Description

Technical Field

[0001] This utility model relates to the field of crane hook technology, and in particular to a crane hook assembly with an anti-sway control mechanism. Background Technology

[0002] Cranes are important lifting equipment widely used in construction sites, logistics warehouses, dock loading and unloading and other places. The hook assembly is the key execution structure connecting the lifting mechanism and the lifted object. It is directly related to the safety and stability of lifting operations. When the crane is lifting and lowering, especially outdoors under the influence of wind, the hook and the heavy object being lifted will often swing. Therefore, anti-sway mechanism is required.

[0003] A Chinese patent has been published: a hook mechanism for a crane, patent announcement number: CN215592355U. The patent states that "a lifting wheel is provided between two side plates, a connecting shaft is provided between the two side plates and at the lower end, two connecting screws are also provided between the two side plates, a sleeve is sleeved on the outside of the connecting screws, and an arc-shaped plate is provided between the two sleeves."

[0004] Although the hook is slidably connected to the upper surface of the curved plate via bolts and nuts, with the bolts sliding within the grooves of the curved plate to improve the hook's load-bearing capacity, the crane hook mechanism lacks a dedicated anti-sway control structure. This makes it impossible to effectively suppress the swaying or swinging of the hook and the load during operation. Consequently, in actual use, especially outdoors under wind conditions or during crane start-up and braking, the hook and its load are prone to continuous swaying and swinging. Due to the lack of effective sway suppression measures, the swaying of the hook not only reduces the positioning accuracy of the lifting operation and affects work efficiency, but also easily causes the load to collide with surrounding obstacles or building structures, posing significant safety hazards. This increases the difficulty of control for operators and can easily lead to equipment damage or personal injury accidents, severely restricting the reliability and safety of crane equipment in complex environments. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a crane hook assembly with an anti-sway control mechanism to solve the problem that the crane hook mechanism lacks a dedicated anti-sway control structure. During the swaying process, the positioning accuracy of the lifting operation not only decreases and the operation efficiency is affected, but also the lifted object is prone to collide with surrounding obstacles or building structures, which poses a great safety hazard.

[0006] To achieve the above objectives, this utility model provides a crane hook assembly with an anti-sway control mechanism, comprising a hook housing, wherein there are two hook housings, which are fixed together by bolts. A rotating wheel is rotatably connected between the opposing surfaces of the two hook housings, and a rotating block is rotatably connected between the opposing surfaces of the two hook housings. A hook for lifting objects is fixedly connected to the bottom of the rotating block. A first mounting plate is fixedly connected to both sides of the rotating block. A second mounting plate is fixedly connected between the opposing surfaces of the two hook housings. Two damping rods are rotatably connected between the bottom ends of the two second mounting plates and the top ends of the two first mounting plates. A first spring is fixedly connected to both ends of the outer wall of each of the two damping rods. An anti-sway mechanism for the hook to swing during placement is provided on the outer wall of each of the two hook housings.

[0007] Preferably, the anti-sway mechanism includes a support rod rotatably connected between two hook housings. Two support rods are provided and arranged opposite each other. Each support rod has a sliding groove on its side wall. Each hook housing has a slide rail fixedly connected to its side wall. A slider is slidably connected to the outer wall of each slide rail. A set of adjusting rods is fixedly connected to each side of the two sliders. A sliding rod is fixedly connected between the opposite ends of the two sets of adjusting rods, and the sliding rod is located inside the sliding groove. A lifting ring is fixedly connected to the bottom end of each support rod.

[0008] Preferably, a handle is fixedly connected to the side wall of the slider, and an adjusting plate is rotatably connected to the top of the handle. The adjusting plate is V-shaped, and a second spring is fixedly connected between the bottom of the adjusting plate and the top of the handle. A pull block is fixedly connected to one end of the adjusting plate. A limiting post slides through the top of the slider. Multiple equally spaced and evenly distributed limiting grooves are provided on the side wall of the slide rail. One end of the limiting post extends into the interior of the limiting groove and is mutually adapted. A fixing block is fixedly connected to the end of the limiting post near the handle. A pull ring is fixedly connected to the side wall of the fixing block, and the pull block is located inside the pull ring.

[0009] Preferably, the two damping rods located between the first mounting plate and the second mounting plate are inclined.

[0010] Preferably, the outer wall of the adjustment plate is arc-shaped, and both the handle and the outer wall of the adjustment plate are provided with anti-slip grooves.

[0011] Preferably, the inner diameter of the pull ring is larger than the outer diameter of the pull block.

[0012] The beneficial effects of this utility model are:

[0013] 1. This crane hook assembly with anti-sway control mechanism addresses the problems of easy swaying and control difficulties caused by the lack of effective anti-sway structures in existing technologies. When the hook swings, it drives the connected first mounting plate to rotate, thereby compressing the damping rod and the first spring on one side. The damping rod provides damping force, and the first spring stores elastic energy when compressed and releases it slowly during the swing back by cooperating with the damping rod, thus forming a counterforce. This effectively reduces the swing speed and amplitude of the hook, improving the stability and safety of the operation. Furthermore, the two support rods cooperate with the lifting ring to construct an approximately triangular stable support structure. This structure can effectively distribute the center of gravity of the load during lifting, enhance the suspension stability of the lifted goods, and significantly reduce the linkage swing amplitude of the overall structure when the goods sway, further improving the safety and anti-sway effect of the lifting operation.

[0014] 2. The crane hook assembly with anti-sway control mechanism, through adjustable handles, adjusting plates, second springs, pull blocks, limit posts, sliders, slide rails, adjusting rods and slide bars, can quickly adjust the unfolding angle of the support rod when it is necessary to adapt to goods of different sizes, significantly improving the versatility and ease of use of the equipment.

[0024] like Figures 1 to 4 As shown, a crane hook assembly with an anti-sway control mechanism includes a hook housing 1. Two hook housings 1 are provided, fixed together by bolts. A rotating wheel 2 is rotatably connected between the opposing faces of the two hook housings 1. A rotating block 3 is rotatably connected between the opposing faces of the two hook housings 1. A hook 4 for lifting objects is fixedly connected to the bottom of the rotating block 3. First mounting plates 5 are fixedly connected to both sides of the rotating block 3. A second mounting plate 6 is fixedly connected between the opposing faces of the two hook housings 1. Two damping rods 7 are rotatably connected between the bottom ends of the two second mounting plates 6 and the top ends of the two first mounting plates 5. The two damping rods 7 located between the first mounting plates 5 and the second mounting plates 6 are inclined. A first spring 8 is fixedly connected to both ends of the outer wall of each damping rod 7. An anti-sway mechanism for preventing the hook 4 from swinging is provided on the outer wall of each of the two hook housings 1.

[0025] Further, see attached document. Figures 1 to 4As shown, the anti-sway mechanism includes two support rods 9 rotatably connected between two hook housings 1. The support rods 9 are arranged opposite each other. Each support rod 9 has a groove 10 on its side wall. Each hook housing 1 has a slide rail 11 fixedly connected to its side wall. Each slide rail 11 has a slider 12 slidably connected to its outer wall. Each slider 12 has a set of adjusting rods 13 fixedly connected to its two sides. A sliding rod 14 is fixedly connected between the opposite ends of the two sets of adjusting rods 13, and the sliding rod 14 is located inside the groove 10. Each support rod 9 has a hanging ring 15 fixedly connected to its bottom end. A handle 16 is fixedly connected to the side wall of the slider 12. The top of the handle 16 rotates... An adjustment plate 17 is connected, and the adjustment plate 17 is V-shaped. A second spring 18 is fixedly connected between the bottom of the adjustment plate 17 and the top of the handle 16. A pull block 19 is fixedly connected to one end of the adjustment plate 17. A limit post 20 slides through the top of the slider 12. Multiple equally spaced and evenly distributed limit grooves 21 are opened on the side wall of the slide rail 11. One end of the limit post 20 extends into the interior of the limit groove 21 and is adapted to each other. A fixing block 22 is fixedly connected to the end of the limit post 20 near the handle 16. A pull ring 23 is fixedly connected to the side wall of the fixing block 22. The pull block 19 is inside the pull ring 23. The inner diameter of the pull ring 23 is larger than the outer diameter of the pull block 19.

[0026] When in use, the anti-sway control mechanism is first connected to two lifting rings 15 and hook 4 via an external chain to form a lifting structure. During operation, the crane is connected to the rotating wheel 2 via an external lifting mechanism. The rotating wheel 2 drives the hook 4 and the connected lifting rings 15 to lift the object together. When the hook shell 1 shakes due to environmental wind interference or external forces such as crane rotation, the shaking force is first transmitted to the hook 4, causing the hook 4 to shake. During the swing of the hook 4, it will drive the first mounting plate 5 connected to it to rotate, thereby squeezing... The damping rod 7 and the first spring 8 set on one side form a damping buffer force to slow down the swing process. The damping rod 7 provides a certain damping force during the movement, and is then compressed by the first spring 8. The first spring 8 stores some energy through elastic deformation, and slowly releases this energy in conjunction with the damping rod 7 when the hook 4 swings back or decelerates, forming a reverse force. This reverses the swing trend of the hook 4, effectively delaying the swing period of the hook 4 and reducing the swing amplitude, thus achieving a good anti-swing effect and improving the stability and safety during the hoisting process.

[0027] The object is lifted by two support rods 9 together with the lifting ring 15 and the hook 4. The three form a stable support structure with an approximately triangular distribution. This structure can effectively distribute the load and enhance the stability of the goods. In this way, when the goods sway, the linkage swing phenomenon of the hook shell 1 and the hook 4 as a whole is reduced, and the anti-sway effect is further improved.

[0028] When the angle of the support rod 9 needs to be adjusted to accommodate goods of different diameters, the operator can hold the handle 16 and apply pressure to the adjusting plate 17. When the adjusting plate 17 is pressed, it will rotate around its axis and compress the second spring 18, causing the other end of the adjusting plate 17 to lift and drive the pull block 19 to rotate synchronously. During the rotation of the pull block 19, it will pull the fixed block 22 connected to it. The fixed block 22 will then pull the limiting post 20 set in the limiting groove 21, thereby releasing the limiting state of the slider 12. At this time, the operator can continue to apply an upward operating force to the handle 16, causing the slider 12 to slide on the outer wall of the slide rail 11, driving the adjusting rod 13 to move upward synchronously, and causing the slide rod 14 to slide in the slide groove 10, thereby driving the support rod 9 to rotate. When the two support rods 9 are opened to both sides, the supporting diameter formed by them is significantly increased, which can better cooperate with the lifting ring 15 and the hook 4 to stably lift goods of different sizes, improving the adaptability and practicality of the entire hook assembly.

[0029] The anti-sway mechanism addresses the problems of easy swaying and difficulty in control of the hook 4 and its load during operation caused by the lack of an effective anti-sway structure in existing technologies. When the hook 4 swings, it drives the connected first mounting plate 5 to rotate, thereby compressing the damping rod 7 and the first spring 8 set on one side. The damping rod 7 provides damping force, and the first spring 8 stores elastic energy when compressed and releases it slowly in cooperation with the damping rod 7 during the swing back, thus forming a counterforce. This effectively reduces the swing speed and amplitude of the hook 4, improving the stability and safety of the operation. Furthermore, the two support rods 9 cooperate with the lifting ring 15 to construct an approximately triangular stable support structure. This structure can effectively distribute the center of gravity of the load during lifting, enhance the suspension stability of the lifted goods, and significantly reduce the linkage swing amplitude of the overall structure when the goods sway, further improving the safety and anti-sway effect of the lifting operation.

[0030] Further, see attached document. Figure 4 As shown, the outer wall of the adjustment plate 17 is arc-shaped, and anti-slip grooves are provided on the outer walls of both the handle 16 and the adjustment plate 17. The anti-slip grooves increase the friction between the user's hand and the handle 16 and the adjustment plate 17.
