Description

Technical Field

[0001] This invention relates to the field of steel wire rope technology for ship loaders, and more specifically, to a fire-fighting steel wire rope for ship loaders. Background Art

[0002] Ship loaders are large-scale bulk material handling machines used for loading materials onto ships at bulk terminals. A typical ship loader consists of a boom conveyor, transition conveyor, telescopic chute, tail car, traveling mechanism, gantry, tower, pitching mechanism, and slewing mechanism. Large-scale port bulk material loading equipment plays a crucial role in the high-speed, stable, efficient, and continuous development of industries such as energy, power, metallurgy, and ports, especially in large bulk material distribution centers. Ship loaders typically operate continuously, therefore, they must be equipped with supporting equipment to provide a continuous flow of materials to enable continuous loading. Examples include grain silo feeding at grain terminals and continuous feeding of bucket wheel reclaimers in coal terminal stockyards. The development of global trade integration has promoted the global demand for bulk cargo transportation. Looking at major commodity categories, the seaborne volume of bulk cargoes such as iron ore, coal, and grain is showing a rapid growth trend. Accompanying this development is the continuous upgrading of ocean-going bulk cargo shipping vessels. The resulting construction of megaports capable of berthing and unloading these large vessels has created a demand for bulk cargo handling equipment. The increasing size of bulk carriers also presents new challenges for the design and manufacture of bulk cargo handling machinery. Based on the trends in bulk cargo automation, some development trends of ship loaders can be predicted.

[0003] Existing ship loaders require steel wire ropes to pull objects during use. Generally, steel wire ropes are made by twisting multiple layers of steel wires into strands, and then winding a certain number of strands into a spiral shape with the core as the center. In order to reduce the friction generated during use, lubricating oil needs to be filled inside the core.

[0004] However, existing wire ropes are not fire-resistant during use. Once the wire rope comes into contact with fire, it will quickly burn through the lubricating oil, which not only greatly damages the rope core but also consumes a large amount of lubricating oil. At the same time, the heat will also damage and deform the wires, seriously affecting the normal use of the wire rope. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the present invention aims to provide a fire-extinguishing steel wire rope for ship loaders. It utilizes the fusion of hydrochloric acid and sodium bicarbonate powder to generate carbon dioxide, reducing nearby oxygen-rich gases. Simultaneously, under the pressure of the steel wire tube, dry powder is sprayed out, covering a large area of ​​the steel wire rope surface, thus effectively mitigating the spread of fire. Furthermore, the addition of a flexible connecting rod significantly strengthens the stability of the steel wire rope structure, effectively preventing it from scattering during use. Finally, the reinforcing connecting piece between the two steel wire tubes effectively prevents deformation caused by the high temperatures generated when the steel wire rope encounters fire.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A fire-fighting steel wire rope for a ship loader includes multiple wound steel wire tubes and multiple spray holes drilled in the steel wire tubes. Reinforcing connecting plates are fixedly connected between the steel wire tubes. A flexible liquid storage tube is provided inside each of the steel wire tubes. Multiple evenly distributed heat-conducting tubes are inserted into the flexible liquid storage tubes. The other ends of the heat-conducting tubes are respectively inserted into the steel wire tubes. An expansion ball is provided inside the flexible liquid storage tube. Heat-conducting ropes are fixedly connected between the expansion ball and the multiple heat-conducting tubes. The flexible liquid storage tube is filled with hydrochloric acid, and the steel wire tubes are filled with sodium bicarbonate powder. The multiple heat-conducting tubes are fixedly connected to... The inner rubber tube has a ring-shaped arrangement, and each inner rubber tube is fixedly connected to multiple reinforcing connecting plates with a flexible connecting rod. It generates carbon dioxide by fusing hydrochloric acid and sodium bicarbonate powder, reducing the oxygen gas in the vicinity. At the same time, under the air pressure of the steel wire tube, the dry powder is sprayed out, covering a large area of ​​the steel wire rope surface, thus effectively mitigating the spread of fire. The flexible connecting rod greatly strengthens the stability of the steel wire rope structure, effectively preventing it from scattering during use. Furthermore, the reinforcing connecting plates connecting two steel wire tubes can effectively prevent deformation caused by the high temperature generated when the steel wire rope is exposed to fire.

[0010] Furthermore, the inner wall of the steel wire tube is fixedly connected with multiple symmetrically arranged storage films. The storage films are filled with covering dry powder, which can be sprayed out under pressure to cover the surface of the steel wire rope and slow down the spread of fire.

[0011] Furthermore, the same elastic cotton is fixedly connected to multiple of the resilient connecting rods. The elastic cotton is filled with lubricating oil, which can provide a certain lubrication for the wire rope.

[0012] Furthermore, the heat-conducting rope is made of heat-conducting adhesive and has a diameter of 0.5mm. It effectively conducts heat while also supporting the expansion ball without restricting its expansion.

[0013] Furthermore, the multiple resilient connecting rods are made of base steel and are arranged at equal intervals. The base steel has a certain degree of toughness, which causes the resilient connecting rods to deform to a certain extent when the wire rope is under stress, squeezing the elastic cotton and causing the lubricating oil inside the elastic cotton to overflow, thereby reducing the friction of the wire rope.

[0014] Furthermore, the rubber inner tube and multiple reinforcing connecting plates are all made of steel, which further enhances the stability of the wire rope structure, and the steel material has a certain tensile strength.

[0015] Furthermore, the storage film is made of an elastic film, which can increase the amount of dry powder sprayed, further enhancing its effect of slowing down the spread of fire.

[0016] Furthermore, the flexible liquid storage tube is internally fixedly connected with multiple baffles, which are located between two expansion spheres. This allows for the separation of hydrochloric acid, increases the amount of hydrochloric acid injected, and enhances the chemical reaction between hydrochloric acid and sodium bicarbonate powder.

[0017] Furthermore, the surface of the steel wire tube is coated with a layer of high-temperature color-changing paint, which can further improve the warning effect and prevent the inability to observe open flames in bright light, thus affecting the staff's ability to take further fire-fighting measures.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] (1) It generates carbon dioxide by fusing hydrochloric acid with sodium bicarbonate powder, reducing the oxygen gas in the vicinity. At the same time, under the air pressure of the steel wire tube, the dry powder is sprayed out, covering a large area of ​​the steel wire rope surface, thus effectively mitigating the spread of fire. The addition of a tough connecting rod greatly strengthens the stability of the steel wire rope structure, effectively preventing it from scattering during use. Furthermore, the reinforcing connecting piece between the two steel wire tubes effectively prevents deformation caused by the high temperature generated when the steel wire rope is exposed to fire.

[0021] (2) Multiple heat-conducting tubes are fixedly connected to the same ring-shaped rubber inner tube. The rubber inner tube and multiple reinforcing connecting plates are all fixedly connected with tough connecting rods, which can provide uniform support for the steel wire tube, thereby effectively enhancing the stability of the steel wire rope structure.

[0022] (3) Multiple symmetrically arranged storage membranes are fixedly connected to the inner wall of the steel wire rope. The storage membranes are filled with covering dry powder, which can be sprayed out under pressure to cover the surface of the steel wire rope and slow down the spread of fire.

[0024] (5) The heat-conducting rope is made of heat-conducting rubber and has a diameter of 0.5mm. It can effectively conduct heat while supporting the expansion ball and will not restrict the expansion of the ball.

[0025] (6) Multiple toughness connecting rods are made of base steel and are set at equal intervals. The base steel has a certain toughness. When the wire rope is under stress, the toughness connecting rods deform to a certain extent, squeezing the elastic cotton and causing the lubricating oil inside the elastic cotton to overflow, thereby reducing the friction of the wire rope.

[0026] (7) The rubber inner tube and multiple reinforcing connecting plates are made of steel, which further enhances the stability of the wire rope structure, and the steel material has a certain tensile strength.

[0027] (8) The storage film is made of elastic film, which can increase the amount of dry powder sprayed, further enhancing the effect of delaying the spread of fire.

[0028] (9) Multiple baffles are fixedly connected inside the flexible liquid storage tube, and the baffles are located between two expansion balls, which can separate the hydrochloric acid, increase the amount of hydrochloric acid sprayed, and enhance the chemical reaction between hydrochloric acid and sodium bicarbonate powder.

[0029] (10) The surface of the steel wire pipe is coated with a layer of high-temperature color-changing paint, which can further improve the warning effect and prevent the inability to observe open flames in bright light, thus affecting the staff's ability to take further fire-fighting measures.

[0041] Example 1:

[0042] Please see Figure 1-4A fire-fighting steel wire rope for a ship loader includes multiple wound steel wire tubes 1 and multiple spray holes 101 drilled on the steel wire tubes 1. Reinforcing connecting pieces 2 are fixedly connected between the multiple steel wire tubes 1. Flexible liquid storage tubes 3 are provided inside the multiple steel wire tubes 1. Multiple evenly distributed heat-conducting tubes 4 are inserted into the flexible liquid storage tubes 3. The other ends of the multiple heat-conducting tubes 4 are respectively inserted into the steel wire tubes 1. An expansion ball 5 is provided inside the flexible liquid storage tube 3. Heat-conducting ropes 6 are fixedly connected between the expansion ball 5 and the multiple heat-conducting tubes 4. The heat-conducting ropes 6 are made of heat-conducting rubber and have a diameter of 0.5mm. They effectively conduct heat and support the expansion ball 5 without restricting the expansion of the expansion ball 5. The flexible liquid storage tube 3 is filled with hydrochloric acid 7, and the steel wire tube 1 is filled with sodium bicarbonate powder 8. The hydrochloric acid 7 and sodium bicarbonate powder 8 are fused to produce carbon dioxide, reducing the oxygen gas in the vicinity. At the same time, under the air pressure of the steel wire tube 1, the dry powder is sprayed out, covering a large area of ​​the steel wire rope surface, thus effectively mitigating the spread of fire. The tough connecting rod 10 greatly strengthens the stability of the steel wire rope structure, effectively preventing it from scattering during use. Furthermore, the reinforcing connecting piece 2 connecting the two steel wire tubes 1 can effectively prevent deformation caused by the high temperature generated when the steel wire rope is exposed to fire.

[0043] Please see Figure 1-4 Multiple heat-conducting pipes 4 are fixedly connected to a single annular rubber inner tube 9. Each rubber inner tube 9 is fixedly connected to multiple reinforcing connecting plates 2 by a flexible connecting rod 10. Both the rubber inner tube 9 and the multiple reinforcing connecting plates 2 are made of steel, further enhancing the stability of the wire rope structure, and the steel material possesses a certain tensile strength. The multiple flexible connecting rods 10 are made of base steel and are evenly spaced. The base steel material has a certain degree of toughness, causing the flexible connecting rods 10 to deform to a certain extent when the wire rope is under stress, compressing the elastic cotton 13 and causing the lubricating oil inside the elastic cotton 13 to overflow, thereby reducing the friction of the wire rope. This provides uniform support to the wire tube 1, effectively strengthening the stability of the wire rope structure.

[0044] Please see Figure 4 Multiple symmetrically arranged storage membranes 11 are fixedly connected to the inner wall of the steel wire tube 1. The storage membranes 11 are made of elastic thin film, which can increase the amount of dry powder 12 sprayed, further enhancing the effect of delaying the spread of fire. The storage membranes 11 are filled with dry powder 12, which can be sprayed out by pressure to cover the surface of the steel wire rope and delay the spread of fire.

[0045] Please see Figure 2 Multiple flexible connecting rods 10 are fixedly connected to the same elastic cotton 13, which is filled with lubricating oil and can play a certain lubricating role for the wire rope.

[0046] Please see Figure 3 The flexible liquid storage tube 3 has multiple baffles 14 fixedly connected inside, and the baffles 14 are located between two expansion balls 5, which can separate the hydrochloric acid 7, increase the spray volume of hydrochloric acid 7, and enhance the chemical reaction between hydrochloric acid 7 and sodium bicarbonate powder 8.

[0047] Example 2:

[0048] Please see Figure 5 The difference between this embodiment and embodiment 1 is that the sodium bicarbonate powder 8 inside the steel wire tube 1 is not provided. Correspondingly, the flexible liquid storage tube 3, heat conduction tube 4, expansion ball 5, heat conduction rope 6 and hydrochloric acid 7 are removed. This makes the structure of this embodiment relatively simple and the cost lower. It can still achieve the effect of strengthening the stability of the steel wire rope structure and slowing down the fire spread rate. It is more suitable for small ship loaders or places where the service life of the steel wire rope is not relatively high.

[0049] When the steel wire tube 1 comes into contact with a heat source, the fire begins to spread due to the lubricating oil on the surface of the steel wire tube 1. Therefore, a large amount of heat is transferred to the expansion ball 5 through the heat-conducting pipe 4 and the heat-conducting rope 6, causing the expansion ball 5 to expand due to heat. (See also...) Figure 6 The flexible storage tube 3 is pressurized, causing hydrochloric acid 7 to be transferred to the inside of the steel wire tube 1 through the heat-conducting tube 4. There, hydrochloric acid 7 reacts with sodium bicarbonate powder 8 to produce a large amount of carbon dioxide, which is blown towards the surrounding fire source, reducing the amount of oxygen near the fire. Simultaneously, the pressure inside the steel wire tube 1 causes the storage membrane 11 to be squeezed, causing the dry powder covering 12 to be sprayed out through the spray hole 101, covering the surface of the steel wire rope. This device uses the fusion of hydrochloric acid 7 and sodium bicarbonate powder 8 to produce carbon dioxide, reducing the amount of oxygen in the vicinity. At the same time, the pressure in the steel wire tube 1 causes the dry powder to be sprayed out, covering a large area of ​​the steel wire rope surface, thus effectively mitigating the spread of fire. Furthermore, the addition of the flexible connecting rod 10 greatly strengthens the stability of the steel wire rope structure, effectively preventing it from scattering during use. The reinforcing connecting piece 2 connecting the two steel wire tubes 1 effectively prevents deformation caused by the high temperature generated when the steel wire rope encounters fire.

[0050] The surface of the steel wire pipe 1 is coated with a layer of high-temperature color-changing paint, which can further improve the warning effect and prevent the inability to observe open flames in bright light, thus avoiding the inability of staff to take further fire-fighting measures.

[0051] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
