Abstract

The invention relates to the field of rotary drilling rigs, in particular to a lifting device of a mast of a rotary drilling rig and the rotary drilling rig. The lifting device comprises an upper support, a lower support and a plurality of oil cylinders. A plurality of first hinge points are arranged at one end of the upper support. A plurality of second hinge points are arranged at the other endof the upper support. A plurality of third hinge points are arranged at one end of the lower support. A plurality of fourth hinge points are arranged at the other end of the lower support. At least two of the oil cylinders are hinged to the first hinge points and the third hinge points. At least two of the oil cylinders are hinged to the second hinge points and the fourth hinge points. The upper support and the lower support are connected with a mast of the rotary drilling rig. In the scheme, the plurality of hinge points are arranged on the supports, the two sides of the supports are each provided with at least two oil cylinders, a mast mechanism can rise or fall after the plurality of oil cylinders jointly act on a fulcrum of the mast, the pull-up force of the oil cylinders of the largerotary drilling rig on the mast is satisfied, the working pressure of a hydraulic pump is reduced, the service life is prolonged, and the structural strength of the mast and a uranium bar part of therotary drilling rig is enhanced.

Description

technical field [0001] The invention relates to the technical field of rotary drilling rigs, in particular to a lifting device for a mast of the rotary drilling rig and the rotary drilling rig. Background technique [0002] At present, the mast of the rotary drilling rig is the supporting part of the drilling tool, the adjustment mechanism and the pressurization system, etc., and the entire mast plays a vital role in the normal operation and working quality of the rotary drilling rig. The mast needs to be kept in a vertical state when it is working normally, and it is put away to ensure a horizontal state when it is not working. Therefore, the rotary drilling rig needs to take off and land the mast. The mast is generally vertical or horizontal through the lifting device. [0003] With the demand for large-scale rotary drilling rigs, in order to ensure the safety and practicality of the rotary drilling rig, the height and weight of the mast need to be greatly increased, which...
