Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is elaborated.
The basic composition of a kind of hatch cover locking device of the present utility model comprises that one runs through the rotating shaft of hatch cover, a set of shaft sealer, two rotation hand wheels, push and pull system and supporting pull nut.
Running through rotating shaft 1 is a metal shaft that runs through hatch cover 2, is respectively handwheel joint 1-1, sealing conical surface 1-2, twice O type ring recess 1-3, circlip groove 1-4, motion thread 1-5, keyway 1-6 and binding thread 1-7 out of my cabin from top to bottom.For preventing electrochemical corrosion, through-shaft adopts the metallic material with the identical material of hatch cover, and does antirust processing.
Shaft sealer comprise one with the axle sleeve 3 of hatch cover weld together, taper type nylon ring 4 and two O RunddichtringOs 5, for ensureing to there is sufficient intensity under the state of deep-sea, axle sleeve has larger thickness, inner hole of shaft sleeve top is taper, be under taper nylon ring mated condition can with the sealing conical surface that the runs through rotating shaft guarantee watertight of effectively fitting, simultaneously, O RunddichtringO can be effectively in the time being fixed in the O type ring recess that runs through rotating shaft and the laminating of axle sleeve inside face ensure sealing, inner hole of shaft sleeve column part top and lower diameter with run through rotating shaft relevant position diameter identical with confidential letter and allow to run through rotating shaft rotate, inner hole of shaft sleeve middle part cylindrical section between twice O RunddichtringO arranges the major diameter interval of certain length, reduce cylinder binding face length, on the basis of not losing water tightness, be convenient to install and rotating shaft rotation.
Handwheel 7 in handwheel 6, installation cabin, bottom is installed out of my cabin on rotating shaft top, and in cabin, handwheel centre hole arranges keyway, is installed on and runs through rotating shaft keyway position, can be driven and be run through rotating shaft rotation by handwheel in rotatable cabin.Handwheel exposes the square joint of handwheel out of my cabin 1-out of my cabin with through-shaft top out of my cabin) be connected, can ensure that cannot in the time of the drawback lock of cabin, run through rotating shaft from rotation out of my cabin completes unlocking action.
Connecting bar locking mechanism comprises three groups of push and pull system altogether, and angle 120 is spent mutually, ensures the reliability of blocking.In pull nut 8, there is motion thread, coordinate with the motion thread that runs through rotating shaft, can phase countershaft up-and-down movement in the time running through rotating shaft rotation.Pull nut has three three lug 8-1 that distribute with 120 degree angles, can be connected with short distractor bar 10 by pin 9-1.Three lug 3-1 that axle sleeve 3 outer rings also have three 120 degree angles to distribute, are connected with long draw bar 11 by pin 9-2.Long draw bar is connected with securing rod 12 rear ends by pin 9-3 with short distractor bar.Also be provided with three lug 2-1 in the corresponding angle of hatch cover Upper shaft sleeve lug position, be connected with steady arm 13 by pin 9-4, steady arm is connected with the position of close locking rod end front end by pin 9-5 again.Securing rod front end is slightly thinner than rear end, to adapt to completing of lock out action, removable soft pad 12-1 is set above securing rod front end, prevents that the pressure of lock-out state from producing destruction to securing rod main body or hatch fence 14.
The hatch fence 14 corresponding with this lockout mechanism requires bottom surface to have a plane, carrying out certain resistance to abrasion processing with securing rod front end contacting points position, as pasted nylon cushion etc.Hatch fence and withstand voltage spherical shell weld together, ensure bulk strength.
Initial condition, pull nut 8 is positioned at and runs through rotating shaft 1 motion thread bottom, fits with handwheel in cabin 7.After hatch cover 2 is closed, submersible chaufeur rotates counterclockwise handwheel in cabin, and pull nut is upward movement under the effect that runs through rotating shaft upper driving screw thread, and short distractor bar 10 clockwise rotates, long draw bar 11 rotates counterclockwise, link two lever pin nail 9-3 and outwards move, promote securing rod 12 and protract, simultaneously, because long draw bar rotates counterclockwise to approaching vertical state, make pin 9-3 produce downward motion, press down securing rod rear end, securing rod front end is provoked.In the time that securing rod protracts action, steady arm 13 rotates counterclockwise, further securing rod is upwards mentioned, under four bars act on simultaneously, securing rod completes protracting and front end vertical motion by a relatively large margin, make the replaceable soft pad of securing rod front end and the contact action of hatch fence 14 and produce certain pressure, under the leverage of spending at three groups of angles 120 acts on, completing the lock out action of hatch cover simultaneously.In the time that hatch cover has locked, the pulling force that pull nut keeps down to running through rotating shaft, the conical surface and the axle sleeve top conical surface that guarantee runs through rotating shaft compress nylon ring 4, ensure watertight state, and the twice o type circle that simultaneously runs through the setting of rotating shaft cylindrical section has further ensured the reliability of watertight.
In the time that release is moved, submersible chaufeur clockwise rotates handwheel in cabin, pull nut moves downward, short distractor bar 10 rotates counterclockwise, and long draw bar 11 clockwise rotates, and steady arm 13 clockwise rotates, securing rod completes front end and declines and backward movement, securing rod front end and hatch fence depart from and are reduced to and be less than hatch cover external diameter, and release has been moved, and hatch cover is able to smooth opening.
Break down in submersible inside while causing chaufeur to complete from inside rotating in cabin that handwheel completes hatch cover release action, the outer rescue group of submersible out of my cabin handwheel 6 is contained in and runs through roller end handwheel joint 1-1 position out of my cabin, and rotatable cabin outer hand wheel completes release and moves.
