Description
The utility model is a kind of and the supporting twisting machine of wire line coring probing, is used for geological drilling.
Because the rope drilling is slided non-incision drilling rod and joint with unit, old-fashioned utilization up and down fork to carry out the twisting machine of unloading inapplicable, since boring popularization, rope still do not had the use supporting of a kind of comparatively ideal twisting machine so far with it, the unloading drilling rod also prolongs the heavy method of operation by hand always in the drilling well, consuming a large amount of muscle power of workman, affect the reduction of drilling efficiency and cost, the performance that makes rope bore superiority is under some influence.Several ropes that occur at present bore the twisting machine preproduction and then have the chucking power deficiency, use dip angle of hole little on the spot, inadequately safety, bulky, Heavy Weight, it is poor to seal, and the angle of wedge that tangent line constituted of the tangent line of roller and out star wheel circular arc and roller and rope brill drilling rod is unreasonable in the unloading mechanism, excessive or too small, can produce and skid, can not wedging, or wedge is dead easily, can not throw off joint or drilling rod, problem such as moment of torsion is little.
Task of the present utility model is: provide that a kind of chucking power is big, the unloading device can not skid or wedge is dead, moment of torsion is big, safe in utilization, volume is little, rope in light weight, good seal bores the hydraulic pressure twisting machine.
Task of the present utility model is finished in the following manner:
1. be provided with annular piston clamping oil cylinder, utilize the descending pulling force of annular piston, spur three slips and prolong the inclined-plane and move down, draw the firm grip drilling rod simultaneously to the center in.
2. be provided with Di speed Da Niu Ju Pendulum line oil motor, through gear reduction increase turn round after, pass to Moving plate, dialling changes the unloading device and turns round and unload; Be provided with the boosting oil cylinder simultaneously, promote the ratchet Moving plate to increase moment of torsion by ratchet.
3. the unloading device has adopted positive and negative double rolling key clutch mechanism, and preferred structural parameters---the angle of wedge makes unloading device and drilling rod be easy to locking and throws off.
4. be provided with special-purpose inclined hole support, can bore high inclination-angle (75 degree) inclined hole,, can adjust arbitrarily at 90 degree～75 degree angular ranges by adjusting screw rod.
Characteristics of the present utility model: the one, enough chucking powers are arranged, be provided with annular piston clamping oil cylinder mechanism, but clamping weighs 10 tons drilling tool, the 2nd, in the unloading mechanism, the unloading angle of wedge is moderate, does not produce to skid or the dead phenomenon of wedge.Powerful torsional moment is arranged: adopted low-speed big cycloid oil motor, and be provided with the boosting oil cylinder and can make torsional moment up to 400 kilograms/meter.The 3rd, safe and reliable: the operator position is located at the safety zone, causes in order to prevent misoperation in addition and runs the event of running affairs, and has set up the control stick retainer.The 4th, sturdy and durable sealing is tight: housing and base plate adopt the casting of ductile iron one, have not only increased intensity but also alleviated weight; Each major diameter all is provided with " O " RunddichtringO, and each cylinder ports has all been installed the dust protection rubber circle, prevents that the dirt slurry from entering, and reduced component wear.The 5th, this machine is supporting with the rope brill, rope is bored can bore high inclination-angle (75 degree) inclined hole.The 6th, a tractor serves several purposes: not only can the unloading rope bore the non-incision drilling tool of all size (φ 44～φ 75), the otch drilling tool arranged but also unloading is old-fashioned; Also can make the wooden horse clamper separately uses.
