Abstract
The utility model discloses an easily-hoisted fiber expansion joint with a novel hold-down strip. The hold-down strip is provided with an oblong fixing hole; hoisting plates are symmetrically arranged on a draw rod; each hoisting plate is a metal plate having a certain thickness; and each hoisting plate is provided with a through hole. By using the oblong fixing hole instead of the traditional circular fixing hole which can only be fixed on one point, more fixing spaces can be selected in the mounting process, and the mounting efficiency is improved; the hoisting plates are symmetrically arranged on the draw rod, so that the fiber expansion joint can be conveniently hoisted in the transportation process; and the hoisting plates further have the effect of reinforcing ribs, thereby ensuring that a compensator can not be easily damaged in the transportation process.
Description
Technical field
The utility model relates to a kind of expansion joint, particularly a kind of filament expansion joint.
Background technique
Expansion joint is the additional stress that causes because of temperature difference and mechanical vibration in order to compensate, and is arranged on a kind of flexible structure on container shell or the pipeline.Because it is as a kind of elastic compensating element that can freely stretch, advantages such as reliable operation, functional, compact structure have been widely used in departments such as chemical industry, metallurgy, nuclear energy.The filament expansion joint can provide bigger multidirectional compensation rate on less axial mounting distance, can effectively eliminate the installation integrating error of whole system simultaneously, than traditional expansion of metal joint the better application prospect is arranged.Filament expansion pitch circle band covers outside the thermal insulation layer, and main effect is to bear flue gas system pressure and from flue gas and extraneous chemical corrosion, protect thermal insulation layer.Press strip is used for astragal is fixed on the thermal insulation layer outside.Press strip realizes through fixed hole that fixedly traditional press strip fixed hole is circular, and nail is aimed at the center of circle and could be fixed, and efficient is lower.And compensator lifts relatively difficulty because volume ratio is bigger, and weight is heavier during transportation.
The model utility content
The utility model technical problem to be solved is the deficiency to above-mentioned existing technology, and a kind of filament expansion joint of the easy lifting with press strip that can quick mounting is provided.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of filament expansion joint of the easy lifting with novel press strip comprises astragal, thermal insulation layer, press strip, upper connecting tube, lower linking tube, upper ring plate, lower ring plate and pull bar; Pull bar is fixedly connected with upper connecting tube, lower linking tube respectively through support, and upper ring plate is connected with the upper connecting tube vertical fixing, and lower ring plate is connected with the lower linking tube vertical fixing; The upper end of lower linking tube is stretched in the upper connecting tube; The fixed hole that some is arranged on the press strip, press strip is separately fixed at the astragal both sides on upper ring plate and the lower ring plate through fixed hole, is thermal insulation layer between upper connecting tube, lower linking tube, upper ring plate, lower ring plate and the astragal; Also comprise boatswain chair; One side of boatswain chair is welded on the pull bar, and another side is welded on the upper connecting tube, establishes through hole in the said boatswain chair; Said fixed hole be shaped as oblong.
As the further improved technological scheme of the utility model, the span between the said fixed hole is 5-10 centimetre.
As the further improved technological scheme of the utility model, the span between the said fixed hole is 8 centimetres.
As the further improved technological scheme of the utility model, every limit symmetry is equipped with 2 boatswain chairs on two relative frames of said pull bar.
As the further improved technological scheme of the utility model, the thickness of boatswain chair is 0.5-2 centimetre.
As the further improved technological scheme of the utility model, the diameter of through hole is 2.5-7 centimetre.
The utility model adopts oblong fixed hole let has more fixed space to select when installing; Rather than as traditional circular fixed hole, can only be fixed on a point; Can improve installation efficiency, and symmetry is equipped with boatswain chair on pull bar, starts shipment during transportation conveniently; Boatswain chair can also play the effect of stiffening rib, is not easy to damage compensator during transportation.
