Drilling-tower-free drilling method with adjustable drilling inclination

A drilling-tower-free drilling method with adjustable drilling inclination is based on a rock core drilling machine, and the rock core drilling machine comprises a drilling machine body, a power device, a winch, a gearbox, a vertical shaft shell and a vertical shaft. The drilling method comprises the following steps: 1, early-stage installation work; 2, installation of a guide wheel A and a guidewheel B; 3, starting of drilling; 4, pulling out of a drill; 5, adding of a new drill rod; 6, drilling; 7, completing of the connection of the new drill rod; and 8, restarting of drilling. The two guide wheels are used for changing the pulling force (pulling out) direction or the pushing force (drilling down) direction of a steel wire rope; and the drilling method overcomes the defect that a traditional rock core drilling machine cannot drill down and pull out smoothly when the drilling inclination is too large, achieves efficient drilling at any angle ranging from 0 degree to 90 degrees (namely the rock core drilling
