Drilling platform for amphibious operations

A drilling platform for amphibious operations, comprising:

• a base (1) and an operating platform (13) fixed on the base (1) for drilling, wherein drive tracks (12) are arranged on both sides of the base (1), a propeller is disposed at a rear end of the base (1), and a driving assembly is disposed inside the base (1) to respectively cooperate with the drive tracks (12) and the propeller;
• two support cylinders (4) are respectively disposed at two ends of the base (1), and bottom ends of the support cylinders (4) penetrate the base (1) to be flush with a bottom surface of the base (1);
• each of the support cylinders (4) contains a sub-cylinder (2) coaxial therewith;
• a bottom end of the sub-cylinder (2) is sealed, and a partition plate (201) for isolating the sub-cylinder (2) into two separate regions is mounted on an internal circumferential wall of the sub-cylinder (2);
• a pushing cylinder (202) is arranged on a bottom surface of the partition plate (201);
• a circular sealing organ cover (203) is arranged on the internal circumferential wall of the sub-cylinder (2), and a small-diameter open end of the sealing organ cover (203) is connected to a middle of an output end of the pushing cylinder (202);
• a follower plate (204) is mounted at an end portion of the output end of the pushing cylinder (202);
• a plurality of sliding slots (208) are provided on an external circumferential wall at a bottom end along a circumferential direction of the sub-cylinder (2), and a plurality of grooves (207) are formed on the internal circumferential wall of the bottom end along the circumferential direction of the sub-cylinder (2);
• longitudinal sections of the grooves (207) are right-angled triangles, and bottoms of the grooves (207) communicate with the sliding slots (208);
• a plurality of linkage rods (205) are fixed on a bottom surface of the follower plate (204), and a bottom of each of the linkage rods (205) is respectively hinged with an anchor claw (206);
• a bottom end of the anchor claw (206) extends downwardly along oblique sides of the grooves (207) into the sliding slots (208);
• when the output end of the pushing cylinder (202) extends to a maximum stroke, bottom ends of the linkage rods (205) are completely moved out of the sliding slots (208);
• while external sidewalls of the linkage rods (205) contact with the oblique sides of the grooves (207), the internal sidewalls of the linkage rods (205) contact with the internal walls of the sliding slots (208);
• a buoyancy adjustment assembly is provided at a bottom of the base (1), so as to provide buoyancy support for the base (1) when the base (1) is transferred from land to water.
