Description

Technical Field

[0001] This utility model relates to the field of elevator parts technology, specifically an oil cup for lubricating elevator guide rails. Background Technology

[0002] The oil cup is usually installed at the bottom of the elevator car. It contains lubricating oil. When the car moves up and down, the oil in the cup can be spread onto the guide rails through a cotton rope, thereby reducing the friction between the guide shoes and the guide rails and improving the service life of the guide shoes. In the current oil cup, one end of the cotton rope is immersed in lubricating oil, and the other end is in continuous contact with the guide rail surface. However, when the car is not moving up and down, the cotton rope will still continuously transfer lubricating oil from the oil cup to the guide rails through capillary action, causing the lubricating oil in the cup to be continuously consumed. When the car moves to other positions on the guide rails, it is easy to encounter a situation where the guide rails cannot be effectively lubricated due to insufficient oil, which requires increasing the frequency of adding oil to the oil reservoir and will also affect the normal operation of the elevator. Utility Model Content

[0003] The purpose of this invention is to provide an oil cup for lubricating elevator guide rails, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The oil cup for lubricating elevator guide rails includes an oil storage cavity, a connecting member provided on the side wall of the oil storage cavity, an opening at the upper end of the oil storage cavity, a cap fastened to the opening at the upper end of the oil storage cavity, two extension cavities provided on the oil storage cavity, a lubrication assembly provided on the extension cavity, the lubrication assembly including a slider, a through groove for the slider to pass through on the side wall of the extension cavity, a guide plate for the slider to move inside the extension cavity, an iron block provided on one side of the slider, an electromagnet provided on the outside of the extension cavity, and an elastic element, one end of the elastic element being fixedly connected to the end of the slider near the electromagnet, the other end of the elastic element being fixedly connected to the inner side wall of the extension cavity away from the electromagnet, the elastic element being always in a stretched state, a sleeve provided inside the slider, a cotton rope bundle provided inside the sleeve, one end of the cotton rope bundle being located inside the extension cavity and extending to the outside of the sleeve, and the other end of the cotton rope bundle being located inside the oil storage cavity and extending to the bottom of the oil storage cavity.

[0005] Preferably, elastic scrapers are provided on the upper and lower sides of the through groove, the scrapers are rotatably connected to the extension cavity, and the two scrapers are connected by an elastic rope, which is always in a stretched state.

[0006] Preferably, the scraper is made of silicone.

[0007] Preferably, the lower end of the oil storage cavity is threadedly connected to a bottom cavity, the bottom cavity is in communication with the oil storage cavity, and one end of the cotton rope cluster located in the oil storage cavity can extend to the inner bottom of the bottom cavity.

[0008] Preferably, an observation hole is provided on the outer surface of the bottom cavity, and an observation window is provided inside the observation hole.

[0009] The beneficial effects of this utility model are:

[0010] This type of oil cup allows the cotton rope bundle to contact the guide rail surface when the elevator car is moving. Through the capillary action of the cotton rope bundle, lubricating oil is guided to the guide rail surface for lubrication. When the elevator car is not moving, the cotton rope bundle separates from the guide rail surface and retracts into the extension cavity. This prevents the lubricating oil from being guided to the guide rail surface through the cotton rope bundle and allows the lubricating oil to flow back into the extension cavity and oil storage cavity. This reduces the consumption of lubricating oil and the frequency of adding oil to the oil storage cavity, ensuring continuous and normal operation of the elevator. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-4As shown, an oil cup for lubricating elevator guide rails includes an oil storage chamber 1, a connector 2 on the side wall of the oil storage chamber 1, an upper opening of the oil storage chamber 1, and a cap 3 fastened to the upper opening of the oil storage chamber 1. Two extension chambers 4 are provided on the oil storage chamber 1, and a lubrication assembly is provided on each extension chamber 4. The lubrication assembly includes a slider 5. A through groove is provided on the side wall of the extension chamber 4 for the slider 5 to pass through. A guide plate 6 for the movement of the slider 5 is provided inside the extension chamber 4. An iron block 7 is provided on one side of the slider 5. A guide plate 6 is provided on the outer side of the extension chamber 4. The slide includes an electromagnet 8 and an elastic element 9. One end of the elastic element 9 is fixedly connected to the end of the slider 5 near the electromagnet 8, and the other end of the elastic element 9 is fixedly connected to the inner wall of the extension cavity 4 away from the electromagnet 8. The elastic element 9 is always in a stretched state. A sleeve 10 is provided inside the slider 5, and a cotton rope bundle 11 is provided inside the sleeve 10. One end of the cotton rope bundle 11 is located inside the extension cavity 4 and extends to the outside of the sleeve 10, and the other end of the cotton rope bundle 11 is located inside the oil storage cavity 1 and can extend to the bottom of the oil storage cavity 1.

[0018] The oil storage chamber 1 can be fixed to the bottom of the car or to the guide shoe via the connector 2 and bolts.

[0019] When the elevator car is not moving, in order to reduce the consumption of lubricating oil in the oil storage chamber 1, the electromagnet 8 is energized, which attracts the iron block 7 and drives the slider 5 to move closer to the electromagnet 8. This causes the cotton rope bundle 11 to be stored from the outside of the extension chamber 4 into the extension chamber 4. At this time, the cotton rope bundle 11 is not in direct contact with the elevator guide rail 16. At the same time, the elastic element 9 is further stretched. The lubricating oil attracted by the cotton rope bundle 11 through capillary action cannot be transferred to the guide rail 16. Instead, it drips into the extension chamber 4 under the action of gravity and flows back into the oil storage chamber 1, thereby reducing the waste of lubricating oil when the car is not in use.

[0020] When the car moves, the electromagnet 8 is energized, and the attraction between the electromagnet 8 and the iron block 7 disappears or becomes very weak. At this time, the elastic element 9 can contract and drive the slider 5 to move along the guide plate 6 towards the through groove, pushing the cotton rope bundle 11 towards the guide rail 16, so that one end of the cotton rope bundle 11 contacts the surface of the guide rail 16. At this time, the lubricating oil in the cotton rope bundle 11 can be transferred to the surface of the guide rail 16 to achieve lubrication of the surface of the guide rail 16, thereby reducing the friction between the guide shoe and the guide rail 16. When the cotton rope bundle 11 contacts the guide rail 16, the slider 5 will not be able to continue to move towards the guide rail 16 under the action of the elastic element 9, but will remain in a suitable position, so that the cotton rope bundle 11 can lubricate the guide rail 16, and the slider 5 will not slide out of the through groove. At the same time, when the electromagnet 8 is energized, the electromagnet 8 can still attract the iron block 7 by magnetic force.

[0021] Furthermore, during the movement of the slider 5, the sleeve 10 will come into contact with the through groove on the extension cavity 4, thereby restricting the slider 5 from moving further in the direction of the guide rail 16, thus limiting the slider 5 from continuing to move. When the sleeve 10 comes into contact with the through groove on the extension cavity 4, the electromagnet 8 can attract the iron block 7 by magnetic force.

[0022] The opening and closing of electromagnet 8 is related to the vertical movement of the car. The opening and closing of electromagnet 8 is controlled by the elevator control system. When the car moves to a floor, electromagnet 8 closes to facilitate lubrication of guide rail 16. When the car only opens and closes the door but does not move to a floor, electromagnet 8 opens to prevent the cotton rope bundle 11 from contacting guide rail 16, thus reducing the consumption of lubricating oil.

[0023] The elastic element 9 can be a rubber rope or a spring.

[0024] Furthermore, elastic scrapers 12 are respectively provided on the upper and lower sides of the through groove. The scrapers 12 are rotatably connected to the extension cavity 4. The two scrapers 12 are connected by an elastic rope 13. The elastic rope 13 is always in a stretched state. When the elastic element 9 drives the slider 5 and the cotton rope cluster 11 to move towards the guide rail 16, it will simultaneously push the scrapers 12 on the upper and lower sides of the through groove to flip, and make one end of the scraper 12 flip to the surface of the guide rail 16. When the cotton rope cluster 11 moves up or down, the scraper 12 can spread the lubricating oil on the guide rail 16 relatively evenly, thereby improving the lubrication quality and guiding the excess lubricating oil into the extension cavity 4. After the slider 5 and the cotton rope cluster 11 return to the extension cavity 4, the two scrapers 12 return to their original positions under the action of the elastic rope 13.

[0025] Furthermore, the scraper 12 is made of silicone.

[0026] Furthermore, the lower end of the oil storage chamber 1 is threadedly connected to a bottom cavity 14, which is in communication with the oil storage chamber 1. One end of the cotton rope bundle 11 located in the oil storage chamber 1 can extend to the bottom of the bottom cavity 14. When a lot of sludge accumulates in the oil storage chamber 1, the bottom cavity 14 can be removed from the oil storage chamber 1 to treat the sludge in the bottom cavity 14 separately. After cleaning the bottom cavity 14, the bottom cavity 14 can be reinstalled on the oil storage chamber 1.

[0027] Furthermore, an observation hole is provided on the outer surface of the bottom cavity 14, and an observation window 15 is provided inside the observation hole to facilitate observation of the oil level in the bottom cavity 14.

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.
