As shown in Fig. 5 to Fig. 8, the electronic side rolling hatch cover 200 of the present invention comprises two pieces of cover plates 210,220 be slidably installed on hatch body 300, and drive unit 230,240.Drive unit 230,240 is for driving the folding of two cover plates 210,220 herein.Especially, drive unit 230,240 comprises tooth bar 211,221, and it is separately positioned on cover plate 210,220 towards on the medial surface of hatch body 300, preferably be arranged on the medial surface center of cover plate 210,220, in cover plate 210,220 translation motion and driven wheel 232 engage.
Here drive unit 230 is consistent with the structure of drive unit 240, therefore easy in order to describe, and be only described in detail drive unit 230, those skilled in the art should be able to know the corresponding construction of drive unit 240.
As shown in Figure 7 and Figure 8, drive unit 230 also comprises sector gear 231 and driven wheel 232, wherein one end rotary type of sector gear 231 is fixed on hatch body 300, the other end is provided with gear and is positioned at the side of tooth bar 211, for engaging with driven wheel 232 when cover plate 210,220 heave.Preferably, one end of sector gear 231 is fixed on hatch body 300 by hinge 235.
Meanwhile, driven wheel 232 to be fixed on hatch body 300 and to be positioned at the opposite side of tooth bar 211.Further, tooth bar 211,221 is arranged on the center position of cover plate 210,220, makes tooth bar 211,221 in cover plate 210,220 translation motion and driven wheel 232 engages.
Further preferably, sector gear 231 is provided with the first push mechanism 233, and is also provided with guide peg 212 on the medial surface of cover plate 210 towards hatch body 300.Guide peg 212 is preferably perpendicular to tooth bar 211.Like this when cover plate 210 is in jacking state, the first push mechanism 233 offsets with guide peg 212, provides horizontal thrust to cover plate 210.
Especially, in order to can smoothly cover plate 210 jacking be got up, need the first push mechanism 233 to offset with guide peg 212 and form larger thrust.Therefore, lever principle is adopted between hinge 235, first push mechanism 233 and driven wheel 232 herein.As shown in Figure 7, distance between hinge 235 and driven wheel 232 is L1, distance between hinge 235 and the first push mechanism 233 is L2, and L1 is greater than L2, the amplification of power can be produced thus at the first push mechanism 233 place, namely driven wheel 232 drives the power needed less by motor, and the power that the first push mechanism 233 place produces is corresponding larger.
If the product of the thrust that the distance between the first push mechanism 233 and hinge 235 and the first push mechanism 233 produce is S1, the product of the driving force that the spacing of hinge 235 and driven wheel 232 and driven wheel 232 are subject to is S2, then S1 equals S2, namely meets lever principle.So just can realize by less driving force, produce larger thrust, effectively achieve the amplification of power, thus smoothly cover plate 210 jacking be got up.As can be seen here, when designing the position of the first push mechanism 233, preferably determine the distance between the first push mechanism 233 and hinge 235 according to the multiplication factor of actual required power.
Further, sector gear 231 is also provided with the second push mechanism 234, makes the second push mechanism 234 near the gear parts of sector gear 231.Like this when driven wheel 232 engages with the second from the bottom of sector gear 231 or the 3rd teeth portion, the second push mechanism 234 offsets with guide peg 212.When driven wheel 232 starts to engage with tooth bar 211, the second push mechanism 234 is thrown off with guide peg 212.First push mechanism 233 and the second push mechanism 234 all can select flat roller or cylinder, and wherein flat roller is stressed comparatively large, the better effects if of anti-vibration, and the cost of cylinder is lower.Both can play the effect that horizontal thrust is provided to cover plate.Like this under the driving of driven wheel 232, sector gear 231 provides horizontal thrust by the first push mechanism 233 for cover plate 210, realizes the heave movement of cover plate 210.
In like manner, under the driving of driven wheel 232, sector gear 231 for cover plate 210 provides horizontal thrust by the second push mechanism 234, is driven the tooth bar 211 of cover plate 210 center, realizes the translational motion of cover plate 210 in conjunction with driven wheel 232.
In addition, preferably the thickness of the second push mechanism is greater than the thickness of described first push mechanism, and the thickness of driven wheel is greater than the thickness of described tooth bar, and capable transmission can be made so more steady.
According to structure shown in Fig. 5 to Fig. 8, the original state of hatch board 200 is that cover plate 210,220 is completely closed, and driven wheel 232 now engages with sector gear 231, and the first push mechanism 233 is close to guide peg 212.When hatch board 200 opened by needs, whole drive unit provides power by motor (not shown) by driven wheel 232, driven wheel 232 drives sector gear 231 to rotate, under the horizontal thrust produced between the first push mechanism 233 and guide peg 212, realize the oblique heave of cover plate 210.
In like manner, realize the heave action of cover plate 220 simultaneously.Motor described here provides power source by the power system on ship by cable, and the control of motor also needs the various actions being realized drive unit by a set of control system.
Fig. 9 is that marine electric side rolling hatch cover of the present invention jacking is to the top view under translation state.Figure 10 is that marine electric side rolling hatch cover of the present invention jacking is to the lateral view under translation state.Figure 11 is the top view of marine electric side rolling hatch cover of the present invention jacking to the drive unit part under translation state.
As shown in Figures 9 to 11, when the cover plate 210,220 of hatch board 200 is opened to two ends, and when cover plate 210,220 completes heave action under the engagement rotation of driven wheel 232 and sector gear 231, cover plate 210,220 needs excessively to translation state.Now, the first push mechanism 233 is thrown off with guide peg 212, and the second push mechanism 234 offsets with guide peg 212.Under the horizontal thrust produced between the second push mechanism 234 and guide peg 212, driven wheel 232 and sector gear 231 continue engagement rotation.
When the end 2311 of sector gear 231 and the initiating terminal 2111 of tooth bar 211 overlapping time, driven wheel 232 transits to and the engaging of tooth bar 211 from engaging of sector gear 231, thus completes hatch board 200 by heave status transition to translation state.In whole process, the contact point of drive unit 230 and hatch board 200 has three: the first push mechanism 233, second push mechanism 234 and tooth bar 211 on sector gear 231.
