Description

Railway track reflux unit Technical Field The utility model relates to the technical field of railway public service instruments, in particular to a railway track reflux device. Background The railway track return line is a 70 square millimeter copper wire (according to the 2.5.13 th rule of the common speed railway service safety rule) used by a public service department for connecting a track circuit when a rail replacement operation is performed, and after the contact part of the bottom of a steel rail and the return line is derusted at the present stage, the two ends of the return line are fixedly installed and connected on the rails at the two sides in a mode of tightening screws by a spanner so as to realize electric connection. However, the installation mode causes long time consumption and slow installation speed of the installation process of the reflux wire, and poor installation stability of the reflux wire, so that poor conductivity of the reflux wire is caused, and the rail circuit is often interrupted, so that personal safety is influenced, and therefore, the railway rail reflux device is developed. Disclosure of utility model The utility model aims to provide a railway track reflux device which solves the technical problems mentioned in the background art. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model discloses a railway track reflux device which comprises a conductive hook, wherein the conductive hook comprises an integrated straight part and a bending part, a wire sleeve is fixedly arranged on the outer side of the bending part of the conductive hook, at least one through hole is formed in the wire sleeve, a first nut matched with the axis of the through hole is fixedly arranged on the outer side of the through hole, a first screw in threaded connection with the first nut is arranged on each first nut, each first screw penetrates through the first nut and the through hole, the tail end of each first screw is in butt fit with a stainless steel pressing piece arranged in the wire sleeve, a clamping block is arranged on the straight part of the conductive hook in a sliding mode, and a clamping groove is formed in one side, opposite to the bending part of the conductive hook, of the clamping block. Further, a second nut is fixedly arranged at the tail end of the bending part of the conductive hook, and a second screw in threaded connection with the second nut is arranged on the second nut. Further, a screw cap of the second screw is fixedly provided with a rotating handle which is vertical to the screw cap. Furthermore, a connecting sleeve is sleeved at the part, close to the tail end, of the straight part of the conductive hook, and a spring is sleeved at the part, located between the clamping block and the connecting sleeve, of the conductive hook. Further, the conductive hook is fixedly provided with a limiting boss at a position between the bending part of the conductive hook and the clamping block. Still further, the straight portion of the conductive hook is far away from the outer peripheral wall of one end of the bending portion of the conductive hook and is provided with external threads, and one end of the connecting sleeve, which is far away from the clamping block, is fixedly provided with a third nut in threaded connection with the straight portion of the conductive hook.
