[0023] like Figure 1-Figure 3 As shown, an embodiment of the utility model provides a hood-type annealing furnace gas pipeline interface adjustment device. The adjustment device includes a frame body 1 and an adjustment leg 2. The frame body 1 is used to be covered on the furnace body 9. The adjustment leg 2 is horizontally arranged on the outer wall of the frame body 1 and extends toward the outside of the frame body 1. A circular hole 21 with a vertical center line is provided on the adjustment leg 2, and the circular hole 21 is coaxial with the furnace gas pipeline interface 91 during normal use. The height of the adjustment leg 2 is the height of the furnace gas pipeline interface 91 during normal use. The furnace gas pipeline interface 91 during normal use means that the furnace gas pipeline interface 91 is not tilted or deformed.
[0024] When the stove gas pipe interface 91 tilts and deforms, place the frame body 1 over the stove body 9 and adjust the angle of the frame body 1 so that the adjustment leg 2 is aligned with the orientation of the stove gas pipe interface 91. Next, adjust the frame body 1 to maintain a horizontal position. Since the adjustment leg 2 is positioned horizontally on the frame body 1, when the frame body 1 is horizontal, the adjustment leg 2 is also horizontal. After adjusting the position of the frame body 1, use the circular hole 21 as a reference to adjust the stove gas pipe interface 91 so that it is coaxial with the circular hole 21, thereby restoring the horizontal position of the stove gas pipe interface 91. Depending on the actual situation, an offset of less than 1 mm is allowed between the centerline of the stove gas pipe interface 91 and the centerline of the circular hole 21. Using the lower surface of the adjustment leg 2 as a reference, measure the distance between the lower surface of the adjustment leg 2 and the upper surface of the flange of the stove gas pipe interface 91 every 90°. Based on the four sets of measured data, the amount of tilt and deformation of the stove gas pipe interface 91 can be analyzed and determined. Then, based on the measured data, repair the furnace platform gas pipe interface 91 so that the lower surface of the adjustment leg 2 is parallel to the upper surface of the flange of the furnace platform gas pipe interface 91, thereby restoring the flatness of the furnace platform gas pipe interface 91. Depending on the actual situation, a deviation of less than 1 mm is allowed between the parallelism of the lower surface of the adjustment leg 2 and the upper surface of the flange of the furnace platform gas pipe interface 91. Using the height of the lower surface of the adjustment leg 2 as a reference, adjust the height of the furnace platform gas pipe interface 91 so that the upper surface of the flange of the furnace platform gas pipe interface 91 is flush with the lower surface of the adjustment leg 2, thereby restoring the vertical height of the furnace platform gas pipe interface 91. Depending on the actual situation, a distance error of less than 10 mm is allowed between the upper surface of the flange of the furnace platform gas pipe interface 91 and the lower surface of the adjustment leg 2. After the furnace platform gas pipe interface 91 is repaired, hoist the heating cover onto the furnace platform. Using the repaired furnace platform gas pipe interface 91 as a reference, the heating cover gas pipe interface can be repaired in the same manner. In summary, it is simpler and more convenient to adjust the stove gas pipeline interface 91 and the heating cover gas pipeline interface by using the adjustment device, which saves time.
[0025] Furthermore, the adjustment leg 2 is detachably connected to the frame body 1. Optionally, the adjustment leg 2 is connected to the frame body 1 via bolts. After adjusting the gas pipe interface 91 of the furnace table and the gas pipe interface of the heating cover, the adjustment leg 2 can be removed from the frame body 1, reducing the space occupied by the adjustment device and facilitating storage.
[0026] Furthermore, the adjustment device includes guide posts 3 vertically disposed on either side of the hearth body 9 and a plurality of guide legs 4 spaced apart along the circumference of the frame body 1. The guide legs 4 are horizontally fixed to the outer sidewall of the frame body 1 and extend outward from the frame body 1. A guide ring 41 is disposed on one end of the guide post 3 away from the frame body 1. The guide ring 41 is configured to fit over the guide post 3.
[0027] Before the frame body 1 is placed on the furnace main body 9, the guide ring 41 is first placed on the guide column 3, so that the frame body 1 is placed on the furnace main body 9 along the length direction of the guide column 3. The guide column 3 and the guide leg 4 play a positioning role, which makes it more convenient to place the frame body 1 on the furnace main body 9.
[0028] Furthermore, the guide leg 4 is detachably connected to the frame body 1. Optionally, the guide leg 4 is connected to the frame body 1 by bolts. After the adjustment of the furnace base gas pipeline interface 91 and the heating cover gas pipeline interface is completed, the guide leg 4 can be removed from the frame body 1, reducing the space occupied by the adjustment device and facilitating storage.
[0029] Furthermore, the guide ring 41 includes a fixed plate 411 and a rotating arc plate 412. The fixed plate 411 is fixedly mounted on the end of the guide leg 4 away from the frame body 1. The rotating arc plate 412 is rotatably mounted on the fixed plate 411 and, together with the fixed plate 411, forms an annular space that can be mounted on the guide column 3. One end of the rotating arc plate 412 is rotatably connected to the fixed plate 411 via a pin 413, and the other end of the rotating arc plate 412 is detachably connected to the fixed plate 411.
[0030] To fit the guide ring 41 onto the guide post 3, the end of the rotating arc plate 412 away from the pin 413 is first removed from the fixed plate 411. The rotating arc plate 412 is then rotated about the pin 413 to open the annular space. The guide post 3 is then positioned within the annular space, and the rotating arc plate 412 is rotated to reattach the end away from the pin 413 to the fixed plate 411, thereby sealing the guide post 3 within the annular space and allowing the guide ring 41 to be fitted onto the guide post 3. The guide ring 41 has a simple overall structure and is easy to operate.
[0031] Optionally, the fixed plate 411 is L-shaped overall, with one end of the fixed plate 411 fixed to the guide leg 4 and the other end of the fixed plate 411 extending toward the end away from the guide leg 4. A rotating arc plate 412 is rotatably mounted on the end of the fixed plate 411 away from the guide leg 4. The other end of the rotating arc plate 412 is detachably connected to the end of the fixed plate 411 fixed to the guide leg 4 via bolts. The L-shape of the fixed plate 411 facilitates the formation of an annular space. The detachable connection between the rotating arc plate 412 and the fixed plate 411 using bolts further facilitates operation.
[0032] Furthermore, the adjustment device also includes a plurality of leveling legs 5 vertically arranged around the furnace main body 9 and a plurality of short legs 6 spaced apart along the circumference of the frame main body 1. The short legs 6 are horizontally fixed on the outer side wall of the frame main body 1 and extend toward the outside of the frame main body 1. The leveling legs 5 correspond one-to-one with the short legs 6, that is, when the frame main body 1 is covered on the furnace main body 9, each short leg 6 is above the corresponding leveling leg 5. By measuring the distance between the lower surface of each short leg 6 and the upper surface of the leveling leg 5, it can be determined whether the frame main body 1 is level as a whole. And the frame main body 1 can be leveled based on the measurement data. Using the short legs 6 and the leveling legs 5 as a reference makes it more convenient to level the frame main body 1.
[0033] Furthermore, the short legs 6 are detachably connected to the frame body 1. Optionally, the short legs 6 are connected to the frame body 1 via bolts. After the gas pipe interface 91 of the furnace table and the gas pipe interface of the heating hood are adjusted, the short legs 6 can be removed from the frame body 1, reducing the space occupied by the adjustment device and facilitating storage.
[0034] Furthermore, a limit rod 11 is provided inside the frame body 1 to secure the frame body 1 to the stove body 9. Optionally, the frame body 1 is a rectangular parallelepiped, with the limit rod 11 and the frame body 1 forming an octagon. When the frame body 1 is placed over the stove body 9, the limit rod 11 abuts against the sidewall of the stove body 9, further stabilizing the placement of the frame body 1.
[0035] Furthermore, the frame body 1 is provided with a scale line 7. When the frame body 1 is placed on the stove body 9, if the scale line 7 coincides with the center line of the stove body 9, it means that the frame body 1 is placed in place. Otherwise, the frame body 1 needs to be adjusted.
[0036] Furthermore, a plurality of lifting rings 8 are provided on the side walls of the frame body 1, and the plurality of lifting rings 8 are evenly spaced around the circumference of the frame body 1. By providing the lifting rings 8, when the frame body 1 needs to be placed on the furnace table body 9, a lifting device can be connected to the lifting rings 8 for lifting, saving time and effort.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
