Description

Technical Field

[0001] The utility model relates to the technical field of container hoisting, and more specifically, to a container hoisting device for port freight transportation. Background Art

[0002] Container hoisting for port freight transportation refers to the operation of loading and unloading containers using specialized hoisting equipment at logistics nodes such as seaports, airports, and land ports. This process is a crucial link in international freight transportation as it involves transferring goods from one mode of transportation to another.

[0003] According to the patent application publication number: CN218754502U, a railway freight container spreader is disclosed. The railway freight container spreader includes a rotating pin mechanism for connecting with the container to fix the container; a connecting mechanism is arranged above the rotating pin mechanism, including a connecting rope, a connecting plate, and a buffer member. One end of the connecting rope is connected to the container, and the other end is connected to the buffer member. The connecting plate is provided with a connecting groove for the connecting line to pass through, and the buffer member is installed on the connecting plate; a hoisting mechanism is arranged above the connecting plate. One end of the hoisting mechanism is connected to a hoisting device, and the other end is slidably connected to the buffer member. The connecting line is arranged in the connecting groove, which can prevent the connecting line from moving on the connecting plate, resulting in instability of the rotating pin mechanism and improving the stability of hoisting.

[0004] It can be seen that the existing hoisting equipment focuses on avoiding the shaking of the connecting line during hoisting. Although it improves the stability during hoisting to a certain extent, since most of the existing hoisting equipment fixes the upper end of the container, and the container has a certain weight after being loaded with goods, simply fixing the upper part of the container results in a poor fixing effect on the container and is also prone to the situation of the container falling downward, there are some safety hazards.

[0025] Embodiment, please refer to Figures 1 to 4As shown in the figure, this embodiment provides a container hoisting device for port freight, including a pair of connected adjusting rods 1. Chutes are provided on the lower sides of the pair of adjusting rods 1. Two opposite side plates 4 are respectively slidably connected to both ends of the chutes. The sliding of the side plates 4 in the chutes can adjust containers of different sizes, improving the wide applicability of the device. At the same time, a bidirectional lead screw 2 is rotatably arranged in each of the two chutes. The two bidirectional lead screws 2 are connected by a transmission member 3. The transmission member 3 is composed of two pulley wheels respectively connected to one end of the bidirectional lead screw 2 and a belt sleeved on the pulley wheels, and the transmission member 3 is driven by a motor. Since both ends of the two bidirectional lead screws 2 are threadedly connected to the two side plates 4 respectively, when the bidirectional lead screw 2 rotates, the two side plates 4 move automatically, and the side plates 4 are used to accurately find the position of the container, so as to quickly fix the container.

[0026] Steel wire ropes 16 are connected to the upper sides of the two side plates 4. One end of the steel wire rope 16 is connected to a lifting ring 17, and the lifting ring 17 is connected to a crane or other hoisting equipment to realize the hoisting of the container.

[0027] In addition, symmetric fixing blocks 5 are arranged on the inner sides of the side plates 4, and the fixing blocks 5 are used to fix the upper side of the container.

[0028] Furthermore, sliding rails 6 are symmetrically arranged on the lower sides of the two side plates 4. A fixing component is slidably connected in the symmetric sliding rails 6, and the fixing component moves downward according to the height of the container to fix the bottom of the container.

[0029] Specifically, the fixing component includes a fixing block 8 slidably arranged in a pair of sliding rails 6. The fixing block 8 is threadedly connected to a moving lead screw 7 rotatably arranged in the sliding rail 6, and the moving lead screw 7 is driven by a motor. Therefore, when the moving lead screw 7 rotates, the fixing block 8 adjusts its fixing position to meet the requirement of fixing the lower side of the container.

[0030] Among them, a cross plate 9 is connected between the two fixing blocks 8. Cylinders 15 are installed at both ends of the cross plate 9. The piston ends of the cylinders 15 are connected to a falling prevention plate 10. The falling prevention plate 10 is located above the cross plate 9. The cylinder 15 pushes the falling prevention plate 10 out of the cross plate 9, so that the falling prevention plate 10 is located at the bottom of the lifted container to support the bottom of the container and prevent the container from falling.

[0031] Sliding holes 13 are opened at the parts of the cross plate 9 near both ends. A support block 11 is slidably connected in the sliding holes 13. The support block 11 is connected to one side of the falling prevention plate 10. The support block 11 can move along with the movement of the falling prevention plate 10 to support the falling prevention plate 10 and improve the supporting effect of the falling prevention plate 10.

[0032] A protrusion 12 is provided on the upper side of the support block 11. The protrusion 12 is in contact with the lower side of the anti-falling plate 10. A notch 14 is formed at one end of the sliding hole 13. When the support block 11 resets with the anti-falling plate 10, the protrusion 12 can be located within the notch 14, and the notch 14 receives the protrusion 12.

[0033] When the utility model is used in a container hoisting device for port cargo transportation, during specific use, by rotating the bidirectional lead screw 2, the two side plates 4 can be adjusted according to the size of the container, facilitating the fixing of the upper end of the container by the first fixing block 5. At the same time, as the moving lead screw 7 rotates, the second fixing block 8 slides downward according to the height of the container, and the lower side of the container is fixed by the second fixing block 8. Meanwhile, the anti-falling plate 10 is pushed to the lower side of the container by the air cylinder 15, and with the support of the support block 11, the situation of the container falling during hoisting is prevented.

[0034] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments.
