Detailed implementation manners

[0021] To make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the drawings and specific embodiments.

[0022] As shown in Figure 1 to Figure 4 , an embodiment of the present utility model provides a detection device for HDPE enhanced winding pipes, including a fixed base 1. A pressure detection component 2 is fixedly installed on the top of the fixed base 1, and an inner diameter detection component 3 is fixedly connected to one side of the pressure detection component 2 on the top of the fixed base 1; the fixed base 1 includes a base box 11. A placement groove 12 is opened on the top of the base box 11, and embedding grooves 13 are opened on both sides of the inner part of the placement groove 12 on the top of the base box 11. A fixing frame 14 is fixedly connected to the bottom end inside the base box 11. An electric telescopic rod 15 is fixedly connected inside the fixing frame 14. The top of the electric telescopic rod 15 is fixedly connected to a support frame 16. The support frame 16 is movably installed inside the base box 11, and clamping rods 17 are fixedly connected to both ends of the top of the base box 11.

[0023] Among them, the placement groove 12 is arc-shaped. By using the arc-shaped outer shape of the placement groove 12, when the HDPE enhanced winding pipe is placed inside the placement groove 12, due to the influence of the placement groove 12, the HDPE enhanced winding pipe stays inside the placement groove 12, avoiding the HDPE enhanced winding pipe from rolling on the surface of the base box 11, and thus facilitating the detection of the HDPE enhanced winding pipe.

[0024] Among them, the pressure detection component 2 includes a support frame 21 fixedly installed on the top of the base box 11. Lifting grooves 22 are formed on both sides inside the support frame 21. One end of the top of the support frame 21 is fixedly connected to a lifting motor 23. The bottom of the lifting motor 23 is fixedly connected to a rotating screw rod 24. The rotating screw rod 24 is rotatably installed inside the lifting groove 22 on one side of the support frame 21. A lifting frame 25 is threadedly connected to the outer surface of the rotating screw rod 24. The lifting frame 25 is slidably installed inside the lifting groove 22. The bottom of the lifting frame 25 is fixedly connected to a pressure sensor 26. The bottom of the pressure sensor 26 is fixedly connected to a pressing plate 27.

[0025] As shown in the attached Figure 4 figure, an activity groove 171 is formed at the upper end inside the clamping rod 17. A fixed shaft 172 is fixedly connected to the top of the activity groove 171. A rotating block 173 is rotatably installed on the outer surface of the fixed shaft 172. A pressing rod 175 is fixedly connected to one side of the rotating block 173 away from the clamping rod 17. A fixed ring 176 is fixedly connected to the upper end of the clamping rod 17. The rotating block 173 is movably sleeved on the outer surface of the fixed ring 176. A return spring 177 is movably sleeved on the outer surface of the fixed ring 176. The return spring 177 is located between the activity groove 171 and the rotating block 173. A cushion block 174 is fixedly connected above the rotating block 173 at the top of the clamping rod 17. Since one end of the rotating block 173 rotates around the fixed shaft 172, when the pressing rod 175 at one end of the rotating block 173 presses against the bottom of the HDPE enhanced winding pipe, the pressing rod 175 will cause the rotating block 173 to rotate on the outer surface of the fixed ring 176 under the force, and the return spring 177 is compressed. When the pressing rod 175 passes through the bottom end of the HDPE enhanced winding pipe, the return spring 177 exerts a reaction force to expand the pressing rod 175, and cooperates with the electric telescopic rod 15 to drive the support frame 16 and the clamping rod 17 to descend, so as to press the bottom end of the inner surface of the HDPE enhanced winding pipe, thereby keeping the HDPE enhanced winding pipe fixed on the top of the base box 11.

[0026] In addition, when the pressing rod 175 presses the bottom end of the inner wall of the HDPE enhanced winding pipe, the HDPE enhanced winding pipe will automatically roll inside the placement groove 12, so that the HDPE enhanced winding pipe is in the center position of the placement groove 12. When the electric telescopic rod 15 drives the clamping rod 17 to descend, the pressing rod 175 is in a slight pressing state on the HDPE enhanced winding pipe, avoiding deformation of the HDPE enhanced winding pipe caused by pressing and affecting the detection accuracy of the HDPE enhanced winding pipe.

[0027] As shown in the attached Figure 5As shown in the figure, the inner diameter detection component 3 includes a detection frame 31. Rotating wheels 32 are rotatably installed at both the upper and lower ends inside the detection frame 31. A transmission belt 33 is sleeved on the outer surface of the rotating wheel 32. An extrusion frame 34 is fixedly connected to the upper end inside the detection frame 31. A pressing frame 35 is movably sleeved inside the extrusion frame 34. A pressing roller 36 is arranged at the bottom of the pressing frame 35. A pressing spring 37 is sleeved on the outer surface of the pressing frame 35 between the extrusion frame 34 and the pressing roller 36. The pressing roller 36 is rotatably installed on the outer surface of the transmission belt 33. Using the reaction force of the pressing spring 37, the pressing roller 36 squeezes the transmission belt 33 on the surface of the rotating wheel 32, so that when the transmission belt 33 rotates on the surface of the rotating wheel 32, a certain damping will be generated to prevent the transmission belt 33 from rotating by itself due to the gravity of the fixed block 38 and the positioning rod 39.

[0028] Among them, the detection frame 31 is fixedly installed on one side of the top of the base box 11. A fixed block 38 is fixedly connected to the outer surface of one side of the transmission belt 33. A positioning rod 39 is fixedly connected to the side of the fixed block 38. A displacement ranging sensor 310 is fixedly connected to the bottom end inside the detection frame 31 below the fixed block 38. The height of the displacement ranging sensor 310 corresponds to the thickness of the HDPE enhanced winding pipe. According to the distance between the displacement ranging sensor 310 and the fixed block 38, the size of the inner diameter of the HDPE enhanced winding pipe is judged.

[0029] The working process of the present utility model is as follows:

[0030] During use, the HDPE enhanced winding pipe is placed inside the placement groove 12, and the electric telescopic rod 15 is started to drive the support frame 16 and the clamping rod 17 to rise. When the pressing rod 175 at one end of the rotating block 173 presses against the bottom of the HDPE enhanced winding pipe, the pressing rod 175 will cause the rotating block 173 to rotate on the outer surface of the fixed ring 176 under force, and the return spring 177 is compressed. When the pressing rod 175 passes through the bottom end of the HDPE enhanced winding pipe, the return spring 177 makes the pressing rod 175 unfold through the reaction force, and cooperates with the electric telescopic rod 15 to drive the support frame 16 and the clamping rod 17 to descend, thereby slightly pressing the bottom end of the inner surface of the HDPE enhanced winding pipe to keep the HDPE enhanced winding pipe fixed on the top of the base box 11.

[0031] While placing the HDPE enhanced winding pipe, one end of the HDPE enhanced winding pipe is sleeved on the outer surface of the positioning rod 39, and the positioning rod 39 is manually pushed to make the positioning rod 39 and the fixed block 38 rise, and the positioning rod 39 is attached to the top of the inner wall of the HDPE enhanced winding pipe, and the initial position of the distance between the displacement ranging sensor 310 and the fixed block 38 is detected.

[0032] Subsequently, start the lifting motor 23 to rotate the rotating screw 24, and control the lifting frame 25 to drive the pressing plate 27 to descend, pressing on the top of the HDPE enhanced winding pipe. Calculate the pressure received by the HDPE enhanced winding pipe through the pressure sensor 26. At the same time, detect the change in the inner diameter of the HDPE enhanced winding pipe according to the change in the position between the fixed block 38 and the displacement ranging sensor 310.
