The invention discloses a hollow pile gripper and a gripper system. The hollow pile gripper comprises a gripper installing base and a lifting hook assembly installed in the gripper installing base, and further comprises traction ropes and force exerting devices for winding and unwinding the traction ropes and exerting certain tensile force on the traction ropes in the winding and unwinding processof the traction ropes. One end of each traction rope is wounded on the corresponding force exerting device, and the other end is a free end. The two force exerting devices are fixed to a top plate ofthe gripper installing base and located on the two sides of the middle line of the top plate. The free ends of the two traction ropes are connected with each other to form a tensile force acting point. When traction force is exerted on the tensile force acting point, the tensile force acting point is located on the central plane in the width direction of the hollow pile gripper. The hollow pile gripper can effectively restrain rotation and ensures the work stability.
本发明公开了一种空心桩抓具及抓具系统,包括抓具安装座和设置在抓具安装座中的吊钩组件,还包括牵引绳和用于收放牵引绳并当收放牵引绳过程中对牵引绳施加一定拉力的施力装置;牵引绳一端缠绕在施力装置上,另一端形成自由端;施力装置具有两组,两组施力装置固定在抓具安装座的顶板上,且两组施力装置位于顶板中线的两侧;两组牵引绳的自由端相互连接形成拉力作用点,当在拉力作用点上施加牵引力时,拉力作用点位于空心桩抓具宽度方向的中心面上,本发明公开的空心桩抓具可以有效的抑制转动,保证了抓具工作的平稳。
