The invention relates to a double-layer vacuum chuck device of a tubular pile crane. The double-layer vacuum chuck device comprises a vacuum gas storage hanging beam, a vacuum pump, a connecting rod assembly, a vacuum chuck assembly, a gas valve, an electromagnetic valve and a three-way valve, the vacuum gas storage hanging beam is hollow; the vacuum pump is mounted on the vacuum gas storage hanging beam, is connected to the vacuum gas storage hanging beam through a main gas pipe and is used for vacuumizing the whole vacuum gas storage hanging beam; the connecting rod assembly is installed on the vacuum gas storage hanging beam, and the vacuum sucker assembly is installed at the bottom end of the connecting rod assembly. The multiple vacuum suction cup assemblies are arranged in the extending direction of the vacuum gas storage hanging beam. The vacuum suction cup assembly is provided with a large suction cup and a small suction cup, and the small suction cup is arranged in the large suction cup; the air valve and the electromagnetic valve are respectively mounted on the vacuum gas storage hanging beam; the air valve is connected with a three-way valve; the three-way valve is connected with an air pipe I and an air pipe II; the air pipe I is connected with the large sucker; and the air pipe II is connected with the small sucker. The pipe pile hoisting device has the advantages of being safe to use, low in cost, capable of being used for hoisting pipe piles with various pipe diameters and the like.
