The specific embodiment
Below in conjunction with accompanying drawing 1-3, the utility model is described in further detail.
Self-centering unscrewing device of the present utility model has a housing 1, and on housing 1, restraining position ring block inner ring 11 is arranged on clamper; Sliding sash 2 is arranged on housing 1 inside, and there is wearing plate 3 sliding sash 2 both sides, and wearing plate 3 contacts with housing 1, and in the course of work, housing 1 slides relatively, after wearing plate wearing and tearing, can change.There are clamping oil cylinder 3 and a pair of slips 6 in sliding sash 2 inside, and 6 one of slips are fixed on clamping oil cylinder 3 piston rods; Another piece is fixed on sliding sash, and clamping oil cylinder 3 piston rods stretch out and promote slips 6 move toward one another, clamp drilling rod.Shackle oil cylinder 8 connects with bearing pin with bearing 9, and the piston rod of shackle oil cylinder 8 connects with bearing pin 7 with housing 1.
Two limited blocks are welded on housing 1, and hexagon socket cap head screw and hex nut are installed on limited block, adjust screw extension elongation and control locating dimension, and limited block is retracted at clamping oil cylinder 3, when between a pair of slips 6, distance is maximum, work.
Bearing fixed head 10 is welded on borer frame by designing requirement position dimension; Bearing 9 is screwed on bearing fixed head 10.
In use, clamping oil cylinder 3 leads to pressure oil to above-mentioned self-centering unscrewing device, and piston rod stretches out, and the slips 6 promoting on piston rod stretches out, and after contact drilling rod, clamping oil cylinder 3 cylinder barrels promote another slips 6 move toward one another of sliding sash 2 drives and clamp drilling rods; The logical pressure oil of shackle oil cylinder 8, piston rod stretches out and promotes housing 1 and drive sliding sash 2 to take drilling rod center line to rotate counterclockwise as axis of rotation, shackle, piston rod extend out to extreme position to be stopped; The logical pressure oil of clamping oil cylinder 3, piston rod is return, and drives slips 6 to be retracted into limited block 5 and limits position, and clamping oil cylinder 3 cylinder barrels promote sliding sash 2 and drive another slips 6 counter motions, unclamp drilling rod; The logical pressure oil of shackle oil cylinder 8, piston rod is retracted and is driven housing 1 and sliding sash 2 to clockwise rotate with the definite axis of rotation of spacing ring inner ring 11, unscrewing device backhaul.
The innovation of the utility model self-centering unscrewing device is: on the basis that shackle process is analysed in depth, determine the clamped position of sliding sash by clamped drilling rod, i.e. self-centering clamps; The position of sliding sash while unclamping by limited block 5 is definite; With respect to reducing by a clamping oil cylinder in existing unscrewing device structure, in principle, only control two crucial states of first and last, pilot process does not need to control, and does not need to use flow divider-combiner.Size is little, and shackle angle is large, and efficiency is high.
The utility model self-centering unscrewing device can use electricity-liquid control technology to realize Long-distance Control, automatically dismantle drill rod thread, clamping stroke is long, can pass through multistage drilling rod, can be applied to the shackle of outer flush drill stem, meet the basic demand of wire line coring drilling process to unscrewing device, be conducive to the automation of wire line coring drilling process.
