Description

Technical Field

[0001] This utility model relates to a floating rubber hose for transporting mineral sand. Background Technology

[0002] Mineral sands extracted from the seabed or islands are often transported to shore via floating pipelines. Sometimes, pipeline damage is not due to wear and tear on the pipe walls from large particles during transport, but rather to excessive bending of the pipeline. This is especially true for pipelines composed of small-diameter rubber hoses; if the pipeline is long, when not in operation, it can experience significant bends, sometimes exceeding 360 degrees, when encountering large waves due to its low rigidity. If a pump is started to transport materials under these conditions, localized high pressure or localized eddies, or even both simultaneously, can easily occur, leading to a pipe burst. Summary of the Invention

[0003] To overcome the above shortcomings, the purpose of this utility model is to provide a floating hose for transporting ore. This hose has good rigidity and will not cause abnormal bursting or wear due to excessive deformation of the lumen, thus having a long service life.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A floating rubber hose for transporting ore includes a rubber pipe and flanges with connectors at both ends of the rubber pipe. The rubber pipe, from the inside out, comprises an inner lining layer, a reinforcing layer wound around the inner lining layer, a middle lining layer covering the reinforcing layer, a foam material layer covering the middle lining layer, and an outer lining layer covering the foam material layer. The inner lining layer is distributed axially along the rubber pipe and extends to the flange surfaces at both ends. A steel wire layer composed of steel wires is provided within the reinforcing layer.

[0006] Furthermore, the steel wire layer is composed of two steel wires wound together, with a first transition adhesive layer covering the inner side of the steel wire layer and a second transition adhesive layer covering the outer side of the steel wire layer.

[0007] The two wound steel wires have the same diameter, 6-8mm.

[0008] The rubber pipe has an inner diameter of 200-400mm and a length of 6000-10000mm.

[0009] The outer coating is composed of reinforcing materials and wear-resistant and aging-resistant rubber.

[0010] The flange with connector includes a flange, connector, and retaining ring fixed to the outer circumference of the connector.

[0011] Two to four lifting lugs are welded along the circumference at the junction of the flange and the connector, with the corresponding lifting lugs at both ends on the same straight line.

[0012] The beneficial effects of this utility model are:

[0013] This utility model can withstand working pressure and the stretching and torsion of factors such as wind, waves, tides, and pipeline movement. The deformation of the pipeline cavity is small in both working and non-working states, and it will not cause abnormal explosion or wear due to excessive deformation of the pipeline cavity. Therefore, it has a long service life and is suitable for conveying materials under conditions of large wind and waves. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0015] A floating rubber hose for transporting ore includes a rubber pipe 1 and flanges 2 with connectors at both ends of the rubber pipe 1. The rubber pipe includes, from the inside out, an inner lining layer 3, a reinforcing layer 4 wrapped around the inner lining layer, a middle covering layer 5 covering the reinforcing layer, a foam material layer 8 outside the middle covering layer, and an outer covering layer 9 outside the foam material layer. The inner lining layer 3 is distributed along the axial direction of the rubber pipe 1 and extends to the surface of the flanges 2 at both ends. A steel wire layer 6 composed of steel wires is provided between the fabrics in the reinforcing layer 4.

[0016] The steel wire layer 6 is composed of two steel wires wound together. The inner side of the steel wire layer is covered with a first transition adhesive layer 71, and the outer side of the steel wire layer is covered with a second transition adhesive layer 72. The two wound steel wires have the same diameter, which is 6-8 mm.

[0017] The rubber pipe has an inner diameter of 200-400mm and a length of 6000-10000mm.

[0018] The flange 2 with connector includes a flange 21, a connector 22, and a retaining ring 23 fixed to the outer circumference of the connector 22.

[0019] At the junction of the flange 21 and the connector 22, 2-4 lifting lugs 24 are welded around the circumference, and the corresponding lifting lugs at both ends are on the same straight line.

[0020] This invention features a steel wire layer within the reinforcing layer, which improves the pipe's rigidity, enabling it to withstand working pressure and the stretching and torsion caused by factors such as wind, waves, tides, and pipeline movement. The pipe cavity exhibits minimal deformation in both working and non-working states, preventing abnormal bursting or wear due to excessive deformation, thus resulting in a long service life. It is suitable for conveying materials under conditions of strong winds and waves.
