Detailed Description
The apparatus provided by the present invention will be further specifically described below by way of specific embodiments with reference to the accompanying drawings.
The clamping device for transverse deviation correction of the ballastless track structure provided by the embodiment of the invention comprises a length-adjusting sleeve 1, a length-adjusting screw rod 2, a connecting sleeve 3 and a leveling end plate 4.
And before the transverse deviation correction of the ballastless track structure is implemented, assembling and connecting the four parts of the clamping device. The specific assembly connection mode is as follows: connecting an internal thread sleeve 1-2 of the length-adjusting sleeve 1 with an external thread screw rod 2-1 of the length-adjusting screw rod 2 through screw threads; connecting the external connecting thread 2-3 of the length-adjusting screw rod 2 with the internal connecting thread 3-1 of the connecting sleeve 3 through a screw thread; and sleeving the anti-falling end hole 3-2 of the connecting sleeve 3 at the anti-falling neck part 4-2 of the leveling end plate 4, and then welding the anti-falling neck part 4-2 of the leveling end plate 4 and the bearing end plate 4-3 of the leveling end plate 4.
When the track structure needs to be transversely clamped and limited in the transverse deviation rectifying process of the ballastless track structure, the clamping device connected into a whole is placed between the counterforce structure and the track structure, the length of the clamping device is adjusted through a sleeve-screw rod structure formed by screwing the length adjusting sleeve 1 and the length adjusting screw rod 2, so that the bearing end plate 1-1 of the length adjusting sleeve 1 acts on the working surface of the counterforce structure, and meanwhile, the bearing end plate 4-3 of the leveling end plate 4 acts on the side surface of the track structure.
Two wrenches are respectively arranged on a bayonet 1-3 of the length-adjusting sleeve 1 and an outer hexagon head 2-2 of the length-adjusting screw rod 2, and the length and the clamping force of the clamping device are adjusted by manually applying force to the wrenches, so that the transverse clamping constraint of the ballastless track structure is realized.
When the working surface of the counter-force structure is not parallel to the side surface of the track structure at the corresponding position and forms a certain included angle, the spherical hinge structure formed by the spherical hinge 2-4 of the length-adjusting screw rod 2 and the spherical hinge base 4-1 of the leveling end plate 4 can automatically adjust the angle of the clamping device, so that the working surfaces of the bearing end plate 1-1 of the length-adjusting sleeve 1 and the bearing end plate 4-3 of the leveling end plate 4 are kept to be fully contacted with the counter-force structure and the track structure acting surface clamped at the two sides, the uniform stress is kept, and the concrete damage caused by the clamped structure and the bending damage of the clamping device due to the concentrated stress are avoided.
After the ballastless track structure of the deviation rectifying section permanently recovers the transverse stability of the track structure, the clamping device is disassembled to be used repeatedly.
