Abstract

The invention relates to a load testing machine which comprises a luggage carrier and a testing frame. The testing frame is matched with the luggage carrier. A moving component and two moving bracketsare arranged on the luggage carrier, the two moving brackets are separately positioned at two ends of the luggage carrier; the moving component controls the two moving brackets to move in the opposite directions at the same time; a lifting component, a pressure sensor and a pressing shovel are arranged on the testing frame, the pressure sensor is positioned between the lifting component and the pressing shovel, the lifting component is matched with the pressing shovel, the pressing shovel is matched with a sample on each moving bracket. The load testing machine adopting the scheme is mainly used for detecting the mechanical properties of linear load test and uniformly distributed load test of composite products such as a plastic glass steel grating, a glass steel grating cover plate, a glass steel grating plate, a pultrusion glass steel grating, a pultrusion glass steel profile and acrylic artificial marbles, meets production requirements, and prevents substandard composite products from flowing into markets.

Description

technical field [0001] The invention relates to a testing device, especially a load testing machine. Background technique [0002] FRP grating, also known as FRP grating, is a plate-like material with many spaces that uses glass fiber as a reinforcing material and unsaturated polyester resin as a matrix. As a structural material, it is used as a floor, trench cover, platform, ship deck, stairs, plank road, etc. in a corrosive environment. It has the characteristics of corrosion resistance and flame retardant, non-magnetic insulation, bright colors, and various styles and forms for selection. [0003] During its use, the FRP grating is often subjected to the impact of a certain load. After a long time, the FRP grating will suffer from fatigue damage, which will cause it to fail and cannot be used. Therefore, before the FRP grating leaves the factory, test methods are used to quickly and effectively detect the impact of the impact on the FRP grating, so as to judge whether i...
