Abstract
The invention discloses an expansion joint of a ball crimped-type power supply rail, relating to the technical field of the third rail in the city rail traffic. A middle rail is arranged between a right sliding rail and a right sliding rail. Clamping plates are arranged on two sides of the middle rail fixedly. Bolt holes are arranged on the left and the right ends of two clamping plates. A left sliding rail long slot is arranged on the right end of the left sliding rail along the length direction of the rail. Bolts are connected between the left sliding rail long slot and the bolt holes on the left ends of two clamping plates. A right sliding rail long slot is arranged on the left end of the right sliding rail along the length direction of the rail. Bolts are connected between the right sliding long slot and the bolt holes on the right ends of two clamping plates. Balls are arranged between the clamping plates and opposite sides of the left and the right sliding rails. The aluminum rail is clamped by the invention. The left and the right sliding rails are capable of sliding freely at the contact sides of the clamping plates along the line direction. The design demand of the stretching amount of the left and the right rails is satisfied. The resistance obstacle for blocking the stretching is not generated. The power supply stability of the city rail traffic is guaranteed.
Description
Technical field
The present invention relates to the 3rd rail in the urban rail transit technology field, particularly urban track traffic---the technical field of power supply rail.
Background technology
Along with the increase of urban population and road traffic amount, urban track traffic has in recent years obtained development rapidly.Power supply rail provides a kind of measure of the electric power in the urban track traffic at present.
It is several that existing expansion pipe product has clamping plate type connection, the connection of pestle rod-type, flexible wire type connection to be connected with the soft band of closed loop on being electrically connected, though its form is varied, defective in various degree arranged all.Particularly on mechanical connection, face contact crimping is arranged, line contact crimping can firm crimping to track.But it is big to produce sliding resistance when slide rail expands with heat and contract with cold, occur slide rail habitually in the past and can stretch out and fail smooth indentation, so that the joint displacement, cause collector shoe to be hung and take off, influence locomotive and be subjected to.
Summary of the invention
The object of the invention is to propose a kind of expansion pipe that is beneficial to the good ball compression joint type power rail of the slipping property that expands with heat and contract with cold.
The present invention includes a left side, right slide rail and be arranged in a left side, mid-rail between the right slide rail, the clamping plate of length greater than mid-rail are set respectively separately in the both sides of mid-rail, described two clamping plates is bolted to connection on mid-rail, left side at described two clamping plates, right two ends are provided with bolt hole respectively, along the length direction of track left slide rail elongated slot is set at the right-hand member of described left slide rail, between the bolt hole of described left slide rail elongated slot and the left end of described two plate holder plates, be connected first bolt, along the length direction of track right slide rail elongated slot is set at the left end of described right slide rail, between the bolt hole of described right slide rail elongated slot and two clamping plates right-hand member, is connected second bolt; Ball is set respectively between the opposite face of described two clamping plates and left and right slide rail.
The present invention adopts clamping plate and a left side, the crimping of right slide rail millet cake face, both can clamp the aluminium rail, guarantee left slide rail, middle rail, the positive mechanical of right slide rail connects, can make a left side again, right slide rail freely moves cunning at the contact surface upper edge of clamping plate line direction, clamping plate middle part and middle rail level engage firmly, make mid-rail and clamping plate not produce displacement on any direction, particularly on a two clamping plates and a left side, be provided with ball respectively between the contact surface of right slide rail, this crimping slide construction has satisfied the designing requirement of left and right sides rail stroke, can not produce and hinder flexible resistance obstacle, can ensure the power supply stability of urban track traffic, improve the safety in operation of urban track traffic.
Make for convenience, install, the present invention is provided with the ball groove on the clamping plate surface towards left and right slide rail, in described each ball groove ball is set respectively.

Fig. 2 bows to view for Fig. 1's.
Fig. 3 is the A-A cross sectional drawing of Fig. 1.
Fig. 4 is the B-B cross sectional drawing of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, the present invention is provided with left slide rail 1, right slide rail 2 and is arranged in mid-rail 3 between the left and right slide rail 1,2.The upper and lower two clamping plates 4,5 of length greater than mid-rail 3 is set respectively in the both sides of mid-rail 3, and two clamping plates 4,5 is fixedly connected on the mid-rail 3 by bolt 6,7.
Left and right two ends at two clamping plates 4,5 are provided with bolt hole respectively, along the length direction of track left slide rail elongated slot 1-1 is set at the right-hand member of left slide rail 1, between the bolt hole of left slide rail elongated slot 1-1 and the left end of two plate holder plates 4,5, be connected first bolt 8, along the length direction of track right slide rail elongated slot 2-1 is set at the left end of right slide rail 2, between the bolt hole of right slide rail elongated slot 2-1 and two clamping plates 4,5 right-hand members, is connected second bolt 9.
As shown in Figure 3, between the opposite face of clamping plate 4 and left slide rail 1, ball 10 is set, between the opposite face of clamping plate 5 and left slide rail 1, ball is set also.
As shown in Figure 4, between the opposite face of clamping plate 4 and right slide rail 2, ball 10 is set, between the opposite face of clamping plate 5 and right slide rail 2, ball is set also.
Concrete set-up mode is: on clamping plate 4,5 surfaces towards a left side ball groove is set respectively, in each ball groove ball 10 is set respectively.
Claims (2)
