Description

Equipment for driving gondola{Equipment for driving gondola}

The present invention relates to a gondola running facility, and more specifically, to a gondola running facility capable of not only vertical running but also left and right running (lateral running).

When building a ship, a gondola is mobilized for work at the height.

Aerial work such as painting, welding, and finishing work on the hull shell is carried out through a gondola that runs up and down in hoisting and hoisting methods.

Gondolas are usually applied to the vertical section of the ship. The vertical section refers to the part of the hull shell that falls vertically from top to bottom, visible from the side except for the bow and stern of the ship. Aerial work vehicles are usually applied to the curved section that appears at the bow or stern of the ship.

Unlike aerial work vehicles, there is a need for a gondola that is fixedly installed in a specific location for left and right running (transverse).

This is because the overall length of the ship is very large, and moving only up and down from a fixed installation position greatly limits the operator's working radius. There is a demand from workers who want to work by moving the gondola left and right a little more. It causes the risk of safety accidents by slowing down the work speed and unreasonably widening the left and right work radius.

Although the above problems can be solved by installing a large number of gondolas at once, it requires expansion of a large number of gondola equipment and workforces.

In particular, during the installation process of the gondola, the support (such as hook type, anchor type, welding type, etc.) must be installed at the top of the gondola. Re-installing the supports in a new location consumes a lot of resources.

The inventor of the present invention reached the completion of the present invention after long research and trial and error in order to solve various problems arising from allowing the gondola to run up and down as well as left and right.

An embodiment of the present invention provides a gondola traveling device capable of running up and down as well as running left and right.

The extension direction of the girder rail and the extension direction of the main ship handrail are generally the same.

Each of the girder rails is connected to each other along the extension direction to form a junction (JP). Since the junction (JP) is a connection part between the girder rails, it may be a welding or bolting fastening part. As will be described later, since the traveling device capable of traveling left and right passes through the junction, it is preferable that the girder rails are properly aligned and the junction is formed so that there is no step difference so as to move smoothly. To this end, each web portion can be utilized for bonding between the girder rails (such as a single plate member that connects the webs to each other by bolting). In addition, a stopping part ST for setting the left and right movement limit of the traveling device may be provided on the web of the girder rail. 1 and 3, the stopping part ST may be provided at both ends e1 and e2 of the girder rails, respectively.
