AI Technical Summary

Problems solved by technology

Due to the manual implementation, it is difficult to maintain a stable replacement speed. The start and release stages are easy to cause the frog to shake. It takes a lot of manpower to operate the handle. The operator needs to stand near the frog, and the frog is easy to hurt people and cause accidents.
The replacement machine adopts free support, and the support is not stable enough
The delivery of new and old frogs needs to be carried out successively, the steps are cumbersome and time-consuming

Abstract

The invention provides a hydraulic frog change machine. The hydraulic frog change machine comprises a lifting oil cylinder, a swinging oil cylinder and an electric pump station; the electric pump station drives the lifting oil cylinder to lift new and old frogs and drives the swinging oil cylinder to rotate, so that the new and old frogs rotate and exchange with each other in position. The hydraulic frog change machine can change the new and old frogs through one-time lifting, rotation and falling, and the operation is simple and efficient.

Description

technical field [0001] The invention belongs to the technical field of railway transportation, and in particular relates to a replacement machine for replacing a switch frog on a railway line. Background technique [0002] At present, there is no special power mechanical equipment for replacing various frogs in China, and replacing frogs is labor-intensive and time-consuming. The weight of frogs is relatively large, about 0.7-2 tons. The new frogs are transported to the site by railcars or cars, replaced manually in the skylight point, and manually transported to the frogs to be replaced by means of monorail trolleys and crowbars. Near the fork, use a crowbar to shift the frog into place when replacing the frog, including turning the frog over the basic rail and guard rail. The old frog is moved out of the margin of the diverging area in the same way. The manual method of frog replacement usually requires 10-15 people and takes 10-12 minutes. The process of manually shift...
