Embodiment 1

[0026] see Figure 1~3 , in an embodiment of the present invention, an integrated railway track bed with good shock absorption, comprising a sleeper 2, rails 1 are arranged on both sides above the sleeper 2, and rails 1 are fixedly connected to the sleeper 2 on both sides of the bottom of the rail 1 The installation block 19, the installation block 19 is provided with the installation bolt 3 that runs through the installation block 19; the position of the sleeper 2 corresponding to the installation bolt 3 is provided with a bolt hole 18; the bolt hole 18 and the installation bolt 3 are provided with The rail buffer mechanism, the rail buffer mechanism includes six mounting holes 20 evenly arranged in the bolt holes 18, the bottom of the mounting holes 20 is fixedly connected with a rail buffer spring 21, and the other end of the rail buffer spring 21 is connected to the The elastic shaft 22 is fixedly connected. When the train is running, it first contacts with rail 1, so the...

Embodiment 2

[0033]In this embodiment, a further improvement is made on the basis of Embodiment 1, and the improvement content is: a water channel 9 is provided at the bottom of the base 6 , and a water leakage port 11 is provided at the center of the base 6 . When running into rainy and snowy weather, sewage will enter inside the base, and the sewage will cause parts such as connecting rods and cross bars to corrode, thereby reducing their service life. And setting water channels and water leaks at the bottom can discharge it from the inside of the base in time, thereby avoiding parts from rusting.

[0034] To sum up, the working principle of the present invention is as follows: when the train is running, the train first passes the rail 1, and the rail 1 transmits the vibration to the mounting block and the mounting bolt, and the vibration is weakened for the first time by the rail buffer mechanism. Then the vibration is transmitted from the sleeper 2 to the base plate 4 and weakened for ...

Abstract

The invention discloses a railway monolithic track bed with good shock absorption performance. The railway monolithic track bed comprises a sleeper, wherein rails are arranged on the two sides of theupper portion of the sleeper, installation blocks fixedly connected with the sleeper are arranged on the two sides of the bottom of each rail, and installation bolts penetrating through the installation blocks are arranged on the installation blocks; bolt holes are formed in the positions, corresponding to the installation bolts, of the sleeper; and rail buffer mechanisms are arranged between thebolt holes and the installation bolts, each rail buffer mechanism comprises six installation holes uniformly formed in the corresponding bolt hole, rail buffer springs are fixedly connected to the bottoms of the installation holes, and the other ends of the rail buffer springs are fixedly connected with elastic shafts. Compared with a traditional railway track bed, the railway monolithic track bedis more remarkable in shock absorption effect, so that a train runs more safely.

Description

technical field [0001] The invention relates to the field of technical railway equipment, in particular to an integrated railway track bed with good shock absorption. Background technique [0002] The track bed is an important part of the track and the foundation of the track frame. The track bed usually refers to the stone ballast cushion layer laid on the subgrade surface under the railway sleeper. The main function is to support the sleeper, transmit the huge pressure on the upper part of the sleeper to the roadbed surface evenly, and fix the position of the sleeper, prevent the sleeper from moving longitudinally or laterally, greatly reduce the deformation of the roadbed, and at the same time ease the impact of the rolling stock wheel on the rail, which is convenient drain. However, the traditional integral track bed of railways has poor shock absorption effect, which brings safety hazards to train running. Contents of the invention [0003] The purpose of the prese...
