Description

Technical Field

[0001] This utility model relates to the technical field of lifting equipment, specifically to an insulated rotating hook assembly that can work with guide columns to prevent swaying. Background Technology

[0002] A swivel hook is a hook-type pulley block connected to a crane via a wire rope. It is a device used for lifting heavy objects, consisting of a wire rope passing around several pulleys at a time. It can be installed on cranes, hoists, lifting equipment, and other equipment. Swivel hooks are commonly used in lifting equipment, hoisting machinery, industrial production lines, and other occasions for lifting, handling, loading, and unloading heavy objects.

[0003] Existing lifting devices require personnel to attach slings to the hook during operation and to remove the slings to release the load after lifting. Therefore, in addition to the control personnel, one or more auxiliary personnel are needed, which increases the operating cost. Furthermore, during the lifting process, personnel are positioned below the hook, increasing the risk of injury. The operation is also cumbersome and inconvenient (Chinese Patent Application No. CN202322953035.4, Application Date: 2023-11-01) for an electric rotating hook assembly. The device includes a mounting base with a pair of side plates fixedly mounted on top. A protective box is fixedly mounted on top of the side plates, and multiple sets of lifting wheels are mounted on the protective box via a rotating shaft. A hook assembly is installed at the bottom of the mounting base. A strong magnet on the control block attracts the sling. Simultaneously, starting the second motor rotates the hook below the control block, allowing its end to pass through the sling and complete the loading operation. When releasing the sling, the second motor is again activated, rotating the hook to the side of the control block, at which point the sling automatically slides off the hook. The entire process requires no manual operation, making it highly convenient to use. Furthermore, this device eliminates any handling or movement, keeping personnel away from the hook and goods, thus minimizing potential hazards to personnel and further improving safety.

[0004] During hoisting, due to the crane's starting, stopping, acceleration, deceleration, vibration, and shaking during operation, or factors such as wind at the hoisting site, if the hook does not have a self-locking function, the heavy object can easily slip off the hook; this can cause the heavy object to fall, causing serious injury and damage to personnel, equipment, and facilities below, and triggering a major safety accident.

[0005] Therefore, we proposed an insulated rotating hook assembly that can work with the guide column to prevent swaying, which can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an insulated rotating hook assembly that can work with the guide column to prevent swaying, so as to solve the problem mentioned in the background art that the heavy objects cannot be locked, causing the heavy objects to fall off due to the swaying or displacement of the hook, which not only causes serious injury and damage to the personnel, equipment and facilities below, but also causes major safety accidents.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an insulated rotating hook assembly that can cooperate with guide columns to prevent swaying, comprising a frame, guide wheels fixedly connected to the outer side of the frame, the guide wheels being symmetrically distributed about the center of the frame, and a drive base bolted to the inner wall of the frame, while a bearing yoke plate fixedly connected to one end of the inner wall of the frame near the drive base; a hook beam rotatably connected inside the bearing yoke plate, and a hook head bolted to the lower end of the hook beam, and a fixing plate provided on the surface of the bearing yoke plate near the hook head through a buffer and shock absorption component, while a connecting plate fixedly connected to the upper outer side of the hook head; a limit groove is formed inside the hook head, and a sliding rod is slidably connected inside the hook head, and a limit block is provided on the inner wall of the hook head through a self-locking component, while the surface of the limit block is arc-shaped.

[0008] As a preferred technical solution of this application, a support plate is fixedly connected to the upper end of the sliding rod, and the support plate is slidably disposed inside the hook head.

[0009] As a preferred technical solution of this application, one end of the support spring is fixedly connected to the lower surface of the support plate, and the other end of the support spring is fixedly connected to the hook.

[0010] As a preferred technical solution of this application, the hook head is slidably connected to a locking rod, the surface of the locking rod is arc-shaped, and the outer side of the locking rod protrudes and fits against the surface of the limiting groove.

[0011] As a preferred technical solution of this application, the self-locking assembly includes a sliding frame rotatably disposed on the surface of the sliding rod, and the other end of the sliding frame is fixedly connected to the locking rod.

[0012] As a preferred technical solution of this application, the buffer and shock absorption assembly includes a buffer spring fixedly connected to the surface of the fixed plate, and the other end of the buffer spring is fixedly connected to the connecting plate.

[0013] As a preferred technical solution of this application, one end of the damper is fixedly connected to the upper end of the connecting plate, and the other end of the damper is fixedly connected to the fixing plate, and the dampers are symmetrically distributed about the center of the connecting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The three-in-one drive device allows the hook to rotate to a certain angle, ensuring the suspended item is better aligned with the workshop layout for easier transport. Simultaneously, with the pulleys extended, the rotary drive section is positioned in the middle. When the load rotates, the extended pulleys overcome the load's rotational inertia, while the pulleys remain unaffected. The structure is reasonable. When the trolley starts at high speed, the hook assembly follows the guide pulleys into the guide frame, preventing the load from swinging and improving safety and efficiency. Specific details are as follows: 1. The self-locking mechanism of the hook not only maintains effective locking of the load, providing double protection for the lifting process and preventing personal injury and property damage caused by the load falling, but also greatly reduces the risk of the load accidentally falling off during lifting. Furthermore, it offers higher safety and reliability when dealing with external interference, ensuring that lifting tasks can be completed safely under various adverse conditions.

[0015] 2. The buffer spring can effectively absorb the impact force from the outside through its own elastic deformation, avoiding the impact force from acting directly on the hook and related components. At the same time, the damper can suppress the vibration of the hook caused by external interference. Through the viscous resistance of the internal medium, the vibration energy is converted into heat energy and dissipated, so that the hook can return to stability as soon as possible. This effectively reduces the swing amplitude and duration of the hook, ensuring the stability of the lifting process. It not only improves the accuracy of lifting positioning, but also reduces the damage to components, reduces the frequency of component replacement, and reduces maintenance costs.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7 The present invention provides the following technical solution: an insulated rotating hook assembly that can be used in conjunction with a guide post to prevent swaying.

[0026] Example 1: The hook beam 4, load-bearing yoke 3, and drive base 2 allow the hook assembly to enter the guide frame via guide pulleys, preventing the load from swinging and improving the device's working efficiency. Figures 1-2 As shown: It includes a frame 1, with guide wheels 17 fixedly connected to the outer side of the frame 1, and the guide wheels 17 are symmetrically distributed about the center of the frame 1. The inner wall of the frame 1 is bolted to a drive base 2. At the same time, a load-bearing yoke plate 3 is fixedly connected to the inner wall of the frame 1 near the drive base 2. A hook beam 4 is rotatably connected inside the load-bearing yoke plate 3, and a hook head 5 is bolted to the lower end of the hook beam 4. A fixed plate 13 is set on the surface of the load-bearing yoke plate 3 near the hook head 5 through a buffer and shock-absorbing component. At the same time, a connecting plate 16 is fixedly connected to the upper outer side of the hook head 5. A limit groove 6 is opened inside the hook head 5, and a sliding rod 8 is slidably connected inside the hook head 5. A limit block 7 is set on the inner wall of the hook head 5 through a self-locking component, and the surface of the limit block 7 is arc-shaped.

[0027] Workers activate the device to bring hook 5 into contact with the load. The self-locking mechanism inside hook 5 causes the locking rod 12 to extend from inside hook 5 and engage with the outer side of hook 5, thus locking the load onto the surface of hook 5. This significantly reduces the risk of the load accidentally falling off during hoisting (e.g., ...). Figure 1 As shown), after the pulleys inside the device are opened, the rotary drive part is arranged in the middle. When the load rotates, the opened pulleys can overcome the rotational inertia of the load, while the pulleys remain unaffected. The structure is reasonable. When the trolley starts at high speed, the hook assembly enters the guide frame according to the guide pulley, and the load will not swing, improving the working efficiency of the device (e.g., Figure 2As shown in the figure, the damper 15 and buffer spring 14 inside the device can reduce damage to components, reduce maintenance costs, and improve the accuracy of hoisting and positioning.

[0028] In Example 2, unlike Example 1, the supporting spring 10, limiting groove 6, and sliding frame 11 effectively lock the heavy object, providing double protection during the hoisting process and preventing personal injury and property damage caused by the falling object. Figures 3-5 As shown: A support plate 9 is fixedly connected to the upper end of the sliding rod 8, and the support plate 9 is slidably disposed inside the hook head 5. One end of the support spring 10 is fixedly connected to the lower surface of the support plate 9, and the other end of the support spring 10 is fixedly connected to the hook head 5. A locking rod 12 is slidably connected inside the hook head 5, and the surface of the locking rod 12 is arc-shaped. The outer side of the locking rod 12 protrudes and fits against the surface of the limiting groove 6. The self-locking assembly includes a sliding frame 11 rotatably disposed on the surface of the sliding rod 8, and the other end of the sliding frame 11 is fixedly connected to the locking rod 12.

[0029] As the device lifts the object, when the load to be transported comes into contact with the hook head 5, the load presses against the upper support plate 9 of the sliding rod 8, causing the sliding rod 8 to slide inside the hook head 5 and pushing the support spring 10 on the surface of the support plate 9 to contract towards the inner wall of the hook head 5 (e.g., Figure 3 and Figure 4 As shown, as the sliding rod 8 slides inside the hook head 5, it drives the sliding frame 11 on the surface to slide towards the inner wall of the hook head 5. When the sliding frame 11 contacts the limiting block 7 on the inner wall of the hook head 5, because the surface of the limiting block 7 is arc-shaped, the limiting block 7 pushes the sliding frame 11 to rotate outside the sliding rod 8, and pushes the locking rod 12 at the other end to slide inside the hook head 5 under the constraint of the limiting groove 6. At the same time, the locking rod 12 extends out from inside the hook head 5 and fits against the outer side of the hook head 5 (as shown). Figure 5 As shown in the figure, this completes the locking of the weight on the surface of the hook head 5, greatly reducing the risk of the weight accidentally falling off during the hoisting process.

[0030] In embodiment three, unlike embodiment two, the fixed plate 13, damper 15, and connecting plate 16 effectively absorb external impact forces, preventing the impact forces from directly acting on the hook and related components. Figures 6-7 As shown: The buffer and shock absorption assembly includes a buffer spring 14 fixedly connected to the surface of the fixed plate 13, and the other end of the buffer spring 14 is fixedly connected to a connecting plate 16. One end of the damper 15 is fixedly connected to the upper end of the connecting plate 16, and the other end of the damper 15 is fixedly connected to the fixed plate 13. The dampers 15 are symmetrically distributed about the center of the connecting plate 16.

[0031] As the device starts, the crane begins to operate, and the hook 5 comes into contact with the load, generating a significant impact force. Upon receiving this impact force, the buffer spring 14 fixed to the surface of the fixed plate 13 immediately compresses and deforms due to its elastic properties. A portion of the impact force is converted into its own elastic potential energy and stored, making the transmission of the impact force smoother. Simultaneously, when the damper 15 connected to the upper end of the connecting plate 16 is displaced due to the compression of the buffer spring 14, a damping force is generated inside the damper 15, dissipating the impact energy into heat energy and other forms of energy (e.g., Figure 6 and Figure 7 (As shown) This ensures that the entire system can quickly stabilize after the hook 5 comes into contact with the load, ensuring that the impact on the hook and related structures is within a safe range, and guaranteeing the stable operation of the crane in subsequent lifting operations.
