Cable-stayed bridge inhaul cable tensioning device and using method thereof
The invention discloses a cable-stayed bridge inhaul cable tensioning device and a using method thereof, and belongs to the technical field of inhaul cable tensioning, the cable-stayed bridge inhaul cable tensioning device comprises an outer cylinder, an inner cylinder, a pushing mechanism and a tensioning mechanism, the outer cylinder is fixedly connected to the inner cylinder in a sleeving mode, the tensioning mechanism and the pushing mechanism are both arranged on the outer cylinder, the tensioning mechanism is located between the outer cylinder and the inner cylinder, and the tensioning mechanism is connected with the pushing mechanism; by arranging the inner cylinder and the outer cylinder, after the inner cylinder and the inhaul cable are fixedly connected, hydraulic oil is injected into the oil return nozzle, the inner cylinder and the outer cylinder can move on the movable cylinder and the sliding rod, the outer cylinder and the inner cylinder are moved in a reciprocating mode, the inhaul cable can be tensioned, the inner cylinder and the outer cylinder are fixed to the inhaul cable and cannot move, and hydraulic oil is injected into the oil inlet nozzle; the moving cylinder extends out to drive the jacking cylinder to make contact with the bridge body, so that the jacking cylinder can move in place, the moving cylinder is prevented from moving towards one side of the bridge body during tensioning, then the tensioning stroke is prevented from being affected, and the tensioning efficiency is improved.
本发明公开了一种斜拉桥拉索张拉装置及其使用方法，属于拉索张拉技术领域，包括外筒、内筒、推送机构和张拉机构，外筒固定套接在内筒上，张拉机构和推送机构均设置在外筒上，张拉机构位于外筒和内筒之间，张拉机构与推送机构相连接；通过设置内筒和外筒，将内筒与拉索固定连接后，向回油嘴内注入液压油，内筒和外筒能够在移动筒和滑杆上移动，往复移动外筒和内筒，能够对拉索进行张拉，将内筒和外筒固定在拉索上无法移动，向进油嘴注入液压油，移动筒伸出带动顶压筒与桥体接触，使得顶压筒能够移动到位，避免张拉时移动筒向桥体一侧移动，进而避免对张拉行程造成影响，提高张拉时的效率。
