Description

Technical Field

[0001] The utility model relates to the technical field of wall thickness measurement, in particular to a wall thickness measuring device. Background Art

[0002] Wall thickness measurement is an important construction measurement task, which involves the precise determination of the actual thickness of the building wall. This measurement is of great significance for ensuring the accuracy of building design, controlling construction quality, and evaluating the safety of the building in the later stage. Wall thickness is usually measured by direct and indirect methods. The direct measurement method is to measure the thickness of the wall directly by physical means, which can be done by a tape measure, thickness gauge or other precise measuring tools. This method is simple and direct, and the measurement results are accurate, but in some cases, such as when the wall surface is uneven or it is difficult to directly contact both sides of the wall, direct measurement may be limited. Indirect measurement methods use various non-contact technologies to estimate wall thickness, such as ultrasonic ranging, laser scanning and other advanced technologies. These technologies can infer the thickness of the wall by measuring the propagation time or reflection characteristics of the wave without directly touching the wall. Indirect measurement methods are particularly useful for high walls or walls that are difficult to access, but their accuracy and reliability are usually affected by the measurement environment and equipment performance.

[0003] Among them, the most widely used technology is to use ultrasonic thickness gauge to detect the thickness of the wall. The probe of the ultrasonic thickness gauge is attached to the surface of the wall, and the ultrasonic thickness gauge is used to control it. The probe emits ultrasonic waves that receive feedback. The ultrasonic thickness gauge reads and calculates the data to get the thickness of the wall. During long-term use, the contact surface of the thickness probe will experience a certain degree of wear. These probes usually use acrylic resin as the surface material. Over time, its surface may become rougher. The increase in roughness may reduce the sensitivity of the probe, thereby affecting its measurement accuracy and causing deviations in the displayed results.

[0004] Therefore, a wall thickness measuring device is proposed to solve or alleviate the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] A wall thickness measuring device, such as Figure 1 As shown, it includes an ultrasonic thickness gauge 1, a wire 2 coupled thereto, and a probe 3 coupled to the wire 2. The end of the probe 3 away from the wire 2 is fixedly connected to a contact portion 4 made of acrylic resin, and the contact portion 4 is in a truncated cone shape. The outer side of the probe 3 is movably connected to a grinding component that can rub the end surface of the contact portion 4.

[0021] like Figure 2 and 3 As shown, the grinding assembly includes a sliding ring 6, two hinged rods 1 8 and a hinged rod 2 9 rotatably connected to the outer ring of the sliding ring 6, a top plate 10 and a top plate 2 11, and a 500-mesh sandpaper 12 that can contact the end surface of the contact portion 4, and the cross-sections of the top plate 10 and the top plate 2 11 are both semicircular, and the radii of the top plate 10 and the top plate 2 11 are both larger than the maximum radius of the contact portion 4, the top plate 10 is fixedly connected to the same end of the two hinged rods 1 8, the top plate 2 11 is fixedly connected to the same end of the two hinged rods 2 9, and the sandpaper 12 is fixedly connected to the side of the top plate 10 and the top plate 2 11 facing the contact portion 4, the outer ring of the sliding ring 6 is provided with two parallel parallel surfaces, the hinged rod 1 8 and the hinged rod 2 9 are rotatably connected to the parallel surfaces through a rotating pin 7, the outer ring of the probe 3 is provided with an annular groove 5, the groove width of the annular groove 5 is smaller than the width of the sliding ring 6, and the sliding ring 6 is sleeved in the annular groove 5.

[0022] When the utility model measures the thickness of a wall, the operator only needs to rotate the hinged rod 1 8 and the hinged rod 2 9 so that the top plate 10 and the top plate 2 11 no longer cover the end surface of the contact portion 4, and then make the contact portion 4 on the probe 3 contact the surface of the wall, and then control it through the ultrasonic thickness gauge 1, use the wire 2 to transmit the probe 3, and the probe 3 will emit an ultrasonic wave, which will be transmitted to the wall through the contact portion 4, and the ultrasonic wave will be fed back to the probe 3 through the wall, and then fed back to the ultrasonic thickness gauge 1 again through the wire 2, so as to complete the measurement of the wall thickness. After long-term use, if the end surface of the contact portion 4 is severely worn, the operator only needs to rotate the hinged rod 1 8 and the hinged rod 2 9 so that the top plate 10 and the top plate 2 11 are closed again. At this time, the top plate 10 and the top plate 2 11 will block the end face of the contact part 4, and then the top plate 10 and the top plate 2 11 will be pressed down, and the two will transmit the force to the rotating pin 7 through the hinge rod 1 8 and the hinge rod 2 9. The rotating pin 7 makes the sliding ring 6 displace in the annular groove 5 along the length direction of the contact part 4 until the sandpaper 12 on the top plate 10 and the top plate 2 11 can contact the end face of the contact part 4, and even the sliding ring 6 can be rotated in the circumferential direction of the annular groove 5, so that the sandpaper 12 rubs the end face of the contact part 4 back and forth, thereby completing the grinding of the end face of the contact part 4, and then the wall thickness measurement can be performed again. In this way, the probe 3 can maintain a longer service life without affecting the sensitivity of the probe 3 and the accuracy of the data.
