A steel pile tube internal expansion type pile hanger

Abstract

A steel pile pipe internal expansion type pile hanger, lifting lugs, central shaft, hollow oil cylinder, connecting seat, guiding cylinder, axially moving cone wedges, and load-bearing retaining rings are sequentially installed on the same axis to form a driving cone body; lifting lugs and hollow oil cylinder are located on the upper part of the central shaft, axially moving cone wedges and load-bearing retaining rings are located on the lower part of the central shaft; the hollow oil cylinder is connected to the upper part of the connecting seat through connecting bolts, and the guide cylinder is connected to the connecting seat through connecting bolts The lower part is connected, the balance boom is welded on the connecting seat, the central axis passes through the connecting seat; the conical surface of the axially moving cone wedge is uniformly processed T grooves, with radially moving wedges on the T beam fit ;The rectangular windows are evenly distributed around the guide cylinder, and cooperate with the radially moving wedges, The advantages are: reduced processing difficulty, easy to improve processing quality, reduced processing cycle, lower processing cost, easy to purchase, piping, installation and maintenance, the external hollow oil cylinder has a larger working area due to the external installation, and can provide larger swelling force.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a steel pile tube internal expansion pile hanger. Background technique [0002] Currently used in hoisting engineering, especially the pile hanger in marine engineering, the central axis of the cylinder barrel and the axially moving wedge are manufactured as one part. Although such a design has the advantage of compact structure, it also brings the disadvantages of complex parts, difficult processing, high requirements, many processing steps for a single part, long cycle time, high quality requirements, and difficult installation and maintenance. Contents of the invention [0003] The object of the present invention is to avoid the deficiencies of the prior art, and provide a steel pile tube internal expansion pile hanger. [0004] The technical scheme of the present invention is : A steel pile tube internal expansion type pile hanger, including lifting lugs, central shaft, hollow oil c...
