[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1-Figure 4 The steel pipe column installation measurement positioning calibration device shown includes: a frame, a single prism 3 and a positioning component.

[0024] The frame includes a horizontal cross; a single prism 3 is arranged at the center of the cross, and the single prism 3 is used in conjunction with a total station to realize the installation and measurement of steel pipe piles; in this embodiment, the cross includes a horizontal cross-shaped base plate 1 and four fixed plates 2 distributed in a cross shape on the top of the cross-shaped base plate 1, and the single prism 3 is arranged at the bottom center of the cross-shaped base plate 1. The plate surface of the fixed plate 2 is perpendicular to the plate surface of the cross-shaped base plate 1. The fixed plate 2 and the end of the cross-shaped base plate 1 away from the single prism 3 are provided with an L-shaped tongue and groove 12, and the tongue and groove 12 is used to cooperate with the end of the steel pipe column. For example, when the steel pipe column is set upright and needs to be measured and positioned, the cross is placed on the top of the steel pipe column, so that the end of the cross-shaped base plate 1 is placed on the top of the steel pipe column, and the fixed plate 2 is located inside the steel pipe column. The fixed plate 2 is distributed along the radial direction of the steel pipe column and keeps a distance from the inner wall of the steel pipe column.

[0025] The positioning assembly includes two groups of telescopic inner support members, which are arranged to intersect each other in a horizontal plane; the center of the intersection and the center of the cross are on the same vertical line in space, and the vertical line is perpendicular to the board surface of the cross-shaped bottom plate 1.

[0026] Each group of telescopic inner support members includes a horizontally arranged first telescopic member, a horizontally arranged second telescopic member and a driving member; the driving member is used to drive the first telescopic member and the second telescopic member to synchronously telescope in the horizontal plane to move closer to or away from each other, and the distant ends of the first telescopic member and the second telescopic member intersect at a vertical line passing through the center of the cross along their telescopic directions, and are at the same distance from the vertical line, and the distant ends of the first telescopic member and the second telescopic member are supported on the inner wall of the steel pipe column.

[0027] Take the cross-shaped bottom plate 1 as an example, and regard it as a horizontal horizontal straight plate and a horizontal longitudinal straight plate connected together. Then the telescopic direction of the first telescopic member and the second telescopic member of the first group of telescopic inner support members is horizontal horizontal, while the telescopic direction of the first telescopic member and the second telescopic member of the second group of telescopic inner support members is horizontal longitudinal. The horizontal horizontal and the horizontal longitudinal intersect on the projection of the horizontal plane, and the vertical line perpendicular to the horizontal plane passing through the intersection also passes through the center of the cross and the center of the single prism 3.

[0028] The first telescopic member includes a first rack 4, and the second telescopic member includes a second rack 5; the length directions of the first rack 4 and the second rack 5 are parallel, and the driving member includes a driving gear 6, which is meshed with the first rack 4 and the second rack 5. By operating the driving gear 6 to rotate, the first rack 4 and the second rack 5 can be moved synchronously.

[0029] The telescopic inner support also includes a limiting guide 7, which is provided with a limiting channel; the length direction of the limiting channel is the same as the telescopic direction of the first telescopic member and the second telescopic member, and the first telescopic member and the second telescopic member pass through the limiting channel. The limiting guide 7 limits the moving path of the first telescopic member and the second telescopic member to ensure positioning accuracy.

[0030] The limiting guide 7 includes a U-shaped buckle, and the open end of the U-shaped buckle is connected to the fixed plate 2 to enclose and form a closed annular limiting channel. In some embodiments, the limiting guide 7 includes an L-shaped buckle, and the L-shaped buckle is connected to the cross to form a U-shaped limiting channel. Specifically, one end of the L-shaped buckle is connected to the fixed plate 2, and the other end is connected to the cross-shaped bottom plate 1. At least two limiting guides 7 are respectively matched on the first telescopic member and the second telescopic member.

[0031] The driving member includes a driving handle 8, a fixing block 9 and a locking nut 10. The driving handle 8 includes a rotating wheel and a driving rod. One end of the driving rod is connected to the center of the rotating wheel, and the other end passes through the fixing plate 2 and is connected to the fixing block 9. The fixing block 9 is fixedly connected to the cross-shaped bottom plate 1 of the cross. The driving gear 6 is fixedly mounted on the driving rod and is located between the fixing block 9 and the fixing plate 2. The fastening nut is threadedly connected to the driving rod. The fastening nut is located on the side of the fixing plate 2 facing away from the driving gear 6, and is used to fit tightly with the telescopic fixing plate 2 to limit the rotation of the driving rod. The telescopic inner support member also includes a rubber gasket 11, which is arranged at the far ends of the first telescopic member and the second telescopic member. The rubber gasket 11 is used to contact the inner wall of the steel pipe column to avoid damaging the steel pipe column.

[0032] When the rotating wheel is rotated, the driving rod is driven to rotate, thereby driving the driving gear 6 to rotate, driving the first rack 4 and the second rack 5 meshing therewith to move away from each other synchronously, so that the rubber gasket 11 located at the far ends of the first rack 4 and the second rack 5 is pressed against the inner wall of the steel pipe column. At this time, both sets of telescopic inner support members are pressed against the inner wall of the steel pipe column, and the single prism 3 located at the center of the cross is exactly in the center of the steel pipe column. By tightening the fastening nut to make it press against the fixing plate 2, the rotation of the driving rod is limited, and the position of the single prism 3 is also fixed to avoid errors in the rotation of the rotating wheel.

[0033] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
