Description

Technical Field

[0001] The present application relates to the field of glued insulated joints, and in particular, to a disassembly device for bolts at glued insulated joints. Background Art

[0002] The track glued insulated joint is a key track part made by a special process, and is mainly applied to the insulated track circuit of the seamless track and the seamless track turnout. The function of the joint is to connect the rail to the rail and the rail to the turnout at the track joint to form an integrity same as that of a single rail, so as to withstand the impact force, longitudinal force, lateral horizontal force generated when the wheel passes through the rail joint, and the additional temperature force generated by the rail due to temperature change.

[0003] The patent with the existing publication number CN202298378U discloses a railway seamless track insulated joint, including insulated fishplates fixed to both sides of the rail web by bolts and nuts between the rail webs on both sides of the rail. The insulated fishplate is composed of a splint, an insulating layer board and a protection board. The insulating layer board is composed of four layers of PK epoxy films and three layers of alkali-free fiberglass cloth stacked at intervals. An installation glue is filled between the protection board and the rail web. An insulating sleeve is sleeved on the bolt section between the rails, and there is a gasket between the nut and the splint of the insulated fishplate.

[0004] During installation, the glued surface of the rail is polished with a grinding machine, bolt holes are drilled in the rail, and the insulating sleeve is placed in the bolt holes; then, insulating plate pieces are clamped into the gap between the two butt-jointed rails, and the installation glue is applied to the corresponding glued surfaces of the insulated fishplate and the rail, and the insulated fishplate is attached to the glued surface of the rail; finally, the bolt is passed through the two insulated fishplates and the bolt holes and locked by the nut. During this process, as the bolt and the nut are tightened, part of the installation glue will enter the threaded hole, so that the insulating sleeve and the bolt are bonded to the rail.

[0005] After the rail glued insulated joint is damaged, it is necessary to remove and replace the rail glued insulated joint. However, the bolt is firmly bonded to the rail. At this time, the staff usually removes the bolt by means of hammer hitting or crowbar prying. The removal difficulty is relatively high, the efficiency is relatively low, and the working intensity is relatively high, so there is room for improvement. Utility Model Content
