Technical Field

[0001] The invention belongs to the technical field of casing processing, in particular to a casing sleeve method and device. Background Art

[0002] During the casing processing, the casing needs to be sleeved. The traditional sleeve method usually adopts a single pulling point design, and the casing is stretched and fixed manually or by a simple mechanical structure. Although this method can meet the basic processing needs to a certain extent, there are many problems and limitations in practical applications. It is often difficult to achieve uniform pulling and stable clamping, resulting in unstable product quality and low production efficiency.

[0003] The traditional method usually has only one sleeve pulling point, and it is impossible to achieve uniform sleeve pulling at multiple points. This causes uneven force on the casing during the sleeve pulling process, which is prone to over-stretching in certain parts, resulting in cracks and breaks in the casing, affecting the final quality of the product.

[0015] A casing sleeve method comprises the following steps:

[0016] S1: elastically sleeve the casing piece onto the pulling ring, ensure that the pulling ring can slide freely along the central axis of the casing piece, and use a locking outer ring to fix the casing piece onto the pulling ring;

[0017] S2: Turn on the power supply and start the driving motor. The output shaft of the driving motor drives the pulling shaft to rotate. The pulling shaft is installed between the two ear plates through the bearing to rotate smoothly.

[0018] S3: When the pulling shaft rotates, two symmetrical pulling ropes begin to be wound, and the pulling ropes pass through the rope threading holes, gradually transmitting the pulling force to the pulling ring. As the pulling ropes are wound, the pulling ring slides on the casing piece, driving the casing piece to be evenly stretched;

[0019] S4: When the casing piece is pulled, its inner wall is in frictional contact with the ball. The ball is located in the rolling gap chamber and can roll freely during the pulling process of the casing piece. The rolling of the ball reduces the friction between the casing piece and the end wall of the casing piece.

[0021] S6: The water in the water cavity is sprayed to the humidifying cotton ring in the form of fine water mist through the micron-sized water spray holes. The humidifying cotton ring absorbs the water and transfers the water to the casing through friction, further enhancing the moistening effect;

[0022] S7: When the casing piece reaches the required length, the driving motor is turned off and the rotation of the pulling shaft is stopped. At this time, the pulling rope is no longer entangled, the pulling sleeve ring stops sliding, and the casing piece remains in the state after being pulled by the sleeve.

[0023] Compared with the prior art, the technical effects and advantages of the present invention are as follows:

[0024] The casing sleeve device of this technical solution is arranged by multiple U-shaped extension frames arranged crosswise up and down, and the casing sleeve assembly is installed inside each U-shaped extension frame, and two pulling ropes are symmetrically connected outside the pulling ring, so that when pulling, the two pulling ropes pull at the same time, realizing multi-point uniform pulling. This design makes the casing pieces more evenly stressed during the pulling process, avoids the risk of local over-stretching or breakage, and ensures the stability of pulling. The pulling shaft drives the pulling rope to wind through the driving motor, realizing an automated pulling process. The operator does not need to manually adjust the tension, which reduces the influence of human factors and improves the pulling efficiency.

[0025] Due to the combination of multi-point uniform pulling and fastener clamping, this technical solution can ensure that the casing is evenly stressed during the pulling process, maintains a good shape, avoids local over-stretching or irregular deformation, and ultimately improves the overall quality of the product. By reducing friction, preventing scratches, and maintaining moisture, this technical solution effectively reduces damage and cracks to the casing during processing, reduces the defective rate, and improves the finished product rate.

[0039] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0040] Unless otherwise defined, the up, down, left, right, front, back, inside and outside directions involved in this document are based on the up, down, left, right, front, back, inside and outside directions in the figures shown in the present invention, and are explained here together.

[0041] This embodiment provides Figures 1 to 10A casing sleeve device is shown, comprising a base support 1 and a T-shaped support column 2 welded to the top surface of the base support 1, a plurality of U-shaped extension frames 4 are cross-mounted on both sides of the T-shaped support column 2, each U-shaped extension frame 4 has a casing sleeve assembly 5 inside, each casing sleeve assembly 5 includes a sleeve member 7 fixed to the inner wall of the U-shaped extension frame 4, a pulling ring 15 sleeved on the sleeve member 7 and capable of moving along the extension direction of the central axis of the sleeve member 7, two pulling ropes 16 symmetrically connected to the pulling ring 15 and a pulling shaft 20 rotatably installed on the outside of the U-shaped extension frame 4, and the length of the sleeve member 7 can be selected and installed according to actual needs.

[0042] In this embodiment, the outside of the pulling ring 15 is elastically sleeved with a casing piece 6, two pulling ropes 16 extend to the outside of the U-shaped extension frame 4 and are wound and pulled by the pulling shaft 20, and the outside of the pulling ring 15 also has a fastener that can clamp and wrap the casing piece 6 sleeved on the circumference of the pulling ring 15. The fastener fastens the casing piece 6 to the pulling ring 15, so that the pulling shaft 20 rotates to pull the pulling rope 16, and the pulling rope 16 pulls the pulling ring 15 to slide on the sleeve piece 7, so that the casing piece 6 is sleeved on the sleeve piece 7. The casing sleeve assembly 5 provides a smooth lining surface through the sleeve piece 7 to reduce friction and facilitate the smooth movement of the casing piece 6. The pulling ring 15 is elastically sleeved with the casing piece 6 to ensure that it will not slip during the pulling process. The casing piece 6 is firmly clamped through the cooperation of the locking outer ring 17 and the pressing block 26, thereby ensuring the stability and consistency of the casing piece 6 during the processing and avoiding quality problems caused by looseness or slippage. The use of the silicone anti-slip ring 28 further enhances the clamping effect and ensures that the casing piece 6 will not be damaged during the pulling process.

[0043] In this embodiment, the pulling ring 15 is elastically sleeved with the casing piece 6 to ensure that it will not slip off during the pulling process. The casing piece 6 is elastically sleeved on the outside and can be fixed by the locking outer ring 17 and the pressing block 26. A silicone anti-skid ring 28 is provided inside to enhance the clamping effect and prevent the casing piece 6 from sliding, ensuring the stability and consistency of the casing piece 6 during the pulling process, avoiding quality problems caused by looseness or slipping. The use of the silicone anti-skid ring 28 further enhances the clamping effect and ensures that the casing piece 6 will not be damaged during the pulling process. The pulling rope 16 is wound around the pulling shaft 20 to pull and fix the casing piece 6. One end is fixed on the pulling ring 15, and the other end passes through the rope threading hole 31 and is connected to the pulling shaft 20. The casing piece 6 is evenly pulled by rotating the pulling shaft 20.

[0044] In this embodiment, the casing piece 6 is the casing to be processed, which is elastically sleeved on the pulling ring 15 and can slide on the sleeve piece 7 to facilitate processing operations. During the pulling process, the casing piece 6 slides along the sleeve piece 7 to achieve uniform stretching and fixation. By contacting with the humidifying cotton ring 30 and the micron-level water spray hole 34, it maintains appropriate moisture to prevent drying and cracking, ensures the flexibility and strength of the casing piece 6 during processing, avoids damage caused by excessive drying or improper pulling, and improves the processing quality and yield rate of the casing piece 6 through uniform stretching and fixation. The sleeve member 7 serves as the inner lining of the casing member 6, providing a smooth surface, reducing friction, and facilitating the smooth movement of the casing member 6. A water cavity 41 and a micron-level water spray hole 34 are provided inside, which can spray water into the casing member 6 to maintain appropriate humidity. A rolling ball 29 is embedded in one end of the sleeve member 7, and a rolling gap chamber 42 is formed by the clamping claw portion 36 and the blocking block 35 to prevent the ball 29 from falling off. The rolling of the ball 29 reduces the friction between the casing member 6 and the sleeve member 7, avoiding scratches and jams.

[0045] In this embodiment, the moving wheels 13 and the supporting feet 14 are installed at the bottom of the base bracket 1 to provide additional support points and enhance the stability of the device. The supporting feet 14 cooperate with the moving wheels 13 to ensure that the device remains stable in a stationary state. It can be adjusted according to the ground conditions to ensure that the device is placed horizontally to prevent the device from shaking or tilting during use, thereby ensuring the safety and stability of the operation.

[0046] In this embodiment, the fastener includes a locking outer ring 17 sleeved on the sleeve 7 , and the inner ring diameter of the locking outer ring 17 is larger than the outer ring diameter of the pulling ring 15 .

[0047] In this embodiment, a driving member is provided on the inner wall of the locking outer ring 17 , and a pressing block 26 is connected to one end of the driving member away from the inner wall of the locking outer ring 17 . The pressing block 26 is clamped on the outer wall of the casing 6 by the driving member.

[0048] In this embodiment, a silicone anti-slip ring 28 is bonded to the outer wall of the circumferential side of the pulling ring 15, and one end of the casing piece 6 clamped by the lower pressing block 26 is the casing pulling and pressing end 27. The lower pressing block 26 is an arc-shaped structure and matches the outer wall of the casing pulling and pressing end 27. The silicone anti-slip ring 28 is bonded to the outer wall of the circumferential side of the pulling ring 15, which increases the friction between the casing piece 6 and the pulling ring 15 and prevents the casing piece 6 from sliding during the pulling process. Its main function is to improve the reliability of clamping and ensure that the casing piece 6 will not fall off accidentally during the pulling process. The silicone material has good anti-slip properties and can provide additional friction between the pulling ring 15 and the casing piece 6. The silicone material is soft and elastic, which can protect the casing piece 6 during the clamping process and avoid damage to it, ensuring that the casing piece 6 will not slide or fall off during the pulling process, thereby improving the reliability of the operation. The soft silicone material reduces the risk of damage to the casing piece 6 and protects the product quality.

[0049] In this embodiment, the driving member includes a second locking bolt 25 threadedly connected to the outer wall of the locking outer ring 17. In some embodiments, the driving member also includes a compression spring 39 symmetrically fixed to the inner wall of the locking outer ring 17. The screw end of the locking outer ring 17 is connected to the back of the lower pressure block 26 through a bearing, so that the bearing is embedded in the back of the lower pressure block 26. When the second locking bolt 25 is screwed, the second locking bolt 25 is screwed in or out of the locking outer ring 17, thereby driving the lower pressure block 26 forward and backward, clamping and loosening the casing pulling and pressing end 27, and the compression spring 39 is welded to the back of the lower pressure block 26 at one end away from the locking outer ring 17. A positioning rod 40 is welded between the two compression springs 39 and on the back of the lower pressure block 26. The positioning rod 40 is welded between the two compression springs 39 and on the back of the lower pressure block 26. One end of the rod 40 away from the lower pressure block 26 extends to the outside of the locking outer ring 17. When it is necessary to clamp the casing to pull and press the end 27, the positioning rod 40 is pulled to make the lower pressure block 26 first close to the inner wall of the locking outer ring 17, so that the locking outer ring 17 is sleeved on the outside of the pulling ring 15. The positioning rod 40 is loosened, and under the elastic force of the compression spring 39, the lower pressure block 26 is elastically driven to clamp the outer wall of the casing pulling and pressing end 27, thereby improving the clamping work efficiency. The casing pulling and pressing end 27 can be clamped without manual twisting and force. The compression spring 39 is symmetrically fixed to the inner wall of the locking outer ring 17, and one end is welded to the back of the lower pressing block 26. The compression spring 39 provides a continuous elastic thrust for the lower pressing block 26, ensuring that the lower pressing block 26 can fit tightly against the casing pulling and pressing end 27, thereby achieving a stable clamping effect. When it is necessary to clamp the casing piece 6, the positioning rod 40 is pulled so that the lower pressing block 26 first fits close to the inner wall of the locking outer ring 17, and then the positioning rod 40 is released. Under the elastic force of the compression spring 39, the lower pressing block 26 will automatically pop out and clamp the casing pulling and pressing end 27. This design reduces the operation of manually tightening the bolts and improves work efficiency. The compression spring 39 can also play a certain buffering role, preventing the lower pressing block 26 from applying excessive pressure to the casing piece 6 and avoiding damage to the casing piece 6. Through the automatic clamping function of the compression spring 39, the operator does not need to manually tighten the bolts, which simplifies the operation steps and improves work efficiency. The positioning rod 40 is used to control the in and out movement of the lower pressing block 26. By pulling or releasing the positioning rod 40, the position of the lower pressing block 26 can be easily adjusted, thereby achieving the clamping and loosening of the casing pulling and pressing end 27. The operator can control the movement of the lower pressing block 26 through a simple pulling or releasing action, without the need for complicated tools or equipment, and the operation is very simple. The design of the positioning rod 40 ensures that the movement of the lower pressing block 26 is consistent each time it is clamped, avoiding the problem of uneven clamping due to human factors. The design of the positioning rod 40 greatly simplifies the clamping and loosening operation process, saves time and labor, and improves overall production efficiency. Since the positioning rod 40 provides a clear operation method, the operator can control the position of the lower pressing block 26 more accurately, reducing errors caused by improper operation.

[0050] In this embodiment, a ball 29 is rolled and embedded in one end of each sleeve member 7 away from the inner wall of the U-shaped extension frame 4, and a clamping claw portion 36 is provided around the ball 29 and located at the end of the sleeve member 7, and the clamping claw portion 36 surrounds the ball 29. The ball 29 is embedded in one end of the sleeve member 7 away from the inner wall of the U-shaped extension frame 4, and is surrounded by the clamping claw portion 36. The main function of the ball 29 is to frictionally contact the inner wall of the casing 6 when it is pulled, reduce friction by rolling, prevent the end wall of the sleeve 7 from scratching the casing 6, and make the casing 6 easier to slide. The rolling design of the ball 29 significantly reduces the friction between the casing 6 and the sleeve 7, making the casing 6 smoother during the pulling process. The existence of the ball 29 prevents the end wall of the sleeve 7 from directly contacting the casing 6, preventing scratches or damage. The rolling of the ball 29 can also help to bring out the water in the water cavity 41, further lubricate the inner wall of the casing 6, reduce friction, make the casing 6 smoother during the pulling process, reduce the difficulty of operation, avoid direct contact between the end wall of the sleeve 7 and the casing 6, and reduce the risk of scratches and damage. The rolling of the ball 29 in the rolling gap chamber 42 not only reduces friction, but also promotes the flow of water. When the ball 29 rolls, it drives the water in the water cavity 41 to flow out from the gap between the ball 29 and the rolling gap chamber 42, further wetting the inner wall of the casing 6, significantly improving the wetting effect, enhancing the lubrication effect, and reducing the jamming phenomenon.

[0051] In this embodiment, a water cavity 41 is provided inside the sleeve member 7, and a blocking block 35 is provided behind the ball 29 and the clamping claw portion 36 and inside the sleeve member 7. The blocking block 35 blocks the ball 29 from entering the water cavity 41. The inner wall of the clamping claw portion 36 has a pointed cone-shaped retracted portion 37, and the blocking block 35 has an extended resisting portion 38 on the side facing the ball 29. The pointed cone-shaped retracted portion 37 and the extended resisting portion 38 enclose a rolling gap chamber 42 that accommodates and prevents the ball 29 from falling off. When the casing piece 6 is sleeved on the sleeve piece 7 and the sleeve is pulled, the inner wall of the casing piece 6 is in frictional contact with the ball 29, and the ball 29 is driven to roll in the rolling gap chamber 42 by this friction force, thereby preventing the end wall of the sleeve piece 7 from scratching the casing piece 6 and preventing the sleeve from getting stuck. In addition, the rolling of the ball 29 can drive the water in the water cavity 41 to flow out from the gap between the rolling gap chamber 42 and the ball 29, thereby contacting the inner wall of the casing piece 6, so that the casing piece 6 is slightly moistened, so that the sleeve is easier to operate and not easy to break. By controlling the temperature of the water flow, the water cavity 41 can also help adjust the temperature of the casing piece 6 to avoid affecting the quality and processing effect of the casing due to too high or too low temperature. The uniform moist environment provided by the water cavity 41 helps to maintain the elasticity and flexibility of the casing piece 6, reduce the occurrence of quality problems such as cracks and breaks, and ultimately improve the overall quality of the product.

[0052] In this embodiment, the clamping jaw portion 36 is located at the end of the sleeve member 7, surrounding the ball 29 to form a closed space, ensuring that the ball 29 can only roll in the rolling gap chamber 42, and will not fall out of or enter the water chamber 41. The design of the clamping jaw portion 36 allows the ball 29 to roll freely when the casing piece 6 is pulled, reducing friction and preventing the casing piece 6 from being scratched. The pointed cone retracted portion 37 is located on the inner wall of the clamping jaw portion 36, and together with the extended resisting portion 38, encloses the rolling gap chamber 42. The design of the pointed cone retracted portion 37 allows the ball 29 to move only within a certain range when rolling, preventing it from rolling excessively or deviating from the track. The pointed cone retracted portion 37 is in the shape of a pointed cone, gradually shrinking outward, and plays a role in guiding the rolling direction of the ball 29. This design ensures that the ball 29 always remains on the correct track during the rolling process, avoiding damage to the casing piece 6 caused by irregular rolling.

[0053] In this embodiment, an annular groove 33 is provided on the circumference of the sleeve 7, and a plurality of micron-level water spray holes 34 are symmetrically provided on the inner wall of the annular groove 33, and the micron-level water spray holes 34 penetrate into the water cavity 41; in some embodiments, a humidifying cotton ring 30 is sleeved in the annular groove 33, and the outer wall of the humidifying cotton ring 30 is flush with the outer wall of the sleeve 7, so that the humidifying cotton ring 30 is in frictional contact with the inner wall of the casing 6, and a water pipe 23 is provided on one side of the tail end of the U-shaped extension frame 4, and the water pipe 23 is connected to a branch pipe 24, and the branch pipe 24 is connected to the water inlet hole 32 of the sleeve 7, so that the branch pipe 24 is connected to the water cavity 41, and the water pipe 23 is connected to the external water pump and water source to inject water into the water cavity 41. The branch pipe 24 connects the water pipe 23 to the water inlet hole 32 of the sleeve 7, and further communicates with the water cavity 41 inside the sleeve 7. Its main function is to ensure that water can be stably transmitted to each sleeve piece 7 and evenly sprayed through the micron-level water spray holes 34 to keep the casing pieces 6 moist. As a channel connecting the external water source and the internal water cavity 41 of the casing sleeve assembly 5, the branch pipe 24 ensures that water can be stably transmitted from the external water pump through the water pipe 23 to each sleeve piece 7. Through the branch design, the branch pipe 24 can evenly distribute water to multiple sleeve pieces 7 to ensure that each sleeve piece 7 can obtain sufficient moisture to meet the needs of casing pieces 6 in different positions. The continuous water supply reduces operation interruptions caused by drying or jamming, improves production efficiency, and keeps the casing pieces 6 moist, which helps reduce problems such as cracks and breakages, improves the overall quality of the product, reduces friction, indirectly protects the surface of the sleeve piece 7, and extends the service life of the equipment.

[0054] In this embodiment, the rolling gap chamber 42 provides a closed space for the ball 29, ensuring that the ball 29 can only roll therein without falling into the water cavity 41 or escaping from the sleeve member 7. The design of the rolling gap chamber 42 allows the ball 29 to roll freely therein, reducing the direct friction between the casing member 6 and the end wall of the sleeve member 7, preventing the sleeve member 7 from scratching the casing member 6. When the casing member 6 is pulled, the ball 29 rolls in the rolling gap chamber 42, driving the water in the water cavity 41 to flow out from the micron-sized water spray hole 34, further wetting the inner wall of the casing member 6. The design of the rolling gap chamber 42 ensures that the ball 29 can .... The smooth rolling of the ball 29 avoids the jamming of the casing piece 6 due to excessive friction, making the pulling process smoother. The design of the rolling gap chamber 42 significantly reduces the friction between the casing piece 6 and the sleeve piece 7, making the pulling process smoother and reducing the difficulty of operation and the risk of damage. By reducing friction and preventing scratches, the rolling gap chamber 42 effectively extends the service life of the casing piece 6, reduces the replacement frequency, and reduces production costs. The design of the rolling gap chamber 42 not only improves the smoothness of operation, but also ensures that the casing piece 6 will not be damaged during the pulling process, thereby ultimately improving the overall quality of the product.

[0055] In this embodiment, the humidifying cotton ring 30 is in frictional contact with the inner wall of the casing 6. The main function of the humidifying cotton ring 30 is to absorb water and transfer the water to the casing 6 through friction, keep it moist, and prevent it from drying and cracking. Since the humidifying cotton ring 30 is in close contact with the inner wall of the casing 6, it can ensure that the water is evenly distributed on the inner wall of the casing 6, keep the inner wall of the casing 6 moist, and prevent cracking or jamming caused by drying. The moistened casing 6 is easier to operate, reducing the resistance during the pulling process. The micron-level water spray holes 34 are symmetrically opened on the inner wall of the annular groove 33 and penetrate into the water cavity 41. The main function of the micron-sized water spray hole 34 is to spray the water in the water cavity 41 in the form of fine water mist to evenly moisten the inner wall of the casing piece 6 to prevent drying and cracking. The design of the micron-sized water spray hole 34 allows the water to be evenly sprayed in the form of fine water mist to ensure that the inner wall of the casing piece 6 is fully moistened. The aperture of the micron-sized water spray hole 34 is very small, which can effectively prevent excessive water spraying and avoid excessive moisture of the casing piece 6, ensuring that the inner wall of the casing piece 6 is always in an appropriate moist state, neither too dry nor too moist. The uniform water distribution reduces the operation interruption caused by drying or jamming, and improves production efficiency.

[0056] In this embodiment, the tail end of the U-shaped extension frame 4 has a sleeve pulling mechanism 8 for driving the pulling shaft 20 to rotate. The sleeve pulling mechanism 8 includes two ear plate members 19 symmetrically welded to the outer wall of the tail end of the U-shaped extension frame 4 and a driving motor 21 fixed to the outer wall of one of the ear plate members 19. The pulling shaft 20 is rotatably installed between the two ear plate members 19 through a bearing. The output shaft of the driving motor 21 is connected to the pulling shaft 20, thereby driving the pulling shaft 20 to rotate and pull the pulling rope 16 to wind. A rope threading hole 31 is provided on the outer wall of the U-shaped extension frame 4 near the pulling shaft 20 for the pulling rope 16 to pass through. An L top cover 18 is welded to the tail end of the top wall of the U-shaped extension frame 4. A hydraulic damper 22 is fixed to the inner wall of the L top cover 18. The damping end of the hydraulic damper 22 abuts against the driving motor 21, so that the hydraulic damper 22 can reduce shock and buffer the driving motor 21, thereby improving stability.

[0057] In this embodiment, multiple support rods 3 are symmetrically welded to the outer walls of both sides of the T-shaped support column 2, and multiple U-shaped extension frames 4 are cross-arranged and plugged into two adjacent support rods 3. The lower parts of both sides of the T-shaped support column 2 are connected to support edge columns 9 through first locking bolts 12, and multiple support caps 10 are symmetrically welded to the inner walls of the two support edge columns 9. Each support cap 10 is plugged and supported with the free end of the adjacent support rod 3. Threaded holes 11 are provided on both sides of the top surface of the T-shaped support column 2 and the top surface of the support edge column 9. The first locking bolts 12 pass through the threaded holes 11 and are fixedly connected to the support edge columns 9, so that the support edge columns 9 are erected on both sides of the lower side of the T-shaped support column 2 and plugged into the support rods 3, thereby completing the closure of both sides of the T-shaped support column 2, and can also support and erect the support rods 3, improve the supporting stability of the support rods 3, and prevent the support rods 3 from breaking. The supporting edge column 9 cooperates with the T-shaped supporting column 2 and the supporting frame rod 3 to form a closed frame structure to enhance the supporting effect. It is connected to the T-shaped supporting column 2 through the first locking bolt 12 to ensure that its position is fixed. A plurality of supporting caps 10 are symmetrically welded on the inner wall and plugged into the free end of the supporting frame rod 3 to provide additional supporting points, thereby enhancing the structural stability of the entire device and preventing the supporting frame rod 3 from breaking or deforming during use. The closed frame structure improves the overall rigidity of the device and extends its service life.

[0058] A casing sleeve method comprises the following steps:

[0059] S1: elastically sleeve the casing piece 6 onto the pulling ring 15, ensure that the pulling ring 15 can slide freely along the central axis direction of the sleeve piece 7, and use the locking outer ring 17 to fix the casing piece 6 onto the pulling ring 15;

[0060] S2: Turn on the power supply and start the driving motor 21. The output shaft of the driving motor 21 drives the pulling shaft 20 to rotate. The pulling shaft 20 is installed between the two ear plates 19 through the bearing to rotate smoothly.

[0061] S3: When the pulling shaft 20 rotates, the two symmetrical pulling ropes 16 begin to be wound, and the pulling ropes 16 pass through the rope threading holes 31, gradually transmitting the pulling force to the pulling ring 15. As the pulling ropes 16 are wound, the pulling ring 15 slides on the sleeve member 7, driving the casing member 6 to be evenly stretched;

[0062] S4: When the casing piece 6 is pulled, its inner wall is in frictional contact with the ball 29. The ball 29 is located in the rolling gap chamber 42 and can roll freely during the pulling process of the casing piece 6. The rolling of the ball 29 reduces the friction between the casing piece 6 and the end wall of the casing piece 7.

[0063] S5: When the ball 29 rolls in the rolling gap chamber 42, it drives the water in the water chamber 41 to flow out from the gap between the rolling gap chamber 42 and the ball 29, wetting the inner wall of the casing 6;

[0064] S6: The water in the water cavity 41 is sprayed to the humidifying cotton ring 30 in the form of fine water mist through the micron-sized water spray holes 34. The humidifying cotton ring 30 absorbs the water and transfers the water to the casing 6 through friction, further enhancing the wetting effect;

[0065] S7: When the casing piece 6 reaches the required length, the driving motor 21 is turned off and the rotation of the pulling shaft 20 is stopped. At this time, the pulling rope 16 is no longer wound, the pulling ring 15 stops sliding, and the casing piece 6 remains in the state after being pulled by the sleeve.

[0066] Working principle:

[0067] The casing sleeve method and device are as follows: the base support 1 is placed on a stable ground and the position is adjusted by the moving wheel 13. If it does not need to be moved, the moving wheel 13 can be lifted off the ground by adjusting the supporting feet 14 to ensure the stability of the equipment, and a T-shaped support column 2 is installed, and multiple support frame rods 3 are welded on both sides thereof. Multiple U-shaped extension frames 4 are arranged crosswise up and down and plugged into adjacent support frame rods 3 to form a stable frame structure, and a casing sleeve assembly 5 is installed inside each U-shaped extension frame 4, including a sleeve member 7, a pulling ring 15, a pulling rope 16 and other components.

[0068] Connect the water pipe 23 to an external water pump and water source to ensure that the water can enter the water cavity 41 of each casing piece 7 through the branch pipe 24, check whether the water inlet hole 32 and the micron-level water spray hole 34 are unobstructed, and ensure that the water can be evenly sprayed onto the inner wall of the casing piece 6.

[0069] The casing piece 6 is elastically sleeved on the pulling ring 15 to ensure that the pulling ring 15 can slide freely along the central axis direction of the sleeve piece 7. A silicone anti-skid ring 28 is bonded to the outer wall of the pulling ring 15 to increase the friction between the casing piece 6 and the pulling ring 15 to prevent sliding. The casing piece 6 is fixed to the pulling ring 15 using the locking outer ring 17. The specific operation is as follows: pull the positioning rod 40 to make the lower pressing block 26 close to the inner wall of the locking outer ring 17, and then sleeve the locking outer ring 17 on the outside of the pulling ring 15, loosen the positioning rod 40, and under the elastic force of the compression spring 39, the lower pressing block 26 automatically pops out and clamps the casing pulling and pressing end 27 to ensure that the casing piece 6 is firmly fixed. If more precise clamping is required, the position of the lower pressing block 26 can be adjusted by screwing the second locking bolt 25 to further tighten the casing piece 6.

[0070] Turn on the power supply and start the driving motor 21. The output shaft of the driving motor 21 drives the pulling shaft 20 to rotate. The pulling shaft 20 is installed between the two ear plates 19 through a bearing to ensure its smooth rotation. When the pulling shaft 20 rotates, the pulling rope 16 begins to be wound. The pulling rope 16 passes through the rope threading hole 31 and gradually transmits the pulling force to the pulling ring 15. As the pulling rope 16 is wound, the pulling ring 15 slides on the sleeve member 7, driving the casing member 6 to be evenly stretched.

[0071] When the casing piece 6 is pulled, its inner wall is in frictional contact with the ball 29. The ball 29 is located in the rolling gap chamber 42 and can roll freely during the pulling process of the casing piece 6. The rolling of the ball 29 reduces the friction between the casing piece 6 and the end wall of the sleeve piece 7, preventing the sleeve piece 7 from scratching the casing piece 6, and making the pulling process smoother.

[0072] The water pump delivers water to the branch pipe 24 through the water pipe 23, and then enters the water cavity 41 inside the sleeve member 7 through the water inlet hole 32. The water in the water cavity 41 is sprayed onto the inner wall of the casing member 6 in the form of fine water mist through the micron-sized water spray holes 34 to keep it moist. Alternatively, the humidifying cotton ring 30 is sleeved in the annular groove 33 to absorb water and transfer the water to the casing member 6 through friction, further enhancing the moistening effect.

[0073] When the ball 29 rolls in the rolling gap chamber 42, it drives the water in the water chamber 41 to flow out from the gap between the rolling gap chamber 42 and the ball 29, further moistening the inner wall of the casing 6. This design not only keeps the casing 6 moist, but also reduces friction through the flow of water, thereby preventing the occurrence of jamming.

[0074] The hydraulic damper 22 is fixed to the inner wall of the L-top cover 18, and its damping end abuts against the drive motor 21. The function of the hydraulic damper 22 is to provide shock absorption and buffering for the drive motor 21, reduce the vibration caused by the operation of the motor, and ensure the stability of the entire device. Through the buffering effect of the hydraulic damper 22, the noise can be effectively reduced and the service life of the equipment can be extended.

[0075] When the casing piece 6 reaches the desired length and shape, the driving motor 21 is turned off and the rotation of the pulling shaft 20 is stopped. At this time, the pulling rope 16 is no longer wound, the pulling ring 15 stops sliding, and the casing piece 6 remains in the pulled state. If it is necessary to remove the casing piece 6, the second locking bolt 25 can be screwed or the positioning rod 40 can be pulled to loosen the pressing block 26, release the clamping of the pulling and pressing end 27 of the casing, and remove the casing piece 6 to prepare for the next operation or replace it with a new casing piece 6.
