Description

TECHNICAL FIELD

[0001] The utility model relates to a welding seam detection technical field, especially a kind of nondestructive testing device for pipeline welding seam detection. BACKGROUND

[0002] Nondestructive testing device for pipeline welding seam detection refers to the equipment for detecting the internal or surface defects of welding seam without damaging or affecting the performance and structure of pipeline welding seam, usually including radiographic testing device, ultrasonic testing device, magnetic particle testing device and the like.

[0003] The existing ultrasonic testing device has high detection sensitivity, can detect small defects on the surface and near the surface, and the ultrasonic testing device is small in size, significantly improves portability, so that workers can easily operate whether they are in the field construction site or the narrow interior of industrial equipment, effectively expands the detection application scenarios, and greatly improves the use flexibility of ultrasonic testing device under complex working conditions.

[0004] However, in actual application scenarios, the connecting line on the existing ultrasonic testing device is a fixed-length linear structure, so that the connecting line cannot be effectively stored or the length of the connecting line cannot be adjusted during use of the detection device, so that the connecting line is easily entangled with debris in the working environment during use, thereby affecting the use of the detection device and being not conducive to improving the flexibility of the detection device.

[0005] Therefore, the present application provides a nondestructive testing device for pipeline welding seam detection to meet the needs. UTILITY MODEL CONTENTS

[0006] The utility model aims at solving the shortcomings in the prior art and provides a nondestructive testing device for pipeline welding seam detection.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a nondestructive testing device for pipeline welding seam detection, comprising an ultrasonic testing instrument, further comprising:

[0008] The winding assembly is arranged on the top of the ultrasonic testing instrument, and the winding assembly comprises a fixing plate fixed on the top of the ultrasonic testing instrument, a winding rod fixedly connected to the fixing plate, two winding rods arranged on the fixing plate, two winding rods vertically distributed on the fixing plate, a connecting line arranged on the two winding rods, and a probe fixedly connected to one end of the connecting line away from the ultrasonic testing instrument.

[0009] A limiting component is arranged on one side of the winding component and is used to prevent the connecting wire from being separated from the winding rod, the limiting component comprises a movable plate arranged on the winding rod away from one end of the fixed plate, one end of the winding rod close to the movable plate is fixedly connected with an elastic plate, one end of the elastic plate close to the movable plate is fixedly connected with a buckle, one side of the movable plate close to the buckle is provided with a clamping groove, and the elastic plate is clamped with the movable plate through the buckle and the clamping groove.

[0010] Further, one side of the probe is provided with a telescopic rod, and a rotary connecting piece is arranged between the telescopic rod and the probe.

[0011] The beneficial effect of the above further scheme is that the telescopic rod can rotate on the probe through the rotary connecting piece, thereby adjusting the angle between the probe and the telescopic rod, which is beneficial to improve the flexibility of the probe.

[0012] Further, one end of the telescopic rod close to the rotary connecting piece is fixedly connected with a threaded column, and the telescopic rod is threadedly connected with the rotary connecting piece through the threaded column.

[0013] The beneficial effect of the above further scheme is that such a connection mode facilitates the disassembly of the rotary connecting piece and facilitates the classified storage of the probe and the telescopic rod.

[0014] Further, as shown in the figure, the inside of the rotary connecting piece close to the probe is provided with a torsion spring.

[0015] The beneficial effect of the above further scheme is that when the rotary connecting piece rotates, the torsion spring keeps the angle between the probe and the rotary connecting piece fixed through automatic torsion, thereby ensuring the stability of the probe during use.

[0016] Further, a rubber pad is arranged on the winding rod.

[0017] The beneficial effect of the above further scheme is that the rubber pad provides a buffer space for the winding rod and the connecting wire, avoids the over-tight winding of the connecting wire on the winding rod, and prevents the connecting wire from being broken.

[0018] Further, one side of the movable plate close to the ultrasonic detector is fixedly connected with a sliding block, and the movable plate is slidingly connected with the ultrasonic detector through the sliding block.

[0019] The beneficial effect of the above further scheme is that the movable plate slides on the ultrasonic detector along the sliding groove through the sliding block, thereby limiting the movement path of the movable plate and preventing the movable plate from deviating during movement.

[0020] Further, one side of the ultrasonic detector is fixedly connected with a handle.

[0021] The beneficial effects of adopting the above-mentioned further solution are: the handle makes it easier to carry the ultrasonic detector and improve its portability.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. By setting up a winding component, the connecting wire is pulled to rotate and wind along two arrays of winding rods distributed on the fixed plate, increasing the winding path length and accommodating longer connecting wires. Before using the probe, the length of the connecting wire wound on the winding rod can be flexibly adjusted according to the on-site working conditions, effectively preventing the cable from snagging on debris. This solves the pain point of traditional detection devices being difficult to store and adjust the cable length, significantly improving the flexibility and convenience of detection operations.

[0024] 2. By setting a limiting component, the movable plate is pushed towards the winding rod. When the movable plate comes into contact with the elastic plate, due to the elasticity of the elastic plate, it is compressed into the groove of the movable plate after being squeezed by the movable plate. As the movable plate continues to advance, when the buckle and the locking groove are precisely aligned, the elastic plate uses its own elasticity to push the buckle into the locking groove, thereby firmly fixing the movable plate on the winding rod, effectively preventing the connecting wire from detaching from the winding rod, maintaining a constant cable length, and ensuring the stability of the testing device during use.

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] As shown in Figures 1-5 The present application provides a technical scheme: a nondestructive testing device for pipeline weld detection, comprising an ultrasonic detector 1, further comprising:

[0036] As shown in Figures 1-4 The winding assembly 2 is placed on the top of the ultrasonic detector 1, the winding assembly 2 comprises a fixed plate 21 fixed on the top of the ultrasonic detector 1, the fixed plate 21 is fixedly connected with a winding rod 22, the number of the winding rod 22 arranged on the fixed plate 21 is two, the two winding rods 22 are vertically distributed on the fixed plate 21, the two winding rods 22 are provided with a connecting line 23, and the end of the connecting line 23 away from the ultrasonic detector 1 is fixedly connected with a probe 24;

[0037] As shown in Figures 3-4As shown, the limiting component 3 is placed on one side of the winding component 2 and is used to prevent the connecting wire 23 from separating from the winding rod 22. The limiting component 3 includes a movable plate 31 disposed on the winding rod 22 away from the fixed plate 21. An elastic plate 32 is fixedly connected to the end of the top winding rod 22 near the movable plate 31. A buckle 33 is fixedly connected to the end of the elastic plate 32 near the movable plate 31. A snap-fit ​​groove 34 is opened on the side of the movable plate 31 near the buckle 33. The elastic plate 32 is snapped into the movable plate 31 through the buckle 33 and the snap-fit ​​groove 34. By connecting the two ends of the connecting wire 23 to the ultrasonic detector 1 and the probe 24 respectively, data communication between the probe 24 and the ultrasonic detector 1 is ensured. Pulling the connecting wire 23 to rotate along the two winding rods 22, the connecting wire 23 is wound around the winding rods 22. Since the two winding rods 22 are arrayed on the fixed plate 21, the distance of the connecting wire 23 during winding is increased, so that the detection device can The device is designed to accommodate longer connecting cables 23. Before using the probe 24, the length of the connecting cable 23 wound around the winding rod 22 can be adjusted according to the working environment to prevent the connecting cable 23 from getting tangled in debris. This solves the problem of not being able to effectively store or adjust the length of the connecting cable 23 during the use of the detection device, thus improving the flexibility of the detection device. Furthermore, by pushing the movable plate 31 towards the winding rod 22, the movable plate 31 comes into contact with the elastic plate 32. Due to the elasticity of the elastic plate 32, it is compressed by the movable plate 31 and squeezed into the groove of the movable plate 31. As the movable plate 31 continues to move, the buckle 33 aligns with the locking groove 34. The elastic plate 32 then pushes the buckle 33 into the locking groove 34 through its own elasticity, fixing the movable plate 31 onto the winding rod 22. This prevents the connecting cable 23 from separating from the winding rod 22, maintains the length of the connecting cable 23, and ensures the stability of the detection device during use.

[0038] Furthermore, such as Figure 5 As shown, a telescopic rod 25 is provided on one side of the probe 24, and a rotating connector 26 is provided between the telescopic rod 25 and the probe 24. The rotating connector 26 is rotatably connected to the probe 24. By adjusting the length of the telescopic rod 25, the telescopic rod 25 and the probe 24 are sent into the interior of the pipe to inspect the weld seam inside the pipe, thus improving the practicality of the inspection device. Furthermore, by fixing two side plates to the probe 24 and installing a rotating shaft between the side plates and the rotating connector 26, the rotating connector 26 can rotate on the probe 24 through the rotating shaft, ensuring that the telescopic rod 25 can rotate on the probe 24 through the rotating connector 26, thereby adjusting the angle between the probe 24 and the telescopic rod 25, which helps to improve the flexibility of the probe 24.

[0039] Furthermore, such as Figure 5As shown, the telescopic rod 25 is fixedly connected with a threaded column 27 at one end close to the rotary connecting piece 26, and the telescopic rod 25 is threadedly connected with the rotary connecting piece 26 through the threaded column 27. A threaded groove matched with the threaded column 27 is formed in the rotary connecting piece 26, and the telescopic rod 25 is threadedly installed on the rotary connecting piece 26 by rotating the threaded column 27. Such a connecting mode facilitates the disassembly and assembly of the rotary connecting piece 26 and facilitates the classified storage of the probe 24 and the telescopic rod 25.

[0040] Further, as shown in Figure 5 The rotary connecting piece 26 is provided with a torsion spring 28 at the side close to the probe 24. A notch matched with the torsion spring 28 is formed in the probe 24 and the rotary connecting piece 26, so as to fix the torsion spring 28 between the rotary connecting piece 26 and the probe 24. After the rotary connecting piece 26 is rotated, the torsion spring 28 keeps the angle between the probe 24 and the rotary connecting piece 26 fixed by the automatic torsion, thereby ensuring the stability of the probe 24 during use.

[0041] Further, as shown in Figure 4 The winding rod 22 is sleeved with a rubber pad 29. The rubber pad 29 is used to avoid the contact between the connecting line 23 and the diameter of the winding rod 22. Since the rubber pad 29 has elasticity, the rubber pad 29 provides a buffer space for the winding rod 22 and the connecting line 23, thereby avoiding the over-tight winding of the connecting line 23 on the winding rod 22 and preventing the breakage of the connecting line 23.

[0042] Further, as shown in Figure 3 The movable plate 31 is fixedly connected with a sliding block 35 at the side close to the ultrasonic detector 1. The movable plate 31 is slidably connected with the ultrasonic detector 1 through the sliding block 35. A sliding groove matched with the sliding block 35 is formed in the ultrasonic detector 1, and the movable plate 31 slides along the sliding groove on the ultrasonic detector 1 through the sliding block 35. The movement path of the movable plate 31 is limited, thereby preventing the movable plate 31 from deviating during movement.

[0043] Further, as shown in Figure 3 The ultrasonic detector 1 is fixedly connected with a handle 36 at one side. The handle 36 is held to facilitate the carrying of the ultrasonic detector 1, thereby improving the portability of the ultrasonic detector 1.
