10. An elevator safety gear using method based on elevator safety protection is characterized by comprising the following specific using steps:
the method comprises the following steps: when the lift car (2) goes down due to a problem, the speed limiter brakes the steel wire rope (6), the steel wire rope (6) pulls the second connecting rod (55) to ascend relative to the main shaft (51), so that the second connecting rod (55) drives the main shaft (51) to rotate through the first connecting rod (54) and the first lantern ring (52), the main shaft (51) rotates, the first lantern rings (52) at the two ends of the outer wall of the main shaft (51) synchronously rotate, the two second connecting rods (55) do circumferential overturning motion, the main shaft (51) drives the reset plate (72) to rotate through the second lantern ring (71), the reset plate (72) slides along the circular arc rod (73) to extrude the second spring (76), the two second connecting rods (55) synchronously drive the two first pin shafts (39) to move upwards relative to the clamp (3), and the first pin shafts (39) slide in the second sliding holes (56) at one side of the second connecting rods (55), the first pin shaft (39) drives the first connecting block (38) to slide upwards relative to the third connecting plate (324), so that the first connecting block (38) drives the connecting screw rod (37) to move upwards;
step two: the connecting screw rod (37) drives the second connecting plate (36) to slide upwards relative to the U-shaped frame (33), the second connecting plate (36) drives the two brake blocks (35) to move upwards in an inclined mode relative to the two first connecting plates (34) through the second pin shaft (312) until the two brake blocks (35) are clamped on the outer wall of the sliding rail (4), and therefore the two pliers (3) synchronously clamp the sliding rail (4) to brake the car (2);
step three: when the problem of the elevator is solved, the lift car (2) rises, the speed limiter releases the steel wire rope (6), under the action of the second spring (76), the reset plate (72) restores the original position along the track of the arc rod (73), so that the reset plate (72) drives the main shaft (51) to restore rotation through the second lantern ring (71), the first connecting rod (54) and the second connecting rod (55) drive the first pin shaft (39) and the first connecting block (38) to downwards slide relative to the third connecting plate (324), the first connecting block (38) drives the connecting screw rod (37) to descend, the second connecting plate (36) drives the two brake blocks (35) to downwards slide relative to the first connecting plate (34) through the second pin shaft (312) and is separated from the sliding rail (4), and meanwhile, under the downward action of the first spring (316) on the second connecting plate (36), the second connecting plate (36) can drive the brake blocks (35) to downwards incline, and then the braking of the clamp (3) on the car (2) is released.
