Power supply system of sliding contact line of trench of tyre crane of container yard

Abstract

The invention relates to a power supply system of a sliding contact line of a trench of a tyre crane of a container yard, which comprises a trench cell body and a trench cover plate covered and arranged at an opening part of the trench cell body, the sliding contact line is arranged in the trench cell body along the extension direction of the cell body, a track is arranged by being parallel to the sliding contact line, a current-collecting trolley is movably arranged on the track, an electricity getting device of the current-collecting trolley is in sliding elastic contact with the sliding contact line, a gap is arranged between the trench cover plate and the trench cell body or in the trench cover plate for leading the current-collecting trolley to lead out a conductive wire, a flexible or rigid movable cover can be added at the gap according to the needs, the corresponding current-collecting trolley has the automatic cover-turning function when travelling, and a traction conductive wire is respectively connected with the current-collecting trolley and the tyre crane. The adoption of the power supply system can lead the tyre crane to span a container region in a linear non-interruption manner in the container yard; compared with the existing scheme, the power supply has the advantages of simplicity, practicality, low cost, small occupied space, safety, reliability and a wide range of applications, thereby being an effective complementary way or an effective alternative way of the prior art.

Description

technical field [0001] The invention relates to the technical field of container loading and unloading, in particular to the technical field of a tire crane power supply system in a container yard, in particular to a trench trolley line power supply system for a tire crane in a container yard. Background technique [0002] In modern society, there are more and more various container terminals, and the container terminal yard loading and unloading equipment mainly adopts tire cranes. Most of the tire cranes in the prior art are powered by diesel engines, which are flexible in transition, but the efficiency of the huge diesel generator set is very low, the reactive power consumption is large, the noise is large, and the environment is also polluted by smoke and dust. [0003] At the same time, a system that can directly supply power from the grid has appeared in the prior art, thus changing the tire crane from using diesel to directly using electricity (referred to as "oil to ...

AI Technical Summary

Problems solved by technology

[0006] The container tire crane travels faster in the container area. The large flip cover used in the trench power supply method of the traditional rail crane is heavy, bulky, and slow to flip, which cannot meet the requirements. In addition, the tire crane must meet the load-bearing requirements when passing the container area. Requirements, and the clamshell needs to be strong and heavy. It is very important to solve this contradiction in the container tire crane trench trolley line
