[0002] The furnace door of the high-temperature annular annealing furnace is located in the high-temperature zone and mainly serves to insulate against heat. During production, the furnace door needs to be frequently raised and lowered to ensure annealing time and steel coil quality. However, in actual use, the furnace door may malfunction and fail to rise properly, especially if it fails to rise properly for an extended period. This can cause the trolley to fail to rotate, which in turn affects the quality of the entire furnace of steel and results in significant losses. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a furnace door failure replacement and processing device. This device can replace the original mechanism used to drive the furnace door to lift when the furnace door cannot be lifted normally, thereby replacing the drive for lifting the furnace door.

[0005] The technical solution adopted to achieve the purpose of this application is as follows:

[0006] The furnace door malfunction replacement device of this application includes a frame, a steering assembly, a winding drive, and a connector. The frame is installed below the counterweight of the furnace door, and the steering assembly is located inside the frame. The winding drive is located beside the frame and spaced apart from it. The connector overlaps the steering assembly and achieves steering in the extension direction at the steering assembly. One end of the connector is connected to the counterweight, and the other end is connected to the winding drive. When the furnace door cannot be raised, the winding drive is used to pull the counterweight downward through the connector to lift the furnace door.

[0007] In some technical solutions, the connector includes a first extension section and a second extension section. The first extension section is connected to the counterweight, and the second extension section is connected to the winding drive. The extension directions of the first extension section and the second extension section are arranged perpendicularly.

[0008] In some technical solutions, the first extension section is arranged vertically, and the second extension section is arranged horizontally.

[0010] In some technical solutions, the frame further includes a top frame, which is connected between the first side frame and the second side frame and located on the top side of the frame, and the connector passes through the top frame and the second side frame.

[0011] In some technical solutions, the steering component includes:

[0012] Steering bracket, the steering bracket being fixed to the first side frame;

[0013] A rotating component is rotatably mounted on the steering bracket, and a connecting component is attached to the rotating component and the steering in the extension direction is achieved through the rotating component.

Detailed Implementation

[0022] To enable those skilled in the art to better understand this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] In this embodiment of the application, the furnace door fault replacement treatment device (hereinafter referred to as the treatment device 100) includes a frame 110, a steering assembly 120, a winding drive 130, and a connector 140.

[0024] The frame 110 is installed below the counterweight 200 of the furnace door, for example, as... Figure 1 As shown, the frame 110 can be rectangular, and its material can be steel or other materials. Specifically, it can be assembled and welded from I-beams. In some other embodiments, the frame 110 can also be made of high-strength plastic or other materials. The frame 110 can be installed directly below the counterweight 200 of the furnace door by means of fasteners such as screws. In some other embodiments, the frame 110 can also be staggered relative to the counterweight 200.

[0025] It should be noted that the various orientations of the processing device described in this application refer to the actual orientations of the processing device after installation. The up and down direction is the vertical direction in actual working conditions. The left side from bottom to top is left, the right side from bottom to top is right, the front side from bottom to top is front, and the rear side from bottom to top is rear.

[0026] The steering assembly 120 is housed within the frame 110. For example, the steering assembly 120 may include a round shaft that can be fixed within the frame 110, thereby protecting the steering assembly 120 from easy contact during operation.

[0027] The winding drive 130 is located on the side of the frame 110 and is spaced apart from the frame 110. For example, the winding drive 130 can be located on the right side of the frame 110, and the winding drive 130 can be spaced apart from the frame 110 in the left and right directions. The winding drive 130 can be a device or equipment with winding function, such as a roll.

[0028] The connector 140 engages with the steering assembly 120 and enables steering in the direction of extension at the steering assembly 120, for example, as... Figure 1 As shown, the connector 140 can be a high-strength rope such as a steel wire rope that can meet the traction requirements. The connector 140 can bypass the circular shaft of the aforementioned steering assembly 120, and the connector 140 can change its extension direction at this circular shaft.

[0029] One end of the connector 140 is connected to the counterweight 200, and the other end of the connector 140 is connected to the winding drive 130. When the furnace door cannot be lifted, the winding drive 130 is used to pull the counterweight 200 to move through the connector 140 to drive the furnace door to lift.

[0030] For example, such as Figure 1 As shown, the connector 140 has two free ends, namely the top end and the right end of the connector 140. The top end of the connector 140 can be directly connected to the counterweight 200, and the right end of the connector 140 can be directly connected to the winding drive 130.

[0031] When the original lifting mechanism of the furnace door malfunctions, the winding drive 130 can be activated. The running winding drive 130 can wind and pull the connecting piece 140, thereby pulling the counterweight 200 through the moving connecting piece 140, and thus lifting the furnace door. This avoids the situation in the prior art where the furnace door cannot be lifted normally for a long time, which can easily delay production and ensure the continuity of production.

[0032] In some embodiments, the connector 140 includes a first extension 1401 and a second extension 1402. The first extension 1401 is connected to the counterweight 200, and the second extension 1402 is connected to the winding drive 130. The extension directions of the first extension 1401 and the second extension 1402 are arranged perpendicularly.

[0033] For example, such as Figure 1 As shown, depending on the direction of extension, the connector 140 can be divided into two sections: a first extension section 1401 and a second extension section 1402. The first extension section 1401 and the second extension section 1402 can be arranged at an angle. Specifically, the first extension section 1401 can be arranged roughly vertically, while the second extension section 1402 can be arranged roughly horizontally, meaning the angle formed by the first extension section 1401 and the second extension section 1402 can be a right angle. This facilitates the turning connection between the counterweight 200 and the winding drive 130.

[0034] In some embodiments, the frame 110 includes a first side frame 1101 and a second side frame 1102 arranged opposite to each other, the second side frame 1102 being located between the first side frame 1101 and the winding drive 130, and a steering assembly 120 being disposed on the first side frame 1101.

[0035] For example, such as Figure 1 As shown, the frame 110 can be generally rectangular. The first side frame 1101 can be the left side of the frame 110, and the second side frame 1102 can be the right side of the frame 110. The aforementioned winding drive 130 can be located on the right side of the second side frame 1102. The aforementioned steering assembly 120 can be installed on the first side frame 1101 and located between the first side frame 1101 and the second side frame 1102.

[0036] Since the second extension 1402 exerts a force on the steering assembly 120, the installation arrangement of the steering assembly 120 can be adapted to the direction of the force exerted by the second extension 1402. This also avoids the situation where the steering bracket 1201 is easily interfered with by the second extension 1402 when it is subsequently installed on the second side frame 1102, thus improving the stability of the traction movement of the connector 140.

[0037] In some embodiments, the frame 110 includes a top frame 1103 connected between a first side frame 1101 and a second side frame 1102 and located on the top side of the frame 110, with a connector 140 passing through the top frame 1103 and the second side frame 1102.

[0038] For example, such as Figure 1 As shown, the top frame 1103 is the top side portion of the frame 110. The left side of the top frame 1103 can be connected to the first side frame 1101, and the right side of the top frame 1103 can be connected to the second side frame 1102. Both the top frame 1103 and the second side frame 1102 can be provided with through holes for the connector 140 to pass through. During assembly, the first extension section 1401 can pass through the through hole on the top frame 1103, and the second extension section 1402 can pass through the through hole on the second side frame 1102, thereby facilitating the installation and arrangement of the connector 140.

[0039] In some other embodiments, the top frame 1103 and the second side frame 1102 may also be in the shape of a box. In this case, the first extension 1401 and the second extension 1402 may pass through the corresponding holes on the top frame 1103 and the second side frame 1102, respectively.

[0040] In some embodiments, the steering assembly 120 includes a steering bracket 1201 and a rotating member 1202. The steering bracket 1201 is fixed to the first side frame 1101, the rotating member 1202 is rotatably mounted on the steering bracket 1201, and the connecting member 140 is attached to the rotating member 1202 and the steering in the extension direction is achieved through the rotating member 1202.

[0041] For example, such as Figure 1As shown, the steering bracket 1201 can be a triangular bracket. One vertex of the steering bracket 1201 can be used to assemble the rotating component 1202, and the edge of the steering bracket 1201 corresponding to the vertex can be connected and fixed to the first side frame 1101. The connection and fixing method can be fasteners such as screws. In some other embodiments, the steering bracket 1201 can also be fixed by welding, bonding, etc.

[0042] The rotating component 1202 can be a rotating shaft. For example, the steering bracket 1201 can include two triangular end plates arranged opposite each other in the front-rear direction. The rotating component 1202 can be rotatably mounted between the two end plates, and the axial direction of the rotating component 1202 can be in the front-rear direction.

[0043] During assembly, the connector 140 can pass through the two end plates and bypass the rotating member 1202. When the winding drive 130 drives the connector 140 to move, the rotating member 1202 will rotate on its own under the drive of the bend of the connector 140, thereby ensuring the smooth movement of the connector 140.

[0044] In some other embodiments, the rotating member 1202 can be a round shaft, and the rotating member 1202 can be directly fixed on the steering bracket 1201, that is, the rotating member 1202 cannot rotate relative to the steering bracket 1201, but the surface of the rotating member 1202 is a smooth surface. In this case, the connecting member 140 can directly bypass the rotating member 1202.

[0045] In some embodiments, such as Figure 1 As shown, the rotating component 1202 is a pulley. The rotating component 1202 is rotatably mounted between the two end plates of the aforementioned steering bracket 1201, and the axial direction of the pulley can be in the front-to-back direction. Optionally, an annular groove can be provided on the outer periphery of the pulley, and the annular groove can extend and close around the circumference of the pulley to form a circle. The aforementioned connecting component 140 can be embedded in the annular groove, thereby preventing the connecting component 140 from moving in the front-to-back direction during movement and ensuring the structural stability of the assembly of the connecting component 140 and the rotating component 1202.

[0046] In some embodiments, the winding drive 130 includes a winding bracket 1301 and a winch 1302, wherein the winding bracket 1301 is fixed to the ground, and the winch 1302 is mounted above the winding bracket 1301. For example, as Figure 1 As shown, the winding bracket 1301 can also be a triangular bracket, a square bracket, a platform, etc. The winding bracket 1301 can be directly fixed to the ground, and the winch 1302 can be directly installed above the winding bracket 1301. With the support of the winding bracket 1301, the winch 1302 and the aforementioned steering assembly 120 are kept at roughly the same level.

[0047] In some embodiments, the frame 110 is installed at a position lower than the lowest point where the counterweight 200 descends during use. For example, the lowest point of the counterweight 200 during use may be 0.5m above the ground, in which case the frame 110 can be installed approximately 0.4m above the ground. This avoids collisions between the counterweight 200 and the frame 110.

[0048] In some embodiments, the connector 140 may be a steel wire rope with a diameter of 20 mm. The end of the connector 140 may be provided with a connecting joint specifically for connecting the steel wire rope to the counterweight 200 or the winch 1302. Since the connecting joint is large in size, during assembly, the steel wire rope may be first assembled into the steering bracket 1201, and then the rotating part 1202 may be assembled onto the steering bracket 1201.

[0049] In some embodiments, the distance between the frame 110 and the winding drive 130 can be 3.5m, and the distance between the frame 110 and the winding drive 130 can be adjusted according to the lowest position of the counterweight 200, etc.

[0050] The furnace door system of this application is described below.

[0051] The furnace door system of this application includes a processing device 100, a furnace door, and a counterweight 200. The processing device 100 can be the processing device 100 described in any of the above embodiments. The counterweight 200 is connected to the furnace door, and the connector 140 of the processing device 100 is connected to the counterweight 200.

[0052] It should be noted that the furnace door is equipped with a dedicated drive mechanism, which enables the furnace door to be lifted during use. The counterweight 200 can be connected to the furnace door via a chain or similar means. When the drive mechanism lifts the furnace door, the counterweight 200 can counteract part of the driving force of the drive mechanism. If the drive mechanism malfunctions, the furnace door cannot be lifted normally during production. In this case, the winding drive 130 of the processing device 100 can be activated. The winding drive 130 can pull the connecting piece 140 to move, thereby causing the counterweight 200 to move downwards, thus enabling the furnace door to be lifted.

[0053] In some embodiments, the counterweight 200 is provided with a hook 300, which is located on the bottom side of the counterweight 200, and the connector 140 is connected to the hook 300. For example, as Figure 2 As shown, a pull rod or other structural component can be provided at the center of the counterweight 200. The bottom of the pull rod can be fixed with the aforementioned hook 300, which can be a hook, a hanging ring, etc. The top end of the first extension 1401 of the connector 140 can be directly connected to the hook 300, thereby facilitating the connection between the connector 140 and the counterweight 200.

[0054] Through the above embodiments, this application has the following beneficial effects or advantages:

[0055] 1) When the original drive mechanism specifically used to lift the furnace door fails, the processing device of this application can replace the existing drive mechanism in a timely manner, thereby enabling the furnace door to be lifted with the help of the processing device. This avoids the situation where the furnace door cannot be lifted for a long time, which would cause the trolley to fail to rotate and also avoids the impact on the furnace steel, thus reducing losses.

[0056] 2) The processing device of this application can temporarily replace the original drive mechanism, thereby allowing the original drive mechanism to be replaced and gaining a relatively long time for emergency repair, which reduces the impact on production and avoids the contradiction between emergency repair and continuous production in the prior art, thus ensuring the continuity of production.
