[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] Example 1 Reference Figure 1-9As shown: a multi-purpose safety lifting frame for substation construction, including a support frame 1, a crossbeam 2, and a lifting assembly 3. The upper end of the crossbeam 2 is fixedly installed with a mounting top plate 4, and one end of the mounting top plate 4 is fixedly installed with a driving motor 41. The output end of the driving motor 41 is transmission-connected with a screw rod 42, and the outer side of the screw rod 42 is threadedly connected to a driving block 43. One side of the driving block 43 is fixedly connected with a transmission frame 44, and one end of the transmission frame 44 is fixedly connected to the top surface of the lifting assembly 3. A safety belt fixing assembly 5 is provided on one side of the mounting top plate 4. The lifting assembly 3 is movably connected to the outer side of the crossbeam 2.

The elevator 31 drives the lifting platform 6 to move upward to the specified height to complete the transportation task. During the transportation process, the four limit rods 454 will constrain the movement direction of the lifting platform 6 so that the lifting platform 6 can rise vertically. When the horizontal position of the lifting platform 6 and the lifting assembly 3 needs to be adjusted, the drive motor 41 is started, driving the screw rod 42 to rotate, and the screw rod 42 drives the drive block 43 to move. Since the drive block 43 is fixedly connected to the transmission frame 44 and the adjusting ring 453, the drive block 43 can drive the lifting platform 6 and the lifting assembly 3 to move horizontally. When the lifting platform 6 moves horizontally, the lifting platform 6 drives the slider 72 to slide on the slide rail 71, thereby constraining the movement direction of the lifting platform 6 in the horizontal direction.
