Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is the structural representation of the utility model bracing or strutting arrangement.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Referring to Fig. 1～Fig. 3, the utility model embodiment comprises locking device and two parts of bracing or strutting arrangement that are arranged on door leaf cantilever end bottom.
Locking device comprises hook 1, travel switch 2, latch 3, nut 4, latch holder 5, hydraulic cylinder holder 6, hydraulic cylinder 7, pin base 8.Hook 1, latch holder 5, hydraulic cylinder holder 6 are arranged on protective door door leaf 18 back sides.Latch 3 is movably arranged on latch holder 5, and can move up and down at holder 5 axis.While being fixed on door leaf 18 full open with the pin base 8 of pin hole, on the ground of latch 3 belows, latch 3 can insert and depart from pin hole, and 8 pairs of latches 3 of pin base play position-limiting action.Hydraulic cylinder 7 is arranged on hydraulic cylinder holder 6, and the piston rod of hydraulic cylinder 7 is connected by nut 4 with latch 3.Travel switch 2 is arranged on the position of latch 3 upper and lower actions, and the effect of travel switch 2 is to detect latch 3 action situations and latch hand, electronic position.
During locking device work, pressure oil inlet hydraulic cylinder 7 rodless cavities, promote piston rod, by piston rod, drive upwards action of latch 3, and latch 3 is separated with the pin hole of pin base 8, realizes and removes latch.Pressure oil inlet hydraulic cylinder 7 rod chambers, promote piston rod, by piston rod, drive latch 3 to move downwards, and latch 3 inserts in the pin hole of pin base 8, realizes dead bolt 3.Travel switch 2 detects the position of removing latch 3 or dead bolt 3.Manually remove latch locking: turn on nut 4, then latch 3 horizontal rotaries are turn 90 degrees backward and mentioned, latch 3 is fixed on hook 1.When door leaf 18 is when keeping full open position, dead bolt device, guarantees now fixing of door leaf 18; When door leaf 18 device that first unlocks during at closing process, guarantee that door leaf 18 cuts out smoothly.
Bracing or strutting arrangement comprises supporting seat, wheel 11, axle 12, inclined board 13, declined board 14, bolt 15, base 16 and screw rod 17.Supporting seat comprises upper support seat 9, lower support seat 10.Upper support seat 9 is weldingly fixed on door leaf 18, and lower support seat 10 is bolted on upper support seat 9.Wheel 11 is movably arranged on lower support seat 10 by axle 12.When base 16 is fixed on door leaf 18 full open on the ground of wheel 11 belows.Wheel 11 coordinates with inclined board 13 tops.Inclined board 13 is arranged in base 16 up and downly, and inclined board 13 can move up and down in base 16.Inclined board 13 bottoms have ramp 19.Bolt 15 is arranged on base 16, and bolt 15 coordinates with inclined board 13, and 15 pairs of inclined boards 13 of bolt play locking effect.Declined board 14 left and right are arranged in base 16 actively, and declined board 14 can move left and right in base 16.Declined board 14 is threaded with screw rod 17.Declined board 14 tops have lower inclined plane 20, and ramp 19 contacts with lower inclined plane 20.Inclined board 13 tops are provided with slope 21.
Unclamp bolt 15, bolt 15 is separated with inclined board 13; By rotating adjusting screw(rod) 17, by screw thread gearing, make declined board 14 in base 16, to move left and right position, when declined board 14 moves left and right, by the annexation of ramp 19 and lower inclined plane 20, inclined board 13 can move up and down in base 16, to guarantee producing suitable support force after inclined board 13 contacts with wheel 11, makes door leaf 18 stressed evenly.After supporting well, twist inward bolt 15, bolt 15 holds out against skewback 13, makes skewback 13 lockings.
After opening the door and putting in place, the wheel 11 in bracing or strutting arrangement can be rolled on inclined board 13 tops, thereby door leaf cantilever end is played a supporting role, and slope 21 makes wheel 11 more easily be rolled into inclined board 13 tops.Latch 3 in locking device, under the driving of hydraulic cylinder 7, is inserted in the pin hole of pin base 8, thereby flood and preventive door is locked simultaneously, prevents flood and preventive door misoperation.
In addition, it should be noted that, the specific embodiment described in this manual, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this manual is only to the explanation of the utility model structure example.
