Sectional type hollow grouting anchor cable end anchoring device
The invention relates to the technical field of anchor cable end anchoring, in particular to a sectional type hollow grouting anchor cable end anchoring device which comprises a crawler-type chassis, a rotating unit, a drilling unit, a lifting unit and a steel wire tensioning unit. According to an existing sectional type hollow grouting anchor cable end fixing mode, expected anchoring force can not be achieved in special geology, and the supporting system failure phenomena such as slippage and instability are likely to occur. The rotating unit, the drilling unit, the lifting unit and the steel wire tensioning unit adopted by the detection device for the wheel set of the running gear of the railway vehicle are matched, the supporting plate can be driven to move to the needed position, the problem that the position of the crawler-type chassis deviates during working is avoided, drilling can be conducted on the end face of a foundation pit, a ground pile is installed, and the detection efficiency is improved. The effect of locking and fixing the centers of the multiple hollow grouting anchor cables is achieved by controlling the tightening force of the steel wire ropes, the problem that the supporting system fails due to slippage instability is solved, the multiple hollow bolts are installed or detached at the same time, and the working efficiency is improved.
本发明涉及锚索端头锚固技术领域，特别涉及一种分段式中空注浆锚索端头锚固装置，包括履带式底盘、旋转单元、钻孔单元、抬升单元、钢丝拉紧单元。现有的分段式中空注浆锚索端头固定方式在特殊地质可能无法实现预期的锚固力，易出现滑移失稳等支护系统失效现象。而本发明提供的一种用于轨道车辆走行部轮对检测装置所采用的旋转单元、钻孔单元、抬升单元、钢丝拉紧单元配合，可以带动支撑板移动至所需的位置，且避免工作时履带式底盘位置偏移的问题，可以对基坑端面进行钻孔安装地桩，通过控制钢丝绳的绷紧力度实现多个中空注浆锚索中心处锁紧固定的效果，避免出现滑移失稳等支护系统失效现象的问题，且同时安装或拆卸多个中空螺栓，提高工作效率。
