Description
Technical field
The utility model relates to a kind of mine ventilation safety device, particularly a kind of positive and negative throttle setting.
Technical background
The positive and negative throttle setting of mine is to guarantee the stable a kind of requisite ventilation equipment of ventilation system in the mine.It comprises positive air door, inverted ventilation door, wind header case, is provided with positive air door push rod device in the wind header case, and wherein positive air door is provided with chute, and positive air door is slidingly connected by chute with push rod device one end and righteous style and practice door, and the other end and wind header case are hinged.During work, positive air door is realized the switching of positive air door under electronic, pneumatic or hydraulic-driven with push rod device.The unlatching of the positive air door of existing positive and negative throttle setting only relies on positive air door push rod device, is difficult to realize smoothly opening when the tunnel blast is big.Simultaneously, be used for the push rod device that positive air door opens and closes owing to only be provided with in the wind header case, positive and negative door leaf opens and closes separately.Wherein positive air door be used for the tunnel intercept distinguished and admirable, prevent the ventilation system short circuit, play the effect that guarantees that pedestrian and vehicle are normally current, be normally off.Inverted ventilation Men Ze is the door body that intercepts the unexpected reverse distinguished and admirable configuration that occurs in down-hole, is normally open.This positive and negative structure of operation respectively, maximum drawback is in daily ventilating management, reverse distinguished and admirable obstruct is not entered into a kind of normally off equally with the distinguished and admirable obstruct of forward, can't catastrophe occur, the very first time of realization inverted ventilation is closed the inverted ventilation door, increases ventilation safety hidden danger.
Summary of the invention
The utility model is in order to solve in the existing positive and negative throttle setting because blast is big, make open the door need be very big the manpower effect, and not reverse distinguished and admirable obstruct is set to normally off and the technical problem that exists, and a kind of positive and negative throttle setting is provided, and is used to reduce ventilation safety hidden danger.
The utility model is achieved through the following technical solutions:
Positive and negative throttle setting comprises positive air door, inverted ventilation door, wind header case, positive air door push rod device, also comprise positive air door release push rod device, positive air door is arranged in the wind header case with the release push rod device, and an end and wind header case are hinged, and the other end contacts with positive air door.When opening positive air door, positive air door plays the effect of release with push rod device, reduces the dynamic action that opens the door.
Further, positive and negative throttle setting also comprises inverted ventilation door push rod device and the inverted ventilation door release push rod device that is arranged in the wind header case, described inverted ventilation door is hinged with push rod device one end and wind header case, the other end contacts with the inverted ventilation door, described inverted ventilation door is hinged with release push rod device one end and wind header case, and the other end contacts with the inverted ventilation door.When opening the inverted ventilation door, the inverted ventilation door plays the effect of release with the release push rod device, can reduce the dynamic action that opens the door.The inverted ventilation door with push rod device and inverted ventilation door with release push rod device and positive air door with push rod device and positive air door with employing dynamic Control in parallel (being Synchronization Control) between the release push rod device, opening the door or elongation simultaneously or shortening at closing time like this, making positive and negative air door reach and opening and closing simultaneously is the technique effect of positive and negative air door interlock.
Described positive air door is fixed on the positive axle of the air door of spacing position farthest, air door top with the release push rod device, and described inverted ventilation door is fixed on spacing inverted ventilation door-hinge position farthest, air door top with the release push rod device.
Described inverted ventilation door is provided with chute, and the inverted ventilation door is hinged with push rod device one end and wind header case, and the other end and inverted ventilation door are slidingly connected by chute.
Described positive air door is hinged with the wind header case with the end branch of push rod device is two-layer up and down with push rod device and inverted ventilation door.
The utility model is simple in structure, easy for installation, and can be electronic in routine, pneumatic and the basis of the positive and negative air door that surges on transform or change, positive and negative door opens and closes smooth and easy and can realize the interlock of positive and negative air door, extensive use in the positive and negative air door reduces ventilation safety hidden danger greatly under existing coal mine.
