Description

Technical field:

[0001] The utility model relates to the technical field of lifting equipment, in particular to a hydraulic lifting machine. Background technology:

[0002] Ore dressing is the most important link in the whole mineral production process. Usually, physical or chemical methods are used to separate useful minerals from useless minerals (usually called gangue) or harmful minerals in mineral raw materials, or the process of separating multiple useful minerals is called ore dressing. In the ore dressing production process, a filter is needed to screen and separate the minerals in the slurry. The filter is placed with an ultrasonic generator, which is an iron box and is relatively heavy. Since the slurry contains acid and alkali substances, it may cause corrosion to the surface of the ultrasonic generator box. Therefore, when the filter is not working, a small hydraulic lift is usually used to lift the ultrasonic filter to a certain height, away from acid and alkali substances, to reduce the degree of corrosion to the ultrasonic generator box.

[0003] At present, the existing technical defects are: due to the large number of equipment on the ore dressing site, the existing small hydraulic hoists basically have large bottom support frames, occupy a large area when idle, and cannot save area for the site; secondly, the existing patent publication number is CN211255041U, which discloses a hydraulic hoist for mines. Although the equipment can adjust the inclination angle of the lifting rod to increase the lifting height, as the angle of the lifting rod increases, the center of gravity of the lifting will gradually shift toward the workbench direction, which has certain limitations and cannot ensure that the direction of the center of gravity of the lifting will not change while adjusting the angle.

[0004] Therefore, the present application proposes a new technical solution to solve the above-mentioned technical deficiencies. Utility model content:
