[0034] The oil cylinder flipping mechanism includes an oil cylinder support 14, an oil cylinder body 15, a rotating arm 16, a rotating support 17, and a limit block 18. The oil cylinder support 14 is fixed to the mast group 3, and the oil cylinder body 15 is hinged to the oil cylinder support 14. The output end of the oil cylinder body 15 is hinged to the rotating arm 16. A rotating support 17 is provided at the bottom of the rotating arm 16, and the rotating arm 16 is rotatably connected to the rotating support 17. The lower end of the rotating support 17 is fixed to the gantry group 2. A limit block 18 is vertically and fixedly connected to the lower end surface of the rotating arm 16 near the front wheel frame group 1. During operation, the user holds the protective arm groups 10 and respectively controls the handle assembly 12 and the pedal assembly 7. Under the action of the drive assembly 4, the device is driven to move and turn as a whole by using the front wheel frame group 1 and the balance wheel group 5. Then, the user controls the lifting oil cylinder group 36 to control the lifting fork arm assembly to move upward on the mast group 3 to the specified height of the material.

[0035] Specifically, as Figure 2 With Figure 3 And Figure 4As shown in the figure, a lifting fork arm assembly is provided on the right side of the gantry group 3, and the lifting fork arm assembly is located above the oil cylinder flipping mechanism. A lifting oil cylinder group 36 is provided between the lifting fork arm assembly, the gantry group 3 and the gantry seat group 2. The lifting oil cylinder group 36 consists of a chain 27 sheave, a support shaft, a cylinder barrel, a piston rod and an oil cylinder seat fitting. The lifting fork arm assembly is driven by the lifting oil cylinder group 36 to move up and down on the right side of the gantry group 3. The lifting fork arm assembly includes inner and outer fork arms 24 with an L-shaped structure design. One end of the inner and outer fork arms 24 close to the gantry group 3 is fixedly connected with a lifting frame 23. On the side of the lifting frame 23 far from the inner and outer fork arms 24, roller frames 20 are symmetrically fixed. A sheave group 19 is rotatably connected to the roller frames 20. The sheave group 19 is located inside the gantry group 3 and rolls in contact with the inner wall of the gantry group 3. On the front and rear symmetry of the upper end face of the inner and outer fork arms 24, a driven wheel group 26 is distributed. The driven wheel group 26 is rotatably connected to the inner and outer fork arms 24. An activity groove is reserved between the two driven wheel groups 26, and a chain 27 is movably connected in the activity groove. On the side of the inner and outer fork arms 24 close to the lifting frame 23, a rear support plate 25 is horizontally fixedly connected. A hydraulic motor 21 is installed on the rear support plate 25. A gear commutator 22 is installed on the lower side of the rear support plate 25. The output shaft of the hydraulic motor 21 is in transmission connection with the gear commutator 22;

[0036] A shaft rod 272 is rotatably connected to the inner part of the inner and outer fork arms 24 at a position corresponding to the gear commutator 22, and one end of the shaft rod 272 is in transmission connection with the gear commutator 22. A sprocket 271 is fixedly sleeved on the outer part of the shaft rod 272 at a position corresponding to the chain 27. The chain 27 is sleeved on the sprocket 271. A front support plate 29 is fixedly connected to the right end of the inner and outer fork arms 24. A sprocket 271 is also rotatably connected in the front support plate 29 and meshes with the chain 27. A coil placing mechanism is arranged on the inner and outer fork arms 24. The coil placing mechanism includes a placing frame 30 fixed on the upper end face of the inner and outer fork arms 24. On the left side of the upper end face of the placing frame 30, rear stop rods 34 are symmetrically arranged. The rear stop rods 34 are vertically fixedly connected to the placing frame 30. The bottom of the placing frame 30 is fixed to the chain 27. Guide wheels 35 are symmetrically rotatably connected to the bottom of the placing frame 30, and the guide wheels 35 roll in contact with the upper end face of the lower inner and outer fork arms 24.

[0037] By adopting the above technical solution, the user controls the lifting oil 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 coiling material placement rack 30 to horizontally displace the material onto the lifting rack 23. During this process, it is mainly driven by the hydraulic motor 21 to drive the gear commutator 22, which further drives the shaft rod 272 to drive the sprocket 271 to rotate. The sprocket 271 drives the chain 27 to rotate and displace between the inner and outer fork arms 24. At this time, the placement rack 30 fixed to the chain 27 and the material pulling group 32 distributed on the placement rack 30 move to the left, and the material pulling group 32 horizontally displaces the material onto the inner and outer fork arms 24.

[0038] Specifically, as Figure 5 shown in Figure 6 , three support plates 31 are vertically fixed at the position of the upper end surface of the placement rack 30 close to the rear material stop rod 34. A transmission shaft 325 is penetrated and rotatably connected between the three support plates 31. A first gear 326 is sleeved and fixed outside the transmission shaft 325 between two of the support plates 31. A material pulling group 32 is rotatably connected between the other two support plates 31. A die thin cylinder 33 is fixed at the position corresponding to the gear on the rear side of the support plate 31, and a toothed plate 324 is fixed to the output shaft of the die thin cylinder 33. The toothed plate 324 is meshed and connected with the first gear 326.

[0039] Specifically, the material pulling group 32 includes a square tube one 322, a square tube two 323 and a hook 321. One end of the square tube two 323 is movably connected inside the square tube one 322. The hook 321 is vertically fixed to one end of the square tube two 323. A rack 328 is fixed to one end of the square tube two 323 located inside the square tube one 322. The transmission shaft 325 penetrates one end of the square tube one 322, and an annular electromagnet two 3221 is embedded at the connection position between the square tube one 322 and the transmission shaft 325. The electromagnet two 3221 is fixed to the square tube one 322. The electromagnet two 3221 is sleeved outside the transmission shaft 325. An electromagnet one 329 is embedded at the position where the support plate 31 contacts the square tube one 322 inside. A second gear 327 is sleeved outside the transmission shaft 325 located inside the square tube one 322. An electromagnet three 3271 is embedded in the inner wall of the second gear 327. The electromagnet three 3271 is fixed to the second gear 327 and sleeved outside the transmission shaft 325. The second gear 327 is meshed and connected with the rack 328.

[0040] Working principle: During operation, the user holds the arm guard group 10 by hand and, respectively, through the control handle assembly 12 and the pedal assembly 7, under the action of the drive assembly 4, uses the front wheel frame group 1 and the balance wheel group 5 to drive the entire device for displacement and steering. Then, the user controls the lifting oil cylinder group 36 to control the lifting fork arm assembly to move upward on the gantry group 3 to the specified height of the material. Then, the user further controls the coiling placement rack 30 to move to the right on the lifting fork arm assembly, making the coiling placement rack 30 close to the material. The material targeted by this application is ring-shaped material. During this process, it is mainly driven by the hydraulic motor 21 to drive the gear commutator 22, which further drives the shaft rod 272 to drive the sprocket 271 to rotate. The sprocket 271 drives the chain 27 to rotate and displace between the inner and outer fork arms 24. At this time, the placement rack 30 fixed to the chain 27 and the material pulling group 32 distributed on the placement rack 30 move to the right. Then, the user controls the operation of the material pulling group 32. At this time, the user further controls the square tube one 322 and the square tube two 323 in the material pulling group 32 to deflect clockwise between the support plates 31. The user controls and drives the die thin oil cylinder 33 to operate. The output shaft of the die thin oil cylinder 33 drives the toothed plate 324 to move downward. At this time, the gear one 326 meshing with the toothed plate 324 rotates, and the transmission shaft 325 fixedly connected to the gear one 326 further rotates. At this time, it is sleeved outside the transmission shaft 325 and conducts electricity through the electromagnet two 3221 to form a magnetic attraction structure between the transmission shaft 325 and the square tube one 322, thereby causing the square tube one 322 and the direction tube two to flip and be parallel to the inner and outer fork arms 24. At this time, the communication at one end of the square tube two 323 is displaced to the center of the ring-shaped material. Then, the user controls the electromagnet two 3221 to cut off the electromagnetic force and the electromagnetic force disappears. The electromagnet one 329 conducts electricity to magnetically fix the square tube one 322 and the support plate 31, maintaining the deflection angle of the square tube. At this time, the user controls the electromagnet three 3271 to conduct electricity. At this time, the gear two 327 outside the transmission shaft 325 in the square tube one 322 is magnetically fixed to the transmission shaft 325. Then, the transmission shaft 325 continues to rotate, and in cooperation with the gear two 327 and the rack 328 meshing with the gear two 327, it drives displacement. The square tube one 322 connected to the rack 328 displaces inside the square tube two 323. The displacement of the square tube one 322 drives the hook 321 to displace, making the hook 321 fit and contact the inner wall of the central hole of the ring-shaped material, thereby realizing the contact of the hook 321 for ring-shaped materials with different diameters without the need for manual adjustment of the common length of the square tube one 322 and the square tube two 323. When the hook 321 contacts the ring-shaped material, at this time, the user further controls the hydraulic motor 21 to run in the reverse direction and further flips through the drive shaft rod 272, driving the sprocket 271 and the chain 27, and then driving the placement rack 30 to displace in the reverse direction. At this time, the hook 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 itself 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 onto the driven wheel group 26.Completely displaced onto the inner and outer fork arms 24;

[0041] Then the user controls the lifting oil cylinder group 36 to move in the reverse direction, lowering the lifting fork arm assembly and the materials located on the lifting fork arm assembly until the inner and outer fork arms 24 in the lifting fork arm assembly are displaced between the two portal groups 2, that is, the lower end face of the material is in close contact with the upper end face of the rotating arm 16;

[0042] Subsequently, the user controls the oil cylinder flipping mechanism to flip the materials horizontally distributed on the inner and outer fork arms 24 of the lifting fork arm assembly by 90 degrees, vertically distributing the materials on the placement rack 30;

[0043] At this time, the user controls the main body of the oil cylinder 15 to contract, and the main body of the oil cylinder 15 further pulls the rotating arm 16. At this time, the rotating arm 16 flips by 90 degrees on the rotating support 17. During the flipping process, the rotating arm 16 also flips and moves the materials on the upper side, vertically flipping the materials on the placement rack 30, thereby realizing complete height-adjustable material picking, horizontal material flipping, and then subsequent transportation or stacking operations.

[0044] The main features of the oil cylinder flipping mechanism of a coil flipping, loading, transporting, and stacking truck involved in this patent are as follows: The maximum load-bearing capacity is 1T, the maximum lifting height is 1.5m, the body width is 0.8m, the total length is 2.3m, the height is 2m, and the effective length of the fork arms is 0.7m. It can directly pull the flat coils from the rack onto the vehicle, then use the two sets of rotating mechanisms equipped on the vehicle to stand up the coils, and then push them onto the material rack. This greatly reduces the labor intensity of employees, reduces site restrictions, improves work efficiency, and reduces operation risks.

[0045] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
