Main cable pre-tightening machine and using method thereof
The invention belongs to the technical field of suspension bridge main cable construction, and particularly relates to a main cable pre-tightening machine and a using method thereof. A main cable pre-tightening machine comprises a fastening machine frame, a walking system is arranged on the top of the fastening machine frame, an impact system and a fastening system are arranged in the fastening machine frame, the fastening system comprises two fastening air cylinders and two shifting fork levers, and two fastening steel wire ropes are connected between the two shifting fork levers. The two fastening air cylinders are fixed to the outer side faces of the two sides of the fastening rack respectively, the impact system comprises two impact type pneumatic hammers, a vibration plate and a plurality of spring buffers, the spring buffers are fixedly installed on the top of the inner side of the fastening rack, the vibration plate is connected to the lower ends of the spring buffers, and the impact type pneumatic hammers are fixedly connected to the inclined upper portions of the two sides of the vibration plate respectively. The fastening force of the fastening steel wire rope on the main cable is adjusted through the fastening air cylinder, the impact type pneumatic hammer is adopted to replace manual work to beat the main cable, the main cable pre-tightening speed and quality are improved, and the construction cost is reduced.
本发明属于悬索桥主缆施工技术领域，特别涉及一种主缆预紧缆机及其使用方法。一种主缆预紧缆机，包括紧固机架，紧固机架顶部设有行走系统，紧固机架内部设有冲击系统和紧固系统，紧固系统包括两个紧固气缸和两个拔叉杠杆，两个拔叉杠杆之间连接有两条紧固钢丝绳，两个紧固气缸分别固定在紧固机架两侧的外侧面，冲击系统包括两个冲击式气动锤、振动板和多个弹簧缓冲器，弹簧缓冲器固定安装在紧固机架内侧顶部，弹簧缓冲器下端连接有振动板，振动板两侧斜上方分别固定连接有冲击式气动锤。本发明通过紧固气缸调节紧固钢丝绳对主缆的紧固力，并采用冲击式气动锤代替人工敲打主缆，提高了主缆预紧速度及质量，降低施工成本。
