[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0023] Example: Figure 1-4 As shown, this utility model provides a technical solution: a hoisting device for coal mining, including a mounting plate 1, a drive motor 2 fixedly installed inside the mounting plate 1, a mounting cylinder 3 fixedly connected to the output shaft of the drive motor 2, a drive motor 4 installed on the top of the mounting cylinder 3 by screws, a drive screw 5 fixedly connected to the output shaft of the drive motor 4, a moving block 6 connected to the outside of the drive screw 5 by threads, a moving groove opened at the position of the mounting cylinder 3 corresponding to the moving block 6, and the moving block 6 slidably connected inside the moving groove to ensure the stability of the movement of the moving block 6;
[0024] One end of the movable block 6 is welded with a mounting frame 7. Inside the mounting frame 7, one end is fitted with an electric push rod 8 by screws. One end of the electric push rod 8 is fitted with a movable rod 9 by screws. One end of the movable rod 9 is fitted with a mounting rod 10 by screws. Both ends of the mounting rod 10 are equipped with hooks 11.
[0025] The top two ends of the mounting cylinder 3 are fitted with placement boxes 12 by screws. The bottom end of the placement box 12 is fixedly connected to the discharge cylinder 13. One end of the discharge cylinder 13 is inside the moving groove. The end of the discharge cylinder 13 is conical. The sealing ball 15 is inside the end of the discharge cylinder 13, which facilitates sealing the end of the discharge cylinder 13 and makes it easy to push the sealing ball 15 to move. One end of the discharge cylinder 13 is fitted with a spring telescopic column 14 by screws. The sealing ball 15 is glued to one end of the spring telescopic column 14.
[0026] Both ends of the mounting rod 10 are fitted with spring dampers 16 by screws. The ends of two adjacent spring dampers 16 are connected by a movable plate 17. A threaded cylinder 18 is rotatably connected to one end of the movable plate 17, and a movable screw 19 is threadedly connected to the inside of the movable plate 17. A support plate 20 is fixedly connected to the bottom of the movable screw 19. A limit rod 21 is installed on the top end of the support plate 20 by screws. The limit rod 21 is slidably connected to the inside of the movable plate 17. A rotating sleeve is fixedly sleeved on the outside of the threaded cylinder 18. The outer diameter of the rotating sleeve is larger than the width of the movable plate 17 to ensure the stability of the movement of the support plate 20 and to facilitate the rotation of the threaded cylinder 18 by personnel.
[0027] After the personnel move the mounting plate 1 to a suitable position, they hang the item on the bottom of the hook 11. Then, they rotate the threaded cylinder 18, which drives the moving screw 19 to move inside the threaded cylinder 18, thereby moving the support plate 20. The longitudinal section of the support plate 20 is L-shaped. After moving the support plate 20 to a suitable position, the personnel move the support plate 20, which stretches the spring damper 16, so that the support plate 20 is at the bottom of the item, supporting the bottom of the item and ensuring the stability of the item during the hoisting process. Supporting the bottom of the item prevents the item from falling, thereby improving the safety of the item during hoisting. Furthermore, by adjusting the support plate 20, it can be used to support items of different sizes, expanding the application range of the hoisting equipment.
[0028] Then, the operator activates the electric push rod 8, which moves the moving rod 9 and the mounting rod 10 to move the item to the appropriate position. After that, the operator activates the drive motor 2 and the drive motor 4, which rotate the mounting cylinder 3 and move the moving block 6, thereby moving and rotating the item to the appropriate position. As the lifting device is used, the friction between the moving block 6 and the mounting cylinder 3 increases. The operator can drive the moving block 6 to move, causing the moving block 6 to squeeze the sealing ball 15, which in turn compresses the spring telescopic column 14, opening the discharge cylinder 13. This allows the lubricating oil inside the placement box 12 to enter the moving groove, lubricating the moving block 6, reducing its wear, and thus ensuring the use of the lifting device and extending its service life.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
