[0018] like Figure 1-5 As shown, this invention is a heavy-duty boom device for ships, including a boom body 1, a feeding assembly 3, a lifting assembly 4, a positioning assembly 5, and a control module 6. The feeding assembly 3 is used to adjust the horizontal position of the positioning assembly 5, and is fixedly connected to the boom body 1. The lifting assembly 4 is used to adjust the vertical position of the positioning assembly 5, and is fixedly connected to the output end of the feeding assembly 3. The positioning assembly 5 is used to position the cargo, and includes a drive mechanism 51 and an actuator 52. The actuator 52 is rotatably connected to both sides of the drive mechanism 51, and the drive mechanism 51 is used to drive the actuator 52 to perform clamping actions. The control module 6 is used to control the start and stop of the motor and hydraulic cylinder, and is fixedly connected to the root 11. The control module 6 is connected to the power source 2, the feeding assembly 3, the lifting assembly 4, and the positioning assembly 5 respectively. The positioning component 5 can be used to assist in positioning the goods when they are lifted, so as to prevent the goods from shaking. The horizontal and vertical positions of the positioning component 5 can be adjusted by the feeding component 3 and the lifting component 4. The position of the positioning component 5 can be adjusted according to the size of the goods, thus improving flexibility.
[0019] like Figure 1 and Figure 2 As shown, the main body 1 of the boom includes a root 11, a connector 12, an extension rod 13, and a pulley 14. The connector 12 is rotatably connected to the root 11, the extension rod 13 is slidably connected to the connector 12, and the pulley 14 is fixedly connected to the extension rod 13.
[0020] A power source 2 is provided on the outside of the main body 1 of the boom. The power source 2 includes a first hydraulic cylinder 21 and a second hydraulic cylinder 22. The bottom end of the first hydraulic cylinder 21 is rotatably connected to the root 11, and the top end of the first hydraulic cylinder 21 is rotatably connected to the connector 12. One end of the second hydraulic cylinder 22 is rotatably connected to the connector 12, and the other end of the second hydraulic cylinder 22 is rotatably connected to the extension rod 13. By activating the first hydraulic cylinder 21, the connecting part 12 and the extension rod 13 can be rotated on the root 11, which can rotate the pulley crane 14 above the goods. Subsequently, the goods are hoisted onto the pulley crane 14 by the sling, and the heavy objects are lifted up and down. By activating the second hydraulic cylinder 22, the extension rod 13 can be extended and retracted, which can be used to transfer the goods.
[0021] like Figure 1 , Figure 3 and Figure 4As shown, the feed assembly 3 includes a fixed plate 31, a third hydraulic cylinder 32, and a guide rod 33. The fixed plate 31 is fixedly connected to the extension rod 13, the third hydraulic cylinder 32 is fixedly connected to the fixed plate 31, and the guide rod 33 is slidably connected to the fixed plate 31.
[0022] The lifting assembly 4 includes a housing 41, a slide rail 42, a drive motor 43, a screw 44, a movable block 45, and a slider 46. The housing 41 is fixedly connected to one end of the third hydraulic cylinder 32 and the second hydraulic cylinder 22. The slide rail 42 is fixedly connected to the inner walls of both sides of the housing 41. The drive motor 43 is fixedly connected to the housing 41. The screw 44 is fixedly connected to the output shaft of the drive motor 43. The movable block 45 is threadedly connected to the screw 44. The slider 46 is fixedly connected to both sides of the movable block 45 and is slidably connected to the slide rail 42. By starting the third hydraulic cylinder 32, the lifting component 4 can be moved horizontally, which in turn drives the positioning component 5 to move horizontally. By starting the drive motor 43, the screw 44 can be rotated, which in turn drives the movable block 45 to move vertically, which in turn drives the positioning component 5 to move vertically, thus adjusting the vertical position of the positioning component 5.
[0023] like Figure 1 , Figure 3 and Figure 5 As shown, the drive mechanism 51 includes a mounting plate 511, an electric push rod 512, a movable plate 513, and a connecting rod 514. The mounting plate 511 is fixedly connected to the movable block 45, the electric push rod 512 is fixedly connected to the mounting plate 511, the movable plate 513 is fixedly connected to the output shaft of the electric push rod 512, and the connecting rod 514 is rotatably connected to both sides of the movable plate 513.
[0024] The actuator 52 includes a fixed shaft 521, a positioning rod 522, and a pressure sensor 523. The fixed shaft 521 is fixedly connected to both sides of the mounting plate 511. The positioning rod 522 is rotatably connected to the fixed shaft 521. The positioning rod 522 is rotatably connected to the connecting rod 514. The pressure sensor 523 is fixedly connected to the positioning rod 522. By starting the electric push rod 512, the movable plate 513 is moved horizontally, which in turn causes the connecting rods 514 on both sides to pull the positioning rods 522, causing the two positioning rods 522 to rotate on the fixed shaft 521. This allows the two positioning rods 522 to move relative to each other and clamp the goods on both sides, thus positioning the goods and preventing them from shaking.
[0025] Working principle: During use, the goods are lifted by the pulley 14 and slings. Then, the third hydraulic cylinder 32 is started, which, together with the guide rod 33, pushes the lifting component 4 to move horizontally. At the same time, it drives the positioning component 5 to move horizontally, so that the positioning component 5 moves to one side of the goods. Then, the electric push rod 512 is started, which drives the movable plate 513 to move horizontally. This causes the connecting rods 514 on both sides to pull the positioning rods 522, so that the two positioning rods 522 rotate on the fixed shaft 521. The two positioning rods 522 move relative to each other and clamp the goods on both sides to position the goods and prevent them from shaking. In addition, the pressure sensor 523 can detect whether the goods are clamped in place. After the goods are clamped in place, a signal is sent. The control module 6 receives the signal and stops the electric push rod 512. The positioning position can be adjusted according to the size of the goods. By starting the drive motor 43, the screw 44 is rotated, which can drive the movable block 45 to move vertically. At the same time, it can drive the positioning component 5 to move vertically. Adjusting the vertical position of the positioning component 5 can facilitate the positioning of goods of different sizes. In addition, when the movable block 45 moves, it can drive the slider 46 to slide on the slide rail 42, thereby increasing stability.
