The invention discloses a vertical hoisting clamp for a heavy barrel. In the process of hoisting the barrel, an electromagnet is powered on so as to attract a magnet armature to enable the magnet armature to be combined with the electromagnet, and an ejection rod pushes a lower disc compress spring, so that a friction block shrinks inwards, and a hoisting tool is put into the barrel at the moment; when the electromagnet is powered off, the spring resets, so that the friction block unfolds outwards and is clamped on the inner wall of the barrel; when a hoisting rod is pulled, due to the action of gravity, the force of the friction block pressing into the inner wall of the barrel is further increased, and the clamp can work safely due to the force action and the automatic balance effect, so that the heavy barrel can be hoisted to a preset position. According to the vertical hoisting clamp, the electromagnet is used as an opening and closing driving mechanism of the clamp, so that the safety performance is relatively good, the operation is relatively convenient, the pollution to the environment is not prone to cause, the maneuverability is relatively good, the use is convenient, and the defects that the pollution to the environment is easy to cause, the maneuverability is relatively poor, and the use is inconvenient in the prior art are overcome.
