Multi-functional drilling experiment platform

A multi-functional drilling experiment platform, comprising:

• a gantry,
• a hydraulic cylinder,
• a power swivel, and
• a platform base,
• wherein
• the gantry comprises a gantry rib, a gantry column, a column support lug, a crossbeam, a pulling-pressing hydraulic cylinder lug, a pulling-pressing force sensor, a gantry double lug, a limiting platform, a guide pillar mounting seat, a guide pillar, a guide pillar rib, a crossbeam guide seat, and a crossbeam support lug;
• the gantry rib is fixed on two gantry columns by bolts,
• the column support lug is fixed on the gantry column by welding,
• the guide pillar mounting seat, the guide pillar, and the guide pillar rib are installed in a U-shaped steel channel of the gantry column;
• the crossbeam guide seat is fixed with both ends of the crossbeam by screws,
• the crossbeam guide seat is configured to move upwards and downwards through the cooperation of the crossbeam guide seat and the guide pillar;
• the hydraulic cylinder of the multi-functional drilling experiment platform is divided into a pitching hydraulic cylinder and a pulling-pressing hydraulic cylinder,
• the pitching hydraulic cylinder is composed of a pitching hydraulic cylinder plunger and a pitching hydraulic cylinder block
• the pulling-pressing hydraulic cylinder is composed of a pulling-pressing hydraulic cylinder block and a pulling-pressing hydraulic cylinder plunger;
• the pitching hydraulic cylinder plunger is connected to the column support lug by a first pin,
• the length of the pitching hydraulic cylinder is changed by a hydraulic control system to realize a rotation of the gantry;
• the pulling-pressing hydraulic cylinder block is fixed on both ends of the crossbeam through a trunnion seat,
• the pulling-pressing hydraulic cylinder plunger is installed on the pulling-pressing hydraulic cylinder lug by a second pin,
• the length of the pulling-pressing hydraulic cylinder is changed by the hydraulic control system to move the crossbeam along the guide pillar;
• the power swivel is in a middle of the crossbeam,
• the power swivel is composed of a hydraulic motor and a reduction gear;
• the platform base comprises a gantry support lug, a platform pedestal, a drill rod clamping device, and a track slider;
• the gantry support lug is installed to the platform pedestal by bolts,
• the drill rod clamping device is installed under a wellbore of the platform pedestal to clamp the experimental drill rod;
• the track slider is provided on both sides of the platform pedestal to cooperate with a ground track to realize a movement of the multi-functional drilling experiment platform;
• a gantry double lug is connected to the gantry support lug through a pin shaft,
• an angle of the gantry with respect to a ground is changed under an action of the pitching hydraulic cylinder to achieve multi-angle drilling experimental simulation, and
• since the experimental simulation is mostly vertical drilling experiment simulation, a rotary pin shaft is used to strengthen the gantry double lug and the gantry support lug to increase a reliability of the experiment platform.
