The technical scheme that its technical problem that solves the utility model adopts is: comprise framework, hydraulic cylinder, slips and slips guide holder; Described frame roof is provided with suspension hook; Described hydraulic cylinder is loaded in the framework regularly, and the piston rod of hydraulic cylinder is connected with gripper shoe, is provided with swivel plate on gripper shoe, and the upper end and the swivel plate of slips are hinged, and makes slips can realize axial rotation; The domatic that the described slips outside is big up and small down, the slips guide holder is placed on outside the slips, and establishing the sliding shoe that matches with chute on the slips guide holder on the lateral surface of slips, slips can be slided up and down along the slips guide holder; The upper end holding of above-mentioned slips guide holder is in supporting seat, and this slips guide holder can carry out the capable rotation of axle; Corresponding framework place is provided with bearing in the outside, slips guide holder lower end.During work, when carrying out the slinging during operation of bar, hydraulic cylinder at first is in contraction state, slips is opened, after drilling rod upper end entered in the framework from the bottom of framework, hydraulic cylinder stretched and drives slips and hold the drill pipe coupling head tightly, again the winch lift frame of establishing by other, drilling rod makes the chute of slips outside slide block and slips guide holder press from both sides tighter and tighter in the effect of self gravitation, thereby has guaranteed stability and the safety of drilling rod in lifting process.And two drilling rods are linked to each other when being connected into double joint when needs, drilling rod rotates under the effect of the hydraulic tongs that other joins, and drives slips and the slips guide holder rotates in the lump, and framework and hydraulic cylinder do not rotate.
Further, for realizing the length travel compensation of drilling rod in lifting process, be provided with two leads at the top of framework, compensating plate, compression spring and stop nut from bottom to top are housed on two leads successively, described suspension hook is loaded on the compensating plate.
Further, be to guarantee the utility model and the even running of drilling rod in lifting process, be provided with pulley bracket and the pulley that matches with derrick in a side of framework, thereby make framework in lifting process, realize steady lifting along derrick by guide rail and pulley.
Further, after entering the framework inner chamber, bump, above slips, be provided with the drilling rod fairlead with other parts for preventing drilling rod.
Further, enter framework smoothly, on the framework below the slips, be provided with flaring drilling rod introducing port for making drilling rod.
The beneficial effects of the utility model are: rational in infrastructure, easy to operate, reduced labor strength effectively, and improved operating efficiency and security reliability.
