Abstract
Description
Technical Field
[0001] This utility model is a portable ultrasonic thickness measuring device for pipe inspection, belonging to the technical field of ultrasonic thickness gauges. Background Technology
[0002] Ultrasonic thickness measurement is used to measure the thickness of materials. When the ultrasonic pulse emitted by the probe passes through the object being measured and reaches the material interface, the pulse is reflected back to the probe. The thickness of the material being measured is determined by accurately measuring the time it takes for the ultrasonic wave to travel through the material. This principle can be used to measure any material that allows ultrasonic waves to travel through it at a constant speed.
[0003] When performing ultrasonic thickness measurement on pipes, since pipes are basically cylindrical, conventional thickness gauges are prone to instability, resulting in large errors in the test results. Therefore, to address this issue, a portable ultrasonic thickness measuring device for pipe testing is proposed. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a portable ultrasonic thickness measuring device for pipe inspection, so as to solve the existing problems.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a portable ultrasonic thickness measuring device for pipe inspection, the structure of which includes an ultrasonic thickness gauge and a probe. The probe is connected to the ultrasonic thickness gauge, and a fixing device is connected to the probe. The fixing device consists of an upper fixing block and a lower fixing block. Both the upper fixing block and the lower fixing block are provided with arc-shaped grooves, and the two arc-shaped grooves are combined to form a circular groove. The ultrasonic thickness gauge is a general-purpose device, so it will not be described in detail.
[0006] Furthermore, the probe and the upper fixing block are connected by threads, and the probe extends into the arc-shaped groove of the upper fixing block, with the shape of the probe's detection end matching the curvature of the arc-shaped groove.
[0007] Furthermore, the lower fixing block is provided with a limiting device, and the upper fixing block is provided with a limiting hole that matches the limiting device. The lower fixing block is connected to the upper fixing block through the limiting device.
[0008] Furthermore, a rubber sheet is provided on the arc-shaped groove of the lower fixing block, and the rubber sheet is disposed at the upper and lower ends of the inner wall of the arc-shaped groove of the lower fixing block.
[0009] Furthermore, the limiting device includes a screw, on which a spring is sleeved, and the limiting hole on the upper fixing block is a threaded hole. The threaded hole is a conventional setting and therefore is not shown in the accompanying drawings.
[0010] Furthermore, an upper pressure plate and a lower pressure plate are connected to the screw. The upper pressure plate is fixedly connected to the screw, and the lower pressure plate is fixedly connected to the inner cavity of the lower fixing block. The spring is located between the upper pressure plate and the lower pressure plate. The screw and the lower pressure plate are connected by a thread. When the screw works downward, the upper pressure plate will compress the spring.
[0011] The beneficial effects of this utility model are:
[0012] By using a fixing device to secure the pipe, the test will not be moved, thus ensuring the accuracy of the data.
[0013] Rubber sheets are only installed on the lower fixing block to increase the friction with the pipe and prevent the pipe from moving.
[0014] The limiting device allows the rubber sheet to fit the pipe better, further increasing the friction. Attached Figure Description

[0021] 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.
[0022] Please see Figures 1-4This utility model provides a technical solution for a portable ultrasonic thickness measuring device for pipe inspection: its structure includes an ultrasonic thickness gauge 1 and a probe 2. The probe 2 is connected to the ultrasonic thickness gauge 1. A fixing device 3 is connected to the probe 2. The fixing device 3 consists of an upper fixing block 4 and a lower fixing block 5. Both the upper fixing block 4 and the lower fixing block 5 are provided with arc-shaped grooves 6. The two arc-shaped grooves 6 are combined to form a circular groove.
[0023] The probe 2 and the upper fixing block 4 are threadedly connected by the thread 7. The probe 2 extends into the arc groove 6 of the upper fixing block 4 and the shape of the detection end of the probe 2 matches the curvature of the arc groove 6.
[0024] The lower fixing block 5 is provided with a limiting device 8, and the upper fixing block 4 is provided with a limiting hole that matches the limiting device 8. The lower fixing block 5 is connected to the upper fixing block 4 through the limiting device 8. The lower fixing block 5 has a rubber sheet 9 on its arc groove 6. The rubber sheet 9 is located at the upper and lower ends of the inner wall of the arc groove 6 of the lower fixing block 5. The limiting device 8 includes a screw 801. A spring 802 is sleeved on the screw 801. The limiting hole on the upper fixing block 4 is a threaded hole. An upper pressure plate 803 and a lower pressure plate 804 are also connected to the screw 801. The upper pressure plate 803 is fixedly connected to the screw 801. The lower pressure plate 804 is fixedly connected to the inner cavity of the lower fixing block 5. The spring 802 is located between the upper pressure plate 803 and the lower pressure plate 804. The screw 801 and the lower pressure plate 804 are threadedly connected. When the screw 801 moves downward, the upper pressure plate 803 will compress the spring 802.
[0025] For example, when using it, the pipe to be tested is inserted into the circular ring formed by the two arc grooves 6. Then, by turning the screw 801, the screw 801 will drive the spring 802 to compress downward, thereby making the rubber sheet 9 fit more tightly with the pipe, thus preventing the pipe from moving or slipping. Finally, the thickness is tested by the ultrasonic thickness gauge 1.
[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
