Description
TECHNICAL FIELD
[0001] The utility model relates to pipeline production detection technical field especially, relate to a kind of PE pipeline wall thickness uniformity detection production equipment. BACKGROUND
[0002] Polyethylene (PE) pipeline has been widely used in municipal water supply and drainage, gas transmission, industrial fluid transmission and other fields due to its excellent corrosion resistance, flexibility and long service life. The uniformity of pipeline wall thickness is a key indicator to ensure its pressure-bearing capacity, sealing performance and service life, and is directly related to the safe operation of the pipeline system. Currently, online detection equipment is widely used in the industry to monitor the wall thickness of PE pipeline after extrusion molding. Sensor arrays or rotary thickness measuring devices are used to take multiple samples of the outer diameter of the pipe, and a data processing system is used to determine whether the wall thickness uniformity meets the standards.
[0003] However, the existing detection equipment has the following problems in actual application: traditional limiting mechanisms often use fixed ring supports or rigid clasp structures, which require the entire pipeline to be inserted into the limiting ring during installation, making it difficult to disassemble during equipment debugging and maintenance. In particular, when the clasp mechanism deforms due to long-term use, it may become stuck, severely affecting detection efficiency. The existing thickness measuring devices often use rigid contact probes or fixed-diameter measuring rings, which cannot adapt to diameter fluctuations of different specifications of pipes. When the pipe expands or contracts due to heat or has slight ovality, measurement errors may occur. Rigid contact may also cause scratches on the pipe surface. The existing elastic buffer structure also has problems such as rebound lag and stress relaxation, resulting in insufficient stability of measurement data. Therefore, we provide a PE pipeline wall thickness uniformity detection production equipment. UTILITY MODEL CONTENTS

[0027] Embodiment 1
[0028] As Figures 1-4 Indicated, the utility model provides a kind of technical scheme: a kind of PE pipeline wall thickness uniformity detection production equipment, comprising: limiting mechanism 1, limiting mechanism 1 includes limiting half ring 11, limiting half ring 11 is provided with butt joint hinge 12 in one end, the inside of two limiting half rings 11 is provided with internal protective ring 13, and the end, away from butt joint hinge 12 of limiting half ring 11 is provided with fixed mechanism 2;
[0029] The fixing mechanism 2 includes a mounting base plate 21, a mounting frame 22 is provided in each of the two mounting base plates 21, a snap-fit base 23 is provided in each of the two mounting base plates 21, a snap-fit device 24 is provided on each of the two snap-fit bases 23, a disassembly device 25 is provided on one of the mounting base plates 21, and a fixing pin 26 is provided on the other mounting base plate 21.
[0030] The two ends of the hinge 12 on the same side are respectively connected to one end of the two limiting half rings 11. The outer surface of the inner protective ring 13 is nested in the ring formed by the two limiting half rings 11. The two mounting plates 21 are respectively installed at the ends of the two limiting half rings 11 away from the hinge 12. The mounting base 22 is inserted through the mounting plate 21 and installed on the limiting half ring 11. The outer surface of the snap-on base 23 is nested in the mounting plate 21 and is installed using the disassembly tool 25 and the fixing pin 26 respectively. The snap-on base 23 installed by the disassembly tool 25 can be disassembled from the mounting plate 21. The snap-on devices 24 on the two snap-on bases 23 can be hinged and fixed to each other.
[0031] In this embodiment, when the operator uses this testing device to test the uniform wall thickness of the pipeline, one end of the limiting half-ring 11 is connected to the discharge port of the production device. Then, the two limiting half-rings 11 are flipped and spliced into a complete ring through the connecting hinge 12. The ring is then fixed by using the snap-fit base 23 and snap-fit device 24 fixed on the mounting plate 21 at the end of the limiting half-ring 11 away from the connecting hinge 12. The disassembly device 25 can prevent the snap-fit device 24 from getting stuck and becoming impossible to disassemble during actual use, thereby improving its practicality in actual use.
[0032] Example 2
[0033] like Figures 1-4 As shown, the inner protective ring 13 is provided with an embedded mechanism 3, which includes a silicone ring 31, an inner insert 32 in the silicone ring 31, and a variable elastic rod 33 in the inner insert 32.
[0034] The outer surface of the silicone ring 31 is nested in the inner protective ring 13, the inner surface of the silicone ring 31 is nested in the inner sleeve 32, and the outer surface of the variable elastic rod 33 is nested in the inner sleeve 32 with reserved space for pipe embedding.
[0035] In this embodiment, in order to further improve its practicality in actual use, the corresponding embedding mechanism 3 is arranged in the internal protective ring 13 in the limiting half ring 11. The staff can measure the wall thickness by nesting the outer surface of the silica gel ring 31 in the internal protective ring 13, then nesting the outer surface of the internal embedding cylinder 32 in the silica gel ring 31, and nesting the outer surface of the variable elastic rod 33 in the internal embedding cylinder 32, so that its practicality in actual use is further improved.
[0036] Working principle:
[0037] As shown in Figures 1-4 When using the detection device to detect the uniform wall thickness of the pipeline, the staff first connects one end of the limiting half ring 11 with the discharge port of the production device to ensure that the limiting half ring 11 is stably connected with the discharge port. Then, the staff adjusts the two limiting half rings 11 by the butt hinge 12 to make them into a complete ring structure. The design of this structure ensures the stability of the device and the good fit of the pipeline.
[0038] In order to ensure the reliable fixation of the limiting half ring 11, the staff will use the buckle base 23 and the buckle 24 on the mounting seat plate 21 to fix it at the end of the limiting half ring 11 away from the butt hinge 12, and complete the hinged fixation. This design makes the device firmly clamp the pipeline, ensuring the stability and accuracy of the pipeline during detection.
[0039] In order to solve the problem that the buckle 24 may be stuck during use and cannot be disassembled, the device is equipped with a disassembler 25. The design of the disassembler 25 can effectively avoid the sticking of the buckle 24, ensuring that the staff can disassemble the device smoothly during use, improving the convenience and maintainability of the equipment.
[0040] On the basis of improving the convenience and reliability of the device, in order to further improve its practicality in actual use, the internal protective ring 13 is arranged in the limiting half ring 11, and the embedding mechanism 3 is integrated in the internal protective ring 13. The staff can nest the outer surface of the silica gel ring 31 in the internal protective ring 13 to ensure the accuracy and stability of the protective ring for pipeline wall thickness measurement. Then, the outer surface of the internal embedding cylinder 32 is nested in the silica gel ring 31, and the outer surface of the variable elastic rod 33 is nested in the internal embedding cylinder 32, so that the accurate control of pipeline insertion measurement can be realized. Through this structure design, the device can uniformly apply pressure on the pipeline, so that the detection process of the pipeline wall thickness is more accurate and will not cause errors due to uneven contact.
[0041] The design of such an embedded mechanism 3 not only ensures the accuracy of the measurement, but also effectively avoids the interference of external factors on the detection result, thereby improving the stability and durability of the detection device. The variable elastic rod 33 can adjust the pressure according to the shape and size of different pipelines, further enhancing the adaptability of the device.

Accordingly, any and all such alternatives, modifications, equivalents, improvements and the like are intended to be encompassed by the present application.
