Leveling mechanism
The invention discloses a leveling mechanism, and relates to the technical field of railway vehicles, the leveling mechanism comprises an inner sleeve and an outer sleeve, the outer sleeve is pre-buried and fixed in a floating slab arranged on a ballast bed, an internal thread is arranged in the outer sleeve, an external thread is arranged outside the inner sleeve, the external thread is in threaded connection with the internal thread, an adjusting part is arranged on the top surface of the inner sleeve, and the adjusting part is in threaded connection with the floating slab. The inner sleeve can be screwed through the adjusting part so that the inner sleeve can move up and down, and after the inner sleeve is screwed to move downwards to abut against the top face of a ballast bed, the inner sleeve continues to be screwed so that the height of the outer sleeve and the height of the floating slab can be adjusted. According to the leveling mechanism provided by the invention, the leveling working efficiency can be improved, the operation is simple, the adjusting precision is high, the maintenance is convenient, the corrugation phenomenon is reduced or avoided, the vibration noise is reduced or avoided, and the travel comfort is improved.
本发明公开了一种调平机构，涉及轨道车辆技术领域，包括内套和外套，所述外套预埋固定于置于道床上的浮置板内，所述外套内设有内螺纹，所述内套外设有外螺纹，所述外螺纹与所述内螺纹螺纹连接，所述内套顶面设有调节部，通过所述调节部能够拧动所述内套使所述内套上下移动，当拧动所述内套下移抵接道床顶面后，继续拧动所述内套以调节所述外套和浮置板的高度。本发明提供的调平机构，能够提高调平工作效率，操作简单，调节精度高，便于维护，减少或杜绝波磨现象的发生，降低了或杜绝了振动噪音的产生，增加了出行的舒适性。
