Description

Technical Field

[0001] This invention relates to the field of crane wire rope maintenance technology, and in particular to an oil immersion device and method for crane wire ropes. Background Technology

[0002] Cranes are widely used in petroleum, mining, ports, civil engineering, and industrial production, and crane wire ropes are one of the most important pieces of equipment. Generally, crane wire ropes are characterized by frequent use and heavy loads. Under these characteristics, the diameter of such wire ropes is generally 16-28mm, and the length is 185-1250m. To ensure safety during use, wire ropes need to be maintained frequently. Applying surface grease during wire rope maintenance is a very important maintenance procedure. Currently, the conventional method used in China is immersion oiling: the tensioned wire rope is forcibly pressed into a grease bath for immersion. This method provides a thorough coating and good results, but because the wire rope is forcibly pressed in, it forms a "U"-shaped bend, generating bending stress and affecting the service life of the wire rope. In addition, this immersion oiling device occupies a large area and consumes a lot of energy. To overcome the above-mentioned shortcomings, some companies have chosen to use patent number 201821825547.5, entitled "A Steel Wire Rope Maintenance Equipment with a Decontamination Device." This equipment can remove contaminants from the steel wire rope while simultaneously immersing it in oil. However, crane steel wire ropes are characterized by their large diameter and long length, leading to the following drawbacks when using this equipment: 1. The long length of the crane steel wire rope requires a large amount of lubricating oil during immersion, resulting in high maintenance costs; 2. The large diameter and long length of the crane steel wire rope necessitate a lengthy process of oil absorption and self-control after immersion to ensure normal operation, which is time-consuming; 3. The long length of the crane steel wire rope means that conventional oil absorption and self-control methods cannot prevent lubricating oil from dripping onto the ground during use, causing environmental pollution. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects in the prior art and provide an oil-immersing device and method for crane wire ropes that achieves maximum recovery of lubricating oil by combining a wave-shaped oil-immersing body with an oil removal device, thereby saving lubricating oil, reducing maintenance costs, and enabling the rapid use of crane wire ropes after oil immersion to prevent environmental pollution.

The waste gas pipe is connected to the inlet of the activated carbon storage tank through an induced draft fan, and the outlet of the activated carbon storage tank is connected to a gas discharge pipe.

[0009] Preferably, the oil removal device includes an oil removal housing, inside which are provided a primary oil removal component and a secondary oil removal component. The inlet end of the oil removal housing is lower than the outlet end of the oil removal housing. The inlet end of the oil removal housing is connected to the end of the downwardly extending connecting portion housing. An oil receiving groove is provided on one side of the inlet end of the oil removal housing at the connection point, and the bottom of the oil receiving groove is connected to an oil receiving box. A downwardly extending connecting portion housing is provided in the middle of the housing. A fourth steel wire rope guide wheel is provided at the outlet end of the oil removal housing.

[0010] Preferably, the primary degreasing component, the first degreasing component, and the secondary degreasing component have the same structure, including a lower degreasing plate with a support plate and an upper degreasing plate with a bolt rod. The upper part of the bolt rod passes through the corresponding oil immersion housing and the degreasing housing. The bolt rod on the outside of the oil immersion housing and the degreasing housing has a height adjustment nut.

[0011] Preferably, the lower degreasing plate has a lower degreasing groove at the top center and the upper degreasing plate has an upper degreasing groove at the bottom center. The inner walls of the lower and upper degreasing grooves are respectively provided with rubber wear-resistant layers. The upper and lower degreasing plates are staggered, with the upper degreasing plate at the front and the lower degreasing plate at the rear.

[0012] Preferably, the wire rope pressing and oil-immersing component includes a pressing block, a first screw at the top of the pressing block, the upper part of the first screw passing through the oil-immersing housing, and a first adjusting nut at the top of the first screw; sliders are respectively provided on both sides of the pressing block, and the ends of the sliders are respectively adapted to the grooves in the corresponding guide blocks; the top of the guide blocks is connected to the inner wall of the oil-immersing housing.

[0013] Preferably, the downward pressure wire rope guide includes a downward pressure channel steel, the top of which is provided with a second screw, the upper part of which passes through the downward extension connecting housing, and the top of which is provided with a second adjusting nut.

[0014] The present invention also provides an oil-immersion method for an oil-immersion device for crane wire ropes, the oil-immersion method comprising the following steps:

[0015] Step 1: The steel wire rope to be immersed in oil passes between the third steel wire rope guide wheel and the brush. The brush removes burrs from the surface of the steel wire rope. Then, the steel wire rope is guided into the immersion body through the lower part of the channel steel. The brush is a steel wool ball or a steel wire brush. The channel steel is movably set with the movable shaft. The channel steel presses down on the top of the steel wire rope to be immersed in oil by its own weight. It can be adjusted according to the diameter of the steel wire rope to be immersed in oil, and removes burrs from the surface of the steel wire rope while achieving the guiding function.

[0016] Step 2: The steel wire rope to be immersed in oil enters the degreasing device through the upper part of the first steel wire rope guide wheel, the lower part of the steel wire rope pressing oil-immersing component, between the primary degreasing components, the upper part of the second steel wire rope guide wheel, and the lower pressing steel wire rope guide component. The steel wire rope to be immersed in oil is guided by the upper part of the first steel wire rope guide wheel and pressed into the grease by the lower part of the steel wire rope pressing oil-immersing component. After immersion in oil, the steel wire rope continues to move forward and comes into contact with the rubber wear-resistant layer on the inner wall of the lower and upper degreasing tanks for degreasing. Excess grease flows back into the corresponding grease tank at the upper part of the grease heating device for continued use. The steel wire rope passing through the primary degreasing component enters the degreasing device under the guidance of the second steel wire rope guide wheel and the lower pressing steel wire rope guide component. During this process, the dripping grease enters the oil receiving tank along the inner wall of the connecting part housing under the action of gravity.

[0017] Step 3: During the operation of Step 2 above, the grease heating device continuously heats the grease in the grease tank. The flue gas generated by heating is adsorbed in the activated carbon storage tank through the exhaust pipe under the action of the induced draft fan, and then discharged through the gas exhaust pipe.

[0018] Step 4: The oil-soaked wire rope passes sequentially between the lower and upper degreasing grooves of the primary degreasing unit and between the lower and upper degreasing grooves of the secondary degreasing unit. The two degreasing units have a limiting and guiding function while removing oil, and finally the oil-soaked wire rope is connected to the subsequent power collection section through the fourth wire rope guide wheel.

[0019] Step 5: When the wire rope described in Steps 2 and 3 passes through the primary degreasing unit, the first degreasing unit, and the second degreasing unit, the wire rope first contacts the rubber wear-resistant layer in the upper degreasing groove, causing excess grease on the upper circumferential surface of the wire rope to drip off and / or enter the lower circumferential surface of the wire rope under the combined action of gravity and the rubber wear-resistant layer. Then it contacts the rubber wear-resistant layer in the lower degreasing groove, causing excess grease on the lower circumferential surface of the wire rope to drip off under the combined action of gravity and the rubber wear-resistant layer.

[0020] Step 6: The grease dripping from the wire rope after passing through the primary and secondary degreasing components in Step 3 enters the oil collecting trough by gravity at the inlet end of the degreasing housing, which is lower than the outlet end of the degreasing housing. The grease in the oil collecting trough eventually enters the oil collecting box for recycling and reuse.

[0021] According to the above scheme, an oil-immersing device and method for crane wire ropes are manufactured. The invention includes an oil-immersing body, which has a wave-shaped structure with one end upwards and the other downwards. Specifically, the oil-immersing body includes an oil-immersing section shell with a "V"-shaped front end, and a downwardly extending connecting section shell integrally formed with the oil-immersing section shell at its end. In this structure, the middle part of the oil-immersing section shell is the oil-immersing area for the wire rope. A primary degreasing component is provided at the rear middle position of the oil-immersing section shell, enabling the removal of most of the grease from the wire rope and effective recovery using the grease's own gravity. A waste gas collection and treatment unit is provided at the rear of the oil-immersing section shell to collect and treat waste gas. The invention also includes a deburring guide unit at the front of the oil-immersing body. This not only allows the wire rope to smoothly enter the oil-immersing body but also removes burrs from the wire rope, preventing subsequent impacts. The invention extends the service life of the wire rope guide wheel or degreasing components and other related equipment. Furthermore, the degreasing device described in this invention is tightly integrated with the downwardly extending connecting housing in the oil-immersing body. Specifically, the wire rope enters the degreasing device through the close cooperation of the second wire rope guide wheel and the downward-pressing wire rope guide. The degreasing device includes primary and secondary degreasing components, which, in conjunction with the degreasing device (inclined towards the front end) and the downwardly extending connecting housing, allow the grease removed from the wire rope to enter the oil collection tank under gravity for easy recycling. The degreasing component in this invention preferably degreases the upper part of the wire rope first, then the lower part, and uses a two-sided degreasing mechanism to prevent oil dripping and environmental pollution during wire rope use. It features a simple structure, reasonable design, efficient grease recovery while rapidly immersing the wire rope in oil, effective waste gas treatment, and environmental friendliness.

[0031] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1-8 This invention relates to an oil-immersing device and method for crane wire ropes. The device includes an oil-immersing body 1, with a deburring guide unit at the front, a waste gas collection and treatment unit at the top, and an oil removal device at the end. The oil-immersing body 1 includes an oil-immersing housing 21 with a "V"-shaped front end, and a downwardly extending connecting housing 22 integrally formed with the oil-immersing housing 21 at its end. This invention is an oil-immersing device designed based on the oil-immersing body 1. By incorporating the downwardly extending connecting housing 22 and the oil removal device, it removes oil from the oil-immersed wire rope and recovers the lubricating oil, thereby reducing maintenance costs, preventing oil dripping from the wire rope, and enabling the crane wire rope to be used quickly after oil immersion.

[0033] Furthermore, a first wire rope guide wheel 2 is provided at the inlet of the front end of the oil-immersing housing 21, and a grease heating device 3 is provided on the outer side of the middle part of the oil-immersing housing 21. A wire rope pressing oil-immersing component is provided inside the oil-immersing housing 21 corresponding to the grease heating device 3. A temperature sensor 4 connected to the inside of the oil-immersing housing 21 is provided on one side of the grease heating device 3, and a second wire rope guide wheel 5 is provided inside the end of the oil-immersing housing 21. A primary degreasing component is provided on the inner wall of the oil-immersing housing 21 between the second wire rope guide wheel 5 and the grease heating device 3. This invention utilizes the gravity of the grease itself to set up a wire rope oil-immersing area and a primary degreasing component, and controls the temperature of the grease through the grease heating device 3 and the temperature sensor 4. The grease heating device 3 can be a conventional form of heating, such as natural gas heating, electric heating, or coal heating, and the temperature of the heated grease is monitored by the temperature sensor 4 to ensure the oil immersion effect of the wire rope. On this basis, the wire rope pressing oil immersion component can be set to press down the wire rope to ensure that the wire rope can be effectively immersed in the grease. In addition, the primary degreasing component set at the above position can remove a large amount of grease. After removal, the grease returns to the wire rope oil immersion area by the slope of the oil immersion section housing 21 and the gravity of the grease itself, so as to realize the recycling and reuse of grease. In the above area, the wire rope passes through the upper part of the first wire rope guide wheel 2, the lower part of the wire rope pressing oil immersion component, the primary degreasing component, and the upper part of the second wire rope guide wheel 5.

[0034] Furthermore, the deburring guide unit includes a support plate 6 connected to the front end of the oil-immersed housing 21. A fixed frame 7 is provided at the outer end of the support plate 6. A third wire rope guide wheel 8 is provided on the side of the fixed frame 7 near the support plate 6. A brush 38 for deburring is provided on the side of the fixed frame 7 away from the support plate 6. Support rods 9 are provided on both sides of the middle part of the support plate 6. A movable shaft 10 is provided between the middle parts of the support rods 9. A channel steel 11 for guiding the wire rope is provided on the outside of the movable shaft 10. A handle 12 is provided on the upper surface of the channel steel 11. The deburring guide unit is located at the front end of the oil-immersing body 1. One of its purposes is to guide the wire rope to ensure it enters the oil-immersing body 1 smoothly. Its second purpose is to remove burrs from the wire rope to ensure it does not affect the service life of subsequent equipment. During use, it passes through the fixed frame 7, specifically positioned between the third wire rope guide wheel 8 and the brush 38. Then, it enters the oil-immersing housing 21 within the oil-immersing body 1 through the lower part of the channel steel 11. The channel steel 11 presses down on the upper part of the wire rope by its own weight, serving not only as a guide but also removing burrs from the upper part of the wire rope. When adjustment of the channel steel 11 is needed, it can be lifted using the handle 12.

[0035] Furthermore, the waste gas collection and treatment unit is installed on the oil-immersed housing 21 corresponding to the top of the second wire rope guide wheel 5. The waste gas collection and treatment unit includes a waste gas pipe 13 that communicates with the interior of the oil-immersed housing 21. The waste gas pipe 13 is connected to the inlet of the activated carbon storage tank 15 via an induced draft fan 14, and the outlet of the activated carbon storage tank 15 is connected to the gas exhaust pipe 16. Based on the principle of gas phase rise, this invention places the waste gas pipe 13 at the top of the end of the oil-immersed housing 21, and simultaneously activates the induced draft fan 14 to create a negative pressure near the inlet of the waste gas pipe 13, thereby achieving effective recovery and treatment of the waste gas.

[0036] Furthermore, the oil removal device includes an oil removal housing 17, which contains a primary oil removal component and a secondary oil removal component. The inlet end of the oil removal housing 17 is lower than its outlet end. The inlet end of the oil removal housing 17 is connected to the end of the downwardly extending connecting housing 22. An oil receiving groove 18 is provided on one side of the inlet end of the oil removal housing 17 at the connection point, and the bottom of the oil receiving groove 18 is connected to the oil receiving box 19. A downward-pressing wire rope guide is provided in the middle of the downwardly extending connecting housing 22. A fourth wire rope guide wheel 39 is provided at the outlet end of the oil removal housing 17. The oil removal housing 17 in this invention has an inclined structure with a lower inlet end and a higher outlet end. This inclined structure cooperates with the end of the downwardly extending connecting housing 22, so that its connection point is located at the lowest end of two adjacent devices. Based on this, the oil receiving groove 18 can realize that grease enters its interior under its own gravity and facilitates recycling. The downward-pressing wire rope guide described in this invention is adapted to the second wire rope guide wheel 5 mentioned above to guide the wire rope. It should be particularly noted that the oil-immersing body described in this invention has a wave-shaped structure with one end upward and the other downward. Specifically, the oil-immersing body includes an oil-immersing shell with a "V"-shaped front end and a rear end connecting shell integrally formed with it. In the above structural form, the middle part of the oil-immersing shell is the oil-immersing area of ​​the wire rope. Simultaneously, a primary degreasing component is provided at the rear middle position of the oil-immersing shell, which can remove most of the grease from the wire rope and utilize the oil... The grease is effectively recovered by gravity; a waste gas collection and treatment unit is provided at the rear of the oil-immersing section housing to collect and treat waste gas; the downward-extending connecting section housing 22 not only facilitates connection with the oil removal housing 17, but also reduces the overall height of the equipment, and lays the foundation for setting up the oil receiving tank 18; in addition, the grease dripping from the wire rope during operation of the downward-extending connecting section housing 22 can also be recovered; the present invention not only enables the quick use of the oil-immersed wire rope without polluting the environment, but also maximizes the recycling and reuse of grease, thereby saving oil immersion costs.

[0037] Furthermore, the primary degreasing component, the second-stage degreasing component, and the third-stage degreasing component have the same structure, including a lower degreasing plate 23 with a support plate 40 and an upper degreasing plate 24 with a bolt rod 20. The upper part of the bolt rod 20 passes through the corresponding oil-immersing housing and the degreasing housing 17. Height-adjusting nuts 25 are respectively attached to the bolt rod 20 on the outer side of the oil-immersing housing and the degreasing housing 17. The lower degreasing plate 23 in this invention is fixedly installed, serving not only as a degreasing unit but also as a guide; while the upper degreasing plate 24 is movable, allowing it to move up and down according to the size of the wire rope, specifically achieved through the height-adjusting nuts 25.

[0038] Furthermore, a lower degreasing groove 26 is provided at the top center of the lower degreasing plate 23, and an upper degreasing groove 27 is provided at the bottom center of the upper degreasing plate 24. Rubber wear-resistant layers 28 are respectively provided on the inner walls of the lower degreasing groove 26 and the upper degreasing groove 27. By providing the rubber wear-resistant layers 28, not only can grease be effectively removed, but the service life of the lower degreasing groove 26 and the upper degreasing groove 27 can also be improved, and the wire rope can be protected.

[0039] Furthermore, the upper degreasing plate 24 and the lower degreasing plate 23 are staggered, with the upper degreasing plate 24 located at the front and the lower degreasing plate 23 located at the rear. Preferably, the present invention adopts the configuration where the upper degreasing plate 24 is located at the front and the lower degreasing plate 23 at the rear. This structural configuration allows for the initial degreasing of the upper part of the wire rope, causing some grease to drip and be collected, while some grease is pushed to the lower part of the wire rope. Then, the lower degreasing plate 23 removes the grease, thereby improving the degreasing efficiency and effect. After the wire rope is immersed in oil, the primary degreasing unit, the second degreasing unit, and the above structural configuration work together to achieve thorough degreasing, ensuring that the wire rope can be used immediately after passing through the degreasing device without causing environmental pollution due to grease dripping.

[0040] Furthermore, the wire rope pressing and oil-immersing component includes a pressing block 29. A first screw 30 is provided at the top of the pressing block 29, with its upper part passing through the oil-immersing housing 21. A first adjusting nut 31 is provided at the top of the first screw 30. Slider blocks 32 are provided on both sides of the pressing block 29, with the ends of the sliders 32 respectively adapted to the grooves 34 in the corresponding guide blocks 33. The top of the guide blocks 33 is connected to the inner wall of the oil-immersing housing 21. In the above structure, the first adjusting nut 31 is used to adjust the height of the pressing block 29 to achieve different working conditions. To improve its structural stability, sliders 32 are provided on both sides of the pressing block 29, and the sliders 32 are adapted to the grooves 34. This not only facilitates guidance but also prevents displacement during prolonged pressing of the wire rope, thus avoiding defects that could affect the oil-immersing effect.

[0041] Furthermore, the downward-pressing wire rope guide includes a downward-pressing channel steel 35, with a second screw 36 at the top of the channel steel 35. The upper part of the second screw 36 passes through the downwardly extending connecting housing 22, and a second adjusting nut 37 is provided at the top of the second screw 36. In the above structure, the second adjusting nut 37 is used to adjust the height of the downward-pressing channel steel 35 to meet the purpose of use under different working conditions.

[0042] The present invention also provides an oil-immersion method for an oil-immersion device for crane wire ropes, comprising the following steps:

[0043] Step 1: The steel wire rope to be immersed in oil passes between the third steel wire rope guide wheel 8 and the brush 38. The brush 38 removes the burrs on the surface of the steel wire rope. Then, the steel wire rope to be immersed in oil is guided into the oil-immersing body 1 through the lower part of the channel steel 11. The brush 38 is a steel wool ball or a steel wire brush. The channel steel 11 is movably set with the movable shaft 10. The channel steel 11 presses down on the top of the steel wire rope to be immersed in oil by its own weight. It can be adjusted according to the diameter of the steel wire rope to be immersed in oil, and removes the burrs on the surface of the steel wire rope while achieving the guiding function.

[0044] Step 2: The steel wire rope to be immersed in oil enters the degreasing device through the upper part of the first steel wire rope guide wheel 2, the lower part of the steel wire rope pressing oil-immersing component, between the primary degreasing components, the upper part of the second steel wire rope guide wheel 5, and the lower pressing steel wire rope guide component. The steel wire rope to be immersed in oil is guided by the upper part of the first steel wire rope guide wheel 2 and pressed into the grease by the lower part of the steel wire rope pressing oil-immersing component. After immersion in oil, the steel wire rope continues to move forward and comes into contact with the rubber wear-resistant layer 28 on the inner wall of the lower degreasing tank 26 and the upper degreasing tank 27 for degreasing. Excess grease flows back into the corresponding grease tank at the upper part of the grease heating device 3 for continued use. The steel wire rope that has passed through the primary degreasing component enters the degreasing device under the guidance of the second steel wire rope guide wheel 5 and the lower pressing steel wire rope guide component. During this process, the dripping grease enters the oil receiving tank 18 along the inner wall of the downward extending connecting part housing 22 under the action of gravity.

[0045] Step 3: During the operation of Step 2 above, the grease heating device 3 continuously heats the grease in the grease tank. The flue gas generated by heating is adsorbed in the activated carbon storage tank 15 through the exhaust pipe 13 under the action of the induced draft fan 14, and then discharged through the gas exhaust pipe 16.

[0046] Step 4: The oil-soaked wire rope passes sequentially between the lower degreasing groove 26 and the upper degreasing groove 27 of the primary degreasing unit and between the lower degreasing groove 26 and the upper degreasing groove 27 of the secondary degreasing unit. The two degreasing units have limiting and guiding functions while removing oil, and finally the oil-soaked wire rope is connected to the subsequent power collection section through the fourth wire rope guide wheel 39.

[0047] Step 5: When the wire rope described in Steps 2 and 3 passes through the primary degreasing unit, the first degreasing unit, and the second degreasing unit, the wire rope first contacts the rubber wear-resistant layer 28 in the upper degreasing groove 27, so that the excess grease on the upper circumferential surface of the wire rope drips off and / or enters the lower circumferential surface of the wire rope under the combined action of gravity and the rubber wear-resistant layer 28. Then it contacts the rubber wear-resistant layer 28 in the lower degreasing groove 26, so that the excess grease on the lower circumferential surface of the wire rope drips off under the combined action of gravity and the rubber wear-resistant layer 28.

[0048] Step 6: The grease dripping from the wire rope after passing through the primary and secondary degreasing components in Step 3 enters the oil collecting trough 18 by gravity at the inlet end of the degreasing housing 17, which is lower than the outlet end of the degreasing housing 17. The grease in the oil collecting trough 18 eventually enters the oil collecting box 19 for recycling and reuse.

[0049] This invention is particularly applicable to crane wire ropes. As is well known, crane wire ropes are characterized by large diameter and long length. Due to frequent use and heavy loads, they require frequent maintenance. However, in actual maintenance, the large diameter of the crane wire rope prevents lubricating oil from penetrating its interior, resulting in poor maintenance effectiveness. Furthermore, the long length consumes a large amount of lubricating oil, and the large volume of the rope after oil immersion easily drips onto the ground, causing waste and environmental pollution. Conventional oil absorption and control methods also render the crane wire rope unusable for extended periods, affecting the normal operation of the crane. This invention improves the fluidity of the lubricating oil by heating it, allowing it to penetrate the wire rope and achieving a better maintenance effect. However, this heating increases the fluidity of the lubricating oil (leading to dripping) and generates exhaust gas that pollutes the environment. Therefore, this invention incorporates an exhaust gas pipe 13 at the upper part of the end of the oil immersion housing 21, using a negative pressure system. To prevent environmental pollution, this invention features a primary degreasing component in the inclined rear section of the oil-immersing housing 21 to remove most of the lubricating oil under gravity. Furthermore, considering the large diameter of the crane wire rope, a downwardly extending connecting housing 22 and a degreasing device are provided at the rear of the oil-immersing housing 21. This allows for multiple changes in the direction of the crane wire rope, and the use of the degreasing component under gravity to remove lubricating oil droplets, achieving effective lubricating oil recovery. Moreover, the invention utilizes structural designs for the primary, secondary, and tertiary degreasing components, such as adjusting the relative positions of the lower and upper degreasing plates 23 and 24, adjusting the height of the upper degreasing plate 24 with a height-adjusting nut 25, and a rubber wear-resistant layer 28, to thoroughly remove lubricating oil from the surface of the crane wire rope. This lays the foundation for maximizing the recycling and reuse of lubricating oil, preventing oil droplet pollution, and facilitating the rapid use of the wire rope.

[0050] To explain the present invention in more detail, the invention will now be further described with reference to embodiments. Specific embodiments are as follows:

[0053] An oil-immersion method for a crane wire rope oil-immersion device includes the following steps:

[0054] Step 1: The steel wire rope to be immersed in oil passes between the third steel wire rope guide wheel 8 and the brush 38. The brush 38 removes the burrs on the surface of the steel wire rope. Then, the steel wire rope to be immersed in oil is guided into the oil-immersing body 1 through the lower part of the channel steel 11. The brush 38 is a steel wool ball. The channel steel 11 is movably set with the movable shaft 10. The channel steel 11 presses down on the top of the steel wire rope to be immersed in oil by its own weight. It can be adjusted according to the diameter of the steel wire rope to be immersed in oil, and removes the burrs on the surface of the steel wire rope while achieving the guiding function.

[0055] Step 2: The steel wire rope to be immersed in oil enters the degreasing device through the upper part of the first steel wire rope guide wheel 2, the lower part of the steel wire rope pressing oil-immersing component, between the primary degreasing components, the upper part of the second steel wire rope guide wheel 5, and the lower pressing steel wire rope guide component. The steel wire rope to be immersed in oil is guided by the upper part of the first steel wire rope guide wheel 2 and pressed into the grease by the lower part of the steel wire rope pressing oil-immersing component. After immersion in oil, the steel wire rope continues to move forward and comes into contact with the rubber wear-resistant layer 28 on the inner wall of the lower degreasing tank 26 and the upper degreasing tank 27 for degreasing. Excess grease flows back into the corresponding grease tank at the upper part of the grease heating device 3 for continued use. The steel wire rope that has passed through the primary degreasing component enters the degreasing device under the guidance of the second steel wire rope guide wheel 5 and the lower pressing steel wire rope guide component. During this process, the dripping grease enters the oil receiving tank 18 along the inner wall of the downward extending connecting part housing 22 under the action of gravity.

[0056] Step 3: During the operation of Step 2 above, the grease heating device 3 continuously heats the grease in the grease tank. The flue gas generated by heating is adsorbed in the activated carbon storage tank 15 through the exhaust pipe 13 under the action of the induced draft fan 14, and then discharged through the gas exhaust pipe 16.

[0057] Step 4: The oil-soaked wire rope passes sequentially between the lower degreasing groove 26 and the upper degreasing groove 27 of the primary degreasing unit and between the lower degreasing groove 26 and the upper degreasing groove 27 of the secondary degreasing unit. The two degreasing units have limiting and guiding functions while removing oil, and finally the oil-soaked wire rope is connected to the subsequent power collection section through the fourth wire rope guide wheel 39.

[0058] Step 5: When the wire rope described in Steps 2 and 3 passes through the primary degreasing unit, the first degreasing unit, and the second degreasing unit, the wire rope first contacts the rubber wear-resistant layer 28 in the upper degreasing groove 27, so that the excess grease on the upper circumferential surface of the wire rope drips off and / or enters the lower circumferential surface of the wire rope under the combined action of gravity and the rubber wear-resistant layer 28. Then it contacts the rubber wear-resistant layer 28 in the lower degreasing groove 26, so that the excess grease on the lower circumferential surface of the wire rope drips off under the combined action of gravity and the rubber wear-resistant layer 28.

[0059] Step 6: The grease dripping from the wire rope after passing through the primary and secondary degreasing components in Step 3 enters the oil collecting trough 18 by gravity at the inlet end of the degreasing housing 17, which is lower than the outlet end of the degreasing housing 17. The grease in the oil collecting trough 18 eventually enters the oil collecting box 19 for recycling and reuse.
