Abstract
Opfindelsen består af en tætningsanordning for udstøbte koncentriske og cirkulærcylindriske rørsamlinger (l) og (2) f.eks. til brug for offshore konstruktioner. Systemet udgøres af et antal kompressionsblokke i elastisk materiale (3), som placeret side ved side danner et ringlegeme omkring det inderste rør (l). Kompressionsblokkene (3) er beliggende mellem fastsiddende føringsplader ( 4) og (5) og har slidser (9), som sammen med fastsiddende udstøbningsrør (6) danner styr for kompressionsblokkene (3). For aktivering af tætningsanordningen anvendes en mekanisk spændebåndsanordning (7). Ved radial fremføring afkompressionsblokkene (3) opnås forbedret forsegling og mekanisk fastholdelse af det udstøbte koncentriske hulrum (8).The invention consists of a sealing device for molded concentric and circular cylindrical pipe joints (1) and (2) e.g. for use in offshore constructions. The system is constituted by a plurality of compression blocks in elastic material (3) which, placed side by side, form an annular body around the inner tube (1). The compression blocks (3) are located between fixed guide plates (4) and (5) and have slots (9) which together with fixed casting pipes (6) guide the compression blocks (3). A mechanical clamping device (7) is used to activate the sealing device. By radially advancing the decompression blocks (3), improved sealing and mechanical retention of the cast concentric cavity (8) is achieved.
Description
Benævnelse Tætningsanordning for udstøbt koncentrisk rørsamling.Name Sealing device for cast concentric pipe assembly.
Opfindelsens AnvendelsesområdeField of application of the invention
Opfindelsen anvendes i forbindelse med udstøbte cirkulærcylindriske koncentriske rørsamlinger, for at tilvejebringe en effektiv forsegling af hulrummet og en fastholdelse af udstøbningsmaterialet med stor mekanisk styrke. Typisk anvendelse er i forbindelse med samlinger på offshore konstruktioner over eller under vand, som f.eks. enkeltpælsfundamenter og cylindriske skaftforbindelser for vindturbiner eller olie og gas platforme.The invention is used in conjunction with molded circular cylindrical concentric pipe joints to provide effective sealing of the cavity and retention of the high mechanical strength casting material. Typical applications are in connection with offshore structures above or below water, such as the single-pile foundations and cylindrical shaft connections for wind turbines or oil and gas platforms.
Standpunkt I kendte forseglingssystemer tilvejebringes tætning typisk ved en cirkulær forseglingsring i ét stykke, hvis virkning udelukkende afhænger af elasticiteten af det anvendte tætnings materiale. Kendte samlingstyper har lav mekanisk styrke og relativ kort levetid.In prior art sealing systems, sealing is typically provided by a one-piece circular sealing ring whose effect depends solely on the elasticity of the sealing material used. Known types have low mechanical strength and relatively short life.
Ved opfindelsen anvendes et antal kompressionsblokke i elastisk materiale, som ved mekanisk aktivering danner et ringlegeme. Herved tilvejebringes et tætningssystem, som har effektiv forsegling og fastholdelse af udstøbningsmaterialet. Samlingen er karakteriseret ved stor mekanisk styrke og lang levetidIn the invention, a number of compression blocks are used in elastic material which, by mechanical actuation, form an annular body. This provides a sealing system which has effective sealing and retention of the casting material. The assembly is characterized by great mechanical strength and long service life
Opfindelsen adskiller sig ffa kendte teknikker, som beskrevet i EP 1 637 788 A2 på følgende måde: a) Der anvendes 2 faste føringsplader beliggende vinkelret på rørsamlingens hovedakse b) Der anvendes fremføringsstyr i form af fastsiddende udstøbnings rør c) Forseglingsringen er opdelt i et antal kompréssionsblokke, som placeret side ved side tilsammen danner et forseglingsringlegeme, som aktiveres ved mekanisk fremføring i radiale retninger.The invention differs from known techniques as described in EP 1 637 788 A2 as follows: a) Two fixed guide plates perpendicular to the main axis of the pipe assembly are used b) Feed guide in the form of fixed casting pipes c) The sealing ring is divided into a number of compression blocks, which are placed side by side together form a sealing ring body which is activated by mechanical advance in radial directions.
Ved Opfindelsen opnås:The invention provides:
Forbedret forsegling og mekanisk fastholdelse af udstøbt materiale i et hulrum mellem to cirkulærcylindriske og koncentriske rør.Improved sealing and mechanical retention of cast material in a cavity between two circular cylindrical and concentric tubes.
Midlermeans
Kompressionsblokke af 2 forskellige typer i elastisk materiale og forsynet med slidser, 2 plane fastsiddende føringsplader beliggende vinkelret på rørsamlingens hovedakse henholdsvis over og under kompressionsblokkene, samt ffemføringsstyr som udgøres af fastsiddende udstøbningsrør. Desuden anvendes en radial spændebåndsanordning.Compression blocks of 2 different types in elastic material and provided with slots, 2 flat fixed guide plates perpendicular to the main axis of the pipe assembly respectively above and below the compression blocks, and five guide guide constituted by fixed casting pipes. In addition, a radial clamping device is used.
VirkemådeFunction
Kompressionsblokkene er placeret side ved side, så de tilsammen danner et ringlegeme omkring det inderste koncentriske rør. Kompressionsblokkene er beliggende mellem de 2 fastsiddende plane føringsplader. Forsegling og mekanisk styrke af samlingen tilvejebringes ved radial føring af kompressionsblokkene som aktiveres af en omkringliggende spændebåndsanordning. Hver blok aktiveres til fremføring retlinet mod centrum for samlingen. Dette foregår styret af de 2 fastsiddende plane føringsplader og af slidser i blokkene samt af den lodrette del af de fastsiddende udstøbningsrør.The compression blocks are placed side by side so that they together form an annular body around the inner concentric tube. The compression blocks are located between the 2 fixed flat guide plates. Sealing and mechanical strength of the joint are provided by radially guiding the compression blocks which are actuated by a surrounding clamping device. Each block is activated to advance straight to the center of the assembly. This is controlled by the 2 fixed flat guide plates and by slots in the blocks as well as by the vertical part of the stuck casting pipes.
