Abstract
The utility model relates to a clamping device, in particular to a slips quick-replacing hydraulic rubber cylinder clamping disc which is suitable for being used on a full-hydraulic power head drilling machine. The previous hydraulic rubber cylinder clamping disc needs to be taken apart and assembled again in an entire manner when slips are replaced, and a rubber cylinder is also replaced at the same time in most cases, so as to artificially shorten the service life of the rubber cylinder and increase the production cost. In the utility model, on the basis of the hydraulic rubber cylinder clamping disc, the slips, a slips seat and an end pressing cover are additionally arranged; when the slips with different specifications and sizes are replaced, only the end pressing cover needs to be taken down, and then the slips can be pulled out from the slips seat without disassembling the hydraulic clamping disc in an entire manner, so as to realize the purpose of quick replacing. With small overall size and low opening pressure, the hydraulic rubber cylinder clamping disc is beneficial for pressure coordination among branches of a hydraulic system, and meanwhile increases the efficiency ofthe hydraulic system; moreover, with the advantages of safe as well as reliable clamping work and small rotating inertia, the hydraulic rubber cylinder clamping disc can ensure coordinating actions when matching with a hydraulic clamp holder in the hydraulic system with the function of linkage.
Description
Technical field
The utility model 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.
The utility model content
It is a kind of when changing the slips of different specification size that the utility model provides, 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 utility model is with respect to prior art, and its advantage is as follows:
The utility model has been 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;
The utility model appearance and size 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.
