Description
Technical field
The present invention relates to a kind of sea-freight outer casing door, particularly a kind of marine vessel outer casing door.This outer casing door comprises the framework that comprises door-plate.This framework provides skeleton structure for described outer casing door.Described door-plate can be connected to doorframe movably.
Background technology
All outer casing doors in the hull of boats and ships are all obeyed special safety requirements.Especially, when the lower area under outer casing door is positioned in the floating line of boats and ships.In specifying, SOLAS defines intensity and the fixing and locking layout of the outer casing door on ro-ro passenger ship.SOLAS has carried out revised after being defined in Estonia's ferryboat generation major accident.Point out that about the official report of this accident lock on bow door is because the strain of wave was lost efficacy, door separates with the other parts of ship.It is highly important that, lock bolt did not all lose efficacy in all cases and worked on.The hydraulic operation that has confirmed lock bolt provides failure-free solution and reduces the risk of outer casing door fault.
DE202006020570U1 discloses a kind of outer casing door, and this outer casing door is provided with multiple hydraulic action lock bolts.This lock bolt axially can move and operate by hydraulic actuating cylinder.Multiple lock bolts are provided at the periphery of outer casing door.Central authorities' pump is provided for operation hydraulic actuating cylinder.Fluid line is provided for central pump is connected communicatively with hydraulic actuating cylinder fluid.
A shortcoming under this background is that fluid line extends along long path.Fluid line extends through several compartments of framework.To arrive the cylinder of outer casing door periphery.Fluid line is vulnerable to damage.In the length of life of boats and ships, the oxidation of fluid line may cause leaking.Sometimes,, when fluid line is during by accidental impact, fluid line may be blocked at least partly.Just in case leak, the entire contents in central pump may leak in environment, entire contents may be the hydraulic fluid of 30 liters of volumes.This leakage on boats and ships causes environmental pollution conventionally.
DE1.281.292 discloses a kind of hatch cover for boats and ships, comprises a pair of the first hatch cover part and the second hatch cover part, and this can be located pivotally and can pass through hydraulic force actuation hatch cover part.The first hatch cover part comprises driver element, and driver element comprises electrical motor, pump and the holder for hydraulic fluid.Driver element is arranged to drive the hydraulic actuating cylinder in the second cover.Driver element is positioned in the first fully sheathed case in the first hatch cover part.Fully sheathed case is provided as preventing any leakage of the oily cover from boats and ships to tonnage.Hydraulic actuating cylinder is disposed in the second fully sheathed case of the separation in the second hydraulic cover part.Fluid line is provided as connecting two casees, so that driver element is connected communicatively with cylinder fluid.Fluid line between the case of two separation extends through protection guide portion, and this protection guide portion is soldered to case to prevent the destruction of fluid line.This destruction may cause oily leakage.
Leak into the risk of the tonnage of boats and ships although fully sheathed case can reduce oil, described scheme is not still gratifying.
Summary of the invention
Overall object of the present invention is to eliminate above-mentioned shortcoming at least partly and/or a kind of replacement scheme of energy use is provided.More specifically, the object of this invention is to provide the failure-free hydraulic operation sea-freight outer casing door that a kind of SOLAS of meeting specifies.
According to the present invention, this object is implemented by sea-freight outer casing door according to claim 1.
According to sea-freight outer casing door of the present invention, be also referred to as ship housing door, comprise the framework that comprises door-plate.Framework provides skeleton structure, to strengthen outer casing door.Typically, framework comprises multiple compartments.
