Description

Technical Field

[0002] Construction hoists are the most commonly used lifting equipment at construction sites. They are mainly used for transporting people and goods in high-rise building construction. Because of their reliable mechanical and electrical safety systems, they are safe and efficient vertical transportation equipment in construction. In order to ensure the stability of the construction hoist, a construction hoist arm (with wall bracket) is usually installed at intervals of 3-10.5 meters in the vertical direction. One end of the arm is connected to the elevator rail of the construction hoist, and the other end is connected to the building structure.

[0003] With the continuous changes in building forms, a large number of buildings have appeared in which the upper layers of the building structure are significantly inward compared to the lower layers, that is, the upper structure beams of the building structure are located inside the lower structure beams. Since the length of the attachment arm is fixed, when the attachment arm is connected to the upper structure, the distance between the attachment arm and the building structure may exceed the attachment distance of the attachment arm, and the attachment between the attachment arm and the building structure cannot be satisfied. In order to solve the above problem, an extended wall structure is generally added between the attachment arm and the building structure, and the attachment arm is connected to the building structure through the extended wall structure. However, the current extended wall structure is generally a fixed structure, and the length of the extended wall structure cannot be adjusted according to the wall distance between the attachment arm and the building structure, which limits the use of construction lifting.
