Description

Technical Field

[0001] The utility model belongs to the technical field of pressure pipeline inspection, and particularly relates to a pressure vessel pressure pipeline inspection and detection device. Background Technique

[0002] A pressure vessel is a device used to store or contain gases or liquids, usually designed to withstand the internal pressure generated. A pressure pipeline is a pipeline system used in conjunction with a pressure vessel to transport gases, liquids or mixtures. To ensure the safe and reliable transmission process between the pressure vessel and the pressure pipeline, it is necessary to inspect and detect the pressure pipeline.

[0003] In the prior art, there is a pressure vessel pressure pipeline inspection and detection device with the patent publication number of CN218629459U. The above patent includes a base and a detection device. The detection device is fixedly installed on the top of the base. The ring is arranged at the top outside the detection device. A circular chute is opened at the bottom of the ring. Arc-shaped sliders are slidably connected to the four circumferences inside the circular chute. The bottom of the arc-shaped slider is fixedly installed with a folded column. The other end of the folded column is fixedly connected to the outside of the detection device. The internal gear ring is fixedly connected to the inside of the ring. A gear meshes with the inside of the internal gear ring. The device takes pictures of the details on the surfaces of the pressure vessel and the pressure pipeline through a high-definition monitoring device, so it is convenient for the staff to observe the actual situation of the surface defects of the pressure vessel and the pressure pipeline during the detection. However, there are still the following deficiencies in actual use: In practice, when the device is used, the pipeline to be tested is directly placed on the detection device, lacking fixing measures for the pipeline. During the inspection process, the pipeline is prone to shaking and even falling, posing a safety hazard. At the same time, the device drives the camera on the circular chute to perform circular motion through the cooperation of the internal gear ring and the gear. Since there will be relatively large friction and wear between the internal gear ring and the gear, the camera will vibrate when following the rotation, and the generated vibration will affect the shooting accuracy of the camera, thus affecting the detection data.

[0004] Therefore, a pressure vessel pressure pipeline inspection and detection device is needed to solve the problems in the prior art that the pipeline to be tested lacks fixing measures and is prone to shaking, and the camera vibrates when following the rotation, affecting the shooting and detection. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pressure vessel pressure pipeline inspection and detection device to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A pressure vessel pressure pipeline inspection and testing device, including a workbench, wherein a plurality of support columns are fixedly connected to the bottom of the workbench, a first rotating shaft is rotatably connected to the center position of the top of the workbench, a first synchronous pulley is fixedly connected to the outer wall of the first rotating shaft, a servo motor is installed at the bottom of the workbench, a second rotating shaft corresponding to the servo motor is rotatably connected to the top of the workbench, a second synchronous pulley is fixedly connected to the top of the second rotating shaft, a synchronous belt is installed on the outer walls of the first synchronous pulley and the second synchronous pulley, a frustum is fixedly connected to the top of the first rotating shaft, a lower fixed disk is fixedly connected to the top of the frustum, a convex-shaped frame is fixedly connected to the top of the workbench, a first electric telescopic rod is fixedly connected to the lower surface of the top of the convex-shaped frame, an upper fixed disk corresponding to the lower fixed disk is fixedly connected to the bottom of the first electric telescopic rod, two guide rods are fixedly connected to the top of the upper fixed disk, two second electric telescopic rods are fixedly connected to the top of the workbench, an installation groove is fixedly connected to the tops of the two second electric telescopic rods, rotating seats are installed on both inner walls of the installation groove, and a camera is fixedly connected between the two rotating seats.

[0007] It should be noted in the solution that shock pads are fixedly connected to the bottoms of the plurality of support columns.

[0008] Further, it is worth noting that the output end of the servo motor penetrates the workbench and is fixedly connected to the second rotating shaft.

[0009] Furthermore, it should be noted that the first synchronous pulley and the second synchronous pulley are at the same horizontal height.

[0010] As a preferred implementation manner, the lower fixed disk and the upper fixed disk are symmetrically arranged about the center, and both the lower fixed disk and the upper fixed disk adopt a multi-layer design, and a rotating bearing is installed on each layer.

[0011] As a preferred implementation manner, two through holes corresponding to the guide rods are opened at the top of the convex-shaped frame.

[0012] As a preferred implementation manner, the camera is installed directly behind the frustum.

[0013] Compared with the prior art, the pressure vessel pressure pipeline inspection and testing device provided by the present utility model has at least the following beneficial effects:

[0014] (1) By setting the first electric telescopic rod, the upper fixed disk and the lower fixed disk to cooperate, the inner wall of the pressure pipeline to be measured is inserted into the outer wall of the top of the lower fixed disk. The first electric telescopic rod is opened to drive the upper fixed disk to descend, so that the upper fixed disk and the lower fixed disk clamp and fix the pressure pipeline, avoiding the pipeline from shaking during the inspection. At the same time, both the upper fixed disk and the lower fixed disk adopt a multi-layer design, which can meet the pressure pipelines with different inner diameters, improving the applicability of the device.

[0015] (2) By setting the servo motor to drive the second synchronous wheel to rotate, under the action of the synchronous belt, the first synchronous wheel rotates accordingly, so that the frustum rotates. The rotation of the frustum drives the pressure pipeline between the upper fixed disk and the lower fixed disk to rotate. The camera takes high-definition images of the rotating pressure pipeline and transmits the data, which is convenient for detecting the detailed state of the surface of the pressure pipeline during work. By designing the rotation of the pressure pipeline instead of the rotation of the camera, the stability of the imaging effect is improved, and the influence of camera vibration on the detection data is avoided.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present invention with reference to the embodiments.

[0022] Please refer to Figures 1-4, the present utility model provides a pressure vessel and pressure pipeline inspection and testing device, which includes a workbench 1. A plurality of support columns 2 are fixedly connected to the bottom of the workbench 1. A first rotating shaft 3 is rotatably connected to the center position of the top of the workbench 1. A first synchronous pulley 4 is fixedly connected to the outer wall of the first rotating shaft 3. A servo motor 5 is installed at the bottom of the workbench 1. A second rotating shaft 6 corresponding to the servo motor 5 is rotatably connected to the top of the workbench 1. A second synchronous pulley 7 is fixedly connected to the top of the second rotating shaft 6. A synchronous belt 8 is installed on the outer walls of the first synchronous pulley 4 and the second synchronous pulley 7. A frustum 9 is fixedly connected to the top of the first rotating shaft 3. A lower fixing plate 10 is fixedly connected to the top of the frustum 9. A convex-shaped frame 11 is fixedly connected to the top of the workbench 1. A first electric telescopic rod 12 is fixedly connected to the lower surface of the top of the convex-shaped frame 11. A upper fixing plate 13 corresponding to the lower fixing plate 10 is fixedly connected to the bottom of the first electric telescopic rod 12. Two guide rods 14 are fixedly connected to the top of the upper fixing plate 13. Two second electric telescopic rods 15 are fixedly connected to the top of the workbench 1. An installation groove 16 is fixedly connected to the tops of the two second electric telescopic rods 15. Rotating seats 17 are installed on both inner walls of the installation groove 16. A camera 18 is fixedly connected between the two rotating seats 17.

[0023] Further, as shown in Figure 1 , Figure 2 and Figure 3 shown, it is specifically noted that shock pads are fixedly connected to the bottoms of the plurality of support columns 2, which play a role in buffering and shock absorption, ensuring that the workbench 1 is always in a stable state during the detection process, and providing a stable installation platform for the pressure pipeline and the camera 18.

[0024] Further, as shown in Figure 1 and Figure 2 shown, it is specifically noted that the output end of the servo motor 5 penetrates through the workbench 1 and is fixedly connected to the second rotating shaft 6, ensuring that the servo motor 5 can drive the second rotating shaft 6 to rotate smoothly, thereby providing a driving force for the frustum 9 to drive the pressure pipeline to rotate in a cycle.

[0025] Further, as shown in Figure 1 , Figure 2 and Figure 3 shown, it is specifically noted that the first synchronous pulley 4 and the second synchronous pulley 7 are at the same horizontal height, enabling the synchronous belt 8 to guide the first synchronous pulley 4, and the same horizontal height makes the follow-up movement of the first synchronous pulley 4 more stable.

[0026] According to the above working process, it can be known that by setting the first electric telescopic rod 12, the upper fixing plate 13 and the lower fixing plate 10 to cooperate, the inner wall of the pressure pipeline to be measured is inserted into the outer wall of the top of the lower fixing plate 10. The first electric telescopic rod 12 is opened to drive the upper fixing plate 13 to descend, so that the upper fixing plate 13 and the lower fixing plate 10 clamp and fix the pressure pipeline, preventing the pipeline from shaking during the inspection process.

[0027] Further, as shown in Figure 1 , Figure 2 and Figure 3 , it is worth specifically stating that the lower fixed disk 10 and the upper fixed disk 13 are centrosymmetrically arranged, and both the lower fixed disk 10 and the upper fixed disk 13 adopt a multi-layer design, and each layer is equipped with a rotating bearing. The rotating bearing ensures that the lower fixed disk 10 and the upper fixed disk 13 can rotate themselves while clamping and fixing the pressure pipeline. The multi-layer design can accommodate pressure pipelines with different inner diameters, improving the applicability of the device.

[0028] Further, as shown in Figure 1 , Figure 2 and Figure 3 , it is worth specifically stating that two through holes corresponding to the guide rods 14 are opened at the top of the convex frame 11. The through holes and the guide rods 14 cooperate to play a role in guiding and limiting the lifting of the upper fixed disk 13, making the lifting of the upper fixed disk 13 more stable.

[0029] Further, as shown in Figure 1 , Figure 3 and Figure 4 , it is worth specifically stating that the camera 18 is installed directly behind the frustum 9. The camera 18 is fixedly installed and will not shake, improving the accuracy of the picture data. At the same time, being installed directly behind the frustum 9 makes the acquisition of the picture of the outer wall of the pressure pipeline more sufficient.

[0030] This solution has the following working process: During actual use, insert the inner wall of the pressure pipeline to be tested into the outer wall of the top of the lower fixed disk 10, turn on the first electric telescopic rod 12 to drive the upper fixed disk 13 to descend, so that the upper fixed disk 13 and the lower fixed disk 10 clamp and fix the pressure pipeline. Then turn on the servo motor 5 to drive the second synchronous wheel 7 to rotate. Under the action of the synchronous belt 8, the first synchronous wheel 4 rotates accordingly, so that the frustum 9 rotates. The rotation of the frustum 9 drives the pressure pipeline between the upper fixed disk 13 and the lower fixed disk 10 to rotate. The camera 18 takes high-definition images of the rotating pressure pipeline and transmits the data. The staff receives the data through the processor and analyzes the detailed state of the surface of the pressure pipeline.

[0031] In summary: By setting the first electric telescopic rod 12 to cooperate with the upper fixed disk 13 and the lower fixed disk 10, the upper fixed disk 13 and the lower fixed disk 10 clamp and fix the pressure pipeline, avoiding the shaking of the pressure pipeline during the inspection process; by setting the rotation of the pressure pipeline instead of the rotation of the camera 18, the stability of the imaging effect is improved, and the vibration of the camera 18 is avoided from affecting the detection data.
