Description

Technical Field

[0001] This invention relates to the field of steel production technology, and in particular to a device for measuring the liquid level on the surface of a crystallizer. Background Technology

[0002] As the core equipment in continuous steel casting production, the liquid level inside the crystallizer directly determines the surface quality of the cast billet and the smoothness of the production process. The thickness of the slag layer inside the crystallizer is a key factor in controlling processes such as the addition of protective slag and the casting speed. To accurately obtain these liquid level parameters, the industry commonly uses the wire contact measurement method. This method involves inserting a measuring wire into the molten steel and protective slag medium inside the crystallizer. The temperature difference between the medium creates a characteristic imprint on the wire, which is then measured to determine the thickness of the slag layer.

[0003] However, this method can only measure the thickness of the liquid slag layer at one point. Using the data from one point to represent the thickness of the entire liquid slag layer results in biased and random data that is not accurate enough. Furthermore, the metal wire cannot measure liquid surface fluctuations, the measurement parameters are relatively simple, and the measurement operation is usually performed manually. The working environment around the crystallizer is harsh, with high temperatures, which makes the workers uncomfortable. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a device for measuring the liquid level state on the surface of a crystallizer.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An apparatus for measuring the liquid level on the surface of a crystallizer includes: a frame with a first guide structure; a measuring steel plate that can move up and down relative to the frame and has a second guide structure that cooperates with the first guide structure, wherein the first guide structure and the second guide structure cooperate to guide the up and down movement of the measuring steel plate relative to the frame; a drive assembly mounted on the frame; and a transmission mechanism connected to the drive assembly and the measuring steel plate to transmit power to the measuring steel plate and drive the measuring steel plate to move up and down.

[0006] Furthermore, it also includes an image sensor for acquiring images of the surface of the measuring steel plate aligned with the position of the image sensor.

[0007] Furthermore, the first guide structure is a guide sleeve; the second guide structure is a guide rod that is movably inserted through the guide sleeve; multiple sets of the guide sleeve and the guide rod are provided accordingly.

[0008] Furthermore, the upper end of the guide rod is provided with a threaded shaft, and a limit nut is threadedly connected to the threaded shaft.

[0009] Furthermore, the transmission mechanism includes a first transmission member, a second transmission member, a third transmission member, and a fourth transmission member. The third and fourth transmission members are connected to the measuring steel plate to move up and down synchronously with it. The first transmission member is connected to a drive assembly to obtain power. The first transmission member and the second transmission member are in a transmission engagement so that the continuously moving first transmission member can drive the second transmission member to move intermittently. The measuring steel plate has a measuring state and a continuously moving state. The measuring steel plate in the measuring state is lower than the measuring steel plate in the continuously moving state. In the measuring state, the first transmission member is disengaged from the third transmission member, and the second transmission member is in a transmission engagement with the fourth transmission member to drive the measuring steel plate up and down, thereby enabling the continuously moving first transmission member to drive the measuring steel plate to move up and down intermittently. In the continuously moving state, the second transmission member is disengaged from the fourth transmission member, and the first transmission member is in a transmission engagement with the third transmission member so that the continuously moving first transmission member can drive the measuring steel plate to move up and down continuously.

[0010] Furthermore, a transmission bar is provided at the upper middle part of the measuring steel plate, the third transmission component is a first rack provided on the transmission bar, and the fourth transmission component is a second rack provided on the transmission bar; the first transmission component includes a first gear that drives and cooperates with the first rack, and the second transmission component includes a second gear that drives and cooperates with the second rack.

[0011] Further, the first transmission component includes a centering disk coaxially fixed to the first gear. The outer periphery of the centering disk is smaller than that of the first gear. A shift post is provided on the side of the first gear facing the centering disk, located on the outer periphery of the centering disk. The second transmission component includes a dial coaxially fixed to the second gear. Multiple shift bars are evenly arranged around the outer periphery of the dial. Each shift bar has a strip-shaped opening groove. The dial has an arc groove between adjacent shift bars that matches the contour of the centering disk. The peripheral wall of the centering disk has a notch. The first transmission component has a engaged state and an idle state. In the engaged state, the shift bars are embedded in the notch, and the shift post on the first transmission component is embedded in the strip-shaped opening groove and can drive the second transmission component to rotate. In the idle state, the centering disk is centered and engaged with the arc groove to achieve circumferential limiting of the second transmission component.

[0012] Furthermore, the bottom of the transmission bar is provided with an installation bar, the upper end of the measuring steel plate is fixedly connected to the installation bar by fasteners, and the second guide structure is fixedly installed on the upper end of the installation bar.

[0013] Furthermore, the frame is equipped with a transmission box, and both the first transmission component and the second transmission component are rotatably mounted on the transmission box.

[0014] Furthermore, the frame is provided with a motor mounting plate, and the drive assembly is a motor mounted on the motor mounting plate.

[0015] The present invention has the following beneficial effects: Using a measuring steel plate as the core measuring component, compared to the single-point measurement method using metal wires in existing technologies, the planar measuring steel plate, upon contact with the molten steel and protective slag media within the crystallizer, forms a planar feature imprint covering the measuring surface. This allows for the simultaneous acquisition of thickness data for the liquid slag layer at multiple locations within the measuring surface, avoiding the limitations and randomness of single-point measurement data and significantly improving the accuracy of liquid slag layer thickness measurement results. Furthermore, the planar imprint visually reflects the undulations of the liquid surface within the measuring surface, enabling the simultaneous acquisition of parameters related to liquid surface fluctuations, effectively solving the problem of single measurement parameters in existing technologies. The first guide structure on the frame, in conjunction with the second guide structure of the measuring steel plate, provides stable and precise guidance for the lifting and lowering of the measuring steel plate, limiting its movement trajectory relative to the frame and preventing deviations and swaying during lifting and lowering. The drive assembly stably transmits power to the measuring steel plate through a transmission mechanism, achieving automated driving of the measuring steel plate's lifting and lowering activities. This replaces the manual measurement method in existing technologies, eliminating the need for operators to manually perform measurement actions in the high-temperature and harsh working environment around the crystallizer, effectively improving the operator's experience.

[0016] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0023] Please refer to Figure 1 and Figure 2 The present invention provides a preferred embodiment of an apparatus for measuring the liquid level on the surface of a crystallizer, comprising a frame 100, a measuring steel plate 200, a drive assembly 300, and a transmission mechanism 400.

[0024] The frame 100 is provided with a first guide structure.

[0025] The measuring steel plate 200 can move up and down relative to the frame 100. The measuring steel plate 200 is provided with a second guide structure that cooperates with the first guide mechanism. The first guide mechanism and the second guide structure cooperate to guide the up and down movement of the measuring steel plate 200 relative to the frame 100.

[0026] The drive assembly 300 is mounted on the rack 100.

[0027] The transmission mechanism 400 is connected to the drive assembly 300 mechanism and the measuring steel plate 200 to transmit power to the measuring steel plate 200 and drive the measuring steel plate 200 to move up and down.

[0028] This invention provides a device for measuring the liquid level state on the surface of a crystallizer. A measuring steel plate 200 is used as the core measuring component. Compared to the single-point measurement method using metal wires in existing technologies, the planar measuring steel plate 200 contacts the medium 510 within the crystallizer 500. When the measuring steel plate 200 contacts the molten steel and protective slag medium on the liquid surface, it forms a planar feature imprint covering the measuring surface. This allows for the simultaneous acquisition of thickness data of the liquid slag layer at multiple locations within the measuring surface, avoiding the partiality and randomness of single-point measurement data and significantly improving the accuracy of the liquid slag layer thickness measurement results. Furthermore, the planar imprint visually reflects the undulation state of the liquid surface within the measuring surface, allowing for the simultaneous acquisition of liquid surface fluctuation-related parameters, effectively solving the problem of single measurement parameters in existing technologies. The first guide structure on the frame 100 cooperates with the second guide structure of the measuring steel plate 200 to provide stable and precise guidance for the lifting and lowering of the measuring steel plate 200, limiting the movement trajectory of the measuring steel plate 200 relative to the frame 100 and preventing problems such as offset and swaying during the lifting and lowering process. The drive component 300 transmits power stably to the measuring steel plate 200 through the transmission mechanism 400, realizing the automated drive of the lifting and lowering of the measuring steel plate 200. This replaces the manual measurement method in the existing technology, eliminating the need for staff to manually perform measurement actions in the high-temperature and harsh working environment around the crystallizer, and effectively improving the work experience of the staff.

[0029] In some embodiments of the present invention, an image sensor is also included for acquiring images of the surface of the measuring steel plate 200 aligned with the image sensor. Adding an image sensor enables automated image acquisition of the aligned measuring steel plate 200 surface, replacing manual observation of the surface features, avoiding subjective errors caused by manual observation, and making the acquisition of information such as slag layer thickness and liquid surface fluctuations more objective and accurate. Simultaneously, image acquisition is far more efficient than manual observation, quickly obtaining complete imprint information of the measuring steel plate surface, facilitating subsequent analysis and processing of measurement data, and further improving the automation and efficiency of the overall measurement operation. It is understood that, to avoid the image sensor coming into contact with high temperatures, it will be positioned above the crystallizer, typically aligning and acquiring images of the measuring steel plate at the top of the travel path.

[0030] Reference Figure 2 In some embodiments of the present invention, the first guiding structure is a guide sleeve 110; the second guiding structure is a guide rod 210 movably passing through the guide sleeve 110; multiple sets of guide sleeves 110 and guide rods 210 are correspondingly provided. The sliding fit between the guide sleeve 110 and the guide rod 210 can provide precise linear guidance for the lifting and lowering of the measuring steel plate 200; and the multiple sets of guide sleeves 110 and guide rods 210 correspondingly provide uniform force during the lifting and lowering of the measuring steel plate 200, ensuring that the measuring steel plate always maintains a stable lifting and lowering posture, and reducing measurement errors caused by posture deviations.

[0031] Reference Figure 2 In some embodiments of the present invention, the upper end of the guide rod 210 is provided with a threaded shaft, and a limit nut 211 is threadedly connected to the threaded shaft. By providing a threaded shaft at the upper end of the guide rod 210 and cooperating with the limit nut 211, the position can be adjusted by turning the limit nut along the threaded shaft, thus precisely limiting the descent limit position of the measuring steel plate 200. The limit position can be flexibly adjusted according to different specifications of crystallizers and different production conditions without modifying the main structure of the device, which significantly improves the adaptability of the device to different continuous casting production conditions and also prevents the guide rod 210 from detaching from the guide sleeve 110 and falling off.

[0032] Reference Figure 2In some embodiments of the present invention, the transmission mechanism 400 includes a first transmission member 410, a second transmission member 420, a third transmission member 430, and a fourth transmission member 440. The third transmission member 430 and the fourth transmission member 440 are connected to the measuring steel plate 200 to move synchronously with it. The first transmission member 410 is connected to the drive assembly 300 to obtain power. The first transmission member 410 and the second transmission member 420 are in a transmission engagement such that the continuously moving first transmission member 410 can drive the second transmission member 420 to move intermittently. The measuring steel plate 200 has a measuring state and a continuously moving state; the measuring steel plate 200 in the measuring state is lower than the measuring steel plate 200 in the continuously moving state.

[0033] During measurement, the first transmission component 410 is disengaged from the third transmission component 430, and the second transmission component 420 is engaged with the fourth transmission component 440 to drive the measuring steel plate 200 to rise and fall. This enables the continuously moving first transmission component 410 to drive the measuring steel plate 200 to rise and fall intermittently.

[0034] During continuous lifting and lowering, the second transmission component 420 disengages from the fourth transmission component 440, while the first transmission component 410 engages with the third transmission component 430, enabling the continuously moving first transmission component 410 to drive the measuring steel plate 200 in continuous lifting and lowering. That is, the engagement of the first transmission component 410 with the third transmission component 430 and the engagement of the second transmission component 420 with the fourth transmission component 440 alternate, thereby achieving different operational characteristics at different stages.

[0035] This invention, through the cooperation of the first transmission component 410, the second transmission component 420, the third transmission component 430, and the fourth transmission component 440, enables flexible switching between the measurement state and the continuous lifting state of the measuring steel plate 200. In the measurement state, the measuring steel plate 200 intermittently rises and falls, that is, the measuring steel plate rises a certain distance and then stops for a period of time, enough to complete one imprint formation, then rises a certain distance again and stops for a period of time, thereby forming multiple sets of imprints at different heights on the steel plate surface. This allows the measuring steel plate, which is inserted into the liquid surface, to complete multiple liquid surface contacts and form multiple sets of characteristic imprints, further enriching the measurement data, avoiding the randomness of a single measurement, and improving the comprehensiveness and accuracy of the measurement results. In the continuous lifting state, the measuring steel plate 200 can be driven to rise and fall rapidly. After the measurement is completed, it can be quickly lifted away from the high-temperature liquid surface of the crystallizer, shortening the lifting and lowering time of the measuring steel plate and improving the efficiency of the overall measurement operation.

[0036] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments of the present invention, a transmission bar 220 is provided at the upper middle part of the measuring steel plate 200, a third transmission member 430 is a first rack provided on the transmission bar 220, and a fourth transmission member 440 is a second rack provided on the transmission bar 220. It is understood that the transmission bar 220, the first rack, and the second rack are integral structural components. The first transmission member 410 includes a first gear 411 that engages with the first rack, and the second transmission member 420 includes a second gear 421 that engages with the second rack. It is understood that the transmission between the gear and the rack can be direct meshing or indirect meshing via an intermediate transmission gear. In this embodiment, the second gear 421 and the second rack (fourth transmission member 440) are directly meshed, and the transmission between the first gear 411 and the first rack (third transmission member 430) is achieved through an intermediate gear 450. Disengagement of the first gear 411 from the first rack (third transmission member 430) means that the intermediate gear 450 disengages from the first rack (third transmission member 430). A transmission bar 220 is set in the middle of the measuring steel plate 200, and the third transmission component is set as the first rack and the fourth transmission component is set as the second rack. The first transmission component is set as the first gear 411 and the second transmission component is set as the second gear 421. The meshing transmission between the gear and the rack makes the power transmission smoother and more precise, and can accurately control the lifting stroke and speed of the measuring steel plate, ensuring that the displacement of each lifting is consistent during intermittent lifting, and ensuring the consistency of multiple measurements.

[0037] Reference Figures 5 to 8 In a further embodiment of the present invention, the first transmission member 410 includes a centering disk 412 coaxially fixed with the first gear 411. The outer periphery of the centering disk 412 is smaller than that of the first gear 411. A shift post 413 located on the outer periphery of the centering disk 412 is provided on the side of the first gear 411 facing the centering disk 412. The second transmission member 420 includes a dial 422 coaxially fixed with the second gear 421. A plurality of shift bars 423 are evenly arranged around the outer periphery of the dial 422. The shift bars 423 are provided with strip-shaped opening slots 424. The dial 422 is positioned between adjacent shift bars 423. The first transmission member 410 has an arc groove 425 that matches the contour of the centering disk 412, and a notch 414 is provided on the peripheral wall of the centering disk 412. The first transmission member 410 has a engaged state and an idle state. In the engaged state, the lever 423 is inserted into the notch 414, and the lever 413 on the first transmission member 410 is inserted into the strip-shaped opening groove 424, which can drive the second transmission member 420 to rotate. At this time, the first transmission member 410 rotates, and because the lever 413 is inserted into the strip-shaped opening groove 424, it can drive the second transmission member 420 to rotate until the lever 413 disengages from the strip-shaped opening groove 424, and then enters the idle state. Figure 5 and Figure 6As shown, at this time, the shift post 413 is about to disengage from the strip-shaped opening slot 424, and the centering disk 412 and the arc groove 425 are centering and engaged, which is at the transition position between the two states. It can also be seen that at this time, it is also at the transition position between the measurement state and the continuous lifting state. At this time, the lowermost tooth of the second rack (fourth transmission component 440) is driven upward by the second gear 421 and is about to disengage from the transmission of the second gear 421; while the uppermost tooth of the first rack (third transmission component 430) has entered the range of motion of the first gear 411 and is about to be driven upward by the first gear 411. Of course, at this time, there is still a certain gap between the uppermost tooth of the first rack (third transmission component 430) and the outer tooth of the first gear 411 to provide a certain clearance margin, so that some clearance redundancy is left when the two states alternate, so as to avoid structural interference or jamming when the state is switched due to the design being too compact. In addition, from the moment the pusher 413 enters the strip-shaped opening groove 424 until it leaves the strip-shaped opening groove 424, although the rotational speed of the pusher 413 remains constant, the rotational speed of the driven second transmission component 420 is indeed constantly changing. The rotational speed of the driven second transmission component 420 gradually increases to its peak and then gradually decreases to zero, so that the speed of the measuring steel plate in the measurement state changes gradually during the rising process. This can effectively avoid the additional fluctuations in the liquid surface caused by the instantaneous high-speed start and stop of the steel plate, which would affect the measurement or damage the liquid surface state.

[0038] In the idling state, the centering disk 412 and the arc groove 425 are engaged in centering to achieve circumferential limiting of the second transmission component 420. At this time, since the shift pin 413 is disengaged from the strip-shaped opening groove 424, the rotation of the first transmission component 410 will not drive the rotation of the second transmission component 420. In addition, the centering disk 412 and the arc groove 425 further restrict the rotational freedom of the second transmission component 420. Only when the shift pin 413 re-enters the strip-shaped opening groove 424 can the second transmission component 420 be rotated again. By intermittently rotating the second transmission component 420, the measuring steel plate 200 can be intermittently raised and lowered. Through the mechanical structure of centering disc 412, shift pin 413, notch 414, shift plate 422, shift bar 423, strip-shaped opening groove 424, and arc groove 425, the switching between two states—engaged and idle—is achieved. In the engaged state, the shift pin 413, embedded in the strip-shaped opening groove 424, can precisely drive the second transmission component to rotate, ensuring reliable power transmission. In the idle state, the centering engagement of centering disc 412 and arc groove 425 can reliably limit the circumferential movement of the second transmission component, preventing it from rotating due to its own weight or equipment vibration, ensuring accurate meshing position and no jamming or misalignment when engaging again. This purely mechanical engagement method eliminates the need for additional electrical control components, enabling the intermittent movement of the second transmission component 420 while the first transmission component 410 is continuously moving. This reduces the electrical control complexity and failure probability of the device, significantly improving the stability and reliability of the device's operation. Typically, the drive component 300 is a motor. The output shaft of the motor is connected to the first transmission component 410 through a reduction mechanism, which drives the first transmission component 410 to rotate, thereby controlling the lifting and lowering of the measuring steel plate.

[0039] Of course, in other embodiments of the present invention, other methods can also be used to achieve intermittent and continuous lifting and lowering of the measuring steel plate, for example... Figure 9 As shown, the drive assembly 300 is a motor, and the transmission mechanism 400 includes an output gear 460 and a transmission rack 461 disposed on the upper end of the measuring steel plate. The output shaft of the motor is connected to the output gear 460, and the output gear is connected to the transmission rack, driving the measuring steel plate to rise and fall. Intermittent starting and stopping of the motor allows for intermittent rising and falling of the measuring steel plate, while continuous operation of the motor allows for continuous rising and falling of the measuring steel plate. Of course, to achieve precise control of the measuring state and the continuous rising and falling state, such as... Figure 10 As shown, the drive assembly 300 can be configured with two motors, compared to Figure 5In the structure shown in this embodiment, the first transmission member 410 and the third transmission member 430 have no transmission relationship. The first transmission member 410 only has intermittent transmission cooperation with the second transmission member 420. The transmission mechanism 400 also includes a drive gear 470, the second transmission member 420 and the fourth transmission member 440. One motor is connected to the first transmission member 410 to drive and control the rotation of the first transmission member 410, and another motor is connected to the drive gear 470 to drive the rotation of the drive gear 470. The drive gear 470 has transmission cooperation with the third transmission member 430 (first rack). In this way, the intermittent lifting and continuous lifting of the measuring steel plate can be switched by controlling the alternating start of the two motors. When the other motor stops working, the conveying shaft is in a state where it can rotate freely, which will not cause the structure to jam.

[0040] Reference Figure 2 In some embodiments of the present invention, the bottom of the transmission bar 220 is provided with an installation bar 221, and the upper end of the measuring steel plate 200 is fixedly connected to the installation bar 221 by fasteners. The second guide structure is fixedly disposed on the upper end of the installation bar 221. The installation bar 221 increases the contact area between the transmission bar and the measuring steel plate, making the connection more secure and avoiding the problem of loosening of the connection under long-term lifting and high-temperature conditions. The fastener connection method facilitates the disassembly, replacement and maintenance of the measuring steel plate 200. Since the measuring steel plate is easily worn due to long-term contact with high-temperature molten steel and protective slag, a new measuring steel plate can be quickly replaced without affecting the overall efficiency of the device. The installation bar 221 is thicker, which also facilitates the setting of the second guide structure. It can be understood that the installation bar 221 can be provided with an opening groove facing downward for the measuring steel plate to be embedded, making installation more convenient and positioning more accurate.

The transmission box 120 is provided on the frame 100 and the first transmission component 410 and the second transmission component 420 are rotatably mounted therein. The transmission box 120 can provide a certain degree of protection for the core transmission components.

The motor mounting plate 130 is provided on the frame 100, and the drive assembly 300 is a motor mounted on it. The motor serves as a power source, providing stable and controllable power output.
