Description

Technical Field

[0001] This application relates to the field of coke cooling or quenching technology, specifically to a coke can opening / closing device and a coking production system. Background Technology

[0002] In the coking process, the coke can, as the core equipment carrying high-temperature coke, plays a crucial role in improving production efficiency, optimizing environmental protection, and ensuring production safety through its sealing treatment. Sealing the coke can effectively reduce heat loss from the high-temperature coke, lower the impact of heat radiation on the surrounding environment, and suppress fugitive dust emissions during coke transfer, aligning with the current development needs of the coking industry for green, low-carbon, high-efficiency, and energy-saving practices. However, research has revealed that existing coke can sealing technologies mainly fall into two categories: The first method is a fixed-point automatic capping / uncapping scheme. This scheme requires the coke tank car to be precisely aligned with a preset fixed point to complete the capping / uncapping action. This scheme requires an additional 2-3 minutes for each capping / uncapping process. However, in current coking production, some operating conditions require a tight production cycle of ≤8.5 minutes / cycle. The extra time consumed by this scheme is too long, which will seriously restrict the overall capacity of the coke oven and cannot adapt to the tight production cycle.

[0003] The second type is the integrated cover solution for coke tank cars. This type of solution includes various sub-technical paths such as four-link cover, sliding cover, foldable insulated cover, and sliding lifting cover. However, it requires significant structural modifications to existing dual-tank coke tank cars. Not only does it require adjusting the tank spacing, but it also requires redesigning the vehicle's load-bearing structure. The modification cycle is long and costly, and it has a significant impact on the existing production layout. At the same time, the integration of the cover device into the coke tank car causes a dynamic change in the center of gravity of the cover, which in turn causes uneven and unstable force on the drive device, limiting the speed of the opening / closing action and making it unsuitable for high-speed production. In addition, the sealing performance of this type of solution is generally poor, which easily leads to flue gas leakage, affecting the purification effect of the coke dust removal system and making it difficult to meet environmental emission requirements. 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 coke can opening / closing device, comprising: A fixed frame is provided, on which two fork tooth assemblies are installed. Each fork tooth assembly includes at least one fork tooth. The upper end of each fork tooth is provided with a ramp and a placement platform distributed at the end of the ramp. The height of the ramp gradually increases along a first direction, which is the running direction of the transport vehicle. The upper end of the can lid is provided with two hook assembly assemblies. Each hook assembly includes at least one hook member. The two hook assembly assemblies correspond to the two fork tooth assemblies respectively, and each hook member is provided with a hook interface for the corresponding fork tooth to be inserted. A lifting mechanism is installed on a transport vehicle and is distributed at intervals with the coke tanks along a direction away from the first direction; The hanging ear is installed on the can lid and corresponds vertically to the lifting mechanism. The lower end of the hanging ear is provided with an insertion groove for accommodating the lifting end of the lifting mechanism, and the side of the hanging ear corresponding to the first direction is provided with a notch, which communicates with the insertion groove.

[0005] One embodiment of the present invention adopts a technical solution to solve its technical problem as follows: the two fork tooth groups are a first fork tooth group and a second fork tooth group, the second fork tooth group is distributed at intervals with the first fork tooth group along a first direction, and a receiving groove is provided on the placement platform of the first fork tooth group.

[0006] One embodiment of the present invention adopts the following technical solution to solve its technical problem: the hanging component includes a guide wheel and two brackets, the two brackets are horizontally spaced along a second direction and installed at the upper end of the can lid, the guide wheel is rotatably installed at the upper end of the two brackets through a wheel axle, and the hanging interface is formed between the guide wheel and the two brackets.

[0007] The technical solution adopted by one embodiment of the present invention to solve its technical problem is: each fork tooth group includes two fork teeth, the two fork teeth are horizontally spaced along a second direction, and the second direction is perpendicular to the first direction.

[0008] One embodiment of the present invention adopts a technical solution to solve its technical problem as follows: the fixing frame is a gantry bracket, two fork tooth groups are installed at the lower end of the gantry bracket, and the transport vehicle can pass through the gantry bracket.

[0009] One embodiment of the present invention provides a technical solution to solve its technical problem by comprising two lifting rods in each lifting mechanism.

[0010] One embodiment of the present invention provides a technical solution to solve its technical problem by further including a running track and sensors disposed on the running track, wherein the sensors are distributed on one side of the fixed frame and the sensors are used to detect the transport vehicle.

[0011] This application also discloses a coking production system, including a running track and the aforementioned coke can opening / closing device, and further including a lifting tower or coke quenching car. The running track is connected to the entrance of the lifting tower or coke quenching car, the fixed frame is set at the entrance of the lifting tower or coke quenching car, and the transport vehicle is set on the running track and can move along the running track to enter the lifting tower or coke quenching car after passing the fixed frame.

[0013] One embodiment of the present invention adopts a technical solution to solve its technical problem as follows: the hanging ears on both sides of the can lid are separated from each other along the projection of the transport vehicle in the direction of travel.

[0014] The beneficial effects of this invention are as follows: It eliminates the need for precise positioning of the transport vehicle, allowing the capping / uncapping action to be completed during travel, completely solving the problem of additional time consumption associated with existing fixed-point solutions. This adapts to tight production cycles and increases coke oven capacity. Furthermore, it utilizes the movement of the coke car itself for driving power, eliminating the need for an external power source. As the coke car travels past the device, the structural design automatically completes the capping or uncapping action, achieving fully automated operation with immediate capping after coke discharge and automatic capping before lifting, all without manual intervention. The interconnected design of the lug notch and insertion slot improves the docking efficiency between the lifting end and the lug. Combined with the structure of the fork ramp and placement platform, it ensures smooth operation. Simultaneously, the excellent sealing performance of the cap effectively suppresses dust leakage, meeting environmental protection requirements. Attached Figure Description

Those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution. Example

[0020] Reference Figures 1 to 6 As shown in Embodiment 1 of this application, the coke can opening / closing device of this embodiment includes: A fixing frame 10 is equipped with two fork tooth groups 20. Each fork tooth group 20 includes at least one fork tooth 21. The upper end of each fork tooth 21 is provided with a ramp 211 and a placement platform 212 distributed at the end of the ramp 211. The height of the ramp 211 gradually increases along a first direction, which is the running direction of the transport vehicle 30. The upper end of the can cover 40 is provided with two hook-fitting groups 50. Each hook-fitting group 50 includes at least one hook-fitting member 51. The two hook-fitting groups 50 correspond to the two fork tooth groups 20 respectively. Each hook-fitting member 51 is provided with a hook interface 52 for the corresponding fork tooth 21 to be inserted. A lifting mechanism 60 is installed on the transport vehicle 30, and the lifting mechanism 60 is distributed at intervals with the coke tank 70 along a direction away from the first direction; The hanging ear 80 is installed on the can lid 40 and corresponds vertically to the lifting mechanism 60. The lower end of the hanging ear 80 is provided with an insertion groove 81 for accommodating the lifting end of the lifting mechanism 60, and the side of the hanging ear 80 corresponding to the first direction is provided with a notch 82, which is connected to the insertion groove 81.

[0021] The first direction is defined as the running direction of the transport vehicle 30, i.e., the direction in which the transport vehicle 30 travels on the track. Two fork sets 20 are distributed at intervals along this direction, namely the first fork set and the second fork set. The distance between them is designed to be adapted to the length of the transport vehicle 30, the arrangement position of the coke can 70, and the size of the can lid 40, to ensure that the can lid 40 can accurately cover the opening of the coke can 70 after being attached. The number of forks 21 in each fork set 20 can be adjusted according to the weight of the can lid 40 and the uniformity of force. In this embodiment, each fork set 20 includes two forks 21 to ensure stability. The upper end is integrally formed with a ramp 211 and a placement platform 212. The height of the ramp 211 gradually increases along the first direction, forming a smooth guide slope.

[0022] The lifting mechanism 60 is fixedly installed on the transport vehicle 30 and is distributed at intervals with the coke tank 70 along a horizontal direction away from the first direction. The lifting mechanism 60 includes two lifting rods, preferably hydraulic lifting rods, which have the advantages of sufficient power, smooth operation and strong load-bearing capacity, and are suitable for coking production conditions such as high temperature and dust.

[0023] The lug 80 is welded to the can lid 40 and precisely corresponds to the lifting mechanism 60 vertically, ensuring that the lifting mechanism 60 can stably transmit force to the can lid 40 when it operates. The lower end of the lug 80 has an insertion groove 81, the inner diameter of which matches the outer diameter of the lifting end of the lifting mechanism 60, ensuring that the lifting end does not wobble after insertion and can stably drive the can lid 40 to rise and fall. The lug 80 has a notch 82 on the side corresponding to the first direction, providing clearance for the lifting end to dock with and disengage from the insertion groove 81, so that the lifting end can be quickly inserted into or removed from the insertion groove 81 without precise alignment, which is suitable for the dynamic operation requirements of the transport vehicle 30 during travel.

[0024] The working principle of the lid-opening mechanism includes: (Refer to the attached document) Figure 4 As shown, taking the coke tank 70 carried by the transport vehicle 30 traveling from left to right as the first direction as an example, before the coke tank 70 carried by the transport vehicle 30 travels from left to right to the bottom of the fixed frame 10, the hook interface 52 of the two hook assembly 50 at the upper end of the tank cover 40 corresponds to the lower end of the two fork tooth assembly 20; at this time, the lifting mechanism 60 is in the extended state and inserted into the insertion slot to support the tank cover 40; See attached document Figure 5 As shown, the transport vehicle 30 carrying the coke can 70 continues to travel from left to right. The hook assembly 50 at the upper end of the can cover 40 moves synchronously with the transport vehicle. The hook interface 52 gradually approaches the corresponding fork tooth assembly 20. As the can cover 40 moves from left to right, the hook interface 52 slides up along the ramp 211 during the movement, thereby slowly raising the can cover 40 until the hook interfaces 52 of the two hook assembly 50 just move into the placement platform 212 at the end of the ramp 211. At this time, the height of the lifting mechanism 60 is exactly corresponding to the notch 82, so that the can cover 40 is hooked on the two fork tooth assemblies 20. The transport vehicle 30 carrying the coke can 70 continues to travel from left to right. The transport vehicle 30, carrying the coke can 70, continues to travel from left to right, passing the can cover 40 and approaching the target equipment to complete the opening action.

[0025] How the lid works: After the transport vehicle 30 exits from the lifting tower or coke quenching car, it travels in the opposite direction along the running track 90 to the fixed frame 10. The transport vehicle 30 carries the coke can 70 and moves from right to left until the lifting mechanism 60 is below the insertion slot 81. As it continues to move, the lifting mechanism 60 pushes the hanging lug 80 to the left. At this time, the hanging interface 52 of the can cover 40 moves to the left under the pushing action of the lifting mechanism 60 and first separates from the placement platform 212. Then it descends along the slope 211 and covers the upper end of the coke can 70, completing the covering of the coke can 70.

[0026] In this application, precise positioning of the transport vehicle 30 is not required; the opening / closing action can be completed during travel, completely solving the problem of additional time consumption in the existing fixed-point solution. This adapts to a compact production cycle and increases coke oven capacity. Furthermore, the coke can 70 utilizes its own movement to provide driving power, eliminating the need for an additional power source. When the coke can 70 travels past the device, the structural design automatically completes the closing or opening action of the can lid 40, achieving fully automated operation of immediately closing the lid after coke discharge and automatically opening the lid before lifting, without any manual intervention. The connection design between the notch 82 of the lug 80 and the insertion slot 81 improves the docking efficiency between the lifting end and the lug 80. Combined with the structure of the fork 21, the ramp 211, and the placement platform 212, it ensures smooth operation. At the same time, the can lid 40 has excellent sealing performance, effectively suppressing dust leakage and meeting environmental protection requirements.

[0027] The can lid 40 adopts a composite structure design of steel frame and high-performance heat-resistant lining, which meets the requirements of heat insulation, sealing, high temperature resistance, lightweight and long-term reliability. The steel frame material is made of high-strength heat-resistant steel to ensure structural strength; the heat-resistant lining uses high-performance fire-resistant and heat-insulating material to reduce heat radiation conduction and ensure a tight seal with the can lid 70 to prevent flue gas from escaping.

[0028] Preferably, the two fork tooth groups 20 are the first fork tooth group and the second fork tooth group, respectively. The second fork tooth group is distributed at intervals with the first fork tooth group along the first direction, and the placement platform 212 of the first fork tooth group is provided with a receiving groove 213.

[0029] When the can lid 40 is suspended on the two fork tooth assemblies 20, the left-side hook assembly will be accommodated and limited in the receiving groove to ensure the suspension stability of the can lid 40.

[0030] Preferably, the mounting bracket 51 includes a guide wheel 511 and two brackets 512. The two brackets 512 are horizontally spaced along the second direction and mounted on the upper end of the can lid 40. The guide wheel 511 is rotatably mounted on the upper end of the two brackets 512 via a wheel axle. The mounting interface 52 is formed between the guide wheel 511 and the two brackets 512.

[0031] The guide wheel 511 is rotatably mounted on the upper end of the two brackets 512 via axles. The two ends of the axles are connected to the brackets 512 via high-precision bearings to ensure that the guide wheel 511 can rotate flexibly without radial wobble. A hook interface 52 is formed between the guide wheel 511 and the two brackets 512. The width of the hook interface 52 is slightly larger than the thickness of the fork tooth 21. During the opening / closing process, the fork tooth 21 is inserted into the hook interface 52 formed by the guide wheel 511 and the brackets 512. The guide wheel 511 rotates around the axle, converting the sliding friction between the hook interface 52 and the fork tooth 21 into rolling friction, which greatly reduces the fitting resistance and makes the lifting, lowering and detachment of the can lid 40 along the slope 211 smoother, avoiding jamming.

[0032] Preferably, each fork assembly 20 includes two fork teeth 21, which are horizontally spaced along a second direction, perpendicular to the first direction. During the opening / closing process, the two fork teeth 21 of each fork assembly 20 are simultaneously inserted into the hook interfaces 52 of the two hooks 51 on the corresponding side of the can lid 40, providing support from both sides of the can lid 40. Compared to a single fork tooth 21, the double fork tooth 21 structure can effectively distribute the weight of the can lid 40, ensuring that the can lid 40 maintains a horizontal or preset tilted posture during lifting, hooking, and closing, accurately covering the opening of the coke can 70.

[0033] In this embodiment, the fixing frame 10 is a gantry-shaped bracket, and two fork tooth assemblies 20 are installed at the lower end inside the gantry-shaped bracket, allowing the transport vehicle 30 to pass through the gantry-shaped bracket.

[0034] The fixed frame 10 is a portal frame, consisting of four uprights and a crossbeam positioned between them. The uprights are made of H-beams and fixed to the ground foundation with expansion bolts. The crossbeams are welded to the upper ends of the two uprights, forming a stable portal frame structure with excellent impact resistance and load-bearing capacity. Two fork tooth assemblies 20 are installed at the lower ends of the crossbeams within the portal frame, spaced apart along the first direction. The fork teeth 21 extend vertically downwards. The internal width of the portal frame is slightly larger than the width of the transport vehicle 30, and its height is adapted to the overall height of the coke tank 70 and the tank cover 40, ensuring that the transport vehicle 30 can smoothly pass between the two uprights of the portal frame, and that the tank cover 40 can accurately cover the coke tank 70 on the transport vehicle without spatial interference. The transport vehicle 30 carries the coke can 70 and travels along the running track 90. ​​It enters from the entrance end of the portal frame and, while passing through the interior of the frame 512, completes the opening / closing action of the can lid 40. Then, it exits from the exit end of the frame 512 and smoothly enters the lifting tower 100 or the coke quenching car 110 to complete subsequent processes. The open structure of the portal frame does not occupy additional space on both sides of the track and can be directly adapted to the existing site layout of coking production without adjusting the position of surrounding equipment.

[0035] Preferably, the system also includes a running track 90 and sensors disposed on the running track 90, with the sensors distributed on one side of the mounting frame 10, and the sensors are used to detect the transport vehicle 30.

[0036] The running track 90 is a dedicated travel track for the transport vehicle 30. The track material and specifications are compatible with the existing coking production system to ensure smooth travel of the transport vehicle. The sensors on the running track 90 are high-precision photoelectric sensors, which are fixed to the side of the running track 90 near the entrance end of the fixed frame 10 by brackets 512. The detection direction is towards the track, and they are used for real-time detection of the transport vehicle 30. The sensors are electrically connected to the control system of the transport vehicle 30 and the drive system of the lifting mechanism 60 to form an automated linkage control and realize unmanned operation.

[0037] When the transport vehicle 30 travels along the running track 90 toward the fixed frame 10, the sensor detects that the transport vehicle is approaching and immediately sends a signal to the control system. The control system controls the lifting mechanism 60 to switch to extension according to the preset parameters to ensure that the can lid 40 and the fork tooth assembly 20 are precisely matched.

[0038] Preferably, the coke can 70 and the hanger 15 are also equipped with sensors. The sensors are high-temperature resistant proximity sensors. The sensors on the coke can 70 are embedded in the upper edge, and the sensors on the fixing frame 10 are mounted on the hanger 51, respectively and precisely corresponding to the lower edge of the can lid 40 or the fork tooth group 20. They are used to detect whether the can lid 40 has been successfully put on or taken off.

[0039] During the capping operation, the sensor simultaneously detects whether the can lid 40 is tightly fitted to the upper edge of the coke can 70, and whether the hook interface 52 is completely disengaged from the fork tooth assembly 20. Only when both indicators meet the standards can the capping be considered successful. If the can lid 40 is found to be not accurately covering the coke can 70, or if there is a gap, or if the hook interface 52 is not completely disengaged from the fork tooth 21, resulting in uneven force on the can lid 40, a fault signal is immediately sent to the control system. The control system quickly triggers the interlocking mechanism, prohibiting the transport vehicle 30 from starting and running. At the same time, the audible and visual alarm device is activated to promptly remind maintenance personnel to investigate the cause of the fault, such as the can lid 40 being offset, the lifting mechanism 60 not moving synchronously, or the fork tooth 21 being stuck.

[0040] During the unloading operation, the sensor also detects two things: whether the can lid 40 is completely detached from the upper end of the coke can 70 and whether the connector 51 is fully engaged in the placement platform 212 of the fork assembly 20, ensuring that the can lid 40 is stably attached to the fixing frame 10. If the can lid 40 is not completely detached from the coke can 70, or the connector 51 is not accurately engaged in the placement platform 212, resulting in unstable attachment, a fault signal is immediately sent, and the control system immediately locks the operating permission of the transport vehicle 30, prohibiting the transport vehicle from driving, to avoid safety accidents such as equipment interference, can lid 40 falling off, and dust leakage caused by driving with the lid on. Example

[0041] See attached document Figure 7-11 As shown, based on the content described in Embodiment 1, this application also proposes Embodiment 2 of a coking production system. Embodiment 2 includes the coke can opening / closing device described in Embodiment 1, and also includes a running track 90, a lifting tower 100 or a coke quenching car 110. The running track 90 is connected to the entrance of the lifting tower 100 or the coke quenching car 110. The fixing frame 10 is set at the entrance of the lifting tower 100 or the coke quenching car 110. The transport vehicle 30 is set on the running track 90 and can move along the running track 90 to pass the fixing frame 10 and enter the lifting tower 100 or the coke quenching car 110.

[0042] The running track 90 precisely aligns with the entrance of the lifting tower 100 or the coke quenching car 110, ensuring the smooth entry of the transport vehicle 30 into the equipment. The fixed frame 10 is fixedly installed at the entrance of the lifting tower 100 or the coke quenching car 110, reinforced by a ground foundation, and positioned corresponding to the running track 90. ​​This ensures that the transport vehicle 30 can complete the lifting / covering operation when passing the fixed frame 10 without affecting the normal operation of the equipment. The transport vehicle 30 is positioned on the running track 90 and can move freely along the track. After completing the lifting / covering action at the fixed frame 10, it smoothly enters the lifting tower 100 or the coke quenching car 110 to complete the coke transfer, lifting, or coke loading processes.

[0043] Taking the lifting tower 100 as an example, the transport vehicle 30 carries the coke can 70 filled with coke and travels along the running track 90 towards the lifting tower 100. When it passes the fixed frame 10 at the entrance, the lid is opened by the lid-closing device and the can lid 40 is attached to the fixed frame 10. After the transport vehicle enters the lifting tower 100, the lifting tower 100 lifts the coke can 70 to the unloading process. After unloading is completed, the transport vehicle 30 travels in the opposite direction along the track. When it passes the fixed frame 10, the lid-closing device closes the lid and the can lid 40 covers the coke can 70 again. The transport vehicle then moves to the next loading point, forming a closed loop operation.

[0044] Preferably, the coking production system includes a lifting tower 100 and a coke quenching car 110. The coke can opening / closing device includes two devices, with two fixed frames 10 respectively installed at the entrances of the lifting tower 100 and the coke quenching car 110. The slopes 211 on the two fixed frames 10 have opposite inclination directions. Two lifting mechanisms 60 are installed on opposite sides of the transport vehicle 30, and two hanging ears 80 are installed on opposite sides of the can cover 40.

[0045] In this embodiment, the coking production system includes a lifting tower 100, a coke quenching car 110, and two sets of coke can opening / closing devices. The two sets of covering devices have the same structure, except that the inclination direction of the ramp 211 on the fixed frame 10 is opposite, which is adapted to the bidirectional operation requirements. The specific settings are as follows: the two sets of fixed frames 10 are fixed at the entrances of the lifting tower 100 and the coke quenching car 110, respectively, and are precisely aligned with the entrances and running tracks 90 of the corresponding equipment; the first set of fixed frames 10 corresponds to the entrance of the coke quenching car 110, and its fork 21 ramp 211 increases in the first direction along the direction in which the transport vehicle 30 enters the coke quenching car 110; the second set of fixed frames 10 corresponds to the entrance of the lifting tower 100, and its fork 21 ramp 211 increases in the opposite direction to the first direction along the direction in which the transport vehicle 30 enters the lifting tower 100. The reverse design of the ramp 211 is adapted to the bidirectional operation of the transport vehicle. Two lifting mechanisms 60 are installed on opposite sides of the frame of the transport vehicle 30, spaced apart from the coke tank 70, and both adopt a hydraulic lifting rod structure; two lugs 80 are installed on opposite sides of the tank cover 40, corresponding one-to-one with the two lifting mechanisms 60, and the notches 82 of the lugs 80 are respectively opened on the side of the corresponding driving direction to ensure smooth connection of the lifting end.

[0046] See attached document Figure 11 As shown, the complete workflow is as follows: The carrier vehicle 30 travels unloaded from left to right along the running track 90 toward the coke quenching car 110. When it passes the fixed frame 10 at the entrance of the coke quenching car 110, it completes the opening action through the lifting mechanism 60 on the left side, and then the lifting mechanism 60 retracts to avoid the hanging ear 80 on the right side. The transport vehicle enters the coke quenching car 110, and the coke quenching car 110 loads coke into the coke can 70. After loading, the transport vehicle travels along the track from right to left towards the lifting tower 100. When it passes the fixed frame 10 at the entrance of the coke quenching car 110, the lifting mechanism 60 on the left side performs the capping action. After the can lid 40 is capped, the lifting mechanism 60 on the left side retracts. After the coke is loaded, the transport vehicle continues to travel along the track from right to left toward the lifting tower 100. When it passes the fixed frame 10 at the entrance of the lifting tower 100, the right lifting mechanism 60 raises to complete the opening action. After the can cover 40 is hooked onto the fixed frame 10 at the entrance of the lifting tower 100, the right lifting mechanism 60 retracts to avoid the left hanging lug 80. After the transport vehicle enters the lifting tower 100, the coke tank 70 is lifted and unloaded. The transport vehicle travels along the track from left to right. When it passes the fixed frame 10 at the entrance of the lifting tower 100, the right lifting mechanism 60 is raised. After the tank cover 40 is put on, the right lifting mechanism 60 is retracted. The transport vehicle continues to travel along the track from left to right, moving out of the fixed frame 10 at the entrance of the lifting tower 100, waiting for the next round of coking, forming a closed-loop operation of the entire process.

[0047] Beneficial effects: The bidirectional adaptability design of the two sets of capping devices enables fully automated capping / uncapping of the transport vehicle 30 during the transfer process between the coke quenching car 110 and the lifting tower 100, without manual intervention, significantly improving production efficiency; no adjustment to the transport vehicle structure and driving trajectory is required, and bidirectional operation can be adapted simply by the reverse design of the ramp 211 and the layout of the double-sided lifting mechanism 60 and the hanging ear 80, resulting in low modification costs and strong versatility; the full capping and sealing reduces coke heat loss and fugitive dust emissions, resulting in significant environmental protection and energy-saving effects; the two sets of devices work independently yet in coordination, ensuring high equipment reliability and adapting to the needs of large-scale continuous coking production.

[0048] Preferably, the projections of the lugs 80 on both sides of the can lid 40 along the running direction of the transport vehicle 30 are separated from each other. Correspondingly, the projections of the lifting mechanism 60 on each side and the lugs 80 on the opposite side along the running direction of the transport vehicle 30 are separated from each other, so that the lifting mechanism 60 on each side does not interfere with the lugs on the opposite side when it moves with the transport vehicle.

[0049] Based on the above structure, the complete workflow is as follows: 1. The unloaded transport vehicle 30 travels from left to right along the running track 90 towards the coke quenching car 110. When it passes the fixed frame 10 at the entrance of the coke quenching car 110, the lifting mechanism 60 on the left side completes the opening action. The lid 40 is suspended on the fixed frame 10. When the lifting mechanism 60 on the left side passes the two hanging ears 80 on the right side, the lifting mechanism 60 on the left side does not need to retract. The transport vehicle 30 can pass through the fixed frame 10 and smoothly pass the lid 40 before entering the coke quenching car 110. 2. After the transport vehicle enters the coke quenching car 110, the coke quenching car 110 loads coke into the coke can 70. After loading, the transport vehicle travels along the track from right to left towards the lifting tower 100. When it passes the fixed frame 10 at the entrance of the coke quenching car 110, it completes the covering action through the lifting mechanism 60 raised on the left, and then the lifting mechanism 60 on the left retracts. 3. After the coke is loaded, the transport vehicle continues to travel along the track from right to left toward the lifting tower 100. At this time, when it passes the fixed frame 10 at the entrance of the lifting tower 100, the right lifting mechanism 60 rises to complete the opening action, and the can cover 40 is hooked on the fixed frame 10 at the entrance of the lifting tower 100. Similarly, the lifting mechanism 60 can enter the lifting tower 100 without retracting. 4. After the transport vehicle enters the lifting tower 100, the coke tank 70 is lifted and unloaded. The transport vehicle travels along the track from left to right. When it passes the fixed frame 10 at the entrance of the lifting tower 100, the lid 40 is put on by the lifting mechanism 60 raised on the right side. Then the lifting mechanism 60 on the right side retracts. 5. The transport vehicle continues to travel along the track from left to right to the fixed frame 10 at the entrance of the lifting tower 100, waiting for the next round of coking, forming a closed-loop operation of the entire process.
