Description

Technical Field

[0001] The utility model relates to the technical field of steel structure node detection equipment, in particular to a multi-directional detection device used for flaw detection of steel structure nodes. Background Art

[0002] Steel structure is a building structure system that uses steel as the main component. Steel structure has the advantages of light weight, high strength, fast construction speed and good durability. Therefore, it is widely used in the construction field. Steel structure can be used in various types of buildings, including factories, commercial buildings, stadiums, bridges, etc.

[0003] In steel structures, steel structure nodes refer to the parts that connect steel structure components, which are used to transfer loads and ensure the stability of the entire structure. The quality of steel structure nodes will directly affect the safety and performance of the steel structure. Before the steel structure is put into use, in order to ensure the safety and performance of the steel structure, detection devices will be used to detect and inspect the steel structure nodes to find possible defects, cracks or other problems. At present, when detecting and inspecting steel structure nodes, detectors will be used to approach the steel structure nodes and detect the status of the steel structure nodes through ultrasonic and other methods;

[0005] The above patent document discloses a steel structure node welding strength detection device to solve the problem that the detection device is inconvenient to contact steel structures of different sizes and specifications; although the detection device of the above patent can be applied to the detection of steel structure nodes of various sizes and specifications, it is found in the actual detection process of steel structure nodes that the shape, type and angle of the steel structure nodes make it difficult to fully detect the status of the steel structure nodes through detection in a single direction, which is prone to missed detection or incomplete detection, and is not conducive to ensuring the safety of the steel structure nodes.

[0037] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0038] In order to enable the detection device to detect steel structure nodes more comprehensively, this embodiment provides the following design:

The oppositely arranged detection mechanisms 5 facilitate contact detection with the steel structure node from multiple directions.

[0042] The working principle and use process of this utility model:

[0043] When using:

[0044] First, the detection device is fixed on the auxiliary detection device, such as a mechanical arm, and then the steel structure node to be detected is sent to the bottom of the detection device through a conveyor belt. At this time, the steel structure node is located at a position suitable for detection by the adjustment mechanism 3 and the detection mechanism 5;

[0045] Then the motor 2 42 in the driving mechanism 4 drives the driving wheel 43 to rotate, so that the adjusting arm 32 in the adjusting mechanism 3 can slide inside the fixed arm 31, and then the detection mechanism 5 can move with the adjusting plate to continuously adjust the detection position, and the motor 1 23 in the movable mechanism 2 drives the movable disk 22 to rotate, so that the detection mechanism 5 rotates horizontally, further improving the detection range of the detection mechanism 5, thereby facilitating the detection mechanism 5 to perform comprehensive multi-directional detection of the steel structure node;

[0046] During use:

[0047] When the detection mechanism 5 is detecting, the electric push rod 2 51 in the detection mechanism 5 can adjust the distance between the camera 53 and the ultrasonic detector 54 and the steel structure node, so that the detection mechanism 5 can adapt to the shape of the steel structure node;

[0048] Next, the camera 53 acquires image information of the node surface and uploads the appearance of the steel structure node to the computer so that the computer can use image processing technology to analyze the shape, cracks, deformation, etc. of the steel structure node. At the same time, the ultrasonic detector 54 sends ultrasonic waves to the steel structure node and records the reflected signals to detect internal defects and cracks.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
