Abstract
The utility model discloses a large operating space telescopic mast used for a mast in the oilfield well drilling. The utility model is formed by connection of two segments of large section telescopic n-shaped frames. Each segment of mast comprises an upright post, a cross beam and an oblique draw rod, wherein the lower part of the mast is in a spacious Y-shaped structure; a bearing pin is pushed to enter and go out by a direct pushing type promotional cylinder (7) between the upper segment (2) of the mast and the lower segment (3) of the mast; after the mast is lifted, the upright posts of the upper segment (2) of the mast and the lower segment (3) of the mast are fixed by a U-shaped bolt (11) which can be turned over. A dead rope device capstan (9) is arranged on the lower segment of the mast. The large section structure which is innovatively designed is used by the utility model, and the Y-shaped form on the lower part is matched; thus, the working space around a wellhead is improved, the use safety is improved and the accident potential can be reduced.
Description
Technical field
The utility model relates to a kind of oil-well drilling equipment, particularly a kind of Drilling derrick.
Background technology
In existing lightweight rig, what derrick adopted is a kind of small bore telescopic " ∏ " type structure.In order to satisfy need of work, the derrick hypomere is an enclosed construction in both sides, rig floor face place.It is less to add the derrick cross section, and working space is less around the well head, and Type B tongs worker is prone to accidents when doing, and when being in an emergency, passway for escaping is not really unimpeded, has accident potential.
Summary of the invention
The purpose of this utility model provides a kind of big operating space telescope pole, to overcome the shortcoming of prior art.
Specifically, a kind of big operating space telescope pole, it is to be connected and composed by two sections telescopic " door " font rigid frame derrick epimeres (2) and derrick hypomere (3), every section derrick is formed by connecting by column, crossbeam, diagonal member, " people " font working space that derrick hypomere (2) bottom adopts oblique column (6) and drag link to form; Turnover and derrick by direct-push distribution cylinder (7) promotion bearing pins between derrick epimere (2) and the derrick hypomere (3) rise between back derrick epimere (2) and derrick hypomere (3) column fastening with turning U-bolt (11); Dead line device capstan winch (9) is installed on the derrick hypomere.
The utility model since derrick epimere and hypomere form by heavy in section " door " font space steel frame, adopt oblique column and drag link to form " people " font structure in derrick hypomere bottom, this structure has satisfied intensity, rigidity and the stability requirement of derrick, increased well head working space on every side, the open visual field, reduced accident potential, the good operation condition is provided.
Description of drawings
Fig. 1 is the utility model structural representation (derrick hoists preceding).
Fig. 2 is the utility model structural representation (derrick hoists back).
Fig. 3 is the utility model structural representation (before derrick is flexible).
Fig. 4 is the utility model structural representation (the flexible back of derrick).
The figure number explanation
1---quadruple board platform; 2---the derrick epimere; 3---lifting bracket; 4---the derrick hypomere; 5---raising cylinder; 6---preceding oblique column; 7---locking cylinder; 8---telescoping mechanism; 9---dead line device capstan winch; 10---ladder; 11---turning U-bolt.
The specific embodiment
Below in conjunction with accompanying drawing the utility model being done one describes in detail.Derrick epimere (2) and hypomere (4) are formed by heavy in section " door " word (" ∏ " type) type space steel frame, adopt oblique column (6) and drag link to form " people " font structure in derrick hypomere bottom, this structure has satisfied intensity, rigidity and the stability requirement of derrick, increased well head working space on every side, the open visual field, reduced accident potential, the good operation condition is provided.
Bearing pins on the derrick between the hypomere is the direct-push structure, is pushed by cylinder (preface 7) and pulls out locking, and performance simple in structure is reliable.Derrick raising cylinder (5) lower fulcrum is adjusted platform height and need do not dismantled fluid cylinder on the liftable base seat of honour.Be turning U-bolt (preface 11) locking between the hypomere on the derrick, easy to operate, the radius of gyration is little during upset.Dead line device (9) is fixed on the derrick hypomere behind, and tourist bus can transport with derrick, has realized that the rig removal of home do not dismantle the trip rope.
Claims (1)
1, a kind of big operating space telescope pole, it is characterized in that connecting and composing by two sections telescopic " door " font rigid frame derrick epimeres (2) and derrick hypomere (3), every section derrick is formed by connecting by column, crossbeam, diagonal member, " people " font working space that derrick hypomere (2) bottom adopts oblique column (6) and drag link to form; Turnover and derrick by direct-push distribution cylinder (7) promotion bearing pins between derrick epimere (2) and the derrick hypomere (3) rise between back derrick epimere (2) and derrick hypomere (3) column fastening with turning U-bolt (11); Dead line device capstan winch (9) is installed on the derrick hypomere.
