Description
Technical field
The utility model relates to a kind of link supports device, is specifically related to a kind of three joint link supports devices that are used for rotary drilling rig.
Background technology
Rotary drilling rig is a kind of soil taking hole forming filling pile construction machinery; In various construction foundation workings, enjoy favor in recent years; The mast of rotary drilling rig is the mounting platform of equipment; Mast is divided into upper, middle and lower three joints usually, and three joint masts become a linear pattern integral body through hinged-support and Bolt Connection thereof during duty, and equipment can slidably reciprocate up and down along the mast guide rail as required.When duty forwards travel position to, passing through to shrink mast oil cylinder; In on the mast, partly fell together until the placement that is up to the standard; But for convenient transportation, following mast still keeps vertical position and links through hinged-support and middle mast, and this process becomes " movable mast "; If need return duty; Through the elongation mast oil cylinder part on the mast is erected together, and then is connected into linear pattern integral body again with following mast, during connection for the mating face is close to; Following mast still must keep vertically, and this process becomes " upright mast ".When " movable mast " or " upright mast ", remain vertical position for making down mast, a bracing or strutting arrangement must be arranged.
Rotary drilling rig in the past has only main winch to be installed in down on the mast usually; Following mast backside space is bigger; Bracing or strutting arrangement can directly use one two power rod member to connect the mast back side and union body bottom down through hinged-support; But this need descend to leave enough spaces on the mast back side, and when the major and minor hoist engine of rotary drilling rig all is installed in down the mast back side, does not obviously possess this condition.
The utility model content
When the utility model technical problem to be solved provides a kind of major and minor hoist engine when rotary drilling rig and all is installed in down the mast back side, can satisfy " movable mast " or " the three joint link supports devices that are used for rotary drilling rig of the requirement of upright mast fully.
In order to solve the problems of the technologies described above; The three joint link supports devices that are used for rotary drilling rig that the utility model provides; Middle mast is hinged through the 3rd bearing pin and union body; Described middle mast 1 is hinged through the 4th bearing pin and following mast; One end of second connecting rod is hinged through an end of first bearing pin and first connecting rod; The other end of described second connecting rod is hinged through an end of second bearing pin and third connecting rod; The other end of described first connecting rod is fixed on the bottom of described union body, and the other end of described third connecting rod is fixed on the bottom of described down mast, and the centre distance of described first bearing pin at the two ends of described second connecting rod to the centre distance of described second bearing pin and described the 3rd bearing pin to described the 4th bearing pin equates and the line of described first bearing pin and described second bearing pin is parallel to the line of described the 3rd bearing pin and described the 4th bearing pin.
Described first connecting rod is fixed on the bottom of described union body through two the 5th bearing pins.
Described third connecting rod is fixed on the described bottom of mast down through two the 6th bearing pins.
Adopt the three joint link supports devices that are used for rotary drilling rig of technique scheme; Because an end of second connecting rod is hinged through an end of first bearing pin and first connecting rod; The other end of second connecting rod is hinged through an end of second bearing pin and third connecting rod, and the other end of first connecting rod is fixed on the bottom of union body, and the other end of third connecting rod is fixed on down the bottom of mast; Because union body itself can be done translational motion with luffing mechanism within the specific limits; Then whole mast and equipment thereof also can be followed union body and moved together, and simultaneously, middle mast can rotate around the 3rd bearing pin on the union body.When " movable mast " or " upright mast ", connect also and can rotate each other through the 4th bearing pin between middle mast and the following mast.Mast remains vertical state in order to make middle mast rotate at present around the 3rd bearing pin, and first bearing pin at the two ends of second connecting rod equates with the centre distance of the 3rd bearing pin to the four bearing pins and the line of first bearing pin and second bearing pin is parallel to the line of the 3rd bearing pin and the 4th bearing pin that to the centre distance of second bearing pin central point of establishing the 3rd bearing pin is A; The central point of the 4th bearing pin is B, and the central point of second bearing pin is C, and the central point of first bearing pin is D; Like this; With A, B, C, four bearing pin centers of D is that the mechanism that hinged point is formed promptly constitutes a dynamic parallel-crank mechanism, and according to the characteristic of parallel-crank mechanism, wherein the AD limit is fixed with respect to union body; The frame that is equivalent to parallel-crank mechanism; When the AB limit with middle mast when the 3rd bearing pin rotates, the CD limit all the time with AB limit keeping parallelism, the BC limit is then along with doing translational motion; The following mast at place, BC limit is as long as be vertical under the initial state like this; Under so no matter middle mast at " movable mast " still was " upright mast " state, following mast all must be vertical, has reached instructions for use fully.When needing operate as normal after " upright mast " accomplished, three joint link supports devices can all or part ofly according to circumstances be pulled down the dismantlement work simple and fast.
In sum; The utility model is a kind of major and minor hoist engine when rotary drilling rig when all being installed in down the mast back side, can satisfy " movable mast " or " requirement of upright mast and the three joint link supports devices that are used for rotary drilling rig simple and reliable for structure, that do not account for mast space, easy accessibility fully.
