Description

The invention relates to shipbuilding, in particular to ship devices for launching rescue equipment. A ship device for launching rescue means is known, comprising a boom with a suspension for rescue means, a descent-lifting drive with a descent speed control mechanism, a landing pad and a reset device for restarting the descent cycle, the boom being mounted rotatably on the axis , inclined towards the side of the vessel 1.. However, such a ship device for launching rescue means has little reliability and safety of operation. The purpose of the invention is to increase the reliability and safety of the operation of the ship device for launching rescue equipment. The goal is achieved by the fact that the ship's device for launching life-saving appliances is equipped with guides mounted on the boom, a counterweight and locking position of the landing pad, the gunner; straight in shape in longitudinal section, the suspension is mounted on a trolley that is mounted in guides the booms are movable and connected with the return route to its original position, the landing pad is mounted hingedly with the possibility of being inclined toward the side of the ship, and the counterweight is mounted and the end of the landing area, the opposite side of her mood. In addition, the trolley return drive to its initial position contains a hand-operated winch, and the landing gear position lock is provided with locking elements for fixing its inclination relative to the deck level of the vessel at an angle from -10 to + 10 °. FIG. 1 shows the device in the working position, general view, the rescue tool is installed on the elevated landing site; in fig. 2 - the same, the landing pad is unlocked, the trolley with life-saving equipment is brought overboard; in fig. 3 is a view A of FIG. one.

The device, mounted on the boat deck of the vessel, contains an arrow 1 ,. imexnukuh possibility of rotation around the axis 2, fixed in the housing 3, installed on the ship's foundation. The arrow 1 has the shape of an I-beam and serves as a base for the cart 4 with suspension 5, on the pulleys of which a cable 6 of the winch 7 is stocked, equipped with a centrifugal brake. The cart 4 is connected via a cable 8 to a hand winch 9, which serves to move the cart 4 along the boom 1.

Platform 10 includes a landing pad 11, hingedly connected to it and equipped with a counterweight 12, intended to return the landing pad 11 to its original position for repeated descent cycle.

The landing pad 11 is used to install the raft 13 on it. On the fixation of the landing pad in three positions at angles of 10, 0 and -10 ° to the plane of the deck, there are stopper elements 14 of the retainer.

Pad 11 on the side has a folding; guard rail 15. On the platform (10 storage racks 16 for storing containers with life-saving appliances, such as rafts, are installed.

The device works as follows. The platform 11 is fixed in one of three positions at an angle of 10, 0 or -10 ° to the deck of the vessel, depending on its crepe.

The container with the first raft from the rack 16 is rolled onto the platform P, opened. And the raft 13 is filled with air. The boom 1 is unfastened and, due to the inclination of the axle 2 in the direction of the bead of the axle 2, it rotates from a position of 11 1 to the board under the influence of gravity. The carriage 4, moving along the boom 1, is installed above the raft 13 by means of a winch 9, and the suspension 5 is connected to the raft bracket 13. After the people are seated in the raft, the platform 11 is uncoupled. Under the force of gravity of the raft 13, the platform 11 is lowered to the lower position, and the carriage 4 with the raft is extruded overboard the vessel. After that, the winch 7 is launched rafting. After releasing the suspension 5 from the raft winch 7

the suspension 5 is lifted, and with the winch 9 the trolley 4 is returned for the next raft. After the first raft has descended from the platform 11, the counterweight 12 returns it to its original position, and after fixing the platform, the cycle repeats.

Claims (3)

1. A ship device for launching life-saving appliances containing an arrow with a suspension for life-saving means, a drive for launching-lifting the suspension with a mechanism for adjusting the speed of descent, a landing pad and a mechanism for returning the device to its original position, the boom being installed with the possibility of turning the axis inclined in shipboard side, different However, in order to increase the reliability and safety of operation, it is equipped with guides mounted on the boom, a counterweight and locking position of the landing pad, the boom is made straight in shape in longitudinal section, and mounted on a trolley mounted on the boom With the possibility of movement and associated with the drive to return it to its original position, the landing gear is pivotally mounted with the possibility of tilting towards the ship’s side, and the counterweight is mounted at the end of the the opposite side of her inclination. 2. A device of claim 1, characterized in that the drive for returning the cart to its initial position contains a hand-operated winch. 3. The device according to claim 1, that is, that the lock of the landing gear is provided with locking elements for fixing its position on the deck deck of the vessel at an angle from -10 to + 10 °.
