Abstract
The utility model discloses a pressure-resistant linkage alarm air door which comprises a door frame, a door panel and a limiting mechanism as well as an automatic controller, wherein the door frame comprises an outer frame and an inner frame; the inner frame is arranged in the outer frame; a buffering part is arranged between the outer frame and the inner frame; the door panel is rotationally connected with the inner frame; a locking air cylinder is mounted on the inner frame; one magnetic control sensor is mounted in corresponding positions of the door panel respectively; a voice alarm is further mounted above the outer frame; and the locking air cylinder, the magnetic control sensors and the voice alarm are all electrically connected with the automatic controller. The air door is controlled to be opened by the automatic controller, so that the automation degree is improved greatly, a rope is not required to be hung in a roadway, the roadway is clean, and the safety and the reliability are improved greatly.
Description
Technical field
The utility model relates to a kind of air door, particularly the chain alarm air door of a kind of resistance to compression.
Background technology
In the prior art, the air door that down-hole is used comprises doorframe, door-plate and position-limit mechanism, door-plate is flexibly connected with doorframe, on doorframe, be designed with position-limit mechanism end of door plate and carry out spacing its reverse flip that prevents, door-plate under normal circumstances under the effect of blast in closed condition.The circulation of gas when preventing that air door from opening, air door is all designed to twice, and twice air door should not opened simultaneously, between the twice air door of prior art, adopt wire rope interlocking, together with one air door is outer with two by wire rope, air door is connected, after one air door opened, another road air door is controlled and is lockable by wire rope, the interlocking air door of this form makes to have increased rope in tunnel and hangs, neat and artistic not, and interlocking air door safety, reliability is also poor, and the as easy as rolling off a log breaking-up of existing air door, ventilation equipment is built repeatedly, not only cause the waste of recruitment and material, also impact is produced and safety.
Utility model content
The purpose of this utility model is just to provide a kind of outward appearance succinct, the resistance to compression Interlocked alarming air door that safety and reliability is strong.
To achieve these goals, the technical solution adopted in the utility model is such: the chain alarm air door of resistance to compression of the present utility model, comprise doorframe, door-plate and position-limit mechanism, also comprise automatic controller, described doorframe is comprised of housing and inside casing, inside casing is arranged in housing, and be provided with buffer part between housing and inside casing, described door-plate and inside casing are rotationally connected, locking cylinder is installed on inside casing, on door-plate, opposite position is separately installed with a magnetoresistive sensor, phonetic alarm is also installed above housing, locking cylinder, magnetoresistive sensor and phonetic alarm are all electrically connected to automatic controller.
As preferably, housing is fixed in wall by anchor pole.
Compared with prior art, the utility model has the advantage of: doorframe of the present utility model comprises housing and inside casing, between inside casing and shell, use buffer, make housing at the laggard row buffering of the pressure that is subject to roadway deformation, inner frame structure is unaffected, air door also can normally be opened, air door is controlled and is opened by automatic controller, and automaticity improves greatly, in tunnel, without rope, hangs, make tunnel clean and tidy, and safety and reliability all improve greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, the chain alarm air door of resistance to compression of the present utility model, comprise doorframe, door-plate 1 and position-limit mechanism, also comprise automatic controller, described doorframe is comprised of housing 2 and inside casing 3, inside casing 3 is arranged in housing 2, and be provided with buffer part 4 between housing 2 and inside casing 3, described door-plate 1 is rotationally connected with inside casing 3, locking cylinder 6 is installed on inside casing 3, on door-plate 1, opposite position is separately installed with a magnetoresistive sensor 7, phonetic alarm 8 is also installed above housing 2, locking cylinder 6, magnetoresistive sensor 7 and phonetic alarm 8 are all electrically connected to automatic controller, housing 2 is fixed in wall by anchor pole 5.
Doorframe comprises housing 2 and inside casing 3, between inside casing 3 and shell, use buffer, make housing 2 at the laggard row buffering of the pressure that is subject to roadway deformation, inside casing 3 structures are unaffected, air door also can normally be opened, housing 2 is fixed in wall by anchor pole 5, increased the shock proof ability of doorframe, during use, after opening one air door, magnetoresistive sensor 7 on air door senses that signal transmission are to automatic controller, automatic controller is controlled phonetic alarm 8 alarm air doors and is opened, control locking cylinder 6 unlatchings of another road air door pins air door simultaneously, its phonetic alarm 8 prompting the place ahead air doors are opened simultaneously, after air door is closed completely, phonetic alarm 8 stop alarms, the locking of another road air door is removed simultaneously.
