Abstract

The utility model discloses a trolley displacement mechanism of a stone cutting machine. The trolley displacement mechanism comprises a lower trolley and two transverse tracks, wherein the two transverse tracks are arranged in parallel; the lower trolley is spanned over the transverse tracks through sliding blocks; a dual-output-rod oil cylinder is fixedly arranged between the two transverse tracks through an oil cylinder support seat and is provided with two piston rods; the extending ends of the two piston rods are close to the two ends of the transverse tracks; pulleys are arranged at the ends of the piston rods; a steel rope is wound on each pulley; and the ends of the steel ropes are correspondingly fixed to the oil cylinder support seat and the lower trolley. In the trolley displacement mechanism of the stone cutting machine, even if the transverse displacement of the lower pulley is increased exponentially, the retractable travel of each piston rod is only half of the displacement of the lower trolley, and the structure is very simple; even if each steel rope is fatigue and relax, sliding fit between each steel rope and each pulley cannot be influenced; and the precise placement of a transverse displacement action can be kept by the lower trolley.
