Abstract
The invention discloses a hydraulic control follow-up type chain pressurization device; and the device mainly consists of a hydraulic revolving device assembly, a driving chain wheel assembly, a cross coupling, a driven chain wheel, two double-row chains, two guide chain wheels and a pressurization chassis. When a lifting mechanism of a drilling machine drives a power head to ascend or descend, as the pressurization device adopts a floating oil way, the chains move along with the power head; when the pressurization device performs a pressurization action, a main windlass brake is turned on, and the lifting mechanism can move along with the pressurization action again; the two mechanisms are coordinated in actions without being interfered; and although the two mechanisms are different in loads, the two mechanisms cannot influence mutual operations.
