Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a hoisting equipment for loading and unloading containers in ports. Background Technology

[0002] Port container handling equipment is an indispensable part of modern port operations, primarily used for the efficient and safe loading and unloading of container ships. This type of equipment includes various types, such as quay cranes, rubber-tired gantry cranes, and rail-mounted gantry cranes. Quay cranes are typically installed at the edge of the quay, directly responsible for unloading containers from or loading them onto ships. They feature long cantilever arms and high lifting capacity, adapting to the operational needs of large container ships. Rubber-tired gantry cranes are mainly used for handling and stacking containers within the yard; due to their tire drive, they offer high mobility. Rail-mounted gantry cranes travel on rails and are suitable for large-scale, high-density container stacking operations, effectively improving yard utilization.

[0003] In port container handling operations, even slight swaying during the suspension process often prevents containers from being quickly and accurately unloaded into their designated positions in the cargo hold. Due to the long cantilever design of quay cranes, they are susceptible to various factors such as wind and mechanical operation when lifting and moving heavy objects, causing unstable swaying of containers. This swaying not only affects loading and unloading efficiency but may also pose a safety threat and increase the risk of cargo damage. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a hoisting equipment for loading and unloading containers in ports.

[0005] A hoisting device for loading and unloading containers in a port includes a hoist, a fixed frame, hydraulic cylinders, connecting plates, a rotating shaft, a guide plate, a first motor, and radar. The hoist has two cantilever arms symmetrically mounted on its left and right sides. A fixed frame is connected to the side of the hoist's front and rear cantilever arms furthest from each other. A hydraulic cylinder is installed inside each fixed frame. A connecting plate is connected to the piston rod of each hydraulic cylinder. A rotating shaft is rotatably connected to the side of each connecting plate furthest from the hydraulic cylinder. A guide plate is connected to the rotating shaft. Each connecting plate has a through hole for the guide plate to rotate. A first motor is mounted on the connecting plate, and the output shaft of the first motor is fixedly connected to the rotating shaft. Radar is connected between the left and right cantilever arms of the hoist.

[0008] In a preferred embodiment of this utility model, it further includes a hinge frame and a second motor. The hinge frame is hingedly connected inside the fixed frame, and the hinge frame is fixedly connected to the hydraulic cylinder.

[0009] In a preferred embodiment of the present invention, rollers are also included, with rollers installed on the sides of the front and rear guide plates that are far apart from each other.

[0010] In a preferred embodiment of the present invention, the invention further includes a fixed seat, a sliding rod, and an elastic element. The fixed seat is connected to the side of the front and rear guide plates that are far apart from each other. The sliding rod is slidably connected to the fixed seat.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0019] A type of hoisting equipment for loading and unloading containers at a port, such as Figures 1-5 As shown, the system includes a hoist 1, a fixed frame 2, a hydraulic cylinder 3, a connecting plate 4, a rotating shaft 5, a guide plate 6, a first motor 7, a radar 11, a stop block 8, a honeycomb buffer plate 61, a hinge frame 9, a second motor 10, rollers 12, a fixed seat 13, a slide bar 14, and an elastic element 15. The hoist 1 has two cantilever arms symmetrically mounted on its left and right sides. A fixed frame 2 is fixedly connected to the side of the front and rear cantilever arms of the hoist 1 that is furthest from each other. A hydraulic cylinder 3 is installed inside the fixed frame 2. A connecting plate 4 is fixedly connected to the piston rod of each hydraulic cylinder 3. A rotating shaft 5 is rotatably connected to the side of the connecting plate 4 furthest from the hydraulic cylinder 3. A guide plate 6 is fixedly connected to the rotating shaft 5. Each connecting plate 4 has a through hole for the guide plate 6 to rotate. A first motor 7 is mounted on the connecting plate 4. The output shaft of the first motor 7 is fixedly connected to the rotating shaft 5. A radar 11 is fixedly connected between the left and right cantilever arms of the hoist 1. A stop block is fixedly connected to the through hole of the connecting plate 4. 8. A honeycomb-shaped buffer plate 61 is fixedly connected inside the guide plate 6. The space between the honeycomb-shaped buffer plate 61 and the guide plate 6 is filled with Newtonian fluid, which can absorb the impact force generated by the collision between the guide plate 6 and the limiting block of the cargo hold wall. When the guide plate 6 collides with the limiting block of the cargo hold wall, the Newtonian fluid can further increase the collision bearing capacity of the guide plate 6. A hinge frame 9 is hingedly connected inside the fixed frame 2. The hinge frame 9 is fixedly connected to the hydraulic cylinder 3. A second motor 10 is installed inside the fixed frame 2. The output shaft of the second motor 10 is fixedly connected to the hinge frame 9. Rollers 12 are installed on the side of the front and rear guide plates 6 that are far apart from each other. A fixed seat 13 is fixedly connected to the side of the front and rear guide plates 6 that is far apart from each other. A sliding rod 14 is slidably connected inside the fixed seat 13. The sliding rod 14 is fixedly connected to the bracket of the roller 12. An elastic element 15 is fixedly connected between the sliding rod 14 and the fixed seat 13. The elastic element 15 is set as a helical spring.

[0020] Initially, the front and rear connecting plates 4 are far apart and perpendicular to the cantilever of the crane 1. The guide plates 6 are parallel to the connecting plates 4. When the crane 1 lifts the container, the cantilever of the crane 1 clamps and fixes the container, and then the container is transferred to the designated position in the cargo hold for unloading. The radar 11 detects the vertical distance between the container and the designated position. When the vertical distance is within the designated distance range, the container is ready to be unloaded. During the unloading process, the first motor 7 drives the rotating shaft 5 to rotate, causing the sides of the front and rear guide plates 6 that are close to each other to rotate closer together, thus making the guide plates 6 rotate in an inclined state. When the crane 1 sways, it roughly aligns the container with the limiting block on the cargo hold wall. The crane 1 then moves the container downwards into the cargo hold. When the rollers 12 on the front or rear guide plates 6 abut against the limiting block on the cargo hold wall, the guide plates 6 are squeezed and reversed. The hydraulic cylinder 3 drives the connecting plate 4, which is in contact with the limiting block on the cargo hold wall, to move closer to the crane 1. Under the action of the connecting plate 4 and the hydraulic cylinder 3, the crane 1 is supported during swaying, thus quickly eliminating the swaying and enabling more accurate unloading of the container into the designated position in the cargo hold. This reduces the need for readjustment, minimizes safety hazards, and also reduces... To expedite container loading and unloading and improve port efficiency, the crane 1 stops swaying. Hydraulic cylinder 3 drives connecting plates 4, which are not in contact with the limit blocks of the cargo hold wall, to move closer to the crane 1. At this point, the crane 1 is in a stable vertical position, and all rollers 12 on the guide plates 6 are against the limit blocks of the cargo hold wall. The crane 1 continues to move the container downwards along the limit blocks of the cargo hold wall until the designated position. The rollers 12 rotate along the limit blocks of the cargo hold wall, and then hydraulic cylinder 3 drives all connecting plates 4 to move away from the crane 1. Finally, the crane 1's cantilever slacks... The container is opened, thus completing the unloading process. The roller 12 makes the unloading process smoother. When the swing amplitude of the crane 1 is large, the guide plate 6 may collide with the limit block of the cargo hold wall. The stop block 8 can limit the rotation angle of the guide plate 6 to ensure that the roller 12 can contact the limit block of the cargo hold wall. When a collision occurs, the connecting plate 4 may drive the hydraulic cylinder 3 to rotate along the hinge frame 9. The second motor 10 can reverse the hydraulic cylinder 3 to ensure that the connecting plate 4 is perpendicular to the crane 1. The elastic element 15 can buffer the roller 12 to avoid damage caused by the collision between the guide plate 6 and the limit block of the cargo hold wall.
