In addition, all the coupling/connection relationships mentioned herein do not mean that the components are directly connected, but mean that a better coupling structure can be formed by adding or reducing coupling accessories according to specific implementation conditions.
Referring to fig. 1 and 2, an empty pile steel pipe column positioner, including the location bed frame, this location bed frame is provided with a plurality of locating platform 20, and each locating platform 20 is parallel arrangement from top to bottom in proper order, specifically speaking, in this embodiment, the location bed frame includes four stands 11, and locating platform 20 is total two, and four angular position of each locating platform 20 respectively with each stand 11 rigid coupling, anchor plate 12 is installed to each stand 11 bottom, when using empty pile steel pipe column positioner, each anchor plate 12 of accessible fixed is fixed.
Each positioning platform 20 is provided with an adjusting mechanism, and each adjusting mechanism comprises a cross rod assembly and a hoop assembly arranged on the cross rod assembly.
Each cross bar assembly comprises a first cross bar 31 and a second cross bar 32 parallel to each other. Each hoop component comprises two opposite positioning hoops 40, a positioning hole 61 for the steel pipe column 62 to pass through is arranged between the two opposite positioning hoops 40, a positioning surface for fitting the steel pipe column 62 is arranged in the middle of each positioning hoop 40, one end of each positioning hoop 40 is installed on the corresponding first cross rod 31 and can move along the length direction of the first cross rod 31, and the other end of each positioning hoop 40 is installed on the corresponding second cross rod 32 and can move along the length direction of the second cross rod 32. As shown in fig. 1, the first cross bar 31 of the upper positioning platform 20 is perpendicular to the first cross bar 31 of the lower positioning platform 20, and the second cross bar 32 of the upper positioning platform 20 is perpendicular to the second cross bar 32 of the lower positioning platform 20, that is, the hoop component movement adjusting direction of the upper positioning platform 20 is perpendicular to the hoop component movement adjusting direction of the lower positioning platform 20. Specifically, each positioning platform 20 is a square frame structure, and each positioning platform 20 includes a first beam 21, a second beam 22 perpendicular to the first beam 21, a third beam 23 perpendicular to the second beam 22, and a fourth beam 24 perpendicular to the third beam 23; in the upper positioning platform 20, two ends of the first cross bar 31 and two ends of the second cross bar 32 are respectively erected on the second beam 22 and the fourth beam 24; in the lower positioning platform 20, both ends of the first cross bar 31 and both ends of the second cross bar 32 are erected on the first beam 21 and the third beam 23, respectively.
Specifically, referring to fig. 3, each positioning hoop 40 includes an arc-shaped hoop arm 41 and adjusting seats disposed at two ends of the hoop arm 41, each adjusting seat includes a connecting plate 42 connected to the corresponding hoop arm 41 and a leveling plate 43 connected to the connecting plate 42, and each positioning surface is disposed on an inner side surface of the corresponding hoop arm. When using empty pile steel-pipe column positioner, transfer the back with steel-pipe column 62 along locating hole 61, through two staple bolt subassemblies adjustment steel-pipe column 62's position and straightness that hangs down, if only set up a staple bolt subassembly, need highly increasing staple bolt arm 41, otherwise be difficult to guarantee steel-pipe column 62's straightness that hangs down, still need be unanimous with the radian of the locating surface of staple bolt arm 41 and steel-pipe column 62 outer peripheral face simultaneously, otherwise the condition that the power of holding tightly is not enough appears easily. However, in this embodiment, the upper and lower positioning platforms 20 are two meters apart, that is, the upper and lower hoop assemblies are two meters apart, the two positioning hoops 40 of the upper positioning platform 20 tightly hold the steel pipe column 62, the clamping force direction is along the x-axis direction shown in fig. 1, the two positioning hoops 40 of the lower positioning platform 20 tightly hold the steel pipe column 62, and the clamping force direction is along the y-axis direction shown in fig. 1, even if the positioning surface of the hoop arm 41 is not consistent with the radian of the outer circumferential surface of the steel pipe column 62, the steel pipe column 62 can be positioned by the two positioning points of the upper positioning platform 20 and the two positioning points of the lower positioning platform 20, and the perpendicularity of the steel pipe column 62 can be adjusted.
Specifically, each level adjustment plate 43 is bolted to a corresponding first crossbar 31, each level adjustment plate 43 is bolted to a corresponding second crossbar 32, each level adjustment plate 43 is provided with at least one first connection through hole 51, and each first crossbar 31 and each second crossbar 32 are provided with a first oblong hole 52 that is matched with the corresponding first connection through hole 51.

Because the gravity of steel-pipe column is heavier, remove the steel-pipe column and move by the removal location hoop 40, it is comparatively difficult through manual operation, but set up each pneumatic cylinder 71 after, can adjust very conveniently.
In addition, the position of the cross bar assembly can be adjusted on the positioning platform 20, specifically, two ends of each first cross bar 31 and two ends of each second cross bar 32 are both connected with the corresponding positioning platform through bolts, at least one second connecting through hole 53 is respectively arranged at two ends of each first cross bar 31 and two ends of each second cross bar 32, second long round holes 54 matched with the second connecting through holes 53 are respectively arranged on each positioning platform 20, and the length direction of each second long round hole 54 on the same positioning platform is perpendicular to the length direction of each first long round hole 52 on the positioning platform. So, when can prevent that empty pile steel-pipe column from fixing a position, the dislocation is great, so also can adjust the horizontal pole subassembly, cooperates the staple bolt subassembly again, the position of adjustable locating hole. Of course, the adjustment can be performed by this method for steel pipe columns of different sizes. Of course, each first connecting through hole 51 may be disposed in an oblong manner, and in this case, the length direction of the first connecting through hole 51 is perpendicular to the length direction of the first oblong hole 52. Similarly, each second connecting through hole 53 may also be disposed in an oblong manner, and in this case, the length direction of the second connecting through hole 53 is perpendicular to the length direction of the second oblong hole 54.
When the empty pile steel pipe column positioning device is used, the concrete operation steps are as follows:
s1, fixing the empty pile steel pipe column positioning device;
s2, the steel pipe column 62 is lowered into the cast-in-place pile from the positioning hole 61 through a crane, and meanwhile, a plurality of lug plates are welded to the top of the steel pipe column 62, so that the steel pipe column 62 can be prevented from falling before adjustment;
s3, vertically releasing four dotted line marks on the steel pipe column 62 by using a measuring instrument (such as a total station) in advance, wherein the positions of the four dotted line marks are consistent with the positions of the positioning hoops 40 of the two positioning platforms 20, and the steel pipe column 62 is lowered to a set position, and at the moment, the steel pipe column 62 is still hoisted by a crane, and the position of the steel pipe column 62 is adjusted to enable the four dotted line marks to be overlapped with the positioning hoops 40;
and S4, moving each holding hoop 40, gradually holding the steel pipe column 62, paying attention to the positions marked by the four dotted lines and the verticality of the steel pipe column 62 in the process of adjustment, and finally holding the steel pipe column 62 by each holding hoop 40.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
