Description

Technical Field

[0001] The present application relates to the field of elevators, and in particular to an elevator traction rope cleaning device and an elevator. Background Art

[0002] The elevator traction rope is one of the main components of the elevator, and it plays a vital role in the normal and safe use of the elevator.

[0003] The elevator traction rope is generally a steel wire rope, and the elevator traction rope generally contains a certain amount of grease. The grease can keep the elevator traction rope and the rope wheel lubricated at all times, avoiding dry friction between metals and reducing the life of the elevator traction rope and rope wheel. However, in actual use, there will be a certain amount of dust and other impurities in the elevator shaft. Especially when the building is under renovation, a large amount of decoration dust may enter the elevator shaft. Dust and impurities are easy to adhere to the grease of the elevator traction rope. Over time, a thick layer of sludge will form on the surface of the elevator traction rope. In addition, the sludge will continue to absorb the grease inside the elevator traction rope during the drying process, resulting in a lack of lubrication between the elevator traction rope and the rope wheel. Dry friction is prone to occur between the elevator traction rope and the rope wheel, thereby reducing the life of the elevator traction rope and the rope wheel, and bringing safety hazards to the elevator operation.

[0004] Therefore, the sludge on the surface of the elevator traction rope must be cleaned. The Chinese invention patent with the publication number "CN106698149A" discloses the "Self-cleaning Semi-automatic Lubrication and Maintenance Device for Elevator Traction Wire Rope". The device is installed on the load-bearing beam of the elevator traction machine, and a cleaning brush and an oil collecting sponge are fixed on the device, and the cleaning brush and the oil collecting sponge can contact the surface of the traction wire rope. The operation of the elevator drives the traction wire rope to move, and the cleaning brush and the oil collecting sponge can clean and lubricate the relatively moving traction wire rope. Thereby maintaining and servicing the traction wire rope and reducing the wear of the traction wire rope. Among them, the cleaning brush and the oil collecting sponge are both located on one side of the traction wire rope. Even if the cleaning brush and the oil collecting sponge have comb teeth or elastic deformation ability, the cleaning brush and the oil collecting sponge can basically only contact one side of the traction wire rope, that is, they can only clean about half of the surface area of ​​the traction wire rope, and still cannot completely remove the surface sludge.

[0005] Another method known to the inventor is to use a brush or a copper brush to clean the surface of the elevator traction rope, but this method is also difficult to fully cover the elevator traction rope. Only a certain surface of the elevator traction rope can be cleaned per unit time, and the brush is often not strong enough to remove sticky and stubborn sludge.

[0006] In addition, the utilization rate of building area is getting higher and higher, while the size of elevator shaft is getting smaller and smaller, so the thickness of rope sheave must be made smaller accordingly. This leads to the distance between elevator traction ropes becoming very close. Therefore, even if there is a cleaning device that can fully cover the elevator traction rope, it can only be applied to the occasion of a single elevator traction rope, or to the occasion where the distance between adjacent elevator traction ropes is very large. For the situation of multiple elevator traction ropes that are close to each other in the current market, the full-cover cleaning device is difficult to install because there is a lack of necessary installation space, and the cleaning device and the adjacent elevator traction ropes will inevitably interfere.

[0007] Therefore, a cleaning device for elevator traction ropes is needed. On the one hand, it can meet the increasingly comprehensive and high requirements for cleaning effects of elevator traction ropes, and on the other hand, it can also adapt to the increasingly narrow elevator shaft space. Summary of the invention

[0008] This application is made in view of the above-mentioned state of the prior art. In a first aspect, the application provides an elevator traction rope cleaning device.

[0009] The technical solution adopted in the present application includes: multiple cleaning modules, each of which includes a cleaning core and a bearing mechanism; the cleaning core is used to circumferentially embrace the elevator traction rope, the cleaning core includes a through cavity, the inner wall of the through cavity is surrounded by a plurality of tooth grooves, the tooth grooves extend in a spiral direction, the elevator traction rope includes a plurality of rope strands spirally wound with each other, the tooth grooves are used to form a concave-convex matching contact with the rope strands; the bearing mechanism is in rolling contact with the outer wall of the cleaning core, the bearing mechanism enables the cleaning core to have the degree of freedom of rotation around its own axis; a base, the base is used to fix the bearing mechanism; wherein, a plurality of the cleaning modules located on the same horizontal line form a cleaning column, the cleaning column includes a plurality of strips arranged up and down, and the cleaning modules in the upper and lower adjacent cleaning columns are arranged in an interlaced manner.

[0010] As a further improvement of the present application, the bearing mechanism includes an open bearing, and the open bearing includes bearing frames located on both sides of the cleaning core, each of the bearing frames is equipped with a plurality of rolling elements, and the connection direction between two of the open bearings in the same cleaning module is perpendicular to the arrangement direction of a plurality of the cleaning modules in a cleaning column; there is a gap between the two open bearings in the same cleaning module that is open toward the adjacent elevator traction rope.

[0011] As a further improvement of the present application, the base includes two mounting plates, the cleaning module is located between the two mounting plates, the bearing frame is assembled with the mounting plates, and the rolling body is in rolling contact with the outer wall of the cleaning core.

[0012] As a further improvement of the present application, the rolling body includes a roller, and both ends of the roller are assembled with the bearing frame.

[0013] As a further improvement of the present application, the roller is arranged obliquely, the roller is arranged around the axis of the cleaning core, and the vertical distance from the top of the roller to the axis of the cleaning core is greater than the vertical distance from the bottom of the roller to the axis of the cleaning core.

[0014] As a further improvement of the present application, a pin is installed at the axis of the roller, and both ends of the pin are assembled with the bearing frame; the roller includes a first roller, and both ends of the first roller are recessed with blind holes, and the pin includes a first pin assembled with the blind hole; and / or the roller includes a second roller, the second roller has an axially through hole, the pin includes a second pin passing through the through hole, and the second pin includes a flange portion extending radially outward, and the flange portion is in contact with the bottom shaft end of the second roller.

[0015] As a further improvement of the present application, the cleaning core is composed of a plurality of detachable petals.

[0016] As a further improvement of the present application, tooth tops are formed at the junctions of adjacent tooth grooves, the number of tooth grooves, the tooth tops and the rope strands are equal, and the helix angles of the tooth grooves, the tooth tops and the rope strands are equal.

[0017] As a further improvement of the present application, the height of the top end of the cleaning core gradually decreases along the radial outward direction.

[0018] In a second aspect, an elevator is provided, comprising the elevator traction rope cleaning device described above.

[0019] The beneficial effects of the elevator traction rope cleaning device of the present application include:

[0020] First, the cleaning core contacts the surface of the elevator traction rope. When the cleaning core and the elevator traction rope move relative to each other, the cleaning core can wipe the surface of the elevator traction rope, such as scraping off the sludge on the surface of the elevator traction rope.

[0021] Secondly, the cleaning core is a circumferentially embracing structure, and the cleaning and wiping of the surface of the elevator traction rope is not limited to one side of the elevator traction rope, so the cleaning is more comprehensive.

[0022] Thirdly, by utilizing the spiral concave-convex shape of the outer wall of the elevator traction rope, the inner wall of the cleaning core is also spirally concave-convex, and the mutual concave-convex matching realizes full surface contact between the cleaning core and the elevator traction rope, which can scrape off dirt such as sludge in the dead corners of the elevator traction rope.

[0023] Secondly, the spiral concave-convex shape of the elevator traction rope acts as a motion guide. When the cleaning core and the elevator traction rope have relative axial movement, because the cleaning core has the freedom of self-rotation, the spiral concave-convex shape will cause the cleaning core to passively rotate along the circumferential direction. In this way, no matter how long the elevator traction rope is, as long as the part passing through the cleaning core will experience the cleaning effect of the cleaning core, the axial length of the cleaning core itself does not need to be too long. The rotating cleaning core can have a better cleaning effect on the elevator traction rope.

[0024] Finally, and most importantly, because the cleaning core wraps around the elevator traction rope, the radial dimension of the cleaning module must be larger than the radial dimension of the elevator traction rope. If all the cleaning modules are on the same horizontal line, the narrow space between adjacent elevator traction ropes may not be able to accommodate all the cleaning modules. The multiple cleaning columns up and down allow the cleaning modules to be arranged in a staggered manner, and the staggered cleaning modules are easy to avoid each other. Therefore, it is also suitable for smaller elevator shafts or closer elevator traction ropes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0054] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.

[0055] The elevator traction rope cleaning device and the elevator of the present application are further described in detail below in conjunction with specific embodiments.

[0056] See also Figure 1 , Figure 2 and Fig.21 , an embodiment of the present application provides an elevator traction rope cleaning device. The cleaning device includes a plurality of cleaning modules 4 and a base 1, wherein the cleaning module 4 includes a cleaning core 42 and a bearing mechanism. The cleaning core 42 is used to circumferentially embrace the elevator traction rope 5. The cleaning core 42 is a tubular structure, which includes an axial through cavity. The inner wall of the through cavity is surrounded by a plurality of tooth grooves 423 (i.e., a circular array), and the extension direction of each tooth groove 423 is along the spiral direction. The elevator traction rope 5 is composed of a plurality of spirally wound rope strands 51, and each tooth groove 423 can achieve concave-convex matching contact with each rope strand 51. The bearing mechanism is movably assembled with the outer wall of the cleaning core 42, and the bearing mechanism enables the cleaning core 42 to have the degree of freedom of rotation around its own axis. The base 1 is used to fix the bearing mechanism to maintain the spatial position of the cleaning module 4 relative to the elevator traction rope 5. When the surface of the elevator traction rope 5 is dirty and needs to be cleaned, the elevator traction rope cleaning device of the present application is installed on the elevator traction rope 5. After cleaning, the elevator traction rope cleaning device can be disassembled and separated from the elevator traction rope 5.

[0057] In one embodiment, there are several cleaning cores 42, and each elevator traction rope 5 is wrapped with at least one cleaning module 4. Several cleaning modules 4 located on the same horizontal line form a cleaning row. There can be several cleaning rows, and they are located at different positions up and down. All cleaning rows overlap on the same vertical plane. The cleaning modules 4 of the upper and lower adjacent cleaning rows are arranged in an interlaced manner. Figure 1 In the example, the cleaning modules 4 adjacent to each other in the transverse direction are arranged alternately up and down.

[0058] The beneficial effect of the above embodiment is that because the cleaning core 42 wraps around the elevator traction rope 5, the radial dimension of the cleaning core 42 must be larger than the radial dimension of the elevator traction rope 5. If all the cleaning cores 42 are on the same horizontal line, the narrow space between adjacent elevator traction ropes 5 may not be able to accommodate all the cleaning cores 42. The high and low staggered layout allows the cleaning cores 42 to be staggered. Figure 1 In the example shown, it is sufficient as long as the gap between adjacent elevator traction ropes 5 is larger than the difference between the half width of the cleaning core 42 and the radius of the elevator traction rope 5. In other words, one cleaning core 42 can be accommodated between two adjacent elevator traction ropes 5 with one elevator traction rope 5 in between.

[0059] All the cleaning cores 42 may be arranged in two upper and lower rows, three upper and lower rows, or even more rows, so that the spacing between the cleaning cores 42 in each individual cleaning row (ie, each cleaning row) is relatively large.

[0060] In one embodiment, see Figures 9 to 26The bearing mechanism includes an open bearing 41, and the open bearing 41 includes bearing frames 411 located on both sides of the cleaning core 42. Each bearing frame 411 is equipped with a plurality of rolling elements. The connection direction between two open bearings 41 in the same cleaning module 4 is perpendicular to the arrangement direction of the plurality of cleaning modules 4 in a cleaning row (i.e., the arrangement direction of the elevator traction rope 5). Figure 1 There is a gap between the two open bearings 41 that is open to the left and right (or, to the adjacent elevator traction rope 5), and an appropriate space can be left between the open bearings 41 and the elevator traction rope 5 to avoid interference between the open bearings 41 and the elevator traction rope 5.

[0061] The beneficial effect of adopting the above embodiment is that the two open bearings 41 are located on both sides of the cleaning core 42. The bearing mechanism will inevitably enlarge the radial size of the cleaning module 4, but instead of using a complete circumferential bearing, a split bearing, i.e., two open bearings 41, can be used. By limiting the specific position of the open bearings 41, the size of the cleaning module 4 in a specified radial direction can be reduced.

[0062] In one embodiment, if Figure 1 As shown, the base 1 includes two mounting plates 2, and all cleaning cores 42 are located between the two mounting plates 2. The two mounting plates 2 are respectively arranged on both sides of all elevator traction ropes 5. Figure 5 , Figure 6 , Figure 7 As shown, the horizontal length of the mounting plate 2 can be lengthened or shortened according to the number of elevator traction ropes 5.

[0063] The beneficial effect of adopting the above embodiment is that the mounting plate 2 provides a stable mounting position for the cleaning module 4 .

[0064] like Figure 5 , Figure 6 , Figure 7 As shown in a non-limiting example, the shape and size of the mounting plate 2 can be selected according to actual needs. Figure 5 and Figure 6 The mounting plate 2 in the figure can be arranged with two cleaning columns, Figure 7 The mounting plate 2 in the figure can be arranged with three cleaning rows.

[0065] like Figure 5 , Figure 6 , Figure 7 As shown, in a non-limiting example, the mounting plate 2 has a hollow window 21, and the upper and lower adjacent parts of the hollow window 21 are the crossbeams 22 of the mounting plate 2 for fixing the cleaning module 4. The design of the hollow window 21 is to make room for operation, so as to facilitate the disassembly and assembly of the cleaning modules 4 in the cleaning columns at different heights, and to make the mounting plate 2 lighter.

[0066] like Figure 8 As shown, in a non-limiting example, the two mounting plates 2 are fixed by a positioning pin 3, and the positioning pin 3 is a stepped shaft, which includes a middle section 31 and two side sections 32, and the diameter of the middle section 31 is larger than the diameter of the two side sections 32. The relatively thin two side sections 32 can be inserted into the mounting plate 2 to achieve fixation. In addition, the junction between the middle section 31 and the two side sections 32 plays a limiting role, which is convenient for controlling the two mounting plates 2 to be at a rated distance. The two side ends 32 can be formed with threads to connect with nuts.

[0067] like Figure 4 As shown, in a non-limiting example, the base 1 includes a bottom plate 11, a vertical column 12 is fixed on the top of the bottom plate 11, and a rib 13 is also fixed at the junction of the bottom plate 11 and the column 12 to ensure the stability of the connection between the bottom plate 11 and the column 12. The column is provided with a plurality of waist-shaped holes 14, and the mounting plate 2 is assembled with the base 1 by fasteners such as bolts passing through the waist-shaped holes 14, and the waist-shaped holes 14 allow the mounting plate 2 to have a certain vertical fine-tuning margin.

[0068] like Fig. 9 , Fig.10 , Fig.25 , Fig.26 As shown, in one embodiment, each bearing mechanism includes a plurality of rolling bodies, which may be balls, rollers, needle rollers, etc. From the perspective of shape, the roller 412 includes a roller and a needle roller, and the ratio of the axial length to the diameter of the roller is smaller than the ratio of the axial length to the diameter of the needle roller. Preferably, the roller 412 is provided on both sides of the cleaning core 42 facing the mounting plate 2, and the cleaning module 4 includes a bearing frame 411 assembled with the mounting plate 2. The roller 412 and the bearing frame 411 constitute an open bearing 41, and the roller 412 is exposed outside the bearing frame 411. Two open bearings 41 are symmetrically arranged on both sides of a cleaning core 42, and two open bearings 41 in contact with each other and a cleaning core 42 together constitute a cleaning module 4. Preferably, one side of each cleaning core 42 is in contact with three rollers 412, that is, each cleaning core 42 is in contact with a total of six rollers 412. The two open bearings 41 can cover a partial area of ​​the circumference of the cleaning core 42, for example, cover an area of ​​1 / 2 to 4 / 5 of the circumference of the cleaning core 42. In this way, the open bearings 41 can be guaranteed to hold and support the cleaning core 42, and a space can be left between the two open bearings 41, especially a space open toward the adjacent elevator traction rope 5.

[0069] The beneficial effects of the above embodiment are: the roller 412 can bear a greater axial force than the ball, and the roller 412 is thinner than the roller and occupies a smaller radial space. The bearing frame 411 is easy to fix with the mounting plate 2. The roller 412 and the bearing frame 411 constitute a bearing mechanism.

[0070] like Fig.25 As shown, in a non-limiting example, the bearing frame 411 is semi-open, and the edge extension lines on both sides of the bearing frame 411 point to the axis of the cleaning core 42. The angle between the edges on both sides of the bearing frame 411 is the expansion angle α. The angle of the expansion angle α is related to the width of the bearing frame 411, and the expansion angle α should not be too large.

[0071] The core of the expansion angle α is to control the size of the cleaning module 4 in a certain direction. Fig.25 As shown, it can also be limited from other aspects. In the arrangement direction of the cleaning cores 42 in the same cleaning row, the size of the cleaning module 4, that is, the bearing frame width L3, limiting the size of the bearing frame width L3 can also have a similar effect to limiting the expansion angle α, thereby ensuring that the cleaning module 4 has a narrower size and can adapt to the situation of elevator traction ropes 5 that are closely spaced.

[0072] In addition, the maximum outer diameter of the cleaning core 42 is the cleaning core outer diameter L2, and the minimum spacing between the rollers 412 on both sides is the roller spacing L1. In order to ensure that the plurality of rollers 412 can limit the cleaning core 42 they surround, the roller spacing L1 is smaller than the cleaning core outer diameter L2, so that the cleaning core 42 is not easy to loosen and separate from the rollers 412. However, the difference between the roller spacing L1 and the cleaning core outer diameter L2 cannot be too large. If it is too large, it means that the rollers 412 are arranged almost around the cleaning core 42, and the width of the cleaning module 4 will inevitably increase due to the existence of the rollers 412, resulting in the length-to-width ratio of the cleaning module 4 being close to one-to-one. If the difference between the roller spacing L1 and the cleaning core outer diameter L2 is small, it means that the rollers 412 are basically located on both sides of the cleaning core 42, and the length-to-width ratio of the cleaning module 4 is relatively large, which can ensure that the width of the cleaning module 4 is narrow.

[0073] In one non-limiting example, the spread angle α may be in the range of 90° to 120°.

[0074] like Fig.12 , Fig.26 As shown, in one embodiment, the roller 412 is arranged obliquely, that is, it is inclined relative to the elevator traction rope 5 or the vertical direction, and the roller 412 is arranged around the axis of the cleaning core 42. The vertical distance from the top of the roller 412 to the axis of the cleaning core 42 is greater than the vertical distance from the bottom of the roller 412 to the axis of the cleaning core 42.

[0075] The beneficial effect of the above embodiment is that compared with the vertical arrangement, the top of the roller 412 is extended outward as a whole, and the roller 412 arranged obliquely can provide sufficient vertical support force for the cleaning core 42 while ensuring rolling friction, so that the circumferential surface of the roller 412 bears part of the axial force of the cleaning core 42. Even if the cleaning core 42 is subjected to a large axial force when moving relative to the elevator traction rope 5, the cleaning core 42 is not easy to loosen. Figure 1 , Fig.26 As shown, when the elevator traction rope 5 moves downward, it will give the cleaning core 42 a downward force. At this time, the top and side of the roller 412 can give the cleaning core 42 an upward supporting force.

[0076] like Fig.12 , Fig. 22 As shown in a non-limiting example, the angle between the roller 412 and the plumb line is the installation angle, which is equal to the inclination angle β. The angle between the contact portion between the outer wall of the cleaning core 42 and the roller 412 and the plumb line is also equal to the inclination angle β. The two angles are the same, as shown in FIG. Fig.26 As shown, the surface of the roller 412 and the cleaning core 42 can fit tightly.

[0077] In a non-limiting example, the angle range of the inclination angle β can be 10° to 15°. Because the cleaning core 42 may have a large resistance and a large axial force when scraping off the sludge, the obliquely arranged roller 412 can withstand a large axial load and have a better cleaning effect. In actual application, when it is necessary to clean the surface of the elevator traction rope 5, the elevator traction rope cleaning device of the present application is sleeved on one end of the elevator traction rope 5, and the elevator traction rope 5 is allowed to move downward relative to the cleaning core 42. Relying on the unidirectional movement of the elevator traction rope 5 relative to the cleaning core 42, the cleaning core 42 cleans the sludge on the surface of the elevator traction rope 5. Under this force condition, the inclination angle β can provide a strong supporting force. When the elevator traction rope 5 moves upward in the opposite direction relative to the cleaning core 42, since the dirt such as sludge on the surface of the elevator traction rope 5 has been almost removed, the axial force on the cleaning core 42 is relatively small at this time.

[0078] In one embodiment, a pin 413 is mounted on the axis of the roller 412, and both ends of the pin 413 are mounted on the bearing frame 411. The specific forms of the roller 412 and the pin 413 can be various.

[0079] like Fig.14 , Fig.16 , Fig.18 As shown, in one embodiment, the roller 412 includes a first roller 4121 , both ends of the first roller 4121 are recessed with blind holes 41211 , and the pin 413 includes a first pin 4131 assembled with the blind holes 41211 .

[0080] The beneficial effect of the above embodiment is that when the two ends of the roller 412 are blind holes 41211, the two ends of the roller 412 are respectively provided with first pins 4131. The first roller 4121 is solid inside, and the overall structural strength is relatively large. At the same time, the end of the first pin 4131 contacts the bottom surface of the blind hole 41211, so the first roller 4121 and the first pin 4131 can withstand a relatively large axial force.

[0081] like Fig.15 , Fig.17 , Fig.19 As shown, in one embodiment, the roller 412 includes a second roller 4122, the second roller 4122 has an axially penetrating through hole 41221, and the pin 413 includes a second pin 4132 passing through the through hole 41221. Fig.15 As shown, the second pin shaft 4132 includes a flange portion 41321 extending radially outward, and the flange portion 41321 is in contact with the bottom axial end of the second roller 4122 .

[0082] The beneficial effect of adopting the above embodiment is that the flange portion 41321 supports the bottom axial end of the second roller 4122, so that the second roller 4122 and the second pin 4132 can also withstand a larger axial force.

[0083] like Fig.10 As shown, in a non-limiting example, the bearing frame 411 semi-encloses the roller 412 , and the top and bottom of the bearing frame 411 are provided with flanges 4111 extending in the same direction, and the ends of the pins 413 are assembled with the flanges 4111 .

[0084] like Fig. 22 As shown, in one embodiment, the overall shape of the outer wall of the cleaning core 42 is similar to a truncated cone with a larger top and a smaller bottom. Both ends of the cleaning core 42 are provided with limiting edges extending radially outward, namely, an upper limiting edge 4212 at the top of the cleaning core 42 and a lower limiting edge 4213 at the bottom of the cleaning core 42. A relatively concave slot 421 is formed between the upper limiting edge 4212 and the lower limiting edge 4213. The slot 421 can be movably assembled with the roller 412. The bottom surface of the slot 421 is an oblique conical surface 4211, and the oblique conical surface 4211 contacts the circumferential surface of the roller 412.

[0085] The beneficial effect of adopting the above embodiment is that the upper limit edge 4212 and the lower limit edge 4213 can further limit the axial freedom of the roller 412, and further prevent the cleaning core 42 from loosening during use.

[0086] like Fig. 22 As shown, in a non-limiting example, the junction of the upper limit edge 4212 and the oblique cone surface 4211 is provided with an inwardly concave upper groove 4214, and the junction of the lower limit edge 4213 and the oblique cone surface 4211 is provided with an inwardly concave lower groove 4215. The upper groove 4214 and the lower groove 4215 cancel the original right-angle inner angle here, and change it into a structure similar to an inner fillet, which can reduce local stress, and also avoid excessive friction between the edge of the roller 412 and the cleaning core 42, which can reduce the resistance of the roller 412 and the cleaning core 42 during rotation.

[0087] In one embodiment, the cleaning core 42 is composed of a plurality of detachable petals.

[0088] The beneficial effects of the above embodiment are as follows: the cleaning core 42 is not an integrated type, which facilitates the disassembly and assembly between the cleaning core 42 and the elevator traction rope 5. The cleaning core 42 composed of a plurality of petals has a compact overall structure, and the cleaning core 42 has an upper limit edge 4212 and a lower limit edge 4213 radially protruding at both ends, and the upper limit edge 4212 and the lower limit edge 4213 can contact and limit at both ends of the roller 412, so even if the petals of the cleaning core 42 are subjected to a large axial force during the cleaning process, the petals of the cleaning core 42 are still not easy to separate.

[0089] like Fig.23 , Fig.24 As shown, in a non-limiting example, the cleaning core 42 is split from the middle into two parts, namely, a first flap 425 and a second flap 426, and the two parts can be connected by a mortise and tenon structure. The first flap 425 is provided with a first tenon 4251 at the upper end and a first mortise 4252 at the lower end, and the second flap 426 is provided with a second mortise 4262 at the upper end and a second tenon 4261 at the lower end. The first tenon 4251 at the upper end of the first flap 425 is combined with the second mortise 4262 at the upper end of the second flap 426, and the first mortise 4252 at the lower end of the first flap 425 is combined with the second tenon 4261 at the lower end of the second flap 426. The mortise and tenon structure is firm and tight, and the cleaning core 42 is not easy to loosen during the rotation process. The connection between the tenons and mortise of the first flap 425 and the second flap 426 can be achieved by the axial relative movement of the first flap 425 and the second flap 426. After the connection, the mortise and tenon structure can prevent the first flap 425 and the second flap 426 from being separated in the radial direction of the cleaning core 42. Among them, the first tenon 4251 and the second tenon 4261 can both be dovetail tenons.

[0090] In one embodiment, if Fig.21 As shown, tooth tops 422 are also formed between adjacent tooth grooves 423, that is, the inner wall of the cleaning core 42 is alternately arranged with tooth tops 422 and tooth grooves 423. The spiral structure of the tooth tops 422 and tooth grooves 423 on the inner wall of the cleaning core 42 is concave and convex to the outer structure of the elevator traction rope 5. The spiral angle of the tooth tops 422 and tooth grooves 423 is the same as the spiral angle of the rope strands 51 in the twisted elevator traction rope 5, so that the inner wall of the cleaning core 42 can fit closely with the outer wall of the elevator traction rope 5, and can fully achieve surface contact, thereby effectively removing the oil sludge on the surface of the elevator traction rope 5.

[0091] like Fig. 20 As shown, in one embodiment, both ends of the roller 412 of the open bearing 41 have convex surfaces 412a, that is, the axial length of the roller 412 increases as it moves toward the axis of the roller 412 along the radial direction.

[0092] The beneficial effects of adopting the above embodiment are: Fig.26As shown, the convex surface 412a can reduce the contact area between the shaft end of the roller 412 and the cleaning core 42, thereby reducing the resistance of the cleaning core 42 during the rotation process.

[0093] In one embodiment, the number of tooth grooves 423 is equal to the number of strands of the elevator traction rope 5 .

[0094] The beneficial effect of adopting the above embodiment is that the number of tooth tops 422 and tooth grooves 423 is equal, and the number of tooth tops 422 or tooth grooves 423 is also consistent with the number of strands of the elevator traction rope, ensuring that the grooves between each adjacent rope strand 51 are embedded by tooth tops 422.

[0095] In one embodiment, the inner wall of the tooth groove 423 is a concave surface in contact with the outer wall of the rope strand 51 , and the radius of the cross-sectional profile of the inner wall of the tooth groove 423 matches the diameter of the rope strand 51 of the elevator traction rope 5 .

[0096] like Fig. 22 As shown, in one embodiment, the axial height of the cleaning core 42 gradually decreases in the radial outward direction. The height of the top of the cleaning core 42 gradually decreases. The top axial end of the cleaning core 42 forms a conical top surface 424, that is, the generatrix of the top surface of the cleaning core 42 is at a certain angle to the horizontal plane, that is, the positive angle at the junction of the top surface of the cleaning core 42 and the through cavity of the cleaning core 42 is an acute angle.

[0097] The beneficial effect of adopting the above embodiment is that compared with the conventional right-angled positive angle, the conical top surface 424 makes the positive angle sharper, which can play a similar effect as a plow when scraping the sludge on the surface of the elevator traction rope 5, reducing the resistance when scraping the sludge and improving the efficiency of cleaning the sludge.

[0098] In one embodiment, the cleaning core 42 can be made of a non-metal material with high hardness, low friction coefficient and strong wear resistance, or a metal material with relatively low hardness to avoid scratching the elevator traction rope 5 during use.

[0099] In one embodiment, the elevator traction rope 5 may be a steel wire rope. The steel wire rope has a rope core at its axis, and a plurality of rope strands 51 are spirally wound around the rope core.

[0100] In a practical application case, the elevator traction rope cleaning device of the present application includes a base 1, a mounting plate 2, a positioning pin 3, and a cleaning module 4. The base 1 can be fixed to the ground or installed on a mechanical component near the elevator traction rope 5. The mounting plate 2 is mounted on the base 1 by bolts. The two ends of the positioning pin 3 are respectively connected to two mounting plates 2, and the two mounting plates 2 are respectively arranged on both sides of all elevator traction ropes 5, and the two sides of the cleaning module 4 are respectively assembled with the mounting plates 2 on both sides. The inner wall of the cleaning module 4 has a spiral tooth structure, which matches the spiral shape structure of the elevator traction rope 5, and the cleaning module 4 can wrap the elevator traction rope 5 along the circumferential direction. The cleaning modules 4 of two adjacent elevator traction ropes 5 are not on the same horizontal plane, and the cleaning module 4 can use the horizontal spacing of adjacent elevator traction ropes 5 to control it within 3mm to 8mm.

[0101] On the other hand, the present application also provides an elevator, which adopts the above-mentioned elevator traction rope cleaning device.

[0102] The elevator includes at least a car and a traction mechanism. When the traction machine drives the elevator traction rope 5 to move, under the action of the spiral structures of the elevator traction rope 5 and the cleaning module 4, the elevator traction rope 5 moving relatively axially will drive the cleaning core 42 of the cleaning module 4 to rotate, and the cleaning module 4 will remove dirt such as sludge on the surface of the elevator traction rope 5 through the tooth top 422 and the tooth groove 423, thereby cleaning the surface of the elevator traction rope 5 and effectively extending the service life of the elevator traction rope 5.

[0103] The above embodiments are only for illustrating the technical concept and features of the present application, and their purpose is to enable people familiar with this technology to understand the content of the present application and implement it. They cannot be used to limit the scope of protection of the present application. All equivalent changes or modifications made according to the spirit of the present application should be included in the scope of protection of the present application.
