Description

Technical Field

[0001] The present application relates to the field of vibration isolators, and in particular to a compression type rubber vibration isolator structure for high-speed trains. Background Art

[0002] Rail transit, as the most modern, convenient and environmentally friendly mode of travel, has been rapidly developed on a large scale. However, no matter which type of rail transit people use, it will produce annoying vibrations and noise. In countries with existing cities with subways, there will undoubtedly be situations where the subway is close to buildings or even directly passes under buildings. In this case, once the subway passes through nearby buildings, it will be disturbed by strong vibrations and noise, which will have a certain impact on the lives of residents along the line and the building structures. Rubber isolators are mainly placed on both sides of the track. When the subway passes by, it plays a role in buffering, adjusting the subway frequency and absorbing energy. The purpose is to prevent the subway from generating huge vibrations during operation and transmitting them to the ground through the tunnel wall, thereby affecting the buildings and residents' lives on the ground.

[0003] The structure of the product can refer to a compression type rubber isolator structure for high-speed trains disclosed in Chinese patent document 2021 11451636.4, which relates to the technical field of vibration isolation and buffering devices, specifically a compression type rubber isolator structure for high-speed trains, including a track, a pad is fixedly installed at the bottom of the track, and first support columns are fixedly installed on both the left and right sides of the pad, and the outer end of the first support column is fixedly connected to a first limit block, and first buffer springs are fixedly installed on both the left and right sides of the pad. The compression type rubber isolator structure for high-speed trains can improve the shock absorption performance of the device by providing a second rubber filling pad between the track, the first metal cover, and the second metal cover, and providing a first rubber filling pad between the mounting frame, the first metal cover, and the second metal cover, while preventing the shock absorbing plate from being subjected to a large load, resulting in wear between the track, the mounting frame, the first metal cover, and the second metal cover, resulting in a problem of reduced service life.

[0004] Train isolators need to be installed between the bridge deck and the bridge piers to reduce the vibration generated when the train passes through the bridge and reduce damage to the bridge. However, the overall connection stability of the isolators in this patent is poor.

[0005] A compression type rubber isolator structure for high-speed trains is now provided. Summary of the invention
