Abstract
The invention discloses an easy-to-lift totally-sealed fiber expansion joint with a ring belt protection device. A ring belt is wrapped outside a heat-preservation layer in a total sealing way. Lifting hooks are symmetrically arranged on a pull rod of the expansion joint. The ring belt protection device is fixedly arranged on the surface of the ring belt, and is a metal gauze or a metal plate. Compared with an open ring belt, the ring belt of the expansion joint has the advantages of well protecting the internal heat-preservation layer and prolonging the service life of the fiber expansion joint; lifting plates are symmetrically arranged on the pull rod of the expansion joint 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; and the metal gauze is arranged outside the ring belt, and can be used for protecting the ring belt from abrasion, so that the service life of the ring belt of the fiber expansion joint is prolonged.
Description
Technical field
The present invention relates to a kind of expansion joint, particularly a kind of non-metal expansion joint.
Background technique
The filament expansion joint can provide bigger multidirectional compensation rate on less axial mounting distance; Can effectively eliminate simultaneously the installation integrating error of whole system; So extensively adopted; 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.Traditional filament expansion pitch circle band is open type often, when the big pipeline of inleakage uses, can lower blast like this, but because seal, cause the corrosion of base insulating layer easily, the working life of reduction expansion joint; And expansion joint lifts relatively difficulty because volume ratio is bigger, and weight is heavier during transportation; Filament expansion pitch circle band is generally made with rubber material, and easy abrasion under the situation of repeatedly lifting transportation reduces its working life.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to above-mentioned existing technology, and a kind of all-sealed filament expansion joint of zone circle band protective gear of easy lifting is provided.
For solving the problems of the technologies described above; The technological scheme that the present invention adopted is: a kind of all-sealed filament expansion joint of zone circle band protective gear of easy lifting; Comprise 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; 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 respectively by the press strip sealing and fixing on upper ring plate and lower ring plate, be 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 being welded on the pull bar of boatswain chair, 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.
As the further improved technological scheme of the present invention, said astragal is that ethylene propylene diene rubber applies glass cloth.
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 0.6-2 centimetre.
As the further improved technological scheme of the present invention, the thickness of suspension hook is 1 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, the diameter of through hole is 3.5 centimetres.
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 all-sealed thermal insulation layer outside that is wrapped in of astragal of the all-sealed filament expansion joint of the zone circle band protective gear of easy lifting of the present invention; Be applicable to the pipeline that inleakage is little; Compare the open type astragal and have the thermal insulation layer that to protect inside; Make it avoid prolonging the working life of filament expansion joint from the chemical corrosion in outside and the pipeline; It is soft that the ethylene propylene diene rubber of selecting for use applies glass cloth performance, can absorb the displacement amount from each side.And symmetry is equipped with boatswain chair on the pull bar of expansion joint, start shipment during transportation conveniently, and boatswain chair can also play the effect of stiffening rib, is not easy to damage expansion joint 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.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
Embodiment
Embodiment 1
Referring to Fig. 1, this is the all-sealed filament expansion joint of the zone circle band protective gear of lifting easily, comprises astragal 1, thermal insulation layer 2, press strip 3, upper connecting tube 4, lower linking tube 5, upper ring plate 6, lower ring plate 7 and pull bar 8; Pull bar 8 is fixedly connected with upper connecting tube 4, lower linking tube 5 respectively through support, and upper ring plate 6 is connected with upper connecting tube 4 vertical fixing, and lower ring plate 7 is connected with lower linking tube 5 vertical fixing; The upper end of lower linking tube 5 is stretched in the upper connecting tube 4; Astragal 1 both sides respectively by press strip 3 sealing and fixing on upper ring plate 6 and lower ring plate 7, promptly press strip 3 is tightly connected with upper ring plate 6 and lower ring plate 7, connects mutually between upper connecting tube 4, lower linking tube 5, upper ring plate 6, lower ring plate 7 and the astragal 1; Cavity of middle formation; Be filled with filler in the cavity, this filling space is thermal insulation layer 2, and the material that astragal 1 is selected for use is that ethylene propylene diene rubber applies glass cloth; Every limit symmetry is equipped with 2 boatswain chairs 9 on two relative frames of pull bar 8,2 on every limit, and boatswain chair 1 is the steel plate of 1 cm thick for thickness; In establish through hole; Through-hole diameter is 3.5 centimetres, slings easily thereby can let the hook of lifting machine put in, and makes things convenient for entrucking, moves etc.Boatswain chair 9 is welded on the effect that can also play stiffening rib on the pull bar 8, makes expansion joint not fragile; In astragal 1 mounted on surface steel wire 10 is arranged, chain link fence 10 is rolled in astragal 1 outside, and the edge is fixed up by press strip 3, and astragal 1 is not directly contacted with the outside, when lifting and transportation, is not worn, thereby prolongs its working life; The astragal of sealed type is compared the open type astragal and is had the thermal insulation layer that can better protect inside, makes it avoid prolonging the working life of filament expansion joint from the chemical corrosion in outside and the pipeline.
