Abstract
The invention discloses an easy-to-lift fiber expansion joint with a ring belt protection device. The fiber expansion joint comprises a ring belt, a heat-preservation layer, a trim strip, an upper connecting pipe, a lower connecting pipe, an upper annular plate, a lower annular plate, a pull rod, lifting plates and the ring belt protection device, wherein one sides of the lifting plates are welded on the pull rod, and the other sides of the lifting plates are welded on the upper connecting pipe; through holes are formed in the lifting plates; and the ring belt protection device is fixed on the surface of the ring belt through the trim strip. A layer of metal gauze is fixedly arranged outside the ring belt of the fiber expansion joint to protect the ring belt of the fiber expansion joint which can be protected in lifting and transportation processes and enable the ring belt to be difficultly abraded, so that the service life of the ring belt of the fiber expansion joint is prolonged. Moreover, lifting hooks are symmetrically arranged on a metal bracket to facilitate the start shipment in transportation, and also have the functions of reinforcing ribs, so that the expansion joint is difficultly damaged in the transportation.
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.Expansion joint is because volume ratio is bigger, and weight is heavier, and lifting is also relatively more difficult 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 filament expansion joint of easy lifting of zone circle band protective gear is provided.
For solving the problems of the technologies described above, the technological scheme that the present invention adopted is: a kind of filament expansion joint of easy lifting of zone circle band protective gear 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 astragal both sides are fixed on upper ring plate and the lower ring plate by press strip respectively, are thermal insulation layer between upper connecting tube, lower linking tube, upper ring plate, lower ring plate and the astragal, also comprise boatswain chair and astragal protective gear; One side of boatswain chair is welded on the pull bar; Another side is welded on the upper connecting tube, establishes through hole in the said boatswain chair, and the astragal protective gear is fixed on the astragal surface by press strip.
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.
As the further improved technological scheme of the present invention, 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 present invention, the thickness of boatswain chair 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.
The present invention installs the layer of metal net in the fixed outside of filament expansion pitch circle band; Can in the process of lifting and transportation, protect filament expansion pitch circle band, make it be difficult for being worn, thereby prolong the working life of filament expansion pitch circle band; And symmetry is equipped with suspension hook on Steel Support; Start shipment during transportation conveniently, suspension hook can also play the effect of stiffening rib, is not easy to damage expansion joint during transportation.
