Description
Technical field
This utility model relates to oil field drill oil derrick lifting device.
Background technology
At present, oil field derrick lifting device in the vertical direction has two kinds: a kind of is telescopic oil cylinder retractor device, is used for truck-mounted drilling rig.The derrick of this kind of structure, upper body is enclosed within down internal, promotes power by oil cylinder, make upper body under internal sliding, make derrick promote or retract.Another kind is rope system jack up unit, and this kind of structure is used for the stagewise derrick of upright suit, and this kind of many employing of derrick is spliced, with the lift headframe segmentation of rope system, carries one section and connects one section.In the face of the degree of depth reaches the derrick of 7000 meters, its telescopic oil cylinder telescopic mounting, oil cylinder can not meet the requirement promoting load, length of oil cylinder can not meet, and be inconvenient to that top is installed and drive, the upright sleeve type that hoists of rope system there is also dismounting trouble, it is impossible to the problems such as is put into.
Summary of the invention
The purpose of this utility model is in that to provide a kind of derrick retractor device, it be can meet large-scale suit stagewise derrick promote greatly tonnage demand and the derrick retractor device of easy accessibility.
nullThis utility model includes three joint sleeve type derricks、Upper end fixed pulley group、Lower end fixed pulley group、Derrick orienting roll wheels、Connect otic placode、Steel wire rope leading block group、Puffer and steel wire rope，The derrick epimere of three joint sleeve type derricks is sleeved in derrick hypomere after connecting derrick stage casing，Described derrick hypomere top cross-bar is connected to one and connects otic placode and a steel wire rope leading block group，Upper end fixed pulley group is connected on connection otic placode，Lower end fixed pulley group is connected to bottom derrick stage casing，In derrick orienting roll wheels are connected in derrick hypomere，Play on righting and guiding derrick、The effect that lower stage casing is slided，Puffer is fixed in the back side bottom derrick hypomere，Steel wire rope one end is connected on the cylinder of puffer，The other end of steel wire rope after steel wire rope leading block group then through after the fixed pulley group of lower end through upper end fixed pulley group，It is connected to after eventually passing lower end pulleys group on the fixing otic placode of steel wire rope at derrick hypomere top.
The wire rope handling order of its steel wire rope: the pulley (3-4) of (2-3)-lower end pulleys group of (3-3)-upper end assembly pulley of (2-2)-lower end pulleys group of pulley (the 3-2)-upper end assembly pulley of pulley (the 2-1)-lower end pulleys group of pulley (the 3-1)-upper end assembly pulley of the steel wire rope on puffer-steel wire rope leading block group-lower end pulleys group, finally fixes at the fixing otic placode of the steel wire rope at derrick hypomere A3 top.
Upper end assembly pulley is made up of 3 pulleys (2-1,2-2,2-3).
Lower end pulleys group (3) is made up of 4 pulleys (3-1,3-2,3-3,3-4).
Advantage of the present utility model is:
This utility model is reasonable in design compact, easy for installation.Owing to this utility model is arranged between the gap at derrick upper body and the lower body back side, entirely without interference in derrick opening, convenient top of installing is driven, and large-scale contraction derrick is very applicable.Especially the large-scale telescopic derrick used on more applicable ocean, can realize the retraction of derrick and fall, make derrick length and highly all reduce, and dismounts convenient transportation.

Detailed description of the invention
In conjunction with accompanying drawing embodiment, the utility model is described in further detail.
nullIn Fig. 1-5: derrick epimere A1 is connected with derrick stage casing A2，Derrick stage casing A2 is sleeved in derrick hypomere A3，The crossbeam at the top of derrick hypomere A3 is connected to one and connects otic placode 1，Upper end fixed pulley group 2 is connected on connection otic placode 1，Lower end fixed pulley group 3 is connected in the base cross members of derrick stage casing A2，Leading block group 4 is arranged in derrick hypomere A3，Puffer 6 connects derrick hypomere A3 back bottom，One end of steel wire rope 5 is fixed on puffer 6，The wire rope handling order of its steel wire rope 5: the pulley (3-4) of (2-3)-lower end pulleys group 3 of (3-3)-upper end assembly pulley 2 of (2-2)-lower end pulleys group 3 of pulley (the 3-2)-upper end assembly pulley 2 of pulley (the 2-1)-lower end pulleys group 3 of pulley (the 3-1)-upper end assembly pulley 2 of the steel wire rope 5-steel wire rope leading block group 7-lower end pulleys group 3 on puffer 6，The fixing otic placode 8 of the last steel wire rope at derrick hypomere A3 top is fixed.
When derrick needs to extend, starting puffer 6, steel wire rope 5 is retracted, and drives derrick epimere A1 to hoist by lower end pulleys group 3, and when derrick needs to retract, puffer 6 reverses, and derrick epimere A1 falls by deadweight, and the stopping means on derrick epimere A1 makes its return.In work process, whole device all operates in derrick epimere A1 and the direct gap of derrick hypomere A3, when hoisting, assembly pulley tilts certain angle, avoid producing friction, the guiding of derrick orienting roll wheels 4 and righting with derrick panel and diagonal brace and ensure derrick smooth sliding, will not rock.
