Abstract
The utility model discloses a boring tower which is used for boring deep well, comprising a well rack, an overhead crane, a racking platform, a vertical tube platform, a work ladder and a base seat. The well rack is provided with four main tower posts. The left side, the right side and the back side of the well rack are integrated into a whole through the four main tower posts. The upper segment of the front side of the well rack is connected with a truss, while the lower segment takes a front opening structure. The cross section of the lower segment of the well rack takes an open n-shaped space structure so that the drill rod and the vertical root can pass through. A herringbone-shaped lifting rack which is used for lifting and laying the well rack horizontally is arranged between the base seat positioned at the back of the well rack and the well rack. The utility model has the advantages that the n-shaped structure formed by the four main tower posts increases the operation space inside the well boring tower and increase the stability of the boring tower; and the top segment of the boring tower is made into a closed space frame structure, and the four sides of the structure is connected with a truss, thereby increasing the stability of the whole device. Besides, the whole boring tower is designed into a truss structure with five segments, which is convenient for mounting and demounting and is also convenient for transporting.
Description
Technical field
The utility model relates to a kind of a kind of boring tower that drills for oil and use when well or other deep-well.
Background technology
The A font structure derrick that the boring tower of the at present general usefulness that drills for oil all is made up of three king-posts.The latter half of headframe has only two faces to be provided with drag link and the diagonal member that connects king-post, and syndeton is not very stable.Spatial content is smaller in the boring tower that other three king-posts are formed, tower, deposits the limited amount of drilling rod, and boring tower is generally overall structure, install and transportation very inconvenient.
Summary of the invention
The technical problems to be solved in the utility model provides that a kind of Stability Analysis of Structures, spatial content are big, the boring tower of easy accessibility.
The technical scheme in the invention for solving the above technical problem is:
Comprise derrick, overhead traveling crane, quadruple board platform, standpipe platform, working stand, man-like shelf, base, the king-tower post of derrick has four, and left and right, back three of derrick connect as one four king-tower posts by truss.This derrick is the open front formula, and cross section is a not enclosure space structure of ∏ type.Be provided with on the base at derrick rear and between the derrick and rise and set level the herringbone hoisting rack that derrick is used.
Further improvement of the utility model is: the epimere in the derrick front also has truss to connect, and hypomere is that three of open front formulas are by the truss syndeton.
Further improvement of the utility model is: the derrick main body is divided into five sections, and every section trussed construction is identical, and each drag link, diagonal member are little flexibility depression bar.Connected by four bearing pins between each section, each junction also is provided with the attached plate of strengthening usefulness.
The herringbone hoisting rack that derrick rear and base rear are provided with is the device that derrick telescoping is used, couple together by the two-dimensional person cabinet frame of four bearing pins by cross bearer two monolithics, crossbeam adopts major diameter tubing, every side two connecting pins distance is big, simultaneously crossbeam center line and the cantilevered wheels dead in line that is contained on the herringbone hoisting rack, effectively balance the torsional moment that produces in the process that hoists.The man-like shelf foreleg is made up of two i iron, and leg centre position, front and back adds connecting rod and connects, the strut stability of leg before and after having improved.Cross bearer is provided with the third wheel of belt length axle, is used for changing the direction of winch drum to the wire rope of overhead traveling crane.Derrick hoists and finishes, and is locked by U-bolt and derrick body, and man-like shelf just constitutes derrick hypomere ingredient.
Further improvement of the utility model is: the shaped steel size of the bottom joint of the king-tower post of boring tower is greater than the shaped steel size of other joint, thereby the center of gravity of whole derrick is reduced, and strengthens resistance to overturning.
3.6 ° of whole rig front gradients, 0.8 ° of the unidirectional gradient in side, the derrick rigidity of section is nonlinear change, makes whole derrick when satisfying applying working condition to greatest extent, have enough intensity and stability, and it is minimum that material consumption is reduced to.
Further improvement of the utility model is: the boring tower rope sheave that hoists adopts shift sleeve structure.
Further improvement of the utility model is: base branch foreground and backstage two parts are carriers of whole rig and derrick; The foreground comprises several parts such as foreground base, thribble platform, table beam, winch beam, end straining beam, basis for the rig equipment, thribble beam, table beam, winch beam are the heavy in section welding I beam, be connected with the left and right sides base on foreground by upper and lower twice bearing pin respectively, its underpart connects whole foreground by several end straining beams as a whole, makes base have good steadiness when work; The backstage is the base of drilling rig power plant and transmission device thereof; AM/BAM is connected by eight bearing pins, and this structure makes rig have integral rigidity and stability preferably.When rig finishes displacement in boring, needn't just can carry out integral translation by derrick lowering.
The technological progress that the utility model is obtained is:
With four king-tower posts boring tower is made the structure that the cross section is the ∏ type, increased the working space in the boring tower, also increased the stability of boring tower; Whole boring tower is arranged to five sections trussed construction, easy disassembling, also convenient transportation.The epimere of boring tower is made the enclosure space frame construction that the four sides has truss to connect, and has strengthened resistance to overturning.Connection between each section of boring tower is to be connected the bearing pin connection with four by strengthening attached plate connection, and contact area connects increase greatly than the bearing pin of A type tower, thereby has improved the resistance to overturning and the supporting capacity of derrick.Four king-tower posts leave derrick plane section centre of form axle farthest, give full play to the effect of material.
For guaranteeing that derrick has big rigidity at place near the ground, on the first segment tower leg, adopt heavy one-level shaped steel, thereby the supporting capacity of whole derrick is improved.
Derrick hoists and uses man-like shelf both sides third wheel central axis and be connected the crossbeam central lines, has eliminated the bad moment of torsion that produces in the process that hoists.The whole pull-up of the derrick that derrick adopts equipment of itself to connect on ground or put down, it is convenient and reliable to rise and fall.
The boring tower rope sheave that hoists adopts the sliding sleeve form, improves dependability, reduces cost.
