Description
Technical Field
[0001] This utility model relates to the field of pipeline connection technology, and in particular to a rapid connection device for long pipe connections. Background Technology
[0002] In the field of building construction, whether it is the installation of water and gas supply pipelines in high-rise buildings or the laying of connecting pipes for large structural components in bridge engineering, long pipes need to be precisely connected to ensure the normal operation of the system. In the petrochemical industry, the construction of long-distance transmission pipelines and the assembly of internal pipelines in chemical equipment have extremely high requirements for the sealing and stability of long pipe connections.
[0003] The long pipe docking device mainly consists of positioning, adjustment, and connection mechanisms. The positioning mechanism stabilizes the long pipe and precisely centers it using high-precision clamps and centering chucks. The adjustment mechanism uses a screw and nut pair with a motor to achieve horizontal and vertical adjustment, and uses a hydraulic or pneumatic swing cylinder to complete the angle adjustment. The connection mechanism includes welding components such as arc welding robots and flange connection components such as electric wrenches. During operation, the long pipe is first fixed and initially positioned by the positioning mechanism. Then, the adjustment mechanism finely adjusts the position and angle of the long pipe according to preset parameters to ensure precise alignment of the pipe ends. Finally, the connection mechanism performs the operation according to the docking method (welding or flange connection) to achieve precise docking of the long pipe.
[0004] In various engineering scenarios today, some long pipe connection devices involve cumbersome and complex processes when performing pipeline connection tasks. From the initial pipe alignment to the operation of multiple sealing steps, and then to the fastening of the connection parts, each step requires a lot of manpower and time. For example, traditional devices often require manual repeated calibration of the pipe position, multiple application of sealing material and difficulty in ensuring uniformity, and the operation is even more time-consuming when using bolts and nuts to tighten the connection. Therefore, a long pipe quick connection device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a quick docking device for long pipes, which aims to improve the problem of cumbersome operation when docking long pipes in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A quick-connection device for long connectors includes a fixed shell. An adjustment assembly is installed inside the fixed shell. Connecting connector 1 and connecting connector 2 are fixedly connected to the outside of the adjustment assembly. Connecting pipe 1 and connecting pipe 2 are slidably connected inside each of the connecting pipes. Sliding teeth are fixedly connected to the outside of both connecting pipe 1 and connecting pipe 2. Sliding grooves are opened inside both connecting pipe 1 and connecting pipe 2. The outside of two sliding teeth slides within the two sliding grooves. Sealing gaskets are fixedly connected inside both connecting pipe 1 and connecting pipe 2. A control assembly is installed on the outside of both connecting pipe 1 and connecting pipe 2.
[0008] As a further description of the above technical solution:
[0009] The control component includes two rotating rings, the outer sides of which are threadedly connected to the outer sides of the first coupling pipe and the second coupling pipe, respectively, and the inner sides of each of the two rotating rings are fixedly connected to a driven ring.
[0010] As a further description of the above technical solution:
[0011] The driven ring has a groove inside, and the outer part of the sliding tooth is slidably connected to the inside of the groove.
[0012] As a further description of the above technical solution:
[0013] The outer side of the driven ring contacts the outer side of the sliding tooth, and the adjacent sides of the first and second connecting pipes respectively contact the distant sides of the two sealing gaskets.
[0014] As a further description of the above technical solution:
[0015] The outer side of the first connecting pipe is slidably connected to the inside of the driven ring, and both the first connecting pipe and the second connecting pipe have threaded grooves on their outer sides.
[0016] As a further description of the above technical solution:
[0017] The adjusting assembly includes an outer ring, the outer ring being fixedly connected to the inside of the fixed housing, and an inner ring being rotatably connected to the inside of the outer ring. The outer ring is fixedly connected to the inside of the second coupling pipe, and the outer ring is fixedly connected to the inside of the first coupling pipe.
[0018] As a further description of the above technical solution:
[0019] The outer side of the connecting tube is in contact with the inner side of the fixed shell, and the inner side of the outer ring is spherical;
[0020] As a further description of the above technical solution:
[0021] The outer surface of the inner ring is spherical, and the outer surfaces of the two driven rings are in contact with the outer surfaces of the first and second connecting pipes, respectively.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the operator slides the pipe to be connected into the corresponding connecting pipe. After the sliding teeth slide into place along the specific sliding groove, the operator rotates the rotating ring. Through the engagement with the threaded groove, the rotating ring moves and rotates, changing the position of the sliding groove until the driven ring tightly fits the sliding teeth, achieving a tight fit between the connecting pipe and the sealing gasket, thus achieving a sealed connection. When disassembling, the rotating ring is rotated in the opposite direction to connect the two sliding grooves, allowing the connecting pipe to be easily removed. This process greatly reduces the time spent on pipe connection, has fewer operation steps, and significantly improves work efficiency.
[0024] 2. In this utility model, after the connecting pipe is successfully connected, the connecting pipe is rotated, and the inner ring connected to it will rotate within the outer ring and the fixed shell. The fixed shell restricts the rotation range, thereby breaking through the limitations of traditional straight-line connection, enabling the device to flexibly adapt to the needs of pipe connection at different angles, and significantly improving the practicality of the entire connection device in complex installation environments.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a long pipe quick docking device, including a fixed shell 1. The fixed shell 1 plays a role in stable support and limiting in the entire docking device. The fixed shell 1 provides an installation base for the internal structure. An adjustment component is provided inside the fixed shell 1. The adjustment component is the key part to realize the relative position adjustment of the first docking pipe 4 and the second docking pipe 5. The first docking pipe 4 and the second docking pipe 5 are fixedly connected to the outside of the adjustment component. The first docking pipe 4 and the second docking pipe 5 are important components for connecting the long pipe. The first docking pipe 4 and the second docking pipe 2 directly cooperate with the connecting pipe to be docked. The first connecting pipe 6 and the second connecting pipe 2 13 are slidably connected inside the first docking pipe 4 and the second docking pipe 2, respectively. The first connecting pipe 6 and the second connecting pipe 2 13 are the long pipe parts that need to be docked. The first connecting pipe 6 and the second connecting pipe 2 13 slide inside the docking pipe to realize the connection.
[0033] Both connecting pipe 1 (6) and connecting pipe 2 (13) are externally fixedly connected with sliding teeth 8. The sliding teeth 8 cooperate with the internal structure of the connecting pipe to achieve positioning and locking. Both connecting pipe 1 (4) and connecting pipe 2 (5) have internal sliding grooves 12. The two sliding teeth 8 slide within the two sliding grooves 12, which provide a track for the sliding teeth 8 and guide their movement. Both connecting pipe 1 (4) and connecting pipe 2 (5) are internally fixedly connected with sealing gaskets 14. Sealing gaskets 14 are key structures for achieving a sealing effect. When the connecting pipes and connecting pipes are mated... To prevent fluid leakage, the connecting pipes are tightly fitted to the outside. Both connecting pipe 1 4 and connecting pipe 2 5 are equipped with control components. The control components are used to control the docking and disassembly process of the connecting pipes, ensuring the convenience and stability of operation. The control components include two rotating rings 11, which are the operating parts of the control components. The operator rotates the two rotating rings 11 to realize the subsequent connection and disassembly actions. Their external parts are threaded to the outside of connecting pipe 1 4 and connecting pipe 2 5, respectively. This threaded connection method allows the rotating rings 11 to move outside the connecting pipes and transmit power.
[0034] Both rotating rings 11 have driven rings 9 fixedly connected inside. The driven rings 9 move with the rotating rings 11, further transmitting power and controlling the sliding teeth 8. A groove 7 is formed inside the driven ring 9, and the outer surface of the sliding teeth 8 is slidably connected to the inside of the groove 7. The groove 7 engages with the sliding teeth 8, guiding the sliding of the sliding teeth 8 during connection and restricting the movement of the sliding teeth 8 when locked. The outer surface of the driven ring 9 contacts the outer surface of the sliding teeth 8; this contact achieves control and locking of the sliding teeth 8. The connecting pipe 4 connects to the... The adjacent side of the second connecting pipe 5 contacts the opposite side of the two sealing gaskets 14 respectively. This structure ensures that the sealing gaskets 14 are properly squeezed during docking, thereby achieving a good sealing effect. The external sliding connection of the first connecting pipe 6 is inside the driven ring 9. The driven ring 9 provides guidance and certain support for the sliding of the first connecting pipe 6. Both the first connecting pipe 4 and the second connecting pipe 5 have threaded grooves 10 on their external sides. The threaded grooves 10 are threadedly connected to the rotating ring 11, which is the key structure for realizing the movement of the rotating ring 11 outside the connecting pipe.
[0035] Reference Figure 1 , Figure 2 and Figure 4 The adjusting assembly includes an outer ring 3, which is externally and fixedly connected to the inside of the fixed shell 1. The outer ring 3 serves as a basic support and rotation track within the adjusting assembly. Fixed within the fixed shell 1, the outer ring 3 provides support for the rotation of the inner ring 2. The inner ring 2 is rotatably connected to the inside of the outer ring 3. The inner ring 2 is the key structure for achieving the rotation of the first coupling pipe 4. The inner ring 2 can rotate within the outer ring 3, thereby driving the first coupling pipe 4 to rotate. The second coupling pipe 5 is externally and fixedly connected to the inside of the outer ring 3, and the first coupling pipe 4 is externally and fixedly connected to the inside of the inner ring 2. This connection method makes the second coupling pipe 5 relatively fixed. 4 can rotate by rotating the inner ring 2. The outside of the coupling pipe 4 contacts the inside of the fixed shell 1. The fixed shell 1 restricts the rotation range of the coupling pipe 4 to ensure its rotation stability and controllability. The inside of the outer ring 3 is spherical, and the outside of the inner ring 2 is spherical. This spherical structure design allows the inner ring 2 to rotate in multiple directions within the outer ring 3, breaking through the limitation of traditional docking devices that can only dock in a straight line. The outside of the two driven rings 9 contacts the outside of the coupling pipe 4 and the coupling pipe 5 respectively. This contact ensures the stability between the driven rings 9 and the coupling pipe, so that the power can be effectively transmitted.
[0036] Working principle: When connecting pipes, the operator can slide the connecting pipe 2 13 and connecting pipe 1 6 into the connecting pipe 2 5 and connecting pipe 1 4 respectively. At this time, the sliding tooth 8 will first slide inside the sliding groove 1 7. When the sliding tooth 8 is fully slid into the sliding groove 2 12, the operator can rotate the rotating ring 11. The rotating ring 11 moves outside the driven ring 9 through the meshing connection with the threaded groove 10. The driven ring 9 will rotate with the movement of the rotating ring 11, thereby changing the position of the sliding groove 1 7 until the driven ring 9 is tightly closed. When the outer surface of the sliding tooth 8 is tightly closed, the outer surfaces of connecting pipe 1 6 and connecting pipe 2 13 will be tightly pressed against the outer surface of the sealing gasket 14, ultimately achieving a sealed connection. When it is necessary to disassemble connecting pipe 2 5 and connecting pipe 1 4, the rotating ring 11 is rotated in the opposite direction to reconnect sliding groove 2 12 and sliding groove 1 7. At this time, connecting pipe 1 6 and connecting pipe 2 13 can be slid out from the inside of connecting pipe 1 4 and connecting pipe 2 5 respectively, completing the disassembly. Through quick disassembly and assembly, the time spent on pipe connection can be reduced, and the work efficiency can be improved.
[0037] After connecting pipe 6 and connecting pipe 13 are properly connected, connecting pipe 4 can be rotated within a certain range. At this time, the inner ring 2 will rotate inside the outer ring 3 and the fixed shell 1 as connecting pipe 4 rotates. The fixed shell 1 will limit the rotation range of connecting pipe 4. Through the effect of rotation, the limitation of traditional docking devices that can only dock in a straight line is broken, and the practicality of the entire docking device is improved.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
