Abstract

The invention discloses a vibration test device,and relates to the field of anti-vibration detection. The vibration test device comprises a rack,a driven mechanism and a driving mechanism; the drivenmechanism comprises a vibration table and a vibration gear; the driving mechanism comprises a spur rack,a vertical bar,a push air cylinder and a slide bar,the slide bar and the push air cylinder are connected with the rack,the vertical bar is connected with the slide bar in a slide block form,a piston of the push air cylinder is connected with the vertical bar,and multiple layers of vibration reduction rings are arranged on the lower surface of the spur rack and located at the top end of the vertical bar; the vibration table is placed on the upper side of the rack,and the lower surface of thevibration table is provided with the vibration gear matched with the spur rack. The vibration test device has the advantages of being high in vibration efficiency,adjustable in vibration intensity andlong in service life.

Description

technical field [0001] The invention relates to the field of anti-seismic detection, in particular to an anti-seismic detection device for small instruments. Background technique [0002] As a big country in infrastructure construction, our country has infrastructure projects blooming all over the country. The three giants of infrastructure "roads, bridges, and tunnels" are marching into remote areas, deep mountains and old forests. The first step of all infrastructure projects is on-site measurement, so the environment for the use of precision measuring instruments is more complicated. Before reaching the measuring point, the measuring instrument will inevitably go through various vibrations and collisions to reach the measuring point. Therefore, the seismic testing of precision instruments is a must. However, the volume of existing anti-seismic testing instruments is too large, and the structure is too complex, which is not suitable for small precision instruments such a...
