Problems solved by technology

After a long time of operation, the insulating end plate will be damaged. Once the insulating end plate is damaged, the current treatment method is to replace it as a whole. After removing the damaged set of glued insulating joint devices, reinstall a new set It takes about 40 minutes for the glued insulating joint device. The cost of a set of glued insulating joint device plus labor costs is about 10,000 yuan. It can be seen that replacing a complete set of glued insulating joint device is time-consuming, laborious and expensive.

Abstract

The invention relates to a method for repairing an insulating end plate at a glued insulating joint, and belongs to the technical field of railway engineering maintenance. According to the method, therepairing device is fixed to a steel rail, the damaged insulating end plate is cut off through the repairing device, the cut fracture is cleaned, glue is injected into the cut fracture through the repairing device, the repairing device is detached after glue injection is completed, and after glue at the glued insulating joint is solidified and formed, repairing work is completed. The method is scientific and reasonable, the process is simple, the repairing device is convenient to operate, the repairing operation time is greatly shortened, the insulation life of the repaired new insulation endplate can be kept for more than one year, the use and maintenance cost of field operation is greatly reduced, manpower, material resources and financial resources are saved, and the method is worthyof application and popularization.

Description

technical field [0001] The invention relates to the technical field of railway maintenance, in particular to a method for repairing insulating end plates at glued insulating joints. Background technique [0002] With the development of high-speed and heavy-duty railways, seamless lines are widely used in countries all over the world. When the seamless line is connected by glued insulated joints, the glued insulated joints are installed at the demarcation points or intervals of the block partitions of the railway signal machine to meet the separation needs of the block partitions of the track circuit. The glued insulating joint device consists of insulating end plates, rail end insulating plates, high-strength bolts, locknuts, high-strength flat washers, insulating sleeves, and reinforced cement. Apply a high-strength adhesive to make it a glued insulated joint. After a long time of operation, the insulating end plate will be damaged. Once the insulating end plate is damage...
