Automatic straightening device for crane pile frame construction

The invention discloses an automatic straightening device for crane pile frame construction, which comprises a crane arm rest (1) and a pile frame (3). The automatic straightening device is characterized in that the top of the crane arm rest (1) is connected to the middle upper part of the pile frame (3) through a connecting disc rotating mechanism (2) capable of realizing left-right, and front-rear swing; the lower part of the pile frame (3) is connected to a crane lower vehicle through two diagonal bracing oil cylinders (4); and the bottom of the pile frame (3) is equipped with a ground oilcylinder (5). The automatic straightening device can realize quick straightening of the lifted and moved pile frame, and improves adaptation and operation ability, under a condition of uneven ground,of equipment. 一种起重机桩架施工自动调直装置，它包括起重机臂架（1）、桩架（3），其特征在于：所述起重机臂架（1）的顶部通过能够实现左右、前后摆动的连接盘旋转机构（2）与桩架（3）的中上部相连接，所述桩架（3）下部通过两根斜撑油缸（4）与起重机下车连接，在桩架（3）底部安装有支地油缸（5）。本发明能够实现起架、移机后桩架的快速调直，提高设备在地面不平整条件下的适应性、及作业能力。
