Description

Technical Field

[0001] This invention relates to a PVC reinforced hose bending test apparatus and method, belonging to the field of PVC reinforced hose testing technology. Background Technology

[0002] PVC reinforced hoses are widely used in water supply and drainage, chemical transportation, hydraulic pipelines for construction machinery, and agricultural irrigation due to their advantages such as corrosion resistance, flexibility, low cost, and strong pressure resistance. In practical use, PVC reinforced hoses must frequently withstand bending, torsion, and reciprocating bending forces. Especially in mobile equipment and complex pipeline layout scenarios, the hose's bending fatigue performance, adaptability to multi-angle bending, and resistance to fracture and deformation directly determine its service life and safety.

[0003] Conventional experimental setups often use simple clamps to hold the flexible tubing, which are prone to loosening and slippage during bending, making it impossible to guarantee the stability of the bending position and stress state. This results in large deviations in experimental data. Most devices can only perform bending tests in a single direction and at a fixed angle, and cannot simulate the complex stress scenarios of multi-angle, fan-shaped, and reciprocating bending in actual working conditions. The test results have a low degree of matching with actual performance. The number of bends and the bending angle need to be recorded and adjusted manually, which is cumbersome, inefficient, and makes it difficult to guarantee data accuracy. Summary of the Invention

[0010] Furthermore, the lateral pushing component includes a telescopic cylinder fixed on the arc-shaped sliding plate. The output end of the telescopic cylinder is connected to a connecting vertical plate via a U-shaped block. The end of the connecting vertical plate is fixed with a horizontal plate that can move through the arc-shaped sliding groove. The top of the horizontal plate is connected and fixed to the bending guide component.

[0011] Furthermore, the bending guide assembly includes a hollow semi-circular shell fixedly connected to a horizontal plate. A central positioning wheel is provided at the center of the hollow semi-circular shell, and the central positioning wheel is fixed inside the hollow semi-circular shell by a support member.

[0012] Furthermore, three guide rollers are provided inside the hollow semi-circular shell near the outer side, and three adjustment grooves are provided at the bottom of the hollow semi-circular shell.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-7This invention provides a technical solution for a PVC reinforced hose bending test device, including a fixed support base 1, a bidirectional adjustment component 2 mounted on the fixed support base 1, and an intelligent control sensor mounted on the bidirectional adjustment component 2. A PVC hose positioning component 3 is rotatably mounted on the bidirectional adjustment component 2. An auxiliary clamping component 43 connected to the bidirectional adjustment component 2 is disposed between the PVC hose positioning components 3. The PVC hose positioning component 3 is used to clamp the PVC reinforced hose body 4. Through the action of the PVC hose positioning component 3, one end of the PVC reinforced hose body 4 is clamped and positioned, and the other end of the PVC reinforced hose body 4 passes through a bending guide component 8, so that the PVC reinforced hose body 4 bends, thereby achieving hose positioning. The auxiliary clamping component 43 can cooperate with the PVC hose positioning component 3 to improve the clamping stability through clamping forces in different directions. To prevent rotation of the PVC reinforced hose body 4 during bending, the bidirectional adjustment component 2 drives the PVC hose positioning component 3 to reciprocate, enabling a lateral bending test of the PVC reinforced hose body 4. An intelligent control sensor detects the number of movements, counting the number of bends. A support plate 5 is installed on one side of the bidirectional adjustment component 2 on the fixed support base 1. An annular bending component 6 is installed on the support plate 5, and an intelligent angle sensor is installed on the annular bending component 6. A lateral pushing component 7 is installed on the annular bending component 6, and a bending guide component 8 is connected to the end of the lateral pushing component 7. One end of the PVC reinforced hose body 4 passes through the bending guide component 8. Using the annular bending component 6 in conjunction with the intelligent angle sensor, the longitudinal bending detection of the PVC reinforced hose body 4 is achieved, thereby testing the multi-angle bending performance of the PVC reinforced hose body 4.

[0021] See Figure 2 The bidirectional adjustment assembly 2 includes a lower transverse support slide rail 9 and an upper longitudinal support slide rail 10. A sliding connecting plate 11 connected to the upper longitudinal support slide rail 10 is slidably mounted on the lower transverse support slide rail 9. A sliding mounting plate 12 is mounted on the upper longitudinal support slide rail 10. Motors 13 are mounted on both the sliding connecting plate 11 and the sliding mounting plate 12. An intelligent control sensor is electrically connected to the motors 13 and controls the motors 13. A rack 14 is installed inside both the lower transverse support slide rail 9 and the upper longitudinal support slide rail 10. A gear meshing with the rack 14 is connected to the output end of the motor 13. Guide protrusions 15 are provided on both sides of the lower transverse support slide rail 9. Guide pulleys 16 matching the guide protrusions 15 are rotatably mounted on both sides of the bottom of the sliding connecting plate 11. The corresponding motor 13 is controlled by the set intelligent control sensor. The lower transverse support slide rail 9 and the upper longitudinal support slide rail 10 are driven by the corresponding rack 14 and gear to realize the transverse movement of the upper longitudinal support slide rail 10 and the longitudinal movement of the sliding mounting plate 12, so as to realize the bending detection of the PVC reinforced hose body 4.

[0022] See Figure 3 The PVC hose positioning assembly 3 includes a telescopic hydraulic cylinder 17 fixed on a sliding mounting plate 12. The output end of the telescopic hydraulic cylinder 17 is connected to an upper housing 18. A bending plate 19 is rotatably connected to the top of the upper housing 18, and a clamping plate 20 is rotatably connected to the top of the bending plate 19. A connecting block 21 is fixed to the outside of the clamping plate 20, and an electric telescopic rod 22 is rotatably connected between the upper housing 18 and the connecting block 21. By adjusting the overall height through the telescopic hydraulic cylinder 17, the electric telescopic rod 22 drives the connecting block 21 to bend, thereby achieving the clamping and positioning of the PVC reinforced hose body 4.

[0023] See Figure 4-5 The annular bending assembly 6 includes a connecting seat 23 fixed on a support pad 5. One end of the connecting seat 23 is fixed with an arc-shaped support plate 24. An arc-shaped sliding groove 25 is provided at the center of the arc-shaped support plate 24, and inner positioning grooves 26 are provided on both sides of the inner wall of the arc-shaped sliding groove 25. An arc-shaped sliding plate 27 is slidably provided on the outer wall of the arc-shaped sliding groove 25. A sliding guide block 28 extending into the arc-shaped sliding groove 25 is integrally connected to the arc-shaped sliding plate 27. Guide protrusions matching the inner positioning grooves 26 are provided on both sides of the sliding guide block 28. An arc-shaped rack 31 is integrally connected to one side of the arc-shaped support plate 24. A forward and reverse motor 29 connected to the intelligent angle sensor is fixedly installed on one side of the arc-shaped sliding plate 27. The output end of the forward and reverse motor 29 is connected to a rolling gear 30 that meshes with the arc-shaped rack 31. The forward and reverse motor 29 drives the rolling gear 30 to rotate on the arc rack 31, which in turn drives the arc slide plate 27 to produce arc motion in cooperation with the arc sliding groove 25 and the sliding guide block 28. The guide protrusion cooperates with the inner positioning groove 26 to achieve the guiding and positioning effect, thereby driving the bending guide component 8 to produce an angle deflection. The size of the angle deflection can be detected by the intelligent angle sensor.

[0024] See Figure 6 The lateral pushing component 7 includes a telescopic cylinder 32 fixed to the arc-shaped sliding plate 27. The output end of the telescopic cylinder 32 is connected to a connecting vertical plate 34 via a U-shaped block 33. A horizontal plate 35, which can move through the arc-shaped sliding groove 25, is fixed to the end of the connecting vertical plate 34. The top of the horizontal plate 35 is connected and fixed to the bending guide component 8. By cooperating with the U-shaped block 33 and the connecting vertical plate 34, the telescopic cylinder 32 drives the horizontal plate 35 to move, thereby adjusting the bending guide component 8.

[0025] See Figure 7The bending guide assembly 8 includes a hollow semi-circular shell 36 fixedly connected to a horizontal plate 35. A center positioning wheel 37 is located at the center of the hollow semi-circular shell 36, and the center positioning wheel 37 is fixed inside the hollow semi-circular shell 36 by a support member 38. Three guide rollers 39 are located near the outer side of the hollow semi-circular shell 36. Three adjustment grooves 40 are located at the bottom of the hollow semi-circular shell 36. A connecting shaft 41, penetrating the adjustment groove 40, is located at the bottom of each guide roller 39, and a limiting nut 42 is threaded onto the bottom end of the connecting shaft 41. Through the action of the center positioning wheel 37 and the guide rollers 39, the bending and positioning of the PVC reinforced hose body 4 can be achieved. By loosening the limiting nut 42, the connecting shaft 41 and the guide rollers 39 can be adjusted on the adjustment grooves 40, thereby adapting to different specifications of PVC reinforced hose bodies 4.

[0026] See Figure 8 The auxiliary clamping component 43 includes a telescopic sleeve plate 44 fixed on the sliding mounting plate 12. A connecting plate 45 is fixedly connected to the top of the telescopic sleeve plate 44. A side positioning plate 46 is integrally connected to the connecting plate 45. An eccentric turntable 47 is rotatably mounted on one side of the side positioning plate 46. A drive motor connected to the eccentric turntable 47 is mounted on the other side of the side positioning plate 46. A clamping plate 49 is rotatably connected to the eccentric turntable 47 via an arc-shaped plate 48. A guide post 51 is fixed on the side positioning plate 46 and moves through the clamping plate 49. Arc-shaped elastic pads 50 are fixedly connected to the inner side of the clamping plate 49. The forward and reverse rotation of the drive motor drives the eccentric turntable 47 to rotate, causing the arc-shaped plate 48 to drive the clamping plate 49 to move synchronously closer or further away under the guidance of the guide post 51. This, in conjunction with the arc-shaped elastic pads 50, enables the PVC reinforced hose body 4 to be oriented, avoiding rotation problems.

[0027] See Figure 9 A method for testing the bending of PVC reinforced hoses, specifically including the following steps: S1. Before use, prepare a PVC reinforced hose body of appropriate length 4; S2. Insert the PVC reinforced hose body 4 into the bending guide assembly 8, and position one end of the PVC reinforced hose body 4 using the PVC hose positioning assembly 3. S3. Using the bidirectional adjustment component 2 in conjunction with the bending guide component 8, the bending test of the PVC reinforced hose body 4 is realized during the movement of the bidirectional adjustment component 2. The number of reciprocating movements of the bidirectional adjustment component 2 is detected by the intelligent control sensor, thereby obtaining the number of bends of the PVC reinforced hose body 4. S4. By utilizing the function of the annular bending component 6, the PVC reinforced hose body 4 can bend upward in a fan shape. The bending angle can be detected by the intelligent angle sensor. S5. The lateral pushing component 7 pushes the bending guide component 8 and adjusts the bending guide component 8.

[0028] In use, the PVC hose positioning component 3 clamps and positions one end of the PVC reinforced hose body 4, while the other end passes through the bending guide component 8, causing the PVC reinforced hose body 4 to bend and thus positioning the hose. The bidirectional adjustment component 2 drives the PVC hose positioning component 3 to reciprocate, enabling a lateral bending test of the PVC reinforced hose body 4. An intelligent control sensor detects the number of movements, counting the number of lateral bends. The annular bending component 6, in conjunction with an intelligent angle sensor, detects the longitudinal bending of the PVC reinforced hose body 4, thereby testing the multi-angle and torsional bending performance of the PVC reinforced hose body 4. This invention effectively positions the PVC reinforced hose body 4, preventing loosening during bending, and intelligently detects the number of bends. It also enables bending tests at different angles on the same PVC reinforced hose body 4, improving the bending detection effect and testing the multi-angle and torsional bending performance of the PVC reinforced hose body 4.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
