Description

Technical Field

[0001] The present invention relates to the technical field of pipeline detection devices, and particularly to a detection device and method for water conservancy project pipelines. Background Art

[0002] In water conservancy project construction, metal structures and pipelines are often built underwater to meet the requirements of water conservancy project construction. The pipelines underground will be subjected to various reverse external pressures and internal water pressure internal tensions, resulting in damage to the pipeline during use.

[0003] Therefore, during the pipeline production process, it is necessary to conduct strength detection on the pipelines so that the pipelines can meet the subsequent water conservancy project usage. The existing detection methods are to simply conduct strength detection on the pipelines by stretching and squeezing them with a tensile machine, or to conduct extrusion strength detection on the side of the pipeline with a pressing block, etc. This makes the detection of the pipelines too single, unable to effectively simulate various strength forces that the pipelines are subjected to during use. Moreover, there are types such as straight pipelines and corrugated pipelines for water conservancy pipelines, and different detection methods are required according to different types, which makes it necessary to use multiple sets of detection machines for detection, increasing the production and manufacturing costs. Therefore, a detection device and method for water conservancy project pipelines are proposed. Summary of the Invention

On the side surface of the toothed rod, a damping block for clamping and limiting is arranged. On the other side of the toothed rod, a clamping block and a matching block are arranged, and a first detection block and a second detection block are respectively arranged inside them.

[0010] Furthermore, a connecting rod is fixedly installed on the side surface of the friction block, the second gear is splined and sleeved on the side surface of the connecting rod, a first support cylinder is fixedly connected between the side surfaces of the second gear and the friction block, and a synchronous belt is meshed and sleeved on the side surface of the second gear.

[0011] Furthermore, the connecting frame is fixedly installed on the side surface of the gear ring, slots are equidistantly opened on the side surface of the connecting frame, the tooth bar is movably installed inside the slots, a restraint block is fixedly installed on the wall surface of the slots, the damping block is clamped on the side surface of the tooth bar, a restraint rod is fixedly installed on the outer side of the connecting frame and the restraint rod penetrates through the damping block, and a return spring is fixedly connected between the side surfaces of the damping block and the restraint rod.

[0012] Furthermore, a mounting block is arranged on the side surface of the tooth bar, a clamping block is fixedly installed on the side surface of the mounting block, a movable cavity is opened on the concave side surface of the clamping block, a movable rod is movably installed inside the movable cavity, a second support cylinder is fixedly connected between the side surface of the movable rod and the wall surface of the movable cavity, a matching block is fixedly installed on the side surface of the movable rod away from the second support cylinder and the matching block is slightly higher than the side surface of the clamping block, a first detection block is arranged on the wall surface of part of the movable cavity, and a second detection block is threadedly installed inside part of the matching block and the clamping block.

[0013] Furthermore, the auxiliary rod is arranged on the upper side of the workbench, an opening is opened on the side surface of the auxiliary rod, the telescopic rod is fixedly installed on the upper side of the workbench, and the support plate is clamped at the side surface of the output end of the telescopic rod.

[0014] A use method of a detection device for a water conservancy project pipeline includes the following steps: Before detection: First step, select a corresponding detection method for subsequent detection according to different pipelines and fix and install it.

[0015] Second step, when clamping the outside, the electric slide table drives the sliding carriage to move the two driving components to the position between the support plates, place the pipeline on the upper side of the support plates and insert it into the inner side of the mounting bracket, manually adjust the telescopic rod to make the support plates support the pipeline to a general height position, and wait for detection.

[0016] In the third step, when clamping the inner side, the electric slide table drives the carriage to move the two sets of driving components to the outer positions of the two sets of support plates. Before moving, remove the support plates to avoid interference. First, remove the mounting block on the side of the rack bar and install it on the side of the auxiliary rod through bolts. Then, install one side of the auxiliary rod on the side position of the rack bar through bolts. Similarly, place the pipeline on the upper side of the support plate, adjust the position, and sleeve the pipeline on the side of the auxiliary rod. Then, install the other end of the auxiliary rod on the side of the rack bar inside the other set of clamping components through bolts, and wait for inspection.

[0017] Further, the following steps are also included: During inspection: In the first step, select the corresponding inspection program according to the inspection requirements to perform the inspection operation on the pipeline.

[0018] In the second step, first, the electric push rod pushes the friction block away from the side of the first gear, so that the second gear can be engaged with the rack bar. Similarly, the damping block moves away from the side of the rack bar to unlock it. When the motor drives the electric push rod to rotate, it can drive the second gear to engage with the rack bar. At this time, the first gear is not driven, and the rack bar drives the clamp block and the mating block to cooperate to clamp the inner or outer side of different pipelines. After the pipeline is clamped, the rack bar can be continuously driven to make the clamp block and the mating block generate extrusion strength detection on the inner or outer side of different pipelines.

[0019] In the third step, after clamping the pipeline, the electric slide table can be used to drive the carriage to drive the mounting frame to move closer or farther away to perform compression and tearing strength detection on the pipeline; or the electric push rod pulls the friction block to insert into the first gear and engage with it for limiting, the second gear disengages from the side of the rack bar and does not engage with it, and the damping block resets to generate frictional limit fixation on the rack bar. At this time, the motor drives the electric push rod to drive the first gear to engage with the gear ring to make the gear ring rotate. The gear ring drives the entire connecting frame to rotate. When the connecting frames inside the two sets of driving components rotate in the same direction, the pipeline can be driven to rotate to directly observe whether there is damage on the side. When the connecting frames inside the two sets of driving components rotate in different directions, the pipeline can be subjected to torsional strength testing.

[0020] Further, the following steps are also included: After inspection: In the first step, when clamping the outer side of the pipeline, the clamp block and the mating block inside one set of driving components continue to clamp the pipeline, and the clamp block and the mating block inside the other set of driving components are driven to slightly move away from the outer side of the pipeline. Then, drive the connecting frame to rotate and cooperate with the carriage to drive the mounting frame to move, so as to perform battery ultrasonic flaw detection on the side of the pipeline through the second detection block. Similarly, reverse operation can complete the flaw detection operation after the pipeline strength detection to assist the staff in judging the pipeline strength.

[0021] In the second step, when clamping the inner side of the pipeline, first remove the pipeline, and then change to clamping the outer side, so as to perform the flaw detection operation to assist the staff in judging the pipeline strength as above.

[0022] In the third step, after flaw detection, disassemble the pipeline for subsequent other inspections and measurements. Reset each component of the machine, and then cut off the power supply after inspection, maintenance, and servicing.

[0023] Compared with the prior art, the beneficial effects that the present invention can achieve are as follows:

[0024] 1. By setting up an electric slide table, a driving component, and a clamping component, the present invention can perform multi-state inspections on pipelines. It can simulate the strength inspections of pipelines under various conditions such as external and internal pressure, lateral torsion force, tensile and extrusion forces, etc. Moreover, it can adapt to different pipeline types and stably clamp them to ensure the stability during pipeline inspection.

[0025] 2. By setting up a driving component, the present invention can achieve multi-state driving of each component of the clamping component, and its internal structure is mechanically linked, which can stably ensure that each component will not be damaged or displaced when applying force during testing.

[0026] 3. By setting up components such as a gear ring, a first gear, and a synchronous belt, the present invention can achieve synchronous driving of each component by a single driving motor, ensuring the stability of driving and the concentric constraint clamping for subsequent pipeline inspection, and reducing the energy consumption of equipment use.

[0027] 4. By setting up a clamping component, the present invention can cooperate with the driving component to perform inspection operations on pipelines. Moreover, the clamping blocks and the cooperating blocks can adapt to different pipelines for clamping, ensuring the stability of clamping. After clamping, they can cooperate with the driving component to drive the pipeline to rotate in the same and different directions, improving the versatility of the clamping component.

[0028] 5. By setting up a damping block and its surrounding components, when the rack is not driven, the damping block can be clamped on its side for frictional limiting, ensuring the stability of the rack's pause. When the rack is driven, the damping block can be squeezed to disengage from the side of the rack, avoiding interference with the movement of the rack.

[0029] 6. By setting up a first detection block, a second detection block, and their surrounding components, the first detection block can determine whether the clamping blocks and the cooperating blocks are level when clamping a straight pipe by detecting the distance of the detection moving rod, and can determine the major diameter of the auxiliary calculator when detecting a corrugated pipe, assisting personnel in detecting pipeline data; the second detection block can cooperate with other components to perform electromagnetic ultrasonic flaw detection on the pipeline by rotating and fitting on the side of the pipeline, assisting the staff in judging the strength of the pipeline.

[0030] 7. By setting up an auxiliary component, the present invention can cooperate with other components to clamp the inner side of the pipeline and detect the inner side force strength. Moreover, the provided support plate can provide auxiliary support for the pipeline, facilitating its stability when not clamped, eliminating the need to manually maintain the height position of the pipeline, ensuring that personnel can stay away from the machine during inspection, and guaranteeing the safety of personnel operation.

Detailed implementation manners

[0042] In order to make the technical means, creative features, achieved purposes and functions realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments can be obtained from commercial channels unless otherwise specified.

[0043] Embodiment: As Figure 1 and Figure 2 shown, a detection device for a water conservancy project pipeline includes a workbench 1. The workbench 1 is a rectangular table. Two sets of electric slides 2 are symmetrically and staggeredly arranged on the upper side of the workbench 1. Slide frames 21 are fixedly installed on the slide sides of the two sets of electric slides 2 respectively, and the slide frames 21 are sleeved on the side of the other set of electric slides 2. A drive assembly 3 capable of multi-state driving is symmetrically arranged on the upper side of the slide frame 21. An inner clamping assembly 4 capable of multi-state clamping of the pipeline is arranged inside the drive assembly 3. An auxiliary assembly 5 for assisting in detection is arranged on the upper side of the workbench 1;

[0044] The drive assembly 3 provided can perform multi-state driving on other components and can ensure the stability of the driving;

[0045] As Figures 4 to 7As shown, the drive assembly 3 includes a mounting frame 31 arranged on the upper side of the slide 21, and the mounting frame 31 is fixed to the upper side position of the slide 21 through a connecting piece, the mounting frame 31 is a circular ring frame, and a mounting cavity 311 is opened on the inner side of the mounting frame 31, and the mounting cavity 311 is a circular cavity with a convex cross-section, a gear ring 32 is movably arranged inside the mounting cavity 311, and the gear ring 32 is attached to the wall surface of the mounting cavity 311, the gear ring 32 is a circular plate with a toothed outer side, three groups of first gears 33 are equidistantly arranged in a circular array on the side surface of the gear ring 32, and the three groups of first gears 33 are arranged inside the mounting cavity 311, the first gear 33 is a circular gear with a convex cylindrical groove on the side surface, an electric push rod 34 is movably installed inside the first gear 33, and the electric push rod 34 extends through the mounting frame 31, and a friction block 35 is fixedly connected to the output end of the electric push rod 34, and the friction block 35 is clamped on the inner side of the first gear 33, and the friction block 35 is a pressure-sensitive resistant The convex-shaped round block is ground, and a motor 36 is provided on the side of one group of electric push rods 34 away from the friction block 35, and the motor 36 is fixedly connected to the side of the electric push rod 34 through a connecting member coupling. In addition, the motor 36 is fixedly mounted on the side of the mounting frame 31 through a rectangular plate, and an auxiliary plate 37 is rotatably mounted on the side of the other two groups of electric push rods 34 away from the friction block 35, and the auxiliary plate 37 is fixedly mounted on the side position of the mounting frame 31, and the auxiliary plate 37 is a cross-shaped plate; specifically, the motor 36 can drive the electric push rod 34 to rotate, and when the friction block 35 is clamped in the first gear 33, the first gear 33 rotates with the electric push rod 34 and meshes with the gear ring 32, and as the gear ring 32 rotates, the remaining first gears 33 mesh with it and rotate themselves under the constraint of the electric push rod 34, completing the synchronous rotation of the three groups of first gears 33. In addition, the electric push rod 34 is set to push the friction block 35 to slide out of the first gear 33, so that the motor 36 does not drive the first gear 33;

[0046] A connecting rod 351 is fixedly installed on the side of the friction block 35 away from the electric push rod 34. The connecting rod 351 is a convex-shaped round rod with splines on the side. A second gear 352 is movably sleeved on the side of the connecting rod 351, and the second gear 352 is sleeved with the connecting rod 351 in a spline manner. The rotation on the side is limited. The second gear 352 is a circular gear with a limiting ring on the side. A first support cylinder 353 is fixedly connected between the side of the second gear 352 and the side of the friction block 35, and the first support cylinder 353 is movably sleeved on the side of the connecting rod 351. The first support cylinder 353 is a spring steel cylinder with a cross-section in a continuous "W" shape. A synchronous belt 354 is meshed and sleeved on the side of the second gear 352. The synchronous belt 354 is a rubber "O" belt with teeth on the inner side. Specifically, when the electric push rod 34 pushes the friction block 35 out of the inside of the first gear 33, the connecting rod 351 can move accordingly. The first support cylinder 353 elastically supports the second gear 352, so that the second gear 352 can be elastically clamped and engaged with other components later. Whether the second gear 352 is clamped in place can be judged by the force received on the side of the friction block 35. When the friction block 35 rotates, the second gear 352 can be driven to rotate and engage with the later components through the connecting rod 351. In addition, the provided synchronous belt 354 can synchronize all the second gears 352, so that a set of driving ends can drive each component to move synchronously, which is convenient for concentric clamping and restraint when clamping the pipeline.

[0047] The provided clamping assembly 4 can be driven by the driving assembly 3 in different states, so that it can stably clamp a variety of pipelines and perform multi-state detection operations.

[0048] Such as Figures 4 to 6 And Figures 8 to 10As shown, the clamping assembly 4 includes a connecting frame 41 fixedly installed on the side of the gear ring 32, and the connecting frame 41 fits against the wall surface of the installation cavity 311. The connecting frame 41 is a circular ring frame. At the side of the connecting frame 41 corresponding to the notch of the mounting frame 31 and the side of the second gear 352, through slots 411 penetrating it are equidistantly arranged in a circumferential array. The slots 411 are rectangular slots. A toothed rod 42 is movably installed inside the slots 411, and the toothed rod 42 extends out from inside the installation cavity 311. The toothed rod 42 is a rectangular rod with teeth on its side in the shape of a double-square. On the wall surface of the slots 411, a restraint block 421 is fixedly installed, and the restraint block 421 is movably arranged at the inner side position of the toothed rod 42. The restraint block 421 is a rectangular block. A damping block 43 is clamped on the side of the toothed rod 42, and the damping block 43 is arranged outside the connecting frame 41 corresponding to the connecting rod 351. The damping block 43 is an "F"-shaped folding block made of elastic rubber. At the position corresponding to the damping block 43 on the outside of the connecting frame 41, restraint rods 431 are equidistantly fixedly installed, and the restraint rods 431 penetrate the damping block 43. The restraint rods 431 are "T"-shaped cylindrical rods. A return spring 432 is fixedly connected between the side of the damping block 43 and the side of the restraint rod 431, and the return spring 432 is movably sleeved on the side of the restraint rod 431; specifically, when the friction block 35 is pushed, the second gear 352 is elastically supported and elastically obliquely inserted into meshing with the side of the toothed rod 42. Synchronously, the connecting frame 41 can drive the gear ring 32 to rotate slightly. At this time, the first gear 33 is not restricted by driving. The second gear 352 meshes with the toothed rod 42 and drives it to reciprocate under the limit constraint of the restraint block 421. Before the toothed rod 42 meshes with the second gear 352, the connecting rod 351 pushes and presses against the side of the damping block 43, causing the damping block 43 to be constrained by the restraint rod 431 and squeezing the return spring 432 to deform, so that the damping block 43 disengages from the side of the toothed rod 42, and the toothed rod 42 can mesh and move with the second gear 352 without interference. When the friction block 35 is pulled back and inserted into the first gear 33, the damping block 43 is elastically supported by the elastic force of the return spring 432 and reset to be clamped on the side of the toothed rod 42, providing frictional limitation to it and keeping the clamping stable;

[0049] A mounting block 44 is provided on the side of the rack bar 42, and the mounting block 44 is fixedly installed on the side of the rack bar 42 by bolts. The mounting block 44 is a "π"-shaped block. A clamping block 45 is fixedly installed on the side of the mounting block 44 away from the rack bar 42. The clamping block 45 is a comb-shaped block with an arc on one side. A movable cavity 46 is equidistantly opened on the concave side of the clamping block 45. The movable cavity 46 is a cylindrical cavity with a convex cross-section. A movable rod 461 is movably installed inside the movable cavity 46, and the movable rod 461 extends out of the inside of the movable cavity 46. The movable rod 461 is a cylindrical rod with a cross-section in the shape of a cross. A second support cylinder 462 is fixedly connected between the side of the movable rod 461 and the wall surface of the movable cavity 46. The second support cylinder 462 is a cylindrical spring steel cylinder with a cross-section in the shape of a continuous "W". A matching block 463 is fixedly installed on the side of the movable rod 461 away from the second support cylinder 462, and the matching block 463 is slightly higher than the side of the clamping block 45. The matching block 463 is a rectangular block with an arc on one side. A first detection block 464 is provided on the wall surface of a part of the movable cavity 46 corresponding to the position of the second support cylinder 462. The first detection block 464 is a distance sensor (not elaborated in this technical solution, and a model that can detect medium and small distances is sufficient). A second detection block 465 is provided on the sides of a part of the matching block 463 and the clamping block 45. The second detection block 465 is a convex-shaped cylinder integrated with an electromagnetic ultrasonic sensor (this type of sensor is more convenient for flaw detection coupling agent and grinding), a battery block, and a remote information transmitter. The second detection block 465 can be threadedly installed inside the matching block 463 and the clamping block 45; specifically, the clamping block 45 can be fixedly installed on the side of the rack bar 42 through the mounting block 44, and the rack bar 42 drives the clamping block 45 to clamp the pipeline. When it is a straight pipe, the clamping block 45 directly clamps on its side, and the matching block 463 is synchronously pressed and slides into the inner side of the clamping block 45 to be flush with it. When it is a corrugated pipe, the convex part of the corrugated pipe can continue to press the matching block 463 to make it continue to slide into the inner side of the clamping block 45, so that the clamping block 45 and the matching block 463 can cooperate to clamp the corrugated pipe, ensuring stable clamping of different pipelines. Among them, the distance of the movable rod 461 is detected by the first detection block 464. When it is a straight pipe, it can be detected and determined that the clamping block 45 is flush with the matching block 463. When it is a corrugated pipe, the major diameter of the corrugated pipe can be obtained by detecting the distance of the movable rod 461 by the first detection block 464, and its minor diameter can be calculated therefrom, avoiding the difficulty of detecting the outer diameter of the corrugated pipe. In addition, the electromagnetic ultrasonic flaw detection operation can be performed on the straight pipe and the corrugated pipe through the second detection block 465 in the same way as above;

[0050] The auxiliary component 5 provided can assist in detecting the pipeline, and can expand the detection method of the pipeline, improving the detection diversification;

[0051] Such as Figures 1 to 3As shown in the figure, the auxiliary component 5 includes auxiliary rods 51 that are equidistantly arranged on the upper side of the workbench 1. The auxiliary rods 51 are rectangular rods with a comb-like shape on the side. Through holes 511 that penetrate through them are provided on the side of the auxiliary rods 51. The through holes 511 are round holes. On the upper side of the workbench 1, telescopic rods 52 are symmetrically and equidistantly vertically fixedly installed at positions corresponding to the side of the electric sliding table 2. The telescopic rods 52 are round rods that can be manually telescopically adjusted, and can also be replaced with electric push rods 34. A support plate 53 is arranged on the upper side of the telescopic rods 52, and the support plate 53 is clamped at the side position of the output end of the telescopic rods 52. The support plate 53 is an arc-shaped plate; specifically, the height position of the support plate 53 can be adjusted through the telescopic rods 52, so that the telescopic rods 52 can provide support assistance before pipeline detection, facilitating the installation and detection of the pipeline, and the support plate 53 is detachable to avoid interference caused by the sliding frame 21 driving the driving component 3 to move. By means of the provided auxiliary rods 51, they can be installed on the side of the rack 42 with bolts, so that the rack 42 can drive the auxiliary rods 51 to move. The mounting block 44 is installed at any position on the side of the auxiliary rod 51 with bolts, and the auxiliary rod 51 with the clamping block 45 is arranged inside the pipeline. In this way, the rack 42 can drive the clamping block 45 and its surrounding components to squeeze and clamp the inside of the pipeline, so as to squeeze the inside of the pipeline and drive it to rotate.

[0052] A method for using a detection device for a water conservancy project pipeline:

[0053] Before detection: First step, select the corresponding detection method according to different pipelines for subsequent detection and fix and install it.

[0054] Second step, when clamping the outside, the electric sliding table 2 drives the sliding frame 21 to move the two driving components 3 to the position between the support plates 53. Place the pipeline on the upper side of the support plates 53 and insert it into the inside of the mounting frame 31. Manually adjust the telescopic rods 52 to make the support plates 53 support the pipeline to a general height position and wait for detection.

[0055] Third step, when clamping the inside, the electric sliding table 2 drives the sliding frame 21 to move the two driving components 3 to positions outside the two support plates 53. Remove the support plates 53 before moving to avoid interference. First, disassemble the mounting block 44 on the side of the rack 42 and install it on the side of the auxiliary rod 51 with bolts, and then install one side of the auxiliary rod 51 on the side of the rack 42 with bolts. Similarly, place the pipeline on the upper side of the support plates 53, adjust the position, and when the pipeline is sleeved on the side of the auxiliary rod 51, install the other end of the auxiliary rod 51 on the side of the rack 42 inside the other clamping component 4 with bolts and wait for detection.

[0056] During detection: First step, select the corresponding detection program according to the detection requirements, and then the pipeline can be detected.

[0057] In the second step, first, the electric push rod 34 pushes the friction block 35 away from the side of the first gear 33, so that the second gear 352 can be engaged with the toothed rod 42. Similarly, the damping block 43 moves away from the side of the toothed rod 42 to unlock it. When the motor 36 drives the electric push rod 34 to rotate, it can drive the second gear 352 to engage with the toothed rod 42 for driving. At this time, the first gear 33 is not driven, and the toothed rod 42 drives the clamp block 45 and the mating block 463 to cooperate to clamp the inner or outer side of different pipes; after the pipe is clamped, the toothed rod 42 can be continuously driven to make the clamp block 45 and the mating block 463 generate extrusion strength detection on the inner or outer side of different pipes.

[0058] In the third step, after clamping the pipe, the electric sliding table 2 can be used to drive the carriage 21 to drive the mounting bracket 31 to move closer or farther away from each other, so as to perform compression and tearing strength detection on the pipe; or the electric push rod 34 pulls the friction block 35 to insert into the first gear 33 and engage with it for limiting, and the second gear 352 disengages from the side of the toothed rod 42 and does not engage with it, and the damping block 43 resets to generate frictional limit fixation on the toothed rod 42. At this time, when the motor 36 drives the electric push rod 34, it can drive the first gear 33 to engage with the toothed ring 32 to make the toothed ring 32 rotate, and the toothed ring 32 drives the connecting frame 41 as a whole to rotate. When the connecting frames 41 inside the two drive assemblies 3 rotate in the same direction, the pipe can be driven to rotate to directly observe whether there is damage on the side. When the connecting frames 41 inside the two drive assemblies 3 rotate in different directions, the pipe can be subjected to torsion strength test.

[0059] After detection: In the first step, when clamping the outer side of the pipe, the clamp block 45 and the mating block 463 inside one drive assembly 3 continue to clamp the pipe, and the clamp block 45 and the mating block 463 inside the other drive assembly 3 are driven to slightly move away from the outer side of the pipe. Subsequently, the connecting frame 41 is driven to rotate and cooperate with the carriage 21 to drive the mounting bracket 31 to move, so that the second detection block 465 can perform battery ultrasonic flaw detection on the side of the pipe. Similarly, the reverse operation can be performed to complete the flaw detection operation after the pipe strength detection, assisting the staff to judge the pipe strength.

[0060] In the second step, when clamping the inner side of the pipe, first disassemble the pipe, and then change it to clamp the outer side, and then the flaw detection operation can be performed as above to assist the staff to judge the pipe strength.

[0061] In the third step, after flaw detection, disassemble the pipe for subsequent other detections and measurements, reset all parts of the machine, and perform power-off after inspection, maintenance and repair.

[0062] As above, the connecting piece between the carriage 21 and the mounting bracket 31 can be replaced with a second group of electric sliding tables, so that the bending strength detection of the pipe can be performed, and it can be selected and built according to the on-site requirements and manufacturing costs.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
