The first magnetic head (17) and the second magnetic head (19) are L-shaped structures, and the inner sides of the first magnetic head (17) and the second magnetic head (19) fit each other.

6. A detection method based on the garbage bin grab wire rope damage detection device according to any one of claims 1 to 5, characterized in that: The following steps are involved: Step 1: Start the winch (3) to release the rope, pass the rope through the bottom of the bearing base (1) and out from the top of the guide bracket (7), and then fix the rope of the winch (3) to the bracket part of the garbage bin grab; Step 2: remotely start the motor (20) to drive the adjusting rack (5) to move inward through the driving gear (22), and simultaneously drive the multiple adjusting racks (5) to move synchronously under the drive of the driving gear ring (23). During the movement, the follower connecting rod (6) is synchronously pushed outward to separate the first clamping bracket (10) from the second clamping bracket (14), and the second detection flap (16) and the third detection flap (18) are unfolded outward by the drive of the retracting and unfolding connecting rod (4), and then the garbage bin grabbing bucket wire rope to be inspected is inserted between the second detection flap (16) and the third detection flap (18), and then the motor (20) is started to retract the second detection flap (16) and the third detection flap (18), and the wire rope is clamped between the first guide wheel (11) and the second guide wheel (13); Step 3: Start the winch (3) through the remote control device, release the rope of the winch (3), lower the equipment by means of a sling, and test the steel wire rope in the area step by step, or keep the winch (3) locked and test by the self-movement of the steel wire rope of the garbage bin grab.
