Vertical rotating device for V-shaped main tower of extradosed hybrid beam cable-stayed bridge and construction method
The invention discloses an extradosed hybrid beam cable-stayed bridge V-shaped main tower vertical rotating device and a construction method, and belongs to the field of bridge construction equipment, the extradosed hybrid beam cable-stayed bridge V-shaped main tower vertical rotating device comprises a base, traction devices are symmetrically and fixedly connected to the upper end of the base, and a plurality of protection devices are further installed at the upper end of the base. According to the invention, firstly, the side tower column is aligned with the lower tower column, then the hydraulic rod and the hydraulic ejector rod are started, the hydraulic ejector rod can upwards jack the side tower column to enable the side tower column to rotate upwards, the hydraulic rod can stretch and contract back and forth after being started, and the traction steel rope can be pulled under the mutual cooperation of the dragging block and the locking sleeve in the stretching and contracting process of the hydraulic rod; by means of the mode, the traction steel cable can be pulled all the time, so that the traction steel cable is used for pulling the side tower column to enable the side tower column to be aligned with the lower tower column, the installation time of the whole supporting tower column of the cable-stayed bridge can be greatly saved, meanwhile, large hoisting equipment is prevented from being used for assisting installation, and cost is greatly saved.
本发明公开了一种矮塔混合梁斜拉桥V型主塔竖转装置及施工方法，属于桥梁建设设备领域，包括底座，所述底座的上端对称固定连接有牵引装置，所述底座的上端还安装有若干防护装置。本发明，先将侧塔柱与下塔柱对齐，然后开启液压杆和液压顶杆，液压顶杆会向上顶起侧塔柱使其向上转动，液压杆开启后会来回伸展和收缩，液压杆伸展和收缩的过程中在拖动块和锁紧套的相互配合下即可对牵引钢索进行拉拽，通过此种方式便可一直对牵引钢索进行拉拽，从而利用牵引钢索对侧塔柱进行拉拽使其与下塔柱对齐，通过此种方式可大大节约斜拉桥整个支撑塔柱的安装时间，同时也避免了使用大型吊装设备来辅助安装，进而大大节约了成本。
