Description

Quick assembly drill bit for offshore oil drilling Technical Field The utility model relates to a quick assembly drill bit for offshore oil drilling, and belongs to the technical field of drill bits. Background The drill bit is a tool for drilling holes in various materials, is commonly used in industries such as construction, manufacturing, oil and gas exploitation and the like, and is used for breaking rock and forming a borehole when being used for offshore oil drilling, so that the drilling speed and efficiency are improved. Chinese laid-open patent (publication No. CN 220621766U) discloses a high-speed PDC drill bit for offshore oil drilling, including PDC drill bit body and replacement blade, there are blade bodies on the surface of PDC drill bit body through bolted connection, the quantity of blade body is four to twelve, the surface of replacement blade is provided with fixed establishment, the fixed surface of PDC drill bit body is connected with the slide rail fixed establishment includes the counter bore, the counter bore is seted up on the surface of replacement blade, the inner chamber of counter bore runs through and is provided with the bolt body, the quantity of counter bore is a plurality of, the both sides of replacement blade are all fixedly connected with slider, the bottom fixedly connected with stopper of slide rail. According to the utility model, through the cooperation of the replacement blade, the counter bore and the bolt body, the advantage of convenience in replacing different blades is realized, and the replacement of the blade is more convenient, so that the drilling process is more efficient, and the exploitation of offshore oil is facilitated; however, the damage to part of the blades may be more serious due to the different wear degrees of the contact surfaces of the drill bit, but the existing drill bit generally cannot replace the damaged part of the blades, and the whole replacement of the blades can make the cost higher, and the efficiency of oil drilling is reduced. For this purpose, a rapid assembly drill bit for offshore oil drilling is proposed. Disclosure of utility model In view of the foregoing, the present utility model provides a quick-install drill bit for offshore oil drilling that solves or alleviates the technical problems of the prior art, and at least provides a beneficial choice. The technical scheme is that the quick assembly drill bit for offshore oil drilling comprises a connector, wherein the top of the connector is movably connected with a mounting column, the inner side of the connector is provided with a sliding groove, the bottom of the mounting column is movably connected with the inner side of the connector, the outer side of the connector is provided with a bolt, and the inner side of the bolt penetrates through the connector and extends to the inner side of the mounting column.
