Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a hoist. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. With the rapid development of society, the construction industry is also developing rapidly. At the same time, hoists are indispensable in construction projects. Hoists are devices that lift materials through transmission mechanisms.

[0003] In the prior art, there is a construction engineering hoist with the announcement number CN216188545U, whose technical solution includes: a base plate, a spiral conveying mechanism is fixed on the upper side of the base plate through a bracket, and a hopper is arranged on the spiral conveying mechanism. A driving motor for driving the central axis of the spiral blade of the spiral conveying mechanism to rotate is also fixed on the upper side of the bracket. When the driving motor works, the threaded rod rotates under the action of the pulley transmission mechanism, and cooperates with the moving block to move the lifting plate up to realize the tool transportation of dust-removing materials. However, there is a problem that the contact area between the ground and the hoist cannot be increased in the prior art construction engineering hoist, so that the hoist is prone to tipping over during the process of lifting the materials. For this reason, a hoist is proposed. Utility Model Content
