DETAILED DESCRIPTION

[0022] The specific implementation of the utility model is further explained below in combination with the drawings and technical solutions.

[0023] REFERENCE Figures 1-2The utility model provides an embodiment: a crane hook assembly, two left and right symmetry, vertical arrangement's support board 2 are connected to the fixed box 1 upper surface fixedly, two The inside fixed connection of support board 2 all has fixed shaft no. 3, the outer wall rotation of fixed shaft no. 3 4 is connected with the gyro wheel, two The outer wall of support board 2 all is fixedly connected with stabilizing block 5, the outer wall fixed connection of stabilizing block 5 both sides is left and right symmetry's hinged seat 6, two The inner wall rotation of hinged seat 6 all is connected with handle 7, the outer wall one side fixed connection of handle 7 has the clamping block 8, two Handle 7 between fixed connection has return spring 9, the stabilizing block 5 on sliding connection has cleaning assembly, and cleaning assembly includes the column 10, the outer wall sliding connection of column 10 is in stabilizing block 5 upper portion, and the bottom both sides clamping groove of column 10, when column 10 is in low position, the top end clamping of clamping block 8 is in column 10 clamping groove, the top rotation of column 10 is connected with cleaning roller 11, and cleaning roller 11 is located between two Column 10,

[0024] Specifically, in the process of lifting goods, the steel cable drives the gyro wheel 4 to rotate. By the fit of the gyro wheel 4 and the cleaning roller 11, the surface dust of the gyro wheel 4 is cleaned. After a long time of use, the clamping block 8 can be easily separated from the inside of the column 10 by pressing the handle 7, and the return spring 9 is contracted. Gently push the column 10, and the cleaning roller 11 can be conveniently removed, so that the effect of quick disassembly is realized. Not only the cleaning efficiency is improved, but also the maintenance cost is reduced. Through simple operation, the user can easily disassemble and replace the cleaning roller 11, and the service life of the equipment is prolonged.

[0025] Referring to Figure 3 The outer wall one side fixed connection of fixed box 1 has motor 12, and the output end fixed connection of motor 12 has transmission shaft 13; the outer wall fixed connection of transmission shaft 13 has worm 14, and the outer wall rotation of transmission shaft 13 both ends is connected in fixed box 1 inside;Fixed shaft no. 2 15 is rotationally connected in the inside of fixed box 1, and the lower surface fixed connection of fixed shaft no. 2 15 has hook 16;The outer wall fixed connection of fixed shaft no. 2 15 has worm wheel 17, and worm wheel 17 is meshed with worm 14;The one end fixed connection of transmission shaft 13 has ratchet wheel 18, and the outer wall fixed connection of fixed box 1 has fixed block 19, and the outer wall rotation of fixed block 19 is connected with pawl 20, and pawl 20 is meshed with ratchet wheel 18;

[0026] Specifically, by starting the motor 12, the outer wall of the transmission shaft 13 worm 14 begins to rotate. This rotation drives the worm gear 17 to rotate at multiple angles, achieving efficient transmission effect. The ratchet 18 moves synchronously with the transmission shaft 13, ensuring 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 goods, the pawl 20 will quickly react, effectively preventing the hook 16 from reversing, thereby ensuring the safety and stability of the goods transportation.

[0027] Referring to Figure 4 , the hook 16 is provided with a fixed bolt 21, the outer wall of the fixed bolt 21 is provided with a compression spring 22, the outer wall of the compression spring 22 is attached with a buckle 23, 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 separating the buckle 23 from the hook 16. In this process, the force of the compression spring 22 is released, making the connection between the buckle 23 and the hook 16 loose. At this time, the goods are hung on the hook 16, and then the buckle 23 is loosened, so that the compression spring 22 is no longer stressed. When the buckle 23 is no longer stressed by the compression spring 22, the counterforce of the compression spring 22 begins to act. This counterforce pushes the buckle 23 to move outward, making it re-engage with the outer wall of the hook 16. In this way, the connection between the buckle 23 and the hook 16 becomes more secure, thereby effectively preventing the falling of the goods.

[0029] Working principle: when the hook needs to be operated, press the buckle 23 to make the compression spring 22 contract, 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 then the buckle 23 is loosened, so that the compression spring 22 is no longer stressed. The counterforce 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 goods 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 gear 17 to rotate at multiple angles. By the synchronous movement of the ratchet 18 with the transmission shaft 13, and the cooperation between the ratchet 18 and the pawl 20, the effect of preventing the hook 16 from reversing due to the inertia of the goods is achieved. At this time, the steel cable will drive the roller 4 to rotate when lifting the goods, and the roller 4 will rotate in contact with the cleaning roller 11, thereby achieving the effect of cleaning the dust on the surface of the roller 4. After a long period of use, press the handle 7 to make the return spring 9 contract, thereby achieving the effect of facilitating the separation of the clamping block 8 from the inside of the insertion column 10. Gently push the insertion column 10, thereby achieving the effect of facilitating the removal of the cleaning roller 11 for quick disassembly.
