Automatic loading and unloading system for bridge crane

Abstract

The invention discloses an automatic loading and unloading system for a bridge crane, and relates to the field of bridge crane loading and unloading. The system comprises a frame body, a lifting appliance, a master control module and a positioning device. The frame body comprises a pair of vertical frames parallel to the ground, a pair of transverse frames sliding in the direction of the vertical frames and a movable frame sliding in the direction of the transverse frames, a lifting appliance is arranged on the movable frame, and a laser scanning range finder is arranged at the position of a groove above a lifting hook of the lifting appliance. First motors for providing movement power for the transverse frames are arranged on the transverse frames, a second motor for providing movement power for the movable frame is arranged on the movable frame, and a third motor for controlling the lifting appliance to ascend and descend is arranged on the lifting appliance. The positioning device is arranged on the ground at the bottom of the frame body, the positioning device comprises a first induction layer, a circuit distribution layer and a second induction layer which are arranged from top to bottom, the first induction layer is provided with a plurality of protruding pieces which can be pressed down by gravity, the bottom of each protruding piece is provided with a conductive element, and the circuit distribution layer passes through the lower portion of each protruding piece to connect the protruding pieces in series and in parallel.

Description

technical field [0001] The invention relates to the field of loading and unloading of bridge cranes, in particular to an automatic loading and unloading system of bridge cranes. Background technique [0002] The bridge crane is a crane used for loading and unloading operations on the terminal. It is the heart of the terminal. The operating capacity of the bridge crane determines the cargo handling capacity of a terminal. At present, it is generally still to manually operate the crane to load and unload the goods, which has great requirements on the master's operating skills, and the manual labor is prone to fatigue. The goods that can be loaded and unloaded in a day are limited, and the economic cost is high. The general automatic loading and unloading device , the sensor combination of various types of induction identification is mostly used, and the requirements for the sensor are high, and due to the large moving area of ​​the hoisted goods, multiple sensors are required,...

At present, it is generally still to manually operate the crane to load and unload the goods, which has great requirements on the master's operating skills, and the manual labor is prone to fatigue. The goods that can be loaded and unloaded in a day are limited, and the economic cost is high. The general automatic loading and unloading device , the sensor combination of various types of induction identification is mostly used, and the requirements for the sensor are high, and due to the large moving area of ​​the hoisted goods, multiple sensors are required, and good sensors are relatively expensive.
