Description

Technical Field

[0001] The utility model belongs to the technical field of sling equipment, in particular to a quick hanging device. Background Art

[0002] A lifting tool is a material handling tool used to lift or hoist heavy objects. It operates intermittently, lifting heavy objects. Most lifting tools begin a vertical or combined vertical and horizontal travel after retrieving material. Upon reaching the destination, they unload the material and then travel back to the retrieving location, completing a cycle before performing a second lift. Generally speaking, when a lifting tool is operating, retrieving, transporting, and unloading materials occur sequentially, with each mechanism operating intermittently.

[0003] Lifting equipment plays a crucial role in lifting devices. Lifting equipment refers to the device used to lift heavy objects in cranes. Commonly used lifting equipment include specialized rigging such as hooks, wire ropes, and chains. Suction cups, clamps, and forks can be used as dedicated lifting equipment on cranes for long-term use, or as interchangeable auxiliary lifting equipment hung on hooks for temporary use. They are often used in warehouses and yards handling a wide variety of goods to improve operational efficiency. However, for items that only have internal holes as lifting locations, this can cause surface scratches and other defects, suggesting that there is still room for improvement in lifting equipment. Utility Model Content

[0004] In view of this, the utility model provides a quick hanging device which can improve the lifting effect to meet industrial needs.

[0005] A quick-hanging device includes a lifting rod, multiple lifting assemblies movably connected to the lifting rod, and a release mechanism mounted on the lifting rod and connected to one end of the lifting assemblies. The lifting rod includes a lifting rod body. The lifting assembly includes multiple lifting supports disposed around the outside of the lifting rod body, and multiple hinged frames hinged between the lifting rod body and the lifting supports. The release mechanism includes a release body mounted on the lifting rod body, and a connecting unit mounted between the release body and the lifting assembly. The release body includes a release sleeve mounted on the lifting rod body, and two rings symmetrically mounted on the release sleeve. The connecting unit includes a connecting sleeve mounted on the lifting rod body, multiple first connecting rods hingedly connected to the connecting sleeve and the release sleeve, and multiple second connecting rods hingedly connected between the connecting sleeve and the lifting assembly. Each second connecting rod is connected to one end of a lifting support to drive the lifting support.

[0006] Furthermore, the lifting rod also includes a lifting ring arranged at one end of the lifting rod body.

[0007] Furthermore, the quick hanging device also includes a limiting mechanism arranged between the lifting assembly and the releasing mechanism.

[0008] Furthermore, the limiting mechanism includes a fixing seat fixedly connected to the lifting rod, a plurality of limiting frames fixedly connected to the fixing seat, and a positioning ring fixedly connected to the limiting frame, and the fixing seat is arranged between the release sleeve and the connecting sleeve.

[0009] Furthermore, each of the limiting frames is arranged along the radial direction of the positioning ring, and the length of the limiting frame is greater than the outer diameter of the positioning ring.

[0010] Furthermore, the end surface of the outer side wall of the lifting support is inclined.

[0011] Furthermore, two articulated frames are provided between each lifting support and the boom body.

[0012] Compared to the prior art, the quick-hanging device provided by the present invention utilizes a release mechanism to control the sliding movement of the lifting assembly along the lifting rod, thereby lifting a workpiece. The articulated frame in the lifting assembly is hinged between the lifting rod body and the lifting support, thereby achieving a movable connection between the lifting supports. The release mechanism comprises a release body disposed on the lifting rod body and a connecting unit that fits between the release body and the lifting assembly. A release sleeve in the release body fits over the lifting rod body, and the release sleeve is provided with a circular ring. A connecting sleeve in the connecting unit fits over the lifting rod body. The connecting sleeve and the release sleeve are hinged to a first connecting rod. Multiple hinged sleeves, hinged between the connecting sleeve and the lifting assembly, are hinged to a second connecting rod, thereby connecting the release body and the lifting assembly. When the quick-hanging device is lifting a workpiece, the release body, under the action of its own gravity, pushes the connecting unit and the lifting support outward, bringing them into contact with the workpiece hole wall. When the workpiece is transferred, simply lift the ring of the release body upwards, and the lifting support will retract inward, allowing the entire quick-hanging device to be lifted and removed. This demonstrates that the quick-hanging device can lift workpieces through inner holes, reducing assembly and disassembly time and effectively preventing scratches and other defects on the workpiece surface.

[0015] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0016] like Figures 1 to 2 FIG2 is a schematic diagram of the structure of the quick hanging device provided by the present invention. The quick hanging device includes a lifting rod 10, a plurality of lifting assemblies 20 movably connected to the lifting rod 10, a release mechanism 30 sleeved on the lifting rod 10 and connected to one end of the lifting assemblies 20, and a limiting mechanism 40 disposed between the lifting assembly 20 and the release mechanism 30. The quick hanging device also includes other functional modules, such as assembly components, which are well known to those skilled in the art and will not be described in detail here.

[0017] The lifting rod 10 includes a lifting rod body 11 and a lifting ring 12 provided at one end of the lifting rod body 11 .

[0018] The lifting rod body 11 is used to install the lifting assembly 20 and the release mechanism 30. The lifting rod body 11 forms the lifting assembly 20 and the release mechanism 30 into a whole. The lifting rod body 11 is an existing technology and will not be described in detail here.

[0019] The lifting ring 12 is fixedly connected to the lifting rod body 11. The lifting ring 12 is used for lifting equipment (not shown). The lifting ring 12 is a prior art and will not be described in detail here.

[0020] The lifting assembly 20 includes a plurality of lifting supports 21 disposed around the outside of the lifting rod body 11 , and a plurality of articulated frames 22 hinged between the lifting rod body 11 and the lifting supports 21 .

[0021] Each of the articulated frames 22 is connected to a lifting support member 21, enabling the lifting support member 21 to move outside the lifting rod body 11, that is, the lifting support member 21 can move toward or away from the lifting rod body 11. The articulated structures between the articulated frames 22, the lifting support members 21, and the lifting rod body 11 are all prior art and will not be described in detail here. In this embodiment, two articulated frames 22 are provided between each lifting support member 21 and the lifting rod body 11 to stabilize the position of the lifting support member 21 on the lifting rod body 11.

[0022] In addition, the outer wall end surfaces of the lifting supports 21 are inclined, so that when multiple lifting supports 21 are gathered together, they form a tapered structure, which facilitates the rapid removal of the lifting supports 21 from the workpiece when the workpiece transfer is completed. The hinged structure between the hinge frame 22, the lifting supports 21, and the lifting rod body 11 is a prior art and will not be described in detail here.

[0023] The release mechanism 30 includes a release body 31 disposed on the lifting rod body 11 and a connection unit 32 sleeved between the release body 31 and the lifting assembly 20 .

[0024] The release body 31 includes a release sleeve 311 that is sleeved on the lifting rod body 11, and two rings 312 symmetrically disposed on the release sleeve 311. The release body 31 can drive the connection unit 32 downward by its own weight, and the user can slide the connection unit 32 via the rings 312. The release sleeve 311 and the rings 312 are both conventional and will not be described in detail here.

[0025] The connecting unit 32 includes a connecting sleeve 321 sleeved on the lifting rod body 11, a plurality of first connecting rods 322 hingedly connected to the connecting sleeve 321 and the release sleeve 311, and a plurality of second connecting rods 323 hingedly connected between the connecting sleeve and the lifting assembly 20.

[0026] The connecting sleeve 321 can slide along the lifting rod body 11 to achieve lifting and lowering on the lifting rod body 11. The first connecting rod 322 and the second connecting rod 323 connect the connecting sleeve 321 with the release body 31 and the lifting assembly 20. The connecting sleeve 321, the first connecting rod 322, and the second connecting rod 323 are all existing technologies.

[0027] The first connecting rod 322 connects the connecting sleeve 321 and the release sleeve 311 together. The connection structure between the first connecting rod 322, the connecting sleeve 321, and the release sleeve 311 is a prior art.

[0028] The second connecting rod 323 connects the connecting sleeve 321 and the lifting assembly 20 together. Each second connecting rod 323 is connected to one end of the lifting support 21 to drive the lifting support 21 to move. The hinged structure between the second connecting rod 323 and the connecting sleeve 321 and the lifting assembly 20 is an existing technology and will not be repeated here.

[0029] The limiting mechanism 40 includes a fixing seat 41 fixedly connected to the lifting rod 10 , a plurality of limiting frames 42 fixedly connected to the fixing seat 41 , and a positioning ring 43 fixedly connected to the limiting frames 42 .

[0030] The fixing seat is arranged between the release sleeve 311 and the connecting sleeve 321, thereby limiting the movable position of the release body 31 and the connecting unit 32. The fixing structure between the fixing seat 41 and the lifting rod 10 is an existing technology and will not be repeated here.

[0031] The length of the limiting frame 42 is greater than the outer diameter of the positioning ring 43, so that the limiting frame 42 and the positioning ring 43 form a double limit to improve the effect of the limiting mechanism 40. The limiting frame 42 and the positioning ring 43 are both existing technologies and will not be described in detail here.

[0032] When the quick hanging device is used to lift a workpiece, it is placed in a workpiece hole (not shown). The limiting frame 42 and the positioning ring 43 limit the lifting device, so that the quick hanging device is fixed in the hole. At this time, due to the weight of the release body 31, the release body 31 pushes the connecting unit 32 and the lifting support 21 to expand outward and contact the wall of the workpiece hole. At this time, by pulling the lifting ring 12 in the lifting rod 10 upward, the lifting support 21 is exerted with an outward force, which increases the friction between the lifting support 21 and the hole wall, thereby lifting the workpiece for transportation. When the workpiece is transported, it is only necessary to lift the ring 312 of the release body 31 upward, and the lifting support 21 will retract inward, so that the entire quick hanging device can be lifted and removed.

[0033] Compared with the prior art, the quick hanging device provided by the present invention controls the lifting assembly 20 to slide along the lifting rod 10 through the release mechanism 30 to achieve the lifting of the workpiece. The articulated frame 22 in the lifting assembly 20 is hinged between the lifting rod body 11 and the lifting support 21, thereby achieving a movable connection between the lifting support 21. The release mechanism 30 includes a release body 31 disposed on the lifting rod body 11 and a connecting unit 32 sleeved between the release body 31 and the lifting assembly 20. The release sleeve 311 in the release body 31 is sleeved on the lifting rod body 11, and the release sleeve 311 is provided with a ring 312. The connecting sleeve 321 in the connecting unit 32 is sleeved on the lifting rod body 11, and the connecting sleeve 321 and the release sleeve 311 are hinged to the first connecting rod 322, and multiple hinges are hinged between the connecting sleeve and the lifting assembly 20 and are hinged to the second connecting rod 323, so that the release body 31 and the lifting assembly 20 are connected together. When the quick hanging device lifts the workpiece, the release body 31 is affected by its own gravity, and the release body 31 pushes the connecting unit 32 and the lifting support 21 to expand outward and contact the wall of the workpiece hole. When the workpiece is transported, it is only necessary to lift the ring 312 of the release body 31 upwards, and the lifting support 21 can be retracted inward, and the entire quick hanging device can be lifted and removed. It can be seen from this that the quick hanging device meets the requirements of lifting the workpiece through the inner hole, reducing the time for disassembling and assembling the sling, and can effectively avoid defects such as scratches on the workpiece surface.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
