Description

A connection device for tower crane attached to wall

Technical Field

The invention relates to the technical field of building construction, in particular to a connection device for attaching a tower crane to a wall.

Background Art

A tower crane is a rotating crane with a boom mounted on the top of a tall tower. It has a large operating space and is mainly used for vertical and horizontal transportation of materials and installation of building components in housing construction. It consists of three parts: a metal structure, a working mechanism, and an electrical system. A tower crane usually needs to be installed with an attached wall. A Chinese patent with application number 202120610794.9 discloses a "wall cleaning device for embedded parts of a tower crane wall, which mainly relates to the field of embedded parts setting of tower cranes. It includes a fixed assembly and a grinding assembly slidably arranged on the fixed assembly; the grinding assembly includes a grinding wheel and a motor, and the motor Connected to the grinding wheel, driving the grinding wheel to rotate. The grinding assembly is connected to a measuring assembly, and the measuring assembly is a surveying pull rod or an electric telescopic rod. The grinding assembly is slidably connected to the fixing device through a sliding part, and the sliding part is provided with a motor cavity for accommodating the motor. A shock-absorbing buffer assembly is provided at the connection between the motor output shaft and the grinding wheel. The beneficial effect of the utility model is that when the embedded parts of the tower crane wall need to be installed, the embedded parts can be fully contacted with the building wall, avoiding the embedded parts from being unable to fully contact with the wall due to the rough wall surface, resulting in dangerous problems such as loosening of the embedded parts. "

This technical solution only solves the problem that the embedded parts are prone to movement or the bolts are loose when the tower crane is attached to the wall. At present, when the tower crane is attached to the wall, connecting parts are usually embedded in the wall to connect the wall and the tower crane. However, a large amount of embedded parts work during the installation of the tower crane makes it difficult to control the labor cost. At the same time, when the tower crane is dismantled, the embedded parts left in the wall often take a lot of time to remove, and the wall after the embedded parts are removed often needs to be repaired, which increases the construction cost.
