Abstract
An anti-explosion air-tight door for a mine refuge chamber is provided with a door frame and a door leaf, wherein a fireproof sealing strip is embedded in a groove of the door leaf, hand wheels are arranged inside and outside the door leaf, the inside and outside hand wheels are simultaneously connected and fixed with a pinion through hand wheel shafts, the pinion is meshed with a gearwheel, the gearwheel is connected with one ends of a plurality of connection rods, the other ends of the connection rods are respectively connected with a plurality of locking handles, the locking handles are combined with wedge blocks on the door frame, each wedge block is provided with an inclined surface. The fireproof sealing strip is not damaged easily, the locking is more reliable and the air tightness is good.
Description
Technical field
The utility model relates to mine underground emergency avoiding device, be specifically related to the explosion-proof sealed door of a kind of mine refuge underground chamber, also can be used for the mine move the explosion-proof sealed door of survival capsule, boats and ships discharge water hatch door, the explosion-proof sealed door in bomb shelter etc. other to the exigent sealed door of tightness.
Background technology
At present, refuge chamber is burst accident such as gas or coal-dust explosion and fire, floods, roof fall to take place and distress personnel can't withdraw the time in the down-hole, mine, the existence confined space of a safety is provided for the survival personnel.When blast in the down-hole, refuge chamber is subjected to frontal impact, it is very big to be that the refuge chamber door bears the impact force of blast, weather strip is very easily destroyed under impacting, cause refuge chamber gas leakage, do not reach airtight requirement, an airtight space that waits for rescue is provided for underground operators when in danger.The refuge chamber door is being closed at ordinary times in addition, in order to avoid inside plant destroyed, but requires can open the refuge chamber door fast when disaster takes place, and the injury that disaster is brought drops to minimum.
Summary of the invention
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and provide a kind of mine refuge underground chamber explosion-proof sealed door, make refuge chamber air tight, tightness is good, and disaster can open the door when taking place fast, and the existence confined space of a safety is provided for distress personnel.
The technical solution adopted in the utility model is:
The explosion-proof sealed door of a kind of mine refuge underground chamber, have doorframe and door leaf, in the groove of door leaf, inlay the fire proof seal bar, handwheel is set inside and outside the door leaf, inside and outside handwheel is connected and fixed by hand wheel shaft and pinion simultaneously, pinion and gear wheel engagement, and gear wheel connects an end of many connecting rods, the other end of many connecting rods connects a plurality of locking handles respectively, the voussoir associating on locking handle and the doorframe.
In the technique scheme, described voussoir leaves an inclined-plane.
Compare with present technology, the utility model has the advantages that:
1. the fire proof seal bar is embedded in the door leaf, avoids being impacted when disaster takes place and produces destruction.
2. gear wheel links to each other with 4 groups of locking handles of four direction respectively by 4 connecting rods, has avoided the interference between the connecting rod, and each locking handle all is that self-movement makes that locking is more reliable.
3. locking handle cooperates with voussoir, has both guaranteed that locking handle can embed smoothly, can guarantee that again the fire proof seal bar has enough decrements, guarantees tightness.
Description of drawings
Fig. 1 is the utility model structural representation.
The accompanying drawing marking explanation:
The 1-doorframe, 2-fire proof seal bar, 3-voussoir, 4-connecting rod, 5-gear wheel, 6-handwheel, 7-pinion, 8-hand wheel shaft, 9-locking handle, 10-door leaf.
The specific embodiment
Referring to Fig. 1, the explosion-proof sealed door of mine refuge underground chamber of the present utility model is embedded in fire proof seal bar 2 in the groove of door leaf 10, avoids being impacted when disaster takes place and produces destruction.Handwheel 6 is set inside and outside the door leaf 10, inside and outside handwheel 6 is connected with pinion 7 by hand wheel shaft 8 simultaneously, pinion 7 and gear wheel 5 engagements, gear wheel 5 drives 9 motions of five pairs of locking handles simultaneously by connecting rod 4, thereby the fire proof seal bar on the door leaf 10 2 is produced uniform thrust, guarantee that fire proof seal bar 2 pressure are even, distortion is consistent, thereby guarantees its tightness.Locking handle 9 cooperates with voussoir 3 on the doorframe 1, and voussoir 3 leaves an inclined-plane, has both guaranteed that all locking handles 9 can embed smoothly, and can produce enough decrements after guaranteeing again to embed fire proof seal bar 2 is out of shape, thus the assurance tightness.
Claims (2)
1. explosion-proof sealed door of mine refuge underground chamber, it is characterized in that: have doorframe and door leaf, in the groove of door leaf, inlay the fire proof seal bar, handwheel is set inside and outside the door leaf, inside and outside handwheel is connected and fixed by hand wheel shaft and pinion simultaneously, pinion and gear wheel engagement, and gear wheel connects an end of many connecting rods, the other end of many connecting rods connects a plurality of locking handles respectively, the voussoir associating on locking handle and the doorframe.
2. the explosion-proof sealed door of mine refuge underground chamber according to claim 1 is characterized in that: described voussoir leaves an inclined-plane.
