It is rotating with planet carrier.The planet carrier side, which is distributed along the circumference with, to be locked along the locking level of planet carrier radial expansion
One end of fixed pole is hinged on ring gear, and the other end is connected by guiding mechanism with cover board.On the inside of the hatch fence circumferentially
It is evenly equipped with fore shaft, under hatch board closed state, the outer end position of fore shaft and the locking level corresponds.The locking device
Have central shaft, which passes through the sun gear and the two in being fixedly connected, the both ends of central shaft stretch out planet carrier it
Outside, the end face that central shaft corresponds to cover board one end has the blind hole of polygon, the other end of central shaft to be fixed with main handwheel.
Further improvement of the utility model scheme is that the guiding mechanism includes guide holder along cover board radial arrangement,
The outer end of guide holder all extends to side edge thereof and the two is in being fixedly connected, and the inner end of guide holder all extends to cover plate central and one
Body is connected on an axle sleeve, which is sleeved on the central shaft and the two is in be slidably matched.The guide holder is each attached to
Planet carrier periphery, planet carrier are in be fixedly connected with cover board by guide holder.The planet carrier corresponds on the outerplanar of cover board side
It is distributed along the circumference with axis pin, there is the through-hole along cover board radial arrangement on guide holder.The locking level includes connecting rod and locking bar, is connected
One end of bar is sleeved on the axis pin, and for the other end of connecting rod with locking bar in hinged cooperation, locking bar both passes through corresponding guide holder
Through-hole.
There are the annular convex platform of integrally connected, annular convex platform and planet carrier on that section of central shaft between the axle sleeve and planet carrier
Between that section of central shaft on be cased with compressed spring.There are locking slot, the master in the outer surface that the planet carrier corresponds to main handwheel side
There is self-lock pin on handwheel, when cover board is locked on hatch fence by locking device, the self-lock pin is located in locking slot.
Further improvement of the utility model scheme is that the blind hole of the polygon of the center axial end is regular hexagon.
The further improvement project of the utility model is that the sealing device is relief valve, and relief valve is from the outside to the core successively
For bonnet, thread segment and free-sliding spline section, bonnet is located on the outside of cover board and the outer diameter of bonnet is more than the internal diameter of cover central hole, spiral shell
Line section and cover central hole are in screw-thread fit, and free-sliding spline section is connected with assistant's wheel and the two is in sliding axially, circumferentially fixed match
It closes, assistant's wheel is in axial restraint, circumferentially rotates cooperation by wheel seat and cover board.There is cloth along longitudinal direction on the thread segment of the relief valve
The gas pressure relief slot set.
Said program is taken, is had the following advantages：
Due to the utility model can the locking device of hatch board of fast opening and closing include planet carrier, the axis of the planet carrier
Perpendicular and the two is in and is fixedly connected with cover board；Arranged concentric has ring gear in the planet carrier, have in ring gear sun gear and

In the lock answered so that cover board 2 is locked on hatch fence 1.Meanwhile the self-lock pin 21 on main handwheel 15 sinks to corresponding cover board
In the locking slot 20 of 2 locked positions, avoid collision or maloperation caused by cover board 2 be not closed completely or open.The normally-open cabin
Lid, as long as above-mentioned action reversed is operated.The relief valve being arranged in centre bore on cover board 2 can play all-balanced cover
The effect of inner and outer air pressure.Under normal condition, the thread segment 72 of relief valve should completely be screwed with the centre bore of cover board 2 so that be let out
Indent 74 is located in centre bore and 2 inside of cover board, and bonnet 71 is pressed on 2 outer surface of cover board, packing state is in cabin.Work as needs
Balance external and internal pressure and when carrying out pressure release, rotate bonnet 71 in 2 outside of cover board so that entire relief valve is screwed out to 2 outside of cover board,
One end of gas pressure relief slot 74 is exposed in 2 outside of cover board, and gas pressure relief slot 74 can be connected to the space inside and outside cover board 2 at this time, play pressure release
The effect of balance.
It, only need to be in the valve of 2 outside rotation relief valve of cover board when needing to open the hatch board from outside when there is operating mode of meeting an urgent need
Cap 71, and relief valve is taken out completely；It recycles die nut to stretch into the centre bore of cover board 2, and sinks to locking device central shaft
In 16 blind hole 19；Then die nut and central shaft 16 are pushed, the self-lock pin 21 of main handwheel 15 is made to be detached from planet carrier 18
Locking slot 20, so that it may with rotary middle spindle 16 so that the outer end of locking level is detached from the lock of hatch fence 1, easily by cover board 2
It opens.This damage operation, required driving force is small, easy to operate, efficient.Meanwhile the damage operation does not destroy hatch board
Any parts, after damage operation, only relief valve need to be reinstalled to 2 centre bore of cover board, can not only be repeated several times
It uses, and the quantity of crossing cabin part can be reduced, promote the integrally-built leakproofness of hatch board and stability.
