The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] Reference Figure 1 and Figure 2 As shown, the utility model provides a lifting bracket for a glass fiber board, comprising: a lifting bracket body 1, a sealing cylinder 2, a suction cup 3, and a piston assembly 4.

[0027] In this embodiment, the hanger body 1 includes a longitudinal rod 11 and a transverse rod 12 .

[0028] There are two longitudinal rods 11. The two longitudinal rods 11 are arranged opposite to each other. There are multiple transverse rods 12. The transverse rod 12 is connected between the two longitudinal rods 11. The multiple transverse rods 12 are arranged at intervals along the length direction of the longitudinal rods 11. The sealing cylinder 2 is arranged at the intersection of the transverse rod 12 and the longitudinal rod 11.

[0029] There are multiple sealing cylinders. The sealing cylinder 2 is cylindrical.

[0030] In this embodiment, see Figure 1 As shown, the number of sealing cylinders is six. The sealing cylinder 2 is installed on the hanger body 1. The sealing cylinder 2 is arranged vertically.

[0031] The suction cup 3 is connected to the bottom of the sealing cylinder 2. The bottom of the cylinder is provided with an air hole connected to the suction cup 3. The top of the cylinder is provided with a pressure relief hole. In this embodiment, the air hole and the pressure relief hole are respectively arranged on the end surface of the sealing cylinder.

[0034] An elastic expansion membrane 43 is connected between the outer edges of the upper piston plate 41 and the lower piston plate 42. A sealed cavity is formed between the elastic expansion membrane 43 and the upper piston plate 41 and the lower piston plate 42. The elastic expansion membrane is a rubber membrane.

The driving member 5 is installed on the upper part of the sealing cylinder 2. The inner side of the cylinder wall of the sealing cylinder 2 is installed with a limiting member 21. The limiting member 21 is arranged above the upper piston plate 41.

[0036] The driving member 5 drives the lower piston plate 42 to rise so that the air inside the suction cup 3 is sucked into the sealing tube 2 through the air hole, so that the air pressure inside the suction cup 3 is reduced. After the upper piston plate 41 is pressed against the stopper 21, the sealing cavity is squeezed, so that the elastic expansion membrane 43 is pressed against the inner side of the side wall of the sealing tube 2.

[0037] When the fiberglass board lifting frame of the utility model is used to lift the fiberglass board, it is connected to the hanger body through the lifting rope of the lifting machine. The hanger body is lowered so that the multiple suction cups on the hanger body are pressed against the upper surface of the fiberglass board. A sealed environment is formed between the suction cup and the upper surface of the fiberglass board. The driving member lifts the lower piston plate upward so that the air inside the suction cup is sucked into the sealing cylinder through the air hole, so that the air pressure inside the suction cup is reduced, and the suction cup is firmly adsorbed on the fiberglass board. The driving member continues to lift the lower piston plate upward so that the upper piston plate is pressed against the limit member, so that the sealing cavity is squeezed, and the elastic expansion membrane is pressed against the inner side of the side wall of the sealing cylinder to improve the sealing between the piston assembly and the inner wall of the side wall of the sealing cylinder.

[0038] When the suction cup needs to be separated from the glass fiber board, the driving member pushes down the piston plate to restore the air pressure in the suction cup.

[0039] As a preferred embodiment, the upper piston plate 41 is provided with a through hole. The driving member 5 is an electric hydraulic push rod. The electric hydraulic push rod is arranged along the axial direction of the sealing cylinder 2. The electric hydraulic push rod has a fixed end and a telescopic end. The fixed end of the electric hydraulic push rod is installed on the top of the sealing cylinder 2. The telescopic end of the electric hydraulic push rod can be movably inserted into the through hole and connected to the lower piston plate 42. A sealing member is installed between the hole wall of the through hole and the outer wall of the telescopic end of the electric hydraulic push rod.

[0040] See also Figure 2 As shown, the position-limiting member 21 is installed in the sealing cylinder 2 in an adjustable manner.

[0041] In this embodiment, the limiting member 21 is a ring plate, and the outer diameter of the ring plate is adapted to the inner diameter of the sealing tube 2 .

[0042] A threaded hole is provided on the top of the cylinder, in which a screw rod 22 is screwed. The end of the screw rod 22 is rotatably mounted on the ring plate.
