Description

Technical Field

[0001] This invention relates to the field of power construction technology, and in particular to a high-temperature resistant traction rope. Background Technology

[0002] The shipbuilding industry plays an important role in modern socio-economic development, especially for large-tonnage ships. Other components such as boilers and engine room parts are quite large. When a malfunction occurs, these large components need to be towed and lifted out. However, these components that have just been stopped or dismantled are exposed to high temperatures. Ordinary steel wire ropes are prone to heat deformation during towing and are easily broken and damaged under tension and pull. Their impact resistance is poor, which seriously affects the effectiveness of the towing rope. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-temperature resistant traction rope.

[0004] To achieve the above objectives, the technical solution provided by this invention is: a high-temperature resistant traction rope, wherein the method for preparing the traction rope includes: First step: Twist carbon fiber filaments to form a core; The second step: The steel wire is spirally wound around the surface of the core to form a reinforcing layer. The diameter of the steel wire is 1-1.5mm and the number of wires is 3-5. Third step: Cover the core surface after the second step with a protective layer, the thickness of which is 1-3mm; Step 4: Wrap the metal fiber mesh around the surface of the protective layer to form an intermediate layer; Step 5: The metal wire is spirally wound around the surface of the intermediate layer to form a heat-conducting wire with a diameter of 1-1.5mm. The winding direction of the heat-conducting wire is opposite to that of the metal fiber mesh. After winding, a wire blank is formed. Step 6: Apply a high-temperature resistant coating to the surface of the blank to form strands; Step 7: After twisting 8-22 strands of wire in a spiral shape, wrap them with a carbon fiber mesh to form a traction rope.

[0005] The number of carbon fiber filaments in the first step is 60-99, and the filament diameter is 0.1-1mm.

[0006] The coating method in the third step includes spraying, brushing, rolling, or dipping. The components of the protective layer solution are: 5-10 parts graphite powder, 10-20 parts molybdenum disulfide, and 30-80 parts silicone rubber solution.

[0007] The intermediate layer in the fourth step is formed by spirally wrapping strips of metal fiber mesh with a width of 3-5cm. The wire diameter of the metal fiber mesh is 0.01-0.1mm, the mesh count is 500-600 mesh, and the overlap width of the edges during winding is 2-5mm.

[0008] The coating method in the sixth step includes spraying, brushing, rolling, or dipping. The components of the protective layer solution are: 5-10 parts graphite powder, 10-20 parts molybdenum disulfide, 30-80 parts silicone rubber solution, and 1-6 parts ceramic powder.

[0009] In this invention, the heat-conducting wire is used to tighten the core, intermediate layer, and reinforcing layer. At the same time, the heat-conducting wire protrudes from the surface of the core and contacts the carbon fiber mesh for heat conduction and dissipation. The high-temperature resistant layer and protective layer are used to protect the core and make the various components of the core form a whole. The carbon fiber mesh is used to protect the strands and to dissipate heat quickly. The structure after adopting this solution is reasonable, has good high-temperature resistance, and is structurally stable. Attached Figure Description

[0012] The present invention will be further described below with reference to all accompanying drawings. A preferred embodiment of the present invention is shown in the accompanying drawings. Figure 1 and appendix Figure 2 This embodiment describes a high-temperature resistant traction rope. The preparation method of the traction rope includes: a first step: twisting carbon fiber filaments to form a core; a second step: spirally winding steel wires around the surface of the core to form a reinforcing layer, the steel wire diameter being 1-1.5 mm and the number being 3-5 wires; a third step: covering the surface of the core after the second step with a protective layer, the protective layer thickness being 1-3 mm; a fourth step: spirally wrapping a metal fiber mesh around the surface of the protective layer to form an intermediate layer; a fifth step: spirally winding metal wires around the surface of the intermediate layer to form heat-conducting wires, the heat-conducting wire diameter being 1-1.5 mm, the winding direction of the heat-conducting wires being opposite to the direction of the metal fiber mesh, and forming a wire blank after winding; a sixth step: coating the surface of the wire blank with a high-temperature resistant coating to form strands; and a seventh step: spirally twisting 8-22 strands together and then covering them with a carbon fiber mesh to form a traction rope.

[0013] The first step involves 60-99 carbon fiber filaments with a diameter of 0.1-1 mm. The third step's coating method includes spraying, brushing, rolling, or impregnation. The protective layer solution comprises the following components by weight: 5-10 parts graphite powder, 10-20 parts molybdenum disulfide, and 30-80 parts silicone rubber solution. The fourth step's intermediate layer is formed by spirally winding strips of metal fiber mesh with a width of 3-5 cm. The metal fiber mesh has a wire diameter of 0.01-0.1 mm and a mesh size of 500-600, with an edge overlap width of 2-5 mm during winding. The sixth step's coating method includes spraying, brushing, rolling, or impregnation. The protective layer solution comprises the following components by weight: 5-10 parts graphite powder, 10-20 parts molybdenum disulfide, 30-80 parts silicone rubber solution, and 1-6 parts ceramic powder.

[0014] The traction rope prepared by the above method consists of an outer layer 8 and several strands located inside the outer layer 8. The outer layer 8 is formed by covering with a carbon fiber mesh. The strands include a core 1, a reinforcing layer 3 on the surface of the core 1, a protective layer 2 on the surface of the reinforcing layer 3, an intermediate layer 5 on the surface of the protective layer 2, a spiral heat-conducting wire 6 wound on the surface of the intermediate layer 5, and a high-temperature resistant layer 7 on the surface of the heat-conducting wire 6. With the above scheme, the core is formed by twisting several carbon fiber filaments, resulting in high strength and good tensile properties. The surface of the core is wrapped with steel wire (reinforcing layer) to prevent the core from unraveling. After the steel wire is wrapped, a protective layer is applied to integrate the reinforcing layer with the core. The intermediate layer is covered with a metal fiber mesh on the surface of the protective layer. The surface of the intermediate layer is then wrapped with heat-conducting wire, and finally impregnated and covered with a high-temperature resistant material to form complete strands. After twisting, the strands are covered with a carbon fiber mesh. With the above scheme, the heat-conducting wire is used to tighten the core, intermediate layer, and reinforcing layer. At the same time, the heat-conducting wire protrudes from the surface of the core and contacts the carbon fiber mesh for heat conduction and dissipation. The high-temperature resistant layer and the protective layer are used to protect the core and integrate the various components of the core. The carbon fiber mesh is used to protect the strands and also to facilitate rapid heat dissipation. The structure with this scheme is reasonable, has good high-temperature resistance, and is structurally stable.

[0015] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, any changes made in accordance with the shape and principle of the present invention should be covered within the protection scope of the present invention.
