Description

Technical Field

[0001] The present invention relates to the technical field of traction sheave cleaning, and more particularly to a traction sheave anti-pollution treatment system for a traction elevator. Background Art

[0002] The elevator traction system's function is to output and transmit power to drive the elevator. It primarily consists of a traction machine, traction ropes, a guide pulley, and a return pulley. The traction machine, which provides power for the elevator, comprises an electric motor, a traction sheave, a coupling, a reduction gearbox, and an electromagnetic brake. The traction ropes are connected to the car and counterweight at either end, respectively. Friction between the ropes and the traction sheave drives the car upwards and downwards. Regular maintenance of the traction sheave and ropes is crucial throughout the elevator's operation.

[0003] During operation, the traction rope is always in a running state. At this time, the contact area between the traction rope and the air is very large. The dust and dirt in the air will adhere to the surface of the traction rope. During the rotation of the traction wheel, the impurities attached to the surface of the traction rope will cover the surface of the traction wheel groove. If these impurities are not cleaned in time, these impurities will agglomerate after being squeezed by the traction rope for a long time, thereby accelerating the corrosion and wear of the traction rope and traction wheel, and causing the traction rope to slip, affecting the operation of the traction rope.

[0035] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] See also Figure 1-9 , the present invention provides the following technical solutions:

[0038] Specifically, it refers to a traction sheave anti-pollution treatment system for a traction elevator, including a traction machine 1 and multiple traction ropes 4. The output end of the traction machine 1 is provided with a sheave 2, and multiple rope grooves 3 are opened on the sheave 2. The traction rope 4 is laid on the upper side of the rope groove 3. When in use, the traction machine 1 is started, and the output shaft synchronously drives the sheave 2 to rotate, thereby transmitting the traction rope 4.

[0039] Furthermore, a plurality of first rotating grooves 31 arranged in a circumferential array are provided on the inner wall of the rope groove 3, a plurality of second rotating grooves 38 arranged in a circumferential array are provided on the inner wall of the rope groove 3, the second rotating groove 38 is provided between the two first rotating grooves 31, and is communicated with the two first rotating grooves 31 on both sides, a first rotating shaft 33 is rotatably connected in the first rotating groove 31, the outer surface of the first rotating shaft 33 is provided with a first arc plate 32 adapted to the first rotating groove 31, and a second arc plate 37 is provided in the second rotating groove 38. When the first arc plate 37 is rotated, the first rotating shaft 33 is rotated. When the plate 32 rotates into the first rotation groove 31 and the second curved plate 37 rotates into the second rotation groove 38, the outer surfaces of the multiple first curved plates 32 and the second curved plates 37 are combined into a circle. When the traction rope 4 is laid on the upper side of the rope groove 3, the traction rope 4 contacts the outer surfaces of the first curved plates 32 and the second curved plates 37. When the first curved plate 32 rotates to the lower side of the rope groove 3, the first curved plate 32 contacts the traction rope 4, so that the first curved plate 32 can rotate outward with the first rotation axis 33 as the rotation point under the action of inertia.

[0040] In the present invention, the first rotating shaft 33 is arranged on one side of the rotation direction of the pulley 2, so that when the pulley 2 rotates, the first curved plate 32 rotates with the pulley 2. When the first curved plate 32 rotates to contact the traction rope 4, the traction rope 4 will squeeze the first curved plate 32, causing the first curved plate 32 to rotate toward one side in the first rotating groove 31 until the first curved plate 32 is completely rotated into the first rotating groove 31.

[0041] In the present invention, the outer surfaces of the first curved plate 32 and the second curved plate 37 are both provided with friction layers for increasing the friction between the first curved plate 32 and the second curved plate 37 and the traction rope 4 .

[0042] Furthermore, a torsion spring is provided between the first rotating shaft 33 and the inner wall of the first rotating groove 31, so that the first curved plate 32 is initially in an outwardly rotated state under the action of the torsion spring. In this way, when the first curved plate 32 is no longer in contact with the first rotating groove 31, the torsion spring ensures that the first curved plate 32 rotates out. At the same time, the first curved plate 32 is restricted by the torsion spring, and the problem of impurities on the curved surface of the first curved plate 32 rotating when being scraped off is avoided as much as possible.

[0043] Furthermore, a movable groove 35 is provided on the inner wall of the first rotating groove 31, and a wiping block 34 is slidably connected in the movable groove 35. A first spring 36 is provided between the wiping block 34 and the inner wall of the movable groove 35. When the first spring 36 is not squeezed, the first spring 36 will form a thrust on the wiping block 34 and push one side of the wiping block 34 out of the movable groove 35 and extend out of the first rotating groove 31. An extension groove 310 connected to the first rotating groove 31 is provided on the inner wall of the second rotating groove 38 near the wiping block 34, and a second rotating shaft 311 is rotatably connected in the extension groove 310. A rotating seat 39 is provided on the surface of the second curved plate 37 near the extension groove 310. The rotating seat 39 extends into the extension groove 310 and is sleeved on the outer surface of the second rotating shaft 311. An auxiliary rotating component for controlling the rotation of the second curved plate 37 is provided on the second rotating shaft 311.

[0044] When in use, the auxiliary rotating assembly controls the rotation of the rotating seat 39, so that the second curved plate 37 rotates outward and rotates into the first rotating groove 31. At this time, the first spring 36 pushes the wiping block 34 to move out of the movable groove 35. At this time, the wiping block 34 is close to a corner of the second curved plate 37 and contacts the outer surface of the second curved plate 37, so that the wiping block 34 can scrape off impurities attached to the outer surface of the second curved plate 37. Since the first curved plate 32 rotates outward, it rotates to the lower side of the sheave 2 and does not contact the traction rope 4. Therefore, the scraped impurities fall downward under the action of inertia.

[0045] The auxiliary rotating assembly includes a worm gear 314, which is sleeved on the outer surface of the second rotating shaft 311. A worm 315 is meshedly connected to one side of the worm gear 314. A movable cavity 312 is provided inside the rope pulley 2 near the extension groove 310. A movable shaft 313 is provided on the surface of the worm 315 facing the movable cavity 312. The other end of the movable shaft 313 rotates and passes through the movable cavity 312. A twisted rod 316 is provided in the movable cavity 312. A twisted groove 317 threadedly sleeved on the outer surface of the twisted rod 316 is provided on the surface of the movable shaft 313 away from the worm 315.

[0046] When in use, it is only necessary to control the up and down displacement of the twisted rod 316, so that the movable shaft 313 rotates under the drive of the spiral texture of the twisted rod 316. At this time, the worm 315 rotates synchronously with the movable shaft 313, so the engagement drives the worm wheel 314 to rotate, and the second rotating shaft 311 can synchronously drive the second curved plate 37 to rotate. At the same time, since the worm gear transmission has a self-locking effect, when the wiping block 34 scrapes impurities on the outer surface of the second curved plate 37, the second curved plate 37 will not rotate, ensuring the cleaning effect of impurities on the outer surface of the second curved plate 37.

[0047] Furthermore, a movable rod 318 is provided in the movable chamber 312, and the other end of the movable rod 318 slides through the movable groove 35. The outer surface of the movable rod 318 located in the movable chamber 312 is sleeved with a limiting plate, and a first tension spring 320 that is movably sleeved on the outer surface of the movable rod 318 is provided between the limiting plate and the inner wall of the movable chamber 312. A first rotating plate 319 is hinged between one end of the movable rod 318 located in the movable chamber 312 and the twisted rod 316. A lifting groove 321 is provided on the surface of the wiping block 34 near the movable rod 318, and one end of the movable rod 318 located in the movable groove 35 extends into the lifting groove 321, A lifting block 322 in the shape of a right-angled trapezoid is provided on the inner wall of the lifting groove 321 facing the movable rod 318, and one end of the movable rod 318 located in the lifting groove 321 is hinged with a first contact rod 3181, and the other end of the first contact rod 3181 contacts the inner wall of the lifting groove 321, the inclined surface and the vertical surface of the lifting block 322 respectively, and slides. A torsion spring is also provided between the first contact rod 3181 and the movable rod 318. Under the action of the torsion spring, the first contact rod 3181 remains horizontal with the movable rod 318, and a blocking plate 3182 is provided on the lower side of the movable rod 318 to prevent the first contact rod 3181 from rotating downward.

[0048] When the wiping block 34 is retracted into the movable groove 35, the first contact rod 3181 contacts the inner wall of the lifting groove 321. When the wiping block 34 is pushed out by the first spring 36, the first contact rod 3181 slides along the inner wall of the lifting groove 321. When the first contact rod 3181 slides to the inclined surface of the lifting block 322, the first contact rod 3181 is blocked by the blocking plate 3182 and cannot rotate. As a result, the inclined surface of the lifting block 322 squeezes the first contact rod 3181, causing the first contact rod 3181 to push the movable rod 318 into the movable cavity 312. At the same time, the first tension spring 320 is stressed and stretched. At this time, the first rotating The plate 319 forms a thrust on the twist rod 316, causing the twist rod 316 to move downward in the twist groove 317, thereby driving the movable shaft 313 to rotate, so that the second curved plate 37 rotates outward. When the first contact rod 3181 slides to the vertical surface of the lifting block 322 and contacts, the second curved plate 37 rotates vertically, and a corner of the wiping block 34 can scrape impurities on the outer surface of the second curved plate 37. When the wiping block 34 continues to move downward, the first contact rod 3181 slides on the vertical surface of the lifting block 322. When the wiping block 34 finishes scraping the outer surface of the second curved plate 37, the first contact rod 3181 slides to the lifting groove 3 When the first curved plate 32 rotates toward one side in the first rotating groove 31, the first curved plate 32 first contacts the wiping block 34. At this time, the first curved plate 32 squeezes the wiping block 34, causing the wiping block 34 to move into the movable groove 35. At this time, the outer surface of the lifting block 322 will form an upward thrust on the first contact rod 3181, Since the blocking plate 3182 only blocks the downward rotation of the first contact rod 3181, the first contact rod 3181 rotates upward. At this time, the movable rod 318 loses its restriction and moves toward the side close to the movable groove 35 under the pull of the first tension spring 320. At this time, the first rotating plate 319 pulls the twisted rod 316 to move upward, thereby driving the movable shaft 313 to rotate in the opposite direction, so that the second curved plate 37 rotates into the second rotating groove 38. In this way, when the first curved plate 32 rotates into the first rotating groove 31, the second curved plate 37 will not affect the rotation of the first curved plate 32, ensuring the smoothness of the first curved plate 32 when it is reset.

[0049] Furthermore, a contraction groove 5 is provided on the inner wall of the second rotating groove 38, and a cleaning component is provided in the contraction groove 5 for scraping impurities on the outer surface of the first curved plate 32. The cleaning component includes a contraction plate 51, and the contraction plate 51 slides in the contraction groove 5. A tooth plate cavity 53 is provided on the side of the contraction groove 5 close to the second rotating groove 38. A first gear 54 is rotatably connected in the tooth plate cavity 53, and the upper and lower sides of the first gear 54 are respectively meshed with the first tooth plate 55 and the second tooth plate 510. The second tooth plate 510 slides toward one side of the first curved plate 32 and penetrates the outer surface of the contraction plate 51. A retractable scraping head is provided on the side of the second tooth plate 510 outside the contraction plate 51, and impurities on the outer surface of the first curved plate 32 are scraped off by the retractable scraping head. The first tooth plate 55 slides toward one side of the rotating seat 39 and penetrates the contraction plate 51. On the outer surface of the plate 51, an extrusion inclined groove 59 communicating with the contraction groove 5 is provided on the inner wall of the second rotating groove 38. The first tooth plate 55 is located on one side outside the second rotating groove 38 and contacts the inclined surface of the extrusion inclined groove 59 and slides. A fixing rod 56 is provided on the inner wall of the tooth plate cavity 53 facing the first tooth plate 55. The inner wall of the first tooth plate 55 is hollow, and the end of the fixing rod 56 away from the fixed point slides into the first tooth plate 55. The end of the fixing rod 56 located in the first tooth plate 55 is provided with a built-in plate 57 sliding inside the first tooth plate 55. A second tension spring 58 movably sleeved on the outer surface of the fixing rod 56 is provided between the built-in plate 57 and the inner wall of the first tooth plate 55. When the second tension spring 58 is not pulled, it will form a pulling force on the built-in plate 57, so that the initial position of one side of the first tooth plate 55 is to extend the contraction plate 51.

[0050] When the retraction plate 51 is fully retracted into the retraction groove 5, the first tooth plate 55 and the second tooth plate 510 are retracted into the tooth plate cavity 53, and the second tension spring 58 is in a stretched state. When the retraction plate 51 extends out of the retraction groove 5, the first tooth plate 55 slides to the extrusion inclined groove 59. At this time, the second tension spring 58 loses its extrusion and pulls the first tooth plate 55 to move outward. During the displacement of the first tooth plate 55, the engagement drives the first gear 54 to rotate. At this time, the first gear 54 forms a thrust on the second tooth plate 510 on its lower side, thereby pushing the second tooth plate 510 out of the retraction plate 51. At the same time, the retractable scraper head contacts the outer surface of the first curved plate 32. When the retraction plate 51 is extended out of the retraction groove 5, the first tooth plate 55 slides to the extrusion inclined groove 59. At this time, the second tension spring 58 loses its extrusion and pulls the first tooth plate 55 to move outward. When the contraction plate 51 is retracted into the contraction groove 5, the first tooth plate 55 first contacts the inclined surface of the extrusion inclined groove 59. When the contraction plate 51 continues to move into the contraction groove 5, the inclined surface of the extrusion inclined groove 59 will squeeze the first tooth plate 55, so that the first tooth plate 55 gradually moves into the tooth plate cavity 53, and the second tooth plate 510 also moves into the tooth plate cavity 53 under the meshing transmission of the first gear 54. When the contraction plate 51 is completely moved into the contraction groove 5, one side of the first tooth plate 55 is squeezed against the inner wall of the contraction groove 5, so that the second tooth plate 510 and the retractable scraper head are moved into the tooth plate cavity 53, so that the contraction plate 51 will not be blocked from moving into the contraction groove 5.

[0051] Furthermore, the retractable scraping head includes a scraper 511, which contacts the outer surface of the first curved plate 32. The interior of the second tooth plate 510 is hollow. A retraction rod 512 is provided on the surface of the scraper 511 facing the second tooth plate 510. The other end of the retraction rod 512 slides through the second tooth plate 510. A second spring 513 is provided between the retraction rod 512 and the inner wall of the second tooth plate 510. When the second spring 513 is not squeezed, the second spring 513 will form a thrust on the retraction rod 512, so that the scraper 511 is located on the side away from the second tooth plate 510.

[0052] In the present invention, if the scraper 511 is initially positioned on a side away from the second tooth plate 510, it is easy for the scraper 511 to be unable to move into the tooth plate cavity 53 as the second tooth plate 510 moves. To this end, a gear groove 514 is provided on the lower surface of the second tooth plate 510 and is connected to its interior. A second gear 515 is rotatably connected in the gear groove 514, and the upper side of the second gear 515 extends into the second tooth plate 510. A tooth groove is provided on the lower surface of the retraction rod 512 and is meshed with the second gear 515. The lower side of the second gear 515 extends out of the lower surface of the second tooth plate 510. A plurality of continuously arranged retraction teeth 516 are provided on the bottom wall of the tooth plate cavity 53. When the second tooth plate 510 moves into the tooth plate cavity 53, the lower side of the second gear 515 is meshed with the plurality of retraction teeth 516.

[0053] When in use, when the second tooth plate 510 moves toward the outside of the retracting plate 51, since the lower side of the second gear 515 is meshed with the plurality of retracting teeth 516, the second gear 515 moves synchronously with the second tooth plate 510, and the second gear 515 rotates clockwise under the meshing transmission of the retracting teeth 516. The second gear 515 generates a thrust on the retracting rod 512, so that the retracting rod 512 pushes the scraper 511 to move to the side away from the second tooth plate 510. At the same time, the second spring 513 loses its compression and stretches. When one side of the second toothed plate 510 is completely displaced out of the retracting plate 51, the second gear 515 is separated from the retracting tooth 516. At this time, the scraper 511 contacts the outer surface of the first curved plate 32. At the same time, the second spring 513 is not stretched to the initial position. Therefore, when the retracting plate 51 is displaced outward, the scraper 511 scrapes along the outer surface of the first curved plate 32. Since the outer surface of the first curved plate 32 has a certain curvature, the second spring 513 will generate a thrust on the retracting rod 512 during the displacement of the scraper 511. The scraper 511 can always scrape the outer surface of the first curved plate 32. The above structure can timely scrape off the impurities attached to the outer surface of the first curved plate 32 without the need for additional external auxiliary cleaning devices, and avoids as much impurities as possible adhering to the rope groove 3, which accelerates the corrosion of the traction rope 4 and the rope wheel 2, and prevents the traction rope 4 and the rope wheel 2 from slipping, thereby ensuring the stability of the traction elevator operation. When the retracting plate 51 is reset, the second tooth plate 510 moves into the tooth plate cavity 53. At this time, the second tooth plate 510 is moved into the tooth plate cavity 53. The wheel 515 is engaged with the retraction teeth 516, so that when the second tooth plate 510 is displaced into the tooth plate cavity 53, the second gear 515 rotates counterclockwise under the meshing transmission of the retraction teeth 516, so that the second gear 515 can pull the retraction rod 512 to move toward one side of the second tooth plate 510, and the scraper 511 is displaced toward the side close to the second tooth plate 510. At the same time, the second spring 513 contracts until the scraper 511 is also retracted into the tooth plate cavity 53, so that the scraper 511 will not hinder the retraction of the retraction plate 51.

[0054] A push plate 52 is provided on the side of the retracting plate 51 away from the second rotating groove 38. The interior of the push plate 52 is hollow. A push rod 518 is provided on the surface of the retracting plate 51 close to the push plate 52. The other end of the push rod 518 slides through the push plate 52. A mounting plate 519 is provided on the end of the push rod 518 located in the push plate 52. A third spring 520 movably sleeved on the outer surface of the push rod 518 is provided between the mounting plate 519 and the bottom wall of the push plate 52. When the third spring 520 is not squeezed, the third spring 520 will form a thrust on the mounting plate 519, so that the retracting plate The initial position of 51 is close to the push plate 52, and a second contact rod 521 is provided in the push plate 52. A second rotating plate 517 is hinged between one end of the second contact rod 521 and the mounting plate 519. A shaking groove 522 is provided on the inner wall of the contraction groove 5. The other end of the second contact rod 521 slides through the outer surface of the contraction plate 51 and extends into the shaking groove 522. A plurality of shaking protrusions 523 arranged at intervals are provided on the inner wall of the shaking groove 522. One end of the second contact rod 521 located in the shaking groove 522 contacts the outer surface of the shaking protrusion 523 and slides.

[0055] When in use, the retracting plate 51 extends out of the retracting groove 5, and the second contact rod 521 slides in the shaking groove 522. When the scraper 511 contacts the outer surface of the first curved plate 32, the second contact rod 521 slides to the side close to the shaking protrusion 523. When the retracting plate 51 continues to move outward, the second contact rod 521 contacts the shaking protrusion 523, and the shaking protrusion 523 forms a thrust on the second contact rod 521, causing the second contact rod 521 to move toward the side toward the inside of the push plate 52. The second contact rod 521 forms a thrust on the second rotating plate 517, and the second rotating plate 5 17 pushes the mounting plate 519 to move downward, and at the same time, the third spring 520 is stressed and contracts, and the retraction plate 51 moves to the side away from the push plate 52. When the second contact rod 521 slides out of the shaking protrusion 523, the third spring 520 pushes the retraction plate 51 to move to the side close to the push plate 52. Since multiple shaking protrusions 523 are provided, the scraper 511 can be controlled to move back and forth when the retraction plate 51 moves out of the retraction groove 5, thereby further improving the scraping effect of impurities on the outer surface of the first curved plate 32 and ensuring the cleanliness of the outer surface of the first curved plate 32.

[0056] A plurality of control cavities 6 arranged in a circumferential array are provided in the rope pulley 2, and the control cavities 6 are communicated with the contraction groove 5. A third contact rod 61 is provided in the control cavity 6, and a third rotating plate 62 is hinged on the surface of the third contact rod 61 facing the contraction groove 5. The other side of the third rotating plate 62 extends into the contraction groove 5 and is hinged to the upper surface of the push plate 52. The other end of the third contact rod 61 slides through the right side surface of the rope pulley 2, and a sleeve plate 63 is sleeved on the outer surface of the end of the third contact rod 61 outside the rope pulley 2. A fourth spring 64 movably sleeved on the outer surface of the third contact rod 61 is provided between the sleeve plate 63 and the outer surface of the rope pulley 2. When the fourth spring 64 is not squeezed, the fourth spring 64 will form a thrust on the sleeve plate 63, so that the third rotating plate 62 pulls the contraction plate 51 to contract into the contraction groove 5.

[0057] A collecting plate 7 is provided on the right side surface of the traction machine 1 shell. The collecting plate 7 is located directly below the sheave 2 and is used to collect scraped impurities. A fixing plate 8 is provided on the upper surface of the collecting plate 7. The fixing plate 8 is located on the right side of the sheave 2. An isosceles triangle extrusion block 81 is provided on the surface of the fixing plate 8 facing the sheave 2. The third contact rod 61 rotates to the bottom of the sheave 2. The end of the third contact rod 61 located outside the sheave 2 contacts the inclined surface of the extrusion block 81. The oblique surface of the extrusion block 81 squeezes the third contact rod 61, causing the third contact rod 61 to move into the control chamber 6. At the same time, the fourth spring 64 is stressed and contracts. At the same time, the third rotating plate 62 forms a thrust on the contraction plate 51, thereby pushing the contraction plate 51 out of the contraction groove 5.
