Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an elevator track vibration isolation device. Background Technology

[0002] The design of elevator track vibration isolation devices aims to reduce vibration and noise generated during elevator operation, improve passenger comfort, and protect the building structure. Currently, elevator track vibration occurs because the mass of the car and counterweight shifts due to gravity and motion during elevator operation. When the elevator car shifts, a slight deviation occurs between it and the elevator track, causing vibration between the track and the car. The magnitude of the vibration deviation increases, resulting in noticeable noise that can be inconvenient for passengers. Furthermore, vibration can cause wear or loosening of the elevator track, posing a safety risk and reducing its durability, indirectly affecting the elevator's safety and performance.

[0003] Therefore, it is necessary to develop an elevator track vibration isolation device. Utility Model Content

[0022] This utility model provides the following technical solution: an elevator track vibration isolation device, please refer to... Figures 1-4 The system includes an elevator track 1 and a car 2. Mounting brackets 3 are installed on both the front and rear ends of one side of the outer wall of the elevator track 1. A vibration isolation plate A301 is installed on one side of the mounting bracket 3. Dampers A302 are installed on the upper and lower parts of the interior of the mounting bracket 3. The output end of the damper A302 is fixedly connected to one side of the outer wall of the vibration isolation plate A301. A damping spring A303 is installed at the center of one side of the outer wall of the mounting bracket 3. One end of the damping spring A303 is connected to the vibration isolation plate A301. One side of the outer wall is fixedly connected, and rollers A304 are installed on the other side of the outer wall of the vibration isolation plate A301. The front and rear ends of the elevator track 1 are respectively installed with mounting brackets 3, and the output end of the damper A302 in the mounting bracket 3 is fixed to the vibration isolation plate A301. According to the vibration isolation plate A301 and the mounting bracket 3, the damping spring A303 is set between the vibration isolation plate A301 and the mounting bracket 3, so that the damping spring A303 is matched with the damper A302 to enhance the vibration resistance and damping effect of the vibration isolation plate A301.

[0023] Vibration isolation components are installed at the center of both outer walls of the car 2. Each vibration isolation component includes a track frame 4. Rollers B401 are installed on the inner wall of one side of the track frame 4. The interior of the track frame 4 is slidably connected to the outer wall of the elevator track 1. Vibration isolation plates B402 are installed on the upper and lower sides of one side of the interior of the track frame 4. A guide frame 403 is installed on the outer wall of one side of the vibration isolation plate B402. A guide column 404 is slidably connected inside the guide frame 403. A limit ring 405 is installed at one end of the guide column 404, and the other end of the guide column 404 is connected to the other side of the track frame 4. The inner wall of the guide column 404 is fixedly connected to the outer wall of the guide column 404. A damping spring B406 is installed on the outer wall of the other side of the track frame 4. A damper B407 is rotatably connected to the inner wall of the other side of the track frame 4. The output end of the damper B407 is rotatably connected to the outer wall of the vibration isolation plate B402. Rollers C408 are installed on the outer wall of the other side of the vibration isolation plate B402. The two sets of track frames 4 on the car 2 are slidably set outside the elevator track 1. A set of rollers A304 is set between the vibration isolation plate A301 and the track frame 4. The inner wall of the track frame 4 and the elevator track are fixedly connected to the guide column 404. An array of rollers B401 is also installed between the two rails to clamp the vibration isolation plates A301 onto the rail frame 4. The rollers A304 ensure smooth movement of the rail frame 4. Meanwhile, the rollers B401 on the inner wall of the rail frame 4 prevent friction with the elevator rail 1 and do not affect the smooth movement of the rail frame 4. Two sets of vibration isolation plates B402 are slidably connected to the guide frame 403 on the rail frame 4 via guide columns 404. A damper B40 is installed between the vibration isolation plates B402 and the rail frame 4 via a rotatable connection. 7. Based on the damping spring B406 installed on the outer wall of the guide column 404, and the effect of the damping spring B406 absorbing elevator vibration through elastic deformation, the two sets of track frames 4 on the car 2 are installed on the elevator track 1 respectively. The vibration isolation plate B402, together with the damping spring B406 and the damper B407, provides vibration isolation between the car 2 and the elevator track 1, and also ensures that the car 2 is in a centered and tilt-free state, so as to avoid the occurrence of vibration or wear caused by positional deviation between the car 2 and the elevator track 1, thereby reducing a certain elevator safety risk.

[0024] Working principle: When using this utility model, two sets of mounting brackets 3 are installed at the front and rear ends of the elevator track 1, and the output end of the damper A302 in the mounting bracket 3 is fixed to the vibration isolation plate A301. A damping spring A303 is installed between the vibration isolation plate A301 and the mounting bracket 3, so that the damping spring A303, in conjunction with the damper A302, enhances the vibration resistance and damping effect of the vibration isolation plate A301. This is achieved by sliding two sets of track brackets 4 on the outside of the elevator track 1. An array of rollers A304 is installed between the vibration isolation plate A301 and the track frame 4. An array of rollers B401 is also installed between the inner wall of the track frame 4 and the elevator track 1. This allows the vibration isolation plate A301 to clamp the track frame 4, and the rollers A304 ensure smooth movement of the track frame 4. Simultaneously, the rollers B401 on the inner wall of the track frame 4 prevent friction with the elevator track 1 and do not affect the smooth movement of the track frame 4. The two sets of vibration isolation plates B402 are connected by guide columns 404... The guide frame 403 is slidably connected to the track frame 4, and the damper B407 is installed between the vibration isolation plate B402 and the track frame 4 by rotational connection. The shock-absorbing spring B406 is fitted on the outer wall of the guide column 404, and the elastic deformation of the shock-absorbing spring B406 absorbs the vibration of the elevator. The two sets of track frames 4 on the car 2 are installed on the elevator track 1 respectively. The vibration isolation plate B402, together with the shock-absorbing spring B406 and the damper B407, provides vibration isolation between the car 2 and the elevator track 1, and also ensures that the car 2 is in a centered and tilt-free state, so as to avoid positional deviation between the car 2 and the elevator track 1, which may cause vibration or wear, and reduce the elevator safety risk. At the same time, the damper A302 and the shock-absorbing spring A303 provide vibration isolation for the outer periphery of the track frame 4, forming an internal and external vibration isolation effect, enhancing the stability between the elevator and the track, effectively improving the durability of the elevator track, and indirectly improving the safety and use effect of the elevator.
