Bridge pile extractor suitable for multi-size pile heads and using method of bridge pile extractor
The invention discloses a bridge pile pulling machine suitable for pile heads of multiple sizes and a using method thereof, and relates to the technical field of bridge pile pulling, the bridge pile pulling machine comprises a cable contraction mechanism, and the lower end of the cable contraction mechanism is sleeved with a pile clamping mechanism. A driving motor works, through a series of transmission, a spiral gear ring on the lower portion obtains power to drive an engaged rack set to move, a clamping strip moves back and forth in a lower cover, a stepping motor obtains power and rolls in a connecting plate, meanwhile, a small hydraulic cylinder controls a movable part to stretch, and the clamping strip is driven to move back and forth. The outer surface of the gradually-changed clamp assembly makes contact with the outer surface of the pile head, the stepping motor is started to work, the center shaft is driven to rotate, then the gradually-changed column is driven to rotate, and due to the fact that the gradually-changed column is in a gradually-changed spiral shape, the outer surface with the gradually-changed radius of the gradually-changed column gradually clamps the pile head under the condition that the upper end and the lower end of the center shaft are stressed; therefore, pile heads of different sizes and shapes are clamped, subsequent pile pulling is carried out, actual use is facilitated, and the construction period is shortened.
本发明公开了一种适用于多尺寸桩头的桥梁拔桩机及其使用方法，涉及桥梁拔桩技术领域，包括缆绳收缩机构，所述缆绳收缩机构的下端套接有夹桩机构。本发明通过驱动电机工作，经过一系列传动，下部的螺旋齿圈获得动力，带动啮合的齿条组运动，使得卡条在下盖中来回移动，使得步进电机获得动力，在连接板的内部滚动，同时小液压缸控制活动部件伸长，渐变型夹具组件的外表面与桩头的外表面接触，启动步进电机工作，带动中心轴转动，进而带动渐变型柱转动，由于渐变型柱是渐变的螺旋形状，渐变型柱半径渐变的外表面在中心轴上下两端受力的情况下，逐渐夹紧桩头，由此进行不同尺寸和形状的桩头的夹持，进行后续的拔桩，便于实际的使用，节省施工周期。
