Intelligent control inhaul cable prestress adjusting device and cable force adjusting and controlling method thereof
The invention discloses an intelligent control inhaul cable prestress adjusting device and a cable force adjusting and controlling method thereof. The intelligent control inhaul cable prestress adjusting device is mounted at the end part of a structure with an inhaul cable; the intelligent control inhaul cable prestress adjusting device comprises an external bolt rod, a hydraulic cylinder, a piston block, a servo oil pump, an adjustable bolt, a straight-through pressure sensor, a servo motor, a screwing gear and an intelligent control system. The intelligent control inhaul cable prestress adjusting device is mounted and connected to the end part of the inhaul cable of an existing large-span building structure; through the intelligent control system, the hydraulic cylinder is controlled toeject the external bolt rod at the end part of the inhaul cable; through the servo motor, the adjustable bolt is driven to be screwed in or out; and therefore, intelligent adjustment of cable force isachieved; the hydraulic cylinder applies oil pressure only when the cable force is adjusted, no oil pressure exists at ordinary times, and therefore, oil leakage can be effectively avoided; and the adjustable bolts are screwed in and screwed out under the condition that the adjustable bolts are not stressed, so that the torque needing to be rotated by the servo motor is smaller, the overall structure is simple and reliable, application and popularization are easy, and the adjusting effect is good.
本发明公开了一种智能控制拉索预应力调整装置及其索力调控方法，调整装置安装在具有拉索的结构端部；包括外接螺栓杆、液压缸、活塞块、伺服油泵、可调螺栓、穿心式压力传感器、伺服电机、拧动齿轮和智能控制系统；本发明提供的智能控制拉索预应力调整装置在现有的大跨度建筑结构的拉索端部安装连接，通过智能控制系统控制液压缸顶动拉索端部的外接螺栓杆，通过伺服电机驱动拧进或拧出可调螺栓，实现对索力的智能调整，液压缸只有在索力调整时才施加油压，平时无油压，能够有效避免漏油；拧进拧出可调螺栓均是在可调螺栓不受力情况下进行，需要伺服电机转动的力矩较小，整体结构简单可靠，易于推广使用，调节效果好。
