s3: the connecting rod (5) is driven to slide in the corresponding sleeve (6) in the process of pulling a rope or compressing by the oblique spring (28), so that the hand wheel (15) is synchronously driven to rotate by the reset spring, the worm (14) is controlled to rotate by holding the hand wheel (15), the worm (14) drives the worm wheel (29) to rotate at a slow speed, the worm wheel (29) drives the screw rod (32) to rotate, the screw rod (32) is matched with the threads of the two sliding plates (30) and moves towards one side away from each other under the guiding action of the guide plate (33), the two sliding plates (30) drive the two rollers (31) to move towards one side away from each other, the two rollers (31) respectively push the transverse plate (18) to move downwards and compress the supporting spring (34) by abutting against the inner wall of one side of the trapezoidal groove (19), the transverse plate (18) drives the four circular shafts (20) to move downwards, the four circular shafts (20) drive the four arc-shaped plates (21) to move downwards, and the four arc-shaped plates (21) are in close contact with the outer sides of the corresponding walking wheels (13) to limit the rolling of the walking wheels (13), so that the equipment is prevented from moving, and the stability under emergency is ensured;

s4: after the equipment moves to a designated position, the worm (14) is controlled to rotate to the maximum position by holding the hand wheel (15) by hand, then the upper suspension loop of the vertical rod is suspended on the rotating handle of the hand wheel (15) to be locked, the worm (14) drives the worm wheel (29) to rotate slowly in the rotating process of the hand wheel (15), the worm wheel (29) drives the screw rod (32) to rotate, the screw rod (32) is matched with the threads of the two sliding plates (30) and moves to one side far away from each other under the guiding action of the guide plate (33), the two sliding plates (30) drive the two rollers (31) to move to one side far away from each other, the two rollers (31) respectively push the transverse plate (18) to move downwards and compress the supporting spring (34) through abutting connection with the inner wall on one side of the trapezoidal groove (19), the transverse plate (18) drives the four circular shafts (20) to move downwards, and the four circular shafts (20) drive the four arc-shaped plates (21) to move downwards, through the close contact of four arcs (21) and the corresponding walking wheel (13) outside, carry out rolling restriction to walking wheel (13) to prevent that equipment from removing.
