Description
Technical field
The utility model relates to the hatchcover on a kind of naval vessel, is the hatchcover of the upper-turn-type of the deck on naval vessel, the place's use of upper and lower companion-way road junction specifically.
Background technology
At present, the current mouthful of place of ladder access on the deck of military boats and ships or ship for civil use, between upper and lower cabin all needs to arrange hatchcover, and this hatchcover is the structure of upper-turn-type, and its Main Function is to keep the relative closure independence between warship cabin, reduces rain leakage.Traditional upper-turn-type hatchcover mainly contains two kinds of structures: a kind of is on each limit except hinged limit, a plurality of snap closes evenly to be set on the installing frame of hatchcover and cover plate, realize the switching of hatchcover by these snap closes, this mode adopts Multi-point locking on installing frame and cover plate, its opening-closing process need to be operated successively to each locking point, expends time in more; Another kind is that the center position at hatch cover arranges turning handle, and along four direction, a plurality of locking bolts are set respectively in cover plate inside, on side in the side of cover plate surrounding and installing frame, the lockhole corresponding with the locking bolt position all arranged, the rotation turning handle, controlled lockmaking bolt stretches out or retracts from the lockhole of cover plate and installing frame, thereby realize the switching of hatchcover, although this mode can disposablely realize the keying of a plurality of locking points, but the internal construction of its cover plate is comparatively complicated, and opening-closing process needs manpower rotation turning handle, and labor intensive is larger.In addition, because a plurality of locking points of above-mentioned these two kinds of structure hatchcovers all can be subject to effect of stress, therefore must use high-intensity thick steel plate processed just can avoid the distortion of installing frame or cover plate, this just makes hatchcover have larger weight, thereby has increased the weight on naval vessel.
The utility model content
Problem to be solved in the utility model is to provide ladder access mouth hatchcover for a kind of naval vessel, adopt this hatchcover, can realize quick, light, flexibly the keying of cover plate, and without adopting high-intensity thick steel plate processed, can reduce hatchcover weight, thereby alleviate the weight on naval vessel.
For solving such scheme, take following technical scheme:
Naval vessel of the present utility model comprises cover plate and installing frame with ladder access mouth hatchcover, and a pair of corresponding sides of cover plate and installing frame are hinged.Be characterized in fluted on the cover plate lateral surface of pin joint offside, universal driving shaft is arranged in groove, be rotatable shape between universal driving shaft and groove and coordinate, and the axis of universal driving shaft is parallel with the hinged limit of cover plate.The two ends of described universal driving shaft are all stretched in cover plate, and the universal driving shaft two ends all are fixed with thimble, and thimble all points to the cover plate inboard.At the universal driving shaft two ends with the hinged limit of cover plate between that section cover plate inside be fixed with the gripper shoe vertical with cover plate, and gripper shoe is parallel with the universal driving shaft axis.All there is through hole described gripper shoe and the cover plate side relevant position corresponding with it, and dead bolt is arranged in through hole, and an end of dead bolt stretches out outside cover plate, and the other end stretches in the gripper shoe through hole, on described installing frame, in the corresponding position in the dead bolt outside, are fixed with snap close.On that section dead bolt between cover plate side and gripper shoe, circumferential boss is arranged, on that section dead bolt between boss and gripper shoe, cover has a Compress Spring, boss dorsad a side of gripper shoe with together with described thimble relies on.The outside that is positioned at that section universal driving shaft of cover plate groove is fixed with grip switches, inboard is fixed with handle, and grip switches and handle all can be controlled universal driving shaft and rotate.The through hole that strip is arranged on cover plate corresponding to described groove, the direction of this through hole and handle to stir direction corresponding, described handle stretches out in the cover plate inboard from this through hole.
The further improvement of the utility model scheme is to be connected with air spring between the inboard and cover plate medial surface in the hinged limit of described installing frame, utilize the gas tension of inside of air spring can partly or entirely offset the deadweight of cover plate, thereby alleviate the manpower of cover plate required consumption in opening-closing process.
Take such scheme, have the following advantages:
Due to naval vessel of the present utility model, with ladder access mouth hatchcover, be, on the limit relative on the hinged limit of cover plate and installing frame, two dead bolts, two snap closes are set respectively, and two dead bolts can open and close by grip switches or the disposable control of handle be fixed on universal driving shaft, and only need use less strength to realize, so it opens and closes operation and has quick, light, characteristics flexibly.In addition, naval vessel of the present utility model is to realize by dead bolt and snap close with cover plate and the locking between installing frame of ladder access mouth hatchcover, and dead bolt and snap close itself just has higher intensity, therefore the manufacture of this hatchcover only need adopt high-intensity steel sheet to get final product, can greatly reduce the weight of hatchcover, thereby alleviate the weight on naval vessel.
