A mechanical claw arm for pipe grabbing

Abstract

The invention discloses a mechanical gripper arm used for grabbing pipelines. The mechanical gripper arm used for grabbing pipelines comprises a sleeve pipe, a supporting pedestal, gripper main bodies, and telescopic rods; a hydraulic rod is arranged in the sleeve pipe; the lower end of the hydraulic rod is arranged outside the pipe end of the sleeve pipe; the external side of the hydraulic rod issleeved with a spacing ring; the rod end of the hydraulic rod is provided with a fixing groove; one end of a connecting rod is provided with a fixed pin; the fixed pin is arranged in the fixing groove; the bottom of the supporting pedestal is provided with a pad; the supporting pedestal is connected with the spacing ring through an elastic component; the edge end of each gripper main body is provided with a first rotating shaft; each gripper main body is connected with the pipe end of the corresponding sleeve pipe through the corresponding first rotating shaft; the internal side of each gripper main body is provided with a pad strip; the top of each gripper main body is provided with a slide groove; one end of each telescopic rod is arranged in a corresponding slide groove. The mechanicalgripper arm is suitable for grabbing of pipelines of different cross section diameters, pipeline grapping is firm, and shaking or dropping of pipelines in grabbing process is avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a mechanical claw arm for pipe grabbing. Background technique [0002] The mechanical claw arm is a mechanical device that grabs, fixes and transports objects under the action of the power system. The mechanical arm has a wide range of uses, and generally only needs point control; that is, the parts to be transported do not have strict requirements on the trajectory, only the starting point is required and the end point pose are accurate. [0003] However, when the existing mechanical claw arm grasps the pipe-shaped equipment parts, the grasping and fixing of the tubular object is not firm, and it is easy to cause loosening and falling off of the tubular object when grasping, damaging the pipeline and posing construction safety hazards. In view of the above problems, it is urgent to carry out innovative design on the basis of the original mechanical claw arm. Cont...

Problems solved by technology

[0004] The object of the present invention is to provide a mechanical claw arm for grabbing pipes to solve the above-mentioned background technology. It is proposed that when the existing mechanical claw arm grabs pipe-shaped equipment parts, the grasping and fixing of the tubular object is not firm, and it is easy to cause tubular objects. Loosening and falling off when objects are grasped, damage to pipelines and potential safety hazards in construction
