The invention discloses an easily suspended ring protection fiber expansion joint with a layering, comprising a ring, a thermal insulating layer, the layering, an upper connection pipe, a lower connection pipe, an upper annular plate, a lower annular plate and a pull rod, and further comprising a suspending plate and a ring protector, wherein one side of the suspending plate is welded on the pull rod, the other side of the suspending plate is welded on the upper connection pipe, and the suspending plate is internally provided with a through hole; the ring protector is fixed on the surface of the ring through the layering; and the fixing hole is perforated in a mechanical perforation manner. According to the easily suspended ring protection fiber expansion joint with the layering, disclosed by the invention, the fixing hole is perforated in the layering through a mechanical perforation method so that the production efficiency can be improved; and the mounting efficiency can be improved due to an oblong fixing hole, and the suspending plate is symmetrically arranged on the pull rod, thus the easily suspended ring protection fiber expansion joint is convenient to convey during conveyance, and is not easy to break a compensator during the conveyance; and a metal net is additionally arranged outside the ring, and the ring is prevented from being worn, thus the service life of a fiber expansion joint ring is prolonged.
Description
Technical field
The present invention 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.Because filament expansion pitch circle band is generally made with rubber material, easy abrasion under the situation of repeatedly lifting transportation reduces its working life.Press strip is used for astragal is fixed on the thermal insulation layer outside.Traditional press strip punching is to adopt the manpower punching, bothersome effort, inefficiency.And expansion joint lifts relatively difficulty because volume ratio is bigger, and weight is heavier during transportation.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to above-mentioned existing technology, and a kind of astragal protection filament expansion joint of the easy lifting with press strip is provided.
For solving the problems of the technologies described above, the technological scheme that the present invention adopted is: a kind of astragal protection filament expansion joint of the easy lifting with 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; It is characterized in that: also comprise boatswain chair and astragal protective gear; 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; The astragal protective gear is fixed on the astragal surface by press strip; Said fixed hole is got for the mode that adopts mechanical punching.
As the further improved technological scheme of the present invention, said fixed hole be shaped as oblong.
As the further improved technological scheme of the present invention, the span between the said fixed hole is 5-10 centimetre.
As the further improved technological scheme of the present invention, the span between the said fixed hole is 8 centimetres.
As the further improved technological scheme of the present invention, every limit symmetry is equipped with 2 boatswain chairs on two of said pull bar relative frames.
As the further improved technological scheme of the present invention, the thickness of suspension hook is 0.5-2 centimetre.
As the further improved technological scheme of the present invention, the diameter of through hole is 2.5-7 centimetre.
As the further improved technological scheme of the present invention, said astragal protective gear is wire netting or sheet metal.
As the further improved technological scheme of the present invention, said astragal protective gear is a wire netting.
As the further improved technological scheme of the present invention, said astragal protective gear is a steel wire.
The present invention gets fixed hole with the method for mechanical punching on press strip, can practice thrift manpower greatly, enhances productivity; Oblong fixed hole can 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; Start shipment during transportation conveniently, boatswain chair can also play the effect of stiffening rib, is not easy to damage compensator during transportation; Fixed outside at filament expansion pitch circle band is installed the layer of metal net, can in the process of lifting and transportation, protect filament expansion pitch circle band, makes it be difficult for being worn, thereby prolongs the working life of filament expansion pitch circle band.
