1results about How to "High structural utilization" patented technology

This invention relates to the field of static pressure testing technology, and provides a structural strength testing device for road and bridge construction, including a frame, a line fixing structure, a pressure testing module, a tensile testing module, and a rotary adjustment module. The line fixing structure includes a teardrop-shaped cable protrusion, a shaft connector, a pressure bearing platform, a hook pin, a displacement sensor, and a mother frame. The shaft connector is fixedly disposed between the teardrop-shaped cable protrusion and the mother frame. The pressure bearing platform and the displacement sensor are both fixedly disposed on the surface of the mother frame. The hook pin is fixedly disposed on the surface of the teardrop-shaped cable protrusion. The tensile testing module includes a pull ring and a pressure-applying protrusion, with the pressure-applying protrusion fixedly disposed inside the pull ring. The rotary adjustment module includes a pressure-bearing protrusion, which can contact the surface of the pressure-bearing protrusion. A spring is disposed between the mother frame and the frame. This invention solves the problems of single function, low efficiency, and high cost of existing technologies, and has the characteristics of high integration, high structural utilization, small size, and complete functions.
