Description
Technical Field
The utility model relates to a dredging hose, in particular to a dredging hose with a fabric-reinforced rubber baffle ring.
Background
During use, underwater pipelines or onshore pipelines may encounter the ground with height differences. In particular to a rubber pipe at the junction of land and water, the height difference of the position is larger. In these cases, the hose generally collapses due to local over-bending, forming a vortex, which accelerates the wear of the inner liner compound.
The rubber tube used for dredging construction at present is generally divided into a floating rubber tube and a non-floating rubber tube. The floating hose is used for an overwater pipeline, and the non-floating hose is used for an underwater pipeline or an overland pipeline. After forming, whether the product floats or not can not be changed any more. If the environmental conditions change and the length of the floating pipeline is required to be increased or reduced, the rubber pipe must be replaced, the original rubber pipe can only be left unused, waste is caused, the working efficiency is reduced, and the construction period is prolonged.
Disclosure of Invention
In order to overcome the above disadvantages, the present invention provides a dredging hose having a fabric-reinforced rubber grommet, which has superior bending resistance and flexibility, can change a floating state, and is suitable for use on the ground having a difference in height such as an amphibious boundary, and can also be used in an environment where buoyancy requirements are changed.
The purpose of the utility model is realized by the following technical scheme.
A dredging hose with fabric-reinforced rubber baffle ring comprises a rubber hose body and a metal flange with short connecting pipes at two ends; the pipe wall of rubber hose body is by interior to outer including inner liner, enhancement layer, outer coating, its characterized in that: a group of fabric reinforced rubber baffle rings are arranged at the outer edge of the outer coating.
Furthermore, in order to improve the bending resistance of the rubber hose 2, 6-10 fabric-reinforced rubber baffle rings are arranged on the outer edge of the outer coating of the rubber hose. The rubber retaining ring is composed of a plurality of rubber-coated cord fabric reinforcing layers and a plurality of wear-resistant and aging-resistant rubber materials which are alternately arranged.
In the utility model, the width of the rubber baffle ring is 60-100mm, and the height of the rubber baffle ring is 80-120 mm.
The plurality of fabric-reinforced rubber stopper rings arranged on the outer edge of the hose are spaced at different distances from each other. The distance between the two rubber baffle rings close to the flanges at the two ends and the two rubber baffle rings at the two sides of the midpoint line of the length of the rubber hose is smaller, about 600-800 mm, so that the rigidity and the bending resistance of the rubber hose at the positions can be improved. The distance between the rubber retaining rings of the other parts is longer, about 1000-1500 mm, and when construction needs, the parts can be provided with rubber or plastic floating bodies to enable the pipeline to be in a floating state.
The metal flange with the connecting short pipe comprises a flange plate and the connecting short pipe welded with the flange plate. The lining layer is distributed in the whole pipe length including the short connecting pipe and extends to the outer surface of the flange plate to form a rubber sealing ring 7. The sizing material of the inner liner has good abrasion resistance. Through vulcanization, the inner rubber layer and the rubber sealing ring 7 on the surface of the flange plate form a whole, so that the whole rubber hose 1 has good sealing performance.
According to the utility model, the group of fabric-reinforced rubber baffle rings are arranged on the outer side of the rubber hose body, and the existence of the rubber baffle rings improves the stiffness of the pipeline and enhances the flex resistance of the rubber hose, so that the rubber hose can be placed on the ground with height difference and in a bent state, can not collapse, and can still keep the pipeline smooth. When the rubber pipe is used for water construction, a rubber or plastic floating body can be added between the baffle rings to adjust the floating state of the pipe body, so that the pipe meets the requirement of operation.
The rubber hose body is provided with the group of fabric-reinforced rubber baffle rings, so that the stiffness of the dredged rubber hose is improved, the dredged rubber hose can still keep a pipeline smooth when being positioned on the ground with height difference or in a bending state, local vortex cannot be formed due to collapse, and the service life of the rubber hose is prolonged. Meanwhile, the floating body can be arranged between the rubber retaining rings according to the requirement of the product and connected with a floating pipeline, so that the working efficiency is improved, and the construction period is shortened.

Detailed Description
As shown in fig. 1-2, a dredging hose with fabric-reinforced rubber ring comprises a rubber hose body 1 and metal flanges 2 with connecting short pipes fixed at both ends thereof. The metal flange with the connecting short pipe comprises a flange 21 and the connecting short pipe 22 welded with the flange. The rubber hose body 1 sequentially comprises an inner liner layer 3, a reinforcing layer 4, an outer coating layer 5 and a rubber retaining ring 6 containing fabric reinforcement from inside to outside.
Further, the lining layer 3 is distributed over the entire length of the pipe, including the metal flange 21 with the junction stub 22, and extends as far as the outer surface of the flange 21 to form the sealing ring 7. The rubber material of the inner liner layer 3 has good abrasion resistance. Through vulcanization, the inner rubber layer 3 and the rubber sealing ring 7 on the surface of the flange plate 21 form a whole, so that the whole rubber hose 1 has good sealing performance.
The rubber hose is further designed in that 6-10 rubber retaining rings 6 containing fabric reinforcement are arranged on the outer edge of the rubber hose outer coating 5 in order to improve the bending resistance of the rubber hose body. The rubber retaining ring 6 is formed by alternately arranging 4-8 layers of rubber-coated cord fabric reinforced layers 61 and a plurality of layers of abrasion-resistant and aging-resistant rubber materials 62. All of the cord fabric reinforcement layers 61 are coated with a sizing 62. Each rubber baffle ring 6 has a height of 80-120mm and a width of 60-100 mm.
The distances between the fabric-reinforced rubber retaining rings arranged at the outer edge of the rubber hose are different, the distances between the two rubber retaining rings 6 close to the flanges 21 at the two ends and the distances between the two rubber retaining rings 6 at the two sides of the midpoint line of the length of the rubber hose are smaller, and are about 600-800 mm, so that the rigidity and the bending resistance of the rubber hose pipeline at the positions can be improved, and the vortex caused by over-bending can be avoided. The distance between the rubber baffle rings 6 at the other parts is longer, and is about 1000-1500 mm. When necessary, the parts can be provided with rubber or plastic floating bodies to enable the pipeline to be in a floating state.
The utility model improves the stiffness of the dredging hose, so that the dredging hose can still keep the pipeline smooth when being positioned on the ground with height difference or in a bending state, and local vortex is not formed due to collapse, thereby prolonging the service life of the hose. Meanwhile, the product can be provided with a floating body when needed and is connected with a floating pipeline.
