Description

Technical Field

[0001] This invention relates to the field of coke oven technology, and in particular to a coke oven switching device and a coke oven switching method. Background Technology

[0002] As the core container that directly holds the red-hot coke in the dry quenching process, the coke can is in direct contact with the high-temperature red-hot coke for a long time, which makes it prone to damage such as inner wall wear, local deformation, and peeling of the high-temperature resistant layer. In order to ensure operational safety and the stability of coke transfer, the damaged coke can must be lifted out for repair in a timely manner, and a spare coke can must be replaced to maintain continuous production. The resulting coke can replacement operation in dry quenching is a key link in the dry quenching process.

[0003] In actual coke can switching operations, manual stabilization and alignment of the coke cans are required during hoisting. However, in dry quenching scenarios, the coke cans still retain high temperatures after leaving the high-temperature working environment. Close-range manual operation not only poses risks to personal safety due to accidental collisions and can shake, but also suffers from low alignment efficiency and insufficient positioning accuracy, leading to prolonged coke can switching operation cycles and impacting overall production efficiency. Furthermore, in the current switching process, damaged coke cans must first be disassembled from the operating system and then transported to a separate inspection area to determine the extent of their internal damage. This not only increases additional transportation and disassembly costs but also prolongs the coke can maintenance cycle, affecting the coke can recycling rate and further hindering the efficient advancement of the dry quenching process. Summary of the Invention

[0004] The purpose of this invention is to provide a coke can switching device and a coke can switching method, so as to realize automatic alignment and precise positioning of coke cans during hoisting, improve the safety of coke can hoisting process, and at the same time, detect the old coke cans during the switching process between new and old coke cans, thereby improving the recycling rate of coke cans.

[0005] To achieve this objective, the technical solution adopted by the present invention is as follows: A coke can switching device includes two transfer trolleys, each trolley having a body and wheels disposed at the bottom of the body, the bodies of the two transfer trolleys being connected; when one of the transfer trolleys moves to a first position, a new coke can is hoisted onto the body located at the first position; when the other transfer trolley moves to a second position, an old coke can is hoisted onto the body located at the second position; The transfer trolley also includes: The locking mechanism includes a locking drive and two limiting components. The two limiting components are spaced apart and movably disposed on the vehicle body along the width direction. The locking drive is convexly connected to the two limiting components so that the two limiting components move away from each other along the width direction and the limiting components lock the wheel; or, the two limiting components move closer to each other along the width direction and limit and clamp the old coke canister or the new coke canister, and the limiting components simultaneously unlock the wheel. A repositioning mechanism is provided on the vehicle body. The repositioning mechanism slides with the new coke canister or the old coke canister to guide the new coke canister or the old coke canister to be hoisted onto the vehicle body. The testing facility is located on the vehicle body that carries the old coke canister.

[0006] As an optional solution, the locking mechanism further includes a lifting frame, which has convex shafts at both ends along the width direction. The output end of the locking drive is connected to the lifting frame to drive the lifting frame to descend along the height direction to the parking position to lock the wheel or to rise to the driving position to unlock the wheel. The limiting component includes a column and a limiting frame. The limiting frame is slidably disposed on the vehicle body along the width direction and has a locking position that abuts against the new coke can or the old coke can and an unlocking position that moves away from the new coke can or the old coke can. The column is movably disposed on the vehicle body and is drivenly connected to the corresponding limiting frame. A guide groove is provided on the outer periphery of the column, and the convex shaft is slidably disposed in the corresponding guide groove. When the lifting frame descends to the parking position, the convex shaft slides downward along the guide groove to drive the column to rotate around the axis and drive the limit frame to move to the unlock position through the column; when the lifting frame rises to the driving position, the convex shaft slides upward along the guide groove to drive the column to rotate around the axis and drive the limit frame to move to the locking position through the column.

[0007] As an optional solution, the limiting assembly further includes a first link, a second link, and a third link that are slidably connected in sequence. The end of the first link away from the second link is rotatably connected to the corresponding column, and the end of the third link away from the second link is rotatably connected to the corresponding limiting frame.

[0008] As an optional solution, the bottom end of the vehicle body is rotatably provided with an axle, both ends of the axle are equipped with wheels, and the axle is also equipped with a locking cylinder, the locking cylinder being provided with multiple locking holes spaced apart along the circumference; When the lifting frame descends to the parking position, the bottom end of the lifting frame is selectively inserted into one of the locking holes to lock the wheel; when the lifting frame rises to the driving position, the bottom end of the lifting frame disengages from the corresponding locking hole to unlock the wheel.

[0009] As an optional solution, the repositioning mechanism includes two repositioning components, which are spaced apart along the width direction and disposed opposite to each other on the vehicle body; the repositioning components include: A return bracket is installed on the vehicle body; The repositioning plate is provided with at least two repositioning protrusions, and a repositioning channel is formed between the at least two repositioning protrusions to slide with the old coke tank or the new coke tank; the repositioning plate is rotatably mounted on the repositioning bracket and has a clearance position away from the old coke tank or the new coke tank and a hoisting position to slide against the support rib of the old coke tank or the new coke tank. The return drive and reset component are configured to drive the return plate to rotate to the avoidance position and drive the return plate toward the hoisting position.

[0010] As an optional solution, the vehicle body is provided with a support plate, which is used to support the old coke can or the new coke can; The bearing plate is provided with a return groove, and the supporting rib is slidably disposed in the return groove.

[0011] As an optional solution, the transfer trolley further includes a lifting mechanism, which includes: A lifting drive component is disposed on the vehicle body that carries the new coke can; A lifting frame is installed on the vehicle body; when the vehicle body carrying the new coke can moves to the second position, the lifting drive unit drives the lifting frame to rise, so that the lifting frame supports the new coke can and rises synchronously.

[0012] As an optional solution, the testing institution includes: A detection drive assembly is disposed on the vehicle body that carries the old coke canister; A rangefinder is used to measure the inner wall of the old coke canister; the output end of the detection drive assembly is provided with the rangefinder so that the rangefinder extends into or out of the old coke canister and adjusts the position of the rangefinder inside the old coke canister.

[0013] The coke can switching method is applied to the coke can switching device described above, wherein the car body carrying the old coke can is the first car body, and the car body carrying the new coke can is the second car body; The coke pot switching method includes the following steps: S1: The second vehicle body moves to the first position. In the second vehicle body, the locking drive causes the two limiting components to move away from each other in the width direction, and the limiting components lock the wheels. The new coke can is hoisted above the second vehicle body. The new coke can is lowered and slides with the return mechanism to guide the new coke can to be hoisted to the second vehicle body. S2: The first vehicle body moves to the second position. In the first vehicle body, the locking drive causes the two limiting components to move away from each other in the width direction, and the limiting components lock the wheels. The old coke canister is removed from the working position and hoisted above the first vehicle body. The old coke canister is lowered and slides with the return mechanism to guide the old coke canister to be hoisted to the first vehicle body. S3: The detection mechanism of the first vehicle body detects the old coke canister; S4: The second vehicle body moves to the second position. In the second vehicle body, the locking drive drives the two limiting components to move away from each other in the width direction, and the limiting components lock the wheels; the new coke tank located in the second vehicle body is hoisted to the working position.

[0014] As an optional solution, the transfer trolley further includes a lifting mechanism, which includes a lifting drive and a lifting frame. The lifting drive is disposed on the vehicle body that carries the new coke can; the lifting frame is disposed on the vehicle body. In step S4, when hoisting the new coke can, the lifting drive unit drives the lifting frame to rise, so that the lifting frame supports the new coke can and rises synchronously.

[0015] The beneficial effects of this invention are as follows: The coke can switching device proposed in this invention, when a new coke can is hoisted onto a car body located at the first position, a locking mechanism drives two limiting components to move away from each other along the width direction to facilitate the hoisting of the new coke can. Simultaneously, the limiting components lock the wheels, ensuring that one car body is stably held in the first position, guaranteeing precise alignment between the new coke can and the car body at the first position. When an old coke can is hoisted onto a car body located at the second position, the locking mechanism drives the two limiting components to move away from each other along the width direction to facilitate the hoisting of the old coke can. Simultaneously, the limiting components lock the wheels, ensuring that the other car body is stably held in the second position, guaranteeing precise alignment between the old coke can and the car body at the second position. The new and old coke cans slide into the corresponding car body's return mechanism, respectively, and are hoisted onto different car bodies under the guidance of the return mechanism. No manual alignment is required during the hoisting process, achieving automatic swinging and precise alignment of the new and old coke cans during hoisting, thus improving the safety of the coke can hoisting process.

[0016] In addition, during the replacement of new coke cans with old ones, the old coke cans are inspected by an inspection agency, which saves working time and helps to improve the recycling rate of coke cans.

[0017] The coke can replacement method proposed in this invention is applied to the aforementioned coke can replacement device, realizing automatic swinging and precise alignment of the new and old coke cans during the hoisting process, thus improving the safety of the coke can hoisting process. By using an inspection mechanism to inspect the old coke cans, working time is saved, which is beneficial to improving the recycling rate of the coke cans. Attached Figure Description

[0020] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Furthermore, it should be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, not all of them.

Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1 As the core container that directly holds the red-hot coke in the dry quenching process, the coke can is in direct contact with the high-temperature red-hot coke for a long time, which makes it prone to damage such as inner wall wear, local deformation, and peeling of the high-temperature resistant layer. In order to ensure operational safety and the stability of coke transfer, the damaged coke can must be lifted out for repair in a timely manner, and a spare coke can must be replaced to maintain continuous production. The resulting coke can replacement operation in dry quenching is a key link in the dry quenching process.

[0026] like Figure 1 As shown, the coke tank includes a main tank body 300 and supporting stiffeners 400. The bottom end of the main tank body 300 is conical and rests on a base plate. An overlapping plate is fitted around the outer periphery of the main tank body 300 to facilitate the placement and installation of the coke tank. Multiple supporting stiffeners 400 are spaced apart between the base plate and the overlapping plate along the circumference of the coke tank.

[0027] In actual coke can switching operations, manual stabilization and alignment of the coke cans are required during hoisting. However, in dry quenching scenarios, the coke cans still retain high temperatures after leaving the high-temperature working environment. Close-range manual operation not only poses risks to personal safety due to accidental collisions and can shake, but also suffers from low alignment efficiency and insufficient positioning accuracy, leading to prolonged coke can switching operation cycles and impacting overall production efficiency. Furthermore, in the current switching process, damaged coke cans must first be disassembled from the operating system and then transported to a separate inspection area to determine the extent of their internal damage. This not only increases additional transportation and disassembly costs but also prolongs the coke can maintenance cycle, affecting the coke can recycling rate and further hindering the efficient advancement of the dry quenching process.

[0028] To solve the above problems, such as Figures 2-4As shown, this embodiment proposes a coke can switching device, which includes two transfer trolleys 1. Each transfer trolley 1 includes a body 11 and wheels 12 disposed at the bottom of the body 11. The bodies 11 of the two transfer trolleys 1 are connected. When one transfer trolley 1 moves to a first position, a new coke can 100 is hoisted onto the body 11 located at the first position. When the other transfer trolley 1 moves to a second position, an old coke can 200 is hoisted onto the body 11 located at the second position. The transfer trolley 1 also includes a locking mechanism 2, a repositioning mechanism 3, and a detection mechanism 4. The locking mechanism 2 includes a locking drive component 21 and two limiting components. The two limiting components are spaced apart and movably mounted on the trolley body 11 along the width direction (left-right direction in the figure). The locking drive component 21 is drive-connected to the two limiting components, causing the two limiting components to move away from each other along the width direction, and locking the wheels 12; alternatively, the two limiting components move closer to each other along the width direction and clamp the old coke canister 200 or the new coke canister 100, while simultaneously unlocking the wheels 12. The repositioning mechanism 3 is mounted on the trolley body 11 and slides with the new coke canister 100 or the old coke canister 200 to guide the new coke canister 100 or the old coke canister 200 to be hoisted onto the trolley body 11. The detection mechanism 4 is mounted on the trolley body 11 that carries the old coke canister 200.

[0029] When the new coke canister 100 is hoisted onto the car body 11 at the first position, the locking mechanism 2 drives the two limiting components to move away from each other along the width direction to facilitate the hoisting of the new coke canister 100. Simultaneously, the limiting components lock the wheels 12, ensuring that one of the car bodies 11 is stably held in the first position, thus guaranteeing precise alignment between the new coke canister 100 and the car body 11 at the first position. When the old coke canister 200 is hoisted onto the car body 11 at the second position, the locking mechanism 2 drives the two limiting components to move away from each other along the width direction to facilitate the hoisting of the old coke canister 200. Simultaneously, the limiting components lock the wheels 12, ensuring that the other car body 11 is stably held in the second position, thus guaranteeing precise alignment between the old coke canister 200 and the car body 11 at the second position. The new coke canister 100 and the old coke canister 200 are respectively slidably engaged with the return mechanism 3 of the corresponding car body 11, so that they are hoisted to different car bodies 11 under the guidance of the return mechanism 3. No manual alignment is required during the hoisting process, realizing the automatic swing and precise alignment of the new coke canister 100 and the old coke canister 200 during the hoisting process, which improves the safety of the coke canister hoisting process.

[0030] In addition, during the replacement of the new coke canister 100 with the old coke canister 200, the old coke canister 200 is inspected by the inspection agency 4, which saves working time and helps to improve the recycling rate of the coke canister.

[0031] like Figure 2As shown, the bodies 11 of two transfer trolleys 1 are connected, and each body 11 has an axle 13 rotatably mounted at its bottom end. Wheels 12 are mounted at both ends of each axle 13. Specifically, each body 11 has two axles 13 spaced apart along its length (front-back direction in the figure) at its bottom end, allowing the bottom end of the body 11 to move via four wheels 12. Since the transfer trolley 1 is a mature existing technology, the drive and control components required for the transfer trolley 1 to travel and steer via the wheels 12 will not be described in detail.

[0032] like Figures 3-5 As shown, the locking mechanism 2 also includes a lifting frame 22. Both ends of the lifting frame 22 along the width direction are provided with convex shafts 221. The output end of the locking drive member 21 is connected to the lifting frame 22 to drive the lifting frame 22 to descend along the height direction (up and down direction in the figure) to the parking position of the locked wheel 12 or to rise to the driving position of the unlocked wheel 12. The limiting assembly includes a column 23 and a limiting frame 24. The limiting frame 24 is slidably disposed on the vehicle body 11 along the width direction and has a locking position that abuts against the new coke tank 100 or the old coke tank 200 and an unlocking position that moves away from the new coke tank 100 or the old coke tank 200. The column 23 is movably disposed on the vehicle body 11 and is connected to the corresponding limiting frame 24 via a transmission. A guide groove 231 is provided on the outer periphery of the column 23, and the convex shafts 221 are slidably disposed within the corresponding guide grooves 231. When the lifting frame 22 is lowered to the parking position, the cam shaft 221 slides downward along the guide groove 231 to drive the column 23 to rotate around the axis and drive the limit frame 24 to move to the unlock position through the column 23; when the lifting frame 22 is raised to the driving position, the cam shaft 221 slides upward along the guide groove 231 to drive the column 23 to rotate around the axis and drive the limit frame 24 to move to the locked position through the column 23.

[0033] The aforementioned locking drive component 21 is a motor. Each vehicle body 11 has two locking mechanisms 2 spaced along its length to limit and fix the new coke canister 100 or the old coke canister 200, improving the stability of the new or old coke canister 100 within its respective vehicle body 11. Each locking mechanism 2 includes a lifting frame 22, two columns 23, and two limiting members, with each column 23 and limiting member connected in a one-to-one transmission connection. When hoisting the new coke canister 100 or the old coke canister 200, the locking drive component 21 of the corresponding vehicle body 11 drives the lifting frame 22 to descend, moving the lifting frame 22 to the parking position to lock the wheels 12. This fixes the coke canister swapping device in the first or second position, facilitating precise alignment of the new or old coke canister 100 with the corresponding vehicle body 11 during hoisting. The lifting frame 22 is slidably engaged with the guide grooves 231 of the two columns 23 via two convex shafts 221, so that the lifting frame 22 drives the two columns 23 to rotate around the axial direction. The two columns 23 drive the corresponding limiting frames 24 to move away in the width direction, so as to provide installation space for the new coke can 100 and the old coke can 200 and avoid interference between the new coke can 100 and the old coke can 200 and the limiting frames 24. After the new coke can 100 or the old coke can 200 is hoisted, the locking drive component 21 of the corresponding car body 11 drives the lifting frame 22 to rise, so that the lifting frame 22 moves to the driving position to unlock the wheels 12, that is, the coke can changing device can move to the next position. The lifting frame 22 slides with the guide grooves 231 of the two columns 23 through two convex shafts 221, so that the lifting frame 22 drives the two columns 23 to rotate around the axis (the rotation direction is opposite to the rotation direction of the columns 23 when the lifting frame 22 descends). The two columns 23 drive the corresponding limiting frames 24 to move closer to each other along the width direction, so as to limit and clamp the new coke tank 100 and the old coke tank 200, thereby improving the stability of the new coke tank 100 or the old coke tank 200 in their respective car bodies 11.

[0034] It should be noted that each limiting frame 24 has an upwardly extending limiting rod, which can abut against the support rib plate 400 of the coke can, thereby clamping the coke can together through multiple limiting rods. The guide groove 231 in the column 23 is formed by a vertical groove and a spiral groove smoothly connected, with the vertical groove located above the spiral groove. Guide grooves are provided on the car body 11 along the width direction, and a guide block is correspondingly provided at the bottom of each limiting frame 24. The guide block and the guide groove slide in a one-to-one correspondence to guide and limit the movement of the limiting frame 24 along the width direction, thereby improving the movement accuracy and stability of the limiting frame 24 along the width direction.

[0035] like Figure 3As shown, the axle 13 is also equipped with a locking cylinder 14, which has multiple locking holes 141 spaced circumferentially. When the lifting frame 22 is lowered to the parking position, the bottom end of the lifting frame 22 selectively inserts into one of the locking holes 141 to lock the wheel 12; when the lifting frame 22 is raised to the driving position, the bottom end of the lifting frame 22 disengages from the corresponding locking hole 141 to unlock the wheel 12. Through the insertion and engagement of the lifting frame 22 with the locking holes 141 of the locking cylinder 14, the locking cylinder 14 can be locked, thereby restricting the rotation of the axle 13 and ensuring that the vehicle body 11 remains in the parking state.

[0036] like Figure 4 As shown, the limiting assembly also includes a first link 25, a second link 26, and a third link 27 that are slidably connected in sequence. The end of the first link 25 away from the second link 26 is rotatably connected to the corresponding column 23, and the end of the third link 27 away from the second link 26 is rotatably connected to the corresponding limiting frame 24. The first link 25, the second link 26, and the third link 27 form a telescopic linkage assembly, which allows the column 23 to drive the limiting frame 24 to move in the width direction to a locked position or an unlocked position via the linkage assembly.

[0037] like Figure 6 and Figure 7 As shown, the repositioning mechanism 3 includes two repositioning components, which are spaced apart and opposite to each other on the vehicle body 11 along the width direction. Each repositioning component includes a repositioning bracket 31, a repositioning plate 32, a repositioning drive, and a resetting component 34. The repositioning bracket 31 is disposed on the vehicle body 11. The repositioning plate 32 is provided with at least two repositioning protrusions 33, forming a repositioning channel between the at least two repositioning protrusions 33 that slides into the old coke tank 200 or the new coke tank 100. The repositioning plate 32 is rotatably mounted on the repositioning bracket 31 and has a clearance position away from the old coke tank 200 or the new coke tank 100 and a lifting position that slides against the support ribs 400 of the old coke tank 200 or the new coke tank 100. The repositioning drive drives the repositioning plate 32 to rotate to the clearance position, and the resetting component 34 is configured to drive the repositioning plate 32 to move toward the lifting position.

[0038] Specifically, the repositioning mechanism 3 also includes a repositioning drive component and a repositioning shaft 35. The repositioning drive component is mounted on the repositioning bracket 31 and can be a motor, cylinder, etc. The repositioning plate 32 is rotatably mounted on the repositioning bracket 31 via the repositioning shaft 35. The reset component 34 is a torsion spring, which is sleeved and mounted on the repositioning shaft 35. The repositioning drive component drives the repositioning plate 32 to rotate relative to the repositioning bracket 31. Positioning blocks 311 are provided on the inner sides of both repositioning brackets 31. When the coke can is hoisted, the return drive unit drives the corresponding return plate 32 to flip downward and abut against the positioning block 311. At this time, the return plate 32 is set in the vertical direction to avoid interference with the coke can. When the coke can is hoisted from top to bottom to the corresponding car body 11, the return drive unit disconnects the transmission connection with the return plate 32. Under the action of the reset member 34, the return plate 32 flips upward to the inclined hoisting position so that the support rib plate 400 of the coke can slide into the return channel formed between the two return protrusions 33. Under the guiding and limiting action of the return channel, the coke can is automatically aligned.

[0039] like Figure 7 As shown, the positioning protrusion 33 in this embodiment consists of an inclined block and a vertical block connected together. The inclined block is located on the upper side of the vertical block. The distance between the two vertical blocks is adapted to the support rib plate 400. The distance between the two inclined blocks gradually increases in the direction away from the vertical block to form a guide flare. This allows the support rib plate 400 of the coke can to quickly enter the positioning channel through the guide flare, thereby achieving the alignment of the coke can without manual intervention. This quickly completes the coke can positioning process, improves the efficiency of hoisting the coke can, avoids injury to construction personnel from swaying coke cans, and improves the reliability and safety of the coke can replacement process.

[0040] like Figure 6 and Figure 8 As shown, the vehicle body 11 is equipped with a support plate 15, which is used to support the old coke can 200 or the new coke can 100. The support plate 15 is provided with a return groove 150, and the support rib 400 is slidably disposed in the return groove 150. By providing the return groove 150, the support rib 400 is limited in the height direction to prevent the coke can from circumferentially shaking.

[0041] Furthermore, the support plate 15 is provided with two return grooves 150. Multiple first fixing rods 151 are spaced apart at the bottom end of the support plate 15, each extending along the height direction. A limiting groove communicating with the return groove 150 is formed between two adjacent first fixing rods 151 below each return groove 150, further limiting the support rib 400 along the height direction. It is understood that in other embodiments, the support plate 15 may also be provided with one or more return grooves 150.

[0042] like Figure 9As shown, when the coke can is hoisted to the corresponding vehicle body 11, a portion of the coke can's supporting rib plate 400 is located within the limiting groove formed between two adjacent first fixing rods 151. One limiting rod of the limiting frame 24 is correspondingly slidably disposed within the corresponding limiting groove, so that the limiting rod can press against the coke can's supporting rib plate 400, thereby clamping the coke can together through the limiting rods. At the same time, the limiting groove guides and limits the movement of the limiting frame 24 in the width direction, further improving the movement accuracy and stability of the limiting frame 24 in the width direction.

[0043] like Figure 10 As shown, the transfer trolley 1 also includes a lifting mechanism 5, which includes a lifting drive 51 and a lifting frame 52. The lifting drive 51 is disposed on the vehicle body 11 carrying the new coke can 100. The lifting frame 52 is disposed on the vehicle body 11. When the vehicle body 11 carrying the new coke can 100 moves to the second position, the lifting drive 51 drives the lifting frame 52 to rise, so that the lifting frame 52 supports the new coke can 100 and rises synchronously. In this embodiment, the lifting mechanism 5 includes two lifting motors or two lifting cylinders, etc., to lift the new coke can 100 off the vehicle body 11 by the lifting frame 52. By raising the new coke can 100 through the lifting mechanism 5, the lifting equipment can perform lifting operations on the new coke can 100, thus improving the lifting efficiency. It is understood that the lifting height of the new coke can 100 by the lifting mechanism 5 can be flexibly adjusted according to the lifting requirements of the on-site lifting equipment, and no specific limitation is made here.

[0044] like Figure 2 , Figure 6 and Figure 11 As shown, the detection mechanism 4 includes a detection drive assembly and a rangefinder 41. The detection drive assembly is mounted on the vehicle body 11 that carries the used coke canister 200. The rangefinder 41 is used to measure the inner wall of the used coke canister 200. The output end of the detection drive assembly is equipped with the rangefinder 41, allowing the rangefinder 41 to extend into or out of the used coke canister 200 and adjust its position within the canister. The rangefinder 41 is used to measure the dimensions (inner diameter) of the inner wall of the replaced used coke canister 200, thereby detecting the degree of damage to the inner wall of the used coke canister 200. Since the process of damage detection of the used coke canister 200 using the rangefinder 41 is a mature existing technology, it will not be described in detail here.

[0045] Specifically, the detection drive assembly includes a first detection motor 42, a turntable 43, a connecting block 44, a second detection motor 45, a rotating block 46, a third detection motor 47, and a fourth detection motor 48. A gantry is mounted on the vehicle body 11. The first detection motor 42 is mounted on the gantry, and its output is connected to the turntable 43 and the connecting block 44 to drive them to rotate. The connecting block 44 is mounted on the second detection motor 45, and its output is connected to the rotating block 46. The third detection motor 47 is mounted on the rotating block 46, and its output is connected to the fourth detection motor 48. The output of the fourth detection motor 48 is connected to a rangefinder 41.

[0046] Before the old coke canister 200 is hoisted to the corresponding vehicle body 11, the second detection motor 45 drives the rotating block 46 to rotate so that the third detection motor 47 and the fourth detection motor 48 are set in a horizontal direction. The first detection motor 42 drives the turntable 43 to rotate so that the rotating block 46, the third detection motor 47, the fourth detection motor 48 and the rangefinder 41 are away from the area on the vehicle body 11 where the old coke canister 200 is placed, so as to avoid interference when the old coke canister 200 is hoisted. Once the used coke canister 200 is hoisted onto the corresponding vehicle body 11 and the limiting components clamp it in place, the first detection motor 42 drives the turntable 43 to rotate, causing the rotating block 46, the third detection motor 47, the fourth detection motor 48, and the rangefinder 41 to rotate directly above the used coke canister 200 on the vehicle body 11. The second detection motor 45 then drives the rotating block 46 to rotate, causing the third detection motor 47 and the fourth detection motor 48 to be vertically aligned, allowing the rangefinder 41 to extend into the main tank body 300 of the used coke canister 200. The second detection motor 45 adjusts the attitude of the rangefinder 41 within the main tank body 300 of the used coke canister 200; the third detection motor 47 moves the rangefinder 41 up and down in the height direction; and the fourth detection motor 48 rotates the rangefinder 41 axially. Therefore, the position of the rangefinder 41 within the main tank 300 of the old coke tank 200 can be flexibly adjusted according to the actual inspection requirements of the old coke tank 200 through the inspection drive component, thereby improving the inspection efficiency of the old coke tank 200.

[0047] Example 2 like Figure 12 As shown, this embodiment proposes a coke can replacement method, which is applied to the coke can replacement device in Embodiment 1. For ease of description, the car body 11 carrying the old coke can 200 is defined as the first car body 11, and the car body 11 carrying the new coke can 100 is defined as the second car body 11. The specific configuration of the coke can replacement device can be referred to Embodiment 1, and will not be repeated here.

[0048] The coke pot switching method includes the following steps: S1: The second vehicle body 11 moves to the first position. In the second vehicle body 11, the locking drive 21 drives the two limiting components to move away from each other in the width direction, and the limiting components lock the wheels 12. The new coke canister 100 is hoisted to the top of the second vehicle body 11. The new coke canister 100 descends and slides with the return mechanism 3 to guide the new coke canister 100 to be hoisted to the second vehicle body 11.

[0049] S2: The first vehicle body 11 moves to the second position. In the first vehicle body 11, the locking drive 21 drives the two limiting components to move away from each other in the width direction, and the limiting components lock the wheels 12. The old coke canister 200 is removed from the working position and hoisted to the top of the first vehicle body 11. The old coke canister 200 is lowered and slides with the return mechanism 3 to guide the old coke canister 200 to be hoisted to the first vehicle body 11.

[0050] S3: The inspection mechanism 4 of the first car body 11 inspects the old coke tank 200.

[0051] S4: The second vehicle body 11 moves to the second position. In the second vehicle body 11, the locking drive 21 drives the two limiting components to move away from each other in the width direction, and the limiting components lock the wheels 12; the new coke tank 100 located in the second vehicle body 11 is hoisted to the working position.

[0052] When the new coke canister 100 is hoisted onto the car body 11 at the first position, the locking mechanism 2 drives the two limiting components to move away from each other along the width direction to facilitate the hoisting of the new coke canister 100. Simultaneously, the limiting components lock the wheels 12, ensuring that one of the car bodies 11 is stably held in the first position, thus guaranteeing precise alignment between the new coke canister 100 and the car body 11 at the first position. When the old coke canister 200 is hoisted onto the car body 11 at the second position, the locking mechanism 2 drives the two limiting components to move away from each other along the width direction to facilitate the hoisting of the old coke canister 200. Simultaneously, the limiting components lock the wheels 12, ensuring that the other car body 11 is stably held in the second position, thus guaranteeing precise alignment between the old coke canister 200 and the car body 11 at the second position. The new coke canister 100 and the old coke canister 200 are respectively slidably engaged with the return mechanism 3 of the corresponding car body 11, so that they are hoisted to different car bodies 11 under the guidance of the return mechanism 3. No manual alignment is required during the hoisting process, realizing the automatic swing and precise alignment of the new coke canister 100 and the old coke canister 200 during the hoisting process, which improves the safety of the coke canister hoisting process.

[0053] In addition, during the replacement of the new coke canister 100 with the old coke canister 200, the old coke canister 200 is inspected by the inspection agency 4, which saves working time and helps to improve the recycling rate of the coke canister.

[0054] It should be noted that the transfer trolley 1 also includes a lifting mechanism 5, which includes a lifting drive component 51 and a lifting frame 52. The lifting drive component 51 is disposed on the vehicle body 11 that carries the new coke canister 100; the lifting frame 52 is disposed on the vehicle body 11. In step S4, when hoisting the new coke canister 100, the lifting drive component 51 drives the lifting frame 52 to rise, so that the lifting frame 52 supports the new coke canister 100 and rises synchronously. By raising the new coke canister 100 through the lifting mechanism 5, the lifting equipment can perform hoisting operations on the new coke canister 100, thereby improving hoisting efficiency.

[0055] The specific operating steps for the coke pot switching method are as follows: 1) Lifting the new coke canister 100. When the second car body 11 moves to the first position, the new coke canister 100 is lifted onto the second car body 11 using a lifting device. On the second car body 11, the locking drive 21 drives the lifting frame 22 to descend to the parking position. The bottom end of the lifting frame 22 is inserted into the locking hole 141 of the locking cylinder 14 on the corresponding axle 13 to lock the wheel 12. The lifting frame 22 slides downward along the guide groove 231 in the corresponding column 23 via two convex shafts 221. The column 23 rotates and drives the connected linkage assembly (first link 25, second link 26 and third link 27) to swing, so that the two limiting frames 24 arranged opposite each other in the width direction move away from each other. The return plate 32 is tilted and located in the lifting position under the action of the reset member 34. As the spreader gradually lowers the new coke canister 100 onto the second car body 11, the supporting stiffeners 400 of the new coke canister 100 slide into the return channel of the return plate 32, automatically aligning the new coke canister 100 in the position of the second car body 11, thus achieving automatic swinging and precise alignment of the new coke canister 100. The overlapping plate of the new coke canister 100 overlaps with the bearing plate 15, and some of the supporting stiffeners 400 pass through the interconnected return groove 150 and the limiting groove.

[0056] Finally, the return drive unit drives the return plate 32 to rotate to the avoidance position. At this time, the return plate 32 abuts against the positioning block 311 of the return bracket 31, and the return plate 32 remains vertical, which facilitates the lifting and replacement of the new coke tank 100 later. The locking drive unit 21 drives the lifting frame 22 to rise to the traveling position. The bottom end of the lifting frame 22 is pulled out from the locking hole 141 of the locking cylinder 14 on the corresponding axle 13 to unlock the wheel 12. The lifting frame 22 slides upward along the guide groove 231 in the corresponding column 23 through two convex shafts 221. The column 23 rotates and drives the connected linkage assembly to swing, so that the two limiting frames 24 set opposite each other in the width direction approach each other and limit and clamp the new coke tank 100.

[0057] 2) Lifting the old coke canister 200. When the first car body 11 moves to the second position, the old coke canister 200 to be replaced is removed from the working position and lifted above the first car body 11 by a lifting device. Then the operation process of the locking mechanism 2 and the return mechanism 3 on the first car body 11 is exactly the same as the operation process of the locking mechanism 2 and the return mechanism 3 on the second car body 11, and will not be described again here.

[0058] After the old coke tank 200 is hoisted, the detection drive assembly is activated, causing the rangefinder 41 to extend into the main tank body 300 of the old coke tank 200. According to the detection requirements, the position of the rangefinder 41 is flexibly adjusted via the detection drive assembly to detect the degree of damage to the inner wall of the old coke tank 200.

[0059] 3) Lifting the new tank. When the second vehicle body 11 moves to the second position, the new coke tank 100 is lifted onto the second vehicle body 11 using a lifting device. On the second vehicle body 11, the locking drive 21 drives the lifting frame 22 to descend to the parking position. The bottom end of the lifting frame 22 is inserted into the locking hole 141 of the locking cylinder 14 on the corresponding axle 13 to lock the wheel 12. The lifting frame 22 slides downward along the guide groove 231 in the corresponding column 23 via two convex shafts 221. The column 23 rotates and drives the connected linkage assembly to swing, so that the two limit frames 24, which are set opposite each other in the width direction, move away from each other to release the new coke tank 100. The lifting drive 51 drives the lifting frame 52 to rise, so that the lifting frame 52 supports the new coke tank 100 and rises synchronously. The lifting device lifts the raised new coke tank 100 to the working position.

[0060] Finally, the locking drive unit 21 raises the lifting frame 22 to the driving position, and the bottom end of the lifting frame 22 is pulled out from the locking hole 141 of the locking cylinder 14 on the corresponding axle 13 to unlock the wheel 12. The transfer trolley 1 then transports the old coke canister 200 to the maintenance position.
