The support beam 516 is used to carry a positioning beam 520, and the link structure 518 specifically includes a cylinder, a hydraulic cylinder, etc. to adjust the position.

It can be understood that, in practical applications, there are usually multiple sets of positioning devices 1 and multiple sets of positioning beams 520 in the longitudinal direction to perform three-dimensional adjustment on the same side of the friction secondary steel plate 4, and two sets of positioning devices 1 in the lateral direction to perform three-dimensional adjustment on both side of the friction secondary steel plate 4 to ensure the adjustment consistency and concentricity of both side of the friction secondary steel plate 4, where the two sets of positioning devices 1 correspond to two opening sides of the u-shaped structure or the u-like structure in the lower pipeline beam 3, that is, the two opening sides are both connected to the upper pipeline beam through the friction secondary steel plate 4. As shown in fig. 4, when a plurality of sets of positioning devices 1 are required for the friction pair steel plates 4 on the same side, two adjacent plate beams 300 are connected by a connecting clamping plate 530.

In the actual adjusting process, the specific steps may be as follows:

firstly, the supporting sleeve plate 510 is assembled on the lower pipeline beam 3, and then the positioning beam 520 is arranged on the supporting sleeve plate 510 by using a crown block, wherein the positioning device 1 can be pre-installed below the positioning beam 520, or each component member can be sequentially assembled in a field installation manner, so that the positioning device 1 and the friction pair steel plate 4 are of an integral structure.

Secondly, adjusting the transverse adjusting assembly 100 to enable the friction pair steel plate 4 and the connecting pin shaft 140 on the same side to be on the same vertical line and at a target position so as to ensure the flatness and the evenness; adjusting the vertical adjusting assembly 200 to enable the single-side friction pair steel plate 4 to be at a target position and enable the double-side friction pair steel plates 4 to be at the same height; adjusting the longitudinal adjusting assembly 400 to enable the steel plate 4 of the single-side friction pair to be at a target position and enable hole positions on the steel plate 4 of the double-side friction pair to be concentrically aligned; and detecting the verticality of the friction pair steel plate 4, if the verticality is not vertical, if the connecting pin shaft 140 is not adjusted in place, adjusting the first transverse adjusting threaded part 130 and the second transverse adjusting threaded part 160, and if the connecting pin shaft 140 is adjusted in place, adjusting the second transverse adjusting threaded part 160 to enable the central line of the single-side friction pair steel plate 4 and the central line of the connecting pin shaft 140 to be on the same vertical line.

And finally, after the single-side friction pair steel plate 4 is adjusted, measuring the distance between the other side friction pair steel plate 4 by using the single-side friction pair steel plate 4 as a three-dimensional reference through a laser range finder, and enabling the geometric dimension and the form of the two to meet the requirements.
