Description

Technical Field

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

[0002] Lifting tools are material handling tools for lifting or lifting heavy objects, and are tools that work intermittently and lift heavy objects. Most lifting tools start a vertical or vertical and horizontal working stroke after the spreader picks up the material, unload after reaching the destination, and then travel to the material picking location without moving, completing a working cycle, and then carry out the second lifting. Generally speaking, when the lifting tool is working, picking up materials, moving and unloading are carried out in sequence, and the work of each corresponding mechanism is intermittent.

[0003] In the lifting device, the sling plays a vital role. The sling refers to the device used in the lifting machinery to lift heavy objects. The slings are commonly used in special rigging such as hooks, wire ropes, chains, etc. Lifting suction cups, clamps and forks can be used as special slings on cranes for a long time, or as replaceable auxiliary slings hung on the hook for temporary use. They are often used in warehouses and yards with multiple types of goods to improve work efficiency. However, for items with only inner holes as lifting positions, defects such as scratches will be caused on the surface of the workpiece during the lifting process. There is still room for improvement in slings. Summary of the invention

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

[0005] A quick hanging device includes a lifting rod, a plurality of lifting components movably connected to the lifting rod, and a release mechanism sleeved on the lifting rod and connected to one end of the lifting component. The lifting rod includes a lifting rod body. The lifting component includes a plurality of lifting supports arranged around the outside of the lifting rod body, and a plurality of hinged frames hinged between the lifting rod body and the lifting support. The release mechanism includes a release body arranged on the lifting rod body, and a connecting unit sleeved between the release body and the lifting component. The release body includes a release sleeve sleeved on the lifting rod body, and two rings symmetrically arranged on the release sleeve. The connecting unit includes a connecting sleeve sleeved on the lifting rod body, a plurality of first connecting rods hinged on the connecting sleeve and the release sleeve, and a plurality of second connecting rods hinged between the connecting sleeve and the lifting component. Each second connecting rod is connected to one end of a lifting support to drive the lifting support to move.

[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 arranged between each of the lifting supports and the boom body.

[0012] Compared with the prior art, the quick hanging device provided by the present invention controls the lifting assembly to slide along the lifting rod through the release mechanism to realize the lifting of the workpiece. The articulated frame in the lifting assembly is hinged between the lifting rod body and the lifting support, so as to realize the movable connection between the lifting support. The release mechanism includes a release body arranged on the lifting rod body and a connecting unit sleeved between the release body and the lifting assembly. The release sleeve in the release body is sleeved on the lifting rod body, and the release sleeve is provided with a ring. The connecting sleeve in the connecting unit is sleeved on the lifting rod body, and the connecting sleeve and the release sleeve are hinged on the first connecting rod, and a plurality of hinged sleeves are hinged between the connecting sleeve and the lifting assembly and are hinged on the second connecting rod, so that the release body and the lifting assembly are connected together. When the quick hanging device lifts the workpiece, the release body is acted on by its own gravity, and the release body pushes the connecting unit and the lifting support to expand outward and contact the hole wall of the workpiece. When the workpiece transfer is completed, the ring of the release body only needs to be lifted upwards, and the lifting support can be retracted inwards, 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 lifting device, and can effectively avoid scratches and other defects on the workpiece surface.

[0015] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0016] like Figure 1 to Figure 2 As shown, it 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 components 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 component 20, and a limit mechanism 40 arranged between the lifting component 20 and the release mechanism 30. The quick hanging device also includes some other functional modules, such as assembly components, etc., which should be well known to those skilled in the art and will not be described in detail one by one here.

[0017] The lifting rod 10 includes a lifting rod body 11 and a lifting ring 12 arranged 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 a prior art and will not be described in detail herein.

[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 21, so that the lifting support 21 can move outside the lifting rod body 11, that is, the lifting support 21 can gather or move away from the lifting rod body 11. The articulated structures between the articulated frames 22, the lifting support 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 of the lifting support 21 and the lifting rod body 11, so that the position of the lifting support 21 on the lifting rod body 11 is stable.

[0022] In addition, the end surface of the outer wall of the lifting support 21 is inclined, so that when the multiple lifting support 21 are gathered together, the multiple lifting support 21 form a conical structure, so that when the workpiece is transported, the lifting support 21 can be quickly removed from the workpiece. The hinged structure between the hinge frame 22 and the lifting support 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 sleeved on the lifting rod body 11, and two rings 312 symmetrically arranged on the release sleeve 311. The release body 31 can drive the connection unit 32 to descend by pressing down under its own weight, and the user can drive the connection unit 32 to slide through the ring 312. The release sleeve 311 and the ring 312 are both existing technologies 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 releasing sleeve 311 together. The connecting structure between the first connecting rod 322, the connecting sleeve 321, and the releasing sleeve 311 is a prior art.

[0028] The second connecting rod 323 connects the connecting sleeve 321 and the lifting assembly 20 together. Each of the second connecting rods 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 a prior art 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, so as to limit 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 a prior art and will not be described 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, the quick hanging device is placed in the workpiece hole (not shown), and the limit frame 42 and the positioning ring 43 are used to limit the lifting device, so that the quick hanging device is fixed in the hole. At this time, due to the effect of the release body 31's own gravity, the release body 31 pushes the connection 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, an outward force is applied to the lifting support 21, so that the friction between the lifting support 21 and the hole wall is increased, so that the workpiece can be lifted for transportation. When the workpiece transportation is completed, it is only necessary to lift the ring 312 of the release body 31 upward, and the lifting support 21 can shrink 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 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, so as to achieve 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 connection 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 upward, and the lifting support 21 can shrink 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 needs 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 surface of the workpiece.
