AI Technical Summary
When the existing steel wire rope reinforced polyester fiber flexible composite mesh is pulled, the stress is concentrated at the intersection of longitudinal fibers and transverse fibers, which can easily lead to fracture.
A combined structure of polyethylene reinforced mesh and steel wire mesh is adopted, where the polyethylene reinforced mesh is interwoven and molded by transverse and longitudinal polyethylene strips, and after interwoven, a flexible reinforced mesh is formed in the installation chamber. The steel wire mesh is interwoven and molded by transverse and longitudinal wire rope. It is also covered by a polyethylene reinforced mesh, and the transverse and longitudinal wire ropes are embedded in the plug-in cavity. The flexible reinforced mesh is fixed in the chamber and a mesh hole is opened to disperse stress.
Effectively dispersing stress, the overall strength of the flexible composite net of polyester fiber can be enhanced by steel wire ropes for coal mines, avoiding fractures at the intersections of longitudinal and transverse polyethylene strips, and improving tensile strength.

DETAILED DESCRIPTION
[0039] 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.
[0040] Embodiment 1
[0041] In the prior art, transverse fibers and longitudinal fibers made of polyester fibers (i.e., terylene) are interwoven horizontally and vertically to form a number of hollow spaces. Therefore, when the steel wire rope reinforced polyester fiber flexible composite net for coal mines is pulled, the stress will be concentrated at the intersection of each transverse fiber and longitudinal fiber. Under the action of stress, the intersection of the transverse fiber and the longitudinal fiber is easily broken.
[0042] In order to solve the above technical problems, the inventors have adopted the following technical solutions, which are as follows:
[0043] like Figure 1-5 As shown, the utility model provides a technical solution:
[0044] Steel wire rope reinforced polyester fiber flexible composite mesh for coal mines, including:
[0045] The polyethylene reinforcement net is formed by woven transverse polyethylene strips 10 and longitudinal polyethylene strips 20, and the transverse polyethylene strips 10 and longitudinal polyethylene strips 20 are integrally formed;
[0046] Wherein, after the transverse polyethylene strips 10 and the longitudinal polyethylene strips 20 are interwoven horizontally and vertically, a plurality of installation chambers 50 are formed between the transverse polyethylene strips 10 and the longitudinal polyethylene strips 20;
[0047] Wherein, a flexible reinforcing net 60 is installed in each installation chamber 50. When the steel wire rope reinforced polyester fiber flexible composite net for coal mine is pulled, each flexible reinforcing net 60 can disperse the stress on the polyethylene reinforcing net, especially can avoid the stress concentration at the intersection of each transverse polyethylene strip 10 and the longitudinal polyethylene strip 20, so that the overall strength of the steel wire rope reinforced polyester fiber flexible composite net for coal mine is higher, so that the intersection of the transverse polyethylene strip 10 and the longitudinal polyethylene strip 20 is not easy to break;
[0048] and a steel wire mesh, which is formed by traverse steel wires 30 and longitudinal steel wires 40 interwoven horizontally and vertically, and the traverse steel wires 30 and longitudinal steel wires 40 are integrally formed;
[0049] The polyethylene reinforcing mesh is wrapped around the outside of the steel wire mesh. After the polyethylene reinforcing mesh is wrapped around the steel wire mesh, each transverse polyethylene strip 10 is wrapped around the corresponding transverse steel wire rope 30 , and each longitudinal polyethylene strip 20 is wrapped around the corresponding longitudinal steel wire rope 40 .
[0050] Since the transverse polyethylene strips 10 and the longitudinal polyethylene strips 20 in the polyethylene reinforcement net are integrally formed, the polyethylene reinforcement net has a higher tensile strength; since the transverse steel wire ropes 30 and the longitudinal steel wire ropes 40 in the steel wire net are integrally formed, the steel wire net has a higher tensile strength.
[0051] Embodiment 2
[0052] like Figure 1-5 As shown, based on the first embodiment, the following improvements are made:
[0053] In order to enable the steel mesh to be installed in the polyethylene reinforcement mesh, the inventors, in this embodiment, further, the shape and size of the polyethylene reinforcement mesh are equal to the shape and size of the steel mesh.
[0054] Furthermore, each transverse polyethylene strip 10 is provided with a transverse plug-in cavity 101, and each transverse steel wire rope 30 is embedded in the corresponding transverse plug-in cavity 101;
[0055] A longitudinal plug-in cavity 201 is defined in each longitudinal polyethylene strip 20 , and each longitudinal steel wire rope 40 is embedded in the corresponding longitudinal plug-in cavity 201 .
[0056] In order to improve the strength of the polyethylene reinforcing mesh, the inventors, in this embodiment, further, each transverse polyethylene strip 10 and longitudinal polyethylene strip 20 has a rectangular cross section.
[0057] Since the cross-sections of the transverse polyethylene strips 10 and the longitudinal polyethylene strips 20 are both rectangular, four edges are formed on the edges of each transverse polyethylene strip 10 and the longitudinal polyethylene strip 20, and these four edges form four reinforcing ribs. Therefore, the overall strength of the polyethylene reinforcing net is higher.
[0058] In order to optimize the fixing form of each flexible reinforcing net 60 and the polyethylene reinforcing net, the inventors, in this embodiment, further, each flexible reinforcing net 60 is fixedly installed in the corresponding installation cavity 50, and after fixation, the edge of each flexible reinforcing net 60 is integrally formed with the corresponding installation cavity 50.
[0059] Embodiment 3
[0060] like Figure 1-5 As shown, based on the second embodiment, the following improvements are made:
[0061] In order to improve the tensile strength of the flexible reinforcing net 60 , the inventors, in this embodiment, further, each flexible reinforcing net 60 is provided with a plurality of mesh holes 601 , each mesh hole 601 is diamond-shaped, and the mesh holes 601 can disperse the stress on the flexible reinforcing net 60 .
[0062] More specifically, the side length of each mesh hole 601 is 3 mm to 6 mm.
[0063] In order to optimize the specific form of the flexible reinforcing net 60, the inventors, in this embodiment, further, each flexible reinforcing net 60 is a polyester fiber reinforcing net.
[0064] In order to enhance the overall strength of the flexible reinforcing net 60, the inventors, in this embodiment, further, provide that the thickness of each polyester fiber reinforcing net is 5 mm-10 mm.
[0065] In summary, the workflow of the utility model is:
[0066] like Figure 1-5 As shown, since the transverse polyethylene strips 10 and the longitudinal polyethylene strips 20 in the polyethylene reinforcement net are integrally formed, the polyethylene reinforcement net has a higher tensile strength; since the transverse steel wire ropes 30 and the longitudinal steel wire ropes 40 in the steel wire net are integrally formed, the steel wire net has a higher tensile strength.
[0067] After the transverse polyethylene strips 10 and the longitudinal polyethylene strips 20 are interwoven horizontally and vertically, a plurality of installation chambers 50 are formed between the transverse polyethylene strips 10 and the longitudinal polyethylene strips 20, wherein a flexible reinforcing net 60 is installed in each installation chamber 50. When the steel wire rope reinforced polyester fiber flexible composite net for coal mines is pulled, each flexible reinforcing net 60 can disperse the stress on the polyethylene reinforcing net, especially can avoid stress concentration at the intersection of each transverse polyethylene strip 10 and the longitudinal polyethylene strip 20, thereby making the overall strength of the steel wire rope reinforced polyester fiber flexible composite net for coal mines higher, so that the intersection of the transverse polyethylene strips 10 and the longitudinal polyethylene strips 20 is not easy to break.
[0068] Each flexible reinforcing net 60 is provided with a plurality of mesh holes 601, each mesh hole 601 is in a diamond shape, and the mesh holes 601 can disperse the stress on the flexible reinforcing net 60;
[0069] Specifically, each flexible reinforcement net 60 is a polyester fiber reinforcement net.
[0070] The above different embodiments can be combined, replaced and used in conjunction with each other.
