Description

≪ Desc / Clms Page number 1 > apparatus for laying cable &

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable laying apparatus, and more particularly, to a cable laying apparatus capable of laying a cable while moving along a cable tray.

A cable tray is usually provided to connect a wire cable to each location where electrical supply is required when a building is to be expanded or contracted. A cable tray is a structure made of metal or non-combustible material to support a cable, and several cables are laid on the cable tray in a bundled state.

In the case of ships, too many cables are laid on cable trays for power supply or inter-device connections. Cable installation works include installation of cable trays inside and outside the ship during the ship's construction and laying of multiple cables in the cable tray. At this time, the cable tray may be provided in multiple stages and may include a curved portion. Cables installed on ships vary in their type and size. Depending on the type of ship, cables may be installed several hundreds of thousands meters or more, and their weight may exceed tens of thousands of tons.

Thus, cable laying is an important part of ship construction. In the conventional cable laying method, the rope is connected to one end of the cable before the cable is laid, the rope is moved to the winch on the cable tray, and the cable connected to the rope is indirectly wound by using a winch It was installed in a cable tray. However, a separate work process was required to connect the rope to the winch, and thus the work time was increased. In addition, when a winch is used, there is a problem that a tension greater than an allowable range is applied to the cable or a frictional force acts between the cable and the cable, thereby damaging the cable. To solve this problem, a method of using a pusher has been proposed, but there is a problem that the space for installing the pusher is limited.

In addition, in the area requiring large power despite the winches and pushers, or in the narrow space where it is difficult to install such equipment, the operator had to manually install the cable.

However, the cable installation by the manual operation of the operator not only consumes manpower and cost but also causes the musculoskeletal diseases of the worker. In addition, there is a problem that it is difficult to work through a manual operation in a narrow space or a zone where a cable tray is installed in multiple stages.

The pulling portion includes a hook portion which is fitted in a mesh-type cable armor (C1) and fixes the cable so as not to come off from the pulling portion. A plurality of hooks 220 may be arranged in a line along a third direction in front of the bottom plate 210 to pull up a plurality of cables with a bundle. The hook portion 220 includes a wire 222 and a hook 224 and the hook is installed at the end of the wire 222 and is fitted in a mesh type cable arm C1.

The first air tube 230 is provided on the upper surface of the bottom plate 210 to prevent damage to the cable due to an impact applied to the cable C when the cable is installed. The cable C to be installed is placed in the first air tube 230 and fixed by the hook portions. The second air tube 240 is placed on top of the cable C. That is, the second air tube 240 is provided between the binder 260 and the cable C to prevent cable damage.

According to the above configuration, the cable installation device 10 of the present invention is configured such that the cable C is pulled in a state in which the lower portion and the upper portion are wrapped by the first air tube 230 and the second air tube 240, It is possible to prevent cable damage which may occur.

The binder 260 binds the cables C fixed to the hooks 220 to the bottom plate 210. The binders 260 may be installed on both sides of the bottom plate 210, respectively. The binder 260 may be made of a flexible material and may include fixing means such as a ball screw to be coupled with each other. When the upper portion of the cable is tightly tightened using the binder 260, the second air tube 240 is pressed onto the upper surface of the cables, and the cable C is pressed with high adhesion force between the cables C and the first and second air tubes 230, Can be tightly fixed. In addition, a rubber mat 250 may be mounted between the binder 260 and the second air tube.
