[0023] like Figure 1 As shown, a forced centering device for engineering measurement includes a body 1. Multiple threaded rods 2 are circumferentially hinged to the outer surface of the body 1. A threaded cylinder 3 is threadedly connected to the lower end of each threaded rod 2, and the other end of the threaded cylinder 3 is threadedly connected to a support rod 4. When used on uneven ground, the support rod 4 can be rotated to adjust the length of the legs formed by the support rod 4, threaded cylinder 3, and threaded rods 2, ensuring overall stability of the device when supported on uneven ground. When used on flat ground, a support cylinder 5 is threaded to the lower end of each support rod 4, and a support plate 6 is hinged to the bottom end of each support cylinder 5. The support plate 6 increases the contact area with the ground when placed on the ground. Additionally, a support column 7 is threaded into the central hole of the body 1, and an mounting component 8 is fixedly connected to the upper surface of the threaded support column 7. The height of the mounting component 8 can be adjusted by installing the support column 7, facilitating use by personnel and improving the practicality of the body 1.

[0024] like Figures 2-4As shown, the outer surface of the mounting piece 8 is radially slidingly inserted with a plurality of slide rods 9 in the circumferential direction, and the end of each slide rod 9 close to each other is fixedly connected with a rubber clamping piece 10, which is in contact with the gyroscope. In the process of clamping the gyroscope, the rubber clamping piece 10 can avoid damaging the gyroscope and can clamp the gyroscope while maintaining the stability of the gyroscope. The other end of each slide rod 9 is a large head, and a spring 11 is sleeved on the slide rod 9 between the large head and the outer surface of the mounting piece 8. The other end of each spring 11 is fixedly connected with the mounting piece 8. The spring 11 pushes the large head of the slide rod 9 away from the outer surface of the mounting piece 8 in the normal state, so that the plurality of rubber clamping pieces 10 are away from each other, and the clamping of the gyroscope can be released.

[0025] As shown in the figure, Figures 2-4 The outer surface of the mounting piece 8 is rotatably connected with a rotating frame 12, and the inner wall of the rotating frame 12 is fixedly connected with a plurality of arc-shaped extrusion blocks 13 distributed in a circle. The arc-shaped extrusion blocks 13 can push the plurality of slide rods 9 close to each other in the process of rotating the rotating frame 12, so that the plurality of slide rods 9 can push the rubber clamping pieces 10 to clamp the gyroscope. The outer surface of the rotating frame 12 is fixedly connected with a plurality of handles 14 distributed in a circle. The handle 14 can facilitate the user to rotate the rotating frame 12, thereby improving the convenience of the user when fixing the gyroscope. The lower outer surface of the mounting piece 8 is provided with a plurality of positioning grooves 15 distributed in a circle, and the bottom surface of the rotating frame 12 is fixedly connected with at least one elastic clamping piece 16. A plurality of elastic clamping pieces 16 are located in the corresponding positioning grooves 15. The cooperation of the elastic clamping piece 16 and the positioning groove 15 can limit the rotating frame 12 to avoid self-rotation of the rotating frame 12. The plurality of arc-shaped extrusion blocks 13 are in contact with the slide rods 9 close to them, and the plurality of springs 11 are in a compressed state. The arc-shaped extrusion blocks 13 can push the plurality of rubber clamping pieces 10 close to each other under the cooperation of the rotating frame 12, so that they can flexibly clamp the gyroscope.

[0026] Working principle and process:

[0027] 1) When using, first, when the gyroscope device is centered, the user drives the rotating frame 12 to rotate through the handle 14. In the process of rotating, the arc-shaped extrusion block 13 rotates and pushes the plurality of slide rods 9 close to each other, so that the plurality of rubber clamping pieces 10 can clamp the device to achieve the purpose of forced centering. By installing the elastic clamping piece 10, damage to the gyroscope during clamping can be avoided, and the gyroscope can be clamped while maintaining the stability of the gyroscope.

[0028] 2), when the equipment is completed, through the installation of elastic clamping piece 16 and the cooperation of positioning groove 15 can limit the rotation of rotating frame 12, avoid rotating frame 12 from rotating. Through the cooperation of supporting cylinder 5 and supporting plate 6 can be placed on the flat bottom, and can increase the contact area with the ground, so that the body 1 can be more stable. By installing threaded support column 7, the height of mounting piece 8 can be adjusted, which is convenient for the use of gyroscope. When the body 1 is placed on the uneven ground, the supporting cylinder 5 and the supporting plate 6 can be removed, and the length of the plurality of supporting rods 4 can be adjusted by rotating the threaded cylinder 3, so that the body 1 can be placed on the uneven ground, so that the body 1 can keep horizontal, and the bottom end of the supporting rod 4 can be inserted into the soil, so that the body 1 can be more stable, thereby improving the practicability of the body 1.
