The invention relates to the technical field of oil and gas pipeline steel pipe hoisting operation, in particular to a multifunctional pipe grabbing device, and aims to solve the problems that steel pipes shake and fall off when being moved and assembled, and the working efficiency is low. The device comprises a pipe holding assembly, a transverse moving assembly, a swinging assembly and a rotating assembly. The two pipe holding assemblies are installed at the two ends of the transverse moving assembly in a sliding mode and can move in the length direction of the transverse moving assembly. One end of the rotating assembly is connected with the excavator, and the other end is hinged to the transverse moving assembly and used for driving the transverse moving assembly to rotate in the horizontal plane. The other end of the swinging assembly is hinged to the transverse moving assembly; the two swing assemblies are symmetrically arranged on the two sides of the rotating assembly and used for driving the swing assemblies to swing in the vertical plane. Radial pipe loosening and embracing, vertical angle adjustment, rotation and axial moving operation of the steel pipe can be achieved, the problems that when a long-distance pipeline is installed, the steel pipe is difficult to move, and the assembling efficiency is low are solved, and the field construction efficiency is improved.
本发明涉及油气管道钢管吊装作业技术领域,尤其涉及一种多功能抓管装置,旨在解决对钢管进行移动、组对时钢管晃动、脱落以及工作效率低的问题。本发明包括抱管组件、横移组件、摆动组件和旋转组件;两个抱管组件滑动安装于横移组件的两端并可沿横移组件的长度方向移动;旋转组件一端与挖掘机连接,另一端铰接于横移组件,用于带动横移组件在水平面内转动;摆动组件一端铰接于横移组件,另一端铰接于横移组件;两个摆动组件对称设置于旋转组件的两侧,用于带动摆动组件在竖直平面内摆动。本发明可实现对钢管的径向松抱管、上下角度调节、回转及轴向移动作业,解决了长输管道安装时钢管移动困难、组对效率低的问题,提高了现场施工效率。
