Detailed description of the invention
Below in conjunction with the accompanying drawings, provide preferred embodiment of the present utility model, and be described in detail.
Fig. 2 and Fig. 3 respectively illustrates according to novel ventilating shaft protective door of the present utility model in opening and closed mode.
This novel ventilating shaft protective door includes xoncrete structure 1, doorframe 2, door leaf 3, elevating mechanism 4 and blocking mechanism 5.Wherein, concrete
Structure 1 is positioned at the top on ground 20, and doorframe 2 is fixed on xoncrete structure 1, and door leaf 3 realizes rising under the effect of elevating mechanism 4
Fall motion, when in the closed position, at least part of door leaf 3 is placed in doorframe 2, and by means of blocking mechanism 5 by door
Fan 3 is locked in closed mode.
Fig. 4 is the enlarged drawing of the region A of Fig. 3, and the outside of doorframe 2 is fixedly connected on xoncrete structure 1 by anchoring piece 11,
Elevating mechanism 4 is connected to the inner side of doorframe 2.This elevating mechanism 4 includes guide holder 41 and screw rod 42, this fixing connection of guide holder 41
In the inner side of doorframe 2, screw rod 42 arranges and inserts this guide holder 41 screw-internal thread fit along lifting direction.
Fig. 5 is the upward view of Fig. 3, illustrated therein is elevating mechanism 4 and the blocking mechanism 5 of the bottom surface being arranged at door leaf 3.Its
In, elevating mechanism 4 includes lifting motor 43, lifting cross diverter 44 and two reducer of turbodrill 45, lifting motor 43 and liter
Fall cross diverter 44 is connected, and two reducer of turbodrill 45 are connected to lift the two of cross diverter 44 by drive link 46 respectively
Side, screw rod 42 is vertically installed on this reducer of turbodrill 45.Understanding in conjunction with Fig. 4, this elevating mechanism 4 includes being subtracted by four turbines
Speed device 45 is arranged on four screw rods 42 of the bottom surface of door leaf 3, and four guide holders 41 are fixed in the inner side of doorframe 2, and lifting motor 43 leads to
Crossing cross diverter drives screw rod 42 to rotate, so that door leaf 3 realizes lifting.Under peacetime state, by opening lifting electricity
Door leaf 3 can be increased to specified altitude assignment by machine 43, it is achieved the air-conditioning requirement of vertical shaft at ordinary times.
