Along with the daily operation and use of high-speed railway lines, under the influence of internal and external factors such as the change of the internal temperature stress of the steel rail, the acting force of train wheel sets on the steel rail, the settlement of roadbed bridges and the like, various geometric form and position indexes of the steel rail are slowly degraded all the time, so that the continuous detection, maintenance and repair of railway line maintenance departments are required. The main method of adjusting the geometry of the rail is to replace the fastener by removing or replacing part of the fittings in the fastener, which is also called fine adjustment of the rail.
At present, the existing track fine adjustment operation mode is mainly manual operation or simple manual operation hand-held tool, and the operation flow is approximately as follows: a set of operating personnel writes the adjustment data in the track fine tuning operation scheme on the sleeper that corresponds with the stone pencil, another set of operating personnel uses electric spanner or internal combustion spanner to unscrew the fastener screw on the sleeper that is marked with the data afterwards and manual part accessory in the fastener demolish and arrange aside in, the operating personnel will need the accessory of changing to place in proper order by corresponding fastener and use tools such as little crowbar, little hammer to change the accessory, last set of operating personnel is manual to screw back the fastener screw and use electric spanner or internal combustion spanner to tighten the screw, accomplish the fine tuning operation to this section of track promptly.
The existing track fine adjustment operation mode mainly has the following defects:
