Wherein, the lifting component 2 and the driving component 3 are both arranged on the supporting table 11. Therefore, in the place inconvenient for the crane to enter, the supporting table 11 and the supporting legs 14 can be disassembled and then transferred to the cable well cover, so that the device can conveniently enter a narrow working environment. During assembly, the insert rod 15 on the support table 11 is placed into the slot 13 of the support leg 14, so that the support table 11 and the support leg 14 are connected.
