In this embodiment, the vehicle body 1 travels along the track 2, which improves the traveling accuracy, has a simple operation, and can also avoid the problem that a tire-type vehicle body is prone to deviation.

[0029] As an alternative solution, in this embodiment, the driving mechanism includes a motor 13 and a worm and worm gear reducer 4. The motor 13 is connected to the worm and worm gear reducer 4. The motor 13 and the worm and worm gear reducer 4 are both arranged on the vehicle body 1. The worm and worm gear reducer 4 is connected to the driving wheel 8. The motor 13 is communicatively connected to the control unit 5. The worm and worm gear reducer 4 can convert the vertical rotation of the motor 13 into horizontal rotation, saving layout space.

[0030] As an alternative solution, in this embodiment, a sprocket 7 transmission mechanism is arranged between the worm and worm gear reducer 4 and the driving wheel 8. The sprocket 7 transmission mechanism includes a chain 6 and two sprockets 7. The two sprockets 7 are respectively coaxially connected to the output shaft of the worm and worm gear reducer 4 and the rotating shaft 14 of the driving wheel 8. The chain 6 is wound around the sprocket 7. In this embodiment, the sprocket 7 connected to the output shaft of the worm and worm gear reducer 4 has a smaller radius than the sprocket 7 coaxially connected to the rotating shaft 14 of the driving wheel 8, which is convenient for transmitting a larger torque.

[0040] Embodiment 2

[0041] As Figures 3 to 4 shown, the usage process and principle of the track recycling mobile system in this embodiment are as follows: When used for the first time, first place the track 2, and then control the lifting mechanism 10 through the control unit 5 to adjust the position of the driven wheel 9 so that the driven wheel 9 falls on the lower side plate of the C-shaped track groove 15. The vehicle body 1 drives the driving wheel 8 to move on the track 2 through the sprocket 7 transmission mechanism, and the driven wheel 9 supports and follows. When the vehicle body 1 approaches the front end of the track 2, the limit switch 12 will be triggered. After the control unit 5 receives the signal transmitted by the limit switch 12, it will control the motor 13 to stop rotating. At the same time, it will control the support mechanism 11 to extend, and the lifting mechanism 10 to retract about 5 cm. While the track 2 is lifted, the support mechanism 11 also lands for support and lifts the vehicle body 1 up, so that the driven wheel 9 abuts against the upper side plate of the C-shaped track groove 15, and the driving wheel 8 always abuts against the top of the track 2. Finally, the track 2 is about 5 cm off the ground, so that the driving wheel 8 and the driven wheel 9 are respectively located on the upper and lower sides of the upper side wall of the C-shaped track groove 15, and can clamp the C-shaped track groove 15. At this time, control the motor 13 to reverse, and drive the guide rail forward through the rolling friction of the driving wheel 8. When the vehicle body 1 approaches the rear end of the track 2, the limit switch 12 will be triggered. After the control unit 5 receives the signal transmitted by the limit switch 12, it will control the motor 13 to stop rotating. At the same time, it will control the support mechanism 11 to retract, and the lifting mechanism 10 to extend about 5 cm, so that the driven wheel 9 falls on the lower side plate of the C-shaped track groove 15, start the motor 13, and repeat the cycle, and the vehicle body 1 can continue to move forward along the guide rail.

[0042] In this embodiment, the track recycling mobile system can be applied to the secondary lining trolley. Two vehicle bodies 1 are arranged on one guide rail. The length of the guide rail can be laid as needed, reused, and the cost can be reduced, and the construction period can be shortened.

[0043] In the present invention, specific examples are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
