The invention discloses a lifting and moving device for a blowout preventer (BOP) of a slant-hole drilling rig. The lifting and moving device comprises a device body, a winch, a steel wire rope for the winch, fixed pulleys, lifting steel wire ropes, lifting cylinders, a sliding cylinder and movable pulleys. One end of the sliding cylinder is connected with a drilling rig base, and the other end of the sliding cylinder is connected with the device body. Pulley sliding rail assemblies are further arranged on the front side face and the rear side face of the device body, the pulleys or sliding rails are fixed to the side faces of the device body, and the sliding rails or the pulleys are fixed to the drilling rig base. One end of each lifting cylinder is fixed to the device body, and the other end of each lifting cylinder is connected with the corresponding movable pulley. The fixed pulleys are fixed to the device body. One end of each lifting steel wire rope is fixed to the device body through a fixing base, and the other end of each lifting steel wire rope sequentially winds across the corresponding movable pulley and the corresponding fixed pulleys. A lifting hook is arranged at the tail end of each lifting steel wire rope. The winch is fixed to the device body, and the steel wire rope for the winch is arranged on the winch. According to the lifting and moving device, horizontal moving of the BOP can be achieved by controlling the sliding cylinder; lifting and adjustment of the inclination angle of the BOP are achieved by controlling the lifting cylinders and the winch, and the device is simple, light and convenient to operate.
