AI Technical Summary
In the construction of double-block ballastless track, turnout fine-tuning requires manual adjustment, which is inefficient, labor-intensive, and difficult. How can we quickly complete the elevation and centerline adjustment of the turnouts and reduce manpower input?
Design a turnout elevation and centerline fine-tuning device, including a moving vehicle, multiple elevation adjusters and centerline adjusters. The device utilizes a servo mechanism and a lead screw module to realize the lifting and lateral adjustment of the turnout sleeper. The lead screw and screw are driven by a fine-tuning servo motor and a joint servo geared motor to achieve rapid adjustment.
It enables rapid lifting and lateral adjustment of turnout sleepers, reduces manual intervention, saves manpower and resources, and improves construction efficiency.
