Description

Technical Field

[0001] This utility model relates to the field of pipeline measurement technology, specifically a pressure testing device for pressure pipelines. Background Technology

[0002] A pressure testing device for a pressure pipeline, disclosed in CN220120581 U, includes a testing frame and a pressure testing component. A gantry frame is bolted to the top of the testing frame, and the middle of the gantry frame is bolted to the surface of the pressure testing component. Racks are slidably connected to both sides inside the testing frame, with the teeth of the racks meshing with pinions. A rotating shaft is bolted to the axis of the pinions, and the surface of the rotating shaft is rotatably engaged with the interior of the testing frame. The top of the rotating shaft extends to the top of the testing frame and is bolted with a main bevel gear. Through the transmission of the structure, the clamping frames can be rotated. The two rotating clamping frames can provide three-point support and limitation for the pressure pipeline. Furthermore, it has strong adaptability to pressure pipelines and can be applied to pressure pipelines of various diameters.

[0003] Although the technical solution of this pressure pipeline pressure testing device has good adaptability and can be adapted to different diameter sizes, the defects it brings are also more obvious. For example, during the pipeline measurement process, it is not easy for personnel to clean the surface of the pipeline to be measured, which makes it inconvenient to obtain pipeline pressure measurement data. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pressure testing device for pressure pipelines, which solves the problem that it is difficult for personnel to clean the surface of the pipeline to be measured during the pipeline measurement process, resulting in inconvenience in obtaining pipeline pressure measurement data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure pipeline pressure testing device, comprising a movable plate, on both sides of the movable plate being fixedly installed with support rods, one side of the support rod being threadedly connected with a screw, the surface of the screw being threadedly connected with a constraint ring, one side of the surface of the constraint ring being hinged with a snap-fit ​​rod, the other side of the surface of the support rod being threadedly connected with a fixing bolt, and the surface of the fixing bolt being provided with a scraping component.

[0006] In one specific embodiment, the scraping assembly includes a positioning rod threaded to the thread on the other side of the fixing bolt surface, a flexible scraper fixedly installed on the middle of the back of the positioning rod, and a counterweight fixedly installed on the front of the positioning rod.

[0007] In one specific embodiment, both sides of the surface of the constraint ring are threaded with screws, and one end of the screws is rotatably connected to a flexible sheet.

[0008] In one specific embodiment, a threaded bolt is threaded to one side of the top surface of the snap-fit ​​rod, and a connecting block is threaded to the surface of the threaded bolt.

[0009] In one specific embodiment, a connecting rod is fixedly installed on one side of the top surface of the snap-fit ​​rod, and a hydraulic rod is fixedly installed in the middle of the top surface of the connecting rod.

[0010] In one specific embodiment, a pressure measuring head is fixedly installed at one end of the hydraulic rod, and a data display is electrically connected to the other side of the pressure measuring head.

[0011] In one specific embodiment, the bottom of the data display is fixedly connected to the other side of the top surface of the connecting rod, and omnidirectional wheels are fixedly installed at the four corners of the bottom of the movable plate.

[0012] Compared with the prior art, this utility model provides a pressure testing device for pressure pipelines, which has the following advantages:

[0013] In the technical solution disclosed in this utility model, by using the scraping component and the constraint ring, the pipe to be inspected is placed inside the constraint ring. Then, the personnel can rotate the pipe so that its surface is in contact with the surface of the flexible scraper. The flexible scraper can then clean the foreign objects adsorbed on the surface of the pipe, thereby facilitating the cleaning of foreign objects from the surface of the pipe.

[0014] The constraint ring of this invention has screws threaded through both sides of its surface. One end of each screw is rotatably connected to a flexible plate. A threaded bolt is threaded to one side of the top surface of the snap-fit ​​rod, and a connecting block is threaded to the surface of the threaded bolt. When personnel need to fix and position the pipe to be inspected, they can place the pipe inside the constraint ring and use the snap-fit ​​rod to constrain the pipe. Then, the screws drive the flexible plate downwards, and the flexible plate comes into contact with the surface of the pipe, thus fixing the pipe in place. This facilitates the positioning of the pipe during inspection. Attached Figure Description

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Figures 1-4 In one embodiment of this utility model, a pressure testing device for a pressure pipeline includes a movable plate 1. Support rods 2 are fixedly installed on both sides of the movable plate 1. A screw is threadedly connected to one side of the support rod 2. A constraint ring 3 is threadedly connected to the surface of the screw. A snap-fit ​​rod 4 is hinged to one side of the surface of the constraint ring 3. A fixing bolt is threadedly connected to the other side of the surface of the support rod 2. A scraping component 5 is provided on the surface of the fixing bolt.

[0023] The specific problem addressed by this embodiment is the difficulty for personnel to clean the surface of the pipe to be measured during pipeline measurement, leading to inconvenience in obtaining pipeline pressure measurement data. This invention utilizes the scraping component 5 and the constraint ring 3. When personnel place the pipe to be inspected inside the constraint ring 3, they can rotate the pipe, causing its surface to adhere to the surface of the flexible scraper 52. The flexible scraper 52 then cleans away any foreign matter adsorbed on the pipe surface, thus facilitating the cleaning of foreign objects from the pipe surface.

[0024] The scraping component 5 includes a positioning rod 51 threaded to the other side of the fixing bolt surface. A flexible scraper 52 is fixedly installed in the middle of the back of the positioning rod 51, and a counterweight 53 is fixedly installed on the front of the positioning rod 51. In this specific embodiment, screws 6 are threaded through both sides of the surface of the constraint ring 3. A flexible piece 7 is rotatably connected to one end of the screw 6. A threaded bolt is threaded to one side of the top surface of the snap-fit ​​rod 4, and a connecting block 8 is threaded to the surface of the threaded bolt. When personnel need to fix and position the pipe to be inspected, they can place the pipe inside the constraint ring 3 and use the snap-fit ​​rod 4 to constrain the pipe. Then, the screw 6 drives the flexible piece 7 to move downward, and the flexible piece 7 abuts against the surface of the pipe, thus fixing the pipe. This facilitates the positioning of the pipe during the inspection process.

[0025] In this specific embodiment, a connecting rod 9 is fixedly installed on one side of the top surface of the snap-fit ​​rod 4, and a hydraulic rod 10 is fixedly installed in the middle of the top surface of the connecting rod 9. A pressure measuring head 11 is fixedly installed at one end of the hydraulic rod 10. With the hydraulic rod 10, the pressure measuring head 11 and the data display 12, when personnel need to measure the pressure of the pipeline, they can turn on the power of the hydraulic rod 10, so that the hydraulic rod 10 drives the pressure measuring head 11 to apply pressure to one side of the pipe body. Subsequently, the data display 12 can display the detected pressure data. The other side of the pressure measuring head 11 is electrically connected to the data display 12. The bottom of the data display 12 is fixedly connected to the other side of the top surface of the connecting rod 9. Universal wheels 13 are fixedly installed at the four corners of the bottom of the moving plate 1. The universal wheels 13 facilitate the movement of the moving plate 1 by personnel.

[0026] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
