摘要:
For splitting rock, concrete structures, etc., by being inserted into a drill hole created therein, a rock splitter has a wedge coupled at its thick end to the output shaft of a hydraulic cylinder. Lying on opposite sides of the wedge, a pair of guides are yieldably held against the wedge to allow longitudinal sliding motion thereof. Two pairs of opposed leaf springs connect the wedge guides to the hydraulic cylinder to restrain the guides from longitudinal displacement and to allow same to move away from and toward each other with the longitudinal sliding motion of the wedge. The pair of wedge guides, together with the wedge therebetween, generally taper as they extend away from the hydraulic cylinder for the ease of insertion into the drill hole. Several splitting operations, each with a thrust of the wedge, are to be performed in succession, by inserting the splitter progressively deeper into the drill hole, for fracturing thick rock formations or the like.
