Abstract
The utility model provides a load bearing strengthening device for a lifting lug of a top drive turret, which is applicable to the fields of oil and geological well drilling. The load bearing strengthening device comprises the turret; a pin hole is arranged at the upper part of the turret and a lifting lug is arranged at the lower part of the turret; an inner hole is arranged at one end of a connecting rod and the other end thereof is provided with threads; a U-shaped groove is arranged at the outer end of the lifting lug at the lower part of the turret; the connecting rod is hinged in the pin hole at the upper part of the turret by a connecting pin; and the end provided with threads of the connecting rod is positioned in the U-shaped groove of the lifting lug at the lower part of the turret; a spacer, a locking plate and a nut are sequentially arranged at the end provided with threads of the connecting rod; and the nut is matched with the threads. In normal operation of drilling machines, the strengthening device can effectively alleviate the stress focusing on the root of the lifting lug at the lower part of the turret so as to lead the drilling work to be safer; and the load bearing capability of the lifting lug can be strengthened and the connecting is reliable; and the load bearing strengthening device has reliable connection and simple structure, thus facilitating the replacement of lifting rings.
Description
Technical field
The utility model belongs to a kind of top refoulement rotary head hanger carrying stiffening device in the drilling well field in oil, the geology.
Background technology
At present, refoulement rotary head bottom, top hanger is when being subjected to the downward pulling force of suspension ring, and swiveling head bottom hanger force-bearing situation is a cantilever support, and outer lateral connector bar spare only plays the effect that prevents the suspension ring slippage, and does not stress.Swiveling head bottom hanger is when being subjected to the downward pulling force of suspension ring, and swiveling head bottom hanger root produces very big stress and concentrates.In the large-tonnage design, be difficult to reach due safety factor.
The utility model content
The purpose of this utility model is to provide top refoulement rotary head hanger carrying stiffening device in a kind of suitable oil, the geological drilling field, in the process of rig operate as normal, can effectively alleviate swiveling head bottom hanger Root Stress and concentrate situation.The hanger supporting capacity is strengthened, and increases the service life.Make drilling well work safer.
Adopt technical scheme in order to achieve the above object: comprise swiveling head, swiveling head top is provided with pin-and-hole, the swiveling head bottom is provided with hanger, one end of connecting rod is provided with an endoporus, the other end is provided with screw thread, hanger outer end, swiveling head bottom is provided with U type groove, connecting rod links in the pin-and-hole on swiveling head top by connecting pin, connecting rod is provided with the U type groove that a threaded end is positioned at swiveling head bottom hanger, connecting rod is provided with a threaded end pad, locking plate, nut is installed successively, nut and threads engaged.
Bottom, described hanger outer end is provided with draw-in groove, and pad is installed in the draw-in groove of bottom, hanger outer end.
Advantage of the present utility model is: in the process of rig operate as normal, can effectively alleviate swiveling head bottom hanger Root Stress and concentrate situation, make drilling well work safer.The hanger supporting capacity is strengthened.Connect reliably, simple in structure, make things convenient for the replacing of suspension ring.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that axle of the present utility model is surveyed schematic diagram.
The specific embodiment
As shown in the figure, top refoulement rotary head hanger carrying stiffening device, comprise swiveling head 6, swiveling head top is provided with pin-and-hole, the swiveling head bottom is provided with hanger, it is characterized in that: an end of connecting rod 2 is provided with an endoporus, the other end is provided with screw thread, hanger outer end, swiveling head bottom is provided with U type groove, connecting rod links in the pin-and-hole on swiveling head top by connecting pin 1, connecting rod is provided with the U type groove that a threaded end is positioned at swiveling head bottom hanger, and connecting rod is provided with a threaded end pad 3, locking plate 4, nut 5, nut and threads engaged are installed successively.Bottom, hanger outer end is provided with draw-in groove, and pad is installed in the draw-in groove of bottom, hanger outer end.
Fastening by nut makes pad contact and compress with swiveling head bottom hanger, and swiveling head bottom hanger is when being subjected to suspension ring 7 downward pulling force, and swiveling head bottom hanger is the two ends fixed support, alleviates swiveling head bottom hanger Root Stress greatly and concentrates situation.Force-bearing situation is significantly improved, and the hanger supporting capacity is strengthened, and increases the service life.
