Abstract

The invention discloses a hydro-electric-hybrid-driven rotary drilling rig. An electro-hydraulic mechanical cylinder or a hydraulic mechanical cylinder is adopted to replace a traditional piston cylinder, and driving is conducted in a hydro-electric-hybrid-driven mode. An existing mechanical structure of the rotary drilling rig does not need to be changed, only a hydraulic cylinder in the rotary drilling rig needs to be replaced with the electro-hydraulic mechanical cylinder or the hydraulic mechanical cylinder in the hydro-electric-hybrid-driven rotary drilling rig, thus the control precisionof the rotary drilling rig can be improved, and gravitational potential energy of working parts is recycled to achieve energy saving.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a hydraulic-electric hybrid driven rotary drilling rig. Background technique [0002] Rotary drilling rig is a kind of construction machine for hole forming in construction engineering, and it is widely used in various foundation constructions such as cast-in-place piles, diaphragm walls, and foundation reinforcement. Rotary drilling rigs mainly include drilling tools, drill pipes, power heads, pressurized cylinders, luffing mechanisms, masts, main winches, auxiliary winches, car bodies, and walking mechanisms. The lifting and lowering of the mast, the change of the angle of the mast during work, and the stability of the support are realized by the expansion and contraction of the luffing hydraulic cylinder, so as to realize the adjustment of the position and verticality of the drilling tool. The power head controls the rotation of the drilling tool through the power head mot...
