DETAILED DESCRIPTION

[0022] The specific embodiments of the present disclosure will be described in detail hereinafter with reference to the drawings. It should be understood that the specific embodiments described herein are merely illustrative and explanatory and are not intended to limit the present disclosure.

[0023] In the present disclosure, the positional words such as "inner, outer" used herein refer to the inner and outer with respect to the outline of the component or structure itself, and "first, second" and the like are used to distinguish one element from another element and do not have sequential and important meanings, and in addition, the same reference numerals in different reference drawings represent the same elements.

[0024] The present disclosure provides a pipe thickness gauge, with reference to Figures 1 to 4As shown, the pipeline thickness gauge comprises a mounting mechanism 1, a measuring mechanism 2 and a controller 3, wherein the mounting mechanism 1 comprises a clamping assembly 110 for clamping the outer sidewall of the pipeline 4 and a telescopic rod assembly 120 connected to the clamping assembly 110, the telescopic rod assembly 120 extends along the length direction of the pipeline 4 and can be telescoped along the length direction of the pipeline 4; the measuring mechanism 2 comprises a mounting seat 210, a connecting assembly 220 and an ultrasonic probe 230, the mounting seat 210 is connected to the telescopic rod assembly 120, the connecting assembly 220 is connected to the mounting seat 210 and the ultrasonic probe 230, and the ultrasonic probe 230 is used to adhere to the outer sidewall of the pipeline 4; the controller 3 is connected to the mounting seat 210, and the controller 3 is electrically connected to the ultrasonic probe 230 and can control the telescopic rod assembly 120 to telescope to drive the measuring mechanism 2 to move along the length direction of the pipeline 4.

[0025] Through the above technical solution, that is, the pipeline thickness gauge provided by the present disclosure, when the sidewall thickness of the pipeline 4 is measured by the pipeline thickness gauge, the clamping assembly 110 in the mounting mechanism 1 can be clamped to the outer sidewall of the pipeline 4, the controller 3 can be installed on the mounting seat 210, and the ultrasonic probe 230 can be adhered to the outer sidewall of the pipeline 4, then the telescopic rod assembly 120 can be controlled to telescope by operating the controller 3, in the telescoping process of the telescopic rod assembly 120, the whole measuring mechanism 2 will be driven to move along the length direction of the pipeline 4, in this process, the ultrasonic probe 230 will also move while adhering to the outer sidewall of the pipeline 4, and in the moving process, the thickness of different positions of the pipeline 4 is measured, thereby the thickness of multiple continuous positions of the pipeline 4 can be obtained, and the telescopic rod assembly 120 can be controlled by the controller 3 to automatically measure throughout the process, thereby the number of manual movement of the ultrasonic probe 230 by personnel can be reduced, and the measurement steps can be simplified.

[0026] It should be noted that the method of measuring the thickness of the pipeline by the ultrasonic probe 230 mentioned in the above embodiment is a well-known common sense, and the present disclosure will not be described in detail here. In addition, the controller 3 can also adopt any instrument that can control the telescopic rod assembly 120 to telescope and can control the ultrasonic probe 230 to measure the thickness of the pipeline, for example, the controller 3 can adopt the control method widely existing in the prior art such as PLC or DCS, or can adopt the wireless control method such as remote control computer, and the present disclosure does not make specific limitation here.

[0027] In addition, the telescoping of the telescopic rod assembly 120 can also be manually controlled, for example, the staff can push the mounting seat 210 to move along the length direction of the pipeline 4, and then the thickness of the specified position of the pipeline 4 can also be measured by the ultrasonic probe 230, and the present disclosure does not make specific limitation here.

[0028] In addition, the clamping assembly 110 mentioned in the above embodiment can also include any suitable structure capable of clamping the outer wall of the pipeline 4, and the present disclosure will be described in detail below. Therefore, no more details will be provided here.

[0029] In some embodiments, as shown in Figures 1 to 4 The connecting assembly 220 includes an extension rod 221 and a clamp 222. The extension rod 221 is connected to the mounting base 210, and the clamp 222 is connected to the extension rod 221 and the ultrasonic probe 230. In this way, the extension rod 221 can extend from the mounting base 210 to the vicinity of the outer wall of the pipeline 4, and the clamp 222 can be used to fix the ultrasonic probe 230. Thus, when the telescopic rod assembly 120 is controlled to extend or retract by the controller 3, the extension rod 221 and the clamp 222 can move along the length direction of the pipeline 4 together with the mounting base 210, and then the ultrasonic probe 230 can be used to measure the thickness of the outer wall of the pipeline 4. After the measurement is completed, the ultrasonic probe 230 can be quickly disassembled by unlocking the clamp 222. In this way, the ultrasonic probe 230 can be tightly connected by the clamp 222 during the measurement to ensure stable measurement, and the ultrasonic probe 230 can be disassembled from the clamp 222 after the measurement is completed, which is convenient for calibrating the disassembled ultrasonic probe 230.

[0030] In addition, the extension direction of the extension rod 221 mentioned in the above embodiment can be any suitable direction according to actual conditions, as long as one end of the extension rod 221 can be close to the outer wall of the pipeline 4. For example, as shown in Figure 1 The extension rod 221 can extend in the vertical direction along the drawing direction of Figure 1 , or in an embodiment not shown in the figure, the extension rod 221 can extend obliquely towards the outer wall of the pipeline 4, which is not limited in the present disclosure.

[0031] In some embodiments, as shown in Figures 1 to 4 The number of clamping assemblies 110 is two, and the two clamping assemblies 110 are arranged at intervals along the length direction of the pipeline 4. The two clamping assemblies 110 are respectively located on opposite sides of the mounting base 210 along the length direction of the pipeline 4. The telescopic rod assembly 120 is two, and the two telescopic rod assemblies 120 are respectively connected to the opposite sides of the mounting base 210 and are connected to the two clamping assemblies 110 one by one. In this way, when the thickness of the outer wall of the pipeline 4 needs to be measured, the two clamping assemblies 110 can be clamped at different positions along the length direction of the pipeline 4, respectively, i.e. Figure 1As shown in the effect, each clamping assembly 110 is connected to the mounting base 210 through a telescopic rod assembly 120. In this connection mode, the joint clamping of the two clamping assemblies 110 can make the pipe thickness gauge as a whole more stably connected to the pipe 4, thereby improving the accuracy of the numerical value of the ultrasonic probe 230 in the process of measuring the pipe wall thickness. In addition, the two sets of telescopic rod assemblies 120 can also cooperate with each other, that is, it can be understood that in Figure 1 In the direction of the drawing, when the measuring mechanism 2 moves to the left as a whole for measurement, the telescopic rod assembly 120 on the left can be retracted, and the telescopic rod assembly 120 on the right can be extended. Conversely, when the measuring mechanism 2 moves to the right as a whole for measurement, the telescopic rod assembly 120 on the right can be retracted, and the telescopic rod assembly 120 on the left can be extended. The two groups of telescopic rod assemblies 120 can then be used to cooperate with each other to move the measuring mechanism 2. The above method not only improves the stability of clamping the pipe 4, but also improves the stability of the process of moving the measuring mechanism 2, so that a more accurate thickness value of the pipe 4 can be obtained through the ultrasonic probe 230.

[0032] It should be noted that the telescopic rod assembly 120 mentioned in the above embodiment can be connected using any retractable structure. For example, the telescopic rod assembly 120 can use any suitable method such as an electric push rod, a hydraulic cylinder with a push rod, or a pneumatic cylinder with a push rod. This disclosure will be elaborated in detail below and will not be elaborated here.

[0033] In some embodiments, reference Figures 1 to 4 As shown, the telescopic rod assembly 120 includes a plurality of electric push rods arranged side by side. In this way, the electric push rods have the advantages of precise control, easy installation and strong environmental adaptability, such as Figure 3 As shown, each group of telescopic rod assemblies 120 can be respectively arranged with two side-by-side electric push rods. When the telescopic rod assembly 120 is extended or retracted, the two electric push rods can be respectively connected to the mounting base 210 and the clamping assembly 110 to extend or retract together. Under this connection method, multiple electric push rods can improve the stability of the measuring mechanism 2 in the movement along the length direction of the pipeline 4. In addition, it should be noted that the number of two electric push rods shown in the figure is only exemplary. In embodiments not shown in the figure, the electric push rods can also be arranged three, four or more side by side, and the present disclosure does not make specific limitations on this.

[0034] In some embodiments, reference Figures 1 to 4As shown, the clamping assembly 110 includes a mounting frame 111, clamping pieces 112 and an adjusting piece 113, wherein the mounting frame 111 is connected to the telescopic rod assembly 120; the clamping pieces 112 are two in number and are connected to the mounting frame 111 at intervals; the adjusting piece is connected to the mounting frame 111 and the two clamping pieces 112, and the two clamping pieces 112 can be adjusted to approach or move away from each other through the adjusting piece 113. In this way, when the pipe 4 is clamped by the clamping assembly 110, the distance between the two clamping pieces 112 can be adjusted by the adjusting piece 113, so that the two clamping pieces 112 can be clamped to the side wall of the pipe 4, thereby facilitating the subsequent thickness measurement of the side wall of the pipe 4 by the ultrasonic probe 230. The adjusting piece 113 can be any suitable piece that can adjust the distance between the two clamping pieces 112, for example, the adjusting piece 113 can be a spring connected between the two clamping pieces 112, and the distance between the two clamping pieces 112 can be adjusted by the extension and contraction of the spring, or it can also be other devices that can adjust the distance between the two clamping pieces 112. The present disclosure will be described in detail below, and no further description is given here.

[0035] In some embodiments, with reference to Figures 1 to 4 As shown, the adjusting piece 113 includes a threaded rod 1131 and a nut 1132, wherein one of the clamping pieces 112 is threaded through the threaded rod 1131, and the nut 1132 is screwed onto the threaded rod 1131, used to fit the clamping piece 112 threaded through the threaded rod 1131 when the two clamping pieces 112 clamp the pipe 4. In this way, when it is necessary to clamp the pipe 4 by the two clamping pieces 112, one of the clamping pieces 112 can be first fitted to the outer side wall of the pipe 4, and then the position of the other clamping piece 112 relative to the threaded rod 1131 can be adjusted, that is Figure 2 As shown, the left clamping piece 112 can be fixedly connected to the mounting frame 111 and connected to one end of the threaded rod 1131, and the right clamping piece 112 can be threaded through the threaded rod 1131 and can move along the extension direction of the threaded rod 1131. After the movable clamping piece 112 is also fitted to the outer side wall of the pipe 4, the end face of the nut 1132 can be fitted to the outer side wall of the right clamping piece 112 by tightening the nut 1132, thereby limiting the right clamping piece 112. At this time, the two clamping pieces 112 can be stably fitted to the outer side wall of the pipe 4 to fix the pipe thickness gauge as a whole relative to the pipe 4, thereby facilitating the subsequent measurement by the ultrasonic probe 230.

[0036] In some embodiments, with reference to Figure 2As shown, the clamping member 112 comprises a clamping portion 1121 which is capable of abutting the outer sidewall of the pipe 4 when the clamping member 112 clamps the pipe 4. In this way, when the clamping member 112 clamps the pipe 4, the clamping portion 1121 can abut the outer sidewall of the pipe 4 to at least partially embrace the pipe 4, for example, as shown in Figure 2 As shown, the clamping portion 1121 can be an arc-shaped plate body which is capable of abutting the outer sidewall of the pipe 4, and when two arc-shaped plate bodies clamp the pipe 4, the inner sidewall of the arc-shaped plate body can abut the outer sidewall of the pipe 4 to at least partially embrace the pipe 4.

[0037] Further, in order to improve the stability of the clamping member 112 during clamping of the pipe 4, as shown in Figure 2 As shown, the side of the clamping portion 1121 which abuts the outer sidewall of the pipe 4 can be provided with an anti-skid member 1122. In this way, the anti-skid member 1122 can prevent the pipe 4 from rotating or moving relative to the clamping member 112, thereby improving the stability of the clamping member 112 when clamping the pipe 4, and the anti-skid member 1122 can also be made of any anti-skid material in the prior art, for example, the anti-skid member 1122 can be any anti-skid rubber pad, silicone pad or polyurethane pad, and the present disclosure does not make specific limitations in this regard.

[0038] In some embodiments, as shown in Figures 1 to 4 As shown, the measuring mechanism 2 further comprises a locking member 240 connected to the mounting seat 210, and the locking member 240 is used to lock the controller 3 when the controller 3 is connected to the mounting seat 210. In this way, the locking member 240 can stably lock the controller 3 on the mounting seat 210, thereby preventing the controller 3 from being separated from the mounting seat 210 when measuring the thickness of the pipe 4, as shown in Figure 3 As shown, the locking member 240 can be four clamping blocks respectively arranged on the mounting seat 210 and located at the four corners of the controller 3, and at least two adjacent clamping blocks can be in sliding connection with the mounting seat 210, that is, a clamping structure similar to a mobile phone holder can be understood, and when it is necessary to lock and fix the controller 3, the controller 3 can be placed on the mounting seat 210 by manually actuating the movable clamping blocks, and then the movable clamping blocks are abutted to the controller 3, thereby achieving the locking and fixing of the controller 3.

[0039] In some embodiments, as shown in Figures 1 to 4As shown, the controller 3 is wired to the ultrasonic probe 230, and the measuring mechanism 2 further comprises a fixing member 250 connected to the extension rod 221 for fixing the wire harness. In this way, when the controller 3 is wired to the ultrasonic probe 230, the wire harness can be fixed on the extension rod 221 by the fixing member 250, so that the ultrasonic probe 230 will not be affected by the messy wire harness and can stably measure the thickness of the pipe 4, i.e., it can be referred to as Figure 1 As shown, after the wire harness is connected to the output end of the controller 3, it can be connected to the ultrasonic probe 230 along the extension direction of the extension rod 221, and the middle section of the wire harness can be buckled on the outer side wall of the extension rod 221 by the fixing member 250 to achieve the fixation of the wire harness, and the fixing member 250 can also be any structure capable of fixing the wire harness, for example, the fixing member 250 can adopt the structure of a wire harness fixing device, a buckle or a bandage widely existing in the prior art, and the present disclosure does not make specific limitations thereon.

[0040] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above-described embodiments, and various simple modifications can be made to the technical solutions of the present disclosure within the technical concept of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0041] In addition, it should be noted that each specific technical feature described in the above-described specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present disclosure will not make further descriptions on various possible combination manners.

[0042] In addition, various different embodiments of the present disclosure can also be combined in any manner as long as they do not deviate from the idea of the present disclosure, and they should also be considered as disclosed by the present disclosure.
