Description

Technical Field

[0001] This utility model belongs to the field of non-destructive testing technology for pipes, specifically relating to an integrated ultrasonic testing device for pipe fittings that integrates eddy current testing and ultrasonic testing functions. Background Technology

[0002] In existing technologies, non-destructive testing of pipes typically includes two methods: eddy current testing and ultrasonic testing. In traditional testing equipment, eddy current testing devices and ultrasonic testing devices are usually set up and installed independently. When both tests are required, operators need to move the pipe back and forth between the two devices and repeatedly reposition it. This is not only time-consuming and labor-intensive, but also prone to surface damage or positioning errors due to repeated handling, affecting testing accuracy and efficiency.

[0003] Therefore, there is an urgent need for an integrated testing device that can integrate two testing functions, reduce the number of times pipes are handled, and improve testing efficiency. Utility Model Content

[0004] The technical problem solved by this utility model is to provide an integrated ultrasonic testing device for non-destructive testing of pipe fittings, so as to solve the problems of scattered testing equipment, cumbersome operation and low efficiency in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An integrated ultrasonic testing device for non-destructive testing of pipe fittings includes a frame. An eddy current testing device and an ultrasonic testing device are sequentially arranged longitudinally on the upper part of the frame. Multiple pipe fitting guide frames are mounted on the frame, distributed between and on both sides of the eddy current testing device and the ultrasonic testing device to ensure the pipe fittings are center-aligned. The pipe fittings of the eddy current testing device, the ultrasonic testing device, and the guide frames are center-aligned. The lower parts of both the eddy current testing device and the ultrasonic testing device are connected to the frame via a forward and backward moving mechanism. This mechanism drives the eddy current testing device and the ultrasonic testing device to move laterally, selectively placing one or both devices in a working position.

[0006] Further defining the above solution, the forward and backward moving mechanism includes a fixed base and a movable base. The fixed base is fixedly mounted on the equipment frame, and the movable base is slidably connected to the fixed base via pulleys and slide rails. The slide rails are fixed to the upper surface of the fixed base, and the pulleys are fixed to the lower surface of the movable base. The eddy current flaw detection device or ultrasonic testing device is mounted on the movable base.

[0007] Further defining the above solution, the fixed base is provided with a bearing seat, the bearing seat supports a lead screw, the lower part of the movable base is fixed with a lead screw nut, and the lead screw nut is screwed into the lead screw; one end of the lead screw is connected to a drive device, which is a crank handle or a motor.

[0008] To further define the above solution, both the fixed base and the movable base are provided with positioning seats on their rear sides. The positioning seats are provided with positioning holes, and the movable base is positioned by inserting a positioning pin.

[0009] Further defining the above scheme, the pipe fitting guide frame includes a fixed guide wheel and an adjustable guide wheel. The adjustable guide wheel is hinged to the guide frame via a connecting rod. A push rod is hinged to the other end of the connecting rod, and the other end of the push rod is hinged to the guide frame.

[0010] Further specifying the above solution, the push rod is an electric push rod or a cylinder, which realizes automatic adjustment of the guide wheel spacing to adapt to different pipe diameters.

[0011] Advantages of this utility model compared to the prior art: 1. This solution integrates eddy current testing and ultrasonic testing into the same equipment, enabling the completion of both tests in one go and significantly improving testing efficiency; 2. This solution, through its forward and backward moving mechanism, allows for flexible selection of testing modes to meet single or multiple testing needs; 3. The guide frame structure of this solution is adjustable to adapt to different pipe diameters, improving the versatility of the equipment; 4. This solution has a compact overall structure, is easy to operate, reduces manual intervention, and lowers labor intensity; 5. This solution integrates the control system, enabling synchronized data processing and unified management. Attached Figure Description

[0016] Please see Figure 1-3 The embodiments of this utility model are described in detail below.

[0017] See Figure 1 As shown, the ultrasonic integrated testing equipment for non-destructive testing of pipe fittings provided by this utility model includes a frame 1. Eddy current testing device 2 and ultrasonic testing device 3 are sequentially arranged longitudinally on the upper part of the frame 1. Multiple pipe fitting guide frames 4 are provided on the frame 1, distributed between the two testing devices and on both sides, to ensure that the pipe fittings are aligned at the center.

[0018] The lower parts of the eddy current testing device 2 and the ultrasonic testing device 3 are both connected to the equipment frame 1 through a front-to-back moving mechanism 5. The front-to-back moving mechanism 5 is used to drive the eddy current testing device 2 and the ultrasonic testing device 3 to move laterally, so as to selectively place one or both devices in the pipe passage position.

[0019] See Figure 2 As shown, the forward and backward moving mechanism 5 includes a fixed seat 5-1 and a movable seat 5-2. The fixed seat 5-1 is fixedly mounted on the equipment frame 1. The movable seat 5-2 is slidably connected to the slide rail 5-4 on the fixed seat 5-1 via a pulley 5-3. The slide rail 5-4 is fixed to the upper surface of the fixed seat 5-1, and the pulley 5-3 is fixed to the lower surface of the movable seat 5-2. An eddy current testing device 2 or an ultrasonic testing device 3 is installed on the movable seat 5-2. The fixed seat 5-1 is provided with a lead screw 5-5 supported by a bearing seat 5-7. A lead screw nut 5-6 is fixed to the lower part of the movable seat 5-2. The lead screw nut 5-6 is screwed into the lead screw 5-5. One end of the lead screw 5-5 is driven to rotate by a crank 5-8 or a motor, which drives the movable seat 5-2 to move forward and backward.

[0020] Both the fixed seat 5-1 and the movable seat 5-2 are provided with a positioning seat 5-9 on their rear sides. The positioning seat 5-9 is provided with a positioning hole, and the movable seat 5-2 can be accurately positioned by inserting the positioning pin 5-10.

[0021] See Figure 3 As shown, the pipe fitting guide frame 4 includes a fixed guide wheel 4-1 and an adjustable guide wheel 4-2. The adjustable guide wheel 4-2 is hinged to the guide frame 4 via a connecting rod 4-3. The other end of the connecting rod 4-3 is hinged to a push rod 4-4. The other end of the push rod 4-4 is hinged to the guide frame 4. The push rod 4-4 can be an electric push rod or a cylinder to realize the automatic adjustment of the guide wheel spacing.

[0022] Working principle: During operation, the pipe is guided into the testing area by the pipe fitting guide frame 4. If eddy current and ultrasonic testing are required simultaneously, both devices are in the working position; if only one test is required, the other device is moved out of the working area via a forward and backward movement mechanism. Push rod 4-4 drives adjusting guide wheel 4-2 to accommodate different pipe diameters. The testing data is processed and output by the integrated control system.

[0023] In summary, this utility model has a reasonable structure, is easy to operate, and has a high degree of functional integration. It is suitable for non-destructive testing of various pipe materials and has high practical value and promising prospects for promotion.
