Port crane lifting system and stacking method thereof

Abstract

The invention relates to the field of port machinery, and discloses a port crane lifting system and a stacking method thereof. The port crane lifting system comprises a hanger, N lifting ropes used for lifting the hanger and L distance measuring sensors. The L distance measuring sensors which are perpendicularly downwards mounted at the bottom periphery of the hanger are used for sending real-time detected distance values to a controller of a port crane; the controller is used for judging whether the distance values detected by the L distance measuring sensor generate jumping or not; when the detected distance values generate jumping, identifying the edge position of a lower container by the controller according to the distance values detected by the L distance measuring sensors; and carrying out stacking calibration by the controller according to the identified edge position. According to the implementation mode of the invention, high-precision stacking can be realized without labor power, the safety coefficient of port stacking further can be improved, and accidents and economic loss are reduced.

Description

technical field [0001] The invention relates to the field of port machinery, in particular to a port crane lifting system and a stacking method thereof. Background technique [0002] With the development of economy and the increase of port throughput, the efficiency and safety of crane stacking have been paid more and more attention by people. [0003] At present, the stacking of cranes requires the driver to stay in the driver's cabin, aim at the container stacking site from a high altitude, and then operate manually. This method requires high vision and experience of the driver. If the driver is unskilled in operation or has poor eyesight or fatigue driving for a long time, he will not be able to stack with high accuracy continuously and for a long time. Moreover, once a mistake occurs, it is very likely that the container will be unstable and roll down, not only causing unnecessary economic losses, but also likely to injure the on-site personnel. In addition, the origin...

Problems solved by technology

If the driver is unskilled in operation or has poor eyesight or fatigue driving for a long time, he will not be able to stack with high accuracy continuously and for a long time

Moreover, once a mistake occurs, it is very likely that the container will be unstable and roll down, which will not only cause unnecessary economic losses, but may also seriously injure the personnel on site.

In addition, the original manual operation requires one person for each machine, which is inefficient and wastes resources
