Description
Technical field
The present invention relates to a kind of assembled truss framed leg device, relate in particular to a kind of truss framed leg device of self-elevating ocean platform.Belong to the ocean engineering mechanical field.
Background technology
Along with the development of Offshore Oil Industry, self-elevating ocean platform will develop to deep water sea area, and the ambient conditions that platform faces is also further harsh.As the important component part of self-elevating ocean platform, the important function that spud leg plays the support ocean platform and suffered environmental load is delivered to seabed by platform.Each self-elevating ocean platform has the spud leg more than 3 or 3 to support when ocean platform changes operating location, need be by the platform towage to another place.Before towage, first every spud leg is utilized to the device on platform, more than extracting sea bed and being raised to sea level, then be chosen under the good condition of environmental aspect and carry out towage.
At present, self-elevating ocean platform is all used the integral type spud leg, and single spud leg is as a whole, once built, just non-dismountable.This has the following disadvantages: (1), in the towage process, more than spud leg is lifted to sea level, is subject to the impact of environmental load very large, and moving of platform navigated and produced safely very large threat.(2) spud leg length and quality are very large, and operation inconvenience during the lifting spud leg is dangerous high.(3) once the design head of platform is definite, but the length of spud leg is also determined thereupon, for some operating modes, allows the darker marine site of the depth of water, and its job area just is restricted.
Look into Chinese patent, a kind of truss connecting device, number of patent application: 201220003017.9, this truss connecting device is mainly connected by the flange of arranging between truss, for the elevator installing area, due to three flange faces effectively contact simultaneously that can't guarantee on same truss, and lack corresponding bracing reinforcement parts, therefore can not guarantee the stability of truss, the residing marine environment complexity of truss framed leg in addition, the truss abutted flange is installing the also larger difficulty of existence, so this device fails to obtain practical application.Number of patent application and for example: 200610134682.0, be a kind of assembly method of large truss type pile leg structure.It mainly passes through moulding bed device, the welding manufacture of auxiliary girder formula spud leg, construction precision and the quality of assurance truss framed leg.But it can not solve the operation difficult problem of current deep water platform and the safety issue of platform towage.
Summary of the invention
The objective of the invention is the defect existed in order to overcome prior art, is an operation difficult problem that solves deep-sea platform, and providing a kind of can, according to the depth of water in operation marine site, facilitate, adjust reliably the assembled truss framed leg device of truss framed leg length.The present invention can also by the dismounting to truss framed leg, reduce the spud leg rising height before the platform towage, thereby improves the safety of jack-up unit towage.
In order to achieve the above object, the present invention is achieved by the following technical programs:
A kind of assembled truss framed leg device, comprise the truss framed leg that is connected with shoe, described truss framed leg comprises the chord member that becomes equilateral triangle to distribute by 3 vertical sections, and every chord member outer circumference surface is symmetrically connected with respectively 1 toothed rack vertically, and be respectively equipped with at least 2 isolation up and down on three facades along its length at chord member, and the triatic stay be connected with chord member forms; Described assembled truss framed leg device is at least two-layer, between truss framed leg and truss framed leg, is provided with to be connected the location joint for chord member; Described connection location joint by outer circumference surface vertically symmetry offer two grooves, and the vertical radial direction through hole that radially has at the groove width median plane with reference column, be sleeved on the reference column cylindrical and have two semi-circle tubular retaining sleeves of the radial direction through hole corresponding with reference column and the bolt pair that is placed in radial direction through hole forms; Two truss framed legs, its each corresponding chord member, under the acting in conjunction of positioned internal post and outside two semi-circle tubular retaining sleeves and bolt pair, is assembled into a complete truss framed leg.
Purpose of the present invention can also further realize by following technical measures.
Described connection location joint also comprises the elastic cushion block be sleeved on the retaining sleeve periphery, elastic cushion block and the contacted one side of retaining sleeve periphery are arc surface, the curvature of arc surface is identical with the radius of curvature of described radius retaining sleeve periphery, another side is plane, center offers a through hole, and open a breach on the limit, hole, and make it there is certain elastic deformation amount, lost efficacy in case bolt pair is loosening.
The tooth bar that described chord member is provided with tooth by 2 semi-circular tubes with 1 corresponding two sides is connected and forms, and between two joint faces of described 2 semi-circular tubes, embedding accompanies tooth bar, and the outer circumference surface of chord member is stretched out respectively on the two sides that tooth bar is provided with tooth; Tooth bar meshes for the gear with on platform, then by swing pinion lifting spud leg.
Described tooth bar stretches out the thickness that dedendum line that the length of the outer circumference surface of chord member is tooth bar is greater than described retaining sleeve; The thickness of described tooth bar is the width that is slightly smaller than or equals two grooves that described reference column is provided with; The length of described tooth bar and described chord member are isometric, and are the integral multiple of rack tooth distance; Every toothed rack disconnect position is identical with respect to the position of profile of tooth, and disconnect position is a whole tooth end position.
The upper and lower two ends of described tooth bar have a U-shaped breach along center line, and the degree of depth of U-shaped breach is be a bit larger tham or equal 1/2nd of reference column length, and the width of U-shaped breach is the radial spacing that is a bit larger tham or equals two grooves that reference column is provided with.
The diameter of described reference column is the internal diameter that is slightly less than or equals described chord member, and the upper and lower side of described reference column and groove notch are equipped with the chamfering of 30-45 ° of degree.
Also be connected with the hound of splayed or herringbone between described upper and lower triatic stay.Going back level connection joint among described triatic stay has the internal overarm support of △ shape.The cross sectional shape of described strut is circle.
Described shoe is connected with the lower end of the bottom truss framed leg of described assembled truss framed leg device.
The present invention is simple in structure, easy to use, safe and reliable.Under the prerequisite of the function that meets truss framed leg, by the truss framed leg of jack-up unit, by equitable subsection, convenient, science assembled, realized integrated truss framed leg is become to removable form.Can be dismantled spud leg in the towage process, thereby can be changed flexibly spud leg length, the safety that effectively improves towage operating mode lower platform.When the lifting spud leg, more convenient to operate, safety is higher.Simultaneously, in the situation that environmental load allows, can suitably increase the spud leg length of jack-up unit by this truss framed leg linkage, thereby increase the operating water depth of platform, improve the applicability of ocean platform.
