1. An integrated detection test device for a drill bit and a rotary blowout preventer, comprising: a support frame, wherein a rotary shaft is mounted on the support frame, and an upper end of the rotary shaft is connected to a first hydraulic cylinder fixed on the support frame; the rotary shaft is connected to a driving device through a rotary disc sleeved outside the rotary shaft;
a pit sinking to a fixing plane of the support frame is arranged below the support frame; an L-shaped track and a transport vehicle slidably connected to the track are mounted in the pit, the transport vehicle is connected to a piston rod of a third hydraulic cylinder when reaching a preset position, and the first hydraulic cylinder and the third hydraulic cylinder are both connected to a hydraulic station;
a fixed base for fixing a drill bit test bench is mounted at a tail end of the track positioned right below the support frame; the drill bit test bench comprises a specimen platform, a specimen groove for placing a specimen is formed in the specimen platform, and a through hole penetrating through the specimen platform is formed in a bottom of the specimen groove; a platform support base is fixed at a bottom of the specimen platform and is connected to the fixed base in a detection state; a cavity for accommodating a clamping device is arranged inside the platform support base; a pressing device for pressing the specimen is movably connected to the specimen platform;
when the drill bit test bench is lifted by the first hydraulic cylinder to control the clamping device to move upwards, a lower end of the rotary shaft is capable of being connected to the clamping device through a rotary shaft joint;
when the drill bit is detected, the lower end of the rotary shaft is capable of being connected to the drill bit with a screw;
when the rotary blowout preventer is detected, the lower end of the rotary shaft is capable of being connected to a test drill pipe with a screw;
the clamping device comprises a rod, a claw and a driving mechanism for folding and unfolding the claw relative to the rod, and the rotary shaft is connected to the rod through the rotary shaft joint; and
a control console and a pressure test pump are mounted on one side of the hydraulic station; and the hydraulic station, the driving device and the pressure test pump are all electrically connected to the control console.
