Description
Technical field
The present invention relates to oil and gas well drilling field, particularly one kind three to save hydraulically extensible suit derrick.
Background technology
The derrick that domestic petroleum industry truck-mounted drilling rig is equipped with present is the mast shape open-front tower with the rope that jumps mostly, and two save hydraulic pressure
It is flexible, derrick small angle inclination.Derrick hypomere upper end and a total of 12 of overhead traveling crane and quadruple board platform, which jump to restrict, to be connected, and the rope that jumps is to well
Frame provides stability force, and spring rope structure is needed in the large number of ground anchor pit of ground configuration to provide support reaction, and the every rope that jumps needs
Hanging degree is adjusted, larger human error be present, causes spring rope unbalance stress to cause derrick unbalance stress.Due to using the rope that jumps
Structure, if increase clear derrick height, meet three section thribble requirements, every section of derrick is required for spring rope stable, can so caused
The rope quantity that jumps further increases, and the increase of derrick paragraph number, and unbalance stress can have a strong impact on the stability of derrick, so traditional vehicle
Carry derrick and be designed as two nodule structures, effective depth is 38 meters.The type derrick bulk is small, and traveling system is transported outside derrick
OK.Due to height-limited, the type safety platform can only discharge binodal drilling rod, cause drillng operation, lower driller's condition to take
It is longer, it is less efficient, and the installation for pushing up drive system is inconvenient, so that rig does not possess stronger down-hole accident disposal ability.
The content of the invention
The problem of existing for prior art, goal of the invention of the invention are to provide a kind of more intelligent, satisfaction more
Duty requirements, convenience in transport and placement, improve drillng operation efficiency, scientific structure, stable three section hydraulically extensible suit derricks.
To achieve these goals, the technical solution adopted by the present invention is：
One kind three saves hydraulically extensible suit derrick, and its derrick geometry form is K shape open fronts, is provided with derrick for turning
Become some oil cylinders of the various working conditions of derrick, quadruple board platform is installed in front of derrick, derrick rear, side are provided with oil cylinder righting
Device, the derrick are divided into three sections, respectively derrick epimere, derrick stage casing, derrick hypomere, and derrick epimere coordinates in derrick stage casing
Wall, derrick stage casing, which coordinates to be provided with derrick hypomere inwall, derrick, can make derrick keep extended state and can be long-range
The bogey of control, all oil cylinders on derrick being capable of remote control；Derrick uses three sections of stretching structures, makes derrick full
More convenient transport and placement while foot more duty requirements, also clear derrick height greatly promotes, the quadruple board platform energy on derrick
The enough section of discharge three drilling rods, reduce drillng operation, lower driller's condition takes, raising efficiency；Bogey and in addition to bogey
All oil cylinders can remote control make derrick more intelligent, prior art mast shape cantilever mast be with jump rope beat earth anchor
Can be stable, this derrick is K shape open fronts, and without jumping, rope just can be stable.
As the preferred scheme of the present invention, the derrick epimere is provided with for lower derrick epimere limit of derrick extended state
Bogey A of the position on derrick stage casing, the derrick hypomere is provided with spacing for lower derrick stage casing of derrick extended state
Bogey B on derrick hypomere；Being provided with the bogey A can be turned to above the crossbeam of derrick stage casing both sides
Carrier block, the carrier block that can be turned to derrick stage casing both sides below the crossbeam is provided with the bogey B；By tilting out
Carrier block, carrier block is set to be stuck between each crossbeam, derrick reaches steady operation under the deadweight in derrick epimere Yu derrick stage casing
State.
As the preferred scheme of the present invention, the oil cylinder centralizer is separately mounted to derrick stage casing, the side of derrick hypomere
Crossbeam and rear below the crossbeam, it is made up of centralizing bracket, torsion spring, is set installed in the centralizing bracket front end of rear below the crossbeam
Roller is equipped with, the centralizing bracket is ejected under derrick extended state and coordinated on the piston rod of corresponding jacking cylinder；Oil cylinder is helped
The setting of positive device effectively prevents the radially bending of the jacking cylinder under derrick extended state.
As the preferred scheme of the present invention, the quadruple board platform is arranged in front of the derrick stage casing, and quadruple board platform is used to discharge
