Method and system for intelligently and synchronously tensioning and fastening cable clamp screw
The invention discloses a method and a system for intelligently and synchronously tensioning and fastening a cable clamp screw, and relates to the technical field of bridge construction. The method comprises the following steps that tensioning devices are installed on all screws to be fastened, and all the tensioning devices are connected with the same industrial PC; the industrial PC is used for controlling all the tensioning devices to synchronously carry out tensioning and fastening operation, and the tensioning and fastening operation comprises the steps of synchronously tensioning a screw rod and fastening a nut; after the tensioning and fastening operation is finished, based on the sound time data, the temperature data and the screw physical data, the screw axial force Ft after fastening is completed is obtained; the Ft is compared with the designed construction axial force Fd of the screw; and if all Ft is larger than or equal to Fd of the first preset multiple, the screw tensioning and fastening construction is completed. According to the method, the obtained axial force Ft of the screw and the designed construction axial force Fd of the screw are compared to judge the tensioning and fastening construction condition of the screw, so that the tensioning and fastening quality of the screw is judged.
本发明公开了一种索夹螺杆智能同步张拉紧固的方法和系统，涉及桥梁建设技术领域。该方法包括以下步骤：在所有待紧固的螺杆上安装张拉器，并使各个张拉器与同一个工业PC连接；利用工业PC，控制所有的张拉器同步地进行张拉紧固操作，所述张拉紧固操作包括同步地对螺杆进行张拉和对螺母进行紧固；待张拉紧固操作结束后，基于声时数据、温度数据和螺杆物理数据，获得紧固完成后的螺杆轴力Ft；将Ft与螺杆的设计施工轴力Fd进行对比；若所有Ft大于等于第一预设倍数的Fd，则螺杆张拉紧固施工完成。本发明可通过获得的螺杆轴力Ft和螺杆的设计施工轴力Fd进行对比，来判断螺杆张拉紧固施工的情况，以此来判断螺杆的张拉紧固质量。
