Abstract
The utility model relates to a conductor rail in the city rail transportation equipment, in particular to a conductor rail joint. The conductor rail joint consist of two conductor rails separated in a specific gap, the conductor rail cross section is H-shaped, and between the two conductor rails a conduct block is connected; the conduct block is pressed on the stiffened plate of the conductor rail waist through a crossunder bolt, and the crossunder bolt is passing through the vertical waist type hole on the stiffened plate; the two ends of the conduct block are separately connected with the stiffened plate of the two conductor rails through a conducting flexible joint. The utility model not only compensates the hot-swelling and cold-shrinking, but also is provided with reliable connection and good conducting performance.
Description
Technical field
The utility model relates to the conductor rail in the urban track traffic equipment, is specifically related to a kind of conductor rail joint.
Background technology
In the existing track traffic equipment, its conductor rail blank area connects by the rigidity conducting block, adjusts expanding with heat and contract with cold of conductor rail by the slip between conducting block and the conductor rail, contacts by planar friction between conductor rail and the conducting block and realizes conducting function.In this structure, owing to have the gap between the conduction contact level, oxidizing reaction easily takes place and produces oxide coating in conductor rail and conducting block surface, causes the electric conductivity instability; When conductor rail expansion or shrinkage, along with the Frictional Slipping of conductor rail and joint, resistance value can change at any time because of the plane out-of-flat of contact surface, and heating easily produces spark, thereby has potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of and can compensate expanding with heat and contract with cold of conductor rail, the conductor rail joint that connect again reliably simultaneously, conducts electricity very well.
Conductor rail joint of the present utility model includes the conductor rail of two sections certain intervals of being separated by, and the conductor rail cross section is " I-shape ", is connected with conducting block between two sections conductor rails; Conducting block is pressed in by the cross-under bolt on the gusset of conductor rail waist, passes vertical waist shaped hole of cross-under bolt from gusset, make conductor rail and conducting block can overcome between them friction force and in the length range that waist shaped hole limits vertical slide relative; The two ends of conducting block are connected with the gusset of two sections conductor rails by being flexible coupling of conduction respectively.
The end face of described conductor rail can be arranged to the gusset off plumb inclined-plane with conductor rail, and the end face of two sections conductor rails is parallel to each other.
Described conducting block can have two, and two conducting blocks are clipped in the gusset both sides of conductor rail waist.
The described outside that is flexible coupling can also be provided with baffle plate, and baffle edge is fixed on the conductor rail, and is outwards outstanding to prevent to be flexible coupling.
In the said structure, can also be provided with one section cross section and also be the interlude of " I-shape " between two sections conductor rails, interlude is captiveed joint with conducting block by bolt.
The utility model owing to adopt is flexible coupling and frictional plane realizes that jointly conducting block contacts with conduction between the conductor rail, has improved the current capacity of conductive connection, has guaranteed the safety of conductive stability and operation.

The specific embodiment
As shown in the figure, conductor rail joint of the present utility model includes two sections conductor rails 1 and the one section interlude 5 with " I-shape " cross section that is connected by conducting block 2.Conducting block has two, and it is clipped in gusset 11 both sides of conductor rail waist.The cross-under bolt 3 that connects conductor rail and conducting block passes the vertical waist shaped hole 12 on the gusset of mounting hole on the conducting block and conductor rail, and interlude 5 also is connected with conducting block by bolt.The conducting block two ends 4 are connected on the gusset 11 of conductor rail by being flexible coupling respectively.Being flexible coupling is stopped by the baffle plate 6 in its outside, and it is outwards outstanding to prevent to be flexible coupling when conducting block and conductor rail slide relative.The end face 13 of two conductor rails and the both ends of the surface of interlude are the inclined-plane that is parallel to each other.Employed conduction is flexible coupling and can adopts copper litz wire or stacked copper sheet in the said structure.
