Integral strand pulling device and method for long-distance steel strands
The invention provides an integral strand pulling device and method for the long-distance steel strands, winches are arranged at the two ends correspondingly, a steel wire rope of the winch at the penetrating-out end is brought to the penetrating-in end through a strand pulling machine and a first steel strand, and then the steel wire rope conveyed into the winches is brought to the penetrating-out end and connected with the whole strand of steel strands; therefore, the whole bundle of steel strands can be penetrated through the winch at the penetrating-in end, the central steel wires of the multiple strands of steel strands do not need to penetrate into an upset head and then are connected with a traction head and a traction sleeve, the problems that single strand penetration consumes time and is prone to winding and uneven stress are solved, and meanwhile the problems that in existing whole strand penetration, the cutting and strand penetration workload is large, the working efficiency is low and the steel strands are wasted are solved, the requirement for large equipment is reduced, and the equipment and transportation cost is further reduced. The invention belongs to the technical field of bridge construction.
本发明提供一种长距离钢绞线整体穿束装置及方法，通过两端分别设置卷扬机，利用穿束机及首根钢绞线将穿出端卷扬机的钢丝绳带到穿入端，再将传入到卷扬机的钢丝绳带到穿出端并连接整束钢绞线，从而利用穿入端的卷扬机即可将整束钢绞线穿束，无需将多股钢绞线的中心钢丝穿入镦头，然后连接牵引头和牵引套，解决了单根穿束耗费时间且容易发生缠绕和受力不均的问题，同时，解决了现有整体穿束的切割和穿束工作量大，工作效率低，且会造成钢绞线浪费的问题，降低了对大型设备的需求，进一步降低设备及运输成本。属于桥梁施工技术领域。
