Falling rail buffer device and longitudinal rail-changing transport unit

Abstract

The invention provides a rail-falling buffer device and a longitudinal rail-changing transport vehicle set, including: a fixing part, a folding part and a connecting piece; the fixing part includes: an end plate and two opposite first side plates, and two opposite first side plates The ends of the side plates are fixed on the inner side of the end plate, wherein the extension direction of the first side plate is perpendicular to the extension direction of the end plate; the two opposite first side plates are respectively provided with corresponding first through holes ; The folding part includes: a slide plate and two opposite second side plates, the two sides of the slide plate are respectively fixed on the inner sides of the two opposite second side plates; A through hole corresponds to a second through hole; the two opposite first side plates are located outside the two opposite second side plates, and the connecting piece is passed through the first through hole and the second through hole to connect the folding part with the fixed Department can be connected to the activities. The rail falling buffer device and the longitudinal rail changing transport vehicle set provided by the present invention can ensure the integrity of the steel rails during the derailing process.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail-falling buffer device and a longitudinal rail-changing transport vehicle set. Background technique [0002] In the prior art, when new steel rails need to be laid on the railway line, the operators can transport the steel rails to the place where new steel rails need to be laid through the longitudinal rail change transport train set. After arriving at the place where the new rail is laid, the operator can unload the rail from the guide groove of the work vehicle to the place where the new rail is laid through the operation vehicle at the end of the longitudinal rail change transport group, so that the operator can lay new rails on the railway line. rails. [0003] However, because there is a certain height difference between the guide groove of the work vehicle and the sleeper and ballast bed of the railway line, when the operator unloads the rail from the gu...
