Embodiment Construction

[0028] Below by specific embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0029] Such as figure 1 and figure 2 Shown: a backing plate 1 for a composite sleeper, comprising an upper part and a lower part, the upper part is a connection layer connected with the sleeper, the lower part is a vibration-damping layer 11, and the connection layer and the vibration-damping layer 11 One-piece molding by vulcanization. When installing the under-pillow pad, various cumbersome processes such as gluing, drying, and bundling are no longer required, which reduces costs and improves production efficiency.

[0030] The connecting layer is a combination of various fiber filaments or various metal filaments, or a combination of various fiber filaments and various metal filaments. The fiber filament is any one or a combination of several of nylon fiber, polyester fiber and other polymer fibers, and the fiber filament has strong corros...

Abstract

The invention provides a composite under-sleeper cushion plate, which comprises a vibration reduction layer and a connecting layer, the connecting layer is made of fiber yarns and / or metal wires, andthe connecting layer and the vibration reduction layer are integrally formed through vulcanization. The invention further provides a sleeper. The composite sleeper lower base plate is fixed below thesleeper. When the sleeper is prefabricated, the connecting layer of the under-sleeper base plate and the sleeper are solidified into a whole in advance. The connection reliability of the under-sleeperbase plate and the sleeper is good. When the sleeper is installed, multiple tedious procedures of gluing, drying, binding and the like are not needed any more, the construction difficulty and the construction cost are reduced, and the installation efficiency is improved.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a composite pillow underlay plate and a sleeper thereof. Background technique [0002] With the development of the economy, heavy-duty lines are required to meet the operation of large axle load, high density and high speed, and the requirements for track lines are also getting higher and higher. Ordinary lines can reduce the impact of vehicles on the track and roadbed by adding ballast. To achieve the purpose of vibration reduction, but due to factors such as inconvenient construction and limited bearing capacity of tunnels and bridges, it is impossible to lay a large amount of ballast at the same time. Therefore, in order to reduce the impact of vehicles on bridges and tunnels, the rubber pillow under the pad is usually used to increase elasticity. Reduce stiffness to meet track line requirements. [0003] When laying under-pillow backing boards, the under-pillow backing boa...
