[0002] Heat treatment is an extremely important process in the production of mechanical and electronic industries. The main heating equipment used in this process is the heat treatment furnace. The mechanical properties of the metal materials in the furnace are changed by heating the heat treatment furnace. Because the properties of the internal organization of metal materials are different at different temperatures, the desired organizational structure can be obtained by heat treating the metal materials, thereby obtaining the better mechanical properties that people need.

[0003] When assembling the heat treatment furnace, the shells of the heat treatment furnace need to be hoisted and stacked together in sequence for transportation and splicing, and then the furnace body is welded. However, the efficiency is very low when the furnace body is stacked multiple times, and multiple shells cannot be spliced and docked at one time.

[0032] Please refer to Figure 1-10 , the present invention provides a technical solution: a spliced and assembled large-scale heat treatment furnace, including a plurality of housings 1 and a base 2. Limiting members 8 are fixedly connected to each of the plurality of housings 1, and two assembling groups are arranged on the base 2;

[0033] The assembling group includes a support block 3 and a limit groove 4. The support block 3 is slidably connected inside the limit groove 4. The support block 3 is rotatably connected to a frame plate 5. The frame plate 5 is fixedly connected to a hook 30. Two chains 13 are arranged on both the front and rear sides of the frame plate 5. A plurality of driving blocks 6 are arranged above the frame plate 5. Each of the plurality of driving blocks 6 is rotatably connected to a support plate 7. The support plate 7 is slidably connected to the limiting member 8. Extension edges 9 are fixedly connected to both the front and rear side walls of the support plate 7. Rack bars 10 are arranged below the extension edges 9. The rack bars 10 are all arc-shaped. The rack bars 10 are all slidably connected to the frame plate 5. The rack bars 10 are all engaged with first gears 11. The first gears 11 are all rotatably connected to the side wall of the frame plate 5. The rotating shafts of the first gears 11 are all fixedly connected to sprockets 12. The two chains 13 are respectively in transmission connection with three sprockets 12 on the front and rear sides of the frame plate 5. The two sprockets 12 located on the rightmost side are both fixedly connected to second gears 14. The two second gears 14 are both engaged with a tooth ring 15. The two tooth rings 15 are both fixedly connected to the support block 3;

[0034] A driving assembly is arranged on one side of each of the two assembling groups. The driving assembly is used to drive the housings 1 on the two assembling groups to be butted against each other.

[0035] When the above - mentioned solution is put into actual use, first, several shells 1 are respectively hoisted onto several support plates 7, so that the limit pieces 8 are located outside the support plates 7. Then, a crane or a hoist uses the two hooks 30 on the sides of the two support plates 5 to lift the ends of the two support plates 5. When the two support plates 5 are lifted, the ends close to the base 2 will rotate around the rotating shaft. When the support plates 5 rotate, they will drive several first gears 11 and second gears 14 to rotate. When the second gear 14 rotates, it will mesh with and rotate along the toothed ring 15. When the second gear 14 rotates, it will drive the sprocket 12 to rotate. And when one sprocket 12 rotates, it will drive multiple sprockets 12 to rotate simultaneously through the chain 13. When the sprocket 12 rotates, it will mesh with the rack bar 10 and drive the rack bar 10 to slide along the support plate 5. When the rack bar 10 slides, it will jack up the support plate 7 from below the extension edge 9. Thus, when the support plate 5 rotates around the rotating shaft of the support block 3, the support plate 7 rotates around the rotating shaft of the drive block 6. Therefore, when the support plate 7 rotates, the shell 1 maintains a vertical position. When the crane hoists the two support plates 5 to a position perpendicular to the base 2, several shells 1 are also in a vertical position and are vertically arranged layer by layer. Then, through the drive assembly, the two support blocks 3 drive the two support plates 5 to slide along the limit groove 4 and approach each other. Furthermore, the side walls of the shells 1 above the two support plates 5 approach each other (during this process, the crane or hoist also needs to move along with the support plate 5). When the drive assembly drives the support plates 5 to approach each other to the extreme position, the side walls of the two groups of vertically arranged and layered shells 1 also approach each other. Then, the drive assembly lowers several shells 1, so that the lowermost shell falls on the support part (the support part is a circular support platform, not shown in the figure) at the middle position of the top of the base 2, and the upper shells stack on top of the lower shell 1 while their side walls approach each other. Thus, several shells 1 are spliced into a complete furnace body, and then welding can be carried out;

[0036] During welding, through the assembly group, multiple shells 1 can be directly assembled into the shape of a furnace body, which facilitates the assembly of the entire furnace body. When welding the shell 1, the crane or hoist continues to hold the hook 30. At this time, several shells 1 maintain the shape of the furnace body and are in contact with each other. Workers can weld the shells 1 on different layers simultaneously, thereby improving the welding efficiency and progress;

[0037] During actual use, the limit piece 8 is located above the bottom of the shell 1. When multiple shells 1 are stacked together, the joint between the two shells 1 is exposed to the outside, which facilitates welding;

[0038] After welding is completed, the two support plates 5 are hoisted to both sides so that the two support plates 5 can be separated and reset, and then the welded furnace body can be taken out.

[0039] As a further solution of the present invention, the driving assembly includes two first hydraulic rods 16 and several second hydraulic rods 17. Both of the two first hydraulic rods 16 are fixedly connected to the base 2, and the output ends of both of the two first hydraulic rods 16 are fixedly connected to the support block 3. Several of the second hydraulic rods 17 are fixedly connected between the driving block 6 and the inner wall of the frame plate 5, and the driving blocks 6 are all slidably connected to the frame plate 5.

[0040] When the above driving assembly is working, when the two frame plates 5 are perpendicular to the base 2, control the first hydraulic rod 16 to extend, so that the first hydraulic rod 16 pushes the support block 3 to move to the limit position in the middle of the base 2, and then the two groups of shells 1 are attached, and then the second hydraulic rod 17 shortens (it is not necessary to shorten to the limit position), so that several shells 1 are stacked on top of each other;

[0041] After the furnace body is welded, control the second hydraulic rod 17 to shorten to a certain extent again. At this time, the driving block 6 will drive the support plate 7 to descend, so that the support plate 7 is separated from the limiting member 8, and then the two frame plates 5 are reset, and the first hydraulic rod 16 is reset, and then the furnace body is taken out.

[0042] As a further solution of the present invention, two fixing plates 18 are fixedly connected to each of the driving blocks 6, a contact block 19 is fixedly connected to each of the fixing plates 18, a push rod 20 is arranged on the right side of each of the contact blocks 19, the right side of the contact block 19 is an inclined surface and the top is arc-shaped, the push rods 20 are all slidably connected to the extension edge 9, the contact block 19 can push the push rod 20 to move, an adjusting rod 21 is arranged on the right side of each of the push rods 20, the adjusting rod 21 is arc-shaped, and the adjusting rods 21 on the right side of the push rods 20 are all slidably connected to the support plate 7 on the right side of the push rod 20; A spring 22 for its reset is fixedly connected to each of the adjusting rods 21.

[0043] As a further solution of the present invention, the support block 3 is T-shaped.

[0044] As a further solution of the present invention, several rollers 23 are rotatably connected to the driving block 6.

[0045] As a further solution of the present invention, a contact wheel 24 is rotatably connected to each of the push rods 20.

[0046] When the above solution is put into actual use, the T-shaped support block 3 is convenient to be pushed by the first hydraulic rod 16. Moreover, the left side of the top of the support block 3 is trapezoidal, which is convenient for supporting the frame plate 5;

[0047] When the shelf board 5 rotates around the rotating shaft, the first gear 11 will drive the rack bar 10 to jack up the support plate 7 and the extension edge 9, causing the support plate 7 to rotate around the rotating shaft. When the support plate 7 rotates around the rotating shaft, it will drive the push rod 20 to rotate. When the push rod 20 rotates, its end will contact the contact block 19, and the inclined surface of the contact block 19 will gradually push the push rod 20 to slide along the extension edge 9 when the push rod 20 rotates. When the push rod 20 slides, it will push the tab on the side of the adjusting rod 21, enabling the push rod 20 to smoothly push the adjusting rod 21 to slide inside the support plate 7. Since the support plate 7 is located inside the limiting member 8 when the housing 1 is placed on the support plate 7, but for the convenience of placing the housing 1, the limiting member 8 is longer than the support plate 7, which causes the front and rear ends of the side wall of the housing 1 to have a certain inclination when placed. If adjustment cannot be made, it will affect the fitting efficiency of the two groups of housings 1. Therefore, when the push rod 20 pushes the adjusting rod 21 to slide along the support plate 7, the two adjusting rods 21 will move from two directions inside the limiting member 8 respectively, and the moving distances of the two adjusting rods 21 are fixed. So when the two adjusting rods 21 move to the limit distance, they will adjust the two ends of the limiting member 8, making the side wall of the housing 1 horizontal, thus facilitating subsequent alignment. The spring 22 can facilitate the reset of the adjusting rod 21;

[0048] The roller 23 can reduce friction when the second hydraulic rod 17 drives the driving block 6 to move, while the contact wheel 24 can reduce the friction between the push rod 20 and the contact block 19.

[0049] As a further solution of the present invention, support rods 25 are rotatably connected to the bottom of the shelf board 5, limit blocks 26 are rotatably connected to the bottom ends of the support rods 25, the limit blocks 26 are slidably connected inside the limit grooves 4, the base 2 is fixedly connected with a cylinder 27, the cylinder 27 is fixedly connected with an insertion plate 28, protrusions 29 are arranged on the left and right sides of the insertion plate 28, and the protrusions 29 are fixedly connected with the base 2.

[0050] When the above solution works, when the hook 30 is lifted and the shelf board 5 rotates around the rotating shaft, the shelf board 5 will drive the right end of the support rod 25 to move, and the support rod 25 will pull the limit block 26 to slide along the limit groove 4. When the shelf board 5 is in a vertical state, the cylinder 27 is started, and the cylinder 27 will push the insertion plate 28 to move to a position where it fits with the protrusion 29. At this time, the right side wall of the insertion plate 28 will fit with the left side wall of the limit block 26, thereby playing an auxiliary supporting role for the shelf board 5. When the welding is completed, the cylinder 27 also needs to be reset first.

[0051] As a further solution of the present invention, balls are rotatably connected to the top ends of the support plates 7.

[0052] When the above solution is in operation, the friction between the support plate 7 and the housing 1 can be reduced by the ball bearings (the ball bearings are prior art and will not be described or shown in detail).

[0053] Working principle: First, a number of housings 1 are respectively hoisted onto a number of support plates 7, such that the limiting members 8 are located outside the support plates 7. Then, a crane or a hoist uses the two hooks 30 on the sides of the two support plates 5 to lift the ends of the two support plates 5. When the two support plates 5 are lifted, the ends close to the base 2 will rotate around the rotating shaft. When the support plates 5 rotate, they will drive a number of first gears 11 and second gears 14 to rotate. When the second gears 14 rotate, they will mesh with and rotate along the toothed ring 15. When the second gears 14 rotate, they will drive the sprockets 12 to rotate. And when one sprocket 12 rotates, it will drive multiple sprockets 12 to rotate simultaneously through the chain 13. When the sprockets 12 rotate, they will mesh with the rack bar 10 and drive the rack bar 10 to slide along the support plate 5. When the rack bar 10 slides, it will lift the support plate 7 from below the extension edge 9. Thus, when the support plate 5 rotates around the rotating shaft of the support block 3, the support plate 7 rotates around the rotating shaft of the drive block 6. Consequently, when the support plate 7 rotates, the housing 1 maintains a vertical position. When the crane hoists the two support plates 5 to a position perpendicular to the base 2, the several housings 1 are also in a vertical position and are vertically arranged layer by layer. Then, through the drive assembly, the two support blocks 3 drive the two support plates 5 to slide along the limiting grooves 4 and approach each other. Furthermore, the side walls of the housings 1 above the two support plates 5 approach each other (during this process, the crane or hoist also needs to move along with the support plate 5). When the drive assembly drives the support plates 5 to approach each other to the limit position, the side walls of the two groups of vertically arranged layer by layer housings 1 also approach each other. Then, the drive assembly further lowers the several housings 1, such that the lowermost housing falls onto the support portion (the support portion is a circular support platform, not shown in the figure) at the middle position on the top of the base 2, while the upper housings stack on top of the lower housing 1 while their side walls approach each other. Thus, the several housings 1 are assembled into a complete furnace body, and then welding can be carried out;

[0054] During welding, through the assembly group, multiple housings 1 can be directly assembled into the shape of a furnace body, facilitating the assembly of the entire furnace body. When welding the housing 1, the crane or hoist continues to hold the hook 30. At this time, the several housings 1 maintain the shape of the furnace body and are mutually adhered together. Workers can simultaneously weld the housings 1 at different layers, thereby improving the welding efficiency and progress;

[0055] During actual use, the limiting member 8 is located above the bottom of the housing 1. When multiple housings 1 are stacked together, the joint between two housings 1 is exposed to the outside, facilitating welding;

[0056] After welding is completed, lift the two frame plates 5 to both sides so that the two frame plates 5 can be separated and reset, and then take out the welded furnace body.
