A combined piston head hanger
This utility model provides a combined piston head lifting device, belonging to the field of processing technology. It includes a lifting ring with two iron chains on its surface. A first lifting arm and a second lifting arm are respectively mounted at the other end of each chain. A mandrel is positioned between the first and second lifting arms. A base support is fixedly installed at the other end of each of the first and second lifting arms. A piston head body is positioned between the first and second lifting arms. The lifting ring and iron chains are welded together, and the iron chains are welded to both the first and second lifting arms. The first and second lifting arms are cross-connected, and the mandrel is located at the intersection point. This utility model utilizes the gravity generated by the piston head body during lifting. Its own weight causes the hinge formed by the first and second lifting arms and the mandrel to clamp tightly, further ensuring that the base support is firmly engaged in the annular groove on the surface of the piston head body under the clamping force, thus improving the stability and safety of the piston head body during lifting.
