Description
Technical Field
[0001] This invention relates to the field of wire rope maintenance technology, specifically to a wire rope decontamination and lubrication system. Background Technology
[0002] Wire ropes, as core structural components in the industrial field, come in a wide variety of types, mainly classified by the number of strands, diameter, and lay angle. They are widely used in hoists, cranes, elevators, and aerial ropeways. Over prolonged use, a thick layer of sludge easily accumulates on the surface of wire ropes, making problems such as deformation, broken wires, fatigue, and corrosion difficult to detect. This significantly reduces the reliability of the wire rope, greatly impacting its service life and construction safety. Therefore, regular cleaning and maintenance of lifting wire ropes is essential.
[0003] Wire rope cleaning and maintenance includes two steps: wire rope decontamination and wire rope oiling. These two steps are usually performed separately. Performing wire rope decontamination and oiling simultaneously would help reduce processing steps. Furthermore, existing wire rope decontamination and oiling devices have the following shortcomings:
[0004] Existing methods for cleaning steel wire ropes mainly fall into two categories: manual hand-held wire brushing and machine-rotated wire brushing. Manual hand-held wire brushing for cleaning oil stains on steel wire ropes is dangerous and labor-intensive. Machine-rotated wire brushing is cumbersome and costly, and may even require disassembling the steel wire rope for cleaning. Furthermore, ordinary wire brushes are ineffective at removing dirt from the crevices of steel wire ropes.
[0005] Existing oiling devices operate under normal pressure, where the oil only penetrates the surface of the wire rope and cannot reach its interior, resulting in mediocre oiling effectiveness. Furthermore, existing oiling devices are generally designed for wire ropes of fixed diameters and cannot accommodate wire ropes of different diameters. Therefore, it is necessary to design a wire rope decontamination and lubrication system. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention provides a wire rope decontamination and lubrication system.
[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:
[0008] A wire rope decontamination and lubrication system, characterized in that it includes a lubricating oiling device and a decontamination device arranged front and rear in the forward direction of the wire rope;
[0009] The decontamination device includes a decontaminator and an axial limiter;
[0010] The axial limiter is located on one side of the wire rope's direction of movement. The axial limiter is used to restrict the cleaning device from moving axially in the direction of the wire rope's movement when the wire rope is moving. The cleaning device includes a diameter changing mechanism and a cleaning knife.
[0011] The diameter-changing mechanism includes a diameter-changing block, a turntable, a fixed plate, a positioning shell, and a rotating block. Several diameter-changing blocks are evenly distributed circumferentially between the turntable and the fixed plate, the number of which depends on the number of wire rope strands. The turntable has a first track groove evenly distributed circumferentially, and the fixed plate has a second track groove evenly distributed circumferentially. The upper and lower surfaces of the diameter-changing block are slidably mounted in the corresponding track grooves of the fixed plate and the turntable via bosses. One end of the diameter-changing block has an open slot, within which a rotating block is rotatably mounted. One end of the rotating block has a groove, in which a cleaning knife is elastically mounted. The positioning shell is located outside the turntable and the fixed plate, used to limit the relative position of the turntable and the fixed plate. The positioning shell is fixedly connected to the fixed plate, and its connection to the turntable is adjustable circumferentially.
[0012] The oiling device includes a housing, a bushing disposed inside the housing, and sealing sleeves fitted at both ends of the housing. A sealed channel for a steel wire rope to pass through is formed between the bushing and the sealing sleeve. The bushing has an oil inlet and an oil return outlet on both sides.
[0013] The housing consists of two semi-circular housings, hinged on one side and connected to a locking assembly and a handle on the other side. One semi-circular housing is a return oil housing with a return oil passage corresponding to the bushing's return oil port and connected to the housing's return oil port. The other semi-circular housing is an injection oil housing. The injection oil housing has a pressurization chamber, a motor compartment, and a cover on its side. The pressurization chamber contains a pressurization screw, and the motor compartment contains a motor connected to the pressurization screw. One end of the cover is hinged to the injection oil housing, and the other end of the cover is sealed and fixed to the injection oil housing with screws.

The cover has an oil injection port, and the pressurization chamber has an oil inlet passage corresponding to the bushing's oil inlet.
[0014] Furthermore, one side of the variable diameter block is provided with a cylindrical boss that mates with the first track groove, and the other side of the variable diameter block is provided with a straight groove boss that mates with the second track groove. The cylindrical boss is provided with a first threaded hole, and the straight groove boss is provided with two second threaded holes. The cylindrical boss and the straight groove boss are respectively connected to the corresponding threaded holes by screws, so that the movement of the boss is restricted in the track groove.
[0015] Furthermore, the cleaning knife includes a blade body, a blade holder, an arc-shaped contact surface, and a bottom edge. The blade body has a blade holder on one side and arc-shaped contact surfaces that contact the surfaces of two adjacent steel wire ropes on both sides of the other side. The two arc-shaped contact surfaces transition into a bottom edge in the middle. The bottom edge has a certain slope, and the slope of the bottom edge is consistent with the twist angle of the steel wire rope and corresponds to the gap between the two steel wire ropes.
[0016] Furthermore, steel ball grooves are provided on both sides of the groove. The tool holder is a cuboid structure with a circular through hole extending along its length. A first compression spring is provided in the circular through hole, and steel balls are provided at both ends of the first compression spring. The first compression spring is always in a compressed state, and the steel balls are in a semi-exposed state. The tool holder is installed in the groove through the cooperation of the steel balls and the steel ball grooves.
[0017] Furthermore, a pressure sensor is provided on the bottom wall of the groove, and a second compression spring is provided between the pressure sensor and the blade holder. One end of the second compression spring is fixedly connected to the pressure sensor. The pressure sensor is used to detect the pressure value of the second compression spring and provide pressure value data to external devices, thereby detecting the preload force of the cleaning blade in contact with the wire rope.
[0018] Furthermore, the turntable, the fixed plate, and the positioning shell are all detachable structures in two halves. The two halves of the turntable are connected by a first bolt, and the two halves of the fixed plate and the positioning shell are fixedly connected by a second bolt.
[0019] The left and right halves of the turntable are each equipped with a handle, and the handles are equipped with variable diameter positioning holes; the left and right halves of the positioning housing are each equipped with an angle adjustment plate, and the angle adjustment plate is evenly provided with several angle holes with the turntable axis as the center. The positioning housing and the turntable are connected by inserting pins into the variable diameter positioning holes and the corresponding angle holes.
[0020] Furthermore, the two halves of the positioning housing are respectively provided with a positioning shoulder that matches the turntable, a first clearance groove for the handle to rotate and make room, and a second clearance groove for the connecting part of the left and right halves of the turntable to rotate and make room.
[0021] Furthermore, the axial limiter includes a limiter housing, a guide sleeve, and lifting rings. The limiter housing is designed as a cube, with guide sleeves rotatably mounted at both ends. Both the limiter housing and the guide sleeves have through holes at their axial positions that match the outer diameter of the wire rope. Multiple lifting rings are provided on the outer wall of the limiter housing. Both the limiter housing and the guide sleeves are designed as two-half structures, and the two halves of the limiter housing are fixedly connected by a third bolt.
[0022] Furthermore, the sealing sleeve is composed of two sealing sleeve halves. The interior between the two sealing sleeve halves has multiple gradually decreasing lubricating oil sealing grooves and sponge sealing grooves formed from the inside to the outside. A lubricating oil sealing ring is provided in the lubricating oil sealing groove, and a sponge sealing ring is provided in the sponge sealing groove. Both the lubricating oil sealing ring and the sponge sealing ring are annular structures formed by two semi-rings joined together. The outer surface of the two sealing sleeve halves has a semi-circular groove, and the two sealing sleeve halves are fixed to each other by clamps matching the semi-circular grooves. The bushing is composed of two half-bushings, namely an oil filling half-bushing and an oil return half-bushing, which are respectively nested in two semi-circular shells. Multiple sets of annular oil grooves are formed at both ends between the two half-bushings. Hinged ears are provided on the middle sides of one side of each of the two semi-circular shells, and the corresponding hinged ears are hinged together by hinge bolts.
[0023] Furthermore, the handle consists of two half-handles respectively mounted on two housings. The locking assembly includes a locking block, a fisheye screw, and a wing nut. Locking blocks are respectively provided at both ends of the two semi-circular housings near the corresponding half-handles. The fisheye end of the fisheye screw is rotatably positioned between the locking block and the half-handle on the oil return housing. The screw end of the fisheye screw is provided with a wing nut, which locks the corresponding half-handle and the locking block, thus fixing the two semi-circular housings into a complete structure. Positioning ears are provided radially symmetrically at both ends of the housings, and positioning ear holes are provided on the positioning ears. The two semi-circular housings are respectively provided with housing sealing oil grooves, and sealing gaskets are respectively provided in the housing sealing oil grooves.
[0024] Beneficial effects of this invention:
[0025] 1. This invention is small in size, low in cost, and adaptable to the cleaning and maintenance of steel wire ropes of various diameters. It can work in confined spaces and can achieve online cleaning and oiling of steel wire ropes without disassembling them, thus improving work efficiency.
[0026] 2. The variable diameter mechanism in this invention adopts a modular design, which can achieve a stepless variable diameter effect with high space utilization. The same decontaminator can adapt to wire ropes with the same number of strands but different diameters, and the number of variable diameter blocks can be changed so that it can also adapt to wire ropes with different numbers of strands.
[0027] 3. The present invention provides a first compression spring, a steel ball, and a steel ball groove inside the cleaning blade and the rotating block to make the cleaning blade part easy to disassemble and replace.
[0028] 4. By setting a second compression spring and a pressure sensor, the pressure data can be observed through external equipment. The rotation angle of the turntable can be adjusted to adjust the elasticity of the second compression spring, thereby indirectly adjusting the preload of the cleaning blade. This ensures that the cleaning blade is always in elastic contact with the wire rope, guaranteeing the cleaning effect. During operation, the wear of the cleaning blade can be detected, and replacement is required. At the same time, the second compression spring can also allow the cleaning blade to extend and retract relative to the wire rope to a certain extent, avoiding rigid contact with the wire rope as much as possible and preventing scratches on the surface of the wire rope.
[0029] 5. In this invention, the lubricating device utilizes a screw pressurization mechanism to improve the fluidity and application pressure of the lubricating oil, allowing it to be sprayed more evenly onto the surface of the wire rope, achieving uniform oil immersion and penetration into the wire rope. Simultaneously, the motor speed can be adjusted to control the internal pressure. Furthermore, replaceable sealing sleeves are installed at both ends of the device, allowing users to select the appropriate model for better sealing conditions. The internal bushings can also be replaced with suitable sizes for different sized wire ropes, improving the device's applicability. The overall internal space achieves pressure balance, fluid circulation, and grease replenishment, ensuring the device's safety and sealing performance. Attached Figure Description

[0053] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.
[0054] Example 1: See Figure 1 As shown, a wire rope decontamination and lubrication system includes a lubricating device and a decontamination device arranged front and rear in the forward direction of the wire rope; the decontamination device includes a decontaminator and an axial limiter; wherein, the axial limiter is located on one side in the direction of wire rope movement, and the axial limiter is used to restrict the decontaminator from moving axially in the direction of wire rope movement when the wire rope moves.
[0055] For details on the structure of the stain remover, please refer to [link / reference]. Figure 3 — Figure 14 As shown, the decontaminator includes a diameter-changing mechanism and a decontamination blade 1; the diameter-changing mechanism includes a diameter-changing block 5, a turntable 6, a fixed plate 7, a positioning housing 8, and a rotating block 9. Six diameter-changing blocks 5 are evenly distributed in the circumferential direction between the turntable 6 and the fixed plate 7; the turntable 6 has six first track grooves 601 evenly distributed in the circumferential direction, and the fixed plate 7 has six second track grooves 701 evenly distributed in the circumferential direction. The upper and lower surfaces of the diameter-changing blocks 5 are slidably installed in the corresponding track grooves of the fixed plate 7 and the turntable 6 through bosses. Since the diameter-changing blocks 5 are restricted by the turntable 6 and the fixed plate 7, rotating the turntable 6 can drive the diameter-changing blocks 5 to perform a variable-center rotational motion to achieve combined diameter changing. One end of the variable diameter block 5 is provided with an opening groove 51, and a rotating block 9 is rotatably provided in the opening groove 51. Specifically, one end of the variable diameter block 5 is rotatably connected to the rotating block 9 by a pin 14. One end of the rotating block 9 is provided with a groove 901, and the cleaning knife 1 is elastically installed in the groove 901. The positioning shell 8 is provided outside the turntable 6 and the fixed plate 7 to limit the relative position of the turntable 6 and the fixed plate 7. The positioning shell 8 is fixedly connected to the fixed plate 7, and the positioning shell 8 is adjustablely connected to the turntable 6 in the circumferential direction.
[0056] See Figure 4 , Figure 5 , Figure 10 and Figure 11As shown, one side of the variable diameter block 5 is provided with a cylindrical boss 502 that mates with the first track groove 601, and the other side of the variable diameter block 5 is provided with a straight groove boss 503 that mates with the second track groove 701. The cylindrical boss 502 is provided with a first threaded hole 504, and the straight groove boss 503 is provided with two second threaded holes 505. The cylindrical boss 502 and the straight groove boss 503 are respectively connected to the corresponding threaded holes by screws, so that the movement of the boss is restricted in the track groove.
[0057] See Figure 3 and Figure 6 As shown, the cleaning knife 1 includes a knife body 102, a knife holder 103, an arc-shaped contact surface 104, and a bottom edge 105. The knife holder 103 is provided on one side of the knife body 102, and the arc-shaped contact surfaces 104 are respectively provided on both sides of the other side to contact the surfaces of two adjacent steel wire ropes. The two arc-shaped contact surfaces 104 transition towards the middle to form the bottom edge 105. The bottom edge 105 has a certain slope, and the slope of the bottom edge 105 is consistent with the twist angle of the steel wire rope and corresponds to the gap between the two steel wire ropes. The design of this cleaning knife can achieve efficient cleaning of steel wire ropes. The design of the arc-shaped contact surface 104 can make the cleaning process radially closed. That is, when the bottom edge 105 contacts the gap and scrapes off the oil, the arc-shaped contact surface 104 can prevent the oil from entering the interior of the cleaning device, avoiding the oil on the surface of the steel wire rope being too sticky and accumulating on the surface of the cleaning knife during cleaning. Therefore, radial closure is required to prevent oil from entering the key parts of the device and causing malfunctions.
[0058] See Figure 4 and Figure 10 As shown, steel ball grooves 902 are respectively provided on both sides of the groove 901. (See Figure 902) Figure 6 — Figure 9 As shown, the tool holder 103 has a cuboid structure. A circular through hole 101 is provided through the tool holder 103 along its length. A first compression spring 2 is provided in the circular through hole 101. Steel balls 3 are provided at both ends of the first compression spring 2. The first compression spring 2 is always in a compressed state, and the steel balls 3 are in a semi-exposed state. The tool holder 103 is installed in the groove 901 through the cooperation of the steel balls 3 and the steel ball groove 902. The first compression spring 2 is in a compressed state during installation, so that the steel ball 3 is subjected to the elastic force of the first compression spring 2, and the steel ball 3 is in a semi-exposed state. Since the cleaning knife 1 has the requirement of radial extension and retraction, the hemispherical shape is designed as a straight groove, which achieves both locking and sliding effects, and prevents the first compression spring 2 from frequently extending and retracting. When the cleaning knife 1 is installed and removed, the steel ball 3 will be compressed by the change in the shape of the side wall of the rotating block 9, causing the steel ball 3 to retract into the cleaning knife 1. The steel ball 3 will automatically pop out and lock. When there is no squeezing action of the inner wall of the rotating block 9, the steel ball 3 will be partially exposed on the surface of the cleaning knife 1 under the elastic force of the first compression spring 2, which corresponds exactly to the matching steel ball groove 902, thereby achieving the locking effect.
[0059] See Figure 12 As shown, a pressure sensor 11 is provided on the bottom wall of the groove 901. A second compression spring 10 is provided between the pressure sensor 11 and the knife holder 103. One end of the second compression spring 10 is fixedly connected to the pressure sensor 11. The pressure sensor 11 is used to detect the pressure value of the second compression spring 10 and provide pressure value data to external devices, thereby detecting the pre-tightening force of the cleaning knife 1 in contact with the wire rope 4. The steel ball 3 cooperates with the steel ball groove 902 and the second compression spring 10 holds the knife holder 103, making it easy to disassemble and replace the cleaning knife 1. Considering that the cleaning knife 1 is against the steel wire rope 4 when it is cleaning, and the direction of the force exerted by the steel wire rope 4 on the cleaning knife 1 during cleaning is outward from the axis, the cleaning knife 1 will not fall out when it is working. That is, it is only necessary to consider that the cleaning knife 1 will not fall out of the rotating block 9 when it is not working. Therefore, the first compression spring 2 is set on the cleaning knife 1 to cooperate with the steel ball 3. At the same time, the steel ball groove 902 is set on the rotating block 9 so that the steel ball 3 retracts into the cleaning knife during the installation process and automatically springs back after the end to prevent the cleaning knife from falling out. By incorporating a second compression spring and a pressure sensor, the cleaning blade can radially extend and retract relative to the wire rope. This minimizes rigid contact between the cleaning blade and the wire rope surface, preventing scratches. The pressure sensor also detects the compression of the second compression spring, allowing adjustment of the preload during installation and monitoring for wear during operation. During cleaning, when the wire rope 4 applies an outward force to the cleaning blade 1, the cleaning blade 1 detaches from the wire rope 4 surface. The second compression spring 10 then springs the cleaning blade 1 back to contact the wire rope 4 again.
[0060] In this embodiment, the turntable 6, the fixed plate 7, and the positioning shell 8 are all detachable structures in two halves. The left and right halves of the turntable 6 are connected by a first bolt 12; the left and right halves of the fixed plate 7 and the positioning shell 8 are fixedly connected by a second bolt 13. See [reference needed]. Figure 2 and Figure 3 As shown, the left and right halves of the fixed plate 7 and the positioning shell 8 are respectively provided with connecting ears. The connecting ear hole 702 of the fixed plate and the connecting ear hole 802 of the positioning shell are fixedly connected by the second bolt 13.
[0061] In this embodiment, the outer diameter of the turntable 6 is slightly larger than the outer diameter of the fixed plate 7, and the inner wall contour of the positioning shell 8 matches the turntable 6, thereby achieving radial positioning of the turntable 6, the variable diameter block 5, and the fixed plate 7.
[0062] See Figure 2 and Figure 5As shown, the left and right halves of the turntable 6 are each equipped with a handle 602, and the handle 602 has a diameter-changing positioning hole 603. The left and right halves of the positioning housing 8 are each equipped with an angle adjustment plate 806, and the angle adjustment plate 806 has several angle holes 803 evenly distributed around the turntable axis. The positioning housing 8 and the turntable 6 are connected by a pin 15 inserted into the diameter-changing positioning hole 603 and the corresponding angle hole 803. When the turntable 6 is rotated, that is, after the decontaminator changes diameter, the turntable 6 and the positioning housing 8 are fixedly connected by a pin inserted into the corresponding angle hole 803, so that the decontaminator 1 remains in contact with the wire rope 4. This invention, by setting multiple angle holes on the angle adjustment plate 806, can lock the diameter-changing mechanism when it changes to a certain size, ensuring that the cleaning blade remains in elastic contact with the wire rope during the cleaning operation. It is also easy for operators to use. Since the diameter change of this device requires manual rotation of the turntable, handles on both sides of the turntable are provided for easy rotation. The cleaner does not actually require stepless diameter change during operation; the locking after diameter change is used to counteract the axial outward force applied to the cleaning blade by the wire rope during cleaning, ensuring that the cleaner matches the diameter of the wire rope during operation.
[0063] See Figure 13 and Figure 14 As shown, the two halves of the positioning housing 8 are respectively provided with a positioning shoulder 801 that matches the turntable 6, a first clearance groove 804 for the handle 602 to rotate and make room, and a second clearance groove 805 for the connecting part of the left and right halves of the turntable 6 to rotate and make room. This can prevent interference and allow the assembled turntable 6 to rotate and adjust freely.
[0064] See Figure 2 As shown, the axial limiter includes a limiter housing 16, a guide sleeve 17, and lifting rings 19. The limiter housing 16 is designed as a cube. The guide sleeves 17 are rotatably provided at both ends of the limiter housing 16. Both the limiter housing 16 and the guide sleeves 17 have through holes at their axial positions that match the outer diameter of the wire rope 4. Multiple lifting rings 19 are provided on the outer wall of the limiter housing 16. The limiter housing 16 can be fixed by ropes by setting the lifting rings 19.
[0065] In this embodiment, both the limiter housing 16 and the guide sleeve 17 are designed as two-half structures, and the two halves of the limiter housing 16 are fixedly connected by a third bolt 18. By setting the guide sleeve 17, the wire rope 4 can pass smoothly through the decontaminator, preventing the wire rope 4 from being bent or broken during decontamination, which would affect the normal progress of the decontamination work.
[0066] See Figures 15 to 19As shown, the sliding oil application device includes a housing 21, a bushing 22 disposed inside the housing 21, and a sealing sleeve 20 embedded at both ends of the housing 21. A sealed channel for the steel wire rope to pass through is formed between the bushing 22 and the sealing sleeve 20. The bushing 22 is provided with a bushing oil inlet 42 and a bushing oil return outlet 44 on both sides.
[0067] Specifically, the housing 21 consists of two semi-circular housings. One side of the two semi-circular housings is hinged, and the other side is connected to a locking component and a handle. The two semi-circular housings can be opened, and because the two semi-circular housings are hinged open, they are not easy to lose, and the positioning is reliable.
[0068] One of the semi-circular housings is the oil return housing 36, which has an oil return passage 33 that corresponds to the bushing oil return port 44 and communicates with the housing oil return port 43 (see...). Figure 4 As shown), the other semi-circular shell is the oil filling shell 35. The side of the oil filling shell 35 is provided with a pressurization chamber 27, a motor chamber 28 and a cover 24. The pressurization chamber 27 is provided with a pressurization screw 23. The motor chamber 28 is provided with a motor connected to the pressurization screw 23. One end of the cover 24 is hinged to the oil filling shell 35 by a hinge 29, and the other end of the cover 24 is sealed and fixed to the oil filling shell 35 by screws.
[0069] See Figure 19 As shown, the hatch cover 24 includes an integrated front hatch cover 39 and a rear hatch cover 40. The front hatch cover 39 and the rear hatch cover 40 are respectively connected to the pressurization chamber 27 and the motor chamber 28 to form a closed chamber. The hatch cover 24 is provided with an oil inlet 41, and the pressurization chamber 27 is provided with an oil inlet passage 32 corresponding to the bushing oil inlet 42.
[0070] See Figure 16 As shown, the sealing sleeve 20 consists of two sealing sleeve halves. Between the two half-sleeves, multiple gradually decreasing lubricating oil sealing grooves 47 and sponge sealing grooves 45 are formed from the inside to the outside. A lubricating oil sealing ring is installed within the lubricating oil sealing groove 47, and a sponge sealing ring is installed within the sponge sealing groove 45. Both the lubricating oil sealing ring and the sponge sealing ring are annular structures formed by two half-rings joined together. The lubricating oil sealing ring and the sponge sealing ring reduce lubricating oil leakage. Furthermore, both the sealing sleeve 20 and the inner liner 22 can be selected in appropriate sizes according to the dimensions of different wire ropes.
[0071] See Figure 16 As shown, the outer surfaces of the two sealing sleeve halves are provided with semi-circular grooves 46, and the two sealing sleeve halves are fixed together by clamps matching and fixing with the semi-circular grooves 46.
[0072] See Figure 16 and Figure 19As shown, bushing 22 consists of two half bushings, namely oil injection half bushing 37 and oil return half bushing 38, which are nested in two semi-circular shells respectively.
[0073] See Figure 16 As shown in this embodiment, multiple sets of annular oil grooves are formed at both ends between the two half bushings, which can limit the flow range of lubricating oil and reduce oil leakage.
[0074] See Figure 15 , Figure 16 and Figure 19 As shown in this embodiment, hinge ears are provided on the middle two sides of one side of the two semi-circular shells, and the corresponding hinge ears are hinged together by hinge bolts 25.
[0075] See Figure 15 , Figure 16 and Figure 19 As shown, in this embodiment, the handle consists of two half-handles respectively disposed on two housings 21. The locking assembly includes a locking block 34, a fisheye screw 26, and a wing nut 26. Locking blocks 34 are respectively provided at both ends of the two semi-circular housings near the corresponding half-handles. The fisheye end of the fisheye screw 26 is rotatably disposed between the locking block 34 and the half-handle on the oil return housing 36. The screw end of the fisheye screw 26 is provided with a wing nut 26. The wing nut 26 locks the corresponding half-handle and the locking block 34, so that the two semi-circular housings are fixed to form a complete structure.
[0076] See Figure 15 As shown, the housing 21 is provided with radially symmetrical positioning ears at both ends, and positioning ear holes 30 are provided on the positioning ears. Rope buckles can be installed through the positioning ear holes 30 to fix the spatial position of the entire device.
[0077] See Figure 16 As shown, each of the two semi-circular shells is provided with a shell sealing oil groove 31, and a sealing gasket is provided in each shell sealing oil groove 31. The sealing gasket can prevent oil leakage when the two semi-circular shells are combined.
[0078] This invention uses a six-strand steel wire rope 4 as the object of cleaning and maintenance. Its installation and working principle are briefly described below. The direction of movement of the steel wire rope 4 is set from right to left (see...). Figure 1(As shown); before cleaning the wire rope 4 in the decontaminator, a custom-made decontamination blade 1 needs to be selected to match the diameter and twist angle of the wire rope 4. The diameter of the wire rope affects the curvature of the decontamination blade 1; a thicker wire rope corresponds to a larger decontamination blade. Because the helix angle of the wire rope gap is affected by the twist angle, the bottom edge 105 of the decontamination blade is oblique, not straight. Furthermore, the twist angle varies depending on the load of the same diameter wire rope. During installation, first install the decontamination blade 1 onto the rotating block 9, then fit the wire rope 4 into the diameter changing mechanism and assemble it. The operator manually rotates the turntable 6 to perform stepless diameter changing. The working principle of the diameter changing mechanism is as follows: The principle is that rotating the turntable 6 will drive the diameter-changing block 5 to move, but at the same time, the rear side of the diameter-changing block is affected by the fixed plate 7, thus realizing a regular and continuous diameter-changing movement. Then, the direction of the cleaning knife 1 is adjusted by rotating the block 9. The pressure value data is observed by external equipment, and the rotation angle of the turntable 6 is adjusted to adjust the elasticity of the second compression spring 10, thereby indirectly adjusting the preload of the cleaning knife 1, so that the cleaning knife 1 contacts the wire rope 4. Then, the turntable 6 is fixedly connected to the positioning shell 8 by the pin 15, thus realizing the diameter-changing locking. Finally, the axial limiter is suspended on the bracket by the hanging ring 19.
[0079] When the wire rope winch is started and the wire rope moves from right to left, the axial limiter will prevent the cleaner from moving to the left, converting the cleaner's movement into a rotational motion on a plane. The cleaner blade 1 will move along the gaps in the wire rope to scrape out the dirt in the gaps, thereby achieving wire rope cleaning. After the wire rope has completed a section of cleaning, stop the wire rope winch and install the oiling device.
[0080] Before installing the oiling device, it is necessary to select the appropriate sealing sleeve 20 and bushing 22 according to the diameter of the wire rope. Set the corresponding lubricating oil sealing ring half ring and sponge sealing ring half ring in the corresponding sealing sleeve half ring. Attach the oiling device to the cleaned part of the wire rope. Specifically, open the oiling device, place the wire rope into the return oil housing 36, the return oil half bushing 38, the sealing sleeve half ring and the corresponding sealing ring half ring, rotate the oil filling housing 35 to close the oil filling housing 35 and the return oil housing 36, and fix the two semi-circular housings to form a complete housing structure through the fisheye screw 26 and the wing nut 26 to complete the sealing assembly. After the sealing assembly is completed, install rope buckles at the positioning ear holes 30 at both ends to fix the spatial position of the entire device and prevent device vibration and undesirable movement.
[0081] After the oiling device is installed, lubricating oil is pumped into the pressurization chamber 27 through the oil inlet 41. The lubricating oil enters the pressurization chamber 27 through the oil inlet 41. The motor is turned on, and under the action of the pressurizing screw 23, the lubricating oil is pushed into the oil inlet passage 32. It enters the bushing 22 through the bushing oil inlet 42 and is sprayed onto the surface of the wire rope under a certain pressure, which can evenly coat the wire rope and achieve uniform oil immersion. When the lubricating oil in the bushing reaches a certain pressure, the lubricating oil will be discharged from the housing oil return port 43 through the bushing oil return port 44 and the oil return passage 33, which can realize the recycling of lubricating oil. The wire rope winch is started again. Under the drive of the winch, the wire rope can achieve continuous online decontamination and oiling operations under the action of the decontamination device and the oiling device. It is worth noting that the variable diameter mechanism of this invention can achieve a stepless variable diameter effect with high space utilization. The same cleaning device can adapt to wire ropes 4 with the same number of strands, different diameters, and different lay angles, and the number of variable diameter blocks can be changed to adapt to wire ropes 4 with different numbers of strands. If the wire rope has slight radial displacement, the lubrication and oiling device can also be adjusted accordingly, or a slide rail can be installed at the end of the rope buckle for relative movement. The mating seal at both ends, the flow and circulation of grease, and the internal pressure balance ensure the stability and safety of the internal space.
