Description

Technical Field

[0001] This utility model relates to the field of floating slab track technology, specifically a vibration-damping floating slab track. Background Technology

[0002] Floating slab track is a special type of rail transit structure. Its basic principle involves placing vibration isolation elements, such as rubber or steel springs, between the slab or beam-type monolithic track bed and the track foundation. This forms a mass, spring, and damping system. When a train runs on the track, the vibration energy generated between the wheels and rails is transferred to the track bed. The vibration isolation device uses its own elastic deformation to absorb and isolate these vibrations, achieving vibration reduction and noise reduction. In subway systems, floating slab tracks are widely used to reduce the impact of vibration and noise on the surrounding environment and residents. This is especially important in situations with special requirements for vibration and noise reduction, such as hospitals, research institutes, museums, and other areas sensitive to vibration and noise. To achieve the effect of track vibration reduction and noise reduction, a floating slab track is needed. However, existing floating slab tracks still have the following shortcomings:

[0003] When existing floating slab tracks are in use, most floating slab tracks only increase the vibration reduction and isolation effect during track use through a single structure. However, vibration occurs in rail transit at all times. A single vibration reduction and isolation structure may not achieve the purpose and effect of vibration reduction and isolation during use, resulting in a decrease in the practicality and efficiency of floating slab tracks. Utility Model Content

A first track slab is provided on the upper left side of the track bed, and a second track slab is connected to the outside of the first track slab. A vibration-damping assembly is provided on the outside of the first track slab, and the vibration-damping assembly includes a mounting base, a receiving groove, a vibration-damping pad, a rail body, a mounting groove, and a steel spring body. A receiving groove is provided in the middle of the mounting base, and a vibration-damping pad is provided inside the receiving groove. A rail body is connected to the upper end of the mounting base. A mounting groove is provided inside the first track slab, and a steel spring body is provided inside the mounting groove. An mounting assembly is provided on the outside of the first track slab.

[0006] Furthermore, the internal dimensions of the receiving groove are adapted to the external dimensions of the shock-absorbing pad, and the shock-absorbing pad is connected to the mounting base through the receiving groove.

[0007] Furthermore, the number of steel spring bodies is set to six, and three steel spring bodies are grouped together. Each group of steel spring bodies is symmetrically arranged on both sides of the interior of the first track plate with respect to the central axis of the front of the first track plate.

[0008] Furthermore, the steel spring body is embedded in the mounting groove, and the steel spring body and the mounting groove are fixedly connected by bolts.

[0009] Furthermore, the installation assembly includes an installation docking groove, an installation docking block, and a docking mortise. The installation docking groove is internally connected to the installation docking block, and the second track plate has a docking mortise at its center.

[0010] Furthermore, the mounting assembly also includes a tenon, a threaded groove, and a mounting bolt, with the tenon connected inside the mortise and the threaded groove having a threaded groove on the left end inside the second track plate, and the mounting bolt connected inside the threaded groove.

[0011] Furthermore, the internal dimensions of the mounting docking groove are adapted to the external dimensions of the mounting docking block, and the mounting docking block is embeddedly connected to the second track plate through the mounting docking groove.

[0015] 2. This utility model, through the setting of the installation components, enables the installation docking block and docking tenon to be fixedly installed on the outer rear end of the first track plate by fastening bolts when the vibration-damping floating slab track is in use.

The mounting base 401 is fixedly installed on both sides of the upper end of the first track plate 2 by tightening the bolts. The internal dimensions of the receiving groove 402 opened inside the mounting base 401 are adapted to the external dimensions of the shock-absorbing pad 403, so that the shock-absorbing pad 403 is installed into the mounting base 401 through the receiving groove 402. The rail body 404 is installed on the upper end of the mounting base 401 by bolts. The mounting base 401 is equipped with internal features. The shock-absorbing pad 403 performs shock absorption on the rail body 404. The steel spring body 406 is fixedly installed in the mounting groove 405 opened at the lower end of the first track slab 2. At the same time, the bottom of the steel spring body 406 is fixedly installed to the upper surface of the track bed 1, and the upper end of the steel spring body 406 is fixedly installed to the upper end of the mounting groove 405. This allows the first track slab 2 to be connected to the track bed 1 by the steel spring body 406, thereby further increasing the shock absorption effect during the use of the floating slab track and further improving the overall vibration isolation performance of the floating slab track.

[0022] like Figures 1 to 3As shown, the first track plate 2 is externally equipped with an installation component 5, which includes an installation mating groove 501, an installation mating block 502, and a mating mortise 503.
