Abstract

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.

Description

technical field [0001] The invention relates to the technical field of hollow pile grabbers. Background technique [0002] Hollow piles are widely used in engineering construction, but due to their large volume and heavy weight, when hoisting and transporting hollow piles, they need to be hooked by driving through the hollow pile gripper, and then transported. The pile gripper has the following problems. When driving the hollow pile gripper to move, the hollow pile gripper is prone to rotation. The rotation of the gripper will cause unstable lifting and accidents. When using the gripper to hook the hollow pile When hanging, the rotation of the gripper will cause difficulty in the hooking of the hollow pile. Contents of the invention [0003] The invention provides a hollow pile gripper, which solves the problem of rotation of the existing hollow pile gripper. [0004] The technical means adopted in the present invention are as follows: [0005] A hollow pile gripper, co...
