Abstract
The utility model provides an anti-explosion door with a synchronous opening and closing mechanism. The anti-explosion door comprises a door frame, a first door leaf, a second door leaf, an intermediate door post and hinges, wherein the door frame is equally divided into two parts by the intermediate door post. The anti-explosion door is characterized by also comprising at least one pair of gear set; the first door leaf and the second door leaf are hinged on the intermediate door post by the hinges; the gear set is a pair of gears meshed mutually, and is arranged on the intermediate door post; and the pair of gears meshed mutually is respectively connected with the side surfaces of the first door leaf and the second door leaf. The anti-explosion door has the advantages that the two door leaves can be synchronously opened and closed by the pair of gears, so that the damage of the mechanism on the door leaves due to non-uniform stress and generated speed difference of the two door leaves is prevented, and the safety and the reliability are improved. Therefore, according to the anti-explosion door, the time for emergency rescue and salvage can be shortened, personal casualties are reduced, and the loss caused by accidents is reduced.
Description
Technical field
The utility model belongs to the explosion proof door technical field, particularly relates to a kind of explosion proof door with synchronous switching mechanism of coalmine ventilation safety device ventilating shaft.
Background technology
The explosion proof door of existing coalmine ventilation safety device ventilating shaft is typically designed to two door leafs; When the door leaf of explosion proof door was irregular by shock wave or high pressure draught impact, two door leafs can not open and close synchronously, and the anglec of rotation of door leaf can be greater than design angle; Therefore; Cause two door leaf unbalance stress, and produce speed difference, cause some devices and mechanism on the door leaf to damage.Will make like this and can't in time recover under the coal mine to ventilate, and then can't exhale pernicious gases, let the personnel of speedily carrying out rescue work lose and speedily carry out rescue work relief in the time of the time, also seriously jeopardize underground work personnel's life security, enlarge the disaster consequence easily.
Summary of the invention
The purpose of the utility model is to overcome deficiency and the problem that prior art exists; Provide a kind of two door leafs of explosion proof door that can make to realize opening and closing synchronously; Avoid causing device and mechanism on the door leaf to damage, further improve the explosion proof door with synchronous switching mechanism of safety and reliability.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of explosion proof door with synchronous switching mechanism, comprise doorframe 1, first door leaf 2, second door leaf 3, with doorframe 1 be divided into two-part in the middle of door pillar 5 and hinge 6; It is characterized in that: also comprise at least one pair of gear train 4; Described first door leaf 2 and second door leaf 3 all are hinged on the middle door pillar 5 through hinge 6; Described gear train 4 is a pair of pitch wheel; Gear train 4 is installed on the middle door pillar 5, and a pair of pitch wheel is connected with the side of first door leaf 2 and second door leaf 3 respectively.
The utility model is compared the beneficial effect that is had with prior art:
Can realize the synchronous switching of two door leafs through a pair of gear, prevent like this to have improved safety and reliability because two door leafs cause the mechanism's damage on the door leaf because of unbalance stress and the speed difference that produces.Thereby the time of the relief of can speedily carrying out rescue work in advance reduces casualties, reduces the loss that accident causes.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation.
Fig. 1 is the structural representation of the utility model.
Among the figure: doorframe 1, the first door leaf 2, the second door leafs 3, the door pillar 5 in the middle of the gear train 4, doorframe, hinge 6.
The specific embodiment
As shown in Figure 1, a kind of explosion proof door with synchronous switching mechanism, comprise doorframe 1, first door leaf 2, second door leaf 3, with doorframe 1 be divided into two-part in the middle of door pillar 5 and hinge 6; It is characterized in that: also comprise at least one pair of gear train 4; Described first door leaf 2 and second door leaf 3 all are hinged on the middle door pillar 5 through hinge 6; Described gear train 4 is a pair of pitch wheel; Gear train 4 is installed on the middle door pillar 5, and a pair of pitch wheel is connected with the side of first door leaf 2 and second door leaf 3 respectively.
The course of work of the utility model is:
Under coal mine, explosion time takes place, first door leaf 2 and second door leaf 3 are impacted by impact generated by explosion ripple and high pressure draught, owing to be provided with gear train 4 between first door leaf 2 and second door leaf 3; The door leaf 2 of winning is opened with identical opening angle with second door leaf 3; When impact generated by explosion ripple and high pressure draught in the past after, first door leaf 2 and second door leaf 3 are resetted, reseting procedure gear train 4 makes first door leaf 2 and the identical opening angle of second door leaf, 3 maintenances equally; After first door leaf 2 and second door leaf 3 reset and accomplish; Explosion proof door can be realized the sealing of well head again, and at this moment main air blower is extracted the pernicious gas of down-hole out, guarantees underground work personnel's safety.
