The implementation principle of the embodiment of the application is as follows: when the traction rope pulls the walking plate to drive the lead to move towards the direction close to the pulley, the upper limiting plate 3 is abutted with the pulley 2, so that the phenomenon of jump of the traction rope is not easy to occur; when the walking board moves to the first mounting plate 4, the roller on the walking board is abutted with the fan blade of the first impeller 101 and pushes the first impeller 101 to rotate, the first impeller 101 drives the first rod body 19 to rotate, the screw 9 is driven to rotate through the transmission of the second belt wheel 1021 and the second belt 1022, and the screw 9 drives the upper limit plate 3 to slide towards the direction far away from the pulley 2, so that a space is reserved for the walking board to pass through the pulley 2; then the walking board moves to the sliding plate 61, the rollers on the walking board and the cambered surface of the sliding plate 61 slide relatively, the sliding plate 61 is pushed to slide towards the direction close to the sliding groove 17, the spring 621 is compressed, the tension of the connecting rope 631 to the rotating shaft 7 is reduced, the torsion spring 632 on the rotating shaft 7 drives the lower limiting plate 5 to rotate towards the direction close to the upper limiting plate 3, the rotating shaft 7 winds the connecting rope 631, the roller 13 on the lower limiting plate 5 is abutted to the bottom wall of the walking board, and therefore the walking board is limited between the upper limiting plate 3 and the lower limiting plate 5, the walking board is not easy to be in an inclined state when passing through the pulley 2, the possibility that the walking board collides with the pulley 2 is reduced, friction is reduced, and the walking board is convenient to pass through the pulley smoothly.
When the roller on the walking board is separated from the sliding plate 61, the spring 621 pushes the sliding plate 61 to move towards the direction away from the sliding groove 17, so that the connecting rope 631 pulls the rotating shaft 7 to drive the lower limiting plate 5 to rotate towards the direction away from the upper limiting plate 3, the lower limiting plate 5 is not easy to influence the wire to pass through the pulley 2, and the next use is convenient.
When the walking board smoothly walks to the second impeller 121 through the pulley, the rollers on the walking board are abutted with the blades of the second impeller 121 and push the second impeller 121 to rotate towards the direction same as the rotation direction of the first impeller 101, the second impeller 121 drives the second rod body 21 to rotate, the first gear 1222 drives the second gear 1223 and the transmission rod 1221 to rotate, the rotation direction of the transmission rod 1221 is opposite to that of the second impeller 121, and the screw 9 is driven to reversely rotate through the transmission of the first pulley 1224 and the first belt 1225, so that the screw 9 drives the upper limiting plate 3 to move towards the direction close to the pulley 2, the groove 8 on the upper limiting plate 3 and the corresponding pulley 2 form a space for a wire to pass, the possibility of a wire to generate a jump groove is reduced, and the practicability is strong.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
