Technical Field

[0001] The invention belongs to the technical field of hooks and relates to a crane hook assembly. Background Art

[0002] As a component of cranes, hooks play a key role in the industrial and construction fields, providing a reliable solution for heavy object handling. Cranes are mechanical equipment used to carry and lift heavy objects, including arms and mechanical systems, and hooks are its key components. They are located at the end of the arm and are connected by ropes or chains. They are used to lift, move and put down various objects stably. Its importance lies in effectively carrying heavy objects, providing safe connections, being suitable for different scenarios, and improving work efficiency.

[0003] A patent with announcement number CN216662225U discloses a hook assembly of a crane, including a fixed box, a pulley is rotatably connected inside the fixed box, a steel rope is sleeved on the outer side of the pulley, a hook body is rotatably connected to the lower surface of the fixed box, a lubrication bin is embedded and connected to the bottom end of the fixed box, a handle is fixedly connected to one side of the lubrication bin, an oiler is fixedly connected to the inside of the fixed box between the lubrication bin and the pulley, and fixing components are screwed on both sides of the fixed box, and a dustproof frame is fixedly connected to the inside of the fixing component. This invention relates to the technical field of hooks. The hook assembly of the crane can clean the surface of the pulley through the dustproof frame to prevent the surface of the pulley from absorbing too much dust. At the same time, the dustproof frame is easy to install and disassemble, so it is convenient to use according to actual needs. The pulley can be oiled through the oiler and the lubrication bin to prevent excessive friction between the pulley and the steel rope. Although the application uses the dustproof frame to clean the surface of the pulley to prevent the surface of the pulley from absorbing too much dust, it does not take into account the problem that the long-term use of the dustproof frame will cause serious wear and tear, and the inconvenience of disassembly will reduce the practicality of the hook. Summary of the invention

DETAILED DESCRIPTION

[0022] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and technical solutions.

[0023] Reference Figure 1-2 , an embodiment of the present invention is provided: a crane hook assembly, the upper surface of the fixed box 1 is fixedly connected to two left-right symmetrical and vertically arranged support plates 2; the two support plates 2 are fixedly connected inside with a fixed shaft 3, and the outer wall of the fixed shaft 3 is rotatably connected with a roller 4; the outer walls of the two support plates 2 are fixedly connected with a stabilizing block 5, the outer walls on both sides of the stabilizing block 5 are fixedly connected with left-right symmetrical hinge seats 6, the inner side walls of the two hinge seats 6 are rotatably connected with handles 7, one side of the outer wall of the handle 7 is fixedly connected with a card block 8, and a reset spring 9 is fixedly connected between the two handles 7; a cleaning component is slidably connected to the stabilizing block 5; the cleaning component includes a plug post 10, the outer wall of the plug post 10 is slidably connected to the upper part of the stabilizing block 5, and the bottom two sides of the plug post 10 are slotted, and when the plug post 10 is in a low position, the top of the card block 8 is engaged in the card slot of the plug post 10; the top of the plug post 10 is rotatably connected with a cleaning roller 11, and the cleaning roller 11 is located between the two plug posts 10;

[0024] Specifically, in the process of lifting goods, the steel cable will drive the roller 4 to rotate. The roller 4 and the cleaning roller 11 are fitted together to achieve the effect of cleaning the dust on the surface of the roller 4. After long-term use, by pressing the handle 7, the reset spring 9 will shrink, so that the block 8 can be easily detached from the inside of the plug 10. Gently move the plug 10, and the cleaning roller 11 can be easily removed, thereby achieving the effect of quick disassembly. It not only improves the cleaning efficiency, but also reduces the maintenance cost. Through simple operation, the user can easily disassemble and replace the cleaning roller 11, extending the service life of the equipment.

[0025] Reference Figure 3 A motor 12 is fixedly connected to one side of the outer wall of the fixed box 1, and a transmission shaft 13 is fixedly connected to the output end of the motor 12; a worm 14 is fixedly connected to the outer wall of the transmission shaft 13, and the outer walls of both ends of the transmission shaft 13 are rotatably connected to the inside of the fixed box 1; a fixed shaft 15 is rotatably connected to the inside of the fixed box 1, and a hook 16 is fixedly connected to the lower surface of the fixed shaft 15; a worm wheel 17 is fixedly connected to the outer wall of the fixed shaft 15, and the worm wheel 17 is meshed with the worm 14; a ratchet 18 is fixedly connected to one end of the transmission shaft 13, and a fixed block 19 is fixedly connected to the outer wall of the fixed box 1, and a ratchet 20 is rotatably connected to the outer wall of the fixed block 19, and the ratchet 20 is meshed with the ratchet 18;

[0026] Specifically, by starting the motor 12, the outer wall worm 14 of the transmission shaft 13 starts to rotate. This rotation drives the worm wheel 17 to rotate at multiple angles, achieving an efficient transmission effect. The ratchet 18 moves synchronously with the transmission shaft 13 to ensure the stability and accuracy of the transmission. At this time, the ratchet 18 and the pawl 20 cooperate with each other. When the hook 16 is subjected to the force of the inertia of the cargo, the pawl 20 will react quickly, and through the bite action with the ratchet 18, effectively prevent the hook 16 from reversing, thereby ensuring the safety and stability of cargo transportation.

[0027] Reference Figure 4 A fixing bolt 21 is provided inside the hook 16, a compression spring 22 is provided on the outer wall of the fixing bolt 21, a buckle 23 is attached to the outer wall of the compression spring 22, and the buckle 23 is attached to the inner wall of the hook 16;

[0028] Specifically, by pressing the buckle 23, the compression spring 22 is contracted, thereby achieving the effect of detaching the buckle 23 from the hook 16. In this process, the force of the compression spring 22 is released, so that the connection between the buckle 23 and the hook 16 becomes loose. At this time, the goods are hung on the hook 16, and then the buckle 23 is released so that the compression spring 22 is no longer subjected to force. When the buckle 23 is no longer subjected to the force of the compression spring 22, the reaction force of the compression spring 22 begins to play a role. This reaction force pushes the buckle 23 to move toward the outer wall, so that it re-engages the outer wall at the front end of the hook 16. In this way, the connection between the buckle 23 and the hook 16 becomes tighter, thereby effectively preventing the falling of the goods.

[0029] Working principle: When the hook needs to be operated, the buckle 23 is pressed to shrink the compression spring 22, thereby achieving the effect of separating the buckle 23 from the hook 16. At this time, the goods are hung on the hook 16 and the buckle 23 is released so that the compression spring 22 is no longer under stress. The reaction force of the compression spring 22 pushes the buckle 23 to engage with the outer wall of the hook 16, thereby achieving the effect of preventing the items from falling. By starting the motor 12, the worm 14 on the outer wall of the transmission shaft 13 rotates, thereby achieving the effect of driving the worm wheel 17 to rotate at multiple angles. The ratchet 18 moves synchronously with the transmission shaft 13, and the ratchet 18 cooperates with the pawl 20 to prevent the hook 16 from reversing due to the inertia of the goods. At this time, when lifting the goods, the steel cable will drive the roller 4 to rotate, and the roller 4 and the cleaning roller 11 rotate in close contact, so as to achieve the effect of cleaning the dust on the surface of the roller 4. After long-term use, the reset spring 9 is contracted by pressing the handle 7, so as to achieve the effect of facilitating the removal of the block 8 from the inside of the plug post 10, and the plug post 10 is gently moved, so as to achieve the effect of facilitating the removal of the cleaning roller 11 for quick disassembly.
