Description

Technical Field

[0001] The utility model relates to the technical field of pipeline measurement, in particular to an ultrasonic thickness gauge used for pipeline detection. Background Art

[0002] The ultrasonic thickness gauge measures thickness based on the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the material interface, the pulse is reflected back to the probe and the thickness of the material to be measured is determined by accurately measuring the time it takes for the ultrasonic wave to propagate in the material. This principle can be used to measure various materials that allow ultrasonic waves to propagate at a constant speed inside them.

[0003] The existing ultrasonic thickness gauge detects the thickness of the pipeline by inserting the connector into the connection of the instrument, then holding the instrument and placing the ultrasonic generator against the surface of the pipeline, and then emitting ultrasonic waves. However, shaking may occur during the detection. During the shaking process, the connector may fall off from the connection of the instrument, which will affect the operation of the detection operation. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 3 , the utility model provides an embodiment: an ultrasonic thickness gauge for pipeline detection, comprising a detection rod 1, the outer wall of the detection rod 1 is fixedly connected to a thickness gauge body 2, one end of the detection rod 1 is fixedly connected to a first threaded rod 3, the outer wall of the first threaded rod 3 is fixedly connected to a sliding rod 4, the outer wall of the sliding rod 4 is fixedly connected to a baffle 5, the outer wall of the first threaded rod 3 is threadedly connected to a movable ring 6, the outer wall of the first threaded rod 3 is slidably connected to a slip ring 7, the outer wall of the slip ring 7 is fixedly connected to a connecting seat 8, the inner part of the connecting seat 8 is rotatably connected to a connecting plate 9, the outer wall of the connecting plate 9 is rotatably connected to a push plate 10, the inner part of the push plate 10 is rotatably connected to a rotating wheel 11, the outer wall of the rotating wheel 11 is fixedly connected to a clamping plate 12, and the outer wall of the thickness gauge body 2 is provided with a mounting assembly;

[0023] Specifically, when the position of the thickness gauge body 2 needs to be fixed, the movable ring 6 is rotated to slide on the outer wall of the first threaded rod 3, which makes the movable ring 6 slide on the first threaded rod 3. At the same time, as the movable ring 6 slides, the slip ring 7 will also slide on the outer wall of the first threaded rod 3, which can drive the connecting plate 9 to rotate inside the connecting seat 8 and push the push plate 10 to expand outward, which makes the push plate 10 move along the thickness gauge body 2, thereby ensuring the accuracy of the measurement. At the same time, the push plate 10 and the clamping plate 12 are connected by the rotating wheel 11. As the push plate 10 is pushed, the clamping plate 12 will be gradually pushed toward the inner wall of the pipe until it is completely close to it, which ensures that the position of the thickness gauge in the pipe is stable and accurate without moving or shaking, thereby improving the reliability and accuracy of the measurement, minimizing the influence of external factors on the measurement results, and ensuring that the thickness gauge can work stably and provide accurate measurement data.

[0024] Reference Figure 1-Figure 3The mounting assembly includes a fixing sleeve 13, the outer wall of which is fixedly connected to the outer wall of the thickness gauge body 2; a collecting cylinder 14 is fixedly connected inside the fixing sleeve 13, and a collecting roller 15 is rotatably connected inside the collecting cylinder 14; a connecting wire 16 is sleeved on the outer wall of the collecting roller 15, and one end of the connecting wire 16 is fixedly connected to the inside of the thickness gauge body 2; a straight rod 17 is rotatably connected inside the collecting roller 15, and the outer wall of the straight rod 17 penetrates into the inside of the collecting cylinder 14; a second threaded rod 22 is fixedly connected to the outer wall of the straight rod 17, and a threaded cylinder 18 is threadedly connected to the outer wall of the second threaded rod 22; a knob 19 is fixedly connected to the outer wall of the threaded cylinder 18, and the outer wall of the threaded cylinder 18 is fixedly connected to the inside of the collecting roller 15; a spring 21 is arranged inside the collecting cylinder 14, one end of the spring 21 is fixedly connected to the inside of the collecting cylinder 14, and the other end of the spring 21 is fixedly connected to the top plate 20;

[0025] Specifically, when the connecting wire 16 needs to be stored, by turning the knob 19, the threaded barrel 18 and the collecting roller 15 are driven to rotate at the same time, which enables the collecting roller 15 to effectively wind up the connecting wire 16 and collect it neatly, avoiding the situation where the cables are tangled in a messy way. At the same time, rotating the straight rod 17 can drive the second threaded rod 22 to continuously screw into the interior of the threaded barrel 18 until it is tightly attached to the surface of the collecting barrel 14, which can fix the collecting roller 15 to ensure that its position is stable and will not move or loosen during the storage process. In addition, the spring 21 pushes the top plate 20 to limit the connecting wire 16, so that the connecting wire 16 can be firmly maintained in the appropriate position, avoiding excessive tension or relaxation, thereby improving the reliability and practicality of the thickness gauge, thereby avoiding the confusion and entanglement of the cables, ensuring that the circuit of the thickness gauge is neat and orderly, and improving its practicality and long-term stability.

[0026] Working principle: When the position of the thickness gauge body 2 needs to be fixed, the movable ring 6 is rotated to slide on the outer wall of the first threaded rod 3, so that the movable ring 6 can continuously push the sliding ring 7 to slide on the outer wall of the first threaded rod 3, thereby rotating the connecting plate 9 inside the connecting seat 8 to push and open the push plate 10, and then the push plate 10 and the clamping plate 12 are connected by the rotating wheel 11, so that the push plate 10 can push the clamping plate 12 until the clamping plate 12 is completely close to the inner wall of the pipe, thereby achieving the effect of firmly fixing the position of the thickness gauge and improving the stability of the thickness gauge. When the connecting wire 16 needs to be stored, the threaded barrel 18 and the collecting roller 15 are driven to rotate by turning the knob 19, so that the collecting roller 15 can wind and collect the connecting wire 16, and at the same time, the straight rod 17 can drive the second threaded rod 22 to continuously screw into the threaded barrel 18 until it is tightly attached to the surface of the collecting barrel 14 to fix the collecting roller 15, wherein the spring 21 can push the top plate 20 to limit the connecting wire 16, thereby achieving the effect of storing the thickness gauge line, avoiding the entanglement of the connecting wire 16, and improving the practicality of the thickness gauge.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
