More specifically, it relates to a tilting prevention device for the piston of a converter gas holder, and the present invention also relates to a control method for the tilting prevention device of the piston of a converter gas holder. Background Art
[0002] The purpose of a converter gas holder is to recover the converter gas generated during the blowing of converters in a steel mill and provide it for effective utilization by users and self-provided power plants. A converter gas holder is a device for recovering and storing converter gas. Generally, a piston is arranged inside it. While being used for measurement, its main purpose is to compress the converter gas. Therefore, the stable operation of the piston in the converter gas is extremely important. At present, due to the instability of the gas inside the converter gas holder, it is easy for the piston to tilt to one end, thus affecting the use of the converter gas holder. And the staff cannot know the situation of the piston inside the converter gas holder in time, which prompts working in an unsafe state and is prone to safety accidents. Therefore, it is necessary to conduct safety detection on the internal state of the converter gas holder to ensure its safe operation.
[0003] In the prior art, there is a technology with the name of "a piston structure of a converter gas holder" and a publication number of "CN217464050U". This technology discloses a piston structure of a converter gas holder, including a spherical shell. The side surface of the spherical shell is fixedly connected with a piston ring beam. The upper surface of the piston ring beam is fixedly connected with a piston fence. The side surface of the piston fence is fixedly connected with a rubber pad. The upper surface of the spherical shell is fixedly connected with scale cylinders. There are four scale cylinders in total. Water is arranged inside the scale cylinders. The four scale cylinders are communicated with each other. A tension wire is fixedly connected inside the piston fence. One end of the tension wire far away from the piston fence is fixedly connected with a lifting wheel. In this utility model, by setting the scale cylinders and the lifting wheel, it is convenient to detect and maintain the balance of the piston, so as to realize automatic adjustment and not form a stuck state during rising, thus ensuring the storage effect. By setting the telescopic rod and the spring, the elastic force of the spring can be effectively utilized to provide assistance in the initial stage of air intake and exhaust, ensuring the smoothness and speed inside. However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:
[0006] The present invention relates to an anti-tipping device for the piston of a converter gas holder. Inside the converter gas holder body, there is a piston member. Arc-shaped frames are respectively arranged on the left and right sides of the converter gas holder body.

A secondary adjustment and stabilization mechanism is provided between the internal straight cylinder and the balance detection mechanism. One first magnet block is respectively arranged on each side of the piston member, and each first magnet block is located directly below a secondary adjustment and stabilization mechanism.
[0007] Two balance detection mechanisms are provided. Each balance detection mechanism includes a first magnet block, an internal straight plate, a balance plate, a connecting rod, a second magnet block, a moving plate, and a displacement sensor. One end of each second magnet block close to the corresponding first magnet block has a repulsive structure.
[0008] The inner bottom end of the connecting through frame is fixedly connected with an internal straight plate. The outer end of the internal straight plate is movably connected to the balance plate. One connecting rod is connected to the lower end of each end of the balance plate. The lower end of the connecting rod located inside the internal straight cylinder is movably connected to the second magnet block. The lower end of the connecting rod located inside the arc-shaped frame is movably connected to the moving plate. A displacement sensor is installed at the lower end of the moving plate.
[0009] Two tipping adjustment mechanisms are provided. Each tipping adjustment mechanism includes a first cylinder installed on the inner bottom end of the arc-shaped frame. The upper end of the first cylinder is connected to an electric suction cup. The electric suction cup is located below the moving plate.
[0010] Two secondary adjustment and stabilization mechanisms are provided. Each secondary adjustment and stabilization mechanism includes a second cylinder. The second cylinder is installed on the inner wall of the internal straight cylinder. Circular holes are drilled at the inner bottom end of the internal straight cylinder. The output end of the second cylinder passes through the circular hole and extends to its lower side. The output end of the second cylinder is fixedly connected with a storage frame. A magnetic fluid is provided inside the storage frame.
[0011] Both the first magnet block and the second magnet block are made of single-sided magnet material. The upper end of the first magnet block is the magnetic end, and the lower end of the second magnet block is the magnetic end.
[0012] A rectangular through groove is drilled inside the balance plate. Both the front and rear ends of the internal straight plate are rotatably connected to the inner wall of the rectangular through groove through rotating shafts.
[0013] Sliding wheels are respectively installed on the left and right ends of the second magnet block. The outer end of each sliding wheel is in sliding contact with the inner wall of the internal straight cylinder.
[0014] The displacement sensor is located on the side of the electric suction cup; a sealing ring is fixedly connected to the inner wall of the circular hole, and the inner wall of the sealing ring is in close contact with the outer end of the output end of the second cylinder; the outer end of the movable plate is in contact with the inner wall of the arc frame, and semicircular blocks are respectively arranged on the upper part of the second magnet block and the middle part of the movable plate, and each semicircular block is rotatably connected to a corresponding connecting rod.
[0015] The present invention also relates to a control method for a converter gas tank piston anti-dumping device which has simple steps and can effectively assist the piston to accurately return to a balanced state during the resetting process when the piston tips over, thereby preventing the converter gas tank body from operating in an unsafe state, reducing the occurrence of safety accidents, and improving safety.
[0016] The control steps of the control method of the converter gas tank piston anti-dumping device are as follows:
[0017] S1. The gas inside the converter gas cabinet is unstable, causing the piston to tilt to one end and the other end to tilt upward, driving the first magnet block at the tilted end to also tilt upward and approach the corresponding second magnet block, breaking the magnetic balance between the two;
[0018] S2. The second magnet block moves upward under the repulsive force of the first magnet block, and the balance plate is squeezed to tilt inside the arc frame through the connecting rod, pushing the moving plate and the displacement sensor to move downward, and the displacement sensor detects that the piston is in a dumping state according to the displacement;
[0019] S3. When the displacement sensor feeds back the detection information to the first cylinder, the first cylinder corresponding to the descending moving plate starts working, pushing the electric suction cup to move upward until it contacts and adsorbs the lower end of the moving plate, and then continues to push the electric suction cup upward, squeezing the moving plate to move upward, driving the balance plate to flip, and start to recover from the tilted state to the balanced state, thereby squeezing the upturned second magnet block to move downward for reset;
[0020] S4. The reset movement breaks the balance between the first magnet block and the second magnet block after the tilting, and uses the repulsive force to squeeze the upturned first magnet block downward, driving the piston part to gradually return to a balanced state from a tilted state. After detecting that the piston part is in a tilted state, it can automatically perform leveling to restore the piston part to a balanced state, thereby facilitating the safe operation of the piston part and the converter gas tank.
[0021] The technical solution of the present invention is adopted, and the working principle and beneficial effects are as follows:
[0022] The tilting prevention device for the piston of a converter gas holder and its control method according to the present invention can monitor the movement state of the piston in the converter gas holder in real time. When the piston (piston element) tilts to one side, it can be detected in time and intervened in time, so that the piston element can quickly return to balance, that is, return to normal operation. During the operation of the piston element, when the piston element tilts to one end due to unstable gas, that is, the magnetic balance relationship between the first magnet block and the second magnet block in the balance detection mechanism is broken, the upward-tilting first magnet block repels the second magnet block to move upward, driving the balance plate to tilt inward the arc-shaped frame, pushing the moving plate and the displacement sensor downward, so as to detect that the piston element is in a tilted state. The displacement sensor gives an alarm and at the same time feeds back to the tilting leveling mechanism and the auxiliary leveling and stabilizing mechanism, causing the tilting leveling mechanism to act. The moving plate is pushed upward to reset by the first air cylinder. By virtue of the repulsive relationship between the first magnet block and the second magnet block, the piston element is gradually squeezed to reset. And the auxiliary leveling and stabilizing mechanism respectively pushes and pulls the upward-tilting and downward-tilting end faces through the second air cylinder, assisting the piston element to accurately return to the balanced state during the reset process, avoiding the converter gas holder body from working in an unsafe state, reducing the occurrence of safety accidents, and improving safety.

[0033] As shown in the attached Figure 1 - As shown in the attached Figure 7As shown in the figure, the present invention is a tilting prevention device for the piston of a converter gas cabinet. A ventilation cap 2 is installed at the upper end of the converter gas cabinet body 1. A piston member 3 is arranged inside the converter gas cabinet body 1. Arc-shaped frames 4 are respectively arranged on the left and right sides of the converter gas cabinet body 1. The arc-shaped frames 4 are communicated with the inside of the converter gas cabinet body 1 through connecting through frames 6. One end of the connecting through frame 6 located inside the converter gas cabinet body 1 is communicated with an internal straight cylinder 5. The internal straight cylinder 5 is located above the piston member 3. A balance detection mechanism 7 is arranged in the arc-shaped frames 4, the connecting through frames 6 and the internal straight cylinder 5. A tilting adjustment mechanism 8 is arranged inside the arc-shaped frames 4. An auxiliary adjustment and stabilization mechanism 9 is arranged between the internal straight cylinder 5 and the balance detection mechanism 7. A first magnet block 701 is arranged on each side of the piston member 3, and each first magnet block 701 is located directly below an auxiliary adjustment and stabilization mechanism 9. The above structure proposes an improved technical solution for the problems existing in the prior art. The device of the present invention monitors the movement state of the piston member inside the converter gas cabinet body 1 in real time. When the piston member (piston) tilts to one side, it can be detected in time and intervened in time, so that the piston member quickly returns to balance, that is, returns to normal operation. During the operation of the piston member, when the piston member tilts to one end due to unstable gas, that is, the magnetic balance relationship between the first magnet block and the second magnet block in the balance detection mechanism is broken, the upturned first magnet block repels the second magnet block to move upward, driving the balance plate to tilt inward the arc-shaped frame, pushing the moving plate and the displacement sensor to move downward, so as to detect that the piston member is in a tilted state, give an alarm, and at the same time feedback to the tilting adjustment mechanism and the auxiliary adjustment and stabilization mechanism, so that the tilting adjustment mechanism pushes the moving plate upward to reset through the first cylinder, and by means of the repulsive relationship between the first magnet block and the second magnet block, the piston member is gradually squeezed to reset, and the auxiliary adjustment and stabilization mechanism respectively pushes and pulls the upturned and downturned end faces through the second cylinder, assisting the piston member to accurately return to the balanced state during the reset process, avoiding the converter gas cabinet body from working in an unsafe state, reducing the occurrence of safety accidents, and improving safety. The tilting prevention device for the piston of the converter gas cabinet and its control method of the present invention can effectively assist the piston member to accurately return to the balanced state during the reset process when the piston member tilts, avoid the converter gas cabinet body from working in an unsafe state, reduce the occurrence of safety accidents, and improve the operation safety.
[0034] There are two balance detection mechanisms 7. Each balance detection mechanism 7 includes a first magnet block 701, an inner straight plate 702, a balance plate 703, a connecting rod 704, a second magnet block 705, a moving plate 706, and a displacement sensor 707. One end of each second magnet block 705 close to the corresponding first magnet block 701 is a repulsive structure. The inner bottom end of the connecting through frame 6 is fixedly connected with an inner straight plate 702. The outer end of the inner straight plate 702 is movably connected with a balance plate 703. One connecting rod 704 is connected to the lower end of each end of the balance plate 703. The lower end of the connecting rod 704 located in the inner straight cylinder 5 is movably connected with the second magnet block 705. The lower end of the connecting rod 704 located inside the arc-shaped frame 4 is movably connected with the moving plate 706. The displacement sensor 707 is installed at the lower end of the moving plate 706. With the above structure, the specific structure of the balance detection mechanism 7 and its specific layout in the converter gas cabinet body 1 are improved. During the use of the converter gas cabinet of the present invention, when the piston member 3 topples to one end due to unstable gas, the magnetic balance relationship between the corresponding first magnet block 701 and the second magnet block 705 in the balance detection mechanism 7 is broken, causing the upward-tilting first magnet block 701 to repel the second magnet block 705 to move upward, driving the balance plate 703 to tilt inward the arc-shaped frame 4, pushing the moving plate 706 and the displacement sensor 707 to move downward, thereby detecting that the piston member 3 is in a toppled state. The displacement sensor alarms and simultaneously feeds back to the tilting leveling mechanism 8 and the auxiliary leveling and stabilizing mechanism 9, so that the tilting leveling mechanism 8 pushes the moving plate 706 upward to reset through the first cylinder 801. By virtue of the repulsive relationship between the first magnet block 701 and the second magnet block 705, the piston member 3 is gradually squeezed to reset. And the auxiliary leveling and stabilizing mechanism 9 respectively pushes and pulls the upward-tilting and downward-tilting end faces through the second cylinder 901, assisting the piston member 3 to accurately return to the balanced state during the reset process, avoiding the converter gas cabinet body 1 from working in an unsafe state, reducing the occurrence of safety accidents, and improving the safety of the operation.
[0035] There are two tilting leveling mechanisms 8. Each tilting leveling mechanism 8 includes a first cylinder 801 installed on the inner bottom end of the arc-shaped frame 4. The upper end of the first cylinder 801 is connected with an electric suction cup 802. The electric suction cup 802 is located below the moving plate 706. With the above structure, the tilting leveling mechanism 8 pushes the moving plate 706 upward to reset through the first cylinder 801. By virtue of the repulsive relationship between the first magnet block 701 and the second magnet block 705, the piston member 3 is gradually squeezed to reset. And the auxiliary leveling and stabilizing mechanism 9 respectively pushes and pulls the upward-tilting and downward-tilting end faces through the second cylinder 901, assisting the piston member 3 to accurately return to the balanced state during the reset process.
[0036] The described auxiliary adjustment and stabilization mechanism 9 includes two. Each auxiliary adjustment and stabilization mechanism 9 includes a second cylinder 901, and the second cylinder 901 is installed on the inner wall of the built-in straight cylinder 5. Circular holes 904 are drilled at the bottom end inside the built-in straight cylinder 5. The output end of the second cylinder 901 passes through the circular hole 904 and extends to its lower side. The output end of the second cylinder 901 is fixedly connected with a storage frame 902, and a magnetorheological fluid 903 is arranged inside the storage frame 902. The above structure improves the structural design of the auxiliary adjustment and stabilization mechanism 9. The auxiliary adjustment and stabilization mechanism 9 drives the storage frame 902 and the magnetorheological fluid 903 to move downward through the second cylinder 901, which are respectively in contact with the upturned and downturned end faces. By virtue of the magnetic attraction relationship between the first magnet block 701 and the magnetorheological fluid 903, the storage frame 902 is tightly adsorbed on the first magnet block 701. Then, for the upturned end face of the piston member 3, the corresponding second cylinder 901 pushes it downward through the storage frame 902. At the same time, for the downturned end face of the piston member 3, the corresponding second cylinder 901 pulls it upward through the storage frame 902 to perform the auxiliary adjustment of pushing down and pulling up, enabling the piston member 3 to accurately return to the balanced position. Moreover, after the piston member 3 returns to the balanced state driven by the second cylinder 901, the storage frame 902 can limit its position, ensuring its balance in the unstable gas state, not prone to tipping over, being safe and stable. Thus, the converter gas cabinet body 1 can work in a safe balanced state, avoiding working in an unsafe state, reducing the occurrence of safety accidents, and improving safety.
[0037] Both the described first magnet block 701 and the second magnet block 705 are made of single-sided magnet materials. The upper end of the first magnet block 701 is the magnetic end, and the lower end of the second magnet block 705 is the magnetic end.
[0038] A rectangular through groove 7031 is drilled inside the described balance plate 703. Both the front and rear ends of the built-in straight plate 702 are rotatably connected to the inner wall of the rectangular through groove 7031 through rotating shafts 7032. The above structure, as shown in the attached Figure 6 figure, a rectangular through groove 7031 is drilled inside the balance plate 703. Both the front and rear ends of the built-in straight plate 702 are rotatably connected to the inner wall of the rectangular through groove 7031 through bearings and rotating shafts. During the use of the device of the present invention, through the rotational connection between the outer end of the built-in straight plate 702 and the inner wall of the rectangular through groove 7031, the balance plate 703 deflects and adjusts by means of the rotational relationship.
[0039] The left and right end portions of the second magnet block 705 are respectively provided with sliding wheels 7051, and the outer ends of each sliding wheel 7051 are respectively in sliding contact with the inner wall of the built-in straight cylinder 5. With the above structure, sliding wheels 7051 are installed at both the left and right ends of the second magnet block 705, and the outer ends of the sliding wheels 7051 are both slidably connected to the inner wall of the built-in straight cylinder 5. Through the arrangement of the sliding wheels 7051, the second magnet block 705 can maintain stable movement during the up and down movement process, is not prone to deviation, and improves stability.
[0040] The displacement sensor 707 is located at the side position of the electric suction cup 802; a sealing ring is fixedly connected to the inner wall of the round hole 904, and the inner wall of the sealing ring is in close contact with the outer end of the output end of the second cylinder 901; the outer end of the moving plate 706 is in contact with the inner wall of the arc-shaped frame 4, and semi-circular blocks are respectively arranged on the upper part of the second magnet block 705 and the upper part of the moving plate 706, and each semi-circular block is rotatably connected to a corresponding connecting rod 704. Through the arrangement of the sealing ring, it is not easy for the gas in the converter gas cabinet 1 to enter the built-in straight cylinder 5 through the gap between the round hole 904 and the output end of the second cylinder 901, improving the sealing performance. The arrangement of the semi-circular blocks facilitates the connection of the corresponding components to the corresponding connecting rods 704.
[0041] The present invention also relates to a control method for a converter gas cabinet piston anti-tipping device, which has simple steps, can effectively assist the piston part to accurately return to the balanced state during the reset process when the piston part is tilted, avoid the converter gas cabinet from working in an unsafe state, reduce the occurrence of safety accidents, and improve safety.
[0042] The control steps of the control method for the converter gas cabinet piston anti-tipping device are as follows:
[0043] S1. The gas inside the converter gas cabinet 1 is unstable, causing the piston member 3 to tilt toward one end and tilt upward at the other end, driving the first magnet block 701 at the tilted end to also tilt upward and approach the corresponding second magnet block 705, breaking the magnetic balance relationship between the two; S2. The second magnet block 705 moves upward under the repulsive force of the first magnet block 701, and squeezes the balance plate 703 to tilt toward the inside of the arc frame 4 through the connecting rod 704, pushing the moving plate 706 and the displacement sensor 707 to move downward. The displacement sensor 707 detects that the piston member 3 is in a tilted state based on the displacement; S3. When the displacement sensor 707 feeds back the detection information to the first cylinder 801, the first cylinder 801 corresponding to the descending moving plate 706 works, pushing the electric The movable suction cup 802 moves upward until it contacts and adsorbs with the lower end of the movable plate 706, and then continues to push the electric suction cup 802 upward, squeezing the movable plate 706 upward, driving the balance plate 703 to flip, and starting to recover from the tilted state to the balanced state, thereby squeezing the upturned second magnet block 705 to move downward for resetting; S4. The resetting movement breaks the balance relationship between the tilted first magnet block 701 and the second magnet block 705, and squeezes the upturned first magnet block 701 downward with the help of repulsive force, driving the piston member 3 to gradually recover from the tilted state to the balanced state. After detecting that the piston member 3 is in the tilted state, it can automatically perform leveling to restore the piston member 3 to the balanced state, which is convenient for the safe operation of the piston member 3 and the converter gas tank.
[0044] Compared with the prior art, the advantages of the present invention are:
[0045] (1) In the present invention, when the piston part tilts toward one end due to gas instability, the magnetic balance relationship between the corresponding first magnet block and the second magnet block in the balance detection mechanism is broken, so that the upward-curved first magnet block repels the second magnet block to move upward, driving the balance plate to tilt toward the inside of the arc frame, pushing the movable plate and the displacement sensor to move downward, thereby detecting that the piston part is in a tilting state, giving an alarm, and at the same time feeding back to the tilting leveling mechanism and the auxiliary adjustment and stabilization mechanism, so that the tilting leveling mechanism pushes the movable plate upward to reset through the first cylinder, and with the help of the repulsive relationship between the first magnet block and the second magnet block, the piston part is squeezed to reset gradually, and the auxiliary adjustment and stabilization mechanism pushes and pulls the upward and downward-curved end faces through the second cylinder, respectively, so that the auxiliary piston part can accurately return to a balanced state during the reset process, thereby avoiding the converter gas cabinet from working in an unsafe state, reducing the occurrence of safety accidents, and improving safety.
[0046] (2) In the present invention, the gas inside the converter gas cabinet is unstable, causing the piston to tilt toward one end and tilt upward at the other end, driving the first magnet block to tilt upward and approach the second magnet block, breaking the magnetic balance relationship between the two, causing the second magnet block to move upward under the action of repulsion, and squeeze the balance plate through the connecting rod to tilt toward the inside of the arc frame, pushing the moving plate and the displacement sensor to move downward. The displacement sensor detects that the piston is in a tilting state based on the displacement, and can detect it in time when the piston tilts, ensuring the real-time effectiveness and accuracy of the detection. Then, the tilting distance of the piston is detected based on the displacement, and feedback is given to the tilting leveling mechanism and the auxiliary stabilization mechanism for adjustment, so that the piston returns to a balanced state.
[0047] (3) In the present invention, when the displacement sensor feeds back the detection information to the first cylinder, the first cylinder corresponding to the descending movable plate is operated to push the electric suction cup to move upward until it contacts and adsorbs with the lower end of the movable plate, and then continues to push the electric suction cup to move upward, squeezing the movable plate to move upward, driving the balance plate to move upward, and recovering from the tilted state to the balanced state, thereby squeezing the upturned second magnet block to move downward for resetting, breaking the balance relationship between the tilted first magnet block and the second magnet block, squeezing the upturned first magnet block downward with the help of repulsive force, and driving the piston member to gradually recover from the tilted state to the balanced state, thereby achieving automatic and timely leveling after detecting that the piston member is in a tilted state, so that the piston member is restored to a balanced state, ensuring that the piston member can work in a safe state.
[0048] (4) In the present invention, during the leveling process of the piston member driven by the first cylinder to tilt and level the mechanism, there may be a certain distance deviation between the position of the piston member and the equilibrium position. The auxiliary adjustment and stabilization mechanism drives the storage frame and the magnetic fluid to move downward through the second cylinder, respectively contacting the upturned and downturned end faces, and by means of the magnetic attraction relationship between the first magnet block and the magnetic fluid, the storage frame is tightly adsorbed on the first magnet block. Then, for the upturned end face of the piston member, the corresponding second cylinder pushes it to move downward through the storage frame. At the same time, for the downturned end face of the piston member, the corresponding second cylinder pulls it to move upward through the storage frame, and auxiliary adjustments of pushing down and pulling up are performed, so that the piston member can accurately return to the equilibrium position. Moreover, after the piston member returns to the equilibrium state, the second cylinder drives the storage frame to limit it, so that it can ensure balance in the unstable gas state, not easy to tip over, safe and stable, so that the converter gas cabinet can work in a safe balanced state, avoid the converter gas cabinet from working in an unsafe state, reduce the occurrence of safety accidents, and improve safety.

6. The control method of the tilting prevention device for the converter gas cabinet piston according to any one of claims 1 to 5, characterized in that: The control steps of the control method of the converter gas tank piston anti-dumping device are as follows: S1. The gas inside the converter gas cabinet (1) is unstable, causing the piston member (3) to tilt toward one end and tilt upward at the other end, driving the first magnet block (701) at the tilted end to also tilt upward and approach the corresponding second magnet block (705), thereby breaking the magnetic balance between the two; S2. The second magnet block (705) moves upward under the repulsive force of the first magnet block (701), and squeezes the balance plate (703) through the connecting rod (704) to tilt toward the inside of the arc frame (4), pushing the moving plate (706) and the displacement sensor (707) to move downward. The displacement sensor (707) detects that the piston member (3) is in a tilted state according to the displacement; S3. When the displacement sensor (707) feeds back the detection information to the first cylinder (801), the first cylinder (801) corresponding to the descending movable plate (706) starts to work, pushing the electric suction cup (802) to move upward until it contacts and adsorbs the lower end of the movable plate (706), and then continues to push the electric suction cup (802) to move upward, squeezing the movable plate (706) to move upward, driving the balance plate (703) to flip, and start to recover from the tilted state to the balanced state, thereby squeezing the upturned second magnet block (705) to move downward for reset; S4. The restoring movement breaks the equilibrium relationship between the tilted first magnet block (701) and the second magnet block (705), and uses the repulsive force to squeeze the upturned first magnet block (701) to move downward, thereby driving the piston member (3) to gradually return from the tilted state to the balanced state. After detecting that the piston member (3) is in the tilted state, it can automatically perform leveling to restore the piston member (3) to the balanced state, thereby facilitating the safe operation of the piston member (3) and the converter gas tank.
