Tubular column mechanical hand

Abstract

A tubular column mechanical hand comprises a hydraulic outer shell, a hydraulic cylinder, a hydraulic rod, a bearing, a rotating outer shell, an end cover, a reset spring, a piston, a mechanical hand support, and ejector rod, an upper mechanical hand, a lower mechanical hand, grabbing telescopic rods and grabbing teeth. The hydraulic outer shell is connected with the rotating outer shell through the bearing, the hydraulic cylinder is mounted in the hydraulic outer shell, the hydraulic cylinder is connected to the hydraulic rod, the hydraulic rod is connected to the piston and the ejector rod, and the ejector rod is sleeved with a guide sleeve. The rotating outer shell is fixed to the end cover through fixing nuts, the upper mechanical hand and the lower mechanical hand are connected on the mechanical hand support through a rotating pin respectively, the upper mechanical hand and the lower mechanical hand are respectively provided with three grabbing teeth, and pressure springs and the grabbing telescopic rods are arranged in the grabbing teeth. By means of the tubular column mechanical hand, the contact area of the mechanical hand and tubular column type goods can be enlarged, the tubular column mechanical hand has the functions of anti-sliding and reducing friction loss, and improves grabbing force.

Description

technical field [0001] The invention relates to a pipe string mechanical gripper, which belongs to the technical field of mechanical hands. Background technique: [0002] At present, due to its own unique characteristics, pipelines are widely used in many industries and fields. It is mainly used in water supply, drainage, heat supply, gas supply, long-distance oil and natural gas transportation, agricultural irrigation, hydraulic engineering and various industrial devices. Most of the current manipulators have complex structures and cumbersome operations. Most of them can only grip pipes with a fixed diameter. When the diameter of the pipe changes, the force on the pipe will be concentrated, which will easily deform and damage the pipe. Invention content: [0003] The invention provides a mechanical gripper for pipe strings, which mainly solves the problems in the prior art that the structure of the manipulator is complicated, the operation is cumbersome, most of them can...
