Description

Technical Field

[0001] This utility model belongs to the field of steel structure inspection technology, specifically relating to a support arm for an inspection vehicle used for steel wall crawling inspection. Background Technology

[0002] Steel structure engineering is a structure mainly made of steel. In order to ensure the structural strength of steel structure buildings, ultrasonic flaw detectors are needed to inspect the welds of these steel structure building materials after the steel structure construction is completed. This is to avoid situations such as false welding or missing welding that affect the construction and safety of steel structure buildings. For steel wall crawlers to be able to crawl safely and reliably continuously and freely on irregular curved surfaces, their magnetic wheels must maintain reliable contact with the steel wall without interruption. However, the existing magnetic wheels have poor floating effect and poor contact effect between each magnetic wheel and the irregular curved surface. When crawling on the irregular curved surface of irregular metal components, the contact between each magnetic wheel and the metal surface is quite different, which will cause uneven distribution of magnetic adsorption force, resulting in unstable operation of the magnetic crawling device, and even falling accidents due to gravity. Summary of the Invention

[0003] To overcome the problems of poor floating effect and poor contact between the magnetic wheels and irregular curved surfaces in existing technologies, which lead to uneven distribution of magnetic adsorption force when crawling on irregularly shaped metal components, resulting in unstable operation of the magnetic crawling device and even falling accidents due to gravity, this utility model provides a support arm for a detection vehicle used for steel wall crawling detection. By installing support arms on both sides of the detection vehicle, when crawling on irregularly shaped metal components, the supporting force on each elastic connecting component 2 and elastic connecting rod 6 changes with the curvature of the surface. The side plate 1 can swing relative to the vehicle frame, and the wheel frame 3 can swing relative to the side plate 1, which can ensure the floating effect of each magnetic wheel, the contact and adsorption effect between each magnetic wheel and the metal surface, the uniform distribution of magnetic adsorption force of each magnetic wheel, the stable operation of the crawling detection device, and avoid the occurrence of falling accidents.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A support arm for a detection vehicle used for steel wall crawling detection mainly includes a side plate 1, an elastic connecting component 2, a wheel frame 3, a lever arm 4, a connecting plate 5, and an elastic connecting rod 6. The back of the side plate 1 is hinged to the frame of the detection vehicle through a hinge lug 11. The two ends of the elastic connecting component 2 are respectively hinged to the side plate 1 and the frame. One side of the wheel frame 3 is hinged to the bottom end of the side plate 1. A magnetic wheel is installed inside the wheel frame 3. The lever arm 4 is installed upright on the wheel frame 3. The connecting plate 5 is installed on the top outer side of the lever arm 4. The two ends of the elastic connecting rod 6 are respectively hinged to the side plate 1 and the connecting plate 5.

[0005] Furthermore, the connecting plate 5 is mounted on the lever arm 4 by adjusting bolt 12. The end of the adjusting bolt 12 is rotatably and axially limited on the lever arm 4. The connecting plate 5 is threadedly connected to the adjusting bolt 12, and the end of the adjusting bolt 12 is provided with a bolt head for easy adjustment.

[0006] Furthermore, the elastic connection assembly 2 includes an elastic spring 21 and a connecting plate 22. The connecting plate 22 is fixedly installed at both ends of the elastic spring 21, and the connecting plates 22 at both ends are respectively hinged to the side plate 1 and the frame.

[0007] Furthermore, the elastic connecting rod 6 includes a sleeve 61, a piston rod 62, and a spring. The spring is installed inside the sleeve 61, and one end of the piston rod 62 is telescopically installed inside the sleeve 61. The ends of the sleeve 61 and the piston rod 62 are respectively hinged to the side plate 1 and the connecting plate 5.

[0008] The beneficial effects of this utility model are: This invention, by installing support arms on both sides of the inspection vehicle, allows the vehicle to crawl on irregularly shaped metal components. As the surface of the vehicle changes, the supporting force on each elastic connecting component and elastic connecting rod changes. The side plates can swing relative to the vehicle frame, and the wheel frame can swing relative to the side plates. This ensures the floating effect of each magnetic wheel, the contact and adsorption effect between each magnetic wheel and the metal surface, the uniform distribution of the magnetic adsorption force of each magnetic wheel, and the stable operation of the crawling inspection device, thus preventing falls.

[0013] This utility model discloses a support arm for a testing vehicle used for steel wall crawling detection. The support arm mainly includes a side plate 1, an elastic connecting assembly 2, a wheel frame 3, a lever arm 4, a connecting plate 5, and an elastic connecting rod 6. The back of the side plate 1 is hinged to the frame of the testing vehicle via hinge lugs 11. The two ends of the elastic connecting assembly 2 are respectively hinged to the side plate 1 and the frame. One side of the wheel frame 3 is hinged to the bottom of the side plate 1. A magnetic wheel is installed inside the wheel frame 3. The lever arm 4 is erected on the wheel frame 3. The connecting plate 5 is installed on the outer top of the lever arm 4. The elastic connecting rod... The two ends of the 6 are respectively hinged to the side plate 1 and the connecting plate 5; by installing support arms on both sides of the inspection vehicle, when crawling on the irregular curved surface of the irregularly shaped metal component, the supporting force on each elastic connecting component 2 and elastic connecting rod 6 changes with the change of the curved surface. The side plate 1 can swing relative to the frame, and the wheel frame 3 can swing relative to the side plate 1, which can ensure the floating effect of each magnetic wheel, ensure the contact and adsorption effect between each magnetic wheel and the metal surface, ensure the uniform distribution of the magnetic adsorption force of each magnetic wheel, ensure the stable operation of the crawling inspection device, and avoid the occurrence of falling accidents.

[0014] In this embodiment, the connecting plate 5 is mounted on the lever arm 4 by adjusting bolt 12. The end of the adjusting bolt 12 is rotatably and axially limited on the lever arm 4. The connecting plate 5 is threadedly connected to the adjusting bolt 12. The end of the adjusting bolt 12 is provided with a bolt head for easy adjustment. The distance between the connecting plate 5 and the side plate 1 can be changed by adjusting bolt 12, thereby changing the compression of the elastic connecting rod 6 and realizing the adjustment of the support force of the elastic connecting rod 6, so as to better adapt to the crawling detection of steel walls with different curved surfaces.

[0015] In this embodiment, the elastic connection component 2 includes an elastic spring 21 and a connecting plate 22. The connecting plate 22 is fixedly installed at both ends of the elastic spring 21, and the connecting plates 22 at both ends are respectively hinged to the side plate 1 and the frame.

The spring is installed inside the sleeve 61, and one end of the piston rod 62 is telescopically installed inside the sleeve 61. The ends of the sleeve 61 and the piston rod 62 are respectively hinged to the side plate 1 and the connecting plate 5.

[0017] Work process: By installing support arms on both sides of the inspection vehicle, when crawling on the irregular curved surface of the irregularly shaped metal component, the supporting force on each elastic connecting component 2 and elastic connecting rod 6 changes with the change of the curved surface. The side plate 1 can swing relative to the frame, and the wheel frame 3 can swing relative to the side plate 1. This ensures the floating effect of each magnetic wheel, the contact and adsorption effect between each magnetic wheel and the metal surface, the uniform distribution of the magnetic adsorption force of each magnetic wheel, and the stable operation of the crawling inspection device, thus avoiding the occurrence of falling accidents.
