In order to address the above problem, the utility model by the following technical solutions:
A kind of rotary drilling rig Li Wei mechanism, comprise mast, the bottom of described mast is hinged with respectively connector and mast oil cylinder, between mast oil cylinder and connector, by movable supporting, is flexibly connected, and the line of centres between connector, mast, mast oil cylinder, movable supporting forms a quadric chain.
Below the further optimization of the utility model to such scheme:
Wherein one end and the mast oil cylinder of described movable supporting are hinged, and movable supporting is rotationally connected by the second bearing pin and connector by paracentral position, and the other end of movable supporting is flexibly connected with connector by support cylinder.
Further optimize: described connector comprises two blocks of side plates that are arranged side by side and are connected to one.
Further optimize: the quantity of movable supporting is two, is arranged side by side between two blocks of side plates of connector.
Further optimize: support cylinder is arranged between two movable supporting, wherein one end of described support cylinder by the first bearing pin and connector be rotationally connected, the other end is rotationally connected with two movable supporting respectively by the 3rd rotating shaft.
Another kind of optimization:
The quantity of movable supporting and support cylinder is respectively two, is separately positioned on the outside of two blocks of side plates of connector.
Further optimize: wherein one end and the mast oil cylinder of every movable supporting are hinged, and the other end is connected with wherein one end of support cylinder by the 3rd rotating shaft.
Further optimize: the other end of described two support cylinders turns two blocks of side plates by the first bearing pin and connector respectively and is dynamically connected respectively.
When the vertical mast of rotary drilling rig, support cylinder drives movable supporting to make mast oil cylinder in maximum arm of force position, and when the vertical mast of mast finishes to become vertical state, support cylinder drives movable supporting to make mast oil cylinder in operating position.
The utility model adopts such scheme, at rotary drilling rig before level erects mast, by the motion of movable supporting, adjust the lower sustainer position of mast oil cylinder, increase the arm of force of mast oil cylinder, reach and lower mast oil cylinder, mast, connector is stressed and improves the effect that mast founds mast mechanism reliability.Mechanism structure of the present invention is compact, has broken through bulk restriction, at rotary drilling rig, stands under the constant prerequisite of mast function, has greatly reduced the stressed of mast Li Wei mechanism, has improved greatly the reliability of mast Li Wei mechanism.Improved the overall performance of rotary drilling rig.
