Description

Technical Field

[0001] The present invention relates to the technical field of pipe production, in particular to a pipe sealing detection device. Background Art

[0002] In municipal road construction, pipe sealing testing is a key link to ensure the normal operation of the water supply and drainage system and avoid resource waste and environmental pollution. At present, common municipal road pipes include concrete pipes, plastic pipes (such as PE pipes, PVC-U double-wall corrugated pipes), metal pipes (such as ductile iron pipes) and composite pipes. If these pipes are not sealed well during laying and use, it will lead to water resource waste, sewage leakage, foundation settlement and other problems, seriously affecting the stability of urban infrastructure and the quality of life of residents.

[0003] At present, the common method for testing the tightness of pipes is the bubble test method, which is based on the air pressure test method. The staff uses plugs to seal both ends of the pipe and immerse the pipe in water. If there is a leak, gas will escape from the leak to form bubbles. The tightness is judged by observing the bubbles. However, although this method is simple and intuitive to operate, the tested pipes need to be dried to facilitate subsequent processing, which increases the time for pipe tightness testing. In addition, manually using plugs to seal each pipe one by one will further reduce the processing efficiency of the pipe, and thus cannot meet the large-scale testing needs of existing factories. Summary of the Invention

At this time, the pipe body on the belt conveyor cannot complete the unloading operation. When the pipe body moves to the top of the receiving frame, the reaction force of the torsion spring will push the receiving frame to reset. At this time, the pipe body above the belt conveyor will roll along the receiving frame track into between the two fixed pipes, so as to realize the purpose of automatic loading of the pipe body.

A detection mechanism is provided on the top of the processing table 1 and on one side of the trigger assembly. A conveying mechanism is provided on the rear side of the processing table 1. A sorting mechanism is provided on the bottom of the processing table 1 and between the two fixed brackets 2. A transmission mechanism is provided on the top of the processing table 1 and on one side of the fixed bracket 2.

When one of the pipe bodies 7 is rotated to the vacuum pump 14, the pipe body 7 will trigger the trigger mechanism, and the trigger mechanism controls the detection mechanism to move, so that the vent tube 26 in the detection mechanism is inserted into the specified vent hole 25. At this time, the vacuum pump 14 is used to evacuate the inside of the pipe body 7, and the vacuum degree is monitored by the vacuum gauge 18. Within the specified time, if the vacuum degree drops to a value that meets the requirements, it is determined that the sealing of the pipe body 7 is good. On the contrary, the pipe body 7 is judged to be a defective product. Through the above structure, the sealing performance of the pipe body 7 can be automatically detected, and the two ends of the pipe body 7 can be automatically sealed, thereby reducing the manual operation space and improving the processing efficiency of the pipe body 7. When the roller 6 continues to rotate, the pipe body 7 judged to have good sealing performance is thrown into the upper part of the qualified product box slot 16, and the pipe body 7 judged to have poor sealing performance is thrown into the upper part of the defective product box slot 17, thereby achieving the sorting purpose based on the automatic sealing detection function, and further improving the processing efficiency of the pipe body 7.

When the pipe body 7 squeezes the pressing block 19, the pressing block 19 will gradually slide downward, thereby triggering the pressure sensor 22. After the pressure sensor 22 detects a certain pressure, the control panel 3 controls the cylinder 13 in the detection mechanism to start. Two pressure sensors 22 are fixedly installed on the inner wall of the installation box 21, and two springs 20 are fixedly connected between the pressing block 19 and the inner wall of the installation box 21.

A sealing ring 28 is fixedly connected to one end of the vent pipe 26 close to the fixed pipe 23, and one end of the vent pipe 26 is inserted into the corresponding vent hole 25. By setting the sealing ring 28, the sealing performance between the vent pipe 26 and the vent hole 25 can be increased to improve the detection accuracy.

The belt conveyor 4 is fixedly connected to a rotating rod 33 on one side near the processing table 1. A receiving frame 34 is provided on the outside of the rotating rod 33. A torsion spring 32 is sleeved on the outer periphery of the rotating rod 33 and on both sides of the receiving frame 34. The receiving frame 34 is rotatably mounted on the outside of the rotating rod 33 through the torsion spring 32. When one of the pipe bodies 7 rotates to the receiving frame 34, the receiving frame 34 will be lifted up. At this time, the pipe body 7 on the belt conveyor 4 cannot complete the unloading operation. When the pipe body 7 moves above the receiving frame 34, the reaction force of the torsion spring 32 will push the receiving frame 34 to reset. At this time, the pipe body 7 above the belt conveyor 4 will roll along the receiving frame 34 track into between the two fixed pipes 23, so as to realize the purpose of automatic loading of the pipe body 7.

[0033] Reference Figure 3 The sorting mechanism includes a defective product box slot 17 opened inside the processing table 1 and located below the rotating roller 6. A qualified product box slot 16 is opened inside the processing table 1 and on one side of the defective product box slot 17. Several drive motors b31 are fixedly installed inside the transmission box 5. The qualified product box slot 16 and the defective product box slot 17 are used in conjunction with each other to load the corresponding pipe body 7. The output shafts of the drive motors b31 extend to the inside of the fixed slot 29 and are fixedly connected to the corresponding bidirectional screw rod 30.

[0034] Reference Figure 2 The transmission mechanism includes a driving motor a9 fixedly mounted on the top of the processing table 1, and a driving gear 10 is fixedly connected to the output shaft of the driving motor a9. The rotation of the output shaft of the driving motor a9 can drive the driving gear 10 to rotate, so that the driven gear 12 can be driven to rotate by the transmission belt 11, thereby realizing power transmission. The rotating shaft of the roller 6 passes through one of the fixed brackets 2 and is fixedly connected to the driven gear 12. The driving gear 10 and the driven gear 12 are connected by a transmission belt 11.

[0035] Reference Figure 4 and Figure 7 A bottom support block 35 used in conjunction with the receiving frame 34 is fixedly connected to the inside of the belt conveyor 4 and below the dumbbell-shaped seal 24. A built-in power supply for powering the drive motor b31 is fixedly installed inside the transmission box 5 to power the rotating drive motor b31.

[0036] Working principle: First, the control panel 3 is used to control the start of the driving motor a9. The rotation of the output shaft of the driving motor a9 can drive the driving gear 10 to rotate, so that the transmission belt 11 can be used to drive the rotation of the driven gear 12, and at the same time, the roller 6 and the pipe body 7 above it can be driven to rotate. When one of the pipe bodies 7 rotates to the receiving frame 34, the receiving frame 34 will be lifted up. At this time, the pipe body 7 on the belt conveyor 4 cannot complete the unloading operation. When the pipe body 7 moves above the receiving frame 34, the reaction force of the torsion spring 32 will push the receiving frame 34 to reset. At this time, the pipe body 7 above the belt conveyor 4 will roll along the track of the receiving frame 34 between the two fixed pipes 23, and through the rotation of the output shaft of the driving motor b31, the corresponding bidirectional screw rod 30 is driven to rotate, and then the two auxiliary brackets 8 can be driven to move toward or in the opposite direction, so as to drive the corresponding fixed pipe 23 to seal the two ends of the pipe body 7; When one of the pipe bodies 7 is rotated to the vacuum pump 14, the pipe body 7 will squeeze the pressing block 19, and then trigger the pressure sensor 22. After the pressure sensor 22 detects a certain pressure, the control panel 3 will control the cylinder 13 in the detection mechanism to start, and through the extension of the piston rod of the cylinder 13, the pusher 15 can be pushed to slide in the slide groove, so that the vent pipe 26 on the vacuum pump 14 can be inserted into the designated vent hole 25. At this time, the vacuum pump 14 can be used to evacuate the inside of the pipe body 7, and the vacuum degree can be monitored by the vacuum gauge 18. Within the specified time, if the vacuum degree drops to a value that meets the requirements, , then it is determined that the sealing of the pipe body 7 is good; otherwise, it is determined that the pipe body 7 is a defective product. Through the above structure, the automatic detection function of the sealing of the pipe body 7 can be realized, and the two ends of the pipe body 7 can be automatically sealed, thereby reducing the manual operation space and improving the processing efficiency of the pipe body 7. When the roller 6 continues to rotate, the pipe body 7 determined to have good sealing is thrown into the upper part of the qualified product box slot 16, and the pipe body 7 determined to have poor sealing is thrown into the upper part of the defective product box slot 17, thereby achieving the sorting purpose on the automatic detection function of sealing, and further improving the processing efficiency of the pipe body 7.
