A column lift

Abstract

The present invention discloses a column lift, which includes a base; a driving assembly; a lifting assembly; a stirring assembly; a protective assembly; a locking assembly; a discharge assembly; and a cleaning assembly. The driving assembly is started to drive the lifting assembly to operate, so that the lifting frame rises, and during the rising process, the stirring assembly is driven to be located in the lifting frame and stir the cement. When the lifting frame rises to the top, the stirring assembly continues to rise so that the stirring assembly is located at the top of the lifting frame. When the lifting frame rises to the top, the locking assembly and the protective assembly are opened. When the protective assembly is actuated, the discharge 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 assembly to clean the discharge 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 the cement.

Description

Technical Field

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

[0003] Most 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
