Description

Technical Field

[0001] This utility model relates to the field of ton bag loading and unloading technology, specifically to a hook for loading and unloading ton bags. Background Technology

[0002] Ton bags, also known as flexible container bags, bulk bags, space bags, etc., are a type of medium-sized bulk container and a type of container unit. They are characterized by large volume, light weight, and easy loading and unloading. They are also simple in structure, lightweight, foldable, take up little space when empty, and are inexpensive. After the ton bag is filled with goods, a lifting device is needed to lift the ton bag for loading operations.

[0003] In the prior art, patent publication number CN202223536674.2 discloses an automatic release electric ton bag hook, including: a load-bearing structure, a positioning screw, a hollow rotary motor, and a movable stop pin. The positioning screw is installed in the lower middle of the load-bearing structure, and the hollow rotary motor and self-locking nut are installed in the upper middle of the load-bearing structure. The movable stop pin is connected below the positioning screw, and a switch box is installed on the side.

[0004] The above-mentioned ton bag hooks have some problems in actual use. For example, the entire hook is inconvenient to assemble and disassemble. The hook relies on the strength of the movable stop pin to block the lifting rope of the ton bag. The ton bag has a large weight and may crush the stop pin, causing it to come off the hook. Therefore, we propose a hook for loading and unloading ton bags. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 This embodiment provides a technical solution: a hook for loading and unloading ton bags, including a mounting box 1, a lifting mechanism 4, and a quick-assembly mechanism 9;

[0025] Mounting box 1: An isolation plate 2 is fixedly connected to its middle part; a front sealing plate 3 is provided on the front side of mounting box 1; and a rear sealing plate 5 is fixedly connected to the rear side of mounting box 1.

[0026] Lifting mechanism 4: It includes rotating columns 41, sector gears 42, rectangular inserts 43, rotating seats 44, and rectangular holes 45. The rotating columns 41 are symmetrically rotated and connected to the front side of the isolation plate 2. Sector gears 42 are fixedly connected to the rear side of the outer arc surface of the two rotating columns 41 respectively. The two sector gears 42 are fitted together. The front ends of the two rotating columns 41 are fixedly connected to the rectangular inserts 43 respectively. The middle part of the two rotating seats 44 is provided with rectangular holes 45 respectively. The outer surfaces of the two rectangular inserts 43 are respectively inserted into the interior of the rectangular holes 45 corresponding to the longitudinal position. The lower end of the left rotating seat 44 is fixedly connected to a hook 10. The lower end of the right rotating seat 44 is fixedly connected to a Y-shaped limiting plate 11. The rear side of the outer arc surface of the right rotating column 41 is fixedly fitted with a worm gear 6. The left and right interiors of the mounting box 1 are... A worm gear 7 is rotatably connected to the lower rear side of the mounting box 1, and a worm wheel 6 meshes with the worm gear 7. A motor 8 is fixedly connected to the lower rear side of the right side of the mounting box 1. The output shaft of the motor 8 is fixedly connected to the right end of the worm gear 7, and the input end of the motor 8 is electrically connected to the output end of an external controller. Mounting lugs are symmetrically fixedly connected to the upper surface of the mounting box 1. Pointers are fixedly connected to the front sides of the two toggle heads 48 respectively. When both pointers are pointing downwards, it indicates that the strip-shaped limiting insert 49 is in a vertical state and can be smoothly inserted into the strip-shaped limiting slot 46. When the hook is needed, the rotating base 44 can be manually lifted, and guided by the rectangular insert 43 and the rectangular hole 45, the two rotating bases 44 are inserted into the outer surface of the rectangular insert 43. Then the front sealing plate 3 can be manually lifted and fastened. On the front side of the mounting box 1, the horizontal insert 91 is inserted into the horizontal slot 92, and the bottom insert 94 is inserted into the bottom limit bracket 93. At this time, the strip-shaped limit inserts 49 on the rear side of the front rotating column 47 are respectively inserted into the strip-shaped limit slots 46. At this time, the external controller can be adjusted, the motor 8 runs, and the output shaft of the motor 8 rotates in both directions, thereby driving the worm gear 7 to rotate in both directions, which in turn drives the right rotating column 41 to rotate in both directions through the worm wheel 6. The maximum rotation angle of the right rotating column 41 is maintained at about 60 degrees. When the right rotating column 41 rotates 60 degrees clockwise, it will drive the right rotating seat 44 to rotate 60 degrees clockwise around the central axis of the right rotating column 41, until the right rotating seat 44 rotates 60 degrees clockwise. The lower left slope of 4 is pressed against the upper right slope of the bottom limiting bracket 93 to prevent the right rotating seat 44 from continuing to rotate. When the right rotating seat 44 rotates counterclockwise by 60 degrees, the right side of the right rotating seat 44 contacts the right side of the mounting box 1, limiting the maximum angle of counterclockwise rotation of the right rotating seat 44. As the right rotating seat 44 rotates, it drives the right sector gear 42 to rotate around the central axis of the right rotating column 41. The right sector gear 42 maintains a meshing relationship with the left sector gear 42 through a portion of the teeth in the sector area. The tooth surface of the right sector gear 42 contacts the tooth surface of the left sector gear 42. Since the base circle size is fixed, the position and direction of the meshing line are constant and rotate with the right sector gear 42.The left-side sector gear 42 drives the left-side rotating column 41 in the opposite direction. The two sector gears 42 are the same size (here, the right-side sector gear 42 is considered A, and the left-side sector gear 42 is considered B; the tooth surface of A pushes the tooth surface of B through static friction, and B rotates counterclockwise with A. According to the basic law of involute meshing, the two teeth are always meshed, and the transmission ratio is constant). This, in turn, drives the left-side rotating seat 44 to rotate around the central axis of the left-side rotating column 41, thereby controlling the hook 10 to rotate around the central axis of the left-side rotating column 41, and the Y-shaped limiting plate 11 to rotate in the opposite direction around the central axis of the right-side rotating column 41. This controls the opening and closing of the hook 10 and the Y-shaped limiting plate 11, allowing the mounting lugs on the upper side of the mounting box 1 to be installed on the external crane. The external crane is then controlled to move the hook position, and the hook 10 and the Y-shaped limiting plate 11 are controlled to open and close, thus achieving the function of lifting the ton bag.

[0027] Quick-installation mechanism 9: Located inside the front of the mounting box 1, quick-installation mechanism 9 includes a horizontal insert 91, a horizontal slot 92, a bottom limiting bracket 93, and a bottom insert 94. A horizontal slot 92 is provided on the front of the upper surface of the mounting box 1. A horizontal insert 91 is inserted into the horizontal slot 92. The front end of the horizontal insert 91 is fixedly connected to the upper rear side of the front sealing plate 3. A bottom limiting bracket 93 is fixedly connected to the lower front side of the partition plate 2. A bottom insert 94 is inserted into the bottom limiting bracket 93. The front end of the bottom insert 94 is connected to the upper rear side of the front sealing plate 3. The lower side is fixedly connected. Bolt slots are respectively provided on the middle of the upper surface of the transverse insert 91, the upper and lower side walls of the transverse slot 92, the upper and lower sides of the bottom limit frame 93, and the middle of the upper surface of the bottom insert 94. At this time, the bolt slots in the middle of the upper surface of the transverse insert 91, the upper and lower side walls of the transverse slot 92, the upper and lower sides of the bottom limit frame 93, and the middle of the upper surface of the bottom insert 94 are vertically aligned. Then, the external bolts are picked up and screwed into the bolt slots to complete the fixing of the front sealing plate 3.

[0028] The working principle of the hook for loading and unloading ton bags provided by this utility model is as follows: When the hook is needed, the rotating base 44 can be manually lifted, and guided by the rectangular insert post 43 and the rectangular hole 45, the two rotating bases 44 are inserted into the outer surface of the rectangular insert post 43. Then, the front sealing plate 3 can be manually lifted and fastened to the front of the mounting box 1. The transverse insert 91 is inserted into the interior of the transverse slot 92, and the bottom insert 94 is inserted into the interior of the bottom limiting bracket 93. At this time, the strip limiting insert 49 on the rear side of the front rotating post 47 is inserted into the interior of the strip limiting slot 46. At this time, the bolt groove in the middle of the upper surface of the transverse insert 91, the bolt groove on the upper and lower side walls of the transverse slot 92, and the bottom... The bolt slots on the upper and lower sides of the limit bracket 93 and the bolt slot in the middle of the upper surface of the bottom insert 94 are vertically aligned. Then, the external bolts are screwed into the bolt slots to fix the front sealing plate 3. At this point, the external controller can be adjusted, and the motor 8 will operate. The output shaft of the motor 8 will rotate in both directions, thereby driving the worm gear 7 to rotate in both directions. This, in turn, drives the right-side rotating column 41 to rotate in both directions via the worm wheel 6. The maximum rotation angle of the right-side rotating column 41 is maintained at approximately sixty degrees. When the right-side rotating column 41 rotates sixty degrees clockwise, it will drive the right-side rotating seat 44 to rotate sixty degrees clockwise around the central axis of the right-side rotating column 41 until the right side... The lower left inclined surface of the rotating base 44 is pressed against the upper right inclined surface of the bottom limiting bracket 93 to prevent the rotating base 44 from continuing to rotate. When the rotating base 44 rotates counterclockwise by 60 degrees, the right side of the rotating base 44 contacts the right side of the mounting box 1, limiting the maximum angle of counterclockwise rotation of the rotating base 44. As the rotating base 44 rotates, it drives the right sector gear 42 to rotate around the central axis of the right rotating column 41. The right sector gear 42 maintains a meshing relationship with the left sector gear 42 through a portion of the teeth in the sector area. The tooth surface of the right sector gear 42 contacts the tooth surface of the left sector gear 42. Since the base circle size is fixed, The position and direction of the meshing line are constant. As the right sector gear 42 rotates, it drives the left sector gear 42 to rotate the left rotating column 41 in the opposite direction. This, in turn, drives the left rotating seat 44 to rotate around the central axis of the left rotating column 41. This, in turn, controls the hook 10 to rotate around the central axis of the left rotating column 41. The Y-shaped limiting plate 11 rotates in the opposite direction around the central axis of the right rotating column 41. This controls the opening and closing of the hook 10 and the Y-shaped limiting plate 11. At this time, the mounting lug on the upper side of the mounting box 1 can be installed on the external crane. The external crane can be controlled to move the position of the hook and control the opening and closing of the hook 10 and the Y-shaped limiting plate 11 to achieve the function of lifting the ton bag.

[0029] It is worth noting that the motor 8 disclosed in the above embodiments can be freely configured according to the actual application scenario. It is recommended to use a 130BL series servo motor for motor 8, and the external controller controls the operation of motor 8 using methods commonly used in the prior art.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
