Description

Technical Field

[0001] This utility model relates to the field of seamless tubes, and specifically to corrosion-resistant copper alloy seamless tubes. Background Technology

[0002] Seamless steel pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter. Steel pipes with hollow cross-sections are widely used as pipelines for transporting fluids, such as oil, natural gas, coal gas, water, and certain solid materials. Copper alloy seamless steel pipe has good corrosion resistance and can resist corrosion and oxidation.

[0003] Seamless steel pipes are generally quite heavy. During the hoisting of copper alloy seamless steel pipes, the hoisting points experience significant stress. Because the interior of a copper alloy seamless steel pipe is hollow, the stress on the hoisting points can cause deformation of the load-bearing sidewalls. Therefore, effectively preventing deformation of the hoisting points of the corrosion-resistant copper alloy seamless steel pipe during hoisting is a crucial design challenge. Utility Model Content

[0004] This invention provides a corrosion-resistant copper alloy seamless tube to better prevent deformation of the lifting points of the corrosion-resistant copper alloy seamless tube body due to excessive stress during the lifting process.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a corrosion-resistant copper alloy seamless tube, including a corrosion-resistant copper alloy seamless tube body, and further comprising:

[0007] A support and adjustment structure is provided inside the corrosion-resistant copper alloy seamless tube body, and the support and adjustment structure supports the inner wall of the corrosion-resistant copper alloy seamless tube body.

[0008] A fixed connection structure is provided at one end of the support and adjustment structure;

[0009] A snap-fit ​​structure is provided at the other end of the support and adjustment structure.

[0010] Preferably, the fixed connection structure includes a fixed block, a sliding rod, a sliding block, a spring, and a sliding cavity. The sliding cavity is formed in the side wall of the fixed block, and the sliding block is slidably connected in the sliding cavity. The spring is fixedly connected between the sliding block and the inner side wall of the sliding cavity. The sliding rod is fixedly connected to the other side of the sliding block and extends out of the fixed block.

[0011] In this technical solution, spring one can easily fix arc block one and arc block two and adjust them elastically according to the size of the corrosion-resistant copper alloy seamless tube body.

[0012] Preferably, the fixed connection structure includes a first fixed arc block, a second fixed arc block, a rotating groove, a threaded groove, and a fixing bolt. The first fixed arc block and the second fixed arc block are respectively fixedly connected to the sliding rod. The first fixed arc block has a rotating groove on its side wall, and the fixing bolt is threadedly connected in the rotating groove. The second fixed arc block has a threaded groove on its side wall, and the fixing bolt and the threaded groove cooperate with each other.

[0013] In this technical solution, the fixing bolts are threaded into the threaded groove and tightened, so that fixing arc block one and fixing arc block two are tightly fixed on the corrosion-resistant copper alloy seamless tube body, thereby fixing the support and adjustment structure inside the corrosion-resistant copper alloy seamless tube body.

[0014] Preferably, the sidewalls of the first and second fixed arc blocks are provided with arc-shaped through grooves.

[0015] Preferably, the support adjustment structure includes a fixed rod, a connecting rod, a first threaded rod, a second threaded rod, a rotating block, a rotating rod, and a support block. The fixed rod is fixedly connected at equal intervals to the side wall of the first fixed block. The other end of the fixed rod is fixedly connected to the support block. The second threaded rod is rotatably connected to the side wall of the support block. The other end of the second threaded rod is fixedly connected to the connecting rod. The other end of the connecting rod is fixedly connected to the first threaded rod. The other end of the first threaded rod is rotatably connected to the side wall of the first fixed block. One end of the rotating rod is fixedly connected to the end of the second threaded rod, and the other end of the rotating rod is fixedly connected to the rotating block.

[0016] In this technical solution, rotating the rotating block causes the second threaded rod to rotate, which in turn causes the connecting rod to rotate, which in turn causes the first threaded rod to rotate. The rotation of the first and second threaded rods causes the two moving blocks to move.

[0017] Preferably, the threads on threaded rod one and threaded rod two are opposite.

[0018] In this technical solution, two moving blocks are driven to move closer to each other or further apart.

[0019] Preferably, the sidewall of the support block is provided with locking grooves at equal intervals.

[0020] Preferably, the support adjustment structure includes a support arc block, a second fixed block, a rotating support rod, a third fixed block, and a movable block. The movable block is threadedly connected to the first and second threaded rods, and the third fixed block is fixedly connected to the sidewalls of the four sides of the movable block. The rotating support rod is rotatably connected to the third fixed blocks. The other end of the rotating support rod is rotatably connected to the second fixed block, and the second fixed block is fixedly connected to the four support arc blocks.

[0021] In this technical solution, the movement of the moving block causes the rotating support rod to rotate, and the rotation of the rotating support rod causes the support arc block to move up and down. This allows for a better adjustment of the size of the support adjustment structure according to the size of the corrosion-resistant copper alloy seamless tube body.

[0022] Preferably, the snap-fit ​​structure includes a sliding groove, a snap-fit ​​rod, a second sliding block, and a second spring. The sliding groove is formed on the side wall of the rotating block, and the second sliding block is fixedly connected to the side wall of the snap-fit ​​rod. The snap-fit ​​rod and the second sliding block are slidably connected in the sliding groove, and the second spring is fixedly connected between the second sliding block and the sliding groove.

[0023] Preferably, the locking rod and the locking groove cooperate with each other.

[0024] In this technical solution, the locking rod is engaged into the corresponding locking groove, and the locking rod restricts the rotating block to prevent the rotating block from rotating and causing the supporting arc block to move.

[0025] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] 1. By rotating the rotating block, the rotating block drives the threaded rod one and the threaded rod two to rotate. The rotation of the threaded rod one and the threaded rod two drives the two moving blocks to move. The movement of the moving blocks drives the rotating support rod to rotate. The rotation of the rotating support rod drives the support arc block to move up and down, which makes it easier to adjust the size of the support adjustment structure according to the size of the corrosion-resistant copper alloy seamless tube body.

[0028] 2. By engaging the snap-fit ​​rod into the corresponding snap-fit ​​groove, the snap-fit ​​rod restricts the rotating block, thus preventing the rotating block from rotating and causing the support arc block to move, which would result in the support adjustment structure not providing sufficient support for the corrosion-resistant copper alloy seamless tube body.

[0029] 3. By connecting the fixing bolts to the threaded grooves and tightening them, fixing arc blocks one and two are firmly fixed to the corrosion-resistant copper alloy seamless tube body. This fixes the support and adjustment structure inside the corrosion-resistant copper alloy seamless tube body. The lifting pad is placed at fixing arc blocks one and two, and the support arc blocks are placed against the inner wall of the corrosion-resistant copper alloy seamless tube body for support. This helps to better prevent the lifting points of the corrosion-resistant copper alloy seamless tube body from deforming due to large forces during the lifting process. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0037] like Figure 1-4 As shown, the corrosion-resistant copper alloy seamless tube includes a corrosion-resistant copper alloy seamless tube body 1, and also includes:

[0038] A support and adjustment structure 4 is provided inside the corrosion-resistant copper alloy seamless tube body 1, and the support and adjustment structure 4 supports the inner wall of the corrosion-resistant copper alloy seamless tube body 1.

[0039] Fixed connection structure 2, which is disposed at one end of the support adjustment structure 4;

[0040] The snap-fit ​​structure 6 is located at the other end of the support and adjustment structure 4.

[0041] The fixed connection structure 2 includes a fixed block 211, a sliding rod 212, a sliding block 213, a spring 214, and a sliding cavity 215. The sliding cavity 215 is formed in the side wall of the fixed block 211. The sliding block 213 is slidably connected in the sliding cavity 215. The spring 214 is fixedly connected between the sliding block 213 and the inner side wall of the sliding cavity 215. The sliding rod 212 is fixedly connected to the other side of the sliding block 213 and extends out of the fixed block 211.

[0042] Spring 1 214 can easily fix arc block 1 201 and arc block 2 202 and adjust them elastically according to the size of the corrosion-resistant copper alloy seamless tube body 1.

[0043] The fixed connection structure 2 includes a first fixed arc block 201, a second fixed arc block 202, a rotating groove 203, a threaded groove 204, and a fixing bolt 205. The first fixed arc block 201 and the second fixed arc block 202 are respectively fixedly connected to the sliding rod 212. The rotating groove 203 is provided on the side wall of the first fixed arc block 201, and the fixing bolt 205 is threadedly connected in the rotating groove 203. The threaded groove 204 is provided on the side wall of the second fixed arc block 202. The fixing bolt 205 and the threaded groove 204 cooperate with each other.

[0044] The fixing bolt 205 is threaded into the threaded groove 204 and tightened, so that the fixing arc block 1 201 and fixing arc block 202 are tightly fixed on the corrosion-resistant copper alloy seamless tube body 1, thereby fixing the support adjustment structure 4 inside the corrosion-resistant copper alloy seamless tube body 1.

[0045] Arc-shaped through grooves 3 are provided on the side walls of the fixed arc block 1 201 and the fixed arc block 2 202.

[0046] The support adjustment structure 4 includes a fixed rod 411, a connecting rod 412, a first threaded rod 413, a second threaded rod 414, a rotating block 415, a rotating rod 416, and a support block 417. The fixed rod 411 is fixedly connected at equal intervals to the side wall of the first fixed block 411. The other end of the fixed rod 411 is fixedly connected to the support block 417. The second threaded rod 414 is rotatably connected to the side wall of the support block 417. The other end of the second threaded rod 414 is fixedly connected to the connecting rod 412. The other end of the connecting rod 412 is fixedly connected to the first threaded rod 413. The other end of the first threaded rod 413 is rotatably connected to the side wall of the first fixed block 411. One end of the rotating rod 416 is fixedly connected to the end of the second threaded rod 414. The other end of the rotating rod 416 is fixedly connected to the rotating block 415.

[0047] Rotate the rotating block 415, which drives the second threaded rod 414 to rotate. The second threaded rod 414 drives the connecting rod 412 to rotate. The connecting rod 412 drives the first threaded rod 413 to rotate. The rotation of the first threaded rod 413 and the second threaded rod 414 drives the two moving blocks 405 to move.

[0048] The threads on threaded rod 413 and threaded rod 414 are opposite.

[0049] This causes the two moving blocks 405 to move closer to each other or further apart.

[0050] The support block 417 has slots 5 at equal intervals on its side wall.

[0051] The support adjustment structure 4 includes a support arc block 401, a second fixed block 402, a rotating support rod 403, a third fixed block 404, and a moving block 405. The moving block 405 is threadedly connected to the first threaded rod 413 and the second threaded rod 414, respectively. The third fixed block 404 is fixedly connected to the side walls of the four sides of the moving block 405. The rotating support rod 403 is rotatably connected to the third fixed block 404. The other end of the rotating support rod 403 is rotatably connected to the second fixed block 402. The second fixed block 402 is fixedly connected to the four support arc blocks 401.

[0052] The movement of the movable block 405 causes the rotating support rod 403 to rotate, and the rotation of the rotating support rod 403 causes the support arc block 401 to move up and down, which can better adjust the size of the support adjustment structure 4 according to the size of the corrosion-resistant copper alloy seamless tube body 1.

[0053] The snap-fit ​​structure 6 includes a sliding groove 601, a snap-fit ​​rod 602, a second sliding block 603, and a second spring 604. The sliding groove 601 is formed on the side wall of the rotating block 415. The second sliding block 603 is fixedly connected to the side wall of the snap-fit ​​rod 602. The snap-fit ​​rod 602 and the second sliding block 603 are slidably connected in the sliding groove 601. The second spring 604 is fixedly connected between the second sliding block 603 and the sliding groove 601.

[0054] The locking rod 602 and the locking groove 5 cooperate with each other.

[0055] The locking rod 602 is engaged into the corresponding locking slot 5. The locking rod 602 restricts the rotating block 415 to prevent the rotating block 415 from rotating and causing the support arc block 401 to move.

[0056] In use, rotating block 415 rotates the threaded rod 414, which in turn rotates the connecting rod 412. The connecting rod 412 then rotates the threaded rod 413. The rotation of threaded rod 413 and threaded rod 414 moves two moving blocks 405. The movement of moving blocks 405 causes the rotating support rod 403 to rotate, which in turn moves the support arc block 401 up and down. This allows for better adjustment of the size of the support adjustment structure 4 according to the size of the corrosion-resistant copper alloy seamless tube body 1.

[0057] After adjustment, snap the snap rod 602 into the corresponding snap groove 5. The snap rod 602 restricts the rotating block 415 to prevent the rotating block 415 from rotating and causing the support arc block 401 to move. Place the adjusted support adjustment structure 4 into the corrosion-resistant copper alloy seamless tube body 1. Fit the first fixed arc block 201 and the second fixed arc block 202 onto the outer wall of the corrosion-resistant copper alloy seamless tube body 1. The spring 214 can easily adjust the first fixed arc block 201 and the second fixed arc block 202 according to the size of the corrosion-resistant copper alloy seamless tube body 1.

[0058] Next, connect the fixing bolt 205 to the threaded groove 204 and tighten it so that the fixing arc block 1 201 and fixing arc block 202 are firmly fixed to the corrosion-resistant copper alloy seamless tube body 1. This fixes the support adjustment structure 4 inside the corrosion-resistant copper alloy seamless tube body 1. When hoisting the corrosion-resistant copper alloy seamless tube body 1, the hoisting pad can be placed at the fixing arc block 1 201 and fixing arc block 202. The support arc block 401 is exactly against the inner wall of the corrosion-resistant copper alloy seamless tube body 1 to support the corrosion-resistant copper alloy seamless tube body 1. This can better prevent the hoisting point of the corrosion-resistant copper alloy seamless tube body 1 from deforming due to large force during the hoisting process.
