The present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0037] In one embodiment of the present invention, see Figures 1 to 9 , a conveying device for warehousing logistics, comprising a cart 1, a rotating mounting frame 10, a mobile frame 18, a hoisting assembly 53, an elastic buckle assembly 54, a synchronous drive assembly 55, and a safety lock assembly 56;

[0038] The cart 1 is fixedly connected with a fixed rod 6, and a rotating rod 7 is rotatably connected with the fixed rod 6. A second connecting pin 8 is inserted between the rotating rod 7 and the fixed rod 6. A fixed connecting rod 9 is fixedly connected with the rotating rod 7. One end of the rotating mounting frame 10 is rotatably connected to the fixed connecting rod 9. The top of the rotating rod 7 is rotatably connected with one end of a rotating connecting rod 11. The other end of the rotating connecting rod 11 is rotatably mounted with the rotating mounting frame 10 through a connecting bolt 12.

[0039] The rotating mounting frame 10 is provided with a mounting groove 13, a fixed rack 14 is provided at the bottom of the mounting groove 13, a connecting plate 15 is provided at the top of the rotating mounting frame 10, and lifting racks 16 are fixedly connected on both sides of the connecting plate 15, and limit blocks 17 are fixedly connected on both sides of the lifting rack 16, and the limit blocks 17 are provided in the mounting groove 13;

[0040] The movable frame 18 is arranged at the bottom of the rotating mounting frame 10, and two groups of connecting shafts 19 are rotatably connected at the top of the movable frame 18, and gears 20 are fixedly connected at both ends of the connecting shaft 19, and the gears 20 are arranged between the fixed rack 14 and the lifting rack 16, and the gears 20 are meshed with the fixed rack 14 and the lifting rack 16. The bottom of the movable frame 18 is rotatably connected with a rotating shaft 21, and a first winding disk 22 is fixedly connected at the middle position of the rotating shaft 21, and a second winding disk 23 is fixedly connected at both ends of the rotating shaft 21, and one end of a traction steel cable 33 is fixedly connected to the second winding disk 23, and the other end of the traction steel cable 33 is fixedly connected to a mounting plate 34, and a plurality of groups of equidistantly distributed mounting rings 35 are installed at the bottom of the mounting plate 34, and one end of a driving steel cable 51 is fixedly connected to the first winding disk 22, and the other end of the driving steel cable 51 is connected to the winch assembly 53;

[0041] The mounting groove 13 is fixedly connected with a mounting slide rod 42, and a sliding cylinder 43 is slidably connected to the mounting slide rod 42. The sliding cylinder 43 is fixedly connected to the moving frame 18, and a second spring 44 is provided on the side of the sliding cylinder 43 close to the hoisting assembly 53 and sleeved on the mounting slide rod 42;

[0042] The hoisting assembly 53 is installed on the cart 1; the elastic buckle assembly 54 is installed on both sides of the mobile frame 18; the synchronous drive assembly 55 is installed between the elastic buckle assembly 54 and the mounting plate 34; the safety lock assembly 56 is installed between the synchronous drive assembly 55 and the second winding drum 23;

[0043] When the present invention is not in use, the rotating rod 7 can be first rotated and raised, and the second connecting pin 8 can be inserted between the fixed rod 6 and the rotating rod 7, so that the fixed rod 6 and the rotating rod 7 are relatively fixed. At this time, the cart 1 can be used to place and transport lighter goods. When it is necessary to transport heavier goods, the rotating mounting frame 10 can be rotated, and the rotating connecting rod 11 and the rotating mounting frame 10 can be fixed and installed by the connecting bolts 12. At this time, a triangular support is formed between the rotating rod 7, the rotating connecting rod 11 and the rotating mounting frame 10, thereby achieving stable installation and fixation between the rotating rod 7 and the rotating mounting frame 10. At this time, the rotating mounting frame 10 is rotated and unfolded, and the goods can be tied and fixed by one end of the lifting rope, and then the other end of the lifting rope is installed on the installation ring 35, thereby completing the preliminary lifting of the goods;

[0044] After that, the driving steel cable 51 can be driven by the winch assembly 53 to be wound. At this time, the connecting plate 15 is first limited and clamped by the elastic buckle assembly 54. At this time, the connecting plate 15 drives the lifting rack 16 to be pressed down, and then the fixed rack 14 and the lifting rack 16 are meshed with the gear 20 to achieve the clamping and fixing of the gear 20, thereby limiting the horizontal movement of the gear 20, that is, the rotating mounting frame 10 and the moving frame 18 are relatively fixed. At this time, the steel cable of the winch assembly 53 drives the first winding drum 22 to rotate, and the first winding drum 22 drives the two sets of second winding drums 23 to rotate through the rotating shaft 21, and the second winding drum 23 drives the traction steel cable 33 to be wound, and then the traction steel cable 33 drives the mounting plate 34 to be lifted, and the mounting plate 34 is installed The lifting ring 35 drives the goods to rise, and then when the mounting plate 34 rises to the top, the mounting plate 34 contacts the synchronous drive assembly 55, and at this time the synchronous drive assembly 55 drives the safety lock assembly 56 to close, thereby axially limiting and locking the second winding drum 23 through the safety lock assembly 56, so as to prevent the goods from accidentally falling, and at the same time the synchronous drive assembly 55 drives the elastic buckle assembly 54 to expand synchronously, so that the elastic buckle assembly 54 loses the limiting clamping of the connecting plate 15, and at this time the lifting rack 16 no longer clamps and fixes the gear 20, and the mounting plate 34 no longer rises, that is, the second winding drum 23 no longer rotates, and the second winding drum 23 axially limits the first winding drum 22 through the rotating shaft 21, that is, the first winding drum 22 no longer releases the driving steel cable 51;

[0045] At this time, the winch assembly 53 continues to reel in the driving steel cable 51, and then drives the first reel 22 to move along the direction of the fixed connecting rod 9 through the driving steel cable 51, and the first reel 22 drives the movable frame 18 to move, and the movable frame 18 drives the sliding cylinder 43 to move along the direction of the mounting slide rod 42, thereby compressing the second spring 44. At this time, the movable frame 18 drives the gear 20 to move along the direction of the fixed rack 14 through the connecting shaft 19. At this time, the gear 20 rotates under the drive of the fixed gear 20, and the lifting gear 20 is raised under the rotation of the gear 20. At this time, the goods move synchronously with the movement of the movable frame 18. When the goods move to the top of the cart 1, the movable frame 18 moves to the bottom of the mounting groove 13, and the winch assembly 53 no longer reels the driving steel cable 51. At this time, the movable frame 18 no longer moves, and the gear 20 no longer rotates. Under the action of gravity, the lifting rack 16 drops again to mesh with the gear 20, and then when the goods need to be put down , it is only necessary to reverse the winch assembly 53 to release the driving cable, and at the same time the staff pulls the safety handle 41 to release the safety lock assembly 56 to axially limit the second winding drum 23. At this time, the traction steel cable 33 is released under the action of the gravity of the goods, and the mounting plate 34 and the synchronous driving assembly 55 are no longer in contact. At this time, the synchronous driving assembly 55 drives the elastic buckle assembly 54 to extend, and then the connecting plate 15 is clamped again by the elastic buckle assembly 54, and then the movable frame 18 is limited and fixed again by the gear 20, so as to prevent the goods from shaking during the movement, and the traction steel cable 33 drives the second winding drum 23 to rotate, and the second winding drum 23 drives the first winding drum 22 to rotate through the rotating shaft 21, and the first winding drum 22 rotates and rewinds the driving steel cable 51, and the traction steel cable 33 is lowered through the mounting plate 34, and then the goods are placed on the cart 1, thereby completing the transfer of the goods, and the goods can be transported by the cart 1 at this time;

[0046] When the cargo needs to be unloaded, it is only necessary to reel in the driving steel cable 51 through the winch assembly 53 again to drive the cargo to rise. When the cargo rises to the top, the synchronous drive assembly 55 drives the safety lock assembly 56 to close again, so that the second winding disc 23 is axially limited and locked by the safety lock assembly 56. At the same time, the synchronous drive assembly 55 drives the elastic buckle assembly 54 to unfold synchronously, so that the elastic buckle assembly 54 loses the limit clamping of the connecting plate 15. At this time, the reverse winch assembly 53 can release the driving steel cable 51, and the second spring 4 The sliding cylinder 43 is pushed to move, and the sliding cylinder 43 drives the moving seat to move away from the cart 1, and drives the goods to move out of the cart 1. After that, when the goods move to the outermost end of the rotating mounting frame 10, the goods stop moving, and the staff pulls the safety handle 41 again to release the safety lock assembly 56 to axially limit the second winding drum 23. At this time, the traction steel cable 33 is released under the action of the gravity of the goods, and the traction steel cable 33 is lowered through the mounting plate 34 to lower the goods to the target point in front of the cart 1, thereby completing the transfer of the goods.

[0047] In one case of this embodiment, see Figure 8 and Fig. 9 The elastic buckle assembly 54 includes a fixed tube 25, a telescopic rod 26, and a telescopic buckle 27; the fixed frames 24 are fixedly connected on both sides of the mobile frame 18, the fixed tube 25 is fixedly connected to the top of the fixed frame 24, the telescopic rod 26 is slidably connected in the fixed tube 25, the telescopic buckle 27 is fixedly connected to one end of the telescopic rod 26 close to the connecting plate 15, the telescopic buckle 27 cooperates with the connecting plate 15, and the side of the telescopic buckle 27 away from the connecting plate 15 is set at an oblique angle, and a first spring 28 is set in the fixed tube 25, and the first spring 28 is sleeved on the telescopic rod 26;

[0048] The elastic buckle assembly 54 elastically pushes the telescopic buckle 27 through the setting of the first spring 28, thereby driving the telescopic buckle 27 to clamp above the connecting plate 15, thereby clamping and fixing the connecting plate 15 in the vertical direction. When the connecting plate 15 needs to be unlocked, the synchronous drive assembly 55 drives the telescopic rod 26 to slide out of the fixed tube 25, and the telescopic rod 26 drives the telescopic buckle 27 to slide into the fixed tube 25, compressing the first spring 28, thereby causing the telescopic buckle 27 to lose its clamping force on the connecting plate 15. When the synchronous drive assembly 55 loses driving force, the first spring 28 loses compression force, and the first spring 28 releases energy, thereby pushing the telescopic buckle 27 to extend out of the fixed tube 25, thereby clamping and fixing the connecting plate 15 again.

[0049] In one case of this embodiment, see Figure 8 and Fig. 9The synchronous drive assembly 55 includes an angled drive rod 30 and a drive connecting rod 31; the angled drive frame 29 is slidably connected in the fixed frame 24, and the end of the telescopic rod 26 away from the rotating mounting frame 10 is fixedly connected to the drive frame 29, and the drive frame 29 cooperates with the angled drive rod 30. The inclined side of the angled drive rod 30 is arranged on the side of the angled drive rod 30 away from the rotating mounting frame 10, and one end of the drive connecting rod 31 is fixedly connected to the angled drive rod 30, and the other end of the drive connecting rod 31 is installed with a contact roller 32, and the contact roller 32 cooperates with the mounting plate 34;

[0050] The synchronous drive assembly 55 drives the mounting plate 34 to rise and fall by pulling the steel cable 33. When the mounting plate 34 rises to contact with the contact roller 32, the mounting plate 34 drives the driving connecting rod 31 to rise through the contact roller 32. The driving connecting rod 31 drives the bevel driving rod 30 to extend from the fixed frame 24 to the driving frame 29. At this time, the inclined side of the bevel driving rod 30 drives the driving frame 29 to move by cooperating with the driving frame 29. The driving frame 29 drives the telescopic rod 26 to slide out of the fixed tube 25. Then, when the mounting plate 34 descends, the mounting plate 34 is no longer in contact with the contact roller 32. At this time, the bevel driving rod 30 is pulled out of the driving frame 29 under the action of gravity, and the driving frame 29 moves and resets under the drive of the telescopic rod 26.

[0051] In one case of this embodiment, see Figure 8 and Fig. 9 The safety lock assembly 56 includes a safety chuck 38, a synchronous connecting frame 37, and a latching tooth 40; the outer wall of the second winding disk 23 is fixedly connected with a safety chuck 38, and a plurality of groups of equally spaced safety slots 39 are arranged in the safety chuck 38; the driving connecting rod 31 is fixedly connected with a spring plate 36, and the synchronous connecting frame 37 is fixedly connected with the spring plate 36; the synchronous connecting frame 37 is fixedly connected with a latching tooth 40, and the latching tooth 40 and the safety slot 39 are slidably connected to each other, and the synchronous connecting frame 37 is fixedly connected with a safety handle 41;

[0052] The safety lock assembly 56 drives the spring plate 36 and the synchronous connecting frame 37 to rise and fall by driving the connecting rod 31. When the mounting plate 34 drives the synchronous connecting frame 37 to rise by the synchronous driving rod, the synchronous connecting frame 37 drives the latching teeth 40 to rise and insert into a group of safety latching grooves 39. At this time, the second winding drum 23 can be axially limited by the mutual cooperation between the latching teeth 40 and the safety latching grooves 39. At this time, the second winding drum 23 cannot rotate, that is, the second winding drum 23 cannot release the traction steel cable 33, and the mounting plate 34 cannot descend, that is, the latching teeth 40 cannot escape from the safety latching grooves 39. If the latching teeth 40 cannot escape from the second winding drum 23, the traction steel cable 33 cannot be rotated to release the traction steel cable 33, thereby realizing the axial locking of the second winding drum 23, thereby preventing the goods from accidentally falling off during the movement.

[0053] And when the goods need to be released, the staff only needs to pull the safety handle 41 to drive the synchronous connecting frame 37 to rotate and press down. At this time, the spring plate 36 is deformed by the force, and the synchronous connecting frame 37 drives the latch tooth 40 to press down, and then drives the latch tooth 40 to slide out of the safety latch groove 39, thereby releasing the axial lock of the second winding drum 23. At this time, the traction cable 33 can be released by rotating the second winding drum 23.

A first guide pulley 45 is installed on the side of the rotating connecting rod 11 close to the rotating rod 7, a second guide pulley 46 is installed on the side of the rotating rod 7 close to the rotating connecting rod 11, and a third guide pulley 47 is installed on the other side of the rotating rod 7. A wire port is provided between the second guide pulley 46 and the third guide pulley 47. 48, the driving steel cable 51 passes through the first guide pulley 45, the second guide pulley 46, the wire port 48, and the third guide pulley 47 in sequence and is fixedly connected to the winch 50, the winch assembly 53 first drives the driving steel cable 51 to be wound or released through the driving motor 52, and the driving steel cable 51 is rolled and guided by the first guide pulley 45, the second guide pulley 46, the wire port 48, and the third guide pulley 47 during the movement, thereby preventing the driving steel cable 51 from rubbing against the rigidity of the component and affecting the use of the driving steel cable 51.
