Abstract

The invention relates to a tensioner supporting frame which comprises an upper frame, a lower frame, fixing seats, a coupling bolt, a pressure sensor and a protection top. The supporting frame is mainly used for supporting and bearing pressure from a vertical direction, tension from a horizontal direction and overturning moment from side directions. The pressure sensor is mainly used for transmitting tension electrical signals, wherein one path of signal enters a display system to express an instantaneous tension value; and the other path of signal enters an automatic control system so that a tensioner performs automatic pipeline winding and unwinding operations in an automatic control mode. The weights of the tensioner and the pipelines are supported by four fixing seats, the fixing seats are special structure components like a pair of slippers, a layer of cylindrical roller is inlaid in the each slipper, the fixing seats are arranged on the bearing sliding flange of the lower frame and can move along the pipeline direction on the bearing sliding flange, and the freedom degrees of the fixing seats in other four directions are restricted. In the pipe paving operation process, the tension measuring accuracy and sensitivity are improved by using the tensioner supporting frame.

Description

A kind of stretcher bearing support

Technical field

The innovation of the present invention and a kind of ocean engineering field pipe laying barge pipelaying work bulking block.

Background technique

Offshore production oil gas mainly relies on submarine pipeline to carry; The effect that submarine pipeline is laid in the oil gas conveying is more and more important; Stretcher is as the visual plant of pipe laying barge pipelaying work; Its critical function is the clamping pipeline, and in the pipe laying process with the even retractable pipeline of certain speed.China is from introduction pipe laying barge in 1976, existing at present strand 106, strand 109, blue boundary number, triumph 901, offshore oil 101, offshore oil 201,202 etc.In the pipe laying barge pipelaying work; Pipeline is under the pipe laying barge stern during water; One section unsettled section than length is arranged, because sagging swinging gone up in the influence of pipe laying barge wind-engaging, wave, tide from the stern to the seabed; The distance of pipeline between from the stern to the seabed constantly changes, and this makes unsettled section length and pipeline stress also change thereupon.Flexural stress when reducing pipe laying, the pipeline that can make that uses stretcher to be provided with at pipe laying slideway place is in extended state, but stretcher is measured the precision and the sensitivity of tension force and under this working environment, often can't be reached requirement.

Summary of the invention

The technical problem that the present invention solves has provided a kind of stretcher bearing support, and its effect is to have guaranteed that stretcher is realized the work of automatic retractable pipeline under automatic control mode in the pipelaying work process.

The technical solution adopted for the present invention to solve the technical problems is, a kind of stretcher bearing support, comprise put on the shelf, undercarriage, fixed base, attachment bolt, pressure transducer and protection top.The main effect of bearing support is to support and carry, and bears the effect of tilting moment of tension force and the side direction of pressure from Vertical direction, substantially horizontal.Pressure transducer mainly is to be used for transmitting the tension force electrical signal, and wherein one road signal gets into display system, expresses instantaneous tension value; Another road signal gets into automatic control system, makes stretcher under automatic control mode, realizes the work of automatic retractable pipeline.The weight of stretcher and pipeline is pressed on four fixed bases, and fixed base is a special construction spare, and as a pair of piston shoes, pad one deck roller is through on the supporting slip flange of undercarriage in the boots.And can move along the direction of pipeline above that, and be limited in the degrees of freedom of other four directions.

The invention has the beneficial effects as follows, in the pipelaying work process, improved precision and the sensitivity of measuring tension force.
