In recent years, the high-speed train industry has developed rapidly. On the one hand, the state has increasingly emphasized the safety measures for transportation and production. On the other hand, the people's voice for railway safety has become increasingly strong, which requires more and more railway equipment and the mechanical performance of the track. higher. In order to achieve this goal and ensure the normal operation and production of trains, the railway line must be kept in good condition at all times, which requires regular repair and maintenance of the railway line, including bridges, culverts and tunnels according to the prescribed plan.

At present, the maintenance of railway tracks is mainly manual maintenance. Due to the long railway lines, which are all in the wild, the environment is harsh, the labor intensity is high, the labor cost is high, the efficiency is low, and the maintenance effect is poor.

In the railway maintenance project, the elastic bolt is the main operation item of the railway works department. The current track bolt operation is mainly manual operation, which is labor-intensive and low-efficiency. Therefore, it is particularly necessary to design a track bolt operating mechanism.

In order to achieve the above purpose, the technical scheme adopted by the present utility model is:

An orbital bolt operation mechanism, which can be powered by a motor to drive an annular rotating sleeve to rotate to perform bolt tightening or loosening operations. Over-torque damage, on the other hand, the annular rotating sleeve has oil filling ports, which can be filled with lubricating oil while tightening or loosening the bolts.

The spline sleeve 10 drives the spline shaft 9 and the wrench head rotating sleeve 13 to rotate together so that they have the same rotational speed and torque. , the wrench head rotating sleeve 13 is provided with an annular rotating sleeve 12, a fixed handle 2, an oil filling port 1, a positioning pin 11, a rubber sleeve 3, the annular rotating sleeve 12 and the fixed handle 2 are welded and fixed together, and the fixed handle 2 is connected to the working machine , used to support the whole mechanism, the oil filling port 1 is welded to the upper part of the annular rotating sleeve 12, and the lubricating oil can be filled while the bolt is tightened. Circumferential fixation and axial fixation.

The specific implementation is as follows:

When working, the whole mechanism is powered by a large lithium battery, which is converted into mechanical energy after absorbing electrical energy by the motor 8. After the output shaft of the motor 8 reduces the speed and increases the torque through the planetary reducer 7, it drives the bearing 5 to rotate, and the torque sensor 6 is used for real-time. Detect and feedback control the torque of the whole mechanism to prevent the over-torque damage of the track bolts. The bearing seat 4 is used to support the weight of the motor 8, the planetary reducer 7 and the torque sensor 6. The lower part of the bearing is the spline shaft 9, which is used to transmit torque.
