Abstract
Provided is a steel aluminum contact rail expansion joint. The right end face of a left sliding rail, two end faces of a middle rail and the left end face of a right sliding rail are all inclined faces which are parallel, horizontal long holes are formed in the rail waists of the left sliding rail and the right sliding rail, and a fixed hole is formed in the rail waist of the middle rail. Anchoring clamping plates are installed on two sides of the left sliding rail, the middle rail and the right sliding rail through a connection bolt I, a connection bolt II, the horizontal long holes and the fixed hole, and the anchoring clamping plates are fixedly connected with the middle rail and connected with the left sliding rail and the right sliding rail in a sliding mode. A current connector is a lamination copper foil and is installed at the rail tops of the left sliding rail, the right sliding rail and the right sliding rail in a fastening mode through fixed bolts. A shaft sleeve sleeves the middle of the connection bolt I, and the shaft sleeve is located in the horizontal long holes. Two U-shaped aluminum gaskets symmetrically sleeve the connection bolt II, and the two U-shaped aluminum gaskets are located between the anchoring clamping plates and the rail waists on two sides of the middle rail. The expansion joint can reduce the initial slip force, meanwhile reduces the requirement for the boundary and meets various vehicle matching requirements.
Description
Technical field

Background technology
In urban track traffic steel-aluminum conductor rail electric power system, expansion pipe produces the compensating device of length variations because expanding with heat and contract with cold as steel-aluminum conductor rail, be the important component part of urban track traffic steel-aluminum conductor rail electric power system.At present, the expansion pipe of urban track traffic steel-aluminum conductor rail is various informative, and gauge requires to be not quite similar.But along with the increase of period of service, generally expose the defects such as initial slippage power is large, easily clamping stagnation, electric continued access performance be not good.
Summary of the invention
The technical matters that the utility model solves: design a kind of steel-aluminium contact rail expansion pipe, reduce initial slippage power, meet electric continued access requirement, not only can effective compensation steel-aluminum conductor rail length variations because expanding with heat and contract with cold and producing, reduce the requirement to gauge simultaneously, thereby meet the cooperation requirement of various vehicles.
Technical solution of the present utility model: a kind of steel-aluminium contact rail expansion pipe, consists of left slide rail, mid-rail, right slide rail, anchoring clamping plate, current connector; The left side of the right side of described left slide rail, the both ends of the surface of mid-rail and right slide rail is the inclined-plane being parallel to each other, and is all shaped with horizontal slotted hole on the web of the rail of left slide rail, right slide rail, on the web of the rail of mid-rail, is shaped with fixed orifice; Described anchoring clamping plate are arranged on the both sides of left slide rail, mid-rail, right slide rail by tie bolt I, tie bolt II and horizontal slotted hole and fixed orifice, and make anchoring clamping plate with mid-rail for being fixedly connected with, with left slide rail, right slide rail be sliding block joint; It is characterized in that: described current connector is lamination Copper Foil, on the fastening tread that is arranged on left slide rail, mid-rail, right slide rail of bolt of rear end plate; The middle part of described tie bolt I is set with axle sleeve, and axle sleeve is arranged in horizontal slotted hole; In described tie bolt II, symmetry is set with two " U " shape aluminium backing, and two " U " shape aluminium backing lays respectively between anchoring clamping plate and the mid-rail both sides web of the rail.
Between the tread of described current connector and left slide rail, mid-rail, right slide rail, be provided with copper to aluminum adapter bar and fix by bolt of rear end plate.
The advantage that the utility model compared with prior art has and effect:
1, by " U " shape aluminium backing is set on the web of the rail of mid-rail both sides, and by axle sleeve, left slide rail, right slide rail are positioned, thereby make to have realized free-running fit between left slide rail, right slide rail and anchoring clamping plate, when compensating, by axle sleeve, carry out relative sliding, reduce initial slippage power, slide without clamping stagnation.
2, adopt lamination Copper Foil to realize electric current continued access, not only reliable and stable, reduce the requirement to gauge simultaneously, thereby meet the cooperation requirement of various vehicles.
