Description

Technical Field

[0001] The utility model relates to the technical field of container spreaders, in particular to a full-functional light integrated container spreader. Background Art

[0002] The special rotary spreader configured for a container crane provides great convenience for container terminal operations. It is widely used in loading operations and container door adjustment operations related to terminal operators, ship operators, and logistics transportation operators, and is widely applied to container cranes at terminals across the country. The special spreader rotary mechanism of the container crane realizes the rotary operation of the spreader by relying on a rotary bearing and a hydraulic system. The connection of the rotary mechanism is realized by the rotary bearing and connecting bolts, and all the weights of the spreader and the load below the rotary mechanism are borne by the rotary bearing and the connecting bolts.

[0003] Currently, when using a container spreader, the container operation environment is complex. During the operation, the upper and lower mechanisms are disengaged due to the failure of the slewing bearing or the fracture of the connecting bolts, resulting in the fall of the spreader and the loaded container, which will cause damage to the goods and pose a safety hazard. Usually, a hydraulic control system is used to control the linkage mechanism to drive the lock head to lock or unlock the container corner fittings, and there may be a phenomenon that the lock head is loose and falls off from the container, which may further cause the container to be loose or even fall, and is not conducive to the lifting operation. Therefore, we designed a full-functional light integrated container spreader to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and to propose a full-functional light integrated container spreader.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

The two rotating discs on the same hanging frame are driven to rotate by a driving assembly. A first lifting ring is installed at the upper end of the spreader main body. A second lifting ring is arranged above the spreader main body. Two stabilizing assemblies are symmetrically arranged in the front - and - back directions on each of the two hanging frames. The free ends of multiple stabilizing assemblies are connected to the second lifting ring. The driving assembly includes rotating rods respectively fixedly connected to the upper ends of the two rotating discs and co - rotating with them. Gears co - rotating with the rotating rods are sleeved on the side walls of the two rotating rods. A rack plate meshing with the two gears is slidably connected in the front - and - back direction on the hanging frame. A driving block is fixedly connected to the side wall of the rack plate. A servo motor is installed at the upper end of the hanging frame. A threaded rod is installed at the end of the output shaft of the servo motor. The threaded rod threadedly penetrates through the driving block. A guiding chute arranged in the front - and - back direction is opened at the upper end of the hanging frame. A guiding slider is slidably connected in the guiding chute. The rack plate is fixedly connected to the upper end of the guiding slider.

[0007] Preferably, the stabilizing assembly includes a threaded column welded to the upper end of the hanging frame. A threaded sleeve is threadedly connected to the threaded column.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0017] Referring to Figures 1 - 4 as shown, a full-functional lightweight integrated container spreader includes a spreader main body 1. A plurality of cavities are penetrated through the spreader main body 1, which can reduce the weight of the spreader main body 1. Hangers 2 are provided on both side walls at the two ends of the spreader main body 1. A plurality of reinforcing screws are connected between the hangers 2 and the spreader main body 1, so that the hangers 2 can be stably installed on the spreader main body 1. Rotating discs 3 are rotatably connected through both hangers 2. Locking buckles 4 are installed at the bottoms of the plurality of rotating discs 3, so that the rotation of the rotating discs 3 can drive the rotation of the locking buckles 4. The locking buckles 4 are inserted into the lock slots on the container, and the rotation of the locking buckles 4 can be locked with the lock slots, and then the container can be lifted. This is the prior art and will not be elaborated here. The two rotating discs 3 on the same hanger 2 are both driven to rotate by a driving assembly; the driving assembly includes rotating rods respectively fixedly connected to the upper ends of the two rotating discs 3 and coaxial with them. Gears 5 coaxial with them are sleeved on the side walls of the two rotating rods. A rack plate 6 meshing with both gears 5 is slidably connected back and forth on the hanger 2. A forward and backward arranged guiding chute is opened at the upper end of the hanger 2. A guiding slider is slidably connected in the guiding chute. The rack plate 6 is fixedly connected to the upper end of the guiding slider. The sliding of the guiding slider in the guiding chute can guide the rack plate 6 and make the rack plate 6 slide stably back and forth. When the rack plate 6 slides, it can make the two gears 5 rotate synchronously under its meshing action. A driving block 7 is fixedly connected to the side wall of the rack plate 6. A servo motor 8 is installed at the upper end of the hanger 2. A threaded rod 9 is installed at the end of the output shaft of the servo motor 8. The threaded rod 9 threadedly penetrates through the driving block 7. The rotation of the servo motor 8 driving the threaded rod 9 can make the driving block 7 drive the rack plate 6 to slide back and forth under its threaded meshing action.

[0018] A first lifting ring 10 is installed at the upper end of the sling main body 1. A second lifting ring 15 is provided above the sling main body 1. Two stabilizing components are symmetrically arranged in the front and rear on each of the two hanging frames 2. The free ends of multiple stabilizing components are all connected to the second lifting ring 15. The stabilizing component includes a threaded column 11 welded to the upper end of the hanging frame 2. A threaded sleeve 12 is threadedly connected to the threaded column 11, which is convenient for installing the threaded sleeve 12 on the threaded column 11 or removing the threaded sleeve 12 from the threaded column 11. A connecting ring 13 is welded to the upper end of the threaded sleeve 12. A steel wire sling 14 is provided on the connecting ring 13. The free end of the steel wire sling 14 is connected to the second lifting ring 15. The centers of the second lifting ring 15 and the sling main body 1 are located on the same vertical straight line. The lifting equipment lifts the second lifting ring 15. Multiple steel wire slings 14 can ensure the balance of the sling, and thus can ensure the stability of the sling during the lifting process.

[0019] When the utility model is in use, the hook on the lifting equipment is connected to the first lifting ring 10 to lift the sling. The hook on the lifting equipment is connected to the second lifting ring 15. The stability of the sling can be ensured through multiple steel wire slings 14, and thus the stability during the lifting of the container can be ensured. Moreover, the first lifting ring 10 and the second lifting ring 15 can act together to play a dual protection role, avoiding the problem that the sling is separated from the lifting equipment and causing the sling and the container to fall. During the lifting process, the lock catch 4 moves downward and extends into the lock groove on the container. The servo motor 8 drives the threaded rod 9 to rotate, and under the action of its thread engagement, the driving block 7 can drive the rack plate 6 to move. Then, under the meshing action of the rack plate 6, the two gears 5 can drive the rotating disc 3 to rotate so that the lock catch 4 rotates 90 degrees to lock with the lock groove. Moreover, the threaded rod 9 and the driving block 7 can be stably locked, and thus the stability of the lock catch 4 can be ensured, which is beneficial to the stable lifting of the container and avoids its detachment. When the steel wire sling 14 is damaged during the long-term lifting work, rotate the threaded sleeve 12 to separate it from the threaded column 11, and the steel wire sling 14 can be disassembled, which is convenient for replacing it and the operation is simple.
