Talking of fish plate bolts, I'm sure you can think of anything along the lines of a railroad that uses switches to connect two tracks, primarily to move a train from one track over the other. fish plate bolts is a weak link in train. Many problems will be encountered in use. If we want to solve these problems, we need to understand them. Let's follow the manufacturer of fish plate bolts to understand the common diseases of fish plate bolts.

Diseases left over during the assembly and laying of fish plate bolts: The main diseases left over during the assembly and laying of fork bolts include the burying of electrochemical columns after the railway electrification transformation, which leads to the deviation of the two intermediate junctions, resulting in the bad direction of the ferry, and the hard bending of the basic rail, the sharp rail and the wheel guard rail. The location of the concrete fork tie is not correct, one side is offset; The joint is not uniform when the two sections are assembled.

Typical diseases produced by the operation of fish plate bolts include but are not limited to the following: crushing and failure of rubber gaskets; The heel connecting plate of the switch rail is broken; Side rail corrosion; Slide bed platform off welding; Corrosion and wear of parts; Pad hole wear, track surface wave wear; Side grinding of switch rail and basic rail; The corrosion pore size is enlarged; Protect wheel and rail wear; Basic rail wave wear; Anchor bolt nylon sleeve failure; The middle gauge of the switch rail is enlarged; Dark pit hanging plate, etc.

Problems in maintenance: If the maintenance is not handled properly, it will also lead to acceleration switch disease. For example, the staff lack of understanding of the daily maintenance of the acceleration switch and subjectively believe that the acceleration switch does not need to be fully started and solidified; The diseases left over in the process of accelerating turnout assembly and laying are not corrected accordingly. Maintenance machinery tools can not meet the requirements of equipment renewal; The staff did not handle the disease properly, resulting in gradual changes in the disease.
