Aforesaid hydraulic pressure rail jack, described first oil feed line that raises track the execution oil cylinder and the second track lifting execution oil cylinder is fixed on the underframe.
Aforesaid hydraulic pressure rail jack is provided with oil supply gallery in the described underframe, and oil cylinder is carried out in above-mentioned first track lifting and the second track lifting execution oil cylinder is connected underframe oil supply gallery and oil cylinder respectively with the bearing pin that underframe is hinged.
Aforesaid hydraulic pressure rail jack, described first oil feed line that raises track the execution oil cylinder and the second track lifting execution oil cylinder is fixed on the underframe.
Aforesaid hydraulic pressure rail jack is provided with oil supply gallery in the described underframe, and oil cylinder is carried out in above-mentioned first track lifting and the second track lifting execution oil cylinder is connected underframe oil supply gallery and oil cylinder respectively with the bearing pin that underframe is hinged.
The hydraulic pressure rail jack that the utility model proposes, because being provided with two one ends on underframe is hinged, oil cylinder is carried out in the first hinged track lifting of the other end and underframe and oil cylinder is carried out in second track lifting, this two oil cylinder and underframe constitute a triangle, when the track lifting operation, the operator is by the control hydraulic control device, the high-pressure and hydraulic oil that this hydraulic control device is produced enters the track lifting oil cylinder, the piston rod of two oil cylinders stretches out simultaneously, forms leg-of-mutton two limits and extends simultaneously, realizes that two oil cylinder hinged places are mobile vertically upward, rail is lifted, finish the track lifting operation, it only is a side cylinder start that the utility model has overcome known configurations, the defective of track lifting quantity not sufficient, structure of the present utility model is not increasing equipment volume, under the situation of weight, the track lifting amount is significantly improved, improved efficiency greatly, alleviated labour intensity.
