the method comprises the following steps: when the first servo motor (6) works, the first speed reducer (5) adjusts the speed to drive the transmission shaft (7) to rotate on the shaft seat (9), and then drives the chain wheel (8) to drive the chain to transmit, and at the moment, the lifting tray (2) is driven to lift on one side of the frame (1);
step two: in the lifting process of the lifting tray (2), the hydraulic rod (23) is in a contraction state, at the moment, the first piston (24) moves in the hydraulic box (22), hydraulic oil in the inner cavity (25) of the first sliding block (18) is sucked into the hydraulic box (22), the two second pistons (27) compress the spring (26), the limiting rod (29) is located in the jack (28), and at the moment, the first sliding block (18) and the second sliding block (19) move in the sliding groove (17) along with the lifting of the lifting tray (2);
step three: when the lifting tray (2) is lifted above the steel seat (15), the second servo motor (11) of the anti-falling mechanism (3) works at the moment, the second speed reducer (10) regulates the speed to drive the rotating seat (12) to rotate 90 degrees, and the connecting rotating rod (13) drives the inserting rod (14) to be screwed into the limiting groove (16) of the steel seat (15) to play a limiting role;
step four: when an accident occurs in the lifting process, the hydraulic rod (23) stops working at the moment, the spring (26) restores to the original state to drive the second piston (27) to move towards two sides in the inner cavity (25) of the first sliding block (18) respectively, the limiting rod (29) penetrates through the jack (28) until the limiting rod is connected with the limiting hole (21) in an inserting mode to complete limiting and fixing of the first sliding block (18) and the second sliding block (19), meanwhile, the third servo motor (30) installed on the second sliding block (19) works to drive the rope wheel (32) in the built-in groove (31) to rotate, and the steel rope (33) is always guaranteed to be in a tight state.
