Description

Technical Field

[0001] This invention belongs to the technical field of wire rope grease coating devices, and particularly relates to an automatic wire rope grease coating device. Background Technology

[0002] The automatic grease coating device for wire ropes is a specialized piece of equipment that uses an automated mechanical structure and intelligent control unit to precisely and continuously apply grease to the surface and interior (interstrand gaps, rope core) of wire ropes. Its function is to ensure that the wire rope maintains a uniform and sufficient oil film protection during operation, ultimately extending the service life of the wire rope, reducing maintenance costs, and minimizing safety risks associated with manual intervention.

[0003] Existing automatic grease coating devices for wire ropes mainly refer to grease applicators. In use, the nozzle of the applicator is attached to the wire rope, and grease is applied to one side of the wire rope surface through a nozzle or brush inside the nozzle. However, in actual use, due to the gap between the nozzle and the wire rope, and the grooves on the wire rope surface, existing nozzles struggle to evenly coat the grease onto the wire rope surface. Furthermore, the brush bristles are not easily and evenly wetted by grease, and when grease adheres to the bristles, they become sticky, further affecting the grease application effect on the wire rope surface.

[0004] Therefore, it is necessary to invent an automatic grease coating device for steel wire ropes to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an automatic wire rope grease coating device to solve the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic grease coating device for wire ropes includes an oiler body. An oiling device is connected to the oiler via a delivery pipe. The oiling device includes two semi-cylindrical clamping plates, symmetrically hinged together. A semi-circular first oil inlet pipe and a second oil inlet pipe are disposed between opposite sides of the two clamping plates. The first and second oil inlet pipes are rotatably mounted on opposite sides of the two clamping plates. An arc-shaped plate is slidably mounted on the outer arc surface inside the first oil inlet pipe, and a connecting pipe is inserted through the outer arc surface of the arc plate. A through-hole is formed on the outer arc surface of the first oil inlet pipe. The strip-shaped through hole allows the connecting pipe to pass through and be inserted into the corresponding clamping plate. The connecting pipe is also connected to the delivery pipe. Both ends of the first oil inlet pipe are connected to inserts. Both ends of the second oil inlet pipe have insertion holes that match the inserts. A spreading component is provided on the same side of both the first and second oil inlet pipes to spread lubricating grease onto the wire rope. Teeth are evenly distributed on the outer arc surface of the second oil inlet pipe. A first driving component is installed on the clamping plate connected to the second oil inlet pipe to cooperate with the teeth on the second oil inlet pipe to drive the second oil inlet pipe to rotate back and forth periodically.

[0008] Furthermore, the spreading assembly includes an oil spreading tube, a movable tube, a telescopic rod, and a clamping spring. The oil spreading tube is vertically connected to the side of the first oil inlet tube or the second oil inlet tube, and the oil spreading tube communicates with the first oil inlet tube or the second oil inlet tube. The movable tube is slidably inserted into the side of the oil spreading tube near the axis of the clamping plate. The side of the movable tube near the axis of the clamping plate has an arc surface design, and several oil outlet holes are evenly opened on the arc surface of the movable tube. There are multiple telescopic rods, which are vertically connected inside the oil spreading tube and between the movable tube. The clamping spring is sleeved on the telescopic rod, and the two ends of the clamping spring are fixedly connected to the telescopic rod near the two ends. The clamping spring is used to press the movable tube against the surface of the wire rope.

[0009] Furthermore, the first drive assembly includes a first motor and a first gear. The first motor is mounted on the side of the clamping plate away from the first oil inlet pipe. The first gear is driven and mounted on the output shaft of the first motor. The clamping plate has a first connecting hole through it at the position directly opposite the first gear. The first gear passes through the first connecting hole and meshes with the teeth on the first oil inlet pipe. The maximum angle at which the first gear drives the first oil inlet pipe to rotate matches the included angle between two adjacent movable pipes.

[0010] Furthermore, a cleaning device for cleaning the surface of the wire rope is provided on the side of the first oil inlet pipe away from the oiling pipe. The cleaning device includes a first toothed ring, a second toothed ring, a spiral cleaning plate, bristles, and a second drive assembly. The first and second toothed rings are both semi-circular rings and can be spliced ​​together to form a complete ring. Grooves matching their outer length are formed on the outer arc surfaces of both the first and second toothed rings, and the teeth of the first and second toothed rings are evenly distributed in the grooves. The first and second toothed rings are rotatably mounted on the opposite side of the two clamping plates, and both ends of the first toothed ring are fixed. The device is connected to a first insert block. Both ends of the second toothed ring are provided with first slots that match the first insert block. There are multiple spiral cleaning plates, and the axis of the spiral cleaning plate coincides with the axis of the first toothed ring. The multiple spiral cleaning plates are evenly fixedly connected to the first toothed ring and the second toothed ring on the side away from the first oil inlet pipe. The position of the clamping plate opposite the spiral cleaning plate is hollow. The bristles are evenly fixedly connected to the side of the spiral cleaning plate near its axis, and the free end of the bristles is closer to the axis of the clamping plate than the movable tube. The second drive assembly is installed at the position where the clamping plate and the first toothed ring are opposite, and is used to drive the first toothed ring to rotate.

[0011] Furthermore, the second drive assembly includes a second motor and a second gear. The second motor is mounted on the side of the card plate away from the first oil inlet pipe. The second gear is driven and mounted on the output shaft of the second motor. A second connecting hole is provided through the card plate at the position directly opposite the second gear. The second gear passes through the second connecting hole and meshes with the teeth on the first gear ring or the second gear ring.

[0012] Furthermore, there are multiple oil-applying tubes, which are connected at equal intervals to the side of the first and second oil inlet tubes away from the cleaning component. The ends of the multiple oil-applying tubes away from the first oil inlet tube are fixedly connected with a semi-circular first reinforcing ring and a second reinforcing ring. The first and second reinforcing rings are respectively rotatably installed between the two opposite sides of the two clamping plates, and the two can be spliced ​​into a complete ring. The two ends of the first reinforcing ring are fixedly connected with second inserts, and the two ends of the second reinforcing ring are provided with second slots that match the second inserts. Reinforcing rods are vertically fixedly connected between the first reinforcing ring and the second oil inlet tube, and between the second reinforcing ring and the first oil inlet tube.

[0013] Furthermore, multiple spring pieces are fixedly connected to the side of the first and second reinforcing rings away from the oiling tube. The free ends of the spring pieces are inclined towards the direction of the card plate axis. A striking ball is fixedly connected to the free ends of the spring pieces. The striking ball is closer to the card plate axis than the movable tube.

[0014] Furthermore, both the first motor and the second motor are provided with protective covers on their outer sides. The protective covers are detachably connected to the card plate, and both the first gear and the second gear are located inside the protective covers.

[0015] Furthermore, multiple scraper strips matching the length of the movable tube are uniformly fixedly connected to the side of the movable tube near the axis of the card plate, and the scraper strips are made of wear-resistant rubber.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. The present invention, by providing a grease spreading component, allows the movable tube to remain in close contact with the surface of the wire rope under the action of the compression spring when the card plate is installed on the wire rope. Thus, when the lubricating grease is squeezed out from the movable tube, it can firmly adhere to the surface of the wire rope under pressure. Furthermore, since there are grooves on the surface of the wire rope, when the lubricating grease is squeezed onto the surface of the wire rope, it can also better penetrate into the grooves on the surface of the wire rope under pressure, thereby improving the effect of grease spreading and maintenance on the wire rope.

[0018] 2. The present invention includes a cleaning device. While the movable tube is applying oil to the surface of the wire rope, the second motor can drive the first and second gear rings to rotate through the second gear. During this process, the surface of the wire rope is cleaned by the bristles on the spiral cleaning plate, thereby preventing dust adhering to the surface of the wire rope from entering the area where the movable tube is located. This prevents the adhesion between the lubricating grease and the surface of the wire rope from being reduced due to dust on the surface of the wire rope, and improves the oiling and maintenance effect of the wire rope.

[0019] 3. The present invention incorporates a striking ball. Since there are grooves on the surface of the wire rope, the striking ball can generate vibration as it moves along the surface of the wire rope. This vibration allows the grease applied to the surface of the wire rope to penetrate into the grooves of the wire rope, thereby performing a deeper oiling and maintenance operation on the wire rope and improving the oiling and maintenance effect.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] This invention provides, for example Figures 1 to 10An automatic grease coating device for wire ropes is shown, comprising an oiler body 1, an oiling device connected to the oiler via a delivery pipe 2, and an oiling device including two semi-cylindrical clamping plates 3, which are symmetrically hinged together. A latch for locking the two clamping plates 3 is provided on the side away from the hinge. A semi-circular first oil inlet pipe 4 and a second oil inlet pipe 5 are provided between the opposite sides of the two clamping plates 3. The first oil inlet pipe 4 and the second oil inlet pipe 5 are respectively rotatably mounted on the opposite sides of the two clamping plates 3. An arc-shaped plate 10 is slidably mounted on the outer arc surface inside the first oil inlet pipe 4, and a connecting pipe 6 is inserted through the outer arc surface of the arc plate 10. A strip-shaped through hole 7 is opened through the outer arc surface of the oil inlet pipe 4. The connecting pipe 6 passes through the through hole 7 and is inserted into the corresponding clamping plate 3. The connecting pipe 6 is connected to the conveying pipe 2. Both ends of the first oil inlet pipe 4 are connected to the insertion pipe 8. Both ends of the second oil inlet pipe 5 are opened with insertion holes 9 that match the insertion pipe 8. The first oil inlet pipe 4 and the second oil inlet pipe 5 are both provided with a spreading component on the same side for spreading lubricating grease on the wire rope. The outer arc surface of the second oil inlet pipe 5 is evenly provided with teeth. The clamping plate 3 connected to the second oil inlet pipe 5 is equipped with a first driving component for cooperating with the teeth on the second oil inlet pipe 5 to drive the second oil inlet pipe 5 to rotate back and forth periodically.

[0033] The oiling assembly includes an oiling pipe 11, a movable pipe 12, a telescopic rod 13, and a clamping spring 14. The oiling pipe 11 is vertically connected to the side of the first oil inlet pipe 4 or the second oil inlet pipe 5, and the oiling pipe 11 is connected to the first oil inlet pipe 4 or the second oil inlet pipe 5. The movable pipe 12 is slidably inserted into the side of the oiling pipe 11 near the axis of the clamping plate 3. The side of the movable pipe 12 near the axis of the clamping plate 3 is designed with an arc surface, and several oil outlet holes are evenly opened on the arc surface of the movable pipe 12. There are multiple telescopic rods 13, which are vertically connected inside the oiling pipe 11 and between the movable pipe 12. The clamping spring 14 is sleeved on the telescopic rod 13, and the two ends of the clamping spring 14 are fixedly connected to the telescopic rod 13 near the two ends. The clamping spring 14 is used to press the movable pipe 12 against the surface of the wire rope.

[0034] The first drive assembly includes a first motor 15 and a first gear 16. The first motor 15 is mounted on the side of the clamping plate 3 away from the first oil inlet pipe 4. The first gear 16 is driven and mounted on the output shaft of the first motor 15. A first connecting hole is provided through the clamping plate 3 at the position directly opposite the first gear 16. The first gear 16 passes through the first connecting hole and meshes with the teeth on the first oil inlet pipe 4. The maximum angle at which the first gear 16 drives the first oil inlet pipe 4 to rotate matches the included angle between two adjacent movable pipes 12.

[0035] By incorporating a spreading component, when applying oil to the wire rope, the buckle is first opened, then the wire rope is placed on one of the clamping plates 3, and then the other clamping plate 3 is moved to make the two clamping plates 3 snap together. The two clamping plates 3 are then locked by the buckle. During the locking process, as the two clamping plates 3 approach each other, the movable tube 12 can be pressed against the surface of the wire rope by the clamping plate 3. As the two clamping plates 3 continue to approach each other, the reaction force of the wire rope on the movable tube 12 can gradually compress the telescopic rod 13 and the compression spring 14. When the two clamping plates 3 are fully snapped together, the movable tube 12 can be pressed against the surface of the wire rope by the pressure of the compression spring 14, and the insertion tube 8 on the first oil inlet pipe 4 can also be inserted into the insertion hole 9 of the second oil inlet pipe 5, thereby realizing the connection operation of the first oil inlet pipe 4 and the second oil inlet pipe 5.

[0036] After the wire rope is installed, with the activation of the oiler body 1, the lubricating grease can be delivered to the first oil inlet pipe 4 through the delivery pipe 2 under the action of the oiler body 1. Then, the grease in the first oil inlet pipe 4 can enter the second oil inlet pipe 5 and each oiling pipe 11 respectively. Then, the lubricating grease entering the oiling pipe 11 can be sprayed onto the surface of the wire rope through the oil outlet on the movable pipe 12. Since the movable pipe 12 is in close contact with the surface of the wire rope, when the lubricating grease is squeezed out from the movable pipe 12, the lubricating grease can firmly adhere to the surface of the wire rope under pressure. Therefore, compared with the existing nozzle or brush 20, the gap between the nozzle or brush 20 and the surface of the wire rope is reduced, so that the lubricating grease can be "pressed" onto the surface of the wire rope under pressure. Furthermore, since there are grooves on the surface of the wire rope, when the lubricating grease is squeezed onto the surface of the wire rope, the lubricating grease can also better penetrate into the grooves on the surface of the wire rope under pressure, thereby improving the effect of oiling and maintenance of the wire rope.

[0037] Subsequently, with the start of the first motor 15, the first motor 15 can drive the first oil inlet pipe 4 and the second oil inlet pipe 5 to rotate back and forth within a certain range through the engagement of the teeth on the first gear 16 and the second oil inlet pipe 5. During this process, the arc plate 10 can move back and forth inside the first oil inlet pipe 4, while the movable pipe 12 can scrape back and forth on the surface of the wire rope under the drive of the first oil inlet pipe 4 and the second oil inlet pipe 5, thereby evenly applying the lubricating grease to the surface of the wire rope.

[0038] As shown in the figure, a cleaning device for cleaning the surface of the wire rope is provided on the side of the first oil inlet pipe 4 away from the oiling pipe 11. The cleaning device includes a first toothed ring 17, a second toothed ring 18, a spiral cleaning plate 19, bristles 20, and a second drive assembly. The first toothed ring 17 and the second toothed ring 18 are both semi-circular rings and can be spliced ​​together to form a complete ring. The outer arc surfaces of the first toothed ring 17 and the second toothed ring 18 are each provided with a groove matching their outer length, and the teeth of the first toothed ring 17 and the second toothed ring 18 are evenly arranged in the grooves. The first toothed ring 17 and the second toothed ring 18 are respectively rotatably mounted on the opposite side of the two clamping plates 3. Both ends of the first toothed ring 17 are fixedly connected to the second drive assembly. The first insert 21 and the second toothed ring 18 are provided with first slots 22 at both ends that match the first insert 21. There are multiple spiral cleaning plates 19, and the axis of the spiral cleaning plate 19 coincides with the axis of the first toothed ring 17. Multiple spiral cleaning plates 19 are evenly fixedly connected to the first toothed ring 17 and the second toothed ring 18 on the side away from the first oil inlet pipe 4. The position of the clamping plate 3 opposite to the spiral cleaning plate 19 is hollow. The bristles 20 are evenly fixedly connected to the side of the spiral cleaning plate 19 near its axis, and the free end of the bristles 20 is closer to the axis of the clamping plate 3 than the movable tube 12. The second drive assembly is installed at the position of the clamping plate 3 opposite to the first toothed ring 17 to drive the first toothed ring 17 to rotate.

[0039] The second drive assembly includes a second motor 23 and a second gear 24. The second motor 23 is mounted on the side of the card plate 3 away from the first oil inlet pipe 4. The second gear 24 is driven on the output shaft of the second motor 23. A second connecting hole is provided through the card plate 3 at the position directly opposite the second gear 24. The second gear 24 passes through the second connecting hole and meshes with the teeth on the first gear ring 17 or the second gear ring 18.

[0040] With the cleaning device in place, when the two clips 3 are fastened together by the buckle, the first insert 21 on the first toothed ring 17 can be inserted into the first slot 22 on the second toothed ring 18, thereby realizing the splicing operation of the first toothed ring 17 and the second toothed ring 18. At this time, multiple spiral cleaning plates 19 can be evenly distributed in a ring around the wire rope, and the bristles 20 on the spiral cleaning plates 19 can keep in contact with the surface of the wire rope.

[0041] While the movable tube 12 is applying oil to the surface of the wire rope, the second motor 23 can drive the first gear ring 17 and the second gear ring 18 to rotate through the second gear 24. As the wire rope continuously passes between the two clamping plates 3, the first gear ring 17 and the second gear ring 18 can drive multiple spiral cleaning plates 19 to rotate around the surface of the wire rope. During this process, the surface of the wire rope is cleaned by the bristles 20 on the spiral cleaning plates 19, thereby preventing dust adhering to the surface of the wire rope from entering the area where the movable tube 12 is located. This prevents the adhesion between the lubricating grease and the surface of the wire rope from being reduced due to dust on the surface of the wire rope, and improves the oiling and maintenance effect of the wire rope.

[0042] During the cleaning process of the wire rope surface by the brush 20, the spiral cleaning plate 19 can also generate wind during rotation, thereby blowing the cleaned dust out of the card plate 3 through the hollow area on the card plate 3, preventing the dust from accumulating in the inner area of ​​the card plate 3.

[0043] As shown in the figure, there are multiple oiling pipes 11. The multiple oiling pipes 11 are connected at equal intervals to the side of the first oil inlet pipe 4 and the second oil inlet pipe 5 away from the cleaning component. The ends of the multiple oiling pipes 11 away from the first oil inlet pipe 4 are fixedly connected with a semi-circular first reinforcing ring 25 and a second reinforcing ring 26. The first reinforcing ring 25 and the second reinforcing ring 26 are respectively rotatably installed between the two opposite sides of the two clamping plates 3, and the two can be spliced ​​into a complete ring. The two ends of the first reinforcing ring 25 are fixedly connected with second inserts 27. The two ends of the second reinforcing ring 26 are provided with second slots 28 that match the second inserts 27. The first reinforcing ring 25 and the second oil inlet pipe 5 and the second reinforcing ring 26 and the first oil inlet pipe 4 are vertically fixedly connected with reinforcing rods 29.

[0044] By providing a first reinforcing ring 25 and a second reinforcing ring 26, when the two clamping plates 3 are fastened together by the buckle, the second inserts 27 at both ends of the first reinforcing ring 25 can be connected with the second slots 28 on the second reinforcing ring 26, thereby realizing the connection operation of the first reinforcing ring 25 and the second reinforcing ring 26. When the first oil inlet pipe 4 and the second oil inlet pipe 5 drive the oiling pipe 11 to rotate back and forth under the action of the first motor 15, the first reinforcing ring 25 and the second reinforcing ring 26 can also rotate together. The first reinforcing ring 25 and the second reinforcing ring 26 can cooperate with the first oil inlet pipe 4 and the second oil inlet pipe 5 to limit the two ends of the oiling pipe 11 during the rotation of the oiling pipe 11, so as to prevent the end of the oiling pipe 11 away from the first oil inlet pipe 4 from being bent and damaged due to lack of support.

[0045] As shown in the figure, multiple spring pieces 30 are fixedly connected to the side of the first reinforcing ring 25 and the second reinforcing ring 26 away from the oiling tube 11. The free end of the spring piece 30 is inclined towards the axis of the card plate 3. A striking ball 31 is fixedly connected to the free end of the spring piece 30. The striking ball 31 is closer to the axis of the card plate 3 than the movable tube 12.

[0046] Because of the grooves on the surface of the wire rope, lubricating grease is difficult to penetrate into these grooves during the oiling process, resulting in insufficient maintenance. To address this, a striking ball 31 is installed. When the two clamping plates 3 are fastened to the wire rope, the striking ball 31 adheres tightly to the surface of the wire rope under the elastic force of the spring plate 30. As the first reinforcing ring 25 and the second reinforcing ring 26 rotate back and forth under the influence of the first oil inlet pipe 4 and the second oil inlet pipe 5, the striking ball 31 slides along the surface of the wire rope. Because of the grooves on the wire rope surface, the striking ball 31 vibrates as it moves along the surface, allowing the grease applied to the wire rope surface to penetrate into the grooves under the vibration. This results in a deeper oiling and maintenance operation, improving the effectiveness of the wire rope's oiling and maintenance.

[0047] As shown in the figure, a protective cover 32 is provided on the outside of the first motor 15 and the second motor 23. The protective cover 32 is detachably connected to the card plate 3, and the first gear 16 and the second gear 24 are both located inside the protective cover 32.

[0048] The protective cover 32 can protect the first motor 15, the second motor 23, the first gear 16 and the second gear 24, and prevent dust in the outside air from adhering to the first gear 16 or the second gear 24.

[0049] As shown in the figure, multiple scraper strips 33 that match the length of the movable tube 12 are evenly fixedly connected to one side of the movable tube 12 near the axis of the card plate 3, and the scraper strips 33 are made of wear-resistant rubber.

[0050] By providing a scraper 33 on the movable tube 12, when the movable tube 12 is in contact with the surface of the wire rope for oiling, the softer scraper 33 can adhere more tightly to the surface of the wire rope under the action of the compression spring 14. As the movable tube 12 scrapes against the surface of the wire rope, the scraper 33 can apply the grease sprayed from the movable tube 12 to the surface of the wire rope more evenly.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
