The invention discloses a spring buffering device for a tubular pile crane. The spring buffering device comprises a crane body, a hoisting adjusting mechanism is mounted at the top of the crane body and comprises a hoisting platform, the bottom of the hoisting platform is rotationally connected with the top of the crane body through a rotating shaft, a rotating hanging rod is horizontally arranged in an inner cavity of the hoisting platform, a hoisting rope winds around the outer wall of the rotating hanging rod in a sleeving mode, a motor mounting plate is fixed to the side wall of the back of the hoisting platform, a servo motor is mounted at the top of the motor mounting plate, a first electric telescopic arm rod is fixed to the outer side wall of one end of the hoisting platform, a mounting shaft sleeve is fixed to the telescopic end of the first electric telescopic arm rod, and a second electric telescopic arm rod is mounted on the side wall of the outer end of the crane body. The device is provided with a buffering spring, the situation that in the hoisting process, collision occurs, and consequently the clamped part of a building object is damaged or broken is effectively prevented, and in the strong wind and severe weather, the building object is effectively prevented from shaking in the hoisting process.
