Stay cable single-time synchronous tensioning device and stay cable single-time synchronous tensioning method
The invention relates to a stay cable single-time synchronous tensioning device, and relates to the technical field of bridge construction, the tensioning device comprises more than two layers of tensioning assemblies, and each layer of tensioning assembly is used for tensioning a layer of stay cable; each layer of tensioning assembly comprises a PLC, a power device, a plurality of pairs of centerhole jacks and a plurality of pressure sensors, and each pair of center hole jacks are symmetrically arranged at the two ends of the anchor beam. The power device is used for controlling all the center hole jacks; the plurality of pressure sensors are mounted on the center hole jack one by one; the PLC is connected with all the pressure sensors and the power device, and the PLC controls the center hole jacks to synchronously tension the multiple layers of stay cables. The invention further discloses a tensioning method of the stay cable single-time synchronous tensioning device. The stay cable single-time synchronous tensioning device solves the technical problems that in the multi-cable-surface multi-layer stay cable tensioning process in the prior art, the number of process conversion times is large, the construction efficiency is low, cable force tensioning is unbalanced, and the tensioning precision is poor.
本申请涉及一种斜拉索单次同步张拉装置，涉及桥梁施工技术领域，张拉装置包含两层以上张拉组件，每层张拉组件用于张拉一层斜拉索；每层张拉组件包含PLC控制器、动力装置、多对穿心千斤顶以及多个压力传感器，每对穿心千斤顶对称布置于锚梁的两端；动力装置用于控制所有穿心千斤顶；多个压力传感器一一安装于穿心千斤顶；PLC控制器分别与所有压力传感器和动力装置连接，PLC控制器分别控制穿心千斤顶同步张拉多层斜拉索。本申请还公开了一种上述斜拉索单次同步张拉装置的张拉方法。本申请解决了现有技术多索面多层斜拉索张拉过程中，工序转换次数多、施工效率低、索力张拉不均衡以及张拉精度差的技术问题。
