Pull riveting fastener having anti-falling structure and used for laying railway track

Abstract

The invention discloses a pull riveting fastener having an anti-falling structure and used for laying a railway track, wherein the pull riveting fastener comprises a track panel steel rail; a connecting joint is arranged in a groove on one side of the track panel steel rail, and pull riveting casing pipes are connected in holes formed in the track panel steel rail and the connecting joint; each pull riveting casing pipe comprises a flange base, L-shaped clamping plates, springs, clamping blocks, a casing pipe fixed end, a casing pipe movable end, a clamping ring and a limiting groove; and one side of each flange base abuts against the outer side face of the connecting joint, and the side face, abutting against the connecting joint, of the flange base is fixedly connected with the three L-shaped clamping plates in the radial direction at equal intervals. The pull riveting casing pipes are stably fixed to the two ends of the track panel steel rail and the two ends of the connecting joint, and the problems that a rivet nut vibrates due to infirm connection, a gap is generated between the track panel steel rail and the connecting joint, and finally a pull rivet fastener loosens and even falls off are solved; and meanwhile, the condition that the riveting casing pipes rotate after being vibrated is prevented, and the stability of the pull riveting fastener is improved.

Description

technical field [0001] The invention relates to the technical field of railway laying, in particular to a blind riveting fastener with a fall-off prevention structure for railway track laying. Background technique [0002] When the railway is laid, two rails are connected with a certain number of sleeper rails and fasteners at the starting point of the track laying to form an integral structural part. These structural parts are the rail row, and then the assembled rail row is transported by a flat car. Use a track laying machine to hang and lay on the track bed, and then assemble each section of the rail row. Among them, riveting is a connection method for assembling the rails at both ends of the rail row. As a fastening riveting process, riveting is made into Thousands of manufacturing companies are used to form or fix plates or parts. In riveting, the riveting nuts are first inserted into the pre-drilled holes on the rail, and specific tools such as riveting guns are used ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of blind rivet fastener with anti-falling structure for railway track laying, to solve the phenomenon that the blind rivet nut proposed in the above background technology will vibrate due to weak connection, and the rails of the rail row and the connection There will be gaps between the joints. After repeated vibrations, the gaps between the rails of the rail row and the connecting joints will become larger and larger, and eventually the riveting fasteners will loosen or even fall off.
