Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a vacuum loading bin lifting device. Background Art

[0002] The vacuum feeding device is a dust-free closed pipeline conveying equipment that uses vacuum suction to transport granular and powdered materials. It uses the air pressure difference between the vacuum and the ambient space to form gas flow in the pipeline, drive the movement of the powdered material, and thus complete the transportation of the powder. It can be moved as a whole according to actual needs. During workshop production, it is often necessary to transport bagged raw materials from low places to high places. Some use manual transportation, some use general lifting ropes, etc., all of which have high work intensity and low work efficiency; some use feeding devices, most of the existing feeding devices are relatively complicated, the feeding height is not easy to adjust, and the stability is poor during feeding.

[0003] In order to solve the above technical problems, the Chinese utility model patent with the authorization announcement number CN214360012U discloses a lifting and movable vacuum feeding device. The utility model can make the hand-cranked winch assembly drive the lifting sleeve to move up and down, thereby driving the vacuum feeding device to move up and down, so as to be suitable for feeding ends at different positions and different heights in subsequent processes, with a wider range of applications, providing convenience for people;

[0004] Although the technical solution provided by the utility model solves the problem that the loading height of the existing vacuum loading bin is difficult to adjust during use, the vacuum loading bin in the above solution is installed on a fixed frame, and the fixed frame is clamped on one side of the lifting device. When the height of the vacuum loading bin needs to be adjusted, the fixed frame needs to be clamped on the lifting device first. The clamping method will make the vacuum loading bin unstable during the lifting process, which is inconvenient in actual use. Utility Model Content

[0005] The purpose of the utility model is to provide a vacuum loading bin lifting device to solve the problems raised in the above background technology.

[0008] Beneficial effects:

[0009] The utility model provides a lifting shell on the mounting frame, and a lifting column which can slide up and down is slidably installed inside the lifting shell. When the height of the vacuum loading bin needs to be adjusted, the lifting column rises or falls, and the vacuum loading bin can be synchronously driven to rise or fall through the connecting plate, so as to conveniently and quickly adjust the height of the vacuum loading bin, and at the same time ensure the stability of the vacuum loading bin during the lifting process.
