Gantry type level crossing mobile tram line

Abstract

The invention relates to a gantry-type level crossing mobile trolley line, which has a simple and stable structure, can be easily applied and constructed on newly-built level crossings, as well as existing level crossings in use, and has perfect operation and maintenance and easy maintenance, it includes: a pair of auxiliary rails, which are laid on the left and right outer sides of the railway track at the level crossing, parallel to the railway track, and have a certain length; Therefore, it can move back and forth on the auxiliary rail; the moving tram line, which is connected to the upper part of the frame structure through the insulator, is arranged in parallel with the tram line, and has a certain length; the control part, which controls the driving of the drive motor, so that the frame The structure is operated, and as the frame structure moves back and forth, the second power connection part at both ends of the moving trolley line is connected or separated from the first power connection part of the trolley line, so as to realize power supply or power off.

Description

technical field [0001] The present invention relates to an elevated tram line for providing electric power to running trams, in particular to a gantry-type level crossing mobile tram line, which is set at the level crossing section for running trams For power supply, it is possible to connect and separate the tram line by virtue of the gantry-type mobile tram line equipment, and it can move back and forth along the left and right sides of the level crossing (rail direction), so that the tram line that exceeds the height of the tram line Large / specially equipped vehicles, etc. can pass through level crossings or allow trams to pass through level crossings. Background technique [0002] With the opening of high-speed railways, electrified railways are attracting attention as a new means of transportation in the 21st century. Due to their high speed, large capacity, and short operating time intervals, they are widely used. Therefore, it is required to improve the performance, r...

Problems solved by technology

[0014] However, the structure described in Patent Document 1 is a structure that is driven in a state in which the support structure of the movable trolley line is erected in the air (an overhead erection structure), so it is true that it is suitable for existing operations. It is extremely difficult to cross the level crossing, not only the construction period is too long, the construction cost is high, but also the durability is poor, the maintenance and repair are difficult, and there is a risk of safety accidents
