It adopts an all-steel and all-electric structure, composed of several sections, and is divided into several zones longitudinally according to the annealing curve. Different heating and cooling systems are used in each zone according to the temperature of the glass plate and the requirements of the annealing process, so as to achieve good annealing and reasonable cooling.

[0003] For example, the publication number CN101077820A disclosed a float glass annealing furnace air cooling device on November 28, 2007, which is characterized in that two fans 3 and 18 are arranged on the top of the annealing furnace, and an air duct 12 is connected between them. Three gate valves 13a, 13, and 13b are arranged on the air duct 12. The gate valves 13a and 13 are connected to the upper main air duct 17, and the other end is connected to the secondary collection pipe 16. The primary collection pipe 8 drawn out from the annealing furnace is respectively connected to the secondary collection pipe 16. The gate valves 13 and 13b are connected to the lower main air duct 4, which is connected to the horizontal distribution pipe 9 at the bottom of the annealing furnace 5. After the air duct disclosed above is installed, the air duct expands due to heat, which makes the air duct easy to fall off after installation, and the air duct installation is unstable. Summary of the invention

[0004] The purpose of the utility model is to provide a glass annealing furnace air duct installation device that stably supports the air duct. The utility model realizes stable support for the air duct that expands due to heat by rotating the roller on the connecting seat, and quickly eliminates the thermal expansion movement of the air duct by rolling, so that the expansion stress of the air duct can be released, and the air duct is safer and more reliable.

[0005] To achieve the above purpose, the technical solution adopted by the utility model to solve its technical problem is: a glass annealing furnace air duct installation device includes a hanger, a roller in contact with the air duct is arranged between the hangers, a connecting seat is provided on the hanger, and the roller sleeve is arranged on the connecting seat.

[0006] As a further solution of the utility model, a rotating shaft is provided on the rotating roller, and a fixing pin is provided on the rotating shaft.

[0007] As a further solution of the utility model, the cross section of the suspension rod is circular, and the cross section of the rotating roller is circular.

[0008] As a further solution of the utility model, a mounting block is provided on the suspension rod, and a connecting bolt is provided on the mounting block.

[0009] As a further solution of the utility model, the mounting block is provided with a first through hole for the connecting bolt to pass through.

[0010] As a further solution of the utility model, a clamping block is provided on the suspension rod, and a clamping groove cooperating with the clamping block is provided on the mounting block.

[0011] As a further solution of the utility model, the mounting block is provided with an adjusting bolt, the mounting block is provided with a threaded hole for the adjusting bolt to pass through, and the clamping block is provided with a second through hole that cooperates with the adjusting bolt.

[0012] The beneficial effects of the utility model are:

[0013] The air duct is placed on the roller. When the air duct expands due to temperature, the roller rotates between the connecting seats on the suspension rod, and then the thermal expansion movement of the air duct is quickly eliminated by the rolling of the roller, so that the expansion stress of the air duct can be released, thereby ensuring that the air duct is fixed more safely and reliably;

[0014] The hanger is installed through a mounting block and connecting bolts, and the block at the end of the hanger matches the slot on the mounting block. The position of the moving block in the slot of the mounting block makes it easy to adjust the position of the hanger and the roller, thereby adapting to the support work of different numbers of air ducts.

Specifically, the hanger 1 is installed on the upper part of the annealing furnace, there are two hangers 1, and the roller 2 is set between the two hangers 1.

[0022] When in use, the air duct is placed on the roller 2 for support work. When the air duct expands due to temperature, the roller 2 rotates between the connecting seats 3 on the suspension rod 1, and then the thermal expansion movement of the air duct is quickly eliminated by the rolling of the roller 2, so that the expansion stress of the air duct can be released, thereby ensuring that the air duct is fixed more safely and reliably.

[0023] Reference Figure 1 A rotating shaft 4 is provided on the rotating roller 2, and the rotating shaft 4 is connected to the connecting seat 3. A fixing pin 5 is provided on the rotating shaft 4.

Specifically, a through groove for the rotating shaft 4 to rotate is provided on the connecting seat 3, and the fixing pin 4 is fixedly connected to the rotating shaft 4.

[0024] The cross section of the suspension rod 1 is circular, and the cross section of the roller 2 is circular, so as to ensure that the contact between the roller 2, the suspension rod 1 and the air duct is linear contact, and the rotation moves in the direction of the expansion of the air duct; the expansion and movement of the air duct caused by the heating of the shell is effectively eliminated, and the fixing method is safer and more convenient.

[0025] The suspension rod 1 is provided with a mounting block 6 , and the mounting block 6 is provided with a connecting bolt 7 . The stable mounting of the suspension rod 1 is achieved through the cooperation between the mounting block 6 and the connecting bolt 7 .

[0026] The mounting block 6 is provided with a first through hole 8 for the connecting bolt 7 to pass through, thereby facilitating the connecting bolt 7 to pass through the first through hole 8 to achieve connection with the mounting block 6 .

[0027] A clamping block 9 is provided on the suspension rod 1, and a clamping slot 10 cooperating with the clamping block 9 is provided on the mounting block 6. The convenient connection between the suspension rod 1 and the mounting block 6 is achieved through the mutual cooperation between the clamping block 9 and the clamping slot 10.

A second through hole 13 cooperating with the adjusting bolt 11 is provided on the clamping block 9. The position of the movable block 9 in the clamping slot 10 of the mounting block 6 is convenient for adjusting the position of the suspension rod 1 and the roller 2, so as to adapt to the support work of different numbers of air ducts, and the adjusting bolt 11 is rotated to the threaded hole 12 so that the end of the adjusting bolt 11 is inserted into the second through hole 13, so as to fix the position of the clamping block 9 in the clamping slot 10, so as to ensure the fixing of the roller 2 after the position adjustment. In this embodiment, the number of the second through holes 13 is three, and the three second through holes 13 are arranged at equal intervals.
