Abstract

This invention discloses a mechanical pipe-picking and releasing device, a pipe decommissioning device, and a method, which can automatically grip and release pipes under the action of a robotic arm, thereby reducing the complexity of equipment and operation during pipe decommissioning. The mechanical pipe-picking and releasing device includes a support pipe, a clamping assembly, and an elastic compression assembly. The support pipe is mounted on the robotic arm and moves under the action of the robotic arm to move the clamping assembly. The clamping assembly is located on the telescopic end of the support pipe and has a clamping opening capable of clamping and opening. The elastic compression assembly is located inside the support pipe and connected to the clamping assembly. It can extend and retract within the support pipe to continuously apply a first force in a first direction to the clamping assembly, causing the clamping opening of the clamping assembly to tend to maintain a clamped state; the first direction is the direction from the support pipe to the clamping assembly.
