Description

Technical Field

[0001] The utility model belongs to the technical field of ton bag slings, in particular to a ton bag sling with an automatic hook-detaching function and an anti-slip function. Background Art

[0002] Ton bags play a great role in the transportation of factory materials, packaging and transportation of agricultural products and mineral products, such as the loading and unloading, lifting and storage of bulk cement, grain, various agricultural products, chemical raw materials, feed, minerals and other powdery and granular objects. It can be seen that ton bags are very useful and provide great convenience for the packaging and handling of large-volume and large-tonnage goods.

[0003] The Chinese patent with the publication number CN215402594U discloses a sling for automatic unhooking of ton bags, which is composed of four hooks, a support seat, and two bayonet pins. The characteristics are as follows: the support seat is composed of two L-shaped brackets, each L-shaped bracket has two hooks fixedly suspended at the long arm end, and the two L-shaped brackets are connected into a whole through two bayonet pins at the short arm end, and the two bayonet pins can be docked with the forklift door frame. A counterweight is added to the tail of each hook. When there is a heavy object on the hook, the hook is in a vertical state. When the heavy object on the hook falls, the counterweight at the tail of the hook falls, and the hook rises, automatically unloading the heavy object on the hook. However, the ton bag sling is easy to shake after lifting, and the ton bag is easy to fall off during the shaking process, and the safety is low.

[0004] A Chinese patent with publication number CN220926054U discloses an automatic unhooking sling for ton bags, comprising a fixed block, a top plate is arranged on the top surface of the fixed block, a mounting frame is arranged on the lower surface of the fixed block, a side frame is fixedly connected to the right side surface of the mounting frame; a hook body, the hook body is mounted on the lower surface of the mounting frame, an air inlet is opened on the top surface of the side frame, a first mounting column is arranged inside the hook body, a clamping block is arranged on the lower surface of the side frame, a second connecting column is arranged inside the clamping block, and an air bottle is arranged on the lower surface of the top plate. This patent solves the safety problem of the ton bag being easily unhooked due to shaking in the Chinese patent with the publication number CN215402594U. However, in this patent, by pressing the button, the solenoid valve will be opened, and the compressed air will enter the inside of the air inlet from the air bottle through the filter and the pressure reducing valve, and then enter the inside of the connecting pipe and the air inlet pipe through the air inlet. Then the resistance rod will lift up and loosen the hook body, so that the hook body will pop open, the hook body will unhook, the pneumatic hook safety pin will open, the hook head will open upward, the sling or nylon rope will fall, and the unhooking and unloading operation will be completed, realizing fast automatic unhooking. Therefore, the automatic unhooking of this patent requires electric drive, which increases energy consumption, and has more structures, which is prone to failure and delays production.

[0005] Therefore, a ton bag sling with automatic hook removal and anti-drop function is proposed. Utility Model Content

[0006] To solve the above technical problems, the utility model provides a ton bag sling with an automatic hook detaching and hooking function and anti - detachment function.

[0008] A beam body;

[0009] A lifting assembly symmetrically and fixedly connected to the top surface of the beam body for lifting the beam body;

[0010] A plurality of hanging assemblies uniformly arranged on the beam body. Each hanging assembly includes a safety catch and a hook. The middle part of the safety catch is hinged to the beam body. One end of the safety catch is hinged to the middle part of the hook and extends outward with a plug. One end of the hook is a hook for lifting the ton bag, the opening of the hook corresponds to the plug, and the other end is a first counterweight arm.

[0011] Preferably, the mass and length of the first counterweight arm match those of the hook, so that when the hook is unloaded, the first counterweight arm and the hook are in a horizontal state.

[0012] Preferably, the plug is arranged on the side of the safety catch away from the hook, and the bottom surface of the plug is inclined.

[0013] Preferably, the end of the safety catch away from the hook is a second counterweight arm. The mass and distance between the second counterweight arm, the hook and the plug are matched, so that when the hook is unloaded, the bottom surface of the plug is horizontal.

[0014] Preferably, mounting plates are fixedly connected to both sides of the beam body, and a plurality of the safety catches are evenly hinged to the mounting plates on both sides.

[0015] Preferably, the distance between adjacent safety catches is set according to the width of the ton bag.

It is evenly arranged on the beam body and can lift multiple ton bags at one time, thereby improving the efficiency of lifting and transportation. The hook includes a curved hook and a first counterweight arm. The curved hook is used for hanging ton bags. When unloaded, the first counterweight arm makes the opening of the curved hook face the horizontal side through its own weight. At this time, the plug on the insurance card is flush with the first counterweight arm, thereby making way for the opening of the curved hook, which is convenient for the sling of the ton bag to enter the curved hook. After the ton bag is hung on the curved hook, because the weight of the ton bag is much greater than the weight of the first counterweight arm, the curved hook can be rotated downward to lift the ton bag, and the side of the insurance card with the plug also rotates downward, thereby making the curved hook and the plug butt with each other, and the plug blocks the opening of the curved hook to prevent the ton bag in the curved hook from falling off, thereby improving the safety during the lifting process. During unloading, the ton bag contacts the ground and the weight of the ton bag is not applied to the hook. The hook and the insurance card return to the initial no-load state due to the weight of their own first counterweight arm. The hook opening opens and the beam moves laterally.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] To make the above - mentioned objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Embodiment 1

[0034] Refer to Figures 1 to 4 As shown, this embodiment provides a ton bag hanger with an automatic hook and anti - detachment function, including:

[0035] Beam body 1;

[0036] Lifting assembly 2, symmetrically and fixedly connected to the top surface of the beam body 1 for lifting the beam body 1;

[0037] A number of hanging assemblies, evenly arranged on the beam body 1. The hanging assembly includes a safety card 3 and a hook 4. The middle part of the safety card 3 is hinged to the beam body 1, one end of the safety card 3 is hinged to the middle part of the hook 4 and extends outward with a plug 5; one end of the hook 4 is a hook bend 41 for lifting the ton bag, the opening of the hook bend 41 is arranged corresponding to the plug 5, and the other end is a first counterweight arm 42.

[0038] A lifting assembly 2 is arranged on the top of the beam body 1, and the lifting assembly 2 is convenient for hanging the hook 4 of the crane, so that the entire beam body 1 can be lifted stably. The hanging assembly at the bottom of the beam body 1 is used to hang ton bags, which are evenly arranged on the beam body 1, and multiple ton bags can be lifted at one time, thereby improving the efficiency of lifting and transportation; the hook 4 includes a curved hook 41 and a first counterweight arm 42, and the curved hook 41 is used to hang the ton bag. When it is empty, the first counterweight arm 42 makes the opening of the curved hook 41 face the horizontal side through its own weight, and at this time, the safety card 3 The plug 5 is flush with the first counterweight arm 42, thereby leaving the opening of the hook 41, so that the sling of the ton bag can enter the hook 41; after the ton bag is hung on the hook 41, because the weight of the ton bag is much greater than the weight of the first counterweight arm 42, the hook 41 can rotate downward to lift the ton bag, and the side of the insurance card 3 with the plug 5 also rotates downward, so that the hook 41 and the plug 5 are connected to each other, and the plug 5 blocks the opening of the hook 41 to prevent the ton bag in the hook 41 from falling off, thereby improving the safety during lifting. When unloading, the ton bag contacts the ground, and the weight of the ton bag is not applied to the hook 41. The hook 41 and the insurance card 3 return to the initial unloaded state due to the weight of the first counterweight arm 42, the hook 41 opens, and the beam body 1 is moved laterally, and the ton bag sling can be removed from the opening of the hook 41 to achieve automatic unhooking.

[0039] The ton bag sling in the utility model can realize automatic hook removal and has an anti-drop function during the lifting process; multiple hanging components are arranged on the beam body 1, multiple ton bags can be lifted at one time, and the distance between the hanging components can be adjusted according to the size of the ton bag, which has stronger adaptability.

[0040] Furthermore, the lifting assembly 2 includes two corresponding mounting ears 21, the two mounting ears 21 are fixedly connected to the top surface of the beam body 1, a first pin shaft 22 is inserted between the two mounting ears 21, and the head of the first pin shaft 22 passes through the two mounting ears 21 and is threadedly connected with a first locking nut 23. The lifting hook of the crane is hooked on the first pin shaft 22 to lift the beam body 1.

[0041] According to a further optimization scheme, the mass and length of the first counterweight arm 42 match those of the hook 41, so that when the hook 4 is unloaded, the first counterweight arm 42 and the hook 41 are in a horizontal state.

[0042] When unloaded, the gravity of the first counterweight arm 42 and the hook 41 on both sides of the hinge point multiplied by their corresponding force arms respectively obtains equal torques. At this time, the two sides of the hinge point seem to maintain balance, and the opening of the hook 41 faces one side, which is convenient for the sling of the ton bag to enter the hook 41. At this time, any object hung on the hook 41 will increase the weight of the hook 41, which will cause the hook 41 to rotate downward and then dock with the plug 5 to lift the object. This is the most ideal state.

[0043] According to a further optimized solution, the plug 5 is disposed on a side of the insurance card 3 away from the hook 41 , and the bottom surface of the plug 5 is inclined.

[0044] With such a setting, the passage for the sling of the ton bag to enter the hook 41 can be cleared, preventing the edge of the bottom surface of the plug 5 from interfering with the entry of the ton bag sling into the hook 41.

[0045] In a further optimized solution, the end of the safety card 3 away from the hook 4 is the second counterweight arm 31, and the mass and distance between the second counterweight arm 31, the hook 4 and the plug 5 are matched, so that when the hook 4 is unloaded, the bottom surface of the plug 5 is horizontal.

[0046] The moments on both sides of the hinge point in the middle of the safety card 3 are set so that the bottom surface of the plug 5 can remain horizontal when unloaded. In this way, when the end of the safety card 3 hinged to the hook 4 is subjected to the gravity of heavy objects such as ton bags on the hook 41, the balance on both sides of the safety card 3 is broken, and the end of the safety card 3 close to the hook 41 rotates downward, causing the plug 5 to rotate towards the hook 41, and further enabling the plug 5 to be docked with the hook 41, blocking the opening of the hook 41 and realizing the anti - detachment function of the lifting tool.

[0047] In a further optimized solution, mounting plates 11 are fixedly connected to both sides of the beam body 1, and several safety cards 3 are evenly hinged to the mounting plates 11 on both sides.

[0048] The safety card 3 is hinged to the beam body 1 through the mounting plate 11. The mounting plates 11 are arranged on both sides of the beam body 1, with a symmetrical structure and further increasing the number of ton bags lifted at one time.

[0049] In a further optimized solution, the distance between two adjacent safety cards 3 is set according to the width of the ton bag.

[0050] The mounting spacing of the safety cards 3 on the mounting plates 11 determines the spacing when lifting ton bags. This spacing can be adjusted according to the width of the ton bag, thereby increasing the range of ton bags applicable to this lifting tool and broadening the applicability of this lifting tool.

[0051] In a further optimized solution, the safety card 3 and the mounting plate 11 are hinged through a third pin shaft 8 and a third locking nut 9, and the safety card 3 and the hook 4 are hinged through a second pin shaft 6 and a second locking nut 7.

[0052] The head of the third pin shaft 8 sequentially penetrates through the middle of the safety card 3 and the mounting plate 11, and the third locking nut 9 is threadedly connected to the head of the third pin shaft 8, thereby hinging the safety card 3 and the mounting plate 11;

[0053] The head of the second pin shaft 6 sequentially penetrates through the end of the safety card 3 and the middle of the hook 4, and the second locking nut 7 is threadedly connected to the head of the second pin shaft 6, thereby hinging the end of the safety card 3 and the hook 4.

[0054] In a further optimized solution, a number of mounting holes are provided on the mounting plate 11, and the third pin shaft 8 can be installed in any mounting hole and connected through the third locking nut 9.

[0055] It can be connected to the mounting holes at different positions on the mounting plate 11 through the third pin shaft 8 and the third locking nut 9 to adjust the distance between two adjacent safety cards 3, so as to adapt to different sizes of ton bags.

[0056] Usage process:

[0057] During specific hoisting, the lifting hook of the crane is hung on the lifting assembly 2. First, the entire lifting tool is lowered to a suitable position by the crane and moved towards the sling side of the ton bag until the sling at the top of the ton bag enters the hook 41, completing the automatic hooking operation, as Figure 5 shown; then the crane drives the whole to lift. At this time, the ton bag is hung in the hook 41, and the weight of the ton bag causes the hook 41 to rotate downward with the second pin shaft 6 as the axis, making the end of the safety card 3 with the plug 5 rotate downward with the third pin shaft 8 as the axis, so that the hook 41 and the plug 5 approach each other, making the plug 5 dock with the hook 41, blocking the opening of the hook 41, completing the hoisting of the ton bag and achieving the anti - detachment of the ton bag, as Figure 6 shown; move the whole lifting tool to move the ton bag to the designated position, lower the lifting tool, make the bottom of the ton bag abut against the ground, so as to unload the weight of the ton bag from the hook 41. The hook 41 rotates upward to the initial position under the weight of the first counterweight arm 42, and at the same time, the safety card 3 rotates upward under the weight of the second counterweight arm 31 to separate the plug 5 from the hook 41 and return to the initial position, completing the unloading operation, as Figure 7 shown; then move the lifting tool in the opposite direction to the hooking direction, and the sling of the ton bag can be removed from the hook 41, completing the automatic unhooking operation, as Figure 8 shown.

[0058] Embodiment 2

[0059] The difference between this embodiment and Embodiment 1 is only that the lifting assembly 2 is a vertical plate fixedly connected to the beam body 1, and a lifting hole is opened on the vertical plate. The lifting hook of the crane is directly hung in the lifting hole.
