Description

Technical Field

[0001] The present invention relates to lifting equipment, and particularly to a wire rope cleaning device, which can be used in lifting equipment. Background Art

[0002] As a traction medium, wire ropes are widely used in the suspension systems of elevators. The wire ropes are suspended in the hoistway. As the service time of the elevator increases, the grease inside the wire ropes seeps out to the surface. Due to the relatively harsh environment in the hoistway, the grease is extremely likely to adhere to impurities such as dust in the hoistway environment, forming sludge that adheres to the surface of the wire ropes. As a result, the working conditions deteriorate when the wire ropes mesh with the traction wheels, affecting the traction capacity and the service lives of the wire ropes and the traction wheels. In severe cases, it may even cause the wire ropes to jump out of the wheel grooves, posing a great potential safety hazard to the operation of the elevator. However, the conventional cleaning of wire ropes currently implemented is difficult to simultaneously remove the dirt on the surface of the wire strands and between the wire strands. Therefore, how to design a device that can comprehensively clean the surface of the wire ropes and between the wire strands has become an urgent problem to be solved.

[0003] In the wire rope cleaning device for elevators with the application number 201920572008.3, the wire rope is passed through the middle of two cleaning grooved wheels, and the dirt on the surface of the wire rope is cleaned by the brushes on the two cleaning grooved wheels. Since the wire rope is twisted, this device cannot effectively clean the dirt between the wire strands of the wire rope.

[0004] In the wire rope cleaning devices invented in the applications with the numbers 201210501981.9 and 201310203837.1, there is a cylindrical rotating part with an inner surface having the same spiral shape as the wire rope, and the wire rope is cleaned by this rotating part. Although this structure can clean the dirt between the wire strands of the wire rope, the spiral shape of the inner surface of this rotating part is determined, and it can only clean wire ropes with specific lay directions and lay lengths, with relatively large limitations in on-site applications. In addition, during the cleaning process, the oil stains cleaned from the wire rope may adhere to the inner surface of this rotating part and cannot be removed in time, greatly reducing the cleaning effect. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a wire rope cleaning device that can comprehensively clean the sludge and other dirt on the surface of the wire rope and between the wire strands.

[0006] To solve the above technical problem, the present invention provides a wire rope cleaning device, including at least one brush head assembly that freely rotates around its own central axis. The surface of the brush head assembly has multiple groups of convex cleaning units that are spirally and evenly distributed, and the pitch and rotation direction of the convex cleaning units are adjusted according to the lay length and lay direction of the wire rope to be cleaned.

[0011] Preferably, adjacent outer brush discs are arranged at a set phase angle, and the phase angle is an integer multiple of the circumferential distribution angle of the spline teeth.

[0012] Preferably, at least one adjusting gasket is provided between adjacent outer brush discs to adjust the distance between adjacent outer brush discs, so that the outer circumferential contours formed by the convex cleaning units on the outer brush discs are combined into multiple sets of convex structures that are helically evenly distributed and match the lay length of the wire rope to be cleaned.

[0013] Preferably, the present invention also provides another structure of the brush head assembly, wherein the brush head assembly includes a mounting shaft, at least two outer brush discs, and at least one positioning rod. The outer brush discs are sleeved on the mounting shaft, and all the outer brush discs are connected into a whole by the positioning rod and freely rotate on the mounting shaft. A circumferentially evenly distributed convex cleaning unit and a circumferentially evenly distributed non-convex cleaning unit are provided on the outer circumference of the outer brush disc. The convex cleaning unit and the non-convex cleaning unit have different shapes and sizes, and the contour formed by the convex cleaning unit on the outer circumference of the outer brush disc is in the shape of evenly distributed periodic protrusions.

[0014] Preferably, the outer brush disc is formed with a plurality of positioning holes penetrating through both end faces. The positioning holes are used for the positioning rod to pass through, and the positioning holes are evenly distributed in a circular array on the outer brush disc.

[0015] Preferably, an adjusting gasket is provided between the outer brush discs.

[0016] Preferably, the adjusting gasket is formed with a plurality of positioning holes penetrating through both end faces. The positioning holes on the adjusting gasket have the same size, position, and distribution law as the positioning holes on the outer brush disc.

[0017] Preferably, adjacent external brush discs are arranged at a set phase angle, and the phase angle is a positive integer multiple of the central angle of a line connecting the centers of two adjacent positioning holes on the external brush disc.

[0018] Preferably, at least one adjustment gasket is provided between adjacent external brush discs to adjust the spacing between adjacent external brush discs, so that the peripheral contour formed by the raised cleaning units on the external brush discs is combined into multiple groups of raised structures that are spirally evenly distributed and match the lay pitch of the wire rope being cleaned.

[0019] Preferably, the positioning rod passes through the positioning holes of all the external brush discs and the adjusting washers, connecting the external brush discs and the adjusting washers in series to form a whole that can rotate freely on the mounting shaft.

[0020] Preferably, the hardness of the material of the raised cleaning units is higher than that of the material of the non-raised cleaning units.

[0021] Preferably, the adjusting gasket and the external brush disc are both hollow disc-shaped.

[0022] Preferably, the outer diameter of the adjusting gasket is smaller than the outer diameter of the outer brush disc.

[0023] Compared with the prior art, the beneficial technical effects achieved by the present invention are:

[0024] First, the wire rope cleaning device of the present invention is provided with multiple groups of spirally evenly distributed raised cleaning units on the surface of the brush head assembly. The profile formed by these raised cleaning units on the outer periphery of the brush head assembly is a uniformly distributed periodic raised shape. By adjusting the staggered phase angle between the external brush discs in the brush head assembly and the number of adjustment spacers between adjacent external brush discs, raised structures with different rotation directions and pitches can be obtained, thereby being able to clean wire ropes with different lay directions and lay pitches.

[0025] Second, based on the characteristics of the gaps between the strands of the wire rope and the location of dirt on the surface of the strands, the wire rope cleaning device of the present invention is provided with raised cleaning units and non-raised cleaning units of different shapes and sizes on the surface of the brush head assembly. The raised cleaning units are used to handle impurities such as oil sludge embedded between the strands of the wire rope, while the non-raised cleaning units are used to handle oil stains on the surface of the strands, thereby ensuring a better cleaning effect.

[0026] Third, the wire rope cleaning device of the present invention is easy to install and maintain, will not cause rigid friction with the wire rope during cleaning, will not damage the wire rope, and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Figure 1 is a system schematic diagram of a traction elevator system 10 with a suspension ratio of 1:1. The system includes a car 11 and a corresponding counterweight 12. The car 11 and the counterweight 12 are respectively directly connected to a steel wire rope 14. The traction wheel 16 of the traction machine 13 drives the steel wire rope 14 to move, completing the ascending and descending movements of the car 11. The function of the guide wheel 17 is to maintain the distance between the car 11 and the counterweight 12. The steel wire rope cleaning device 15 is preferably fixed near the traction machine 13, such as on the traction machine base or the load-bearing beam. When the car 11 ascends or descends, the steel wire rope cleaning device 15 can clean the passing steel wire rope.

[0042] Figure 2 is a system schematic diagram of another traction elevator system 20 with a suspension ratio of 2:1. The system includes a car 11 and a corresponding counterweight 12. The car 11 and the counterweight 12 are respectively suspended on the steel wire rope 14 through their respective deflecting sheaves 18, and both ends of the steel wire rope 14 are fixed relative to space. The traction wheel 16 of the traction machine 13 drives the steel wire rope 14 to move, completing the ascending and descending movements of the elevator car 11. Similar to Figure 1 the steel wire rope cleaning device 15 is preferably fixed near the traction machine 13, such as on the traction machine base or the load-bearing beam; in addition, the steel wire rope cleaning device 15 can also be installed at an appropriate position on the car 11 or the counterweight 12, such as on the upper beam of the car frame or the upper part of the counterweight frame. When the elevator car 11 ascends or descends, the steel wire rope cleaning device 15 can clean the passing steel wire rope 14.

[0043] Figure 3 is Figure 1 and Figure 2 the installation position diagram of the steel wire rope cleaning device 15 corresponding to the steel wire rope in. The steel wire rope cleaning device 15 is jointly composed of a brush head assembly 60 and a connecting seat 67 connecting them. The connecting seat 67 can be installed at positions such as the above-mentioned traction machine base, load-bearing beam, upper beam of the car frame, and counterweight frame.

[0044] The steel wire rope cleaning device of the present invention includes at least one brush head assembly. The brush head assembly rotates freely around its own central axis. There are multiple groups of raised cleaning units spirally distributed on the surface of the brush head assembly. The pitch and rotation direction of the raised cleaning units are adjusted according to the lay length and lay direction of the steel wire rope to be cleaned.

[0045] As Figure 3 shown, wire ropes 65 and 66 are each cleaned by two brush head assemblies 60. The arrangement of the brush head assemblies and the wire ropes is not limited to Figure 3 the way shown. Each wire rope can also be cleaned by multiple brush head assemblies arranged in an annular array. As Figure 4 shown, wire rope 65 is cleaned by three brush head assemblies 60. Preferably, the three brush head assemblies 60 can be evenly distributed on the circumferential side of the wire rope, that is, the angle between two adjacent brush head assemblies 60 is 120°. Of course, a wire rope can also be cleaned by one brush head assembly.

[0046] Figure 5 and Figure 6 Fig. is Embodiment 1 of the brush head assembly in a wire rope cleaning device 15 provided by the present invention. In this Embodiment 1, the brush head assembly 61 can freely rotate around its own central axis 09. Figure 6 Fig. is a schematic diagram of the brush head assembly 61 without the upper sealing plate 07 installed.

[0047] As Figure 5 and Figure 6 shown, the brush head assembly 61 includes a mounting shaft 01, an inner bushing 02, an outer brush disc 03, an adjusting shim 04, and an upper sealing plate 07. The inner bushing 02 is a hollow external spline structure, that is, the outer circumference of the inner bushing 02 has external splines. It is sleeved on the mounting shaft 01. Lubricating oil or bearings can be added between the inner bushing 02 and the mounting shaft 01 to facilitate the free rotation of the brush head assembly 61 around the central axis of the mounting shaft 01.

[0048] The outer ring of the outer brush disc 03 is a circumferentially evenly distributed flexible cleaning unit with different outer dimensions, and the inner ring is an internal spline structure, which is installed in cooperation with the external spline structure of the inner bushing 02. Adjusting shims 04 can be arranged between the outer brush discs 03. The inner ring of the adjusting shim 04 has internal splines that cooperate with the external splines of the inner bushing 02. In this Embodiment 1, the shoulder on the mounting shaft 01 and the upper sealing plate 07 limit the spaced-apart inner bushing 02 and outer brush disc 03 axially.

[0049] In Figure 5 and Figure 6In the illustrated embodiment 1, the brush head assembly 61 is composed of six external brush discs 03 and five internal bushings 02 mounted on the mounting shaft 01, which are connected in series via spline engagement. Adjacent external brush discs 03 are arranged at a certain phase angle, which is a positive integer multiple of the circumferential distribution angle of the spline teeth. In this embodiment 1, two adjacent external brush discs 03 are arranged with two spline teeth staggered in phase, and an adjustment gasket 04 is inserted between adjacent external brush discs 03 to adjust the spacing between the two adjacent external brush discs 03. This allows the contours formed by the raised flexible cleaning units on the outer circumference of the external brush discs 03 to be combined into multiple groups of spirally evenly distributed raised structures 68, which precisely match the lay direction and lay pitch of the wire rope being cleaned. By adjusting the staggered phase angles between adjacent external brush discs 03 and increasing or decreasing the number of adjustment gaskets 04 between adjacent external brush discs 03, a raised structure consisting of flexible cleaning units at raised positions with different rotation directions and pitches can be obtained, thereby being suitable for cleaning steel wire ropes with different twist directions and twist pitches.

[0050] Figure 7 for Figure 5 、 Figure 6 The schematic diagram of the installation shaft 01 in the embodiment 1 shown in FIG. 1 includes a shaft handle 101, a shaft shoulder 102, and a shaft body 103. The brush head assembly 61 is fixed to the shaft handle 101. Figure 3 On the connecting seat 67 of the wire rope cleaning device 15 shown, a shoulder 102 is used to axially limit the internal bushing 02 and external brush plate 03 in the brush head assembly 61 mounted on the mounting shaft body 103. The mounting shaft body 103 is used to fit the internal bushing 02, and a threaded hole 104 is formed at the top of the mounting shaft body 103. The upper sealing plate 07 is fixed to the mounting shaft 01 via bolts 08 installed in the threaded hole 104.

[0051] Figure 8 for Figure 5 、 Figure 6 The schematic diagram of the inner bushing 02 in the embodiment 1 is shown. The outer periphery of the inner bushing 02 has an outer spline 21. Figure 8 The external spline 21 is shown as an involute shape, but this embodiment is not limited thereto. The external spline 21 may also be rectangular, triangular, or other shapes. The internal bushing 22 is inserted through the inner hole 22 and freely rotates on the mounting shaft body 103 of the mounting shaft 01. The internal bushing 02 and the mounting shaft 01 may be directly mated, or a rolling bearing may be added between them to facilitate the rotation of the internal bushing 02.

[0052] Figure 9 for Figure 5 、 Figure 6Schematic diagram of the external brush disc 03 in the first embodiment shown. The inner ring of the rigid body of the external brush disc 03 has an internal spline 33 that mates with the external spline 21 of the internal bushing 02; circumferentially evenly distributed flexible cleaning units with different outer dimensions are provided on the outer ring of the rigid body. Among them, the flexible cleaning unit at the convex position is the convex cleaning unit 31, and the flexible cleaning unit at the non-convex position is the non-convex cleaning unit 32. The hardness of the material forming the convex cleaning unit 31 can be higher than the hardness of the material forming the other non-convex cleaning units 32. The convex cleaning unit 31 can be a metal wire (such as steel wire, copper wire, etc.), or a non-metal wire (such as nylon wire, polyethylene wire, polypropylene wire, polybutylene terephthalate wire, etc.), and the non-convex cleaning unit 32 is a non-metal wire (such as nylon wire, polyethylene wire, polypropylene wire, polybutylene terephthalate wire, etc.) or a non-metal flexible block material (such as soft polyurethane foam, emery fiber, etc.). Preferably, the convex cleaning unit 31 is copper wire, and the non-convex cleaning unit 32 is soft polyurethane foam. Because the copper wire has a higher hardness, it is convenient to clean the sludge and impurities embedded between the rope strands, and the soft polyurethane foam has better adhesion, which is convenient for cleaning the oil stains on the surface of the rope strands. Therefore, it is not easy to damage the steel wire rope while achieving a good cleaning effect.

[0053] Figure 10 For Figure 5 , Figure 6 Schematic diagram of the adjusting gasket 04 in the first embodiment shown. The inner ring of the adjusting gasket 04 has an internal spline 41 that mates with the external spline 21 of the internal bushing 02, and the outer diameter of the outer ring is smaller than the outer diameter of the rigid body of the external brush disc 03. By adjusting gaskets 04 with different thicknesses and numbers, the Figure 5 axial distance between the external brush discs 03 in the first embodiment shown can be adjusted, so as to realize the convex structures with different pitches on the surface of the brush head assembly 61.

[0054] Figure 11This is the second embodiment of the brush head assembly in the wire rope cleaning device 15 provided by the present invention. In this second embodiment, the brush head assembly 50 can rotate freely around its own central axis 51. The brush head assembly 50 includes a mounting shaft 01, an external brush disc 52, a positioning rod 53, an adjustment gasket 54, and an upper sealing plate 07. The outer ring of the external brush disc 52 is a flexible cleaning unit that is uniformly distributed circumferentially and has different external dimensions. The inner hole of the rigid body of the external brush disc 52 can be freely rotated on the mounting shaft 01. The external brush disc 52 is formed with a plurality of positioning holes that pass through the two end faces. The positioning holes are used for the positioning rod 53 to pass through, and the positioning holes are evenly distributed in a circular array on the external brush disc 52. Both ends of the positioning rod 53 are threaded and can be fixed with nuts. Adjustment gaskets 54 can be set between the external brush discs 52. The external brush discs 52 and the adjustment gaskets 54 are connected in series through the positioning rod 53 to form a whole set on the mounting shaft 01. The upper sealing plate 07 is fixed to the mounting shaft 01 by bolts 08. The external brush disc 52 is limited in the axial direction by the shaft shoulder on the mounting shaft 01 and the upper sealing plate 07.

[0055] exist Figure 11 In the second embodiment shown, the brush head assembly 50 uses four positioning rods 53 that pass through the circular array of positioning holes on the six external brush discs 52 and five adjustment washers 54, connecting the external brush discs 52 and adjustment washers 54 into a rotating unit, which is then mounted on the mounting shaft 01. Adjacent external brush discs 52 are arranged at a phase angle, which is a positive integer multiple of the central angle subtended by the line connecting the centers of two adjacent positioning holes on the external brush discs. In this second embodiment, adjacent external brush discs 52 are installed one hole apart, and two adjustment washers 54 are inserted between adjacent external brush discs 52 to adjust the spacing between them. This allows the raised flexible cleaning units on the external brush discs 03 to form a profile on the outer circumference of the external brush discs 52, forming multiple groups of spirally distributed raised structures 55 that precisely match the lay direction and lay pitch of the wire rope being cleaned. By adjusting the staggered phase angles between adjacent external brush discs 52 and increasing or decreasing the number of adjustment gaskets 54 between connected external brush discs 52, a raised structure consisting of flexible cleaning units at raised positions with different rotation directions and pitches can be obtained, which is suitable for cleaning wire ropes with different twist directions and twist pitches.

[0056] Figure 7 for Figure 11 The schematic diagram of the mounting shaft 01 in the second embodiment shown in FIG. 1 includes a shaft handle 101, a shaft shoulder 102, and a mounting shaft body 103. The brush head assembly 61 is fixed to the shaft handle 101. Figure 3 On the connecting seat 67 of the wire rope cleaning device 15 shown, the outer diameter of the shaft shoulder 102 is smaller than Figure 11The distance between the middle positioning rod 53 and the fixing nut above it to the central shaft 51 is ensured so that the positioning rod 53 and the nut above it do not interfere with the shaft shoulder 102, and the shaft shoulder 102 is used to axially limit the external brush disc 52 in the brush head assembly 50 mounted on the mounting shaft body 103. The mounting shaft body 103 is used to sleeved with the external brush disc 52 and a possible adjusting gasket 54. A threaded hole 104 is machined at the top of the mounting shaft body 103 for mounting the upper sealing plate 07. The rigid inner hole 521 of the external brush disc 52 can be directly sleeved on the mounting shaft 01 and rotate freely, or a rolling bearing can be added between the external brush disc 52 and the mounting shaft 01 to facilitate the rotation of the external brush disc 52.

[0057] Figure 12 For Figure 11 Schematic diagram of the external brush disc 52 in Embodiment 2 shown. The rigid inner ring of the external brush disc 52 is a cylindrical inner hole 521, which can be fitted and mounted on the mounting shaft body 103 of the mounting shaft 01. A plurality of positioning holes 522 evenly distributed in a circular array are machined on the rigid body of the external brush disc 52. These positioning holes 522 penetrate through both end faces of the external brush disc 52, and the central axis of the positioning holes 522 is parallel to and at an equal distance from the central axis of the cylindrical inner hole 521. Circumferentially evenly distributed flexible cleaning units with different outer dimensions are arranged on the outer ring of the rigid body of the external brush disc 52. Among them, the flexible cleaning unit at the raised position is the raised cleaning unit 523, and the flexible cleaning unit at the non-raised position is the non-raised cleaning unit 524. The material hardness of the raised cleaning unit 523 can be higher than that of the other non-raised cleaning units 524. The raised cleaning unit 523 can be a metal wire (such as steel wire, copper wire, etc.), or a non-metal wire (such as nylon wire, polyethylene wire, polypropylene wire, polybutylene terephthalate wire, etc.), while the non-raised cleaning unit 524 is a non-metal wire (such as nylon wire, polyethylene wire, polypropylene wire, polybutylene terephthalate wire, etc.) or a non-metal flexible block material (such as soft polyurethane foam, emery fiber, etc.). Preferably, the raised cleaning unit 523 is copper wire, and the non-raised cleaning unit 524 is soft polyurethane foam. Because the copper wire has a higher hardness, it is convenient to clean the sludge and impurities embedded between the cleaning strands, and the soft polyurethane foam has better adhesion, which is convenient for cleaning the oil stains on the surface of the cleaning strands. Therefore, it is not easy to damage the steel wire rope while achieving a good cleaning effect.

[0058] Figure 13 For Figure 11Schematic diagram of the adjusting shim 54 in the second embodiment shown. The inner ring of the adjusting shim 54 is a cylindrical positioning hole 541, which can be fitted and installed on the mounting shaft body 103 of the mounting shaft 01. A plurality of positioning holes 542 that are evenly distributed in a circular array and match the end face of the external brush disc 52 are machined on the adjusting shim 54. The dimensions, positions, and distribution rules of these positioning holes 542 are the same as those of the positioning holes 522 on the external brush disc 52. The outer diameter of the outer ring of the adjusting shim 54 is smaller than the outer diameter of the rigid body of the external brush disc 52. By using adjusting shims 54 with different thicknesses and quantities, Figure 11 the axial distance between the external brush discs 52 in the second embodiment shown can be adjusted to achieve raised structures with different pitches on the surface of the brush head assembly 50.

[0059] The wire rope cleaning device of the present invention is provided with multiple groups of raised cleaning units that are spirally and evenly distributed on the surface of the brush head assembly. The contours formed by these raised cleaning units on the outer periphery of the brush head assembly are in the shape of periodically raised and evenly distributed shapes. By adjusting the phase angle between the external brush discs in the brush head assembly that are staggered and the quantity of the adjusting shims between adjacent external brush discs, raised structures with different rotation directions and pitches can be obtained, so as to be able to clean wire ropes with different lay directions and lay lengths. The wire rope cleaning device of the present invention is provided with raised cleaning units and non-raised cleaning units with different shape dimensions on the surface of the brush head assembly according to the position characteristics of the strand gaps and the dirt on the strand surfaces of the wire rope. The raised cleaning units are used to process impurities such as sludge embedded between the wire rope strands, and the non-raised cleaning units are used to process the oil stains on the strand surfaces, so as to ensure better cleaning effects. The wire rope cleaning device of the present invention is convenient for installation and maintenance, will not rigidly rub against the wire rope during cleaning, will not damage the wire rope, and has a lower cost.

The above embodiments are only the preferred embodiments of the present invention, and the present invention is not limited to the above-mentioned embodiments.
