The invention discloses a hydraulic self-balancing lifting supporting seat. A U-shaped hydraulic groove is formed in a side supporting block; an external piston is arranged in a vertical part, far away from a lifting hydraulic cylinder, of the hydraulic groove in a vertically sliding manner; an internal piston is arranged in a vertical part, close to the lifting hydraulic cylinder, of the hydraulic groove in a vertically sliding manner; the external piston and the internal piston are correspondingly arranged to the internal side wall of the hydraulic groove in a sealed manner; an external supporting rod is molded on the external piston; the upper end of the external supporting rod vertically penetrates through the upper side wall of the hydraulic groove, and the side supporting block is hinged to the upper end of the external supporting rod; an internal supporting rod is molded on the internal piston; the upper end of the internal supporting rod vertically penetrates through the upperside wall of the hydraulic groove; the upper end surfaces of one pair of internal supporting rods are integrally connected with each other through a rectangular frame-shaped connecting frame; the space, between the external piston and the internal piston, of the same hydraulic groove is full of hydraulic oil; the external piston and the internal piston of the same hydraulic groove are integrally connected with each other through a steel wire rope at the center of the lower end surface of the same hydraulic groove, and the steel wire rope is always in a stretched state.

    本发明公开了一种液压自平衡的升降支撑座,侧支撑块内成型有U型状的液压槽;液压槽远离升降液压缸的竖直部内竖直滑行设置有外活塞、靠近升降液压缸的竖直部内竖直滑行设置有内活塞;外活塞和内活塞分别与液压槽内侧壁密封设置;外活塞上成型有外支撑杆;外支撑杆的上端竖直穿过液压槽的上侧壁并且铰接有侧支撑块;内活塞上成型有内支撑杆;内支撑杆的上端竖直穿过液压槽的上侧壁;一对内支撑杆的上端面通过矩形框状的连接框连成一体;同一液压槽位于外活塞和内活塞之间的空间内充满液压油;同一液压槽的外活塞和内活塞通过其下端面中心之间的钢丝绳连成一体并且钢丝绳始终处于拉紧状态。
