Abstract

A lifting lug is installed at an outer plate (1) of a ship body. The lifting lug comprises a main force-receiving plate (100). A plurality of lifting holes (200) are arranged at the main force-receiving plate (100). The main force-receiving plate (100) has a first side (110) and a second side (120) which are parallel to each other. The first side (110) is welded to the outer plate (1) of the ship body. A length of the first side (110) extends in a length direction of the ship body. The lifting lug does not have a panel, and is directly welded to the outer plate (1) of the ship body. Moreover, the lifting lug has a length direction the same as the length direction of the ship body, and thus presents very little resistance in operations of the ship body. Accordingly, the lifting lug can be installed as a permanent lifting lug. There is no need to remove the lifting lug after a rudder blade or a paddle is lifted into position, thereby saving the time required for removal of the lifting lug, reducing costs, and improving performance. Arrangement of the plurality of lifting holes (200) at the lifting lug enables the lifting lug to be applied in many situations. Compared with the prior art, the invention reduces the number of lifting lugs to be installed.

Hang code

Technical field

The utility model relates to the field of lifting technology, in particular to a lifting code.

Background technique

In the berth construction mode, the stern itself has a slope, so the stern is mainly used in the form of scaffolding with outer panels. In the case of tight schedule of the rig, when the rudder blade and blade installation tooling equipment are used to assist in the installation of the rudder blade and the blade, the crane is required to be hoisted. Due to the large volume of the installation tool, a large number of scaffolds in the stern can be removed to transport the tooling equipment. And it takes up a lot of crane resources. After installing the rudder blades and blades, it needs to be re-erected, which directly increases the man-hour and cost of installing the rudder blades and blades.

For ease of installation, the rudder blades and blades are mainly used in the traditional lifting code format, instead of using tooling equipment for the installation of the rudder blades and blades. However, when using the traditional lifting code operation form, many lifting codes need to be installed on site to meet the construction requirements. The lifting code needs to be positioned and installed according to the site conditions during installation. After installing the rudder blade and the blade, it needs to be dismantled, polished, and recoated, which increases the workload and cost of installing the rudder blade and the blade.
