A method for using a safety support device for high-altitude power maintenance work, the method being implemented by using the safety support device for high-altitude power maintenance work according to any one of claims 1 to 9, characterized in that: The following steps are involved: The first step is to firstly use the limiting mechanism (2) provided in the middle of the supporting device body (1) to mount the supporting device body (1) on the high-altitude cable, and to embed the mounting plate (12) at the upper end of the bottom plate (4) in the mounting groove (11) provided at the lower end of the supporting device body (1) through bolts, so that the bottom plate (4) is installed at the lower end of the supporting device body (1), and to embed the mounting plate (12) at the lower end of the top plate (6) in the mounting groove (11) provided at the upper end of the limiting mechanism (2) through bolts, so that the top plate (6) is installed at the upper end of the supporting device body (1) to place the high-altitude operation maintenance tools; In the second step, the drive motor (18) provided on the bottom plate (4) is rotated through the first knob (21) or the second knob (28), so that the drive motor (18) provided on the bottom plate (4) drives the screw rod (24) in the slide groove (23) to rotate, so that the drive motor (18) provided on the screw rod (24) is connected to the transmission member (17) on the rear side of the support device body (1); In the third step, the driving motor (18) drives the double-track pulley (16) through the transmission member (17), so that the double-track pulley (16) controls the two sets of single-track pulleys (14) to move relative to each other in the guide groove (13) through the transmission belt (15), and the aerial cable is clamped between the pressure wheel (30) and the main wheel (31), until the two sets of pressure wheels (30) and the main wheel (31) clamp the aerial cable, so that the supporting device body (1) can be stably and firmly set on the aerial cable; In the fourth step, the support device body (1) can also be arranged on a single or double aerial cables. When the support device body (1) is arranged on a single cable, it only needs to be connected to the single support device body (1) and the bottom plate (4). When the support device body (1) is arranged on a double cable, it only needs to be arranged by arranging a connecting piece (5) in a connecting block (19) arranged on the bottom plate (4), so that the two groups of support device bodies (1) and the bottom plate (4) are symmetrically arranged through the connecting piece (5), and the convex pieces (20) and the concave pieces (22) arranged crosswise at the connecting ends of the two groups of bottom plates (4) are embedded and clamped, and the first knob (21) and the second knob (28) are embedded; In the fifth step, finally, the anti-fall mechanism (3) is provided at the lower end of the bottom plate (4) and the lifting ring (9) is provided on the side of the connecting bracket (8), so that the high-altitude safety protection device can be hung, and a rope can be installed on the lifting ring (9) so that it can follow the operator to move on the high-altitude cable, thereby realizing a more convenient operation of high-altitude power maintenance.
