Description

Technical Field

[0001] This invention relates to the field of dismantling technology, and in particular to a carbon roller dismantling device. Background Technology

[0002] During the production process of silicon steel production lines, the core of the carbon sleeve rollers used in continuous annealing of silicon steel is prone to damage due to various reasons. There are no convenient tools for disassembling and assembling the core, and a hammer is needed to knock the retaining ring to disengage it from the core. This disassembly method is not only inefficient, but also easy to damage the carbon sleeve by hitting the hammer, and the retaining ring is also easy to deform. Therefore, a disassembly device is needed to disassemble the carbon sleeve rollers.

[0003] A Chinese patent with publication number CN204075631 U discloses a device for disassembling and assembling a coal mill roller bearing, including a support plate, a double-threaded support rod, a jack, a pad, a combined pressure plate, and a worktable. The combined pressure plate is placed on the detachable pressure end face of the roller bearing, the pad is placed on the combined pressure plate, and the jack is placed on the pad. The combined pressure plate, pad, and jack are placed coaxially. The upper end of the double-threaded support rod is fitted with a through hole on the end face of the support plate, and the lower end of the double-threaded support rod is fitted with an existing threaded hole on the end face of the roller housing. The roller housing is placed horizontally. On the workbench, first place the roller core horizontally on the workbench, then disassemble the combined pressure plate into three sector plates and one connecting plate. Place the three sector plates on the detachable pressure end face of the roller core bearing in sequence, and then assemble them with the connecting plate. Place the pad on the combined pressure plate, place the jack on the pad, and assemble the lower end of the double-threaded support rod with the original threaded hole on the end face of the roller core housing. Assemble the upper end of the double-threaded support rod with the through hole made on the end face of the support plate. Under the reaction force, the jack presses the roller core bearing out of the through hole of the workbench.

[0004] In the current technology, the roller core bearing is pressed out of the through hole of the worktable by the reaction force of the jack. Under the action of high pressure, the roller core is easily damaged. Moreover, the pressure is large at the moment the roller core is pressed out of the through hole, and the roller core is easy to roll off or jump up, which poses a safety hazard to the operator.

[0005] Therefore, the present invention provides a carbon roller disassembly device. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the high pressure of the jack in the prior art can easily lead to damage to the roller core, and the roller core is prone to rolling off or jumping up, which poses a safety hazard to the operator.

[0012] The disassembly unit includes a bracket, with a threaded rod threadedly connected to the middle of the bracket; a first rotating block is fixedly connected to one end of the threaded rod, and rotating rods are rotatably connected to both ends of the bracket via pins; a pull rod is fixedly connected to one end of each rotating rod; bolt holes are provided on the outer side of each pull rod, and the pull rods are inserted into the bolt holes; a threaded hole is provided on the side wall of the first rotating block away from the threaded rod, and an electric wrench is connected inside and outside the threaded hole. The electric wrench is used to rotate the threaded rod to pull out the retaining ring for disassembly.

[0013] In one embodiment of the present invention, a fixed plate is rotatably connected to the outer side of the threaded rod via a bearing, and a bidirectional ball screw is rotatably connected to the other two side walls of the fixed plate via bearings. Both ends of the bidirectional ball screw are threaded with movable blocks, and the two movable blocks are symmetrical about the fixed plate. A second rotating block is fixedly connected to one end of the bidirectional ball screw.

[0014] In one embodiment of the present invention, the top of each of the movable blocks is rotatably connected to a collar via a rotating shaft, and the rotating rods are slidably connected inside the collar.

[0015] In one embodiment of the present invention, each of the fixed rings has a groove, and four gears are rotatably connected to each groove via a rotating shaft; the gears are arranged in a circle, and a rack is provided on one side of each gear. The gears mesh with the racks, the racks are slidably connected to the fixed rings, and an arc-shaped plate is fixedly attached to the bottom of each rack. The arc-shaped plate is in close contact with the outer wall of the carbon roller body.

[0016] In one embodiment of the present invention, the shafts of the two gears at the same position are all fixedly connected to a connecting rod; the connecting rod is used for the synchronous rotation of the gears at both ends, and a motor is fixedly connected to the outer wall of one of the fixed rings, the output shaft of the motor being fixedly connected to the shaft of one of the gears.

[0017] In one embodiment of the present invention, eight rotating wheels are provided on the side wall of the fixed ring near the motor, wherein four of the rotating wheels are fixed to the outside of the connecting rod, and a belt is sleeved on the outside of the rotating wheels; the other four rotating wheels are rotatably connected to the fixed ring by pins, and the rotating wheels are all located on the outside of the belt.

[0018] In one embodiment of the present invention, the other end of the threaded rod is tapered, and the tapered end of the threaded rod is inserted into one end of the carbon roller body to facilitate alignment and positioning.

[0019] In one embodiment of the present invention, the inner sidewalls of the arc-shaped plate are all fixed with anti-slip textures, and the anti-slip textures are made of one of polyurethane, acrylic or epoxy.

[0020] In one embodiment of the present invention, two support columns are fixedly connected to the bottom of each fixing ring, and the support columns are used to fix and support the fixing ring and the carbon roller body.

[0021] In one embodiment of the present invention, two guide rods are slidably connected to the two movable blocks, and the guide rods are fixed to the fixed plate.

[0022] The technical solution of the present invention has the following advantages compared with the prior art:

[0023] This invention discloses a carbon sleeve roller disassembly device. It employs a rotating rod and a threaded rod. By adjusting the angle of the rotating rod, the pull rod at one end is inserted into the bolt hole for locking. An electric wrench is aligned with the threaded opening, and the wrench drives the first rotating block to rotate through the threaded opening. The first rotating block drives the threaded rod to rotate, and the threaded rod moves the bracket closer to the carbon sleeve roller. The bracket then drives the rotating rod closer to the carbon sleeve roller. Adjusting the length of the connecting rod allows the tapered end of the threaded rod to be pressed against one end of the carbon sleeve roller body, thus fixing the carbon sleeve roller and the disassembly unit. The electric wrench continues to rotate, driving the threaded rod through the threaded opening. The threaded rod drives the bracket further away from the carbon sleeve roller body, and the bracket drives the rotating rod further away from the carbon sleeve roller. During this movement, the rotating rod drives the pull rod, which pulls the retaining ring through the threaded bolt hole for disassembly. Using a movable disassembly puller not only protects the carbon sleeve equipment and extends its service life but also effectively improves operational efficiency.

[0024] The carbon roller disassembly device of the present invention uses gears and belts. By driving the gears to rotate, the gears mesh with the rack, so the gears drive the rack to move, and the rack drives the arc plate to move. The arc plate moves and makes close contact with the carbon roller body, thereby fixing the carbon roller. The fixing rings are provided with grooves, which increases the movement space of the arc plate and makes it easier to fix carbon rollers of different sizes.

[0025] The carbon roller disassembly device of this invention comprises rotating wheels and belts. First, the motor is turned on, and the output shaft of the motor drives the rotating shaft to rotate. The rotating shaft drives the gears and rotating wheels to rotate. When the rotating wheels rotate, they drive the belt to rotate. Since the belt is sleeved on the outer side of four rotating wheels, the rotating wheels move synchronously, thereby achieving synchronous movement of the gears. The other four rotating wheels are rotatably connected to the fixed ring by pins, and all rotating wheels are located on the outer side of the belt. The belt is subjected to external force during rotation, reducing the possibility of slippage. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0037] Please see Figure 1 - Figure 8 The present invention provides a carbon roller disassembly device, comprising:

[0038] Carbon roller body 1;

[0039] 2. A retaining ring fitted onto the outer wall of the carbon roller;

[0040] A fixing ring 4 is provided on the outside of the carbon roller body 1, and a fixing device is provided on the fixing ring 4;

[0041] A disassembly unit is provided on one side of the retaining ring 2, the disassembly unit being used to disassemble the pull-code retaining ring 2;

[0042] The disassembly unit includes a bracket 3, with a threaded rod 32 threadedly connected to the middle of the bracket 3; a first rotating block 34 is fixedly connected to one end of the threaded rod 32, and both ends of the bracket 3 are rotatably connected to rotating rods 31 via pins; a pull rod 310 is fixedly connected to one end of each rotating rod 31; bolt holes are provided on the outer side of each pull rod 310, and each pull rod 310 is inserted into the bolt holes; a threaded hole is provided on the side wall of the first rotating block 34 away from the threaded rod 32, and an electric wrench is connected inside and outside the threaded hole. The electric wrench is used to rotate the threaded rod 32 to pull out the retaining ring 2 for disassembly.

[0043] When using the disassembly unit provided by this invention, firstly, the carbon roller body 1 is fitted into the fixing ring 4. The fixing ring 4 is then moved to one side of the threaded rod 32. Then, by adjusting the angle of the rotating rod 31, the pull rods 310 at one end of the rotating rod 31 are inserted into the bolt holes for locking. An electric wrench is then aligned with the threaded opening. The electric wrench drives the first rotating block 34 to rotate through the threaded opening. The first rotating block 34 drives the threaded rod 32 to rotate. The threaded rod 32 drives the bracket 3 to move closer to the carbon roller. The bracket 3 then drives the rotating rod 31 to move closer to the carbon roller. Adjusting the length of the connecting rod 47 allows the disassembly unit to be disassembled. One conical end of the threaded rod 32 abuts against one end of the carbon sleeve roller body 1, completing the fixing and disassembly unit of the carbon sleeve roller. The electric wrench continues to rotate, and the electric wrench drives the threaded rod 32 to rotate through the threaded end. The threaded rod 32 drives the bracket 3 to move away from the carbon sleeve roller body 1. The bracket 3 drives the rotating rod 31 to move away from the carbon sleeve roller. During the movement, the rotating rod 31 drives the pull rod 310 to move. The pull rod 310 pulls the retaining ring 2 through the threaded bolt hole for disassembly. After using the movable disassembly puller, not only is the service life of the carbon sleeve equipment extended, but the operating efficiency is also effectively improved.

[0044] Furthermore, such as Figure 2 and Figure 3As shown, a fixed plate 33 is rotatably connected to the outer side of the threaded rod 32 via a bearing. Two other sidewalls of the fixed plate 33 are rotatably connected to a bidirectional ball screw 36 via bearings. Both ends of the bidirectional ball screw 36 are threadedly connected to a moving block 35. The two moving blocks 35 are symmetrical about the fixed plate 33. A second rotating block 39 is fixedly connected to one end of the bidirectional ball screw 36.

[0045] When in use, the bidirectional ball screw 36 provided by the present invention rotates according to the size of the carbon roller body 1 by rotating the second rotating block 39. The second rotating block 39 drives the bidirectional ball screw 36 to rotate, and the bidirectional ball screw 36 drives the moving block 35 to rotate. A ball nut seat is provided at the connection between the bidirectional ball screw 36 and the moving block 35. The ball nut seat ensures the radial movement of the moving block 35. During the movement, the moving block 35 drives the rotating rod 31 to rotate in different directions, thereby realizing the function of disassembling carbon rollers of different sizes.

[0046] Furthermore, such as Figure 3 As shown, the top of each of the moving blocks 35 is rotatably connected to a collar 38 via a rotating shaft, and the rotating rods 31 are slidably connected inside the collar 38.

[0047] When in use, the collar 38 provided by the present invention is rotatably connected to the top of the moving block 35 via a rotating shaft, so that the collar 38 can rotate with the rotation of the rotating rod 31. The rotating rod 31 is slidably connected inside the collar 38, so that the collar 38 will not affect the normal rotation and sliding of the rotating rod 31, thus achieving better disassembly operations.

[0048] Furthermore, such as Figure 4 As shown, each of the fixed rings 4 has a groove 42, and each groove 42 is rotatably connected to four gears 43 via a rotating shaft; the gears 43 are arranged in a circle, and each gear 43 has a rack 41 on one side, and the gears 43 mesh with the racks 41. The racks 41 are slidably connected to the fixed ring 4, and each rack 41 has an arc plate 44 fixed to its bottom, and the arc plate 44 is in close contact with the outer wall of the carbon roller body 1.

[0049] When the gear 43 and rack 41 provided by the present invention are used to fix the carbon sleeve roller, the gear 43 is driven to rotate, and the gear 43 meshes with the rack 41. Therefore, the gear 43 drives the rack 41 to move, and the rack 41 drives the arc plate 44 to move. The arc plate 44 moves and comes into close contact with the carbon sleeve roller body 1, thereby fixing the carbon sleeve roller. The fixing ring 4 is provided with grooves 42, which increases the movement space of the arc plate 44 and makes it easier to fix carbon sleeve rollers of different sizes.

[0050] Furthermore, such as Figure 5 and Figure 8As shown, the shafts of the two gears 43 at the same position are both fixedly connected to a connecting rod 47; the connecting rod 47 is used for the synchronous rotation of the gears 43 at both ends, and a motor 46 is fixedly connected to the outer wall of one of the fixed rings 4, and the output shaft of the motor 46 is fixedly connected to the shaft of one of the gears 43.

[0051] When in use, the connecting rod 47 provided by the present invention is provided with two fixing rings 4 to facilitate the fixing of the carbon roller body 1. Under the action of the connecting rod 47, the two fixing rings 4 form a closed loop, which increases the stability. The gears 43 are provided at both ends of the connecting rod 47 to realize the synchronous movement of the gears 43 on both sides of the connecting rod 47. By turning on the motor 46, the motor 46 drives the rotating shaft to rotate through the output shaft. The rotation of the rotating shaft drives the gear 43 to rotate. The gear 43 drives the rotation of the other gear 43 through the connecting rod 47.

[0052] Furthermore, such as Figure 7 As shown, eight rotating wheels 48 are provided on the side wall of the fixed ring 4 near the motor 46. Four of the rotating wheels 48 are fixed to the outside of the connecting rod 47, and a belt 49 is sleeved on the outside of the rotating wheels 48. The other four rotating wheels 48 are rotatably connected to the fixed ring 4 by pins, and all of the rotating wheels 48 are located on the outside of the belt 49.

[0053] When the rotating wheel 48 and belt 49 provided by the present invention are in use, the motor 46 is turned on, and the output shaft of the motor 46 drives the rotating shaft to rotate. The rotating shaft drives the gear 43 and the rotating wheel 48 to rotate. When the rotating wheel 48 rotates, it drives the belt 49 to rotate. Since the belt 49 is sleeved on the outer side of the four rotating wheels 48, the synchronous movement of the rotating wheels 48 is achieved, thereby achieving the synchronous movement of the gear 43. The other four rotating wheels 48 are rotatably connected to the fixed ring 4 by pins, and the rotating wheels 48 are all located on the outer side of the belt 49. The belt 49 is subjected to external force during rotation, reducing the possibility of slippage.

[0054] Furthermore, such as Figure 3 As shown, the other end of the threaded rod 32 is tapered, and the tapered end of the threaded rod 32 is inserted into one end of the carbon roller body 1 for easy alignment and positioning.

[0055] When the threaded rod 32 provided by the present invention is used, one end of the threaded rod 32 is made into a tapered shape, which makes it easy to insert into one end of the carbon roller body 1 and achieve alignment and positioning.

[0056] Furthermore, such as Figure 5 As shown, the inner sidewalls of the arc-shaped plate 44 are all fixed with anti-slip patterns, which are made of polyurethane, acrylic or epoxy.

[0057] When the anti-slip texture provided by the present invention is used, the inner side wall of the arc plate 44 is provided with anti-slip texture to prevent the carbon sleeve roller body 1 from rotating and affecting disassembly. The material is selected from polyurethane, acrylic or epoxy to prevent excessive force from damaging the outer side of the carbon sleeve roller body 1.

[0058] Furthermore, such as Figure 6 As shown, each of the fixed rings 4 has two support columns 45 fixedly connected to its bottom. The support columns 45 are used to fix and support the fixed rings 4 and the carbon roller body 1.

[0059] When in use, the support column 45 provided by the present invention is used to fix and support the fixing ring 4 and the carbon roller body 1, and the support column 45 has a certain height to facilitate disassembly.

[0060] Furthermore, such as Figure 2 As shown, two guide rods 37 are slidably connected to the two moving blocks 35, and the guide rods 37 are fixed to the fixed plate 33.

[0061] When the guide rod 37 provided by the present invention is in use, the moving block 35 slides on the guide rod 37 during the movement process, and the guide rod 37 limits the moving block 35 in the horizontal direction.

[0062] Working principle: First, the motor 46 is turned on. The output shaft of the motor 46 drives the rotating shaft to rotate, which in turn drives the gear 43 and the rotating wheel 48 to rotate. When the rotating wheel 48 rotates, it drives the belt 49 to rotate. Since the belt 49 is fitted on the outer side of four rotating wheels 48, the rotating wheels 48 move synchronously, thereby achieving the synchronous movement of the gear 43. The other four rotating wheels 48 are rotatably connected to the fixed ring 4 by pins, and all rotating wheels 48 are located on the outer side of the belt 49. The belt 49 is subjected to external force during rotation, reducing the possibility of slippage. The gear 43 meshes with the rack 41, so the gear 43 drives the rack 41 to move, and the rack 41 drives the arc plate 4. 4. Movement: The arc-shaped plate 44 moves and makes close contact with the carbon roller body 1 to fix the carbon roller. Grooves 42 are provided inside each fixing ring 4, increasing the movement space of the arc-shaped plate 44 and facilitating the fixing of carbon rollers of different sizes. The fixing ring 4 is moved to one side of the threaded rod 32, and then the second rotating block 39 is rotated. The second rotating block 39 drives the bidirectional ball screw 36 to rotate, which in turn drives the moving block 35 to rotate. A ball nut seat is provided at the connection between the bidirectional ball screw 36 and the moving block 35, ensuring the radial movement of the moving block 35. During movement, the moving block 35 drives the rotating rod 31 to rotate in a non-linear direction. Rotating in the same direction, the pull rods 310 at one end of the rotating rod 31 are all inserted into the bolt holes for locking. The collar 38 is rotatably connected to the top of the moving block 35 via a rotating shaft, allowing the collar 38 to rotate with the rotating rod 31. The rotating rod 31 is slidably connected inside the collar 38, ensuring that the collar 38 does not affect the normal rotation and sliding of the rotating rod 31. By aligning an electric wrench with the threaded end, the electric wrench drives the first rotating block 34 to rotate through the threaded end. The first rotating block 34 drives the threaded rod 32 to rotate, and the threaded rod 32 drives the bracket 3 to move closer to the carbon roller. The bracket 3 then drives the rotating rod 31 to move closer to the carbon roller. Adjusting the length of the connecting rod 47 allows the tapered end of the threaded rod 32 to be pressed against one end of the carbon sleeve roller body 1, thus fixing the carbon sleeve roller and the disassembly unit. The electric wrench continues to rotate, driving the threaded rod 32 to rotate through the threaded end. The threaded rod 32 drives the bracket 3 to move away from the carbon sleeve roller body 1. The bracket 3 drives the rotating rod 31 to move away from the carbon sleeve roller. During the movement, the rotating rod 31 drives the pull rod 310 to move. The pull rod 310 pulls the retaining ring 2 through the threaded bolt hole for disassembly. Using the movable disassembly puller not only protects the carbon sleeve equipment and extends its service life, but also effectively improves the operating efficiency.

[0063] Obviously, the above embodiments are merely illustrative examples for clarity and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
