A current collector of an automatic power-taking device for a trolley line

Abstract

A current collector of an automatic power-taking device for a trolley line, comprising a collector frame for installing the collector on the power-taking device, and a carbon brush installed on the collector frame, the collector frame includes a base and a The fixed frame at the front end of the base, the two sides of the fixed frame are respectively provided with a rotating shaft along the extending direction of the fixed frame, and a plurality of upwardly arranged shaft seats are respectively hinged along the length direction of the rotating shaft at intervals, and the rotating shafts on both sides The shaft seats on the top correspond one by one to the left and right, and the carbon brush bracket is hinged on the shaft seat. The carbon brush bracket includes a first part and a second part that are bent with each other, and the carbon brush is hinged to the outer end of the second part. The current collector of the present invention adopts a crossed carbon brush structure, which can make the structure of the entire current collector more compact and light. Under the premise of ensuring strength, the weight is much lighter than other designed current collectors, and the vibration of RTG during driving The impact on the carbon brush is much smaller, and it is easier to fit the sliding contact line.

Description

technical field [0001] The invention relates to an automatic power-taking device for a trolley line, in particular to a collector in the automatic power-taking device for a trolley line. Background technique [0002] At present, there are two main types of lifting machinery (commonly known as yard bridges) commonly used for container yard operations in major ports in the world. One is rail-mounted container gantry cranes, namely Rail-mounted gantry cranes, abbreviated as RMG, and the other is tire-mounted gantry cranes. Container gantry crane, namely rubber-tyred container gantry crane, abbreviated as RTG. RMG uses mains power supply, which has low energy consumption but is limited by the track and cannot be switched between various storage yards. RTG has its own diesel generator set for power supply, which is flexible in transition, but consumes high energy and causes pollution. At present, there have been RTG devices with the advantages of low energy consumption and low p...

Problems solved by technology

Such carbon brushes generally occupy a relatively large position, so the volume of the entire collector trolley increases, which in turn increases the processing difficulty of the collector trolley and the connecting device.

[0007] Moreover, the activity of the carbon brush in such a carbon brush structure is low, and the carbon brush cannot adapt to the trolley line and has a certain range of adjustment. In the case of vibration or strong wind, it is easy to loosen the carbon brush and sliding contact wire, resulting in poor power supply
