Railway steel rail gluing insulation joint glue removing machine

Abstract

The invention discloses a railway steel rail gluing insulation joint glue removing machine. The machine comprises a clamping and fixing device, a walking device, a gluing destroy device and a glue removing device; the gluing destroy device finishes the destroy of glued surfaces by a hydraulic cylinder pushing a wedged disassembly head to insert in the glued surfaces; the glue removing device comprises a vertical feeding mechanism, a horizontal feeding mechanism, a scraping cutter mechanism and a scraping wheel mechanism; a vertical aligning mechanism drives the horizontal feeding mechanism and parts thereon for glue removing positioning; the horizontal feeding mechanism drives the scraping cutter mechanism and the scraping wheel mechanism thereon to move along rails to remove glue; and the scraping cutter mechanism and the scraping wheel mechanism are contacted along the glued surfaces to move to finish two-step removing process. The machine effectively solves the problems of time and power saving in manual glue removal of steel rail gluing joints, guarantees thorough removal of the glue, and prevents damage of the rails.

Description

technical field [0001] The invention relates to a railway maintenance device, in particular to a glue removing machine for glued insulating joints of railway rails. Background technique [0002] Rail glued insulating joints are used in station seamless lines at the entrance and exit signals and in turnouts to ensure the normal operation of track control circuits. The glue process or line operation caused the bonding between the joint and the rail to fail to meet the requirements of the line. It is necessary to remove the old joint and replace it with a new joint, and re-glue and fix it to meet the line requirements. It takes about 20 minutes to knock off the joint with a hammer, and then use a tool to remove the residual adhesive, which is laborious, time-consuming and easy to damage the rail. In addition, there is equipment to burn the joint with a welding torch, and heat the joint until the glue becomes soft. Or melt to make the adhesive force smaller and take off the joi...

AI Technical Summary

Problems solved by technology

[0005] The beneficial effect of the present invention is that the wedge-shaped dismantling head is driven by hydraulic power to destroy the glued joint and expand its cracks so that the two parts of the glued joint are separated, which effectively solves the time-consuming and laborious problem of manual stripping in the traditional way. The two steps of scraping and wheel grinding remove the residual adhesive, so that the quality of the glued surface is guaranteed, avoiding damage to the track, which is conducive to the gluing operation again, and can prolong the service life of the track
