Vibration type cable tightening machine for construction of main cable of suspension bridge and compaction method
The invention provides a vibration type cable tightening machine for suspension bridge main cable construction and a compaction method.The cable tightening machine comprises a fastening device, a moving device, a hydraulic system and a vibration device, the fastening device is arranged on a main cable in a sleeving mode, and the hydraulic system is connected with the fastening device and used for driving the fastening device to compress the main cable; the moving device is installed at the top of the fastening device and used for driving the fastening device to move along the main cable, and the vibration device is used for generating pressure waves under the action of vibration force and transmitting the pressure waves into a pressed steel wire. On the basis of pressing of the fastening device, vibration force is provided through the vibration device, a series of pressure waves generated by the vibration force can be transmitted into pressed steel wires, internal friction force between the pressed steel wires is reduced, the steel wires are made to move, repositioning of the steel wires is facilitated, and the steel wires are prevented from being damaged. And air among the steel wires is easier to reduce under the action of vibration force, so that the purpose of compaction is achieved, and the porosity of the main cable is greatly reduced.
本发明提供了一种悬索桥主缆施工振动式紧缆机及压实方法，紧缆机包括紧固装置、移动装置、液压系统和振动装置，所述紧固装置套设在主缆上，所述液压系统与紧固装置连接，用于带动紧固装置压紧主缆，所述移动装置安装在紧固装置顶部，用于带动紧固装置沿主缆运动，所述振动装置用于在振动力的作用下，产生压力波传递到被压钢丝中。本发明在紧固装置压紧的基础上，通过振动装置提供振动力，将振动力产生的一系列压力波会传递到被压钢丝中，降低被压钢丝与钢丝间的内摩擦力，使钢丝产生移动，不仅利于钢丝的重新定位，而且在振动力的作用下更容易减少钢丝之间的空气，达到压实的目的，大大减小主缆孔隙率。
