Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1

[0020] like Figure 1 As shown, an auxiliary measurement and positioning device for hollow welded spheres of a grid structure includes a circular bubble level 1, a first circular magnet 2, and a positioning target 3. The circular bubble level 1 is fixedly installed on the top of the first circular magnet 2, and the positioning target 3 is fixedly installed on the circumferential surface of the circular bubble level 1.

[0021] The device is attached to the top or bottom of the hollow welded sphere by the first circular magnet 2. The attraction of the first circular magnet 2 allows the device to be firmly fixed on the hollow welded sphere, facilitating measurement. Then, the position of the circular bubble level 1 is adjusted so that the bubble is centered, ensuring the horizontality of the device and thus improving the measurement accuracy. After ensuring that the device is horizontal, a total station is used for measurement. The positioning target 3 provides a clear observation point for the total station to determine the position of the hollow welded sphere and reduce the error of manual visual inspection.

[0022] Example 2

[0023] like Figures 2 to 3 As shown, an auxiliary measurement and positioning device for hollow welded spheres of a grid structure also includes a mounting base 4 and a fine-tuning structure. The mounting base 4 is located between a circular bubble level 1 and a first circular magnet 2. The circular bubble level 1 and the first circular magnet 2 are respectively fixedly installed at the top and bottom of the mounting base 4, and the fine-tuning structure is sleeved on the circumferential surface of the mounting base 4.

[0024] When the device is attached to the top or bottom of the hollow welded ball by the first circular magnet 2, the construction personnel cannot move the circular bubble level 1 to the designated position in one go due to the magnetic attraction. They need to manually adjust the position of the circular bubble level 1 repeatedly. During the adjustment, the position of the circular bubble level 1 is deviated due to the experience of the construction personnel and the magnetic attraction. At this time, a fine adjustment device can be set on the circumference of the mounting base 4 to assist the construction personnel in fine-tuning the position of the circular bubble level 1 and improving the measurement accuracy.

[0025] In this embodiment, the fine-tuning structure includes a retaining ring 5, a connecting block 6, a threaded rod 7, and a threaded sleeve 8. The retaining ring 5 is sleeved on the circumferential surface of the mounting base 4. The front end of the connecting block 6 is connected to the retaining ring 5. The front end of the threaded rod 7 is rotatably connected to the rear end of the connecting block 6. A threaded sleeve is sleeved on the threaded rod 7.

[0026] When the position of the circular bubble level 1 needs to be adjusted, the retaining ring 5 on the fine-tuning structure can be fitted onto the circumferential surface of the mounting base 4. By observing the position of the bubble in the circular bubble level 1, the retaining ring 5 is rotated with the axis of the circular bubble level 1 as the center, and the fine-tuning structure is adjusted to a suitable angle. The threaded rod 7 and the threaded sleeve rotate with the retaining ring 5. After the angle is adjusted, the construction personnel fix the threaded sleeve and rotate the threaded rod 7. The front end of the threaded rod 7 pushes the connecting block 6 to move, the connecting block 6 drives the retaining ring 5 to move, and the retaining ring 5 pushes the mounting base 4 to move. Under the magnetic attraction of the first circular magnet 2, the mounting base 4 moves along the spherical surface of the hollow welded ball, thereby realizing the fine-tuning of the position of the circular bubble level 1.

[0027] In a relatively specific embodiment, a groove 9 is provided on the circumferential surface of the mounting base 4, and the retaining ring 5 is fitted inside the groove 9.

[0028] The front end of the retaining ring 5 is open, which makes it easy for the retaining ring 5 to be fitted onto the mounting base 4. When fine-tuning is performed, the groove 9 on the mounting base 4 limits the retaining ring 5 and can effectively prevent the retaining ring 5 from falling off.

[0029] In this embodiment, the fine-tuning structure also includes an L-shaped plate 10, a sliding groove 11, a connecting rod 12, and a second circular magnet 13. There are two L-shaped plates 10, which are symmetrically distributed and fixedly installed at the rear end of the retaining ring 5. The sliding groove 11 is opened on the vertical section of the L-shaped plate 10. One end of the connecting rod 12 is sleeved in the sliding groove 11, and the connecting rod 12 and the sliding groove 11 slide in the height direction. The other end of the connecting rod 12 is fixedly connected to the connecting block 6. The top of the threaded sleeve is fixedly provided with a second circular magnet 13.

[0030] The L-shaped plate 10 is fixed to the rear side of the retaining ring 5. The vertical section of the L-shaped plate 10 is perpendicular to the circular bubble level 1. When fine-tuning the position of the circular bubble level 1, after the retaining ring 5 rotates around the axis of the circular bubble level 1 to adjust the angle of the fine-tuning structure, the construction personnel fix the threaded sleeve by adsorbing the second circular magnet 13 onto the surface of the hollow welded ball, and then rotate the screw to make the connecting block 6 push the retaining ring 5 to move the mounting base 4. The retaining ring 5 swings with the mounting base 4 around the center of the hollow welded ball, and the connecting rod 12 can move downward in the slide groove 11 to adapt to the displacement of the retaining ring 5 in the height direction, so as to realize the fine-tuning of the circular bubble level 1. The structure is simple, the operation is more convenient, and the construction efficiency is improved.

[0031] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
