The invention relates to the technical field of rail transit, and discloses equipment for overhauling the rail levelness by level bubbles. The equipment includes a housing, a liquid mixing bag is fixedly connected to the interior of the housing, a liquid feeding pipe is fixedly connected into the liquid mixing bag, a liquid flow groove is fixedly connected to the bottom of the liquid mixing bag, aliquid level cylinder is fixedly connected to the bottom of the liquid flow groove, a spring rod is movably connected to the bottom of the liquid level cylinder, a threaded pipe is movably connectedto the lower end of the spring rod, and a cam shaft is movably connected to the upper end of the threaded pipe. Therefore, the pressure in the liquid level cylinder is increased, the liquid mixing bagcontracts inwards and applies a certain pressure to the surface of the liquid feeding pipe, liquid with a small viscosity coefficient is extruded and flows in the liquid mixing bag, due to the fact that the elastic force of the spring rod is mutual, the surface of the liquid mixing bag is subjected to intermittent pressure, namely, the liquid in the liquid mixing bag is evenly mixed, the mixed liquid flows into the liquid level cylinder from the liquid flow groove, and the effect of detecting the rail levelness through level bubbles is achieved.
本发明涉及轨道交通技术领域,且公开了一种利用水准气泡检修轨道水平度设备,包括壳体,所述壳体的内部固定连接有混液囊,混液囊的内部固定连接有送液管,混液囊的底部固定连接有液流槽,液流槽的底部固定连接有液位筒,所述液位筒的底部活动连接有弹簧杆,弹簧杆的下端活动连接有螺纹管,螺纹管的上端活动连接有凸轮轴。故液位筒内部的压力变大,故混液囊向内收缩并在送液管表面施加一定的压力,故粘滞系数较小的液体的被挤压出来,并流在混液囊内部,由于弹簧杆的弹力为相互的,故混液囊表面受到间歇压力,即内部的液体混合均匀,混合后的液体从液流槽流至液位筒内部,从而达到了利用水准气泡检测轨道水平度的效果。
