Description

Technical Field

[0001] This utility model relates to the field of PE pipe production technology, specifically a pipe wall testing device for PE pipe production. Background Technology

[0002] PE pipes are plastic pipes. During the quality inspection of PE pipe production, in order to ensure the processing quality of PE pipes and avoid cracking during use due to uneven pipe wall thickness, it is necessary to inspect the pipe wall. Existing pipe wall inspection devices usually fix the pipe and use a handheld inspection device to rotate around the outside of the pipe to measure.

[0003] According to application number 202222936654.8, a pipe wall inspection device for PE pipe production is disclosed, relating to the field of PE pipe production technology. The device includes an inspection platform with a rotating cylinder above it. Through holes are formed on both sides of the rotating cylinder, and clamping rods are slidably connected inside the through holes. An arc-shaped clamping plate is fixedly connected to one end of the clamping rod inside the rotating cylinder. The side of the two arc-shaped clamping plates that is close to each other is a concave surface. A pull block is fixedly connected to the end of the clamping rod away from the arc-shaped clamping plate. A spring is fitted around the outside of the clamping rod, with one end fixedly connected to the pull block and the other end fixedly connected to the outer ring of the rotating cylinder. In this pipe wall inspection device for PE pipe production, the arc-shaped clamping plates, relying on the restoring force of the spring, can clamp and fix PE pipes of different sizes. The fixed pipes can be rotated by a motor, a first gear, a second gear, etc., allowing for the measurement of the pipe thickness at different locations without the need for a distance sensor.

[0026] By setting the fixing component 4, the PE pipe can be fixed more stably, preventing it from shifting during the inspection process.

[0028] After the PE pipe is fixed, the second motor 5 is started to drive the rotating shaft 3 to rotate, which in turn drives the fixing component 4 and the pipe to rotate, thereby detecting the thickness of the entire pipe wall.

[0029] Please see Figure 1 and Figure 4 The top of the base 1 is provided with a mounting plate 6, and the top of the mounting plate 6 is provided with a detection component 7. The detection component 7 includes a groove 701, a slide rail 702, a movable plate 703, a detection rod 704, a distance sensor 705, a top cover 706, and a screw 707.

[0033] In this invention, the working principle of the device is as follows:

[0034] In use, one end of the PE pipe to be tested is fitted onto the surface of the fixing component 4. By starting the first motor 406, the rotating disk 407 is driven to rotate, causing the connecting rod 405 to slide in the slide groove 408 and drive the movable rod 403 to move outward. At the same time, four movable rods 403 can be driven to move outward, so that the arc plate 404 abuts against the inner wall of the PE pipe and fixes the PE pipe. It can fix PE pipes of different sizes and can increase the stability of the fixation.

[0035] After the PE pipe is fixed on the fixing component 4, the height of the detection rod 704 can be adjusted according to the size of the PE pipe. By rotating the screw 707, the movable plate 703 can be driven to slide on the slide rail 702, and at the same time, the detection rod 704 can be driven to move up and down, so that the detection rod 704 is parallel to the side wall of the PE pipe. Then, by starting the cylinder 803, the mounting plate 6 can be pushed to move horizontally, and at the same time, the detection rod 704 and the distance sensor 705 can be moved horizontally, so that the concave position of one end of the detection rod 704 can be inserted into the side wall of the PE pipe. Then, the wall thickness of the pipe is detected by the distance sensor 705. During the detection, by starting the second motor 5 to drive the rotating shaft 3 to rotate, the fixing component 4 and the pipe can be rotated, thereby detecting the thickness of the entire pipe wall.
