Pile holding machine

Abstract

The invention discloses a pipe holding machine, and belongs to the field of wind power installation machinery. The pile holding device comprises a mounting seat, a main pushing mechanism and a clamping arm assembly. The clamping arm assembly comprises a first clamping arm, a second clamping arm, a third clamping arm, a first pile holding cylinder, a second pile holding cylinder, an opening and closing cylinder, a plurality of correction cylinder assemblies and a boom cylinder assembly. The boom cylinder assembly includes a boom cylinder, a fixed arm and a boom. When the first pile holding cylinder, the second pile holding cylinder and the opening and closing cylinder are extended, the first clamping arm, the second clamping arm and the third clamping arm are closed, after the clamping armsare closed, the elongation length of the correction cylinder assemblies is adjusted, and the verticality of a foundation pile is adjusted in time. When a certain height difference occurs when the second end of the second clamping arm and the second end of the third clamping arm are closed, the height adjustment of the second end of the third clamping arm is achieved by the boom cylinder, so thatthe second end of the second clamping arm and the second end of the third clamping arm is kept on the same plane to facilitate the connection between the second end of the second clamping arm and thesecond end of the third clamping arm, the operation is simple, and time and labor are saved.

Description

technical field [0001] The invention relates to the field of wind power installation machinery, in particular to a pile holder. Background technique [0002] my country's offshore wind energy resources are abundant, and the value of offshore wind energy is three times that of onshore wind energy, which has broad development and application prospects. Offshore wind power, as an important renewable green energy, has received widespread attention. Offshore wind turbines generally include foundation piles, transition piles and wind turbine towers arranged on the foundation piles, and wind blades of the wind turbine towers are driven to rotate to generate electricity. Due to the complicated sea conditions, it is easily affected by variable factors such as high winds, waves, ocean currents, and tides. In addition, the seabed soil is relatively soft, and the foundation piles are easily deflected during piling. The inclined foundation pile will directly affect the stability of the...
