Detailed implementation manners

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, and therefore only showing the components related to the present invention.

[0037] Embodiment 1 As a specific implementation manner, referring to Figures 1 - 2 , Figure 5 , the present invention provides a bulk bag loading system, including: A crane 30; A buffer unit, including a connecting frame 32 connected to the crane 30 and a rigid telescopic rod 310 disposed on the connecting frame 32, and the upper end of the rigid telescopic rod 310 is connected to the hoisting trolley of the crane 30; A sliding assembly 7, connected to the connecting frame 32, including a vertically disposed rotating shaft 702, a horizontally disposed guide rail 708 disposed at the lower end of the rotating shaft 702, and a driving member 709 for driving the rotating shaft 702 to swing around its axis; A hook assembly 8, movably disposed on the guide rail 708 along the guiding direction of the guide rail 708.

[0038] Specifically, it should be noted that the crane 30 adopted in the present application is a common equipment such as an overhead crane in the art. Specifically, an overhead crane is selected. It can be understood that the overhead crane includes a traveling track, the overhead crane truss travels along the traveling track, and a trolley travels on the truss. A winch is disposed on the trolley, and the winch drives a steel wire rope 31 to achieve the purpose of lifting. In the present application, a buffer unit is disposed at the lower end of the steel wire rope 31. The buffer unit includes a connecting frame 32. The rigid telescopic rod 310 connected to the connecting frame 32, and the upper end of the rigid telescopic rod 310 is connected to the hoisting trolley. The rigid telescopic rod 310 can lift and lower together with the connecting frame 32. The rigid telescopic rod 310 has rigidity. Therefore, when the trolley starts and stops, it can provide a buffer force to the lower connecting frame 32 and reduce the swing of the connecting frame 32.

[0039] Further, a rotating shaft 702 is disposed below the connecting frame 32, and a horizontal guide rail 708 is disposed below the rotating shaft 702, so that the angle of the guide rail 708 can be adjusted by adjusting the rotation angle of the rotating shaft 702, so that the angle of the hook assembly 8 disposed on the guide rail 708 can be adjusted, which is convenient for the hook assembly 8 to grasp the bulk bag. The hook assembly 8 is movably disposed on the guide rail 708 and can move horizontally, which is more conducive to grasping the bulk bag.

[0040] Further, as a specific implementation manner, referring to Figures 15 - 17, the specific structure of the gradual sliding is as follows: a box body 701 is provided at the lower end of the rotating shaft 702. The guide rails 708 include two groups respectively arranged at both ends of the box body 701, and a set of hook assemblies 8 are provided on each group of guide rails 708. A rigid housing 801 is provided below the buffer unit. The rotating shaft 702 is rotatably arranged inside the housing 801. The housing 801 is rotatably arranged and axially anti-creeperly cooperates with the box body 701, and the axis of rotation of the box body 701 is coaxial with the axis of the rotating shaft 702. The rotation modes of the box body 701 and the housing 801 adopt the prior art, and the specific structure thereof is not limited herein as long as the working purpose can be achieved. A driving member 709 is provided on the side wall of the housing 801. The driving member 709 is selected from any one of an electric push rod, a pneumatic push rod, and a hydraulic push rod. The driving member 709 is not provided with a first crank 703, and the first crank 703 is connected to the rotating shaft 702, so as to drive the rotating shaft 702 to swing around its own axis, and the rotating shaft 702 is connected to the box body 701, so as to be able to drive the box body 701 to swing in the horizontal direction.

[0041] Continue to refer to Figures 15 - 17 , a lead screw 707 is arranged in the box body 701 parallel to the guide rail 708. Each hook assembly 8 is provided with a lead screw nut 811 threadedly connected to the lead screw 707, and the lead screw 707 is drivingly connected to a first servo motor 705. Specifically, two groups of guide rails 708 are respectively arranged at both ends of the box body 701. A sliding member 11 is slidably arranged on the guide rail 708 in a guiding manner. Each group of guide rails 708 is arranged in parallel at intervals of two. A lead screw 707 is rotatably arranged between the two guide rails 708. An input shaft 704 is rotatably arranged in the middle area of the box body 701. The input shaft 704 is drivingly connected to a first servo motor 705. Both ends of the input shaft 704 are drivingly connected to the two lead screws 707 through couplings, so as to achieve the purpose of driving the lead screw 707. The two lead screws 707 are reverse lead screws 707. The hook assemblies 8 are respectively connected to the sliding member 11 and the lead screw nut 811, so as to be able to drive the hook assemblies 8 to move towards and away from each other through the first servo motor 705, achieve the effect of adjusting the distance between the two hook assemblies 8, and be able to adaptively adjust according to the distance between the two ton bags. When specifically grasping the ton bags, control the hook assemblies 8 to open, and then adjust the positions of the two hook assemblies 8 to grasp the suspension straps of the ton bags, improve and enhance the efficiency of ton bag grasping, and improve the loading efficiency.

[0042] Further, as a specific implementation manner, refer to Figure 18 、 Figure 19, the specific structure and working mode of the grab hook assembly are as follows: The grab hook assembly 8 includes a rotatably mounted locking rod 802 and a hook 803. The rotating shafts of the locking rod 802 and the hook 803 are connected with meshing transmission gears 804. The number of the transmission gears 804 is two. The two transmission gears 804 are respectively connected with the rotating shafts of the locking rod 802 and the hook 803, and the two transmission gears 804 are meshed with each other. Therefore, when one of the locking rod 802 and the hook 803 rotates, the other rotates in the opposite direction. In this way, the locking rod 802 and the hook 803 can open and close, and thus the grabbing and releasing of the ton bags can be realized. The locking rod 802 is located on the opening side of the hook 803, and a notch for cooperating with the hook 803 is provided at the lower end of the locking rod 802. When closed, the lower end of the hook 803 passes through this notch.

[0043] The rotating shaft of the locking rod 802 is located at the upper end of the locking rod 802; the rotating shaft of the hook 803 is located at the upper end of the hook 803. A limit bolt 810 is threaded through the upper part of the locking rod 802. When the grab hook assembly 8 is closed, the end of the limit bolt 810 abuts against the upper part of the hook 803, playing a role in limiting the closing angle in the closed state.

[0044] The grab hook assembly 8 includes a housing 801 and a power component. The housing 801 includes upper and lower parts. The lower part of the housing 801 supports the locking rod 802 and the hook 803, and the upper end of the upper part of the housing 801 cooperates with the lead screw 707. The power component includes a second servo motor 805 and a reducer 806 driven by the second servo motor 805. The reducer 806 is installed on one side of the housing 801.

[0045] The power component drives the rotating shaft of the hook 803 to rotate through a crank-rocker mechanism. The crank-rocker mechanism includes a second crank 807, a rocker 808 and a connecting rod 809. The second crank 807 is connected with the output shaft of the reducer 806, the rocker 808 is connected with the rotating shaft of the hook 803, and the connecting rod 809 is hinged between the second crank 807 and the rocker 808. In this way, the power component can swing the hook 803 through the crank-rocker mechanism, and at the same time swing the locking rod 802 in the opposite direction through the meshing transmission gears 804, so as to make the closing and separating actions, and thus realize the grabbing and releasing of the ton bags.

[0046] Embodiment 2 As a specific implementation manner, refer to Figure 3 , Figure 4 , Figures 6 - 14 , the present invention provides a ton bag loading system. As a further improvement, different from Embodiment 1, the buffer unit includes a buffer assembly 34, and the buffer assembly 34 includes: A top plate 340, connected to the connecting frame 32; A third gear shaft 342, vertically arranged on the top plate 340; The damping assembly 37 is horizontally rotatably arranged below the top plate 340 and includes a fifth bevel gear 3740 drivingly connected to the third gear shaft 342; The turntable 38 is horizontally rotatably arranged below the damping assembly 37 and is drivingly connected to the damping assembly 37; The connecting plate 36 is vertically guided and arranged below the top plate 340. The hook assembly 8 is connected to the connecting plate 36. The turntable 38 has a locked state and a released state. The connecting plate 36 is configured to be able to drive the turntable 38 to switch from the released state to the locked state when the hook assembly 8 grabs materials.

[0047] Specifically, referring to Figure 5 , the buffer unit includes a connecting component 35 and a buffer component 34, both arranged on the connecting frame 32. The connecting component 35 is fixedly connected to the lower end of the rigid telescopic rod 310, and the upper end is hinged to the lifting trolley through a cross shaft. By this setting method, when the crane 30 hoists the ton bag and moves or stops, it drives the rigid telescopic rod 310 to swing. When swinging, the swinging action can be transmitted to the buffer component 34 through the connecting component 35, driving the third gear shaft 342 to rotate. The third gear shaft 342 drives the damping assembly 37 to rotate. When there is a ton bag hanging below the hook 803, under the action of the gravity of the ton bag, the connecting plate 36 is pulled down a certain distance, so that the turntable 38 is in the locked state. In the locked state, the turntable 38 cannot rotate around its own axis, and at this time, the damping assembly 37 is locked through the turntable 38, and the damping assembly 37 also cannot rotate around itself. At this time, driving the work of the damping assembly 37 itself, the damping assembly 37 works to buffer and damp the swing amount, so as to be able to reduce the swing amplitude.

[0048] Furthermore, referring to Figures 10 - 12 , the damping assembly 37 includes a metal side wall, and two second plates 344 are arranged on the opposite two side walls. The first plates 343 are arranged on the other two side walls; By the above setting method, the connecting plate 36 is provided with a rigid rod 361 that is vertically guided and matched with the first plate 343 and the second plate 344. A limiting plate 362 is arranged above the rigid rod 361, and a supporting compression spring 345 is arranged above the second plate 344. The supporting compression spring 345 abuts against the limiting plate 362, and the supporting compression spring 345 can provide a supporting force for the connecting plate 36. When there is no hoisting of the ton bag, under the elastic force of the supporting compression spring 345, the turntable 38 is kept in the released state. At this time, the turntable 38 can rotate around its own axis, so that the hook assembly 8 can swing freely at this time, facilitating the hook assembly 8 to be in the vertical state under its own gravity, which is more conducive to grabbing the ton bag.

[0049] Furthermore, as a preferred implementation manner, referring to Figure 11, the second plate 344 is located below the first plate 343. A support sleeve 346 is provided on the upper surface of the second plate 344, and the upper surface of the support sleeve 346 is flush with the upper surface of the first plate 343. With this arrangement, when lifting the ton bag, the four rigid rods 361 can be supported simultaneously by the support sleeve 346 and the upper surface of the first plate 343, improving the support stability.

[0050] Further, as a specific implementation manner, refer to Figure 12 , Figure 13 , a friction sleeve 382 is coaxially arranged on the turntable 38. A horizontal guide rod 390 is arranged below the turntable 38. One end of the horizontal guide rod 390 is drivingly connected to the connecting plate 36, and the other end is provided with an arc-shaped friction plate adapted to the friction sleeve 382. Specifically, the rectangular housing includes a detachable bottom plate. A support shaft 381 is arranged on the bottom plate. The turntable 38 is rotatably fitted with the support shaft 381. A friction sleeve 382 is arranged on the lower surface of the turntable 38 around the axis. Around the friction sleeve 382, at least two horizontal guide rods 390 are arranged on the bottom plate along the direction away from the axis of the friction sleeve 382. The horizontal guide rods 390 are drivingly connected to the connecting plate 36 and can drive the horizontal guide rods 390 to move axially. When the annular friction plate 392 contacts the outer side wall of the friction sleeve 382, the turntable 38 is locked, and this is the locked state. When the annular friction plate 392 is separated from the friction sleeve 382, it is the released state.

[0051] Further, as a specific implementation manner, refer to Figure 12 , Figure 13 , a second inclined surface 3930 is arranged at the end of the horizontal guide rod 390, and the connecting plate 36 is connected with a first inclined surface 3910 drivingly connected to the second inclined surface 3930.

[0052] Further, the second inclined surface 3930 is arranged on the side of the first inclined surface 3910 close to the annular friction plate 392. A return spring 394 is arranged between the horizontal guide rod 390 and the top plate 340, and the return spring 394 can provide an elastic force for the horizontal guide rod 390 to move towards the direction close to the first inclined surface 3910.

[0053] Specifically, a force-receiving member 393 is provided at one end of the horizontal guide rod 390. The force-receiving member 393 is provided with a second inclined surface 3930. A channel 3401 is provided on the side wall of the metal shell. A fixing sleeve 391 is sleeved on the rigid rod 361. The fixing sleeve 391 can be fixedly connected to the rigid rod 361 through a locking screw. A first inclined surface 3910 that is drivingly connected to the second inclined surface 3930 is provided at the end of the rigid sleeve. When the connecting plate 36 moves downward, the horizontal guide rod 390 can be driven to move through the cooperation of the first inclined surface 3910 and the second inclined surface 3930, so that the annular friction plate 392 contacts the friction sleeve 382 for locking. When the ton bag is not lifted, it rebounds under the elastic force of the support compression spring 345. At this time, under the elastic force of the return spring 394, the horizontal guide rod 390 returns to its original position, thus switching to the release state.

[0054] Further, as a specific implementation manner, referring to Figures 6 - 9 , the buffer unit further includes a connection assembly 35, and the connection assembly 35 includes: A first plate 343, which is connected to the lower end of the rigid telescopic cylinder and the lower end of the rigid telescopic rod 310; A rigid frame 350, which is rotatably connected to the top plate 340, and the axis of rotation is horizontally arranged; A first bevel gear 354, which is coaxially arranged with the axis of rotation of the rigid frame 350 and is rotationally matched with the rigid frame 350, and is drivingly connected to the third gear shaft 342; There are two half shafts 355. A second bevel gear 3550 that meshes with the first bevel gear 354 is provided at one end, and a spline sleeve 3520 is connected to the other end. The first plate 343 is connected to the two spline sleeves 3520.

[0055] Specifically, the rigid frame 350 includes two connecting shafts 3501 arranged at intervals. The connecting shafts 3501 are rotatably connected to the ear plates 341. The first bevel gear 354 is arranged between the two connecting shafts 3501. A plug shaft 3540 that rotates in cooperation with the first bevel gear 354 is inserted into the connecting shaft 3501. Two plug sleeves are also arranged on both sides of the first bevel gear 354. A half shaft 355 is inserted and rotatably arranged in the plug sleeve. A spline is arranged at the end of each half shaft 355 away from the first bevel gear 354, and is in plug-in fit with a spline sleeve 3520. The spline sleeve 3520 is connected to a swing arm 352. The rigid plate 353 is detachably and fixedly connected to the two swing arms 352. The rigid plate 353 is fixedly connected to the lower end of the rigid telescopic rod 310. The rigid telescopic rod 310 can be made of a steel cylinder with a multi-stage guiding plug-in fit. During actual use, the upper end of the rigid telescopic rod 310 is rotatably connected to the hoisting trolley through a cross shaft. One shaft of the hoisting cross shaft is arranged parallel to the half shaft 355, and the other shaft is parallel to the axis of the first bevel gear 354. Through the above setting method, when the ton bag swings during hoisting, it can drive the rigid telescopic rod 310 to swing. At this time, the rigid telescopic rod 310 can swing around the rotation axis of the rigid frame 350 or the axis of the half shaft 355. When swinging around the rotation axis of the rigid frame 350, it can drive the first bevel gear 354 to rotate around the axis, thereby driving the third gear shaft 342 to rotate. The third gear shaft 342 drives the fourth bevel gear 3421 to rotate. The fourth bevel gear 3421 meshes with the fifth bevel gear 3740. When hoisting the ton bag, the turntable 38 is in a locked state. The damping assembly 37 is provided with a third bevel gear 372. The third bevel gear 372 is drivingly connected to the toothed ring 380 on the turntable 38. At this time, the damping assembly 37 is in a damping state, and a damping force is provided by the damping assembly 37 during the rotation process to reduce the swing amount.

[0056] When the rigid telescopic rod 310 swings around the axis of the half shaft 355, it can also drive the first bevel gear 354 to rotate around the axis, driving the third gear shaft 342 to rotate, so as to achieve the damping and buffering effect.
