Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber cloth detection, in particular to a carbon fiber cloth strength detection device. Background Art

[0002] Carbon fiber cloth is used for tensile, shear and seismic reinforcement of structural components. It is usually woven with 12K carbon fiber yarn. This material is used together with the matching impregnated glue to form a carbon fiber composite material, which can form a complete carbon fiber cloth sheet reinforcement system with excellent performance. At present, the existing carbon fiber cloth needs to be tested for strength after production.

[0003] For example, the Chinese patent publication number CN 214096938 U discloses a breaking strength detection device for carbon fiber cloth production, including a base plate, a fixing mechanism, a cross bar and a bearing plate, a column is fixedly provided on one side of the upper surface of the base plate, and a bearing plate is slidably provided on the other side, a rotating plate is rotatably installed on the upper surface of the bearing plate, a hydraulic cylinder is vertically provided on the upper surface of the rotating plate, and the telescopic end of the hydraulic cylinder is fixedly connected to the bottom end surface of the support plate, a clamping sleeve with an internal hollow structure is installed on the upper surface of the support plate, a rotating shaft is rotatably passed through the interior of the clamping sleeve, one end of the rotating shaft facing the column is connected to the output shaft of a driving motor fixedly connected to the support plate, and the other end is connected to the fixing mechanism; the fixing mechanism includes an upper clamping plate and a lower clamping plate, the upper surface of the lower clamping plate is rotatably connected to one end of a threaded rod, and a groove is also opened through the interior of the upper clamping plate.

[0004] This patent sets a rotating plate, a hydraulic cylinder, a driving motor and a clamping sleeve so that the fixing mechanism can rotate in multiple directions, effectively improving the detection range of the carbon fiber cloth. However, the two ends of the carbon fiber cloth are wrapped around the groove and clamped by the upper clamping plate and the lower clamping plate. During the pulling process, due to the small contact area between the groove and the carbon fiber cloth, the local force at the connection between the clamping plate and the carbon fiber cloth is relatively large, which can easily cause tearing at the connection between the carbon fiber cloth and the clamping plate, affecting the detection results.
