TECHNICAL FIELD
[0001] The utility model relates to railway track accessory technical field especially relates to a special-shaped rail rail rubber pad. BACKGROUND
[0002] In the field of rail transit, special-shaped rails meet the special needs of specific lines with their unique structure, effectively improving the adaptability of the rail system to complex terrain and running scenarios, and ensuring the stable operation of trains. The rail rubber pad, as a key component of the rail structure, is laid between the special-shaped rail and the sleeper, playing an important role in buffering and shock absorption, insulation and noise reduction, and protecting the rail and sleeper. It is crucial to prolong the service life of the rail component and improve the comfort of train travel.
[0003] Currently, the special-shaped rail rubber pad on the market has some products that use bolt and nut splicing to connect the pads in the structural design. Although this achieves a firm effect, it is still relatively troublesome to install, as the construction personnel need to repeatedly twist the bolts when splicing, resulting in slow progress in laying. In terms of shape and structure, many pads have smooth tops. When the train passes, the concentrated stress will continue to act on the edge of the pad, causing the edge of the pad to be easily crushed and damaged, which seriously affects the service life of the pad. Therefore, a special-shaped rail rubber pad is proposed to solve the above problems. SUMMARY
[0004] To make up for the above shortcomings, the utility model provides a special-shaped rail rubber pad, aiming to improve the low splicing efficiency and the problem of edge crushing in the prior art.
