  Hereinafter, the present invention having the above-described configuration will be described in detail with reference to the accompanying drawings.

  As shown in FIGS. 2 to 4, the launching system for a ship according to one embodiment of the present invention includes a plurality of moving means 10 that can move while supporting a ship hull 5, and these moving means 10 are arranged in a linear direction. The guide rail 20 has a lattice structure so that the hull 5 can be selectively moved in the longitudinal direction and the width direction.

  The said moving means 10 consists of the base 11 which supports the bottom face of the hull 5, and the trolley | bogie 12 which mounts this base 11 on the upper surface, and moves using the wheel 12a.

  A hull protection unit 30 is provided between the gantry 11 of the moving means 10 and the hull 5.

  Here, it is preferable that the hull protection unit 30 is made of a wood material having a thin plate structure.

  Here, the elevating means 40 includes a cylinder 41 fixed to the upper surface of the carriage 12 and a piston rod 42 that elevates and lowers the gantry 11 while projecting up and down with respect to the cylinder 41.

  The guide rail 20 is in close contact with the ground on the bottom surface thereof, and a base plate 21 having a predetermined thickness is provided. The guide rail 20 protrudes upward from the upper surface of the base plate 21 by a predetermined height. The wheel 12a of the trolley | bogie 12 is mounted in the elongate square-bar shape which enables it to roll.

  Here, the wheel 12a of the carriage 12 preferably has a normal shaft rotation direction switching structure such as a cart so that the wheel 12a travels along the longitudinal direction of the guide rail 20 and can be easily switched in the width direction.

  Further, at both end portions in the width direction on the upper surface of the guide rail 20, there are respectively provided retaining protrusions 20a protruding upward in order to prevent the wheels 12a of the carriage 12 from separating in the width direction.

  The longitudinal guide rail 20 has a plurality of rail structures that are spaced apart from each other at equal intervals and extend over the entire longitudinal direction, and the width direction guide rails 20 are separated from each other. A plurality of rail groups are arranged along the width direction where the separated partial hulls are positioned so that the ship's head, ship center, and stern can move in the width direction, respectively. Furthermore, it has the structure arranged so that the safe distance which makes it possible to avoid the contact between partial hulls is maintained.

  Further, the plurality of rail groups of the width direction guide rails 20 are arranged in a plurality of two line rails at equal intervals so that the divided partial hulls accurately support the center of gravity of the partial hulls when moving in the width direction. It has a structure.
