Description
Technical Field
[0001] The utility model relates to the technical field of seamless rail transfer equipment in track laying of a newly built railway, in particular to a transfer device for laying rails on a newly built seamless railway line. Background Art
[0002] The tracks of my country's high-speed railways and rapid railways are all made of 500-meter seamless line long rails. The speed of laying long rails is particularly critical to the control of the track laying construction period. The operation of laying sleepers and rails on the railway bed adopts a mechanical laying method to assemble the rails and sleepers into track rows at the assembly base.
[0003] For example, the authorization announcement number is "CN109811603A". A transfer device for laying rails on a newly built railway seamless line lifts the pre-transported rails through a pulley sling and suspends them between the two crossbeams of the front and rear frame trolleys. The front and rear trolleys can lift 8 rails at the same time, and the 8 rails are transported to the track laying position by manually pushing the front and rear trolleys. After unloading, wait for the rails to be laid, which improves work efficiency and shortens construction period. Only 4 people are needed to push the two rail lifting and pushing trolleys, which greatly saves labor and transportation costs. However, the device drives the rails to move for laying by lifting annular steel strands and lifting rail clamps. Due to the action of gravity, the rails will shake, affecting the operator's laying, resulting in deviations in the laying of the rails, reducing the accuracy of the rail laying of the device. After the rail laying is completed, gaps will appear in the device, and the operator is required to push the rails for seamless laying, which increases the workload of the operator and reduces the work efficiency of the device.
