Modern trams have great qualitative changes in control, vehicle technology, traction power supply, communication signals and the like. The characteristics of large transportation amount, comfort, safety, rapidness, convenience, energy conservation, noise reduction, environmental protection, zero pollution and low manufacturing cost are increasingly highlighted. Orbital downside of trolley is the current-receiving face, and the bow that receives through the trolley-bus top supplies energy to the trolley-bus, and current track hoist structure is unstable, can lead to the trolley-bus to receive the electric unstability, and current hoist can not be to the adjustment height simultaneously, if the error appears in the installation, can't adjust the track depth of parallelism.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a stable in structure, can adjust the track hoist of height to solve above-mentioned problem.
The technical scheme is as follows: the utility model discloses a rail lifting appliance, which is characterized by comprising a fixed seat, a first connecting piece, a second connecting piece, a third connecting piece, an insulator and a fixed claw; the fixed seat is connected with a vertical beam of the electric vehicle platform; the first connecting piece is in an inverted Y shape, the upper end of the first connecting piece is connected with the fixed seat, and the lower end of the first connecting piece is connected with the second connecting piece; the second connecting piece and the third connecting piece are connected through two bolts, the second connecting piece, the third connecting piece and the bolts are in a frame shape, and the second connecting piece, the third connecting piece and the bolts are positioned in the same plane; the lower part of the third connecting piece is connected with an insulator, the insulator is connected with a fixed claw, and the fixed claw is used for connecting a track.
The lower end of the bolt penetrates through the third connecting piece and is provided with nuts from top to bottom.
The lower surface of the second connecting piece is provided with a strip-shaped groove, and the interior of the groove is wider than the opening of the groove; the tail end of the bolt extends into the groove, and the tail end is provided with a nut which is clamped with the edge of the groove so as to enable the bolt to slide in the second connecting piece.
And a waist-shaped hole is formed in the center of the third connecting piece, and a bolt on the upper part of the insulator is connected with the third connecting piece through the waist-shaped hole.

The side of the first connecting member 4 is provided with a ground wire holder 13 for fixing the ground wire to prevent the ground wire from contacting the hanger.
The second connecting piece 5 is rectangular hollow billet or solid billet, and when the second connecting piece 5 was hollow billet, the lower surface was equipped with rectangular shape opening, and the opening width is less than the billet width, and when the second connecting piece 5 was solid billet, the lower surface was equipped with rectangular shape recess 14, and the recess is inside to be wider in the groove opening department. The two ends of the second connecting piece 5 are connected with a third connecting piece 8 through two bolts 6, the upper ends of the bolts 6 are arranged in the openings or the grooves, and the lower ends of the bolts are connected with the third connecting piece 8 in a penetrating way. The upper end of the bolt 6 is T-shaped or provided with a nut, so that the upper end of the bolt 6 can be fixed in the second connecting piece 5, the bolt 6 can slide in the notch or groove of the second connecting piece 5, the horizontal position of the lower structure of the lifting appliance can be adjusted, and the horizontal position of the track can be adjusted. The lower extreme of bolt 6 all is equipped with nut 7 on the upper portion and the lower part of third connecting piece 8, through the vertical height of the adjustable hoist lower part of nut, and then adjusts the orbital vertical height of hoist and mount, guarantees the parallel and level of track water receiving surface 1.
The middle part of the third connecting piece 8 is provided with a kidney-shaped hole 15, and a bolt at the upper end of the insulator 9 passes through the kidney-shaped hole 15 and is fixedly connected with the third connecting piece 8. The horizontal position of the lower structure of the lifting appliance can be adjusted by adjusting the position of the bolt in the waist-shaped hole, and the position of the track can be further adjusted. And a fixed claw 10 is connected below the insulator 9 and used for fixing and hoisting the tramcar track 2.
