Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting tool maintenance technology, and in particular to a separation protection mechanism and an anti-entanglement device. Background Technology
[0002] Heavy-duty lifting slings for bridge cranes are widely used in construction sites, warehouse logistics, rescue operations, and industrial production, primarily for lifting heavy or irregular workpieces. Traditional lifting slings typically consist of lifting rings, chains, clips, and hooks. Multiple chains are secured to the lifting rings via spiral clips, allowing the hook to hang naturally to distribute the load. However, with the expansion of project scale and the increasing complexity of operating environments, traditional lifting slings have revealed structural defects over long-term use, affecting safety and efficiency. Multiple clips collide and rub against each other during lifting or when idle, causing structural damage and shortening service life. The freely hanging chains are prone to tangling during movement or stacking, increasing untangling time, reducing work efficiency, and potentially leading to operational errors, personal injury, or equipment damage.
[0003] Therefore, there is a need for a separation and protection mechanism and anti-entanglement device that can isolate the buckles in pairs, provide a buffer structure to reduce collision wear, extend service life, facilitate disassembly, effectively prevent chain entanglement, and improve operational efficiency to meet the needs of the current construction environment. Utility Model Content
[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0005] Given that traditional lifting tools suffer from structural damage and shortened service life due to mutual collisions and friction in long-term use environments.

[0040] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0041] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0042] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0043] Secondly, this utility model is described in detail with reference to the schematic diagrams.

[0044] Example 1
[0045] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a separation and protection mechanism.
[0046] The positioning assembly 1 is integrally mounted on the large hanging ring of the lifting device, facilitating the positioning and separation of multiple hooks. The hanging plate 11 is a ring-shaped or split metal component, fitted onto the outer edge of the large hanging ring, with the large hanging ring passing through the center of the hanging plate 11. The separation frame 12 is fixedly connected to the hanging plate 11, therefore the hanging plate 11 can also serve as a support base for the separation frame 12. The hanging plate 11 needs to withstand the dynamic load during lifting, therefore low-alloy steel is used to balance strength and fatigue resistance.
[0047] The separation frame 12 is composed of several radially distributed partitions. The spacing between the partitions is designed to be equal according to the number of hooks actually used. The thickness of the partitions of the separation frame 12 can be 10-15mm and the edges are rounded to avoid stress concentration.
[0048] A through slot 13 is provided in the middle of the hanging plate 11. The through slot 13 itself is a through hole in the middle of the hanging plate 11, and the diameter of the hole is adapted to the cross-sectional dimensions of the large hanging ring, allowing the large hanging ring to pass through and rotate appropriately to adjust the angle. The through slot 13 can ensure that the relative position of the large hanging ring and the hanging plate 11 is adjustable, so as to meet the center of gravity balance requirements under different lifting conditions.
[0049] The auxiliary component 2 mainly provides buffer protection for the separation protection mechanism. The buffer component 21 is set in the through slot 13 in the center of the hanging plate 11. When the lifting device is subjected to impact load (such as sudden lifting), the buffer component 21 absorbs energy through elastic deformation, reduces the vibration transmitted to the large hanging ring and hook, and plays a protective role.
[0050] A docking screw 22 is slidably installed at the bottom of the mounting plate 11. The bottom of the docking screw 22 is provided with a threaded joint to facilitate connection and matching with the branch structure. The upper part of the docking screw 22 is located in the internal cavity of the mounting plate 11, which can be slidably engaged and disassembled.
[0051] Example 2
[0052] Reference Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:
[0053] Two limiting protrusions 131 are fixedly installed on the upper part of the inner wall of the through slot 13. The limiting protrusions 131 can cooperate with the buffer 21. One end of the buffer 21 includes a closing top block 211. The closing top block 211 is designed in an I-shape to effectively fit the structure of the through slot 13 and the limiting protrusions 131. The closing top block 211 slides on the limiting protrusions 131, which is convenient for disassembly and removal.
[0054] On the side wall of the through slot 13, below the limiting protrusion 131, two sliding slots 132 are provided. A separation slot 133 extends vertically from the upper end of the sliding slot 132. An adapting support plate 212 is slidably disposed within the sliding slot 132. Both ends of the adapting support plate 212 can move up and down along the sliding slot 132. The adapting support plate 212 is the other end of the buffer member 21.
[0055] An elastic element 2121 is fixedly connected to the top of the adapting tray 212. The elastic element 2121 can be a spring or an elastic telescopic rod with a structure that can be compressed and reset elastically. The other end of the elastic element 2121 is fixedly connected to the closing top block 211, forming a complete buffer element 21 structure. The buffer element 21 is easy to disassemble. When it needs to be removed, simply push the adapting tray 212 upwards, and then move the adapting tray 212 in a straight line along the separation groove 133, removing it together with the closing top block 211.
[0056] A matching slot 121 is fixedly opened on the side wall of the separation frame 12. The matching slot 121 can be appropriately matched with the size of the through slot 13 to ensure that large hanging rings can be inserted while effectively separating the hooks. A hollow slot 122 is fixedly opened on the top of the separation frame 12. The layout of the hollow slot 122 is to close the two sides of the top block 211, thus forming an effective "handle"-like structure, which is convenient for workers to operate and pull to install or disassemble.
[0057] The mounting plate 11 has an internal cavity 14, and the bottom of the cavity 14 has a connecting hole 141 for fitting with the docking screw 22. The side wall of the docking screw 22 has a straight protrusion that cooperates with the connecting hole 141, thereby ensuring that the docking screw 22 has a stable linear motion function. Except for the threaded part at the bottom, the docking screw 22 can move linearly along the connecting hole 141. A limiting plate 221 is fixedly installed on the top of the docking screw 22. The diameter of the limiting plate 221 is larger than the diameter of the connecting hole 141, controlling the linear motion range of the docking screw 22 within the required range.
[0058] On one side of the connecting hole 141, at the bottom of the accommodating cavity 14, a limiting hole 1411 is fixedly provided. The limiting hole 1411 can cooperate with the limiting bolt 2211 fixedly connected to one side of the limiting plate 221. In the default state, when the hanging plate 11 is put into use, under the action of gravity and the large hanging ring, the top limiting plate 221 of the docking screw 22 will always maintain a certain distance from the connecting hole 141. When it is necessary to disassemble the entire separation protection mechanism, simply lower the entire set of lifting tools, and the operator pulls up the hanging plate 11 to ensure that the docking screw 22 moves to its limit position, and the limiting bolt 2211 on the limiting plate 221 inserts into the limiting hole 1411.
[0059] At this point, the operator can directly rotate the upper structure of the mounting plate 11 to directly rotate the connecting screw 22, thereby disassembling and separating it from the connected control component 3. The setting of the limiting hole 1411 is to ensure the stable movement of the connecting screw 22. Even if the side wall of the connecting screw 22 is not provided with a protrusion to cooperate with the connecting hole 141, and the simplest plug-in form is used, it can still ensure that the connecting screw 22 rotates stably in subsequent work.
[0060] Example 3
[0061] Reference Figures 1-3 This is the third embodiment of the present invention, which adds an anti-winding device based on the above embodiments.
[0062] The anti-tangling component 3 is mainly used for preventing chain entanglement in heavy-duty bridge crane spreaders. Its core function is to control the free swing range of the chain and prevent multiple chains from tangling together. The mating base 31 is a cylindrical or square metal block with a through hole in the center. It can be rotated to connect with the docking screw 22 via bearings or bushings, allowing the mating base 31 to rotate 360° relative to the chain. The mating base 31 can be made of steel with high impact resistance and wear resistance.
[0063] Multiple slots 32 are fixedly opened on the side wall of the base 31. The spacing of the slots 32 is fixed, and the number of slots can be matched according to the number of hooks. The slots 32 are U-shaped or V-shaped grooves with a width slightly larger than the chain diameter. The inner surface of the slot is polished or inlaid with nylon pads to reduce chain friction and wear. Each chain corresponds to one slot 32, and physical separation prevents adjacent chains from contacting and tangling.
[0064] The extension sleeve 321 is welded or bolted to one side of the partition groove 32 and has internal threads. The telescopic stop rod 3211 is a screw structure that mates with the threaded inner wall of the extension sleeve 321. An adjustment end 3212 is welded to the end of the telescopic stop rod 3211. The diameter of the adjustment end 3212 is larger than that of the telescopic stop rod 3211 and the outer wall is adapted to have grooves or protrusions for easy operation by the staff.
[0065] Rotate the adjusting end 3212 to push the telescopic stop bar 3211 to move axially and change its extension length. After the telescopic stop bar 3211 extends, it abuts against the end of the chain to limit its swing amplitude and prevent entanglement. When the entire process is completed and the anti-entanglement device needs to be disassembled and maintained, the adjusting end 3212 can be rotated in the opposite direction again to move the chain out of the partition groove 32 before proceeding with the subsequent disassembly work.
