Description

Technical Field

[0001] The present invention relates to a nondestructive testing device, in particular to an automatic positioning pressure vessel nondestructive testing device. The present invention also relates to a testing system, in particular to an automatic positioning pressure vessel nondestructive testing system, and belongs to the technical field of pressure vessel testing. Background Art

[0002] In the prior art, for example, the invention with application number 202010666110.7 discloses a nondestructive testing device for pressure vessels. In order to solve the problem that the operator performs nondestructive testing on the surface of the pressure vessel with a handheld detection probe, this detection method is prone to omission of the detection area, thereby failing to ensure that the detection range is fully covered, affecting the accuracy of the detection results, and thus causing certain safety hazards in the subsequent use of the pressure vessel. The nondestructive testing device for pressure vessels is provided with a circumferentially rotatable gear ring in the sleeve ring, and a detection probe is installed on the inner ring of the gear ring. The detection probe is driven to translate and rotate circumferentially at the same time by a translation mechanism, thereby realizing all-round detection of the pressure vessel, with a wide detection coverage, avoiding the existence of detection blind spots, improving the accuracy of the detection results, and ensuring product quality.

[0003] Similar to the above application, there are still some shortcomings:

[0004] During the use of the device, it is necessary to first pass through the inside of the ring, and then use the support frame to support and position the ends and bottom of the container. This is inconvenient for the installation, positioning, and loading and unloading of the container, affecting the detection rate. In addition, the support area will block the surface of the container, affecting the detection effect.

[0005] Therefore, an automatic positioning pressure vessel nondestructive testing device and testing system are designed to optimize the above problems. Summary of the invention

[0006] The main purpose of the present invention is to provide an automatic positioning pressure vessel nondestructive testing device and a testing system. By symmetrically arranging Y-shaped brackets on both sides of the base, the container can be supported, and a rotating assembly is arranged on the top of the Y-shaped bracket to control the uniform rotation of the container, and then the detection probe that reciprocates along the width direction of the base at the bottom of the first slider is used to detect the container. In addition, a slidable extrusion plate is arranged on the outside of the Y-shaped bracket, and the elastic force of the extrusion spring can automatically limit the end of the container during detection. After the detection is completed, the first slider on the top of the detection probe can squeeze the extrusion plate to release the positioning state of the container, making the installation and positioning of the container more convenient. In addition, the outer circumferential surface of the container will not be blocked, ensuring uniform detection. The rotating assembly composed of a motor, a shaft, a rotating roller, a driven gear, a driving gear, and a toothed belt can ensure the uniform rotation of the container. At the same time, a pulley assembly is arranged at the output shaft of the motor and the end of the reciprocating screw rod, so that the rotation of the container and the movement of the detection probe run synchronously, which is more convenient to control and more energy-saving to use. By arranging a mounting block and a conveying roller at one end of the base, the container can be automatically positioned. The discharging mechanism composed of a Y-shaped bracket, a baffle and a buffer pad can transport the container in the opposite direction according to the detection situation after detection, which is more convenient to use. By arranging a loading mechanism composed of a trapezoidal supporting block, a guardrail, a partition, a trapezoidal top block and a blocking component on the top of the base, the container can be evenly placed above the trapezoidal supporting block and the trapezoidal top block. The up and down movement of the trapezoidal top block can automatically transport the container in the direction of the Y-shaped bracket. In addition, when used in conjunction with an inclined plate, the inclined plate rises and falls with the trapezoidal top block, so that the container on the Y-shaped bracket can be automatically lifted up and placed on the rack. When the container on the trapezoidal top block rolls down, the container is automatically replaced and the loading operation is performed automatically, making the loading and unloading of the device more convenient. The lifting assembly consists of an upper groove on the partition, a lifting screw, a third slider, a lower groove, a transmission gear, and a rack. The third slider is connected to the trapezoidal top block, and the rack is connected to the extrusion plate. When the first slider squeezes the extrusion plate outward to release the limit state of the container end, the transmission control method is adopted to automatically control the rotation of the lifting screw to complete the loading and unloading operations. The loading and unloading and positioning control of the device are simple and convenient, and more practical.

[0017] The present invention also provides an automatic positioning pressure vessel nondestructive testing system, comprising the following steps:

[0018] Step 1: Before testing, place the cylindrical pressure vessel on the inclined surface of the trapezoidal support block parallel to the width direction of the base. Under the influence of the gravity of the container itself, the containers are placed neatly and closely together, and the containers are only arranged in a single row. In addition, the container at the bottom is close to the side of the partition.

[0019] Step 2: During the inspection, the motor starts and drives the reciprocating screw to rotate under the transmission control of the pulley assembly. The first slider on the reciprocating screw fits with the extrusion plate and controls the extrusion plate to move outward. During the movement of the extrusion plate, it drives the rack to move, thereby controlling the rotation of the transmission gear. The spacing between the two sets of extrusion plates increases to facilitate the loading of the container. At the same time, during the rotation of the lifting screw, the third slider and the trapezoidal top block are controlled to rise, and the container on the top of the trapezoidal top block is lifted. During the rising process of the trapezoidal top block, the L-shaped plate moves up under the action of the reset spring to prevent the container from entering under the trapezoidal top block. After the container passes over the top of the partition, it automatically rolls toward the Y-shaped bracket and fits on the inclined At the top of the plate, when the container is first detected, the baffle is located at one end of the side plate inside the strip groove to prevent the container from sliding out. After the container rolls down, the trapezoidal top block rises to the maximum height. When the motor continues to rotate, the first slider moves in the opposite direction, and the position of the trapezoidal top block drops and resets. The container falls into the inside of the Y-shaped bracket. Then, according to the diameter of the container, the position of the baffle is adjusted, and the distance between the inner side of the baffle and the side plate is adjusted to the diameter of the container. During the next loading and unloading, the inclined plate will lift the container that has been detected, and the container will drop along the inclined plate. The baffle blocks the container after detection, and the container after detection blocks the position of the pre-detected container, so as to continuously load and unload materials.

[0020] Step 3: After the container is placed on the top of the two sets of Y-shaped brackets, as the first slider moves toward the Y-shaped bracket and does not contact the extrusion plate, the extrusion plate squeezes and positions the end of the container under the force of the extrusion spring, and then the rotation of the motor controls the rotation roller to drive the container to rotate, and at the same time, the detection probe evenly scans and detects the surface of the container;

[0021] Step 4: After the inspection, the containers that fall on the top of the conveyor roller are transported in opposite directions, respectively, for unqualified and qualified products, according to the inspection conditions.

[0022] The beneficial effects of the present invention are:

Y-shaped brackets are symmetrically arranged on both sides of a base to support the container, and a rotating assembly is arranged on the top of the Y-shaped bracket to control the container to rotate at a uniform speed. The container is then tested by using a testing probe that reciprocates along the width direction of the base at the bottom of a first slider. In addition, a slidable extrusion plate is arranged on the outer side of the Y-shaped bracket. The elastic force of the extrusion spring can automatically limit the end of the container during testing. After the test is completed, the first slider on the top of the testing probe can squeeze the extrusion plate to release the positioning state of the container, making the installation and positioning of the container more convenient. In addition, the outer circumferential surface of the container will not be blocked, thereby ensuring uniform testing.

[0024] The rotating assembly consisting of a motor, a shaft, a rotating roller, a driven gear, a driving gear and a toothed belt can ensure the uniform rotation of the container. At the same time, a pulley assembly is provided at the output shaft of the motor and the end of the reciprocating screw rod, so that the rotation of the container and the movement of the detection probe can be synchronized, which makes the control more convenient and the use more energy-saving.

[0025] By arranging a discharging mechanism consisting of a mounting block, a conveying roller, a baffle and a buffer pad at one end of the base, the container can be conveyed in the opposite direction according to the detection situation after the detection, which is more convenient to use;

[0026] By arranging a loading mechanism composed of a trapezoidal support block, a guardrail, a partition, a trapezoidal top block and a blocking assembly on the top of the base, the container can be evenly placed above the trapezoidal support block and the trapezoidal top block, and the container can be automatically transported toward the Y-shaped bracket by utilizing the up and down movement of the trapezoidal top block. In addition, the inclined plate is used in conjunction with the trapezoidal top block, and the inclined plate rises and falls together with the trapezoidal top block, so that the container on the Y-shaped bracket can be automatically lifted up, and the container on the trapezoidal top block can be automatically replaced when the container rolls down, so as to perform automatic loading operation, making the loading and unloading of the device more convenient;

[0027] The lifting assembly is composed of an upper groove on the partition, a lifting screw, a third slider, a lower groove, a transmission gear and a rack. The third slider is connected to the trapezoidal top block, and the rack is connected to the extrusion plate. When the first slider squeezes the extrusion plate outward to release the limit state of the container end, the transmission control method is adopted to automatically control the rotation of the lifting screw to complete the loading and unloading operations.

DETAILED DESCRIPTION

[0037] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0039] The overall working principle is as follows: when loading, the loading mechanism 12 is used to transport the container to the top of the Y-shaped bracket 10, and during the loading process, the extrusion plate 4 is squeezed outward by the movement of the first slider 8 on the reciprocating screw 7, and the extrusion spring 5 is compressed. The spacing between the two groups of extrusion plates 4 is greater than the length of the container. After the loading is completed, the first slider 8 drives the detection probe 9 to move toward the direction of the container to release the extrusion state of the extrusion plate 4. The extrusion spring 5 resets and controls the extrusion plate 4 to fit the end of the container to fix the container. During detection, the detection probe 9 moves slowly along the length direction of the container, and the rotating component controls the container to rotate, so that the surface of the container can be evenly detected. After the detection is completed, the loading operation is performed again, and the detected container is pushed to the discharge mechanism 11, and then the product is discharged.

[0040] In this embodiment, the rotating assembly includes a motor 13, a pulley assembly 14, a shaft 15, a rotating roller 16, a driven gear 17, a driving gear 18 and a toothed belt 19. The motor 13 is installed on the side of the side plate 2, and the output end of the motor 13 is installed with the shaft 15. The shaft 15 passes through a group of extrusion plates 4 and is slidably connected with the extrusion plates 4. The shaft 15 passes through two groups of Y-shaped brackets 10. The top of the Y-shaped bracket 10 is evenly rotated and installed with a rotating roller 16. The ends of the rotating roller 16 are all installed with a driven gear 17. The driving gear 18 is rotatably installed at the middle position of the top of the Y-shaped bracket 10. A toothed belt 19 is meshed between the driven gear 17 and the driving gear 18, and the shaft 15 is fixedly connected to the driving gear 18.

[0041] Partial working principle: When controlling the rotation of the container, the starting motor 13 drives the shaft 15 to rotate, the shaft 15 drives the driving gear 18 to rotate, the driving gear 18 cooperates with the toothed belt 19 to control the rotation of the driven gear 17, and then simultaneously controls the rotation of multiple groups of rotating rollers 16, and utilizes the friction between the rotating rollers 16 and the container to drive the container to rotate at a uniform speed.

[0042] In this embodiment, a pulley assembly 14 is installed between the output end of the motor 13 and the end of the reciprocating screw rod 7 .

[0043] Partial working principle: During the rotation of the shaft 15, the reciprocating screw 7 is driven to rotate through the pulley assembly 14, while controlling the translation of the detection probe 9 and the rotation of the container, making the control more convenient and more energy-saving.

[0044] In this embodiment, the discharge mechanism 11 includes a mounting block 20, a conveying roller 21, a baffle 22, a buffer pad 23 and a translation assembly. The mounting block 20 is fixed at the top end of the base 1, and the mounting block 20 is parallel to the width direction of the base 1. The conveying roller 21 is evenly rotated on the top of the mounting block 20 along the length direction. A baffle 22 is slidably provided along the width direction at the middle position of the top of the mounting block 20. A buffer pad 23 is fixed on the side of the baffle 22 close to the side plate 2, and a translation assembly is provided at the bottom of the baffle 22.

[0045] Partial working principle: After the container is inspected and rolls down, the baffle 22 is used to block the container from rolling to the outside of the mounting block 20. After the container falls to the top of the mounting block 20, the bottom of the container contacts the conveying roller 21, and the rotation of the conveying roller 21 is controlled to move qualified and unqualified products to opposite sides.

[0046] In this embodiment, the translation assembly includes a strip groove 24, a second slider 25 and a translation screw 26. The strip groove 24 is opened at the top of the mounting block 20 along the width direction of the mounting block 20. The second slider 25 is slidably arranged inside the strip groove 24. The baffle 22 is vertically fixed on the second slider 25. The translation screw 26 is rotatably installed between the two ends of the strip groove 24. The translation screw 26 is threadedly connected to the second slider 25 and passes through the outside of the mounting block 20.

[0047] Local working principle: Due to the different diameters of the containers, during use, it is necessary to change the distance between the inner side of the baffle 22 and the side plate 2 by rotating the translation screw 26 to ensure that only one group of containers can be stored on the top of the mounting block 20 to avoid the accumulation of containers and cause poor discharge.

[0048] In this embodiment, the feeding mechanism 12 includes a trapezoidal support block 27, a guardrail 28, a partition 29, a trapezoidal top block 30, a vertical rod 31, a sliding hole 32, a blocking assembly 33 and a lifting assembly. The trapezoidal support block 27 is fixed to the top of the base 1 at one end away from the mounting block 20. The top of the trapezoidal support block 27 is an inclined surface, and the bottom end of the inclined surface faces the mounting block 20. The guardrail 28 is fixed at both ends of the trapezoidal support block 27. The partition 29 is vertically fixed to the end of the base 1 and is connected to the side plate 20. The side of the partition 29 is fitted with a trapezoidal top block 30 that slides vertically on one side of the partition 29 close to the trapezoidal supporting block 27. A lifting component for controlling the movement of the trapezoidal top block 30 is provided on the partition 29. A blocking component 33 is provided on the side of the trapezoidal supporting block 27 close to the trapezoidal top block 30 to prevent the container from moving below the trapezoidal top block 30. Vertical rods 31 are vertically fixed on the base 1 at both ends below the trapezoidal top block 30, and a sliding hole 32 cooperating with the vertical rod 31 is opened on the trapezoidal top block 30.

[0049] Local working principle: When loading, the lifting assembly is used to control the trapezoidal top block 30 to move up and fit on the surface of the partition 29, lift up the container above the trapezoidal top block 30, and after the container is higher than the partition 29, move toward the Y-shaped bracket 10 and fall to the top of the Y-shaped bracket 10.

[0050] In this embodiment, the lifting assembly includes an upper groove 34, a lifting screw 35, a third slider 36, a lower groove 37, a transmission gear 38 and a rack 39. The upper groove 34 is opened at the middle position of the top of the partition 29. The lifting screw 35 is rotatably installed on the inner bottom of the upper groove 34. The third slider 36 is vertically slidably provided inside the upper groove 34. The third slider 36 is threadedly connected to the lifting screw 35, and the third slider 36 is fixed on the trapezoidal top block 30. A lower groove 37 is opened at the bottom of the partition 29 along the length direction. The lifting screw 35 extends to the inside of the lower groove 37. A transmission gear 38 is fixed to the bottom end of the lifting screw 35. Racks 39 are meshed on both sides of the transmission gear 38, and the racks 39 are respectively located at both ends of the lower groove 37. The ends of the rack 39 away from the transmission gear 38 are respectively fixedly connected to the extrusion plate 4.

[0051] Local working principle: When loading, the motor 13 drives the reciprocating screw 7 to rotate, the first slider 8 moves toward the end, and squeezes the extrusion plate 4 outward. During the movement of the extrusion plate 4, it will drive the rack 39 to move, thereby controlling the rotation of the transmission gear 38. The transmission gear 38 drives the rotation of the third slider 36, thereby controlling the rise of the trapezoidal top block 30.

[0052] In this embodiment, an inclined plate 40 is fixed to one end of the third sliding block 36 away from the trapezoidal top block 30 , and the inclined plate 40 is inclined toward the Y-shaped bracket 10 .

[0053] Local working principle: the lifting and lowering of the third slider 36 will control the movement of the inclined plate 40. The inclined plate 40 will rise and fall vertically between the two groups of Y-shaped brackets 10. If there is a container after inspection inside the Y-shaped bracket 10, the inclined plate 40 will lift it up, and then the inspected container will roll along the inclined plate 40 to the top of the mounting block 20. At the same time, the inspected container will fit on the outer edge of the Y-shaped bracket 10, blocking the uninspected container rolling down from the trapezoidal top block 30, ensuring that the uninspected container is located above the Y-shaped bracket 10 after rolling down. After the inclined plate 40 is lowered and reset, the uninspected container automatically falls into the inside of the Y-shaped bracket 10.

[0054] In this embodiment, the blocking assembly 33 includes an L-shaped plate 41 and a return spring 42. The L-shaped plate 41 is vertically slidably arranged on the side of the trapezoidal support block 27. The return spring 42 is evenly arranged between the bottom of the L-shaped plate 41 and the base 1. The horizontal plate at the bottom end of the L-shaped plate 41 is located below the trapezoidal top block 30.

[0055] Local working principle: During the rising process of the trapezoidal top block 30 , the L-shaped plate 41 moves upward under the action of the return spring 42 , and the top end of the L-shaped plate 41 fits under the trapezoidal top block 30 to prevent the container from entering under the trapezoidal top block 30 .

[0056] like Figure 1-Figure 8 As shown, this embodiment provides a process of automatically positioning a pressure vessel nondestructive testing system as follows:

[0057] Step 1: Before testing, place the cylindrical pressure vessel parallel to the width direction of the base 1 on the inclined surface of the trapezoidal support block 27. Under the influence of the gravity of the container itself, the containers are neatly placed in close contact with each other, and the containers are only arranged in a single row. In addition, the container at the bottom is in close contact with the side of the partition 29;

[0058] Step 2: During the inspection, the motor 13 is started and drives the reciprocating screw 7 to rotate under the transmission control of the pulley assembly 14. The first slider 8 on the reciprocating screw 7 fits with the extrusion plate 4 and controls the extrusion plate 4 to move outward. During the movement of the extrusion plate 4, it drives the rack 39 to move, thereby controlling the rotation of the transmission gear 38. The spacing between the two sets of extrusion plates 4 increases to facilitate the filling of the container. At the same time, the lifting screw 35 controls the third slider 36 and the trapezoidal top block 30 to rise during the rotation, and lifts the container on the top of the trapezoidal top block 30. During the rising process of the trapezoidal top block 30, the L-shaped plate 41 moves upward under the action of the reset spring 42 to prevent the container from entering under the trapezoidal top block 30. After the container passes over the top of the partition 29, it automatically rolls toward the Y-shaped bracket 10 and Fitted on the top of the inclined plate 40, when the container is first detected, the baffle 22 is located inside the strip groove 24 near one end of the side plate 2 to prevent the container from sliding out. After the container rolls down, the trapezoidal top block 30 rises to the maximum height. When the motor 13 continues to rotate, the first slider 8 moves in the opposite direction, the position of the trapezoidal top block 30 drops and resets, and the container falls into the inside of the Y-shaped bracket 10. Then, according to the diameter of the container, the position of the baffle 22 is adjusted, and the distance between the inner side of the baffle 22 and the side plate 2 is adjusted to the diameter of the container. During the next loading and unloading, the inclined plate 40 will lift the container that has been detected, and the container will drop along the inclined plate 40. The baffle 22 blocks the container after detection, and the container after detection blocks the position of the pre-detected container, so as to carry out continuous loading and unloading.

[0059] Step 3: After the container is placed on the top of the two groups of Y-shaped brackets 10, as the first slider 8 moves toward the Y-shaped bracket 10 and does not contact the squeezing plate 4, the squeezing plate 4 squeezes and positions the end of the container under the force of the squeezing spring 5, and then the rotation of the motor 13 controls the rotation roller 16 to rotate and drive the container to rotate, and at the same time, the detection probe 9 evenly scans and detects the surface of the container;

[0060] Step 4: After the inspection, the containers that fall on the top of the conveying roller 21 are conveyed in opposite directions, respectively, according to the inspection conditions, and the unqualified and qualified products.
