[0002] A grab bucket is a special tool for a crane to grab dry bulk goods. It consists of two or more openable and closable bucket-shaped jaw plates that together form a material-containing space. When loading, the jaw plates are closed in the material pile, and the material is grabbed into the material-containing space. When unloading, the jaw plates are opened in a suspended state above the material pile, and the material falls on the material pile. The opening and closing of the jaw plates are generally controlled by the steel wire rope of the crane's hoisting mechanism. Grab bucket operation involves no heavy physical labor, can achieve high loading and unloading efficiency, and ensure safety. It is the main dry bulk goods loading and unloading tool in ports.

[0003] During the loading and unloading operation, the bucket tip of the grab bucket of the steel grab machine wears relatively fast. When it wears to a certain extent, it must be repaired. However, due to the inflexible structural design of the bucket tip and insufficient wear resistance, the repair time is long, the repair effect is poor, and it is easy to cause the grab bucket to leak, affecting the loading and unloading quality. In severe cases, the entire grab bucket may be scrapped.

[0004] Therefore, a multi-petal grab bucket with a detachable bucket tip is proposed to upgrade and transform on the basis of the device to solve these deficiencies. Content of the Utility Model

[0026] Such as Figures 1 to 5As shown in the figure, a multi-petal grab bucket with a detachable bucket tip includes a grab bucket body 1. A reinforcing rod 10 is fixedly connected to the outer end of the grab bucket body 1. An installation block 190 is slidably connected to the lower end of the reinforcing rod 10. A concave block 12 is rotatably connected to the outer end of the reinforcing rod 10. A first gear 13 is fixedly installed at one end of the concave block 12. A second gear 14 is meshed with the outer end of the first gear 13. A threaded rod 15 is fixedly installed at the outer end of the second gear 14. A threaded plate 192 is threadedly connected to the outer end of the threaded rod 15. An inclined groove 19 is formed in the outer end of the threaded plate 192. A sliding block 16 is slidably connected to the surface of the inclined groove 19. A clamping rod 17 is fixedly installed at one end of the sliding block 16. A fixing groove 191 for the end of the clamping rod 17 to be clamped is formed in the outer end of the installation block 190. A first spring 18 is fixedly installed at the outer end of the clamping rod 17. One end of the first spring 18 is fixedly installed on the inner wall of the reinforcing rod 10. A grab bucket tip 11 is fixedly connected to one end of the installation block 190. A disassembly mechanism 2 is arranged inside the reinforcing rod 10. Specifically, by inserting a tool into the concave block 12 and rotating it, the first gear 13 drives the threaded rod 15 at the outer end of the second gear 14 to rotate, causing the threaded plate 192 to move upward, the inclined groove 19 to squeeze and drive the sliding block 16 to move outward, and the clamping rod 17 to disengage from the fixing groove 191 at the outer end of the installation block 190, facilitating the separation of the installation block 190 from the reinforcing rod and the disassembly of the grab bucket tip 11. Conversely, the grab bucket tip 11 can be installed.

[0027] As Figure 1 , Figure 2 and Figure 3 shown, a stabilizing block 25 is fixedly connected to one end of the grab bucket tip 11. The outer end of the stabilizing block 25 is slidably connected to the inner wall of the reinforcing rod 10. The disassembly mechanism 2 includes a sliding rod 22. The sliding rod 22 is slidably connected to the inner wall of the reinforcing rod 10. A push plate 23 is fixedly installed at one end of the sliding rod 22. A second spring 26 is fixedly installed at the outer end of the push plate 23. One end of the second spring 26 is fixedly installed on the inner wall of the reinforcing rod 10. A receiving block 24 is fixedly connected to one end of the stabilizing block 25. The outer end of the receiving block 24 abuts against the outer end of the push plate 23. Specifically, due to the action of the second spring 26, the push plate 23 exerts a thrust on the stabilizing block 25, facilitating the easy separation of the grab bucket tip 11 from the reinforcing rod 10. Or, by using an external force to strike the grab bucket tip 11 or the reinforcing rod 10, the grab bucket tip 11 can be separated from the reinforcing rod 10.

[0028] As Figure 2 and Figure 3 shown, a stop block 21 is fixedly installed at the upper end of the sliding rod 22. Specifically, it prevents the sliding rod 22 from detaching from the reinforcing rod 11.

[0029] As Figure 1 , Figure 4 and Figure 5As shown, a limiting block is fixedly connected to the outer end of the threaded plate 192. The outer end of the limiting block is slidably connected to the inner wall of the reinforcing rod 10. A guiding block is fixedly connected to the outer end of the clamping rod 17, and the outer end of the guiding block is fixedly installed on the inner wall of the reinforcing rod 10. Specifically, it facilitates the stable movement of the threaded plate 192 and the stable movement of the clamping rod 17.

[0030] In summary: When the tip of the grab bucket needs to be replaced, insert a tool into the concave block 12 and rotate it, so that the gear one 13 drives the threaded rod 15 at the outer end of the gear two 14 to rotate, causing the threaded plate 192 to move upward, the inclined groove 19 to squeeze and drive the sliding block 16 to move outward, and the clamping rod 17 to disengage from the fixing groove 191 at the outer end of the mounting block 190, facilitating the removal of the mounting block 190 from the reinforcing rod, facilitating the removal of the grab bucket tip 11. Insert the mounting block 190 at the upper end of the new grab bucket tip 11 into the inside of the reinforcing rod 10, and rotate the concave block 12 in the reverse direction, causing the threaded plate 192 to move downward. Through the action of the spring one 18, the sliding block 16 moves inward along with the inclined groove 19, causing the clamping rod 17 to connect with the fixing groove 191, fixing the mounting block 190, and fixing and installing the grab bucket tip 11.

[0031] When it is difficult to remove the grab bucket tip 11 during the disassembly process, through the action of the spring two 26, the push plate 23 pushes the stabilizing block 25, facilitating the pushing of the stabilizing block 25 out of the reinforcing rod 10 and facilitating the disassembly of the grab bucket tip 11. When the grab bucket tip 11 gets stuck during the disassembly process, use an external force to strike the grab bucket tip 11 or the reinforcing rod 10 to loosen the connection between the grab bucket tip 11 and the reinforcing rod 10, causing the grab bucket tip 11 to separate from the reinforcing rod 10.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
