Description

The rotating mechanism of cargo ship hatch cover

The present invention relates to the rotating mechanism of cargo ship hatch cover, this mechanism is placed in the top of freighter cargo hold companion way, described mechanism is used to rotate at least one hatch parts from the approximate horizontal state to vertical substantially state or opposite action, and described rotating mechanism installs on aboard ship the rigid support with being rotated, and an end of described rotating mechanism is rotationally coupled on the rotating mechanism actuator devices such as hydraulic actuating cylinder.

Usually, closed with a hatch cover during the feeder hatch of cargo hold rides the sea at least, described hatch cover comprises that typically two or more are as four hatch assemblies.Hatch assembly is generally linked together mutually rotationally by a hinge, and the edge by the plug hatch device reaches and resists boisterous protective action at least.In the hatch cover closed condition, this hatch cover apparatus essentially horizontally and mutually closely is in line, to cover whole openings of hatch.The hatch cover fitness for purpose of four or more a plurality of hatch assemblies has the actuator of two separation, wherein first rotates two first vertical hatch assemblies near first actuator, the device of two ends need pull to the edge of hatch simultaneously with the actuator guiding thus, and next step makes hatch assembly reach rotating mechanism.Then, rotating mechanism is driven under the effect of second actuator, and device by previous stacking of hatch assembly that it rotates two ends erects.At the state that hatch cover is opened fully, hatch is handling goods fully freely.As an example, above-mentioned explanation is to relate separately to one first actuator, rotating mechanism and actuator thereof.Yet in fact such layout is set at the both sides of hatch.In the above-described embodiments, rotating mechanism and actuator thereof are placed on the external margin place near coamings usually.Yet, under the situation of practical operation, the particular problem that runs into be device to be arranged in the clear area between coaming and the walking channel on the side of ship be quite narrow, particularly since on the ship these zones often narrow down and obstacle such as hoist frame, pan straddle or a rotating gangway ladder representative type are in these positions.In such place a hatch cover rotating mechanism is installed, the area around the sideboard must be widened, and unique like this may be that hatch is narrowed down, and ship broadens or reduces required size is set on described zone.

An object of the present invention is to propose a kind of rotating mechanism that can overcome above-mentioned defective.Rotating mechanism of the present invention is characterised in that rotating mechanism is different from the front and back end that prior art is assembled in coaming, but be contained in the horizontal of ship and vertically go up coaming inboard to the small part cargo hold, the pivot of rotating mechanism and actuator devices are placed in the outside of coaming so that the cover plate of lifting rotating mechanism end is under the hatch cover thus, promptly are not interposing in the space that also is not arranged in the cargo hold within the hatch cover structure.Therefore, rotating mechanism needs no support in the zone between the side board of coaming and ship, and this point is the important aspect that is better than the common arrangement mode.The present invention provides an important improvement to be not being located at the special protection of the rotating mechanism on the pavement again.Of the present invention one preferably benefit be to arrange the cargo space of not occupying any preciousness.

A most preferred embodiment of the present invention is characterised in that a groove is formed on the ora terminalis at the hatch position that is suitable for cooperating rotating mechanism or on the sideboard of cargo hatch, guarantees that like this sealing of the hatch cover of closing is enough to resist inclement weather.

Another most preferred embodiment of the present invention is characterised in that the actuating device of rotating mechanism is suitable for sealing the outward flange of coaming, further to prevent injury and the easier close maintenance owing to handling goods was caused.

Below, the present invention is by being verified most preferred embodiment more detailed description in conjunction with the accompanying drawings.Wherein:

Fig. 1 has shown the schematic side elevation of one four formula hatch covers under its closed condition;

Fig. 2 has shown a lateral plan as Fig. 1, and this moment is because first pair of hatch parts of effect of first actuator are stowed in an end of hatch with its vertical state closure;

Fig. 3 has shown a lateral plan as Fig. 1 and Fig. 2, and this moment is because rotating mechanism makes a pair of hatch parts of back pack up in vertical state under the effect of its actuator;

Fig. 4 shows along the part top view of the being seen hatch of the direction shown in the A-A line among Fig. 1 and its sideboard, thus rotating mechanism extremely actuator at length displayed; And

Fig. 5 demonstrates a cutaway view along the B-B line among Fig. 4.

Referring to Fig. 1, wherein shown a hatch cover under in off position, described hatch cover comprises that four

hatch parts

1,2,3 that are hinged together conciliate.Under closed condition as shown in Figure 1, when parts 1-4 was placed by the approximate horizontal state, hatch cover had been closed the opening of the whole hatch of cargo hold in common mode.Parts 1 are connected with one first actuator 6, and the other end of first actuator 6 links to each other with rigid support on the ship.In addition, the maneuvering device of hatch cover comprises a rotating mechanism 7 and an actuator 8 thereof that shows with shadow in the

drawings.Actuator

6 and 8 can be used hydraulic actuation.

Rotating mechanism is general to adopt the lever with length arm to carry out, and described lever is on the infall of its length arm is mounted aboard ship rigid support.One end of the actuator 8 of rotating mechanism 7 is connected on the galianconism of rotating mechanism, and the other end of actuator is connected on the rigid support of ship simultaneously.As shown in Figure 4, later-model rotating mechanism 7 is placed in the end on the vertical and horizontal of ship of coaming with different array modes with prior art, it is in the inboard of the coaming of cargo hold 5 at least in part, and the pivot of rotating mechanism 7 and actuator devices 8 are placed in the outside of coaming thus.Making the end that lifts the hatch parts of rotating mechanism 7 remain in the hatch under the hatch cover, is not that to be in the cargo hold 5 be exactly the inner space that is positioned at hatch-board rest.Among Fig. 4, the side of the edge of coaming ship by mark 10 expressions is by 9 expressions.The part of rotating mechanism 7 and actuator 8 is advantageously provided on the coaming of cargo hold 5.

Fig. 5 has shown one along the being seen scheme drawing of B-B line among Fig. 4.As shown in the figure, the edge guide 11 of parts 1 is a trapezoidal basically groove 12 that matches with rotating mechanism 7.Mark 13 expression coamings, parts 1 are partly placed on the coaming 13.Mark 14 be illustrated between arm and the hatch cover and between arm and the coaming must the auxiliary seal bar.Replacedly, groove can be produced on the coaming 13.

In roughly common mode when parts 1 are opened hatch cover.At the beginning, first actuator 6 makes the

parts

1 and 2 of hatch cover turn to position shown in Figure 2.Simultaneously,

parts

3 and 4 are also moved to the end near the hatch opening slidably, and parts 3 are on the rotating mechanism 7.Rotating mechanism 7 long-armed tops need have a wheel, and when rotating mechanism was rotated, wheel was as contacting with the back side of parts 3.Then, actuator 8 moves to upright state with parts 3, and the parts 4 that hingedly are connected thus on the former also will correspondingly have been dragged.The state of above-mentioned end as shown in Figure 3.

The closing chamber flap obviously occurs in when starting actuator 8 with opposite direction, and actuator at first makes

hatch parts

3 and 4 rotate and turns back to position shown in Figure 2 thus.Then actuator 6 makes

hatch parts

1 and 2 turn to the accumbency state, and the off position of hatch cover shown in Figure 1 thus is by so last acquisition.

For those of ordinary skill in the field, the present invention should only not only limit to the foregoing description, but can be changed in the scope of appended claim.Nature, many different locks and other machinery are used to the switching mechanism combined action with hatch cover, to realize such as the hatch parts are fixed on the open position that it erects.Above-mentioned scope and many other details are common technology, and be irrelevant with purpose of the present invention, thereby omitted from above-mentioned explanation and accompanying drawing.
