Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1-5 The universal mining machine maintenance platform shown includes a base frame 1 and a support platform 2. The support platform 2 is positioned above the base frame 1. A lifting mechanism 3 is fixedly installed at the top of the base frame 1, and the support platform 2 is positioned at the top of the lifting mechanism 3. The lifting mechanism 3 includes structures such as hydraulic cylinders to adjust the height of the support platform 2. The top of the support platform 2 serves as a platform for fixed placement in the mine shaft. U-shaped frames 4 are fixedly connected to each of the four corners of the base frame 1. A rotating rod 5 is installed between two corresponding U-shaped frames 4, and the rotating rod 5 is rotatably connected to the U-shaped frame 4. Both ends of the rotating rod 5 are fixedly connected to casters 6.

[0023] In practical use, the mining machine is placed on the support platform 2, and the mining machine can be moved easily through the cooperation of the rotating rod 5, the moving wheel 6 and other structures; the lifting mechanism 3 is used to lift the support platform 2 to adjust the height of the platform, and the support platform 2 has a large area to accommodate mining machines of different sizes, achieving a universal effect.

[0024] Considering that if the positioning is only achieved by the casters 6, the positioning of the fixed base frame 1, support platform 2 and other structures may be unstable, a square frame 7 is set inside the base frame 1. An upper horizontal plate 11 is fixedly connected to the base frame 1, and a lower horizontal plate 12 is fixedly connected to the square frame 7. A hydraulic cylinder 13 is set between the upper horizontal plate 11 and the lower horizontal plate 12. The hydraulic cylinder 13 is electrically controlled. Side plates 14 are fixedly connected to both ends of the square frame 7. The side plates 14 are pressed and engaged with the corresponding rotating rods 5.

[0025] Guide components are provided at the four corners of the top of the frame 7. The guide components include support plates 8, slide grooves 9, and guide rods 10. The support plates 8 are fixedly connected to the inner wall of the base frame 1. The slide grooves 9 are opened on the support plates 8. The guide rods 10 are slidably disposed inside the slide grooves 9. The bottom end of the guide rods 10 is fixedly connected to the frame 7.

[0026] A slide rod 15 is slidably mounted on the side plate 14. The bottom end of the slide rod 15 is fixedly connected to a limit plate 16. A spring 17 is mounted on the slide rod 15. One end of the spring 17 is fixedly connected to the side plate 14, and the other end of the spring 17 is fixedly connected to the limit plate 16.

[0027] Specifically, when it is necessary to fix the platform position, the extension end of the hydraulic cylinder 13 is extended, which drives the frame 7 to move downward. The frame 7 abuts against the ground. Since the frame 7 has a large contact area, the positioning stability is improved, making the platform less prone to shaking and maintaining the stability of the platform. When the frame 7 moves downward, the guide rod 10 slides downward on the support plate 8, which improves the stability of the overall structure.

[0028] At the same time, the frame 7 drives the side plate 14 to move downward, the limiting plate 16 abuts against the rotating rod 5, the rotating rod 5 slides upward on the side plate 14 and compresses the spring 17 to contract, thereby preventing the rotating rod 5 and the moving wheel 6 from rotating.

[0029] By setting up structures such as the square frame 7 and the side plate 14, when the platform position needs to be fixed, the square frame 7 abuts against the ground. Since the contact area of ​​the square frame 7 is large, the positioning stability is improved, making the platform less prone to shaking. At the same time, it can position the rotating rod 5 and the moving wheel 6, maintaining the stability of the platform during use.

[0030] To increase the contact area between the limiting plate 16 and the rotating rod 5, the limiting plate 16 is arc-shaped, and the lower surface of the limiting plate 16 is a concave surface.

[0031] A limiting component is provided above the support plate 8. The limiting component includes a square groove 18 and a limiting post 19. The square groove 18 is opened through the side wall of the base frame 1. The limiting post 19 is slidably connected inside the square groove 18. The limiting post 19 cooperates with the corresponding guide rod 10.

[0032] During the lifting and lowering of the guide rod 10, the limiting post 19 is offset from the guide rod 10; when the frame 7 abuts against the ground, it pushes the limiting post 19 to move towards the guide rod 10, so that the limiting post 19 abuts against the top of the guide rod 10, thereby improving the stability of the guide rod 10 and the frame 7, and reducing the pressure on the hydraulic cylinder 13.
