AI Technical Summary

Technical Problem

The existing train stoppers are inconvenient when dismantling and replacing, with a high failure rate, and the compression spring is insufficient to overcome the resistance rebound. If the accumulator is too large, it will damage quickly, and the rebound resistance failure rate is high.

Method used

The safety stopper of the train overturner using a dual mechanism includes a horizontal force-receiving unit, a tension transmission unit, a stopper and an auxiliary spring accumulator unit. Through the combination of the pull rod, a pin and a spring accumulator, the normal reciprocating action of the stopper is realized and the disassembly process is simplified.

Benefits of technology

The normal reciprocating action of the stopper is realized, the failure rate is reduced, the replacement process is simplified, the safety is improved, and the risk of car slipping caused by stopper failure is reduced.

Abstract

The utility model discloses a safety stopper of a train dumper, and relates to a track brake fixed on a line. Comprising a horizontal stress unit, a tension transmission unit, a stopper and an auxiliary spring force storage unit, the horizontal stress unit comprises a roller, a roller fixing bracket and a pushing connecting plate; one end of the roller fixing bracket is coupled with the roller; the other end of the roller fixing bracket is symmetrically hinged with two pushing connecting plates; the rollers are used for being matched with a transfer platform located on one side of the track. The tension transmission unit comprises a pull rod, one end of the pull rod is hinged to the end, away from the roller fixing support, of the push connecting plate, and the other end is hinged to a stopper through a hinge connecting plate assembly. A fixed balancing weight is arranged at one end of the stopper, and the auxiliary spring force storage unit is positioned below the bottom of the other end of the stopper; the auxiliary spring force storage unit comprises a compression spring; the normal reciprocating action of the safety stopper is ensured by adopting double mechanisms, and the problems that the existing train stopper is inconvenient to disassemble and replace and high in failure rate are solved.
