Description
Technical field
This practicality relates to a kind of Antiexplosive manhole cover, is specifically related to a kind of automatically reset Antiexplosive manhole cover.
Background technology
At present, Antiexplosive manhole cover as protection mine ventilation system can not or few device, ensureing that the effect that mine ventilation system is run is more and more outstanding.Antiexplosive manhole cover is as one of the fixture of ventilation fan, and its Main Function has the following aspects: when mine ventilation is normal, ensures tightness, prevents ventilation short circuit; When gas explosion or coal-dust explosion occur in down-hole, under the effect of shock wave, Antiexplosive manhole cover can open release instantaneously, ensures that chief ventilators is from destruction; After gas or coal-dust explosion, Antiexplosive manhole cover can reset in time, ensures that mine ventilation system is normally run; When back lass, Antiexplosive manhole cover can be held on ventilating shaft collar set, avoids Air escape branch.
Tradition Antiexplosive manhole cover also exists serious design defect, mainly contains the following aspects.
Antiexplosive manhole cover in the on-state, can not automatic accurately reset, and because the iron block on weight is overweight, need manually to load and unload, operating procedure is more loaded down with trivial details.
Time blasting in down-hole, due to the unpredictability of shock wave energy, Antiexplosive manhole cover is very likely blown up, and affects the normal operation of mine ventilation system.
Summary of the invention
The utility model is intended to solve the problem, and provides one and to automatically reset Antiexplosive manhole cover, which overcome traditional Antiexplosive manhole cover can not fast, the drawback of parking position accuracy.
The utility model solves the technical scheme that its technical problem adopts: one automatically resets Antiexplosive manhole cover adjusting device, comprise Antiexplosive manhole cover, well lid TRAJECTORY CONTROL bar, energising magnet contactor, spring, energising magnet, common magnet, draught line, balance weight, presser feet and sealed liquid cell, described common magnet is arranged on Antiexplosive manhole cover, and described energising magnet and spring fitting are on well lid TRAJECTORY CONTROL bar.
Further, described spring is greater than the gravity of described balance weight by the elastic force after compressing and Antiexplosive manhole cover self gravitation.
The novel tool of this reality has the following advantages: Antiexplosive manhole cover in the on state, can fast, parking position accuracy, rational in infrastructure easy to operate, safe and reliable.
Accompanying drawing explanation
Fig. 1: the plane structure schematic diagram of a kind of automatically reset Antiexplosive manhole cover adjusting device of the utility model.
In figure: 1. Antiexplosive manhole cover, be 2. energized magnet contactor, 3. well lid TRAJECTORY CONTROL bar, 4. spring, and be 5. energized magnet, 6. draught line, 7. balance weight, 8. presser feet, 9. common magnet, 10. sealed liquid cell, 11. wind caves.
Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
As shown in Figure 1, the utility model one automatically resets Antiexplosive manhole cover adjusting device, comprise Antiexplosive manhole cover (1), energising magnet contactor (2), well lid TRAJECTORY CONTROL bar (3), spring (4), energising magnet (5), draught line (6), balance weight (7), presser feet (8), common magnet (9), sealed liquid cell (10), wind cave (11), described ordinary magnet (9) is fixed on Antiexplosive manhole cover (1), described well lid TRAJECTORY CONTROL bar (3) is through Antiexplosive manhole cover (1), described spring (4) and energising magnet (5) are fixed on well lid TRAJECTORY CONTROL bar (3), described spring (4) is greater than the gravity of described balance weight (7) by the elastic force after compressing and Antiexplosive manhole cover (1) self gravitation.
The utility model is when Antiexplosive manhole cover maintenance is normally ventilated, and control the pulling force of pull rope (6) according to the gravity of Antiexplosive manhole cover (1) and the quality of DH negative pressure size adjustment balance weight, such Antiexplosive manhole cover (1) just can cover at vertical ventilating shaft mouth, when ventilation fan is because of fault or when there is gas explosion, Antiexplosive manhole cover pulls Antiexplosive manhole cover (1) to move up along the direction of well lid TRAJECTORY CONTROL bar (3) under the effect of balance weight (7), pressure release is carried out to the shock wave in mine, protection chief ventilators is from destruction, after Antiexplosive manhole cover arrives certain location, touch energising magnet contactor (2), energising magnet (5) and common magnet (9) attract each other, accelerate Antiexplosive manhole cover (1) to move upward rapidly, to down-hole shock wave quick pressure releasing, Compress Spring (4) while that Antiexplosive manhole cover (1) being in the process moved upward, when chief ventilators recovers to ventilate, deenergization, energising magnet (5) loses magnetism, and Antiexplosive manhole cover (1) along well lid TRAJECTORY CONTROL bar (3) sharp downward movement, thus ensure that Antiexplosive manhole cover (1) resets quickly and accurately under the elastic force of self gravitation and spring (4).
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model manual and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (2)
1. the mining Antiexplosive manhole cover adjusting device that automatically resets, it is characterized in that: comprise Antiexplosive manhole cover (1), energising magnet contactor (2), well lid TRAJECTORY CONTROL bar (3), spring (4), energising magnet (5), draught line (6), balance weight (7), presser feet (8), common magnet (9), sealed liquid cell (10), wind cave (11), described ordinary magnet (9) is fixed on Antiexplosive manhole cover (1), described well lid TRAJECTORY CONTROL bar (3) is through Antiexplosive manhole cover (1), described spring (4) and energising magnet (5) are fixed on well lid TRAJECTORY CONTROL bar (3).
