Abstract
The utility model provides a load bearing end strengthening device of a lifting lug of a suspension body, which is applicable to the fields of oil and geological well drilling. The strengthening device comprises a turret, a locking plate and nuts; an upper pin hole is arranged at the upper part of the turret and a lower pin hole is arranged on the lifting lug arranged at the lower part of the turret; and a connecting block is hinged in the upper pin hole arranged on the upper part of the turret by an upper connecting pin and is also hinged in the lower pin hole by a lower connecting pin. In normal work 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 prolong the service life of the lifting lug and lead the drilling work to be safer. With the strengthening device, the bearing capability of the lifting lug is improved, the replacement of lifting rings is convenient, and the structure of the strengthening device is simple.
Description
Technical field
The utility model belongs in oil, the geology a kind of suspension body hanger carrying end stiffening device in the drilling well field.
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 outside protection connecting rod only plays the effect that prevents the suspension ring slippage, and does not stress.When swiveling head bottom hanger had been subjected to the downward pulling force of suspension ring, swiveling head bottom hanger root produced 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 the suspension body hanger carrying end stiffening device in a kind of suitable oil, 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 following scheme in order to achieve the above object: comprise swiveling head, locking plate, nut, swiveling head top is provided with pin-and-hole, the hanger of swiveling head bottom is provided with down pin-and-hole, contiguous block by the hinge joint of last connecting pin swiveling head top be provided with in the pin-and-hole, contiguous block by connecting pin hinge joint down in pin-and-hole down.
Described connecting pin 3 down is the pyramid type pin, following connecting pin diameter is provided with screw thread than small end, the pyramid type hole of pin-and-hole for matching under the contiguous block with the pyramid type pin, the pyramid type hole of the following pin-and-hole that is provided with on the hanger of swiveling head bottom for matching with the pyramid type pin, contiguous block is by in the following pin-and-hole that the connecting pin hinge joint is provided with on the hanger of swiveling head bottom down, and following connecting pin diameter is equipped with locking plate, nut successively than small 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, increase the service life, make drilling well work safer.The hanger supporting capacity is strengthened.Make things convenient for the replacing of suspension ring, simple in structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is two of the present utility model and surveys schematic diagram.
The specific embodiment
As shown in the figure, suspension body hanger carrying end stiffening device, comprise swiveling head 4, locking plate 6, nut 7, swiveling head top is provided with pin-and-hole, the hanger of swiveling head bottom is provided with down pin-and-hole, contiguous block 2 by last connecting pin 1 hinge joint swiveling head top be provided with in the pin-and-hole, following connecting pin 3 is the pyramid type pin, following connecting pin diameter is provided with screw thread than small end, the pyramid type hole of pin-and-hole for matching under the contiguous block with the pyramid type pin, the pyramid type hole of the following pin-and-hole that is provided with on the hanger of swiveling head bottom for matching with the pyramid type pin, contiguous block is by the connecting pin hinge joint is in following pin-and-hole down, and following connecting pin diameter is equipped with locking plate successively than small end, nut.
Fastening by nut makes contiguous block and swiveling head bottom hanger be connected to an integral body, and swiveling head bottom hanger is when being subjected to suspension ring 5 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.
