Abstract
The utility model discloses a fiber expansion joint provided with a ring belt protecting device and easy to hoist. The fiber expansion joint comprises a ring belt, a heat insulation layer, a pressing strip, an upper joint pipe, a lower joint pipe, an upper ring plate, a lower ring plate, a pull rod, a hoisting plate and the ring belt protecting device, wherein one edge of the hoisting plate is welded on the pull rod, the other edge of the hosting plate is welded on the upper joint pipe, a through hole is formed in the hoisting plate, and the ring belt protecting device is fixed on the surface of the ring belt by the pressing strip. According to the fiber expansion joint provided with the ring belt protecting device and easy to hoist, a layer of metal mesh is fixedly installed outside the fiber expansion joint ring belt, so that the ring belt of the fiber expansion joint can be protected in hoisting and conveying processes and can not be abraded easily, therefore, the service life of the ring belt of the fiber expansion joint is prolonged; and hooks are symmetrically arranged on a metal bracket, so that the lifting of the expansion joint is convenient during conveying, and furthermore, the hooks play the role of reinforcing ribs, so that the expansion joint can be not be damaged easily in the conveying 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.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.
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 easy lifting of zone circle band protective gear 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 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 utility model, said astragal protective gear is wire netting or sheet metal.
As the further improved technological scheme of the utility model, said astragal protective gear is a wire netting.
As the further improved technological scheme of the utility model, said astragal protective gear is a steel wire.
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 is installed 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.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
Embodiment
Embodiment 1
Referring to Fig. 1, the filament expansion of the easy lifting of this zone circle band protective gear joint 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, and astragal 1 both sides are fixed on upper ring plate 6 and the lower ring plate 7 by press strip 3 respectively, are thermal insulation layer between upper connecting tube 4, lower linking tube 5, upper ring plate 6, lower ring plate 7 and the astragal 1; 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, be not worn, thereby prolong its working life; 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.
