PE pipe has the characteristics of light weight, corrosion resistance, impact resistance, strong flexibility, etc., and can effectively resist the erosion of various chemical media. According to different production processes, PE pipe can be divided into high-density polyethylene (HDPE) and low-density polyethylene (LDPE) and other types.

[0036] A ratchet 26 is rotatably installed on the other side of the vertical plate 2, and the toggle tooth block 22 is used in conjunction with the ratchet 26.

A bevel gear A30 is fixedly installed at the axis of one end of the ratchet 26, thereby effectively driving the bevel gear A30 to perform unidirectional rotation adjustment.

[0037] When one end of the PE pipe is clamped between the two supporting rollers 9 and the two clamping rollers 11, and the other end of the PE pipe is located between the surfaces of the two balls 7, the electric telescopic rod 3 is started to extend to drive the pressing block 4 and the pressure sensor 5 to move downward, so that the pressing block 4 and the pressure sensor 5 perform a squeeze strength test on the other end of the PE pipe. At the same time, an electric control platform is installed on the vertical plate 2 to control the telescopic length of the electric telescopic rod 3, and the detection data of the pressure sensor 5 is transmitted to the electric control platform to obtain the result of the squeeze strength test;

[0038] The extension of the electric telescopic rod 3 drives the horizontal block 20, the vertical plate 21 and the toggle tooth block 22 to move downward. The downward movement of the toggle tooth block 22 is aligned and squeezed by the limit of the ratchet 26 and the ratchet 28, so that the toggle tooth block 22 compresses the spring A25 through the inverted T-shaped block A24, and then all the toggle tooth blocks 22 move to the bottom of the ratchet 26;

[0039] When the strength test is completed, the electric telescopic rod 3 retracts and moves upward, driving the horizontal block 20, the vertical plate 21 and the shifting tooth block 22 to move upward. At this time, the upward shifting tooth block 22 will shift the ratchet 26 to make the ratchet 26 rotate unidirectionally. The unidirectional rotation of the ratchet 26 will drive the bevel gear A30 to rotate 90 degrees in one direction.

[0040] The single lifting and rotating transmission component includes a vertical shaft 31 and a horizontal shaft 34 which are rotatably connected to the other side of the vertical plate 2. The top and bottom of the shaft A31 are respectively fixedly connected with a bevel gear B32 and a bevel gear C33. The bevel gear B32 is meshed with the bevel gear A30. One end of the horizontal shaft 34 is fixedly installed with a bevel gear D35 which is meshed with the bevel gear C33. A sprocket A36 is fixedly installed on one side of the horizontal shaft 34. A square shaft 37 is rotatably installed on the lower part of one side of the vertical plate 2. A sprocket B38 is fixedly installed on one end of the square shaft 37.

[0041] Two slide bars 41 are fixedly installed inside the groove base 1, and the moving seat 8 is slidably installed between the two slide bars 41. The surface of the square rotating shaft 37 is movably sleeved with an inner square moving tube 42, and one end of the surface of the inner square moving tube 42 is fixedly installed with a bearing 43, and the outer ring of the bearing 43 is fixedly installed with a connecting ring 44, and a connecting block 45 is fixedly installed between the bottom of the connecting ring 44 and the other end of the moving seat 8, so that the inner square moving tube 42 can be effectively rotated and adjusted.

[0042] When bevel gear A30 rotates, it will drive bevel gear B32 to rotate. The rotation of bevel gear B32 will drive the rotating shaft A31 and bevel gear C33 to rotate. The rotation of bevel gear C33 will drive bevel gear D35 to rotate the transverse shaft 34 and sprocket A36. The rotation of sprocket A36 will drive the square rotating shaft 37 to rotate through sprocket B38. The rotation of square rotating shaft 37 will effectively rotate the inner square moving tube 42 through bearing 43.

[0043] The rotation adjustment component includes an inner through groove 46 opened in the middle of the moving seat 8, two supporting rollers 9 are rotatably installed on the upper part of the inner through groove 46, and sprockets C47 are fixedly installed at the axis of the two supporting rollers 9, one end and one side of the upper part of the inner through groove 46 are respectively rotatably installed with sprockets D48 and sprocket E49, and a sprocket F50 is fixedly installed on the surface of the inner square moving tube 42, and a chain B51 is installed between the sprocket F50, the sprocket D48, the sprocket E49 and the two sprockets C47. The wrap angle between the chain B51 and the two sprockets C47 meets the rotation requirement of the sprocket C47, thereby effectively driving the two supporting rollers 9 to rotate and the clamped PE pipe to perform equal-angle rotation adjustment.

[0044] When the inner square moving tube 42 rotates, the sprocket F50 will be driven to rotate, and the sprocket F50 and the chain B51 will rotate. At the same time, the two sprockets C47 will be driven to rotate through the sprocket D48 and the sprocket E49. The rotation of the two sprockets C47 will drive the two supporting rollers 9 to rotate. The rotation of the two supporting rollers 9 will drive the PE pipe to rotate at equal angles through two rotatable clamping rollers 11 and two balls 7. A single transmission can perform a transmission rotation of ninety degrees, so that the extension and retraction of the electric telescopic rod 3 can drive the pressing block 4 and the pressure sensor 5 to perform extrusion strength detection at different points on the same position of the PE pipe.

[0045] Embodiment 3, on the basis of embodiment 2, the four-time lifting horizontal transmission component includes a disc 52 fixedly mounted on the other end of the transverse shaft 34, a forty-five-degree arc-shaped rack 53 is fixedly mounted on the circumferential surface of the disc 52, a transmission gear 54 is rotatably mounted on one end of the vertical plate 2, a sprocket G55 is fixedly mounted at the axis of one end of the transmission gear 54, one end of the horizontally movable transmission shaft 13 extends to the outside of one end of the groove base 1 and is fixedly connected to a sprocket H56, a chain C57 is installed between the sprocket H56 and the sprocket G55, thereby driving the horizontally movable transmission shaft 13 to rotate after the extrusion strength test of different points at the same position of the PE pipe is completed.

[0046] When the transverse axis 34 rotates 315 degrees and the transverse block 20 moves upward, it will continue to drive the transverse axis 34 to rotate. At this time, the rotation of the transverse axis 34 will drive the arc rack 53 to rotate through the disk 52. At this time, the rotation of the arc rack 53 will transmit the transmission gear 54 and drive the sprocket G55 to rotate. The rotation of the sprocket G55 will drive the horizontal moving transmission shaft 13 to rotate at the same angle through the chain C57 and the sprocket H56.

[0047] A spiral transmission groove 58 is provided on the surface of the horizontally movable transmission shaft 13, and the split reset component 12 includes a hollow box 59 fixedly installed in the middle of the bottom of the movable seat 8, and a T-shaped toggle pin 60 is movably inserted at the bottom of the hollow box 59, and the lower part of the T-shaped toggle pin 60 is inserted into the interior of the spiral transmission groove 58, and a spring B61 ​​is fixedly installed between the top of the T-shaped toggle pin 60 and the bottom of the movable seat 8, and a toggle plate 62 extending to the outside of one side of the hollow box 59 is fixedly installed on the upper part of the T-shaped toggle pin 60, so that the movable seat 8 can effectively move at an equal distance and drive the PE pipe to adjust the detection position, and at the same time, the movable seat 8 can effectively perform reset adjustment.

[0048] When the horizontal moving transmission shaft 13 rotates at equal angles, the T-shaped toggle pin 60 is toggled through the spiral transmission groove 58 to move horizontally, and the horizontal movement of the T-shaped toggle pin 60 drives the moving seat 8 to slide on the surfaces of the two slide bars 41. The horizontal movement of the moving seat 8 drives the clamped and fixed PE pipe to move horizontally at equal distances through the ball 7, so that different detection positions of the PE pipe can be moved to the bottom of the pressing block 4 and the pressure sensor 5.

[0049] When the movable seat 8 needs to be moved back and reset, the T-shaped push pin 60 is moved upward by the push plate 62 to compress the spring B61, and at the same time, the lower part of the T-shaped push pin 60 is moved out from the interior of the spiral transmission groove 58. At this time, the movable seat 8 can be moved back and reset on the surface of the two sliding rods 41, and then the push plate 62 is released, and the lower part of the T-shaped push pin 60 is inserted into the interior of the spiral transmission groove 58 again by the elastic restoring force of the spring B61.
