The gate used to block the atmosphere between the open flame section and the reduction section is often raised during the strip threading process. Due to its large size and weight, the gate is difficult to raise and lower, typically requiring manual or crane lifting. However, manual lifting is unsafe, time-consuming, and labor-intensive, while crane lifting is inconvenient. Utility Model Content

When the gate 200 moves downward, the bottom of the gate 200 is suitable for contacting the upper surface of the steel strip.
[0023] Specifically, in order to allow the steel strip to pass through the shell 100, the shell 100 is set to a rectangular structure with a hollow middle part; the gate plate 200 is set in the upper half of the shell 100. This setting divides the shell 100 into two parts to facilitate the subsequent production of the steel strip; in order to enable the mortgage gate plate 200 to move up and down, an oil lifting column 310 is set, and the lifting column 310 is set at the top of the gate plate 200. The bottom of the lifting column 310 is welded to the top of the gate plate 200, and the lifting column 310 drives the gate plate 200 to move up and down when it is raised and lowered.
[0024] In a possible implementation, a sealed chamber 110 is provided on the top of the housing 100 , a lifting column 310 passes through the top of the sealed chamber 110 and is connected to the gate 200 , and the gate 200 can move up and down in the sealed chamber 110 .
[0025] Specifically, such as Figure 2 As shown, in order to prevent air from entering the housing 100 when the gate 200 moves up and down, a sealed chamber 110 is provided at the top of the housing 100. The lifting column 310 passes through the top of the sealed chamber 110 to drive the gate 200 to move up and down in the sealed chamber 110, ensuring that air is prevented from entering the housing when the gate 200 moves up and down.
[0026] In one possible implementation, a nitrogen sealing sleeve 111 is provided at the connection position between the top of the sealed chamber 110 and the lifting column 310 to prevent air from entering the shell 100 when the lifting column 310 moves up and down; a fixing block 210 is provided at the top of the gate plate 200, and the lifting column 310 is fixed to the top of the gate plate 200 through the fixing block 210.
[0027] Specifically, such as Figure 2As shown, because there is a certain gap between the lifting column 310 and the sealed chamber 110 when the lifting column 310 moves up and down, in order to prevent air from entering through the gap, a nitrogen sealing sleeve 111 is provided at the connection position between the top of the sealed chamber 110 and the lifting column 310. Nitrogen is filled in the nitrogen sealing sleeve 111 to prevent air from entering the shell 100 when the lifting column 310 moves up and down; in order to better connect the gate plate 200 with the lifting column 310, a fixing block 210 is provided on the top of the gate plate 200, and the lifting column 310 is fixed to the top of the gate plate 200 through the fixing block 210.
[0028] In a possible implementation, a spiral elevator 320 is further included, and the upper end of the lifting column 310 is connected to the spiral elevator 320 .
[0029] Specifically, such as Figure 2 As shown, the lifting group includes a lifting column 310, a spiral elevator 320 and a support rod 330. The lower end of the lifting column 310 is connected to the top of the gate plate 200, and the upper end of the lifting column 310 is connected to the spiral elevator 320. The spiral elevator 320 and the lifting column 310 are connected through a universal joint 360. The spiral elevator 320 drives the lifting column 310 to move up and down, so that the lifting column 310 drives the gate plate 200 to move up and down.
[0030] In a possible implementation, there are multiple lifting columns 310 and multiple spiral elevators 320 , and a connecting rod 330 is provided between every two spiral elevators 320 . Each two spiral elevators 320 are connected via a universal coupling 360 .
[0031] Specifically, such as Figure 2 As shown, because the gate plate 200 has a certain width, the number of the lifting columns 310 and the spiral lifters 320 is multiple, which can better drive the gate plate 200 to move up and down.
[0032] In a possible implementation, it also includes a motor 340 and a support frame 350; the motor 340 is arranged at the upper end of the support frame 350, and the motor 340 and the screw elevator 320 are connected through a universal coupling 360; a universal coupling 360 is arranged between the motor 340 and the screw elevator 350.
[0033] Specifically, such as Figure 2 As shown, it also includes a motor 340 and a support frame 350; the motor 340 is used to provide electricity, and the support frame 350 is used to support the motor 340. The motor 340 is arranged at the upper end of the support frame 350 so that the motor 340 and the screw elevator 320 are at the same height. A universal coupling 360 is provided between the motor 340 and the screw elevator 350, and the motor 340 transmits electricity to the screw elevator 320 through the universal coupling 360.
[0034] In a possible implementation, a limit plate 370 is provided on the support frame 350 , a scale is engraved on the limit plate 370 , and a sensor 371 is provided on the limit plate 370 , and the sensor 371 is connected to the motor 340 by an electric wire.
[0035] Specifically, such as Figures 1 to 2 As shown, in order to be able to lift the height, a limit plate 370 is provided on the support frame 350, and a scale is engraved on the limit plate 370. Such a setting can observe the lifting height. A sensor 371 is provided on the limit plate 370. When the lifting height reaches the specified height, the sensor 371 transmits a signal to the motor 360, and the motor 360 stops supplying power, causing the spiral elevator 320 to stop rising.
[0036] In one possible implementation, it also includes a direct combustion section 410 and a reduction section 420; the direct combustion section 410 is arranged on one side of the shell 100 and is sealed with the shell 100, for heating the steel strip; the reduction section 420 is arranged on the opposite side of the shell 100 and the direct combustion section 410, and is sealed with the shell 100, for reducing the oxide film on the surface of the steel strip into a pure iron layer; a furnace bottom roller 120 is arranged in the shell 100, and the furnace bottom roller 120 is in rolling contact with the lower surface of the steel strip; a collecting bin 130 is arranged in the shell 100, and the furnace bottom roller 120 is arranged on the top entrance of the collecting bin 130.
[0037] Specifically, such as Figures 1 to 2 As shown, the direct combustion section 410 is used to heat the steel strip, and the reduction section 420 is used to eliminate the oxide film on the surface of the steel strip. In order to enable the steel strip to move in the shell 100, a hearth roller 120 is provided in the shell 100. The hearth roller 120 is in rolling contact with the lower surface of the steel strip, and the hearth roller 120 drives the steel strip to move while rolling.
[0038] When the present application is used, the gate plate 200 moves upward through the lifting column 310, and the steel strip first enters the direct combustion section 410 for combustion. At this time, the gate plate 200 moves downward through the lifting column 310 and is connected to the top of the steel strip. The steel strip enters the reduction section 420 through the rolling of the furnace bottom roller 120. When the steel strip breaks in the shell 100, the gate plate 200 needs to be raised again, the broken steel strip is taken out, and the new steel strip is put in. The gate plate 200 is lowered and the production of the new steel strip is started.
[0039] The present application sets the shell 100 as a rectangular parallelepiped structure with a hollow middle portion, and the steel strip passes through the hollow position of the shell 100 and penetrates the shell 100. Such a setting enables the steel strip to pass through the shell 100 to produce the steel strip; the gate plate 200 is set in the upper half of the shell 100, and the gate plate 200 is a plate-shaped structure. Because the shell 100 is a rectangular parallelepiped structure, the gate plate 200 must also be a plate-shaped structure to better adapt to the shell 100; the lifting column 310 is set at the top of the gate plate 200, and the bottom of the lifting column 310 is welded to the top of the gate plate 200. The lifting column 310 moves up and down while driving the gate plate 200 to move up and down. When the gate plate 200 moves downward, the bottom of the gate plate 200 is suitable for connection with the upper surface of the steel strip. When the steel strip breaks and a new steel strip needs to be produced, the lifting column 310 drives the gate plate to move upward, avoiding the use of manual labor or a crane to move the gate plate up and down;
[0040] The sealing chamber 110 and the nitrogen sealing sleeve 111 are provided to prevent air from entering the shell 100 when the lifting group moves up and down. The limit block 370 and the sensor 371 are provided on the support frame 350 to enable the lifting group to automatically stop rising after it is lifted to the set height. Through the above settings, the lifting group in this application drives the gate plate 200 to move up and down, solving the problems of unsafe manual lifting or labor-consuming and time-consuming crane lifting.
[0041] The above description is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and concept of the present invention, should be covered by the protection scope of the present invention.
