The positioning platform 2 is fixedly installed on the arc of the positioning hoop 1 by means of sleeving or bonding. There are at least two positioning platforms 2. The multiple positioning platforms 2 are evenly spaced along the outer periphery of the positioning hoop 1. The positioning platforms 2 are located at the equally divided points on the outer periphery of the positioning hoop 1. Specifically, in the embodiment of the present application, there are three positioning platforms 2, and the three positioning platforms 2 are respectively located at the trisection points on the outer periphery of the positioning hoop 1. A jacking member 3 is installed on each positioning platform 2. During the docking process of the vertical pipe 8 and the flange 9, the positioning hoop 1 fits the outer peripheral arc of the vertical pipe 8. The positioning hoop 1 is sleeved on the outer periphery of the vertical pipe 8. The multiple positioning platforms 2 are installed at the equally divided points of the positioning hoop 1. The multiple positioning platforms 2 are located in the same plane. The jacking members 3 are evenly spaced and installed on the outer periphery of the positioning hoop 1 along with the positioning platforms 2. The jacking members 3 abut against the bottom surface side of the flange 9. The flange 9 is driven to lift or lower on one side relative to the positioning hoop 1 through the jacking members 3. The overall height of the flange 9 is adjusted by the cooperation of the multiple jacking members 3 to level and position the flange 9, facilitating the docking of the vertical pipe 8 and the flange 9. After the docking is completed, the positioning hoop 1 is removed and sleeved on another vertical pipe 8, and the above process is repeated for the docking and positioning of other flanges 9. Compared with the prior art, the operation method of this device is simple and easy to implement, and can be reused, which not only reduces the difficulty of leveling the flange 9, but also improves the positioning efficiency.

In actual production applications, the number of limiting platforms 4 and elastic bands 5 matches the number of positioning platforms 2. One limiting platform 4, one elastic band 5 and one positioning platform 2 form an assembly unit. According to the outer circumference of the vertical pipe 8, multiple assembly units are selected to be spliced ​​to form the circumference of the vertical pipe 8.
