Abstract
The invention relates to a chucking device, in particular to a quick-change slips hydraulic rubber cylinder chuck which adapts to a full hydraulic power head drill machine. When the slips of the prior hydraulic rubber cylinder chuck is replaced, a hydraulic slips disc needs to be integrally disassembled for reassembly, and under most conditions, the rubber cylinder is replaced simultaneously, so the service life of the rubber cylinder is manually shortened, and the production cost is increased. On the basis of the hydraulic rubber cylinder chuck, the quick-change slips hydraulic rubber cylinder chuck is additionally provided with the slips, a slips seat and an end press cover, and when the slips in different specification sizes is replaced, only the end press cover needs to be disassembled so as to pump out the slips from the slips seat. The hydraulic chuck does not need to be integrally disassembled so as to achieve the aim of quick change. The quick-change slips hydraulic rubber cylinder chuck has small outline dimension and low opening pressure, is beneficial to the pressure coordination between branch paths of a hydraulic system, improves the efficiency of the hydraulic system and also has the advantages of safe and reliable chucking work of the hydraulic rubber cylinder chuck and small rotation inertia. When the quick-change slips hydraulic rubber cylinder chuck is matched with a hydraulic holder in the hydraulic system with the function of linkage, the quick-change slips hydraulic rubber cylinder chuck can guarantee the coordinated motion.
Description
Technical field
The present invention relates to a kind of gripping mechanism, is the quick-change slips hydraulic rubber cylinder chuck that adapts on the all-hydraulic power head rig specifically, links to each other with the unit head output shaft of rig usually, is used to tighten kelly, and makes the transmission of torque of unit head give drilling tool in the hole.
Background technology
Hydraulic pressure packing element chuck in the past all needs oild chuck integral body is taken apart when changing slips, re-assemblies; As a rule, also all change packing element simultaneously, in the application life that this has just shortened packing element artificially, increased cost of production.
Chuck is as one of main executing agency of all-hydraulic drill, and when the basic demand of its proposition was the chucking drilling rod, action was wanted rapidly, and enough clamping forces are arranged, and guarantee not produce relative slip between captured drilling rod and the slips.Specifically, it is simple that structure is wanted, and clamping force is big, and dynamic moment of inertia is little; When rig has the interlock function, require the opening and closing movement of chuck and clamper to coordinate, to guarantee all the time that promptly one of them clamps drilling rod after, another mechanism unclamps again.In addition, opening force is low when unclamping, so that reduce the size of spring.When changing the slips of different specification size, make things convenient for easily the packing element long service life.
Summary of the invention
The invention provides a kind of when changing the slips of different specification size, quick, simple, practical quick-change slips hydraulic rubber cylinder chuck.
For achieving the above object, its technical scheme is:
Quick-change slips hydraulic rubber cylinder chuck comprises passing and draws dish, bonnet, chuck body, packing element, Supporting ring, slips, end pressure ring, torque-transmission disk, protecgulum, spring and backing plate; Described biography draws dish, bonnet, chuck body, packing element, Supporting ring, end pressure ring, protecgulum and backing plate to form monolateral pliable pressure cavity volume; Its special character is: the ring-shaped inner part at monolateral pliable pressure cavity volume is provided with slip spider, forms the biography clamping force element that is made of slip spider, slips, spring, and the axial end of described slip spider is positioned on the protecgulum aperture edge; The axial arranged outside torque-transmission disk of slips in the described slip spider, the axial arranged outside end gland of torque-transmission disk; For the male and female draw-in groove is slidingly connected, be connected for latch that can transmitting torque between torque-transmission disk and bonnet and the protecgulum between described slips and the torque-transmission disk.
For the male and female draw-in groove is connected, bowl and slips inwardly slides under the constraint of torque-transmission disk (12) draw-in groove between above-mentioned slips and the slip spider.
Above-mentioned slips is connected with torque-transmission disk male and female draw-in groove, and the axial fit clearance of the flexibility that improves the slips slip is set between the two.
Slips in the above-mentioned slip spider is the slips of different specification size.
The present invention is with respect to prior art, and its advantage is as follows:
The present invention has set up slips and slip spider and end gland on the basis of hydraulic pressure packing element chuck.At the slips of changing different specification size, only need lay down the end gland, slips can be extracted out in slip spider, need not the whole decomposition of oild chuck is realized the purpose of quick change; It has hydraulic pressure packing element chuck and clamps the safe and reliable and little advantage of dynamic moment of inertia;
Appearance and size of the present invention is little, and opening pressure is low, and the pressure that helps between each branch road of hydraulic system is coordinated, and has also improved the efficient of hydraulic system; In the hydraulic system that the interlock function is arranged, cooperate, but safety action is coordinated with hydraulic gripper.
