[0020] The following embodiments will be described in detail with reference to the accompanying drawings. Similar or identical parts are denoted by the same reference numerals in the drawings and descriptions. In actual applications, the shape, thickness, or height of each component may be enlarged or reduced.

[0021] Example

[0022] See also Figures 1 to 4 In the embodiment of the utility model, the automatic lifting machine includes a base 1, a plurality of support rods 2 are evenly arranged on the top of the base 1, a top plate 3 is arranged at the top end of the support rod 2, and a plurality of groups of support plates 4 are evenly arranged on the top plate 3. A winding roller 5 is provided on the support plate 4 through a rotating shaft, and a slide groove is also provided on the support rod 2. A lifting plate 11 is slidingly provided in the slide groove, and a pull rope 10 is wound around the winding roller 5. The other end of the pull rope 10 is connected to the lifting plate 11. When it is necessary to lift an object, the staff places the object on the lifting plate 11. At this time, the pull rope 10 can be reeled in by the winding roller 5, thereby driving the lifting plate 11 to move up and down, so that the device can lift the object that needs to be lifted.

[0023] The top plate 3 is also provided with a double-axis self-locking motor 9, and a second bevel gear 8 is provided on the power output shaft of the double-axis self-locking motor 9 through a coupling. A bevel gear column 7 is also provided on the top of the top plate 3 through a fixed block. The second bevel gear 8 is engaged with one end of the bevel gear column 7. The end of the rotating shaft of the winding roller 5 is connected with a first bevel gear 6 through a key connection. The first bevel gear 6 is engaged with the other end of the bevel gear column 7. At this time, starting the double-axis self-locking motor 9 can drive the winding roller 5 to rotate through the second bevel gear 8, the bevel gear column 7 and the first bevel gear 6, so that the lifting plate 11 can lift the object, thereby ensuring the lifting efficiency of the elevator.

[0024] The lifting platform 11 is also provided with a cavity inside, and a slide rail 12 is provided in the cavity. Two front and rear extension plates 13 are slidably provided on the slide rail 12. Under the action of the extension plate 13, the width of the lifting platform 11 can be extended, so that the elevator can better meet the lifting work of objects of different sizes, thereby improving the applicability of the device. A limit plate is also provided on the side wall of the extension plate 13. Under the action of the limit plate, objects on the lifting platform 11 can be restricted, reducing the occurrence of objects falling off, thereby ensuring the efficiency of the use of the elevator. A bidirectional screw 14 is also rotatably provided inside the lifting platform 11, and the bidirectional screw 14 passes through the front and rear extension plates 13 and is threadedly connected to the front and rear extension plates 13. At this time, rotating the bidirectional screw 14 can drive the front and rear extension plates 13 to move, thereby adjusting the width of the lifting platform 11, thereby making the device better meet the needs of actual use and ensuring the quality of use of the elevator.

[0025] A shell 15 is also provided on the outer wall of the front side of the lifting plate 11, and the bidirectional screw 14 passes through the side wall of the shell 15 and extends to the inside of the shell 15. A worm gear 16 is also provided on the bidirectional screw 14 inside the shell 15 through a key connection. A worm 17 is also rotatably provided inside the shell 15, and the worm 17 and the worm gear 16 are meshed with each other. At this time, rotating the worm 17 can drive the bidirectional screw 14 to rotate through the worm gear 16, thereby moving the front and rear extension plates 13, thereby enabling the hoist to better lift objects of different sizes, thereby improving the applicability of the hoist. In addition, because the worm gear 16 and the worm 17 have a self-locking function, the position of the extension plate 13 after adjustment can be limited, thereby ensuring the efficiency of the lifting plate 11. A rotary handle is also provided at the outer end of the worm 17, and the worm 17 can be driven to rotate by rotating the rotary handle, thereby adjusting the position of the extension plate 13.

[0026] When the lifting device is in operation, the lifting roller 11 is rotated to move up and down in the groove of the support rod 2, thereby realizing the lifting and lowering of the object. When the object to be lifted is large in width, the staff can turn the handle to drive the two-way screw 14 to rotate through the worm gear 17 and the worm gear 16, thereby adjusting the spacing between the front and rear extension plates 13, so that the width of the lifting plate 11 can better meet the requirements of holding objects of different sizes, thereby improving the applicability of the lifting machine. Because the worm gear 16 and the worm gear 17 have a self-locking function, when the handle stops rotating, the position of the extension plate 13 will be fixed, ensuring the stability of the lifting plate 11 after the width adjustment, and under the action of the upper limit plate on the side wall of the extension plate 13, the position of the object on the lifting plate 11 can be limited, reducing the risk of the object falling off and ensuring the efficiency of the lifting machine.
