[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] See Figures 1-4 This embodiment provides a hydraulic lifting machine, including a base plate 1 with mounting holes. A lifting assembly 2 is disposed above the base plate 1. The lifting assembly 2 includes an outer sleeve 201, and an inner sleeve 202 is slidably connected to the inner surface of the outer sleeve 201. The outer sleeve 201 and the inner sleeve 202 are square in shape and made of metal. A hydraulic push rod 203 is fixedly connected to the top of the inner surface of the inner sleeve 202, and the lower end of the hydraulic push rod 203 is fixedly connected to the top of the base plate 1. A sliding groove 204 is provided on the front of the outer sleeve 201. The sliding groove 204 is through-hole, and a slider 205 is slidably connected to the inner surface of the sliding groove 204. The slider 205 is connected to the inner sleeve. The sleeve 202 is fixedly connected to the front, and the inner sleeve 202 is fixedly connected to the top of the inner sleeve 202. The cantilever 207 is hinged to the left side of the connecting block 206. The cantilever 207 can swing up and down on the left side of the connecting block 206. In its normal state, it is in a drooping state. The lifting assembly 2 also includes an electric winding device 208. The electric winding device 208 is specifically a winding drum. The winding drum is electrically controlled by a motor to rotate in order to wind up the rope and lift the goods. The electric winding device 208 is fixedly installed on the left side of the cantilever 207. The inner surface of the cantilever 207 is rotatably connected to a first pulley 3. A slot is provided below the cantilever 207 to accommodate the first pulley 3.

[0024] In practical use, the base plate 1 is first installed in the required location. When it is necessary to lift the goods, the hydraulic push rod 203 is activated to push the inner sleeve 202 to slide inside the outer sleeve 201. At this time, the slider 205 on the inner sleeve 202 will slide in the groove 204 on the outer sleeve 201. The rise of the inner sleeve 202 will drive the connecting block 206 to rise, and the rise of the connecting block 206 will drive the cantilever 207 to rise, thereby raising the electric winding device 208. After the cantilever 207 is raised, the electric winding device 208 is connected to the rope to lift the goods. The first pulley 3 is used to limit the rope to ensure stable lifting.

[0025] Example 2

[0026] See Figures 1-4 Based on Embodiment 1, a connecting component 4 is provided above the connecting block 206. The connecting component 4 includes a support plate 401, which is fixedly connected to the right side of the outer sleeve 201. A winch 402 is fixedly installed on the left side of the cantilever 207. A base is provided on the winch 402. A steel cable 403 is connected between the winch 402 and the support plate 401. A crank is provided on the winch 402 to drive the winch 402 to rotate. A supporting component 5 is provided below the steel cable 403. The supporting component 5 includes a support frame 501, which is T-shaped. The support frame 501 is connected to the connecting block 206. The support assembly 5 is fixedly connected to the steel cable 403. There are two support frames 501, and a second pulley 502 is rotatably connected between the two support frames 501. The second pulley 502 is used to support the steel cable 403 and is located below the steel cable 403. The support assembly 5 also includes a support column 503, which is located between the two support frames 501. The support column 503 is fixedly connected to the upper part of the connecting block 206. A baffle 504 is fixedly connected to the upper end of the support column 503 and is located above the second pulley 502 to prevent the steel cable 403 from coming off the second pulley 502.

[0027] When the above-mentioned equipment is used, when the hydraulic push rod 203 pushes the inner sleeve 202 to rise, it will also drive the winch 402 on the cantilever 207 to rise. At this time, the winch 402 will release the steel cable 403. When the inner sleeve 202 rises to the highest point, the steel cable 403 will straighten, thereby pulling the winch 402 to lift the cantilever 207 upward, so that the cantilever 207 can be supported to facilitate the lifting of goods. When the steel cable 403 is released, it will move on the second pulley 502. The second pulley 502 will cooperate with the baffle 504 to limit the steel cable 403 and prevent the steel cable 403 from falling off the second pulley 502.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
