Abstract

The invention discloses a railway gantry crane lifting appliance positioning control system and method. According to the railway gantry crane lifting appliance positioning control system and method, a laser scanner is mounted on a crane trolley and scans containers, trains and container trucks which are transversely and vertically stacked below a lifting appliance; vehicle and container stacking conditions of a storage yard below the position where a crane is located and an adjacent storage yard are obtained in real time, and the position of a trolley, the lifting height of the lifting appliance, and distribution positions and stacking heights of the containers on the storage yard and trains and heavy-load container trucks under a gantry crane are measured. According to data measured by a laser scanner technology, the data is calculated by a controller and sent to a PLC, the lifting process is controlled to prevent the lifting appliance or a lifted container from colliding with the container on the storage yard in the lifting process, and the functions of lifting collision prevention, train position positioning, stacked container positioning, container truck positioning, automatic soft container landing and the like are achieved; when the container is lifted, a laser sensor on the lifting appliance is used for accurately measuring a train plate, so that the train plate is prevented from being lifted when a lock head is not unlocked in the lifting process.

Description

technical field [0001] The invention relates to the hoisting control of a gantry crane used in container loading and unloading operations, and is especially suitable for the automatic crane loading and unloading operations of gantry cranes in railway train freight yards. Background technique [0002] At present, there is no effective and accurate measurement method for container gantry crane lifting control in railway and train freight yards. Railway train freight yard complex, gantry cranes spanning train tracks, container box areas and container truck lanes. During hoisting, the alignment between the container on the train or the container truck and the crane spreader depends on the driver's manual visual inspection. When the spreader descends close to the container, the driver moves the spreader repeatedly according to the position of the spreader and the container according to the visual inspection. This method seriously reduces the loading and unloading capacity. Speed...
