Technical Field

The invention relates to ship equipment, in particular to a double-layer raft frame capable of preventing accidental slipping.

Background

At present, double-layer life raft frames of ships in operation and construction are widely applied, the space is saved, the arrangement is convenient, the life rafts are thrown accidentally according to market feedback due to corrosion and aging of steel wire ropes or faults of hydrostatic pressure releasers in the ship operation process, the disposable life rafts cannot be recovered after falling into water, the economic loss of the ships is caused, the faults of the hydrostatic pressure releasers also exist, the life rafts cannot be released, and serious potential safety hazards exist.

Disclosure of Invention

The invention provides the accidental-falling-prevention double-layer raft frame which is simple in structure, stable and convenient to use, and capable of effectively preventing the life raft from being thrown off accidentally or being released due to failure and improving the use safety.

The technical scheme adopted by the invention is as follows: the utility model provides a prevent double-deck raft frame of unexpected landing type, includes unable adjustment base, fastening cable, shelves pole, hydrostatic pressure releaser, the slope direction equipartition that the lower part articulated on unable adjustment base and follow unable adjustment base in the shelves pole more than, shelves pole upper portion by the fastening cable of winding tightly on the life raft through hydrostatic pressure releaser joint on unable adjustment base, its characterized in that: the limiting rod is in a movable drawing state along the inclined direction of the inclined base in a manner of being parallel to the inclined direction of the inclined base, and the limiting rod is movably connected in a limiting hole in the lower portion of the stop rod in a penetrating manner.

And the stop lever is provided with a baffle positioned above the limiting hole.

By adopting the technical scheme, the invention has the beneficial effects that: the life raft is thrown down in the inclined direction of the inclined base by disconnecting the winding connection of the fastening rope to the life raft when the water level reaches the position where the life raft needs to be released through the hydrostatic pressure releaser in the prior art, the lower part of a blocking rod hinged on the inclined base is provided with a limiting hole, the limiting rod is connected in the limiting hole in a penetrating manner to limit the lower part of the blocking rod, the upper part of the blocking rod is prevented from rotating around a hinge joint thereof under the action of gravity to pull the hydrostatic pressure releaser to release the life raft accidentally, when the hydrostatic pressure releaser is normal and the water level reaches the position of the hydrostatic pressure releaser, the hydrostatic pressure releaser automatically loosens the fastening rope, the limiting rod is pulled by manual operation to be separated from the limiting hole at the lower part of the blocking rod, the blocking rod rotates outwards under the action of gravity, and the life; when the water inlet pressure releaser is normal and the water level does not reach the position of the hydrostatic pressure releaser, the limiting rod is pulled by manual operation, the blocking rod rotates outwards under the action of gravity, the upper part of the blocking rod drives the fastening rope to disengage the hydrostatic pressure releaser, and the life raft is thrown and released along the inclined base; when the hydrostatic pressure releaser is loosened due to faults, the stop lever prevents the life raft from being thrown off accidentally, when the life raft needs to be released, the limiting lever is pulled by manual operation to be separated from a limiting hole at the lower part of the stop lever, the stop lever rotates outwards under the action of gravity, and the life raft is thrown off and released along the inclined base; the release of the life raft is effectively controlled, so that the fixing stability, safety and use safety of the life raft can be ensured; and the baffle is arranged above the limiting hole, so that the cross-connection cross angle between the limiting rod and the stop rod after the limiting rod is in cross connection with the limiting hole can be effectively prevented from being locked, the limiting rod is prevented from being locked and deformed, the pulling is avoided, and the use safety performance is improved.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a partially enlarged view of fig. 1.

In the figure: the life raft comprises an inclined base 1, a life raft 2, a hydrostatic pressure releaser 3, a fastening rope 4, a stop lever 5, a limiting hole 6, a baffle 7 and a limiting rod 8.

Detailed Description

The following further description is made in conjunction with the accompanying drawings and examples.

Shown in FIGS. 1 and 2: a double-layer raft frame capable of preventing accidental sliding comprises an inclined base 1, a hydrostatic pressure releaser 3, a fastening rope 4, a stop rod 5, a baffle 7 and a limiting rod 8. The lower part articulates on unable adjustment base 1 and along unable adjustment base's incline direction equipartition in the shelves pole 5 of more than one, shelves pole upper portion is by winding tightly fastening rope 4 on life raft 2 through hydrostatic pressure releaser 3 joint on unable adjustment base 1, gag lever post 8 is on a parallel with unable adjustment base 1 incline direction cross-under and is can follow unable adjustment base incline direction activity pull state in unable adjustment base lower part, gag lever post 8 activity cross-under is in spacing hole 6 of shelves pole 5 lower part, be equipped with baffle 7 on the shelves pole of spacing hole top position.
