The invention discloses a single-cylinder latch device, a cylinder head assembly and a crane, and relates to the field of engineering machines. The single-cylinder latch device, the cylinder head assembly and the crane are used for optimizing the structure of an existing cylinder pin driving mechanism and the structure of an existing arm pin driving mechanism. The single-cylinder latch device comprises a driving oil cylinder, cylinder pin guide rails used for driving a cylinder pin to move, arm pin guide rails used for driving a dovetail groove part to move and a restoration element. A first piston rod of the driving oil cylinder is connected with the cylinder pin guide rails in a driving manner, and a second piston rod of the driving oil cylinder is connected with the arm pin guide rails in a driving manner; and the first piston rod and the second piston rod are both connected with the restoration element. The restoration element is used for driving the driving oil cylinder to be restored when the driving oil cylinder is in the pressure reducing state. The whole single-cylinder latch device can be arranged outside a cylinder head body, and installing and maintaining of the single-cylinder latch device are simplified.
