Description
Technical field
The utility model relates to the drilling equipment technical field, is specifically related to a kind of multi-functional clamp of rig.
Background technology
The colliery underground drill rig be coal mining must use equipment, at present, domestic and international existing slip-type colliery underground drill rig slewing equipment is broadly divided into following two classes:
One class is " glue bucket, slip-type ", namely holds tightly in the drilling rod process at slewing equipment, and hydraulic oil is exerted pressure to the radial direction of glue bucket, and the glue bucket that pressurized shrinks is exerted pressure to the slips in the glue bucket, and behind the compression slips spring, slips is held drilling rod tightly.In unclamping the drilling rod process, hydraulic oil refluxes, and pressure is removed, and under the rebound effect of spring, slips is got back to original position, no longer holds drilling rod tightly.The problem that this class rig slewing equipment exists is: 1, slips is easy to generate fatigue and plastic strain, causes slips can not get back to original position fully.Cause drilling rod to pass through smoothly; 2, spring is fractureed, and the spring that fractures is pricked the glue bucket bad, causes the leakage of oil of glue bucket, must change spring and glue bucket, thereby can't use; Pad when 3, rig is worked between slips and the slips is shifted easily, and its wedge angle is pricked the glue bucket and leaked, and causing changing the glue bucket could use; When 4, using the drilling rod of different-diameter, drill pipe diameter must need to change respective slips less than rig line shaft diameter of bore, wastes time and energy.
Another kind of is the equally distributed block slips that is provided with radial penetration through hole axle at drill power head through hole axle, and this structure is because it must consider the intensity of through hole axle, so, the physical dimension of slips, that can not design is excessive, between the adjacent slips very big gap must be arranged.Slips can in the cylindrical drilling rod fashion of clamping, when card prismatic drilling rod, just can't guarantee that slips can block the corner angle of drilling rod, in such cases, gently then block tight drilling rod, heavy then damage slips and drilling rod, even because the friction of trackslipping produces bigger spark, stayed the major hidden danger that is difficult to estimate to safety in production, and reduced efficiency greatly.Other existing problems are described identical with the first kind.
In addition, rig generally adopts common chuck clamping round bur bar as kelly when the prismatic drilling rod that uses greater than rig line shaft endoporus, connects special-shaped drilling rod and the mode that moment of torsion and the slide force of rig passes to special-shaped drilling rod is crept into kelly.During dismounting drilling rod, adopt the mode of manpower manual teardown, waste time and energy, frock efficient reduces, and workman's operational danger is very big.
