Folding clamping mechanism and tube rocking machine
The folding type clamping mechanism comprises an outer clamping unit, an inner clamping unit arranged on the inner ring of the outer clamping unit and a clamping oil cylinder, the two ends of the clamping oil cylinder are hinged to the outer clamping unit through oil cylinder pin shafts, and the clamping oil cylinder is controlled to enable the outer clamping unit and the inner clamping unit to be closed in the horizontal direction to form a closed annular clamping space; the outer clamping unit comprises two first arc-shaped frames, two second arc-shaped frames, two third arc-shaped frames and a connecting frame which are mutually hinged into a whole; a first inner hoop, a second inner hoop and a third inner hoop of the inner clamping unit are mounted on the inner cambered surfaces of a first arc-shaped frame, a second arc-shaped frame and a third arc-shaped frame; the hinged inner folding and outer clamping units are adopted, rapid conversion from a working state to a transportation state is achieved, the width size is effectively reduced, the storage space is effectively saved, and the road transportation requirement is met; and the multi-section type inner hoop is arranged, so that the clamping gap between the clamping mechanism and the steel cylinder well is reduced, the clamping effect of the clamping mechanism is effectively improved, and the downward pressing operation efficiency of the steel cylinder well is improved.
一种折叠式夹持机构及摇管机，包括外夹紧单元、置于外夹紧单元内圈的内夹紧单元、及两端分别通过油缸销轴与外夹紧单元铰接的夹紧油缸，操控夹紧油缸使外夹紧单元、内夹紧单元在水平方向围拢形成封闭的环状夹持空间；外夹紧单元包括相互铰接成一体的两个第一弧形架、两个第二弧形架、两个第三弧形架和一个连接架；内夹紧单元的第一、第二、第三内抱箍安装于第一、第二、第三弧形架的内弧面；本发明采用铰接内折叠外夹紧单元，实现工作状态到运输状态的快捷转换，使宽度尺寸有效收缩，有效节省仓储空间和满足道路运输要求；采用多段式内抱箍设置，减少与钢筒井之间的夹持间隙，有效改善夹持机构的夹持效果，提高钢筒井下压作业效率。
