Detailed Description

The invention will be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and only schematically illustrate the basic structure of the invention, and the direction of the present embodiment is based on the direction of fig. 1.

As shown in fig. 1 and 2, a special lifting appliance for mounting a prefabricated outer wall comprises a lifting frame 1, a lifting hook 2 and a lifting chain 3, wherein the lifting frame 1 comprises a lower end cross rod 11, a lower end fixing rod piece 12, a vertical rod piece 13, a floor fixing cross rod 14 and an upper end fixing rod piece 15, the vertical rod piece 13 is vertically connected to the lower end cross rod 11, one end of the lower end fixing rod piece 12 is mounted at the joint of the lower end cross rod 11 and the vertical rod piece 13, one end of the upper end fixing rod piece 15 is connected with the vertical rod piece 13, the other end of the upper end fixing rod piece 15 is connected with the other end of the lower end fixing rod piece 12, the floor fixing cross rod 14 is mounted at the joint of the upper end fixing rod piece 15 and the lower end fixing rod piece 12, one end of the lifting chain 3 is connected with the lower end cross rod 11, and the other end of the lifting chain 3 is connected with the lifting hook 2. The lifting hooks 2 and the lifting chains 3 are respectively provided with two lifting hooks 2, each lifting hook 2 is connected with one lifting chain 3, and the length of the joint of the two lifting chains 3 and the lower end cross rod 11 is equal to that of the end close to the lower end cross rod 11.

The upper end fixing rod 15 is perpendicular to the lower end fixing rod 12, and the length of the upper end fixing rod 15 is equal to that of the lower end fixing rod 12. The lower end fixing rod piece 12 and the vertical rod piece 13 form a 45-degree included angle, and the upper end fixing rod piece 15 and the vertical rod piece 13 form a 45-degree included angle. The upper end fixed rod piece 15, the lower end fixed rod piece 12 and the vertical rod piece 13 form an equilateral right-angled triangle, so that the structure is firm, and the stress balance can be ensured.

The vertical rod 13 is vertically connected to the middle point of the lower end cross rod 11, the middle point of the floor fixing cross rod 14 is connected with the connection part of the upper end fixing rod piece 15 and the lower end fixing rod piece 12, and the floor fixing cross rod 14 is parallel to the lower end cross rod 11. This ensures that the hanger 1 is balanced in terms of force.

Two sides of the vertical rod 13 are connected with a lower end fixing support 16, one end of the lower end fixing support 16 is connected with the vertical rod 13, and the other end of the lower end fixing support 16 is connected with the lower end cross rod 11.

One end of the vertical rod piece 13 is provided with a tower crane chain-hanging bolt 17.
