In box elevator systems, the hoist rope is a key component that connects the elevator car to the counterweight and transmits power. Its surface cleanliness directly affects the elevator's operating efficiency and safety. Traditional methods of cleaning the hoist rope usually involve fixing a dedicated cleaning device in the machine room at the top of the elevator, close to the position where the hoist rope passes. This cleaning device is designed with cleaning elements such as brushes or scrapers. During the normal up and down movement of the elevator, the hoist rope is frictionally cleaned as it passes through the cleaning element, thereby removing dust, grease, and other attachments on the surface.

[0003] In the prior art, cleaning operations often need to be performed during elevator maintenance. If the elevator needs to be started to drive the traction rope through the cleaning device, not only does this increase the operator's work risk, but it can also lead to safety accidents due to misoperation or equipment failure, posing a threat to the safety of personnel and equipment. At the same time, due to the limited space around the elevator traction motor, the installation and maintenance of the cleaning device becomes particularly difficult. In particular, for elevator traction ropes of different specifications and sizes, it is necessary to customize or replace cleaning devices of corresponding sizes. The environmental and structural designs of elevator machine rooms vary greatly, and traditional fixed cleaning devices are difficult to adapt to the installation requirements of all types of elevators.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0018] like Figure 1 、 Figure 2 and Figure 3 As shown, the device includes a base 1, a front brush fixing plate 2 and a rear brush fixing plate 3.

[0019] The base 1 provides a stable installation base for the entire cleaning device. Long waist holes 11 are opened on both sides of the base 1, which allow the device to be fine-tuned and fixed in the horizontal direction, so as to adjust the cleaning position according to actual needs and use brushes in different parts for cleaning.

[0020] The front and rear brush mounting plates 2 and 3 are located at the front and rear ends of the base 1, respectively. Both are connected to the adjustment bolt 5 via a pair of connecting ears 4, forming an adjustable clamping structure to accommodate pull ropes of varying diameters. This design ensures that the brush 6 adheres tightly and evenly to the pull rope surface, enhancing cleaning effectiveness.

[0021] A brush 6 is installed between the front and rear brush fixing plates 2 and 3 to directly remove dirt from the tow rope. To enhance brush stability and facilitate replacement, brush fixing plates 8 are located inside the front and rear brush fixing plates 2 and 3. These plates are secured to the front and rear brush fixing plates 2 and 3 via brush fixing bases 9. The brush fixing bases 9 allow for flexible installation, allowing for flexible adaptation to brush fixing plates 8 of varying lengths by selecting from multiple brush fixing holes 10 located on the front and rear of the front and rear brush fixing plates 3.

[0022] The device features two drive units 7, mounted on the left and right ends of the base 1 to enhance stability and driving force. Each drive unit 7 comprises a motor base 71, a motor 72, and a drive wheel 73. The motor 72 is mounted on the motor base 71, with its front end connected to the drive wheel 73. The drive wheel 73 has a V-shaped groove 731 around its circumference, which securely engages and drives the traction rope. The V-shaped groove 731 ensures good contact between the drive wheel 73 and the traction rope, allowing the cleaning device to move smoothly up and down the traction rope.

[0023] Specific steps:

[0024] In this embodiment, the spacing between the front and rear brush mounting plates 2 and 3 is first adjusted using bolts 5, based on the specific diameter of the drag rope, ensuring that the brush 6 fits snugly against the drag rope. Then, using the elongated waist holes 11 on the base 1, the appropriate position is selected to ensure that the drive wheel 73 can smoothly engage the drag rope and drive the device. After starting the motor 72, the drive wheel 73 begins to rotate, and its wheel groove 731 tightly mates with the drag rope, driving the entire cleaning device up and down along the drag rope.

[0025] During this process, the brush 6 continuously and evenly cleans the surface of the pull rope. To replace the brush or use a brush in a different position, the device's position can be adjusted using the elongated waist hole 11. Alternatively, the brush fixing plate 8 can be replaced with a different length as needed and secured using the brush fixing base 9 and brush fixing hole 10, achieving flexible and efficient cleaning. The entire process does not require starting the elevator, ensuring safe and convenient operation.

[0026] The above describes in detail the self-cleaning device for the traction rope of a cabin elevator provided by the present invention.
