Pile extractor for water conservancy project and using method of pile extractor

LI ZHIQIANG

The invention discloses a pile pulling machine for hydraulic engineering and a using method thereof.The pile pulling machine for the hydraulic engineering comprises a moving box, a stress block is arranged on the front side of the moving box in a sliding mode, a machine head is fixedly arranged at the front end of the stress block, a clamping and fixing mechanism is connected to the front side of the machine head through a clamping drive, and a vibrating assembly is arranged on the inner side of the clamping and fixing mechanism; the clamping and fixing mechanism loosens the pile body through the vibration assembly. According to the device, before the pile body is pulled out, the pile body can be vibrated and loosened up and down through the vibration assembly, the influence of piston force is avoided, the burden of the device can be reduced, and the pulling-out efficiency can also be improved.

本申请公开了一种水利工程用拔桩机及其使用方法，该水利工程用拔桩机包括移动箱，移动箱的前侧滑动设置有受力块，受力块的前端固定设置有机头，机头的前侧通过夹紧驱动连接有夹持固定机构，夹持固定机构的内侧设置有颤动组件，夹持固定机构通过颤动组件对桩体进行松动。本申请中，在拔出桩体之前，可以通过颤动组件对桩体进行上下震颤松动，避免了活塞力的影响，不仅可以减少设备本身的负担，而且也可以提高拔出的效率。
