Referring to fig. 1, the present embodiment provides an auxiliary lifting device for power transformation maintenance, which includes a device bottom plate 1, a scissor-type hydraulic lifter 2 and a manned platform 3;
the auxiliary lifting equipment for power transformation maintenance further comprises two area extension structures 4, a guardrail 5, a shielding mechanism 6, a cooling mechanism 7 and the like.
The scissor type hydraulic lifter 2 is movably assembled on the equipment bottom plate 1; the manned platform 3 is movably assembled at the top end of the scissor type hydraulic lifter 2. The scissor type hydraulic lifter 2 is used as the existing driving lifting equipment, and the scissor type hydraulic lifter 2 can be controlled to vertically extend and retract, so that the manned platform 3 can be used for ascending a height.
Please refer to fig. 2, wherein two area extension structures 4 are movably connected to two sides of the manned platform 3; each area extension structure 4 comprises an extension table 41 and a hydraulic rod 42 movably connected between the extension table 41 and the lower surface of the manned platform 3.
Specifically, the hydraulic rod 42 at the position where the manned platform 3 needs to move is controlled to extend, and then the piston of the hydraulic rod 42 rotates and jacks up the extension table 41, so that circular motion is performed based on a pin shaft between the extension table 41 and the manned platform 3 as a circle center, and when the extension table 41 is parallel to the manned platform 3, the hydraulic rod 42 stops acting; on the contrary, when the extension table 41 is not used, the extension table 41 can be positioned at the vertical position of the manned platform 3 by the stretching operation of the hydraulic rod 42 on the extension table 41, so that the position of the extension table 41 does not occupy the structural area of the lifting device.
The extension table 41 is made of steel. The steel extension table 41 can have high compressive strength, so as to provide safety for the maintenance personnel.
Two ends of the hydraulic rod 42 are rotatably connected with the extension table 41 and the manned platform 3 through pin shafts; the extension table 41 is rotatably connected with the manned platform 3 through a pin shaft.
