Abstract
The invention discloses a universal hinge type expansion joint. The universal hinge type expansion joint of the novel technical scheme comprises a corrugated pipe, a left connection pipe, a right connection pipe and a flow guide pipe, wherein hinge assemblies are arranged on the two sides of a barrel section formed by the corrugated pipe, and the left connection pipe and the right connection pipe; each hinge assembly comprises a crossed-shaped shaft, an end vertical plate, a side vertical plate, a hinge plate I, a hinge plate II, a hinge plate III and a reinforcing plate; the end vertical plates, the side vertical plates and the reinforcing plates are symmetrically fixed on the outer surfaces of the left connection pipe and the right connection pipe, and are fixedly connected; the hinge plates I, the hinge plates II and the hinge plates III are fixedly connected with the end vertical plates and the side vertical plates; the hinge plates I and the hinge plates II are located at the same end of the barrel section and gaps is formed between the hinge plates I and the hinge plates II; the hinge plates III are located at the other end of the barrel section and are arranged in the separated gaps of the hinge plates I and the hinge plates II; the hinge plates I, the hinge plates II and the hinge plates III are movably connected by the crossed-shaped shafts. The design of a universal ring in the universal hinge type expansion joint is omitted, and a designing and manufacturing process is simplified, so that the material cost and the manufacturing cost are greatly reduced.
Description
Technical field
The present invention relates to expansion joint application, particularly relate to a kind of Universal hinge expansion joint.
Background technique
Universal angle expansion joint is mainly used in the angular displacement of complicated pipeline or space piping; in this environment; many times be inconvenient to the supporting frame setting up the use of expansion joint needs; and the expansion joint self in work can produce internal pressure thrust, in order to the thin-walled flexible element reduced in supporting frame and protection expansion joint can use this element of cardo ring usually.But cardo ring not only increases the own load of expansion joint, and adds cost of production.
Summary of the invention
The object of this invention is to provide a kind of design brief, without the self-supporting Universal hinge expansion joint of cardo ring.
To achieve these goals, technological scheme of the present invention is achieved in that a kind of Universal hinge expansion joint, and it comprises bellows 2, is axially connected to the left adapter 1 at described bellows 2 two ends, right adapter 3, and the honeycomb duct 4 being fixedly installed on described bellows 2 inside, in described bellows 2 and described left adapter 1, the both sides of the shell ring that right adapter 3 is formed are provided with hinge component, and described hinge component comprises the cross spring 5, end riser 6, cant board 7, hinge plate I 8, hinge plate II 9, hinge plate III 10, stiffening plate 11, described end riser 6 symmetry is fixed on described left adapter 1, the outer surface of right adapter 3, described cant board 7 and described left adapter 1, the outer surface of right adapter 3 and the side of described end riser 6 are fixedly connected with, described stiffening plate 11 and described left adapter 1, outer surface and the described cant board 7 of right adapter 3 are fixedly connected with, described end riser 6, cant board 7, stiffening plate 11 is encircled a city a square tube, described hinge plate I 8, hinge plate II 9, hinge plate III 10 and described end riser 6, cant board 7 is fixedly connected with, described hinge plate I 8, hinge plate II 9 is positioned at same one end of described shell ring, and leaves gap therebetween, and described hinge plate III 10 is positioned at the other end of described shell ring, and is positioned at described hinge plate I 8, in the described gap at hinge plate II 9 interval, described hinge plate I 8, hinge plate II 9, the connecting end of hinge plate III 10 was flexibly connected by the described cross spring 5.
Further, the connecting end of described hinge plate I 8, hinge plate II 9, hinge plate III 10 is provided with the through hole matched with the described cross spring 5.
The present invention has following beneficial effect: the present invention not only has the angular displacement that can absorb in any plane, and the function of bellows pressure thrust can be born, and it omits the design of cardo ring in prior art Universal hinge expansion joint, simplify design, manufacturing process; Alleviate weight, greatly reduce cost of material and manufacture cost.
