Problems solved by technology

[0006] The existing one-shaped railway sleepers are fragile in terms of track safety due to the weak lateral and longitudinal resistance of the ballast bed, resulting in line swelling, which will threaten the safety of train operation, etc.
[0007] In the case of the existing multi-branch type railway sleepers, firstly, there are disadvantages such as difficulty in manufacture because of its very complicated shape, and the disadvantage of increased manufacturing cost; Finally, due to the lack of water drainage due to the horizontal sleeper seats on both sides of the central connection seat, there are many maintenance problems such as line sinking
[0008] In addition, because the existing railway sleepers are in-line, there are many line distortions and track deviations, and maintenance is difficult. This is the main cause of poor ride comfort. The distortion phenomenon is caused by the three-point support phenomenon of the train bogie Problem with trains running off the line
[0009] The Japanese Open Utility Model Gazette No. 50-148702 (1975.12.10 open) sleepers due to poor drainage, aggravate the generation of muddy mud, cause track deviation and need frequent maintenance, so can not fully play the function as sleepers
In addition, due to the difficulty in the operation of large-scale mechanical maintenance devices such as compound ramming machines, ballast cleaning machines, and ballast ramming machines, it is considered that sleepers are not economical

Embodiment 1

[0065] Embodiment 1 relates to the railway H-type crossties of the present invention.

[0066] figure 1 It shows the installation drawing of the embodiment 1 where the rail is installed, figure 2 express figure 1 The up-and-down cross-sectional view of , image 3 Representing the perspective view of Embodiment 1, Figure 4 Represent the plan view of embodiment 1, Figure 5 express Figure 4 The AA' section diagram of Image 6 express Figure 4 The BB' cross-sectional view of Figure 7 express Figure 4 The CC' cross-section.

[0067] refer to figure 1 and figure 2 , The railway tie T of Embodiment 1 is set on the lower part of the rail 100 . The top surface of the railroad tie T is exposed, surrounded by ballast gravel P, and buried.

[0068] refer to image 3 , The railway tie T is formed to form an H shape. The railway tie T includes two inline main supports 200 and a ballast gravel resistance plate 300, and the two inline main supports 200 are separated fro...

Embodiment 2

[0083] Embodiment 2 relates to yet another railway H-type sleeper of the present invention.

[0084] Figure 8 Represents the plan view of embodiment 2, Figure 9 The setup diagram of Example 2 is shown.

[0085] refer to Figure 8 and Figure 9 , Embodiment 2 is the same as Embodiment 1, including two main supports 200 and a ballast gravel resistance plate 300 .

[0086] refer to Figure 8 and Figure 9 , any one of the two main supports 200 is protrudingly formed with a movement preventing protrusion 700 . The anti-movement protrusion 700 protrudes along the longitudinal direction of the rail 100 on the outer surface in the width direction of the main support 200 , and is formed so as to be located on the longitudinal extension of the ballast gravel resistance plate 300 . When the railroad tie T is installed, the anti-movement protrusion 700 contacts or connects with the main support 200 of the railroad tie T arranged adjacent to each other.

[0087] The anti-movement ...

Abstract

The present invention relates to a railroad tie, and to a mold for manufacturing same. More particularly, the present invention relates to an H-shaped railroad tie produced from prestressed concrete (PC) and reinforced concrete (RC), wherein a railway ballast resistant board is installed at the center of the railroad tie, a rail support is formed into a flat form, and a rail is installed in parallel to each rail support to prevent the deviation of the railroad track. The railroad tie of the present invention has an enhanced shape and structure for reinforcing rail tracks to remarkably improve train operating safety.

Description

technical field [0001] The present invention relates to a railway sleeper and a mold for manufacturing the railway sleeper, more particularly to a railway H-type sleeper and a mold for manufacturing the railway H-type sleeper. The railway H-type sleeper is made of PC (prestressed concrete, prestressed concrete) and RC (Reinforced Concrete), set the ballast gravel resistance plate in the center, make the rail seat flat, set the rails to be horizontal to each rail seat, prevent track deviation, and strengthen by improving the shape and structure line, significantly improving the safety of train operation. Background technique [0002] Railway sleepers are wooden or concrete sleepers that are laid on the lower part of the rails to fix the rails at a specified position on the track and spread the weight of the train on the rails widely to the track bed. [0003] Here, the railway sleepers are generally formed in a straight line, and most of them are arranged in multiples along ...
