The present application relates to a kind of
pipe string
manipulator clamp device capable of only grabbing single tubular column, belong to the tubular column automatic technology field of oil and gas drilling equipment.The clamp device is by increasing the main finger driving
hydraulic cylinder piston guide mechanism, lateral load is borne by guide mechanism, avoid the radial load that main finger driving
hydraulic cylinder piston rod is subjected to, improve the service life of main finger driving
hydraulic cylinder and the security of clamp device operation;Increase the
pipe blocking mechanism driven by connecting rod
assembly in the clamp device, when main finger driving hydraulic cylinder is contracted to the shortest, the
maximum size of jaw depth space, can realize the clamp device holding
maximum diameter pipe column, when main finger driving hydraulic cylinder is stretched to the longest, the minimum size of jaw depth space, can realize the clamp device holding minimum
diameter pipe column, realize the same clamp can hold pipe column of different
diameter function, ensure that the clamp cannot simultaneously hold the condition of two pipe columns, realize the purpose of
fully automated mechanical hand pipe string operation.
