Description

Technical Field

[0001] This utility model relates to the field of pipeline connection equipment technology, and more specifically, to an internal support structure for pipeline connection. Background Technology

[0002] In current operations, there are often situations where it is necessary to temporarily connect and connect several pipelines to form a longer pipeline. For example, in the petrochemical industry, when carrying out pipeline maintenance, equipment commissioning, or temporary process changes, it is necessary to temporarily connect different parts of the pipeline.

[0003] Currently, welding is a common technique for temporary pipe connections. Specifically, operators first clean the ends of the two pipes to be connected, removing surface oil, rust, and other impurities to ensure weld quality. Then, using specialized welding equipment, high temperatures are used to melt the welding rod or wire, firmly connecting the ends of the two pipes together. However, this welding method has significant drawbacks.

[0004] When temporary pipe connections need to be cut off later, the cutting process can easily damage the pipe itself. The high temperatures and mechanical stress generated during cutting can alter the metal structure of the pipe ends, potentially leading to cracks, deformation, and other problems. This can affect the pipe's subsequent normal use, and in severe cases, even render the entire pipe section unusable. Furthermore, welding is an extremely time-consuming and labor-intensive process. From the initial pretreatment of the pipe ends to the precise adjustment of welding parameters during welding, and finally to the quality inspection of the weld after completion, each step requires a significant investment of time and effort from the operators. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose an internal support structure for pipe connections.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An internal support structure for pipe connection includes a mounting plate with multiple sets of telescopic parts arranged circumferentially on the mounting plate. Each telescopic part is connected to a support plate at its telescopic end. A rotating shaft is also rotatably connected to the mounting plate. One end of the rotating shaft is connected to a guide part that connects to the telescopic part, and the other end of the rotating shaft is connected to a drive part. When the drive part operates, it can rotate the guide part, causing the telescopic part to drive the support plate to extend outward or retract inward.

[0008] In the above scheme, there are 4-6 sets of telescopic parts.

[0009] In the above solution, the telescopic part includes a slide groove, which is located on the surface of the mounting plate, and a slide bar connected to the support plate is slidably fitted inside the slide groove. The slide bar is provided with a tracking shaft connected to the guide part.

[0010] In the above scheme, the guide part includes a turntable, which is connected to a rotating shaft, and the turntable is provided with a guide groove on its circumference for connecting the tracking shaft. The guide groove is arc-shaped.

[0011] In the above scheme, the driving unit is a drive motor, which is mounted on the mounting plate and connected to the rotating shaft.

[0012] In the above scheme, the drive unit includes a gear one, which is mounted on a rotating shaft and meshes with a gear two. The gear two is connected to a mounting shaft, which is rotatably mounted on a mounting plate and connected to a crank handle.

[0013] In the above scheme, a rubber plate is provided on the outer side of the support plate.

[0014] In the above scheme, the support plate has an arc-shaped structure.

[0015] In the above scheme, the end plates of each support plate come into contact to form a complete circular body.

[0016] The above solution also includes a handheld part, which is detachably connected to the circular body.

[0017] In the above scheme, the outer side of the circular body is provided with external threads, the hand-held part includes a fixed cover, the inner diameter of the fixed cover matches the outer diameter of the circular body, and the inner wall of the fixed cover is provided with internal threads that mate with the external threads, and a handle is installed on the fixed cover.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In this utility model, the multiple sets of telescopic parts arranged around the circumference of the mounting plate, and the support plate connected to each set of telescopic parts, can form a uniform support force on the inner wall of the pipe after extending outward, so as to firmly connect the two pipes together and ensure the reliability of the connection.

[0020] 2. Compared with traditional welding methods, this utility model does not generate high temperature and mechanical stress during connection and disassembly, and does not cause changes in the metal structure of the pipe port, thus avoiding problems such as port cracks and deformation, effectively protecting the pipe, not affecting the normal use of the pipe in the future, and preventing the pipe from being scrapped.

[0021] 3. Unlike welding operations, this utility model eliminates the need for cumbersome pipe port pretreatment, fine adjustment of welding parameters, and weld quality inspection, greatly saving operators' time and energy, and making the operation simpler and faster.

[0022] 4. This utility model controls the rotation of the shaft through the drive unit, so that the telescopic part drives the support plate to extend outward or retract inward, which can adapt to pipes with different inner diameters and can temporarily connect pipes of different specifications, meeting the temporary connection needs of various pipes of different specifications, and has strong versatility and adaptability.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0031] An internal support structure for pipe connections, see attached figure. Figure 1 -Appendix Figure 5As shown, the device includes a circular mounting plate 1 with 4-6 sets of telescopic parts 2 arranged around its circumference. Each telescopic part 2 has an arc-shaped support plate 3 connected to its telescopic end for contacting the inner wall of the pipe. The support plates 3 form a complete circle when their ends come into contact. A rotating shaft 4 is rotatably connected to the center of the mounting plate 1. One end of the rotating shaft 4 is connected to a guide part 5 that connects to the telescopic part 2, and the other end of the rotating shaft 4 is connected to a drive part 6. When the drive part 6 operates, it can rotate the guide part 5, causing the telescopic part 2 to drive the support plate 3 to extend outward or retract inward.

[0032] In the specific implementation of this utility model, please refer to the appendix. Figure 5 As shown, the device is placed at a certain length at the connection port of two pipes. In use, the drive unit 6 drives the rotating shaft 4 to rotate, and the guide part 5 connected to one end of the rotating shaft 4 rotates accordingly. Since the guide part 5 is connected to the telescopic part 2, the rotation of the guide part 5 is converted into the telescopic movement of the telescopic part 2. Subsequently, the telescopic part 2 drives the support plate 3 to extend outward until the support plate 3 contacts the inner wall of the pipe, forming a uniform support force on the inner wall of the pipe. By controlling the rotation of the rotating shaft 4 through the drive unit 6, the telescopic part 2 drives the support plate 3 to extend outward or retract inward, which can adapt to pipes with different inner diameters and meet the temporary connection needs of various pipe specifications.

[0033] For the above scheme, please refer to the appendix. Figure 1 As shown, the telescopic part 2 includes a slide groove 21, which is located on the surface of the mounting plate 1. A slide bar 22 connected to the support plate 3 is slidably fitted inside the slide groove 21. The slide bar 22 is provided with a tracking shaft 23 that connects to the guide part 5. In this design, the slide groove 21 provides guidance for the slide bar 22, allowing the slide bar 22 to move linearly only along the direction of the slide groove 21. When the guide part 5 rotates, the tracking shaft 23 will move, and then the tracking shaft 23 will push or pull the slide bar 22 to slide within the slide groove 21, thereby driving the support plate 3 to telescopically move.

[0034] For the above scheme, please refer to the appendix. Figure 1 As shown, the guide section 5 includes a turntable 51, which is connected to the rotating shaft 4. A guide groove 52 for connecting the tracking shaft 23 is provided on the circumference of the turntable 51, and the guide groove 52 is arc-shaped. In this design, when the rotating shaft 4 rotates, the turntable 51 rotates along with it. When the turntable 51 rotates, the tracking shaft 23 moves under the guidance of the guide groove 52. When the tracking shaft 23 moves within the arc-shaped guide groove 52, it generates a component force along the direction of the slide groove 21. This component force pushes the slide bar 22 to slide linearly within the slide groove 21, thereby causing the support plate 3 to extend outward or retract inward, thus meeting the functional requirements of the pipe internal support structure.

[0035] In one embodiment of the above scheme, refer to the appendix. Figure 3As shown, the drive unit 6 is a drive motor, which is mounted on the mounting plate 1 and connected to the rotating shaft 4. In this design, the drive motor is directly connected to the rotating shaft 4, directly transmitting the rotational motion of the drive motor to the rotating shaft 4. Under the drive of the drive motor, the rotating shaft 4 can rotate synchronously according to the rotational speed and direction of the drive motor, providing accurate power input for the subsequent movement of the guide unit 5 and the telescopic unit 2.

[0036] In another embodiment of the above scheme, refer to the appendix. Figure 4 As shown, the drive unit 6 includes a first gear 61, which is mounted on the rotating shaft 4 and meshes with a second gear 62. The second gear 62 is connected to a mounting shaft 63, which is rotatably mounted on the mounting plate 1 and connected to a crank handle 64. In this design, by cranking the crank handle 64, the mounting shaft 63 can be rotated, which in turn drives the second gear 62 connected to it to rotate. The rotation of the second gear 62 drives the first gear 61 to rotate, thereby effectively transmitting power to the rotating shaft 4.

[0037] In the above scheme, considering the contact effect between the support plate 3 and the inner wall of the pipe, therefore, refer to the appendix. Figure 1 As shown, a rubber plate 31 is provided on the outer side of the support plate 3. In this design, the rubber plate 31 can effectively increase the friction between the support plate 3 and the inner wall of the pipe, so that the support plate 3 can be more stably supported on the inner wall of the pipe, preventing relative sliding between the support plate 3 and the inner wall of the pipe, thereby ensuring the stability of the inner support structure for the pipe connection; at the same time, when the support plate 3 contacts the inner wall of the pipe, it can play a buffering role, avoiding the support plate 3 directly contacting the inner wall of the pipe rigidly and scratching or damaging the inner wall of the pipe.

[0038] For the above solutions, considering the ease of equipment relocation, please refer to the appendix. Figure 6 As shown, it also includes a handle 7, which is detachably connected to the circular body. Specifically, the outer side of the circular body is provided with an external thread 32. The handle 7 includes a fixing cover 71, the inner diameter of which matches the outer diameter of the circular body, and the inner wall of the fixing cover 71 is provided with an internal thread 72 that mates with the external thread 32. A handle 73 is installed on the fixing cover 71. In this design, when the equipment needs to be moved, the handle 7 can be screwed onto the circular body. After the equipment is moved, the handle 7 can be easily detached without affecting the use of other functions of the equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
