Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline connection technical field especially a kind of welding-free pipeline riveting structure. BACKGROUND

[0002] In the existing pipeline connection technology, riveting technology as an important non-welding connection method has been widely used in many fields, especially in occasions that need frequent disassembly and assembly. These occasions include but are not limited to oil fields, natural gas pipelines and industrial water treatment facilities. In these environments, due to the need for periodic inspection of equipment, maintenance or replacement of parts, the connection part must be easily disassembled and reassembled. Riveting technology meets this demand, as it does not require welding, thereby avoiding problems such as thermal deformation and residual stress that may be caused by welding, and also greatly simplifying the disassembly and reassembly process.

[0003] However, although traditional riveting technology has shown its practicality and convenience in these application occasions, it also has a significant limitation: the tightness is fixed, and once riveting is completed, it cannot be flexibly adjusted according to actual working conditions or maintenance needs. This fixed tightness design may not guarantee the best connection effect when facing complex and variable working conditions. For example, in environments with large temperature changes, the thermal expansion and contraction of materials may cause the connection to loosen or be overly tight, thereby affecting the stability and efficiency of the pipeline connection. In addition, fixed tightness also increases the complexity of maintenance and repair, as maintenance personnel may need to make additional adjustments or reinforcements to the connection part under different environmental conditions to ensure its stability and safety. SUMMARY

[0004] The problem to be solved by the utility model is to provide a welding-free pipeline riveting structure that can flexibly adjust the tightness to adapt to different working conditions and maintenance needs, thereby improving the stability and efficiency of the pipeline connection and simplifying the maintenance and repair process.

[0005] To solve the above technical problems, the utility model adopts the technical scheme of a welding-free pipeline riveting structure, which includes a first connecting pipe and a tightness adjusting mechanism. The left end of the first connecting pipe is in contact with a second connecting pipe. A second hollow circular block is fixedly connected inside the first connecting pipe. A first hollow circular block is fixedly connected inside the second connecting pipe.

[0006] The tightness adjusting mechanism includes a hollow sleeve. A threaded groove is formed in the inside of the hollow sleeve. A threaded ring block is threadedly connected to the inner wall of the threaded groove. A hollow pipe is fixedly connected to the threaded ring block.

[0011] Preferably, the welding-free pipeline riveting structure, wherein the side of the second hollow circular block close to the second connecting pipe is in contact with the first hollow circular block, and the material of the second hollow circular block and the first hollow circular block is carbon fiber.

[0023] Adjusting mechanism 3 includes hollow sleeve 301, threaded groove 302 is set in the inside of hollow sleeve 301, threaded ring block 303 is connected in screw thread on the inner wall of threaded groove 302, threaded ring block 303 is fixedly connected with hollow pipe 304.

[0024] Hollow sleeve 301 is fixedly connected on second hollow round block 7, hollow pipe 304 is slidably connected with the inside of hollow sleeve 301.

[0025] Hollow pipe 304 is fixedly connected with hollow screw block 305 at the end away from threaded ring block 303, hollow screw block 305 is rotatably connected with hollow backing plate 306 on the side away from hollow pipe 304.

[0026] Limiting groove 4 is set in the inside of second connecting pipe 2, limiting bead 5 is fixedly connected on the side of first connecting pipe 1 close to second connecting pipe 2.

[0027] The limiting bead 5 contacts the inside of the limiting groove 4 to position the first connecting pipe 1 and the second connecting pipe 2.

[0028] The side of the second hollow block 7 closest to the second connecting pipe 2 is in contact with the first hollow block 6. Both the second hollow block 7 and the first hollow block 6 are made of carbon fiber.

[0029] There are four limiting grooves 4, all located on one side of the connection between the second connecting pipe 2 and the first connecting pipe 1. There are four first hollow round blocks 6, all located inside the connection between the second connecting pipe 2 and the first connecting pipe 1.

[0030] There are four second hollow round blocks 7, all located inside the connection between the first connecting pipe 1 and the second connecting pipe 2, with the same position as the first hollow round block 6. There are four limiting beads 5, all located on the side of the first connecting pipe 1 near the second connecting pipe 2, with the same position as the limiting groove 4.

[0031] There are four tightening mechanisms 3, and each second hollow block 7 has one tightening mechanism 3 on the side away from the first hollow block 6. Example 1

[0032] like Figures 1 to 4 As shown, in practical applications, the first connecting pipe 1 and the second connecting pipe 2 are initially positioned and connected by the limiting bead 5 and the limiting groove 4. The tightening mechanism 3 adjusts the tightness between the two connecting pipes by rotating the hollow tightening block 305, thereby meeting different working conditions and maintenance needs. Specifically, when it is necessary to increase the tightness, simply rotate the hollow tightening block 305 with a wrench, causing it to move the threaded ring block 303 outward along the threaded groove 302, thus tightening the two connecting pipes. Conversely, when it is necessary to decrease the tightness, simply rotate the hollow tightening block 305 in the opposite direction. This design not only improves the stability and efficiency of the pipe connection but also greatly simplifies the maintenance and repair process. Example 2

[0033] like Figures 1 to 3 As shown, in practical applications, the second hollow circular block 7 and the first hollow circular block 6 are made of carbon fiber. This material not only has high strength and rigidity but is also lightweight and corrosion-resistant, effectively improving the performance and service life of the entire connection structure. During assembly, the mutual cooperation of the limiting bead 5 and the limiting groove 4 allows the first connecting pipe 1 and the second connecting pipe 2 to be quickly positioned correctly. This design not only simplifies the assembly steps but also improves the accuracy and efficiency of assembly. Simultaneously, during pipe use, the limiting bead 5 and the limiting groove 4 also prevent relative movement of the two connecting pipes, thereby enhancing the stability of the pipe connection.

Then, the rivet is extruded through the rivet tool, so that the first connecting pipe 1 and the second connecting pipe 2 are riveted. When the riveting is completed, the two connecting pipes are tightened by the tightening mechanism 3. Specifically, the hollow block 305 is rotated by an external wrench, the hollow block 305 drives the hollow gasket 306, the hollow pipe 304 and the threaded ring block 303 to move outward along the threaded groove 302, so that a tight force in the direction of the first connecting pipe 1 is applied to the second connecting pipe 2. By adjusting the moving distance of the threaded ring block 303, the size of the tight force can be accurately controlled, so as to meet different working conditions and maintenance requirements. In addition, the second hollow circular block 7 and the first hollow circular block 6 are made of carbon fiber material, which has high strength and rigidity, light weight, good corrosion resistance, and further improves the performance and service life of the whole connecting structure.
