Claim be arranged on the rectangular frame, every group of drum lifting assembly include both ends connect with vertical link be transversely mounted bar, pass through
Wear be transversely mounted bar and the leading screw parallel with vertical link, using leading screw as the symmetrically arranged limit track of symmetry axis, sliding be arranged
Axle bearing mount portion in limit track and the bearing being arranged in axle bearing mount portion；It is transversely mounted on bar and is provided with and leading screw
The threaded hole of screw-thread fit；The top of leading screw, which is stretched out, to be transversely mounted outside bar, and bottom end is rotatablely connected with axle bearing mount portion；Bearing is vertical
In axle bearing mount portion, outer ring is fixedly connected with axle bearing mount portion；It is provided on axle bearing mount portion and matches with the inner ring of bearing
Longitudinal through hole of conjunction.
Further, threaded hole is located at the midpoint for being transversely mounted bar.
Further, leading screw, which stretches out to be transversely mounted on the body of rod of bar, is fixedly installed swing handle.
Further, diagonal brace is provided between vertical link and limit track.
Further, the both ends of longitudinally reinforced bar are connect by U-bolt with the vertical link.
Further, diagonal brace is welded between the vertical link and limit track.
Further, pedestal is formed by angle steel and steel-pipe welding.
Compared with prior art, the advantage of the utility model is：
Railway drum transport and clue erection construction during among newly built tunnels or on circuit without interim entrance location
When drum can not be transported into construction site using big machinery, railroad track provided by the utility model is put with pay off rack
It sets above circuit rail, drum is hung within the scope of pay off rack and after being aligned at circuit rail center using crane, utilizes people
Work rotates two leading screws and axle bearing mount portions and bearing is driven to move up and down, adjust bearing inner race and wire coil center shaft it is contour after, will
Drum rotation axis is penetrated by a side bearing, is pierced by by another side bearing after drum centre bore, by the both ends of drum rotation axis
It is fixed against it from bearing to deviate from, manual rotation's leading screw makes drum be raised up to preset height.For the sake of security, drum reaches
To after preset height, can be bundled drum to longitudinally reinforced bar with jack makes its fixation.Using manually by track with putting
Coil holder is pushed into clue and sets up point, releases fixed jack, carries out manually setting up clue, after the clue on pay off rack is set up,
Using pay off rack is manually pushed into clue transfer office, then prepare to transport drum next time and clue is set up.It is transported when completing clue
And after clue erection construction, track can be unloaded with pay off rack, deposit storehouse is taken care of, so as to next construction usage.By upper
It is found that railroad track pay off rack provided by the utility model is simple in structure, low manufacture cost is easy to operate, convenient transportation, work
Make it is efficient, have certain promotional value and use value, and by bearing drive drum rotation, reduce because of drum weight
The influence of the artificial excessive generation of unwrapping wire frictional force is caused greatly.
