Description

Technical Field

[0001] This application relates to the field of finishing mill exit technology, and in particular to a finishing mill exit transition guide table. Background Technology

[0002] The transition guide table at the exit of the finishing mill is a key connecting device on the hot-rolled steel plate production line. Its core function is to receive the high-temperature steel plates rolled by the finishing mill and smoothly transport them to the subsequent cold roller conveyor or finished product collection equipment. It directly affects the conveying accuracy, surface quality, and continuous operation efficiency of the entire production line.

[0003] Publication (Announcement) No.: CN210172195U provides a transition guide table for the exit of a finishing mill, belonging to the technical field of finishing mill exit structure. It includes a bracket positioned between the finishing mill exit and the laminar flow cooling roller table, and several liners horizontally positioned on the upper surface of the bracket. The upper surfaces of the liners are all coplanar with the upper surface of the finishing mill exit, and all liners are movably connected to the bracket. A water-cooling mechanism is provided below the liners for cooling them. The finishing mill exit transition guide table provided by this utility model has multiple liners on the upper surface of the bracket. The strip slides on the upper surface of the liners. The hardness of the liners is less than that of the strip, reducing scratches on the strip surface. A water-cooling mechanism is provided below the liners to cool them and prevent the raised edges from scratching the strip surface after deformation due to frictional heat. Since multiple liners are movably connected to the bracket, one or more liners can be directly disassembled and replaced if damaged, avoiding unnecessary waste from replacing the entire liner.

It includes a bracket positioned between the finishing mill exit and the laminar flow cooling roller table, and several liners horizontally positioned on the upper surface of the bracket. The upper surfaces of the liners are all coplanar with the upper surface of the finishing mill exit, and all liners are movably connected to the bracket. A water-cooling mechanism is provided below the liners for cooling them. The finishing mill exit transition guide table provided by this patent has multiple liners on the upper surface of the bracket. The strip slides on the upper surface of the liners. The hardness of the liners is less than that of the strip, reducing scratches on the strip surface. The water-cooling mechanism below the liners cools them, preventing the raised edges from scratching the strip surface after frictional heat deformation. Since multiple liners are movably connected to the bracket, damaged liners can be directly disassembled and replaced, avoiding unnecessary waste from replacing the entire liner.

[0005] In the existing technology, there is no automatic lubrication mechanism between the liner plate and the support structure of the bracket. Under long-term operation, the frictional resistance between the two is large, which not only increases the power loss of steel plate conveying, but also accelerates the wear of the liner plate and the support track, significantly shortening the service life of the equipment. In addition, high-temperature steel plates are prone to lateral displacement due to uneven force during the conveying process, and even derailment, which interferes with the normal operation of subsequent processes such as layer cooling and coiling. Utility Model Content

[0006] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the lack of an automatic lubrication mechanism between the liner plate and the bracket support structure, the large frictional resistance between the two under long-term operation, and the easy lateral displacement of high-temperature steel plates during the conveying process due to uneven force, or even derailment, which interferes with the normal operation of subsequent layer cooling, coiling and other processes. Therefore, a transition guide table for the exit of a finishing mill is proposed.

[0007] The technical solution provided in this application for a transition guide table at the exit of a finishing mill is as follows:

[0008] A transition guide table at the exit of a finishing mill, comprising:

[0009] The platform includes connecting blocks fixedly installed on both sides, with a water collection hopper connected to the bottom of both connecting blocks. Supports are provided on both the left and right sides of the bottom of the water collection hopper. A connecting pipe is installed at the bottom of the water collection hopper, and a valve is installed inside the connecting pipe. A water collection tank is fixedly installed at the bottom of the connecting pipe. The platform also includes:

[0010] Two sliding tracks are both set on the outer surface of the platform. Multiple liner plates are slidably connected on the sliding tracks. The multiple liner plates are connected in series by the same hinge to form a closed loop. A driving sprocket and a driven sprocket are rotatably installed inside the platform. The closed loop is wrapped around the outer circumference of the driving sprocket and the driven sprocket. Both the left and right ends of the platform are provided with connecting slots. The connecting slots connect the sliding track at the top of the platform with the return channel at the bottom of the platform. This allows the liner plates to travel along the sliding track from the top of the platform through one connecting slot to the bottom of the platform, and then return to the top of the platform through the other connecting slot, so as to realize the cyclical rotation of the liner plates.

[0011] The lubrication mechanism, located inside the connecting block on the right, is used to deliver lubricating medium to the sliding rail, reduce the frictional resistance between the liner and the sliding rail, and ensure that the steel plate can smoothly drive the liner to move by its own thrust.

[0012] The adjustment mechanism, located on the front and rear sides of the platform, is used to center and guide the steel plates passing through the platform, preventing the steel plates from deviating from the conveying trajectory.

[0013] The power mechanism, located on the lubrication mechanism, is used to convert the linear motion power of the lubrication mechanism into the driving power of the adjustment mechanism, so as to realize the linkage and synchronization of the lubrication action and the centering adjustment action.

[0014] Furthermore, the lubrication mechanism includes a hydraulic cylinder located on the left side inside the connecting block on the right side. A sealing plate is fixedly installed at the output end of the hydraulic cylinder. The sealing plate is slidably connected to the connecting block. The connecting block contains lubricating oil. An oil injection hole is opened at the top of the connecting block, and a one-way valve is installed in the oil injection hole.

[0015] Furthermore, two fixing slots are symmetrically opened on the top of the platform, and nozzles are fixedly connected inside the two fixing slots. An opening is opened on the left side inside the connecting block, and a diversion pipe is fixedly connected to the output end of the opening. The diversion pipe includes a main pipe and two branch pipes. The input end of the main pipe is sealed and connected to the opening, and the output ends of the two branch pipes are respectively sealed and fixedly connected to the two nozzles. A sensor is installed on the top of the platform.

[0016] Furthermore, the adjustment mechanism includes two grooves respectively opened on the front and rear sides of the platform, and an adjustment plate is rotatably connected in each of the two grooves. A rotating shaft is fixedly installed on the left end of each of the two adjustment plates.

[0017] Furthermore, gear 2 is fixedly installed on the outer surface of both rotating shafts, and gear 2 is meshed with rack 1, and rack 1 is slidably connected to the platform.

[0018] Furthermore, the platform has two rotating columns symmetrically connected to its front and rear sides. Cams are fixedly installed on the outer surfaces of the two rotating columns. Cam grooves are opened around the periphery of the two cams. Reciprocating rods are slidably connected in the two cam grooves. The ends of the two reciprocating rods that are far apart from each other are fixedly connected to two racks respectively.

[0019] Furthermore, the power mechanism includes two racks II fixedly connected to the left side wall of the sealing plate, each rack II being meshed with a gear I, each gear I having a rotating column fixedly mounted on it, and each rotating column being rotatably connected to the connecting block.

[0020] Furthermore, the bottom ends of both rotating columns extend through the connecting block into the interior of the platform, and sprockets two are fixedly installed on the outer surfaces of both rotating columns, and sprockets one are fixedly installed on the outer surfaces of both rotating columns. The same chain is meshed with sprockets one and two.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This solution uses a single hydraulic cylinder as the power source. Through a purely mechanical linkage structure of gears, sprockets, and cams, it simultaneously achieves precise lubrication of the sliding track and centering and guiding adjustment of the steel plate. It eliminates the need to configure multiple independent power sources for different functions, greatly simplifying the equipment structure and reducing the equipment failure rate, energy consumption, and subsequent maintenance costs.

[0023] 2. The annular closed-loop circulating liner structure of this solution, together with the return channel formed by the driving sprocket, driven sprocket and connecting groove inside the platform, realizes the circulation of the liner, avoids a single liner from being continuously subjected to the friction and baking of high temperature steel plate, effectively extends the service life of the liner, reduces the frequency of downtime to replace the liner, and significantly improves the continuous operation efficiency of the hot rolling production line.

[0024] 3. The adjustment mechanism of this solution adopts a non-clamping fine-tuning guide design. The adjustment plate corrects the deviation trajectory of the steel plate by only moving slightly closer, which will not hinder the steel plate conveying. This not only solves the technical problem of high temperature steel plates being prone to derailment, but also ensures the smoothness of steel plate conveying and improves the processing stability of subsequent processes such as layer cooling and coiling.

[0025] 4. The precise lubrication mechanism triggered by the position sensor in this solution controls the hydraulic cylinder to push the lubricating oil only when the steel plate passes through, realizing on-demand lubrication of the sliding track. Compared with the continuous lubrication mode, it reduces the waste of lubricating oil and effectively reduces the frictional resistance between the liner and the track, further extending the service life of key components of the equipment.

[0026] This invention simultaneously achieves precise lubrication of the sliding track and centering and guiding adjustment of the steel plate, greatly simplifying the equipment structure, reducing operating energy consumption, and meeting the actual needs of continuous and efficient operation of hot rolling production lines.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] Example 1:

[0036] Reference Figures 1-6 A transition guide platform at the exit of a finishing mill includes: a platform 1, with connecting blocks 4 fixedly installed on both sides of the platform 1; a water collection hopper 5 connected to the bottom of the two connecting blocks 4; supports 6 installed on both the left and right sides of the bottom of the water collection hopper 5; a connecting pipe 25 installed at the bottom of the water collection hopper 5; a valve installed inside the connecting pipe 25; and a water collection tank 7 fixedly installed at the bottom of the connecting pipe 25. The platform also includes:

[0037] Two sliding tracks 2 are both set on the outer surface of the platform 1. Multiple liner plates 3 are slidably connected on the sliding tracks 2. The multiple liner plates 3 are connected in series by the same hinge to form a closed ring chain. The platform 1 is rotatably equipped with a drive sprocket and a driven sprocket. The closed ring chain is wrapped around the outer circumference of the drive sprocket and the driven sprocket. Driven by the drive sprocket, the closed ring chain and the connected liner plates 3 can be rotated in a cycle. Both the left and right ends of the platform 1 are provided with connecting grooves 23. The connecting grooves 23 connect the sliding track 2 at the top of the platform 1 and the return channel at the bottom of the platform 1. The liner plates 3 are used to travel along the sliding track 2 from the top of the platform 1 through one side connecting groove 23 to the bottom of the platform 1, and then return to the top of the platform 1 through the other side connecting groove 23, so as to realize the cyclic rotation of the liner plates 3.

[0038] The lubrication mechanism is located inside the connecting block 4 on the right side. It is used to deliver lubricating medium to the sliding rail 2, reduce the frictional resistance between the liner 3 and the sliding rail 2, and ensure that the steel plate can smoothly drive the liner 3 to move by its own thrust.

[0039] The adjustment mechanism is located on the front and rear sides of platform 1 and is used to center and guide the steel plate passing through platform 1 to prevent the steel plate from deviating from the conveying track.

[0040] The power mechanism, located on the lubrication mechanism, is used to convert the linear motion power of the lubrication mechanism into the driving power of the adjustment mechanism, so as to realize the linkage and synchronization of the lubrication action and the centering adjustment action.

[0041] Reference Figure 2 and Figure 4 The lubrication mechanism includes a hydraulic cylinder 9 located on the left side inside the connecting block 4 on the right side. A sealing plate 8 is fixedly installed at the output end of the hydraulic cylinder 9, and the sealing plate 8 is slidably connected to the connecting block 4. The connecting block 4 stores lubricating oil inside, and an oil injection hole is opened at the top of the connecting block 4. A one-way valve is installed in the oil injection hole to prevent the lubricating oil from flowing back. Two fixed slots 24 are symmetrically opened at the top of the platform 1. A nozzle 10 is fixedly connected inside each of the two fixed slots 24. The output ends of the two nozzles 10 are respectively aligned with the two sliding rails 2. An opening 26 is opened on the left side inside the connecting block 4. A diversion pipe is fixedly connected to the output end of the opening 26. The diversion pipe includes a main pipe and two branch pipes. The input end of the main pipe is sealed and connected to the opening 26. The output ends of the two branch pipes are respectively sealed and fixedly connected to the two nozzles 10. A sensor 27 is installed at the top of the platform 1. The position sensor 27 is used to detect... The signal indicates the passage of the steel plate. When sensor 27 detects the passage of the steel plate, it triggers the hydraulic cylinder 9 to start. The output end of the hydraulic cylinder 9 pushes the sealing plate 8 to move to the right by a preset stroke. On the one hand, the lubricating oil in the connecting block 4 is delivered to the two nozzles 10 through the opening 26 and the diversion pipe to precisely lubricate the sliding track 2. On the other hand, the adjustment plate 12 is driven to move through the linkage of the power mechanism to achieve the centering guidance of the steel plate. Through the preset gear transmission ratio design, this stroke can drive the cam 15 to rotate one revolution, thereby achieving the guiding action of the adjustment plate 12 to quickly approach and then separate. Only when the lubricating oil in the connecting block 4 is exhausted does it need to be controlled to reset the hydraulic cylinder 9 to replenish the lubricating oil. On the one hand, the lubricating oil in the connecting block 4 is delivered to the two nozzles 10 through the opening 26 and the diversion pipe to precisely lubricate the sliding track 2. On the other hand, the adjustment plate 12 is driven to move through the linkage of the power mechanism to achieve the centering guidance of the steel plate.

[0042] Reference Figures 1-3 and Figure 5The adjustment mechanism includes two grooves 11 respectively opened on the front and rear sides of the platform 1. An adjustment plate 12 is rotatably connected in each of the two grooves 11. A rotating shaft 28 is fixedly installed on the left end of each of the two adjustment plates 12. The adjustment action of the two adjustment plates 12 is only a fine-tuning guide that moves closer to each other. The purpose is to bring the deviated steel plate back to the center conveying trajectory. It is not a rigid clamping, so it will not generate resistance to the conveying of the steel plate and ensure that the steel plate can run smoothly and continuously. Gears 29 are fixedly installed on the outer surface of each of the two rotating shafts 28. Both gears 29 are meshed with racks 13. The racks 13 are slidably connected to the platform 1. Two rotating columns 14 are symmetrically rotatably connected on the front and rear sides of the platform 1. Cams 15 are fixedly installed on the outer surface of each of the two rotating columns 14. Cam grooves are opened around the periphery of each of the two cam grooves. Reciprocating rods 16 are slidably connected in each of the two cam grooves. The ends of the two reciprocating rods 16 that are far apart from each other are fixedly connected to the two racks 13 respectively.

[0043] Reference Figure 3 , Figure 5 and Figure 6 The power mechanism includes two racks 18 fixedly connected to the left side wall of the sealing plate 8. Both racks 18 are meshed with gears 19. Both gears 19 are fixedly mounted with rotating columns 20. Both rotating columns 20 are rotatably connected to the connecting block 4. The bottom ends of both rotating columns 20 extend through the connecting block 4 into the interior of the platform 1. Both rotating columns 20 are fixedly mounted with sprockets 21 on their outer surfaces. Both rotating columns 14 are fixedly mounted with sprockets 17 on their outer surfaces. Both sprockets 17 and sprockets 21 are meshed with the same chain 22.

[0044] The implementation principle of the transition guide platform at the exit of a finishing mill in this application embodiment is as follows: When in use, after the high-temperature steel plate after finishing milling enters the platform 1, it relies on its own conveying thrust to act on the liner plate 3; the active sprocket inside the platform 1 drives the annular closed chain to connect each liner plate and move along the sliding track 2. The liner plate 3 drives the steel plate to be conveyed forward. At the same time, the liner plate 3 realizes the top conveying, bottom return and top reset cycle through the connecting grooves 23 at the left and right ends of the platform 1, so as to avoid the single liner plate being worn by the high-temperature steel plate for a long time.

[0045] When the position sensor 27 at the top of platform 1 detects the signal of the steel plate passing through, the hydraulic cylinder 9 of the lubrication mechanism is automatically triggered to start. The output end of the hydraulic cylinder 9 pushes the sealing plate 8 to move to the right by a preset stroke, squeezing the lubricating oil stored in the connecting block 4. The lubricating oil enters the diversion pipeline through the opening 26 and is precisely sprayed onto the corresponding sliding track 2 through two nozzles 10, reducing the frictional resistance between the liner 3 and the track, and ensuring the smooth circulation of the liner 3 and the conveying of the steel plate.

[0046] Through the preset transmission ratio design, the small stroke of the hydraulic cylinder 9 forward can drive the gear 19 meshing with the rack 18 on its left side to rotate. The gear 19 drives the sprocket 21 at the bottom to rotate synchronously once through the rotating column 20. The sprocket 21 drives the sprocket 17 and the rotating column 14 inside the platform 1 to rotate synchronously once through the chain 22. The cam 15 on the rotating column 14 drives the reciprocating rod 16 to make a linear motion close to the steel plate through the cam groove, pulling the rack 13 to slide. The rack 13 drives the meshing gear 29 and the rotating shaft 28 to rotate, so that the adjusting plates 12 in the groove 11 quickly move closer to each other, and center the offset steel plate. Then the cam continues to rotate, and drives the reciprocating rod 16 to reset in the opposite direction through the cam groove. The adjusting plates 12 separate synchronously, without affecting the subsequent steel plate conveying.

[0047] Cooling water or de-cooling water carried during the steel plate conveying process falls onto platform 1, and is collected in water collection hopper 5 via connecting blocks 4 on both sides of platform 1. Finally, it flows into water collection tank 7 through connecting pipe 25, which can be controlled by valves to prevent cooling water from overflowing and affecting equipment operation.

[0048] Example 2:

[0049] The difference between this embodiment and Embodiment 1 is that a filter screen is installed inside the water collection hopper 5. The filter screen 30 is horizontally installed inside the water collection hopper 5 near the top. The cooling water is first filtered through the filter screen 30 inside the water collection hopper 5 to remove impurities such as iron oxide scale and debris mixed in the water. Finally, it flows into the water collection tank 7 through the connecting pipe 25, which can be controlled by a valve to prevent impurities from clogging the connecting pipe 25 or contaminating the water collection tank. At the same time, it prevents the cooling water from overflowing and affecting the operation of the equipment.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
