Remote control system for gantry crane

Abstract

The invention relates to a remote control system for a gantry crane. The remote control system comprises a cloud server platform, a client, a remote control operation table, a fixed base station, a gantry machine monitoring terminal, a grab bucket monitoring part and a bow and stern positioning device. The cloud server platform is connected with the client and the remote control operation table through a fifth switch. The cloud server platform is connected with the portal machine monitoring terminal through a 5G communication module, and the portal machine monitoring terminal is connected with the grab bucket monitoring part. The portal machine monitoring terminal, the grab bucket monitoring part and the bow and stern positioning device are all in communication connection with the fixed base station. According to the remote control system for the gantry crane, remote control of the gantry crane is achieved, communication networking with a production dispatching system can be achieved, and the technical support is provided for unmanned operation of a wharf, cost reduction and efficiency improvement.

Description

technical field [0001] The invention relates to the technical field of portal crane control, in particular to a portal crane remote control system. Background technique [0002] The portal crane is also called a jib type crane in which the rotatable lifting device (referred to as the rotating part) is mounted on the portal frame. The 4 legs of the gantry form 4 "door openings" through which railcars and other vehicles can pass. Most of the portal cranes run along the crane track on the ground or on the building for lifting and unloading operations. At present, portal cranes are mainly used for port machinery operations. The bridge frame is supported on the ground track or foundation through the outriggers on both sides, and has the characteristics of running along the ground track and passing railway vehicles or other ground vehicles below. Portal cranes have also been gradually extended to berths and hydroelectric power station sites where the operating conditions are si...

AI Technical Summary

Problems solved by technology

However, due to the special working conditions of portal cranes, there is no relatively advanced control system in the prior art to meet the increasingly precise needs of current portal cranes.

[0003] The document "Application of PLC Remote Monitoring System on Portal Cranes" (Automation Control, Rao Laiqing) records the remote monitoring scheme of portal cranes, which has certain disadvantages, which are manifested in: ①. Monitoring the equipment failure of the portal machine does not mention the improvement of productivity and the reduction of labor intensity of operators

②. This solution is transmitted through GPRS, the data channel is relatively small, and the amount of data transmitted wirelessly is small, which objectively limits its remote transmission function

③. This solution does not have GPS positioning function, image recognition function, and grab anti-swing function
