Description
Technical field
The present invention relates to a kind of oil drilling equipment.
Background technology
Petroleum rig base for installing derrick, winch, rotating disk, putting drilling rod and rig tool etc., and provides the installing space of wellhead assembly and the operating platform of drillng operation.Current deep-well petroleum rig application is increasingly extensive, deep drilling rig General Requirements provides larger well head space, to meet well head mounting shaft Ore-controlling Role, thus the requirement of the safety of down-hole when improving drillng operation, thus rig substructure daylight opening DLO ground level generally can not be less than 7.5 meters, most of rig substructure daylight opening DLO ground level is all between 9.5 to 10.5 meters, and deep drilling rig base adopts the conventional mounting methods such as crane installation to be difficult to meet the demands.Therefore the existing many Bian of deep drilling rig base reinstate with derrick one form of structure that winch hoists or fall, when hoisting or fall, there is speed instability and easily form impact load, derrick base is caused to play the large problem of load up, simultaneously owing to playing load up considerably beyond live load, for having met the requirement of strength of load up, complex structure during base designs, weight have increased, and the increase of base weight brings again the increase of manufactures, installation and cost of transportation.Excessive load up also causes certain hidden danger to safety in production.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is the oil drilling equipment providing a kind of practicality, hoists to fall to stablizing, structure is simple, lighter in weight.
For reaching above-described object, a kind of oil drilling equipment of the present invention takes following technical scheme:
A kind of oil drilling equipment, comprise rig floor body and elevating mechanism, it is characterized in that, the column of described rig floor body is the twin columns frame construction connected by cross bar, rig floor body is by upper table surface, pedestal and four columns be hinged between upper table surface corner and pedestal are formed, described elevating mechanism is by an identical symmetrically arranged left side, right lifting gear composition, a described left side, right lifting gear comprises multi-stage expansion hydraulic cylinder and follow-up telescoping strut, described multi-stage expansion hydraulic cylinder is between two bars of follow-up telescoping strut, multi-stage expansion hydraulic cylinder and follow-up telescoping strut is cross-shaped is hinged between upper table surface and pedestal, described follow-up telescoping strut is the double-rod structure connected by Heng Defend, in follow-up telescoping strut is, outer tube sleeve assembling structure, described interior pipe has when upper table surface rise rise to extreme higher position time limit in pipe continue retraction spacing shoulder, interior pipe has the dowel hole that corresponding upper table surface rises and falls two positions when putting in place, described outer tube have the dowel hole corresponding with interior pipe dowel hole.
Dowel hole between described inner and outer pipe is built with alignment pin.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
Made the derrick being arranged on rig floor body upper table surface do parallelogram displacement with upper table surface to hoist by the effect of multi-stage expansion hydraulic cylinder, follow-up telescoping strut upper table surface hoist put in place after limit its continue displacement, follow-up telescoping strut penetrates alignment pin, and base is just in steady-working state.Base hoists steadily, and the process that hoists, without impact load, plays load up little, and base designs structure is simple, and weight is relatively light.Hoist with in dropping process, operating personnel carry out Long-distance Control by hydraulic system, and rig floor does not need operating personnel, improve safety guarantee, floor installation is quick, relatively light, the rapid transporting of rig can be realized, reduce the manufacture of rig substructure, installation and cost of transportation.

Detailed description of the invention
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, a kind of oil drilling equipment of the present invention, be made up of rig floor body and elevating mechanism, rig floor body is by upper table surface 1, pedestal 2 and four columns 3 be hinged between upper table surface 1 four jiaos and pedestal 2 are formed, column 3 is the twin columns frame construction connected by cross bar, elevating mechanism is by an identical left side, right symmetrically arranged a pair lifting gear composition, each lifting gear is made up of multi-stage expansion hydraulic cylinder 4 and follow-up telescoping strut 5, multi-stage expansion hydraulic cylinder 4 tilts to be hinged between upper table surface 1 and pedestal 2, follow-up telescoping strut 5 is in two, the double-rod structure that the single pole that outer tube is set with is connected into by cross bar, follow-up telescoping strut 5 and multi-stage expansion hydraulic cylinder 4 is cross-shaped is hinged between upper table surface 1 and pedestal 2, multi-stage expansion hydraulic cylinder 4 is positioned in the middle of two bars of follow-up telescoping strut 5, the interior pipe 5a of follow-up telescoping strut 5 has when upper table surface 1 rises to extreme higher position and operating position limit in pipe 5a continue in outer tube 5b retraction spacing shoulder 5c, interior pipe 5a has the dowel hole that corresponding upper table surface 1 rose and fell two positions when putting in place, outer tube 5b have the dowel hole corresponding with the dowel hole of interior pipe 5a, in, dowel hole between outer tube is built with alignment pin 6, upper table surface 1 is provided with derrick 7.Upper table surface, for installing derrick, the deadweight of hook load when bearing drillng operation, derrick, is deposited drilling well-head instrument and is provided Active workings for drillng operation personnel.The dynamic changes process that pedestal is used for upper table surface during drillng operation to be subject to is to basis.Column is used for upper table surface and pedestal to couple together, and provides the operation height of large space, meets the requirement of headway during drillng operation.
Installation process of the present invention: be full state before drillingrig base transport and installation, after the installation of derrick low level is carried out in well site, is risen derrick entirety by the winch of rig, derrick is uprightly fixedly mounted on base upper table surface.Synchronous manipulation is left, right multi-stage expansion hydraulic cylinder piston stretches out, multi-stage expansion hydraulic cylinder applies the active force in direction, upper right side to upper table surface, make upper table surface do parallelogram displacement together with derrick to upper right side to hoist, follow-up telescoping strut is retracted in outer tube with the pipe in it that hoists of upper table surface, when upper table surface is moved to extreme higher position and operating position, in locating shoulder on the interior pipe of follow-up telescoping strut limits, pipe continues to retract, thus limit upper table surface continuation displacement, control multi-stage expansion hydraulic cylinder piston to stop stretching out simultaneously, alignment pin is penetrated between the internal and external casing of follow-up telescoping strut, base is just in steady-working state.
Unloading process of the present invention: under base vertical working state, remove the internal and external casing alignment pin of follow-up telescoping strut, handle multi-stage expansion liquid cylinder piston to retract, upper table surface and derrick are under the effect of gravity and multi-stage expansion hydraulic cylinder piston, parallelogram displacement is done in below left, until drop to the lowering position of upper table surface, multi-stage expansion hydraulic cylinder quits work, between the internal and external casing of follow-up telescoping strut, penetrate alignment pin, base is in transport and state before installing.
