Problems solved by technology

As a special equipment, the jack-up platform can adapt to piling operations in different water depths and wave environments, but it is expensive and requires professionals to operate, and the displacement is greatly affected by the wave cycle, and it takes a long time to move and position. It is also affected by the sea environment. Large, the positioning accuracy is not high during each position conversion, and the work efficiency is relatively low; when the fixed platform is used as the foundation for engineering pile driving, the positioning accuracy is high, and it is very convenient to perform position conversion within the platform range, but the large-area fixed platform The construction cost is high, the scope of application is narrow, and only piling operations within the scope of the platform can be carried out, and the environmental adaptability is poor. Generally, it is only used in the environment of inland rivers and lakes, and it is impossible to build platforms in harsh environments such as open seas.

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction equipment, in particular to a walking-type mobile piling platform supported by pile tops. Background technique [0002] In the construction of pile foundations on water, the self-elevating platform or the fixed operation platform erected are usually used as the foundation for the construction of engineering piles. As a special equipment, the jack-up platform can adapt to piling operations in different water depths and wave environments, but it is expensive and requires professionals to operate, and the displacement is greatly affected by the wave cycle, and it takes a long time to move and position. It is also affected by the sea environment. Large, the positioning accuracy is not high during each position conversion, and the work efficiency is relatively low; when the fixed platform is used as the foundation for engineering pile driving, the positioning accuracy is high, and ...
