Description

Technical Field

[0001] This utility model belongs to the field of steel pipe inspection technology, and in particular relates to a pipe dent detection device. Background Technology

[0002] Handheld ultrasonic thickness gauges are used to contact and measure pipe wall thickness. By observing changes in wall thickness, it can identify thinning caused by pits or corrosion. The instrument is easy to operate and suitable for testing small pipes or localized areas. It can also be used to detect internal depressions in pipes.

[0003] Because the probe of a handheld ultrasonic thickness gauge needs to be held continuously to inspect along the steel pipe, the arm is stretched out for a long time and kept moving in a straight line, which can easily cause arm soreness, making the operation of a conventional handheld ultrasonic thickness gauge quite troublesome.

[0004] Therefore, we propose a pipe dent detection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the cumbersome operation of conventional handheld ultrasonic thickness gauges, and to propose a device for detecting pipe dents.

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

[0007] A pipe dent detection device includes an ultrasonic thickness gauge probe. A vehicle body is movably fitted around the lower part of the ultrasonic thickness gauge probe. Rollers are rotatably mounted on the side of the vehicle body. Magnetic rings are fixedly fitted around the outside of the rollers. A leather sleeve covers the outside of the rollers and the magnetic rings. A spring is fixedly mounted around the outside of the ultrasonic thickness gauge probe, and the lower end of the spring is fixedly connected to the vehicle body. The vehicle body is placed on the target steel pipe, and the magnetic rings magnetically attract the probe. The spring force acts on the ultrasonic thickness gauge probe, pulling it downwards along the outside of the target steel pipe to detect dents, thus reducing operational difficulty.

[0008] Preferably, the vehicle body includes a base, a fixed shaft is fixedly connected to the side of the base, a guide ring is fixedly connected inside the base, the guide ring has an arc that matches the spring sheet, and the ultrasonic thickness gauge probe is slidably inserted into the guide ring.

[0009] Preferably, the roller includes a wheel body, and a first retaining ring is fixedly connected to the outside of the wheel body, with the magnet ring fixedly mounted on the wheel body. The wheel body serves to block the magnet ring from misalignment.

[0010] Preferably, the spring includes a spring body, one end of which is fixedly connected to a connecting piece, the lower end of which is fixedly connected to a base, and the spring body is fixedly mounted on the upper part of the ultrasonic thickness gauge probe. The spring body provides a downward elastic force to the ultrasonic thickness gauge probe, facilitating its retention on the target steel plate.

[0011] Preferably, the spring sheet further includes a reinforcing ring, which is fixedly connected to the upper part of the ultrasonic thickness gauge probe. The reinforcing ring increases the fixation range between the spring sheet and the ultrasonic thickness gauge probe.

[0012] Preferably, the sheath includes a sleeve body, and a second retaining ring is fixedly connected inside the sleeve body. The sleeve body and the second retaining ring are an integral structure. The sleeve body is fitted over the magnet ring and the first retaining ring, and the second retaining ring is positioned against the outer wall of the first retaining ring. By using the second retaining ring to block the roller and the magnet ring, the sheath increases the friction between the device and the target steel pipe.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Place the vehicle body on the target steel pipe, use the magnetic ring to magnetically attract it to the steel pipe, and use the elastic force of the spring to act on the ultrasonic thickness gauge probe. The ultrasonic thickness gauge probe acts downward on the steel pipe, pulling the ultrasonic thickness gauge probe to detect the steel pipe along the outside of the target steel pipe, reducing the difficulty of operation.

[0015] 2. Use the second retaining ring to block outside the roller and magnet ring, and use the leather sleeve to increase the friction between the device and the target steel pipe. Attached Figure Description

The lower end of the connecting piece 42 is fixedly connected to the base 21. The spring body 41 is fixedly installed on the upper part of the ultrasonic thickness gauge probe 1.

The elastic force of the spring piece 4 acts on the ultrasonic thickness gauge probe 1, and the ultrasonic thickness gauge probe 1 acts downward on the steel pipe, pulling the ultrasonic thickness gauge probe 1, so that the ultrasonic thickness gauge probe 1 detects the steel pipe along the outside of the target steel pipe.
