Description

Technical Field

[0001] This invention relates to the field of elevator parts technology, and in particular to an elevator oil cup. Background Art

[0002] Elevator oil cups, typically installed on elevator guide shoes, are essential lubrication devices. They not only improve the reliability of elevator guide rail guidance but also extend the service life of the guide rails. Elevator oil cups reduce friction between the guide shoe liner and the guide rail by lubricating the guide shoe, thereby improving the elevator's operational stability. An elevator oil cup mainly consists of an oil-filled cup body and felt. The felt absorbs the lubricating oil inside the cup body to lubricate the guide rails. However, in existing technology, elevator oil cups shake during elevator movement, causing oil to overflow from the cup body and squeezing the felt, displacing the lubricating oil absorbed by the felt. Simultaneously, due to the volatility of the oil, leakage can occur when the oil cup is stationary due to the absorbency of the felt, resulting in oil waste and contamination. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an elevator oil cup that solves the problems existing in the prior art where the elevator oil cup shakes during elevator movement, causing oil inside the cup to overflow and the pressure on the felt to squeeze out the lubricating oil adsorbed on the felt.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] Example 1:

[0027] In the prior art, the elevator oil cup will shake during the elevator movement, causing the oil inside the cup to overflow and the pressure on the felt to squeeze out the lubricating oil adsorbed on the felt; at the same time, because the oil is volatile, the oil cup will also leak when it is stationary due to the adsorption of the felt, resulting in oil waste and pollution.

[0028] To solve the above-mentioned technical problems, Embodiment 1 of the present invention provides an elevator oil cup, such as... Figures 1-5 As shown, the device includes a cup body 1, a lubrication mechanism 2, a felt assembly 3, and an oil recovery mechanism 4. The cup body 1 is a cylindrical structure with a first opening 11 at the top. The cup body 1 has maximum and minimum scale lines for lubricating oil, which facilitates visualization. A cup lid 5 is detachably installed on the cup body 1, which can tightly cover the first opening 11. The lubrication mechanism 2 is fixedly installed on the cup body 1 and is located at the edge of the first opening 11. The lubrication mechanism 2 is a cylindrical structure with a second opening 21 at the top and is connected to the cup body 1. The cup lid 5 can tightly cover the second opening 21. The inner bottom of the lubrication mechanism 2 is set at an acute angle to the cup body 1. The lubrication mechanism 2 has a lubrication groove 22 for passing through an elevator guide rail. One end of the felt assembly 3 is located inside the cup body 1, and the other end of the felt assembly 3 is located inside the lubrication mechanism 2. The oil recovery mechanism 4 is fixedly installed inside the lubrication mechanism 2 and is connected to the lubrication mechanism 2.

[0029] The elevator oil cup provided by this invention is installed on the guide shoe during use. The elevator guide rail passes through the lubrication groove 22. The cup body 1 contains lubricating oil, which is guided to the lubrication groove 22 through the felt assembly 3. During elevator operation, the elevator guide rail squeezes the felt assembly 3, thereby lubricating the elevator guide rail. The elevator oil cup provided by this invention, on the one hand, by setting up an oiling mechanism 2, a felt assembly 3, and an oil recovery mechanism 4, allows the elevator guide rail to be lubricated by squeezing the felt assembly 3 with the squeezed lubricating oil. The oil recovery mechanism 4 ensures that any lubricating oil overflowing due to squeezing can be promptly recovered back into the oiling mechanism 2, thus completing the recycling and reuse of the lubricating oil and avoiding pollution of the elevator car and waste of resources caused by lubricating oil overflow. On the other hand, when the lubricating oil is recovered to the oiling mechanism 2, the oil cup can be used to further clean and recycle the lubricating oil.

[0030] When the lubricating oil is inside the oil filling mechanism 2, only a portion of the lubricating oil can flow back to the cup body 1 along the filling mechanism 2, while a considerable amount of lubricating oil remains inside the filling mechanism 2. This indicates that the lubricating oil cannot be completely recovered, and it is also affected by oil stains and dust during the elevator's stationary state, impacting the lubrication of the elevator guide rails. Therefore, by setting the inner bottom of the filling mechanism 2 at an acute angle to the cup body 1, as detailed in [reference needed], [further details can be found here]. Figure 2The angle α is less than 90°, ensuring that the lubricating oil in the lubrication mechanism 2, as well as the lubricating oil leaking due to the compression of the felt assembly 3, can only flow back into the cup body 1 through the lubrication mechanism 2. This improves the working reliability of the elevator oil cup, further increases the lubricating oil recycling rate, and avoids lubricating oil contamination and elevator car contamination, thus improving elevator ride comfort. Therefore, the elevator oil cup provided by this invention has a simple structure, is easy to implement, and is convenient to install and replace. It avoids lubricating oil waste and contamination, allows lubricating oil to be recycled, improves the utilization rate of lubricating oil, solves the problem of lubricating oil contamination that has plagued the elevator industry, further improves the elevator riding environment, and reduces the cleaning workload of cleaning personnel.

[0031] To further improve the reliability of elevator oil cup lubrication and the recycling rate of lubricating oil, the elevator oil cup provided in this embodiment further includes an oil recovery mechanism 4 comprising a first pressure plate 41. The first pressure plate 41 is fixedly disposed within the oil filling mechanism 2, and a gap is left between the first pressure plate 41 and the lubrication groove 22, forming an oil return groove 411 for oil return flow. A plurality of diversion grooves 412 are provided on the first pressure plate 41, and the diversion grooves 412 are symmetrically arranged about the center of the lubrication groove 22. The height of the first pressure plate 41 is greater than the height of the lubrication groove 22, that is, there is a height difference between the first pressure plate 41 and the lubrication groove 22. By setting the first pressure plate 41, on the one hand, the first pressure plate 41 can work with the cup cover 5 to form a better squeezing effect on the felt assembly 3, thereby improving the reliability of the lubrication of the elevator guide rail by the oil cup; on the other hand, the setting of the return oil groove 411 and the diversion groove 412 allows the lubricating oil recovered to the oiling mechanism 2 to flow back to the cup body 1 from the return oil groove 411 and the diversion groove 412 respectively, thereby further improving the reliability of the elevator oil cup for the recovery of lubricating oil.

[0032] To further improve the reliability of the elevator oil cup lubrication operation and the recovery rate of the lubricating oil, the elevator oil cup provided in this embodiment further includes a plurality of second pressure plates 51 fixedly installed on the cup cover 5; all the second pressure plates 51 are symmetrically arranged on the cup cover 5, and the second pressure plates 51 press against the felt assembly 3. By setting the second pressure plates 51, in conjunction with the aforementioned first pressure plate 41, the two can work together to squeeze the felt assembly 3, thereby further improving the reliability of the oil cup's lubrication of the elevator guide rail, while the squeezed-out lubricating oil can be promptly recovered into the refueling mechanism 2, thereby further improving the reliability of the elevator oil cup's lubricating oil recovery operation.

[0033] To further improve the utilization rate of lubricating oil, the elevator oil cup provided in this embodiment further includes a felt assembly 3 comprising a felt plate 31, two felt strips 32, and a felt block 33; the felt plate 31 is detachably fixed inside the cup body 1 and is fitted against the inner wall surface of the cup body 1; one end of the felt strip 32 is disposed inside the cup body 1, and the other end of the felt strip 32 is disposed inside the oiling mechanism 2, with the felt strip 32 passing through the felt plate 31 and the felt block 33; the felt block 33 is detachably fixed inside the oiling mechanism 2 and can cover the second opening 21. By setting up a felt plate 31, two felt strips 32 and a felt block 33, the felt strips 32 have strong adsorption properties, which adsorb the lubricating oil in the cup 1 onto the felt plate 31 and the felt block 33. Specifically, the felt plate 31 and the felt block 33 are sheet-type felt, which can reduce the amount of lubricating oil stored. This makes the amount of lubricating oil squeezed out by the elevator guide rail to the felt assembly 3 relatively small when the elevator oil cup is in use, thereby further improving the utilization rate of the elevator oil cup for lubricating oil.

[0034] To further improve the reliability of elevator oil cup lubrication, the elevator oil cup provided in this embodiment further includes an oil collection mechanism 2 comprising an oil collection tank body 23. The oil collection tank body 23 has a cylindrical structure with a second opening 21 at the top. The oil collection tank body 23 is fixedly mounted on the cup body 1 and is connected to the cup body 1. A lubrication groove 22 is formed on the oil collection tank body 23. The other end of the felt assembly 3 is disposed inside the oil collection tank body 23. The inner bottom of the oil collection tank body 23 is set at an acute angle to the cup body 1. Furthermore, the oil collection mechanism 2 also includes two limiting parts 24. The limiting parts 24 have a plate-like structure and are fixedly mounted on the cup body 1.

[0035] The oil collection tank body 23 is fixedly installed inside the oil collection tank body 23. Two limiting parts 24 are symmetrically arranged inside the oil collection tank body 23 about the lubrication groove 22. One end of the limiting part 24 is fixedly connected to the inner wall of the oil collection tank body 23, and the other end of the limiting part 24 is a free end. The other end of the limiting part 24 is spaced apart from the felt assembly 3. The oil collection tank body 23 and the cup body 1 are integrally structured. By setting up the oil collection tank body 23 and the limiting part 24, specifically, the limiting part 24 is a plate-shaped structure fixed and vertically set in the oil collection tank body 23. Since there is a gap between the felt plate 31 and the oil collection tank body 23, specifically at both ends of the felt plate 31, when the elevator is running and the oil cup is shaking, the lubricating oil may flow into the oil collection tank body 23 from the gap at both ends. Therefore, the setting of the limiting part 24 enables the lubricating oil to be limited by the limiting part 24 in this case, preventing a large amount of lubricating oil from flowing back into the oil collection tank body 23, and further improving the reliability of the elevator oil cup lubrication operation.

[0036] To facilitate the assembly and disassembly of the elevator oil cup, the elevator oil cup provided in this embodiment further includes multiple snap fasteners 52 fixedly installed on the cup lid 5; and multiple protrusions 25 fixedly installed on the refueling mechanism 2; the snap fasteners 52 can engage with the protrusions 25. By providing the snap fasteners 52 and protrusions 25, the cup lid 5, cup body 1, and refueling mechanism 2 can be quickly opened and closed via the snap fasteners 52 and protrusions 25. Its structure is simple, easy to install, and low in cost, thereby improving the efficiency of the operator in assembling and disassembling the elevator oil cup, and also improving the economy of the elevator oil cup. Specifically, in this embodiment, the cup lid 5 and cup body 1 are connected by a hinge, and the snap fasteners 52 and protrusions 25 are made of a material with excellent ductility, allowing for repeated folding and use without damage, further extending the service life of the snap fasteners 52 and protrusions 25.

[0037] To further facilitate the positioning and disassembly of the elevator oil cup, the elevator oil cup provided in this embodiment further includes an adjusting bolt assembly 6; the bottom of the cup body 1 is provided with a mounting groove 12, and the adjusting bolt assembly 6 is disposed in the mounting groove 12. The adjusting bolt assembly 6 can be reciprocated along the extension direction of the mounting groove 12. By setting the adjusting bolt assembly 6 and the mounting groove 12, the adjusting bolt assembly 6 can be confined within the mounting groove 12, and the operator can adaptively adjust the installation position of the elevator oil cup on the guide shoe. Specifically, the mounting groove 12 is a rectangular groove with a large adjustment range, thereby further improving the positioning and disassembly convenience of the elevator oil cup.

[0038] To further improve the reliability of elevator oil cup lubrication, the elevator oil cup provided in this embodiment further includes a retaining strip 13 fixedly installed at the outer edge of the cup body 1 and the lubrication mechanism 2; a retaining groove 53 is provided on the cup cover 5; a sealing element is detachably fixed in the retaining groove 53; and the retaining strip 13 is engaged with the retaining groove 53. By setting the retaining strip 13, the retaining groove 53, and the sealing element, a sealed connection can be achieved at the joint between the cup body 1, the lubrication mechanism 2, and the cup cover 5, thereby preventing the leakage of lubricating oil from the joint, improving the reliability of elevator oil cup lubrication, and further improving the ride comfort of the elevator.

[0039] In summary, the elevator oil cup provided by this invention, on the one hand, by setting up an oiling mechanism, a felt assembly, and an oil recovery mechanism, allows the elevator guide rail to be lubricated by the squeezed oil from the felt assembly. The oil recovery mechanism ensures that the oil overflowing due to the squeeze is promptly recovered into the oiling mechanism, thus completing the recycling and reuse of the lubricating oil and avoiding the pollution of the elevator car and the waste of resources caused by the overflow of lubricating oil. On the other hand, by setting the inner bottom of the oiling mechanism at an acute angle to the cup body, the lubricating oil in the oiling mechanism and the lubricating oil leaking due to the squeeze of the felt assembly can only flow back into the cup body through the oiling mechanism. This improves the working reliability of the elevator oil cup, further increases the lubricating oil recycling rate, and also avoids the pollution of the lubricating oil and the elevator car, thus improving the ride comfort of the elevator.
