[0001] The utility model relates to the technical field of composite pipes, in particular to a PTFE-lined steel wire-reinforced polyethylene composite wear-resistant pipe. Background Art

[0002] The wire mesh skeleton polyethylene composite pipe is a new type of pipe that uses a mesh skeleton formed by left and right spiral winding of high-strength steel wire as a reinforcement, high-density polyethylene as a matrix, and high-performance HDPE modified adhesive resin to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene.

[0003] After searching, a Chinese patent discloses a highly wear-resistant polyethylene steel wire composite pipe (publication number CN216344405U). The combination of the spring and the buffer arc frame in this patented technology strengthens the buffering force on the pipe body, strengthens the protection of the pipe body, and reduces the impact of the outside on the pipe body. However, the connection strength between the inner and outer layers of polyethylene and the steel wire mesh skeleton in the existing structure is low, and it is easy to cause separation after being impacted. Therefore, the technicians in this field provide a PTFE-lined steel wire reinforced polyethylene composite wear-resistant pipe to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a PTFE-lined steel wire reinforced polyethylene composite wear-resistant pipe in order to solve the above problems, thereby improving the problem of low connection strength between the inner and outer polyethylene layers and the steel wire mesh skeleton in the existing structure.

[0006] Preferably, a mounting block is fixedly connected to a side of the connecting plate away from the steel wire skeleton layer, and the mounting block is fixedly connected to an inner wall of an adjacent base layer.

[0007] Preferably, two symmetrically distributed connecting parts are fixedly connected to one side of the mounting block close to the steel wire skeleton layer, and one end of the connecting part away from the mounting block is bent to form a bent part.

[0008] Preferably, evenly distributed cavities are opened inside the surface layer, and the interior of the cavities is filled with a repair agent.

[0009] Preferably, the inner lining layer is a PTFE material component, and one end of the inner lining layer extends to the inner edge of the end plate and is fixedly connected to the inner edge of the end plate.

[0010] Preferably, the number of the connecting plates in each group is not less than eight, and the connecting plates in each group are distributed in a ring shape with the steel wire skeleton layer as the center.

[0011] The beneficial effects of the utility model are:

[0012] 1. By setting up the reinforcement components, the connection area between the steel wire skeleton layer and the two base layers can be increased under the action of the connection plate, the mounting block and the connection part, the connection strength between the steel wire skeleton layer and the two base layers can be strengthened, and the possibility of the two falling off can be reduced. The setting of the bending part can provide a pulling force to the steel wire skeleton layer on the two base layers, further strengthening the connection strength between the two.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] When implementing: Figure 1-5 As shown, a PTFE-lined steel wire reinforced polyethylene composite wear-resistant pipe comprises: a steel wire skeleton layer 1 and an end plate 104, wherein a surface layer 102 is arranged on the outer edge of the steel wire skeleton layer 1, an inner lining layer 103 is arranged on the inner edge of the steel wire skeleton layer 1, and a base layer 101 is arranged between the surface layer 102 and the steel wire skeleton layer 1 as well as between the inner lining layer 103 and the steel wire skeleton layer 1; a reinforcing component 2, wherein the reinforcing component 2 is arranged on the surface of the end plate 104, and the reinforcing component 2 is used to strengthen the connection strength between the steel wire skeleton layer 1 and the base layer 101; wherein the reinforcing component 2 comprises two groups of connecting plates 201 respectively arranged on the outer edge and the inner edge of the steel wire skeleton layer 1, the connecting plate 201 extends from one side of the steel wire skeleton layer 1 away from the inside of the adjacent base layer 101, and one end of the connecting plate 201 is fixedly connected to the surface of the end plate 104.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a mounting block 202 is fixedly connected to one side of the connecting plate 201 away from the steel wire skeleton layer 1, and the mounting block 202 is fixedly connected to the inner wall of the adjacent base layer 101. Two symmetrically distributed connecting portions 203 are fixedly connected to one side of the mounting block 202 close to the steel wire skeleton layer 1, and one end of the connecting portion 203 away from the mounting block 202 is bent to form a bent portion 204. The number of each group of connecting plates 201 is not less than eight, and each group of connecting plates 201 is distributed in a ring with the steel wire skeleton layer 1 as the center.

[0023] The arrangement of the mounting block 202 and the connecting plate 201 can increase the connection area between the steel wire skeleton layer 1 and the base layer 101, and strengthen the connection strength between the two. Specifically, the base layer 101 is a polyethylene material component, and the connection strength between the two can be further strengthened through the bending portion 204, so that it can hook the base layer 101. When the base layer 101 is separated from the steel wire skeleton layer 1, it can hook the base layer 101 under the action of the bending portion 204, thereby further strengthening the connection strength between the two.

[0024] like Figure 1 , Figure 2 and Figure 5As shown, the surface layer 102 is provided with uniformly distributed cavities 105, the cavities 105 are filled with a repair agent, the inner lining layer 103 is a PTFE material component, one end of the inner lining layer 103 extends to the inner edge of the end plate 104 and is fixedly connected to the inner edge of the end plate 104;

[0025] The setting of the cavity 105 can provide a certain buffer space when the surface layer 102 is impacted, and the repair agent filled inside can be used to repair the cracks in the surface layer 102 when the surface layer 102 is damaged and cracks are generated, thereby increasing the service life.

[0026] When the utility model is in use, it can strengthen the connection area between the steel wire skeleton layer 1 and the base layer 101 under the action of the reinforcing component 2, and strengthen the connection strength between the two. At the same time, a certain pulling force is formed on the base layer 101 under the action of the bending part 204, which further strengthens the connection strength between the steel wire skeleton layer 1 and the base layer 101 and avoids the possibility of falling off and separation during use. The cavity 105 can provide a certain buffer space when the surface layer 102 is impacted, and the repair agent filled inside can be used to repair the cracks in the surface layer 102 when the surface layer 102 is damaged and cracks are generated. The repair agent inside the adjacent cavity 105 can be used to repair the cracks in the surface layer 102, thereby improving the service life.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
