[0022] Example 1, as shown in Figures 1, 2, 3 and 4, relates to a drive mechanism for an automatic walkway, including a mounting base plate 1. Each of the four corners of the mounting base plate 1 has a through-hole 2. Support frames 3 are fixedly mounted at both ends of the top of the mounting base plate 1. Main drive wheels 4 are symmetrically arranged between the two support frames 3. Movable sleeves 5 are fixedly mounted inside each of the two main drive wheels 4. Four sliding connecting blocks 6 are symmetrically fixedly mounted on the inner wall of the movable sleeves 5. A drive assembly 7 and an adjustment assembly 8 are fixedly mounted on the top of the mounting base plate 1, and both movable sleeves 5 are connected to the drive assembly 7 and the adjustment assembly 8.

[0023] The drive assembly 7 includes a support frame 9, which has an n-shaped structure. The support frame 9 is fixedly mounted on the top of the mounting base plate 1. A drive motor 10 is fixedly mounted on the top of the support frame 9. A drive main rod 11 is fixedly mounted on the output shaft of the drive motor 10. A brake 12 is mounted on the outside of the drive main rod 11 and is fixedly mounted on the top of the support frame 9. A reducer 13 is fixedly mounted on the top of the end of the support frame 9 away from the drive motor 10, and the end of the drive main rod 11 away from the drive motor 10 is fixedly connected to the input end of the reducer 13. A drive bevel gear 14 is fixedly installed on the top of the output shaft of the reducer 13. A transmission bevel gear 15 is meshed with the outer side of the drive bevel gear 14. A drive crossbar 16 is fixedly installed inside the transmission bevel gear 15. Both ends of the drive crossbar 16 are rotatably connected to the support frame 3. Two movable sleeves 5 are symmetrically slidably installed on the outer side of the drive crossbar 16. Two sets of sliding connection grooves 17 are symmetrically opened on the outer side of the drive crossbar 16. There are four sliding connection grooves in each set. The sliding connection block 6 is slidably installed inside the sliding connection groove 17.

[0024] The adjusting assembly 8 includes a strip frame 18, one side of which is open. A support base 19 is fixedly installed at the bottom of the strip frame 18, and the bottom of the support base 19 is fixedly connected to the top of the mounting base plate 1. An adjusting motor 20 is fixedly installed on one side of the strip frame 18. A bidirectional screw 21 is rotatably installed inside the strip frame 18, and the output shaft of the adjusting motor 20 movably passes through one side of the strip frame 18 and is fixedly connected to one end of the bidirectional screw 21. Threaded sleeves 22 are symmetrically threaded inside the strip frame 18 and located outside the bidirectional screw 21. The threaded sleeves 22 are close to one side of the open structure of the strip frame 18. A movable strip plate 23 is fixedly installed on the side. A positioning slider 27 is fixedly installed on the side of the threaded sleeve 22 away from the movable strip plate 23. A positioning groove 28 is symmetrically opened through the side of the strip frame 18 away from its open structure, and the positioning slider 27 is slidably installed through the inside of the positioning groove 28. Movable rods 24 are fixedly installed on the tops of the two movable strip plates 23 on the sides away from each other. A movable frame 25 is fixedly installed at the end of the movable rod 24 away from the movable strip plate 23. A connecting bearing 26 is fixedly installed through the end of the movable frame 25 away from the movable rod 24, and the movable sleeve 5 is rotatably installed inside the connecting bearing 26.

[0025] During use, the interaction of the mounting base plate 1, fixed mounting hole 2, main drive wheel 4, movable sleeve 5, sliding connecting block 6, drive assembly 7, and adjustment assembly 8 allows the distance between the two drive wheels on the automatic walkway to be adjusted according to the actual width of the automatic walkway, reducing the limitations of the drive mechanism for automatic walkways and thus achieving better practicality. Furthermore, the interaction of the positioning slider 27 and positioning groove 28 ensures better stability when the threaded sleeve 22 moves, thereby ensuring that the adjustment assembly 8 can work stably.

[0026] Working principle: During operation, the mounting base plate 1 is first fixedly installed using fixing bolts that match the diameter of the fixing mounting hole 2. Then, the adjusting motor 20 is started to drive the bidirectional screw 21 to rotate. The bidirectional screw 21 drives the two threaded sleeves 22 to move away from each other. The threaded sleeves 22 drive the positioning slider 27 to slide inside the positioning groove 28, which can ensure better stability of the threaded sleeves 22 during movement. At the same time, the threaded sleeves 22 drive the movable plate 23 to move, the movable plate 23 drives the movable rod 24 to move, the movable rod 24 drives the movable frame 25 to move, and the movable frame 25 drives the movable sleeve 5 to move through the connecting bearing 26. The movable sleeve 5 drives the main drive wheel 4 to move. At this time, the two main drive wheels 4 move away from each other. After the distance between the two main drive wheels 4 reaches the required width of the automatic walkway, the adjusting motor 20 is stopped. In this way, the distance between the two drive wheels on the automatic walkway can be adjusted according to the actual width of the automatic walkway during use, reducing the limitations of the automatic walkway drive mechanism and thus facilitating better practicality.

[0027] Then, during use, the drive motor 10 is started to drive the drive main rod 11 to rotate. The drive main rod 11 drives the reducer 13 to work. The reducer 13 drives the drive bevel gear 14 to rotate. The drive bevel gear 14 drives the transmission bevel gear 15 to rotate. The transmission bevel gear 15 drives the drive crossbar 16 to rotate. Under the interaction of the sliding connecting groove 17 and the sliding connecting block 6, the drive crossbar 16 drives the movable sleeve 5 to rotate inside the connecting bearing 26. The movable sleeve 5 drives the main drive wheel 4 to rotate. The main drive wheel 4 then drives the automatic walkway to work through the transmission structure connected to it.

[0028] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
