Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline flaw detection, and particularly relates to a support frame for a pipeline electromagnetic ultrasonic flaw detection device. Background Art

[0002] There are five main methods for pipeline flaw detection: ultrasonic testing, radiographic testing, magnetic particle testing, penetrant testing, and eddy current testing. With the integration of electromagnetic and ultrasonic circuits, portable flaw detectors are becoming increasingly popular. Users simply hold a tablet-sized flaw detector, pair it with a probe, and, supported by a bracket, place it against the pipeline for flaw detection.

[0003] In pipeline inspection in industries such as petroleum, natural gas, chemical, and electric power, for taller or thicker pipelines, the probe of the portable flaw detector needs to be clamped on the outside of the pipeline using an arc-shaped support frame, freeing the user's hands.

[0004] When the probe is attached to the pipeline, two arc-shaped support frames are generally used to clamp the pipeline from both sides to support the probe. However, the outer wall of the pipeline is laid with cables for each electric valve, so that the cable pipeline blocks the arc-shaped support frame. The arc-shaped support frame causes the probe to tilt near the cable pipeline on the outer wall of the pipeline, creating a blind spot for flaw detection. For this reason, we propose a support frame for pipeline electromagnetic ultrasonic flaw detection equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a support frame for a pipeline electromagnetic ultrasonic flaw detection device, which can relatively flexibly cover the cable pipeline, reduce the degree of warping of the support frame outside the pipeline, facilitate the probe to adhere to the outer wall of the pipeline, and reduce blind spots in flaw detection.

[0006] The technical solutions adopted in this application are as follows:

[0007] A support frame for a pipeline electromagnetic ultrasonic flaw detection device comprises a mounting frame in an annular structure, a first cloth belt and a second cloth belt are fixed to two sides of the mounting frame respectively, a steel ring is fixed to the end of the first cloth belt away from the mounting frame, the interior of the steel ring is passed through by the end of the second cloth belt away from the mounting frame, a threaded pipe is installed through the side of the steel ring away from the first cloth belt, the central axis of the threaded pipe coincides with the central axis of the steel ring, a locking bolt is installed axially in the threaded pipe, one end of the locking bolt extends into the interior of the steel ring, when inspecting the pipeline, a probe is placed against the position to be inspected on the pipeline, and then the first cloth belt and the second cloth belt are clamped around the pipeline from both sides respectively, and the second cloth belt is tightened. One end of the belt passes through the steel ring until it is tightened, and then the locking bolt is turned forward to extend along the threaded tube into the interior of the steel ring, so that one end of the locking bolt cooperates with the steel ring to clamp the second cloth belt, and the first cloth belt and the second cloth belt are locked under the action of friction, thereby restraining the probe to the outside of the pipeline. Even if there is a cable pipeline at this position, the first cloth belt and the second cloth belt can wrap the cable pipeline more softly, reducing the degree of warping of the support frame outside the pipeline, making it convenient for the probe to stick to the outer wall of the pipeline. After the flaw detection is completed, the locking bolt can be reversed to loosen the second cloth belt, so as to pull the first cloth belt and the second cloth belt to rotate the probe and freely adjust the flaw detection angle and position. In this way, areas outside the pipeline and cable pipeline should be inspected as much as possible to reduce blind spots in flaw detection.

[0008] A leather strip is axially sewn on the outside of the second cloth tape, and the width of the leather strip is greater than the outer diameter of the locking bolt. When the locking bolt rotates forward, the leather strip is squeezed and then pressed against the second cloth tape. The leather strip is used to protect the second cloth tape and prevent the locking bolt from directly wearing the second cloth tape.

[0009] An outer sheath is fixed to one end of the second cloth belt passing through the steel ring. The outer sheath supports and keeps one end of the second cloth belt flat. One end of the second cloth belt can pass straight through the steel ring to prevent the end of the second cloth belt from tilting up and blocking the steel ring, and can drive one end of the second cloth belt to fall naturally and tighten quickly.

[0010] A handle is fixed to the end of the locking bolt away from the steel ring. The handle is held by hand to facilitate the rotation of the locking bolt, while maintaining a safe distance from the steel ring to prevent the locking bolt from being completely immersed in the steel ring.

[0011] A steel plate is integrally installed on the inner side of the steel ring opposite to the locking bolt. The diameter of the steel plate is larger than the outer diameter of the locking bolt. After the locking bolt rotates forward, the leather strip is squeezed and then pressed against the second cloth belt. The leather strip is used to protect the second cloth belt to prevent the locking bolt from directly wearing the second cloth belt.

[0012] A circular groove is provided in the middle of the steel disc near the threaded tube, and the diameter of the circular groove is larger than the outer diameter of the locking bolt. After the locking bolt squeezes the second cloth belt, the second cloth belt partially extends into the circular groove, which can increase the supporting area of the second cloth belt and the steel disc in the axial direction of the second cloth belt, thereby improving the firmness of the clamping of the second cloth belt.

[0013] The technical effects achieved by this utility model are:

[0014] The present invention relates to a support frame for an electromagnetic ultrasonic flaw detection device for pipelines. When flaw detection is completed, the probe is placed on the pipeline at the position to be detected, and then the first cloth belt and the second cloth belt are clamped on the pipeline from both sides, one end of the second cloth belt is passed through the steel ring until it is tightened, and then the locking bolt is turned forward to extend along the threaded pipe into the interior of the steel ring, so that one end of the locking bolt cooperates with the steel ring to clamp the second cloth belt, and the first cloth belt and the second cloth belt are locked under the action of friction, thereby restraining the probe to the outside of the pipeline. Even if there is a cable pipeline at this position, the first cloth belt and the second cloth belt can relatively softly cover the cable pipeline, reduce the degree of warping of the support frame on the outside of the pipeline, and facilitate the probe to be close to the outer wall of the pipeline. After the flaw detection is completed, the locking bolt can be reversed to loosen the second cloth belt, so as to pull the first cloth belt and the second cloth belt to rotate the probe, and freely adjust the flaw detection angle and position. In this way, areas other than the pipeline and cable pipeline should be inspected as much as possible, and blind spots in flaw detection are reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0022] like Figure 1-4 As shown, a support frame for a pipeline electromagnetic ultrasonic flaw detection device includes a mounting frame 1 in a ring structure. The mounting frame 1 can be adapted to the DIO1000SFE model portable phased array ultrasonic flaw detector. The mounting frame 1 uses screws to fix the probe. A first cloth belt 2 and a second cloth belt 3 are fixed on both sides of the mounting frame 1 respectively. A steel ring 4 is fixed on the end of the first cloth belt 2 away from the mounting frame 1. The second cloth belt 3 passes through the end of the steel ring 4 away from the mounting frame 1. A threaded tube 5 is installed through the side of the steel ring 4 away from the first cloth belt 2. The central axis of the threaded tube 5 coincides with the central axis of the steel ring 4. A locking bolt 6 is installed axially in the threaded tube 5. One end of the locking bolt 6 extends into the steel ring 4. Before departure, fully charge the portable phased array ultrasonic flaw detector, pass the probe part through the mounting frame 1 and fix it with screws. When inspecting pipelines, carry the portable phased array ultrasonic flaw detector with you. When the second threaded pipe is tightened, the first threaded pipe 5 is tightened, and the second threaded pipe 5 is tightened, so that the second threaded pipe 5 is tightened.

[0023] Among them, the first cloth belt 2 and the second cloth belt 3 can both be made of thicker nylon fabric, which is wear-resistant and not easily deformed or shrunk when exposed to water. The first cloth belt 2 and the second cloth belt 3 have a width greater than 5 cm. After being attached to the outer wall of the pipe, they can be flattened and not easily skewed.

[0024] This portable phased array ultrasonic flaw detector has an operating frequency of 50-60Hz, an operating voltage of AC 100-120V, a pulse repetition frequency of 20kHz, and three optional operating modes: adjustable square wave, negative spike square wave, and burst pulse.

[0025] like Figure 1 and Figure 3 As shown, a leather strip 7 is axially sewn on the outside of the second cloth tape 3. The width of the leather strip 7 is greater than the outer diameter of the locking bolt 6. After the locking bolt 6 rotates forward, the leather strip 7 is squeezed and then pressed against the second cloth tape 3. The leather strip 7 is used to protect the second cloth tape 3 and prevent the locking bolt 6 from directly wearing the second cloth tape 3.

[0026] like Figure 1 and Figure 3As shown, one end of the second cloth belt 3 passing through the steel ring 4 is fixed with an outer sheath 8, and the outer sheath 8 can be made of stainless steel. The outer sheath 8 supports and keeps one end of the second cloth belt 3 flat, and one end of the second cloth belt 3 can pass straight through the steel ring 4 to prevent the end of the second cloth belt 3 from tilting up and blocking the steel ring 4, and can drive one end of the second cloth belt 3 to fall naturally and tighten quickly.

[0027] like Figure 2 and Figure 4 As shown, a handle 9 is fixed to the end of the locking bolt 6 away from the steel ring 4. Holding the handle 9 by hand makes it easy to rotate the locking bolt 6, and keeps a safe distance from the steel ring 4 to prevent the locking bolt 6 from being completely immersed in the steel ring 4.

[0028] like Figure 2 and Figure 4 As shown, a steel plate 10 is integrally installed on the inner side of the steel ring 4 opposite to the locking bolt 6. The diameter of the steel plate 10 is larger than the outer diameter of the locking bolt 6. The steel plate 10 is used to support the locking bolt 6, thereby increasing the area of the steel ring 4 cooperating with the locking bolt 6 to clamp the second cloth tape 3, thereby improving the clamping effect.

[0029] like Figure 2 and Figure 4 As shown, a circular groove 11 is provided in the middle of the steel plate 10 near the threaded tube 5. The diameter of the circular groove 11 is larger than the outer diameter of the locking bolt 6. After the locking bolt 6 squeezes the second cloth tape 3, the second cloth tape 3 partially extends into the circular groove 11, which can increase the axial support area of the second cloth tape 3 and the steel plate 10 on the second cloth tape 3, thereby improving the firmness of the clamping of the second cloth tape 3.

[0030] The working principle of the utility model is as follows: when inspecting pipelines, carry a portable phased array ultrasonic flaw detector with you, stick the probe to the position of the pipeline to be inspected, and then clamp the pipeline from both sides with the first cloth tape 2 and the second cloth tape 3 respectively, pass one end of the second cloth tape 3 through the steel ring 4 until it is tightened, and then rotate the locking bolt 6 forward along the threaded tube 5 to extend into the interior of the steel ring 4, so that one end of the locking bolt 6 cooperates with the steel ring 4 to clamp the second cloth tape 3, and lock the first cloth tape 2 and the second cloth tape 3 under the action of friction, thereby restraining the probe to the outside of the pipeline. Even if there is a cable pipeline at this position, the first cloth tape 2 and the second cloth tape 3 can cover the cable pipeline more softly, reduce the degree of warping of the support frame outside the pipeline, and facilitate the probe to stick to the outer wall of the pipeline.

[0031] After the flaw detection is completed, the locking bolt 6 can be reversed to loosen the second cloth tape 3, so that the first cloth tape 2 and the second cloth tape 3 can be pulled to rotate the probe and freely adjust the flaw detection angle and position. In this way, all areas outside the pipeline and cable pipeline should be inspected to reduce the blind spots of flaw detection.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
