Description

Technical Field

[0001] This utility model belongs to the field of lifting machinery, and in particular relates to an anti-disengagement lifting device. Background Technology

[0002] With continuous technological advancements and increasingly stringent safety requirements, people are placing higher demands on the safety and reliability of lifting equipment. Traditional lifting equipment may be prone to cargo detachment during lifting due to design flaws, poor manufacturing quality, or improper use. For example, some lifting equipment has inadequate anti-detachment devices, or is prone to wear and failure after prolonged use; some lifting equipment also struggles to ensure a secure connection when lifting irregularly shaped goods, increasing the likelihood of detachment.

[0003] Existing equipment often has hook lengths that cannot be adjusted according to actual needs, leading to frequent hook replacements during operations, reducing work efficiency. Furthermore, the force on the slings is often not properly balanced, and unsuitable lengths can cause swaying. Dynamic forces during lifting can also cause loosening, resulting in hook instability and reduced safety. Therefore, we propose an anti-disengagement lifting device. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-disengagement lifting device. By using a threaded rod and a reinforcing plate, it solves the problem that the length of the hook cannot be adjusted according to actual needs during use. This leads to frequent hook replacements during operation, reducing work efficiency. At the same time, it makes it difficult to achieve a more reasonable stress on the slings, and the unsuitable length can cause swaying. During lifting, dynamic forces can also cause loosening, resulting in unstable hook position and reduced safety.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an anti-disengagement lifting device, comprising a connecting rod, a threaded rod threaded to the inner wall of the connecting rod, a plurality of hanging rods fixedly connected to the outer wall of the threaded rod, bolts slidably connected to the inner wall of the hanging rods, and an adjustment and reinforcement mechanism provided on the outer wall of the threaded rod. The adjustment and reinforcement mechanism includes a plurality of fixing plates, the fixing plates being rotatably connected to the threaded rods, and limit blocks being fixedly connected to the outer wall of the plurality of threaded rods near the fixing plates, the limit blocks being slidably connected to the connecting rod.

[0007] The above technical solution allows the length of the equipment to be freely adjusted by using a threaded rod, which makes the stress on the slings more reasonable.

[0008] Furthermore, a nut is threaded onto the outer wall of the bolt, and a retaining ring is fixedly connected to the outer wall of the threaded rod on the side away from the fixing plate.

[0009] The above technical solution allows the rotating rod to rotate inside the fixed ring, preventing the threaded rod from rotating due to the rotation of the hook.

[0010] Furthermore, a rotating rod is rotatably connected to the inner wall of the fixing ring, and a hook is fixedly connected to the outer wall of the rotating rod on the side away from the fixing plate.

[0011] The above technical solution allows items to be hung up with hooks, making transportation more convenient and faster, and improving work efficiency.

[0012] Furthermore, screws are rotatably connected to the inner walls of several of the fixing plates, and a turntable is fixedly connected to the outer wall of the side of the screws away from the fixing plates.

[0013] The above technical solution uses the rotation of screws to move the reinforcing plate, allowing the reinforcing plate to fit against the connecting rod.

[0014] Furthermore, the outer walls of several screws are threaded with reinforcing plates, and the outer walls of the reinforcing plates near the fixing plate are fixedly connected with several limiting plates.

[0015] The above technical solution achieves a tight fit between the reinforcing plate and the connecting rod, thereby fixing the threaded rod.

[0016] Furthermore, the limiting plate is slidably connected to the connecting rod, and a rolling rod is fixedly connected to the inner wall of the hook.

[0017] The above technical solution uses a rolling rod to limit the locking block, preventing it from moving during rotation.

[0018] Furthermore, a locking block is rotatably connected to the outer wall of the rolling rod, and several support plates are fixedly connected to the outer wall of the hook.

[0019] The above technical solution protects items by having the locking block and hook fit together, preventing items from falling off the hook.

[0020] Furthermore, a damping rod is fixedly connected to the inner wall of the support plate, and a spring is fixedly connected to the outer wall of the damping rod.

[0021] The above technical solution automatically engages the locking block with the hook through spring compression, maintaining the engagement between the locking block and the hook during equipment use.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model incorporates a threaded rod. After the hook is installed, the fixing ring can be rotated, causing the threaded rod to rotate as well. The threaded rod then rotates within the connecting rod, moving as it rotates. This movement of the threaded rod, in turn, moves the limiting block and the fixing plate. The limiting block then slides against the connecting rod. The movement of the fixing plate moves the screw, which in turn moves the reinforcing plate and the limiting plate. This increases the overall length of the equipment, improving operational flexibility. The length can be adjusted according to actual needs, eliminating the need for frequent hook replacements and improving work efficiency. Adjusting the hook length allows for more reasonable stress distribution on the slings, reducing swaying caused by unsuitable length.

[0024] 2. This utility model incorporates a reinforcing plate. When the screw rotates, the reinforcing plate moves, eventually adhering tightly to the surface of the connecting rod. This friction secures the threaded rod. After securing, the item is hung on the hook. Placing the item presses down on the locking block, and the movement of the locking block compresses the spring. Once the item is placed, the locking block is no longer under pressure, and the spring rebounds, compressing the locking block and resetting it. This reset blocks the notch on the hook, enhancing safety and preventing loosening due to dynamic forces during lifting. The fixed design ensures the threaded rod remains stable during lifting, preventing accidents caused by loosening and improving safety. It also enhances the anti-falling effect of the item.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-5 As shown, this utility model is an anti-disengagement lifting device, including a connecting rod 1. The inner wall of the connecting rod 1 is threaded with a threaded rod 101. The outer wall of the threaded rod 101 is fixedly connected with several hanging rods 102. The inner wall of the hanging rods 102 is slidably connected with bolts 103. The outer wall of the threaded rod 101 is provided with an adjustment and reinforcement mechanism 2. The adjustment and reinforcement mechanism 2 includes several fixing plates 201. The fixing plates 201 are rotatably connected to the threaded rod 101. The outer wall of the several threaded rods 101 near the fixing plates 201 is fixedly connected with a limit block 202. The limit block 202 is slidably connected to the connecting rod 1.

[0036] The outer wall of bolt 103 is threaded with a nut 104, and the outer wall of threaded rod 101 away from the fixing plate 201 is fixedly connected with a fixing ring 105.

[0037] A rotating rod 106 is rotatably connected to the inner wall of the fixed ring 105, and a hook 107 is fixedly connected to the outer wall of the rotating rod 106 on the side away from the fixed plate 201.

[0038] Screws 203 are rotatably connected to the inner walls of several fixed plates 201, and a turntable 204 is fixedly connected to the outer wall of the side of the screws 203 away from the fixed plates 201.

[0039] A number of screws 203 are threadedly connected to a reinforcing plate 205 on their outer walls, and a number of limiting plates 206 are fixedly connected to the outer wall of one end of the reinforcing plate 205 near the fixing plate 201.

[0040] The limiting plate 206 is slidably connected to the connecting rod 1, and the inner wall of the hook 107 is fixedly connected to the rolling rod 207.

[0041] The outer wall of the rolling rod 207 is rotatably connected to a locking block 208, and the outer wall of the hook 107 is fixedly connected to several support plates 209.

[0042] A damping rod 211 is fixedly connected to the inner wall of the support plate 209, and a spring 210 is fixedly connected to the outer wall of the damping rod 211.

[0043] One specific application of this embodiment is:

[0044] When the operator needs to use the equipment, first unscrew the nut 104 from the bolt 103, then remove the bolt 103. After removing the bolt 103, hang the hanging rod 102 on the lifting device, then reinstall the bolt 103 and tighten the nut 104 to secure it and prevent it from falling off during use. After the hook is installed, the fixing ring 105 can be rotated. When the fixing ring 105 rotates, it drives the threaded rod 101 to rotate. Then the threaded rod 101 will rotate in the connecting rod 1. When the threaded rod 101 rotates, it will move. When the threaded rod 101 moves, it will drive the limit block 202 and the fixing plate 201 to move. Then the limit block 202 will slide against the connecting rod 1. When the fixing plate 201 moves, it will drive the screw 203 to move. When the screw 203 moves, it will drive the reinforcing plate 205 and the limit plate 206 to move, making the overall length of the equipment longer. After adjusting to a suitable position... After the length is measured, the turntable 204 can be rotated. When the turntable 204 rotates, it will drive the screw 203 to rotate. Then the screw 203 will rotate within the fixing plate 201. When the screw 203 rotates, it will drive the reinforcing plate 205 to move. Then the reinforcing plate 205 will be moved until it is tightly attached to the surface of the connecting rod 1. When the reinforcing plate 205 is tightly attached to the surface of the connecting rod 1, the threaded rod 101 will be fixed due to friction. After the fixing is completed, the item is hung on the hook 107. When the item is placed, the locking block 208 will be pressed down. When the locking block 208 moves, it will squeeze the spring 210. After the item is placed, the locking block 208 will not be subjected to downward pressure. When the locking block 208 is not subjected to downward pressure, the spring 210 will rebound. When the spring 210 rebounds, it will squeeze the locking block 208, causing the locking block 208 to reset. After the locking block 208 resets, it will block the notch on the hook 107, preventing the item from falling off the notch.
