Abstract
Description
Technical Field
[0001] The utility model relates to the field of tracks, in particular to a double-block sleeper. Background Art
[0002] In railway construction, double-block sleepers are an important part of ballastless tracks, and their design is directly related to the stability and durability of the track and the safety and comfort of train operation. The double-block sleepers widely used in the current market are mostly made of precast concrete blocks connected to rails through a fastener system. While this structure provides good bearing capacity, it also exposes some shortcomings. For example, the adaptability and stability of traditional designs need to be improved when dealing with track expansion and contraction caused by extreme temperature changes; in addition, traditional double-block sleepers have limited noise reduction effects and are difficult to meet the growing environmental protection and comfort requirements, so we need a double-block sleeper to solve the above problems. Utility Model Content
[0003] The purpose of the utility model is to provide a double-block sleeper, which solves the problems in the above-mentioned background technology.
[0004] The utility model is implemented in this way. A double-block sleeper comprises: a sleeper body, wherein the upper surface of the sleeper body is provided with two protrusions, a groove is provided between the two protrusions, a through hole is provided on the groove, and the through hole penetrates the sleeper body from top to bottom.
[0005] A further technical solution of the utility model is: the sleeper bodies are provided with two and correspond to each other, and a steel pipe connecting piece is provided between the sleeper bodies.
[0006] A further technical solution of the utility model is that a long groove is provided on the side of the sleeper body.
[0007] A further technical solution of the utility model is that the width of the groove is smaller than the sum of the widths of the two protrusions.
[0008] A further technical solution of the utility model is that a composite elastic pad is arranged in the long groove.
[0009] A further technical solution of the utility model is that the sleeper body is composed of steel bars and concrete.
[0010] The beneficial effects of the utility model are as follows: the utility model has a simple structure and is easy to use. Through the setting of the through hole, the flowing wind is diverted to the bottom, which reduces noise, greatly reduces the vibration and noise during train operation, improves the riding comfort of passengers, and reduces the impact on the surrounding environment. The setting of the composite elastic pad in the long groove can prevent the sleeper body from causing excessive damage when subjected to force, greatly increases the service life of the sleeper body, and saves costs.

[0017] Embodiment 1: Figures 1-3 Shows a double-block sleeper, including: a sleeper body 1, two protrusions 4 are provided on the upper surface of the sleeper body 1, a groove 3 is provided between the two protrusions 4, a through hole 2 is provided on the groove 3, and the through hole 2 penetrates the sleeper body 1 from top to bottom. Two sleeper bodies 1 are provided and correspond to each other, and a steel pipe connector 5 is provided between the sleeper bodies 1. A long groove 6 is provided on the side of the sleeper body 1. The width of the groove 3 is smaller than the sum of the widths of the two protrusions 4. A composite elastic cushion block is provided in the long groove 6. The sleeper body 1 is composed of a combination of steel bars and concrete.
[0018] The utility model has a simple structure and is convenient to use. Through the arrangement of through holes, part of the fast-flowing wind is diverted to the lower part, reducing noise, significantly reducing the vibration and noise during the train operation, improving the riding comfort of passengers, and at the same time reducing the impact on the surrounding environment. The arrangement of the composite elastic cushion blocks in the long strip grooves can prevent excessive damage to the sleeper body when it is stressed, greatly increasing the service life of the sleeper body and saving costs.
[0019] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
