Description

Technical Field

[0001] The invention relates to the technical field of building material transportation, in particular to a column lift. Background Art

[0002] Column lift is a commonly used transportation device in construction projects. It lifts and lowers workpieces at different heights through a slide that can slide along the height direction of the column. A large amount of cement is required in civil engineering, and workers often need to use column lifts when transporting cement.

[0003] Most of the existing column lifts do not have the function of automatic unloading when transporting cement to high places, and manual unloading is required, which not only wastes manpower but also reduces transportation efficiency to a certain extent. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0005] In view of the above problems and / or the problems existing in the existing column lifts, the present invention is proposed.

[0006] Therefore, the object of the present invention is to provide a column lift. During use, cement is poured into the lifting frame, and the driving component is started to drive the lifting component to operate, so that the lifting frame rises. During the rising process, the stirring component is driven to be located in the lifting frame, and the cement is stirred, so that the cement and water are fully mixed and the cement is prevented from hardening to a certain extent. When the lifting frame rises to the top, the stirring component continues to rise, so that the stirring component is located at the top of the lifting frame. When the lifting frame rises to the top, the locking component and the protective component are opened. When the protective component moves, the unloading plate is driven to flip over. The cement begins to fall due to its own gravity and exerts pressure on the flap. At this time, the flap flips and drives the cleaning component to clean the unloading plate and exerts thrust on the cement, further accelerating the unloading speed. After unloading is completed, the flap rebounds under the action of the spring, which saves manpower to a certain extent and increases the transportation efficiency of cement.
