[0003] Normal tank trucks are suitable for driving on flat roads, but transportation scenarios are diverse. When a tank truck enters a circular tunnel, only the corners of the wheels are in contact with the tunnel, and the contact area is too small. Driving in a circular tunnel will cause increased tire wear and even destructive damage. Utility Model Content

[0004] The purpose of the utility model is to provide a circular tunnel tank truck traveling chassis device in order to solve the deficiencies of the above-mentioned technology.

[0005] The camshaft is connected to the chassis by a hydraulic cylinder, and the hydraulic cylinder is connected to the hydraulic cylinder to drive the camshaft to move upwards to move the camshaft. The camshaft is connected to the chassis by a hydraulic cylinder. The hydraulic cylinder is connected to the chassis by a hydraulic cylinder.

The tire assembly includes an inner tire 3 and an outer tire 4. The inner tire 3 is located on both sides of the walking frame 2, and the outer tire 4 is fixedly installed on the outer side of the inner tire 3; the inner tire 3 and the outer tire 4 are driven forward by the driving device of the tanker body 1; the support assembly includes a hydraulic cylinder 5 and a lifting plate 6, and the lifting plate 6 is connected to the walking frame 2 through the hydraulic cylinder 5; a driving motor 7 is provided on the lifting plate 6, and the output shaft of the driving motor 7 is fixedly connected to one end of a threaded rod 8, and the other end of the threaded rod 8 is connected to the lifting plate 6 through a bearing seat 9; the threaded rod 8 is provided with a left-handed thread and a right-handed thread, and the left-handed thread and the right-handed thread are provided with a left-handed thread and a right-handed thread. Both are provided with a moving block 10, and the moving block 10 is provided with a threaded hole for cooperating with the threaded rod 8; when the threaded rod 8 rotates, the two moving blocks 10 move in opposite directions, so that the angle between the two support wheels 16 can be adjusted, and the angle can be adjusted according to actual conditions; the lifting plate 6 is provided with a through cavity 11, and two support rods 12 are provided in the through cavity 11. A rotating shaft 13 is passed through the support rod 12, and both ends of the rotating shaft 13 are connected to the inner wall of the through cavity 11 through support bearings 14; the top of the support rod 12 is connected to one end of the telescopic rod 15, and the other end of the telescopic rod 15 is hinged to the moving block 10.
