The invention relates to a stairway hole hatch cover for a ship. The stairway hole hatch cover comprises a cover plate and an installing frame, and a pair of corresponding sides of the cover plate and the installing frame is hinged together. The stairway hole hatch cover is characterized in that a groove is arranged on an outer lateral side of the cover plate opposite to the hinged point, a linkage shaft is arranged in the groove, and thimbles are fixed at two ends of the linkage shaft and extend into the inside of the cover plate. A supporting plate is fixed inside the cover plate, through holes are arranged on the supporting plate and corresponding positions of a side of the cover plate corresponding to the supporting plate, spring bolts are arranged in the through holes, one ends of the spring bolts extend out of the cover plate, the other ends of the spring bolts extend into the through holes of the supporting plate, and lock latches corresponding to the spring bolts are arranged on the installing frame. Bosses are arranged on sections of the spring bolts inside the cover plate in circumferential direction, compression springs are arranged between the bosses and the supporting plate, and one sides of the bosses back on the supporting plate butt against the thimbles. A handle switch is fixed on the outer side the linkage shaft in the groove, and a handle is fixed on the inner side of the linkage shaft. By means of the hatch cover, opening and closing of the cover plate can be achieved fast, conveniently and flexibly, high-strength thick steel plates are not required, hatch cover weight can be reduced, and the weight of the ship is reduced.
Description
Technical field
The present invention relates to the hatchcover on a kind of naval vessel, is the deck on naval vessel, the hatchcover of the upper-turn-type that uses of companion-way road junction place up and down specifically.
Background technology
At present, on the deck of military boats and ships or ship for civil use, current mouthful of place of the ladder access between the cabin all needs to arrange hatchcover up and down, 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 the installing frame of hatchcover and cover plate each limit except hinged limit a plurality of snap closes to be set evenly, realize the switching of hatchcover by these snap closes, this mode adopts Multi-point locking at installing frame and cover plate, its opening-closing process need to operate 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 around the cover plate and the side in the installing frame lockhole corresponding with the locking bolt position arranged all, 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 the keying that this mode can a plurality of locking points of disposable realization, 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 is with regard to so that hatchcover has larger weight, thereby has increased the weight on naval vessel.
Summary of the invention
The problem to be solved in the present invention provides a kind of naval vessel with ladder access mouth hatchcover, adopts this hatchcover, can realize quick, light, flexibly the keying of cover plate, and need not to adopt 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 invention 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 the groove, be rotatable shape between universal driving shaft and groove and cooperate, 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 the through hole, and an end of dead bolt stretches out outside cover plate, and the other end stretches in the gripper shoe through hole, are fixed with snap close in the corresponding position in the dead bolt outside on the described installing frame.On that section dead bolt between cover plate side and gripper shoe circumferential boss is arranged, cover has Compress Spring on that section dead bolt between boss and gripper shoe, and a boss dorsad side of gripper shoe relies on described thimble.The outside that is positioned at that section universal driving shaft of cover plate groove is fixed with grip switches, the 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 at cover plate inboard from this through hole.
The further improvement of the present invention 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:
Because naval vessel of the present invention is that two dead bolts, two snap closes are set respectively on relative limit, the hinged limit of cover plate and installing frame with ladder access mouth hatchcover, and two dead bolts can open and close by grip switches or the disposable control of handle that is fixed on the 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 invention is to realize by dead bolt and snap close with cover plate and the locking between the installing frame of ladder access mouth hatchcover, and dead bolt and snap close itself just has higher intensity, therefore the manufacturing 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.
