100M Rail Synchronous Intelligent Group Crane
update time：2025/1/6 16:30:56
The base needs 6 fixed gantries to move the 100-meter-long rails as a whole to load and unload. If manual operation is adopted, the rails will be clamped and placed manually, and the rails will be positioned visually, which requires the coordinated work of 6 or more people. In addition, various deviations will occur due to human factors, and the rails are prone to twisting and deformation during the lifting process. Moreover, personnel need to constantly get on and off the flat car, which poses a safety hazard.
In response to the above problems, Zhuzhou Changyuan Intelligent Manufacturing Co., Ltd. has developed a new 100-meter-long Rail Synchronous Intelligent Group Crane Control System which is a new control system with synchronous action, accurate positioning, and automatic clamping and release functions. The entir e loading and unloading process only requires one driver to operate, which can realize all functions such as rail stacking storage position recording, automatic movement to the position after entering the address number, automatic clamping and releasing of the clamp, fault alarm and protection, etc.
The system uses Gray busbar positioning device, tension sensor to realize signal collection, field bus to control signal transmission, variable frequency speed regulation for trolley running, and PLC control system for host control system to realize automatic synchronous control system and simplify the work process. One person can operate multiple or all electric hoists to realize centralized lifting and handling operations of 100-meter-long rails,thereby improving work efficiency, saving production costs, and ensuring construction safety.
In this scheme, the long rail group crane synchronous intelligent mobile centralized control system adopts field bus control technology, and the central control station and field control station form a distributed control structure. The central control station is responsible for unified command of all 6 on-site control stations and can realize single control/group control functions of 6 cranes. The on-site control station is responsible for the execution of each crane. The central control station and the field control station are connected via a bus.
The synchronous detection of cranes in the system is realized by Gray bus positioning technology. The position signal detection of the crane moving in the horizontal direction is realized by installing Gray bus on each crane. The position of each crane can be transmitted to the centralized control station in real time through each field control station. The centralized control station makes unified dispatch and adjustments according to the position of each crane. At the same time, the horizontal movement direction transmission is controlled by a frequency converter. The centralized station dynamically adjusts the output frequency of each frequency converter according to the current position and destination address of each crane and the reference crane position to ensure the synchronization of the positions of each crane and accurately control the crane to stop at the destination address.
During the crane lifting process, the system uses a tension sensor to collect the weight of the crane and transmits the collected signal to the PLC substation system via RS232C communication. The centralized control console performs corresponding logical processing according to the weight information transmitted from each on-site control console to ensure that each crane carries the weight of the rails at the same time and keeps the load of each crane balanced. When a crane is overloaded or underloaded, the lifting height of the crane can be dynamically adjusted to ensure that all cranes are on the same height line, thereby ensuring that each crane has safely lifted the correct rails. At the same time, the weight information of each crane is sent to each main control station, so that the operator can observe the hook status of each crane in real time and dynamically, avoiding major accidents such as wrong hooking or unhooking during the lifting process, and ensuring smooth and safe lifting.
