[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 7 The present invention provides a technical solution:

[0031] Example 1:

[0032] A portable verticality testing instrument for steel pipe columns is provided. The verticality testing instrument includes an upper positioning plate 1, a rotation detection component, and a lower positioning component 17.

[0033] An upper screw tube 4 is provided at the upper middle end of the upper positioning plate 1, and a lower extension tube 5 is provided at the lower middle end of the upper positioning plate 1. The upper screw tube 4 and the lower extension tube 5 are connected vertically. An adjusting screw 2 with a cone at the lower end is inserted into the upper screw tube 4. The lower extension tube 5 is inserted into the upper end cavity of the steel pipe column 6. A pair of interconnected inner arc plates 11 and outer arc plates 12 are symmetrically inserted into the lower extension tube 5. The inner arc plate 11 fits against the outer wall of the cone at the lower end of the adjusting screw 2, and the outer arc plate 12 is pressed against the inner wall of the steel pipe column 6. A pair of symmetrical through holes 34 are provided on the arc side wall of the lower extension tube 5. The inner arc plate 11 and the outer arc plate 12 are connected by a horizontal bar that slides through the through holes 34. A second spring 35 is sleeved on the horizontal bar and is pressed between the inner arc plate 11 and the inner wall of the lower extension tube 5.

[0034] By adjusting the screw 2 to rotate and compress, a lateral compression is formed on the inner arc plate 11, which in turn pulls the outer arc plate 12 to extend outward, so as to achieve automatic center alignment between the upper positioning plate 1 and the upper end of the steel pipe column 6. Under the rotation and advancement of the adjusting screw 2, the outer arc plate 12 is pressed onto the inner wall of the steel pipe column 6, thereby fixing the upper positioning plate 1 and achieving precise position installation.

[0035] The rotation detection assembly includes a rotating block 7, a laser 9, and a gear 21 driven by a motor 15. A pair of symmetrical rotating blocks 7 are rotatably mounted in the upper positioning plate 1. The laser 9 is mounted on the lower end face of the rotating block 7. The upper end of the rotating block 7 is fixedly connected to a lower collar 23. The lower collar 23 is sleeved on the arc-shaped outer wall of the upper screw tube 4. An upper collar 22 is provided at the upper end of the lower collar 23. A gear ring 26 that meshes with the gear 21 is provided on the outer wall of the upper collar 22.

[0036] The motor 15 drives the gear 21 to rotate, and the gear 21 pulls the gear ring 26 to rotate circumferentially on the outer wall of the upper screw tube 4, so as to adjust the rotating block 7 and the laser instrument 9 and realize the rotational detection of the laser instrument 9.

[0037] The lower positioning component 17 includes an outer ring 18, a clamping clamp 19, and a lower detection ring 20. The outer ring 18 is telescopically connected to the upper positioning plate 1 via a pull rope 13. The clamping clamp 19 is fixedly sleeved on the lower outer wall of the steel pipe column 6. The lower detection ring 20 is provided with a storage groove 29, and a roller 27 is provided at the lower end of the lower detection ring 20. A receiving plate 30 for receiving and recording the laser trajectory of the laser instrument 9 is provided in the storage groove 29.

[0038] The upper positioning plate 1 and the lower positioning component 17 are closed and fixed by the pull rope 13, and the device is connected and transported by the roller 27. By using the cooperation of the laser instrument 9 and the receiving plate 30, a pair of symmetrical arc-shaped laser rotation trajectories are formed on the receiving plate 30. The verticality of the circumferential angle of the steel pipe column 6 can be obtained by the offset of the arc-shaped laser rotation trajectory at the center.

[0039] Example 2:

[0040] Based on embodiment 1, in order to achieve the limited rotation of the rotating block 7, a pair of symmetrical arc-shaped rotating grooves 8 are provided on the upper end of the upper positioning plate 1. The rotating block 7 is rotatably installed in the rotating grooves 8. A horizontally extending connecting rod 25 is provided on the outer wall of the lower collar 23. The end of the connecting rod 25 is fixed to the upper end of the rotating block 7 by screws. The lower collar 23 and the upper collar 22 are fixedly connected by connecting bolts 24 distributed in a circumferential array. An extension plate is provided at the upper end of the upper screw tube 4. The motor 15 is fixedly installed on the extension plate.

[0041] The rotation angle of the rotating block 7 is limited by setting the rotating slot 8, so as to cooperate with the receiving plate 30 at the lower end.

[0042] Example 3:

[0043] Based on embodiment 2, in order to achieve automatic closing and fixing of the upper and lower components, the upper positioning plate 1 is provided with a pair of symmetrical through holes arranged vertically. A winch assembly 14 is provided on the outer side of the upper end of the through hole. The lower end of the pull rope 13 is fixed on the outer ring 18, and the upper end of the pull rope 13 extends along the through hole to the upper end of the upper positioning plate 1. The upper end of the pull rope 13 rotates and wraps around the winch assembly 14.

[0044] The winch assembly 14 is used to wind up and extend the pull rope 13, thereby achieving the winding up of the pull rope 13 during the storage process, so that the upper positioning plate 1 and the lower positioning assembly 17 are closed, and the laser instrument 9 is placed in the storage slot 29 to protect the detection device.

[0045] The hoisting assembly 14 is a motor-driven rotating roller, which is a mature existing technology and will not be described in detail.

[0046] Example 4:

[0047] Based on embodiment 3, in order to avoid the roller 27 affecting the detection, the clamping clamp 19 is composed of a pair of symmetrical arc-shaped clamping assemblies. The arc-shaped clamps are clamped onto the steel pipe column 6 and are connected by bolts. The clamping clamp 19, the lower detection ring 20 and the outer ring 18 are connected by tie rods distributed in a circumferential array. The lower end of the lower detection ring 20 is provided with a compression cavity 28. The roller 27 is rotatably mounted on the lifting frame 33. The lifting frame 33 is provided with a compression column 31. The lower end of the lifting frame 33 is pressed against the inner wall of the compression cavity 28 with a first spring 32. The upper end of the compression cavity 28 is provided with two sets of insertion holes. The upper end of the compression column 31 is directly opposite the insertion holes. The lower end of the rotating block 7 is provided with a pair of extension rods 10 directly opposite the insertion holes.

[0048] By setting the first spring 32, during the detection process, the return force of the first spring 32 causes the roller 27 to be housed in the squeezing cavity 28. During the housing process, as the upper positioning plate 1 and the lower positioning component 17 close, the extension rod 10 is inserted into the insertion hole and presses down on the squeezing column 31, so that the first spring 32 is compressed and the roller 27 is squeezed to the outside of the lower detection ring 20, thus facilitating transportation after housing. The first spring 32 is used to buffer the vibration during transportation.

[0049] Example 5:

[0050] Based on embodiment 4, in order to further improve the convenience of transportation, a pair of symmetrical hinge seats 16 are provided on the upper outer edge of the upper positioning plate 1. A pull handle 3 is rotatably installed on the hinge seat 16. By setting the rotatably installed pull handle 3, the pull handle 3 can be rotated laterally during the detection process to avoid affecting the detection. After the detection is completed, the device can be conveniently handled or transported by resetting the pull handle 3.

[0051] The laser device 9 is an existing device, and the receiving board 30 is a laser receiving board that displays the trajectory of the laser emitted by the laser device 9 on the display. This is a mature technology in the field and will not be described in detail here.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
