The floating male joint body is fixed to one end of the floating spline sleeve through a bolt; the floating female joint body is sleeved with the floating spline sleeve; the inner wall of the floating spline sleeve and the outer wall of the floating female joint body are each provided with a limiting structure, and the limiting structures are matched with each other; the shock absorbing pad is further fixed to the end face of the end, close to the floating male joint body, of the floating female joint body; a gap is formed between the shock absorbing pad and the floating male joint body; and the floating spline sleeve and the floating female joint body are in transmission through an involute spline pair. The floating joint has the beneficial effects that torque is transmitted, a gyrator transmits power to the floating male joint body, power is transmitted to the floating spline sleeve through the bolt, then the power is transmitted to the floating female joint body through the involute spline pair, and accordingly the power is transmitted to a drill pipe.
Description
Technical field
The invention belongs to drilling equipment field, mine, particularly relate to a kind of floating junction.
Background technology
Floating junction is parts with bar drill car indispensability of automatically unloading, and it is to connect gyrator and the tie of drilling rod.In the market gyrator be connected usually rigid structure with drilling rod, such structure is when stacks, and the screw thread easily causing drilling rod is damaged by pressure by slew gear or propulsive mechanism.
Summary of the invention
In order to solve above-mentioned technical problem, it is an object of the invention to provide a kind of simple in construction, and there is the floating junction of floating compensation function and cushioning effect.
To achieve these goals, present invention employs following technical scheme:
A kind of floating junction, including floating female joint, floating male joint, floating spline housing and beam, described floating male joint is fixed by bolt with one end of floating spline housing, described floating spline housing is set in the outside of floating female joint, and it is respectively equipped with, with on the outer wall of floating female joint, the position limiting structure cooperated on floating spline housing inwall, described floating female joint is further fixed on beam on the end face of floating male joint one end, it is provided with gap between described beam and floating male joint, by involute spline auxiliary driving between described floating spline housing and floating female joint.
Preferably: between described floating female joint and floating male joint, be also associated with guide pipe, the two ends of described guide pipe are plugged between floating female joint and floating male joint respectively, and guide pipe and the endoporus of floating female joint, floating male joint endoporus between form closed conduit.Such structure makes floating junction also have the effect of conveying high-pressure gas.
Preferably: on the inwall of described floating female joint and floating male joint one end close to each other, be embedded with sealing ring respectively.
Preferably: described sealing ring uses Yx sealing ring.
Preferably: the other end of described floating spline housing is fixed with between dustproof gland, and dustproof gland and floating female joint also by bolt and is additionally provided with dust ring.
Preferably: between described bolt and floating spline housing, be additionally provided with packing ring.
Advantages of the present invention and beneficial effect:
1, transmission moment of torsion, gyrator passes to floating male joint power, by bolt, power is passed to floating spline housing, then by involute spline pair, power is passed to floating female joint, and then passes to drilling rod.
2, floating compensation function, when stacks, according to the position of bottom drilling rod tailing screw flight, floating junction can correspondingly fluctuate a distance, so that threaded portion correctly screws.This structure, slew gear when also can avoid stacks, propulsive mechanism damage the screw thread of drilling rod by pressure.
3, cushioning effect, under the effect of propulsive force, floating female joint upper surface is pressed on the lower surface of floating male joint by beam, and drilling rod, coming on impactor high-frequency percussion wave loops, owing to beam has the effect of absorption energy, and then protects gyrator.
