Description

A device for removing locks by twisting locks in the middle of a container

technical field

The utility model relates to port machinery, in particular to a device capable of realizing twisting and removing locks in the middle of containers.

Background technique

The middle twist lock of the container is mainly used for the connection and fixation of the container on the upper deck of the container ship and the upper and lower sides of the container. The removal of the twist lock in the middle of the container is an important link in the container loading and unloading process. At present, there are many container locking and unlocking process methods in container terminals in the world, but they all adopt manual installation and disassembly.

After the container ship arrives at the wharf, the twist lock is unlocked manually on the ship with a special pull rod. At this time, the twist lock is separated from the container below, but is still fixed on the corner fitting of the container above. Then the quay crane lifts the containers one by one and puts them on the container truck at the front of the wharf. Manually unlock the twist locks on the corner fittings under the containers one by one and put them into the collection box. shipped away. A container generally requires two workers to remove the lock at the same time. It takes at least tens of seconds to manually remove the lock, remove the lock and put it into the collection box, which obviously affects the loading and unloading efficiency.

We should give full play to the efficiency of loading and unloading machinery automation, try our best to achieve fast loading and unloading, direct loading and unloading, and simplify tedious manual loading and unloading steps. Shortening the loading and unloading time can shorten the time of vehicles, ships and goods in the port, and also shorten the entire logistics time, thereby improving logistics efficiency. If the loading and unloading activities are carried out slowly, the logistics speed will be greatly reduced, and the time of goods in the port will be prolonged, which will also have a series of corresponding impacts.

Manually dismantling twistlocks requires a lot of manpower and increases loading and unloading operating costs. On average, a container quay crane needs at least 2 workers to disassemble the twist lock on the ground, and a large ship with a length of more than 200 meters needs at least 6 to 10 people who specialize in disassembling and disassembling the twist lock in the middle of the container. The entire wharf production shoreline will take up a lot of labor to engage in this repetitive simple and boring work.

The work of workers dismantling and carrying the twist lock on site is not only labor-intensive, but also has potential safety hazards that cannot be ignored in the working environment. Port container handling equipment has the characteristics of large structure, complex mechanism, and variable load. In addition, the dock site is busy, and the flow of mobile machinery such as trucks is large. Danger.
