A horizontally arranged gear 6 is arranged above the drive end of the motor reducer 9. The drive end of the motor reducer 9 drives the gear 6, which is coaxial with the intermediate bevel gear, to rotate through the meshing transmission between bevel gears. The bottom of the axle of the gear 6 is mounted on the base body 801 via a bearing, and the gear 6 meshes with the inner ring gear 802.

[0036] The end of the rotary upper welding assembly 1 is provided with an inclined climbing platform welding assembly 2, and the front end of the rotary base welding assembly 3 is provided with a roller support welding assembly 5, which supports the front end of the rotary upper welding assembly 1.

[0037] The rotary upper welding assembly 1 is a rectangular body with chamfered corners. The rotary upper welding assembly 1 includes a platform frame 101, rollers 102, a connecting plate 103 on the seat ring, and a patterned steel plate 104. The platform frame 101 is a single piece of steel frame structure welded from several square tubes. A roller 102 is installed at the middle position of the bottom of both ends of the platform frame 101 along its length. A rectangular connecting plate 103 on the seat ring is fixed at the center position of the bottom of the platform frame 101. Two patterned steel plates 104 along their length are fixed on both sides of the top of the platform frame 101, with the middle position left empty.

[0038] The rotating base welding assembly 3 includes a base frame 301, a seat ring lower connecting plate 302, and a base plate 303. The base frame 301 is also a single piece of steel frame structure welded from several 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 base plate 303 is fixed to the bottom of the base frame 301.

[0039] The top of the inner ring gear 802 of the seat ring assembly 8 is fixed to the upper connecting plate 103 of the seat ring at the bottom of the platform frame 101 by bolts in the circumferential direction, and the bottom of the base body 801 of the seat ring assembly 8 is fixed to the lower connecting plate 302 of the seat ring at the top of the base frame 301 by bolts in the circumferential direction.

[0040] The climbing platform welding assembly 2 includes a ramp platform 201, a connecting beam 202, a roller support plate Ⅰ203, a support transition plate Ⅰ204, and a triangular frame 205. There are two ramp platforms 201, which are right-angled triangular frames. A connecting beam 202 and several connecting angle steels are fixed between the two ramp platforms 201. The connecting beam 202 is located at the lower front of the two ramp platforms 201. A horizontal roller support plate Ⅰ203 is fixed to the front of the connecting beam 202. 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 to each side of the roller support plate Ⅰ203. The two support transition plates Ⅰ204 are symmetrical. A horizontally arranged triangular frame 205 is fixed to the front of the upper end of each of the two ramp platforms 201. The triangular frame 205 is a right-angled triangle. The two triangular frames 305 are symmetrically arranged, and their hypotenuses are opposite each other.

[0041] 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. One end of two symmetrically spaced connecting angle steels 502 is fixed to one side of the square tube 503 in the width direction, and the other end of the two connecting angle steels 502 is fixed to the connecting plate 501. A roller support plate II 505 is fixed to the other side of the square tube 503 in the width direction, and a supporting angle steel 504 is fixed to both sides below the roller support plate II 505. On both sides of the roller support plate II 505, two supporting transition plates II 506 are fixed on the square tube 503 in a left-right symmetrical and inclined arrangement.

[0042] Adjustment shims 7 are provided on both sides of the bottom of the rotating base welding assembly 3; a ladder assembly 4 is fixed on one side of the rotating upper frame welding assembly 1 in the width direction; a triangular limit block 10 is fixed on both sides of the top front end of the rotating upper frame welding assembly 1.

[0043] During use, the vehicle moves from the ground onto the climbing platform welding assembly 2 and onto the rotating upper frame welding assembly 1. The two triangular limit blocks 10 at the front limit the vehicle. After the vehicle stops at the designated position, the two triangular limit blocks 10 at the rear of the rear wheels limit the movement of the rear wheels, thereby limiting the forward and backward movement of the vehicle during the north-finding test and ensuring safety. The output end of the motor reducer 9 drives the gear 6 to rotate through the gear transmission between the intermediate gears. The gear 6 meshes with the inner ring gear 802, causing the inner ring gear 802 to rotate. The inner ring gear 802, supported by the bearing, drives the rotating upper frame welding assembly 1 to rotate on the rotating base welding assembly 3. The rotating upper frame welding assembly 1 then drives the vehicle to rotate for north-finding debugging.

[0044] When the vehicle moves from the climbing platform welding assembly 2 onto the slewing upper frame welding assembly 1, it exerts downward pressure on the slewing upper frame welding assembly 1, causing it to tilt upwards. A roller 102 is installed at the midpoint of the bottom of each end of the platform frame 101 along its length. The two rollers 102 are respectively placed on the roller support plate I 203 of the climbing platform welding assembly 2 and the roller support plate II 505 of the roller support welding assembly 5. The roller 101 on the roller support plate I 203 provides a fixed support to the climbing platform welding assembly 2, and the roller support plate I 203 contacts the roller 101 to offset the pressure of the vehicle on the slewing upper frame welding assembly 1 and prevent it from being pried open. The roller 101 on the roller support plate II 505 provides a fixed support to the roller support welding assembly 5, and the roller support plate II 505 contacts the roller 101 to offset the pressure of the vehicle on the slewing upper frame welding assembly 1.

[0045] The slewing upper welding assembly 1 serves as the slewing platform for the rotating north-finding debugging device. The entire vehicle needs to be mounted on the slewing platform for testing. In order to better bear the load, the platform for carrying the vehicle adopts a welded frame structure as its main body, and the main body is covered with patterned steel plates 104. In order to ensure the safety of the vehicle during the process of driving to the designated position on the platform, patterned steel plates 104 with a width of 900mm are welded to the platform frame 101 on both sides of the slewing platform, leaving the middle position empty.

[0046] 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 is connected to the seat ring lower connecting plate 302 on the slewing base welding assembly 3 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. A base plate 303 is welded to the lower part of the base frame 301. The base plate 303 is fixed to the ground with eight anchor bolts. At the same time, the slewing base welding assembly 3 is leveled by adjusting shims 7 to ensure that the entire vehicle is level on the slewing platform.

[0047] Since both the slewing upper frame welding assembly 1 and the slewing base welding assembly 3 adopt a welded frame structure, connected by the seat ring 8 in the middle, the upper surface of the slewing upper frame welding assembly 1 is at a certain height from the ground, which is 516mm. The climbing platform 2 allows the vehicle to move from the ground onto the slewing upper frame welding assembly 1. Since the maximum climbing ability of the entire vehicle is 30°, two triangular ramp platforms 201 with an inclination of 20° are used on both sides of the vehicle. The two ramp platforms 201 are connected and positioned by a connecting beam 202. A steel plate is welded to the bottom of the ramp platform 201 and connected to the ground by four anchor bolts with anchor threads. The climbing platform welding assembly 2 is placed as close as possible to the slewing upper frame welding assembly 1. Since the slewing upper frame welding assembly 1 is rectangular, the turning radius is largest at the two diagonal corners during rotation, which may interfere with the climbing platform welding assembly 2. Therefore, the corners of the four corners of the slewing upper frame welding assembly 1 need to be chamfered to reduce the maximum turning radius and prevent interference with the climbing platform welding assembly 2 during rotation. Meanwhile, the inclined surfaces of the two triangular frames 205 at the front end of the climbing platform 2 fit into the chamfered surface at the end of the slewing upper frame welding assembly 1, so as to reduce the gap between them and prevent the wheel hub from getting stuck in the gap; the climbing platform 2 facilitates the vehicle to get on and off the slewing upper frame welding assembly 1. The slewing upper frame welding assembly 1, the slewing base welding assembly 3 and the climbing platform 2 are all welded with lifting lugs.
