Abstract

The utility model discloses a large marine structure soft foundation weighing fulcrum displacement measurement device with high accuracy, comprising a plurality of jacks which are arranged below a large marine structure respectively. The plurality of jacks are installed on a plurality of weighing supports respectively; the jack is provided with a displacement sensor; the signal output end of the displacement sensor is connected with the signal input end of a data acquisition unit; and the data acquisition unit is connected with a computer. The device is characterized in that each weighing support is provided with a multi-point location horizontal altitude difference measurement device; the horizontal altitude difference measurement devices are connected with one another in series; and the horizontal altitude difference measurement device is communicated with the data acquisition unit. The device can measure and calculate the settlement quantity of each fulcrum of the large marine structure to obtain relatively accurate foundation settlement values of all the fulcrums of the large structure, and obtain the weight information of the structure through the further calculation of ta weighing system, thus playing a key role on selecting a subsequent lifting device.

Description

The soft basis of the large ocean works fulcrum displacement high precision measuring device of weighing
Technical field
The utility model relates to measurement mechanism, relates in particular to the soft basis of a kind of large ocean works fulcrum displacement high precision measuring device of weighing.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 structures such as supporting construction one 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 ocean works weighing system of measuring based on lifting jack is to utilize displacement transducer the displacement signal of each lifting jack to be changed into the electric signal of 4~20mA, and be that data transfer is given computing machine by the A/D data acquisition unit with analog-signal transitions, computing machine directly calculates the concrete weight of large ocean works according to formula.This measuring method is applicable to that slideway builds the place use of weighing.When to the large ocean works, particularly super, oversized marine structure is when subgrade is weighed, because lifting jack is weighed at soft basic upper support large ocean works and to it, the foundation condition deficiency of subgrade, sedimentation will certainly take place in ground.Therefore, when existing weighing measurement system carries out displacement measurement to the large ocean works on subgrade condition basis, can't obtain actual value, cause the weighing precision of weighing system to have certain error, bring certain difficulty for the selection of follow-up hanging apparatus; 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 the soft basis of a kind of large ocean works fulcrum displacement high precision measuring device of weighing, 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 system, 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 structure all can be obtained 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 basis of a kind of large ocean works fulcrum displacement high precision measuring device of weighing, comprise: place several lifting jack, several lifting jack below the large ocean works to be installed in respectively on several pad piers of weighing respectively, displacement transducer is installed on the lifting jack, the signal output part of displacement transducer links to each other with the signal input part of a data acquisition unit, and data acquisition unit links to each other with a computing machine; It is characterized in that: the pad pier position of respectively weighing is separately installed with a multiple spot position level height difference measurement mechanism, and contacts mutually between each level height difference measurement mechanism, and the level height difference measurement mechanism is connected with data acquisition unit.
Actual adjustable height=the L1+L2 of described each lifting jack, L1 are the data of corresponding displacement transducer, and L2 is the data of corresponding point vertical survey device.
Contact mutually by pipeline between described each level height difference measurement mechanism.
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 system, 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 structure all can be obtained the weight information of works comparatively exactly under the where basic situation in office.
