pursuit of operating speed. It often leads to the "pull off" phenomenon of collecting cards

The frequent reversing of the trucks also caused a large amount of repairs to the clutches, gearboxes and other mechanisms of the trucks, which also brought certain safety hazards to the company's safe production and safe operation of equipment
