Description

Technical Field

[0001] The utility model relates to the technical field of plastic winding pipes, in particular to a plastic-steel fiber continuous co-extrusion reinforced winding pipe. Background Art

[0002] The spiral wound pipe is a tubular structure made by spirally winding an extruded plastic strip on a rolling device and bonding them together. Its base material is mostly PE or PP. It is a pipe with significant technical characteristics and a wide range of applications. In order to improve the ring stiffness of the pipe body, the simplest way is to increase the wall thickness of the pipe body. However, increasing the wall thickness of the pipe body will increase the material used for the spiral wound pipe, and the production cost will rise sharply. The overall weight of the spiral wound pipe will also increase, which will also bring difficulties to transportation and laying.

[0003] Therefore, the prior art discloses a FRPE reinforced composite winding pipe (authorization announcement number CN208670311U), which has a double wall and rib structure, and the space between two adjacent winding units is filled with melt glue for bonding the winding units. However, in actual use, the winding pipe of this structure is prone to cracking, resulting in the breakage and leakage of the pipe body, and its strength needs to be strengthened. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to provide a plastic-steel fiber continuous co-extruded reinforced winding tube, which effectively improves the radial load-bearing capacity and axial load-bearing capacity of the winding tube, and forms an engaging connection structure between the two plastic-steel fiber pipe bodies, so that the connection strength is better and stronger, and the service life of the winding tube is extended.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a plastic-steel fiber continuous co-extruded reinforced winding tube, which is formed by winding a plastic-steel fiber pipe body, and the overlapping parts between any two adjacent plastic-steel fiber pipe bodies are provided with molten material, which is used to bond the plastic-steel fiber pipe bodies with a sheet structure to form a winding tube with a tubular structure.

[0006] The outer side surface of the plastic-steel fiber pipe body is provided with multiple groups of reinforcing ribs, and reinforcing steel strips are co-extruded inside the reinforcing ribs. A fiber reinforcement part is provided inside the plastic-steel fiber pipe body, and the fiber reinforcement part includes fiber strips of a multi-layer structure. A flared lap joint is provided at one end of the plastic-steel fiber pipe body, and a socket lap joint is provided at the other end of the plastic-steel fiber pipe body. The inner side surface of the flared lap joint and the outer side surface of the socket lap joint are both provided with reinforcing connection parts. In the process of making the winding tube, the flared lap joint is overlapped with the outer side surface of the socket lap joint, and the reinforcing connection part provided on the flared lap joint is matched with the reinforcing connection part provided on the socket lap joint, and the molten material is provided between the two reinforcing connection parts for bonding and fusing them into one.

[0007] Preferably, the reinforced connection portion is a sawtooth structure or a rectangular tooth structure, the purpose of which is to strengthen the connection strength between two adjacent plastic-steel fiber pipe bodies.

[0008] Furthermore, the reinforcing steel belt is arranged vertically, which effectively improves the ring stiffness.

[0009] Furthermore, a semi-spherical anti-collision support portion is provided at the top of the reinforcing rib, and the top of the reinforcing steel belt is located in the anti-collision support portion. The setting of the anti-collision support portion increases the supporting bearing capacity of the top of the reinforcing steel belt, thereby avoiding damage and exposure of the top of the reinforcing steel belt.

[0010] Furthermore, the outside of each layer of the fiber strips is coated with PP molten material or PE molten material. When the main material of the plastic-steel fiber pipe body is PP material, the outside of the fiber strips is coated with PP molten material; when the main material of the plastic-steel fiber pipe body is PE material, the outside of the fiber strips is coated with PE molten material, which enables the fiber strips to better integrate with the PP main material or the PE main material, thereby improving the strength.

[0011] Furthermore, the fiber reinforcement part includes a three-layer fiber strip, and the fiber strip is a glass fiber with a thickness of 0.3 mm, and the width can be set as required.

[0012] The beneficial effects of the utility model are as follows: (1) by providing multiple groups of reinforcing ribs and providing reinforcing steel belts inside the reinforcing ribs, a spiral reinforcing structure is formed on the outside of the winding tube, which effectively improves the radial bearing capacity of the winding tube; (2) by providing a fiber reinforcement part inside the plastic-steel fiber pipe body, a horizontal reinforcing structure is formed inside the winding tube, which effectively improves the axial bearing capacity of the winding tube; (3) by providing a flared lap joint and a plug lap joint, reinforcing connection parts are provided on the inner side surface of the flared lap joint and the outer side surface of the plug lap joint, and molten material is provided between the reinforcing connection parts to form a meshing connection structure, so that the strength of the connection is better and stronger, and the service life of the winding tube is extended.

DETAILED DESCRIPTION

[0020] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] like Figures 1 to 5As shown, a plastic-steel fiber continuous co-extruded reinforced winding tube is formed by winding a plastic-steel fiber pipe body 001, and the overlapping parts between any two adjacent plastic-steel fiber pipe bodies 001 are provided with molten material 002, and the molten material 002 is used to bond the plastic-steel fiber pipe body 001 with a sheet structure to form a winding tube with a tubular structure.

[0022] The outer side of the plastic-steel fiber pipe body 001 is provided with three groups of reinforcing ribs 003, and the interior of the reinforcing ribs 003 is vertically provided with reinforcing steel belts 004. The interior of the plastic-steel fiber pipe body 001 is provided with a fiber reinforcement part 005, and the fiber reinforcement part 005 includes a three-layer structure of fiber strips 006, and the fiber strips 006 are glass fibers with a thickness of 0.3 mm.

[0023] One end of the plastic-steel fiber pipe body 001 is provided with a flared lap joint 007, and the other end of the plastic-steel fiber pipe body 001 is provided with a socket lap joint 008, and the inner side surface of the flared lap joint 007 and the outer side surface of the socket lap joint 008 are both provided with a reinforcing connection part 009. In the process of making the winding pipe, the flared lap joint 007 is overlapped with the outer side surface of the socket lap joint 008, and at this time, the reinforcing connection part 009 provided on the flared lap joint 007 is matched with the reinforcing connection part 009 provided on the socket lap joint 008, and the molten material 002 is provided between the two reinforcing connection parts 009, which bonds and fuses the two adjacent plastic-steel fiber pipe bodies 001 into one.

[0024] The reinforced connection portion 009 is a serrated structure, the purpose of which is to strengthen the connection strength between two adjacent plastic-steel fiber pipe bodies 001.

[0025] A semi-spherical anti-collision support portion 010 is provided on the top of the reinforcing rib 003, and the top of the reinforcing steel belt 004 is located in the anti-collision support portion 010.
