The invention discloses a hydraulic jack for cover opening and core suspending of a transformer. The hydraulic jack comprises a supporting seat, a hydraulic cylinder, an upper clamping assembly, and alower clamping assembly, wherein the hydraulic cylinder is arranged on the supporting seat, a piston rod of the hydraulic cylinder faces upwards, and a vertical adjusting rod is movably connected tothe outer end of the piston rod; the upper clamping assembly is arranged on the vertical adjusting rod and can move up and down under driving of the vertical adjusting rod, and is used for clamping anupper cover of the transformer; and the lower clamping assembly is arranged on the portion, located below the upper clamping assembly, on the supporting seat, and is used for clamping a lower cover of the transformer. The two hydraulic jacks are needed to be arranged on the two sides of the transformer at the same time in use, and the two upper clamping assemblies synchronously lift, so that cover opening and core suspending are completed; and the above hydraulic jack for cover opening and core suspending of the transformer selects the hydraulic cylinder for driving, the structure is simple,and the operation process is controlled easier.
本发明公开了一种用于变压器开盖吊芯的液压千斤顶,包括:支撑座;液压缸,其设置在所述支撑座上,所述液压缸的活塞杆朝上,且所述活塞杆外端活动连接有竖向调节杆;上夹持组件,其设置于所述竖向调节杆上,且可在所述竖向调节杆的带动下上下移动,用于对变压器上盖进行夹持;下夹持组件,其设置于所述支撑座上且位于所述上夹持组件的下方,用于对变压器下盖进行夹持。使用时,需同时将两个上述液压千斤顶分别设置于变压器两侧,两个上夹持组件同步升降,由此完成开盖吊芯。上述用于变压器开盖吊芯的液压千斤顶选择液压缸进行驱动,结构简单且操作过程更容易控制。
