DETAILED DESCRIPTION
[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0028] like Figure 1-4 As shown, the utility model provides a device for measuring the position of the butt weld of a high-temperature pipeline of a thermal power unit, comprising a welding pipe 1, a bracket 2 and an ultrasonic generator 3, a surface of the bracket 2 is provided with a limiting structure 4, and a surface of the bracket 2 is provided with a protective structure 5.
[0029] The specific settings and functions of the limiting structure 4 and the protective structure 5 are described in detail below.
[0030] like Figure 2 and Figure 3As shown, the limiting structure 4 includes an electric push rod 41, which is fixedly connected to the bracket 2, and a push plate 42 is fixedly connected to the output end of the electric push rod 41. The surface of the push plate 42 is rotatably connected to a rotating wheel 43, and the rotating wheel 43 abuts against the outer wall of the welding pipe 1. A screw rod 44 is rotatably connected in the bracket 2, and the ultrasonic generator 3 is detachably mounted on one end of the screw rod 44. A telescopic rod 45 is fixedly connected to the surface of the push plate 42, and one end of the telescopic rod 45 is fixedly connected to the bracket 2. The telescopic rod 45 can limit the moving path of the push plate 42 to prevent the push plate 42 from being pushed. The rotation of plate 42 causes the rotating wheel 43 to tilt, and a clamping plate 46 is fixedly connected to the surface of the bracket 2, and a scraper 47 is slidably connected to the inner wall of the clamping plate 46, and a positioning rod 48 is fixedly connected to the surface of the scraper 47. The scraper 47 will flatten the thicker coupling agent on the outer wall of the welding pipe 1, so as to evenly apply the coupling agent, and a spring 49 is fixedly connected to the surface of the scraper 47, and one end of the spring 49 away from the scraper 47 is fixedly connected to the bracket 2. The scraper 47 can use the tension of the spring 49 to make the positioning rod 48 press against the outer wall of the welding pipe 1.
[0031] like Figure 3 and Figure 4 As shown, the protective structure 5 includes a traction rope 51, one end of which is fixedly connected to the bracket 2, and the other end of the traction rope 51 is fixedly connected to a protective cover 52. A fixing ring 53 is fixedly connected to the surface of the bracket 2, and the size of the fixing ring 53 matches the size of the protective cover 52. A positioning block 54 is fixedly connected to the surface of the bracket 2, and a groove 56 is provided on the surface of the positioning block 54. A protrusion 55 is fixedly connected to the outer wall of the protective cover 52, and the size of the protrusion 55 matches the size of the groove 56. When the groove 56 is engaged with the protrusion 55, the groove 56 reaches the position of limiting the protrusion 55, thereby limiting the position of the protective cover 52.
[0032] The overall working principle is that when it is necessary to inspect the butt weld of the high-temperature pipeline of the thermal power unit, the coupling agent is first applied to the weld, and then the bracket 2 is moved. The movement of the bracket 2 will drive the electric push rod 41 to move, and the movement of the electric push rod 41 will drive the push plate 42 to move. The movement of the push plate 42 will drive the rotating wheel 43 to move. When the welding pipe 1 is located between the two push plates 42, the electric push rod 41 is turned on, and the output end of the electric push rod 41 extends to drive the push plate 42 to move. The movement of the push plate 42 will cause the rotating wheel 43 to abut against the outer wall of the welding pipe 1. In this process, the telescopic rod 45 can limit the moving path of the push plate 42 to prevent the push plate 42 from rotating and causing the rotating wheel 43 to tilt. The situation occurs, and then the screw rod 44 is rotated. The screw rod 44 will drive the ultrasonic generator 3 to move with the help of the thread, so that the ultrasonic generator 3 is against the coupling agent, and the scraper 47 will use the tension of the spring 49 to make the positioning rod 48 against the outer wall of the welding pipe 1. Then the bracket 2 is rotated, and the rotating wheel 43 will rotate along the outer wall of the welding pipe 1. At this time, the positioning rod 48 can limit the distance between the scraper 47 and the welding pipe 1. The scraper 47 will flatten the thicker coupling agent on the outer wall of the welding pipe 1, so as to evenly apply the coupling agent. As the bracket 2 continues to move, the ultrasonic generator 3 can continue to detect the weld, and can continue to align with the weld during the detection process to ensure the detection accuracy.
[0033] When no detection is performed, the protective cover 52 is moved. The protective cover 52 moves and inserts into the inner wall of the fixing ring 53. At this time, the ultrasonic generator 3 is located in the protective cover 52. The protective cover 52 can shield and protect the ultrasonic generator 3 to prevent the ultrasonic generator 3 from being damaged during the movement of the ultrasonic generator 3. Then, the protective cover 52 is rotated. The rotation of the protective cover 52 drives the protrusion 55 to rotate. When the protrusion 55 is aligned with the groove 56, the protective cover 52 is moved to make the protrusion 55 slide into the inner wall of the groove 56. When the groove 56 is engaged with the protrusion 55, the groove 56 reaches the position of limiting the protrusion 55, thereby limiting the position of the protective cover 52.
[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
