Secondary drilling cramp, described rotary shaft is located between main drilling cramp and secondary drilling cramp, and the distance between main drilling cramp and central shaft are equal to secondary brill
The distance between frame and central shaft;Be respectively arranged with the guide rail of two vertical directions on main drilling cramp and secondary drilling cramp, and guide rail with
It is mutually parallel between main drilling cramp, secondary drilling cramp, active force head is provided with the guide rail on main drilling cramp, the guide rail on secondary drilling cramp
It is upper that secondary unit head is set, main landing gear is rotatably connected to main drilling cramp junction in substrate, turn with secondary drilling cramp junction in substrate
It is dynamic to be connected with auxiliary landing gear, a winch, No. two winches are provided with substrate;Hawser on a number winch bypasses master and rises and falls
Main drilling cramp top is extended to after frame, and is bypassed and is connected with active force head after the pulley on main drilling cramp top, the steel wire on No. two winches
Rope is bypassed and extend to after auxiliary landing gear secondary drilling cramp top, and is bypassed and be connected with secondary unit head after the pulley on secondary drilling cramp top, in base
Main brace bar and secondary hound are provided with plate, main brace bar be connected with the upper position of main drilling cramp, secondary hound and pair drilling cramp
Upper position connection;Into 0-90 ° of angle between main brace bar and main drilling cramp, into 0-90 ° between secondary hound and secondary drilling cramp
Angle;Support bar is outward extended with respectively at the two ends of substrate, and at the two ends of each support bar downward propping up is respectively arranged with
Support seat.
Above-mentioned technical proposal, in use, according to drilling needs, then weight balancing centre mount positioning utilizes
Secondary unit head on secondary drilling cramp drives the drilling rod that fetches earth to be fetched earth, after the completion of fetching earth, then dynamic inside weight balancing centre mount
Force mechanisms drive 180 ° of rotary shaft and substrate rotating, make the active force head on main drilling cramp be directed at lower section operating area, using actively
Power head drives drilling drilling rod to complete region to fetching earth and drills, and carries out subsequent construction operation after drilling again.In said process, nothing
Complete to fetch earth and bored pile by the position for needing mobile drill, can greatly reduce use cost, while improving construction operation
Efficiency.The design of main landing gear, auxiliary landing gear, can reduce a winch, the pulling force that No. two winches are born, so as to for power
The increase of nose heave amount and provide safeguard, in addition main drilling cramp, secondary drilling cramp are symmetrical arranged, and obtain further the stationarity of rig
Lifted, while only need to rotate that both job state switchings are completed by 180 °, it is simple and convenient.
The top of main drilling rod is provided with main suspension rod, the outboard end of main suspension rod is located at the side of guide rail, sets on substrate
Put No. three winches, the hawser of No. three winches is extended to after the pulley on main drilling cramp top further around the pulley of excessively main suspension rod outboard end
