[0020] Furthermore, a drive motor 102 is provided inside the driving vehicle 1, and the drive motor 102 drives the gear box 103. A drive shaft 1011 is coaxially connected between the driving wheels 101. The drive shaft 1011 passes through the driving vehicle 1 and the gear box 103 to provide power to the driving wheels 101.

[0021] Furthermore, the drive shaft 1011 is coaxially rotated with a sprocket, and the sprocket is driven by the chain 104, so that the arranged drive wheels 101 can rotate at the same speed.

[0022] Furthermore, the upper portion of the anti-tilt beam 404 is a transverse beam, the side portion of the anti-tilt beam 404 is tilted, and the side portion of the anti-tilt beam 404 and the fixed beam form a triangular structure, thereby increasing stability.

[0023] Furthermore, a reinforcement beam is provided in the middle of the anti-tilt beam 404 to ensure the stability of the anti-tilt beam 404 .

[0024] The upper part is the driving vehicle 1, and driving wheels 101 are arranged on both sides of the driving vehicle 1. The driving wheels 101 are coaxially linked through a driving shaft 1011. A driving motor 102 is provided inside the driving vehicle 1, and a gear box 103 is provided inside the driving vehicle 1. The driving motor 102 drives the driving shaft 1011 through the gear box 103. A sprocket is coaxially rotated on the driving shaft 1011, and the sprocket is chained by a chain 104. The lower end of the driving vehicle 1 is connected to a guide body 2, and a guide wheel 201 is arranged on the side end surface of the guide body 2. The guide wheel 201 rotates laterally. A stabilizing body 3 is provided at the lower end of the guide body 2, and an anti-wind wheel 301 is arranged on the side end of the stabilizing body 3. Figure 3 as well as Figure 4As shown, when the device of this scheme moves in the track, the driving wheel 101 moves at the upper end of the track as the main drive, the guide wheel 201 contacts the side end surface of the track, and the wind-resistant wheel 301 moves and contacts the bottom end surface of the guide rail. The lower end of the stabilizing body is connected with a suspension frame 4, and the upper two sides of the suspension frame 4 are fixed beams 401, and the fixed beams 401 are mirror-set. The upper part of the fixed beam 401 is provided with a shock absorber 402, and the outside of the shock absorber 402 is a shock-absorbing spring 4021. The bottom ends of the fixed beams 401 are connected with a connecting beam 403, and the rear of the fixed beam is provided with an anti-tilt beam 404, and the anti-tilt beam 404 is arched. The lower end of the anti-tilt beam (404) is connected to the fixed beam 401. The first hinge seat 405 is rotatably connected to the anti-roll beam 404, and the first hinge seat 405 is located below the shock absorber. The upper lateral part of the anti-roll beam 404 rotates through the second hinge seat 406 arranged with the lower end surface of the stabilizer 3, and in order to ensure that the anti-roll beam 404 and the stabilizer 3 remain relatively parallel, the second hinge seat 406 is in a downwardly extending state. The second hinge seat 406 and the stabilizer 3 are preferably in a vertical connection and fixed state. When in use, the bottom end of the connecting beam 403 is fixedly connected to the top of the rail vehicle body. When the vehicle is tilted by force, the connecting beam 403 receives the tilting force and transmits the tilting force to the upper fixed beam 401. The fixed beam 401 is vertically fixed to the stabilizer The bottom end of the anti-roll beam 404 will suppress the tilt of the vehicle body. During the force transmission process, the tilting force will be transmitted through the anti-roll beam 404. The side of the anti-roll beam 404 is tilted and arranged according to the fixed beam 401, and the upper part of the anti-roll beam 404 is rotatably connected to the bottom end of the stabilizing body 3 through the arranged second hinge seat 406. At this time, the fixed beam 401 and the side of the anti-roll beam 404 and the second hinge seat 406 and the end face of the stabilizing body 3 are rectangular, which is a stable structure. The upper part of the anti-roll beam 404 is connected in parallel with the stabilizing body 3, so the anti-roll beam 404 will counteract the tilting force based on the support of the stabilizing body 3. The first hinge seat 405 and the second hinge seat 406 described in this solution are connected The part can be a hinged seat with a rotating connection, a bearing seat with a rotating effect, or other stable structures that start the rotating connection. The outermost end of the second hinged seat 406 is aligned with the outermost end of the first hinged seat 405, so that the side of the anti-roll beam 404, the lower end face of the stabilizing body 3, and the fixed beam 401 form a rectangle, thereby enhancing stability. The function of the first hinged seat 405 and the second hinged seat 406 is to adjust. When the lateral wind force is large enough, one side of the driving wheel 101 will tend to tilt up. At this time, the wind-resistant wheel 301 on the left will be subjected to the downward force of the track, thereby avoiding the vehicle tilting caused by the tilting of one side of the driving wheel 101, thereby avoiding danger.
