Abstract
The utility model discloses a non-pressure air door locking device. The non-pressure air door locking device is characterized in that a spring repositor is respectively mounted on two non-pressure air doors; each spring repositor adopts the structure that a lock case fixed on an air door leaf, a lock catch fixed on an air door frame and a pin in the lock case are included, and a spring is mounted in the lock case and is propped against a convex ring of the pin; and the two pins are tensioned through a wire rope, so that the pins are separated from the lock catches when the two air doors are closed at the same time. By adopting the non-pressure air door locking device, the problem that the two non-pressure air doors are opened at the same time is avoided, the air leakage is reduced, and the stability of the ventilation system of a mine is ensured.
Description
Technical field
The utility model relates to the air door in the underworkings of colliery.
Background technology
Applied non-pressure damper at the main air entering and returning connection roadway of mine at present.This air door is that steel welding forms, it has broken the form of structure of old-fashioned for a long time conventional wooden air door, cleverly the blast that acts on the air door is converted into a kind of internal force by balanced controls, it is balanced, fully demonstrate the structure uniqueness of this air door, outstanding advantage such as simple and practical, safe and reliable.Though non-pressure damper has solved the problem of installing reverse throttle, but wherein one non-pressure damper reaches 45 when spending, and another road non-pressure damper also reaches 45 degree simultaneously, can't realize the locking of non-pressure damper, can only realize chain, cause be opened to simultaneously 45 the degree phenomenons more.Because non-pressure damper is mainly built in air entering and returning lane, down-hole and the main air entering and returning connection roadway, to leak out greatlyyer so cause, the ventilation system instability does not meet in " safety regulations in coal mine " requirement yet.
Summary of the invention
In order to solve the deficiency of above-mentioned technology, the utility model provides a kind of non-pressure damper blocking device.
For achieving the above object, non-pressure damper blocking device of the present utility model is according to the principle of spring reset, a spring reset device respectively is installed on the twice non-pressure damper, the structure of spring reset device is: it comprises the lock housing that is fixed on the air door fan and the snap close and the interior pin of lock housing that are fixed on the air door, spring is installed in the lock housing, spring withstands on the bulge loop of pin, with the pin tension of wire rope, make pin be in disengaging snap close state under the closed condition simultaneously then at the twice air door with two spring reset devices.
Behind one door opening, wire rope loses pulling force, and the spring reset device latch resilience of another road non-pressure damper sticks in this road non-pressure damper can't open, and vice versa, thereby has realized the full engagement locking of non-pressure damper.Stop the problem that the twice non-pressure damper is opened simultaneously, reduced and leaked out, guaranteed the stable of mine ventilation system.This facility simple structure, advantage easy for installation, workable has effectively improved mine non-pressure damper reliability.

The specific embodiment
As shown in Figure 1, non-pressure damper blocking device of the present utility model is that a spring reset device respectively is installed on the twice non-pressure damper, the structure of spring reset device is: comprise the lock housing 3 that is fixed on the air door fan and be fixed on snap close 5 on the air door and the pin 2 in the lock housing 3, spring 4 is installed in the lock housing 3, spring 4 withstands on the bulge loop of pin 2, with wire rope 1 two pins 2 are strained then, made pin 2 be in disengaging snap close state under the closed condition simultaneously at the twice air door.
