Description

Technical Field

[0001] This utility model relates to the field of non-destructive testing equipment for steel structures, and in particular to a non-destructive testing equipment for steel structures with a lifting function. Background Technology

[0002] Non-destructive testing (NDT) equipment for steel structures refers to a class of devices capable of performing non-destructive testing on steel structures. These devices can detect defects both internally and on the surface of the steel structure, such as cracks, porosity, and inclusions, while simultaneously determining its internal composition, structure, physical properties, and condition, without impairing or affecting its future performance or application. Common NDT equipment for steel structures includes X-ray flaw detectors, ultrasonic flaw detectors, and magnetic particle flaw detectors. These devices play a crucial role in industrial production and quality control, and are widely used in construction, bridges, shipbuilding, and other fields to ensure the safety and reliability of steel structures.

[0003] In current technologies, most non-destructive testing (NDT) equipment for steel structures is operated by hand by the inspector. The inspector holds the equipment in one hand and the probe in the other, bringing the probe into contact with the steel structure being inspected. However, this method requires holding the equipment and probe for extended periods, making it cumbersome. Furthermore, the difficulty in adjusting the equipment's height makes it unsuitable for inspecting steel structures at different heights or locations. This can lead to the probe not being able to fully contact the steel structure surface, affecting the accuracy of the inspection. Additionally, the inspector frequently needs to bend over or stand on tiptoe to adjust the equipment's height, increasing both operational difficulty and inspection efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a non-destructive testing device for steel structures with lifting function, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A steel structure non-destructive testing device with lifting function includes a non-destructive testing instrument, a probe, and a base. The non-destructive testing instrument and the probe are connected by a connecting line. The top surface of the base is provided with an adjustment mechanism, which includes a support cylinder, a first drive motor, a screw, a lifting cylinder, a top plate, a second drive motor, a drive gear, an L-shaped plate, a driven gear, and an electric push rod. The support cylinder is fixedly connected to the top surface of the base, and the first drive motor is fixedly connected to the bottom surface of the fixed plate inside the support cylinder. The screw is fixedly connected to the output end of the first drive motor, and the lifting cylinder is movably connected to the screw through an adjusting nut at its inner bottom. The top plate is fixedly connected to the top of the lifting cylinder, and the second drive motor is fixedly connected to the bottom surface of the top plate. The drive gear is fixedly connected to the output end of the second drive motor. The L-shaped plate is movably connected to the bottom surface of the top plate through a rotating rod on the top surface of its horizontal part, and the driven gear is fixedly connected to the top of the rotating rod and meshes with the drive gear. The non-destructive testing instrument is fixedly connected to the front wall of the vertical part of the L-shaped plate through a fastening nut.

[0007] Furthermore, universal wheels are fixedly installed at the four corners of the bottom surface of the base, and a support cylinder is fixedly installed on the top surface of the base. A fixing plate is fixedly installed inside the lower part of the support cylinder, and a set of symmetrical sliding grooves are opened on the inner wall of the support cylinder.

[0008] Furthermore, the first drive motor is fixedly installed on the bottom surface of the fixed plate, and a screw is fixedly installed at the top of the output end of the first drive motor. The lifting cylinder is inserted and installed inside the support cylinder, and a set of symmetrical sliders are fixedly installed on the bottom of the outer wall of the lifting cylinder and movably installed in the slide groove. An adjusting nut is fixedly installed at the bottom of the inner side of the lifting cylinder, and the adjusting nut is threadedly connected to the screw.

[0009] Furthermore, the top plate is fixedly installed on the top surface of the lifting cylinder, and a second drive motor is fixedly installed on the bottom surface of the top plate. A drive gear is fixedly installed at the top of the output end of the second drive motor. A rotating hole is also opened in front of the top surface of the top plate, and a rotating rod is fixedly installed on the top surface of the horizontal part of the L-shaped plate and movably installed in the rotating hole. The driven gear is fixedly installed at the top of the rotating rod, and the driven gear and the drive gear mesh together.

[0010] Furthermore, a set of symmetrical mounting holes are provided on the front wall of the vertical part of the L-shaped plate.

[0011] Furthermore, an electric actuator is fixedly installed on the top of the rear wall of the vertical part of the L-shaped plate, and a probe is fixedly installed at the front end of the output end of the electric actuator. A set of symmetrical threaded short rods is fixedly installed on the rear wall of the non-destructive testing instrument, and the threaded short rods are inserted into the mounting holes. The fastening nut is threadedly connected to the threaded short rods.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the adjustment mechanism allows the entire device to be moved via casters on the base, eliminating the need to hold the non-destructive testing instrument for extended periods during steel structure inspection. Activating the first drive motor rotates the screw, causing the lifting cylinder to move upwards along the screw via the adjusting nut and exit the support cylinder. This allows adjustment of the operating height of the non-destructive testing instrument and probe. Activating the second drive motor then rotates the driving gear, which in turn rotates the driven gear. The driven gear, through a rotating rod, rotates the L-shaped plate, enabling the L-shaped plate to move the non-destructive testing instrument mounted on the front wall. The instrument rotates to adjust the probe's orientation. Once the probe's height and orientation align with the inspection area of ​​the steel structure, the electric actuator is activated to drive the output end, pushing the probe firmly against the steel structure surface for inspection. This allows the non-destructive testing instrument to have height and orientation adjustment functions, adapting to the inspection needs of steel structures at different heights or locations. It also ensures the accuracy of steel structure inspection and is simple and convenient to operate, eliminating the need for personnel to hold the equipment. This simplifies the operation of the non-destructive testing instrument for steel structure inspection and improves inspection efficiency. Attached Figure Description

[0020] like Figure 1 - Figure 4 As shown, a steel structure non-destructive testing device with lifting function includes a non-destructive testing instrument 1, a probe 3, and a base 4. The non-destructive testing instrument 1 and the probe 3 are connected by a connecting line 2. The top surface of the base 4 is provided with an adjustment mechanism 6, which includes a support cylinder 7, a first drive motor 10, a screw 11, a lifting cylinder 12, a top plate 15, a second drive motor 16, a drive gear 17, an L-shaped plate 19, a driven gear 21, and an electric push rod 24. The support cylinder 7 is fixedly connected to the top surface of the base 4, and the first drive motor 10 is fixedly connected to the bottom surface of the fixing plate 8 inside the support cylinder 7. The screw 11 is fixedly connected to the first... The output end of the drive motor 10 is connected to the lifting cylinder 12 via the adjusting nut 14 at the bottom of the inner end and the screw 11. The top plate 15 is fixedly connected to the top of the lifting cylinder 12, and the second drive motor 16 is fixedly connected to the bottom surface of the top plate 15. The drive gear 17 is fixedly connected to the output end of the second drive motor 16. The L-shaped plate 19 is movably connected to the bottom surface of the top of the horizontal part via the rotating rod 20. The driven gear 21 is fixedly connected to the top of the rotating rod 20 and meshes with the drive gear 17. The non-destructive testing instrument 1 is fixedly connected to the front wall of the vertical part of the L-shaped plate 19 via the fastening nut 22.

[0021] like Figure 2 As shown, universal wheels 5 are fixedly installed at the four corners of the bottom surface of the base 4. The entire equipment can be moved by the universal wheels 5 on the bottom surface of the base 4. A support cylinder 7 is fixedly installed on the top surface of the base 4. A fixing plate 8 is fixedly installed inside the lower part of the support cylinder 7. The fixing plate 8 can be used to install and fix the first drive motor 10. A set of symmetrical sliding grooves 9 are opened on the inner wall of the support cylinder 7. The sliding grooves 9 are used to cooperate with the slider 13 to limit and guide the movement of the lifting cylinder 12.

[0022] like Figure 2As shown, the first drive motor 10 is fixedly installed on the bottom surface of the fixed plate 8, and a screw 11 is fixedly installed at the top of the output end of the first drive motor 10. The lifting cylinder 12 is inserted into the support cylinder 7, and a set of symmetrical sliders 13 are fixedly installed on the bottom of the outer wall of the lifting cylinder 12 and movably installed in the slide groove 9. An adjusting nut 14 is fixedly installed at the bottom of the inner side of the lifting cylinder 12, and the adjusting nut 14 is threadedly connected to the screw 11. When the first drive motor 10 is turned on, the output end drives the screw 11 to rotate, which allows the adjusting nut 14 to move upward along the screw 11, and drives the lifting cylinder 12 to move from the inside to the outside of the support cylinder 7 through the sliders 13 on both sides along the slide groove 9, so as to achieve the purpose of adjusting the height of the non-destructive testing instrument 1 and the probe 3, so that the non-destructive testing instrument 1 has a lifting function.

[0023] like Figure 3 As shown, the top plate 15 is fixedly installed on the top surface of the lifting cylinder 12, and the bottom surface of the top plate 15 is fixedly installed with the second drive motor 16. The top of the output end of the second drive motor 16 is fixedly installed with the drive gear 17. A rotating hole 18 is also opened in front of the top surface of the top plate 15. A rotating rod 20 is fixedly installed on the top surface of the horizontal part of the L-shaped plate 19 and is movably installed in the rotating hole 18. The driven gear 21 is fixedly installed on the top of the rotating rod 20, and the driven gear 21 and the drive gear 17 are meshed together. When the second drive motor 16 is turned on, the drive output end drives the drive gear 17 to rotate. The drive gear 17 will drive the driven gear 21 to rotate under the rotation meshing action. The driven gear 21 will drive the rotating rod 20 to rotate in the rotating hole 18. The rotating rod 20 will drive the L-shaped plate 19 to rotate, so that the L-shaped plate 19 drives the non-destructive testing instrument 1 to rotate, so as to achieve the purpose of adjusting the orientation of the non-destructive testing instrument 1 and the probe 3, so that the non-destructive testing instrument 1 has the function of adjusting according to the position of the steel structure.

[0024] like Figure 3 As shown, a set of symmetrical mounting holes 23 are provided on the front wall of the vertical part of the L-shaped plate 19. The mounting holes 23 are used to cooperate with the installation of the non-destructive testing instrument 1.

[0025] like Figure 3 and Figure 4As shown, an electric actuator 24 is fixedly installed on the top of the rear wall of the vertical part of the L-shaped plate 19, and a probe 3 is fixedly installed at the front end of the output end of the electric actuator 24. A set of symmetrical threaded short rods 25 are fixedly installed on the rear wall of the non-destructive testing instrument 1, and the threaded short rods 25 are inserted into the mounting holes 23. The fastening nut 22 is threadedly connected to the threaded short rods 25. By passing the threaded short rods 25 through the mounting holes 23 and connecting the fastening nut 22 to the threaded short rods 25, the non-destructive testing instrument 1 can be fixed on the front wall of the vertical part of the L-shaped plate 19. By turning on the electric actuator 24, the output end is driven to push the probe 3 to the surface of the steel structure, which can be used to inspect the steel structure. This eliminates the need for the inspector to hold the probe 3 for a long time and ensures the accuracy of the steel structure inspection.

[0026] The specific operating principle of the adjustment mechanism 6 in conjunction with the non-destructive testing instrument 1 is as follows:

[0027] After inserting the threaded short rod 25, which is mounted on the rear wall of the non-destructive testing instrument 1, into the mounting hole 23 on the front wall of the vertical part of the L-shaped plate 19, and then threading the fastening nut 22 onto the threaded short rod 25, the non-destructive testing instrument 1 can be installed and fixed on the front wall of the vertical part of the L-shaped plate 19. The entire device can be moved by holding the support cylinder 7 and using the casters 5 on the bottom surface of the base 4. When the device is moved to the steel structure inspection area, the height of the non-destructive testing instrument 1 and the probe 3 can be adjusted according to the height of the steel structure. During adjustment, the first [unclear] mounted on the bottom surface of the fixed plate 8 is activated. The first drive motor 10 drives the screw 11 to rotate, causing the lifting cylinder 12 to move upward along the screw 11 via the adjusting nut 14 at the bottom of its interior. During this movement, the sliders 13 on both sides of the bottom of the outer wall of the lifting cylinder 12 slide in the grooves 9 on both sides of the inner wall of the support cylinder 7, causing the lifting cylinder 12 to move upward and outward from the inside of the support cylinder 7 until the probe 3 is adjusted to the height position of the steel structure detection. Then, the second drive motor 16, installed on the bottom surface of the top plate 15, is turned on. The second drive motor 16 drives the drive gear 1 to rotate. 7. Rotation: The driving gear 17 will drive the driven gear 21 to rotate under the meshing action. The driven gear 21 will drive the rotating rod 20 to rotate within the rotating hole 18 on the top surface of the top plate 15. The rotating rod 20 will drive the L-shaped plate 19 to rotate. The L-shaped plate 19 will drive the non-destructive testing instrument 1 mounted on the front wall to rotate until the probe 3 rotates and is aligned with the position to be tested on the steel structure. Then, the electric push rod 24 mounted on the rear wall of the vertical part of the L-shaped plate 19 will be activated. The electric push rod 24 will drive the output end to push the probe 3 mounted at the front end until the probe 3 is in close contact with the surface of the steel structure to be tested. The steel structure is inspected using probe 3, and the obtained signals are transmitted to the non-destructive testing instrument 1 via connecting cable 2 to complete the inspection operation. This allows the non-destructive testing instrument 1 to have height and orientation adjustment functions to meet the inspection needs of steel structures at different heights or positions, while ensuring the accuracy of the inspection. The operation is simple and convenient, eliminating the need for inspectors to hold the equipment, thus bringing convenience to inspectors when using the non-destructive testing instrument 1 to inspect steel structures and improving inspection efficiency.
