Description

Technical Field

[0001] This disclosure generally relates to the field of pressure vessel testing technology, and more specifically, to a non-destructive testing device for pressure vessels. Background Technology

[0002] Pressure vessels are closed containers that withstand pressure. They are often manufactured using welding processes. However, during welding, defects can occur due to various reasons such as inappropriate welding parameters or operational errors. These defects not only affect the quality and performance of the welded structure but may also lead to safety issues during use. Therefore, pressure vessels typically require non-destructive testing (NDT) after welding is completed.

[0003] Existing technology discloses an internal non-destructive testing device for pressure vessels. In this device, the connecting rod is hollow, and the wiring for the ultrasonic flaw detector, supplementary lighting, camera, and electric rotary table are all led out through the connecting rod and connected to a controller. The controller is electrically connected to the motor, and a display electrically connected to the camera is mounted on the controller. Operators can operate the device from the ground. It is evident that current non-destructive testing devices generally use electrical wires to connect the probe and the device body. In field operation, to accommodate longer probe detection distances, the required wires are typically very long. However, these wires, being scattered and easily tangled, can interfere with operation. Furthermore, the wires, exposed to the complex environment of the operating site for extended periods, are susceptible to impacts and friction, leading to wire damage and affecting the normal use and lifespan of the non-destructive testing device.

[0004] Therefore, how to provide a non-destructive testing device that reduces damage to wires caused by long-term exposure to the outside is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this disclosure is to address the shortcomings of the prior art by proposing a non-destructive testing device for pressure vessels, which improves the service life of the testing wires by storing and protecting them, thereby increasing the utilization rate of the non-destructive testing device.

[0006] To achieve the above objectives, this application provides a non-destructive testing device for pressure vessels, including a testing body, a collection and installation mechanism, a testing moving mechanism, and a wire winding mechanism. The wire winding mechanism includes a collection shaft, a collection worm spring, and a collection roller. The collection shaft and the collection roller are coaxially and fixedly connected, and the collection shaft and the collection worm spring are elastically connected.

[0007] Optionally, the collection and installation mechanism includes a storage box with a window on the upper surface of the storage box, and a wire winding mechanism is located inside the storage box. The collection shaft is rotatably connected to the middle position inside the storage box, and the collection worm spring is fixedly connected to the left side inside the storage box.

[0008] Optionally, the collection and installation mechanism also includes mounting protrusions, wherein two sets of mounting protrusions are provided and fixedly connected to the left and right sides of the lower surface of the storage box respectively; the storage box is located on the upper surface of the detection body, and the upper surface of the detection body is provided with mounting grooves that cooperate with the mounting protrusions.

[0009] Optionally, the collection and installation mechanism further includes mounting screw holes, mounting screws, mounting torsion blocks, and mounting stops, wherein mounting screw holes are respectively provided through the outer side of the mounting groove and the middle position of the mounting protrusion; the mounting screw is threaded into the inside of the mounting screw holes; the mounting torsion block is fixedly connected to the outer end face of the mounting screw; and the mounting stop is coaxially fixed on the mounting screw.

[0010] Optionally, the collection and installation mechanism also includes a protective baffle, baffle screw holes, and baffle bolts, wherein baffle screw holes are provided at the four corners of the protective baffle and at the positions opposite to the four corners on the front of the storage box.

[0011] Optionally, the detection moving mechanism includes a support body, a detection sliding arm, a detection rack, a detection motor, and a detection gear. The support body has an opening at its center, the detection sliding arm is slidably connected to the inner wall of the opening, and a detection probe is installed at the bottom of the detection sliding arm. The detection motor is fixedly connected to the upper surface of the support body, the detection gear is fixedly connected to the end of the output shaft of the detection motor, and the detection rack is fixedly connected to the right side of the detection sliding arm, with the detection rack and the detection gear meshing.

[0012] Optionally, the detection slide arm is hollow, and the detection wire of the detection probe is led out through the detection slide arm, passes through the window on the upper surface of the storage box, is wound around the collection roller, and is connected to the detection body through a plug. The detection body is electrically connected to the detection motor, and the detection body is equipped with a display that is electrically connected to the detection probe.

[0013] Compared with the prior art, the non-destructive testing device for pressure vessels provided in this disclosure has the following advantages:

[0014] (1) The present invention adopts a detection moving mechanism, which installs the support body on the pressure vessel. The detection motor drives the detection sliding arm to slide by meshing the detection gear fixed at the end of its output shaft with the detection rack fixed on the right side of the detection sliding arm. When the detection sliding arm slides, it can drive the detection wire to move, thereby ensuring that the detection sliding arm slides normally and that the detection probe at its bottom detects the pressure vessel.

[0015] (2) The present invention adopts a collection and installation mechanism. The storage box can store the test wire inside, which can prevent the test wire from being exposed to the outside for a long time and aging. Furthermore, the storage box is fixed to the upper surface of the test body by the installation screw, away from the ground, which can further protect the test wire from the influence of complex field environment such as moisture, thereby reducing the damage to the test wire and improving the service life of the test wire.

[0016] (3) The present invention adopts a wire winding mechanism, which enables the detection wire to be neatly wound on the collection roller, avoiding the problem that the non-destructive testing device cannot be used normally due to the detection wire being too long and randomly scattered and tangled. In addition, during normal use, when the detection wire needs to be "released" outward, the detection wire moves and drives the collection roller to rotate, which in turn drives the collection shaft to rotate. The collection worm spring, which is elastically connected to the collection shaft, is forced to tighten towards its center and stores elastic potential energy. When the detection wire needs to be "collected" inward, the elastic potential energy is released and converted into kinetic energy, which drives the collection shaft and the collection roller to rotate, thereby realizing the reset of the detection wire and further ensuring the neat storage and protection of the detection wire.

Detailed Implementation

[0026] This disclosure provides a non-destructive testing device for pressure vessels, which stores and protects the testing wires through the coordinated action of various mechanical components. This avoids the testing wires from aging due to long-term exposure to the outside, or from the testing device becoming unusable due to excessive length or random tangling of the testing wires. This reduces damage to the testing wires and increases their service life.

[0027] In a preferred embodiment of this disclosure, a non-destructive testing device for pressure vessels is provided, comprising a testing body 1, a collection and installation mechanism, a testing moving mechanism, and a wire winding mechanism. The wire winding mechanism includes a collection shaft 12, a collection worm spring 1201, and a collection roller 13. The collection shaft 12 and the collection roller 13 are coaxially and fixedly connected, and the collection shaft 12 and the collection worm spring 1201 are elastically connected. Further, the collection and installation mechanism includes a storage box 2, with a window on its upper surface. The wire winding mechanism is disposed inside the storage box 2, wherein the collection shaft 12 is rotatably connected to the middle position inside the storage box 2, and the collection worm spring 1201 is fixedly connected to the left side inside the storage box 2. The use of a wire winding mechanism ensures that the detection wire 5 is neatly wound around the collecting roller 13, avoiding the problem of the non-destructive testing device malfunctioning due to the detection wire 5 being too long and randomly scattered, causing it to become tangled. Furthermore, during use, when the detection wire 5 needs to be "released" outwards, its movement drives the collecting roller 13 to rotate, which in turn drives the collecting shaft 12 to rotate. The collecting worm spring 1201, elastically connected to the collecting shaft 12, is forced to tighten towards its center, storing elastic potential energy. When the detection wire 5 needs to be "retracted" inwards, the elastic potential energy is released, converting into kinetic energy, driving the collecting shaft 12 and the collecting roller 13 to rotate, thereby resetting the detection wire 5. Moreover, placing the wire winding mechanism inside the storage box 2 prevents the detection wire 5 from being exposed to the outside for extended periods, thus preventing aging and further ensuring the neat storage and protection of the detection wire 5.

[0028] In a preferred embodiment of this disclosure, the collection and installation mechanism further includes mounting protrusions 201, wherein two sets of mounting protrusions 201 are provided and fixedly connected to the left and right sides of the lower surface of the storage box 2, respectively; the storage box 2 is disposed on the upper surface of the detection body 1, and the upper surface of the detection body 1 is provided with mounting grooves 101 that cooperate with the mounting protrusions 201. Preferably, the mounting protrusions 201 are regular protrusions, and the number and position of the mounting protrusions 201 can be reasonably set according to the area of ​​the storage box 2. In addition, placing the storage box 2 on the upper surface of the detection body 1 can keep it away from the ground, which can further protect the detection wire 5 from the influence of complex on-site environments such as moisture, thereby reducing damage to the detection wire 5 and improving the service life of the detection wire 5.

[0029] In a preferred embodiment of this disclosure, the collection and installation mechanism further includes mounting screw holes 7, mounting screws 8, mounting torsion blocks 801, and mounting stops 802. Mounting screw holes 7 are respectively provided on the outer side of the mounting groove 101 and at the middle position of the mounting protrusion 201. The mounting screw 8 is threadedly connected to the inside of the mounting screw holes 7. The mounting torsion block 801 is fixedly connected to the outer end face of the mounting screw 8. The mounting stop 802 is coaxially fixed to the mounting screw 8. When the mounting groove 101 and the mounting protrusion 201 are engaged, the mounting screw holes 7 on the mounting protrusion 201 and the mounting screw holes 7 on the outer side of the mounting groove 101 are aligned, and then the mounting screw 8 can be threadedly connected to the inside of the mounting screw holes 7. Furthermore, the mounting torsion block 801 is fixedly connected to the outer end face of the mounting screw 8, and the two together serve as a bolt fixation. By applying force to the mounting torsion block 801, the mounting screw 8 rotates and advances inside the mounting screw holes 7, thereby fixing the storage box 2 and the detection body 1 together. Furthermore, the mounting block 802 is coaxially fixed on the mounting screw 8. Specifically, the mounting block 802 can be fixed in the middle of the contact surface between the mounting groove 101 and the mounting protrusion 201. This contact surface is close to the mounting torsion block 801 and acts as a gasket to prevent the mounting groove 101 and the mounting protrusion 201 from being subjected to external force and rubbing against each other, which would lead to loosening.

[0030] In a preferred embodiment of this disclosure, the collection and installation mechanism further includes a protective baffle 9, baffle screw holes 10, and baffle bolts 11, wherein the baffle screw holes 10 are respectively provided at the four corners of the protective baffle 9 and at the positions opposite to the four corners on the front of the storage box 2. The baffle screw holes 10 can be reasonably arranged at the positions on the front of the protective baffle 9 and the storage box 2 as needed, and then the two are fixed together by the baffle bolts 11.

[0031] In a preferred embodiment of this disclosure, the detection moving mechanism includes a support body 3, a detection sliding arm 4, a detection rack 401, a detection motor 6, and a detection gear 601. The support body 3 has a through-hole at its center, the detection sliding arm 4 is slidably connected to the inner wall of the opening, and a detection probe is mounted on the bottom of the detection sliding arm 4. The detection motor 6 is fixedly connected to the upper surface of the support body 3, the detection gear 601 is fixedly connected to the end of the output shaft of the detection motor 6, and the detection rack 401 is fixedly connected to the right side of the detection sliding arm 4, with the rack and gear meshing. Further, the detection sliding arm 4 is hollow, and the detection wire 5 of the detection probe is led out through the detection sliding arm 4, passes through a window on the upper surface of the storage box 2, winds around the collecting roller 13, and is connected to the detection body 1 via a plug. The detection body 1 is electrically connected to the detection motor 6, and the detection body 1 is equipped with a display electrically connected to the detection probe. When inspecting the inside of a pressure vessel, the support body 3 is installed on the pressure vessel, and the inspection sliding arm 4 and the inspection probe installed at its bottom are inserted into the pressure vessel. The inspection motor 6 is started, and the inspection motor 6 drives the inspection sliding arm 4 to move downward through the meshing of the inspection gear 601 fixed at the end of its output shaft and the inspection rack 401 fixed on the right side of the inspection sliding arm 4 (the inspection sliding arm 4 and inspection rack 401 are set to a reasonable length according to the requirements to ensure that the inspection probe can reach the bottom of the pressure vessel). When the inspection sliding arm 4 slides, it can drive the inspection wire 5 to move, thereby ensuring that the inspection sliding arm 4 slides normally, so that the inspection probe at its bottom can inspect the pressure vessel. The inspection results will be displayed on the inspection body 1, and then the technicians will make a reasonable judgment based on the pressure vessel parameters. Optionally, slide rails can be fixedly connected to both the front and rear sides of the inspection sliding arm 4, and slide tracks that cooperate with the slide rails are provided on the inner walls opposite the openings of the support body 3 to prevent the inspection sliding arm 4 from shifting.
