Description

Technical Field

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

[0002] In the process of construction projects, lifting mechanisms are often required to lift construction materials to the construction floor, thereby ensuring the smooth progress of construction. Different lifting equipment is often required for building structures of different heights and structures, thereby ensuring the smooth progress of construction. High-rise buildings mostly transport construction materials through tower cranes or construction elevators, while for single-story or two-story buildings in rural areas, simple lifting equipment is often used to lift construction materials to the roof during construction, thereby ensuring the smooth progress of the construction process.

[0003] For example, the Chinese patent with the publication number CN215711322U proposes a hoist for construction engineering. The patent sets a base plate, a side baffle, a fixing rod, a plate slot and a lifting ring, so that when the hoist for construction engineering lifts steel bars, the steel bar material is clamped between the fixing rods, and the steel bar material can be lifted and lifted. When lifting construction sand and gravel materials, the side baffle is clamped to the fixing rod through the plate slot, so that the upper side of the base plate can form a space for holding sand and gravel, so that the equipment can be carried out through a single lifting frame, avoiding the increase in the cost of lifting equipment, so that the practicality of the hoist is guaranteed. Through the self-locking universal wheel, when the hoist is in use, the lifting frame is moved and used through the self-locking universal wheel after loading the material, so as to ensure the use effect. However, in this solution, since the goods are supported by the diagonal bracing cantilever and the handgrip rod, etc., after the goods are lifted, the handgrip rod needs to be manually rotated to move the goods and put the goods down. Since the goods may be heavy, it may be more labor-intensive, which may make it inconvenient to use and has certain limitations. Utility Model Content
