The utility model relates to a novel mobile hydraulic well drilling and rock grabbing apparatus used in the construction process of well establishment of mines, which comprises a hydraulic hoist, wherein the hydraulic hoist comprises a brace rod, a hoisting rod and a supporting rod, wherein the brace rod is bound to a positioning plate by a U-shaped guard staple, and a gear wheel is arranged on the brace rod. A slideway is horizontally arranged on the positioning plate corresponding to the position of the gear wheel on the brace rod, and a rack bar meshing with the gear wheel is arranged in the slideway, wherein the end of the rack bar is provided with a handle. A hydraulic cylinder is hinged with the brace rod, the tail of a supporting rod is connected with a telescopic rod of the hydraulic cylinder and a rod head of the supporting rod is hinged with the rear half part of the hoisting rod. The utility model has the advantage of simple structure and reasonable design. The utility model realizes the purposes that the hoisting rod not only can drive a rock grabbing machine up and down, but also can rotate left and right at a certain fixed point position of annular railway rails. Therefore, the utility model is more convenient for under-well construction of mines, increases the work efficiency further and reduces the labor intensity.
