Description

Technical Field

[0001] This utility model belongs to the field of hoisting sling technology, and specifically relates to a fixing structure for hoisting slings. Background Technology

[0002] As an indispensable connecting tool in lifting operations, lifting slings securely connect lifting machinery to the object being lifted, enabling the safe transfer of heavy objects. Their core functions encompass three major aspects: fixing, lifting, and handling, playing a fundamental supporting role in the material flow systems of industries such as construction, machinery manufacturing, and transportation.

[0003] For example, Chinese Patent No. CN208218185U discloses a reinforced lifting sling, including a first stainless steel lifting ring, a second stainless steel lifting ring, a hanging ring rotatably connected to the top of the first and second stainless steel lifting rings, a first wire rope and a second wire rope connected to the first stainless steel lifting ring, a third wire rope and a fourth wire rope connected to the second stainless steel lifting ring, a first hook at the bottom of the first wire rope, a second hook at the bottom of the second wire rope, a third hook at the bottom of the third wire rope, and a fourth hook at the bottom of the fourth wire rope.

[0004] Although the aforementioned patent achieves the purpose of lifting goods, the hook is fixed to the wire rope and cannot be disassembled. When the hook needs to be replaced due to wear, deformation or special working conditions, the entire wire rope must be replaced, resulting in material waste. Furthermore, when the goods are suspended on the hook by the rope, the rope is very likely to slip off from the hook opening under vibration, shaking or sudden impact during the lifting process, leading to a cargo falling accident. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a fixing structure for lifting slings to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A fixing structure for lifting slings includes a chain, a force sensor on one side of the chain, a fixing base fixedly connected to the bottom end of the force sensor, connecting grooves on both sides of the bottom end of the fixing base, connecting blocks inserted into the connecting grooves, mounting bases fixedly connected to the bottom ends of the connecting blocks, hooks fixedly connected to the bottom ends of the mounting bases, a limiting component on one side of the fixing base, a positioning component on one side of the fixing base, and a locking component on one side of the positioning component.

[0008] As a preferred technical solution, a locking ring is fixedly connected to the top of the force sensor, and the locking ring is connected to the lower side of the chain.

[0009] As a preferred technical solution, the limiting component includes a micro motor, which is fixedly connected to one side of the fixed base. The output end of the micro motor is fixedly connected to a shaft, and a limiting frame is fixedly connected to one side of the shaft. The limiting frame is movably connected to one side of the hook.

[0010] As a preferred technical solution, the positioning component includes a positioning hole, which is opened inside the connecting block. A positioning rod is inserted into the positioning hole, and a slider is fixedly connected to one side of the positioning rod. The slider is slidably connected inside the fixed seat, and a screw is rotatably connected inside the fixed seat. A handwheel is fixedly connected to the end of the screw, and one side of the slider is threadedly connected to the screw. Guide grooves are opened on both sides of the interior of the fixed seat, and one side of the slider is slidably connected to the guide groove.

[0011] As the preferred technical solution,

[0012] As a preferred technical solution, the locking assembly includes a locking hole, which is opened on one side of the fixed base. An assembly block is fixedly connected to one side of the handwheel. A locking rod is slidably connected inside the assembly block. One side of the locking rod slides through the assembly block and is movably connected to the locking hole. A spring is fixedly connected inside the fixed base. One side of the spring is fixedly connected to one side of the locking rod. A pull rod is fixedly connected to the locking rod on the side of the spring.

[0013] In summary, the present invention has the following main advantages:

[0014] First, this utility model releases the handwheel restriction by locking the component, and uses the handwheel to drive the bidirectional screw to rotate, causing the slider on the screw surface to move. The slider drives the positioning rod to move, causing the positioning rod to leave the positioning hole of the connecting block. At this time, the connecting block is no longer fixed to the connecting groove, so the mounting base can be separated from the fixed base. Since the hook is fixed on the fixed base, the hook can be replaced quickly, avoiding the replacement of the whole piece, reducing material waste and lowering the cost of use.

[0015] Secondly, this utility model, by installing a force sensor on the fixed base, converts load information into an electrical signal when an item is hooked onto the hook. At this time, a micro motor can be used to drive the shaft to rotate, and the shaft drives the limit frame to rotate, moving the limit frame to the opening of the hook, thereby enhancing the anti-derailment performance and effectively reducing the risk of the lifting rope slipping due to vibration, shaking or impact during the lifting process, significantly improving the safety of cargo lifting. At the same time, before the hook is used, the limit frame is not located at the opening of the hook. This design not only avoids interfering with the normal hooking of items, but also greatly facilitates the use and operation of the hook. Attached Figure Description

[0022] Example

[0023] refer to Figures 1 to 5The fixed structure for lifting slings described in this embodiment includes a chain 1. A force sensor 3 is provided on one side of the chain 1. When an item is hung on the hook 6, the force sensor 3 works to convert the load information into an electrical signal, which facilitates the subsequent control of the limiting component 7. A fixed base 4 is fixedly connected to the bottom end of the force sensor 3. Connecting grooves 8 are provided on both sides of the bottom end of the fixed base 4. Connecting blocks 9 are inserted into the connecting grooves 8. A mounting base 5 is fixedly connected to the bottom end of the connecting block 9. A hook 6 is fixedly connected to the bottom end of the mounting base 5. A limiting component 7 is provided on one side of the fixed base 4. A positioning component 10 is provided on one side of the fixed base 4. A locking component 11 is provided on one side of the positioning component 10.

[0024] refer to Figure 2 The top of the force sensor 3 is fixedly connected to a locking ring 2, which is connected to the lower side of the chain 1; by setting the locking ring 2, the force sensor 3 is connected to the lower side of the chain 1.

[0025] refer to Figure 1-2 The limiting component 7 includes a micro motor 71, which is fixedly connected to one side of the fixed base 4. The output end of the micro motor 71 is fixedly connected to a shaft 72, and a limiting frame 73 is fixedly connected to one side of the shaft 72. The limiting frame 73 is movably connected to one side of the hook 6. By setting the limiting component 7, the micro motor 71 drives the shaft 72 to rotate, which in turn drives the limiting frame 73 to rotate on the fixed base 4. By moving the limiting frame 73 to the hook 6, the lifting rope of the goods can be prevented from slipping from the hook 6.

[0026] refer to Figure 5 The positioning component 10 includes a positioning hole 101, which is located inside the connecting block 9. A positioning rod 102 is inserted into the positioning hole 101. A slider 103 is fixedly connected to one side of the positioning rod 102. The slider 103 is slidably connected inside the fixed base 4. A screw 104 is rotatably connected inside the fixed base 4. A handwheel 105 is fixedly connected to the end of the screw 104. One side of the slider 103 is threadedly connected to the screw 104. Guide grooves 106 are provided on both sides of the interior of the fixed base 4. One side of the slider 103 is slidably connected to the guide groove 106; by setting the positioning component 10, rotating the handwheel 105 drives the screw 104 to rotate, causing the two sliders 103 on the surface of the screw 104 to move. The slider 103 drives the positioning rod 102 to move. After the positioning rod 102 leaves the positioning hole 101, the connecting block 9 separates from the connecting groove 8, and the hook 6 can be removed and replaced. After the hook 6 is replaced, the connecting block 9 is reinserted into the connecting groove 8, and the handwheel 105 is rotated again to fix the positioning rod 102 to the positioning hole 101. At this time, the connecting block 9 is fixed to the connecting groove 8.

[0027] refer to Figure 4 The locking assembly 11 includes a locking hole 111, which is located on one side of the fixed base 4. An assembly block 113 is fixedly connected to one side of the handwheel 105. A locking rod 112 is slidably connected inside the assembly block 113. One side of the locking rod 112 slides through the assembly block 113 and is movably connected to the locking hole 111. A spring 114 is fixedly connected inside the fixed base 4. One side of the spring 114 is fixedly connected to one side of the locking rod 112. The locking rod 112 is located within the spring 115. A pull rod 115 is fixedly connected to one side of the hook 6. By setting a locking component 11, when the connecting block 9 is connected to the connecting groove 8, the pull rod 115 is pulled, the pull rod 115 causes the spring 114 to deform, and at the same time causes the locking rod 112 to move. The locking rod 112 leaves the locking hole 111, and the handwheel 105 can be rotated. When the positioning rod 102 is connected and fixed to the positioning hole 101, the pull rod 115 is released. At this time, the spring 114 returns to its deformation, and the locking rod 112 is inserted into the locking hole 111 to prevent the handwheel 105 from rotating and stabilize the installation of the hook 6.

[0028] Operating principle and advantages: Pulling the lever 115 causes the spring 114 to deform, simultaneously moving the locking lever 112. The locking lever 112 disengages from the locking hole 111, allowing the handwheel 105 to rotate. Once the positioning lever 102 is connected and fixed to the positioning hole 101, releasing the lever 115 causes the spring 114 to return to its original shape, and the locking lever 112 inserts into the locking hole 111, preventing the handwheel 105 from rotating and stabilizing the hook 6 installation. The mounting base 5 is then inserted into the connecting grooves 8 on both sides of the bottom of the fixing base 4 via the connecting block 9 at its bottom. At this point, the connecting block 9 and the connecting groove 8 are initially connected. Then, turn the handwheel 105, which drives the screw 104 to rotate. Since the slider 103 is threadedly connected to the screw 104, and one side of the slider 103 is slidably connected to the guide groove 106 inside the fixed seat 4, the rotation of the screw 104 causes the slider 103 to move along the screw 104 under the guidance of the guide groove 106. The slider 103 drives the positioning rod 102 to move, so that the positioning rod 102 is inserted into the positioning hole 101 inside the connecting block 9, thereby fixing the connecting block 9 to the connecting groove 8, and thus completing the fixed connection between the mounting base 5 and the fixed seat 4. When an item is hung on the hook 6, Force sensor 3 starts working, converting the sensed load information into an electrical signal. The electrical signal triggers micro motor 71 to work, driving shaft 72 to rotate. Shaft 72 drives limit bracket 73 to rotate on fixed seat 4. Limit bracket 73 moves to the opening of hook 6, limiting the lifting rope and enhancing anti-slip performance. This effectively reduces the risk of lifting rope slippage due to vibration, shaking, or impact during lifting. When hook 6 needs to be replaced, pull rod 115 in locking assembly 11 is pulled. Pull rod 115 causes spring 114 to deform, simultaneously moving locking rod 112 to lock the hook. When the fixed rod 112 leaves the locking hole 111, the rotation restriction of the handwheel 105 is released. When the handwheel 105 is rotated, the handwheel 105 drives the screw 104 to rotate. Under the rotation of the screw 104, the slider 103 moves along the guide groove 106. The slider 103 drives the positioning rod 102 to move, so that the positioning rod 102 leaves the positioning hole 101 inside the connecting block 9. At this time, the connecting block 9 and the connecting groove 8 are no longer fixed. The mounting base 5 is removed from the fixed base 4. Since the hook 6 is fixed at the bottom of the mounting base 5, the hook 6 is quickly separated from the fixed base 4, and the hook 6 can be replaced.
