DETAILED DESCRIPTION

[0027] See also Figure 1-Figure 7 The present invention provides a technical solution: a pipeline support and hanger performance testing device, comprising a mounting frame 11, a plurality of support and hanger brackets 12 and a pipeline 13, and comprising support and hanger mounting mechanisms equal in number to the support and hanger brackets 12, wherein the support and hanger mounting mechanisms are used to install the support and hanger brackets 12;

[0028] A pressurizing mechanism, the pressurizing mechanism is used to apply a radial force to the pipeline 13;

[0029] The lower end of the mounting frame 11 is fixedly connected to a first mounting frame 14, the inner wall of the first mounting frame 14 is fixedly connected to a slide rail ring 15, the pressurizing mechanism is slidably connected to the slide rail ring 15, the pipeline 13 is coaxially arranged with the slide rail ring 15, and the pressurizing mechanism is connected to a locking mechanism, which is used to fix the pressurizing mechanism and the slide rail ring 15 to each other.

[0030] During operation, first install the supports and hangers 12 on the corresponding support and hanger installation mechanisms, and then fix the connecting pipe 13 together through multiple supports and hangers 12. When installing the pipe 13, pay attention to keeping the pipe 13 at the axial position of the slide rail ring 15. Then, according to the detection requirements, drive the pressure mechanism to slide on the slide rail ring 15 to change the direction of the radial force applied by the pressure mechanism to the pipe 13. After the adjustment is completed, fix the position of the pressure mechanism on the slide rail ring 15 through the locking mechanism. Finally, the pressure mechanism repeatedly applies radial force to the pipe 13 to detect the supports and hangers 12.

[0031] The present invention slides the pressurizing mechanism on the slide rail ring 15 so that the pressurizing mechanism can rotate 360 ​​degrees around the pipeline 13, thereby enabling the pressurizing mechanism to apply omnidirectional radial force to the pipeline 13, effectively simulating various stress phenomena of the pipeline 13, and performing more comprehensive detection of the support bracket 12.

[0032] As a further solution of the present invention, the support and hanger mounting mechanism includes a first slide plate 21, and guide rails 22 are provided at the front and rear ends of the first slide plate 21, and the guide rails 22 are vertically fixedly connected to the mounting frame 11, and the first slide plate 21 is vertically slidably connected to the guide rail 22, and the guide rail 22 is externally connected to a first locking mechanism, and the first locking mechanism is used to adjust and fix the position of the first slide plate 21 on the guide rail 22; the lower end of the first slide plate 21 is longitudinally slidably connected to a slide rail 23, and the slide rail 23 is externally connected to a second locking mechanism, and the second locking mechanism is used to adjust and fix the position of the slide rail 23 on the first slide plate 21; the lower end of the slide rail 23 is transversely slidably connected to a first slider 24, and the slide rail 23 is externally connected to a third locking mechanism, and the third locking mechanism is used to adjust and fix the position of the first slider 24 on the slide rail 23; the support and hanger 12 is vertically fixedly connected to the lower end of the first slider 24.

[0033] During operation, the support bracket 12 is first vertically fixedly connected to the corresponding lower end of the first slider 24, and then the position of the slide rail 23 on the first slider 21, the position of the slide rail 23 on the first slider 21 and the position of the first slider 24 on the slide rail 23 are adjusted respectively, thereby completing the regulation of the distribution spacing of the support bracket 12 and the regulation of the position of the pipeline 13, making the detection process more flexible.

[0034] As a further solution of the present invention, the pressurizing mechanism includes a second slider 31, which is slidably connected to the inner wall of the slide rail ring 15, and the end of the second slider 31 is fixedly connected to a fixing frame 32 along the radial direction of the slide rail ring 15, and a third slider 33 and a second slider 34 are respectively slidably connected to the fixing frame 32 along the outer side of the slide rail ring 15 to the axial direction, and a spring 35 is fixedly connected between the third slider 33 and the second slider 34, and the inner wall of one end of the fixing frame 32 close to the third slider 33 is rotatably connected to a first screw rod 38, the rod body of the first screw rod 38 passes through the third slider 33 and is threadedly connected to the third slider 33, and the end of the second slider 34 close to the axis of the slide rail ring 15 is fixedly connected to a connecting rod 36, and the connecting rod 36 passes through the fixing frame 32, and the end of the connecting rod 36 passing through the fixing frame 32 is fixedly connected to a pressing plate 37, and the pressing plate 37 is used to extrude the pipe 13, and the second slider 34 is connected to a control mechanism, and the control mechanism can control the pressing plate 37 to extrude the pipe 13 by supporting the second slider 34.

[0035] During operation, the position of the third slide plate 33 is adjusted by rotating the first screw rod 38, and the spacing between the third slide plate 33 and the second slide plate 34 (that is, the elastic force of the spring 35 at this time) is further adjusted when the pressure plate 37 squeezes the pipe 13, so as to adjust the size of the extrusion force of the spring 35 on the pipe 13 through the pressure plate 37 when the pressure plate 37 squeezes the pipe 13; after the adjustment is completed, the second slide plate 34 is repeatedly supported by the control mechanism. During this process, when the control mechanism supports the second slide plate 34, the elastic force of the spring 35 is supported by the control mechanism, and the pressure plate 37 will not squeeze the pipe 13. When the control mechanism does not support the second slide plate 34, the pressure plate 37 squeezes the pipe 13 under the action of the elastic force of the spring 35, and the size of the extrusion force is the size of the elastic force of the spring 35.

[0036] The present invention provides extrusion force through the spring 35, and the extrusion force is regulated by changing the compression amount of the spring 35, so that during the detection process, the extrusion force on the pipeline 13 is more stable, which effectively improves the detection quality.

[0037] As a further solution of the present invention, the locking mechanism includes a guide rod 41 fixedly connected to the upper and lower ends of the fixed frame 32 respectively, the end of the guide rod 41 completely fits the inner wall of the slide rail ring 15 and is slidably connected to the inner wall of the slide rail ring 15, the front and rear side walls of the guide rod 41 are fixedly connected with a clamping plate 42, the clamping plate 42 partially overlaps with the side wall of the slide rail ring 15, and the clamping plate 42 is located at the part that overlaps with the side wall of the slide rail ring 15 and is threadedly connected with a second screw 43.

[0038] During operation, after the position of the pressure mechanism is adjusted, the second screw 43 is tightened to squeeze the side wall of the slide rail ring 15 , thereby fixing the position of the guide rod 41 and further fixing the position of the fixing frame 32 .

[0039] The present invention limits the upper and lower ends of the fixing frame 32 by two guide rods 41 , so that the vibration generated during the detection process can be effectively buffered and limited by the two guide rods 41 , thereby ensuring the position accuracy of the fixing frame 32 during the detection process.

[0040] As a further solution of the present invention, the control mechanism includes a second mounting frame 51, which is located on one side of the first mounting frame 14 and fixedly connected to the lower end of the mounting frame 11. A sleeve 52 is fixedly connected inside the second mounting frame 51, and the sleeve 52 is coaxially arranged with the slide rail ring 15. A turntable 53 is rotatably connected to the inner wall of the sleeve 52. A trigger groove 54 is opened at one end of the turntable 53 close to the fixed frame 32. The trajectories of the two side walls of the trigger groove 54 are a group of eccentric circles. The trigger groove 54 is close to the outer wall of the turntable 53. The trajectory of one side wall is a circle with the axis of the turntable 53 as the center; the second slide plate 34 is fixedly connected to a slide rod 55 on the side close to the turntable 53, and the slide rod 55 is inserted into the trigger groove 54. The side wall of the trigger groove 54 close to the inner wall of the turntable 53 can be squeezed with the side wall of the slide rod 55. The turntable 53 is fixedly connected to a gear ring at one end away from the fixed frame 32, and the second mounting frame 51 is fixedly connected to a drive motor 57. The output shaft of the drive motor 57 is fixedly connected to a gear 58, and the gear 58 is meshed with the gear ring.

[0041] During operation, the driving motor 57 drives the gear ring to rotate through the gear 58, and the gear ring drives the turntable 53 to rotate. As the turntable 53 rotates, the slide bar 55 slides along the trigger slot 54 on the turntable 53. During this process, the inner wall of the trigger slot 54 switches between not contacting the slide bar 55 and squeezing the slide bar 55 toward the first slider 24. When the inner wall of the trigger slot 54 is not in contact with the slide bar 55, the pressure plate 37 squeezes the pipe 13. When the inner wall of the trigger slot 54 squeezes the slide bar 55 toward the first slider 24, the corresponding elastic force of the spring 35 on the second slider 31 is provided by the squeezing force of the inner wall of the trigger slot 54 on the slide bar 55, thereby completing the control of the pressure plate 37 repeatedly squeezing the pipe 13.

[0042] The present invention switches the main body that bears the elastic force of the second slider 31 through the trigger groove 54 with an eccentric circular contour. During the switching process, the slide rod 55 slides along the circular surface of the inner wall of the trigger groove 54, so that the process is relatively smooth. Further, when the pressure plate 37 squeezes the pipe 13, no momentum impact will be generated, resulting in an increase in the actual bearing force of the pipe 13, so that the equipment detection result is more accurate.

[0043] During actual use, the external force on the pipeline 13 is generally not a single torque, but more of an external force that causes the pipeline 13 to vibrate. The external force is mostly composed of two external forces in opposite directions acting alternately on the pipeline 13. Therefore, during conventional testing, the single squeezing force applied cannot effectively simulate the actual use of the pipeline 13.

[0044] As a further solution of the present invention, a group of pressurizing mechanisms are further arranged in the slide rail ring 15 , and the slide rods 55 of the pressurizing mechanisms are inserted into the triggering grooves 54 of the original pressurizing mechanisms.

[0045] During operation, the two groups of pressurizing mechanisms are adjusted so that they are symmetrically arranged; and then as the rotating disk 53 rotates, the pressing plates 37 of the two groups of pressurizing mechanisms squeeze the pipe 13 alternately.
