Abstract
A pad pier with an adjustable height comprises a cylinder, a top tray, a lifting screw rod and a nut, wherein an upper ring plate and a lower ring plate are installed at the upper end and the lower end of the cylinder respectively, the lifting screw rod is installed on the lower portion of the top tray, the nut is installed on the lifting screw rod in a matching mode, the lifting screw rod stretches into a cavity of the cylinder, the nut is arranged on the upper ring plate of the cylinder, a rolling bearing is installed on the inner side of the bottom of the nut in a machining mode, several pairs of inner ring plates are installed on the two opposite sides of the inside of the cylinder, and the inner sides of the inner ring plates are embedded into the lifting screw rod through a pin key. Accordingly, the height of the pad pier can be adjusted according to the supporting height needed when a structural object is prefabricated, the pad pier is more convenient to use, and the problem that the height of an existing pad pier is unadjustable is solved; in addition, influences brought by field sedimentation on prefabrication of the structural object are eliminated, and construction quality is improved; meanwhile, construction difficulty is reduced and carrying capacity and production efficiency of the pad pier are improved.
Description
Technical field
The present invention relates to pad pier, relate in particular to a kind of for ocean platform jacket and the prefabricated process of chunk horizontal plate support, leveling support Height Adjustable pad pier, belong to Offshore Engineering field.
Background technology
Along with developing rapidly of ocean engineering, the exploitation dynamics of the oil platforms such as production platform, accommodation platform, central processing platform of building is constantly strengthened, and the build process of oil platform is had higher requirement.
Offshore oil platform is main comprising generally: the ocean engineering structures such as chunk, jacket, single-point.These works carry out marine installation work after has built on ground again.Along with being on the increase of platform construction project, in the prefabricated building course of ocean platform (as chunk, jacket etc.), need to use a large amount of pad piers.Pad pier not only can leveling support blocks and the single chip architecture of jacket, can also single chip architecture be grouping with welding process in play the effect of ballast, to prevent single chip architecture distortion.
Existing pad pier is generally cylindrical shell pad pier, by cylindrical shell and upper and lower ring flat-plate, formed, cylindrical shell is as support column, upper and lower ring flat-plate is respectively weldingly fixed on the upper and lower end of cylindrical shell, wherein, upper ring plate contacts with lacing wire or horizontal plate shaped steel, as the temporary supporting in the prefabricated process of ocean engineering structure (as chunk, jacket etc.).
Ocean engineering structure not of uniform size, varies in weight, and the height that need to support during construction is also different, and existing pad pier is stationary structure, because it is highly fixing, cannot carry out height adjusting.When reality is used, because pad pier height is fixed, the needs of reality in the time of can only be prefabricated according to works, change the pad pier of differing heights specification, thereby, cause construction more loaded down with trivial details, to site operation personnel, make troubles; Meanwhile, also can, because of the restriction of some prefabricated place bearing capacities, in the prefabricated process of works, can cause the local sedimentation on ground, bring adverse influence to the prefabricated work of works.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of Height Adjustable pad pier, needed bearing height when it not only can be prefabricated according to works, carry out the height of spacer pier, use conveniently, solve the problem that existing pad pier height can not highly regulate; And, also eliminated because place sedimentation is to the prefabricated impact bringing of works, improved construction quality; Meanwhile, reduce difficulty of construction, improved supporting capacity and the production efficiency of pad pier.
The object of the invention is to be realized by following technical scheme:
A kind of Height Adjustable pad pier, comprise: a cylindrical shell, the upper/lower terminal of cylindrical shell is respectively provided with a upper ring plate, lower ring plate, it is characterized in that: also comprise: a top pallet, be arranged on lifting screw below top pallet, coordinate the nut being arranged on lifting screw, wherein, lifting screw extend in the hollow of cylindrical shell; Nut is arranged on the upper ring plate of cylindrical shell, and the bottom inside cooperation of nut is provided with a rolling bearing; The both sides, inside of cylindrical shell are provided with several to inner ring plate relatively, and the inner side of inner ring plate is embedded in lifting screw by pin key.
The bottom of described top pallet is provided with reinforcement gusset.
The surrounding of described nut mutually correspondence is provided with dihedral handle.
Around described cylindrical shell and between lower ring plate, several bottoms are installed and strengthen gussets.
The inner side of described inner ring plate is embedded in after inner sleeve by pin key, then is embedded in lifting screw.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, needed bearing height when it not only can be prefabricated according to works, carrys out the height of spacer pier, uses conveniently, solves the problem that existing pad pier height can not highly regulate; And, also eliminated because place sedimentation is to the prefabricated impact bringing of works, improved construction quality; Meanwhile, reduce difficulty of construction, improved supporting capacity and the production efficiency of pad pier.

The specific embodiment
As shown in Fig. 1-4, the present invention includes: top pallet 1, adopt welding manner to be arranged on lifting screw 3 below of top pallet 1, by threaded engagement, to be arranged on the nut 4 on lifting screw 3, nut 4 is provided with a cylindrical shell 7 below, wherein, the bottom of top pallet 1 adopts welding manner that reinforcement gusset 2 is installed; The mutual correspondence of surrounding of round nut 4 also adopts welding manner that dihedral handle 5 is installed, and drives the rotation of round nut 4 by rotation dihedral handle 5; The upper/lower terminal of cylindrical shell 7 adopts welding manner that one upper ring plate 6, lower ring plate 9 are respectively installed, and lifting screw 3 extend in the hollow of cylindrical shell 7; The bottom inside cooperation of nut 4 is provided with a rolling bearing 10, and rolling bearing 10 plays lubrication to the rotation of round nut 4, to reduce frictional force.
Above-mentioned cylindrical shell 7 around and between lower ring plate 9, adopt welding manner that several bottoms are installed to strengthen gussets 8; It is several to inner ring plate 13 that the both sides, inside of cylindrical shell 7 adopt welding manner to be relatively provided with, and the inner side of inner ring plate 13 is embedded in inner sleeve 11 and lifting screw 3 by pin key 12; Wherein, the inner side of inner ring plate 13 is embedded in after inner sleeve 11 by pin key 12, then is embedded in lifting screw 3.Inner ring plate 13 plays the effect of strengthening structure resistance to compression and fixing inner sleeve 11, inner sleeve 11 to lifting screw 3 liftings play spacing effect, pin key 12 plays the effect that restriction lifting screw 3 rotates, and makes lifting screw 3 can only carry out oscilaltion activity.
During actual use, according to actual pad pier height needs, rotation dihedral handle 5, rotates nut 4, and spacing by screw thread transmission and pin key 12 can be risen or decline lifting screw 3, completes Height Adjustable function and demand.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
