Pile pulling machine and pile pulling method
The pile pulling machine comprises hoisting equipment and a pile pulling accessory pivoted to a mechanical arm, and the pile pulling accessory is provided with an accessory shell, a sliding frame sliding up and down in the accessory shell, two clamping blocks rotationally pivoted to the lower end of the sliding frame and a hydraulic oil cylinder; one end of the hydraulic oil cylinder is pivoted on the sliding frame, and the other end is pivoted on the accessory shell; the hydraulic oil cylinder is driven to push the sliding frame to move upwards to drive the two clamping blocks to rotate to clamp the pile and pull the pile up; according to the pile pulling machine, the hydraulic oil cylinder is used for clamping and pulling a pile, in the pile pulling process, acting force for clamping the pile is provided for the clamping block all the time, the pile clamping structure is more stable, loosening or slipping of the clamping block and the pile clamping structure of the pile in the pile pulling process can be avoided, the pile pulling clamping force is high, the pile can be pulled out more easily and rapidly, and the pile pulling efficiency is improved. The pile pulling effect and the pile pulling efficiency are high; and in addition, the using number of hydraulic oil cylinders is reduced, the equipment cost of the pile extractor is reduced, and the pile extracting method is simpler and safer.
本发明公开了一种拔桩机及拔桩方法，包括吊装设备和枢接于机械臂上的拔桩属具，拔桩属具具有属具外壳、于属具外壳内上下滑动的滑动架、转动枢接于滑动架下端的两夹持块和液压油缸；液压油缸一端枢接于滑动架上，另一端枢接于属具外壳上；驱动液压油缸推动滑动架向上运动带动两夹持块转动夹紧桩并拔起桩；本发明拔桩机利用一个液压油缸进行夹桩和拔桩工作，在拔桩过程中，一直给夹持块提供夹紧桩的作用力，夹桩结构更稳固，可以避免拔桩过程中夹持块和桩的夹桩结构松动或滑脱，拔桩夹紧力强，使桩更容易快速拔出，拔桩效果和拔桩效率高；而且节省液压油缸的使用数量，降低拔桩机的设备成本，且拔桩方法更简单、安全。
