[0035] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0036] The embodiments of the present invention are:

[0037] refer to Figures 1 to 8 As shown, an elevator traction sheave rope groove oil sludge removal device includes a frame, a traction machine 1, a traction sheave 2, a first speed reducer 3, a steel rope 4, and a cleaning mechanism 5. The traction sheave 2 is rotatably mounted on the frame. The traction sheave 2 has at least two rope grooves 21, specifically six rope grooves 21. A partition 22 is formed between two adjacent rope grooves 21. The steel rope 4 is disposed in the rope grooves 21. The traction machine 1 is connected to the traction sheave 2 via the first speed reducer 3. The cleaning mechanism 5 is disposed on the frame and distributed on the lower side of the traction sheave 2 to clean the oil sludge in the rope grooves 21 of the traction sheave 2.

[0038] The cleaning mechanism 5 includes a driving motor 51, a second reducer 52, a rotating shaft 53, a first sliding sleeve 54, a moving box 55, a first bearing 56, a reversing assembly 57, a cleaning connecting plate 58 and a cleaning assembly 59. The rotating shaft 53 is rotatably arranged on the frame and distributed along the axial direction of the traction wheel 2. The outer surface of the rotating shaft 53 is provided with a first ridge 531 distributed along its axial direction. The driving motor 51 is connected to the rotating shaft 53 through the second reducer 52. The first sliding sleeve 54 is rotatably sleeved on the rotating shaft 53. The inner surface of the first sliding sleeve 54 is provided with a first ridge 531 distributed along its axial direction. A first slide groove 541 is provided to cooperate with the first protrusion 531. The movable box 55 is provided on the first sliding sleeve 54 through a first bearing 56. The reversing assembly 57 is provided on the movable box 55 and the frame. The reversing assembly 57 causes the movable box 55 to reciprocate along the axial direction of the rotating shaft 53. One end of the cleaning connecting plate 58 is provided on the movable box 55. The cleaning assembly 59 is provided at the other end of the cleaning connecting plate 58. The movable box 55 reciprocates along the axial direction of the rotating shaft 53, so that the cleaning assembly 59 cleans each rope groove 21 of the traction sheave 2 in sequence along the axial direction of the traction sheave 2.

[0039] The cleaning assembly 59 includes a support rod 591, a rotating ball 592, a second bearing 593, two mounting plates 594, two flexible support plates 595, a first cleaning plate 596 and a second cleaning plate 597. One end of the support rod 591 is arranged on the cleaning connecting plate 58, and the rotating ball 592 is rotatably arranged on the other end of the support rod 591 through the second bearing 593. The two mounting plates 594 are axially symmetrically distributed on the rotating ball 592. The two mounting plates 594 are in a "V" shape. The two flexible support plates 59 5 are respectively provided on the mounting plates 594, and the first cleaning plate 596 and the second cleaning plate 597 are respectively provided on two flexible support plates 595. When cleaning the first rope groove 21 of the traction sheave 2, the first cleaning plate 596 is embedded in the first rope groove 21, and the second cleaning plate 597 is distributed outside the first rope groove 21. The moving box 55 is moved one station along the axial direction of the rotating shaft 53, and the second cleaning plate 597 is embedded in the second rope groove 21, and the first cleaning plate 596 is distributed outside the second rope groove 21.

[0040] The traction sheave rope groove sludge cleaning device of the present elevator, the traction machine 1 drives the traction sheave 2 to rotate through the first reducer 3, and drives the wire rope 4 to move through the friction between the traction sheave 2 and the wire rope 4. At the same time, the driving motor 51 drives the rotating shaft 53 to rotate through the second reducer 52, thereby driving the first sliding sleeve 54 to rotate, so that the moving box 55 moves along the axial direction of the rotating shaft 53, and the reversing component 57 makes the moving box 55 reciprocate. The cleaning component 59 on the moving box 55 cleans each rope groove 21 of the traction sheave 2 in turn along the axial direction of the traction sheave 2. In this way, the cleaning component 59 forms regular interval contact with each rope groove 21 on the traction sheave 2, ensuring that the traction sheave 2 rotates while the sludge in the single rope groove 21 is cleaned, and the contact time between the traction sheave 2 and the traction sheave 2 during operation is reduced, thereby improving the service life of the cleaning component 59 and ensuring the Cleaning efficiency; specifically, when cleaning the first rope groove 21 of the traction sheave 2, the first cleaning plate 596 is embedded in the first rope groove 21, and the second cleaning plate 597 is distributed on the outside of the first rope groove 21. The movable box 55 moves one station along the axial direction of the rotating shaft 53, and the second cleaning plate 597 is embedded in the second rope groove 21. The first cleaning plate 596 is distributed on the outside of the second rope groove 21. Therefore, during the movement of the movable box 55 along the axial direction of the traction sheave 2, the first cleaning plate 596 and the second cleaning plate 597 are sequentially embedded in the rope groove 21 of the traction sheave 2, and the operation of the drive motor 51 is stopped intermittently. The length of the intermittent time is the number of rotations of the traction sheave 2, so that the first cleaning plate 596 or the second cleaning plate 597 can clean the oil sludge inside the rope groove 21 after being embedded in the rope groove 21. It is convenient to use, durable, and has low cost.

[0041] Specifically, the reversing assembly 57 includes a first bevel gear 571, a second bevel gear 572, a third bevel gear 573, a gear 574, a rack 575, a connecting shaft 576, a shift rod 577, a second sleeve 578, a reversing sleeve 579 and two limiters 580. The second sleeve 578 is slidably arranged on the first sleeve 54. A second ridge 542 is provided on the outer surface of the first sleeve 54 along its axial direction. A second slide groove 543 is provided on the inner surface of the second sleeve 578 that cooperates with the second ridge 542. The first bevel gear 571 and the second bevel gear 572 are axially symmetrically arranged on the second sleeve 578 respectively. The reversing sleeve 579 is sleeved on the second sleeve 578 and is divided into two parts. It is arranged between the first bevel gear 571 and the second bevel gear 572, one end of the shift rod 577 is connected to the reversing sleeve 579, one end of the shift rod 577 extends out of the moving box 55, the rack 575 is provided on the frame, and is distributed along the axial direction of the traction wheel 2, the connecting shaft 576 is rotatably provided on the moving box 55, the gear 574 is provided at the outer end of the connecting shaft 576, and is meshed with the rack 575, the third bevel gear 573 is provided at the other end of the connecting shaft 576, and the reversing of the moving box 55 is realized by meshing the third bevel gear 573 with the first bevel gear 571 or the second bevel gear 572. The two limit members 580 are provided on the frame and distributed on both sides of the axial direction of the traction wheel 2.

[0042] The working principle of the reversing assembly is as follows: the driving motor 51 drives the rotating shaft 53 to rotate, thereby driving the first sliding sleeve 54 to rotate, and the first sliding sleeve 54 drives the second sliding sleeve 578, the first bevel gear 571 and the second bevel gear 572 to rotate. When the first bevel gear 571 and the third bevel gear 573 are meshed and transmitted, the connecting shaft and the gear are driven to rotate clockwise, and the meshing connection between the gear and the rack causes the moving box and the first sliding sleeve 54 to move along the axial direction of the rotating shaft 53. When the moving box 55 moves to one axial end of the rotating shaft 53, the dial The rod 577 hits one of the limit members 580, thereby driving the second sleeve 578, the first bevel gear 571 and the second bevel gear 572 to move along the axial direction of the first sleeve 54, so that the second bevel gear 572 is meshed and connected with the third bevel gear 573. In this way, the connecting shaft 576 and the gear 574 rotate counterclockwise, so that the movable box 55 and the first sleeve 54 move in the other axial direction of the rotating shaft 53, realizing automatic reversing. This structure is simple and can replace the bidirectional motor with a unidirectional motor to reduce the cost of use.

[0043] Furthermore, the limiting member 580 includes a limiting cylinder 101 arranged on the frame, a push rod 102 slidably arranged on the limiting cylinder 101, and a buffer spring 103 arranged between the limiting cylinder 101 and the push rod 102, which plays a buffering role to avoid tooth collision between the third bevel gear 573 and the first bevel gear 571 or the second bevel gear 572 during the engagement process, thereby improving the service life.

[0044] In this embodiment, the cleaning connecting plate 58 includes a first plate body 581 vertically arranged on the movable box 55 and a second plate body 582 integrally connected to the first plate body 581. The first plate body 581 and the second plate body 582 are distributed vertically. The second plate body 582 is provided with a strip mounting groove 583.

The support rod 591 includes a first rod body 202, a second rod body 203 and a third rod body 204 that are integrally connected. The angle between the central axis of the first rod body 202 and the central axis of the second rod body 203 is 120°~135°, preferably 130°, which improves the convenience of connecting the cleaning connecting plate 58 with the support rod 591, and can achieve cleaning of the wire rope by flipping the installation direction of the support rod 591, thereby improving the convenience of use.

[0045] In addition, a slot 7 is provided on one end face of the mounting plate 594, one end of the flexible support plate 595 is embedded in the slot 7 and is connected to the mounting plate 594 by a first bolt 8, and the first cleaning plate 596 or the second cleaning plate 597 is locked to one side face of the flexible support plate 595 by a second bolt 9, and the distance between the first cleaning plate 596 or the second cleaning plate 597 and the mounting plate 594 is 15mm to 28mm, preferably 18mm, which improves the convenience of replacing the first cleaning plate 596 and the second cleaning plate 597 and ensures the installation strength, while making the cleaning component 59 have a certain flexibility, avoiding jamming during the rotation switching of the first cleaning plate 596 and the second cleaning plate 597, thereby improving the safety of use.

[0046] Furthermore, the first cleaning plate 596 and the second cleaning plate 597 both include an integrally connected connecting portion 301 and a cleaning portion 302, the free end of the cleaning portion 302 being an arc-shaped structure 303, and a sewage outlet 304 is provided on one lateral side of the first cleaning plate 596 and the second cleaning plate 597 and located between the connecting portion 301 and the cleaning portion 302 to facilitate the discharge of sludge and improve cleanliness.
