Description

Technical Field

[0001] This utility model relates to the technical field of partition curtain doors, and in particular to a heat-resistant partition curtain door. Background Technology

[0002] A walking beam furnace is an industrial heat treatment equipment that uses a walking mechanism to continuously transport materials. It mainly consists of a fixed furnace bed, a liftable walking beam, and a multi-layer pallet system. Both sides of the heat treatment zone in the walking beam furnace are equipped with partition curtains. However, in actual use, it has been found that the large temperature difference between the two sides of the partition curtains can make them difficult to open. Utility Model Content

[0003] To facilitate the opening and closing of the partition curtain door located in the walking beam furnace, this application provides a heat-resistant partition curtain door.

[0004] This application provides a heat-resistant partition curtain door, which adopts the following technical solution: A heat-resistant partition curtain door, characterized in that it includes a frame and multiple gate panel assemblies, the multiple gate panel assemblies being arranged along the height direction of the frame to form a curtain door section, a fixed roller and a movable roller being rotatably connected to both ends of the curtain door section, the fixed roller being fixedly mounted on the side of the frame away from the ground, each gate panel assembly including an upper panel and a lower panel rotatably connected, each upper panel and lower panel having mounting tubes on both sides, the mounting tubes on the upper panel and the lower panel being staggered, a guide roller being provided between two adjacent gate panel assemblies, the inner diameter of the mounting tubes being adapted to the fixed roller, the movable roller and the guide roller, the frame having a control mechanism for driving the movable roller to slide along a guide groove, each end of the movable roller and the guide roller being rotatably connected to a rotating wheel, and the frame having corresponding guide grooves for rotational sliding.

[0005] By adopting the above technical solution, when the moving roller slides along the length of the guide groove under the action of the control mechanism, it can drive the upper and lower pieces to rotate, thereby achieving the effect of controlling the opening and closing of the curtain door. This opening and closing method effectively reduces the impact of the temperature difference on both sides of the partition curtain door on the opening and closing of the partition curtain door. The rotating wheel cooperates with the guide groove to provide guidance and limit for the sliding of the moving roller and the guide roller, improving the stability and reliability of the opening and closing of the curtain door.

[0006] Preferably, it further includes a control plate disposed at the top of the frame. The control mechanism includes a control block slidably disposed on the frame. The top of the control block is in contact with the moving roller. The control block is provided with a control rod. The top of the frame and the control plate are both provided with control grooves for the control rod to slide. The control plate is rotatably provided with a control gear. The control rod is provided with a control rack that meshes with the control gear. The control plate is provided with a control component for driving the control gear to rotate.

[0007] By adopting the above technical solution, the control component drives the control gear to rotate, thereby causing the control block to slide under the action of rack and pinion transmission. This facilitates the control of the sliding length of the control block and can ensure the stability of the opening and closing of the curtain door to a certain extent.

[0008] Preferably, there are two sets of control mechanisms, which are symmetrically arranged on both sides of the curtain door. A synchronization roller is provided between the control gears in the two sets of control components, and the control gears are coaxially arranged on the synchronization roller.

[0009] By adopting the above technical solution, the setting of two sets of control mechanisms ensures the stability of the opening and closing of the curtain door. The setting of synchronous rollers ensures that the rotation speed of the control gears located on both sides of the curtain door is consistent, further ensuring the stability of the opening and closing of the curtain door.

[0010] Preferably, the control component includes a drive rack slidably disposed on the control plate, a drive gear coaxially disposed on the synchronous roller and meshing with the drive rack, and a drive element for controlling the sliding of the drive rack on the control plate.

[0011] By adopting the above technical solution, the sliding of the drive rack can be controlled by the drive component, which can drive the synchronous roller to rotate under the action of gear transmission, making it easier to control the timing of the synchronous roller's rotation.

[0012] Preferably, a control wheel is rotatably connected to the control block, and the sidewall of the control wheel is in contact with the inner side of the frame.

[0013] By adopting the above technical solution and setting the control wheel, the distance between the control block and the frame can be effectively controlled, making it less likely for the control block to collide and rub against the frame, thus ensuring the stability of the opening and closing of the curtain door.

[0014] Preferably, both the upper and lower sheets are arranged in a Z-shape.

[0015] By adopting the above technical solution, the strength of the constructed curtain door is guaranteed.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. When the moving roller slides along the length of the guide groove under the action of the control mechanism, it can drive the upper and lower pieces to rotate, thereby achieving the effect of controlling the opening and closing of the curtain door. This opening and closing method effectively reduces the impact of the temperature difference on both sides of the partition curtain door on the opening and closing of the partition curtain door.

[0020] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0021] This application discloses a heat-resistant partition curtain door, referring to... Figure 1 and Figure 2 It includes a frame 1 and multiple gate panel groups 2. The multiple gate panel groups 2 are arranged along the height direction of the frame 1 to form a curtain door section 3. The number of gate panel groups 2 depends on the height of the frame 1. In this embodiment, six gate panel groups 2 are selected as an example. The two ends of the curtain section 3 are respectively rotatably connected to a fixed roller 31 and a movable roller 32. The fixed roller 31 is fixed on the side of the frame 1 away from the ground. The gate plate group 2 includes an upper plate 21 and a lower plate 22 rotatably connected. The upper plate 21 and the lower plate 22 are both arranged in a Z shape, which ensures the strength of the curtain section 3 to a certain extent. The upper plate 21 and the lower plate 22 are both welded and fixed with mounting tubes 23. The mounting tubes 23 on the upper plate 21 and the mounting tubes 23 on the lower plate 22 are staggered. A guide roller 4 is provided between two adjacent gate plate groups 2. The inner diameter of the mounting tube 23 is compatible with the fixed roller 31, the movable roller 32 and the guide roller 4. The two adjacent gate plate groups 2 are connected by the guide roller 4, and the two adjacent gate plate groups 2 rotate about the guide roller 4 as the rotation axis.

[0022] Reference Figure 1 and Figure 2 A rotating roller is provided between the upper panel 21 and the lower panel 22 in the same gate panel group 2. The rotating roller is located on the side of the curtain section 3 away from the guide roller 4, and the rotating roller is staggered with the guide roller 4. The rotating roller passes through the mounting tube 23 of the corresponding upper panel 21 and lower panel 22, so the upper panel 21 and lower panel 22 rotate about the rotating roller as the axis of rotation. Both ends of the moving roller 32 and the guide roller 4 are rotatably connected to rotating wheels 321. The frame 1 is provided with corresponding guide grooves for the sliding of the rotating wheels 321. The rotating wheels 321 cooperate with the guide grooves to provide guidance and limit for the sliding of the moving roller 32 and the guide roller 4, thereby improving the stability and reliability of the opening and closing of the curtain section 3.

[0023] Reference Figure 1 and Figure 2 The frame 1 is equipped with a control mechanism for driving the moving roller 32 to slide along the guide groove. The partition curtain door also includes a control plate 5 set at the top of the frame 1. The control plate 5 is fixed on other carriers. The control mechanism includes a control block 51 slidably set on the frame 1. The top of the control block 51 is attached to the moving roller 32. The moving roller 32 can be fixed to the control block 51 by welding. A control rod 52 is fixed on the control block 51. A control groove for the control rod 52 to slide is opened through the top of the frame 1 and the control plate 5. The sliding of the control rod 52 can drive the control block 51 to slide. When the control block 51 slides, it can drive the moving roller 32 to slide at the same time. This effectively reduces the impact of the temperature difference on both sides of the partition curtain door on the opening and closing of the partition curtain door, thereby achieving the effect of facilitating the control of the opening and closing of the curtain door 3.

[0024] Reference Figure 1 and Figure 2 A control gear 53 is rotatably mounted on the control plate 5, and a control rack 531 meshes with the control gear 53 on the control rod 52. When the control gear 53 rotates, the control rod 52 can slide along the gear transmission. To ensure the stability of the sliding of the control rod 52, multiple limiting plates 54 are provided on the control rod 52. The limiting plates 54 have through holes for the control rod 52 to slide. The control plate 5 is provided with a control tube 521 for the control rod 52 to pass through. The control tube 521 has corresponding control grooves 522 for the control gear 53 to mesh with the control rack 531.

[0025] Reference Figure 1 and Figure 2 A control wheel 511 is rotatably connected to the control block 51. The side wall of the control wheel 511 is in contact with the inner side of the frame 1. By setting the control wheel 511, the distance between the control block 51 and the frame 1 can be effectively controlled, so that the control block 51 is not easy to collide and rub against the frame 1, thus ensuring the stability of the opening and closing of the curtain door 3. The limiting plate 54 located at the bottom can not only ensure the stability of the sliding of the control rod 52, but also limit the length of the sliding of the control block 51, thus ensuring the normal use of the partition curtain door.

[0026] Reference Figure 1 and Figure 2To improve the stability of the opening and closing of the curtain door 3, there are two sets of control mechanisms. The two sets of control mechanisms are symmetrically arranged on both sides of the curtain door 3. A synchronous roller 55 is provided between the control gears 53 in the two sets of control components. The control gears 53 are coaxially arranged on the synchronous roller 55. Through the arrangement of the synchronous roller 55, the rotation speed of the control gears 53 on both sides of the curtain door 3 is consistent, which further ensures the stability of the opening and closing of the curtain door 3. The control plate 5 is provided with a synchronous bearing 551 to support the synchronous roller 55, ensuring the stability of the rotation of the synchronous roller 55.

[0027] Reference Figure 1 and Figure 2 The control plate 5 is equipped with a control component for driving the control gear 53 to rotate. The control component includes a drive rack 56 slidably disposed on the control plate 5, and a drive block 561 corresponding to the drive rack 56 on the control plate 5. The drive block 561 has a drive groove for the drive rack 56 to slide. The setting of the drive block 561 ensures the stability of the sliding of the drive rack 56. The synchronous roller 55 is coaxially provided with a drive gear 57 that meshes with the drive rack 56. The control plate 5 is provided with a drive component for controlling the sliding of the drive rack 56. In this embodiment, the drive component is a drive cylinder 58. The drive cylinder 58 is fixed on the control plate 5. The piston rod of the drive cylinder 58 is fixed to the drive rack 56. The drive rack 56 is driven to slide by the drive cylinder 58, so that the synchronous roller 55 drives the control gear 53 to rotate under the action of gear transmission, which facilitates the control of the rotation of the control gear 53.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
