Rock core compaction equipment in laboratory

The utility model provides rock core compaction equipment in a laboratory, mainly solving the problem that a current laboratory is lack of effective rock core compaction equipment. The equipment is characterized by comprising a positioning plate, a supporting plate, a rock core mould clamping frame and a rock core filling mould, wherein a first positioning body and a second positioning body are distributed at the left and right ends of the supporting plate; the positioning bodies are provided with through slide grooves along a horizontal direction; the supporting plate is located above a jackscrew; the rock core mould clamping frame is composed of two single bodies with a symmetrical structure; each single body is composed of a U-shaped block with a clamping groove, a vertical-direction clamping plate and a bottom clamping plate which are connected to form a whole body; the width of each clamping groove is the same as the diameter of steel-made supporting rods; the width of each U-shaped block is the same as that of each slide groove; the upper end of each vertical-direction clamping plate is provided with at least two hydraulic plunger piston positioning plates and an upper flange disc clamping plate at intervals from top to bottom. The equipment can be matched with hydraulic machinery and does not need to be held by hands of an experimenter; the rock core compaction equipment has the characteristics of high rock core compaction efficiency and good quality.
