Description

Technical Field

[0001] This application belongs to the field of sleeve replacement technology, specifically relating to a rubber sleeve replacement device. Background Technology

[0002] In industrial production, rubber sleeves are commonly used to reduce friction, protect equipment components, or serve as sealing elements. Especially in industries such as steel, papermaking, and textiles, replacing rubber sleeves is an important part of routine maintenance.

[0003] In the steel metallurgical industry, the coiler is one of the key pieces of equipment on hot-rolled or cold-rolled strip steel production lines. The rubber sleeve, installed on the coiler's mandrel, primarily reduces rigid contact between the strip and the mandrel, preventing crease defects in the coil. Existing rubber sleeve replacement devices weigh up to 200 kg, and the sleeve replacement process is complex. An overhead crane must first lift the device onto the unloading trolley. After removing the sleeve, the device with the old sleeve must be lifted back to its original position. Then, the replacement device with the new sleeve is lifted onto the trolley. After replacing the sleeve, the device is finally lifted back to its original position. This process takes at least 50 minutes.

[0004] When using the existing replacement device to replace rubber sleeves, the production line needs to slow down and wait when there are many changes in specifications, which seriously affects the production rhythm. If an accident occurs in a certain winding machine, it is not possible to switch to another winding machine in time. It is easy to return for repair due to the mismatch of inner diameter, which may even lead to the shutdown of the production line. Utility Model Content

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] This utility model discloses a rubber sleeve replacement device, which can solve the technical problem that existing tool replacements affect the production rhythm, thereby improving work efficiency and safety.

[0036] The technical solution of this application will be described in detail below through specific embodiments:

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4 According to a first aspect embodiment of this application, a rubber sleeve replacement device is provided, which includes a drive device 100, a support plate 200, an end hook 300, and two side baffles 400. The drive device 100 includes a drive structure 110 and a lifting structure 120, with the lifting structure 120 mounted on top of the drive structure 110. The support plate 200 is connected to the lifting structure 120 via a positioning rod 220. The end hook 300 is mounted on the first end of the support plate 200, and the height of the end hook 300 is less than the wall thickness of the rubber sleeve 500. The two side baffles 400 are respectively mounted on both sides of the support plate 200.

[0038] The drive structure 110 provides power, while the lifting structure 120 is installed on top of the drive structure 110 to realize the lifting function of the device. The height of the device can be easily adjusted by the operation of the drive device 100 to adapt to different working environments. The support plate 200, as the main load-bearing component of the device, is connected to the lifting structure 120 via a positioning rod 220. The design of the positioning rod 220 ensures a stable connection between the support plate 200 and the lifting structure 120, preventing swaying or detachment during lifting. An end hook 300 is installed at the first end of the support plate 200, and its height is less than the wall thickness of the rubber sleeve 500. This design allows the end hook 300 to easily hook onto the inner wall of the rubber sleeve 500, thereby enabling the gripping and replacement of the sleeve. Simultaneously, because the height of the end hook 300 is less than the sleeve wall thickness, it will not damage the sleeve. Two side baffles 400 are respectively installed on both sides of the support plate 200 to prevent the rubber sleeve 500 from rolling or falling during replacement. The design of the side baffle 400 increases the stability of the device and ensures the safe replacement process.

[0039] The drive structure 110 can be a trolley, and the lifting structure 120 can be an electric hoist and a chain. Of course, the lifting structure 120 can also be a hydraulic cylinder and piston rod.

[0040] The rubber sleeve replacement device disclosed in this embodiment has a stable structure and is easy to operate, reducing the risk of manual operation and improving the safety of the replacement process. Through the cooperation of the automated drive device 100 and the lifting structure 120, the rapid replacement of the rubber sleeve 500 is achieved, greatly improving work efficiency. Since components such as the support plate 200, end hook 300, and side baffle 400 can be adjusted and replaced according to actual needs, the device provided by this utility model has strong adaptability and can be applied to the replacement of rubber sleeves 500 of different sizes and specifications.

[0041] When replacing the rubber sleeve 500, first place the support plate 200 at the position of the rubber sleeve 500 to be replaced, and adjust the position of the support plate 200 using the drive device 100 so that the support plate 200 is directly below the rubber sleeve 500. Then, start the drive device 100, causing the lifting structure 120 to lift the support plate 200 until the support plate 200 abuts against the bottom outer wall of the rubber sleeve 500. At this point, the rubber sleeve 500 can be separated from the winding machine core shaft, and then the lifting structure 120 lowers the support plate 200 and the rubber sleeve 500.

[0042] After replacing the rubber sleeve 500 on the support plate 200, use the lifting structure 120 again to raise the support plate 200 until the rubber sleeve 500 comes into contact with the winding machine core shaft. At this point, install the rubber sleeve 500 onto the winding machine core shaft, and finally remove the rubber sleeve replacement device.

[0043] In one embodiment, the drive structure 110 is provided with at least two positioning holes 130. The bottom of the support plate 200 is provided with a plurality of positioning rods 220, the number of positioning rods 220 being equal to the number of positioning holes 130, and each positioning rod 220 is provided in a one-to-one correspondence with each positioning hole 130.

[0044] At least two positioning holes 130 should be provided on the drive structure 110. These positioning holes 130 can be evenly distributed at appropriate positions on the drive structure 110 to ensure the balance and stability of the support plate 200. The number and position of the positioning holes 130 should be determined according to actual needs and the size of the drive structure 110. The bottom of the support plate 200 should be provided with a number of positioning rods 220 equal to the number of positioning holes 130. These positioning rods 220 should be set one-to-one with the positioning holes 130. The length and diameter of the positioning rods 220 should be determined according to the size of the positioning holes 130 and the weight of the support plate 200 to ensure that they can bear the weight of the support plate 200 and remain stable during lifting. The positioning rods 220 and the positioning holes 130 can be fitted with a sliding fit or a clearance fit. A sliding fit can provide better stability and accuracy, but may require more precise machining and installation. A clearance fit is easier to achieve, but may require fine-tuning during lifting to ensure the stability of the support plate 200.

[0045] The one-to-one correspondence between the positioning hole 130 and the positioning rod 220 ensures the stability of the support plate 200 during the lifting process and prevents it from affecting the accuracy of the replacement operation due to shaking or displacement.

[0046] The design of the positioning hole 130 and the positioning rod 220 allows for positional adjustment according to actual needs to accommodate the replacement requirements of rubber sleeves 500 of different sizes and specifications.

[0047] In one embodiment, two positioning rods 220 are provided, and the two positioning rods 220 are spaced apart along the length direction of the support plate 200.

[0048] Two positioning rods 220 are spaced apart along the length of the support plate 200 to form a stable support structure, preventing the support plate 200 from tilting or twisting during lifting, thereby ensuring the stability and safety of the replacement operation.

[0049] Two positioning rods 220 are sufficient to ensure the stability of the support plate 200. Of course, in other embodiments, it is also possible to provide more positioning rods 220 and positioning holes 130.

[0050] In one embodiment, one positioning rod 220 is located near the second end of the support plate 200, and the other positioning rod 220 is located between the first end and the middle of the support plate 200.

[0051] Two positioning rods 220 are arranged in a specific layout—one positioning rod 220 is located near the second end of the support plate 200 (the end away from the end hook 300), and the other positioning rod 220 is located between the first end (the end where the end hook 300 is mounted) and the middle of the support plate 200. This layout ensures the balance and stability of the support plate 200 during lifting and lowering. The positioning rod 220 near the second end provides rear-end support to prevent the support plate 200 from tilting backward during lifting and lowering; while the positioning rod 220 located between the first end and the middle provides front-end stabilizing support to prevent the support plate 200 from tilting forward or twisting during lifting and lowering.

[0052] With the support of two positioning rods 220, the force distribution on the support plate 200 is more even during the lifting process. This force distribution helps reduce the risk of structural damage caused by excessive force at a single point, and improves the overall stability and durability of the device.

[0053] In one embodiment, the support plate 200 includes a main body and two extensions 210, which are located on opposite sides of the main body. An end hook 300 is disposed at one end of the main body, and two side baffles 400 are disposed corresponding to the two extensions 210, with the side baffles 400 disposed at the end of the extension 210 away from the main body.

[0054] In the rubber sleeve replacement device, the design of the support plate 200 is crucial. It must not only provide stable support, but also facilitate operation and adapt to rubber sleeves 500 of different sizes.

[0055] The support plate 200, consisting of the main body and two extensions 210, has a more stable structure and can withstand greater weight and force. This stability is crucial for ensuring the safety and accuracy of the rubber sleeve 500 during replacement.

[0056] In addition, the extension 210 ensures that the main body of the support is narrow, which reduces the overall weight of the support plate 200 and makes it easier for workers to handle.

[0057] In one embodiment, the distance between the two side baffles 400 is equal to the diameter of the rubber sleeve 500. Matching the distance between the side baffles 400 to the diameter of the rubber sleeve 500 ensures that the side baffles 400 fit snugly against the sides of the sleeve. This snug fit not only helps prevent the sleeve from rolling or falling off during replacement but also reduces friction and wear between the sleeve and the side baffles 400.

[0058] See Figure 3 In one embodiment, the farthest distance between the two extensions 210 is equal to the diameter of the rubber sleeve 500, and the side baffle 400 is arranged perpendicular to the extensions 210. Matching the farthest distance between the two extensions 210 with the diameter of the rubber sleeve 500 ensures that the rubber sleeve 500 is precisely supported on the support plate 200.

[0059] Of course, making the side baffle 400 perpendicular to the support plate 200 is only one implementation method in this embodiment. See also... Figure 5 and Figure 6 In other embodiments, tilting the side baffle 400 relative to the support plate 200 can also ensure that the side baffle 400 restricts the rubber sleeve 500 to prevent the rubber sleeve 500 from rolling on the support plate 200. The side baffle 400 can be tilted inward or outward relative to the support plate 200.

[0060] In one embodiment, the height of the side baffle 400 is greater than or equal to the radius of the rubber sleeve 500. This effectively prevents the sleeve from rolling horizontally. This design ensures the stability of the sleeve during replacement and reduces accidents and safety hazards caused by rolling.

[0061] In one embodiment, the extension 210 is located at the midpoint of the support plate 200 along its length. When the extension 210 is at the midpoint of the support plate 200 along its length, the rubber sleeve 500 is placed at the center of the support plate 200, ensuring that the sleeve is subjected to uniform force during replacement. This balanced force distribution helps reduce bending and deformation of the support plate 200, improving overall stability and durability.

[0062] In one embodiment, the length of the side baffle 400 is equal to the length of the extension 210. When the length of the side baffle 400 matches the length of the extension 210, it ensures that the pressure on the rubber sleeve 500 on the support plate 200 is evenly distributed. This design helps reduce deformation of the support plate 200 and the side baffle 400, improving the stability and durability of the overall structure.

[0063] Through the above embodiments, this application has the following beneficial effects or advantages: The rubber sleeve replacement device disclosed in this application has a stable structure and is easy to operate, reducing the risk of manual operation and improving the safety of the replacement process. The entire device can be made of 10mm thick steel plate, weighing only about 20kg, and can be easily handled manually, eliminating the need for two lifting steps in traditional devices. The device is fixed to the unloading trolley by fixing pins, and the rubber sleeve 500 is directly pulled out or pushed in using the end face hook. The side baffles 400 effectively prevent the sleeve from rolling. The entire process is simple and quick, greatly improving replacement efficiency. Since components such as the support plate 200, end hook 300, and side baffles 400 can be adjusted and replaced according to actual needs, the device provided by this utility model has strong adaptability and can be applied to the replacement of rubber sleeves 500 of different sizes and specifications.
