[0021] By adopting the above technical solution, the user controls the lifting cylinder group 36 to control the lifting fork arm assembly to move up and down on the gantry group 3 to the specified height of the material, and then further controls the coil placement rack 30 to horizontally move the material to the lifting rack 23. In this process, the gear commutator 22 is mainly driven by the hydraulic motor 21, and the shaft 272 is further driven to drive the sprocket 271 to rotate, and the sprocket 271 drives the chain 27 to rotate and move between the inner and outer fork arms 24. At this time, the placement rack 30 fixed with the chain 27 and the pulling group 32 distributed on the placement rack 30 are displaced to the left, and the pulling group 32 horizontally moves the material to the inner and outer fork arms 24.

[0022] Specifically, if Figure 5 and Figure 6 As shown, three groups of support plates 31 are vertically fixed to the upper end surface of the placement rack 30 near the rear stop rod 34, and a transmission shaft 325 passes through and is rotatably connected between the three support plates 31, wherein a gear 326 is fixed on the outside of the transmission shaft 325 between two of the support plates 31, and a pulling group 32 is rotatably connected between the other two support plates 31, a mold thin cylinder 33 is fixed to the rear side of the support plate 31 at the corresponding position of the gear, and a tooth plate 324 is fixed to the output shaft of the mold thin cylinder 33, and the tooth plate 324 is meshingly connected with the gear 1 326.

[0023] Specifically, the material pulling group 32 includes a square tube 1 322, a square tube 2 323 and a hook 321, wherein one end of the square tube 2 323 is movably connected inside the square tube 1 322, the hook 321 is vertically fixed to one end of the square tube 2 323, one end of the square tube 2 323 located in the square tube 1 322 is fixedly connected with a rack 328, the transmission shaft 325 passes through one end of the square tube 1 322, and the connection between the square tube 1 322 and the transmission shaft 325 is embedded with an electromagnet 2 3221 with a ring structure. The second electromagnet 3221 is fixed to the square tube 1 322, and the second electromagnet 3221 is sleeved on the outside of the transmission shaft 325. The inside of the support plate 31 is embedded with an electromagnet 1 329 at the contact position with the square tube 1 322. The outside of the transmission shaft 325 located inside the square tube 1 322 is sleeved with a gear 2 327, and the inner wall of the gear 2 327 is embedded with an electromagnet 3 3271, and the electromagnet 3 3271 is fixed to the gear 2 327 and sleeved on the outside of the transmission shaft 325, and the gear 2 327 is meshingly connected with the rack 328.

[0024] Working principle: When working, the user holds the arm guard group 10, controls the handle assembly 12 and the pedal assembly 7 respectively, and uses the front wheel frame group 1 and the balance wheel group 5 to drive the device as a whole to move and turn under the action of the driving assembly 4. Then the user controls the lifting cylinder group 36 to control the lifting fork arm assembly to move upward to the specified height of the material after the door frame group 3 moves to the material, and then further controls the coil placement rack 30 to move to the right on the lifting fork arm assembly, so that the coil placement rack 30 is close to the material. The material targeted by this application is annular material. In this process, the gear commutator 22 is driven mainly by the hydraulic motor 21, and the shaft 272 is further driven to drive the sprocket 271 to rotate, and the sprocket 271 drives the chain 27 to rotate between the inner and outer fork arms 24. The user then controls the material pulling group 32 to move to the right, and then the user controls the material pulling group 32 to move. At this time, the user further controls the square tube 1 322 and the square tube 2 323 in the material pulling group 32 to deflect clockwise between the support plate 31. The user controls and drives the mold thin oil cylinder 33 to move, and the output shaft of the mold thin oil cylinder 33 drives the tooth plate 324 to move downward. At this time, the gear 1 326 meshing with the tooth plate 324 rotates, and the transmission shaft 325 fixedly connected to the gear 1 326 rotates further. At this time, it is sleeved on the outside of the transmission shaft 325 and runs electrically through the electromagnet 2 3221, so that the transmission shaft 325 and the square tube 1 322 are magnetically attracted to each other, thereby making the square tube 1 322, the direction tube 2 is flipped and parallel to the inner and outer fork arms 24. At this time, the communication displacement of one end of the square tube 2 323 is to the center of the circular material, and then the user controls the electromagnet 2 3221 to cut off the electromagnetic force, and the electromagnet 1 329 conducts electricity to magnetically fix the square tube 1 322 and the support plate 31 to maintain the deflection angle of the square tube. At this time, the user controls the electromagnet 3 3271 to conduct electricity. At this time, the gear 2 327 outside the transmission shaft 325 in the square tube 1 322 is magnetically fixed to the transmission shaft 325, and then the transmission shaft 325 continues to rotate, and the gear 2 327 and the rack 328 meshing with the gear 2 327 drive the displacement, and the square tube 1 322 connected to the rack 328 is displaced inside the square tube 2 323, and the position of the square tube 1 322 The hook head 321 is moved to move, so that the hook head 321 is in close contact with the inner wall of the center hole of the circular material, thereby realizing the contact of the hook head 321 with the circular material that does not pass through the large and small diameters, without the need to manually adjust the length of the square tube 1 322 and the square tube 2 323. When the hook head 321 contacts the circular material, the user further controls the hydraulic motor 21 to run in the reverse direction, and further turns the driving shaft 272 to drive the sprocket 271 and the chain 27, thereby driving the placement rack 30 to move in the reverse direction. At this time, the hook head 321 hooks the material and pulls the material to the surface of the driven wheel group 26 on the inner and outer fork arms 24. The driven wheel group 26 rotates to reduce the sliding resistance of the material on the surface of the inner and outer fork arms 24 until the material is completely displaced to the driven wheel group 26.Completely displaced to the inner and outer fork arms 24; Then the user controls the lifting cylinder group 36 to move in the reverse direction, and moves the lifting fork arm assembly and the material on the lifting fork arm assembly downward, until the inner and outer fork arms 24 in the lifting fork arm assembly are displaced between the two gate seat groups 2, that is, the lower end surface of the material is in contact with the upper end surface of the rotating arm 16; Then the user controls the oil cylinder flipping mechanism to flip the materials horizontally distributed on the inner and outer fork arms 24 on the lifting fork arm assembly by 90 degrees, and vertically distribute the materials on the placement rack 30; At this time, the user controls the cylinder body 15 to retract, and the cylinder body 15 further pulls the rotating arm 16. At this time, the rotating arm 16 is folded ninety degrees on the rotating support 17. During the flipping process, the rotating arm 16 flips and moves the material on the upper side together, and flips the material vertically on the placement rack 30, thereby realizing complete height adjustment for material collection, horizontal material flipping, and subsequent transportation or stacking operations.
