Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the invention.

However, due to the large general structure of the hoisting device, it is difficult to ensure that the profile is adjusted to a suitable angle, especially when the profile is adjusted to a small angle.

In order to solve the problems in the prior art, the invention provides a hoisting device for a special-shaped building piece structure. As shown in fig. 1, the present application provides a hoisting device for building a special-shaped member structure, comprising: a lifting frame 10 and an adjustment assembly 20.

and step 3: the movable cars are linked, the first motor car slides on the first slide rail, the second motor car slides on the second slide rail, and the first motor car and the second motor car horizontally move to adjust the angle and the position of the building special-shaped part so that the building special-shaped part is butted with the installation station;

and 4, step 4: in the linkage process of the moving vehicle, when a pressure sensor on the first motor car detects pressure, the driving assembly on the first motor car stops running, the driving assembly on the second motor car starts running and drives the second moving vehicle to move along the second sliding rail, and the second motor car pulls the first motor car to move reversely by adjusting the cross rod;

and 5: when the pressure sensor on the second motor car detects pressure, the driving assembly on the second motor car stops running, the driving assembly on the first motor car starts running and drives the first motor car to move along the first sliding rail, and the first motor car pulls the second motor car to move reversely through the adjusting cross rod.
