Abstract

The invention discloses a rock breaking device for a petroleum drilling rock stratum. The device comprises a bearing frame and mounting strips, wherein limiting grooves are formed in the upper surfaceof the bearing frame, sliding grooves are formed in the edges of the inner walls of the limiting grooves, sliding blocks are mounted in the sliding grooves, hydraulic cylinders are mounted at the topend of the bearing frame, rock breaking drill bits are mounted below driving motors, connecting heads are welded to the top ends of the rock breaking drill bits, the mounting strips are mounted on the left side and the right side of the outer wall of the bearing frame, the inner walls of the mounting strips are provided with protective plates and fixing plates, the right side of the protective plates are provided with the fixing plates, the edges of the inner walls of the fixing plates are provided with fixing grooves, the tail ends of the protective plates are welded with hoop plates, and the inner walls of the protective plates are provided with backflow mechanisms. According to the rock breaking device, the rock breaking drill bits are convenient to be replaced for a user, so that theusing work efficiency of the drill bits is excellent, and the surrounding workers is protected in the rock breaking operation process.

Description

technical field [0001] The invention relates to the technical field related to oil drilling rock formations, in particular to rock breaking equipment for oil drilling rock formations. Background technique [0002] The discovery of oil storage blocks after exploration refers to the use of special equipment and technology to drill cylindrical holes with a certain diameter downward or on one side at a pre-selected surface position, and to drill underground oil and gas layers. In the process of drilling rock formations and breaking rocks, oil drilling rock formation rock breaking equipment is needed. [0003] However, the currently used oil drilling rock formation rock-breaking equipment is not convenient for users to replace the rock-breaking drill bit, which makes the use of the drill bit inefficient, and does not have the ability to protect the surrounding staff during the rock-breaking process. [0004] For this reason, propose a kind of rock breaking equipment of oil well ...
