Description

A welding inspection device for steel components Technical Field

[0001] This utility model relates to the technical field of welding inspection devices, specifically a welding inspection device for steel components. Background Technology

[0002] Steel components refer to composite steel structural members capable of bearing and transmitting loads, constructed from steel plates, angle steel, channel steel, I-beams, welded steel, or hot-rolled H-beams that have been cold-bent or welded and connected by connectors. The manufacture of steel structure workshops requires a wide variety of steel components. During production, these components need to be welded together to meet the requirements of the steel structure workshop. The weldability of the steel components must be inspected during production to verify the strength of the welds and whether the weld seams meet the requirements.

[0003] However, existing steel component welding inspection devices have certain shortcomings in actual use. They are used to inspect welding quality and welding strength as needed. Welding quality inspection is mostly carried out by flaw detection. However, welding spatter and slag are present during steel component welding. If these are not cleaned, the accuracy of the inspection will be affected. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel component welding inspection device, including an inspection table, on which movable plates are symmetrically arranged via movable components, and each of the two movable plates is provided with a rotating clamping component. A flaw detector body is provided on the inspection table via a lifting component, and a vertical plate is provided on one side of the middle part of the inspection table. The vertical plate is provided with a grinding mechanism via an adjustment component.

[0008] Preferably, to ensure the clamping effect, the anti-slip pad is provided with anti-slip protrusions at equal intervals.

[0009] Preferably, in order to facilitate the up-and-down movement and adjustment of the flaw detector body for convenient testing, the lifting assembly includes hydraulic telescopic rods equidistantly arranged on the testing platform, and a lifting plate is provided at the output end of the hydraulic telescopic rods, which is connected to the flaw detector body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4. One embodiment of this utility model provides a steel component welding inspection device, including a testing platform 1 for inspecting welded steel components. Hydraulic telescopic rods 4 with lifting components are equidistantly installed on the testing platform 1. A lifting plate 5 is installed at the output end of the hydraulic telescopic rods 4. A flaw detector body 6 (which can be an ultrasonic flaw detector or other mature technologies such as radiographic testing, will not be elaborated here) is installed on the lifting plate 5. The detection part of the flaw detector body 6 is located below the center of the lifting plate 5, facilitating the inspection of the welded steel components. This device is used to detect internal defects in the weld, such as cracks and lack of fusion. The testing platform 1 can also be equipped with other inspection devices for steel component welding, such as welding strength and corrosion resistance testing, depending on actual needs. This is a relatively mature technology. The technical details are not elaborated here. To facilitate the clamping and rotation of steel components and simplify inspection operations, the testing table 1 is provided with equidistant sliding grooves 8 for movable components. A slider 13 slides within the grooves 8, and the slider 13 is connected to the inner wall of the grooves 8 by an electric push rod 12, allowing the slider 13 to slide back and forth within the grooves 8. A movable plate 2 is attached to the top of the slider 13 by screws or welding. A motor 3 for rotating clamping components is installed in the middle of the movable plate 2. A rotating plate 9 is fixedly installed at the output end of the motor 3 via a coupling. Anti-slip pads 10 are adhered to the side walls of the two rotating plates 9 that are close to each other. To better clamp the steel components, anti-slip protrusions 11 are also equidistantly adhered to (or integrally formed with) the anti-slip pads 10, ensuring the clamping effect on the steel components and facilitating subsequent rotation inspection.

[0022] Please refer to Figures 1-4. In order to clean up welding spatter, slag and other impurities at the welding point and avoid affecting the flaw detection, thus ensuring the accuracy of the detection, a vertical plate 7 is welded to one side of the middle of the detection table 1. Electric push rods 14 with adjustment components are symmetrically welded to the side wall of the vertical plate 7. A push plate 15 is fixedly installed at the output end of the electric push rod 14. A sliding rod 20 of the grinding mechanism is symmetrically slidably installed on the push plate 15. A limit plate 18 is welded to one end of the sliding rod 20 to prevent the sliding rod 20 from slipping off. A mounting block 16 is welded to the other end of the sliding rod 20. A spring 19 is sleeved on the outside of the sliding rod 20 between the push plate 15 and the mounting block 16. A grinding block 17 is provided on the side wall of the mounting block 16 (which can be installed by screws or snap-fit, and is a detachable assembly for easy replacement). In order to facilitate the collection of grinding impurities, a collection device can be installed on the detection table 1, which can be composed of a collection box, a collection pipe and a collection cover, etc. This is a relatively mature technology and will not be described in detail here.

[0023] Working principle: In use, the welded steel component to be inspected is placed in the middle of the inspection table 1. The electric push rod 12 retracts, causing the slider 13 to slide within the groove 8. The two moving plates 2 move closer to each other, and the rotating plate 9, in conjunction with the anti-slip pad 10 and anti-slip protrusion 11, clamps and fixes the steel component. Then, the electric push rod 14 extends, moving the push plate 15, which in turn contacts the grinding block 17 on the mounting block 16 with the weld on the steel component. Continuing to move, it generates a compressive force on the mounting block 16, causing the slider 20 to slide and the spring 19 to contract and store. Potential energy is used to extend and retract the hydraulic telescopic rod 4, which moves and adjusts the flaw detector body 6 on the lifting plate 5. This allows for easy adjustment of the distance between the flaw detector and the steel component, facilitating subsequent inspection. At this time, the motor 3 operates, which rotates the rotating plate 9, thereby rotating the steel component. In conjunction with the grinding block 17, the welded area can be ground to remove burrs, weld slag, etc., without affecting subsequent inspection operations. The presence of the spring 19 and the slide bar 20 ensures that the grinding block 17 is always in contact with the welded area of ​​the steel component, ensuring the grinding effect. After grinding, the flaw detector body 6 can operate to inspect the welded area.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
