Embodiment Construction

[0030] A cold dismantling and repairing method for a track circuit insulation device, comprising the following steps:

[0031] 1) Before the insulating splint 2 is installed, the connecting hole is processed into the inner thread 3, and it is bonded to the joint of the rail, and the bolt group is used to connect and fasten the connecting hole of the rail;

[0032] 2) When the insulating splint fails and needs to be disassembled, remove all bolt groups, but the insulating splint 2 is still glued to both sides of the rail 1;

[0033] 3) as figure 1 and figure 2 As shown, one end of the dismantling bolt 5 is threadedly connected with the inner thread 3 of the insulating splint 2 on one side, and the other end extends out of the insulating splint 2 on the other side;

[0034] 4) Hammer the protruding end of the dismantling bolt 5 with a sledgehammer, and the insulating splint 2 threadedly connected with the dismantling bolt 5 is stressed and disengaged from the rail 1 under the...

Abstract

The invention relates to a cold dismantling and repairing method for a track circuit insulation device, which comprises the following steps of: 1) before an insulation clamping plate is installed, processing an internal thread on a connecting hole; (2) when the insulation clamping plate fails and needs to be disassembled, all the bolt sets are disassembled; (3) one end of a dismounting bolt is in threaded connection with the internal thread of the insulation clamping plate on one side, and the other end extends out of the insulation clamping plate on the other side; (4) hammering the extension end of the dismounting bolt by using a sledge hammer; (5) according to the actual separation condition of the insulation clamping plate and the steel rail, selecting the internal thread at the proper position to be in threaded connection with the dismounting bolt again for hammering; (6) a grinding wheel is adopted for grinding residual glue at the bonding position of the insulation clamping plate and the steel rail till the surface is smooth; 7, a new insulation clamping plate is bonded to the original position of the steel rail again, it is guaranteed that the positions of the connecting holes correspond to each other, and the insulation clamping plate and the steel rail are bonded and compressed through the bolt sets.

Description

technical field [0001] The invention relates to a cold dismantling and repairing method for a track circuit insulation device, which belongs to the technical field of emergency repair work for railway works. Background technique [0002] The railway line has generally adopted the seamless line, and the track circuit insulation device generally adopts the glued insulation. The glued insulation will fail due to various reasons, which requires urgent repair. Since it is an existing driving equipment, it is necessary to apply for the repair of the sunroof. There are strict regulations on the time of the sunroof. If the removal or grinding time is too long, the quality of the newly cemented insulation joints in the sunroof point will not be guaranteed, leaving a safety hazard. At present, the on-site dismantling mainly adopts the method of heating the insulating splint with a gas tank to make the adhesive fail and knocking and dismantling it. After dismantling, the grinding of th...
