The invention discloses a hydraulic lifting trolley for loading, unloading and transporting rolling mill bearings. The hydraulic lifting trolley comprises a trolley frame, the trolley frame is of a frame structure, a vertically-arranged hydraulic oil cylinder is installed at the rear end of the trolley frame, and the hydraulic oil cylinder is vertically upward; the top end of a piston rod is connected with a bearing supporting rod through a connecting piece, and the bearing supporting rod faces the front end of the trolley frame and is used for being arranged in a bearing inner ring in a penetrating mode; the front end of the bearing supporting rod protrudes upwards to form a limiting protruding edge, and the limiting protruding edge is used for clamping a bearing arranged on the bearing supporting rod in a sleeving mode so as to prevent the bearing from slipping; and wheels are arranged at the bottom of the trolley frame; by changing the loading and unloading mode and the conveying mode of the bearing, the labor intensity is reduced, the assembling and disassembling time is saved, and the safety risk existing in the assembling, disassembling and conveying process is reduced.

    本发明公开了一种用于轧机轴承装卸运输的液压升降小车,包括车架,车架为框架结构,且其后端安装有竖直设置的液压油缸,液压油缸的竖直朝上;活塞杆的顶端通过连接件连接有轴承支撑杆,轴承支撑杆朝向车架的前端,轴承支撑杆用于穿设在轴承内环中;轴承支撑杆的前端向上凸起有限位凸沿,限位凸沿用于卡住套在轴承支撑杆上的轴承,以防止其滑脱;车架的底部设置有车轮;本发明实施例通过改变轴承的装卸方式和运送方式,降低劳动强度,节约装配拆卸时间,减少在装配拆卸运输过程中存在的安全风险。
