Description

A variable diameter wire rope decontamination device Technical Field

[0001] This invention relates to the field of wire rope maintenance technology, specifically to a decontamination device for variable diameter wire ropes. Background Technology

[0002] Wire ropes, as core structural components in industrial fields, come in a wide variety of types, primarily 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, according to production safety requirements, regular cleaning and maintenance of lifting wire ropes is essential.

[0003] Existing methods for cleaning steel wire ropes mainly fall into two categories: manual hand-held wire brushing and machine-based rotating wire brushing. Manual cleaning with hand-held wire brushes is dangerous and labor-intensive. Machine-based cleaning involves bulky and expensive machinery, sometimes requiring disassembly of the wire rope. Furthermore, ordinary wire brushes are ineffective at removing dirt from the crevices of the wire rope. Therefore, it is necessary to design a steel wire rope cleaning device. Summary of the Invention

[0004] To address the gaps in existing technologies, this invention provides a variable-diameter wire rope decontaminator. This structure offers advantages such as high decontamination efficiency, adaptability to various diameter series of wire ropes, and quick installation and replacement, making it suitable for cleaning oil stains from wire ropes. It solves the problems of existing devices being bulky and cumbersome, costly to operate, and unable to handle decontamination of wire ropes of various diameters. This invention's wire rope decontamination device can be used in confined spaces without disassembling the wire rope; only the decontamination blade needs to be replaced to accommodate various diameter series of wire ropes.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A decontamination device for variable diameter steel wire rope includes a decontaminator and an axial limiter.

[0007] 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.

[0008] 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 circumferential connection to the turntable is adjustable.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] Furthermore, the axial limiter includes a limiter housing, a guide sleeve, and lifting rings. The limiter housing is designed as a cube, and the two ends of the limiter housing are rotatably provided with guide sleeves. The limiter housing and the guide sleeves are both provided with 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.

[0017] Furthermore, both the restrictor housing and the guide sleeve are designed as two-half structures, and the two halves of the restrictor housing are fixedly connected by a third bolt.

[0018] The beneficial effects of this invention are:

[0019] 1. This invention has the advantages of high decontamination efficiency and quick installation and replacement. It is suitable for cleaning oil stains on steel wire ropes. Compared with the existing technology, the device is small in size, has low operating cost, and can adapt to the decontamination of steel wire ropes of various diameters. It can work in confined spaces without disassembling the steel wire rope. Only the decontamination blade needs to be replaced to make it suitable for steel wire ropes of various diameters.

[0020] 2. The variable diameter mechanism of this invention adopts a modular design, which can achieve a stepless variable diameter effect with high space utilization. The same decontaminator can adapt to steel 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 steel wire ropes with different numbers of strands.

[0021] 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.

[0022] 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.

[0037] 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.

[0038] Example 1: As shown in Figure 1, it includes a cleaner and an axial limiter. The axial limiter is located on one side of the direction of movement of the wire rope. The axial limiter is used to restrict the cleaner from moving axially in the direction of movement of the wire rope when the wire rope moves.

[0039] The specific structure of the decontaminator is shown in Figures 2-13. 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 shell 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. Six first track grooves 601 are evenly distributed in the circumferential direction on the turntable 6, and six second track grooves 701 are evenly distributed in the circumferential direction on the fixed plate 7. 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.

[0040] 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.

[0041] Referring to Figures 3, 4, 9, and 10, 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.

[0042] Referring to Figures 2 and 5, the cleaning knife 1 includes a knife body 102, a knife holder 103, an arc-shaped contact surface 104, and a bottom edge 105. One side of the knife body 102 has a knife holder 103, and the other side has arc-shaped contact surfaces 104 on both sides that 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 angle, which is consistent with the twist angle of the steel wire rope and corresponds to the gap between the two steel wire ropes. This cleaning knife design enables efficient cleaning of the steel wire rope. The arc-shaped contact surface 104 design allows for radial closure during the cleaning process. That is, when the bottom edge 105 contacts the gap and scrapes off the oil, the arc-shaped contact surface 104 prevents oil from entering the cleaning device, avoiding the accumulation of highly viscous oil on the surface of the steel wire rope on the cleaning knife surface during cleaning. Therefore, radial closure is required to prevent oil from entering critical parts of the device and causing malfunctions.

[0043] Referring to Figures 3 and 9, steel ball grooves 902 are respectively provided on the two side walls of the groove 901. Referring to Figures 5-8, the tool holder 103 is a cuboid structure. A circular through hole 101 is provided through the tool holder 103 along the length direction. 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 grooves 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.

[0044] Referring to Figure 11, 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.

[0045] 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 the first bolt 12. The left and right halves of the fixed plate 7 and the positioning shell 8 are fixedly connected by the second bolt 13. As shown in Figures 1 and 2, 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.

[0046] 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.

[0047] Referring to Figures 1 and 4, the left and right halves of the turntable 6 are each equipped with a handle 602, and each 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, which has several angle holes 803 evenly spaced around the turntable's 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 holes 803. When the turntable 6 is rotated, i.e., after the decontaminator changes diameter, the turntable 6 and the positioning housing 8 are fixedly connected by the pin inserted into the corresponding angle holes 803, ensuring that the decontaminator blade 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.

[0048] Referring to Figures 12 and 13, 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.

[0049] Referring to Figure 1, 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 using the lifting rings 19.

[0050] 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.

[0051] This invention uses a six-strand steel wire rope 4 as the object of decontamination. Its installation and working principle are briefly described as follows: The movement direction of the steel wire rope 4 is set vertically upward. Before the decontaminator decontaminates the steel wire rope 4, a customized decontamination blade 1 needs to be selected to match the diameter and twist angle of the steel wire rope 4. The diameter of the steel wire rope affects the curvature of the decontamination blade 1; a thicker steel wire rope corresponds to a larger decontamination blade. Because the helix angle of the steel 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 on the same diameter steel wire rope. During installation, the decontamination blade 1 is first installed on the rotating block 9, the steel wire rope 4 is fitted into the diameter-changing mechanism and assembled. The operator manually rotates the turntable 6 for stepless diameter changing. The working principle of the diameter changing is to rotate the turntable 6. The variable diameter block 5 moves, but its rear side is affected by the fixed plate 7, thus achieving a regular and continuous variable diameter movement. The direction of the cleaning blade 1 is adjusted by rotating block 9, and pressure data is observed through external equipment. The rotation angle of turntable 6 is adjusted to adjust the elasticity of the second compression spring 10, thereby indirectly adjusting the preload of the cleaning blade 1, making it contact the wire rope 4. Then, turntable 6 is fixedly connected to positioning housing 8 by pin 15, thus achieving variable diameter locking. Due to the obstruction of oil stains on the surface of the wire rope 4, the device will not descend. Finally, the axial limiter is suspended on the bracket by the hanging ring 19, preventing the variable diameter mechanism from rising, converting the spiral upward motion of the cleaning device during cleaning into a planar rotational motion, thus achieving continuous cleaning. 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 twist angles, and the number of diameter blocks can be changed to adapt to wire ropes 4 with different numbers of strands.
