Abstract
The utility model discloses a device for measuring pivot subsidence of a soft foundation of a large-size ocean structure, which comprises a plurality of hydraulic jacks arranged below the large-size ocean structure, the plurality of hydraulic jacks are respectively arranged on a plurality of support blocks, the plurality of support blocks are respectively arranged on a foundation and are provided with communicators, a plurality of altitude difference sensors are respectively arranged on the communicators and are respectively connected with a data collector, and the data collector is connected with a computer. The device for measuring the pivot subsidence is used for measuring and calculating the subsidence of all pivots of the large-size ocean structure to obtain the relatively accurate foundation subsidence values of all the pivots of the large-size structure and further obtain the information of weight of the structure through calculation by a weighing and measuring device, thus playing a key role in selection of a follow-up lifting device. Simultaneously, the device for measuring the pivot subsidence can change the special requirement on the foundation in weighing of the large-size ocean structure, and can adapt to various working conditions to weigh the large-size ocean structure, especially super-large or ultra-large structures.
Description
Technical field
The utility model relates to measurement mechanism, relate in particular to a kind of adaptation on soft basis, by each fulcrum settling amount of large ocean works is measured calculating, obtain the comparatively accurately soft basic fulcrum settlement measuring device of large ocean works of ground sedimentation value of each fulcrum of large structure.Belong to marine oil engineering field.
Background technology
In the petroleum development engineering, need build various platforms such as production vessel, accommodation platform, central processing platform at sea at sea.Platform general main comprising: oceanographic engineering chunk, marine structure such as supporting construction-jacket, single-point under water.Oceanographic engineering chunk, jacket, single-point etc. are commonly referred to as marine structure.After oceanographic engineering chunk, jacket construction are finished, need weigh to oceanographic engineering chunk, jacket.Final weight and the weight center that can measure works exactly by weighing, the work of weighing is for oceanographic engineering chunk, the such marine structure of jacket, afloat installation has very important meaning, is the most important basic data of marine lifting operation.
At present, the large structure weighing system mainly is the to-and-fro movement that utilizes hydraulic jack, realization is to jacking, the support of works and the control that descends, and utilize displacement transducer to detect the top lifting height of each spud leg, detect the load situation of each lifting jack by pressure transducer, and adopt the solenoid control hydraulic jack to realize the whole-process automatic control of weighing process.
But most marine structures are to be placed on the on-the-spot slideway of weighing to weigh.Because each fulcrum of marine structure all is in the locations of structures that metal is built, the settling amount of generation is minimum can ignore; But if to marine structure, particularly super, oversized marine structure, when weighing, be again on subgrade condition basis, to carry out, because its foundation condition deficiency, each position of the fulcrum of these large ocean works all has certain settling amount, therefore, existing weighing measurement device has certain error when on subgrade condition basis the large ocean works being carried out weighing operation, and causes obtaining the accurate weight of large ocean works; Selection for follow-up hanging apparatus has brought certain difficulty; And to weighing of large ocean works, ground there is specific (special) requirements, can not satisfies the large ocean works high-precision weighing needs under the multiple complex situations.
The utility model content
Fundamental purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of large ocean works soft basic fulcrum settlement measuring device, it can be by measuring calculating to each fulcrum settling amount of large ocean works, obtain comparatively accurately ground sedimentation value of each fulcrum of large structure, and obtain the weight information of works by the further calculating of weighing measurement device, for having played key effect for the selection of follow-up hanging apparatus thereafter; Simultaneously, can adapt under the various operating modes weighing operation to the large ocean works, particularly super, super-huge works all can obtain the weight information of works comparatively exactly under the where basic situation in office.
The purpose of this utility model is realized by following technical scheme:
The soft basic fulcrum settlement measuring device of a kind of large ocean works, it is characterized in that: comprise that several place the hydraulic jack below the large ocean works respectively, several hydraulic jack place respectively on several pad piers, several pad piers place on the ground respectively, on the pad pier linker is installed, several high gap sensors be installed in respectively linker on, several high gap sensors link to each other with data acquisition unit respectively, data acquisition unit links to each other with computing machine.
Described data acquisition unit will be transferred to computing machine by communication network after will carrying out D/A switch from the signal that high gap sensor reads and stores.
Described pad pier is provided with pregroove marks, and linker is positioned in the pregroove marks of pad pier.
The beneficial effects of the utility model: the utility model is owing to adopt technique scheme, it can be by measuring calculating to each fulcrum settling amount of large ocean works, obtain comparatively accurately ground sedimentation value of each fulcrum of large structure, and obtain the weight information of works by the further calculating of weighing measurement device, for having played key effect for the selection of follow-up hanging apparatus thereafter.Simultaneously, can change the large ocean works is weighed to the specific (special) requirements of ground, can adapt under the various operating modes weighing operation to the large ocean works, particularly super, super-huge works, all can obtain the weight information of works under the where basic situation in office comparatively exactly, for selecting hoisting device thereafter, joining aspects such as button and played key effect.

Major label description in figure:
The 1-lifting jack, 2-pad pier, the high gap sensor of 3-, 4-linker, 5-works, 6-data acquisition unit, 7-computing machine, 8-ground.
Embodiment
As Fig. 1, shown in Figure 2, the utility model mainly comprises: several place hydraulic jack 1, several pad piers 2, several high gap sensors 3, linker 4, data acquisition unit 6 and computing machine 7 below the large ocean works 5 respectively, several hydraulic jack 1 place respectively on several pad piers 2, several pad piers 2 place respectively on the ground 8, and pad pier 2 is provided with pregroove marks; The base of several high gap sensors 3 be installed in respectively carry out linker 4 that settling amount measures above, linker 4 is positioned in the pad pier 2 corresponding pregroove marks stably, several high gap sensors 3 link to each other with data acquisition unit 6 respectively, and data acquisition unit 6 links to each other with computing machine 7.
Principle of work: when on marine structure 5 places the ground 8 on soft basis, weighing, because different sedimentations takes place in each position of the fulcrum ground, utilize linker 4 to carry out the accurate measurement of settling amount, obtain discrepancy in elevation information by high gap sensor 3, after the signal that the signal cable of the output terminal of high gap sensor 3 links to each other with the signal input part of a data collector 6, data acquisition unit 6 reads and stores from high gap sensor 3 carries out D/A switch, be transferred to one by communication network and carry out the computing machine 7 that calculates.
