[0001] The present application relates to the technical field of non-destructive testing equipment for steel structures, in particular to a non-destructive testing instrument for steel structure detection. BACKGROUND

[0002] Steel structural members are common support components in life. Buildings using steel structures only need to quickly connect the steel structures and the pre-embedded parts embedded in the ground through bolt connection to build the frame of the entire building, which can greatly shorten the construction time of the building, and the steel structural members can ensure sufficient strength to ensure the stability of the building. Therefore, steel structural members are widely used in production plants, agricultural greenhouses, breeding plants and other buildings.

[0003] The steel structure flaw detector disclosed in the Chinese utility model patent with the authorization announcement number CN216117471U needs the staff to hold the probe close to the surface of the steel structural member to be detected for detection during work, and the probe is connected with the flaw detector body through wires, which makes it necessary for the staff to hold the probe and walk through all parts of the steel structural member to be detected to complete the detection work when detecting the steel structural member located at a high place, greatly increasing the labor intensity of the staff.

The present invention, through the configuration of a first hydraulic cylinder in conjunction with two sets of rotating components, can simultaneously drive two sets of biting rollers and two sets of anti-falling components to approach each other until they clamp the steel structure to be inspected. This coordination allows the inspection instrument to move automatically along the steel structure to be inspected when the rotating components drive the biting rollers and anti-falling components to rotate, thus eliminating the need for the operator to hold the inspection equipment continuously during the inspection process, effectively reducing the labor intensity of the operator.

[0020] 2. The present invention, through its adjustable grip component, allows the testing instrument to be delivered to higher and farther locations without the aid of climbing or moving tools, further reducing the labor intensity of the staff. In cases where it is not suitable for the testing instrument to move on its own, the flaw detection unit can be detached from the support, and then the adjustable grip component can be used to drive the flaw detection unit to perform flaw detection on the steel structural components within the reachable range. This increases the flexibility of the flaw detector and further improves its practicality.

[0021] 3. The present invention can change the angle between the bracket and the handle by setting the steering component, so that during the flaw detection work, the angle can be flexibly adjusted according to the positional relationship between the part to be detected and the worker. In this way, while ensuring the accuracy of the detected structure, the worker can be in the most labor-saving working state, further reducing the labor intensity of the worker.

[0048] When it cannot walk by itself, the staff holds the grip 8031 and sends the flaw detection unit 200 to the steel structure to be detected, and then starts the second drive motor 8025 to drive the rotating plate 8026 and the grip 8031 to rotate to adjust the angle between the flaw detection unit 200 and the grip 8031, so that the flaw detection unit 200 is parallel and adheres to the surface of the steel structure to be detected, and then the staff holds the flaw detection unit 200 to detect the parts of the steel structure to be detected.
