Truss type spud leg single slice lifting slings

Abstract

A truss framed leg single sheet sling is provided with a pad eye; adapter plates vertical to the pad eye are welded to both sides of the pad eye; the middle parts of the extension parts of two adaptor plates of the pad eye are provided with semi-round gaps corresponding to the outside of a bracing tube of the framed leg single sheet; the adaptor plates on the left and the right sides of the semi-round gaps are provided with connecting plates vertical to the adaptor plates; the connecting plates are provided with connecting holes; the pad eye includes an upper pad eye and a lower pad eye which are to the opposite with each other; the connecting plates of the upper and the lower pad eyes are in parallel with and to the opposite of each other, and are respectively connected with bolts going through the connecting holes. In this way, the connecting plates of the upper and the lower pad eyes are clamped on the bracing tube of the framed leg single sheet in parallel and to the opposite, and the bolts go through the connecting holes to fix and connect the upper and the lower pad eyes to the bracing tube of the framed leg single sheet. A hook pins the pad eye to hoist the framed leg single sheet, and grapple the upper and the lower pad eyes to turn the framed leg single sheet.

Description

Technical field:

[0001] The truss-type pile leg single-piece spreader is a special tool for the segmented lifting of the triangular pile leg single-piece assembly of the self-elevating drilling platform. The lifting of the section turned over. Background technique:

[0002] The existing segmental hoisting of the hull adopts a series of standard eye plates, and the eye plates must be welded on the hoisted body when in use. According to the requirements of the owner, the pile legs of the jack-up drilling platform are segmented. Welding rings or eye plates are not allowed on the structure, which makes it difficult to lower the tire and turn over in segments. Therefore, an alternative device must be designed. Invention content:

[0003] The present invention is to solve the problem that the hoisting eye plate of the single-piece leg of the self-elevating drilling platform cannot be welded on the single piece of the pile leg, and provides a method to ensure the safety of the l...
