Step S1: the driving gear 43 can be controlled to rotate in the reduction gearbox 41 firstly by starting the rotating motor 42, the driven gear 44 can be engaged to control to rotate in the process of rotating the driving gear 43, the turntable 45 can drive the mounting plate 10 and the lifting cylinder 11 above the turntable 45 to integrally rotate the whole truss 12 in the process of rotating the driven gear 44, so that the truss 12 can be ensured to move from the hopper 13 to the outside of the car body 1, the winding motor 52 is required to be started to drive the exchange gear 53 to control the mounting seat 54 to wind the steel cable 55 during lifting, and the lifting movement of the lifting seat 20 can be realized during winding of the steel cable 55.
Step S2: when the round oil tank or other round products need to be hoisted, the lifting hook 31 is quite unsuitable for a user, at the moment, the user needs to descend the lifting seat 20 to a proper position of the round products, then the four electric cylinders 204 are started to control the four positioning claws 205 to open and close, then the positioning claws 205 are placed on the round products, and then the electric cylinders 204 are controlled to drive the positioning claws 205 to close, so that the round products can be grabbed, and the hoisting of the round products can be easily completed.
Step S3: when the ordinary product needs to be hoisted, a user can start the overturning motor 21 to control the rotating seat 22 to rotate by ninety degrees to enable the direction of the lifting hook 31 to be downward, and then in the hoisting process, the deflector 33 needs to be pressed to enable the baffle 32 to overturn so as to form an opening on the lifting hook 31, so that the ordinary product can be hoisted.
Step S4: when the first locking plate 72 is in the working state of the hoisting mechanism 3, if the swivel seat 22 is controlled to overturn continuously, the first locking rod 19 enters the first engagement groove 75, the first locking plate 72 is controlled to descend on the first limiting rod 73 along with continuous rotation, the first spring 74 is in a compressed state, after the first locking plate 72 descends, the first clamping rod 71 can be guaranteed to be taken out from the swivel seat 22, and the first locking plate 71 is in the working state of the grabbing mechanism 2, if the swivel seat 22 is controlled to overturn continuously, the second locking rod 18 enters the second engagement groove 85, the second locking plate 82 is controlled to descend on the second limiting rod 83 along with continuous rotation, and the second clamping rod 81 can be guaranteed to be taken out from the swivel seat 22 after the second locking plate 82 descends.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the specification and drawings of the present invention or direct/indirect application in other related technical fields are included in the scope of the present invention.
