Abstract

A weighing supporting structure of a marine structure comprises a plurality of jacks and box-shaped sliding shoes comprising box-shaped bodies with steel structures and woods arranged under the box-shaped bodies with the steel structures and are connected with the box-shaped bodies with the steel structures though bolts. The supporting structure is characterized in that the upper half parts of the box-shaped bodies with the steel structures in the box-shaped sliding shoes mutually and correspondingly expand and extend out of cross-shaped box-shaped bodies with steel structures towards two sides from the middle part, and the lower parts thereof are the I-shaped box-shaped bodies; and the jacks are uniformly distributed under the two wings of the cross-shaped box-shaped bodies expanding and extending. The utility model can be recycled on the premise of no effect on the precision of weighting results. Meanwhile, the utility model has the advantage of weighting preparation time greatly, reducing the repeated investment of manpower and material resources during the engineering constructing process; and improving the work efficiency.

Description

The braced structures of weighing of marine structure

Technical field

The utility model relates to the bracing or strutting arrangement of weighing, and relates in particular to a kind of braced structures of weighing that is used for marine structure.

Background technology

In the petroleum development engineering, need build various platforms such as production platform, accommodation platform, central processing platform at sea at sea.Platform general main comprising: ocean engineering chunk, ocean steel construction such as braced structures-jacket, single-point thing under water.Ocean engineering chunk, jacket, single-point etc. are commonly referred to as marine structure.After ocean engineering chunk, jacket construction are finished, need weigh to ocean engineering chunk, jacket.Final weight and the weight center that can measure works exactly by weighing, the work of weighing is for ocean engineering chunk, the such ocean steel construction thing of jacket, afloat installation has very important meaning, is the most important basic data of marine lifting operation.

As shown in Figure 1, be that existing marine structure 4---the braced structures of weighing of jacket comprises: box-shaped piston shoes 1, box-shaped piston shoes 1 are mainly by the box-like body 2 of steel work and be located at box-like body 2 and constitute with the wood 3 that the box-like body 2 of steel work is connected below by bolt.The marine structure 4 that need weigh---jacket places on the box-shaped piston shoes 1, is provided with on the conduit leg neighboring of jacket to install to be connected with two-layer ring flat-plate 5.Several jack 6 be placed between box-shaped piston shoes 1 and the ring flat-plate 5 and be looped around equably second layer ring flat-plate 5 below.When weighing, jack 6 is withstood on the upper ring plate 5.Because jack 5 is a hydraulic pressure, the oil circuit oil pressure that each jack 5 links to each other has reflected the stressed of jack, after jacket jack-up, the oil pressure data that are looped around each jack 6 below the ring flat-plate 5 are that the signal of telecommunication is sent to computer by cable by sensor with the oil pressure transformation of data.Computer calculates weight and the weight center that is claimed marine structure by the stress data of each jack 6.

As shown in Figure 2, be existing marine structure 4---the braced structures of weighing of ocean engineering chunk, comprise: the marine structure 4 that need weigh---ocean engineering chunk places on the box-shaped piston shoes 1, installation is set on the neighboring on the ocean engineering chunk column is connected with four layers of ring flat-plate 5, several jack 6 are equably around being placed on position between each two-layer ring flat-plate 5 up and down.When weighing, jack 6 is withstood on the second layer ring flat-plate 5, after engineering chunk jack-up, the oil pressure data that are looped around each jack 6 below the ring flat-plate 5 are that the signal of telecommunication is sent to computer by cable by sensor with the oil pressure transformation of data.Computer calculates weight and the weight center that is claimed marine structure by the stress data of each jack 6.

The braced structures of weighing of existing this marine structure will be at the weigh design of braced structures of design feature in design stage of ocean engineering chunk, jacket.Then, two-layer or four layers of ring flat-plate are installed on ocean engineering chunk, jacket periphery.And, also to process design, blanking, prefabricated, group to operations such as, welding.Weigh after the end, the whole braced structures of weighing just becomes scrap iron.Therefore, the existing this marine structure braced structures of weighing can only disposablely be used, and can not reuse, and whenever carries out the construction that an engineering all needs to carry out repetition.Great amount of manpower and material resources have been wasted, inefficiency.

The utility model content

Main purpose of the present utility model is to overcome the above-mentioned shortcoming that existing product exists, and a kind of braced structures of weighing of improved marine structure is provided, and it can reuse under the prerequisite that does not influence the weighing results precision.Simultaneously, shorten the time of weighing greatly, reduced the overlapping investment of man power and material in the engineering-built process.

The purpose of this utility model is realized by following technical scheme.

A kind of braced structures of weighing of marine structure, comprise: several jack with by the box-like body of steel work and be located at the box-shaped piston shoes that wood that the box-like body of steel work is connected with the box-like body of steel work below by bolt constitutes, it is characterized in that: the first half of the box-like body of the steel work in the box-shaped piston shoes from the middle part mutually corresponding to both sides expansion extend the box-like body that becomes to be criss-cross steel work, the latter half is the box-like body that is in-line, several jack be evenly distributed in the expansion extended criss-cross box-like body both wings below.

The beneficial effects of the utility model, the utility model is owing to adopt said structure, and it can reuse under the prerequisite that does not influence the weighing results precision.And need be at marine structure---on ocean engineering chunk, the jacket periphery ring flat-plate is installed.Simultaneously, shorten the time of weighing greatly, reduced the overlapping investment of man power and material in the engineering-built process, improved operating efficiency.

Below in conjunction with the drawings and the specific embodiments the utility model is described in detail.
