AI Technical Summary

Technical Problem

In the prior art, the laying method of the rail paving leads to unstable fixation of the rail, and the connection between the padding and the padding is not tight, affecting the stability and connection strength of the rail.

Method used

The triangular rail pad design is adopted. Each pad is connected to adjacent pads through drilling and bolts to form a triangle connection of 30° to 170°, increasing the number of connection points, and fixing it with multiple bolt holes. The padding material can be cinder or plastic, and is manufactured through neutron technology.

Benefits of technology

It improves the fixed stability and connection strength of the rail, reduces the dense distance of the padding, and enhances the overall stability and connection reliability of the rail.

Abstract

A triangular steel rail pad. Multiple pads are connected to form a triangle having angles ranging from 30° to 170°; holes (4) are drilled at the connection joints to accommodate bolts (5); and steel rails are mounted on the pads. The present invention is mainly used for enhancing the fixation and stability of steel rail mounting.

Description

Triangular bedding for rail installation

[0001] Technical Field: The invention relates to a method for placing rails on triangular mats, forming a 30° to 170° angle. Two mats are marked with lines between 24.5 cm and 280 cm on each end. The two halves, each 20 cm to 28 cm thick, are joined to form a triangular mat. This is then extended indefinitely to form a rail connection or chain. The main mat, rail, and rail sides are integrally bolted together using bolt holes.

[0002] Background: Current technology uses a straight-line bedding system, arranged horizontally in the direction of the rail. Bedding is separated from each other, and two beddings are bolted together using eight bolt holes, rather than forming a triangle. The bolt holes are estimated to be 22 to 28 cm long. The bedding is 240 to 242 cm long, with a top width of approximately 17 cm and a bottom width of approximately 23 cm.

[0003] Invention Summary: The goal is to reduce the density of existing mats and increase the sparseness of rail installation with a new mat. This creates a triangle with an apparent angle of 30° to 170°. Three to six bolt holes are used for bolting. Two mats are joined, each with a horizontal line of 24.5 to 280 cm. The sides, each half with a thickness of 20 to 28 cm, are joined to form a triangle, extending indefinitely and connected or linked by rails.

[0004] Specific implementation: Each mat is approximately 240 cm long, 15 cm wide at the top, and 23 cm at the bottom. The thickness is approximately 25 cm. Each mat is placed on the rail, and a groove is drawn parallel to the rail surface, 2 to 3 cm deep. Three or more mats are bolted together using the bolt holes, with 3 to 6 bolts.

[0005] The bedding material is supposed to be made of coal slag or coal, plastic or plastic through "neutron" technology. If "neutron" technology cannot be found, the existing bedding technology materials will be used.

[0006] The pad and rail are both “-” body and drilled once.

[0007] The data between the two sides of the rail position security is existing technology.

[0008] The bolt hole is estimated to be 22 to 28 cm.

Claims

1. Draw a horizontal line at 24.5 to 28 cm on the top surface of each piece or mat, and combine the two halves at 20 to 28 cm in thickness, and extend the connection indefinitely to form a 30° to 170° triangular mat.

2. 3 or 3 pads and rails are placed together using 3 to 6 bolts.

3. The bedding is made of coal slag or coal plastic or waste plastic through "neutron" technology or adding adhesive.
