Pile top pushing and positioning device

Abstract

The invention discloses a pile top pushing and positioning device. The pile top pushing and positioning device comprises a pile top positioning base. A positioning groove matched with the pile top of an engineering pile is formed in the bottom of the pile top positioning base. A supporting frame is arranged above the pile top positioning base. A lifting adjustment device is connected between the supporting frame and the pile top positioning base. A three-direction jack and a locking device fixed through cooperation with a bottom plate of a bearing platform are fixed to a top plate of the supporting frame. The pile top positioning device and the pile top are matched and positioned through the pile top positioning device. The height of the supporting frame is adjusted through the lifting adjustment device. The bearing platform is locked through the locking device. When the bearing platform needs to be moved, the platform is pushed out and moved through the three-direction jack. The pile top pushing and positioning device is convenient to operate, simple in structure and high in stability. Mobility of the platform is achieved. Meanwhile, the construction requirement of the engineering pile within a large range is met through mobility of the platform, the construction efficiency is greatly improved, the work quantity of workers is decreased, and good practicability and high market application value are achieved.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction equipment, in particular to a pile top pushing positioning device. 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 it is very convenient t...

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.
