Fig. 1 is the door leaf structure schematic diagram that in prior art, plank is put together;

The structural representation that Fig. 2 is combined type air door embodiment of the present invention;

The sectional view that Fig. 3 is door leaf in Fig. 2;

The motion principle figure that Fig. 4 is linkage in Fig. 2;

The structural representation that Fig. 5 is con-rod only in linkage.

The specific embodiment

The structural representation that Fig. 2 is combined type air door embodiment of the present invention; The sectional view that Fig. 3 is door leaf in Fig. 2; The present embodiment provides a kind of combined type air door, please refer to Fig. 2 and Fig. 3, comprising: doorframe 2, be arranged at two door leafs of splitting 3 in doorframe 2, and the linkage 4 for driving two door leafs 3 to open in the opposite direction respectively; Door leaf 3 comprises two plank layers 31 and is folded in two Anti-air-leakage interlayers 32 between plank layer 31, and plank layer 31 is fixedly connected with and is integral with Anti-air-leakage interlayer 32.

Particularly, doorframe 2 can be rectangle, the arch that also can be surrounded by the back timber of two columns 201 that vertically extend and arc, and doorframe 2 can fixedly be embedded passing through on mouth at the tunnel pier.Door leaf 3 can be symmetrically arranged two, and two door leafs 3 can seal up the spaces in doorframe 2 while cutting out fully; For example, when doorframe 2 is rectangle, door leaf 3 can be also rectangle, and the rectangle amalgamation of two door leafs 3 just forms the rectangle of doorframe 2 correspondences.

Door leaf 3 can be hinged on two columns 201 by the first hinge 301 and the second hinge 302 respectively, so that door leaf 3 can rotate to realize opening or closing of air door relative to column 201; And can be provided with linkage 4 between two door leafs 3, with the gearing by linkage 4 realize at a door leaf 3 towards first direction A direction (inwardly) while opening, another door leaf 3 towards second direction B(outwardly) open.

The both side surface of door leaf 3 can be can be for the Anti-air-leakage interlayer 32 of the materials such as plastic sheet or polyester formation, by Anti-air-leakage interlayer 32, more effectively to intercept wind circulation between 31, two plank layer 31 of plank layer identical with the door leaf shape.Preferably, the thickness of plank layer 31 can be 25mm, and Anti-air-leakage interlayer 32 can be comprised of at least two layer coated cloths.Wherein, between plank layer 31 and Anti-air-leakage interlayer 32, can be integral by being adhesively fixed.

Alternatively, plank layer 31 can be spliced to form by a plurality of parallel minute plates 311, under because of ore deposit pressure effect, causing roadway deformation, while causing doorframe 2 torsional deformation, can divide plate 311 and the shape of repairing easily plank layer 31 and door leaf by pruning, make the door leaf doorway 2 of adaptive deformation again; Maintenance is got up more convenient, also, without again building new air door by laying bricks or stones, has avoided causing the waste of manpower, financial resources, material resources.Anti-air-leakage interlayer Anti-air-leakage interlayer

The combined type air door that the present embodiment provides, can effectively prevent and leak out by the Anti-air-leakage interlayer is set, and lightweight, and door leaf opens and closes and is easy to control, and can be applicable to the large scale tunnel and use.

Preferably, two plank layers 31 also are fixedly connected with and are integral by bolt 34 with Anti-air-leakage interlayer 32.For example, on the outer surface of each plank side layer 31, a plurality of pressing plates 33 can be set, and the pressing plate 33 on door leaf 3 both side surface is oppositely arranged, 34, bolt is fixedly connected with two plank layers 31 to be integral with Anti-air-leakage interlayer 32 through two pressing plates 33 that are oppositely arranged.This bolted mode, can be changed easily to the Anti-air-leakage interlayer of its inside, improved application life and the maintainability performance of this combined type air door.

Further, linkage 4 comprise the first linking arm 41, the second linking arm 42 and be hinged on the first linking arm 41 and the second linking arm 42 between connecting rod 43, the end that the first linking arm 41 deviates from connecting rod 43 is fixedly connected on a door leaf 3, and an end that deviates from connecting rod 43 of the second linking arm 42 is fixedly connected on another door leaf 3.Wherein, the first linking arm 41 and the second linking arm 42 can be all L-shaped, be wherein in the bottom of " L " shape can be to connect base, this connection base can be welded and fixed the surface of door leaf 3.

The motion principle figure that Fig. 4 is linkage in Fig. 2; The opening procedure of linked-type air door the present embodiment provided below in conjunction with Fig. 4 describes.

As shown in Figure 4, the first linking arm 41 1 ends and connecting rod 43 is hinged, the other end and door leaf 3 are fixed into one, door leaf 3 is hinged on doorframe by the first hinge 301 again; Similarly, the second linking arm 42 1 ends and connecting rod 43 is hinged, the other end and door leaf 3 are fixed into one, door leaf 3 is hinged on doorframe by the second hinge 302 again; Thus, just form a four-bar mechanism, wherein the hinge at the first hinge 301, the second hinge 301 and connecting rod 43 two ends is four pin joints of this four-bar mechanism; When promoting the door leaf 3 hinged with the first hinge 301 and rotate to open this door leaf 3 towards the direction of first direction A in figure, the first 41 of linking arms are towards the second linking arm 42 place one side oscillations, connecting rod 43 is towards the second linking arm 42 1 side shiftings, and then drive the second linking arm 42 along second direction B rotation in figure, the door leaf 3 that drives this side is opened towards the second direction B contrary with first direction A, thereby has realized the coordinated type unlatching of two fan door leafs 3.The present embodiment, by the linkage that adopts connecting rod and connecting wall to form, has been realized the reverse open function of linked-type air door easily, simple in structure, operability good, improved the functional performance of air door.

Further, connecting rod 43 also can comprise con-rod only 430 and be bolted in the end bar 431 at con-rod only two ends, and the outer end of two end bars 431 is can be respectively hinged by the first connecting pin and the second connecting pin and the first linking arm and the second linking arm.Here, can offer pin-and-hole on the first linking arm 41 of end bar 431 and correspondence or the second linking arm 42, the first connecting pin can run through pin-and-hole on end bar 431 and the first linking arm 41 and both are hinged, and the pin-and-hole that the second connecting pin can run through on end bar 431 and the second linking arm 41 is hinged by both; Perhaps, only hold on bar 431 and be formed with pin-and-hole, the first connecting pin can be fixedly installed on the first linking arm 41, and the second connecting pin is fixedly installed on the second linking arm 42, and the first linking arm 41 and the second linking arm 42 are arranged in respectively pin-and-hole on corresponding end bar 41 to realize that both is hinged.

The combined type air door that the present embodiment provides, realizing the reverse unlatching of two door leafs, and can close easily, met the demand of passing through of main equipment, and have and utilize the weight alleviate each door leaf, the application life of improving air door.

Finally it should be noted that: above each embodiment, only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to aforementioned each embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: its technical scheme that still can put down in writing aforementioned each embodiment is modified, or some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of various embodiments of the present invention technical scheme.
