Description

A container twist lock automatic unlocking device

technical field

The utility model relates to port machinery, in particular to an automatic unlocking device for container twist locks.

Background technique

The removal of the container twist lock 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 unlock and remove the lock to put it into the twist lock collection box, which obviously affects the loading and unloading efficiency. Efficient loading and unloading is the key to the rapid collection and distribution of goods in ports. 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 and twist lock on the ground, and a large ship with a length of more than 200m needs at least 6 to 10 people who specialize in disassembling and disassembling container twist locks. 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. According to the statistics and analysis of accidents in Japan, the casualty rate of industrial accidents in Japanese port loading and unloading operations is second only to mining and forestry departments. In recent years, industrial accidents have occurred frequently in my country's coastal ports.

In order to change the above-mentioned deficiencies, the utility model proposes a container twist lock automatic unlocking device, which mainly realizes the automatic removal of the container twist lock by identifying and locating the twist lock model of the container through the unlocking actuator.
