Problems solved by technology

[0002] my country's rail transit has a large freight volume and a large part of the domestic track forms are ballast bed tracks. In order to improve the problems of ballast pulverization and ballast bed deformation, the existing technology adopts the method of adding sleeper pads under the sleepers to improve the above problems. Sleeper pads have a limited life cycle and must be replaced within a certain period
Due to the way of adding sleeper pads in the existing technology as an integrated embedding method, the corresponding sleeper needs to be replaced and scrapped every time the sleeper pad is replaced, which not only wastes labor costs, but also causes a great waste of other resources

Embodiment Construction

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] like Figure 1 to Figure 3 A sleeper with a replaceable sleeper pad is shown, including a sleeper 1 and a replaceable sleeper pad 2 matched with the sleeper 1, and the bottom of the sleeper 1 is fitted and fixed with the replaceable sleeper pad 2 ; On the side of the replaceable sleeper pad 2 connected to the bottom of the sleeper 1, there are adhesion protrusions 21, transverse limit protrusions 22 and longitudinal limit protrusions 23; the bottom of the sleeper 1 is provided with There are adhesive grooves, transverse limiting grooves and longitudinal limiting ...

Abstract

A sleeper with an exchangeable sleeper pad comprises a sleeper and an exchangeable sleeper pad matched with the sleeper. The bottom of the sleeper is fixedly applied to the exchangeable sleeper pad; one surface of the exchangeable sleeper pad connected with the bottom of the sleeper is provided with adherent projections, transverse spacing projections and longitudinal spacing projections; the adherent projections, transverse spacing projections and longitudinal spacing projections are respectively embedded into adherent grooves, transverse spacing grooves and longitudinal spacing grooves; and the transverse and longitudinal spacing projections are arc-shaped curve projections in different directions. Problems of railway ballast, road bed deformation, sleeper pad exchange and sleeper circulating use can be solved; and the transverse and longitudinal spacing projections are arc-shaped curve projections in different directions, so shear-bearing capacity of the transverse and longitudinal spacing projections can be increased.

Description

technical field [0001] The invention relates to the technical field of railway traffic, in particular to a sleeper with replaceable sleeper pads. Background technique [0002] my country's rail transit has a large freight volume and a large part of the domestic track forms are ballast bed tracks. In order to improve the problems of ballast pulverization and ballast bed deformation, the existing technology adopts the method of adding sleeper pads under the sleepers to improve the above problems. Sleeper pads have a limited life cycle and must be replaced within a certain period. Because the way of adding sleeper pads in the prior art is integrated and embedded, each time the sleeper pads are replaced, the corresponding sleepers also need to be replaced and scrapped, which not only wastes labor costs, but also causes a great waste of other resources. Contents of the invention [0003] The purpose of the present invention is to design a new type of sleeper with replaceable sl...
