Description

Technical Field

[0001] This utility model relates to the field of electric heating wire technology, specifically to a large furnace body electric heating wire installation device. Background Technology

[0002] In the heating system of large industrial furnaces (such as heat treatment furnaces, metallurgical furnaces, chemical reaction furnaces, etc.), the installation accuracy and layout rationality of electric heating wires directly determine the heating uniformity and process stability of the furnace body.

[0003] Currently, the installation of electric heating wires in traditional large furnaces mostly relies on manual assembly in sections. Manual assembly in sections is inefficient, has low precision and safety. For electric heating wires with multiple coils, manual installation in sections requires a lot of manpower and time, and it is difficult to ensure the uniformity of the electric heating wires. This can easily lead to an imbalance in the temperature field distribution inside the furnace, which in turn affects the heat treatment of workpieces, material reactions and other process effects. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a fixed base, on the upper surface of which are provided two fixed frames. Each of the two fixed frames has a through hole. A central roller is provided on the inner surface of each of the two through holes. Two limiting rings are provided on the outer surface of the central roller. Two fixing rings and two positioning rings are provided on the outer surface of the central roller. Four fixing seats 2 are provided on the two positioning rings. Four fixing seats 1 are provided on the two fixed rings. Each of the four fixing seats 1 is provided with a support rod 1. Each of the four fixing seats 2 is provided with a support rod 2. The other ends of the four support rods 1 and 2 are rotatably connected to support columns. Two mounting plates are provided on the four support columns. Each of the two mounting plates has a fixing hole.

[0006] Preferably, the two fixing frames are symmetrically designed, and both ends of the central roller shaft are located on the inner surface of the through hole.

[0007] Preferably, both limiting rings are fixedly connected to the central roller shaft, and both fixing rings are rotatably connected to the central roller shaft.

[0008] Preferably, all eight fixed seats are located on the outer surface of the two fixed rings, and all eight support rods are rotatably connected to the fixed seats.

[0009] Preferably, the two positioning rings are threadedly connected to the central roller shaft, and the eight fixing seats are all located on the outer surface of the two positioning rings.

[0010] Preferably, all eight fixed seats are rotatably connected to the support rod, and the two mounting plates are symmetrically designed.

[0011] Preferably, a motor is fixedly connected to the outer surface of one of the fixed frames, and the central roller is driven by the motor.

[0012] Compared with the prior art, this utility model provides a large furnace body electric heating wire installation device, which has the following beneficial effects: 1. The electric heating wire can be spread more evenly by the motor driving the central roller shaft and the support column.

[0013] 2. The assembly of electric heating wires by using a motor to drive the central roller shaft and the linkage between the fixed ring and the positioning ring is more accurate and safer than manual installation. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 3 - Figure 4This embodiment of a large furnace body electric heating wire installation device includes a fixed base 1. Two fixing brackets 2 are provided on the upper surface of the fixed base 1. Each fixing bracket 2 has a through hole 13. A central roller 3 is provided on the inner surface of the two through holes 13. Two limiting rings 10 are provided on the outer surface of the central roller 3. Two fixing rings 9 are provided on the outer surface of the central roller 3. Two positioning rings 12 are provided on the outer surface of the central roller 3. Four fixing seats 15 are provided on the two positioning rings 12. Four fixing seats 14 are provided on the two fixing rings 9. Each of the four fixing seats 14 has a support rod 8. Each of the four fixing seats 15 has a support rod 7. The other end of rod 1 (8) and support rod 2 (7) is rotatably connected to support column 6. Two mounting plates 5 are set on the four support columns 6. Each mounting plate 5 is provided with a fixing hole 4. The operator inserts the electric heating wire into the support column 6 and starts the motor. Then the motor 11 drives the central roller shaft 3 to rotate (the threads at both ends of the central roller shaft 3 are in opposite directions). The central roller shaft 3 drives the positioning rings 12 on both sides to move towards the fixing ring 9. The fixing ring 9 drives the fixing seat 2 (15) to control support rod 2 (7). The distance between the fixing ring 9 and the positioning ring 12 is shortened, and the direction of support rod 1 (8) is offset. Support rod 1 (8) and support rod 2 (7) are offset at the same time to support the support column 6. Then the support column 6 opens the electric heating wire to the appropriate size.

[0018] Please see Figure 1 - Figure 2 The two fixed frames 2 are symmetrically designed. Both ends of the central roller shaft 3 are located on the inner surface of the through hole 13. The two limiting rings 10 are fixedly connected to the central roller shaft 3. The two fixed rings 9 are rotatably connected to the central roller shaft 3. The eight fixed seats 14 are located on the outer surface of the two fixed rings 9. The eight support rods 8 are rotatably connected to the fixed seats 14. The two positioning rings 12 are threadedly connected to the central roller shaft 3. The eight fixed seats 15 are located on the outer surface of the two positioning rings 12. The eight fixed seats 15 are rotatably connected to the support rods 7. The two mounting plates 5 are symmetrically designed. The outer surface of one of the fixed frames 2 is fixedly connected to a motor 11. The central roller shaft 3 is driven by the motor 11. The operator places the fixing plate in the fixing hole 4 on the mounting plate. Finally, the operator uses the buckle on the fixing plate to lock the electric heating wire to complete the installation of the electric heating wire. Finally, the operator unloads the assembled electric heating wire and starts the motor 11 to reverse and reset the positioning ring.

[0019] The working principle of the above embodiment is as follows: The operator inserts the electric heating wire into the support column 6, starts the motor, and then the motor 11 drives the central roller shaft 3 to rotate (the threads at both ends of the central roller shaft 3 are in opposite directions). The central roller shaft 3 drives the two positioning rings 12 to move towards the fixed ring 9. The fixed ring 9 drives the fixed seat 15 to control the support rod 7. The distance between the fixed ring 9 and the positioning ring 12 is shortened, and the support rod 8 is offset. The support rod 8 and the support rod 7 are offset at the same time to support the support column 6. Then the support column 6 opens the electric heating wire to the appropriate size. Then the operator places the fixing plate into the fixing hole 4 on the mounting plate. Then the operator uses the buckle on the fixing plate to lock the electric heating wire to complete the installation of the electric heating wire. Finally, the operator unloads the assembled electric heating wire and starts the motor 11 to reverse and reset the positioning ring.
