[0039] Furthermore, the transfer mechanism includes a collecting groove 56 located at the upper end of the holding platform 1, a semicircular groove 57 is opened at the lower end of the collecting groove 56, a holding box 58 is placed on the front side of the collecting groove 56, a universal wheel 59 is installed on the lower surface of the holding box 58, the universal wheel 59 is placed in the semicircular groove 57, a fixed handle 60 is installed on one side of the upper end of the holding box 58, a triangular prism 61 is installed on one side surface of the holding platform 1, and a placement box 62 is installed on the rear side of the collecting groove 56 to facilitate the transfer of finished products.

[0040] In this embodiment, the electrical equipment of this device is controlled by an external controller. The iron accessories that need to be galvanized are bundled and placed in a storage box 57. The storage box 57 can be moved from the triangular prism 61 to the collection groove 56 by fixing the handle 60 and the universal wheel 58, and the universal wheel 58 is allowed to enter the semicircular groove 57. The brake pads on the universal wheel 58 are locked to prevent it from moving. The lifting rod 23 is placed in the placement box. Under normal circumstances, the support platform 9 is in a horizontal state, one end of the rotating platform 9 is connected to the take-up wheel 11 by a connecting line 12, and the rotating shaft 6 is connected to the brake motor 51 through the meshing of the first gear 50 and the second gear 52. When the brake motor 51 is not started, it is in a self-locking state, which can prevent the rotating platform 9 from rotating, thereby keeping the support platform 9 in a horizontal state. The wire rope on the vehicle connects the lifting ring 22 on the lifting platform 14, so that the lifting platform 14 can be raised and moved above the placing platform 1, and the lifting platform 14 is slowly lowered by the overhead crane. The guide wheel 55 on the lifting platform 14 first contacts the tilting platform 54, and the rotation of the guide wheel 55 can reduce the friction when the lifting platform 14 moves. Through the guiding effect of the tilting platform 54 and manual assistance, the lifting platform 14 can fall into the placing groove 13. When the lifting platform 14 falls, the limiting wheel 30 first contacts the tilting block 32 and stretches the moving plate 28 toward the outside of the supporting platform 9. The rotation of the limiting wheel 30 can reduce the friction between the limiting wheel 30 and the tilting block 32. When the moving plate 28 moves toward the outside of the supporting platform 9, the second connecting spring 29 can be stretched, and the limiting rod 26 can be pulled into the limiting hole 27.

[0041] The staff starts the brake motor 51 to rotate forward, and the brake motor 51 can drive the second gear 52 to rotate, and through the meshing between the gears, it can drive the first gear 50, the rotating shaft 6, and the take-up wheel 11 to rotate. When the take-up wheel 11 rotates, the connecting line 12 can be retracted, and the connecting line 12 can pull the connecting ring 10 upward and pull up one end of the support platform 9. The other end of the support platform 9 is installed on the rotating rod 7. The two ends of the rotating rod 7 are inserted into the second rolling bearing 8, which can make the support platform 9 rotate around the second rolling bearing 8 and make the rotating wheel 49 on the support platform 9 move in the arc slide 48, which can play a certain guiding and supporting role. After rotating a certain angle, turn off the brake motor 51. The self-locking function of the brake motor 51 can prevent the support platform 9 from reversing. The lifting platform 14 is tilted when the lifting rod 23 is lifted and the lifting plate 36 is used to pull the lifting rod 35 and the lifting plate 36 is used to pull the lifting rod 35 and the lifting plate 36 are ... rod 23 are used to pull the lifting rod 35 and the lifting plate 36 are used to pull the lifting rod 35 and the lifting rod 23 are used to pull the lifting rod 35 and the lifting plate 36 are used to pull the lifting rod 35 and the lifting rod 23 are used to pull the lifting rod 35 and the lifting rod 23 are used to pull the lifting rod 35 and the lifting rod 23 are used to pull the lifting rod 35 and the lifting rod 23 are used to pull the lifting rod 35 and the lifting rod 23 are used to pull the lifting rod 35 and the lifting rod 23 are used to pull the lifting rod 35 and the lifting rod 23 are used to pull the lifting rod 35 and the lifting rod 23 are used to pull the lifting rod 35 and the lifting rod 23 are used to pull the lifting rod 35 The rear side of the loading platform 14 moves. After the pulley 24 passes, the lifting platform 38 is released. Under the action of gravity and the pulling force of the third connecting spring 37, the lifting rod 35 can be pulled into the guide slide 15 from the circular through hole 34 to block the next hanging rod 23. The guide slide 15 can guide the hanging rod 23. The pulley 24 can reduce the friction when the hanging rod 23 moves. When the hanging rod 23 moves to the rear side, the pulley 24 pushes the first rotating plate 21 to the rear side, and the rotating plate 21 rotates around the hinge without blocking the pulley 24. After the pulley 24 passes, under the action of gravity, the rotating plate 24 returns to its original position, and the pulley 24 first contacts the inclined surface 39 on the lifting block 17, and moves the lifting block 17 to the inner and lower sides of the square groove 16. The guide rod 18 and the guide cylinder 19 can ensure the moving direction of the lifting block 17, and the first connecting spring 20 can be compressed. When the lifting block 17 moves downward, the lifting column 42 can be pulled downward from the circular groove 41 through the connection between the L-shaped connecting rod 46 and the first connecting shaft 44 and the second connecting shaft 45, and the rear side of the rotating plate 21 is blocked. At this time, the rotating plate 21 cannot rotate backward, and the rear hanging rod 23 can be blocked to keep a certain gap between the hanging rods 23. When the pulley 24 on the hanging rod 23 falls on the lifting block 17 and continues to move backward, the pulley 24 breaks through the next rotating plate 21 and moves backward. At this time, the lifting block 17 is pushed upward by the elastic force of the first connecting spring 20.The lifting column 42 is pushed into the circular groove 41 through the connection between the L-shaped connecting rod 46 and the first connecting shaft 44 and the second connecting shaft 45. At this time, the rear side of the rotating plate 21 is not blocked and can rotate freely. At this time, the pulley 24 on the first hanging rod 23 breaks through the rotating plates 21 one by one under the action of gravity and slides to the rear side until it is blocked by the block 33. At this time, the lifting block 17 on the rear side is pressed into the square groove 16, and the lifting column 42 on the front side of this lifting block 17 is pulled downward to prevent the rotating plate 21 on the front side from rotating. The pulley 24 falls into the arc groove 41. At this time, the lifting block 17 on the rear side is pressed into the square groove 16, and the lifting column 42 on the front side of the lifting block 17 is pulled downward to prevent the rotating plate 21 on the front side from rotating. The pulley 24 falls into the arc groove 41. The operator puts the second hoisting rod 23 at the front end of the guide slide 15, the pulley 24 on the hoisting rod 23 is blocked by the lifting rod 35, and the iron accessories are hung on the hook at the lower end of the hoisting rod 23. After the hanging is completed, the lifting platform 38 and the lifting rod 35 are pulled upward, which can move the second hoisting rod 23 to the rear side, and make the pulley on this hoisting rod 23 blocked by the rearmost rotating plate 21. By analogy, enough hoisting rods 23 can be placed in the guide slide 15. When the iron accessories are large in size, the iron accessories can be placed on the adjacent hoisting rods 23 to ensure the spacing between the iron accessories.

[0042] After the iron accessories are placed, the brake motor 51 is started to reverse and drive the second gear 52 to rotate. Through the meshing of the second gear 52 and the first gear 50, the first gear 50, the rotating shaft 6, and the take-up wheel 11 can be driven to rotate, and the connecting line 12 can be released. At this time, under the action of gravity, the originally higher end of the support platform 9 rotates downward, and after the support platform 9 returns to a horizontal state, the brake motor 51 is turned off. At this time, the pulley 24 on the lifting rod 23 falls into the arc groove 40, which can prevent the lifting rod 23 from moving. The crane is started to lift the lifting platform 14 through the lifting ring 22. When the lifting platform 14 is raised, under the elastic force of the second connecting spring 29, the movable plate 28 and the limiting wheel 30 can be moved toward the inner side of the support platform 9, and the limiting rod 26 can be moved through the limiting hole 27 to the guide slideway 15, and the pulley 24 is limited. When the lifting platform 14 moves, the lifting rod 23 can be prevented from sliding to one side due to the tilt, and the lifting platform 14 is moved to the galvanizing place for galvanizing.

[0043] After galvanizing is completed, the lifting platform 14 can be positioned by the tilting platform 54 and the L-shaped guide platform 53, and the lifting platform 14 can be lifted back onto the supporting platform 9. At this time, the limit rod 26 is pulled into the limit hole 27 and will not block the pulley 24. The brake motor 51 is started to reverse and drive the second gear 52 to rotate. Through the meshing of the second gear 52 and the first gear 50, the first gear 50, the rotating shaft 6, and the take-up wheel 11 can be driven to rotate, and the connecting line 12 can be released. At this time, under the action of gravity, one end of the supporting platform 9 rotates downward, so that one end of the supporting platform 9 tilts downward, and the lifting platform 14 Tilt, at this time the hoisting rod 23 slides forward, the rotating plate 21 will not block the pulley 24, the pulley 24 on the front hoisting rod 23 is blocked by the lifting rod 35, which can prevent the hoisting rod 23 from sliding down, and the staff will remove the iron accessories on the hook 25 and put them in the storage box 57, remove the hoisting rod 23 and put it in the display box 62, after all the galvanized iron accessories are removed, repeat the above process, and the iron accessories can continue to be galvanized.

[0044] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
