[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] An auxiliary transport device for mining machinery includes a base plate 1, a first connecting frame 2 fixedly connected to the top of the base plate 1, a second connecting frame 3 provided above the base plate 1, the top of the first connecting frame 2 and the outer surface close to the second connecting frame 3 being open, the top of the second connecting frame 3 and the outer surfaces on both sides being open, and sliding grooves 9 being provided on the outer surfaces on both sides of the first connecting frame 2, the second connecting frame 3 being slidably connected to the two sliding grooves 9, and three drive wheels 4 being rotatably connected to the bottom of the base plate 1. The device also includes:

[0027] Two sets of limiting components are located between the first connecting frame 2 and the second connecting frame 3, and are used to fix the second connecting frame 3 and the first connecting frame 2.

[0028] The drive assembly, located on the outer surface of the base plate 1, is used to adjust the position of the second connecting frame 3 on the outer surface of the first connecting frame 2. By pushing or pulling the device through the first handle 7 or the second handle 8, the drive wheel 4 rolls, thereby realizing the movement and transportation of the device.

[0029] Furthermore, the limiting assembly includes limiting holes 10, fixing seats 11, and limiting posts 16. The outer surface of the first connecting frame 2 is provided with multiple equally spaced limiting holes 10. The outer surface of the second connecting frame 3 is fixedly connected to the fixing seats 11. The limiting posts 16 are movably connected inside the fixing seats 11. The limiting posts 16 penetrate the second connecting frame 3 and are inserted into the corresponding limiting holes 10. In the initial state, the locking posts 14 are located in the vertical direction of the limiting groove 12. The limiting posts 16 compress the springs 13 so that the limiting posts 16 are located inside the second connecting frame 3.

[0030] Furthermore, the limiting component also includes a limiting groove 12 and a snap-fit ​​post 14. The limiting groove 12 is formed on the outer surface of the fixed base 11. The snap-fit ​​post 14 is slidably connected inside the limiting groove 12. The snap-fit ​​post 14 is fixedly connected to the limiting post 16. When the second connecting frame 3 is adjusted to a suitable position, the snap-fit ​​post 14 moves within the limiting groove 12.

[0031] Furthermore, a spring 13 is elastically connected to the outer surface of the limiting post 16. The spring 13 is located inside the fixed base 11. The spring 13 has no compressive force, thereby driving the limiting post 16 to be inserted into the corresponding limiting hole 10, so as to achieve the stability of the connection of the second connecting frame 3.

[0032] Furthermore, the drive assembly includes a drive motor 17, a moving block 18, a threaded rod 19, and a rectangular groove 20. Two symmetrically distributed rectangular grooves 20 are opened on the top of the base plate 1. The moving blocks 18 are slidably connected inside the two rectangular grooves 20. The threaded rod 19 is rotatably connected inside one of the rectangular grooves 20. The threaded rod 19 is threadedly sleeved with the corresponding moving block 18. The tops of the two moving blocks 18 are fixedly connected to the bottom of the second connecting frame 3. The drive motor 17 is fixedly installed on the outer surface of the base plate 1. The output end of the drive motor 17 is fixedly connected to the threaded rod 19. When the drive motor 17 is started, it drives the threaded rod 19 to rotate. Since the threaded rod 19 is threadedly sleeved with the moving block 18, the moving block 18 will slide up and down in the rectangular groove 20 under the rotation of the threaded rod 19. The two moving blocks 18 move synchronously, driving the second connecting frame 3 to move in the two sliding grooves 9, thereby realizing the spatial adjustment between the second connecting frame 3 and the first connecting frame 2.

[0033] Furthermore, a box door 15 is hinged to the outer surface of the second connecting frame 3. Two symmetrically distributed first rings 21 are fixedly connected to the top of the box door 15. Two symmetrically distributed second rings 23 are fixedly connected to the outer surface of the second connecting frame 3. Insertion pins 22 are inserted between the first rings 21 and the second rings 23. The box door 15 is fixed to the second connecting frame 3 by inserting the insertion pins 22 into the first rings 21 and the second rings 23.

[0034] Furthermore, two symmetrically distributed cameras 5 are fixedly installed on the top of the base plate 1 near the second connecting frame 3. Two symmetrically distributed second handles 8 are fixedly connected to the outer surface of the base plate 1 near the first connecting frame 2. A first handle 7 is fixedly connected inside the base plate 1, located above the two second handles 8. A display screen 6 is fixedly installed on the outer surface of the base plate 1. The two cameras 5 are wirelessly connected to the display screen 6. The cameras 5 on the base plate 1 capture the situation during transportation in real time and transmit the images to the display screen 6 for operators to monitor and observe. Operators can make timely judgments and responses based on the images on the display screen 6.

[0035] Working principle: When the operator needs to use this auxiliary transportation device for mining machinery, in the initial state, the locking post 14 is located vertically in the limiting groove 12. The limiting post 16 compresses the spring 13, causing the limiting post 16 to be located inside the second connecting frame 3. The drive motor 17 is started, and the drive motor 17 drives the threaded rod 19 to rotate. Since the threaded rod 19 is threadedly connected to the moving block 18, the moving block 18 will slide up and down in the rectangular groove 20 under the rotation of the threaded rod 19. The two moving blocks 18 move synchronously, driving the second connecting frame 3 to move in the two sliding grooves 9, thereby realizing the adjustment of the space between the second connecting frame 3 and the first connecting frame 2. When the second connecting frame 3 is adjusted to the appropriate position, the locking post 14 moves in the limiting groove 12. At this time, the spring 13 is not compressed. The force then drives the limiting post 16 to insert into the corresponding limiting hole 10, thereby stabilizing the connection of the second connecting frame 3. The box door 15 is opened, and the items to be transported are placed into the space formed by the first connecting frame 2 and the second connecting frame 3. Then the box door 15 is closed, and the insert post 22 is inserted into the first ring 21 and the second ring 23, thereby fixing the box door 15 to the second connecting frame 3. The device is pushed or pulled by the first handle 7 or the second handle 8, which drives the wheel 4 to roll, thereby moving and transporting the device. The camera 5 on the base plate 1 captures the situation during the transportation process in real time and transmits the image to the display screen 6 for the operator to monitor and observe. The operator can make timely judgments and responses based on the image on the display screen 6. After arriving at the destination, the box door 15 is opened and the transported items are taken out.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
