The third air outlet pipes 247 are communicated with a plurality of nozzles 248, and the nozzles 248 incline towards the direction of the suction cup 213 so as to conveniently blow the part of the metal sheet close to the position of the suction cup 213.

When the metal plate needs to be flapped, the first switch valve 245 is closed, the second switch valve 246 is opened, the wind in the fan 212 directly enters the box 241, the plurality of fan blades 232 are driven to rotate, the driving shaft 231 is driven to rotate, and therefore the metal plate can be flapped. At this time, the air inside the case 241 is discharged into the third air outlet pipe 247 through the first air outlet pipe 243, and then is discharged through the nozzle 248. When the metal plate does not need to be flapped, the first switch valve 245 is opened, the second switch valve 246 is closed, and the air inside the box body 241 is discharged into the third air outlet pipe 247 through the second air outlet pipe 244 and then is sprayed out through the spray head 248.

Referring to fig. 1, the lifting mechanism includes a main lifting assembly 12 and an auxiliary lifting assembly 13, the support frame 211 is driven to lift by the main lifting assembly 12, and the support frame 211 is driven to lift by the auxiliary lifting assembly 13, so that the bearing capacity of the main lifting assembly 12 can be reduced, and the support frame 211 can be lifted stably.

Referring to fig. 6, the main lifting assembly 12 includes a first bevel gear 122, the first bevel gear 122 is rotatably disposed on the support rod 11, and the first screw 121 is threaded through a central shaft 133 of the first bevel gear 122.

Referring to fig. 6 and 7, the auxiliary lift assembly 13 includes a second bevel gear 131, a third bevel gear 132, two drive wheels 134, and two drive ropes 135. The second bevel gear 131 and the third bevel gear 132 are respectively located at two sides of the first bevel gear 122, and both the second bevel gear 131 and the third bevel gear 132 are meshed with the first bevel gear 122. The one side that second bevel gear 131 and third bevel gear 132 deviate from mutually all is fixed with center pin 133, and two center pins 133 extend towards the direction that deviates from mutually, and two drive wheels 134 are fixed the cover respectively and are located two center pins 133 on, and the one end of two driving ropes 135 is fixed in respectively on two drive wheels 134, and the other end of two driving ropes 135 all is fixed in on support frame 211. The central shaft 133 of the second bevel gear 131 is connected with a first motor 136, the first motor 136 drives the two driving wheels 134 to rotate, and the first bevel gear 122, the second bevel gear 131 and the third bevel gear 132 to rotate, so that the supporting frame 211 can be driven to ascend through the first screw 121 and the two driving ropes 135. Two driving ropes 135 are in the state of tightening all the time in whole working process, and when first bevel gear 122 rotated, two driving ropes 135 can play the effect of spline to support frame 211, make support frame 211 can only realize elevating movement.

In this embodiment, the first switching valve 245, the second switching valve 246, and the third switching valve 2126 are provided as solenoid valves.

The implementation principle of the anti-falling hoisting equipment for processing the metal plates is as follows: when the metal plate is lifted and conveyed, the first motor 136 controls the support frame 211 to descend, and the suction cup 213 is brought into contact with the metal plate. Next, the third switch valve 2126 is closed, the first switch valve 245 and the second switch valve 246 are opened, the third motor 2145 drives the plurality of working vanes 2122 to rotate, and negative pressure is generated in the first air pipe 2123, so that the suction cup 213 and the metal plate can be reliably attracted. Meanwhile, air is sucked into the housing 2121 through the first air pipe 2123, and the air in the housing 2121 enters the box 241 through the air inlet pipe 242, so as to drive the plurality of fan blades 232 to rotate and drive the driving shaft 231 to rotate, and thus the metal plate can be flapped through the patting block 225. When the suction cup 213 is reliably attached to the metal plate, the third motor 2145 continuously operates, and the air enters the housing 2121 through the fourth air pipe 2127 and enters the box 241 through the air inlet pipe 242, so as to drive the plurality of blades 232 to rotate. When the adhered metal plates are disconnected, the second switching valve 246 is closed and the tapping lever 225 stops sliding. The first motor 136 is started, so that the support frame 211 can be lifted. Finally, the second motor 153 is started to drive the support bracket 211 to move horizontally, so as to place the metal plate at the required position.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
