Description

Technical Field

[0001] This utility model relates to the field of steel structure testing technology, and in particular to a non-destructive testing device for the quality of steel structure engineering. Background Technology

[0002] Steel structures are a type of building structure made of steel materials and are widely used in construction engineering.

[0003] Steel components are integral parts of steel structures. Traditional flatness testing of steel structural components requires manual measurement point by point using a handheld dial indicator, which suffers from problems such as unstable positioning and low testing efficiency, and is particularly unsuitable for irregularly shaped components and simultaneous testing of multiple surfaces. Existing fixed testing stations cannot meet the need for rapid adaptation to different sample sizes. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a non-destructive testing device for the quality of steel structure engineering, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of the present invention provides a non-destructive testing device for the quality of steel structure engineering, including a base and a steel structure positioning seat, wherein the top of the base is detachably connected to the steel structure positioning seat;

[0007] The base has a track fixedly connected to two corners of its top surface, and a slider is movably connected to the track.

[0008] The height and rotation angle of the slider are adjustable. The side of the slider is threaded with a fastening pin, and the end of the fastening pin abuts against the track.

[0009] The slider has a groove on its upper part, and a main shaft is movably connected to the root of the groove. A main board is fixedly connected to one side of the main shaft. The main board is rotatable and its angle is adjustable.

[0010] A dial indicator is mounted on the front end plate of the main board, and a fastener is threaded to the end of the spindle, which is fastened to the side of the slider.

[0011] Preferably, in any of the above solutions, the base is connected to the steel structure positioning seat by a number of screws.

[0012] The above technical solution is adopted: This device is specially used for quality inspection of steel structure components, and the inspection item is the flatness of the surface of the steel component sample.

[0013] The steel structure sample is directly fitted or clamped onto the steel structure positioning seat. The model of the steel structure positioning seat is optional and the steel structure positioning seat is detachable.

[0014] The dial indicator is used to test the flatness of the surface of the steel structure sample. The dial indicator angle is adjustable, and the height of the slider structure supporting the dial indicator is adjustable and can be rotated. The testing structure (track, slider, fastening pin, main shaft, main board, dial indicator, and fasteners) is installed at both corners of the base, allowing for simultaneous testing of different surfaces of the steel structure sample. This results in high testing efficiency. The dial indicator posture is adjustable, enabling flatness testing of the vertical and inclined surfaces of steel component samples of different shapes and irregularities, making it flexible in use.

[0020] The three-dimensional adjustment and detection unit is symmetrically configured: the slider is made of 6061-T6 aluminum alloy casting, with embedded ball bearings to achieve stepless lifting on the track. Precision fastening pins are equipped with polyurethane friction heads, using M8 threads to lock the slider position. The rotating spindle is located in a groove on the upper part of the slider, supporting 0-180° horizontal rotation. The adjustable main plate is connected to the spindle via a flange bearing, with a length of 300mm (50mm beyond the groove). The high-precision dial indicator is equipped with a universal connector, measuring a stroke of ±5mm and a resolution of 0.01mm.
