Abstract
The invention discloses a base plate used for installing a sleeper in a cushioning mode. The base plate used for installing the sleeper in the base mode comprises a plate body which is arranged on the lower surface of the sleeper in a matched and cushioning mode, wherein a plurality of horizontal strip-shaped concave grooves which are evenly distributed at intervals are horizontally formed in the upper surface of the plate body, and a plurality of vertical strip-shaped concave grooves which are evenly distributed at intervals are vertically formed in the lower surface of the plate body. Among the plurality of horizontal strip-shaped concave grooves and the plurality of vertical strip-shaped concave grooves, and the length of each of the horizontal strip-shaped concave grooves and/or the vertical strip-shaped concave grooves located in the middlemost portion is larger than that of each of the horizontal strip-shaped concave grooves and/or the vertical strip-shaped concave grooves located at two sides. A plurality of base feet, which are far away from the plurality of horizontal strip-shaped concave grooves and the plurality of vertical strip-shaped concave grooves and are fixedly connected with the plate body, are arranged on the lower surface of the plate body, and a pair of lateral fixtures, which are used for being fixedly connected with the sleeper and are fixedly connected with the plate body, are symmetrically arranged on a pair of lateral edges of the plate body. The base plate used for installing the sleeper in the cushioning mode has the advantages of being good in shock-absorption effect, even in stress dispersion, long in service life, energy-saving and environment-friendly.
Description
Technical field
The present invention relates to the railway casting technical field, particularly, relate to a kind of backing plate for pad dress sleeper.
Background technology
Usually; in the concrete sleepers such as railway, high-speed railway, city sleeper traffic; generally need to usually adopt resilient sleeper-bearing between sleeper (as rail or rail) and sleeper; with absorb vehicle by the time vibrational energy that produces; the noise pollution that damping vibration brings, and protect to a certain extent sleeper.
But above-mentioned resilient sleeper-bearing is mostly rubber tile, and temperature influence is larger, and relatively poor to the protection effect of sleeper, application life is short, reclaims also inconvenient.If adopt thermoplastic elastomer (s) to make resilient sleeper-bearing, although can overcome the larger defective of rubber tile temperature influence, because the groove of this backing plate has wedge angle, make this backing plate stress dispersion when stressed uneven, thereby also affected application life.
In realizing process of the present invention, the inventor finds to exist at least in prior art the defective such as effectiveness in vibration suppression is poor, stress dispersion is inhomogeneous, application life is short and environmental protection and energy saving is poor.
