Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a docking device that is easy to disassemble and improves efficiency. Background Technology
[0002] In the daily operation of rolling mills, efficient maintenance and rapid replacement of parts are key to ensuring production continuity and improving production efficiency. As an important component of the rolling mill cooling system, the lower spray plate plays a vital role in the quality of the rolls and rolled products. However, the disassembly of the lower spray plate base during roll system replacement presents many challenges. The traditional method of connecting the lower spray plate lifting cylinder oil pipes mostly uses conventional joints. When the lower spray plate base needs to be disassembled for roll system replacement, this connection method reveals obvious drawbacks. On the one hand, the disassembly process of conventional joints is cumbersome, requiring workers to use various tools and spending a lot of time loosening and disassembling the joints, which greatly prolongs the downtime of roll system replacement and reduces production efficiency.
[0003] The existing process for disassembling the oil pipe on the lifting cylinder is extremely complicated. Maintenance personnel not only need to use a variety of tools such as wrenches and screwdrivers, but also need to deal with nuts and bolts of different specifications, loosening and removing the connecting parts one by one. Due to the compact layout of the rolling mill and the very limited operating space, maintenance personnel often have to operate in an extremely awkward posture, which further increases the difficulty of operation and time cost.
[0004] Therefore, there is an urgent need to provide a docking device that is easy to disassemble and improves efficiency to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a docking device that is easy to disassemble and improves efficiency.
[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing a docking device that is easy to disassemble and improves efficiency, including a lifting cylinder, wherein two threaded mounting pipes are threadedly connected to one side of the lifting cylinder, and a fixing pipe is fixedly connected to one side of each of the two threaded mounting pipes. Both of the fixed tubes are equipped with sealing gaskets inside, and both of the fixed tubes are equipped with docking components; Each of the docking components is equipped with an oil pipe, which enables the oil pipe to be quickly connected and secured.
[0007] The present invention is further configured such that: a connecting groove is provided inside both of the two fixed tubes, and both of the sealing gaskets fit into the connecting groove.
[0008] Through the above technical solution, the connecting groove provides a precise installation space for the sealing gasket. The matching size can firmly fix the sealing gasket in the preset position, preventing it from shifting, wrinkling or falling off during the insertion, rotation or squeezing of the connecting tube, ensuring that the sealing gasket is always in the core position of the sealing surface and plays an effective sealing role.
[0009] The present invention is further configured such that: the docking assembly includes mounting grooves at the upper and lower ends of the fixed tube; guide rods are fixedly connected between the inner walls of the two mounting grooves; fixed blocks are rotatably connected to the outer surfaces of the two guide rods; locking blocks are fixedly connected to the inner sides of the fixed blocks; pull rods are fixedly connected to the outer sides of the two fixed blocks; a connecting tube is slidably connected to the inner side of the fixed tube; guide grooves are provided at both the upper and lower ends of the connecting tube; an anti-detachment groove is provided on the side of the connecting tube near the guide groove; a first adjusting ring, a second adjusting ring, and a third adjusting ring are fixedly connected inside the connecting tube; and a locking sleeve is installed on the side of the connecting tube away from the guide groove.
[0010] The above technical solution involves first aligning the connecting pipe with the fixed pipe, then inserting the two guide grooves into the fixed pipe via locking blocks. Next, the connecting pipe is rotated 90°, causing the locking blocks to limit the connecting pipe's position via the anti-disengagement groove. Then, the pull rod is rotated counter-clockwise, causing the corresponding fixed block to rotate. Since the lateral distance of the fixed block is greater than the lateral distance of the anti-disengagement groove, the fixed block, while rotating, can press the connecting pipe towards the sealing gasket, significantly improving the sealing performance. Then, the oil pipe is slidably connected to the inside of the connecting pipe. Simultaneously, the locking sleeve is threaded to the outer wall of the connecting pipe, achieving the purpose of fixation. Furthermore, the first, second, and third adjusting rings are suitable for oil pipes of different sizes.
[0011] The present invention is further configured such that the inner surfaces of the plurality of mounting grooves are matched with the corresponding fixing blocks, and that every two fixing blocks are parallel to each other.
[0012] The above technical solution ensures that the fixing block is accurately installed and moves stably in the mounting groove, avoiding shaking or jamming caused by size mismatch, and provides a foundation for the subsequent cooperation between the locking block and the anti-disengagement groove.
[0013] The present invention is further configured such that the plurality of guide grooves and the two anti-detachment grooves are all matched with the corresponding locking blocks.
[0014] The above technical solution ensures that the locking block is fully engaged in the anti-disengagement groove, forming a firm axial limit, effectively preventing the connecting pipe from accidentally falling off, improving structural safety, and also avoiding stress concentration caused by excessive or insufficient local fit clearance, reducing the risk of component deformation and extending service life.
[0015] The present invention is further configured such that: one side of each of the two connecting pipes is provided with a threaded line, and the two locking sleeves are threadedly connected to the corresponding connecting pipes through the threaded lines.
[0016] Through the above technical solution, the threaded connection achieves tight engagement through the axial force generated by the spiral structure, which can firmly fix the locking sleeve and the connecting pipe. Compared with other connection methods such as snap-fit, it can withstand greater axial tension and vibration impact, effectively preventing the oil pipe from loosening or falling off during operation.
[0017] The present invention is further configured such that the inner diameters of the first adjusting ring, the second adjusting ring, and the third adjusting ring are arranged in ascending order.
[0018] Through the above technical solution, the first, second, and third adjusting rings with different inner diameters can be matched with oil pipes of different diameters. By selecting the first, second, and third adjusting rings with corresponding inner diameters to cooperate with the oil pipes, stable connection of oil pipes of various specifications can be achieved without designing separate docking components for oil pipes of different sizes, which greatly improves the versatility and applicability of the device.
[0019] The beneficial effects of this utility model are as follows: 1. This utility model achieves rapid positioning by setting up a docking component and using the precise cooperation between the guide groove and the locking block, and then achieves tight fixation by rotating the pull rod. The entire process does not require cumbersome bolt tightening or welding operations. Disassembly can be performed by reversing the operation to quickly separate the components. Compared with traditional flange connections or welding structures, it saves a lot of disassembly and assembly time. 2. By setting a fixed tube and a sealing gasket, when the connecting tube is squeezed towards the sealing gasket by the fixed block, the sealing gasket will undergo elastic deformation due to the force, filling the gap between the fixed tube and the connecting tube, forming a reliable sealing barrier, which can effectively avoid the waste of resources caused by media leakage.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0023] Please see Figure 1 - Figure 5A docking device that facilitates disassembly and improves efficiency includes a lifting cylinder 1. Two threaded mounting tubes 2 are threadedly connected to one side of the lifting cylinder 1. A fixing tube 3 is fixedly connected to one side of each of the two threaded mounting tubes 2. A sealing gasket 4 is installed inside each of the two fixing tubes 3. A connecting groove is formed inside each of the two fixing tubes 3, and the two sealing gaskets 4 fit snugly into the connecting groove. The connecting groove provides precise installation space for the sealing gasket 4. The fitting dimensions firmly fix the sealing gasket 4 in a preset position, preventing it from shifting, wrinkling, or falling off during insertion, rotation, or compression of the connecting tube 506. This ensures that the sealing gasket 4 is always in the core position of the sealing surface, effectively sealing the device. Both fixing tubes 3 have... A docking assembly 5 is installed, comprising mounting grooves 501 at the upper and lower ends of a fixed tube 3. Guide rods 502 are fixedly connected between the inner walls of the two mounting grooves 501. Fixing blocks 503 are rotatably connected to the outer surfaces of the two guide rods 502. Locking blocks 504 are fixedly connected to the inner sides of the fixing blocks 503. Pull rods 505 are fixedly connected to the outer sides of the two fixing blocks 503. A connecting tube 506 is slidably connected to the inner side of the fixed tube 3. Guide grooves 507 are provided at both the upper and lower ends of the connecting tube 506. An anti-detachment groove 508 is provided on the side of the connecting tube 506 near the guide grooves 507. A first adjusting ring 509, a second adjusting ring 5010, and a... are fixedly connected inside the connecting tube 506. The third adjusting ring 5011 has a locking sleeve 5012 installed on the side of the connecting pipe 506 away from the guide groove 507. First, align the connecting pipe 506 with the fixed pipe 3. Then, the two guide grooves 507 will be inserted into the fixed pipe 3 through the locking block 504. At this time, rotate the connecting pipe 506 90° so that the locking block 504 limits the connecting pipe 506 through the anti-disengagement groove 508. Then, rotate the pull rod 505 counterclockwise so that the pull rod 505 drives the corresponding fixed block 503 to rotate. Since the lateral distance of the fixed block 503 is greater than the lateral distance of the anti-disengagement groove 508, the fixed block 503 can move the connecting pipe 506 towards the sealing gasket 4 while rotating. The compression process significantly improves the sealing performance. Then, the oil pipe 6 is slidably connected to the inside of the connecting pipe 506. At the same time, the locking sleeve 5012 is threaded to the outer wall of the connecting pipe 506 to achieve the purpose of fixation. The first adjusting ring 509, the second adjusting ring 5010, and the third adjusting ring 5011 can be used for oil pipes 6 of different sizes. The inner surfaces of multiple mounting grooves 501 are matched with the corresponding fixing blocks 503, and every two fixing blocks 503 are parallel to each other. This ensures that the fixing blocks 503 are accurately installed and move stably in the mounting grooves 501, avoiding shaking or jamming caused by size mismatch, and providing a basis for the subsequent cooperation between the locking block 504 and the anti-disengagement groove 508. like Figure 2 , Figure 4 and Figure 5As shown, each of the docking components 5 is equipped with an oil pipe 6. The docking component 5 can quickly dock and fix the oil pipe 6. Multiple guide grooves 507 and two anti-disengagement grooves 508 are matched with corresponding locking blocks 504. This ensures that the locking blocks 504 are fully engaged in the anti-disengagement grooves 508, forming a firm axial limit, effectively preventing the connecting pipe 506 from accidentally falling off, improving structural safety, and also avoiding stress concentration caused by excessive or insufficient local fit clearance, reducing the risk of component deformation and extending service life. Both connecting pipes 506 have threads on one side, and the two locking sleeves 5012 are threaded to the corresponding connecting pipes 506 through the threads. The threaded connection achieves tight engagement through the axial force generated by the spiral structure, which can lock the locking sleeves 5012. 2. It is firmly fixed to the connecting pipe 506. Compared with connection methods such as snap-fit, it can withstand greater axial tensile force and vibration impact, effectively preventing the oil pipe 6 from loosening or falling off during operation. The inner diameters of the first adjusting ring 509, the second adjusting ring 5010 and the third adjusting ring 5011 are arranged in ascending order. The first adjusting ring 509, the second adjusting ring 5010 and the third adjusting ring 5011 with different inner diameters can be matched with oil pipes 6 of different diameters. By selecting the first adjusting ring 509, the second adjusting ring 5010 and the third adjusting ring 5011 with the corresponding inner diameter to cooperate with the oil pipe 6, a stable connection of oil pipes 6 of various specifications can be achieved. There is no need to design a separate docking component 5 for oil pipes 6 of different sizes, which greatly improves the versatility and applicability of the device.
[0024] In use, the connecting pipe 506 is first aligned with the fixing pipe 3. Then, the two guide grooves 507 are inserted into the fixing pipe 3 via the locking block 504. Next, the connecting pipe 506 is rotated 90°, causing the locking block 504 to limit its position via the anti-disengagement groove 508. Then, the pull rod 505 is rotated counterclockwise, causing the corresponding fixing block 503 to rotate. Since the lateral distance of the fixing block 503 is greater than the lateral distance of the anti-disengagement groove 508, the fixing block 503 is further secured. While the fixed block 503 rotates, it can squeeze its connecting pipe 506 towards the sealing gasket 4, which greatly improves the sealing performance. Then, the oil pipe 6 is slidably connected to the inside of the connecting pipe 506. At the same time, the locking sleeve 5012 is threaded to the outer wall of the connecting pipe 506 to achieve the purpose of fixing. The first adjusting ring 509, the second adjusting ring 5010 and the third adjusting ring 5011 can be used for oil pipes 6 of different sizes. Finally, the oil flows into the lifting cylinder 1 through the oil pipe 6 and the threaded mounting pipe 2.
