Description
Technical Field
The utility model relates to a install showy rubber tube between two sections steel pipes, specifically speaking are showy rubber tube that both ends and steel pipe are connected.
Background
Some offshore conveying pipelines matched with the dredging construction ship take steel pipes as main bodies. To reduce vibration and improve pipeline flexibility, a rubber hose is often installed between two sections of steel pipe. When the steel pipe works, the steel pipe can float on the water surface only by being supported by buoys or floating rings and the like. The rubber tube connected with the steel tube is under the action of vertical downward gravity on one hand and under the action of horizontal stretching of the steel tubes at two ends on the other hand. The two work together to make the hose slender and easy to bend excessively. The rubber tube is excessively bent, so that local vortex is easily formed in the tube cavity, and the abrasion of the rubber material of the inner lining layer is accelerated; the rubber tube becomes slender, and the rubber material of the inner liner becomes thin. Therefore, the lining layer is easy to wear through, and the service life of the rubber pipe is influenced.
Disclosure of Invention
For overcoming the not enough of prior art existence, the utility model aims to provide a showy rubber tube that both ends and steel pipe are connected can avoid the rubber tube to sink, reduces the tensile force of both ends rubber tube.
The utility model discloses a realize through following technical scheme.
The utility model provides a both ends and steel pipe connection's showy rubber tube, includes the hose body and locates the steel flange at hose body both ends, its characterized in that: the hose body is in a dumbbell shape with two thick ends and a thin middle part; the thick sections at the two ends are sequentially provided with an inner liner layer, a reinforcing layer, a middle adhesive layer, a foam material layer and an outer coating layer from inside to outside; the middle thin section is sequentially provided with an inner liner layer, a reinforcing layer, a middle adhesive layer and an outer coating layer from inside to outside.
Further, the lining layer rubber material extends to the lower edge of a screw hole on the outer surface of the flange to form flange face sealing rubber. The flange contains the connecting piece, has welded the fixed steel loop on the connecting piece to tie up the steel wire and fix the enhancement layer cord fabric. 4 lifting lugs are welded on the inner side of the floating rubber pipe flange and are uniformly arranged at 90 degrees, and two ends of the lifting lugs correspond to each other.
Further, the total length of the floating rubber tube is 5-6m, wherein the length of the middle thin section is 0.8-1 m.
The utility model has the advantages that: the floating rubber pipe overcomes the gravity of the floating rubber pipe with the buoyancy of the floating rubber pipe, the working state of the floating rubber pipe cannot sink, the floating rubber pipe is less influenced by the tensile force of the steel pipes at two ends, the phenomena that the rubber pipe is excessively bent and the rubber material of the inner liner becomes thinner due to the stretching cannot be generated, and therefore the service life of the floating rubber pipe is longer.
Drawings
Fig. 1 is an appearance schematic diagram of the present invention.
Fig. 2 is a schematic structural view of a section a-a in fig. 1.
The labels in the figure are: the flexible pipe comprises a hose body 1, a flange 2, a pipe body left side thick end 11, a pipe body right side thick end 12, a middle thin section 13, an inner liner layer 3, an enhancement layer 4, a middle glue layer 5, a foam material layer 6, an outer coating layer 7, a bundling steel wire 8, a lifting lug 9, flange face sealing rubber 10, a connecting piece 21 and a fixing steel ring 22.
Detailed Description
The utility model provides a two ends and steel pipe connected's showy rubber tube, includes hose body 1 and locates the steel flange 2 at hose body 1 both ends, and the hose body is the both ends thick, the thin dumbbell shape in middle part. The floating rubber hose comprises a left thick end 11 of the hose body, a right thick end 12 of the hose body and a middle thin section 13, and the floating rubber hose has certain flexibility as a whole.
The thick section of the hose body is sequentially provided with an inner liner layer 3, a reinforcing layer 4, a middle adhesive layer 5, a foam material layer 6 and an outer coating layer 7 from inside to outside; the middle thin section is sequentially provided with an inner liner layer, a reinforcing layer, a middle adhesive layer and an outer coating layer from inside to outside. The thin section is free of the foam layer 6. Therefore, the floating rubber pipe can float in the working state, cannot sink under the action of gravity, and is less subjected to the tensile force of the steel pipes at two ends.
The lining layer rubber material 3 extends to the lower edge of a screw hole on the outer surface of the flange 2 to form flange face sealing rubber 10, so that the flange face is in a sealing state after the rubber pipe is connected with the steel pipe. The semi-sealed structure saves materials and avoids the situation that the rubber material is easy to be damaged by machinery because the rubber material possibly exceeds the flange plate when being pressed. The flange comprises a connecting piece 21, and a fixing steel ring 22 is welded on the connecting piece to fix the reinforcing layer cord fabric 4 by the binding steel wire 8. 4 lifting lugs 9 are welded on the inner side of the flange and are uniformly arranged at 90 degrees, and the two ends of the flange are symmetrical, so that the flange is convenient to lift.
The total length of the floating rubber pipe is 5-6m, wherein the length of the middle section 13 is 0.8-1 m.
The rubber tube partially floats out of the water surface in the working state; the thin section does not contain a foam material layer, so that the rubber tube has better flexibility. The lining layer rubber material extends to the lower edge of the screw hole of the flange surface, so that the flange surface is in a sealing state after the rubber pipe is connected with the steel pipe.
The utility model discloses overcome the gravity of self with the buoyancy of self, operating condition can not sink, receives the tensile force influence of both ends steel pipe less, can not produce the phenomenon of the excessive bending of rubber tube and inner liner sizing material attenuation because of the drawing, therefore has longer life.
