Description

Technical Field

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

[0002] In the construction of water conservancy projects, metal structures and pipelines are often built underwater to meet the requirements of water conservancy project construction. The pipelines are subject to various reverse external pressures and internal tensions of internal water pressure underground, causing damage to the pipelines. Therefore, during the production process of pipelines, it is necessary to perform strength testing on the pipelines so that the pipelines can meet the needs of subsequent water conservancy projects. The existing testing methods are to perform simple strength testing on the pipelines by stretching and extruding them with a tensile testing machine, or to perform extrusion strength testing on the sides of the pipelines by pressing blocks. This makes the testing of the pipelines too simple and cannot effectively simulate the various strength forces that the pipelines are subjected to when in use. In addition, water conservancy pipelines are of types such as straight pipes and corrugated pipes, and different methods of testing are required according to different types. Therefore, multiple sets of testing machines are required for testing, which increases the cost of production and manufacturing. Therefore, a testing device and method for water conservancy pipelines are proposed. Summary of the invention

[0007] Furthermore, the connecting frame is fixedly installed on the side of the gear ring, and slots are equidistantly provided on the side of the connecting frame. The gear rod is movably installed inside the slot, and a constraint block is fixedly installed on the wall of the slot. The damping block is clamped on the side of the gear rod, and a constraint rod is fixedly installed on the outer side of the connecting frame and the constraint rod passes through the damping block, and a return spring is fixedly connected between the damping block and the side of the constraint rod.

[0009] Furthermore, the auxiliary rod is arranged on the upper side of the workbench, a hole is opened on the side of the auxiliary rod, the telescopic rod is fixedly installed on the upper side of the workbench, and the support plate is clamped on the side position of the output end of the telescopic rod.

[0010] A method for using a detection device for a water conservancy project pipeline comprises the following steps: Before detection: First, select a corresponding detection method according to different pipelines for subsequent detection, and fix and install it; The second step is to clamp the outer side, and the electric slide drives the slide to move the two sets of drive components to the position between the support plates, place the pipe on the upper side of the support plate and insert it into the inner side of the mounting frame, and manually adjust the telescopic rod so that the support plate supports the pipe to an approximate height position, and wait for detection; The third step, when clamping the inner side, the electric slide drives the slide to move the two sets of drive components to the outer position 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 gear rod and install it on the side of the auxiliary rod through bolts, and then install one side of the auxiliary rod on the side of the gear rod through bolts. As above, place the pipe on the upper side of the support plate and adjust the position. After the pipe is sleeved on the side of the auxiliary rod, install the other end of the auxiliary rod on the side of the gear rod inside the other set of clamping components through bolts and wait for inspection.

[0011] Furthermore, the following steps are also included: During the inspection: the first step is to select a corresponding inspection program according to the inspection requirements, and then perform the inspection operation on the pipeline; 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 gear rod, and the damping block is away from the side of the gear rod to unlock it. When the motor drives the electric push rod to rotate, it can drive the second gear to engage and drive the gear rod. At this time, the first gear is not driven, and the gear rod drives the clamping block and the matching block to clamp the inside or outside of different pipes; at this time, after the pipe is clamped, the gear rod can continue to be driven to make the clamping block and the matching block produce extrusion strength detection on the inside or outside of different pipes; The third step is to clamp the pipe, drive the slide by the electric slide table to drive the mounting frame to move closer or farther away to perform compression and tear strength tests on the pipe; or the electric push rod pulls the friction block to insert into the first gear and engage with it, the second gear disengages from the side of the gear rod and does not mesh with it, and the damping block resets to produce friction limit fixation on the gear rod, then the motor drives the electric push rod to drive the first gear to mesh with the gear ring to rotate the gear ring, and the gear ring drives the connecting frame to rotate as a whole, when the connecting frames inside the two sets of drive components rotate in the same direction, the pipe can be driven to rotate to facilitate direct observation of whether the side is damaged, and when the connecting frames inside the two sets of drive components rotate in different directions, the pipe can be tested for torsional strength.

[0012] Furthermore, the following steps are also included: After the test: In the first step, when clamping the outer side of the pipeline, a group of internal clamping blocks and matching blocks of the driving assembly continue to clamp the pipeline, and another group of internal clamping blocks and matching blocks of the driving assembly are driven to slightly move away from the outer side of the pipeline, and then the connecting frame is driven to rotate and the matching slide frame drives the mounting frame to move, so that the battery ultrasonic flaw detection can be performed on the side of the pipeline through the second detection block. The reverse operation can complete the flaw detection operation after the pipeline strength test, and assist the staff to judge the pipeline strength; The second step is to first disassemble the pipe when clamping the inside of the pipe, and then change to clamping the outside, and then perform the same operation as above to assist the staff in judging the strength of the pipe; The third step is to dismantle the pipeline after flaw detection for subsequent testing and measurement, reset the machine components, perform inspection and maintenance, and then turn off the power.

[0013] Compared with the prior art, the present invention can achieve the following beneficial effects: 1. The present invention can perform multi-state detection on the pipeline by setting an electric slide, a drive component and a clamping component. It can simulate the strength detection of the pipeline under various conditions such as pressure on the outside and inside of the pipeline, twisting force on the side, and stretching and extrusion force on the pipeline. It can also adapt to different types of pipelines to stably clamp them to ensure stability during pipeline detection.

[0014] 2. The present invention can realize multi-state driving of various components of the clamping assembly by setting a driving assembly, and the internal structure is mechanically linked, which can stably ensure that the various components will not be damaged or displaced when force is applied during testing.

[0015] 3. The present invention, by providing components such as a gear ring, a first gear and a synchronous belt, can realize that a single driving motor can synchronously drive various components, thereby ensuring the driving stability and the subsequent concentric constraint clamping of the pipeline detection, thereby reducing the energy consumption of the equipment.

[0016] 4. The present invention can cooperate with the driving component to perform detection operations on the pipeline by setting up a clamping component, and the clamping block and the matching block can be adapted to clamp different pipelines to ensure the stability of clamping. After clamping, the driving component can be cooperated to drive the pipeline to rotate in the same direction and in different directions, thereby improving the versatility of the clamping component.

[0017] 5. The present invention provides a damping block and its peripheral components so that when the gear rod is not driven, the damping block can be clamped on its side to frictionally limit it, thereby ensuring the stability of the gear rod's pause. When the gear rod is driven, the damping block can be squeezed out of the side of the gear rod to avoid interference in the movement of the gear rod.

[0018] 6. The present invention sets a first detection block, a second detection block and peripheral components. The first detection block can detect the distance between the movable rods, determine whether the clamping block is flush with the matching block when clamping a straight pipe, and can assist in determining the major diameter of a computer when detecting a corrugated pipe, thereby assisting personnel in detecting pipeline data. The second detection block can cooperate with other components to rotate in contact with the side of the pipeline, perform electromagnetic ultrasonic flaw detection on the pipeline, and assist personnel in determining the strength of the pipeline.

[0019] 7. The present invention can cooperate with other components to clamp the inside of the pipe and detect the force strength of the inside by setting an auxiliary component, and the set support plate can provide auxiliary support for the pipe, which is convenient for stabilizing the pipe when it is not clamped. There is no need to manually maintain the height position of the pipe, ensuring that personnel can stay away from the machine during testing, thereby ensuring the safety of personnel operation.

An auxiliary component 5 that can assist in detection is arranged on the upper side of the workbench 1; The drive assembly 3 can be used to drive other components in multiple states, and the stability of the drive can be ensured; like Figures 4 to 7 As 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; The side of the friction block 35 away from the electric push rod 34 is fixedly installed with a connecting rod 351, and the connecting rod 351 is a convex round rod with a spline on the side. A second gear 352 is movably sleeved on the side of the connecting rod 351, and the second gear 352 is splined with the connecting rod 351, and the side rotation is limited. The second gear 352 is a circular gear that drives a limiting ring on the side. A first support cylinder 353 is fixedly connected between the second gear 352 and the side of the friction block 35, and the first support cylinder 353 is movably sleeved on the side position of the connecting rod 351. The first support cylinder 353 is a spring steel cylinder with a continuous "W"-shaped cross-section. A synchronous belt 354 is meshed and sleeved on the side of the second gear 352. The synchronous belt 354 is a rubber "O"-shaped belt with teeth on the inner side; specifically, when the electric push rod 34 pushes the friction block 35 to disengage from the first gear 33, the connecting rod 351 can move accordingly, and the first support cylinder 353 elastically supports the second gear 352, so that the second gear 352 can be elastically engaged with other components later. The force applied to the side of the friction block 35 can be used to determine whether the second gear 352 is engaged in place. The rotation of the friction block 35 can drive the second gear 352 to rotate and engage with the later components through the connecting rod 351. The synchronous belt 354 provided in addition can synchronize all the second gears 352, so that a group of driving ends can drive the various components to move synchronously, which is convenient for concentric clamping constraints when clamping the pipe; The clamping assembly 4 can be driven by the driving assembly 3 in different states, so that it can stably clamp various pipes and perform multi-state detection operations; like Figures 4 to 6 and Figures 8 to 10As shown, the clamping assembly 4 includes a connecting frame 41 fixedly mounted on the side of the gear ring 32 and the connecting frame 41 is attached to the wall of the installation cavity 311. The connecting frame 41 is a circular ring frame. Slots 411 are equidistantly arranged in a circular array on the side of the connecting frame 41 corresponding to the notch of the installation frame 31 and the side position of the second gear 352. The slots 411 are rectangular slots. A gear rod 42 is movably mounted inside the slot 411 and extends from the inside of the installation cavity 311. The gear rod 42 is a U-shaped rectangular rod with teeth on the side. A restraint block 421 is fixedly installed on the wall surface of the slot 411 and is movably arranged at the inner side of the gear rod 42. The restraint block 421 is a rectangular block. A damping block 43 is clamped on the side of the gear rod 42 and is arranged on the outer side of the connecting frame 41 corresponding to the connecting rod 351. The damping block 43 is an "F"-shaped folding block made of elastic rubber material. A restraint rod 431 is equidistantly fixedly installed on the outer side of the connecting frame 41 corresponding to the position of the damping block 43 and the restraint rod 431 penetrates the damping block 43. The restraint rod 431 is a "T" The shaped cylindrical rod has a return spring 432 fixedly connected between the damping block 43 and the side of the constraint rod 431, and the return spring 432 is movably sleeved on the side of the constraint rod 431; specifically, when the friction block 35 is pushed, the second gear 352 is elastically supported and elastically obliquely inserted into the side of the gear rod 42 for meshing, and the synchronous connecting frame 41 can drive the gear ring 32 to rotate slightly. At this time, the first gear 33 is not restricted by the drive, and the second gear 352 is meshed with the gear rod 42 to drive it to reciprocate under the limit constraint of the constraint block 421, wherein Before the gear rod 42 is meshed with the second gear 352, the connecting rod 351 pushes and squeezes the side of the damping block 43 so that the damping block 43 is constrained by the constraint rod 431 to squeeze the reset spring 432 to deform, so that the damping block 43 is separated from the side of the gear rod 42, and the gear rod 42 can be meshed and moved with the second gear 352 without interference. When the friction block 35 is pulled to reset and insert into the first gear 33, the damping block 43 is supported by the elastic force of the reset spring 432 to reset and clamp at the side position of the gear rod 42, which acts as a friction limiter to keep the clamping stable. A mounting block 44 is provided on the side of the gear rod 42 and the mounting block 44 is fixedly installed on the side of the gear rod 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 gear rod 42. The clamping block 45 is a comb-shaped block with an arc on one side. An active cavity 46 is equidistantly opened on the side of the concave part of the clamping block 45. The active cavity 46 is a cylindrical cavity with a convex cross-section. An active rod 461 is movably installed inside the active cavity 46 and the active rod 461 extends out of the active cavity 46. The active rod 461 is a cylindrical rod with a cross-section. A second support cylinder 462 is fixedly connected between the walls of the movable cavity 46. The second support cylinder 462 is a spring steel cylinder with a continuous "W"-shaped cross section. 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 position 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 arranged on the wall of the partial movable cavity 46 corresponding to the position of the second support cylinder 462. The first detection block 464 is a distance sensor (this technical solution is not described in detail, and a model that can detect small and medium distances is sufficient). A second detection block 465 is provided. The second detection block 465 is a convex cylinder integrating an electromagnetic ultrasonic sensor (this type of sensor is coupled with a coupling agent and polished for easier operation), a battery block and a remote information transmitter. The second detection block 465 can be threadedly mounted inside the matching block 463 and the clamping block 45; specifically, the clamping block 45 can be fixedly mounted on the side of the gear rod 42 through the mounting block 44, and the gear rod 42 drives the clamping block 45 to clamp the pipe. When the pipe is straight, the clamping block 45 is directly clamped on its side, and the synchronous matching block 463 is squeezed and slides into the inner side of the clamping block 45 to be flush with it. When the pipe is corrugated, the The protrusion of the clamp block 463 can continue to squeeze the matching block 463 to make it continue to slide into the inner side of the clamp block 45, so that the clamp block 45 and the matching block 463 can cooperate to clamp the corrugated pipe, ensuring the stability of clamping different pipes. The first detection block 464 detects the distance of the movable rod 461. In the case of a straight pipe, it can be detected and determined that the clamp block 45 and the matching block 463 are level. In the case of a corrugated pipe, the first detection block 464 can detect the distance of the movable rod 461 to obtain the major diameter of the corrugated pipe, and thus the minor diameter can be calculated to avoid the difficulty in detecting the outer diameter of the corrugated pipe. In addition, the second detection block 465 can be used to perform electromagnetic ultrasonic flaw detection on the straight pipe and the corrugated pipe in the same manner as above; The auxiliary component 5 can assist in pipeline detection, expand the pipeline detection method, and improve the detection diversification; like Figures 1 to 3As shown, the auxiliary component 5 includes an auxiliary rod 51 equidistantly arranged on the upper side of the workbench 1, the auxiliary rod 51 is a rectangular rod with a comb-shaped side, an opening 511 penetrating the auxiliary rod 51 is opened on the side of the auxiliary rod 51, and the opening 511 is a round hole, and a telescopic rod 52 is symmetrically and equidistantly installed vertically and fixedly on the upper side of the workbench 1 corresponding to the side position of the electric slide table 2, the telescopic rod 52 is a round rod that can be manually telescopically adjusted, and can also be replaced by an electric push rod 34, a support plate 53 is arranged on the upper side of the telescopic rod 52, and the support plate 53 is clamped at the side position of the output end of the telescopic rod 52, and the support plate 53 is an arc-shaped plate; specifically, the support plate 53 can be adjusted by the telescopic rod 52 The height position allows the telescopic rod 52 to provide support and assistance before pipeline inspection, which facilitates the installation and inspection of the pipeline, and the support plate 53 is detachable to avoid interference caused by the slide 21 driving the drive assembly 3 to move. The auxiliary rod 51 can be installed on the side of the toothed rod 42 with the help of bolts, so that the toothed rod 42 can drive the auxiliary rod 51 to move, and the mounting block 44 is installed at any position on the side of the auxiliary rod 51 by bolts, and the auxiliary rod 51 with the clamping block 45 is set on the inner side of the pipeline, so that the toothed rod 42 can drive the clamping block 45 and its surrounding components to squeeze and clamp the inner side of the pipeline, so that the inside of the pipeline can be squeezed and driven to rotate.

Before moving, the support plates 53 are removed to avoid interference. The mounting block 44 on the side of the gear rod 42 is first disassembled and installed on the side of the auxiliary rod 51 by bolts, and then one side of the auxiliary rod 51 is installed on the side of the gear rod 42 by bolts. After the pipe is placed on the upper side of the support plate 53 and adjusted to the position and the pipe is sleeved on the side of the auxiliary rod 51, the other end of the auxiliary rod 51 is installed on the side of the gear rod 42 inside the other set of clamping components 4 by bolts, and then wait for detection; During inspection: The first step is to select the corresponding inspection program according to the inspection requirements, and then perform inspection operations on the pipeline; 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 gear rod 42, and the damping block 43 is unlocked away from the side of the gear rod 42. When the motor 36 drives the electric push rod 34 to rotate, the second gear 352 can be driven to engage and drive the gear rod 42. At this time, the first gear 33 is not driven, and the gear rod 42 drives the clamping block 45 and the matching block 463 to clamp the inside or outside of different pipes; at this time, after the pipe is clamped, the gear rod 42 can continue to be driven to make the clamping block 45 and the matching block 463 produce extrusion strength detection on the inside or outside of different pipes; The third step is to clamp the pipe after the slide 21 is driven by the electric slide 2 to drive the mounting frame 31 to move closer or further away to perform compression and tear strength tests 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 to limit the position, the second gear 352 disengages from the side of the gear rod 42 and does not mesh with it, and the damping block 43 resets to produce friction limit fixation on the gear rod 42, at this time, the motor 36 drives the electric push rod 34 to drive the first gear 33 to mesh with the ring gear 32 to rotate the ring gear 32, and the ring gear 32 drives the connecting frame 41 to rotate as a whole, and when the connecting frames 41 inside the two sets of drive components 3 rotate in the same direction, the pipe can be driven to rotate, so as to directly observe whether the side is damaged, and when the connecting frames 41 inside the two sets of drive components 3 rotate in different directions, the pipe can be tested for torsional strength.

[0025] After the test: In the first step, when clamping the outside of the pipe, one set of internal clamping blocks 45 and matching blocks 463 of the driving assembly 3 continue to clamp the pipe, and the other set of internal clamping blocks 45 and matching blocks 463 of the driving assembly 3 are driven slightly away from the outside of the pipe, and then the connecting frame 41 is driven to rotate and the matching slide 21 drives the mounting frame 31 to move, so that the second detection block 465 can be used to perform battery ultrasonic flaw detection on the side of the pipe. The reverse operation can complete the flaw detection operation after the pipe strength test, and assist the staff to judge the strength of the pipe; The second step is to first disassemble the pipe when clamping the inside of the pipe, and then change to clamping the outside, and then perform the same operation as above to assist the staff in judging the strength of the pipe; The third step is to dismantle the pipeline after flaw detection for subsequent testing and measurement, reset the machine components, perform inspection and maintenance, and then turn off the power.

[0026] As described above, the connector between the slide 21 and the mounting frame 31 can be replaced with a second set of electric slides, so that the bending strength of the pipeline can be tested. The selection and construction can be based on site requirements and manufacturing costs.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
