Abstract
The utility model discloses a kind of adjustable clearance type sliding support meeting pipe stress requirement, comprise a U-shaped rigid support 1, described support 1 bottom side and two avris respectively Vertical direction are equipped with adjusting bolt 3, and limit adjusting bolt 3 described in each by adjusting nut 4 and be positioned at the length of U-shaped support; Between described U-shaped rigid support 1 liang of avris, guide rail and limit position part are provided with cross bar, described cross bar is also equipped with described adjusting bolt 3, and limits position by adjusting nut 4; Wherein, adjusting bolt 3 described in each is provided with positive stop 2 to the top inside described U-shaped support, and described limited location block 2 end face is provided with insulation spacer 5.The utility model effectively can improve adaptability during Pipe installing, improves the flexibility of pipeline, reduces pipeline stress, meets code requirement.
Description
Technical field
The present invention relates to the support of pipeline in boats and ships and ocean engineering, more particularly, relate to the adjustable clearance type sliding support meeting pipe stress requirement, be particularly useful for the excessive occasion that may cause pipeline damage of stress.
Background technique
In Naval Architecture and Ocean Engineering piping design, pipe holder normally adopts U-tube card sliding support and support bracket fastened form.U-tube card sliding support structure is simple, point sliding-type and fastening type, usually can restrained line 2 line degrees of freedom and 2 rotary freedoms, and fixed support can carry out the staff cultivation of 6 degrees of freedom to pipeline.Conventional stent pattern due to its structure simple, highly versatile, extensively adopts, but in the occasion of outbalance, often there is the situation not meeting usage requirement in piping design construction.The occasion that specification is high to high temperature difference, high pressure, large deformation and dangerous type has clear and definite Stress Check requirement.The large temperature difference pipeline of such as chemical-process pipeline, high pressure line, thin walled tube and LNG all needs strictly to check, and need select special support pattern, and requires to carry out relative set according to Stress calculation.
In common piping design, preferentially select conventional stent pattern, carry out Stress calculation according to specification and concrete condition; When Stress calculation not by time adjustable support arrange and pattern to reach final purpose.
Summary of the invention
The present invention is for meeting in Naval Architecture and Ocean Engineering for meeting a kind of adjustable clearance type sliding support meeting pipe stress and require that pipe stress calculation requirement designs.This support pattern effectively can improve adaptability during Pipe installing, improves the flexibility of pipeline, reduces pipeline stress, meets code requirement.
In order to achieve the above object, the invention provides a kind of adjustable clearance type sliding support meeting pipe stress requirement, comprise a U-shaped rigid support, described support bottom side and two avris respectively Vertical direction are equipped with adjusting bolt, and limit by adjusting nut the length that adjusting bolt described in each is positioned at U-shaped support; Between described U-shaped rigid support two avris, guide rail and limit position part are provided with cross bar, described cross bar is also vertically equipped with described adjusting bolt, and limits position by adjusting nut; Wherein, adjusting bolt described in each is provided with positive stop to the top inside described U-shaped support, and described limited location block end face is provided with insulation spacer.
The present invention meets the adjustable clearance type sliding support of pipe stress requirement, is made up of frame structure, positive stop, positioning stud and adjusting nut.Positioning stud is arranged in frame structure perforate, by changing the position of adjusting nut, comes the position of running fix stud and positive stop, and then the gap regulating the relative position of pipeline and regulate pipeline and support to retrain.Positioning stud is arranged in frame structure perforate.Frame structure perforate is circular hole or strip hole, holding down bolt can after Pipe installing trim locations.The size of adjustable clearance needs the result calculated in strict accordance with pipe stress to arrange, and meets pipe stress calculation requirement with the flexibility improving pipeline.After Pipe installing, adjusting nut needs fastening, ensures to install post gap size, stud and positive stop can not be made to produce any displacement, ensure system reliable operation.
The adjustable clearance type sliding support that the present invention meets pipe stress requirement is requirement according to pipe stress analysis result and carries out designing and ensure that pipeline can not reach the limit of rupture in various applying working condition, to ensure that pipe safety runs.The adjustable clearance type sliding support main structure that the present invention meets pipe stress requirement designs as secondary hull structural strength, and malformation is little, pipeline on four direction of displacement according to pipe stress result of calculation determination gap size.In the exigent situation of installation precision, can realize first coarse positioning install, after carry out the object of accurate adjustment, occasion special and important in boats and ships and ocean engineering can be met to meet the requirement of specification and use.
Accompanying drawing explanation
Fig. 1 is a kind of typical figure meeting the adjustable clearance type sliding support of pipe stress requirement.
Fig. 2 is the perspective view of adjustable clearance type sliding support of the present invention.
Embodiment
If Fig. 1,2 is typical figures that the present invention meets the adjustable clearance type sliding support of pipe stress requirement, support 1 can adopt various ways, structure will have sufficient intensity, guarantee can not cause deformation because pipeline is stressed, Main Function is fixed in hull structure by support entirety, adjusted relative position and the gap of bolt 3 and positive stop 2 and intermediate conduit by the position changing adjusting nut 4.Need between positive stop and pipeline according to use occasion, generally need insulation spacer 5 be set between positive stop and pipe surface, cause the danger of spark to prevent long-time wear-out failure pipeline and to prevent from rubbing.
The present invention meets the adjustable clearance type sliding support of pipe stress requirement, the requirement that need calculate in strict accordance with pipe stress, first determines the position of this support and meets the appropriate gap distance that stress requires.The frame structure of support is installed on hull structure according to design attitude and requires position, after Pipe installing is put in place, according to the position of the suitable accurate adjustment adjusting nut of designing requirement, the fixed stop of stud terminal and pipeline are kept gap (performing in strict accordance with pipe stress calculation requirement) accurately.Need after Pipe installing puts in place to carry out the test of system pound pressure and effect test, whether further check meets stress calculating results requirement, finally determines that support meets system usage requirement according to test result and result of calculation.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
