The invention discloses a pile top supporting walking type moving piling platform which comprises a pile top ejecting and positioning device fixed to the top of a steel pipe pile. A bearing platform is fixed to the pile top ejecting and positioning device. An operation platform is fixed to the bearing platform. A large bent frame guide frame is fixed to the front part of the operation platform. Two small bent frame guide frames are fixed to the left side and the right side of the bearing platform respectively. Installation platforms are fixed to the positions, corresponding to the steel pipe pile, of the front side and the rear side of the bearing platform. Walking-type ejecting forward moving of the pile top supporting walking type moving piling platform is achieved through a three-directional jack of the pile top ejecting and positioning device. The steel pipe pile can be quickly and accurately positioned through the cooperative work of a lifting adjusting device, the three-dimensional jack, the large bent frame guide frame and the small bent frame guide frames, construction of the steel pipe pile in the whole platform range can be achieved through transverse moving of the guide frames, and assembling and disassembling of the pile top ejecting and positioning device and subsequent pile top construction can be quickly achieved through the installation platforms.
