Description

Technical Field

[0001] This utility model relates to the technical field of non-destructive testing devices for steel structure welds, specifically a non-destructive testing device for steel structure welds that can assist in wire take-up. Background Technology

[0002] Non-destructive testing (NDT) devices for steel structure welds refer to equipment and technologies used to detect defects or inhomogeneities in steel structure welds. These devices utilize the properties of sound, light, magnetism, and electricity to detect defects in welds, such as cracks, porosity, and incomplete penetration, without damaging or affecting the performance of the inspected object. They provide information such as the size, location, nature, and quantity of the defects. During the use of NDT devices for steel structure welds, auxiliary wire-receiving structures are required to improve the effectiveness of the testing. For example:

[0003] Chinese Patent Publication No. CN218157883U discloses a non-destructive testing fixture for steel structures, including a display, a non-destructive testing probe, and a first connecting line. A retractable auxiliary testing rod is fitted onto the outer surface of the first connecting line. A portion of the first connecting line inside the retractable auxiliary testing rod is in a retractable spiral shape. One end of the retractable auxiliary testing rod has a flexible bending section, and the non-destructive testing probe is detachably mounted on the flexible bending section. One end of the first connecting line is electrically connected to the display. This utility model, through the design of the first connecting line, the retractable auxiliary testing rod, and the flexible bending section, allows for adjustment of the length of the retractable auxiliary testing rod according to actual needs, enabling non-destructive testing of welds at both high and low points of bridge steel structures over a wide area. It eliminates the need for the operator to bend over or stand on tiptoe during testing, making it more convenient to use.

[0004] The existing technical solutions described above have the following drawbacks:

[0005] 1. When performing non-destructive testing on steel structure welds at different locations, the non-destructive testing probe and the first connecting line are disassembled and replaced with connecting lines of different lengths. In actual use, the purpose of performing non-destructive testing on steel structure welds at different locations is achieved by replacing connecting lines of different lengths. The process is quite cumbersome.

[0006] 2. The protective effect of ordinary steel structure weld non-destructive testing equipment is not good, which can easily cause damage to the steel structure weld non-destructive testing equipment;

[0007] 3. The cleaning of the display screen of the non-destructive testing device for steel structure welds is not convenient enough. Therefore, this utility model provides a non-destructive testing device for steel structure welds that can assist in wire winding to solve the above-mentioned problems. Utility Model Content

[0008] The purpose of this invention is to provide a non-destructive testing device for steel structure welds that can assist in wire retraction, in order to solve the problems mentioned in the background art, which involve disassembling and replacing the non-destructive testing probe with a first connecting wire of different lengths to perform non-destructive testing on steel structure welds at different locations. In actual use, this process of replacing the connecting wire with different lengths to achieve the purpose of non-destructive testing on steel structure welds at different locations is cumbersome. Ordinary non-destructive testing devices for steel structure welds have poor protective effects and are prone to damage. Furthermore, cleaning the display screen of the non-destructive testing device for steel structure welds is not convenient enough.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a non-destructive testing device for steel structure welds that can assist in wire take-up, including a non-destructive testing instrument, a display screen is provided on the middle side of its right end, and a connecting wire is fixedly installed on the lower left side of the non-destructive testing instrument;

[0010] Also includes:

[0011] A sponge pad is movably installed on the outside of the non-destructive testing instrument, and a protective plate is movably installed on the outside of the sponge pad. A limit block is movably installed on the front middle side of the protective plate, and a fixing rod is movably installed on the outside of the limit block. A cleaning structure is fixedly installed on the right side of the non-destructive testing instrument.

[0012] A connecting plate is movably installed on the outer side of the middle of the connecting line, and a probe is provided on the upper left side of the connecting line. A movable block is movably installed on the left side inside the connecting plate, and a limit rod is movably installed on the front left side of the movable block. A movable cylinder is fixedly installed on the right side of the movable block.

[0013] Preferably, the sponge pad and the protective plate are connected by a snap-fit ​​method, and the cross-sectional shape of the sponge pad is a "U" shape.

[0014] Preferably, the cleaning structure includes a mounting plate, which is fixedly installed on the outer right side of the non-destructive testing instrument. A cylinder is fixedly installed on the upper inner side of the mounting plate, and a movable plate is fixedly installed on the left end of the cylinder. A mounting rod is movably installed on the front side of the middle part of the movable plate, and a cleaning cotton is movably installed on the rear side of the mounting rod.

[0015] Preferably, the movable plate and the cleaning cotton are connected by an engaging mechanism, and the movable plate and the mounting plate are connected by a sliding mechanism.

[0016] Preferably, the movable plate and the mounting rod are connected by threads, which also serves to limit the movement of the cleaning cotton.

[0017] Preferably, the limiting block and the fixing rod are connected by a thread, and the fixing rod is symmetrically distributed about the center line of the protective plate.

[0018] Preferably, the movable cylinder and the connecting plate are connected by rotation, and the right end of the movable cylinder has a perforated structure.

[0019] Preferably, the movable block and the connecting plate are connected by rotation, and the vertical cross-section of the movable block is a "T" shaped structure.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the non-destructive testing device for steel structure welds that can assist in wire winding facilitates the assistance in winding the connecting wire, thereby facilitating non-destructive testing at different locations, facilitating the protection of the non-destructive testing device, and facilitating the cleaning of the display screen of the non-destructive testing device.

[0021] 1. By installing the protective plate on the outside of the non-destructive testing instrument, the protective plate is snapped into place on the outside of the non-destructive testing instrument, thereby making the non-destructive testing instrument and the sponge pad fit together. Then, the limiting block is slidably installed on the front middle side of the protective plate. Rotating the fixing rod makes the fixing rod threaded on the front outer side of the protective plate, thereby making the fixing rod threaded on the middle outer side of the limiting block. This facilitates the installation of the protective plate, and the sponge pad installed inside the protective plate protects the non-destructive testing instrument.

[0022] 2. By activating the cylinder, the cylinder drives the moving plate to slide inside the mounting plate, which in turn drives the cleaning cotton to slide inside the mounting plate. This allows the cleaning cotton to wipe the dust off the display screen surface, facilitating dust removal. Then, by rotating the mounting rod, the mounting rod is threaded into the front center of the moving plate, causing the mounting rod to slide forward and separate from the cleaning cotton in the middle. This allows the cleaning cotton to separate from the rear center of the moving plate, facilitating its replacement.

[0023] 3. By rotating the limiting rod, the limiting rod is threaded to the front left side of the movable block, causing the limiting rod to slide to the left side of the movable block. This allows the limiting rod to separate from the left side of the connecting plate. Rotating the movable block causes it to rotate inside the connecting plate on the left side, causing the movable block to drive the movable cylinder to rotate inside the connecting plate. This allows the connecting plate to wind the connecting line. Rotating the limiting rod again causes it to be threaded to the front left side of the movable block, thus threading the limiting rod to the front left side of the connecting plate. This facilitates the limiting of the movable cylinder and makes it easier to take in the connecting line. Attached Figure Description

The protective plate 3 is installed on the outside of the non-destructive testing instrument 1, so that the non-destructive testing instrument 1 and the sponge pad 2 are attached. Then, the limiting block 9 is installed on the front middle side of the protective plate 3. The fixing rod 10 is rotated to connect the fixing rod 10 to the front outer side of the protective plate 3, so that the fixing rod 10 is connected to the middle outer side of the limiting block 9, which facilitates the installation of the protective plate 3. The sponge pad 2 installed inside the protective plate 3 protects the non-destructive testing instrument 1. The cleaning structure is activated to wipe the dust on the surface of the display screen 4, which facilitates the cleaning of the display screen 4.

[0034] The connecting plate 8 is movably installed on the outer side of the middle of the connecting line 7, and a probe is provided on the upper left side of the connecting line 7. A movable block 15 is movably installed on the left side inside the connecting plate 8, and a limit rod 16 is movably installed on the front left side of the movable block 15. A movable cylinder 14 is fixedly installed on the right side of the movable block 15. Rotating the limit rod 16 connects it to the front left side of the movable block 15, causing the limit rod 16 to slide to the left on the front side of the movable block 15, thereby allowing the limit rod 16 to connect... Separate the left side of plate 8, rotate movable block 15 so that movable block 15 rotates inside the left side of connecting plate 8, thereby causing movable block 15 to drive movable cylinder 14 to rotate inside connecting plate 8, thereby causing connecting plate 8 to wind connecting line 7. Rotate limiting rod 16 so that limiting rod 16 connects to the front left side of movable block 15, thereby connecting limiting rod 16 to the front left side of connecting plate 8, which facilitates limiting movable cylinder 14, thus facilitating the winding of connecting line 7.

[0035] When using this non-destructive testing device for steel structure welds that can assist in wire reeling, specific examples include... Figure 1 and Figure 3In this process, the protective plate 3 is installed on the outside of the non-destructive testing instrument 1. The sponge pad 2 is connected to the protective plate 3 by a snap-fit ​​method, and the cross-sectional shape of the sponge pad 2 is a "U" shape, so that the protective plate 3 is snap-fitted on the outside of the non-destructive testing instrument 1, thereby making the non-destructive testing instrument 1 and the sponge pad 2 fit together. The limiting block 9 and the fixing rod 10 are connected by a thread, and the fixing rod 10 is symmetrically distributed about the center line of the protective plate 3. The limiting block 9 is then slidably installed on the front middle side of the protective plate 3. The fixing rod 10 is rotated so that the fixing rod 10 is threaded on the front outer side of the protective plate 3, thereby making the fixing rod 10 threaded on the middle outer side of the limiting block 9, which facilitates the installation of the protective plate 3, so that the sponge pad 2 installed inside the protective plate 3 protects the non-destructive testing instrument 1.

[0036] Specific examples Figure 1 , Figure 3 and Figure 4 In the process, the cylinder 13 is activated. The moving plate 6 and the cleaning cotton 12 are connected by a snap-fit ​​mechanism, and the moving plate 6 and the mounting plate 5 are connected by a sliding mechanism. The cylinder 13 drives the moving plate 6 to slide inside the mounting plate 5, thereby causing the moving plate 6 to drive the cleaning cotton 12 to slide inside the mounting plate 5. This allows the cleaning cotton 12 to wipe the dust off the surface of the display screen 4, facilitating the cleaning of the display screen 4. The moving plate 6 is connected to the mounting rod 11 by a thread and also limits the movement of the cleaning cotton 12. By rotating the mounting rod 11, the mounting rod 11 is threaded to the front middle of the moving plate 6, causing the mounting rod 11 to slide forward at the front of the moving plate 6. This causes the mounting rod 11 to separate from the middle of the cleaning cotton 12, and the cleaning cotton 12 to separate from the rear middle of the moving plate 6, facilitating the replacement of the cleaning cotton 12.

[0037] Specific examples Figure 1 , Figure 5 , Figure 6 and Figure 7In the process, rotating the limiting rod 16 connects the movable block 15 and the connecting plate 8 by rotation. The vertical cross-section of the movable block 15 is a "T" shape, allowing the limiting rod 16 to be threaded on the front left side of the movable block 15. This allows the limiting rod 16 to slide to the left on the front side of the movable block 15, thus separating the limiting rod 16 from the left side of the connecting plate 8. Rotating the movable block 15 allows it to rotate on the left side inside the connecting plate 8. The movable cylinder 14 is connected to the connecting plate 8 by rotation, and the right end of the movable cylinder 14 has a hole-like structure. This allows the movable block 15 to drive the movable cylinder 14 to rotate inside the connecting plate 8, thus allowing the connecting plate 8 to wind the connecting line 7. Rotating the limiting rod 16 allows it to be threaded on the front left side of the movable block 15, thus connecting the limiting rod 16 to the front left side of the connecting plate 8. This facilitates the limiting of the movable cylinder 14, making it easier to reel in the connecting line 7.
