Summary of the invention
In order to solve above problem, the utility model provides a kind of novel single-stage fluid cylinder double lifting oil drilling, and concrete technical scheme is as follows:
A kind of single-stage fluid cylinder double lifting oil-well rig, comprise jack up unit, derrick, top layer, base, it is characterized in that, described derrick side is provided with derrick lifting chain lug seat and is connected with jack up unit one end, the wherein said jack up unit other end is connected with base by fluid cylinder rotating shaft, wherein said base is connected with middle level column to be connected by rotating shaft with top layer, wherein base is also provided with supplemental support post to be connected with top layer, wherein said top layer is provided with base hoist connect bearing be connected with derrick, described derrick is provided with rear support leg be connected with top layer by rear support.
Described jack up unit one end and base hoist and are connected bearing and are connected, and the fluid cylinder rotating shaft that the other end is preset in base is connected.
Described jack up unit is hoisted by connecting pin and derrick lifting engaging lug seat, fluid cylinder rotating shaft, base and is connected bearing and is connected.
Described derrick rear support leg is connected with the rear support be arranged on top layer by connecting pin.
Described middle level column is connected with top layer with base by connecting pin.
Described jack up unit comprises one group of fluid cylinder of symmetrically state centered by top layer, base.
Fluid cylinder undersetting is public pivot point, when transferring derrick when hoisting, and hoisting when transferring base, all using same undersetting.
Beneficial effect: the mode that hoists of pulley-steel wire rope-man-like shelf that a kind of single-stage of the utility model fluid cylinder double lifting oil-well rig is relatively traditional, enforcement of the present invention not only to have been omitted 3 to heavy assembly pulley and had been saved two groups of (4) cushion cylinders and respective pipeline control system, thus save buying and maintaining expense, reduce installation, dismounting time cost.After fluid cylinder retraction, undersetting is not disassembled, and allows fluid cylinder lie on support, meets modularization transport, effectively improves portability of drilling rig, have good value for applications.

Wherein: 1, low seat hoists and connects bearing 2, derrick 3, connecting pin 4, raising cylinder 5, middle level column 6, fluid cylinder rotating shaft 7, base 8, top layer 9, rear support 10, rear support leg 11, derrick lifting engaging lug seat 12, supplemental support post.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is done to the description of a nearly step.
A kind of single-stage fluid cylinder double lifting oil-well rig, comprise jack up unit, derrick 2, top layer 8, base 7, it is characterized in that, described derrick 2 side is provided with derrick lifting chain lug seat 11 and is connected with jack up unit one end, the wherein said jack up unit other end is connected with base 7 by fluid cylinder rotating shaft 6, wherein said base 7 is connected with middle level column 5 be connected by rotating shaft with top layer 8, wherein base is also provided with supplemental support post 12 to be connected with top layer 8, wherein said top layer 8 is provided with base hoist connect bearing 1 be connected with derrick 2, described derrick 2 is provided with rear support leg 10 be connected with top layer 8 by rear support 9.
Described jack up unit one end and base hoist and are connected bearing 1 and are connected, and the fluid cylinder rotating shaft 6 that the other end is preset in base 7 is connected.
Described jack up unit is hoisted by connecting pin 3 and derrick lifting engaging lug seat 11, fluid cylinder rotating shaft 6, base and is connected bearing 1 and is connected.
Described derrick rear support leg 10 is connected with the rear support be arranged on top layer by connecting pin.
Described middle level column 5 is connected with the rotating shaft on top layer 8 with base 7 by connecting pin.
Described jack up unit comprises one group of raising cylinder 4 of symmetrically state centered by top layer 8, base 7.
Operation principle:
Program a: derrick lifting
With reference to the accompanying drawings 1,2, squeeze into raising cylinder 4 top piston bar connecting pin 3 in derrick level, raising cylinder 4 and derrick lifting ear seat 11 are coupled together.Choose a fluid cylinder rotating shaft 6, both ensure fluid cylinder locating distance, after ensureing that again derrick base hoists and puts in place, fluid cylinder haul distance long enough.Two raising cylinders 4 being positioned at chassis interior start to stretch out by Hydraulic Station effect, and are slowly elected by derrick around fluid cylinder rotating shaft 6, and half-twist is erectility.Rear support 9 and rear support leg 10 are fixed by pin, derrick lifting completes.
Program b: base hoists
3,4 get connecting pin 3 and bounced back by raising cylinder 4 with reference to the accompanying drawings, the fluid cylinder 4 that adjusts hoisting aligns with connection bearing 1 hole of the base 7 that hoists, and squeezes into connecting pin 3, so far, and installing of fluid cylinder and base.Fluid cylinder when starting that hoists starts to stretch out by the effect of Hydraulic Station joystick, then base is slowly elected rising, and stop after driving middle level column half-twist to become erectility, and squeeze into the pin of fixing supplemental support 12, the base process of hoisting completes.
Concrete implementation step: play base 7 after first derrick raising 2, raising cylinder 4 top piston lever pin sub-aperture and derrick lifting engaging lug seat 11 are aligned, insert pin, start Hydraulic Station, manipulation joystick discharges air in cylinder, and then slowly injection liquid force feed makes raising cylinder derrick extending hoist to put in place, connect rear support leg 10 pin, now derrick 2 is in erectility, completes derrick lifting.
Being got by raising cylinder 4 top pins makes piston rod bounce back again, and piston rod and base is hoisted and be connected bearing 1 and connect with pin.Repeat aforesaid operations, raising cylinder lifting base is to operating position, and after squeezing into all connecting pins of supplemental support 12, the derrick base program that hoists all terminates.
