Description

Technical Field

[0001] The present invention relates to the technical field of container disassembly and assembly locks, and in particular to a bridge crane auxiliary trolley and a use method thereof. Background Art

[0002] The locks of containers are mainly used to fix and connect adjacent containers to ensure that the containers will not shift or tip over during transportation. Unlocking containers is an important part of the container transportation process, which involves the safe fixing and release of containers. At present, the commonly used container locks are automatic locks, which are portable container lashing equipment. The working principle is to automatically turn and lock under the action of the gravity of the container. When the container is lifted off the ship, when the gravity of the container is completely borne by the dock crane, the torque of the crane causes the internal device of the twist lock to turn and reset to the open state, and then it is lifted up again, without the need to manually unlock the lock. After the container is unloaded from the ship by the bridge crane or when it is shipped from land to the ship, it is necessary to perform locking operations on the container.

[0003] For this purpose, an automated container terminal unlocking system has emerged, such as the one disclosed in the patent publication number CN114368627A, which includes a shore container loading and unloading bridge, an AGV automatic guided vehicle and an unlocking isolation island. An operating table for unlocking operations is provided on the unlocking isolation island. The unlocking operations are completed manually or by a robot on the unlocking isolation island, and the interaction is completed with the AGV automatic guided vehicle through an intelligent electronic control system. The unlocking isolation island is fixed or movable.

[0004] The above solution has the following problems: 1. The distance adjustment between the two oppositely arranged padlock release isolation islands is relatively complicated. It is necessary to control the walking mechanism of the padlock release isolation islands to adjust repeatedly to achieve a suitable distance between the two to meet the needs of loading and unloading operations of containers of different specifications, which affects work efficiency.

[0005] 2. When unlocking the padlock, there is a situation where the unlocking of the four corners of the bottom of the container is not completed before the subsequent operation, which brings great safety hazards to the personnel. To solve this problem, the above solution uses industrial robots instead, but the cost is high, which affects the promotion and use. Summary of the invention

[0006] In view of the problem that the distance adjustment between two oppositely arranged unlocking isolation islands is relatively complicated and affects work efficiency, the present invention provides a bridge crane auxiliary trolley.
