Description

Technical Field

[0001] This utility model relates to the field of MPP corrugated pipe technology, and specifically to a docking device for MPP corrugated pipes. Background Technology

[0002] When connecting MPP corrugated pipes to external pipelines, they are generally connected directly using items such as sleeves and flanges. Although the former method is more convenient, it has poor stability because the pipe itself may vibrate due to mechanical force or other external forces. The latter method requires the simultaneous installation and tightening of several bolts, making subsequent disassembly and maintenance more troublesome.

[0003] According to patent document CN110281201B, a high-efficiency docking device for corrugated pipes is disclosed, including semi-circular clamps distributed on the left and right and fitted onto the corrugated pipe. A telescopic connecting rod is provided between the ends of the two semi-circular clamps. The telescopic connecting rod is made by inserting a left square rod and a right square tube. A docking mechanism and a power mechanism are provided on the telescopic connecting rod. The docking mechanism includes a rectangular short tube fixed on the left square rod and with its bottom surface flush with it, and a rack fixed on the upper end face of the right square tube and extending into the rectangular short tube. A rotating shaft passes through the front and rear side walls of the rectangular short tube. A rotating plate located outside the rectangular short tube, an external ratchet located outside the rotating plate, and an internal gear located inside the rectangular short tube and meshing with the rack are fixed on the rotating shaft.

[0004] Currently, traditional MPP bellows docking devices are not suitable for use because the sealing devices used for bellows docking do not enhance the practicality of the bellows, make it difficult to dock two bellows, and do not improve the sealing performance of the bellows docking.

The setting of the connecting mechanism 6 facilitates the connection of the bellows and improves the sealing performance of the bellows connection.

[0027] Working Principle: First, a connecting pipe 2 is installed on one side of the pipe body 1. To ensure the stability and reliability of the connection, a limiting ring 3 is installed on the outer wall of the connecting pipe 2. On the outer wall of the limiting ring 3, a sleeve 41 and a sleeve 44 can be easily disassembled and connected to provide a stable installation position. In addition, another connecting pipe 5 is fixedly connected to the other side of the pipe body 1 away from the connecting pipe 2. To further enhance the flexibility and adaptability of the device, a connecting mechanism 6 is slidably connected to the outer wall of the connecting pipe 5. The inner wall of the sleeve 41 fits tightly with the outer wall of the limiting ring 3, ensuring a seamless connection between the two. To further enhance the stability of the structure, fixing devices are provided at both the upper and lower ends of the sleeve 41. A support block 43 is also provided on one side of the ear 42 and the sleeve 41. A screw 45 can be inserted and connected to the inner wall of the support block 43. The outer wall of the screw 45 is threaded and can be threaded to connect with the nut 46, thereby realizing the fine adjustment of the telescopic mechanism 4. One end of the screw 45 is fixedly connected to a telescopic tube 47, and the inner wall of the telescopic tube 47 is threaded to a double-ended lead screw 48. A rotating block 49 is fixedly connected to the middle of the double-ended lead screw 48, so that the entire telescopic mechanism 4 can flexibly perform telescopic and rotational operations. In order to further ensure the stability and reliability of the telescopic mechanism 4, a limiting groove 410 is specially opened on the inner side wall of the sleeve 41. In addition, both the upper and lower ends of the sleeve 41 are connected to one end of the fixed ear 42. The fixed connection ensures the stability of the entire structure. To improve the adaptability and flexibility of the device, two telescopic tubes 47 are provided, and these two telescopic tubes 47 are symmetrically arranged on both sides of the double-ended screw 48, and can be well adapted and matched with each other. One side of the connecting tube 1 2 is fixedly connected to one side of the tube body 1, ensuring a firm connection between the connecting tube 1 2 and the tube body 1. The inner wall of the limiting ring 3 is fixedly connected to the outer wall of the connecting tube 1 2, further enhancing the stability and reliability of the connection. This arrangement can meet the needs of various engineering and industrial applications. One side of the limiting block 61 is fixedly connected to one side of the connecting tube 2 5. A connecting sleeve 62 is provided on the top of one side of the limiting block 61, and the inner wall of the connecting sleeve 62 is provided with an internal thread. A sealing gasket 64 is adhered to one side of the limiting block 61. The top of one side of the limiting block 61 is movably connected to one side of the connecting sleeve 62. The inner wall of the connecting sleeve 62 is embedded and connected to the outer wall of the internal thread 63. The connecting sleeve 62 is fitted onto the outer wall of the second connecting pipe 5, and the inner diameter of the connecting sleeve 62 is adapted to the outer diameter of the second connecting pipe 5. In use, rotating the rotating block 49 drives the double-ended screw 48 to rotate. The rotation of the double-ended screw 48 drives the two telescopic pipes 47 to move towards each other. The movement of the telescopic pipes 47 drives the screw 45 to move. The movement of the screw 45 drives the nut 46 and the first sleeve 41 or the second sleeve 44 to move until the two pipes are tightly fitted. Then, rotating the connecting sleeve 62 drives the internal thread 63 to rotate.The internal thread 63 rotates to connect with the external thread on the inner wall of the other connecting sleeve 62 until the two connecting sleeves 62 are tightly fitted, completing the docking. The telescopic mechanism 4 facilitates the docking of the two MPP bellows, and the connecting mechanism 6 facilitates sealing at the docking point of the two MPP bellows.

[0028] Then, by firmly connecting one end of the limiting block 61 to the corresponding side of the connecting pipe 5, a connecting sleeve 62 is provided at the top of the other end of the limiting block 61. The inner wall of this connecting sleeve 62 is provided with an internal thread 63. In addition, a sealing gasket 64 is attached to the other end of the limiting block 61 to ensure the sealing performance of the connection. The top end of the connecting sleeve 62 is connected to the corresponding end of the limiting block 61 by a movable connection, allowing the connecting sleeve 62 to move relative to the limiting block 61 to a certain extent. The inner wall of the connecting sleeve 62 is tightly embedded with the outer wall of the internal thread 63, forming a nested connection structure. The connecting sleeve 62 is fitted onto the outer wall of the connecting pipe 5, and the inner diameter of the connecting sleeve 62 is perfectly matched with the outer diameter of the connecting pipe 5, ensuring the tightness and stability of the connection. In use, rotating the rotating block 49 drives the double-ended screw 48 to rotate. The rotation of the double-ended screw 48 drives the two telescopic tubes 47 to move relative to each other or in opposite directions. The relative movement of the two telescopic tubes 47 compresses and fixes the corrugated pipe, while the in opposite movement of the two telescopic tubes 47 releases the compression on the corrugated pipe. The expansion joint 47 is press-fixed to facilitate the connection of the bellows. The movement of the telescopic tube 47 moves the screw 45, which in turn moves the nut 46 to rotate on the inner wall of the support block 43. Simultaneously, the screw 45 moves the sleeve 44, causing the sleeve 41 and sleeve 44 to limit the bellows. The inner wall of the sleeve 41 is also in close contact with the outer wall of the limiting ring 3, improving the stability of the expansion mechanism 4 during use. The expansion mechanism 4 facilitates the limiting and fixing of the bellows and also facilitates the connection of the bellows, improving the sealing performance of the bellows connection. The practicality of the bellows is improved. The inner wall of the connecting sleeve 62 is provided with an internal thread 63, which facilitates the connection of the bellows by threaded connection and improves the stability of the bellows connection. At the same time, a sealing gasket 64 is bonded to one side of the limiting block 61, which improves the sealing performance of the bellows connection. The setting of the connecting mechanism 6 facilitates the connection of the bellows and improves the sealing performance of the bellows connection. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
