The invention discloses a hydraulic support used for supporting and protecting a non-conventional type roadway, which comprises a base, a hydraulic extension upright post arranged on the base, a top beam arranged on the top of the hydraulic extension upright post and a shield beam connected with the back of the top beam; the lower part of the shield beam is hinged with the base via a connecting rod; the top of the hydraulic extension upright post is hinged with the top beam axle hole via a cross axle cap; the back of the top beam is hinged with the top of the shield beam via a cross hinge axle bed. The hydraulic support has the advantage of hinging the back of the top beam and the top of the shield beam via the cross articulated axle bed and the articulated axle and hinging the top of the hydraulic extension upright post and the top axle hole via the cross jack post cap. Therefore, the top beam can rotate along both the horizontal axle and the vertical axle of the cross articulated axle; at the same time, the between part of the hydraulic extension upright post and the top beam can swing in any direction and bear load to support the top beam. In this way, the top beam of the hydraulic support can adjust and support the top plate along the changes of the vertical and the horizontal inclinations of the top plate.
