Abstract

The utility model relates to an angular travel control rotary automatic ventilation door. The angular travel control rotary automatic ventilation door comprises a door leaf which is vertically arranged above a track in a tunnel, wherein a vertical rotary shaft is arranged in the middle of the door leaf; the top of the rotary shaft is connected with a rotating shaft of an angular travel controller through a fixer; the angular travel controller and the fixer are respectively fixed with a wall on the upper part of the tunnel; and a pair of limiting locking devices is arranged on the two sides of the tunnel and positioned on the front and back surfaces of the door leaf. The angular travel control rotary automatic ventilation door has an automatic opening/closing function, so an underground ventilation door is automatically controlled. According to the ventilation door, the defect that the door leaf is easy to deform to cause air leakage when a common ventilation door is used at a high-air-pressure place is overcome, the ventilation door can also serve as a reverse ventilation door to realize bidirectional air separation, the safety and reliability of the ventilation door are improved, the problems of inconvenience in people walking, vehicle running and manual closing of the ventilation door are solved, a phenomenon that a person is hurt by the ventilation door is effectively prevented, the labor intensity of an operator is reduced, the production rate is improved, and the safety production is ensured.

Description

The rotational automatic air door of angle Stroke Control

Technical field

The utility model relates to a kind of mine laneway air door, and Stroke Control rotational automatic air door in especially a kind of angle belongs to mine ventilation control field.

Background technology

Air door is one of distinguished and admirable key facility of down-hole control, and the intact and normal use of air door is directly connected to the unimpeded of down-hole ventilation safety and transportation, and the air door that use in most of at present transportation lane is impact type; The air door that use on the sidewalk is artificial push-to-open type, and this type air door is closed the door by the inclination weight of self mostly, because the quality and the closed imprecision of air door; Add the imperfection of management work, will cause a large amount of leaking out, and vehicle running collision formula air door; Member is fragile; Need often maintenance, and artificial push-to-open type air door safety factor is less, and the accident of hindering the pedestrian takes place to squeeze often.

The utility model content

In order to address the above problem, the utility model provides the rotational automatic air door of a kind of angle Stroke Control, this air door has the automatic open and close function; Make underground air door realize automation control, and this air door has been when having changed common air door and using in the big place of blast, door leaf is easy to generate the shortcoming that distortion is leaked out; But the double as reverse throttle is realized two-way separated wind, has improved its safety and reliability, has solved problems such as pedestrian, driving, air door manual control switch inconvenience; Effectively prevented the hurt sb.'s feelings generation of incident of air door; Alleviated working strength of workers, improved productivity ratio, ensured safety in production.

The utility model solves the technical scheme that its technical problem adopted: the rotational automatic air door of this angle Stroke Control comprises angle journey controller, fixator, axis of rotation, door leaf and limited position stoppage device; Said self closing door has a door leaf that vertically is installed on inner orbit top, tunnel; The centre of said door leaf is equipped with vertical axis of rotation; The top of said axis of rotation is connected with the rotating shaft of angle journey controller through fixator, and angle journey controller and fixator are fixed with the body of wall on top, tunnel respectively; The positive and negative that the both sides in said tunnel are positioned at door leaf is equipped with a pair of limited position stoppage device, and making door leaf be merely able to one-directional rotation, that air door is closed is tight, prevents to leak out.

The beneficial effect of the utility model is: the rotational automatic air door of this angle Stroke Control has the automatic open and close function, makes underground air door realize automation control, and this air door is when having changed common air door and using in the big place of blast; Door leaf is easy to generate the shortcoming that distortion is leaked out; But the double as reverse throttle is realized two-way separated wind, has improved its safety and reliability, has solved problems such as pedestrian, driving and air door manual control switch inconvenience; Effectively prevented the hurt sb.'s feelings generation of incident of air door; Alleviated working strength of workers, improved productivity ratio, ensured safety in production.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Accompanying drawing 1 is the structural representation of the rotational automatic air door of this angle Stroke Control.

Accompanying drawing 2 is the rotational automatic air door closure state of this an angle Stroke Control vertical view.

Accompanying drawing 3 is the rotational automatic air door open mode of this an angle Stroke Control vertical view.

Among the figure, 1. angle journey controller, 2. fixator, 3. axis of rotation, 4. door leaf, 5. limited position stoppage device, 6. body of wall, 7. tunnel, 8. track.

The specific embodiment

In the accompanying drawings, the rotational automatic air door of this angle Stroke Control comprises angle journey controller 1, fixator 2, axis of rotation 3, door leaf 4 and limited position stoppage device 5; Said self closing door has a door leaf 4 that vertically is installed on 7 inner orbits, 8 tops, tunnel; The centre of said door leaf 4 is equipped with vertical axis of rotation 3; The top of said axis of rotation 3 is connected with the rotating shaft of angle journey controller 1 through fixator 2, and angle journey controller 1 is fixing with the body of wall 6 on 7 tops, tunnel respectively with fixator 2; The positive and negative that the both sides in said tunnel 7 are positioned at door leaf 4 is equipped with a pair of limited position stoppage device 5, and making door leaf 4 be merely able to one-directional rotation, that air door is closed is tight, prevents to leak out.

Said angle journey controller 1 adopts power-equipment commonly used as power source.

Said angle journey controller 1 is controlled door leaf 4 and is realized-90 degree rotations of 0 degree, and when vehicle passed through, air door was received enabling signal; It is parallel with track 8 that journey controller 1 driven rotary axle 3 in angle is opened air door; Angle journey controller 1 stops operating, and vehicle is passed through smoothly, after vehicle is gone over; Angle journey controller 1 begins counter-rotating closes air door, reaches the purpose at a distance from wind.

The rotational automatic air door of this angle Stroke Control is more suitable for being applied in the double track haulage roadway, and said track 8 is made as and comes and goes two, and limited position stoppage device 5 is installed in respectively on the body of wall 6 with near the track 8 traffic direction opposition sides of one of which side; When dynamical system goes wrong; During like power failure or blowing-out, then can vehicle be passed through smoothly, if it is on the scene not have the staff through this air door of opened manually; The Vehicular impact air door applies the unlatching that normal stress is realized air door to door leaf 4, and vehicle is passed through smoothly.

Stroke Control rotational automatic air door in said angle both can be set to turn clockwise according to the traffic direction of track 8, can be set to again be rotated counterclockwise, and the also corresponding change in installation site of limited position stoppage device 5 simultaneously guarantees that the rotation of door leaf 4 is not interrupted.
