This derrick is compared to have with the derrick in other known technology, A shape derrick, two-piece type K shape derrick the advantage time saving and energy saving, that installing space is little, movement length is little is installed, with mast shape derrick compare need not use guy wire keep stability, thereby has a certain advance, but limited by traffic condition, it is little that shelves are opened in its derrick bottom, be generally 3～3.3m, cause the well head operating space little.Carry out machinery when hoisting when derrick utilizes rig (workover rig) to carry winch with wire rope, the man-like shelf that must configure dedicated hoists after having hoisted, must shed this man-like shelf, complicated operation.
When known derrick adopted the hydraulically extensible epimere, the hydraulic cylinder top was fixed on the crossbeam that hoists, and the fluid cylinder head seal can't be safeguarded, hydraulic cylinder bottom piston rod directly is fixed on the derrick hypomere and hoists on the beam, and fluid cylinder can't be extracted out from derrick is inner, when liquid cylinder entity is safeguarded, must unload whole derrick earlier, very inconvenient, especially for ocean platform, be subjected to the platform area constraints, sometimes can't realize at all, need special vessel to transport to the land maintenance of going, cost dearly, delay work and cause delay.
Known derrick middle sleeve stabbing board is not with guide rail, is stationary structure, can not adapt to the sleeve pipe requirement of different size.Adopt a plurality of installation sites, but the operation effort is time-consuming, very inconvenient for this reason.
The utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model provides quick for installation, convenient, safety; It is big that shelves are opened in the derrick bottom, can be designed to 4～5m; Realize safeguarding on the spot; The hydraulic elevation type drilling derrick of sleeve pipe stabbing board stepless speed changing adjustment.
The technical solution adopted in the utility model is: the hydraulic elevation type workover rig derrick, by the derrick epimere, the derrick hypomere, form with extending cylinder, in addition, also comprise: hydraulic cylinder top holder, the cylinder lower holder, base, connect bearing pin, stepless adjustable sleeve pipe stabbing board, the derrick epimere is sleeved in the derrick hypomere, the derrick hypomere is connected on the derrick base by connecting bearing pin, the derrick base cross section is greater than derrick hypomere cross section, and the derrick base foreleg turns forward, the load carrier of derrick hypomere is realized the support to the derrick epimere, and telescopic hydraulic cylinder is by hydraulic cylinder top holder, the cylinder lower holder is separately fixed on derrick epimere and the derrick hypomere.
Above-mentioned derrick base is provided with two monolithics that are welded by rectangular steel pipe or angle steel, and described foreleg adopts i iron or H shape steel or assembly welding beam, and two monolithics are connected with the back leg truss of foreleg, derrick base respectively by bearing pin.
Above-mentioned hydraulic cylinder top holder is made up of clamp, gusset, fixed head, gusset.
Above-mentioned cylinder lower holder is made up of riser, the pin that can pull out, connection base plate.
The setting of described sleeve pipe stabbing board is made up of electric block, lift rope, guide rail, slide block, pedal assembly, realizes the operating desk main body is carried out elevator and stepless location.
The hydraulic elevation type workover rig derrick that the utility model provides can bring following effect:
Owing to adopt understructure, thereby the utility model is not subjected to transport restrictions, and it is big that shelves are opened in the derrick bottom; The cancellation man-like shelf, quick for installation, convenient, safety.
Because adopt hydraulic cylinder top holder, cylinder lower fixed seat structure, the telescopic hydraulic cylinder top is an Open architecture, after the pin that can pull out is removed in the telescopic hydraulic cylinder bottom, also become Open architecture, two all can be extracted out, can realize safeguarding on the spot, and is easy to maintenance.
Owing to adopt stepless adjustable sleeve pipe stabbing board 12 and guide rail, can adapt to the sleeve pipe requirement of different size.
