Description
Technical field
The utility model relates to a kind of air door self-locking gear, particularly coal mine lower wind door self-locking gear, belongs to the plant equipment field.
Background technology
Air door should be established in the place that in mine ventilation system, should cut off distinguished and admirable pedestrian again or be open to traffic.Mining underground air door does not allow both sides to open simultaneously; But in the actual production activity; Particularly the pedestrian is open to traffic on the more frequent main tunnel, all someone's situation of opening air door of both sides occur through regular meeting, and air door is opened; Will close air door after the people enters, equally often the someone can forget the situation of closing air door at once.Cause leaking out of down-hole, string wind is prone to potential safety hazard.
Summary of the invention
The utility model provides a kind of air door self-locking gear, and this device can be realized not opening simultaneously of air door, and can realize closing automatically, has avoided the down-hole to leak out, and string wind guarantees to keep the safety in production and carries out.
Technical solution: the utility model comprises: first air door, and second air door is characterized in that; Be equipped with fixed head between first air door and second air door, fixed head is positioned near the axle of the air door side wall, and fixed head is provided with symmetrically arranged first counterweight and second counterweight; First counterweight and the second counterweight both sides are respectively equipped with limit shaft; First counterweight and second counterweight can limit shaft moves up and down on fixed head along both sides respectively, and the upper center between first counterweight and second counterweight is provided with fixed axis, and fixed axis is provided with right-angle baffle; Right-angle baffle can be swung on fixed axis; Right-angle baffle two right-angle sides lay respectively at first counterweight and second counterweight top, and the first counterweight top is connected with wire rope one end, and the wire rope other end is fixedly connected with first air door outside through fixed pulley; The second counterweight top is connected with wire rope one end, and the wire rope other end is fixedly connected through the fixed pulley and second air door are inboard.Fixed pulley is fixed on the axle of the air door side wall, and is highly suitable.A fixed pulley is positioned at one of them air door outside, and all the other fixed pulleys are all between two air doors.
The beneficial effect of the utility model is to open realization air door automatic closing function when can stop air door fully.Simple in structure, economical and practical, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
See Fig. 1, first air door 1 and second air door 2 are two common air doors, are equipped with fixed head 8 between first air door 1 and second air door 2; Fixed head 8 is positioned near the axle of the air door side wall; Fixed head 8 is provided with that symmetrically arranged first counterweight 3 and second counterweight, 4, the first counterweights 3 and second counterweight, 4 both sides are respectively equipped with limit shaft 5, the first counterweights 3 and second counterweight 4 can move up and down on fixed head 8 along both sides limit shaft 5 respectively; Upper center between first counterweight 3 and second counterweight 4 is provided with fixed axis 6; Fixed axis 6 is provided with right-angle baffle 7, and right-angle baffle 7 can be swung on fixed axis 6, and 7 liang of right-angle sides of right-angle baffle lay respectively at first counterweight 3 and second counterweight, 4 tops; First counterweight, 3 tops are connected with wire rope 9 one ends; Wire rope 9 other ends are fixedly connected with first air door, 1 outside through fixed pulley 11, and second counterweight, 4 tops are connected with wire rope 10 1 ends, and wire rope 10 other ends are through fixed pulley 11 and second air door, 2 inboard fixed connections; Fixed pulley 11 is fixed on the axle of the air door side wall, and is highly suitable.One of them fixed pulley 11 is positioned at wherein first air door, 1 outside, and all the other fixed pulleys 11 are all between between first air door 1 and second air door 2.
The course of work: the coal mine lower wind door must be against the wind to unlatching, and as shown in the figure, black tip direction is the down-hole wind direction.When opening first air door 1, necessary inverted air current direction is drawn back first air door 1 to the right; Wire rope 9 also moves right, and drives first counterweight 3 and rises, and first counterweight 3 rises and withstands right-angle baffle 7 right sides; Make right-angle baffle 7 left sides push down second counterweight 4, will be when opposite side get into as the people, must the inverted air current direction; When pushing 2 entering of second air door to the right open, wire rope 10 drives second counterweight 4 and rises to left movement; And this moment, second counterweight 4 was pushed down by right-angle baffle 7 left sides, can not rise, and second air door 2 can not be opened.After the people opened 1 entering of first air door, first counterweight 3 drove wire rope 9 to left movement because self gravitation decline resets, and wire rope 9 drives first air door 1 and shuts.Vice versa.
