Description

 This invention relates to shipbuilding, in particular to structures of keel-block supports.

The purpose of the invention is to increase the reliability of the support.

FIG. 1 shows the keelblock support, general view; in fig. 2 - the same view at the time of an off-center landing of the vessel; in fig. 3 - the same view from a centered vessel; in fig. 4 — node 1 in FIG. one.

The keelblock support consists of two supports 1i of unequal arms 2 and 3 pivotally mounted on supports 1, a central link 4 pivotally connected to the ends of the arms 2 and 3. The supports 1 are mounted on the base 5, the arms 2 and 3 have a solid elastic bed made of thick-walled pipes 6. The central link 4 is equipped with a movable keelblock 7 with an elastic cushion 8. The keelblock 7 is mounted on a roller holder 9. The return device of the movable keelblock 7 consists of nat 10 fixed to the movable keelblock 7 and the counterweight 11. The ropes 10 are missing h Res counter rollers 12. By central unit 4 is fixed cylindrical guide 13 movably conjugated with the other of the cylindrical guide 14 mounted on a base 5.

Guide 13 has restrictive rings 15 and 16, and direction

Track 14 Has a restrictive ring 17.

Kiloblochnaya support works as follows.

five

Uneven shoulders levers 2 and 3 are omitted, while their movement is limited by the position of the restrictive rings 15 and 17. Movable keelblock

10 7 is in the middle position due to the operation of the return device (ropes 10, counterweight 11, rollers 12). In the case of an off-center landing of the vessel, the latter, as it is seated on the keel-block support, transfers part of its weight to the central link 4, which, remaining in a horizontal position, receives a vertical movement by

20 operation of the cylindrical guides 13 and 14. Moving the central link 4 causes the levers 2 and 2 to rotate. 3 at the same angle. The lever 3, which first touches the court 25 of the vessel, moves it on the movable keelblock 7 until the other lever 2 touches and then does not perceive the equal (as well as lever 3) load from the ship's hull. In this case, the vessel is centered with respect to the axis of the keel-block support. When the vessel is massing levers 2 and 3, the keelbag support returns to its original position.
