Description

Technical Field

[0001] This utility model relates to the technical field of pipeline weld inspection equipment, and in particular to an ultrasonic device for inspecting pressure pipeline welds. Background Technology

[0002] In modern industrial production, pressure pipelines are widely used in many fields such as petroleum, chemical, and power. The quality of their welds directly affects the safe and stable operation of the entire system. Weld inspection of pressure pipelines is crucial, and ultrasonic testing technology, with its high efficiency, accuracy, and non-destructive characteristics, has become one of the commonly used methods for inspecting pressure pipeline welds.

[0003] Existing ultrasonic equipment for inspecting weld seams in pressure pipelines typically involves manual handheld operation of the ultrasonic testing instrument. Its mechanical structure is relatively simple, relying mainly on the inspector manually moving the ultrasonic probe to fit the weld surface. Utilizing the principle of ultrasonic wave emission and reception, the instrument analyzes the signals reflected back after propagation through the weld material to determine the presence of internal defects.

[0004] Existing ultrasonic equipment for inspecting weld seams in pressure pipelines requires inspectors to hold the ultrasonic testing instrument and keep it stably in contact with the weld seam during long-term inspection operations. This can easily lead to hand fatigue for the workers. Furthermore, when support is needed, insufficient support can cause the device to tilt and fall, damaging the surface. Therefore, an ultrasonic equipment for inspecting weld seams in pressure pipelines is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an ultrasonic device for inspecting weld seams in pressure pipelines. It aims to improve the existing handheld ultrasonic testing instruments, which are prone to causing hand fatigue for operators and, when support is required, are prone to tilting and falling over, damaging the surface of the device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An ultrasonic device for inspecting weld seams in pressure pipelines includes an ultrasonic detector, a cable fixedly connected to the side wall of the ultrasonic detector, an ultrasonic probe at one end of the cable, an adjustment component at the bottom of the ultrasonic detector, and a winding component on the side wall of the ultrasonic detector.

[0008] The adjustment assembly includes a base plate, the side wall of the ultrasonic detector is rotatably connected to the inside of the base plate, a motor is fixedly connected to the side wall of the base plate, a connecting rod is fixedly connected to the output end of the motor, the side wall of the connecting rod is rotatably connected to the inside of the base plate, a worm gear is fixedly connected to the side wall of the connecting rod, a screw is rotatably connected to the inside of the base plate, a worm wheel is fixedly connected to the side wall of the screw, the connecting rod meshes with the worm wheel, a slider is threadedly connected to the side wall of the screw, a rotating bar is rotatably connected inside the slider, and one end of the rotating bar is rotatably connected to the lower surface of the ultrasonic detector.

[0009] As a further description of the above technical solution:

[0010] The winding assembly includes a fixed plate and a partition plate. The side wall of the fixed plate is fixedly connected to the side wall of the ultrasonic detector, and the side wall of the partition plate is fixedly connected inside the fixed plate. The side wall of the cable is attached to the side wall of the partition plate.

[0011] As a further description of the above technical solution:

[0012] The base plate is provided with a mounting shell inside, and an electromagnet is provided inside the mounting shell;

[0013] As a further description of the above technical solution:

[0014] A clamping plate is rotatably connected to the upper surface of the fixed plate, and a clamping rod is fixedly connected to the side wall of the clamping plate;

[0015] As a further description of the above technical solution:

[0016] A mounting plate is fixedly connected to the upper surface of the fixed plate, and a clamping block is rotatably connected inside the mounting plate;

[0017] As a further description of the above technical solution:

[0018] The side wall of the clamping rod is slidably connected to the side wall of the clamping block to prevent the cable from falling off;

[0019] As a further description of the above technical solution:

[0020] A fixing block is fixedly connected to the side wall of the clamping block, and a spring is provided on the lower surface of the fixing block;

[0021] As a further description of the above technical solution:

[0022] One end of the spring is fixedly connected to the upper surface of the mounting plate, and the other end of the spring is fixedly connected to the fixing block.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by activating the electromagnet, the energized electromagnet can attract the base plate onto the pipeline. Then, the motor is started to drive the connecting rod to rotate, causing the worm gear to drive the worm wheel to rotate, which in turn causes the screw to rotate. Through the threaded connection, the slider slides, which in turn pushes the rotating bar to rotate, thereby making the ultrasonic detector rotate and achieving the effect of making the ultrasonic detector stand upright. This solves the problem that some ultrasonic equipment used for inspecting weld seams of pressure pipelines requires the inspector to hold the ultrasonic detector at all times, which easily leads to hand fatigue of the operator. Furthermore, when support is needed, insufficient support capacity can easily cause the device to tilt and fall, damaging its appearance. The above structure alleviates the hand fatigue of the inspector and improves the support effect of the equipment.

[0025] 2. In this utility model, the cable is wound around the fixing plate and blocked by the partition to prevent the cable from getting tangled together. Then, the clamping rod and the clamping block are pressed together to compress the spring and make the clamping block lock the clamping rod to achieve a fixing effect. This allows the cable to remain stable in the winding state and avoids damage or inconvenience caused by loosening or displacement. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 An embodiment of this utility model provides an ultrasonic device for inspecting weld seams in pressure pipelines, comprising an ultrasonic detector 1, a cable 2 fixedly connected to the side wall of the ultrasonic detector 1, an ultrasonic probe 3 provided at one end of the cable 2, an adjustment assembly provided at the bottom of the ultrasonic detector 1, and a winding assembly provided on the side wall of the ultrasonic detector 1; the adjustment assembly includes a base plate 4, the side wall of the ultrasonic detector 1 is rotatably connected to the inside of the base plate 4, a motor 5 fixedly connected to the side wall of the base plate 4, a connecting rod 6 fixedly connected to the output end of the motor 5, the side wall of the connecting rod 6 is rotatably connected to the inside of the base plate 4, a worm gear 7 fixedly connected to the side wall of the connecting rod 6, a screw 8 rotatably connected to the inside of the base plate 4, a worm wheel 9 fixedly connected to the side wall of the screw 8, the connecting rod 6 meshing with the worm wheel 9, a slider 10 threadedly connected to the side wall of the screw 8, a rotating bar 11 rotatably connected inside the slider 10, one end of the rotating bar 11 rotatably connected to the lower surface of the ultrasonic detector 1, a mounting shell 12 provided inside the base plate 4, and an electromagnet 13 provided inside the mounting shell 12;

[0035] When inspecting pressure pipelines, the electromagnet 13 inside the mounting shell 12 of the base plate 4 plays its role. After the electromagnet 13 is activated, the magnetic force generated by the energized electromagnet attracts the base plate 4 to the surface of the pressure pipeline. This attraction ensures the stability of the entire equipment during inspection. After the equipment is stable, the motor 5 is started. The motor 5 drives the connecting rod 6 to rotate, causing the worm 7 fixed to its side wall to rotate accordingly. The worm 7 meshes with the worm wheel 9, converting the rotation of the worm 7 into the rotational motion of the worm wheel 9. Since the worm wheel 9 is fixed on the screw 8, the rotation of the worm wheel 9 drives the screw 8 to rotate synchronously. When the screw 8 rotates, the slider 10 slides along the axial direction of the screw 8. During the sliding process, the slider 10 pushes the rotating bar 11 to rotate. The rotation of the rotating bar 11 drives the ultrasonic detector 1 to rotate around the rotation connection point with the base plate 4, realizing the adjustment of the angle of the ultrasonic detector 1. This facilitates the inspection personnel to observe and inspect the pipeline weld at different positions and angles, adapting to various complex inspection conditions. After the equipment angle adjustment is completed, The ultrasonic probe 3 is attached to the pipe. The ultrasonic detector 1 generates an electrical signal, which is transmitted to the ultrasonic probe 3 via cable 2. Cable 2 acts as a bridge for signal transmission, ensuring stable transmission of the electrical signal from the ultrasonic detector 1 to the ultrasonic probe 3. The ultrasonic probe 3 converts the received electrical signal into ultrasonic waves and emits them into the weld material of the pressure pipe. When the ultrasonic waves propagate in the weld material, they encounter different medium interfaces, such as the interface between defects and normal materials, resulting in reflection, refraction, and scattering. These reflected ultrasonic waves are received by the ultrasonic probe 3, which converts them back into electrical signals and transmits them back to the ultrasonic detector 1 via cable 2. The ultrasonic detector 1 amplifies, processes, and analyzes the received electrical signals. By deeply analyzing the signal characteristics, such as the signal amplitude and propagation time, the inspectors can accurately determine whether there are defects inside the weld, as well as key information such as the location, size, and nature of the defects, thus successfully completing the comprehensive inspection of the pressure pipe weld.

[0036] Reference Figure 1 and Figure 4 The winding assembly includes a fixed plate 14 and a partition plate 15. The side wall of the fixed plate 14 is fixedly connected to the side wall of the ultrasonic detector 1, and the side wall of the partition plate 15 is fixedly connected to the inside of the fixed plate 14. The side wall of the cable 2 is attached to the side wall of the partition plate 15. A clamping plate 16 is rotatably connected to the upper surface of the fixed plate 14. A clamping rod 17 is fixedly connected to the side wall of the clamping plate 16. An installation plate 18 is fixedly connected to the upper surface of the fixed plate 14. A clamping block 19 is rotatably connected inside the installation plate 18. The side wall of the clamping rod 17 is slidably connected to the side wall of the clamping block 19 to prevent the cable 2 from falling off. A fixing block 20 is fixedly connected to the side wall of the clamping block 19. A spring 21 is provided on the lower surface of the fixing block 20. One end of the spring 21 is fixedly connected to the upper surface of the installation plate 18, and the other end of the spring 21 is fixedly connected to the fixing block 20.

[0037] When cable 2 is being wound up, cable 2 is attached to the side wall of partition 15. When the equipment is moving or during routine winding operations, cable 2 is prone to becoming tangled due to various external forces. Partition 15 provides an orderly storage path for cable 2, allowing cable 2 to be arranged along a specific direction, thus initially organizing cable 2 and greatly reducing the probability of cable 2 becoming tangled during equipment movement. When cable 2 needs to be fixed, the clamping plate 16 is rotated, causing the clamping rod 17 to insert into the side wall of the clamping block 19. During this process, the spring 21 is compressed and contracted, and its elastic force causes the clamping block 19 to generate a continuous and stable clamping force on the clamping rod 17. In this way, the clamping plate 16 is firmly fixed, thereby fixing cable 2. When cable 2 is in the winding state, this fixing structure can effectively prevent cable 2 from being pulled arbitrarily due to slight external shaking, accidental contact, etc., ensuring the stability of cable 2 after winding and avoiding equipment failure or signal transmission problems that may be caused by loose cable 2.

[0038] Working Principle: When pressure pipelines need to be inspected, the electromagnet 13 in the mounting shell 12 inside the base plate 4 is activated. The energized electromagnet 13 generates magnetic force, firmly attaching the base plate 4 to the surface of the pressure pipeline, ensuring the stability of the entire device during the inspection process and preventing movement. Then, the motor 5 is activated, driving the connecting rod 6 to rotate, causing the worm gear 7 to rotate accordingly. The worm gear 7 meshes with the worm wheel 9, and the rotation of the worm gear 7 drives the worm wheel 9 to rotate. Since the worm wheel 9 is fixed to the screw 8, the screw 8 also rotates. The rotation of the screw 8 causes the slider 10 to slide along the axial direction of the screw 8. When the slider 10 slides, it pushes the rotating bar 11 to rotate, thereby causing the ultrasonic detector 1 to rotate around the rotation connection point with the base plate 4, allowing for angle adjustment of the ultrasonic detector 1, facilitating viewing from different angles by the inspector. Then, the ultrasonic probe 3 is attached to the pipeline. The ultrasonic detector 1 generates an electrical signal, which is transmitted to the ultrasonic probe 3 via the cable 2. The ultrasonic probe 3 converts the electrical signal into ultrasonic waves and emits them into the pressure pipeline. In pipeline weld materials, when ultrasonic waves propagate through the weld material and encounter different media interfaces, such as the interface between defects and normal materials, reflection, refraction, and scattering occur. The reflected ultrasonic waves are received by the ultrasonic probe 3, converted back into electrical signals, and transmitted back to the ultrasonic detector 1 via the cable 2. The ultrasonic detector 1 amplifies, processes, and analyzes these electrical signals, and determines whether there are defects inside the weld, as well as the location, size, and nature of the defects, based on the characteristics of the signals, thereby completing the inspection of the pressure pipeline weld. When the cable 2 is wound up, the cable 2 is attached to the side wall of the partition 15. The partition 15 plays a role in guiding and initially organizing the cable 2, preventing the cable 2 from becoming tangled and messy during equipment movement. When it is necessary to fix the cable 2, the clamping plate 16 is rotated, causing the clamping rod 17 to insert into the side wall of the clamping block 19. The elastic force of the spring 21 causes the clamping block 19 to generate a certain clamping force on the clamping rod 17, thereby fixing the clamping plate 16 and thus fixing the cable 2, preventing the cable 2 from being pulled arbitrarily during the winding state.
