Description

Technical Field

[0001] This application relates to the field of steel production technology, and in particular to a device and method for changing the state of a scrap material flipper. Background Technology

[0002] Due to limited production line space, the scrap collection device of Shougang Jingtang's 1420mm continuous annealing unit is designed with a scrap hopper that is perpendicular to the production line and moves longitudinally. The scrap hopper enters a waiting-to-collect state before the strip head shearing, according to process requirements. Since the first transport channel is the upper channel and the second transport channel is the lower channel, the scrap from the cross-cutting shear cannot fall directly into the scrap hopper. Therefore, a scrap hopper is designed at the cross-cutting point of the first transport channel. The scrap from the strip head shearing first falls into the scrap hopper. Once the number of pieces reaches the process-set number, the scrap hopper tilts longitudinally, dumping the collected scrap into the scrap hopper. However, due to poor strip head shape, scrap often piles up on the hopper and does not completely fall into the scrap hopper. This results in the following defects: 1. After the scrap piles up, operators need to enter the scrap hopper area to handle the scrap, which is detrimental to worker safety. 2. Falling scrap steel can land on the strip steel in the second transport channel, causing abnormal speed reduction or even a shutdown. Furthermore, as the process speed continues to stabilize and increase, the inlet production stage becomes crucial. The first transport channel at the inlet shears the strip head in 20m increments, with each cut cutting 1m. The scrap tipper tilts every 5 cuts, taking approximately 2 minutes and 20 seconds to complete the shearing. The first transport channel takes about 2 minutes to shear 20 meters, 20 seconds longer than the second transport channel. The longer the strip head is sheared, the greater the time difference. If there are abnormalities requiring multiple cuts of 50m-200m, the first cross-cutting shear cannot collect scrap longer than 1.2m, causing a speed reduction to accommodate the shearing time. This takes approximately 6-24 minutes. In the second transport channel, if a strip head needs to be sheared for 50m-200m, it can be manually moved in large quantities to the scrap hopper, taking approximately 5-12 minutes. Overall, the shearing time of the first transport channel is 1-12 minutes longer than that of the second transport channel, which seriously restricts the production rhythm of the process.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] Please refer to the attached document. Figs. 1-4 This application provides a device for changing the state of a waste material flapper, comprising:

[0036] Rack 1;

[0037] First transport corridor 2;

[0038] The second transport channel 3, the first transport channel 2 and the second transport channel 3 are both fixedly connected to the frame 1, and the first transport channel 2 is located above the second transport channel 3;

[0039] Waste tipping plate 4 is located below the first transport channel 2 and is rotatably connected to the frame 1;

[0040] Hydraulic cylinder 5, one end of which is fixedly connected to frame 1 and the other end is fixedly connected to waste material flap 4. The output end of hydraulic cylinder 5 can lift waste material flap 4 and change the tilt angle formed between waste material flap 4 and the horizontal plane.

[0041] The controller is electrically connected to the hydraulic cylinder 5. The controller controls the hydraulic cylinder 5, which in turn controls the tilt angle between the waste material flap 4 and the horizontal plane, and changes the state of the waste material flap 4, keeping it tilted. Specifically, the controller can be a programmable controller. The control program is input into the programmable controller to control the hydraulic cylinder 5, thereby controlling the tilt angle between the waste material flap 4 and the horizontal plane, and changing the state of the waste material flap 4, keeping it tilted.

[0042] This application provides a device and method for changing the state of a scrap tipper. The controller controls the hydraulic cylinder 5, which in turn controls the tilt angle between the scrap tipper 4 and the horizontal plane, thus changing the state of the scrap tipper 4. This eliminates the need for the scrap tipper 4 to tilt longitudinally. The scrap tipper 4 remains tilted, collecting scrap steel while simultaneously allowing it to fall directly into the scrap hopper 11. This avoids problems such as abnormal speed reduction or stoppage, scrap steel falling into the second transport channel 3, scrap steel accumulating at the scrap tipper 4, and safety hazards for operators entering confined spaces to handle scrap steel. This improves work efficiency and safety.

[0043] In a preferred embodiment of the present invention, a protective net 7 is provided between the first transport channel 2 and the second transport channel 3. The protective net 7 is connected to the frame 1 and divides the first transport channel 2 and the second transport channel 3 at the cross-cutting shear, thus completely solving the problem of scrap steel falling into the second transport channel 3, reducing the frequency of scrap steel falling outside the scrap steel flip plate, avoiding abnormal shutdown or speed reduction accidents of the production line, and meeting the requirements of stable operation.

[0044] In a preferred embodiment of the present invention, the scrap tipper 4 is provided with baffles on both sides, and the baffles are fixedly connected to the scrap tipper 4. The baffles further prevent scrap steel from falling into the second transport channel 3, thus avoiding abnormal shutdown or speed reduction accidents of the production line. Furthermore, one end of the scrap tipper 4 is connected to the frame 1, and the other end forms an inclined angle with the horizontal plane and remains in an inclined state. Furthermore, the scrap tipper 4 is provided with a scrap collection trough, which collects scrap steel. Since the scrap tipper 4 is in an inclined state, the scrap steel is collected by the scrap collection trough and directly falls into the scrap hopper 11, eliminating the need for the scrap tipper 4 to tilt longitudinally and improving work efficiency.

[0045] In a preferred embodiment of the present invention, the first transport channel 2 includes:

[0046] Belt motor 8 is fixedly connected to frame 1;

[0047] The conveyor belt 9 is fixedly connected to the belt motor 8. The belt motor 8 drives the conveyor belt 9 to move. The conveyor belt 9 is used to transport steel strips.

[0048] In a preferred embodiment of the present invention, a supporting angle iron 10 is included. The supporting angle iron 10 is disposed on one side of the hydraulic cylinder 5. One end of the supporting angle iron 10 is fixedly connected to the waste material flap 4, and the other end is fixedly connected to the frame 1. Since the hydraulic cylinder 5 is tilted to support the waste material flap 4 for a long time, the waste material flap 4 may slip under the hydraulic cylinder 5 in a tilted state for a long time. The supporting angle iron 10 also has a supporting function for the waste material flap 4, so as to prevent the hydraulic cylinder 5 from slipping.

[0049] In a preferred embodiment of the present invention, a waste hopper 11 is provided below the first transport channel 2 and is fixedly connected to the frame 1 in an inclined manner; a waste collection trough collects scrap steel. Since the waste flap 4 is in an inclined state, the waste collection trough collects scrap steel and allows the scrap steel to fall directly into the waste hopper 11 at the same time.

[0050] Based on the same inventive concept, this application also provides a method for changing the state of the waste flipper 4, the method of changing the state of the waste flipper 4 includes:

[0051] Step 1: Install a protective net 7 between the first transport channel 2 and the second transport channel 3. The protective net 7 divides the cross-cutting points of the two channels to prevent scrap steel from falling into the second transport channel 3. The scrap steel turning plate is heightened by installing baffles on the sides to further prevent scrap steel from falling into the second transport channel 3 and avoid causing abnormal shutdown or speed reduction accidents on the production line.

[0052] Step 2: The controller controls the hydraulic cylinder 5, which controls the tilt angle between the scrap tipper 4 and the horizontal plane, and changes the state of the scrap tipper 4. The scrap tipper 4 remains tilted, eliminating the need for the longitudinal tilting process. While collecting scrap steel, the scrap tipper 4 directly allows the scrap steel to fall into the scrap hopper 11, avoiding abnormal speed reduction or stoppage accidents.

[0053] This application provides a device and method for changing the state of a scrap tipper. The controller controls the hydraulic cylinder 5, which in turn controls the tilt angle between the scrap tipper 4 and the horizontal plane, thus changing the state of the scrap tipper 4. This eliminates the need for the scrap tipper 4 to tilt longitudinally. The scrap tipper 4 remains tilted, collecting scrap steel while simultaneously allowing it to fall directly into the scrap hopper 11. This avoids problems such as abnormal speed reduction or stoppage, scrap steel falling into the second transport channel 3, scrap steel accumulating at the scrap tipper 4, and safety hazards for operators entering confined spaces to handle scrap steel. This improves work efficiency and safety.
