[0037] The rotating base welding assembly 3 includes a base frame 301, a seat ring lower connecting plate 302 and a bottom plate 303. The base frame 301 is also a single-piece steel frame structure formed by welding a plurality of square tubes. The base frame 301 is a square body. A square seat ring lower connecting plate 302 is fixed to the top of the base frame 301, and a square bottom plate 303 is fixed to the bottom of the base frame 301.

[0038] The top of the inner ring gear 802 of the seat ring assembly 8 is fixed to the seat ring upper connecting plate 103 at the bottom of the platform frame 101 by circumferential bolts, and the bottom of the base body 801 of the seat ring assembly 8 is fixed to the seat ring lower connecting plate 302 at the top of the base frame 301 by circumferential bolts.

[0039] The climbing platform welding assembly 2 includes a slope platform 201, a connecting beam 202, a roller support plate I203, a support transition plate I204 and a triangular frame 205. There are two slope platforms 201 in total. The slope platforms 201 are in the shape of a right-angled tripod. A connecting beam 202 and a plurality of connecting angle steels are fixed between the two slope platforms 201. The connecting beam 202 is located at the lower position of the frontmost side between the two slope platforms 201; a horizontal roller support plate I203 is fixed to the front side of the connecting beam 202, and two equilateral angle steels are fixed to the bottom of the roller support plate I203 for support. An inclined support transition plate I204 is fixed on both sides of the roller support plate I203, and the two support transition plates I20 are symmetrical on both sides; a horizontally arranged triangular frame 205 is fixed to the front side of the upper end of the two slope platforms 201, and the triangular frame 205 is a right-angled triangle. The two triangular frames 305 are symmetrically arranged, and the hypotenuses of the two triangular frames 305 are opposite.

[0040] The roller support welding assembly 5 includes a connecting plate 501, a connecting angle steel 502, a square tube 503, a supporting angle steel 504, a roller support plate II 505, and a supporting transition plate II 506.

[0041] Adjustment gaskets 7 are provided on both sides of the bottom of the swivel base welding assembly 3; a ladder assembly 4 is fixed on one side of the swivel upper frame welding assembly 1 in the width direction; a triangular limit block 10 is fixed on both sides of the front end of the top of the swivel upper frame welding assembly 1.

[0042] During use, the vehicle is driven from the ground through the climbing platform welding assembly 2 to the slewing frame welding assembly 1, and the vehicle is limited by the two triangular limit blocks 10 at the front end. After the vehicle stops at the specified position, the same two triangular limit blocks 10 are used at the rear end of the rear wheel to limit the movement of the rear wheel, so as to limit the forward and backward movement of the vehicle during the north-seeking test to ensure safety; the output end of the motor reducer 9 drives the gear 6 to rotate through the gear transmission between the transition gears, and the gear 6 rotates the inner ring gear 802 through the meshing connection with the inner ring gear 802, and the inner ring gear 802 drives the slewing frame welding assembly 1 to rotate on the slewing base welding assembly 3 under the support of the bearing, and then the slewing frame welding assembly 1 drives the vehicle to rotate for north-seeking debugging.

[0043] When the vehicle goes from the climbing platform welding assembly 2 to the revolving frame welding assembly 1, there will be a downward pressure on the revolving frame welding assembly 1, forcing the revolving frame welding assembly 1 to tilt up. A roller 102 is installed at the middle position of the bottom of both ends of the platform frame 101 in the length direction. The two rollers 102 are respectively placed on the roller support plate Ⅰ203 of the climbing platform welding assembly 2 and the roller support plate Ⅱ505 of the roller support welding assembly 5; the roller 101 on this side of the roller support plate Ⅰ203 serves as a fixed support on the climbing platform welding assembly 2, and the roller support plate Ⅰ203 contacts the roller 101 to offset the pressure of the vehicle on the revolving frame welding assembly 1 to prevent the revolving frame welding assembly 1 from prying; the roller 101 on this side of the roller support plate Ⅱ505 serves as a fixed support on the roller support welding assembly 5, and the roller support plate Ⅱ505 contacts the roller 101 to offset the pressure of the vehicle on the revolving frame welding assembly 1.

[0044] The rotating frame welding assembly 1 serves as the rotating platform of the rotating north-seeking debugging device. The entire vehicle needs to be put on the rotating platform for testing. In order to better carry the load, the vehicle-carrying platform adopts a welded frame structure as the main body, and the main body is covered with a patterned steel plate 104; in order to ensure the safety of the vehicle when it is driven to the designated position of the platform, both sides of the rotating platform are welded to the platform frame 101 with a width of 900mm, and the middle position is left empty.

[0045] A seat ring upper connecting plate 103 is welded to the lower end of the platform frame 101. The seat ring upper connecting plate 103 is used to connect the inner ring gear 802 of the seat ring 8. The top of the inner ring gear 802 is connected to the seat ring upper connecting plate 103 with 45 M24 bolts; the base body 801 of the seat ring 8 and the seat ring lower connecting plate 302 on the slewing base welding assembly 3 are connected with 40 M24 bolts; in order to effectively bear the load of the entire gun, the base frame 301 of the slewing base welding assembly 3 also adopts a welded steel frame structure, and a bottom plate 303 is welded to the lower part of the base frame 301. The bottom plate 303 is connected and fixed to the ground with eight anchor bolts. At the same time, the slewing base welding assembly 3 is leveled by adjusting the gasket 7 to ensure that the entire vehicle is level on the slewing platform.

[0046] Since the rotating frame welding assembly 1 and the rotating base welding assembly 3 both adopt a welded frame structure with a seat ring 8 in the middle, the upper end face of the rotating frame welding assembly 1 is at a certain height from the ground, which is 516mm; the climbing platform 2 can enable the vehicle to go from the ground to the rotating frame welding assembly 1. Since the maximum climbing ability of the entire vehicle is 30°, two triangular slope platforms 201 with a slope of 20° are used on both sides of the vehicle. A connecting beam 202 is used to connect and position the two slope platforms 201. A steel plate is welded under the slope platform 201 and connected to the ground with four anchor bolts with anchor threads, and the climbing platform welding assembly 2 is as close to the rotating frame welding assembly 1 as possible. Since the rotating frame welding assembly 1 is rectangular, the rotation radius is the largest at the two diagonal end corners when rotating, which may interfere with the climbing platform welding assembly 2, so it is necessary to chamfer the end corners of the four corners of the rotating frame welding assembly 1 to reduce the maximum rotation radius and prevent interference with the climbing platform welding assembly 2 when rotating. At the same time, the inclined surfaces of the two triangular frames 205 at the front end of the climbing platform 2 fit with the chamfered surface at the end of the rotating frame welding assembly 1, so that they contact with the rotating frame welding assembly 1 to reduce the gap between them and prevent the wheel hub from being stuck in the gap; the climbing platform 2 facilitates the vehicle to go up and down the rotating frame welding assembly 1, and the rotating frame welding assembly 1, the rotating base welding assembly 3 and the climbing platform 2 are all welded with lifting ear plates.
