Auxiliary cold disassembly equipment for railway cementing insulation joint

Abstract

The invention relates to the field of railway track dismounting auxiliary equipment, in particular to auxiliary cold disassembly equipment for a railway cementing insulation joint. The equipment comprises a mobile cart and a dismounting bracket frame, the dismounting bracket frame is arranged at the side part of the movable cart; dismantling drill bits are arranged on the dismantling bracket frameand comprise rail head drill bits, rail waist drill bits and rail bottom drill bits, the rail head drill bits are arranged at the top of the inner ring of the dismantling bracket frame, the two railwaist drill bits are arranged on the same side of the inner ring of the dismantling bracket frame, the rail bottom drill bits are arranged at the bottom of the inner ring of the dismantling bracket frame, and an electric saw is further arranged on the dismantling bracket frame. The movable cart is pushed to the side of the rail, so that the dismantling bracket frame is located on one side of the rail, the tips of the rail head drill bits, the rail waist drill bits and the rail bottom drill bits and chain teeth of the electric saw are aligned to a gap between the cementing insulation connectorand the rail, forward drilling and multi-angle dismantling are conducted at the same time, and prying and hammering are matched, so that the cementing insulation connector is loosened and disengaged from the rail. The equipment is simple to operate and high in dismounting efficiency.

Description

technical field [0001] The invention relates to the field of railway track dismantling auxiliary equipment, in particular to an auxiliary cold dismantling equipment for railway glued insulating joints. Background technique [0002] The glued insulating joint is one of the track parts made by a special process. It is mainly used in insulating track circuits of seamless lines and insulated joints of seamless line turnouts, which increases joint resistance and ensures that the resistance of joints meets the requirements of seamless lines during the line overhaul period, making the joints smooth and stable. Inspection The maintenance workload is small. The glued insulating joint is mainly composed of track insulating joint splints, insulating joint bolts, insulating sleeves, insulating gaskets, and special reinforced A and B cements. Among them, the track insulation joint splint is also called the fish plate, commonly known as the road splint, which plays a connecting role at ...

AI Technical Summary

Problems solved by technology

In addition, due to continuous use, the insulation of the glued insulated joint will also decrease, and it will not meet the use standard

[0004] Therefore, it is necessary to regularly inspect and maintain the track glued insulating joints, and remove the glued insulating joints that have cracks, deformations or insulation failures. However, in the current demolition technology, there are still many defects and deficiencies, such as heating Removal requires a lot of equipment and requires the cooperation of multiple people, which is inconvenient to operate; or relying on tools such as long-stem wrenches, hammers, and chisels, the removal of multiple bonding surfaces of glued insulating joints is not complete, resulting in low removal efficiency and time-consuming Long, labor-intensive, often cannot complete the dismantling work in the skylight in time
