Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel member detection, in particular to a steel member load bearing test and anticorrosion layer adhesion detection platform. BACKGROUND

[0002] In the field of traditional steel member detection, the load bearing test and anticorrosion layer adhesion detection of steel members are mostly completed by two independent devices, which need to be transported and positioned multiple times, resulting in complicated operation, long time consumption, and accumulated errors caused by repeated positioning. Moreover, the load bearing test device can only provide static load and cannot simulate static and dynamic combined stress in actual working conditions, making it difficult to meet the detection requirements in complex scenarios. The anticorrosion layer adhesion detection relies on manual grid drawing, adhesive tape pasting, and visual rating, which is greatly affected by operation method and subjective judgment, resulting in large errors and insufficient objectivity of the detection results.

[0003] In addition, the clamping device of the traditional device cannot be compatible with steel members of different specifications, which may cause the member to deviate during testing due to vibration. The detection platform lacks precise horizontal adjustment function, and the inclination of the platform will directly affect the verticality of load application and the accuracy of deformation monitoring. At the same time, the load control of the load bearing test is mostly in open loop mode, which cannot provide real-time feedback and adjustment, making it difficult to adapt to the efficient quality screening requirements of large-scale steel members and restricting the improvement of detection efficiency and data reliability.

[0022] Working principle: as shown, Figures 1-10 Positioning and clamping: place the steel member to be detected in the positioning and clamping assembly 2 area of the workbench 1. The rotary motor one 21 drives the screw rod one 22 to rotate, which drives the two pairs of clamps 23 to move towards each other along the guide rail 24 until the clamps 23 tightly fit the two sides of the steel member, achieving horizontal fixation.
