Description

Technical Field

[0001] The present invention relates to the technical field of pressure pipeline detection, and in particular to a pressure pipeline detection device. Background Art

[0002] Pressure pipeline refers to all pipelines that are subjected to internal or external pressure. Pressure pipeline is a type of pipeline that is used to transport the medium inside it and is widely used in all aspects of life.

[0003] When producing pressure pipes, it is necessary to inspect whether the outer surface of the pressure pipes is damaged. In the prior art, the two ends of the pressure pipes are first sealed, and an air inlet pipe is provided at one of the sealed ends. The sealed pressure pipes are then placed in a water tank, and gas is input into the air inlet pipe to observe whether bubbles appear in the water. If bubbles appear, it indicates that the outer surface of the pressure pipe is damaged. However, this method is only applicable to pressure pipes that match a certain size of the "length, width and height" of the water tank. Pressure pipes that cannot be placed in the water tank cannot be inspected, and the water tank needs to be replaced, which is more troublesome and less practical, and it is difficult to meet the needs of inspectors.

[0070] The second screw rod 510 is driven to rotate by the output end of the second servo motor 511, so that the two sets of second clamping plates 512 can move closer to or farther from each other;

[0071] The fourth screw rod 520 is driven to rotate by the output end of the fourth stepper motor 521, so that the moving block 522 reciprocates along the surface of the fourth screw rod 520, which can drive the fork-type telescopic member 527 to extend or retract. When extending, the first inner cylinder 514, the second inner cylinder 515 and the third inner cylinder 516 all slide out from the outer cylinder 513, and when retracting, the first inner cylinder 514, the second inner cylinder 515 and the third inner cylinder 516 all retract into the inner part of the outer cylinder 513.

[0072] Working principle and use process of this device: In order to clearly describe the working principle of the present invention, we use Figure 1 To elaborate on the perspective;

[0073] First, the connecting ring 206 is kept in a vertical state, and the external mechanical arm on the right side delivers the pressure pipe body 105 to the through groove opened in the middle of the connecting ring 206, and drives the driving gear 210 to rotate through the output end of the second driving motor 211, so that the outer teeth 209, the rotating ring 207 and the inner teeth 208 rotate as a whole, driving all the driven gears 212 to rotate synchronously, so that all the racks 213 move synchronously toward the position close to the center of the connecting ring 206, thereby driving all the clamping members 214 to move synchronously toward the position close to the center of the connecting ring 206, clamping the pressure pipe body 105, and the pressure pipe body 105 is in a horizontal state;

[0074] The second screw rod 403 is driven to rotate by the output end of the second stepping motor 404, so that the first movable plate 405 moves to the middle of the left side of the machine body 1, so that the frame body 407 is located in the middle of the left side of the machine body 1;

[0075] The first electric push rod 304 remains in a vertical state, and the output end of the first electric push rod 304 extends to drive the connection frame 305 to move upward, so that the position of the connection frame 305 and the center of the connection ring 206 are located on the same straight line. The output end of the second electric push rod 310 extends, so that the two groups of first clamping plates 315 are close to the pressure pipe body 105, and the output end of the first servo motor 314 drives the first screw 312 to rotate, so that the two groups of first clamping plates 315 are close to each other, and the pressure pipe body 105 is also clamped. At this time, all the clamping members 214 release the clamping of the pressure pipe body 105, and then the first stepper motor 308 is used to move the first screw 312 to rotate. The output end drives the first screw rod 306 to rotate, so that the movable block 309 moves to the left, and the two groups of first clamping plates 315 pull the pressure pipe body 105 to the left, so that the left end of the pressure pipe body 105 abuts against the sealing gasket 408 inside the frame 407. Then, through the expansion and contraction of the output ends of the third electric push rods 409 on both sides and the rotation of the output ends of the transmission motors 411 on both sides, the two groups of cross heads 412 twist the threaded rod 413 into the interior of the frame 407, so that the two groups of clamping blocks 415 approach each other and clamp the outer wall of the left end of the pressure pipe body 105. At this time, the first electromagnet 406 is powered off to release the adsorption of the frame 407.

[0076] Next, the output end of the second stepper motor 404 rotates in the opposite direction, driving the first movable plate 405 to reset, and the above steps of pulling the pressure pipe body 105 to the left are repeated until the right end of the pressure pipe body 105 is located in the through groove opened in the middle of the connecting ring 206;

[0077] Secondly, the output end of the third stepper motor 504 drives the third screw rod 503 to rotate, so that the second movable plate 505 moves to the middle of the right side of the machine body 1, so that the two groups of second clamping plates 512 are also located in the middle of the right side of the machine body 1. At this time, the output end of the first stepper motor 308 rotates in the opposite direction to pull the pressure pipe body 105 to the right, so that the right end of the pressure pipe body 105 is located between the two groups of second clamping plates 512, and the outer cylinder 513, the first inner cylinder 514, the second inner cylinder 515, the third inner cylinder 516, the air blowing nozzle 517 and the sealing ring 518 are located inside the pressure pipe body 105 as a whole. Then, the output end of the second servo motor 511 drives the second screw rod 510 to rotate, so that the two groups of second clamping plates 512 are close to each other to clamp the right end of the pressure pipe body 105. At this time, the second electromagnet 506 is powered off to release the adsorption of the mounting plate.

[0078] Subsequently, the output end of the third stepper motor 504 rotates in the opposite direction, so that the second movable plate 505 is reset, and the pressure pipe body 105 is continuously pulled to the right through the two sets of second clamping plates 512, so that the left end of the pressure pipe body 105 is located in the through groove opened in the middle of the connecting ring 206, and all the clamping members 214 clamp the pressure pipe body 105, while the two sets of first clamping plates 315 release the clamping of the pressure pipe body 105 and reset, and the rotating shaft 203 is driven to rotate through the output end of the first driving motor 205, so that the pressure pipe body 105 is in an inclined state, and the left end of the pressure pipe body 105 faces the water tank 101;

[0079] The output end of the fourth driving motor 303 can drive the rotating sleeve 302 to rotate, and drive the connecting frame 305 to rotate obliquely, so that the connecting frame 305 and the pressure pipe body 105 are in a "parallel" state. Secondly, all the clamping members 214 release the clamping of the pressure pipe body 105, and the two groups of first clamping plates 315 clamp the pressure pipe body 105, and under the action of the output end of the first stepper motor 308, the pressure pipe body 105 is pushed into the water tank 101, which is equivalent to the "lower half" of the pressure pipe body 105 being tilted in the water;

[0080] Then, the output end of the fourth stepper motor 521 drives the fourth screw rod 520 to rotate, so that the fork-type telescopic member 527 is in an extended state, driving the air blowing nozzle 517 and the sealing ring 518 to move downward along the inner wall of the pressure pipe body 105 as a whole, so that the overall position of the air blowing nozzle 517 and the sealing ring 518 is adapted to the highest point of the part of the pressure pipe body 105 located in the water, and the air blowing nozzle 517 sprays air. Due to the coordinated use of the sealing ring 518 and the sealing gasket 408, the openings at both ends of the "lower half" of the pressure pipe body 105 are blocked, so that the gas will not escape from the "upper and lower openings", and the camera 104 shoots the process of whether there are bubbles in the water, so as to judge whether the pressure pipe body 105 is damaged or leaking;

[0081] After the inspection of the "lower half" of the pressure pipe body 105 is completed, all structures are reset. When the inspection of the "upper half" of the pressure pipe body 105 is carried out, the output end of the first electric push rod 304 contracts, driving the connection frame 305 to move downward. The purpose of this is to turn around without affecting the rotation of the pressure pipe body 105. The output end of the third drive motor 215 drives the driving wheel 216 to rotate. Driven by the belt 218, the driven wheel 217 rotates, driving the rotating rod 201 and the fixing seat 202 to rotate as a whole, so that the connecting ring 206 rotates, driving the horizontal pressure pipe body 105 to rotate, and realizing the U-turn. Repeat the above steps, so that the original "upper half" of the pressure pipe body 105 is underwater, and the inspection is realized;

[0082] In this way, the pressure pipe body 105 that is longer than the water tank 101 can be well inspected without replacing the water tank 101. It is convenient and fast, and the whole process is automated, meeting the needs of the staff.
