Detailed Implementation

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. Example

[0028] Please see Figures 1-11This utility model provides the following technical solution: a vibration-damping and low-noise elevator, comprising an elevator structure, the elevator structure including a chassis 4, a cable 7, and a frame structure, the chassis 4 being installed inside the frame structure, a buffer and vibration-damping structure 5 being provided below the frame structure, and auxiliary moving structures 2 being provided on both sides of the frame structure, and cleaning structures 6 being provided on both sides of the frame structure, the cleaning structure 6 including a second mounting body 601, a connecting rod 602, a fixing plate 603, a semi-circular ring 604, a telescopic spring 605, a movable column 606, a side connecting plate 607, a square mounting plate 608, and a second roller 609; the second mounting body 601 and the fixing plate 603 are mounted on the frame surface, the second mounting body 601 has a through cavity inside, and the surface of the second mounting body 601 has an inclined opening. A square mounting plate 608 is provided inside the through cavity. A limiting post is installed on the surface of the square mounting plate 608 and passes through the opening. A second roller 609 is movably installed on the inner side of the square mounting plate 608. The surface of the second roller 609 has protrusions distributed in a ring array. A connecting rod 602 is movably connected to the lower end of the square mounting plate 608. Two sets of elastic structures are provided at the lower end of the connecting rod 602. The connecting rod 602 passes through the fixed plate 603 and is clamped by the two sets of elastic structures. A movable column 606 is movably installed on the rear end of the fixed plate 603. Side connecting plates 607 are connected to both ends of the movable column 606. The two sets of side connecting plates 607 face opposite directions. A space is left between the two sets of second rollers 609. The two sets of side connecting plates 607 are connected by a connecting column 8.

[0029] In this implementation plan, the specific working principle is as follows: When the elevator is running, the guide rail is exposed to the elevator shaft for a long time, and dust and oil accumulate on its surface, causing foreign matter to condense. When the first roller 209 runs, it will cause vibration and noise problems. To solve this problem, when the elevator is running, the surface of the mounting body 601 can scrape off the foreign matter on one side of the guide rail, so that the first roller 203 will not vibrate when it comes into contact with the guide rail. Secondly, in order to ensure the cleanliness of other sides of the guide rail, the protrusions on the surface of the second roller 609 can break up the foreign matter, allowing it to fall off and thus preventing the sliding groove 2 from being blocked. 02. Regarding the vibration and noise issues caused by contact with the guide rail, when the second roller 609 comes into contact with a foreign object, the foreign object may be quite hard. At this time, the second roller 609 will move in the opposite direction due to the force. However, due to the limiting effect of the inclined opening and the squeezing between the second roller 609 and the guide rail, the foreign object is cleared away. In this way, the upward movement force of the elevator itself can be used to effectively break the foreign object, preventing vibration and noise caused when the foreign object comes into contact with the first roller 209. Secondly, after the foreign object is cleared away, it is reset through the action of the connecting rod 602, the semi-circular ring 604, and the telescopic spring 605.

[0030] Based on the above, the specific framework structure can be found in [reference needed]. Figure 1 andFigure 4 As can be seen, the frame structure includes a top panel 1, a chassis frame 3, and a bottom mounting platform 9. The top panel 1 is symmetrically arranged vertically, with chassis frames 3 at both ends. A buffer and shock-absorbing structure 5 is installed at the lower end of the top panel 1, and a square mounting plate is installed at the upper end of the top panel 1. An auxiliary moving structure 2 is installed on the square mounting plate, and a cleaning structure 6 is provided on the outer surface of the square mounting plate. The chassis frame 3 mainly provides mounting space for the chassis 4 and fixes the chassis 4 as a whole. The buffer and shock-absorbing structure 5 is installed at the lower end of the top panel 1, so that when the elevator descends to the bottom floor, it plays an effective buffering role and prevents more severe vibrations.

[0031] For details regarding the buffer and shock absorption structure 5, please refer to [link / reference needed]. Figure 6 As can be seen, the buffer and shock absorption structure 5 includes a second mounting plate 501, a cavity tube 502, a telescopic column 503, a contact base plate 504, and an internal spring 505. The second mounting plate 501 is installed on the lower end face of the top 1 and has a cavity inside. The telescopic column 503 is movably installed in the cavity. The upper end of the telescopic column 503 is provided with a ring. The ring can move in the cavity and limit the telescopic column 503. The internal spring 505 is sleeved on the surface of the cavity tube 502. The contact base plate 504 is installed at the lower end of the telescopic column 503. When the elevator moves down to the bottom floor, it contacts the ground or other elevator structures through the contact base plate 504 and is buffered by the internal spring 505.

Figure 5 and Figure 7 As can be seen, the auxiliary moving structure 2 includes a first mounting plate 201, a sliding groove 202, and a first roller 203.

Two sets of first rollers 203 are movably mounted on the inner side of the first mounting plate 201, and the two sets of first rollers 203 are connected by a shaft. A sliding groove 202 is installed on the inner end face of the shaft. The sliding groove 202 facilitates the first mounting plate 201 to be firmly fixed on the guide rail. Secondly, the first rollers 203 facilitate the movement of the elevator. It should also be noted that the width of the sliding groove 202 is slightly larger than the width of the guide rail and the groove contact end.

[0033] For details on enhancing the buffering capacity of the damping structure 5, please refer to [the relevant documentation / reference]. Figure 6 As can be seen, an external spring 506 is also fitted on the outer surface of the cavity tube 502, which encloses the internal spring 505.
