Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of lifting slings, and more specifically, to a lifting sling with anti-slip function. Background Technology
[0002] Rigging refers to equipment used with ropes and cables, such as hooks, tensioners, clamps, swivels, and shackles. While some classifications include ropes and cables, rigging is also sometimes used. Rigging is mainly divided into two categories: metal rigging and synthetic fiber rigging. The term also encompasses all masts, girder (horizontal mast), sail bar (sail mast), diagonal girder, and all cables, chains, and the tools used to operate them. In the use of rigging, the tightness of rigging connections is particularly important. The following problems still exist in the current use of rigging:
[0003] In hoisting operations, hoisting slings are used to pull objects, so the safety of hoisting slings is particularly important. Existing open-type hoisting slings rely on the weight of the object itself to increase the stability of the connection. When the object is light, it may sway significantly during transportation, which could lead to the object coming off the hook and pose a significant safety hazard.
[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content
[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a lifting sling with anti-slip function, which solves the technical problem that existing open-type lifting slings rely on the weight of the object itself to increase the stability of the connection, but during transportation, the object shakes significantly and there is a phenomenon of disengagement.
[0006] According to one aspect, at least one embodiment of this disclosure provides a lifting sling with anti-slip function, comprising:
[0007] The main shaft, the hanger, and the lifting ring are provided, wherein the main shaft is disposed within the hanger and the lifting ring is rotatably connected within the hanger.
[0008] A fixing component is disposed between the main shaft and the hanger;
[0009] A hook and a locking connection assembly, wherein the hook is disposed on the main shaft and the locking connection assembly is disposed between the hook and the main shaft;
[0010] The locking connection assembly includes a pair of bushings, both of which are rotatably connected to the main shaft. The hook is fixed to the bottom of the pair of bushings, and a limit port is opened at the outer end of the hook. An anti-detachment bracket is rotatably connected to the main shaft.
[0011] As a further technical solution, a pair of limiting rings are fixed on the main shaft, the limiting rings slide against both sides of the anti-detachment frame, a hanging bracket is provided on the side surface of the limiting frame, and a pair of round rods are fixedly connected to the inner end face of the hanging bracket.
[0012] As a further technical solution, each of the round rods is fitted with a spring, and a movable frame is movably connected to the round rod. The upper end face of the movable frame is provided with an insert block, and the side end face of the movable frame extends outward beyond the hook.
[0013] As a further technical solution, the fixing component includes a pair of mounting slots, which are formed on both sides of the hanger. The main shaft is inserted into the mounting slots, and a clamping bracket is inserted into each mounting slot.
[0014] As a further technical solution, a rotating groove is provided at the bottom of the mounting groove and at the lower end face of the clamping frame, a pair of threaded grooves are provided on the side end face of the mounting groove, and a pair of circular grooves are provided on the side end face of the clamping frame.
[0015] As a further technical solution, a fixing bolt is inserted into the circular groove, and one end of the fixing bolt is screwed into the threaded groove.
[0016] As a further technical solution, the lower end of the anti-slip frame has an arc-shaped transition structure, and the width of the anti-slip frame is smaller than the inner opening size of the limit buckle.
[0017] As a further technical solution, the upper end of the hook has a Y-shaped structure.
[0018] As a further technical solution, the thickness of the insert block is matched with the size of the bracket opening.
[0019] As a further technical solution, both ends of the main shaft have outward protrusions on their circumference, and the protruding portions at both ends of the main shaft are slidably connected within the rotating groove.
[0020] The beneficial effects of the embodiments disclosed herein are as follows:
[0021] 1. The beneficial effects of the locking connection assembly in this disclosure are that the bushing allows the hook to rotate flexibly to facilitate hooking goods, the limit port and the anti-detachment frame work together to effectively prevent goods from detaching and improve the safety of hoisting, the limit ring accurately limits the anti-detachment frame to ensure that it corresponds accurately with the limit port, and the design of the movable frame, the insert block and the spring uses elasticity to fix the anti-detachment frame, which is simple to operate and highly reliable, reducing the risk of detachment due to shaking.
[0022] 2. In this disclosure, the beneficial effect of the fixing component is that the mounting groove provides an installation position for the main shaft, and the combination of the clamping frame and the fixing bolts firmly fixes the main shaft in the hanger. The rotating groove ensures the connection stability of the main shaft without affecting its rotation. This structural design enhances the overall stability of the rigging, avoids loosening of the main shaft and the hanger during hoisting, and ensures the safe operation of hoisting.

[0035] like Figures 1-4 As shown, a lifting sling with anti-slip function is illustrated in one embodiment of this disclosure, comprising:
[0036] The main shaft 1, the hanger 2, and the lifting ring 3 are provided. The main shaft 1 is installed inside the hanger 2, and the lifting ring 3 is rotatably connected inside the hanger 2.
[0037] Fixing component 6 is disposed between the main shaft 1 and the hanger 2;
[0038] Hook 4 and locking connection assembly 5, hook 4 is set on main shaft 1, and locking connection assembly 5 is set between hook 4 and main shaft 1;
[0039] The locking connection assembly 5 includes a pair of bushings 5-1, both of which are rotatably connected to the main shaft 1. Hooks 4 are fixed to the bottom of the pair of bushings 5-1. Limiting holes 5-2 are opened at the outer ends of hooks 4. Anti-detachment brackets 5-3 are rotatably connected to the main shaft 1. A pair of limiting rings 5-4 are fixed to the main shaft 1. The limiting rings 5-4 slide against both sides of the anti-detachment brackets 5-3. Hangers 5-5 are provided on the side surface of the limiting brackets. A pair of round rods 5-6 are fixedly connected to the inner end face of the hanger 2. Springs 5-7 are installed on each of the round rods 5-6. Movable frames 5-8 are movably connected to the round rods 5-6. Insert blocks 5-9 are provided on the upper end face of the movable frames 5-8. The side end face of the movable frames 5-8 extends outward beyond the hooks 4.
[0040] In some examples, to achieve the effect of locking and preventing detachment when the hook 4 lifts goods, a locking connection assembly 5 is designed. This assembly includes a pair of bushings 5-1, both rotatably connected to the main shaft 1. The hook 4 is fixed to the bottom of the pair of bushings 5-1, allowing the hook 4 to rotate around the main shaft 1 for easy operation to hook and lift goods. A limiting port 5-2 is opened at the outer end of the hook 4, and an anti-detachment frame 5-3 is rotatably connected to the main shaft 1. The anti-detachment frame 5-3 can enter the limiting port 5-2 to lock the hook 4, preventing the goods from falling off. A pair of limiting rings 5-4 are fixed on the main shaft 1, slidingly fitting against both sides of the anti-detachment frame 5-3, which can limit the position of the anti-detachment frame 5-3 and ensure the anti-detachment frame 5-3. -3 can maintain correspondence with the limiting port 5-2. The hanging bracket 5-5 is provided on the side surface of the anti-detachment bracket 5-3, and a pair of round rods 5-6 are fixedly connected to the inner end face of the hanger 2. A movable frame 5-8 is slidably mounted on the outside of the rods. The movable frame 5-8 can move vertically up and down on the round rods 5-6. A spring 5-7 is mounted on the round rods 5-6. The movable frame 5-8 has a certain elasticity, which keeps the movable frame 5-8 with an upward force. The insert block 5-9 provided on the upper end face of the movable frame 5-8 can be inserted into the limiting port 5-2 at the outer end of the hook 4 during hoisting. The insert block 5-9 can be pushed into the hanging bracket 5-5 by the elastic force of the spring 5-7, so that the anti-detachment bracket 5-3 is fixed and the hook 4 is locked to prevent it from opening accidentally.
[0041] like Figures 1-4 As shown, this embodiment proposes a fixing component 6 including a pair of mounting slots 6-1, which are opened on both sides of the hanger 2. The main shaft 1 is inserted into the mounting slot 6-1, and a clamping bracket 6-2 is inserted into each mounting slot 6-1. A rotating slot 6-3 is opened at the bottom of the mounting slot 6-1 and at the lower end face of the clamping bracket 6-2. A pair of threaded slots 6-4 are opened on the side end face of the mounting slot 6-1, and a pair of circular slots 6-5 are opened on the side end face of the clamping bracket 6-2. A fixing bolt 6-6 is inserted into the circular slot 6-5, and one end of the fixing bolt 6-6 is screwed into the threaded slot 6-4.
[0042] In some examples, to achieve a stable connection between the spindle 1 and the hanger 2, a fixing assembly 6 is designed. This assembly includes a pair of mounting slots 6-1, which are located on both sides of the hanger 2. The spindle 1 is inserted into the mounting slots 6-1, and a clamping bracket 6-2 is inserted into each mounting slot 6-1. Rotation slots 6-3 are formed at the bottom of the mounting slots 6-1 and on the lower end face of the clamping bracket 6-2, which securely fix the spindle 1 within the mounting slots 6-1 without affecting its position. As the main spindle 1 rotates, a pair of threaded grooves 6-4 are provided on the side end face of the mounting groove 6-1, and a pair of circular grooves 6-5 are provided on the side end face of the clamping frame 6-2. The circular grooves 6-5 and the threaded grooves 6-4 are positioned opposite each other. When one end of the fixing bolt 6-6 inserted in the circular groove 6-5 is screwed into the threaded groove 6-4, the clamping frame 6-2 can be firmly fixed in the mounting groove 6-1 by tightening the fixing bolt 6-6, thereby realizing a firm connection between the main spindle 1 and the hanger 2.
[0043] For example, such as Figure 3 As shown, the lower end of the anti-slip bracket 5-3 has an arc-shaped transition structure, and the width of the anti-slip bracket 5-3 is smaller than the inner opening size of the limit buckle.
[0044] In some examples, the curved transition structure allows the anti-detachment frame 5-3 to match the curvature of the hook without affecting the lifted goods.
[0045] For example, such as Figure 3 As shown, the upper end of hook 4 has a Y-shaped structure.
[0046] In some examples, the Y-shaped structure increases the strength of hook 4, making it more capable of bearing weight.
[0047] For example, such as Figure 2 As shown, the thickness of the insert 5-9 matches the opening size of the bracket 5-5.
[0048] In some examples, by matching the dimensions, the insert 5-9 will not wobble after being inserted into the bracket 5-5, thus reducing wear.
[0049] For example, such as Figure 3 As shown, both ends of the main spindle 1 have outward protrusions on their circumference, and the protruding parts at both ends of the main spindle 1 are slidably connected in the rotating groove 6-3.
[0050] In some examples, the connection strength of the main shaft 1 can be improved by the outward protrusion and the engagement with the rotating groove 6-3, and there will be no situation of falling off.
[0051] In actual use: Insert the main shaft 1 into the mounting slots 6-1 on both sides of the hanger 2, insert the clamping frame 6-2 into the mounting slot 6-1, and tighten it with the fixing bolts 6-6 to make the main shaft 1 and the hanger 2 securely connected. Rotate the hook 4 to hook the goods, rotate the anti-detachment frame 5-3 to make it enter the limiting port 5-2 of the hook 4, push the movable frame 5-8 to let the insert block 5-9 insert into the hanger 5-5, use the spring 5-7 to fix the anti-detachment frame 5-3, and close the hook 4 to prevent the goods from falling off. Connect the rigging to the lifting equipment through the lifting ring 3 for lifting. After the lifting is completed, reverse the operation of the movable frame 5-8 and the anti-detachment frame 5-3 to remove the goods.
[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
