[0022] The single strand adjustment module 1 is mainly composed of a horizontal sliding table 3, a lifting box 4 and a bolt wrench 5.
[0023] The horizontal sliding table 3 is a horizontally arranged shell structure with a hollow cavity, and is externally provided with a horizontal motor 301 and internally provided with two horizontal guide columns 302 and a horizontal screw rod 306. A horizontal nut seat 303 is arranged in the horizontal sliding table 3 and is in sliding fit with the horizontal guide columns 302 and in threaded fit with the horizontal screw rod 306. The horizontal guide columns 302 are fixedly arranged in the horizontal sliding table 3. The transmission shaft of the horizontal motor 301 is in transmission connection with the horizontal screw rod 306 through the shell. The transmission shaft of the horizontal motor 301 rotates to drive the horizontal screw rod 306 to rotate. The horizontal nut seat 303 in threaded fit with the horizontal screw rod 306 moves horizontally forward and backward under the advancing and retreating thread action of the thread, and is limited by the horizontal guide columns 302 so that the horizontal nut seat 303 does not produce follow-up rotation and displacement in other directions. The two side surfaces of the horizontal sliding table 3 are further provided with cover plates 305 for shielding the hollow cavity. The shell of the horizontal sliding table 3 is fixedly connected with the frame cage 204.

[0029] Embodiment two: the embodiment provides a use method of the adjusting device as described in embodiment one
[0030] Before the adjustment work starts, the construction personnel turns on the power supply of the whole machine through the display screen 202 on the side of the frame 2, the track detector moves in front of the adjusting device, converts the track state deviation into the amount of adjustment required by the fastener bolt, records the point position of the fastener bolt, and wirelessly transmits to the control system of the adjusting device, after receiving the feedback, the whole machine of the adjusting device starts to move forward, moves to the vicinity of the point to be adjusted, and the visual sensor 406 starts to detect the spatial position of the rail fastener bolt, so that the bolt wrench 5 can be aligned with the shaft center of the bolt. Due to inertia, the adjusting device may not be able to accurately reach the bolt directly above, at this time, under the driving of the horizontal motor 301, the lifting box 4 is slowly slid left and right under the driving of the horizontal sliding table 3, and stops until the bolt wrench 5 is aligned with the shaft center of the fastener bolt. Under the driving of the vertical motor 401, the bolt wrench 5 moves downward along the lifting guide column 402, and stops when the wrench sleeve 506 of the tightening assembly 503 is clamped into the fastener bolt. At this time, the servo motor 501 starts to work, and the sleeve of the tightening assembly 503 rotates, the torque sensor 505 detects the torque of the sleeve in real time during this process, prevents over-adjustment due to excessive adjustment or incomplete adjustment, and stops when the required adjustment amount in the memory is completed, and the tightening assembly 503 rises until it passes the rail surface, and the adjustment work of the rail fastener bolt is completed.
