It is worth mentioning that the ground can be a base surface on two sides of the rail or a construction surface of the bridge and can also be a fixed object such as a protective wall. The left and right fixtures 100 and 200 may be installed along a line perpendicular to the length direction of the rail.
The left side of the rail expansion and contraction adjusting device 3 is installed in the single rail expansion and contraction adjusting device fixing groove 330 of the left support unit 300, and the left support unit 300 moves left and right in the horizontal direction on the corresponding left fixing member 100, so that the left side of the rail expansion and contraction adjusting device 3 can be driven to move left and right in the horizontal plane. Correspondingly, the right side part of the rail expansion and contraction regulator 3 is installed in the single-side rail expansion and contraction regulator fixing groove 330 of the right support unit, the right support unit moves left and right on the corresponding right fixing member 200 along the horizontal direction, and in this embodiment, a first transverse connecting rod 400 is further included between the left support unit 300 and the right support unit to connect the two units into a whole, so that the right side part of the rail expansion and contraction regulator can be driven to move left and right on the horizontal plane. And then can drive rail flexible adjustment ware 3 whole and remove about on the horizontal plane to adjust rail flexible adjustment ware 3 whole to suitable position, so that the rail flexible adjustment ware 3 of laying can whole adjust to suitable position. And then laid on the track bed 2.
In this embodiment, the length of the first transverse connecting rod 400 is adjustable, that is, the gauge between the left single-sided portion and the right single-sided portion of the construction supporting device 1000 for the rail expansion adjuster 3 laid by the construction supporting device 1000 for the rail expansion adjuster is adjustable, so that the rail expansion adjuster has various specifications, and the construction requirements under various standards are met. Or, when the rail telescopic adjusters 3 are hoisted by the hoisting tool, the gauge between the rail telescopic adjusters is adjusted in place by the first transverse connecting rod 400, and the influence on the gauge caused by the deformation during hoisting by the hoisting tool is avoided.
As an alternative to the present embodiment, the first transverse connecting rod 400 may include a sleeve fixedly connected to either one of the left and right supporting units 300 and 300, having a screw thread on a circumferential inner sidewall thereof, and a screw rotatably connected to the other one of the left and right supporting units 300 and 300. The axes of the screw and the sleeve are both arranged approximately horizontally, and part of the screw is connected in the sleeve in a threaded manner. When the first transverse connecting rod 400 needs to be adjusted, the screw rod is rotated.

So that when it is necessary to adjust the length of the first transverse bar 400, it is sufficient to rotate the connecting cylinder 420.
The movable connection of the left supporting unit 300 on the left fixing member 100 may be that the left supporting unit 300 horizontally slides on the left fixing member 100 through a guide rail, or that the left supporting unit 300 horizontally moves on the left fixing member 100 through a screw slider structure. However, this structure is relatively precise and is not suitable for use in construction sites. In order to facilitate assembly, disassembly and use on a track construction site, referring to fig. 1, in some embodiments, the rail expansion and contraction adjuster construction supporting device 1000 further includes a second transverse connecting rod 500, the second transverse connecting rod 500 is disposed between the left supporting unit 300 and the left fixing member 100, two ends of the second transverse connecting rod 500 are respectively connected to the left supporting unit 300 and the left fixing member 100, and a length of the second transverse connecting rod 500 is adjustable.

In this embodiment, the horizontal distance between the right fixing member 200 and the right supporting unit is adjusted by the third transverse connecting rod 600 having an adjustable length between the right fixing member 200 and the right supporting unit, thereby achieving the relative movement of the right supporting unit with respect to the right fixing member 200 in the horizontal plane. The third transverse connecting rod 600 of this structure is a rod member, thereby facilitating the assembly and disassembly of the supporting device during construction.
The third transverse link 600, in cooperation with the second transverse link 500, can integrally adjust the interval between the left support unit 300 and the right support unit as a whole with respect to the left and right fixtures 100 and 200. Therefore, the construction and adjustment of the steel rail telescopic regulator under various working conditions can be met through the set of supporting device, and the universality of the supporting device is realized.
In the process of constructing the rail expansion and contraction regulator 3, in order to further improve the construction accuracy of the rail expansion and contraction regulator 3, the height of the rail expansion and contraction regulator 3 needs to be further adjusted, so that the rail expansion and contraction regulator 3 is supported at a proper height by the rail expansion and contraction regulator construction supporting device 1000.
