Prestress automatic tensioning system
The invention relates to the technical field of bridge construction, and particularly discloses an automatic prestress tensioning system which comprises a vehicle body. The bottom surface of the vehicle body is fixedly connected with a sleeve; a push block is slidably connected to the inner side wall of the sleeve. The bottom end of the push block extends to the bottom of the sleeve and is fixedly connected with a pressing plate located at the bottom of the sleeve. A first hydraulic push rod is arranged on the vehicle body; the output end of the first hydraulic push rod penetrates through the vehicle body, extends into the sleeve and is fixedly connected with the top surface of the push block; a tensioning mechanism capable of automatically tensioning a steel strand of a bridge is arranged on the vehicle body; when the tensioning mechanism conducts tensioning operation, the first hydraulic push rod drives the push block to move downwards, the pressing plate is promoted to move downwards and be pressed on the ground, the vehicle body is fixed, and the possibility that the vehicle body slides in the tensioning process is reduced.
本发明涉及桥梁施工技术领域，具体公开了预应力自动张拉系统，包括车体；车体底面固接有套管；套管内侧壁上滑动连接有推块；推块底端伸至套管底部，推块底端固接有位于套管底部的压板；车体上设置有第一液压推杆；第一液压推杆输出端贯穿车体伸至套管内与推块顶面固接；所车体上设置有可对桥梁的钢绞线进行自动张拉的张拉机构；在张拉机构进行张拉作业时，通过第一液压推杆带动推块下移，促使压板下移并压紧在地面上，对车体进行固定，降低车体在张拉过程中发生滑动的可能性。
