Abstract
The present invention relates to the slip assemblies on a kind of full-hydraulic power head drill rubber oild chuck.Comprise slips (1), regulating fender (2) and spring (3), before and after described slips (1), both sides are provided with four square grooves, and upper and lower both sides are provided with two groups of cylinder holes; Before and after described regulating fender (2), both sides are provided with two square boss; Described spring (3) has four groups, is arranged on respectively in two groups of cylinder holes of adjacent two slips (1), makes four slips (1) become cylindric integral installation in packing element.During chucking work, regulating fender moves radially slips and play the guiding role, and significantly can reduce the wearing and tearing of packing element and slips, reduces non-cutting time, reduces operating cost, improves system effectiveness.
Description
Technical field
The present invention relates to a kind of gripping mechanism, belong to boring mechanic field, be specifically related to the slip assemblies on a kind of full-hydraulic power head drill rubber oild chuck.
Background technology
Chuck is one of full-hydraulic power head drill independently vitals, its function is clamping drilling rod, and to drilling rod transmitting torque and axial force, drilling tool is driven to realize revolution and feed, and auxiliary movement during accident settlement, also can match with clamper and there is stubborn, to unload drilling rod and lifting (or removing) drilling tool function.The condition of work of chuck is severe, must bear the maximum axial load of rig and maximum flywheel moment, and act frequently.The performance of chuck directly has influence on the efficiency and quality of creeping into.
At present, the form of structure of oild chuck adopts most often rubber.The main manifestations that rubber oild chuck lost efficacy is the wearing and tearing of packing element and slips, and change packing element and be different from slips and miscellaneous part, need chuck integral demounting, each parts are ressembled, and non-cutting time is long, and operating cost is high, have a strong impact on system effectiveness.
Summary of the invention
For above-mentioned deficiency, the object of the present invention is to provide the rubber oild chuck slip assemblies that a kind of structure is simple, easy to process, very easily assemble.
For realizing object of the present invention, the technical scheme that the application takes is as follows:
Rubber oild chuck slip assemblies of the present invention, is made up of slips, regulating fender and spring.Before and after described slips, both sides are provided with four square grooves, and upper and lower both sides are provided with two groups of cylinder holes; Before and after described regulating fender, both sides are provided with two square boss.
Described spring has four groups, is arranged on respectively in two groups of cylinder holes of adjacent two slips, makes four slips become cylindric integral installation in packing element.
The square boss of described regulating fender is arranged in the square groove of slips.
The fit clearance 2b ensureing slips movement is flexibly provided with between described slips and regulating fender, and slips joint open a.
The diameter dimension Φ of described slips is the one in the plurality of specifications drilling rod of slips clamping.
Beneficial effect:
The present invention can significantly improve the life-span of packing element on full-hydraulic power head drill rubber oild chuck and slips, reduces fault time, reduces operating cost, improves drilling efficiency;
Slips of the present invention and regulating fender coordinate to be installed, and its advantage is that the circumference mutually limiting the other side is collected together and slides axially;
Regulating fender of the present invention moves radially slips when chucking work and play the guiding role;
Slips of the present invention under the action of the spring, can automatically reset along the guiding of regulating fender, effectively reduces the wearing and tearing of slips to drilling tool;
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is left pseudosection of the present invention.
Wherein, 1 is slips; 2 is regulating fenders; 3 is springs.Size a is slips joint open; B is the gap of slips and regulating fender; Φ is drill pipe diameter.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
See Fig. 1,2, rubber oild chuck slip assemblies of the present invention, comprises slips 1, regulating fender 2 and spring 3.Before and after described slips 1, both sides are provided with four square grooves, and upper and lower both sides are provided with two groups of cylinder holes; Before and after described regulating fender 2, both sides are provided with two square boss; Described spring 3 has four groups, is arranged on respectively in two groups of cylinder holes of adjacent two slips 1, makes four cylindric integral installations of slips 1 one-tenth in packing element; The square boss of described regulating fender 2 is arranged in the square groove of slips 1; Be provided with the fit clearance 2b ensureing slips movement flexibly between described slips 1 and regulating fender 2, and be not less than a.
Last it is noted that obviously, above-described embodiment is only for the application's example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments, and thus the apparent change of amplifying out or variation be still among the protection domain of the application's type.
