Summary: | The utility model discloses an oil cylinder self-recycling device for an oil cylinder lifting drilling machine. The oil cylinder self-recycling device comprises a lug plate A, a lug plate D, a lug plate C, a lug plate E and a lug plate B, wherein the lug plate A, the lug plate D and the lug plate C are welded to the preset installation positions of the same side face of a derrick, and the lug plate E and the lug plate B are welded to a base. The lug plate D is hinged to the end of a piston rod of a multistage oil cylinder, the end of the multistage oil cylinder is connected with the lug plate E through a pin shaft in an inserting mode, and a pulley is installed on an outer barrel of the head end of the multistage oil cylinder. One end of a guiding steel wire rope is led out of the lug plate A through a shackle, and the other end of the guiding steel wire rope is connected with the lug plate B sequentially through a rope clamp thimble and a basket bolt after penetrating through the pulley. The oil cylinder self-recycling device is independent of the matching of a crane, operators operate the basket bolt and a hydraulic system at a low position, low-position operation is achieved, the multistage oil cylinder is automatically fixed at a high position, safety and reliability are achieved, cost is reduced, and the installation quality and the safety of the operators are ensured. |
