The further technical scheme is that the first structure comprises a plurality of through holes which are arranged on the vertical plate at intervals. Therefore, when the ship is launched, the water resistance is not too large due to the arrangement of the cross arm, and the water resistance is reduced.

The rubber air bag is fixedly connected between the two plates, and the partition plate is fixedly connected between the upper plate and the lower plate of the vertical plate, which are oppositely arranged. After the arrangement, the rubber air bags are inflated and filled at the beginning of the launching of the ship, then the bow and the stern of the ship are placed on the cross arm and then are rapidly deflated, so that one end of the ship close to the water surface sinks, the launching process of the ship is accelerated by utilizing the gravity center, the sinking and the dead weight, and the launching efficiency of the ship can be improved.

And this process is more rapid than the previous deflation protocol.

A further technical scheme is that one end of the sliding rail of the height increasing portion is provided with a positioning pin hole, an entity cylinder is fixedly arranged on the inner side wall of the vertical plate, a telescopic air bag is fixedly connected below the entity cylinder and is arranged in the vertical direction, the telescopic air bag is arranged right above the positioning pin hole, a through hole used for the telescopic air bag to pass through is formed in a horizontal plate of the bottom surface of the vertical plate, and the size of the through hole is larger than that of the positioning pin hole. Therefore, the telescopic air bag is filled with air at the beginning to realize the function of serving as a positioning pin, the rising part and the vertical plate are ensured to be in the relationship of the upper position and the lower position without deviation, then the rising part and the vertical plate are deflated, the time for inflating and deflating is short because the size of the telescopic air bag is not large, the telescopic air bag is deflated after the bow and the stern of the ship are arranged on the cross arm, and the rising part slides backwards along with the process of launching the ship, namely the rising part slides towards the water surface, until the rising part is arranged behind the vertical plate and moves upwards, so that the sinking of one end of the ship close to the water surface is realized, and the launching process of the ship is accelerated.

The invention has the advantages and beneficial effects that: the rubber air bag is inflated to be full at the beginning of the launching of the ship, then the fore and the aft of the ship are placed on the cross arm and then are deflated rapidly, so that one end of the ship close to the water surface sinks, the launching process of the ship is accelerated by utilizing the gravity center, the sinking and the dead weight, and the launching efficiency of the ship can be improved. The friction force between the cross arm and the slide way can be reduced, the ship can be launched conveniently, in addition, the anti-slip layer can ensure the connection between the ship and the cross arm to be firm, and the launching speed can not be influenced by the relative sliding between the ship and the cross arm.
