Abstract
Description
Technical Field
[0001] This utility model relates to the field of ladder chain roller technology, and in particular to an external low-noise, low-vibration ladder chain roller lubrication assembly. Background Technology
[0002] Step chain rollers are key components of the step chain system in escalators or moving walkways. The step chain connects the individual steps, enabling them to move in a circular motion. Rollers are mounted on the step chain and roll on the track, supporting the steps and guiding them to run smoothly along a specific path. During operation, they require lubricating oil for lubrication, which not only reduces the friction between the rollers and the track, thus reducing noise and vibration, but also protects the rollers and track, reduces wear, and extends the service life of the equipment.
[0003] When existing lubrication devices are continuously dripping oil, if the rollers with large spacing are lubricated, a large amount of lubricating oil will be lost, resulting in unnecessary waste and environmental pollution. If the chain rollers are not lubricated, noise and vibration will be generated when the steps are running, which will seriously affect the riding quality of the escalator. Moreover, the frictional resistance between the rollers and the guide rail surface will be greatly increased, reducing the operating efficiency of the escalator and increasing the energy consumption of the escalator.
[0004] An existing patent (publication number: CN219472700U) discloses an automatic oiling and lubrication device for a transmission chain. The roller assembly can be lifted by the chain roller and directly contact the oil storage chamber, which reduces the volume of the oil storage chamber and squeezes out the lubricating oil. Since the roller assembly is moved under the drive of the chain, the valve body can be synchronized with the movement of the chain without the need for additional power equipment, so as to lubricate the chain at fixed time, quantity and point.
[0005] To address the aforementioned problems, existing patents offer solutions, but these solutions are not convenient for applying lubricating oil. In practical applications, due to the lack of an effective application structure, it is difficult to ensure that the lubricating oil can fully and evenly cover the roller and track surfaces, which can easily lead to insufficient or excessive lubrication. Insufficient lubrication increases the friction between the roller and track, accelerates component wear, and reduces the service life of the equipment. Excessive lubrication, on the other hand, causes excess lubricant to drip, resulting in waste of lubricating oil and pollution of the surrounding environment, which in turn affects the normal operation of the escalator and reduces the practicality of the device.
[0006] To address this, an external, low-noise, low-vibration ladder chain roller lubrication assembly is proposed. Utility Model Content

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-5 The present invention provides the following technical solution:
[0028] An external low-noise, low-vibration stepped chain roller lubrication assembly includes a chain 1, a liquid storage tank 2 at the top of the chain 1, and an oil dripping assembly 3 fixedly connected to the bottom of the liquid storage tank 2. Both sides of the bottom of the liquid storage tank 2 are fixedly connected to an applicator 4, and the applicator 4 is in contact with the surface of the chain 1. The oil dripping assembly 3 includes a U-shaped storage block 301, and a dropper 302 is fixedly connected to the front and rear sides of the U-shaped storage block 301. The U-shaped storage block 301 is connected to the liquid storage tank 2.
[0029] The application assembly 4 includes a connecting bracket 401, a storage roller 402 is rotatably connected inside the connecting bracket 401, and the surface of the storage roller 402 is provided with a number of leakage holes 403. The front and rear sides of the storage roller 402 are fixedly connected to a fixing tube 404, and a rotating ring 405 is fixedly connected to the surface of the fixing tube 404. The two fixing tubes 404 are provided with a connecting tube 406 on the side away from the storage roller 402, and the other end of the connecting tube 406 is fixedly connected to the liquid storage tank 2.
[0030] In this embodiment: Through the connecting pipe 406, the lubricating oil inside the storage tank 2 can flow smoothly into the storage roller 402 through the fixed pipe 404. Simultaneously, under the action of the drain hole 403, the lubricating oil inside the storage roller 402 can smoothly penetrate into the sponge pad 11, thereby applying lubricating oil to the surface of the chain 1. This improves the ease of use of the application component 4. Furthermore, under the action of the fixed pipe 404 and the rotating ring 405, the storage roller 402 can rotate smoothly inside the connecting bracket 401, allowing the sponge pad 11 to rotate smoothly on the surface of the chain 1. This ensures that the lubricating oil on the surface of the chain 1 is evenly applied, guaranteeing proper lubrication. The lubricating oil can fully and evenly cover the surface of the chain 1, reducing the noise and vibration generated during the operation of the ladder, ensuring the smoothness and stability of the ladder operation, and improving the practicality of the device. Then, under the action of the rotating wheel 306, the chain 1 can drive the rotating wheel 306 and the fixed bracket 305 to move, and simultaneously drive the moving rod 303 to move smoothly towards the U-shaped storage block 301, thereby driving the connecting plate 304 and the blocking block 307 to move smoothly, so that the drip tube 302 can connect with the U-shaped storage block 301 to realize the dripping of lubricating oil, thereby lubricating the chain 1, reducing the waste of lubricating oil, and improving the ease of use of the oil dripping component 3.
[0031] Specifically, such as Figure 4 As shown, a movable rod 303 is movably connected to the bottom of the U-shaped storage block 301, and the top of the movable rod 303 extends into the interior of the U-shaped storage block 301 and is fixedly connected to a connecting plate 304. A fixed bracket 305 is fixedly connected to the bottom of the movable rod 303, and a rotating wheel 306 is rotatably connected inside the fixed bracket 305. A blocking block 307 is fixedly connected to the front and rear sides of the bottom of the connecting plate 304, and the surface of the blocking block 307 is in contact with the inner wall of the dropper 302.
[0032] Specifically, such as Figure 4 As shown, telescopic rods 5 are fixedly connected to both sides of the top of the fixed bracket 305. Springs 6 are sleeved on the surface of the telescopic rods 5, and the side of the telescopic rods 5 away from the fixed bracket 305 is fixedly connected to the U-shaped storage block 301.
[0033] Specifically, such as Figure 4 As shown, the bottom of the U-shaped storage block 301 is provided with a moving hole 7 for use with the moving rod 303, and a rubber sealing ring 8 is provided inside the moving hole 7.
[0034] In this embodiment: the moving rod 303 and the moving hole 7 work together to allow the moving rod 303 to move smoothly under the restriction of the moving hole 7, simultaneously driving the connecting plate 304 and the blocking block 307 to move, so that the dropper 302 can connect with the U-shaped storage block 301, realizing the smooth dripping of lubricating oil. At the same time, under the action of the rubber sealing ring 8, the leakage of lubricating oil in the U-shaped storage block 301 can be avoided, ensuring that the oil dripping assembly 3 is always in normal operation, improving the stability of the oil dripping assembly 3. Then, under the action of the telescopic rod 5, the movement position of the fixed bracket 305 can be restricted, and the movement of the connecting plate 304 and the blocking block 307 can be restricted simultaneously. At the same time, under the action of the spring 6, the connecting plate 304 and the blocking block 307 can be smoothly reset, so that the dropper 302 can be smoothly blocked or opened, thereby freely controlling the dripping of lubricating oil, reducing the waste of lubricating oil, and improving the ease of use of the oil dripping assembly 3.
[0035] Specifically, such as Figure 5 As shown, the front and rear sides of the connecting bracket 401 are provided with rotating holes 9 for use with the fixing tube 404, and the surface of the fixing tube 404 is in contact with the inner wall of the rotating hole 9. The inner wall of the rotating hole 9 is provided with a rotating groove 10 for use with the rotating ring 405, and the surface of the rotating ring 405 is in contact with the inner wall of the rotating groove 10.
[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a sponge pad 11 is fitted onto the surface of the storage roller 402, and the sponge pad 11 is in contact with the surface of the chain 1.
[0037] In this embodiment: the fixed tube 404 and the rotating hole 9 work together to allow the fixed tube 404 to move smoothly inside the rotating hole 9. At the same time, under the restriction of the rotating groove 10, the rotating ring 405 rotates smoothly under the restriction of the rotating groove 10. This restricts the rotation of the fixed tube 404 and the storage roller 402, thereby driving the sponge pad 11 to rotate on the surface of the chain 1. Under the action of the sponge pad 11, the lubricating oil can be absorbed and evenly applied, ensuring that the lubricating oil can fully and evenly cover the surface of the chain 1. This reduces the noise and vibration generated during the operation of the ladder, ensures the smoothness and stability of the ladder operation, and improves the ease of use of the application component 4.
[0038] Specifically, such as Figure 3 As shown, a data processor 12 is fixedly connected to the bottom of the front side of the liquid storage tank 2, and a detection rod 13 is fixedly connected to the rear side of the data processor 12. The side of the detection rod 13 away from the data processor 12 extends into the interior of the liquid storage tank 2.
[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a signal transmitter 14 is fixedly connected to the right side of the bottom front side of the liquid storage tank 2, and the signal transmitter 14 is electrically connected to the data processor 12.
[0040] In this embodiment: by using the data processor 12 in conjunction with the detection rod 13, the condition of the lubricating oil inside the liquid storage tank 2 can be detected in real time, and the data can be fed back to the data processor 12 for processing. At the same time, under the action of the signal transmitter 14, the data processed by the data processor 12 can be sent to the external control console, which can promptly remind the staff to perform subsequent operations, ensuring the normal use of the device and improving the ease of use of the device.
[0041] Working Principle: During the operation of the escalator, the lubricating oil inside the storage tank 2 flows smoothly into the storage roller 402 through the fixed pipe 404 via the connecting pipe 406. Simultaneously, the lubricating oil in the storage roller 402 smoothly penetrates the sponge pad 11 through the drain hole 403. When the escalator starts, the chain 1 moves smoothly, causing the sponge pad 11 and storage roller 402 to rotate smoothly within the connecting bracket 401 under the constraint of the rotating ring 405. This ensures that the lubricating oil is evenly applied to the surface of the chain 1, reducing noise and vibration during operation and guaranteeing the smoothness and stability of the escalator. Simultaneously, the movement of the chain 1 causes the rotating wheel 306 and the fixed bracket 305 to move, synchronously moving the moving rod 303 smoothly towards the U-shaped storage block 301, which in turn causes the connecting plate 304 and the blocking block 307 to move smoothly. The dropper 302 can connect with the U-shaped storage block 301, allowing the lubricating oil in the U-shaped storage block 301 to drip smoothly and lubricate the chain 1. Under the action of the telescopic rod 5, the movement of the fixed bracket 305 can be restricted, and the movement of the connecting plate 304 and the blocking block 307 can be restricted simultaneously. When the chain 1 stops running, the spring 6 generates a reaction force, which drives the connecting plate 304 and the blocking block 307 to reset smoothly, so that the dropper 302 can be blocked or opened smoothly. This allows for free control of the dripping of lubricating oil, reducing the waste of lubricating oil. Finally, under the action of the detection rod 13, the lubricating oil level inside the liquid storage tank 2 can be detected in real time, and the data can be fed back to the data processor 12 for processing. At the same time, under the action of the signal transmitter 14, the data processed by the data processor 12 can be sent to the external control console, which can promptly remind the staff to perform subsequent operations and ensure the normal use of the device.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
