Description

Technical Field

[0001] This utility model relates to the field of composite pipe testing technology, and in particular to a steel wire mesh testing device for multi-reinforced steel-plastic composite pipes. Background Technology

[0002] Multiple reinforced steel-plastic composite pipes are widely used in municipal water supply and drainage, oil and gas transportation and other fields due to their excellent pressure resistance and corrosion resistance. Among them, steel wire mesh is the core reinforcing structure. Problems such as deviation in its laying position, broken wires, and uneven winding density will directly lead to a decrease in the overall strength of the pipeline and cause safety accidents such as leakage and bursting.

[0003] The existing steel wire mesh inspection devices for multi-reinforced steel-plastic composite pipes still have the following problems: 1. Some steel wire mesh inspection devices for multi-reinforced steel-plastic composite pipes cannot drive the pipe to rotate after the pipe is fixed, which affects the comprehensive inspection coverage of the steel wire mesh in the circumferential direction of the pipe. This makes it difficult to find steel wire mesh defects in local areas of the pipe circumference, resulting in blind spots in the inspection and failing to ensure the integrity and accuracy of the steel wire mesh inspection results in the pipe.

[0004] The detection head of the multi-reinforced steel-plastic composite pipe wire mesh inspection device can only move back and forth, but cannot move up and down. This affects the adaptability of the inspection to pipes with different outer diameters. It is not conducive to adjusting the distance between the detection head and the outer wall of the pipe to achieve accurate correspondence with each layer of wire mesh. As a result, the detection head may experience signal attenuation or interference due to improper distance, making it impossible to accurately identify the positional deviation and defects of the wire mesh, thus affecting the inspection accuracy. Utility Model Content

[0005] The purpose of this utility model is to provide a wire mesh inspection device for multi-reinforced steel-plastic composite pipes, which solves the problems of existing multi-reinforced steel-plastic composite pipe wire mesh inspection devices being unable to rotate the pipe after it is fixed, thus affecting the comprehensive inspection coverage of the wire mesh in the circumferential direction of the pipe and the inspection head being able to move back and forth but not up and down, thus affecting the adaptability inspection of pipes with different outer diameters.

[0006] To achieve the above objectives, a testing device for steel wire mesh in multi-reinforced steel-plastic composite pipes is provided, including a testing platform. A mounting frame is fixedly installed on the left end of the testing platform. A second motor is fixedly installed on one side of the mounting frame. The output end of the second motor passes through the mounting frame and is connected to a mounting ring via a coupling. A clamping assembly is provided inside the mounting ring.

[0007] The clamping assembly includes a slider, an arc-shaped baffle, a screw, an arc-shaped clamp, and a silicone pad. The mounting ring has four symmetrical openings, and a slider is slidably installed in each of the four openings. An arc-shaped clamp is fixedly pressed to the front end of the slider, and a silicone pad is provided at the front end of each arc-shaped clamp. An arc-shaped baffle is fixedly installed to the rear end of each slider. The front end of the mounting ring has four symmetrical threaded holes, and a screw is provided in each of the four threaded holes. One end of the screw abuts against the slider.

[0008] According to the aforementioned multi-reinforced steel-plastic composite pipe wire mesh testing device, two arc-shaped fixing frames are symmetrically fixedly installed on the right end of the testing platform, and two fixing blocks are symmetrically fixedly installed on one end of each arc-shaped fixing frame.

[0009] According to the aforementioned multi-reinforced steel-plastic composite pipe wire mesh testing device, a rotating rod is rotatably installed between the two fixed blocks, and an arc-shaped fixing plate is fixedly installed in the middle of the rotating rod.

[0010] According to the aforementioned multi-reinforced steel-plastic composite pipe wire mesh testing device, the other end of each arc-shaped fixing plate is threaded onto the other end of an arc-shaped fixing frame, and bolts are threaded onto the other end of both the arc-shaped fixing plate and the arc-shaped fixing frame.

[0011] According to the aforementioned multi-reinforced steel-plastic composite pipe wire mesh testing device, support legs are fixedly installed at the four corners of the bottom of the testing platform, and two slots are opened on both sides of the testing platform. A sliding rod is fixedly installed in one slot, and a lead screw is rotatably installed in the other slot.

[0012] According to the aforementioned multi-reinforced steel-plastic composite pipe wire mesh testing device, one end of the lead screw passes through the testing platform and is connected to a motor via a coupling. The motor is fixedly installed at one end of the testing platform.

[0013] According to the aforementioned multi-reinforced steel-plastic composite pipe wire mesh testing device, a sliding frame is fitted onto the screw rod, and the other end of the sliding frame is slidably mounted on the slide rod.

[0014] According to the aforementioned multi-reinforced steel-plastic composite pipe wire mesh testing device, a cylinder is fixedly installed at the upper end of the sliding frame, and an installation block is fixedly installed downward through the sliding frame at the extended end of the cylinder. An electromagnetic induction probe is provided at the bottom of the installation block.

[0015] The above-mentioned solution has the following beneficial effects:

[0016] This patent, through the setting of a mounting bracket, a second motor, a mounting ring, and a clamping assembly, allows the sliding block to drive the arc-shaped clamping plate to firmly clamp the pipe during use. The silicone pad helps to prevent damage to the pipe's surface. The second motor can drive the mounting ring to rotate the pipe, providing stable conditions for comprehensive inspection of the wire mesh in the circumference of the pipe. This is beneficial for discovering wire mesh defects in local areas around the pipe, avoiding blind spots in the inspection, and ensuring the integrity and accuracy of the inspection.

[0017] This patented technology incorporates a cylinder, a mounting block, and an electromagnetic induction probe. During use, the cylinder drives the mounting block to adjust the distance between the electromagnetic induction probe and the outer wall of the pipe. This ensures that the probe can accurately correspond to different layers of wire mesh inside the pipe, thereby guaranteeing the accuracy of detecting defects such as wire mesh position deviation and broken wires, and improving the reliability of the detection.

[0027] Reference Figure 1-4 This utility model discloses a testing device for steel wire mesh used in multi-reinforced steel-plastic composite pipes, comprising a testing platform 1. A mounting frame 15 is fixedly installed on the left end of the testing platform 1. A second motor 16 is fixedly installed on one side of the mounting frame 15. The output end of the second motor 16 passes through the mounting frame 15 and is connected to a mounting ring 20 via a coupling. A clamping assembly is provided inside the mounting ring 20, comprising a slider 17, an arc-shaped baffle 18, a screw 19, an arc-shaped clamping plate 21, and a silicone pad 22. Four openings 23 are symmetrically provided on the mounting ring 20, and sliders 17 are slidably installed in each of the four openings 23. An arc-shaped clamping plate 21 is fixedly pressed at the front end of each slider 17, and a silicone pad 22 is provided at the front end of each arc-shaped clamping plate 21. An arc-shaped baffle 18 is fixedly installed at the rear end of each slider 17. Four threaded holes 24 are symmetrically provided at the front end of the mounting ring 20. Each of the four threaded holes 24 is equipped with a screw 19, one end of which abuts against the slider 17. During use, the testing table 1 provides stable support for the overall structure. The motor 16 on the mounting frame 15 drives the mounting ring 20 to rotate through the coupling, which can drive the clamped pipe to rotate synchronously, laying the foundation for subsequent full-circumference testing. The clamping component inside the mounting ring 20, the slider 17 sliding in the four openings 23 can drive the front arc-shaped clamping plate 21 to flexibly adjust its position, and the silicone pad 22 at the front end of the arc-shaped clamping plate 21 can prevent damage to the pipe surface during clamping. By adjusting the screw 19 in the threaded hole 24 at the front end of the mounting ring 20 to press against the slider 17, the pipe can be firmly fixed to prevent displacement during testing. The arc-shaped baffle 18 at the rear end of the slider 17 can limit the sliding stroke of the slider 17, improving the safety and stability of the clamping component.

[0028] Two arc-shaped fixing frames 6 are symmetrically fixedly installed on the right end of the testing platform 1. Two fixing blocks 11 are symmetrically fixedly installed on one end of each arc-shaped fixing frame 6. A rotating rod 12 is rotatably installed between the two fixing blocks 11. An arc-shaped fixing plate 13 is fixedly installed in the middle of the rotating rod 12. The other end of the arc-shaped fixing plate 13 is threaded onto the other end of the arc-shaped fixing frame 6. Bolts 14 are threaded onto the other end of the arc-shaped fixing plate 13 and the arc-shaped fixing frame 6. In use, the two arc-shaped fixing frames 6 symmetrically installed on the testing platform 1 provide a stable support foundation for the right end of the pipeline. The two fixing blocks 11 at one end of the arc-shaped fixing frame 6, together with the rotating rod 12, allow the arc-shaped fixing plate 13 to rotate flexibly, making it convenient to put in or take out the pipeline. The arc-shaped fixing plate 13 is threaded onto the other end of the arc-shaped fixing frame 6 by bolts 14. Tightening the bolts 14 can prevent the pipeline from shifting during testing, ensuring the coaxiality and stability of the pipeline during testing, and providing reliable conditions for the accurate detection of the electromagnetic induction probe 7.

[0029] Support legs 3 are fixedly installed at the four corners of the bottom of the testing table 1. Two slots 4 are opened on both sides of the testing table 1. A slide rod 25 is fixedly installed in one slot 4, and a lead screw 5 is rotatably installed in the other slot 4. One end of the lead screw 5 passes through the testing table 1 and is connected to a motor 2 via a coupling. The motor 2 is fixedly installed at one end of the testing table 1. A sliding frame 10 is installed on the lead screw 5. The other end of the sliding frame 10 is slidably installed on the slide rod 25. A cylinder 9 is fixedly installed at the upper end of the sliding frame 10. An extension end of the cylinder 9 passes through the sliding frame 10 and is fixedly installed downwards on a mounting block 8. An electromagnetic induction probe 7 is installed at the bottom of the mounting block 8. During use, the support legs 3 at the four corners of the bottom of the testing table 1 provide stable support for the entire device, preventing the table from shaking and affecting accuracy during testing. The slots 4 on both sides of the testing table 1 are respectively equipped with the slide rod 25 and the rotatable lead screw 5. The motor 2 at one end of the test bench 1 is connected by a coupling. When the motor 2 drives the lead screw 5 to rotate, it can drive the sliding frame 10, which is installed in conjunction with it, to move smoothly along the slide rod 25, so as to realize the flexible detection of the electromagnetic induction probe 7 along the pipeline axis. The cylinder 9 at the upper end of the sliding frame 10 can push the mounting block 8 to move up and down, thereby adjusting the distance between the electromagnetic induction probe 7 at the bottom of the mounting block 8 and the pipeline, ensuring the positional accuracy of the probe during detection and improving the reliability of the detection.

[0030] Working Principle: When using a multi-reinforced steel-plastic composite pipe wire mesh testing device, firstly, the pipe to be tested is placed on the testing platform 1. The motor 16 on the mounting frame 15 is started, and its output end drives the mounting ring 20 to rotate via a coupling, pushing the sliding block 17 in the opening 23 to move. This causes the arc-shaped clamping plate 21 at the front end of the slider 17 to clamp the pipe. Simultaneously, the screw 19 in the threaded hole 24 on the mounting ring 20 is adjusted to abut against the slider 17 for fixation. Next, the other end of the pipe is placed into the arc-shaped fixing frame 6 on the right end of the testing platform 1. The rotating rod 12 between the fixing blocks 11 is rotated, causing the arc-shaped fixing plate 13 to engage with the pipe. Bolts 14 are then used to fix the arc-shaped fixing plate 13 to the arc-shaped fixing frame 6. Finally, the motor 16 on the mounting frame 15 is started, and its output end drives the mounting ring 20 to rotate via a coupling. The rotating mounting ring 20 drives the clamped pipe shaft, and then the motor 2 at one end of the test bench 1 is started, which drives the lead screw 5 in the slot 4 to rotate, so that the sliding frame 10 that is installed moves along the sliding rod 25 in the other slot 4. At the same time, the extension end of the cylinder 9 at the upper end of the sliding frame 10 pushes the mounting block 8 down, so that the electromagnetic induction probe 7 at the bottom of the mounting block 8 is close to the pipe. Finally, the electromagnetic induction probe 7 detects the wire mesh in the pipe. The motor 2 16 can drive the pipe to rotate, and the sliding frame 10 moves to achieve full-range detection of the pipe.
