The two push rods of the bidirectional cylinder 3 in this embodiment are in the same straight line, and the moving directions are opposite. Two push rods of the bidirectional cylinder 3 are fixedly provided with first electric-driven rollers 4. Both the bidirectional cylinder and the electrically driven roller are prior art and will not be described in detail herein.
The plurality of first roller assemblies are arranged in parallel, and two first electric driving rollers 4 in each first roller assembly are symmetrically arranged about the axis of the first fixing rod 2.
The bidirectional cylinder 3 drives the two first electrically-driven rollers 4 to act, so that the distance between the two electrically-driven rollers in the same group is changed to adapt to pressure containers with different inner diameters. The supporting mechanism can stably support the pressure container.
In use, the distance between two first electrically driven rollers 4 in the same initial group is smaller than the inner diameter of the pressure vessel. One end of the pressure container is sleeved on the supporting mechanism, and the first electric driving roller 4 is in contact with the inner wall of the pressure container and supports the pressure container. A plurality of first electricity drive gyro wheel 4 all contact with pressure vessel's inner wall, make pressure vessel more stable. Then the two-way cylinder 3 is started, and the two push rods of the two-way cylinder 3 extend, so that the distance between the two first electrically-driven rollers 4 in the same group is gradually increased. The first electrically driven roller 4 pushes the pressure vessel upwards. When the length of the first roller assembly, namely the distance between the outer edges of the two first electrically-driven rollers 4, is equal to the inner diameter of the pressure vessel, the bidirectional air cylinder 3 cannot be extended, and the pressure vessel cannot move up and down along the supporting mechanism, so that the pressure vessel is more stable and is not easy to shake.
The detection mechanism comprises a second fixed rod 5, a second roller component, an arc-shaped electric slide rail 11, a third roller component, a connecting strip 16 and a magnetostrictive ultrasonic guided-wave flaw detector 17.

The upper end of the first sliding rod 7 is fixedly provided with a first baffle. The first baffle keeps the first slide bar 7 connected with the second fixed rod 5, and prevents the first slide bar 7 from being separated from the second fixed rod 5. The first spring 8 is sleeved on the second sliding rod 14 and is positioned between the second mounting plate and the second fixed rod 5. When the pressure container moves upwards, the second electrically-driven roller 6 is pushed to move upwards, and then the first spring 8 is compressed, so that the first spring 8 has elastic potential energy, and the second electrically-driven roller 6 is abutted against the surface of the pressure container.
One end of the second fixing rod 5 close to the fixing seat 1 is in sliding fit with the arc-shaped electric slide rail 11, and the arc-shaped electric slide rail 11 slides along the length direction of the second fixing rod 5.
Specifically, a first linear motor 9 is arranged in the length direction of the second fixing rod 5, and the first linear motor 9 is a U-shaped groove linear motor. An arc-shaped electric slide rail 11 is mounted on the first linear motor 9 through a first slide block 10. One end of the first sliding block 10 is fixedly connected with the first linear motor 9, and the other end of the first sliding block 10 is fixedly connected with the arc-shaped electric sliding rail 11. The first linear motor 9 drives the arc-shaped electric slide rail 11 to move along the second fixing rod 5.
The third roller component is arranged on the arc-shaped electric slide rail 11 through a second slide block 12. One end of the second sliding block 12 is fixed on the arc-shaped electric sliding rail 11, and the other end of the second sliding block 12 is longitudinally connected with the third roller component in a sliding manner.
The arc-shaped electric slide rail 11 is a second linear motor with an arc-shaped guide rail and comprises a second linear motor body and the arc-shaped guide rail. The second linear motor body is matched with the arc-shaped guide rail to drive the second roller assembly to move along the arc-shaped guide rail. The circle center of the arc-shaped guide rail is positioned on the axis of the first fixing rod 2. Thus, when the arc-shaped electric slide rail 11 drives the third roller assembly to move, the third roller assembly can keep abutting against the surface of the pressure container.
The third roller assembly comprises a third electric driving roller 13, a second mounting plate and a second connecting piece.
The second link comprises a second slide 14, a second spring 15.

A second slide hole is formed in the second slide block 12, the upper end of the second slide rod 14 penetrates through the second slide hole, and the second slide rod 14 is in sliding fit with the second slide block 12 through the second slide hole. The upper end of the second sliding rod 14 is fixedly provided with a second baffle. The second stop prevents the second slide 14 from disengaging from the second slide 14. The second spring 15 is sleeved on the second slide bar 14. A second spring 15 is located between the second slider 12 and the second mounting plate.
The connecting strip 16 is fixedly mounted between the first mounting plate and the second mounting plate. Specifically, the connecting strip 16 is flexibly connected with the first mounting plate and the second mounting plate through elastic cloth. The connecting strip 16 is made of a flexible material. The magnetostrictive ultrasonic guided-wave flaw detector 17 is fixedly arranged on the connecting strip 16. The magnetostrictive ultrasonic guided-wave flaw detectors 17 are distributed on the connecting strips 16 in sequence. The magnetostrictive ultrasonic guided wave flaw detector 17 is equivalent to the second electrically-driven roller 6 and the third electrically-driven roller 13 in position, so that when the second electrically-driven roller 6 and the third electrically-driven roller 13 are abutted against the pressure container, the magnetostrictive ultrasonic guided wave flaw detector 17 is tightly attached to the surface of the pressure container.
The arc-shaped electric slide rail 11 moves along the length direction of the second fixing rod 5 under the action of the first linear motor 9, so that the magnetostrictive ultrasonic guided-wave flaw detector 17 can adapt to pressure containers with different lengths, and the pressure containers with different lengths can be conveniently detected. When the arc-shaped electric slide rail 11 moves along the second fixing rod 5 to the second roller assembly, the connecting bar 16 becomes loose. When third electricity drive gyro wheel 13 moves pressure vessel directly over, stop first linear electric motor 9, start arc electric slide rail 11, make third roller components along the motion of arc guide rail, make connecting strip 16 twine on pressure vessel, and then make connecting strip 16 become tight, make magnetostrictive ultrasonic guided wave flaw detector 17 hug closely with pressure vessel surface, magnetostrictive ultrasonic guided wave flaw detector 17 is to pressure vessel's axial arrangement compacter, it is more clear to make the formation of image like this, the monitoring blind area can not appear, the testing result is more accurate.
The working principle is as follows: in an initial state, the bidirectional cylinder 3 is in a contraction state, the connecting strip 16 is in a tension state, and the detection surface of the magnetostrictive ultrasonic guided-wave flaw detector 17 and the lowest points of the second electric-driven roller 6 and the third electric-driven roller 13 are positioned on the same surface.
During the use, the open end cover that will need the pressure vessel that detects is established on first dead lever 2, and up to the deepest of first dead lever 2 stretching into pressure vessel, first electricity drive gyro wheel 4 and pressure vessel's inner wall contact this moment, prop up pressure vessel, and supporting mechanism is located the top at pressure vessel center. The detection mechanism is outside the pressure vessel and is not in contact with the pressure vessel. Then the first linear motor 9 is started, the first linear motor 9 drives the arc-shaped electric sliding rail 11 to move, the arc-shaped electric sliding rail 11 drives the third roller assembly to move towards the direction close to the second roller assembly, and the first linear motor is closed until the third electric driving roller 13 is positioned right above the pressure container. At which point the connecting strip 16 becomes loose.
Then start two-way cylinder 3, two-way cylinder 3's push rod drives first electricity and drives gyro wheel 4 and remove to the direction that deviates from first dead lever 2, two first electricity in the same group drive the distance between gyro wheel 4 crescent gradually, and then drive pressure vessel rebound, when the distance between 4 outward flanges of two first electricity in the same group drives the gyro wheel equals pressure vessel's internal diameter, two-way cylinder 3 can not extend again, pressure vessel stops the rebound, then close two-way cylinder 3. At this time, the distance between the outer edges of the two first electrically driven rollers 4 in the same group is equal to the inner diameter of the pressure vessel, and the first electrically driven rollers 4 abut on the inner wall of the pressure vessel, so that the pressure vessel can not move upwards or downwards along the first electrically driven rollers 4 any more, and the pressure vessel is easier to keep stable.
In the process, the upward movement of the pressure container gradually approaches the second electrically-driven roller 6 and the third electrically-driven roller 13, and pushes the second electrically-driven roller 6 and the third electrically-driven roller 13 to move upward. The first slide bar 7 moves upwards, and the first spring 8 is compressed to have elastic potential energy, so that the second electrically driven roller 6 is abutted on the pressure container. The second slide 14 moves upwards and the second spring 15 is compressed and has elastic potential energy, so that the third electrically driven roller 13 abuts against the pressure vessel.
Therefore, the pressure vessel is more easily kept stable under the clamping action of the first electrically-driven roller 4, the second electrically-driven roller 6 and the third electrically-driven roller 13, and the pressure vessel is kept stable when rotating. And the first electric drive roller 4, the second electric drive roller 6, the third electric drive roller 13 and the pressure container are prevented from slipping and being incapable of rotating.
Then the arc-shaped electric slide rail 11 is started to enable the second linear motor body to move along the arc-shaped guide rail. And then drives the third roller assembly to move along the arc-shaped guide rail, so that the end of the connecting strip 16 connected with the second mounting plate moves along the arc-shaped guide rail. The connecting strip 16 is wound on the surface of the pressure container, and the connecting strip 16 is gradually tensioned because the connecting strip 16 is gradually wound on the surface of the pressure container, so that the magnetostrictive ultrasonic guided-wave flaw detector 17 is attached to the surface of the pressure container. The second linear motor is then turned off. The magnetostrictive ultrasonic guided-wave flaw detector 17 is bonded with the pressure container and the pressure container, so that the detection imaging is clearer and the result is more accurate.
Then start first electricity and drive gyro wheel 4, second electricity and drive gyro wheel 6, third electricity and drive gyro wheel 13, first electricity drives gyro wheel 4, second electricity and drives gyro wheel 6, third electricity and drive gyro wheel 13 and rotate and drive the pressure container and rotate. And starting the magnetostrictive ultrasonic guided-wave flaw detector 17 to perform flaw detection on the pressure container. The pressure container rotates stably, so that the magnetostrictive ultrasonic guided-wave flaw detector 17 moves on the surface of the pressure container, and further comprehensive flaw detection is performed on the pressure container.
