Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical industry, and more particularly to a coke oven top automatic opening and closing furnace cover system, a control method thereof, and a furnace airing process. Background Art

[0002] The coke oven production process requires airing the next oven. This means opening the lid of the next oven in advance to allow for graphite sintering and coke cake shrinkage, which is beneficial for production. For example, in a 5-2 series, when oven N is loaded with coal, the lid of oven N+5 is opened for airing.

[0003] Previous furnace airing processes had the following drawbacks: opening and closing the furnace cover, cleaning the furnace cover and base, and sealing the slurry cap were all manual operations, resulting in a low degree of automation, high labor intensity, and a harsh working environment. A fully automated furnace airing process is a major trend in the industry.

[0004] Existing research has explored some aspects of oven airing automation, one of which is the design of an automated lid-lifting device. For example, Chinese patent application number CN117467460 A discloses a fully automatic oven airing system for a coke oven and its control method. The oven airing system includes a steel structure, a lid-lifting device, a furnace lid and furnace seat cleaning device, a mud sealing device, and a dust collection system. The steel structure serves as the skeleton of a top-loading coal car or a tamping smoke guide car. The lid-lifting device and the furnace lid and furnace seat cleaning device are mounted on the lower surface of the steel structure, located on both sides of the centerline of the oven airing hole. The lid-lifting device is used to lift and close the furnace lid, and the furnace lid and furnace seat cleaning device is used to clean the furnace lid and furnace seat. The mud sealing device is suspended behind the lid-lifting device and is used to transport mud to the mud trough where the furnace lid and furnace seat meet to achieve sealing. The dust collection system is arranged above the steel structure and is used to collect and purify the smoke and dust emitted from the oven airing hole. Although this application realizes the automation of the furnace drying process, the steel structure is the skeleton of the top-loading coal car or the tamping smoke guide car, resulting in poor flexibility of the furnace drying system.

[0005] For another example, the Chinese patent with publication number CN117165309A discloses an intelligent device for sealing the coal-loading hole on the furnace roof, which consists of an upper guide sleeve, a lower guide sleeve, a cover-lifting machine, a coal-loading hole cleaning machine, a furnace cover cleaning scraper, a slurry pouring system, a mobile trolley, and a guide rail frame. The upper guide sleeve and the lower guide sleeve cooperate to form three sealing points. The dry and wet diversion form is adopted to effectively avoid the problem of mud clogging the pipeline. Before use, water and dry powder are stored separately. When in use, the powder and water are quantitatively conveyed into the mixer and mixed. The mixed mud is released into the gap between the furnace cover and the coal-loading hole seat. After the slurry pouring is completed, the mixer is cleaned with a little clean water. Although this application realizes the automated operation of drying the furnace and loading coal, the guide rail frame is also installed and fixed on the coal-loading car, resulting in poor flexibility of the device.

[0006] The existing drying furnace device in the smoke guide hole seat on the top of the carbonization chamber has poor flexibility, which limits the progress of the existing drying furnace production process. Summary of the Invention

[0030] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0031] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, for the purposes of describing the embodiments of the present application herein.

[0032] In this application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "transverse", "longitudinal", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are mainly intended to better describe this application and its embodiments, and are not intended to limit the indicated devices, elements or components to having a specific direction, or to be constructed and operated in a specific direction. Moreover, in addition to being used to indicate directions or positional relationships, some of the above terms may also be used to indicate other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to the specific circumstances.

[0033] Regarding the following explanations of terms used in the present invention: the so-called "separable" refers to two objects that can be connected as a whole or separated into two parts; the "separable connection between the steel structure support frame 1 and the skeleton of the top-loading coal car or the tamping smoke guide car" referred to in the present invention means that the steel structure support frame 1 and the skeleton of the top-loading coal car or the tamping smoke guide car can be combined into a whole, in which case the top-loading coal car or the tamping smoke guide car drives the steel structure support frame 1 to move along the ground rail 6, or the two parts can be separated, in which case the steel structure support frame 1 can move along the ground rail 6 driven by the walking mechanism 7, that is, the steel structure support frame can move relative to the skeleton of the top-loading coal car or the tamping smoke guide car.

[0034] The so-called "single row of coke ovens" refers to a row of coke ovens arranged along the extension direction of the ground rail 6, that is, a row of coke ovens arranged along the movement direction of the coal charging car or the tamping smoke guide car. Example

[0035] This embodiment provides a coke oven top automatic opening and closing furnace cover system, referring to Figure 1-2 As shown, the automatic opening and closing furnace cover system includes a steel structure support frame 1, and the connection between the steel structure support frame 1 and the frame of the tamping smoke guide vehicle is detachable; a cover-lifting mechanism 3, which is installed on the steel structure support frame 1 and is used to lift the furnace cover of the smoke guide hole seat to dry the furnace; and a walking mechanism 7, which is installed on the lower part of the steel structure support frame 1 and is used to drive the steel structure support frame 1 to move along the ground rail 6.

[0036] Existing automatic cover opening and closing systems are typically integrated into the tamping and smoke guiding car frame. The oven airing process is limited by the distance between the automatic cover opening and closing system and the tamping and smoke guiding car frame. While the tamping and smoke guiding car is guiding smoke from coke oven No. N, the automatic cover opening and closing system is typically designed to air out coke oven No. N+5. This also limits the distance between the automatic cover opening and closing system and the smoke guiding mechanism in the tamping and smoke guiding car, significantly increasing the size of the tamping and smoke guiding car containing the automatic cover opening and closing system. Furthermore, before the tamping and smoke guiding car completes the smoke guiding of coke oven No. N, the automatic cover opening and closing system needs to close the cover of coke oven No. N+5, limiting the airing time.

[0037] It should be noted that if the automatic cover opening and closing system and the tamping smoke guide vehicle's framework are designed as two separate units that independently travel along the ground rails, they are considered separate devices, meaning they travel independently along the ground rails. The tamping smoke guide vehicle is typically operated by a driver, so the smoke guide vehicle's positional accuracy is relatively high. With this arrangement, the automatic cover opening and closing system's positional accuracy must be independently controlled as it travels along the ground rails. In steel mills, the paths of single-row coke ovens are typically long. Enabling the automatic cover opening and closing system to travel over long distances with high accuracy inevitably results in a more complex precision control system. Furthermore, the harsh on-site production environment limits the temperature tolerance of the hardware in traditional control systems, further raising the requirements for the control system used. Furthermore, the automatic cover opening and closing system and the tamping smoke guide vehicle share the same ground rails during movement. When the two travel relatively independently, interference between their motion trajectories must be avoided, further limiting the range within which the automatic cover opening and closing system can operate during coke oven airing. Consequently, this arrangement is costly to implement and has poor adaptability.

[0038] Based on the above reasons, the connection between the steel structure support frame 1 and the frame of the tamping smoke guide vehicle is designed to be detachable, that is, the connection between the automatic opening and closing furnace cover system for the coke oven top and the frame of the tamping smoke guide vehicle is designed to be detachable, and the steel structure support frame 1 and the frame of the tamping smoke guide vehicle can be connected as a whole, and the tamping smoke guide vehicle pushes the steel structure support frame 1 to move along the ground rail 6; the steel structure support frame 1 can also be separated from the frame of the tamping smoke guide vehicle, and at this time the steel structure support frame 1 can move along the ground rail 6 driven by the walking mechanism 7, so that the distance between the automatic opening and closing furnace cover system and the frame of the tamping smoke guide vehicle is more flexible.

[0039] When the tamping smoke guide car is guiding smoke to the Mth coke oven, the automatic opening and closing furnace cover system on the top of the coke oven is separated from the tamping smoke guide car and moves on the ground rail 6 along the forward direction of the tamping smoke guide car. The automatic opening and closing furnace cover system can dry the M+10th coke oven, that is, the coke oven to be guided smoke is dried one after another, and is not restricted by the fixed distance between the automatic opening and closing furnace cover system and the tamping smoke guide car frame. Before the tamping smoke guiding car completes the smoke guiding of coke oven No. M, the automatic opening and closing furnace cover system moves toward the direction close to the tamping smoke guiding car and is connected with it as a whole. When the tamping smoke guiding car completes the smoke guiding of coke oven No. M, the tamping smoke guiding car drives the automatic opening and closing furnace cover system to move synchronously to coke oven No. M+5, preparing for the next smoke guiding. After the tamping smoke guiding car stops, the automatic opening and closing furnace cover system moves to coke oven No. M+15 for airing. Before the tamping smoke guiding car completes the smoke guiding of coke oven No. M+5, the automatic opening and closing furnace cover system moves toward the direction close to the tamping smoke guiding car and is connected with it as a whole. During this process, the furnace cover of coke oven No. M+10 is covered, thereby delaying the airing time of coke oven No. M+10, thereby optimizing the airing process. When the automatic opening and closing furnace cover system moves toward the direction close to the tamping smoke guide vehicle and is connected with it as a whole, the starting position of the automatic opening and closing furnace cover system is reset to zero, that is, it uses the relative distance from the tamping smoke guide vehicle as the reference value of its movement distance, that is, it uses the position of the tamping smoke guide vehicle as a reference point, thereby simplifying the control of its position accuracy.

[0040] refer to Figure 3 、 Figure 4 As shown, the steel structure support frame 1 and the frame of the tamping smoke guide vehicle are detachably connected via a hook mechanism 2. The use of the hook mechanism 2 to achieve a detachable connection between the steel structure support frame 1 and the frame of the tamping smoke guide vehicle provides greater stability and simplifies the control process.

[0041] It should be noted that the specific implementation of the detachable connection between the steel structure support frame 1 and the frame of the tamping smoke guide vehicle is not limited by the above-mentioned hook mechanism 2, and it can also be achieved by other means such as electromagnetic adsorption.

[0042] Specifically, the hook mechanism 2 includes a hook mounting frame 201, a hook connecting frame 203, a first telescopic drive member 202 and a connecting rod assembly 204. The hook mounting frame 201 is fixedly mounted on the steel structure support frame 1, and the connecting rod assembly 204 is rotatably mounted on the hook mounting frame 201; the hook connecting frame 203 is fixedly mounted on the frame of the tamping smoke guide car, and a groove 231 is provided inside that is compatible with the connecting rod assembly 204; so as to realize a detachable connection between the structural support frame 1 and the frame of the top-loading coal car or the tamping smoke guide car.

[0043] Further preferably, the hook mounting frame 201 is provided with two relatively spaced apart hook connecting side plates 211, the connecting rod assembly 204 is located on the relatively inner sides of the two hook connecting side plates 211, the connecting rod assembly 204 includes two spaced apart transmission rods 242, the middle parts of the two rotating rods 241 are rotatably installed between the two hook connecting side plates 211 through the rotating rods 241, and one end close to the hook connecting frame 203 is fixedly connected by the hook matching rod 244, and the other end is fixedly connected by the connecting auxiliary rod 243; the hook matching rod 244 is used to snap into or out of the interior of the groove 231.

[0044] The other ends of the two transmission rods 242 are fixedly connected via a connecting auxiliary rod 243 , thereby improving the overall connection stability of the connecting rod assembly 204 .

[0045] More preferably, both ends of the rotating rod 241 are rotatably mounted on the two hook-connected side plates 211 through rolling bearings, and the middle portions of the two transmission rods 242 are fixedly sleeved on the outside of both ends of the rotating rod 241 .

[0046] In some embodiments, a tension spring 245 is further provided between the transmission rod 242 and the hook mounting frame 201; a limit rod 246 is further provided on the relative inner sides of the two hook connecting side plates 211, and the limit rod 246 is used to limit the downward rotation angle of the transmission rod 242 close to the hook connecting frame 203; the hook connecting frame 203 is further provided with a slope 232 on the side close to the hook mounting frame 201; the hook matching rod 244 contacts the slope 232 and slides along it to enable the hook matching rod 244 to be stuck into the interior of the groove 231; a first telescopic driving component 202 is also provided on the hook mounting frame 201, and the first telescopic driving component 202 is used to drive the hook matching rod 244 to disengage from the interior of the groove 231.

[0047] The limit rod 246 is used to limit the downward rotation angle of the transmission rod 242 near the hook connecting frame 203. When the steel structure support frame 1 returns, if the transmission rod 242 moves downward at a large angle, the bottom end of the hook engaging rod 244 will not be able to contact and slide along the slope 232, and the hook engaging rod 244 will collide with the hook connecting frame 203.

[0048] The ends of the tension spring 245 are respectively connected to the hook mounting frame 201 and the end of the transmission rod 242 near the hook connecting frame 203. The provision of the tension spring 245 not only ensures smooth rotation of the transmission rod 242 and prevents disordered rotation of the transmission rod 242, but also applies tension to the transmission rod 242 when the hook connecting frame 203 is engaged in the groove 231, maintaining the angle of the transmission rod 242 relatively stable and preventing the hook connecting frame 203 from falling out of the groove 231. When the hook connecting frame 203, driven by the first telescopic drive member 202, is released from the groove 231, and the first telescopic drive member 202 is removed, the tension spring 245 drives the transmission rod 242 to rotate in the opposite direction to return to its original position.

[0049] The process of using the hook mechanism 2 to achieve a detachable connection between the steel structure support frame 1 and the frame of the tamping smoke guide vehicle is as follows: in the initial position, the hook matching rod 244 in the hook mechanism 2 is located in the groove 231 in the hook mounting frame 201, and the first telescopic drive member 202 drives the transmission rod 242 to rotate in the direction away from the groove 231 in the hook mounting frame 201, and the hook matching rod 244 rotates upward to leave the groove 231 in the hook mounting frame 201, and the walking ground rail 7 drives the steel structure support frame 1 to move along the ground rail 6 away from the frame of the tamping smoke guide vehicle, thereby realizing the separation of the steel structure support frame 1 and the frame of the tamping smoke guide vehicle. During the return journey of the steel structure support frame 1, the traveling ground rail 7 drives the steel structure support frame 1 along the ground rail 6 toward the frame of the tamping smoke guide vehicle. The bottom end of the hook engaging rod 244 contacts the slope 232 and slides upward along it. As the distance between the steel structure support frame 1 and the tamping smoke guide vehicle frame gradually decreases, the hook engaging rod 244 moves to the top of the slope 232 and engages within the groove 231. When the hook engaging rod 244 engages within the groove 231, the tension spring 245 restricts the end of the transmission rod 242 near the hook connecting frame 203 from rotating upward, thereby preventing the hook mounting frame 201 from decoupling from the tamping smoke guide vehicle frame.

[0050] As an expansion solution, the first telescopic drive member 202 is preferably an electric cylinder, which is fixedly mounted on the hook connecting side plate 211 and is located above one end of the transmission rod 242 away from the hook matching rod 244. The movable end of the first telescopic drive member 202 does not need to be fixedly connected to the transmission rod 242. The first telescopic drive member 202 extends out, contacts the transmission rod 242 and pushes the transmission rod 242 to rotate around one end thereof, so that the hook matching rod 244 is disengaged from the inside of the groove 231.

[0051] Under the action of the elastic force of the tension spring 245 itself, the transmission rod 242 is rotated in the opposite direction to return to its original position.

[0052] As a further development solution, the number of the tension springs 245 is two, and the two tension springs 245 are located on the opposite inner sides of the two hook-connected side plates 211 and are symmetrically arranged relative to the two transmission rods 242 .

[0053] To detect whether the hook engaging rod 204 in the connecting rod assembly 204 is engaged with the interior of the groove 231, the hook mechanism 2 further includes a first detection assembly 205. The first detection assembly 205 includes a first proximity sensor 251 and a first sensing plate 252. The first proximity sensor 251 is mounted in the hook engaging rod 244. Accordingly, the hook connecting frame 203 is provided with a first sensing plate 252 for sensing by the first proximity sensor 251. Preferably, the top surface of the first sensing plate 252 is flush with the bottom surface of the groove 231 in the hook connecting frame 203. As the bottom end of the hook engaging rod 244 contacts the slope 232 and slides upward along it, when the hook engaging rod 244 is engaged with the interior of the groove 231, the first proximity sensor 251 in the hook engaging rod 244 senses the first sensing plate 252 in the hook connecting frame 203, thereby detecting that the hook engaging rod 204 is engaged with the interior of the groove 231.

[0054] In order to detect whether the end of the transmission rod 242 close to the hook connecting frame 203 is in contact with the slope 232, the hook mechanism 2 also includes a second detection component 206, and the second detection component 206 also includes a second proximity sensor 261 and a second sensing plate 262. The second proximity sensor 261 is fixedly installed on the hook connecting side plate 211, and the sensing end is set toward the transmission rod 242; the second sensing plate 262 is preferably arc-shaped and fixedly installed on the side of the transmission rod 242 close to the hook connecting side plate 211.

[0055] When the hook engaging rod 204 is released from the interior of the groove 231, the angle of the transmission rod 242 in the connecting rod assembly 204 is relatively constant under the limitation of the tension spring 245. At this time, the second sensing plate 262 is facing the second proximity sensor 261. The running ground rail 7 drives the steel structure support frame 1 in its return journey, that is, drives the steel structure support frame 1 along the ground rail 6 to move close to the frame of the tamping smoke guide vehicle. The bottom end of the hook engaging rod 244 contacts the slope 232 and slides upward along it. During this process, the end of the transmission rod 242 near the hook connecting frame 203 gradually rotates upward, that is, the other end of the transmission rod 242 rotates downward, causing the second sensing plate 262 to move downward relative to the second proximity sensor 261 and leave the sensing area of ​​the second proximity sensor 261. The control system of the automatic opening and closing furnace cover system receives a signal indicating that the steel structure support frame 1 has begun to contact the frame of the tamping smoke guide vehicle.

[0056] As a further preferred embodiment of any of the above embodiments, refer to Figure 1 、 Figure 2 、 Figure 5-7 As shown, the automatic opening and closing furnace cover system also includes a furnace hole cleaning mechanism 4, which is installed on the steel structure support frame 1 and is used to clean the inner wall of the smoke guide hole seat.

[0057] As a preferred embodiment of the furnace hole cleaning mechanism 4, refer to Figure 5-7 As shown, the furnace hole cleaning mechanism 4 includes a cleaning head assembly 407, a second telescopic drive member 402 and a cleaning drive member 404, wherein the second telescopic drive member 402 is used to drive the cleaning head assembly 407 to move in the vertical direction, and the cleaning drive member 404 is used to drive the cleaning head assembly 407 to rotate around the vertical direction. The cleaning head assembly 407 includes a turntable and a plurality of chain connecting buckles 471, and the plurality of chain connecting buckles 471 are evenly spaced along the circumferential direction of the turntable on its outer ring, and each chain connecting buckle 471 is correspondingly provided with a chain 472, and a wire brush head 473 is provided at the other end of the chain 472 away from the turntable.

[0058] Specifically, the furnace hole cleaning mechanism 4 includes a cleaning mounting frame 401, a cleaning movable frame 403 and a cleaning head assembly 407. The second telescopic drive member 402 is installed on the top of the cleaning mounting frame 401. The cleaning mounting frame 401 is fixedly installed on the steel structure support frame 1, and the interior is a hollow structure; a cleaning movable frame 403 is also provided inside the cleaning mounting frame 401; the telescopic end of the second telescopic drive member 402 is fixedly connected to the top of the cleaning movable frame 403; the cleaning drive member 404 is installed on the cleaning movable frame 403; one end of the cleaning main shaft is rotatably installed on the cleaning movable frame 403, and the other end is fixedly connected to the turntable in the cleaning head assembly 407. The cleaning drive member 404 is used to drive the cleaning main shaft to rotate.

[0059] More specifically, the wire brush head 473 is provided with an open end, and the wire brush head 473 is sleeved on the outside of the end link of the chain 472; the open end of the wire brush head 473 is provided with a limit buckle 474 sleeved on the outside thereof, which is used to prevent the wire brush head 473 from falling off from the link hole of the chain 472.

[0060] The cleaning principle of the cleaning head assembly 407 is as follows: when the turntable is not rotating, the chain 472 is naturally suspended by gravity. Figure 7 The state indicated by B in the figure; when the rotation speed of the turntable reaches a certain value, refer to Figure 7 From the perspective shown, the chain 472 gradually changes from the state indicated by B to the state indicated by A.

[0061] The specific cleaning process of the furnace hole cleaning mechanism 4 is as follows: the second telescopic drive member 402 drives the cleaning movable frame 403 and its upper components to descend to a certain depth inside the smoke guide hole seat. At this time, there is a large gap between the chain 472 and the inner wall of the smoke guide hole seat. The cleaning drive member 404 drives the cleaning main shaft to rotate, and then drives the turntable and its upper components to rotate. The gap between the end of the chain 472 away from the turntable and the inner wall of the smoke guide hole seat gradually decreases, and the wire brush head 473 contacts the inner wall of the smoke guide hole seat to clean the inner wall of the smoke guide hole seat.

[0062] In the furnace hole cleaning mechanism 4 of the present invention, the cleaning head assembly 407 utilizes a chain 472 to flexibly adjust the spacing between the cleaning wire brush 473 and the inner wall of the smoke guide hole. When the contact force between the wire brush 473 and the inner wall of the smoke guide hole is excessive, the chain 472 automatically adjusts the relative distance between its links, thereby preventing excessive cleaning force. Furthermore, the distance between adjacent links in the chain 472 automatically adjusts under the action of external forces, thereby reducing the requirement for coaxiality between the central axis of the cleaning head assembly 407 and the inner wall of the smoke guide hole. More importantly, this prevents blind spots from forming during cleaning of the inner wall of the smoke guide hole.

[0063] The second telescopic driving member 402 drives the cleaning movable frame 403 to move relative to the inner wall of the smoke guide hole seat along its axial direction, thereby completing the cleaning of different heights of the inner wall of the smoke guide hole seat.

[0064] In order to reduce the swing of the cleaning spindle when it rotates away from the bottom end of the cleaning movable frame 403, the furnace hole cleaning mechanism 4 also includes a cleaning head connecting rod 406 that is sleeved on the outside of the cleaning spindle. The upper end of the cleaning head connecting rod 406 is fixedly connected to the cleaning movable frame 403, and the lower end is installed on the bearing that supports the rotation of the cleaning spindle.

[0065] To improve the stability of the sliding movement of the cleaning movable frame 403 relative to the cleaning mounting frame 401, a cleaning telescopic guide assembly 405 is provided between the cleaning movable frame 403 and the cleaning mounting frame 401. The slider and rail assembly used in the cleaning telescopic guide assembly 405 will not be described in detail here. Specifically, two cleaning telescopic guide assemblies 405 are provided on opposite outer sides of the cleaning mounting frame 401, and the two sides of the cleaning head connecting rod 406 are fixedly connected to the opposite inner sides of the two cleaning telescopic guide assemblies 405.

[0066] In order to realize the above optimized drying process, refer to Figure 1 、 Figure 2 As shown, at least two covering mechanisms 3 are provided above the smoke guide hole seat of a single row of coke ovens, one of which covers the coke oven that has finished airing, i.e., the next coke oven to be guided to guide smoke, and the other covering mechanism 3 covers the next coke oven to be guided to guide smoke.

[0067] The cover mechanism 3 is mounted on the steel support frame 1. The specific mounting position of the cover mechanism 3 on the steel support frame 1 is determined based on the location of the coke oven smoke guide holes in the on-site production environment. For conventional two rows of coke oven smoke guide holes spaced apart, two or more cover mechanisms 3 are positioned directly above each row of coke oven smoke guide holes.

[0068] The specific action process of the automatic opening and closing furnace cover system is as follows: S1, when the tamping smoke guide car or the top-loading coal car drives the steel structure support frame 1 to the preset position of the No. N coke oven, and the tamping smoke guide car guides smoke to the coke oven or the top-loading coal car loads coal to the coke oven, the steel structure support frame 1 and the skeleton of the top-loading coal car or the tamping smoke guide car in the automatic opening and closing furnace cover system are separated; if the No. N coke oven is the first coke oven to be operated during the unidirectional movement of the tamping smoke guide car or the top-loading coal car along the ground rail, then execute step S2; otherwise, execute step S3. In step S2, the traveling mechanism 7 drives the steel structure support frame 1 to travel along the ground rail 6 in a direction away from the tamping smoke guide car or the top-loading coal car. The cover mechanism 3 sequentially removes the covers of the N+mth and N+2mth coke ovens, and the furnace hole cleaning mechanism 4 cleans the inner walls of the corresponding smoke guide hole seats. Where m is the difference in the corresponding coke oven numbers between the two operations of the tamping smoke guide car or the top-loading coal car. The process then continues with step S4. In step S3, the traveling mechanism 7 drives the steel structure support frame 1 to travel along the ground rail 6 in a direction away from the tamping smoke guide car or the top-loading coal car. The cover mechanism 3 removes the cover of the N+2mth coke oven, and the furnace hole cleaning mechanism 4 cleans the inner wall of the corresponding smoke guide hole seat. Where m is the difference in the corresponding coke oven number between the two operations of the tamping smoke guide car or the top-loading coal car. The process then continues with step S4. S4, before the tamping smoke guide car or the top-loading coal car completes the operation on the Nth coke oven, the walking mechanism 7 drives the steel structure support frame 1 to return, and the steel structure support frame 1 is connected to the skeleton of the top-loading coal car or the tamping smoke guide car; during the return process, the cover mechanism 3 closes the cover of the N+mth coke oven.

[0069] It should be noted that, in the above oven airing process, the difference m between the two operations of tamping smoke guide car or top loading coal car corresponding to the coke oven number is generally selected to be 5, which can also be modified to other values ​​to adapt to the on-site coke oven layout environment.

[0070] By adopting the above oven airing process, except for the first coke oven that is uncovered for airing, the airing time of other coke ovens is approximately doubled compared with the existing oven airing process.

[0071] As a preferred embodiment of the cover mechanism 3, refer to Figure 8-Figure 9 As shown, the cover-lifting mechanism 3 includes a furnace cover placement detection component 306, a cover-lifting gripper 305 and a third telescopic drive member 302. The third telescopic drive member 302 is used to drive the cover-lifting gripper 305 to move in the vertical direction. The furnace cover placement detection component 306 is arranged inside the cover-lifting gripper 305 and is used to detect whether the furnace cover is correctly placed on the smoke guide hole seat of the coke oven.

[0072] Furthermore, the furnace cover placement detection component 306 includes a limit switch, which is installed at the top of the interior of the lid-lifting gripper 305 and is used to detect whether the height of the furnace cover inside the lid-lifting gripper 305 exceeds a set value.

[0073] Among them, the furnace cover used for the smoke guide hole seat of the coke oven is a water-sealed cover, because it does not require grouting treatment, and the use of a water-sealed cover is more in line with the environmental protection development trend of the steel plant.

[0074] When the furnace cover is tilted to the horizontal plane, that is, the furnace cover is not placed horizontally in the water seal groove, the top of the furnace cover contacts the limit switch, causing it to be triggered. At this time, the machine needs to be stopped for inspection.

[0075] Furthermore, the third telescopic drive member 302 is fixedly mounted on the steel structure support frame 1 through the cover mounting frame 301, and the third telescopic drive member 302 is mounted on the top of the cover mounting frame 301; the interior of the third telescopic drive member 302 is a hollow structure; the cover gripper connecting rod 303 is located inside the cover mounting frame 301, and the top end is fixedly connected to the telescopic end of the third telescopic drive member 302, and the bottom end is fixedly connected to the top of the cover gripper 305.

[0076] In order to ensure the stability of the vertical sliding of the cover gripper connecting rod 303 relative to the cover mounting frame 301, a cover guide telescopic guide component 304 is provided between the cover mounting frame 301 and the side wall of the cover gripper connecting rod 303. The cover guide telescopic guide component 304 is preferably a guide wheel.

[0077] As an extension solution, the remaining structure of the cover-lifting gripper 305 is preferably the same as the cover-lifting mechanism on the existing tamping smoke guide vehicle, so as to be better adapted to the existing tamping smoke guide vehicle.

[0078] As a preferred embodiment of the traveling mechanism 7, the traveling mechanism 7 includes a traveling motor 701, which drives the steel structure support frame 1 along the ground rail 6 via a transmission assembly. A clutch is provided between the traveling motor 701 and the transmission assembly to disconnect or connect the power transmission between the two. When the steel structure support frame 1 is connected to the tamping smoke guide vehicle as an integral unit, that is, the furnace cover opening and closing system is driven by the tamping smoke guide vehicle, the power transmission between the traveling motor 701 and the transmission assembly is disconnected, thereby reducing wear on the traveling motor 701 and the travel wheels of the traveling mechanism 7.

[0079] When the steel structure support frame 1 in the switch furnace cover system is connected to the skeleton of the tamping smoke guide vehicle, the tamping smoke guide vehicle drives the automatic switch furnace cover system to move synchronously along the ground rail 6; when the skeleton of the tamping smoke guide vehicle is stationary, and the steel structure support frame 1 in the switch furnace cover system is separated from the skeleton of the tamping smoke guide vehicle, the walking mechanism 7 drives the steel structure support frame 1 in the switch furnace cover system to move along the ground rail 6. The walking mechanism 7 uses the position of the tamping smoke guide vehicle as a reference point for its walking process, which is convenient for controlling the position accuracy of the walking process of the automatic switch furnace cover system. Example

[0080] The difference between this embodiment and embodiment 1 is that the connection between the steel structure support frame 1 and the frame of the top-loading coal car is detachable; the rest of the structure is basically the same, that is, the switch furnace cover system is also suitable for top-loading coke ovens.

[0081] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
