Abstract
The utility model provides a tensioner for a blowout preventer (BOP) of a self-elevating drilling platform, comprising a hydraulic control desk and a hydraulic cylinder, wherein the hydraulic cylinder is respectively connected with a drill table reverse top and the BOP via shackles; meanwhile, the energy accumulator of the hydraulic control desk is connected with the hydraulic cylinder via a hydraulic oil pipe; and the hydraulic cylinder is connected with the pipeline on the hydraulic control desk via another hydraulic oil pipe. After the scheme is adopted, the tensioner for the BOP of the self-elevating drilling platform has the advantages that the weight of the BOP per se can be transferred to the tensioner when the BOP works, the pressure of a drill rod in work is reduced, the safety of the BOP is improved, the BOP loaded synchronous tension force is provided, and the overloading condition of top drive equipment caused by change of external loads is prevented.
Description
Technical field
The utility model relates to the technical field of offshore boring island auxiliary equipment, refers in particular to the tensioner that a kind of preventer BOP of self-elevating drilling platform uses.
Background technology
Convention in the industry; The existing preventer (BOP) that is used for self-elevating drilling platform all is to adopt the direct and anti-top of the rig floor ways of connecting through wire rope, but because preventer will bear variable load, so above mode is as easy as rolling off a log wire rope is broken; There is potential safety hazard in poor reliability.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, the tensioner that provides a kind of preventer BOP of simple, safe and reliable self-elevating drilling platform rational in infrastructure to use.
For realizing above-mentioned purpose; The technical scheme that the utility model provided is: the tensioner that a kind of preventer BOP of self-elevating drilling platform uses; It includes hydraulic control panel and hydraulic cylinder, wherein, described hydraulic cylinder through shackle instead push up with rig floor respectively, preventer is connected; Simultaneously the accumulator of hydraulic control panel is connected with this hydraulic cylinder through hydraulic oil pipe, and this hydraulic cylinder is connected with pipeline on the hydraulic control panel through other hydraulic oil pipe.
The utility model is after having adopted such scheme; Its great advantage be the utility model can be when preventer be worked with the preventer own wt transfer to from one's body; Pressure when alleviating drilling rod work; Strengthened the safety of preventer, provide simultaneously and the synchronous pulling force of preventer stand under load, prevented that external load from changing and cause the situation of top drive apparatus overload.
Description of drawings
Fig. 1 is the axonometric drawing of the utility model.
Fig. 2 is the sketch map of the utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described further.
Shown in accompanying drawing 1 and accompanying drawing 2; The tensioner that the preventer BOP of the described self-elevating drilling platform of present embodiment uses; It includes hydraulic control panel 1, two hydraulic cylinders 2; Wherein, Described these two hydraulic cylinders 2 through shackle all instead push up with rig floor, preventer is connected, hydraulic oil pipe 3 and this 2 corresponding joining of two hydraulic cylinders through separately respectively of two accumulator 1-1 in the hydraulic control panel 1 simultaneously, and these two hydraulic cylinders 2 are connected through the pipeline of other separately hydraulic oil pipe 4 with hydraulic control panel 1 respectively again.During work; The utility model mainly is the duty with withdrawal and oil cylinder of stretching out through two hydraulic cylinders 2 of hydraulic control panel 1 control; Control corresponding hydraulic cylinder 2 through two accumulator 1-1 in this hydraulic control panel 1 simultaneously and under the stand under load different state, keep constant compression force, reach instructions for use.After using this tensioner; The existing preventer (BOP) that is used for self-elevating drilling platform can directly have been avoided the drawback that in the past existed; During work own wt is transferred on this tensioner, the pressure when alleviating drilling rod work has also strengthened the safety of itself.This tensioner provides and the synchronous pulling force of preventer stand under load simultaneously, prevents that external load from changing and causing the situation that top drive apparatus transships, and the security reliability height is worthy to be popularized.
The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.
