Specific embodiment
For further illustrating that the present invention is to reach technological means and effect that predetermined goal of the invention is taken, below in conjunction with
Accompanying drawing and preferred embodiment, to the specific embodiment of the door according to moon pool bottom proposed by the present invention, structure, feature and
Its effect, after describing in detail such as.
As depicted in figs. 1 and 2, a kind of door of moon pool bottom of the present invention is a kind of, including two door body 1, master cylinder 2,
Main crank 3, latch 4, plugging pin oil cylinder 5, latch operating crank 6 and side rod mechanism 7.
Described two door body 1 are symmetrical arranged, the latch 4 of fixing door body 1 when being provided with closure two door body joints, and lead to
Cross a plugging pin oil cylinder 5 to drive.
As shown in Figures 4 and 5, the both ends in each door body 1 fixing end are arranged with two master cylinders 2 respectively, and often
Individual master cylinder 2 is connected with door body 1 by main crank 3, and master cylinder 2 can rotate around main crank 3, and described master cylinder 2 and latch are oily
Cylinder 5 is all installed in sky cabin 10.
Each main crank 3 described is provided with a rotating shaft 31 and fixing axle 32, and described rotating shaft 31 is connected with master cylinder 2 axle, separately
Fixing axle 32 is connected with door body 1, and described fixing axle 32 is arranged with sealing device 33 and axle sleeve 34 successively.
As shown in Fig. 9, Figure 10 and Figure 11, described latch operating crank 6 is provided with two rotating shafts, one of rotating shaft 61 with insert
Pin oil cylinder 5 is connected, and another rotating shaft 62 is connected with a linkage 7, and described linkage 7 is connected with door body 1 by latch 4.
Described linkage 7 is made up of 71, two connecting rods 72 of rotating disk, the first crank axle 73, the second crank axle 74, described turn
Disk 71 is connected with the rotating shaft 62 of latch operating crank 6, and each connecting rod 72 one end described is all connected with rotating disk 71 inside groove, and two companies
