Description

Technical Field

[0001] This utility model relates to the field of lifting and transportation equipment technology, specifically to a rotatable hook. Background Technology

[0002] A crane is a multi-action machine used for lifting, transporting, and lowering heavy objects. It can vertically lift and horizontally move heavy objects within a certain range. When lifting heavy objects, the crane relies on hooks and ropes to connect the load. During the production of aluminum ingots, electric double-girder cranes are usually used in the milling workshop to lift aluminum ingots. However, due to the lack of automatic rotation of the hooks during the lifting process, workers need to push the aluminum ingots to rotate them when they are lowered for placement. This manual rotation during lifting is inconvenient and poses certain safety hazards. In the milling workshop, each electric double-girder crane lifts aluminum ingots more than 100 times in 8 hours, requiring dedicated personnel to assist in rotating the ingots. This is time-consuming, labor-intensive, and reduces the efficiency of lifting aluminum ingots. Summary of the Invention

[0003] This invention addresses the problems of existing lifting hooks being unable to rotate and the inconvenience of rotating aluminum ingots by providing a rotatable lifting hook. This hook allows for easy rotation and placement of aluminum ingots, reducing the labor intensity of workers, saving time and effort, and improving the efficiency of lifting aluminum ingots.

[0004] To achieve the above objectives, the technical solution of this utility model is: a rotatable hook, including a support base and a pulley mechanism located above the support base. A drive assembly and a counterweight are symmetrically arranged on the top of the support base. Support side plates are also spaced apart on the top of the support base, and the upper ends of the support side plates are connected to the pulley mechanism. The pulley mechanism is used to connect to a crane via a wire rope. The counterweight acts as a counterweight to prevent excessive weight on the side of the support base where the drive assembly is installed, ensuring weight balance on both sides of the support base and thus avoiding affecting the hook's ability to lift aluminum ingots.

[0005] The drive assembly is connected to a rotating assembly, which includes a drive shaft, a hook sleeve, and a U-shaped seat. The drive shaft is rotatably connected to a support base, with its upper end passing through the support base and connected to the hook sleeve. Its lower end is connected to the U-shaped seat, which is movably connected to a hook. The drive assembly rotates the rotating assembly, thus rotating the hook and facilitating the rotation and placement of aluminum ingots.

[0006] Furthermore, the pulley mechanism includes a pulley housing, a pulley shaft, and pulleys. The pulley shaft is fixedly disposed inside the pulley housing, and multiple pulleys are rotatably sleeved on the pulley shaft. A pulley bearing is provided between the pulleys and the pulley shaft. The pulleys are connected to the crane via wire ropes. Through the coordinated action of the pulleys and the wire ropes, the hook can move up and down, thereby completing the lifting operation of the aluminum ingot.

[0007] Furthermore, there are two supporting side plates. The upper end of each supporting side plate extends into the interior of the pulley housing and is rotatably sleeved on the pulley shaft. A limiting baffle connected to the pulley housing is provided on the inner side of each supporting side plate. A fixing seat connected to the support base is provided on the outer side of the lower end of each supporting side plate. The limiting baffle acts as a block to prevent the supporting side plate from moving laterally on the pulley shaft, and the fixing seat can fix the supporting side plate.

[0008] Furthermore, the drive assembly includes a motor and a drive gear. The motor is fixedly mounted on the top of the support base. The output end of the motor passes through the support base and is connected to the drive gear. When the motor is started, it can drive the drive gear to rotate.

[0009] Furthermore, a fixing sleeve is fixedly disposed between the two supporting side plates, and the upper end of the drive shaft passes through the fixing sleeve and is connected to the hook bushing; a thrust bearing is disposed between the hook bushing and the fixing sleeve, and both the bottom of the hook bushing and the top of the fixing sleeve are provided with steps that match the thrust bearing. The steps provide an installation position for the thrust bearing, and the action of the thrust bearing allows the hook bushing and the drive shaft to rotate synchronously, while the fixing sleeve provides support for the hook bushing and the drive shaft.

[0010] Furthermore, a driven gear is fixedly sleeved at the lower end of the drive shaft, and the driven gear meshes with the driving gear. A gear housing is fixedly installed at the bottom of the support base. A guide bearing is provided between the drive shaft and the support base, and a spacer is provided between the guide bearing and the driven gear, with the spacer sleeved on the drive shaft. The driving gear can drive the driven gear to rotate, thereby causing the driven gear to drive the drive shaft to rotate, achieving the effect of rotating the hook, thus facilitating the rotation and placement of aluminum ingots.

[0011] Furthermore, a hook shaft is fixedly installed on the U-shaped seat, and the upper end of the hook is rotatably sleeved on the hook shaft, thereby achieving the purpose of installing the hook on the U-shaped seat through the hook shaft.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] This utility model has a reasonable structure and good performance. The hook can rotate, which facilitates the rotation and placement of aluminum ingots. It replaces the manual method of pushing aluminum ingots to rotate and place them. The hoisted aluminum ingots can be rotated in any direction according to actual needs, which reduces the labor intensity of workers, saves time and effort, ensures the safety of workers, and improves the efficiency of hoisting aluminum ingots.

[0014] The pulley of this utility model pulley mechanism is used to connect to the crane via a wire rope. Through the coordinated action of the pulley and the wire rope, the crane drives the hook to move up and down via the pulley mechanism and rotating components, thereby completing the lifting and moving of the aluminum plate ingot.

[0015] This invention uses a drive assembly to drive a driven gear to rotate, thereby enabling the driven gear to drive the rotating assembly's drive shaft to rotate. The fixed sleeve supports the hook bushing, drive shaft, and thrust bearing. The thrust bearing allows the hook bushing to rotate synchronously with the drive shaft. The rotation of the drive shaft drives the U-shaped seat and hook to rotate synchronously, thus enabling the hook to rotate and facilitating the rotation and placement of aluminum ingots.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1-3As shown in the figure, a rotatable hook includes a support base 7 and a pulley mechanism located above the support base 7. On the top of the support base 7, a drive assembly and a counterweight 10 are symmetrically arranged. On the top of the support base 7, support side plates 5 are also arranged at intervals. The upper ends of the support side plates 5 are connected to the pulley mechanism. In this embodiment, the cross-section of the support base 7 is in a "convex" shape. A through hole for the drive shaft 16 to pass through is opened at the middle position of the support base 7. The drive assembly and the counterweight 10 are symmetrically installed on the top of the support base 7. The counterweight 10 plays a role in counterweight. The purpose is to ensure the weight balance on both sides of the support base 7 and avoid the phenomenon that the side of the support base 7 where the drive assembly is installed is overweight, resulting in the inclination of the support base 7, the drive shaft 16, and the hook 22. The two ends of the support side plates 5 are respectively connected to the pulley mechanism and the support base 7, playing the role of connecting the pulley mechanism and the support base 7.

[0022] The drive assembly is传动连接 with a rotation assembly. The rotation assembly includes a drive shaft 16, a hook bushing 14, and a U-shaped seat 17. The drive shaft 16 is rotatably connected to the support base 7. The upper end of the drive shaft 16 passes through the support base 7 and is connected to the hook bushing 14. The lower end of the drive shaft 16 is connected to the U-shaped seat 17. The U-shaped seat 17 is movably connected to a hook 22. In this embodiment, the hook bushing 14 and the upper end of the drive shaft 16 are fixedly connected by a screw. The drive assembly can drive the drive shaft 16 to rotate inside the support base 7. The drive shaft 16 can带动 the hook bushing 14 and the U-shaped seat 17 to rotate synchronously. The rotation of the U-shaped seat 17带动 the hook 22 to rotate synchronously, so as to实现 the effect of the hook 22 rotating. The rotation of the hook 22 is convenient for the rotational placement of aluminum ingots.

[0023] The pulley mechanism includes a pulley housing 1, a pulley shaft 2, and pulleys 3. The pulley shaft 2 is fixedly arranged inside the pulley housing 1. A plurality of the pulleys 3 are rotatably sleeved on the pulley shaft 2. A pulley bearing 4 is arranged between the pulley 3 and the pulley shaft 2. In this embodiment, both ends of the pulley shaft 2 extend to the outside of the pulley housing 1 and are connected to locking nuts to fixedly install the pulley shaft 2 inside the pulley housing 1 through the action of the locking nuts. The number of pulleys 3 on the pulley shaft 2 is four. Two of the pulleys 3 are fitted and installed in the middle of the pulley shaft 2. The other two pulleys 3 are arranged at intervals with the two pulleys 3 located in the middle of the pulley shaft 2. Each pulley 3 is connected to a crane through a steel wire rope. Through the coordinated action of the four pulleys 3 and the steel wire rope, the hook 22 can be moved up and down to complete the hoisting and moving of the aluminum ingot. A rope hole for the steel wire rope to pass through is opened on the pulley housing 1 to facilitate the steel wire rope to be sleeved on the pulley 3. The pulley 3 is rotatably installed on the pulley shaft 2 through the pulley bearing 4.

[0024] It should be noted that the term "传动连接" in the original text is not accurately translated here as there is no exact equivalent in English. A more appropriate expression like "drivably connected" or "transmission-connected" might be needed depending on the specific context and technical meaning. Also, "带动" is translated as "带动", which might need to be adjusted to a more accurate English term like "drive" or "cause to move" for better clarity.There are two supporting side plates 5. The upper end of each supporting side plate 5 extends into the interior of the pulley housing 1 and is rotatably sleeved on the pulley shaft 2. A limiting baffle 6 connected to the pulley housing 1 is provided on the inner side of each supporting side plate 5. A fixing seat 8 connected to the support base 7 is provided on the outer side of the lower end of each supporting side plate 5. In this embodiment, the bottom of the pulley housing 1 has two openings for the supporting side plates 5 to pass through. There are two limiting baffles 6. The edges of the limiting baffles 6 are bolted to the pulley housing 1. The limiting baffles 6 limit and block the supporting side plates 5, and their purpose is to prevent the supporting side plates 5 from moving laterally on the pulley shaft 2.

[0025] The drive assembly includes a motor 9 and a drive gear 12. The motor 9 is fixedly mounted on the top of the support base 7, and the output end of the motor 9 passes through the support base 7 and is connected to the drive gear 12. In this embodiment, the drive gear 12 is located below the support base 7. When the motor 9 is turned on, the output end of the motor 9 can drive the drive gear 12 to rotate.

[0026] A fixing sleeve 13 is fixedly disposed between the two supporting side plates 5. The upper end of the drive shaft 16 passes through the fixing sleeve 13 and is connected to the hook bushing 14. A thrust bearing 15 is disposed between the hook bushing 14 and the fixing sleeve 13. Both the bottom of the hook bushing 14 and the top of the fixing sleeve 13 are provided with steps that match the thrust bearing 15. In this embodiment, the fixing sleeve 13 supports the hook bushing 14 and the drive shaft 16. The thrust bearing 15 facilitates the synchronous rotation of the hook bushing 14 by the drive shaft 16. The steps provide a position for the installation of the thrust bearing 15.

[0027] A driven gear 18 is fixedly sleeved on the lower end of the drive shaft 16, and the driven gear 18 meshes with the driving gear 12. A gear housing 11 is fixedly installed on the bottom of the support base 7. A guide bearing 19 is provided between the drive shaft 16 and the support base 7, and a spacer 20 is provided between the guide bearing 19 and the driven gear 18. The spacer 20 is sleeved on the drive shaft 16. In this embodiment, when the output end of the motor 9 drives the driving gear 12 to rotate, the driving gear 12 drives the driven gear 18 to rotate synchronously, the driven gear 18 drives the drive shaft 16 to rotate synchronously, and the drive shaft 16 drives the hook bushing 14 and the U-shaped seat 17 to rotate synchronously, so as to achieve the effect of the U-shaped seat 17 driving the hook 22 to rotate. The gear housing 11 plays a protective role for the driving gear 12 and the driven gear 18, and a circular hole for the drive shaft 16 to pass through is opened at the bottom of the gear housing 11.

[0028] A hook shaft 21 is fixedly installed on the U-shaped base 17, and the upper end of the hook 22 is rotatably sleeved on the hook shaft 21. In this embodiment, the hook shaft 21 is used to install the hook 22 on the U-shaped base 17, so that the U-shaped base 17 drives the hook 22 to rotate, which facilitates the rotation and placement of aluminum ingots.

[0029] The working principle of this utility model is as follows: each pulley 3 is connected to the crane via a wire rope. Through the coordinated action of the four pulleys 3 and the wire rope, the hook 22 can move up and down. When lifting aluminum ingots, the hook 22 is used to lift and move the aluminum ingots.

[0030] When the aluminum ingot is lowered for placement, the motor 9 is turned on. The output end of the motor 9 drives the drive gear 12 to rotate, which in turn drives the driven gear 18 to rotate. The driven gear 18 drives the drive shaft 16 to rotate. Through the action of the thrust bearing 15 and the guide bearing 19, the upper and lower ends of the drive shaft 16 drive the hook bushing 14 and the U-shaped seat 17 to rotate, respectively. The U-shaped seat 17 drives the hook 22 to rotate synchronously through the action of the hook shaft 21. The hook 22 can rotate the aluminum ingot in any direction as needed, thus achieving the effect of rotating and placing the aluminum ingot.
