Problems solved by technology

However, since the damping body consumes rail vibration energy by generating shear-based resistance that is opposite to the forced direction of the vibration, its vibration and noise reduction performance and the contact area between the damping body and the rail, that is, the damping body withstands shear The actual working area of ​​the shear force is roughly proportional. For this reason, the planar plate damping material used in the above-mentioned patent is limited by the size of the rail waist, and the effective working area of ​​the damping material is limited, so the vibration and noise reduction effect it can achieve is also very limited, so this type of track cannot achieve the ideal vibration and noise reduction effect

Embodiment 1

[0031] Such as figure 1 , figure 2 The damping track of the present invention shown includes a track body 1, a damping body 2 made of high-damping rubber and a steel restraint body 3, and a steel connecting body 4 is also arranged between the track body 1 and the damping body 2 to connect The body 4 is multi-point welded to the non-working surfaces on both sides of the track body 1 by resistance welding. For the convenience of construction, the connecting body is divided into two sections for installation on each side of the track body according to its shape change. The connecting body 4 and the damping body 2 have a trapezoidal rib 5 on the side adjacent to the damping body 2, and the trapezoidal rib 6 interlaced with the connecting body trapezoidal rib 5 is arranged on the side adjacent to the damping body 2, and the damping body 2 It is arranged in the matching gap between the connecting body 4 and the constraining body 3, and the connecting body 4 and the constraining bo...

Embodiment 2

[0035] Such as image 3 , Figure 4 The vibration-damping track of the present invention shown includes a track body 1, a damping body 2 made of modified damping asphalt that is liquid at an operating temperature, and an aluminum alloy plate constraining body 3, and an aluminum alloy plate is also arranged between the track body 1 and the damping body 2. The connecting body 4 made of alloy is firmly bonded to the two sides of the rail body 1 by using a high-strength damping material. When bonding with high-strength damping materials, the bonding layer should be as thin as possible to ensure high bonding stiffness. The outer surface of the connecting body 4 has triangular ribs 5 , and the side of the constraining body 3 adjacent to the damping body 2 has triangular ribs 6 interlaced with the ribs 5 . The damping body 2 is arranged in the fitting gap between the connecting body 4 and the constraining body 3 . The restraint structure is locked on the rail by means of the groov...

Embodiment 3

[0039] Such as Figure 5 The vibration-damping track of the present invention shown includes a track body 1, a damping body 2 made of solid modified asphalt, and an aluminum profile constraining body 3, and an aluminum profile connecting body 4 is also arranged between the track body 1 and the damping body 2. The connecting body 4 is firmly bonded to the track body 1 by the elastic adhesive, and the ribs on the connecting body 4 cross-fit with the hollow rectangular bosses on the constraining body 3, and the damping body 2 is arranged between the connecting body and the constraining body within the fitting gap.

[0040] In order to facilitate the construction, the corresponding connecting body and restraining body are made in sections according to the shape of the rail. Since the space at the bottom of the rail is small and the plane area of ​​the rail bottom is large, the connecting body is omitted under the rail, and the connecting body is directly installed between the rest...

Abstract

The invention relates to a rail, especially steel rail for railway or electric trolley. Damp rail comprises rail body, on whose non-working surface connector with convex rib or convex-concave structure is set, constraint body connected with rail body, set corresponding to connector, whose inner surface processes convex rib or convex-concave structure and damping body, set between connector and constraint body or among connector, rail body and constraint body, forms labyrinth constraint damping structure, which is set continuously or distantly along length direction of rail body. The rail can decrease shake generated by rail and control the shake and noise of rail in original source, while alleviate availably steel and wheel attrition generated by liberative energy of rail shaking so that there is good damping and noise reduction effect, and operating life of wheel and rail, safety and amenity of train running is largely improved.

Description

technical field [0001] The invention relates to a rail, in particular to a steel rail used for railways or trams. Background technique [0002] With the rapid development of economic construction and transportation infrastructure construction, rail transportation methods such as subway, elevated light rail, ordinary railway and high-speed railway are playing an increasingly important role in the field of freight and passenger transportation because of their advantages of large carrying capacity, convenience, safety and reliability. role. How to reduce the noise pollution during rail transportation, reduce the vibration and wear of rails during transportation, thereby prolonging the life of the rail and improving the safety and comfort of rail transportation has become a difficult problem closely related to the production and life of the people and is increasingly being used. The attention of governments and scientific and technological workers in various countries. In the ...
