Description

Technical Field

[0001] This utility model relates to the field of non-destructive testing of pressure pipelines, and in particular to a non-destructive testing device for pressure pipelines. Background Technology

[0002] Pressure pipelines are pipes that can withstand internal or external pressure and are used to transport media such as liquids, gases, or steam. In industrial applications, pressure pipelines are widely used in fields such as oil, natural gas, and water supply, undertaking the task of transporting high-pressure liquids or gases.

[0003] To ensure the safety, reliability, and long-term stable operation of existing pressure pipelines, non-destructive testing (NDT) equipment is required for pipeline inspection. However, some equipment, after fixing the pipeline in place, uses an X-ray emitter and receiver to inspect it. Because the emitter is fixed, the pipeline needs to be rotated for complete inspection. The pipeline itself is heavy, and rotating it requires considerable effort from the operators, significantly increasing their workload and reducing the efficiency of pipeline inspection. Utility Model Content

[0004] The main objective of this invention is to provide a non-destructive testing device for pressure pipelines, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A non-destructive testing device for pressure pipelines includes a mounting frame with two sets of clamps symmetrically distributed about the central axis of the frame. Each clamp has a mounting groove, and movable grooves are formed on both sides of the mounting groove. A sliding shaft is slidably disposed within each movable groove, and a detector is fixedly connected to the sliding shaft. One end of the detector extends into the mounting groove, with its X-ray end positioned within the groove. Connecting shafts are fixedly connected to both sides of each clamp, and a connecting plate is fixedly connected to one end of each connecting shaft. A moving component is provided on the mounting frame to move the clamps via the connecting plate.

[0006] As a further embodiment of this utility model, the movable component includes two sets of movable slots formed on the mounting frame. The two sets of movable slots are symmetrically distributed about the central axis of the mounting frame. A movable plate is slidably disposed in the movable slot, and one side of the movable plate is fixedly connected to one end of the connecting plate.

[0007] As a further embodiment of this utility model, the movable component also includes a motor disposed on one side of the mounting frame, and screws are rotatably connected in both sets of movable slots, with one set of screws being fixedly connected to the output end of the motor.

[0008] As a further embodiment of this utility model, one end of each of the two sets of screws extends through to one side of the mounting frame, and a sprocket is fixedly connected to each of the two sets of screws, with a chain meshing with each of the two sets of sprockets.

[0009] As a further embodiment of this utility model, a protective shell is snapped onto one side of the mounting bracket, and the protective shell covers the outside of the sprocket and the chain.

[0010] As a further embodiment of this utility model, both sets of clamps are provided with a plurality of rotating grooves, which are distributed in an array at equal intervals, and a rotating shaft is fixedly connected in the rotating groove.

[0011] As a further embodiment of this utility model, a pulley is fixedly connected to the rotating shaft, and a baffle is fixedly connected to one end of the rotating shaft.

[0012] The beneficial effects of this utility model are as follows: The movable components on the mounting bracket, along with the connecting plate and connecting shaft, drive two sets of clamps to move. These clamps hold the pipe in place. Once the pipe is fixed, the operator moves the movable inspection device along the outer wall of the clamps. The two inspection devices slide through the provided mounting grooves, while the sliding shaft slides within the movable grooves. The sliding shaft restricts the movement of the inspection device, ensuring it moves along the outer wall of the clamps. This allows for non-destructive testing of the pipe using the movable inspection device. The movable inspection device facilitates inspection around the pipe, eliminating the need for operators to rotate the pipe during inspection. This significantly reduces the physical exertion of the inspectors, decreases their workload, and increases the efficiency of pipe inspection, thus saving inspection time. The rotating groove connects the rotating shaft and pulley to the mounting frame, while the baffle protects the rotating shaft and pulley. The rotating shaft facilitates the sliding of the pulley. After clamping the pipe, the sliding pulley allows for easy fine-tuning of the pipe's position, increasing the ease of use and practicality of the equipment. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-7 As shown, a pressure pipeline non-destructive testing device includes a mounting frame 1, on which two sets of clamps 2 are provided. The two sets of clamps 2 are symmetrically distributed about the central axis of the mounting frame 1. The clamps 2 are provided with mounting grooves 3. Movable grooves 4 are provided on both sides of the mounting grooves 3. A sliding shaft 5 is slidably arranged in the movable grooves 4. A detector 6 is fixedly connected to the sliding shaft 5. One end of the detector 6 extends into the mounting groove 3, and the X-ray end of the detector 6 is located in the mounting groove 3.

[0017] In this embodiment, both sides of the clamp 2 are fixedly connected to a connecting shaft 10, and one end of the connecting shaft 10 is fixedly connected to a connecting plate 9; a moving component is provided on the mounting frame 1, which is used to drive the clamp 2 to move through the connecting plate 9.

[0018] When the pipe needs to be clamped, the moving component on the mounting bracket 1, in conjunction with the connecting plate 9 and the connecting shaft 10, drives the two sets of clamps 2 to move. The two sets of clamps 2 clamp the pipe. After the pipe is fixed, the operator moves the moving detector 6 along the outer wall of the clamp 2. The two sets of detectors 6 slide through the opening of the mounting groove 3, while the sliding shaft 5 slides inside the movable groove 4. The sliding shaft 5 restricts the movement of the detector 6, ensuring that the detector 6 moves along the outer wall of the clamp 2. The two sets of detectors 6 perform non-destructive testing on the pipe. The moving detector 6 facilitates inspection around the pipe, thus solving the problem of the operator needing to rotate the pipe for inspection, greatly saving the operator's physical strength, reducing the workload, and improving the efficiency of pipe inspection, thereby saving inspection time.

[0019] In this embodiment, the movable component includes two sets of movable slots 7 formed on the mounting frame 1. The two sets of movable slots 7 are symmetrically distributed about the central axis of the mounting frame 1. A movable plate 8 is slidably disposed in the movable slot 7. One side of the movable plate 8 is fixedly connected to one end of the connecting plate 9. The component also includes a motor 12 disposed on one side of the mounting frame 1. Screws 11 are rotatably connected in both sets of movable slots 7. One set of screws 11 is fixedly connected to the output end of the motor 12. At the same time, one end of the two sets of screws 11 extends through to one side of the mounting frame 1. A sprocket 13 is fixedly connected to both sets of screws 11. A chain 14 is engaged with the two sets of sprockets 13.

[0020] The motor 12 drives a set of screws 11 to rotate. Under the action of the sprocket 13 and the chain 14, the two sets of screws 11 rotate simultaneously. The two sets of screws 11 drive the moving plate 8 to move in the opening moving groove 7. The moving plate 8 drives the connecting plate 9 to move, thereby driving the two sets of clamps 2 to move, which facilitates the clamping operation of the pipeline and greatly increases the convenience of equipment operation.

[0021] In this embodiment, a protective shell 15 is snapped onto one side of the mounting bracket 1, and the protective shell 15 covers the outside of the sprocket 13 and the chain 14.

[0022] By setting up a protective shell 15 to protect the sprocket 13 and chain 14, the service life of the equipment is increased and the protection of the equipment is improved.

[0023] In this embodiment, both sets of clamps 2 are provided with a plurality of rotating slots 16, which are distributed in an array at equal intervals. A rotating shaft 17 is fixedly connected in the rotating slot 16, a pulley 18 is fixedly connected on the rotating shaft 17, and a baffle 19 is fixedly connected to one end of the rotating shaft 17.

[0024] The rotating groove 16 connects the rotating shaft 17 and the pulley 18 to the mounting frame 1. At the same time, the baffle 19 protects the rotating shaft 17 and the pulley 18. The rotating shaft 17 facilitates the sliding of the pulley 18. After clamping the pipe, the position of the pipe can be finely adjusted by the sliding pulley 18, which increases the convenience and practicality of the equipment.

[0025] It should be noted that this utility model is a non-destructive testing device for pressure pipelines. When the pipeline needs to be clamped, the motor 12 on the mounting frame 1 drives a set of screws 11 to rotate. Under the action of the sprocket 13 and the chain 14, the two sets of screws 11 rotate simultaneously. The two sets of screws 11 drive the moving plate 8 to move within the opening of the moving groove 7, thereby the moving plate 8 drives the connecting plate 9 to move, which in turn drives the two sets of clamps 2 to move. The two sets of clamps 2 clamp the pipeline. After the pipeline is fixed, the operator moves the moving detector 6 along the outer wall of the clamp 2. The two sets of detectors 6 slide through the opening of the mounting groove 3, and at the same time, the sliding shaft 5 slides inside the movable groove 4. The sliding shaft 5 restricts the movement of the detector 6, ensuring that the detector 6 moves along the outer wall of the clamp 2. The two sets of detectors 6 perform non-destructive testing on the pipeline. The moving detector 6 facilitates inspection around the pipeline.
