Column pulling device for water conservancy project
The invention relates to the technical field of pile pulling machines, and discloses a column pulling device for hydraulic engineering, which comprises a base, a hydraulic cylinder group is arranged on the inner side surface of the base, a shaft rod is fixedly mounted on an output shaft of the hydraulic cylinder group, and an extrusion disc is eccentrically pin-connected to the top of the shaft rod; the outer surface of the extrusion disc is in pin joint with a first pressing plate with the inner wall making contact with the pile body. According to the column pulling device for the water conservancy project, due to the arrangement of the first pressing plate, when the shaft rod moves upwards for pile pulling operation, the first pressing plate can be forced to automatically clamp the outer surface of a pile body, and the second pressing plate is actively separated from the outer surface of the pile body; the first pressing plate can be forced to be actively separated from the outer surface of the pile body, the second pressing plate automatically clamps the outer surface of the pile body and supports the pile body, and the problem that the pile body slides down in the up-down reciprocating pile pulling process of the hydraulic pile pulling machine can be effectively solved due to inclined arrangement of the connecting rod while the pile body is prevented from toppling over.
本申请涉及拔桩机技术领域，且公开了一种水利工程用拔柱装置，包括底座，所述底座的内侧面设有液压缸组，所述液压缸组的输出轴上固定安装有轴杆，所述轴杆的顶部偏心销接有挤压盘，所述挤压盘的外表面销接有内壁与桩体相接触的第一压板。本申请提供的一种水利工程用拔柱装置，对于第一压板的设置，当轴杆向上移动进行拔桩作业时，可迫使第一压板自动卡紧桩体的外表面，而第二压板主动脱离桩体的外表面，而当轴杆向下发生移动时，可迫使第一压板主动脱离桩体的外表面，而第二压板自动卡紧桩体的外表面并对其进行支撑，在防止其发生倾倒的同时，因连杆的倾斜布置，可有效避免桩体在该液压拔桩机上下往复拔桩的过程中发生下滑的问题。
