Technical Field

The utility model relates to a track bolt operation mechanism, and belongs to the field of track maintenance bolt operation tools.

Background

In recent years, the high-speed train industry is rapidly developed, on one hand, the national security measures for transportation and production are increasingly emphasized, and on the other hand, people have an increasingly strong call for the safety of railways, so that the requirements on the mechanical properties of railway equipment and rails are higher and higher. To achieve this goal and to ensure the proper production of the train operation, the good condition of the railway line must be maintained all the time, which requires regular maintenance and repair of the railway line, including bridges and tunnels, according to a prescribed schedule.

The current railway rails maintenance is mainly for manual maintenance, because the railway circuit is long, and all in the field, the environment is abominable, intensity of labour is big, the cost of labor is high, and is efficient, and the characteristics that the maintenance effect is poor are outstanding.

In railway maintenance projects, the turnbuckle bolt is a main operation project of a railway engineering department, and the main tasks are to loosen and tighten the fastener bolt, the joint bolt and oil coating for the bolt, which account for the main part of main workload. The current operation of track bolt is mainly manual work, and intensity of labour is big, and the operating efficiency is low. Therefore, it is necessary to design a rail bolt operation mechanism.
