Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance equipment technology, specifically an elevator wire rope decontamination device. Background Technology

[0002] Elevator wire ropes are usually coated with lubricating oil to reduce friction and wear. However, over long-term operation, this lubricating oil can attract dust, debris, metal shavings, and other contaminants, forming sludge. Excessive sludge can impair lubrication, accelerate wire rope wear, and cover the wire rope surface, making it difficult to inspect for broken wires, rust, and other problems, thus accelerating the aging and corrosion of the wire rope.

[0003] When cleaning oil sludge from existing wire ropes, wire brushes are often used. However, oil sludge tends to accumulate inside the wire brush. As the wire rope moves downwards from above the wire brush and passes through it, the oil sludge accumulated on the brush can easily re-adhere to the wire rope from below, resulting in poor treatment of oil sludge on the wire rope and low treatment efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an elevator wire rope cleaning device, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The elevator wire rope cleaning device includes two assembleable installation cavities. Each installation cavity has a baffle inside. Guide plates are rotatably connected to the interior of both installation cavities. An arc-shaped scraper is provided at the upper end of each guide plate. The guide plate and the installation cavity are connected by a tension spring, which is always in a stretched state. A rotating shaft is provided inside each installation cavity. A handle is provided at one end of the rotating shaft. A limit block is provided on the rotating shaft. The limit block has three planes: plane one, plane two, and plane three. When plane one is in contact with the baffle, plane three is in contact with the lower surface of the guide plate. Simultaneously, the two scrapers on the two guide plates are assembled into a ring. When plane two is in contact with the lower surface of the guide plate, the line connecting the shortest distance between the axis of the rotating shaft and the lower surface of the guide plate is perpendicular to the lower surface of the guide plate.

[0006] Preferably, the upper end of the scraper is provided with an arc-shaped notch.

[0007] Preferably, a bottom plate is provided at the lower end of the guide plate, and the bottom plate and the guide plate together form a collection cavity with an opening at the upper end.

[0008] Preferably, one of the mounting cavities is provided with a positioning rod on its side, and the other mounting cavity is provided with a positioning hole that mates with the positioning rod on its side.

[0009] Preferably, ear plates are provided on both sides of the mounting cavity, and waist holes are provided on the ear plates.

[0010] The beneficial effects of this utility model are:

[0011] When in use, this type of wire rope cleaning device allows the oil sludge scraped off by the scraper to move downwards along the guide plate, preventing the oil sludge from accumulating at the scraper and squeezing it. This ensures that the scraper can be stably attached to the surface of the wire rope, improving the cleaning efficiency and effect. Furthermore, the handle allows for easy control of whether the scraper contacts the wire rope. When not scraping oil sludge from the wire rope, the limiting block holds the guide plate in place, maintaining a distance between the scraper and the wire rope. This reduces wear on both the wire rope and the scraper, extending the scraper's service life. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-5As shown, an elevator wire rope cleaning device includes two assembleable mounting cavities 2. A baffle 3 is installed inside each mounting cavity 2. Guide plates 4 are rotatably connected to the interior of each mounting cavity 2. An arc-shaped scraper 5 is installed at the upper end of each guide plate 4. The guide plate 4 is connected to the mounting cavity 2 via a tension spring 6, which is always under tension. A rotating shaft 7 is installed inside each mounting cavity 2. A handle 8 is installed at one end of the rotating shaft 7. A limit block 9 is installed on the rotating shaft 7. The limit block 9 has three planes: a first plane 10, a second plane 11, and a third plane 12. When the first plane 10 is in contact with the baffle 3, the third plane 12 is in contact with the lower surface of the guide plate 4. Simultaneously, the two scrapers 5 on the two guide plates 4 are assembled into a ring. When the second plane 11 is in contact with the lower surface of the guide plate 4, the line connecting the shortest distance between the axis of the rotating shaft 7 and the lower surface of the guide plate 4 is perpendicular to the lower surface of the guide plate 4.

[0021] The device is installed on the main frame 17, which is equipped with a traction motor, a speed limiter, a traction sheave, and a wire rope 1. The two ends of the wire rope 1 are the counterweight system and the car, respectively. When cleaning the sludge on the wire rope 1, either the car or the counterweight system is first raised to the highest position, while the other is in the lowest position. When the cleaning device and the car are on the same side of the traction sheave, and the counterweight system is on the other side of the traction sheave, then the car needs to be raised to the highest position first. If the cleaning device and the counterweight system are on the same side of the traction sheave, then the counterweight system needs to be raised to the highest position first. That is, regardless of whether the car or the counterweight system is on the same side of the traction sheave as the cleaning device, either the car or the counterweight system is raised to the highest position.

[0022] In this embodiment, the cleaning device and the counterweight system are located on the same side of the traction sheave. First, the counterweight system, i.e., the counterweight frame and counterweight blocks, needs to be raised to its highest position. Once the counterweight frame and counterweight blocks are at their highest position, a portion of the sludge on the wire rope 1 is manually removed. Then, the shaft 7 is rotated by the handle 8. During rotation, under the tension of the tension spring 6, the plane 12 of the limiting block 9 can contact the lower surface of the guide plate 4, and the plane 10 can also contact the baffle 3. When the plane 10 contacts the baffle 3, the baffle 3 restricts the tension spring 6 from driving the limiting block 9 to rotate. Because some of the sludge on the wire rope 1 has been manually removed beforehand, the scrapers 5 on both guide plates 4 can adhere to the surface of the wire rope 1. The two scrapers 5 can cover the entire wire rope 1. When the scrapers 5 are attached to the surface of the wire rope 1, the counterweight system, i.e., the counterweight frame and counterweight blocks, is controlled to move at a speed lower than normal operation. As the wire rope 1 moves downwards, it continuously passes through two scrapers 5. Under the action of the tension spring 6, the scrapers 5 can scrape off the oil and sludge on the surface of the wire rope 1. The scraped oil and sludge can move downwards along the guide plate 4 under the action of gravity to prevent a large amount of oil and sludge from accumulating at the scrapers 5. When the counterweight frame and counterweight block descend to the lowest position, the handle 8 drives the rotating shaft 7 to rotate, so that the plane 11 contacts the lower surface of the guide plate 4. At this time, the limiting block 9 can lock the guide plate 4, that is, under the action of tension spring 6, the wire rope 1 moves downwards. Even under the action of spring 6, the guide plate 4 cannot be rotated in the opposite direction. When the scrapers 5 on the two guide plates 4 are separated, the control, i.e., the counterweight frame and counterweight block, rise to the highest point. At this time, the scrapers 5 on the guide plate 4 will not contact the wire rope 1. After the counterweight frame and counterweight block rise to the highest point, the handle 8 controls the rotating shaft 7 to rotate, so that the two scrapers 5 are aligned again and attached to the surface of the wire rope 1. Then, the control controls the counterweight frame and counterweight block to move downward, so as to achieve secondary scraping of oil and sludge from the wire rope 1.

[0023] The scraper 5 is made of metal. Since the wire rope 1 is woven from multiple strands of steel wire, the scraper 5 cannot completely remove the sludge from the gaps in the wire rope 1. It can only remove the surface sludge. However, after the scraper 5 cleans the sludge, the thickness of the remaining sludge on the wire rope 1 is sufficient for the normal use of the wire rope 1. This method can conveniently and quickly remove the sludge. However, for a more thorough removal of the sludge on the wire rope 1, depending on the usage scenario of the wire rope 1 and regional differences, after scraping the sludge off the surface of the wire rope 1 with the scraper 5 at regular intervals, a specific cleaning agent can be used manually to achieve a deeper cleaning of the sludge adhering to the wire rope 1.

[0024] When the elevator is in normal use, the plane 11 of the limit block 9 needs to be in contact with the lower surface of the guide plate 4, so that the scraper 5 is away from the wire rope 1, in order to avoid serious wear caused by long-term friction between the scraper 5 and the wire rope 1.

[0025] Furthermore, the upper end of the scraper 5 is provided with an arc-shaped notch to better guide the sludge into the guide plate 4 and further reduce the accumulation of sludge at the scraper 5.

[0026] Furthermore, a bottom plate 13 is provided at the lower end of the guide plate 4. The bottom plate 13 and the guide plate 4 together form a collection chamber with an opening at the upper end, allowing the sludge to enter the collection chamber and thus preventing the sludge from entering the installation chamber 2. When there is a lot of sludge in the collection chamber, the staff needs to transfer the sludge out of the collection chamber in time to prevent the sludge from overflowing into the installation chamber 2.

[0027] Furthermore, a positioning rod 14 is provided on the side of one of the mounting cavities 2, and a positioning hole that cooperates with the positioning rod 14 is provided on the side of the other mounting cavity 2, so as to facilitate the alignment of the two mounting cavities 2.

[0028] Furthermore, ear plates 15 are provided on both sides of the mounting cavity 2, and waist holes 16 are provided on the ear plates 15 to facilitate fixing the mounting cavity 2 to the main frame 17 with bolts.

[0029] When installing the device, the two mounting cavities 2 need to be located on both sides of the wire rope 1. After the two mounting cavities 2 are joined together, the mounting cavities 2 are fixed to the main frame 17. The two baffles 3 form an annular protective ring, and the wire rope 1 passes through the protective ring formed by the two baffles 3.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
