Description

Technical Field

[0001] The utility model relates to a field, specifically a wheel-cranking device. Background Art

[0002] In mechanical transmission systems, pulleys are a common transmission component and are widely used in various mechanical equipment, such as automobiles, machine tools, agricultural machinery, etc. When maintaining equipment, replacing parts or troubleshooting, it is often necessary to remove the pulley from the shaft.

[0003] Current pulley removal methods mostly rely on manual operations, such as using hammers, crowbars and other tools to knock or pry. This method is not only inefficient, but also easily causes damage to the pulley and shaft, and even affects the overall performance and life of the equipment. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model provides a wheel lifting device.

[0005] The technical solution adopted by this utility model:

[0006] A pulley device includes a shaft and a base plate, a pulley is sleeved on the rear end outer wall of the shaft, the inner wall of the pulley has four spokes distributed at equal angles, the middle part of the front side wall of the base plate is fixedly connected to the outer shell end of the jack, the pump rod end of the jack corresponds to the end of the shaft, and there are U-shaped steel pipes above and below the jack. The right end of the U-shaped steel pipe is two parallel pipes, and the left end of the U-shaped steel pipe is closed. The right ends of the two U-shaped steel pipes pass through the top two corners and the bottom two corners of the base plate respectively, and the U-shaped steel pipe is gap-connected to the base plate. The outer wall of the right end of the U-shaped steel pipe has a thread, and the right end of the U-shaped steel is threaded with a nut, which abuts the rear side wall of the base plate, and the left end of the U-shaped steel passes around the outside of the spokes.

[0007] The center of the pulley is provided with a ferrule, the inside of the ferrule is sleeved with a bearing and the shaft, the ferrule is sleeved with the outer ring of the bearing, and the inner ring of the bearing is sleeved with the outer wall of the shaft.

[0008] Beneficial effects of the utility model:

[0009] The utility model adopts a simple mechanical structure, which is mainly composed of a base plate, a jack and a U-shaped steel. The operation is simple and quick, and no complicated tools or equipment are required. The pulley can be stripped off the shaft by the cooperation of the jack, the U-shaped threaded steel and the base plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figure 1-4 As shown: a wheel-lifting device, including a shaft 1 and a base plate 4, a pulley 2 is sleeved on the rear end outer wall of the shaft 1, the inner wall of the pulley 2 has four spokes 3 distributed at equal angles, the middle part of the front side wall of the base plate 4 is fixedly connected to the outer shell end of the jack 5, the pump rod end of the jack 5 corresponds to the end of the shaft 1, and there are U-shaped steel pipes 6 above and below the jack 5. The right end of the U-shaped steel pipe 6 is two parallel pipes, and the left end of the U-shaped steel pipe 6 is closed. The right ends of the two U-shaped steel pipes 6 respectively pass through the top two corners and the bottom two corners of the base plate 4, and the U-shaped steel pipe 6 is gap-connected with the base plate 4. The outer wall of the right end of the U-shaped steel pipe 6 has a thread, and the right end of the U-shaped steel 6 is threaded with a nut 7, which abuts on the rear side wall of the base plate 4, and the left end of the U-shaped steel 6 passes around the outside of the spoke 3.

[0016] The center of the pulley 2 is provided with a ferrule 8 , the shaft 1 is sleeved inside the ferrule 8 through a bearing 9 , the ferrule 8 is sleeved on the outer ring of the bearing 9 , and the inner ring of the bearing 9 is sleeved on the outer wall of the shaft 1 .

[0017] When in use, the right ends of the two U-shaped steels 6 pass through the top and bottom of the bottom plate 4 respectively, and pass around the outside of the spokes 3. The two ends are fixed to the rear side wall of the bottom plate 4 by nuts 7 to keep it stable.

[0018] Align the pump rod end of the jack 5 with the end of the shaft 1, and press the shaft 1 out of the hole of the bearing 9. Due to the function of the U-shaped steel pipe 6, they effectively limit the horizontal movement of the pulley, ensuring that the pulley can move along the direction of the shaft when subjected to thrust without deviation or rotation.
