Description

Technical Field

[0001] This invention relates to the field of sintering machine technology, and in particular to an automatic adjustment device for arching of a sintering machine trolley and a belt sintering machine. Background Technology

[0002] The sintering machine plays a crucial role as one of the raw material supply devices for blast furnaces. The sintering machine trolley is primarily responsible for loading, igniting, sintering, and discharging sintered ore at the tail end along the track. The belt sintering machine is a key piece of equipment in the sintering process. The entire operation is powered by the continuous rotation of star wheels, which drive the trolley in a cyclical motion. The head star wheel is powered and acts as the driving wheel, while the tail star wheel is unpowered and acts as the driven wheel. The sintering machine trolley consists of two sections: the upper sintering section and the lower return section. The trolleys are not interconnected; they are propelled by mutual compression. To accommodate the thermal deformation and elongation of the sintering machine trolley during operation (where the average temperature can reach over 100℃), the tail star wheel can move back and forth within a certain range (approximately 150mm at the head and approximately 250mm at the tail). Because the head star wheel is fixed and the tail star wheel is movable, the trolley suspended on the tail star wheel exerts a backward pulling force on it. Therefore, the tail star wheel needs to be balanced to ensure the ring-shaped structure of the head and tail star wheels. The upper sintering section trolley is driven by the head star wheel, and the lower return stroke is driven by the weight of the trolley itself, in addition to the driving force of the head star wheel.

[0003] During operation, belt sintering machines commonly experience bridging on the return trip of the sintering machine trolley. The main cause of bridging is the force exerted on the trolley by the tail star wheel and the mutual squeezing force between the trolleys as the trolley enters the horizontal return path from the tail curve. When the trolley bridging occurs, wheel wear on the track is accelerated, and the impact on the track during the trolley's descent shortens the equipment's lifespan and, in severe cases, affects the normal operation of the sintering machine. Figure 1 As shown, when the trolley exits the return path from the tail end along the tail curve and passes the star wheel toothed plate, the rear wheels of the trolley rise and do not contact the track. The arching height varies from 5 to 40 mm. When the arching trolley reaches the head of the sintering machine, due to the action of the head star wheel, the rear wheels of the arching trolley will gradually slide down or fall instantly, generating an impact. This causes wear on the trolley track and the end of the trolley body, shortening the service life of the equipment and increasing maintenance costs. If the arching amount is relatively small (<10 mm), the damage to the equipment is minor, and normal production is allowed without intervention; however, if the arching amount is large (≥10 mm), the damage to the equipment (wheels, bearings, tracks, etc.) is significant, and timely adjustment measures are required.

[0004] Currently, some solutions exist for the arching problem of sintering machine trolleys, but there is no universally accepted technology or device that can completely solve the arching issue. The arching condition of the sintering machine changes with factors such as time and production load. Existing technologies typically involve installing an elastic pressing device at the tail of the sintering machine or a pressure roller device on the trolley track. When workers observe severe arching, they activate the elastic pressing device or pressure roller device to eliminate the arching. However, the height of the arching is measured manually by the naked eye or by workers using tools, lacking a scientific quantitative method. This results in delays in processing and adjustment, and the sintering machine trolley operates with faults for extended periods, making real-time monitoring and adjustment impossible.

[0005] In view of this, it is necessary to propose an automatic adjustment device for arching of the sintering machine trolley and a belt sintering machine to solve or at least alleviate the above-mentioned defects. Summary of the Invention

[0040] Please see the appendix Figure 1-10An embodiment of the present invention provides an automatic adjustment device for bridging of a sintering machine trolley, comprising a ranging component 10, an image recognition component 20, an electrical control device (not shown), and a bridging adjustment component 30 disposed at the tail star wheel 450 of the sintering machine 40. First, it should be noted that currently, there is no universally accepted technology or device to completely solve or eliminate the bridging problem commonly found in sintering machine trolleys 420. Currently, bridging of the sintering machine trolley 420 is addressed retrospectively. Adjustments are made only after severe bridging has occurred, relying on visual inspection. This approach cannot provide timely and rapid judgment or response, increasing the time the sintering machine trolley 420 operates with the problem. Furthermore, the height of the bridging is measured visually or manually using tools, lacking scientific quantification methods. This application achieves scientific and quantitative monitoring of the arching amount of the sintering machine trolley 420 by setting up a ranging component 10, an image recognition component 20, and an arching adjustment component 30 in cooperation. The electronic control device obtains the arching amount information obtained by the ranging component 10 and the image recognition component, and activates the arching adjustment component 30 in a targeted and timely manner based on the arching amount information. It can make timely adjustment measures when the arching amount exceeds the set value, thereby achieving the purpose of accurate monitoring and adjustment.

[0041] Specifically, the ranging component 10 is positioned above the return track 410 of the sintering machine 40. The ranging end of the ranging component 10 has a first preset distance from the top of the wheel of the sintering machine trolley 420, and a second preset distance from the measuring end of the ranging component 10 to the axle 452 of the tail star wheel. The ranging component 10 is fixedly connected to the frame 430 of the sintering machine and is used to measure the distance between itself and the top of the wheel of the sintering machine trolley 420. The ranging component 10, positioned above the return track 410, determines whether the sintering machine trolley 420 has exceeded the arching limit by monitoring the distance between itself and the top of the wheel of the sintering machine trolley 420. The first preset distance can be set according to actual needs to ensure high-precision acquisition of the distance between the top of the wheel of the sintering machine trolley 420 running on the return track 410. It should be noted that there is a second preset distance between the ranging end of the ranging component 10 in this application and the axle 452 of the tail star wheel. The second preset distance should be set according to actual needs. The ranging component 10 can be an ultrasonic sensor, an infrared sensor, a laser sensor, etc., which has the characteristics of high accuracy and good applicability, and can obtain high-precision distance values ​​in real time to facilitate corresponding judgments.

[0042] The image recognition component 20 is disposed on one side of the tail star wheel 450 and has a third preset distance between it and the toothed plate of the tail star wheel 450. The recognition end of the image recognition component 20 is directly opposite the transition connection between the return track 410 and the tail curve 411, and is used to detect the arching amount when the sintering machine trolley 420 leaves the tail star wheel 450 and enters the return track 410. There is a fourth preset distance between the recognition end of the image recognition component 20 and the ranging end of the ranging component 10.

[0043] Those skilled in the art should understand that the starting point and abrupt change of the arching of the return track 410 generally occurs when the sintering machine trolley 420 just leaves the toothed plate 451 of the tail star wheel and enters the horizontal section of the return track 410. In image representation, this is close to the point where the return track 410 is tangent to the tail star wheel 450. Since the space at this point is small, this application sets the image recognition component 20 near this point, and the image recognition component 20 can also be used to obtain the current arching amount of the sintering machine trolley 420. For example, the image recognition component 20 can be an industrial camera. Based on the installation distance between the industrial camera and the return track 410, by extracting the effective image recognition range, when each sintering machine trolley 420 enters the effective recognition range of the image recognition component 20, the maximum and minimum values ​​of the distance between the wheels of the sintering machine trolley 420 and the return track 410 can be obtained. For instance, the arching height value when the wheels of the sintering machine trolley 420 are directly opposite the recognition end of the image recognition component 20 can be used as a judgment benchmark to determine whether the current sintering machine trolley 420 exceeds the arching limit. The third preset distance and the fourth preset distance can both be set according to actual needs.

[0044] The ranging component 10, the image recognition component 20, and the arching adjustment component 30 are all electrically connected to the electronic control device. The tail star wheel 450 moves away from the head star wheel 440 of the sintering machine 40 along the axial direction of the frame 430 of the sintering machine under the drive of the arching adjustment component 30.

[0045] It should be further explained that, since the sintering machine trolleys 420 are connected front to back, with the trolley running behind pushing the trolley running in front, the factors involved in the arching of each sintering machine trolley 420 are complex. Subsequent sintering machine trolleys 420 may also have a further cumulative effect on the arching of the preceding sintering machine trolleys 420. Therefore, this application sets up the ranging component 10 to perform "secondary detection" on the sintering machine trolleys 420 running from the transition connection between the return track 410 and the tail curve 411, which can comprehensively and completely eliminate the arching of the sintering machine trolleys 420.

[0046] Working principle: When the sintering machine trolley 420 closest to the image recognition component 20 runs into the effective monitoring range of the image recognition component 20, the image information of the wheels of the effective sintering machine trolley 420 and the return track 410 in the current monitoring area is captured, and the arching amount of the current sintering machine trolley 420 is calculated. When the arching amount exceeds the preset value, the electronic control device receives the distance signal and controls the arching adjustment component 30 to start, so as to adjust the current sintering machine trolley 420. When the arching amount of the current sintering machine trolley 420 is lower than the preset value, but since subsequent trolleys may cause a cumulative effect on the sintering machine trolley 420 running ahead, when the current sintering trolley runs into the monitoring range of the ranging component 10, the electronic control device obtains the distance information detected by the ranging component 10. If the arching amount of the current sintering machine trolley 420 exceeds the set value, the electronic control device controls the arching adjustment component 30 to adjust the current sintering machine trolley 420.

[0047] In a preferred embodiment of the present invention, the arching adjustment assembly 30 includes a star wheel pushing mechanism 310 and a star wheel resetting mechanism 320. The star wheel pushing mechanism 310 is fixedly connected to the tail star wheel 450 and drives the tail star wheel 450 to move away from the head star wheel 440 of the sintering machine 40 along the axial direction of the frame 430 of the sintering machine. The star wheel resetting mechanism 320 is fixedly connected to the star wheel pushing mechanism 310 and pulls the tail star wheel 450 back to its initial position. In this embodiment, the arching adjustment of the sintering machine trolley 420 is achieved by controlling the cooperation of the star wheel pushing mechanism 310 and the star wheel resetting mechanism 320. The star wheel pushing assembly drives the head star wheel 440 to move away from the head star wheel 440 of the sintering machine 40 along the axial direction of the frame 430 of the sintering machine. For details, please refer to the appendix again. Figure 6-7 When the star wheel pushing mechanism 310 is not activated, trolley 2 422 and trolley 3 423 are tightly connected. When the star wheel pushing mechanism 310 is activated, the pushing force of the star wheel pushing mechanism 310 disconnects trolley 2 422 and trolley 3 423. At this time, the driving force of the head star wheel 440 cannot be transmitted to trolley 3 423 and the trolleys behind it. The trolleys on the return track 410 are temporarily in a near-stop state. The force of the tail star wheel 450 is only generated by the weight of the trolley meshing with the tail star wheel 450. Since the torque generated by the weight of the trolley is much greater than the upward component torque, the pressure is released, and the arching phenomenon disappears. Please refer to the appendix again. Figure 10As an auxiliary understanding, f1 is the frictional force of the tail star wheel tooth plate 451 on the wheel of the current sintering machine trolley, f2 is the thrust of the tail star wheel tooth plate 451 on the wheel of the sintering machine trolley, f3 is the frictional force of the sintering machine trolley running ahead on the current sintering machine trolley, f4 is the counter-thrust of the sintering machine trolley running ahead on the current sintering machine trolley, and G is the weight of the sintering machine trolley.

[0048] In other embodiments, force transmission between sintering machine trolleys 420 can be interrupted in other ways to eliminate or reduce arching. For example, the sintering machine trolleys 420 can be briefly intercepted at a certain point on the running track so that the front and rear sintering machine trolleys 420 do not come into contact. This method requires overcoming greater resistance to separate the front and rear sintering machine trolleys 420.

[0049] Further, the star wheel pushing mechanism 310 includes a driving component 311, a fixed frame 312, a sliding component 313, and a moving frame 314 extending vertically; wherein, the driving component 311 is fixed to the frame 430 of the sintering machine, the pushing end of the driving component 311 abuts against the sliding component 313, the sliding component 313 is movably arranged relative to the fixed frame 312, the fixed frame 312 is fixedly arranged relative to the frame 430 of the sintering machine, and the sliding component 313 is slidably arranged along the axial direction of the frame 430 of the sintering machine under the drive of the driving component 311; the top of the moving frame 314 is fixedly connected to the sliding component 313, and the bottom of the moving frame 314 is fixedly connected to the tail star wheel 450. Specifically, when it is necessary to adjust the arching of the sintering machine trolley 420, the electrical control device controls the drive assembly 311 to start. The drive end of the drive assembly 311 will push the sliding assembly 313 to move away from the head star wheel 440 along the axis of the sintering machine 40 fixture, and drive the tail star wheel 450 to move away from the head star wheel 440, thereby disconnecting the trolley 422 and the trolley 423 and eliminating the arching of the trolley.

[0050] In a preferred embodiment of the present invention, the star wheel reset mechanism 320 includes a counterweight 321, a first fixed pulley assembly 322, a second fixed pulley assembly 323, and a tension rope 324; wherein, the first fixed pulley assembly 322 is fixed to the movable frame 314, the second fixed pulley assembly 323 is fixed to the frame 430 of the sintering machine, the second fixed pulley assembly 323 is set lower than the first fixed pulley assembly 322 in the height direction, the fixed end of the tension rope 324 is fixedly connected to the frame 430 of the sintering machine, and the free end of the tension rope 324 is sequentially wound around the first fixed pulley assembly 322 and the second fixed pulley assembly 323, and then connected to the counterweight 321.

[0051] In detail, during a single push of the tail star wheel 450, to restore it to its normal initial state, this embodiment uses a fixed pulley system with a counterweight 321 to quickly return the tail star wheel 450 to its initial position. The initial position of the tail star wheel 450 can be adjusted by adjusting the weight of the counterweight 321. By using a first fixed pulley assembly 322 and a second fixed pulley assembly 323, the tail star wheel 450 can automatically and quickly reset itself when the driving force of the drive assembly 311 is removed or diminished, thanks to the action of the counterweight 321. In other embodiments, those skilled in the art can also restore the tail star wheel 450 to its initial position using other methods.

[0052] Further, the drive assembly 311 includes a mounting base 3111 and a hydraulic drive cylinder 3112; the mounting base 3111 is fixed to the frame 430 of the sintering machine, the pushing end of the hydraulic drive cylinder 3112 abuts against the sliding assembly 313, and the pushing direction of the hydraulic drive cylinder 3112 is arranged along the axial direction of the frame 430 of the sintering machine. In this embodiment, the drive assembly 311 adopts the hydraulic drive cylinder 3112. When adjustment is required, the electronic control device controls the hydraulic drive cylinder 3112 to drive the sliding assembly 313 to move along the axial direction of the sintering machine 40 and away from the head star wheel 440. It should be noted that the drive assembly 311 in this embodiment includes, but is not limited to, the hydraulic drive cylinder 3112. For example, it can also be an electric push rod, a drive cylinder, or a drive motor with gear transmission. Those skilled in the art can select according to actual needs, as long as it can smoothly push the tail star wheel 450.

[0053] In another preferred embodiment, the sliding assembly 313 includes a connecting frame 3131 and a sliding member 3132 movably disposed relative to the fixed frame 312. The sliding member 3132 is slidably disposed along the axial direction of the frame 430 of the sintering machine. The connecting frame 3131 is fixed to the sliding member 3132, and the connecting frame 3131 abuts against the pushing end of the driving assembly 311. The top of the moving frame 314 is fixedly connected to the sliding member 3132. In this embodiment, the sliding assembly 313 adopts a form in which the connecting frame 3131 and the sliding member 3132 cooperate. When the driving end of the driving assembly 311 pushes the connecting frame 3131, it will drive the sliding member 3132 to slide relative to the fixed frame 312. It can be understood that the specific form of cooperation between the sliding member 3132 and the fixed member can be selected as a guide rail and guide groove, or a sliding rail and groove, or a similar form.

[0054] Furthermore, the first fixed pulley assembly 322 includes a first pulley support 3221 and a first fixed pulley 3222 rotatably connected to the first pulley support 3221. The second fixed pulley assembly 323 includes a second pulley support 3231 and a second fixed pulley 3232 rotatably connected to the second pulley support 3231. The first pulley support 3221 is fixedly connected to the movable frame 314, and the second pulley support 3231 is fixedly connected to the frame 430 of the sintering machine. The first pulley support 3221 and the second pulley support 3231 have a fifth preset distance in the horizontal direction. The bottom of the first fixed pulley 3222 and the top of the second fixed pulley 3232 are flush. It should be noted that in this embodiment, the bottom of the first fixed pulley 3222 and the top of the second fixed pulley 3232 are flush. This allows the weight of the counterweight 321 to be converted into a pulling force in the horizontal direction to pull the tail star wheel 450 to the greatest extent. Of course, the two can also be set at an angle, but the latter will generate a vertical pulling force due to the angle. Obviously, the former will be more effective.

[0055] As an optional implementation, the ranging component 10 includes a first ranging component 110 and a second ranging component 120, wherein the first ranging component 110 and the second ranging component 120 are symmetrically arranged on both sides of the sintering machine trolley 420. In this embodiment, by symmetrically arranging the first ranging component 110 and the second ranging component 120 on both sides of the sintering machine trolley 420, and by combining the data acquired by the first ranging component 110 and the second ranging component 120, the monitoring accuracy is improved. For example, the average value of the first ranging component 110 and the second ranging component 120 can be used as the basis for judging whether the sintering machine trolley 420 has arched beyond the limit, thus improving the monitoring accuracy. It is understood that the number and setting position of the ranging components 10 can be set according to actual needs, but a reasonable and optimal judgment standard needs to be calculated by combining the data of multiple ranging components 10.

[0056] Furthermore, the width of the movable frame 314 is smaller than the diameter of the tail star wheel 450. In other embodiments, the width of the movable frame 314 can also be set to a specific size, depending on actual needs.

[0057] In addition, an identification plate 460 can be set on the side plate of each sintering machine trolley 420, which can be recognized by the image recognition component 20. The electronic control device can clearly obtain the corresponding number and position of the trolley based on the information of the identified identification plate 460, so that the staff can quickly locate it.

[0058] The present invention also provides a belt sintering machine 40, including a sintering machine body (not shown in the figure), the sintering machine body including a head star wheel 440 fixed on the frame 430 of the sintering machine, a tail star wheel 450 movably arranged along the axial direction of the frame 430 of the sintering machine, and a plurality of sintering machine trolleys 420 arranged around the head star wheel 440 and the tail star wheel 450; and also includes an automatic arching adjustment device for the sintering machine trolleys 420 as described above.

[0059] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
