Pipe grabbing device
A pipe grabbing device comprises a connecting base, a swing mechanism, a body and a pipe grabbing mechanism, wherein one end of the swing mechanism is connected with the connecting base, the other end of the swing mechanism is connected with the body, and the pipe grabbing mechanism is hinged to the body. The pipe grabbing mechanism comprises left grabbing parts, right grabbing parts, hydraulic oil cylinders and synchronous connecting rods, the left grabbing parts, the right grabbing parts, the hydraulic oil cylinders and the synchronous connecting rods form four-bar mechanisms to grab a pipe, and a fitting fork is arranged on the body and matched with the pipe grabbing mechanism to fit and hold the pipe in a multi-fulcrum and long-span mode. The pipe is held by adopting 360-degree adjustment of hydraulic swing, grabbing of the four-bar mechanisms and multi-fulcrum long-span cambered surface fitting, pipelines, telegraph poles and the like can be carried and installed through engineering machines, and the pipe grabbing device has high efficiency, reliability and practicability.
