Description

Technical Field

[0001] This invention relates to the field of tilting spreaders, and more particularly to a container tilting spreader for port cranes. Background Technology

[0002] Container tilting spreaders for port cranes are specialized spreader attachments integrated into quay container cranes or rubber-tired gantry cranes. During container handling, they utilize their hydraulic or electric drive systems to smoothly and controllably tilt containers from a horizontal to an inclined position. This function primarily serves the needs of bottom inspection, repair, deep cleaning of containers, and efficient unloading of bulk cargo in specific loading and unloading processes. It significantly enhances the port's operational capabilities and efficiency in comprehensive container maintenance and special cargo handling, making it an important functional piece of equipment in modern smart port logistics systems. Existing container tilting spreaders are mainly designed for cubic containers.

[0003] Existing container tilting spreaders typically secure the top of the container using connectors such as hooks, and then lift it using cranes. This method cannot control the lifting angle of the container. For square containers carrying sand or tubular containers carrying liquids, the containers sway under the influence of wind during lifting, which can easily lead to collisions between adjacent containers and damage to the container. For containers whose center of gravity is not in the center, traditional lifting rope mechanisms can cause the container to tilt and rise due to uneven mass distribution, resulting in internal damage. Summary of the Invention

[0011] Preferably, the adjusting clamping mechanism includes four fourth placement slots equally spaced on the side of the main body plate. The main body plate is fixedly connected to the four fourth placement slots with second electric telescopic rods. The telescopic ends of the four second electric telescopic rods are fixedly connected to the fixing plates, and the inner surfaces of the four fixing plates are flexible structures.

[0012] Preferably, each of the four fixing plates has a limiting groove on its inner side. A second motor is fixedly connected to each fixing plate in the limiting groove. A threaded rod is fixedly connected to the drive shaft end of each of the second motors. Each of the four fixing plates has a limiting body slidably connected in the limiting groove. The threaded rod is threadedly engaged with the limiting body. Each of the four limiting bodies has a third slot on its inner side. A third electric telescopic rod is fixedly connected to each of the four limiting bodies in the third slot. A top plate is fixedly connected to the telescopic end of each of the four third electric telescopic rods. A wear-resistant layer is provided on the side of each of the four top plates.

[0013] Preferably, the lower ends of the four fixing plates are each provided with a third placement groove. A fifth electric telescopic rod is fixedly connected to each fixing plate in the third placement groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The crane moves the main body plate downwards, bringing its lower end close to the upper end of the container. Then, the four second electric telescopic rods retract, bringing the wear-resistant layer inside the fixing plate into close contact with the container's side. Because the wear-resistant layer is flexible and the fixing plates are arranged at equal angles, the device can clamp and fix square and cylindrical containers. Next, the third electric telescopic rod extends, and the four third electric telescopic rods respectively drive the top plate to fix the container's side. Then, the second motor starts, driving the threaded rod to rotate. The threaded rod, in conjunction with the threaded rod, drives the limiting body upwards, thereby moving the container upwards. Then, the four fourth electric telescopic rods extend, and the four fourth electric telescopic rods respectively drive the fixing body to rotate to a horizontal angle. Then, the four third motors respectively drive the fixing body to rotate below the container. Finally, the fifth electric telescopic rod retracts, and four pressure sensors support and limit the container, thus achieving automatic clamping of square and cylindrical containers.

[0017] During the movement, the wind in the air will cause the container to sway. At this time, four pressure sensors will detect the center of gravity of the container. When the center of gravity of the container shifts from the center due to swaying or uneven loading, the value of the pressure sensor is transmitted to the first electric telescopic rod through the controller. The two first electric telescopic rods extend and retract, and at the same time, the first motor starts. The first motor drives the second connecting plate to rotate, thereby rotating the container to a horizontal position. This ensures that the center of the container is always at the center line during the upward movement, preventing the container from tilting and improving the safety of the device.

[0027] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0028] Please see Figures 1-8 A container tilting spreader for a port crane includes a main plate 1, wherein a rotating connection mechanism 2 for adjusting the angle of the main plate 1 is provided at the upper end of the main plate 1.

[0029] The rotating connection mechanism 2 includes a second slot 217 formed on the upper end of the main body plate 1. The main body plate 1 has a first placement slot 211 and a first slot 214 communicating with the second slot 217. A first motor 210 is fixedly connected to the main body plate 1 in the first placement slot 211. A first rotating plate 215 is fixedly connected to the drive shaft end of the first motor 210. The first rotating plate 215 is rotatably engaged with the first slot 214. A connecting post 218 is fixedly connected to the upper end of the first rotating plate 215. A second connecting plate 216 is fixedly connected to the upper end of the connecting post 218.

[0030] The connecting column 218 is rotatably engaged with the second slot 217. The upper end of the second connecting plate 216 is fixedly connected to the second rotating body 29. The upper end of the second rotating body 29 has an arc-shaped structure and a rotating slot is provided at the upper end of the second rotating body 29. The second rotating body 29 is rotatably connected to the first rotating body 28 in the rotating slot. The upper end of the first rotating body 28 is fixedly connected to the connecting body 21.

[0031] The upper end of the connector 21 is fixedly connected to a bolt mechanism that connects to the crane hoisting rope.

[0032] The lower end of the connector 21 is provided with two symmetrically arranged first guide grooves 24. The connector 21 is slidably connected to guide bodies 27 in the first guide grooves 24. The two ends of the second connecting plate 216 are respectively fixedly connected to first connecting plates 23. The upper ends of the two first connecting plates 23 are respectively fixedly connected to first electric telescopic rods 22. The telescopic ends of the two first electric telescopic rods 22 are respectively rotatably engaged with the guide bodies 27.

[0033] The connecting body 21 is symmetrically provided with second guide grooves 25 on the side of the first guide groove 24, and the two guide bodies 27 are respectively fixedly connected with first guide blocks 26 that slide in cooperation with the second guide grooves 25.

[0035] Specifically, the value of the pressure sensor 320 is transmitted to the first electric telescopic rod 22 through the controller. The two first electric telescopic rods 22 extend and retract. At the same time, the first motor 210 starts and drives the second connecting plate 216 to rotate, so that the center of the container is always at the center line during the upward process, preventing the container from tilting.

[0036] The side of the main plate 1 is connected to an adjustable clamping mechanism 3 for clamping square and cylindrical containers.

[0037] The adjusting clamping mechanism 3 includes four fourth placement slots 34 opened at equal angles on the side of the main body plate 1. The main body plate 1 is fixedly connected to the four fourth placement slots 34 respectively. The telescopic ends of the four second electric telescopic rods 31 are fixedly connected to the fixing plates 32 respectively. The inner sides of the four fixing plates 32 are flexible structures.

[0038] Each of the four fixing plates 32 has a limiting groove 35 on its inner side. A second motor 36 is fixedly connected to each fixing plate 32 in the limiting groove 35. A threaded rod 37 is fixedly connected to the drive shaft end of each of the second motors 36. Each of the four fixing plates 32 has a limiting body 38 slidably connected in the limiting groove 35. The threaded rod 37 is threadedly engaged with the limiting body 38. Each of the four limiting bodies 38 has a third slot 310 on its inner side. Each of the four limiting bodies 38 has a third electric telescopic rod 39 fixedly connected in the third slot 310. A top plate 311 is fixedly connected to the telescopic end of each of the four third electric telescopic rods 39. A wear-resistant layer is provided on the side of each of the four top plates 311.

[0039] Each of the four fixed plates 32 has a third placement groove 33 at its lower end. A fifth electric telescopic rod 323 is fixedly connected to each of the fixed plates 32 in the third placement groove 33. A third motor 322 is fixedly connected to the telescopic ends of each of the four fifth electric telescopic rods 323. A support body 321 is fixedly connected to the drive shaft ends of each of the four third motors 322. A fourth slot 312 is opened on the inner side of each of the four support bodies 321. A fourth electric telescopic rod 313 is rotatably connected to each of the four support bodies 321 in the fourth slot 312. A rotating rod 315 is fixedly connected to each of the four support bodies 321 in the fourth slot 312. A fixed body 314 is provided in each of the four fixed plates 32. A rotating hole 316 is opened through the side of each of the four fixed bodies 314. The four rotating holes 316 are rotatably engaged with the rotating rod 315.

[0040] Each of the four fixed bodies 314 has a third guide groove 318 at its upper end. Each of the four fixed bodies 314 has a sliding block 319 slidably connected in the third guide groove 318. Each of the four sliding blocks 319 is rotatably engaged with the fourth electric telescopic rod 313. Each of the four fixed bodies 314 has a pressure sensor 320 fixedly connected at its upper end. Each of the four pressure sensors 320 is connected to the controller via wires. Each of the four support bodies 321 has a stop plate 317 fixedly connected inside its interior.

[0041] Specifically, the crane moves the main body plate 1 downward, so that the lower end of the main body plate 1 is close to the upper end of the container. Then, the four second electric telescopic rods 31 retract, so that the wear-resistant layer on the inner side of the fixing plate 32 is in close contact with the side of the container. Since the wear-resistant layer is a flexible structure and the fixing plates 32 are arranged at equal angles, the device can clamp and fix square and cylindrical containers. Then, the third electric telescopic rod 39 extends, and the four third electric telescopic rods 39 respectively drive the top plate 311 to fix the side of the container.

[0042] In use, the bolt connection mechanism at the upper end of the connector 21 is fixed to the crane's lifting rope. Then, the crane moves the device above the container. Next, the four second electric telescopic rods 31 extend, causing the fixing plates 32 to move in four directions. The monitor 213 detects the relative position between the container and the main plate 1, thus moving the fixing plates 32 to the side of the container. The crane then moves the main plate 1 downwards, bringing its lower end close to the upper end of the container. Finally, the four second electric telescopic rods 31 retract, ensuring the wear-resistant layer inside the fixing plates 32 is in close contact with the side of the container. Because the wear-resistant layer is a flexible structure and the fixing plates 32 are arranged at equal angles, the device can handle both square and cylindrical containers. The container is clamped and fixed. Then, the third electric telescopic rod 39 extends, and the four third electric telescopic rods 39 respectively drive the top plate 311 to fix the side of the container. Then, the second motor 36 starts and drives the threaded rod 37 to rotate. The threaded rod 37, in turn, drives the limiting body 38 to move upward, thereby moving the container upward. Then, the four fourth electric telescopic rods 313 extend, and the four fourth electric telescopic rods 313 respectively drive the fixing body 314 to rotate to a horizontal angle. Then, the four third motors 322 respectively drive the fixing body 314 to rotate below the container. The fifth electric telescopic rod 323 retracts, and the container is supported and limited by the four pressure sensors 320, thereby realizing automatic clamping of square and cylindrical containers.

[0043] After the rotating connecting mechanism 2 clamps the container, the crane moves the container upward. During the movement, the wind in the air will cause the container to sway. At this time, the four pressure sensors 320 will detect the center of gravity of the container. When the center of gravity of the container shifts from the center due to swaying or uneven loading, the value of the pressure sensor 320 is transmitted to the first electric telescopic rod 22 through the controller. The two first electric telescopic rods 22 extend and retract. At the same time, the first motor 210 starts and drives the second connecting plate 216 to rotate, so that the center of the container is always at the center line during the upward process, preventing the container from tilting and improving the safety of the device.

[0044] The foregoing has shown and described 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 to the above embodiments.
