Abstract
A vertically pivoted falling type flood protection air-tight door comprises a doorframe, a door leaf, a worm gear interlock, a double hinge axis flap and an elevating mechanism. A hinged pull-push rod is provided at the top of the link of the worm gear interlock, said pull-push rod goes through the pull-push rod cover positioned longitudinally in the door leaf, the base plate crosses the door leaf and the top of the doorframe, one end is fixed on the upper part of the pull-push rod cover and the other end is fixed on a lock sleeve. The lock sleeve is corresponding to the lock hole of the upper lock base, the upper lock head goes through the lock sleeve. A pin shaft hinged lever is provided between the pull-push rod and the upper lock head, the center of the lever is hinged on the base via a central shaft, and the lower part of the base is fixed on the base plate. The door leaf can withstand impact load by the front and the water pressure for a depth of above 10m by the back. The door leaf can bear loads in two directions and adapt to a certain gradient range because there is no protruding doorsill on the ground. The door leaf opens flexibly, converts easily and translates reliably, and is suitable for flood protection works in subterranean tunnels.
Description
(1) technical field
The utility model belongs to and is used in that subterranean tunnel is anti-to be flooded and defend nuclear explosive shock wave, radioactivity toxic agent and gas to enter the airtight blast door that the door of a kind of specific use of preventive works inside, particularly access are used.
(2) background technology
Large span door in the existing preventive works adopts plug-type opening/shutting mode usually.Push-pull door adopts the side direction push-and-pull to open and close, and is provided with the ground groove of plate with cover, does not establish threshold, and being convenient to passes through with wartime at ordinary times uses.But after opening, need a special space of depositing, deposit door leaf, so civilwork engineering quantity is big, the cost height when if engineering oral area excavation space is restricted, more can't adopt.If adopt vertical rotary type to open and close door leaf, door leaf just must have lifting gear, when the door leaf lifting, be difficult for keeping opposing parallel between roomy door leaf and the doorframe, a plurality of tapered ends are difficult for entering simultaneously lockhole, locking tapered end on the door leaf and the locking lockhole on the doorframe easily produce dislocation, and the weather strip on the door leaf can not be subjected to even compression, and the sealing of door leaf and doorframe can not be satisfied the anti-needs that flood.Because the width size of access is bigger, the short transverse size is less relatively.The door leaf center of gravity is far away from hinge page or leaf shaft centre line, and the door leaf quality is bigger, and door leaf is opened, converting from wartime to peacetime production and vice versa is relatively required great effort.
(3) utility model content
The purpose of this utility model provides the anti-airtight blast door that floods of a kind of upright commentaries on classics landing-type, solution guarantees that the upright biparting anti-airtight blast door vertical lift that floods of landing-type that changes does not misplace, guarantees that a plurality of tapered ends enter lockhole simultaneously, evenly compress weather strip on the doorframe, solve anti-ly flood, protection, airtight technical problem; And the solution door leaf is opened the difficult problem that peace war conversion is required great effort.
The technical solution of the utility model: a kind of upright commentaries on classics landing-type is biparting to be prevented flooding airtight blast door, comprises doorframe, door leaf, worm and gear linkage lock, two hinge hinge page or leaf and elevating mechanism, is provided with adhesive tape groove and sponge rubber bar at the doorframe periphery, it is characterized in that:
The hinged pull bar in connecting rod top of worm and gear linkage lock, this pull bar runs in the guide to be indulged in the door leaf in the pull bar cover of putting, prop up seat board across door leaf and doorframe top, one end and pull bar cover top are fixed, other end center fixed lock tube, and lock tube is corresponding with the lockhole of last latch receptacles, last tapered end runs in the guide in the lock tube, by the bearing pin hinged lever, the middle part of lever is hinged on the bearing by axis between pull bar and last tapered end, and the bottom of bearing is fixed on the seat board.
On a seat board, connect the lock cover that covers lever and last tapered end.
Lockhole in last latch receptacles is built-in with force-bearing piece.
The utility model compared with prior art has following beneficial effect: owing to adopt double-leaf vertical-revolving formula scheme, do not need between bigger Tibetan door, so saved civil engineering costs widely.Ground does not have the threshold of protrusion, can overcome the influence of certain gradient, need not deposit a space, and the land used trench cover is paved runway at ordinary times, convenient driving.At ordinary times function of use with wartime function of use combine, converting from wartime to peacetime production and vice versa is quick.When using at ordinary times, door leaf is in opening, and is in raised position, after door leaf puts in place, can close locking, and ground is smooth not to have threshold.When wartime or need of work use, the trench cover plate is raised placement on one side.After the door leaf landing, close locking again, forward utilizes the locking ripple that withstands shocks to act on the shock wave active force that the door leaf transmission comes, and oppositely bears hydraulic action in the door leaf water pressure, rely on ground groove medial surface to become the supporting surface of door leaf, the while is as door leaf and doorframe lower seal limit.Worm and gear link gear, rapid operation are adopted in locking.By rotating the locking handwheel, the worm reducer drivening rod action in the locking, and then drive a plurality of locking heads and move up and down and implement to unblank and shut.This moment, linkage lock provided power and two effects of bearing load of crush seal adhesive tape.A plurality of tapered ends put in place in the process of closing the door simultaneously, have guaranteed the light, flexible, accurate of lock operation.
Two hinges cut with scissors the page or leaf light and flexible, bear the weight of door leaf, and the overturning moment of door leaf gives balance by two hinges hinge pages or leaves.Guarantee that in the door leaf opening-closing process, door leaf is parallel with the doorframe face, thereby the locking tapered end on the door leaf is aimed at the latch receptacles lockhole on the doorframe.When closing the door leaf locking, a plurality of tapered ends enter lockhole simultaneously, overcome the door leaf translation freedoms, make the even compressed sponge rubber strip of door leaf, and door leaf and doorframe fit tightly, and translation is airtight reliable.Sealing joint strip is that the integrally closed annular connects around the doorframe.The nuclear shockwave load can be born in this every fan front, and water depth pressure more than ten meters can be born in the back side, and door leaf is two-way distinguishes the bearing load effect, satisfy anti-ly flood, protection and airtight needs, be specially adapted to the anti-of underground river-crossing tunnel and flood and preventive works.
