Abstract
The utility model discloses an automatic locking device of an air door for a mine. The automatic locking device of the air door for the mine is characterized in that door leaves positioned on the leeward sides of two air doors are both provided with automatic locking insertion pins with springs; the bottom frames of door frames are provided with corresponding locking insertion holes, and the top frames of the door frames are provided with fixed pulleys; the fixed pulleys are right above the automatic locking insertion pins; locking ropes bypass the two fixed pulleys to be connected with the two locking insertion pins and are enabled to just lift the two locking insertion pins to leave from the locking insertion holes when the two door leaves are both in closing states; and the windward sides of the two air doors are respectively provided with an automatic door closer. The automatic locking device disclosed by the utility model effectively prevents the two air doors from being simultaneously opened, eliminates the influence of human factors on the safety of mine ventilation and ensures the stability of a mine ventilation system, thereby ensuring the safety of the mine ventilation; and more importantly, the automatic locking device disclosed by the utility model provides a reliable and powerful guarantee for downhole safety.
Description
Technical field
The utility model is mine air door.
Background technology
Air door is the key facility of mine ventilation, and each air door point is generally established the twice air door, and the twice air door can not be opened simultaneously, if the twice air door is opened simultaneously, can cause Air escape branch, upsets the stability of mine ventilation, affects the safe ventilation of mine.But some worker may scheme conveniently to save trouble, and operates against regulations when mine car is crossed air door pushing away, and the twice air door is opened simultaneously, and mine car is directly passed through, and has so just caused Air escape branch, has upset the stability of mine ventilation, has affected the safe ventilation of mine.Although have on air door is installed the locking rope, though the twice air door can not all reach maximum, but can open simultaneously, mine ventilation safety can not get ensureing.
Summary of the invention
The purpose of this utility model is to prevent that the twice air door from opening simultaneously, eliminates human factor to the impact that mine ventilation safety causes, and designs a kind of mine air door self-locking gear.
The technical solution of the utility model is, a kind of mine air door self-locking gear, it is the automatic blocking latch that all is equipped with on the door leaf of the leeward side of twice air door with spring, the underframe of doorframe is provided with corresponding locking jack, the top frame of doorframe is provided with fixed pulley, and fixed pulley be in the locking latch directly over the position, the locking rope is walked around two fixed pulleys and is connected on two locking latches, and guaranteeing the twice door leaf simultaneously during closed condition, the locking rope is just in time mentioned twice locking latch and is left the locking jack; Windward side at the twice air door is respectively equipped with door check.
For the protection blocking rope, cover has the protection steel pipe on the locking rope.
The utility model has the advantages that: when normal, the twice air door is closed simultaneously, twice locking latch is mentioned and is left the locking jack, when opening wherein one air door, the locking rope will fluff along with the unlatching of air door, and another road air door locking latch will auto-extending, and this air door is pinned, after only having another road air door to close, could open again this road air door.So effectively having prevented the twice air door opens simultaneously, eliminated the impact that human factor causes mine ventilation safety, guaranteed the stability of mine ventilation system, guaranteed the safety of mine ventilation, the more important thing is to downhole safety provides reliable sound assurance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: the 1-fixed pulley, the 2-door leaf, 3-locking latch, 4-locking jack, the 5-door check, the 6-doorframe, 7-locking rope, 8-protects steel pipe.
The specific embodiment
As shown in Figure 1, a kind of mine air door self-locking gear, it is the automatic blocking latch 3 that all is equipped with on the door leaf 2 of the leeward side of twice air door with spring, the underframe of doorframe 6 is provided with corresponding locking jack 4, the top frame of doorframe 6 is provided with fixed pulley 1, and fixed pulley 1 be in locking latch 3 directly over the position, be connected on two locking latches 3 with a locking rope 7, and locking rope 7 is walked around two fixed pulleys 1, and guaranteeing twice door leaf 2 simultaneously during closed condition, locking rope 7 is just in time mentioned twice locking latch 3 and is left locking jack 4; Windward side at the twice air door is respectively equipped with door check 5.
For protection blocking rope 7, cover has protection steel pipe 8 on the locking rope.
Claims (2)
1. mine air door self-locking gear, it is characterized in that, it is the automatic blocking latch that all is equipped with on the door leaf of the leeward side of twice air door with spring, the underframe of doorframe is provided with corresponding locking jack, the top frame of doorframe is provided with fixed pulley, and fixed pulley be in the locking latch directly over the position, the locking rope is walked around two fixed pulleys and is connected on two locking latches, and guaranteeing the twice door leaf simultaneously during closed condition, the locking rope is just in time mentioned twice locking latch and is left the locking jack; Windward side at the twice air door is respectively equipped with door check.
