Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe detection, in particular to a PE pipe diameter detection mechanism. Background Art

[0002] PE pipes, also known as polyethylene plastic pipes, are relatively flexible compared to steel pipes. However, their disadvantages are that they are not as mechanically durable as steel pipes and are sensitive to chemicals. When PE pipes are in use, the thickness of the pipe wall becomes thinner due to corrosion or impact, which can cause pipe leakage. Therefore, it is very important to regularly detect changes in the inner diameter of the pipe for the maintenance of PE pipes.

[0003] The Chinese utility model patent with the authorization announcement number CN218034975U discloses a pipeline diameter detection device, including a lifting support seat and a measuring assembly. The lifting support seat includes an upper seat and a lower seat. A lifting drive mechanism for driving the upper seat to lift and lower is provided between the upper seat and the lower seat. Its working principle is as follows: the lifting support seat moves to the bottom of the measuring seat, and the upper seat is pushed upward by controlling the lifting drive mechanism, so that the support wheel on the upper seat cooperates with the corresponding circular track support, and at the same time, the arc plate is pushed upward. As the arc plate moves upward, the force on the top pressure head gradually decreases, and the top pressure head below gradually begins to be stressed. When the forces on the two top pressure heads are the same, the arc plate stops rising, and it is in the zero state at this time.

[0004] However, the above technical solution has the following problems: after inspecting one part of the pipeline, it is necessary to pull up the arc plate to disengage the support wheel from the grooved track of the side plate, and then move the two arc plates horizontally. After determining the next position of the pipeline, the lifting support seat is moved to the bottom of the arc plate again, and the previous operation is repeated to measure the upper and lower and left and right diameters of the pipeline here. When in use, it is necessary to frequently move the lifting support seat according to the position of the measuring component, which is cumbersome to operate and is not conducive to improving the detection efficiency.

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0042] See also Figure 1-Figure 4 The utility model provides a technical solution: a PE pipe diameter detection mechanism, comprising a workbench 1 and a rotating sleeve 12 arranged on the workbench 1, the rotating sleeve 12 is provided with a through groove for the PE pipe 22 to pass through, and the central axis of the through groove coincides with the central axis of the PE pipe 22, and a detection component for detecting the diameter of the PE pipe 22 is arranged on the inner wall of the through groove, and the detection component tests the surface smoothness of the PE pipe 22 by pressure, thereby detecting the diameter of the PE pipe 22; in this embodiment, the detection component includes two detection parts arranged oppositely, and the detection part includes: a connecting sleeve 14 with an opening at one end, which is arranged on the inner wall of the through groove of the rotating sleeve 12; a pressure-sensitive element 15 arranged inside the connecting sleeve 14; an elastic member 16 connected to the pressure-sensitive element 15 at one end; a movable rod 17 slidably arranged in the connecting sleeve 14, one end of the movable rod 17 is connected to the other end of the elastic member 16; a universal ball 18 connected to the other end of the movable rod 17, and the universal ball 18 fits the outer surface of the PE pipe 22;

[0043] The above technical solution can be used to detect the diameter change of the PE tube 22. The central axis of the rotating sleeve 12 and the central axis of the PE tube 22 are aligned and coincident. At this time, the universal ball 18 contacts the PE tube 22, and the distances between the two connecting sleeves 14 and the PE tube 22 are equal. The pressure of the elastic member 16 on the pressure-sensitive element 15 should be the same under normal circumstances. If the PE tube 22 is concave at this point, the elastic force of the elastic member 16 is reduced, so that the pressure-sensitive element 15 senses the pressure change and transmits the data to the panel through electrical signals. Conversely, when the PE tube 22 is convex at this point, the compressive elastic force of the elastic member 16 becomes larger, thereby realizing the diameter detection of the PE tube 22.

[0044] like Figure 1 or Figure 2As shown, the PE pipe diameter detection mechanism also includes: a clamping assembly for positioning the PE pipe 22; in this embodiment, the clamping assembly includes: a bracket 7 arranged at the upper end of the workbench 1, the bracket 7 is relatively provided with two clamping parts, and the clamping parts include: a No. 1 electric push rod 8 connected to the bracket 7 at the bottom; an arc plate 9 connected to the output end of the No. 1 electric push rod 8, and the arc plate 9 is provided with a groove that matches the PE pipe 22;

[0045] The above technical solution can be used to quickly position the PE tube 22. When in use, first place the PE tube 22 in the middle position of the two arc plates 9, start the No. 1 electric push rod 8 to drive the arc plates 9 closer to each other, so that the PE tube 22 is clamped by the arc plates 9.

[0046] like Figure 3 As shown, the PE pipe diameter detection mechanism also includes: a mounting plate 10 rotatably connected to the rotating sleeve 12; a side plate 11 disposed at the upper end of the mounting plate 10; a slide rail 13 disposed outside the rotating sleeve 12, and the slide rail 13 and the side plate 11 are rotatably matched, and a rotating assembly for driving the rotating sleeve 12 to rotate around the central axis of the PE pipe 22; in this embodiment, the PE pipe diameter detection mechanism also includes: a side plate 11 disposed at the upper end of the mounting plate 10; a slide rail 13 disposed outside the rotating sleeve 12, and the slide rail 13 and the side plate 11 are rotatably matched; the rotating assembly includes: a No. 1 motor 19 disposed at the upper end of the mounting plate 10; a gear 20 connected to the output shaft of the No. 1 motor 19; a rack 21 disposed outside the rotating sleeve 12, and the rack 21 is matched with the gear 20;

[0047] The above technical solution can realize 360-degree detection of the PE pipe 22. The No. 1 motor 19 is started to drive the gear 20 to rotate, and the gear 20 drives the rack 21 to engage, thereby driving the rotating sleeve 12 to rotate, and the universal ball 18 detects the PE pipe 22 at 360 degrees.

[0048] like Figure 2 As shown, the PE pipe diameter detection mechanism also includes: a second electric push rod 23 is arranged between the slider 3 and the mounting plate 10, and the second electric push rod 23 is used to adjust the height of the rotating sleeve 12 relative to the PE pipe 22;

[0049] The above technical solution can be used to calibrate the detection component. The No. 2 electric push rod 23 is started to drive the mounting plate 10 to rise and fall, ensuring that the central axis of the rotating sleeve 12 and the central axis of the PE tube 22 are aligned and coincident. At this time, the universal ball 18 contacts the PE tube 22, and the distances between the two connecting sleeves 14 and the PE tube 22 are equal. Under normal circumstances, the pressure of the elastic member 16 on the pressure-sensitive element 15 should be the same.

[0050] like Figure 2As shown, the PE pipe diameter detection mechanism also includes: a moving component for driving the rotating sleeve 12 to move along the central axis direction of the PE pipe 22; in this embodiment, the moving component includes: a slide groove 2 opened at the upper end of the workbench 1; a slider 3 slidably arranged in the slide groove 2, and the upper part of the slider 3 is connected to the mounting plate 10; a No. 2 motor 4 arranged on one side of the workbench 1; a screw rod 5 connected to the output shaft of the No. 2 motor 4 at one end, and the other end of the screw rod 5 penetrates into the slide groove 2 and cooperates with the screw rod groove 6 opened in the slider 3;

[0051] The above technical solution can realize rapid detection of PE pipe 22. When it is necessary to move to the position of the next PE pipe 22, start the No. 2 motor 4 to drive the screw rod 5 to rotate. The rotation of the screw rod 5 drives the slider 3 to slide in the slide groove 2. The slider 3 drives the mounting plate 10 connected to it to slide, thereby quickly switching to the next detection point, which is more convenient to use.

[0052] Working principle: When in use, first place the PE tube 22 in the middle of the two arc plates 9, start the No. 1 electric push rod 8 to drive the arc plates 9 to move closer to each other, so that the PE tube 22 is clamped by the arc plates 9, and then start the No. 2 electric push rod 23 to drive the mounting plate 10 to rise and fall, ensuring that the central axis of the rotating sleeve 12 and the central axis of the PE tube 22 are aligned and coincident. At this time, the universal ball 18 contacts the PE tube 22, and the spacing between the two connecting sleeves 14 and the PE tube 22 is equal. The pressure of the elastic member 16 on the pressure-sensitive element 15 should be the same under normal circumstances. Start the No. 1 motor 19 to drive the gear 20 to rotate, and the gear 20 drives the rack 21 to engage, thereby driving the rotating sleeve 1 2 rotates, the universal ball 18 detects the PE tube 22 at that place 360 ​​degrees. If the PE tube 22 is concave at that place, the elastic force of the elastic member 16 is reduced, so that the pressure sensitive element 15 senses the pressure change and transmits the data to the panel through an electrical signal. On the contrary, when the PE tube 22 is convex at that place, the pressure elastic force of the elastic member 16 becomes larger, thereby realizing the diameter detection of the PE tube 22. When it is necessary to move to the position of the next PE tube 22, the second motor 4 is started to drive the screw rod 5 to rotate. The rotation of the screw rod 5 drives the slider 3 to slide in the slide groove 2, and the slider 3 drives the mounting plate 10 connected thereto to slide, thereby quickly switching to the next detection point, which is more convenient to use.
