Description

Technical Field

[0001] This utility model relates to the field of suspension components technology, and in particular to a suspension assembly for an electric hook. Background Technology

[0002] Electric lifting hooks are devices specifically designed for lifting and moving heavy objects, especially suitable for applications requiring precise control and automated operation. Compared to traditional manual or mechanical hooks, electric lifting hooks offer greater efficiency, safety, and flexibility.

[0003] The existing announcement number is CN203638964U, entitled "A Suspension Device for a Crane," which includes a hook part, a support column, and a hanger part cast as one piece. The hook part is located near the lower end of the support column, and the hanger part is located near the upper end of the support column, with the hanger part positioned above the hook part. The beneficial effect of this utility model is that by adding a hanger above the hook, the hook and hanger can simultaneously perform a suspension function, effectively reducing the swaying amplitude of the goods and ensuring the safe operation of on-site personnel.

[0004] However, during the suspension process of the aforementioned hook, the lack of an inertial buffer component causes the hoisted goods to sway as the hook moves. If the lifting or moving speed is too fast, the swaying of the goods will increase, thus posing a safety hazard of the goods falling. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a suspension component for electric hooks.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a suspension assembly for an electric hook, including a hook body, a suspension component, and an installation component. The hook body includes a hook plate frame, with a lower hook rotatably connected to the bottom end of the hook plate frame, and a hanging column horizontally inserted through and limited in the middle of the top surface of the hook plate frame. The suspension component includes a rotating plate, which is horizontally arranged above the hook plate frame, and a hanging plate is vertically fixed on the bottom surface of the rotating plate. The hanging plate and the hanging column are inserted through and inserted. An installation component is vertically connected and assembled above the rotating plate. Perforated plates are fixed to the top of the vertical end faces on both sides of the hook plate frame, and two first damping rods are vertically and symmetrically arranged above the perforated plates. The upper and lower ends of the two first damping rods are horizontally fixed with rotating columns, and the rotating columns at both ends of the two first damping rods are rotatably connected to the perforated plates and the ends of the rotating plates. A first spring is vertically arranged between the two first damping rods, and the two ends of the first spring are respectively fixed to the rotating columns at both ends of the two first damping rods.

[0007] As a preferred embodiment, a hole frame is vertically fixed on the top surface of the rotating plate, and a second damping rod is vertically fixed on the top surface of the rotating plate. A second spring is vertically sleeved on the outside of the second damping rod, and the bottom end of the second spring is fixed on the top surface of the rotating plate.

[0008] As a preferred embodiment, the mounting component includes a sliding plate, which is horizontally slidably mounted in the hole frame, and the bottom surface of the sliding plate is fixedly connected to the top surface of the second damping rod and the second spring.

[0009] As a preferred embodiment, a lifting rod is vertically fixed on the top surface of the slide plate, and the lifting rod slides through the top surface of the hole frame.

[0010] As a preferred embodiment, a pull plate is horizontally fixed on the top surface of the lifting rod, and a mounting plate is horizontally installed above the pull plate.

[0011] As a preferred embodiment, a lifting hole plate is vertically fixed on the top surface of the mounting plate, and the lifting hole plate is used to connect and fix the lifting cable. Lifting cables are fixed at both ends of the bottom surface of the mounting plate.

[0012] As a preferred embodiment, the bottom end of the suspension cable is fixed with a pull pin, and the pull pin is rotatably connected to the end of the perforated plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the top of the mounting component is fixedly assembled with the bottom of the crane cable. Then, when the hook is used to lift goods, the vibration generated during operation causes the lifting plate to rotate on the lifting column of the hook plate frame. The hook plate frame sways left and right, which compresses the extension of the first damping rod and the deformation of the first spring. This filters and absorbs the swaying inertia of the lifted goods. The deformation potential energy of the first spring is offset by the damping force generated by the first damping rod, thereby offsetting and absorbing the swaying inertia of the lifted goods and ensuring the stability of the lifted goods.

[0026] like Figures 1 to 5As shown, a suspension assembly for an electric hook includes a hook body 1, a suspension component 2, and a mounting component 3. The hook body 1 includes a hook frame 11, with a lower hook 12 rotatably connected to the bottom end of the hook frame 11. A hanging column 13 is horizontally inserted and limited through the center of the top surface of the hook frame 11. The suspension component 2 includes a rotating plate 21, which is horizontally positioned above the hook frame 11. A hanging plate 22 is vertically fixed to the bottom surface of the rotating plate 21, and the hanging plate 22 is inserted through the hanging column 13. The mounting component 3 is vertically connected and assembled above the rotating plate 21. Perforated plates 14 are fixed to the top of the vertical ends of both sides of the hook frame 11. Two first damping rods 15 are vertically and symmetrically arranged above the perforated plates 14. Rotating columns 16 are horizontally fixed to the upper and lower ends of the two first damping rods 15, and the rotating columns 16 at both ends of the two first damping rods 15 are rotatably connected to the ends of the perforated plates 14 and the rotating plate 21. A first spring 17 is vertically arranged between the first damping rods 15, and the two ends of the first spring 17 are respectively fixed to the rotating columns 16 at both ends of the two first damping rods 15. In use, the hanging plate 22 on the bottom surface of the rotating plate 21 in the suspension component 2 is inserted into the inside of the hook plate frame 11 of the hook body 1, and then the hanging column 13 is inserted into the hanging plate 22 through the hook plate frame 11. In use, the top end of the mounting component 3 is fixedly assembled with the bottom end of the crane cable. When the lower hook 12 lifts the goods, the vibration generated causes the hanging plate 22 to rotate on the hanging column 13 of the hook plate frame 11, and the hook plate frame 11 sways left and right, squeezing the first damping rod 15 to extend and the first spring 17 to deform, filtering and absorbing the swaying inertia of the lifted goods. The deformation potential energy of the first spring 17 is offset by the damping force generated by the first damping rod 15, thereby offsetting and absorbing the swaying inertia of the lifted goods and ensuring the stability of the lifted goods.

[0027] In one embodiment, such as Figure 3 and 4 As shown, a hole frame 23 is vertically fixed on the top surface of the rotating plate 21, and a second damping rod 24 is vertically fixed on the top surface of the rotating plate 21. A second spring 25 is vertically sleeved on the outside of the second damping rod 24, and the bottom end of the second spring 25 is fixed on the top surface of the rotating plate 21. The mounting component 3 includes a sliding plate 31, which is horizontally slidably installed in the hole frame 23. The bottom surface of the sliding plate 31 is fixedly connected to the top surface of the second damping rod 24 and the second spring 25. When lifting and hoisting goods, the lifting rod 32 is pulled to move vertically on the hole frame 23, which drives the sliding plate 31 to move vertically in the hole frame 23. This causes the second damping rod 24 to extend and the second spring 25 to deform, filtering the swaying of the hoisted goods. The deformation potential energy of the second spring 25 is offset by the damping force generated by the second damping rod 24, improving the effectiveness of hoisting goods.

[0028] In one embodiment, such as Figure 4 and 5As shown, a lifting rod 32 is vertically fixed on the top surface of the sliding plate 31, and the lifting rod 32 slides through the top surface of the perforated frame 23. A pull plate 33 is horizontally fixed on the top surface of the lifting rod 32, and an installation plate 34 is horizontally installed above the pull plate 33. A lifting plate is vertically fixed on the top surface of the installation plate 34, and the lifting plate is used to connect and fix the lifting cable. Lifting cables 35 are fixed at both ends of the bottom surface of the installation plate 34. A pull pin 36 is fixed at the bottom end of the lifting cable 35, and the pull pin 36 is rotatably connected to the end of the pull plate 33. In use, the lifting plate on the installation plate 34 is used to connect and fix the lifting cable, and at the same time, the bottom end of the lifting cable 35 on the bottom surface of the installation plate 34 is rotatably connected to the end of the pull plate 33. The lifting cable 35 has a distributed lifting force, which facilitates the improvement of the stability of the hoisted goods.

[0029] In this embodiment, during use, the hanging plate 22 on the bottom surface of the transfer plate 21 in the suspension component 2 is inserted into the inside of the hook plate frame 11 of the hook body 1. Then, the hanging column 13 is inserted into the hanging plate 22 through the hook plate frame 11. During use, the top end of the mounting component 3 is fixedly assembled with the bottom end of the crane cable. Then, when the lower hook 12 lifts the goods, the vibration generated causes the hanging plate 22 to rotate on the hanging column 13 of the hook plate frame 11. The hook plate frame 11 sways left and right, compressing the first damping rod 15 to extend and the first spring 17 to deform, filtering and absorbing the swaying inertia of the lifted goods. The deformation potential energy of the first spring 17 is resisted by the damping force generated by the first damping rod 15. The lifting rod 32 moves vertically on the hole frame 23 during lifting, thereby offsetting and absorbing the swaying inertia of the hoisted goods. This causes the sliding plate 31 to move vertically within the hole frame 23, pulling the second damping rod 24 to extend and the second spring 25 to deform, filtering the swaying of the hoisted goods. The deformation potential energy of the second spring 25 is offset by the damping force generated by the second damping rod 24, improving the effectiveness of hoisting. During use, the hoisting hole plate on the mounting plate 34 is used to connect and fix the hoisting cable. At the same time, the bottom end of the hoisting cable 35 on the bottom surface of the mounting plate 34 is rotatably connected to the end of the pull hole plate 33. The hoisting cable 35 disperses the lifting force, which helps to improve the stability of the hoisted goods. The above is a preferred embodiment of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model.
