Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Such as figure 1 As shown, a hybrid system of "receiving-returning" on the T-rail ground of an electric locomotive includes a base 1, a receiving rail 3, a returning rail 4, and a carbon slide 5; the base 1 is laid between the two tracks, and the receiving rail The rail 3 and the return rail 4 are respectively fixed on the left and right sides of the base 1 through the steel plate 2; the carbon slide plate 5 of the flow-receiving part is fixed on the bottom of the vehicle through a shock absorber, and is in sliding contact with the flow-receiving rail 3; the carbon slide plate 5 of the flow-receiving part It is fixed on the bottom of the vehicle through another damping device, and is in sliding contact with the return rail 4.

[0022] The base 1 of this embodiment is an inverted "T"-shaped reinforced concrete member whose vertical plat...

Abstract

The invention discloses a "receiving-returning" hybrid system on the T-rail ground of an electric locomotive, which includes a base, a receiving rail, a returning rail and a carbon slide; the base is laid between the two rails, and the receiving rail and the returning rail are respectively It is fixed on the left and right sides of the base through steel plates; the carbon slide plate of the flow-receiving part is fixed on the bottom of the vehicle through a shock absorber, and is in sliding contact with the flow-receiving rail; the carbon slide plate of the return flow part is fixed on the bottom of the vehicle through another shock absorber, and Sliding contact with return rail. The invention not only effectively solves the problems of stray current and car body circulation caused by the traditional grounding scheme, but also effectively solves the problem of bonding between the carbon slide plate and the surface of the current receiving rail during the operation of the train, and improves the quality of current receiving; in addition, it can also reduce the Laying costs, saving space, and facilitating later maintenance and management.

Description

technical field [0001] The invention relates to the technical field of rail transit power transmission, in particular to a ground "receiving-returning" hybrid system of T-rails for electric locomotives. Background technique [0002] At present, the electric traction locomotive mainly adopts the "pantograph-catenary system" method to receive current, that is, the pantograph on the roof supports the carbon skateboard bow head and the contact wire erected above the train track to produce frictional contact to realize the transmission of electric energy; or " "Third rail current receiving system", that is, a rigid third rail is installed next to the train track, and the current receiving device located under the side of the train is in sliding frictional contact with the surface of the rigid third rail to realize the transmission of electric energy. The electric traction locomotives powered by the above two current receiving methods feed back part of the electric energy to the t...
