Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, specifically to a furnace door. Background Technology

[0002] In the manufacturing process of power transformers, several key technological steps need to be completed under specific heat treatment environments. These include the drying of insulating components (such as end rings, support bars, and spacers), the curing of pre-impregnated parts, and stress-relief annealing of some metal parts. These processes are typically carried out in large industrial ovens or curing furnaces. The furnace door, as a crucial component connecting the high-temperature environment inside the furnace with the external operating space, directly affects the stability of the heat treatment process, energy efficiency, production safety, and product quality due to its sealing performance, ease of operation, safety, and high-temperature resistance.

[0003] During the drying process of transformer components, the furnace door needs to be sealed to the furnace body. Currently, many furnace doors use manual bolt locking or lever locking mechanisms to seal the doors. Each time the furnace door is opened and closed, the operator needs to tighten or loosen multiple bolts one by one, or forcefully turn the heavy lever. This process is time-consuming and labor-intensive, especially under the production rhythm that requires frequent material loading and unloading, which increases the labor intensity of the operators and reduces production efficiency.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a furnace door to solve the problem that in the process of drying transformer components, it is necessary to seal the furnace door to the furnace body. Currently, many furnace doors use manual bolt locking or lever locking mechanisms to seal the furnace door. Each time the furnace door is opened and closed, the operator needs to tighten or loosen multiple bolts one by one, or forcefully turn a heavy lever. This process is time-consuming and labor-intensive, especially under the production rhythm that requires frequent material loading and unloading, which increases the labor intensity of the operator and reduces the production efficiency.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: a furnace door is provided, comprising: a furnace door body; a first drive assembly, which is telescopically configured and mounted on an installation reference; and an installation assembly, which is mounted on the furnace door body. The telescopic end of the first drive assembly is driven to connect with the installation assembly, so that the installation assembly is moved by the first drive assembly, thereby causing the furnace door body to move closer to the installation reference.

[0007] Furthermore, the mounting assembly includes: a first mounting part and a second mounting part, which are respectively mounted on both sides of the furnace door body; the first drive assembly includes: at least two first drive members, each first drive member being respectively configured in one-to-one correspondence with the first mounting part and the second mounting part, and each first drive member being driven connected to the corresponding first mounting part and the second mounting part.

[0008] Furthermore, the furnace door is movably configured; the mounting components include: a first mounting member, which is mounted on one side of the furnace door body; and a second mounting member, which is mounted on the side of the furnace door body away from the first mounting member; the first mounting member and the second mounting member are respectively provided with a first opening and a second opening, the first opening and the second opening are oriented in the same direction and are in the same direction of movement of the furnace door body toward each of the first driving members, so that when the furnace door body moves toward the mounting reference, the telescopic end of each of the first driving members can enter the corresponding first opening or second opening.

[0009] Furthermore, the distance between the first mounting component and the mounting reference is greater than the distance between the second mounting component and the mounting reference.

[0010] Furthermore, the first drive assembly also includes at least two protrusions, each protrusion corresponding to a first drive member, and each protrusion being installed on the telescopic end of the corresponding first drive member.

[0011] Furthermore, the furnace door also includes a limiting component, which includes a limiting block, which is movably disposed on the first mounting member and / or the second mounting member along the height direction of the furnace door, and the limiting block protrudes from the first mounting member and / or the second mounting member; the limiting block is located between the first opening and / or the second opening and the corresponding protrusion.

[0012] Furthermore, an inclined guide surface is provided on the side of the limiting block away from the protrusion.

[0013] Furthermore, the furnace door also includes: a furnace door moving assembly, which includes: a track extending along the length of the furnace door and located above the furnace door; a connecting plate having a moving space, within which the track is located; a furnace door body rotatably disposed on the side of the connecting plate opposite to the track; a second driving member mounted on the connecting plate, with its telescopic end located within the moving space; and a first traveling wheel in rolling contact with the track, the first traveling wheel being driven by the second driving member to move along the track.

[0014] Furthermore, the furnace door moving assembly also includes: a drive gear, which is drivenly connected to the second drive member; a first driven gear, which is rotatably disposed within the moving space and meshes with the drive gear, and is connected to the first traveling wheel; a second driven gear, which is rotatably disposed within the moving space and is spaced apart along the length of the furnace door body, and meshes with the drive gear; and a second traveling wheel, which is disposed on the side of the second driven gear away from the second drive member.

[0016] Beneficial effects: 1. By linking the first drive component with the installation component, the traditional manual bolt or lever locking method is replaced, which achieves the sealing of the furnace door body, significantly reduces the physical exertion of operators, and improves the opening and closing efficiency.

[0017] 2. Through the matching design of the opening direction and the movement direction, the telescopic end of the first driving component can automatically embed into the corresponding opening when the furnace door body is close to the installation reference, forming a physical interlock, which provides a precise positioning basis for subsequent sealing actions.

[0018] 3. By designing a differentiated distance, when the furnace door body moves, the first mounting component will preferentially pass over the first driving component at the near end and cooperate with the first driving component at the far end, while the second mounting component will cooperate with the first driving component at the near end. This achieves staggered engagement of the first driving components on both sides, reduces the synchronization accuracy requirements, and improves the fault tolerance of the mechanism.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] According to an embodiment of this utility model, a furnace door is provided; please refer to [link / reference]. Figures 1 to 5 It includes: a furnace door body 1; a first drive assembly 2, which is telescopically mounted on an installation reference; and an installation assembly 3, which is mounted on the furnace door body 1. The telescopic end of the first drive assembly 2 is connected to the installation assembly 3 so that the installation assembly 3 can be moved by the first drive assembly 2 so that the furnace door body 1 moves closer to the installation reference.

[0023] By adopting the above technical solution, the telescopic movement of the first drive component 2 directly drives the installation component 3 to move, thereby causing the furnace door body 1 to move towards the installation reference (furnace body sealing surface) and realize the closing action of the furnace door. Through the linkage design of the first drive component 2 and the installation component 3, the traditional manual bolt or lever locking method is replaced, realizing the sealing of the furnace door body 1, significantly reducing the physical exertion of operators and improving the opening and closing efficiency.

[0024] Please refer to Figure 1 and Figure 4The mounting component 3 includes a first mounting part and a second mounting part, which are respectively mounted on both sides of the furnace door body 1; the first drive component 2 includes at least two first drive members 4, each of which is respectively configured to correspond one-to-one with the first mounting part and the second mounting part, and each of the first drive members 4 is respectively driven connected to the corresponding first mounting part and the second mounting part.

[0025] By adopting the above technical solution, by symmetrically setting the first mounting part and the second mounting part on both sides of the furnace door body 1, and correspondingly configuring independent first driving parts 4 to drive the first mounting parts and the second mounting part on both sides respectively; through the symmetrical layout design of multiple first driving parts 4 and the mounting parts on both sides, the furnace door body 1 can bear a balanced driving force during the movement, avoid the skew and jamming caused by unilateral force, and ensure the stability of the linear movement of the furnace door.

[0026] Please refer to Figure 5 The furnace door is movably mounted; the mounting assembly 3 includes: a first mounting member 5, which is mounted on one side of the furnace door body 1; and a second mounting member 6, which is mounted on the side of the furnace door body 1 away from the first mounting member 5; the first mounting member 5 and the second mounting member 6 are respectively provided with a first opening and a second opening, the first opening and the second opening are oriented in the same direction and are in the same direction of movement of the furnace door body 1 toward each of the first driving members 4, so that when the furnace door body 1 moves toward the mounting reference, the telescopic end of each of the first driving members 4 can enter the corresponding first opening or second opening.

[0027] Specifically, the first driving component 4 is a cylinder or a hydraulic rod.

[0028] When it is necessary to seal the furnace door body 1 with the furnace chamber, the furnace door body 1 moves toward the furnace chamber, and the furnace door body 1 drives the first mounting part 5 and the second mounting part 6 to move. The first opening on the first mounting part 5 and the second opening on the second mounting part 6 move along the telescopic ends of the corresponding first driving parts 4 until the telescopic ends of the first driving parts 4 are located in the corresponding first opening and second opening.

[0029] The first mounting component 5 forms the first mounting portion; the second mounting component 6 forms the second mounting portion.

[0030] Preferably, there are two first mounting members 5; there are two second mounting members 6; and the number of first driving members 4 is the same as the number of first mounting members 5 plus the number of second mounting members 6.

[0031] By adopting the above technical solution, the first mounting component 5 and the second mounting component 6 are provided with a first opening and a second opening in the same direction, and the opening direction is consistent with the movement direction of the furnace door body 1 toward the installation reference. Through the matching design of the opening direction and the movement direction, the telescopic end of the first driving component 4 can automatically embed into the corresponding opening when the furnace door body 1 approaches the installation reference, forming a physical interlock, and providing a precise positioning basis for subsequent sealing actions.

[0032] Please refer to Figure 5 The distance between the first mounting member 5 and the mounting reference is greater than the distance between the second mounting member 6 and the mounting reference, so that the first mounting member 5 misses the first first driving member 4 and then cooperates with the second first driving member 4, so that the telescopic end of the second first driving member 4 enters the first opening. Subsequently, because the distance between the second mounting member 6 and the mounting reference is small, the second opening on the second mounting member 6 cooperates with the first driving member 4. It should be noted that in the direction of the furnace door body 1 moving towards the furnace chamber, the first first driving member 4 is approached first, and the second first driving member 4 is approached next.

[0033] By adopting the above technical solution, the distance from the first mounting part 5 to the mounting reference is greater than the distance from the second mounting part 6 to the mounting reference. Through the differentiated distance design, when the furnace door body 1 moves, the first mounting part 5 preferentially passes over the first driving part 4 at the near end and cooperates with the first driving part 4 at the far end, while the second mounting part 6 cooperates with the first driving part 4 at the near end, realizing the staggered engagement of the first driving parts 4 on both sides, reducing the synchronization accuracy requirement and improving the fault tolerance of the mechanism.

[0034] Please refer to Figure 4 The first drive assembly 2 further includes at least two protrusions 7, each protrusion 7 being configured in a one-to-one correspondence with each first drive component 4, and each protrusion 7 being installed on the telescopic end of the corresponding first drive component 4, so as to drive the furnace door body 1 toward the furnace chamber and seal the furnace chamber.

[0035] By adopting the above technical solution, a protrusion 7 is provided at the telescopic end of the first driving member 4. Each protrusion 7 is embedded in the corresponding first opening and second opening to transmit driving force. Through the interlocking structure of each protrusion 7 with the first opening and second opening, the linear thrust of the first driving member 4 is converted into a direct traction force on the first mounting member 5 and the second mounting member 6, ensuring that the furnace door body 1 obtains sufficient positive sealing pressure and improving sealing reliability.

[0036] Please refer to Figure 2The furnace door also includes a limiting component 8, which includes a limiting block 9. The limiting block 9 is movably disposed on the first mounting member 5 and / or the second mounting member 6 along the height direction of the furnace door, and the limiting block 9 protrudes from the first mounting member 5 and / or the second mounting member 6. The limiting block 9 is located between the first opening and / or the second opening and the corresponding protrusion 7.

[0037] Furthermore, the limiting assembly 8 also includes: a blocking plate 10, which is disposed at one end of the limiting plate away from the first mounting member 5 and / or the second mounting member 6; and a hand-held part 11, which is disposed on the side of the blocking plate 10 away from the limiting block 9.

[0038] By adopting the above technical solution, a movable limiting block 9 is provided on the first mounting part 5 and the second mounting part 6, and the limiting block 9 is located between the opening and the protrusion 7; the blocking effect of the limiting block 9 prevents the telescopic end of the first driving part 4 from accidentally disengaging from the corresponding opening due to misoperation, thereby improving the safety of the mechanism; by adding a hand-held part 11, it is convenient to manually operate the limiting block 9 to release the limitation.

[0039] Please refer to Figure 2 An inclined guide surface is provided on the side of the limiting block 9 away from the protrusion 7.

[0040] By adopting the above technical solution and through the inclined guide surface design, the telescopic end of the first driving member 4 can push the limiting block 9 up along the inclined surface when it contacts the limiting block 9. Then, through the limiting of the limiting block 9, the telescopic end of the first driving member 4 is limited to the first opening or the second opening, avoiding mechanical damage caused by hard collision and improving the smoothness of operation.

[0041] Please refer to Figure 3 The furnace door also includes: a furnace door moving assembly 12, which includes: a track 13 extending along the length of the furnace door and located above the furnace door; a connecting plate 14 having a moving space, with the track 13 located within the moving space; a furnace door body 1 rotatably disposed on the side of the connecting plate 14 facing away from the track 13; a second driving member 15 mounted on the connecting plate 14, with the telescopic end of the second driving member 15 located within the moving space; and a first traveling wheel 16 rolling in contact with the track 13 and drivenly connected to the second driving member 15 to drive the first traveling wheel 16 to move along the track 13.

[0042] Furthermore, the connecting plate 14 is U-shaped.

[0043] Specifically, the track 13 is preferably an I-beam, and the second drive component 15 is a motor. The specific model is selected according to the weight of the furnace door, which will not be elaborated here.

[0044] By adopting the above technical solution, the sliding cooperation between the track 13 and the connecting plate 14 enables the horizontal movement of the furnace door body 1 along the length of the furnace body, meeting the needs of multi-station operation; the rotatable connection between the furnace door body 1 and the connecting plate 14 facilitates fine adjustment of the sealing surface angle, adapting to different furnace body structures.

[0045] Please refer to Figure 3 and Figure 4 The furnace door moving assembly 12 further includes: a drive gear, which is drivenly connected to the second drive member 15; a first driven gear 17, which is rotatably disposed in the moving space and meshes with the drive gear and is connected to the first traveling wheel 16; a second driven gear 18, which is rotatably disposed in the moving space and is spaced apart along the length direction of the furnace door body 1 and meshes with the drive gear; and a second traveling wheel 19, which is disposed on the side of the second driven gear 18 away from the second drive member 15.

[0046] By adopting the above technical solution, the driving gear simultaneously meshes with the first driven gear 17 and the second driven gear 18, achieving synchronous distribution of the power from a single drive source (second drive component 15) to the first traveling wheel 16 and the second traveling wheel 19, which are spaced apart along the length of the track 13. This ensures that they achieve completely consistent rotational speeds, eliminating the risk of slippage or asynchrony caused by differences in rotational speeds between the first traveling wheel 16 and the second traveling wheel 19. This guarantees efficient transmission of driving force and linearity of movement. Furthermore, it increases the effective contact area and traction of the connecting plate 14 with the track 13, enhancing the load capacity of the entire furnace door moving assembly 12. At the same time, the dual-wheel drive disperses the force on individual wheels, reducing the possibility of wheel slippage. Especially during startup, braking, or when the load is large, it enhances the stability and reliability of movement.

[0047] Please refer to Figure 5 The furnace door moving assembly 12 further includes: a third traveling wheel 20, which rolls in contact with the side of the track 13 away from the first traveling wheel 16; the third traveling wheel 20 is rotatably disposed within the moving space, and the third traveling wheel 20 and the first traveling wheel 16 are spaced apart along the thickness direction of the furnace door body 1; a fourth traveling wheel 21, which rolls in contact with the side of the track 13 away from the first traveling wheel 16; the fourth traveling wheel 21 is rotatably disposed within the moving space, and the fourth traveling wheel 21 and the first traveling wheel 16 are spaced apart along the thickness direction of the furnace door body 1; the fourth traveling wheel 21 and the third traveling wheel 20 are spaced apart along the length direction of the furnace door body 1.

[0048] By adopting the above technical solution, the first traveling wheel 16, the second traveling wheel 19, the third traveling wheel 20 and the fourth traveling wheel 21 form distributed support on both sides of the track 13, which enhances the anti-overturning ability of the connecting plate 14; and by the wheel group spacing layout, the traveling wheels are prevented from leaving the track 13, thus improving the movement stability.

[0049] Please refer to Figure 4 A limit switch 22 is provided on the track 13, and a trigger rod 23 is provided on the connecting plate 14. When the furnace door body 1 seals the furnace chamber, the trigger rod 23 touches the limit switch 22, and the second drive member 15 stops rotating. At the same time, the furnace door body 1 stops moving, and the first opening on the first mounting member 5 and the second opening on the second mounting member 6 have passed through the telescopic end of the corresponding first drive member 4. At this time, each first drive member 4 is activated. Under the limiting action of the protrusion 7, the telescopic end of each first drive member 4 drives the first mounting member 5 and the second mounting member 6 on the furnace door body 1 to move through the protrusion 7, so as to seal the furnace door body 1 and the furnace chamber.

[0050] By adopting the above technical solution, the movement endpoint of the furnace door body 1 is precisely limited through the linkage control of the limit switch 22 and the trigger rod 23; the sealing action of the first drive component 4 is automatically triggered by the electrical signal, realizing the continuous operation of "sealing as soon as it is in place" and reducing the manual intervention link.

[0051] Working principle: The operator remotely starts the second drive component 15 (motor) of the furnace door moving assembly 12, and the motor drives the drive gear to rotate. The drive gear simultaneously meshes with the first driven gear 17 and the second driven gear 18, causing them to rotate synchronously. The first driven gear 17 drives the first traveling wheel 16 connected to it to rotate, and the second driven gear 18 drives the second traveling wheel 19 connected to it to rotate. The first traveling wheel 16 and the second traveling wheel 19 roll forward on the same side of the track 13. At the same time, the third traveling wheel 20 and the fourth traveling wheel 21 on the connecting plate 14 roll on the other side of the track 13 to provide support and guidance. The entire connecting plate 14 and the furnace door body 1, the first mounting component 5, and the second mounting component 6 carried on it move smoothly and horizontally along the length of the track 13, moving closer to the target furnace chamber position.

[0052] When the furnace door body 1 moves to the position where the furnace chamber is about to be sealed, the trigger rod 23 on the connecting plate 14 contacts the limit switch 22 installed on the track 13; the limit switch 22 sends a signal to control the second drive component 15 to stop rotating, and the first traveling wheel 16, the second traveling wheel 19 and the connecting plate 14 to stop moving horizontally; at this time, the furnace door body 1 is facing the furnace chamber opening, and the first opening on the first mounting component 5 and the second opening on the second mounting component 6 have respectively passed through the telescopic end of the corresponding first drive component 4 (at this time, the telescopic end is in the extended state, and the opening has passed its end position). During this process, the telescopic end of the first drive component 4 hits the limiting block 9 located on the first mounting component 5 and / or the second mounting component 6 (its inclined guide surface helps the telescopic end of the first drive component 4 to slide in smoothly) and finally limits it to the limiting block 9, which plays a mechanical limiting role in preventing the telescopic end of the first drive component 4 from accidentally coming out of the opening, and ensuring that the sealing pressure remains stable during the heat treatment process.

[0053] Simultaneously or shortly after the limit switch 22 is triggered, the control system activates each of the first drive components 4 (cylinders / hydraulic rods), and their telescopic ends begin to extend; the protrusions 7 on the telescopic ends then move toward the furnace door body 1.

[0054] The protruding protrusions 7 abut against the corresponding first mounting member 5 and second mounting member 6 respectively.

[0055] After the protrusion 7 abuts, the first driving member 4 applies a pulling force toward the furnace chamber to the first mounting member 5 and the second mounting member 6 through the protrusion 7, thereby driving the entire furnace door body 1 to press tightly against the sealing surface of the furnace chamber.

[0056] After the furnace heat treatment process is completed, the control system first instructs the telescopic ends of each first drive component 4 to extend; the extension action causes the protrusion 7 to disengage from the contact state with the first mounting component 5 and the second mounting component 6. At this time, by pulling the hand-held part 11 of the limiting component 8, the blocking plate 10 and the limiting block 9 can be moved, thereby releasing the limiting effect of the limiting block 9 on the telescopic ends of the first drive component 4.

[0057] The operator remotely starts the second drive component 15 to reverse; the drive gear drives the first driven gear 17 and the second driven gear 18 to rotate in the opposite direction, driving the first traveling wheel 16 and the second traveling wheel 19 to roll in the opposite direction on the track 13, while the third traveling wheel 20 and the fourth traveling wheel 21 provide support and guidance; the connecting plate 14 drives the furnace door body 1 to move horizontally away from the furnace opening along the track 13, opening the passage for loading and unloading operations.
