Description

Technical Field

[0001] This utility model relates to the field of sewage repair hose technology, specifically a spiral reinforced sewage repair hose structure. Background Technology

[0002] Currently, municipal pipelines and industrial sewage pipelines are prone to internal wall damage, leakage, and even structural instability during long-term use due to factors such as aging, corrosion, and mechanical damage. To extend the service life of pipelines and reduce the costs and disturbances caused by excavation and maintenance, the trenchless technology of internal lining inversion repair is often used. This method involves inserting a pre-coated flexible hose into the pipeline to be repaired and fitting it against the inner wall to form a new internal lining structure, thereby restoring the seal and strength.

[0003] Traditional reinforcing ribs often use rigid plastic strips or steel bars, which are prone to bending or breaking during the backflush and flipping process of the hose. This can lead to uneven adhesion or even damage to the hose itself, resulting in limited adhesion strength between the hose and the inner wall of the old pipe. It is difficult to achieve uniform support and long-term stable fixation, thus affecting the repair effect. At the same time, the connection structure of existing repair devices at the pipe interface is relatively complex, making operation inconvenient and limiting construction efficiency and the reusability of hoses.

[0004] Therefore, it is necessary to design a spiral-reinforced sewage repair hose structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a spiral reinforced ribbed sewage repair hose structure to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spiral reinforced rib type sewage repair hose structure, including a wear-resistant component, a hose body is fitted inside the wear-resistant component, and a spiral reinforced rib tube is fixedly connected between the hose body and the wear-resistant component. One end of the spiral reinforced rib tube is connected to an air inlet, and a sealing bolt is threaded into one end of the air inlet. A fitting component is fitted inside the hose body. A fixing ring is fixedly connected to one side of the hose body, and two symmetrical second inserts are fixedly connected to the outer surface of the fixing ring. A first arc-shaped block and a second arc-shaped block are sleeved on the outer surface of the fixing ring. A screw is threaded into the top of the first arc-shaped block, and a knob is fixedly connected to one end of the screw. One end of the screw is threaded into the interior of the second arc-shaped block. A first insert is fixedly connected to the bottom end of the second arc-shaped block, and an insertion hole is opened at the bottom end of the first arc-shaped block. The first insert is slidably inserted into the interior of the insertion hole.

[0007] Preferably, the spiral reinforcing rib is disposed between the hose body and the wear-resistant part, and one end of the air inlet extends through the outside of the wear-resistant part.

[0008] Preferably, the fixing ring is annular in shape, and both the first arc-shaped block and the second arc-shaped block are arc-shaped, with the interior of both the first arc-shaped block and the second arc-shaped block fitting against the outer surface of the fixing ring.

[0009] Preferably, the wear-resistant part is made of nitrile rubber, and the thickness of the wear-resistant part is 2.5mm-3.5mm.

[0010] Preferably, the material of the bonding component is short fiber polyester fabric, and the thickness of the bonding component is 3.2mm-3.5mm.

[0011] Preferably, the fixing ring protrudes beyond one end of the hose body and the wear-resistant component, and one side of the outer surface of the first arc-shaped block and the second arc-shaped block is flush with one side of the fixing ring.

[0012] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0013] This invention features an inflatable spiral reinforcing rib between the hose body and the wear-resistant component. Combined with an inflation port and sealing bolt structure, this allows the hose to achieve enhanced inner lining support through air pressure after bonding, avoiding the problem of easy breakage of traditional rigid reinforcing ribs during construction. The hose surface is equipped with a wear-resistant component made of nitrile rubber, which has good wear resistance and flexibility, improving the overall service life. At the same time, the fixing ring, arc-shaped block, and knob structure enable quick docking and installation of the hose and the pipe to be repaired, improving construction efficiency and convenience.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3 This utility model provides a spiral reinforced sewage repair hose structure, including a wear-resistant component 3. A hose body 1 is fitted inside the wear-resistant component 3, and a spiral reinforcing rib tube 9 is fixedly connected between the hose body 1 and the wear-resistant component 3. One end of the spiral reinforcing rib tube 9 is connected to an air inlet 10, and a sealing bolt 11 is threaded into one end of the air inlet 10. A fitting component 2 is fitted inside the hose body 1, and a fixing ring 12 is fixedly connected to one side of the hose body 1. Two symmetrical second inserts 13 are fixed to the outer surface of the fixing ring 12, and a first arc-shaped block 4 and a second arc-shaped block 5 are sleeved on the outer surface of the fixing ring 12. A screw 6 is threaded into the top of the first arc-shaped block 4, and a knob 7 is fixed to one end of the screw 6. The other end of the screw 6 is threaded into the interior of the second arc-shaped block 5. A first insert 8 is fixed to the bottom end of the second arc-shaped block 5, and an insertion hole is provided at the bottom end of the first arc-shaped block 4. The first insert 8 is slidably inserted into the interior of the insertion hole. The first arc-shaped block 4 and the second arc-shaped block 5 are fitted with the fixing ring 12, and the first arc-shaped block 4 and the second arc-shaped block 5 are threadedly connected to the fixing ring 12 by rotating the knob 7. This facilitates the connection of the first arc-shaped block 4 and the second arc-shaped block 5 to one end of the pipe to be repaired, making it easier for the subsequent pipe to be sent into the interior of the repaired pipe. Epoxy resin is then applied to the interior of the bonding component 2. Using a device such as an air pump, the wear-resistant component 3 and the hose body 1 are back-flushed into the interior of the repaired pipe, thus bonding the bonding component 2 to the inner wall of the repaired pipe. After the bonding is stable, the threads of the sealing bolt 11 are unscrewed, allowing gas to be injected into the air inlet 10, inflating the entire spiral reinforcing tube 9. The spiral reinforcing tube 9 provides support between the entire hose body 1 and the wear-resistant component 3, improving the overall service life of the device. Furthermore, after the pipe repair is completed, the first arc-shaped block 4 and the second arc-shaped block 5 can be separated and removed, completing the overall bonding of the bonding component 2 to the inner wall of the pipe, thereby improving the overall repair efficiency and service life.

[0021] By using the inflation and deflation of the spiral reinforcing tube 9, the problem of traditional reinforcing ribs being easily damaged when they are inserted into the repair pipe is avoided when the wear-resistant part 3 and the fitting part 2 are inserted as a whole. The spiral reinforcing tube 9 is set between the hose body 1 and the wear-resistant part 3, and one end of the inflation port 10 extends through the outside of the wear-resistant part 3.

[0022] To facilitate the connection between the device and the repair pipe and improve the pipe repair efficiency, the fixing ring 12 is annular in shape, and the first arc block 4 and the second arc block 5 are both arc-shaped, and the interior of the first arc block 4 and the second arc block 5 are in contact with the outer surface of the fixing ring 12.

[0023] In order to improve the overall wear resistance of the device after bonding, the wear-resistant part 3 is made of nitrile rubber and the thickness of the wear-resistant part 3 is 2.5mm-3.5mm.

[0024] In order to improve the adhesion between the device and the inside of the repair pipe after the device is inserted into the pipe, the material of the bonding component 2 is short fiber polyester fabric, and the thickness of the bonding component 2 is 3.2mm-3.5mm.

[0025] To further improve the ease of connection between the device and the pipeline to be repaired before pipeline repair, the fixing ring 12 protrudes outside one end of the hose body 1 and the wear-resistant part 3, and one side of the outer surface of the first arc-shaped block 4 and the second arc-shaped block 5 is flush with one side of the fixing ring 12.

[0026] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0027] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0028] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
