Arch bridge double-suspender synchronous tensioning device and synchronous tensioning method and system
The invention discloses an arch bridge double-suspender synchronous tensioning device, a synchronous tensioning method and a synchronous tensioning system. The device comprises a supporting system, a loading system and a tensioning system, the loading system is arranged on a supporting platform in the supporting system and comprises a loading lever, a support rod and a loading device, and the tensioning system comprises a main tensioning rod, a hydraulic rod and a hoop; the rear end of the loading lever is rotatably connected with the upper end of the support rod, the support rod is fixed on the supporting platform, the front end of the loading lever is movably connected with the upper end of the main tension rod, the lower end of the main tension rod is provided with a pair of hydraulic rods with different telescopic directions, and the rod ends of the hydraulic rods are respectively provided with a hoop; the loading device is arranged on the supporting platform, located below the loading lever and used for applying loads to the loading lever. The two suspenders are further provided with stress sensors for actually measuring tensioning force of the suspenders, the telescopic length of the hydraulic rods is adjusted according to the tensioning force difference value, and symmetrical and synchronous tensioning is guaranteed. The tensioning force control precision is high, construction is safe and convenient, environment friendliness is achieved, and the high engineering value is achieved.
本发明公开一种拱桥双吊杆同步张拉装置及同步张拉方法与系统。该装置包括支撑系统、荷载系统和张拉系统，荷载系统设于支撑系统中的支撑平台上，包括加荷杠杆、支座杆、加荷装置，张拉系统包括主张拉杆、液压杆、套箍；加荷杠杆后端与支座杆上端转动连接，支座杆固定于支撑平台上，加荷杠杆前端与主张拉杆上端活动连接，主张拉杆下端设有一对伸缩方向不同的液压杆，液压杆缸杆端各设有一套箍；加荷装置设于支撑平台上，位于加荷杠杆下方，向加荷杠杆施加荷载。两根吊杆还设有应力传感器实测吊杆张拉力，根据张拉力差值调节液压杆的伸缩长度，保证对称同步张拉。本发明张拉力控制精度高，施工安全便捷、绿色环保，具有较高的工程价值。
