[0025] As attached Figure 1 To the attached Figure 4 As shown:

[0026] Embodiment 1: The utility model provides a rotation and turning device for an underground rubber-tyred vehicle, comprising an inclined plate 1, an adjusting mechanism 4 is provided inside the inclined plate 1, a base 5 is provided at the bottom of the adjusting mechanism 4, a limiting mechanism 3 is provided inside the adjusting mechanism 4, and a connecting seat 2 is provided at the top of the adjusting mechanism 4.

[0027] Furthermore, the adjustment mechanism 4 includes a fixed seat 401, a motor 402 is arranged in the fixed seat 401, a gear 404 is arranged on the top of the motor 402, a rotating plate 407 is arranged on the side wall of the gear 404, a limiting rod 406 is arranged at the bottom of the rotating plate 407, a first spring 405 is arranged in the limiting rod 406, and a roller 403 is arranged in the limiting rod 406.

[0028] Furthermore, the bottom of the motor 402 is fixed to the inside of the fixed base 401, one end of the motor 402 is rotatably connected to the gear 404, the side wall of the gear 404 is rotatably connected to the rotating plate 407, the limiting rod 406 is provided with several groups, the limiting rod 406 is fixed to the bottom of the rotating plate 407, one end of the first spring 405 is fixed to the inside of the limiting rod 406, and the roller 403 is clamped to the inside of the limiting rod 406 through the first spring 405.

[0029] Furthermore, the limiting mechanism 3 includes a push plate 301 , a second spring 304 is provided at the bottom of the push plate 301 , a rotating rod 303 is provided in the connecting seat 2 , and a limiting block 302 is provided at the top of the connecting seat 2 .

[0030] Furthermore, the rotating rod 303 is rotatably connected to the inside of the connecting seat 2, the bottom of the limit block 302 is fixed to the top of the connecting seat 2, the push plate 301 is rotatably connected to the outside of the rotating rod 303, and two groups of second springs 304 are provided. One end of the two groups of second springs 304 is fixed to the inside of the connecting seat 2, and the push plate 301 is rotatably connected to the inside of the connecting seat 2 through the second spring 304.

[0031] Furthermore, three groups of bases 5 are provided, the top of the base 5 is fixedly connected to the bottom of the fixing base 401 , and the bottom of the inclined plate 1 is clamped to the top of the fixing base 401 .

[0032] As can be seen from the above, by placing the inclined plate 1 on the top of the fixing seat 401, the inclined plate 1 is clamped on the side wall of the fixing seat 401 by utilizing the cooperation between the inclined plate 1 and the fixing seat 401, and the vehicle travels to the top of the connecting seat 2 through the inclined plate 1. When the vehicle travels to the top of the connecting seat 2, the wheel of the vehicle contacts one end of the push plate 301, and the vehicle moves the push plate 301 downward. The push plate 301 is rotated by the rotation connection between the push plate 301 and the rotating rod 303, and the other side of the push plate 301 is moved upward by utilizing the rotation of the push plate 301. The other side of the push plate 301 is cooperated with the limit block 302. , so that the wheels are fixed to the top of the connecting seat 2. It is worth noting that in order to achieve the fixing effect of the vehicle, when the rear wheel of the vehicle moves to the top of the push plate 301, the front wheel of the vehicle is located on one side of the push plate 301 on the other side, and the push plate 301 and the limit block 302 cooperate to achieve the fixing effect of the vehicle to prevent the vehicle from moving. By rotating the motor 402, the motor 402 drives the gear 404 to rotate when it rotates. At the same time, the side wall of the gear 404 and the rotating plate 407 are connected in a gear meshing manner, so that the gear 404 drives the rotating plate 407 to rotate, and the fixed connection between the rotating plate 407 and the limit rod 406 is used. Then, the rotating plate 407 drives the limiting rod 406 to rotate, and at the same time, the roller 403 at the bottom of the limiting rod 406 rotates along with the rotation of the rotating plate 407, thereby realizing the steering effect of the vehicle. When the vehicle is in a fully loaded state and needs to be turned, when the vehicle moves to the top of the connecting seat 2, the connecting seat 2 will move downward, and at the same time, when the connecting seat 2 moves downward, it pushes the rotating plate 407 to move downward, and the gear 404 is meshed with the rotating plate 407, so that the gear 404 moves inside the rotating plate 407. It is worth noting that in order to ensure the normal rotation of the rotating plate 407, the overall thickness of the rotating plate 407 is relatively thick, and the gear 404 The meshing parts are mostly embedded to ensure that the gear 404 drives the rotating plate 407 to rotate normally and prevents the rotating plate 407 from disengaging. The rotating plate 407 moves downward to push the limit rod 406 to move downward, so that the first spring 405 in the limit rod 406 is in a compressed state. The bottom of multiple groups of limit rods 406 are used to contact the top of the roller 403, so that the motor 402 drives the rotating plate 407 and the roller 403 to rotate at the same time, achieving the rotation effect of the vehicle. When the vehicle moves out of the top of the connecting seat 2, the tensile force of the second spring 304 is used to make the second spring drive the push plate 301 to rotate, which is convenient for subsequent use.

[0033] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the base 5 is provided in three groups, the top of the base 5 is fixedly connected to the bottom of the fixing seat 401, and the bottom of the inclined plate 1 is clamped to the top of the fixing seat 401.

[0034] From the above, it can be seen that by utilizing the cooperation between the base 5 and the inclined plate 1, the bottom of the base 5 contacts the ground, and the overall hardness of the fixing seat 401 is placed by the base 5. At the same time, the bottom of the inclined plate 1 contacts the ground, making the fixing seat 501 more stable as a whole, while ensuring the movement effect of the vehicle.
