DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1

[0041] See also Figures 1-11 The present invention provides a steering walking mechanism, comprising a connecting plate 1, a steering wheel 2 and a walking wheel 3 are provided below the connecting plate 1, and the walking wheel 3 is rotatably connected to another connecting plate 1;

[0042] It also includes a connecting rod 4 and a rotating plate 5 rotatably connected to the connecting plate 1. The bottom end of the rotating plate 5 is rotatably connected to the steering wheel 2. Connecting plates 6 are hinged between the two ends of the connecting rod 4 and the two rotating plates 5. An adjusting rod 7 is rotatably connected to the bottom of the connecting plate 1. The end of the adjusting rod 7 is rotatably connected to a sleeve 8 that slides with the connecting rod 4.

[0043] A driving wheel 9 rotatably connected to the connecting plate 1, wherein the outer edge of the driving wheel 9 is rotatably connected to a movable plate 10;

[0044] A corresponding shuttle rack includes the above-mentioned steering walking mechanism, and also includes a bottom support plate 19 and multiple columns 20. A cross bar 21 is provided between two adjacent columns 20 through a connecting piece. The cross bar 21 is connected and fixed to the bottom support plate 19, and the connecting plate 1 is connected and fixed to the cross bar 21 at the bottom. A support plate 22 is fixed to the bottom of the column 20 through a plug-in piece, and the bottom support plate 19 is used to store logistics items.

[0045] A movable support plate 23 is provided between the two uprights 20 through a connecting piece, and a plug-in plate 24 is provided between the two movable support plates 23. For some logistics items of different sizes, the height of the movable support plate 23 can be adjusted by adjusting the plug-in plate 24 and the connecting plate 1, thereby increasing applicability.

[0046] The bottom of the bottom support plate 19 is fixedly connected to an electric telescopic system 25, and the telescopic end of the electric telescopic system 25 is rotatably connected to a matching wheel 26;

[0047] This application is used when the shuttle rack needs to be turned and moved;

[0048] First, loosen the connector to lift the support plate 22 away from the ground, and the steering wheel 2 and the running wheel 3 touch the ground;

[0049] Then, by rotating the adjusting rod 7, the adjusting rod 7 is tilted, which drives the sleeve 8 to move, tilts the connecting rod 4, drives the two connecting plates 6 to rotate, and rotates the two rotating plates 5. The two steering wheels 2 rotating on the rotating plates 5 are tilted, and the tilting directions of the two steering wheels 2 are the same, thereby completing the steering of the steering wheels 2, that is, completing the steering adjustment before the shuttle rack moves;

[0050] After the steering is adjusted, the angle of the adjustment rod 7 is fixed;

[0051] Then the electric telescopic rod 15 is started, so that the telescopic end of the electric telescopic rod 15 reciprocates and retracts, and cooperates with the movable plate 10 to make the driving wheel 9 continuously rotate on the connecting plate 1 (rotate in the same clockwise direction). Through the cooperation of the bevel gear 16, the two steering wheels 2 with inclined angles roll, thereby completing the steering of the shuttle shelf. It is worth noting that the rolling directions of the two steering wheels 2 are opposite, which is more conducive to the steering angle;

[0052] By rolling the walking wheel 3 and the steering wheel 2, the shuttle rack completes the turn, stops the electric telescopic rod 15, and rotates the adjusting rod 7 so that the adjusting rod 7 is stuck in the U-shaped insertion rod 13;

[0053] Finally, the electric telescopic system 25 drives the mating wheel 26 to contact the ground and slightly supports the shuttle rack, so that the two steering wheels 2 are off the ground, while the two running wheels 3 are still in contact with the ground, pushing the shuttle rack to move, completing the position movement, and then sliding the support plate 22 to press against the ground;

[0054] Among them, a socket is opened on the support plate 22, and the shuttle shelf is fixed by inserting a pin into the socket and then into the reserved hole on the ground.

[0055] How to adjust the angle of the adjustment rod 7: The bottom of the connecting plate 1 is fixedly connected to a first fixing plate 11, and a U-shaped limiting rod 12 is inserted into the first fixing plate 11. The middle part of the adjustment rod 7 is rotatably connected to the connecting plate 1, and the U-shaped limiting rod 12 is fixedly connected to a U-shaped plug rod 13 and a plug rod 14 that plug into and cooperate with the adjustment rod 7;

[0056] By moving the U-shaped limiting rod upward along the first fixing plate 11, the plug rod 14 and the U-shaped plug rod 13 are separated from the first fixing plate 11, thereby releasing the restriction on the adjusting rod 7, wherein the bottom end of the U-shaped limiting rod 12 will not separate from the first fixing plate 11;

[0057] The adjusting rod 7 is tilted horizontally along the first fixed plate 11, so that the adjusting rod 7 drives the sleeve 8 to rotate horizontally to adjust the position. After the adjusting rod 7 is tilted, the U-shaped limit rod 12 is moved downward to make the adjusting rod 7 fit between the U-shaped limit rod 12 and the plug-in rod 14, thereby completing the fixation of the adjusting rod 7 after the angle is adjusted.

[0058] After the movable plate 10 is tilted, the subsequent electric telescopic rod 15 reciprocates and extends to adjust the clockwise direction of the rotation of the driving wheel 9. If the tilt angle of the movable plate 10 is not changed, the clockwise direction of the rotation of the driving wheel 9 remains unchanged. Then, when the steering wheel 2 is tilted to the left, the steering wheel 2 on the right rolls forward (the steering wheel 2 on the left rolls backward), which is convenient for turning the shuttle shelf. However, when the steering wheel 2 is tilted to the right, the steering wheel 2 on the right still keeps rolling forward (the steering wheel 2 on the left still keeps rolling backward), which will cause movement conflict.

[0059] When the adjusting rod 7 is tilted, it drives the sleeve 8 to make a circular motion. The sleeve 8 slides along the connecting rod 4, and at the same time, it causes the connecting rod 4 to tilt at a horizontal angle. The two connecting plates 6 rotate, causing the angles of the two rotating plates 5 to change, thereby rotating the steering wheel 2 to adjust the steering angle.

[0060] When the rotation angle of the steering wheel 2 is adjusted, and the angle of the movable plate 10 is also adjusted by the elastic rod 19, since the bottom of the connecting plate 1 is fixedly connected to the electric telescopic rod 15, the end of the electric telescopic rod 15 is rotatably connected to the movable plate 10. By starting the electric telescopic rod 15 (which can also be other telescopic power parts such as a cylinder), the telescopic end of the electric telescopic rod 15 reciprocates, thereby mobilizing the end of the movable plate 10 to reciprocate, and the other end of the movable plate 10 is rotatably connected to the edge of the driving wheel 9, so that the driving wheel 9 rotates at its original position on the connecting plate 1;

[0061] The rotating plate 5 is an L-shaped structure, and two mutually meshing bevel gears 16 are rotatably connected to the rotating plate 5. The central axis of one bevel gear 16 is fixedly connected to the central axis of the steering wheel 2, and the central axis of the other bevel gear 16 is fixedly connected to a driven wheel 17 rotatably connected to the connecting plate 1. A transmission toothed belt 18 is engaged between the driving wheel 9 and the driven wheel 17. The driving wheel 9 rotates in its original position on the connecting plate 1 (the clockwise direction is always consistent when rotating);

[0062] The driving wheel 9 rotates on the connecting plate 1, and drives the two driven wheels 17 to rotate through the transmission toothed belt 18. The rotating driven wheels 17 drive the two bevel gears 16 on the rotating plate 5 to rotate, thereby causing the steering wheel 2 to roll. The two rolling wheels rotate in opposite clockwise directions, one forward and the other backward, which is more conducive to the steering of the shuttle shelf.

[0063] Among them, the side of the transmission toothed belt 18 is pressed by a bonding plate connected and fixed to the connecting plate 1 (the bonding plate and the driving wheel 9 are squeezed respectively), and the bonding plate ensures that the transmission toothed belt 18 is always engaged with the driving wheel 9 for transmission.

[0064] Example 2

[0065] See also Figures 12-19 The second embodiment is a further supplement to the first embodiment. Specifically, it further includes a second fixing plate 9. A roller wheel 10 is rotatably engaged on the second fixing plate 9. The middle portion of the roller wheel 10 is movably engaged with the adjustment rod 7. The sleeve 8 is driven by the tilt adjustment rod 7 to rotate the connecting rod 4, thereby adjusting the inclination of the steering wheel 2.

[0066] Furthermore, limiting plates 17 that roll with the roller wheel 10 are fixedly connected on both sides of the second fixed plate 9. A movable ball 18 that slides with the adjusting rod 7 is movably embedded in the middle of the roller wheel 10. Due to the restriction of the limiting plates 17, the adjusting rod 7 tilts and drives the roller wheel 10 to roll along the first fixed plate 11. The roller wheel 10 slides along the adjusting rod 7, and the movable ball 18 slides along the adjusting rod 7. At the same time, the movable ball 18 rotates inside the roller wheel 10 to adjust the angle, and the corresponding adjusting rod 7 rotates horizontally at a certain angle relative to the roller wheel 10 to ensure that the roller wheel 10 rolls along the first fixed plate 11.

[0067] Furthermore, two elastic rods 19 are fixedly connected to the outer surface of the roller wheel 10 and press-fit with the movable plate 10. The second fixed plate 9 is provided with a sliding groove 20 that cooperates with the elastic rods 19. The rolling roller wheel 10 drives the elastic rods 19 to rotate.

[0068] Furthermore, a chute 22 is provided at the bottom of the driving wheel 9, and a slide post 23 connected and fixed to the movable plate 10 is movably fitted in the chute 22. The diameter of the slide post 23 is smaller than the width of the chute 22, and the width of the chute 22 is smaller than the width of the roller wheel 10, ensuring that the roller wheel 10 rolls on the first fixed plate 11 (the contact surface of the two is a rough surface). The elastic rod 19 rotates into the chute 22 without touching the first fixed plate 11, and will not affect the rolling of the roller wheel 10.

[0069] When the adjusting rod 7 is rotated, the roller wheel 10 rolls on the second fixed plate 9. The rotating roller wheel 10 tilts the movable plate 10, so that when the electric telescopic rod 15 is started later, the clockwise direction of the driving wheel 9 is adjusted to ensure that the tilted rotating wheel rotates to turn the shuttle rack;

[0070] When the elastic rod 19 contacts the movable plate 10, it drives the movable plate 10 to rotate, thereby causing the slide post 23 to move along the sliding groove 22, and the inclination angle of the movable plate 10 changes, wherein the diameter of the slide post 23 is smaller than the width of the groove 22, thereby ensuring that the slide post 23 will not be blocked when the inclination angle of the movable plate 10 is adjusted. After the elastic rod 19 converts the inclination angle of the movable plate 10, the elastic rod 19 continues to rotate and passes over the movable plate 10 (elastic bending), so that the end of the elastic rod 19 is located below the bottom surface of the movable plate 10, and the elastic rod 19 does not affect the subsequent reciprocating rotation of the movable plate 10 to drive the driving wheel 9 to rotate.

[0071] The telescopic end of the electric telescopic rod 15 moves back and forth, thereby mobilizing the end of the movable plate 10 to move back and forth. The other end of the movable plate 10 is pressed against the end of the slide groove 22 through the slide column 23, making a circular motion, so that the driving wheel 9 rotates in the original position. The outer surface of the slide column 23 and the contact surface of the slide groove 22 are friction surfaces, which reduce the sliding of the slide column 23 in the slide groove 22.
