Description

Technical Field

[0001] The invention belongs to the technical field of mining industry, and in particular relates to a digital maintenance device for a steel wire rope used in mining. Background Art

[0002] Steel wire ropes are usually braided from multiple steel wires, which are impregnated with lubricating oil to enhance their durability and reduce friction. Such steel wire ropes are widely used in mining, construction, transportation and other fields, playing an indispensable role.

[0003] In mining operations, wire ropes face a specific set of challenges:

[0004] First, the surface lubricant of the wire rope easily absorbs a large amount of dust particles. These particles not only increase the direct contact and wear between the steel wires, but also gradually erode the structure of the wire rope over time, thereby reducing its service life and tensile strength.

[0005] Secondly, since the mining environment is often accompanied by high temperature and high humidity conditions, this accelerates the deterioration of the lubricant. The deteriorated lubricant not only greatly reduces the lubrication effect, but may also aggravate the wear between the steel wires, further shortening the service life of the wire rope.

[0006] In view of the above problems, the wire rope needs to be lubricated regularly to maintain its good working condition and extend its service life. The process of lubricating oil replacement mainly includes cleaning impurities and old oil, and adding new oil.

[0007] However, in actual operation, due to the long-term pulling of heavy objects on the wire rope, the gap inside it is tightly compressed and mixed with old lubricating oil. This makes it difficult to effectively discharge the old oil inside when cleaning the wire rope. If the old oil cannot be completely removed, the new oil will have difficulty penetrating into the gaps between the wires, and thus cannot fully exert its lubrication and rust prevention effects.

[0008] On the other hand, if you try to clean the old oil by twisting the wire rope, it will not only be complicated and costly, but will also cause serious damage to the structural strength of the wire rope, making it difficult to put it into use again. Summary of the invention

[0009] In view of the deficiencies in the prior art, an object of the present invention is to provide a digital maintenance device for a mining wire rope.

[0010] In mining operations, wire ropes are often lubricated with semi-synthetic lubricants, which are lubricants mixed with mineral oil and synthetic oil. The base oil contains 30% to 70% synthetic oil, and the rest is mineral oil. The synthetic oil part can be poly-alpha-olefin, synthetic ester, polyether, silicone oil, etc., while the mineral oil part is a lubricant extracted from petroleum, which is prepared by adding highly lubricating nanomaterials and various additives, and has good pumpability, lubricity, extreme pressure resistance, permeability and mechanical stability.

[0011] In the present invention, the new oil is purchased from the market, and the kinematic viscosity of the new oil at 100°C is 20.44 mm 2 / s, boiling point 332°C, density 0.881g / cm 3 .

[0012] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention includes:

[0013] A cleaning container containing a cleaning liquid for cleaning old oil on the surface of the steel wire rope;

[0014] An oil change container, wherein new oil is contained in the oil change container, and an injection component is provided in the oil change container and is located in the new oil, and the injection component is used to inject auxiliary liquid into the new oil, and the temperature of the new oil is higher than the boiling point of the auxiliary liquid, so that the auxiliary liquid forms a steam explosion after contacting the new oil; the wire rope passes through the cleaning liquid and the new oil in sequence.

[0015] In the present invention, the liquid is assisted to form a steam explosion phenomenon, so that new oil can impact the steel wire rope, which helps the old oil between the steel wires to be discharged from the steel wire rope.

[0016] In the present invention, the cleaning liquid can clean the surface of the steel wire rope, thereby removing dust and part of the old oil on the surface of the steel wire rope, reducing the dust and old oil entering the oil change container, so that the old oil on the steel wire rope can be removed in batches, which can reduce the speed of mixing of the old oil into the oil change container, prolong the concentration of the new oil in the oil change container, and is beneficial to improving the oil change effect of the steel wire rope in the oil change container.

[0017] Preferably, the cleaning liquid is selected from water, and the temperature of the cleaning liquid is 60°C to 90°C.

[0018] In the present invention, the temperature of water is increased, which is conducive to washing dust and old oil from the surface of the steel wire rope.

[0019] In the present invention, the washed old oil on the steel wire rope floats on the water, which is beneficial to slowing down the volatilization consumption of water, and can also form heat insulation for water and reduce the dissipation of heat.

[0020] In the present invention, when the cleaning liquid is selected from water, the temperature of the cleaning liquid is selected from one of 60°C, 65°C, 70°C, 75°C, 80°C, 85°C, and 90°C.

[0021] In the present invention, when the cleaning liquid is selected from water, the temperature of the cleaning liquid is specifically selected to be 80°C.

[0022] Preferably, the cleaning fluid is selected from one or more of mineral oil and synthetic oil.

[0023] Preferably, the boiling point of the cleaning liquid is T, and the temperature of the cleaning liquid is 0.5T~0.7T.

[0024] In the present invention, the mineral oil is specifically selected from No. 46 white oil, which has a melting point of -20°C, a kinematic viscosity of 45.86 cSt at 40°C, and a boiling point of 221.3°C.

[0025] In the present invention, the temperature of the cleaning solution is selected from one of 110°C, 115°C, 120°C, 125°C, 130°C, 135°C, 140°C, 145°C, 150°C, and 155°C.

[0026] In the present invention, the temperature of the cleaning liquid is specifically selected to be 140°C.

[0027] Preferably, the cleaning fluid is capable of dissolving old oil.

[0028] In the present invention, mineral oil and synthetic oil have a higher boiling point, so when the temperature of the cleaning liquid is increased, the cleaning liquid evaporates less; increasing the temperature of the cleaning liquid is conducive to more fully washing away the old oil on the surface of the wire rope, thereby improving the effect of removing the old oil on the wire rope.

[0029] Preferably, a first guide component is provided in the cleaning container, and the first guide component is used to guide the steel wire rope to move forward, so that the steel wire rope is bent multiple times and the steel wire rope is always immersed in the cleaning liquid.

[0030] In the present invention, the steel wire rope is bent for many times, and the gaps between the steel wires change, which is conducive to fully washing away the dust and old oil between the steel wires, thereby improving the effect of removing the old oil on the steel wire rope.

[0031] Preferably, the temperature of the new oil is 230°C to 260°C.

[0032] In the present invention, the temperature of the new oil is selected from one of 230°C, 235°C, 240°C, 245°C, 250°C, 255°C, and 260°C.

[0033] In the present invention, the temperature of the new oil is specifically selected to be 255°C.

[0034] Preferably, the auxiliary liquid is water, and the temperature of the auxiliary liquid is 70°C to 90°C.

[0035] In the present invention, when the auxiliary liquid is water, the temperature of the auxiliary liquid is selected from one of 70°C, 75°C, 80°C, 85°C and 90°C.

[0036] In the present invention, when the auxiliary liquid is water, the temperature of the auxiliary liquid is specifically selected to be 80°C.

[0037] In the present invention, after water turns into steam, the water vapor will not liquefy because the temperature of the new oil is higher than that of water, which is beneficial to reduce the residence time of the water vapor in the new oil, thereby preventing water from mixing between the steel wires and keeping the steel wires dry.

[0038] In the present invention, the temperature of water is 70°C~90°C. Compared with water at room temperature, water at 70°C~90°C requires less heat to form water vapor, thereby increasing the intensity of water vapor explosion, and further increasing the effect of new oil impacting the wire rope. At the same time, the new oil has little heat loss, which is beneficial to reducing energy consumption and reducing the fluctuation of the new oil temperature.

[0039] Preferably, a steam delivery pipe is provided in the cleaning container, the oil change container is a closed structure, and the steam delivery pipe is connected to the top of the oil change container;

[0040] The oil change container is provided with a through hole for the steel wire rope to enter and leave, and the diameter of the through hole is 1 to 1.2 times the diameter of the steel wire rope.

[0041] In the present invention, the steam formed by the liquid-assisted steam undergoes heat exchange after entering the steam delivery pipe, thereby realizing the reuse of heat, which is beneficial to reducing the energy consumption of the digital maintenance device for the mining wire rope; at the same time, the liquid-assisted steam can heat the water without the need for additional water heating components, which is beneficial to reducing the structural complexity and production cost of the digital maintenance device for the mining wire rope.

[0042] Preferably, a second guide component is provided in the oil change container, and the second guide component is used to guide the steel wire rope to be immersed in the new oil, and the length of the steel wire rope immersed in the new oil is L1.

[0043] Preferably, a third guide component is provided in the oil change container, and the third guide component is used to guide the wire rope to travel, so that the length of the wire rope immersed in the new oil is L2, and L2>L1.

[0044] In the present invention, increasing the length of the steel wire rope entering the new oil is beneficial to increasing the probability of the new oil impacting the steel wire rope, thereby increasing the impact strength of the steel wire rope and improving the effect of replacing the old oil of the steel wire rope.

[0045] Preferably, the number of the injection component is at least one.

[0046] Preferably, the oil change container is provided with a heating component, and the heating component is used to heat the new oil.

[0047] Preferably, the oil change container is provided with a temperature sensor for monitoring the temperature of the new oil.

[0048] In the present invention, the temperature of the new oil is measured by a temperature sensor, so that the temperature of the new oil can be known, and the speed of heating the new oil can be adjusted according to actual needs.

[0049] Compared with the prior art, the advantages of the present invention include:

[0050] (1) The present invention provides a digital maintenance device for a steel wire rope for mining. New oil can impact the steel wire rope, so that the old oil inside the steel wire rope is flushed out and the new oil is flushed in to replace the old oil, thereby achieving the purpose of replacing the old oil with new oil;

[0051] (2) The digital maintenance device for a mining wire rope provided by the present invention cleans the old oil by impacting the old oil with new oil, replacing the existing operation of changing the structural shape of the wire rope itself, so that the inside of the wire rope can be cleaned without damaging the overall structural strength of the wire rope, thereby ensuring the subsequent use quality of the wire rope;

[0052] (3) The digital maintenance device for a mining wire rope provided by the present invention can eliminate the residual stress of long-term work after the wire rope is subjected to high temperature in a cleaning container and an oil change container in turn, because under high temperature conditions, no other substances will remain on the wire rope except new oil, and this operation mode can be operated continuously;

[0053] (4) The present invention provides a digital maintenance device for a mining wire rope, wherein the cleaning container can conveniently recycle old oil, and the oil change container can maintain the concentration of new oil. It does not require twisting and will not damage the original structure, thereby achieving the purpose of cleaning and maintenance while being able to recycle old oil.

[0100] Preferably, the oil change container 3 is provided with a heating component, and the heating component is used to heat the new oil.

[0109] S3, inject new oil into the oil change container 3, then reseal the top cover 31, inject hot liquid into the channel, and pay attention to the temperature of the new oil;

[0110] S4. Wait until the temperature of the new oil rises to 260°C, then start the negative pressure pump and the high-temperature water delivery pump 6 in sequence, drive the wire rope 2 to move forward, and control the temperature of the new oil to be stable at around 255°C.

[0111] When it is necessary to replace the new oil in the oil change container 3, the bolt 32 is unscrewed and removed from the oil change container 3, and after the new oil in the oil change container 3 is extracted, a proper amount of new oil is poured into the oil change container 3, and then the top cover 31 is covered and the bolt 32 is screwed into the oil change container 3 again to form a closed space. Example
