[0032] like Figure 1-Figure 8 As shown, the gyroscope installation and fixing device of the present invention includes a crossbeam 1, a support column 2 and a clamping claw 3.

[0033] The crossbeam 1 is a long strip plate-like structure with a through circular hole longitudinally arranged in the middle of the crossbeam, in which a cylindrical slider is installed, and there is a countersunk hole in the middle of the slider; there is a square tube at each end of the crossbeam, which can slide on the crossbeam to adjust the length of the crossbeam, and the bolts on the square tube are tightened to fix the square tube on the crossbeam.

[0034] The main body of the support column 2 is tubular, including a lower support column and an upper support column. The bottom of the main body of the support column is a square base, which is welded to the lower support column, and the upper support column is connected in series with the lower support column. The telescopic upper support column can roughly adjust the required support height, and the upper support column is locked by tightening the bolts on the upper end of the lower support column. There is a threaded hole on the top of the upper support column and a fine-tuning screw is installed. The locking nut on the fine-tuning screw is rotated to loosen it, and the wrench rod on the fine-tuning screw is pulled to rotate the fine-tuning screw up or down. The top of the fine-tuning screw is directly inserted into the slider countersunk hole in the beam without threads. The top of the fine-tuning screw and the slider countersunk hole are clearance-matched, and the top of the fine-tuning screw can rotate freely in the slider countersunk hole; the cylindrical slider can rotate in the circular hole of the beam to achieve the angle adjustment between the support column and the beam.

[0035] The clamping claw 3 is composed of a clamp and a claw. The clamp is mounted on the lower support column and can slide along the lower support column. Tightening the fastening bolts on the clamp can fix the clamp at a certain position of the lower support column. There is a rectangular boss on each side of the clamp, and a threaded hole is opened on the boss. The front end of the clamp has threaded holes on both sides, and the gyroscope is placed in the middle of the clamp and fixed by bolts; the rear end of the clamp has rectangular through holes on both sides, which cooperate with the bosses on both sides of the clamp, so that the clamp moves left and right along the boss to adjust the position of the gyroscope and constrain the clamp to rotate up and down. Tightening the fastening bolts of the clamp fixes the clamp on the clamp.

[0036] Working process of the gyroscope mounting and fixing device of the present invention:

[0037] First, confirm the installation position of the gyroscope in the car in advance. Place the support column on the floor at the Z axis of the gyroscope installation position or on the floor near the Z axis where the support column is convenient for placement; adjust the square tubes at both ends of the beam, such as Figure 3 As shown in the figure, make the crossbeam just against the roof and the upper edge of the second row of doors, and tighten the bolts on the square tube. Figure 4 As shown in the figure, fix the square tube on the crossbeam, pull the upper support tube column of the support column upwards and insert the fine-adjusting screw into the slider hole on the crossbeam, as shown in the figure. Figure 3 As shown; tighten the bolts on the upper end of the lower support column, as shown Figure 6 As shown, lock the upper support column; turn the wrench rod on the fine-tuning screw to make the fine-tuning screw rise and press against the crossbeam. After confirming that it has been tightened and the support column is not loose, tighten the locking nut on the fine-tuning screw. Figure 5 As shown; Slide and adjust the clamp on the lower support column to the height of the gyroscope to be installed, and tighten the fastening bolts on the clamp to fix the clamp on the lower support column, as shown. Figure 7 As shown in the figure, place the gyroscope in the claw and tighten the gyroscope fastening bolt on the claw slightly to prevent the gyroscope from falling off. Figure 7 As shown; adjust the claws so that the gyroscope coincides with the Z axis of the installation location, tighten the claw fastening bolts to fix the claws, as shown. Figure 7 As shown; after adjusting the gyroscope vertically, tighten the gyroscope fastening bolts on the clamping claws and the installation is complete.

[0038] The gyroscope installation and fixing device of the present invention has square tubes that can slide on the crossbeam at both ends to adjust the length of the crossbeam. A longitudinal through-hole is provided in the middle of the crossbeam, and a cylindrical slider is provided in the hole. A countersunk hole is provided in the middle of the slider, which is connected to the top of the fine-tuning screw on the support column. The support column is placed vertically on the floor inside the vehicle, and the height of the fine-tuning screw can be quickly and roughly adjusted by stretching the upper support column, so that the top of the fine-tuning screw is inserted into the hole of the slider on the crossbeam. The fastening bolt at the upper end of the lower support column is tightened to lock the upper support column, and the fine-tuning screw can be raised and lowered by turning the wrench rod on the fine-tuning screw. When the crossbeam is firmly tightened, the locking nut on the fine-tuning screw is tightened, and after the adjustment clamp is moved to the target position, the fastening bolt on the clamp is tightened, and the gyroscope is placed in the front end of the clamping claw, and the gyroscope fastening bolt is tightened. After the adjustment clamp is moved to the target position, the clamping claw fastening bolt is tightened to complete the installation of the gyroscope.
