Abstract

An overhead rigid catenary temperature compensation device, the outer ends of the left sliding guide rail and the right sliding guide rail are respectively connected and fixed with the bus bars at both ends; The slide rail is inserted in the slideway on the opposite side, and the two sliding guide rails are connected together so that they can slide relatively freely; the lower end of the outer side of the two sliding guide rails is formed with a contact wire slot through the length, and the contact wire slot and the bus bar connected thereto The contact line slot at the lower end corresponds to the slot; the top surfaces of the two sliding guide rails are fixed with guide rods through guide supports and parallel guide seats, and the middle section of guide rods penetrates into the parallel guide seats on the opposite side to follow The two sliding guide rails slide freely. The invention is installed in the overhead rigid catenary system, which compensates the thermal expansion and contraction of the system due to temperature changes, realizes good electrical continuity and smooth transition between the anchor sections, ensures the stable operation of the locomotive, and improves the safety and reliability of locomotive operation .

Description

technical field

[0001] The invention belongs to the technical field of rail transit rigid catenary, and in particular relates to an overhead rigid catenary temperature compensation device. Background technique

[0002] The overhead rigid suspension busbar power supply system will freely expand and contract due to thermal expansion and contraction in the line. At present, the disconnected anchor section joint structure is mainly used for temperature compensation (patent number: ZL 200420043748.1). The two busbars at the joint are arranged in parallel, separated by 200 ~ 300mm, high installation accuracy requirements, complex layout, this structure is mainly suitable for operating speed requirements not greater than 120km / h. There are also expansion elements used for temperature compensation, but due to the structural problems and heavy weight of the expansion elements currently used, arcing and discharge phenomena are prone to occur during line use, and the maintenance worklo...

Embodiment Construction

[0023] combined with Figure 1-7 Specific embodiments of the present invention will be described in detail.

[0024] An overhead rigid catenary temperature compensation device, comprising a left sliding guide rail 2 and a right sliding guide rail 3, the outer ends of the left sliding guide rail 2 and the right sliding guide rail 3 are respectively connected and fixed to the bus bars 1 at both ends through the bus bar outsourcing joint 4, And the top cross section of the outer end of the left sliding guide rail 2 and the right sliding guide rail 3 is the same as the top cross section of the bus bar 1, so as to ensure the reliability of the connection with the bus bar. The inner sides of the left sliding guide rail 2 and the right sliding guide rail 3 are all formed with slideways 13 and slide rails 14, and the two slideways 13 and the two slide rails 14 are staggered up and down, and the slide rails 14 are inserted in the opposite sides. In the side slideway 13, the left slidi...
