Electrical control system for hydraulic-type container crane

Abstract

The invention discloses an electrical control system for a hydraulic-type container crane. A PLC is adopted as a main controller, and under control of the PLC, control over all executing components isachieved through a relay. The electrical control system is good in working stability and high in reliability, and meets the expected design requirement. In addition, the hydraulic-type container crane adopts semi-automatic control, thus the time used by the hydraulic-type container crane for completion of one-time mounting and dismounting is shorter, and the working efficiency is higher.

Description

technical field [0001] The invention relates to an electrical control system of a hydraulic container crane, which is suitable for the mechanical field. Background technique [0002] Container cranes are an important type of cranes, mainly used for hoisting, stacking and handling of containers in industrial production industries such as ports, cargo yards, coal yards, mines, and metallurgy. At present, most of the container cranes suitable for large freight yards and ports are rail-mounted and wire rope hoisting, and their structure types are gradually becoming standardized and serialized. However, in some small and medium-sized freight yards or In mines, container cranes are very irregular, and most of them are transformed from traditional door and bridge cranes. Due to the actual loading site, it is often necessary for the container to tilt at a certain angle during the loading process. After the cargo is full, it is lifted by the crane. Loading, in this way, in the proce...

At present, most of the container cranes suitable for large freight yards and ports are rail-mounted and wire rope hoisting, and their structure types are gradually becoming standardized and serialized. However, in some small and medium-sized freight yards or In mines, container cranes are very irregular, and most of them are transformed from traditional door and bridge cranes. Due to the actual loading site, it is often necessary for the container to tilt at a certain angle during the loading process. After the cargo is full, it is lifted by the crane. Loading, in this way, in the process of cargo lifting, the tilt of the container often causes the cable pull and overload of the crane, and the wire rope is broken or the hoisting motor is burned.
