Description

Technical Field

[0002] In the industrial field, pipelines, as key carriers of material transportation and energy conduction, are widely used in many industries such as petrochemicals, electric power, metallurgy, and urban water and gas supply. Their operational safety and stability are directly related to the normal operation of the entire production system and the stability of people's lives. Pipelines serve in complex working conditions for a long time, and are affected by multiple factors such as internal medium pressure, external environmental erosion, and thermal stress caused by temperature changes. The pipe wall is prone to corrosion, wear, deformation and thinning, and a thickness gauge is needed to measure the thickness of the pipeline.

[0003] Chinese utility model patent publication number: CN 222069614 U, discloses: a pressure pipe wall thickness measuring device, which wirelessly controls the rotation of the motor, which drives the driving wheel to roll on the pipe wall surface; and is equipped with multiple electromagnetic ultrasonic thickness gauges, eliminating the need to apply coupling agent to the outer wall of the pipe. The thickness measuring probes and the pipe perform non-contact measurement, facilitating automatic measurement of the pipe wall thickness. The device can achieve simultaneous automatic measurement of multi-point wall thickness, improving the efficiency of pipe wall thickness measurement and enhancing the efficiency of detection data collation and analysis. However, the drive module of the pressure pipe wall thickness measuring device can only drive the thickness measuring device to move radially along the pipe and cannot rotate around the center of the pipe.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1: Figure 1-6As shown, the utility model provides an ultrasonic measuring device for pipe wall thickness, including a clamping base body 1, an inner wall of the clamping base body 1 is fixedly connected to a rubber pad 2, an outer wall of the clamping base body 1 is provided with a groove 3, the upper and lower ends of the outer wall of the clamping base body 1 are fixedly connected to a track 4, a side of the track 4 away from the groove 3 is provided with a slide groove 5, a side of the track 4 close to the groove 3 is fixedly connected to a rack 6, two identical tracks 4 are symmetrically arranged, a moving component 7 is arranged at the center of the two tracks 4, the clamping base body 1, the rubber pad 2, the groove 3, the track 4, the slide groove 5, the rack 6 and the moving component 7 together constitute a clamping base component 1 8, a clamping base component 2 9 is provided on the side of the clamping base component 1 8 close to the rubber pad 2, and a locking bolt 10 is provided between the clamping base component 1 8 and the clamping base component 2 9;

[0033] Specifically, the rubber pad 2 is made of silicone rubber, and the slide groove 5 is slidably connected to the rotating rod 703 and the screw 705. Advantageously, the rubber pad 2 is made of silicone rubber. During use, the probe of the ultrasonic thickness gauge 707 contacts the rubber pad 2, which can not only tightly adhere to the outer wall of the pipe, ensuring effective ultrasonic transmission and avoiding signal attenuation during testing, but also prevent the clamp body 1 from scratching the pipe surface.

[0034] Specifically, the clamp body 1 has an arc-shaped structure and adapts to the outer wall of the pipe, and the track 4 adapts to the clamp body 1. Advantageously, the clamp body 1 is designed in an arc shape that fits the outer wall of the pipe, fully enveloping the pipe, increasing the contact area and allowing the ultrasonic detection signal to evenly cover the pipe surface, improving detection accuracy. The track 4 adapts to the clamp body 1, ensuring that the mobile assembly 7 is securely installed without shaking or offsetting, thereby ensuring the reliability of subsequent position adjustment of the ultrasonic thickness gauge 707.

Advantageously, the movable assembly 7 can drive the ultrasonic thickness gauge 707 to move horizontally and vertically along the clamp body 1, thereby improving the measurement performance of the ultrasonic thickness gauge 707.

[0038] Specifically, worm 709 and worm gear 710 are meshed, and mounting bracket 711 is compatible with the probe of ultrasonic thickness gauge 707. Advantages include smooth transmission and high precision, as well as a self-locking function that allows the probe to be stably locked after adjusting the probe angle, ensuring that the probe is perpendicular to the pipe wall and preventing it from swinging due to external forces. Mounting bracket 711 is compatible with the probe of ultrasonic thickness gauge 707, ensuring secure probe installation and stable signal transmission, reducing the risk of measurement data deviation due to probe loosening.

[0039] Specifically, the first clamp assembly 8 and the second clamp assembly 9 are locked and fixed by a locking bolt 10. The advantage is that the first clamp assembly 8 and the second clamp assembly 9 are locked by the locking bolt 10, the installation and removal process is simple and quick, and the distance between the clamps can be flexibly adjusted according to different pipe diameters. The applicability is strong. After locking, the two clamps form a stable encircling structure, firmly fitting the pipe, ensuring the overall stability of the device during the inspection process.

[0040] Working principle: in use, the clamp seat assembly one 8 and the clamp seat assembly two 9 are locked on the outer wall of the pipeline by the locking bolt 10, and the rubber pad 2 is tightly attached to the outer wall of the pipeline, if the horizontal position of the ultrasonic thickness gauge 707 needs to be adjusted, one hand holds the rotating rod 703 and slowly rotates, at this time the gear 704 rotates with the rotating rod, and the moving assembly 7 is driven to move along the track 4 stably and linearly by the meshing transmission of the rack 6, until the ultrasonic thickness gauge 707 is accurately aligned with the predetermined measurement starting point, the screw rod 705 is rotated, and the lifting seat 706 moves up and down along the slide rod 702 according to the screw transmission principle, the ultrasonic thickness gauge 707 is adjusted to the appropriate height to meet the detection process requirements, if the outer wall of the pipeline is not flat enough, the probe angle needs to be adjusted, the worm 709 is rotated, the worm and the worm gear 710 are meshed and transmitted, the fixed seat 711 and the probe are slowly rotated, so that the probe of the ultrasonic thickness gauge 707 is perpendicular to the pipe wall, the probe of the ultrasonic thickness gauge 707 is in contact with the rubber pad 2, the rubber pad 2 can tightly attach to the outer wall of the pipeline to ensure the effective transmission of ultrasonic waves and avoid signal attenuation during detection, the probe of the ultrasonic thickness gauge 707 emits ultrasonic pulses, which penetrate the rubber pad 2 into the pipeline, receives the reflected echo signal and analyzes and processes it, the position of the adjustable moving assembly 7 can be adjusted, so that the wall thickness of multiple positions on the surface of the pipeline can be measured, after the measurement is completed, the measuring device is pulled along the pipeline to measure the wall thickness of multiple positions.
