b: test adjustment, namely driving a winding column (25) to rotate clockwise or anticlockwise through a second motor (23), winding a pull rope (28), adjusting the horizontal height of a pendulum bob (29), controlling the swinging range of the pendulum bob (29), driving a lifting plate (15) to move up and down through a first motor (21), adjusting the horizontal height of the lifting plate (15), and enabling the pendulum bob (29) to correspond to different positions of an elevator landing door test mechanism;
c: the driving test is carried out, after the pendulum bob (29) is confirmed to impact the pendulum bob (29) on the local part of the elevator landing door test mechanism, the driving plate (10) is driven by the gear (13) to move back and forth in the movable groove (11), the pendulum bob (29) is swung up, the local part of the elevator landing door test mechanism is impacted by the pendulum bob (29), the impact degree of the pendulum bob (29) on the elevator landing door test mechanism is observed and recorded, and the impact tests are carried out on a plurality of local parts of the elevator landing door test mechanism and recorded;
d: after a plurality of local impact tests of the pendulum bob (29) on the elevator landing door test mechanism, the pull rope (28) is wound into the winding column (25) through the second motor (23), the horizontal height of the pendulum bob (29) is lifted, the swing range is reduced, meanwhile, the pressing plate (35) is pressed down through the rotation of the threaded rotating handle (33), and the pull rope (28) is prevented from slipping through the first anti-slip tooth (36) and the second anti-slip tooth (38).
