Embodiment Construction

[0027] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments. In the following embodiments, the heavy-duty hoisting rigging and the column hoisting of a semi-submersible lifting platform are taken as an example (4 hoisting points are selected) to describe the tooling structure, system and method of the present invention in detail. However, it can be understood that this is not a limitation of the present invention, and the tooling structure, system and method of the present invention are also applicable to the installation of other hoisting slings, and the hoisting point of the suspended object is not limited to There are 4, and the distribution of its lifting points is not limited to symmetrical distribution. According to the structure of the actual suspended object, the number and distribution of its lifting points can be designed differently.

[0028] Such as Figure 2A As shown, the structure of a pre...

Abstract

The invention discloses a tool structure used for installing lifting rigging, a system and a method. The tool structure comprises a support with a plurality of end parts, wherein the end parts are corresponded with a plurality of suspension points on a suspended substrate, and end part forms an accommodation space for accommodating a rope of the lifting rigging; and a plurality of hangers arranged on the support, wherein a suspension hole is provided on each hanger. The system for installing the lifting rigging comprises the tool structure, a crane, a wire rope and a chain block, the wire rope is connected to a suspension hook of the crane, the chain block is connected to the tool structure and the wire rope, wherein, the chain block can upwardly move the tool structure to a first position in a vertical state at the bottom of the rope for conveniently connecting to the suspended substrate, or the chain block can downwardly move the tool structure to a second position in a free relax state at the bottom of the rope, so that lateral extrusion is not provided while the tool structure is lifted.

Description

technical field [0001] The invention relates to the field of large hoisting operations, in particular to a tooling structure, system and method for installing heavy hoisting slings. Background technique [0002] In recent years, with the vigorous development of offshore engineering equipment manufacturing, the weight records of large-scale hoisting have been continuously refreshed. With the increase of the hoisting weight, the diameter and weight of the hoisting rigging are also increasing, and the weight of a single rigging can reach several tons. It is heavy and subjected to lateral tension, and generally requires a crane to assist in the installation. Usually, for obliquely stressed heavy-duty hoisting slings, the small hook attached to the crane itself is required for auxiliary installation, or another crane is used for auxiliary installation. [0003] Such as figure 1 As shown, it is a schematic diagram of a system for heavy lifting rigging installation in the prior ...
