Description
Technical field
The utility model relates to a kind of adjusting device, especially a kind of mine anti-explosion well lid adjusting device, belongs to safety of coal mines protection and mine ventilation system adjustment field.
Background technology
At present, all collieries up to standard are all provided with Antiexplosive manhole cover.In coal mining, complete ventilation system is the prerequisite of safety of coal mines exploitation, the normal operational support of the chief ventilators supply of down-hole fresh air.Antiexplosive manhole cover is as one of the main fixture of ventilation fan, and its Main Function has the following aspects: when mine normally ventilates, and Antiexplosive manhole cover can keep tightness, avoids Air escape branch; When down-hole is once generation gas or coal-dust explosion, by the percussion of down-hole high pressure blast, Antiexplosive manhole cover can open pressure release instantaneously to protect chief ventilators from destruction; After mine generation gas or coal-dust explosion, Antiexplosive manhole cover can reset in time, recovers ventilation system integrality; Chief ventilators accidental power failure or there was a mechanical failure etc. reason shuts down time, Antiexplosive manhole cover can be opened automatically, utilizes the ventilation that natural ventilation pressure keeps mine certain; When implementing back lass, Antiexplosive manhole cover can be held on ventilating shaft collar set, avoids being caused Air escape branch by blast jack-up.
Tradition Antiexplosive manhole cover there is serious design defect, primarily of the following aspects.
Antiexplosive manhole cover in the on-state, can not Rapid reset, the quality of counter-balanced heavy hammer is slightly larger than the quality of Antiexplosive manhole cover, need manually the quality of the quality of the weight of counter-balanced heavy hammer slightly larger than counter-balanced heavy hammer during reset, the weight of the weight in counter-balanced heavy hammer is the iron block of unified processing and fabricating, quality is large, without handle, remove and unload inconvenience, removes required time when unloading longer.
Antiexplosive manhole cover in the on-state, can not parking position accuracy, because the counterweight iron block on weight needs manually to remove one by one to unload, removing Antiexplosive manhole cover unbalance stress in the process of unloading, be difficult to the quality ensureing Antiexplosive manhole cover, need during reset manually the weight in counter-balanced heavy hammer to be moved, make the quality of Antiexplosive manhole cover be greater than the quality of counter-balanced heavy hammer.
The impact force that well shooting produces can not be predicted, if there is serious explosion accident in down-hole, produce strong shock wave Antiexplosive manhole cover to be blown up, after down-hole blasts, a large amount of oxygen participates in blast, and the oxygen content of underground air sharply declines, and is badly in need of fresh air, keep normal ventilation, the extension just very likely caused the accident.
Utility model content
The utility model is intended to solve the problem, and provides a kind of mine anti-explosion well lid adjusting device, 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: a kind of mine anti-explosion well lid adjusting device, comprise counterweight support, pulley, rope, balancing weight, spring, tension, adjustable ring rotating handles, Antiexplosive manhole cover, adjustable ring, sealed liquid cell is protruding, described pulley is arranged on counterweight support, described rope is walked around pulley one end and is connected with Antiexplosive manhole cover, the other end is connected with balancing weight, described spring upper end and balancing weight weld together, lower end and adjustable ring weld together, described tension is processed with the draw-in groove that a row is highly different, described adjustable ring is welded with the projection that can match with tension draw-in groove.
Described adjustable ring is welded with four projections, be positioned in the draw-in groove of four tensions respectively, rotating adjustment ring, protruding draw-in groove position in tension can be regulated, described tension has four, spaced 90 degree of four orientation being positioned over Antiexplosive manhole cover.
The utility model tool 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.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
As Figure 1-5, a kind of mine anti-explosion well lid of the utility model adjusting device, comprise counterweight support (1), pulley (2), rope (3), balancing weight (4), spring (5), tension (6), adjustable ring rotating handles (7), Antiexplosive manhole cover (8), adjustable ring (9), sealed liquid cell (10), protruding (11), described pulley (2) is arranged on counterweight support (1), described rope (3) is walked around pulley (2) one end and is connected with Antiexplosive manhole cover (8), the other end is connected with balancing weight (4), described spring (5) upper end and balancing weight (4) weld together, lower end and adjustable ring (9) weld together, described tension (6) is processed with the highly different draw-in groove of a row, described adjustable ring (9) is welded with the projection (11) that can match with tension (6) draw-in groove, described adjustable ring (9) is welded with four projections (11), be positioned in the draw-in groove of four tensions (6) respectively, by rotating adjustment ring (9), the position of projection (11) in tension (6) draw-in groove can be regulated, with the elastic force of regulating spring (5), thus regulate the pulling force size needed for Antiexplosive manhole cover (8), described tension (6) has four, spaced 90 degree of four orientation being positioned over Antiexplosive manhole cover (8).
The utility model is when Antiexplosive manhole cover maintenance is normally ventilated, projection (11) on adjustable ring (9) is stuck in the draw-in groove on tension (6), the elastic force of spring (5) and the weight sum of counterweight are less than weight and Antiexplosive manhole cover (8) the inside and outside atmospheric pressure difference sum of Antiexplosive manhole cover (8), and such Antiexplosive manhole cover (8) just can cover on vertical ventilating shaft mouth.When blast for some reason by blowing-out or down-hole for ventilation fan, Antiexplosive manhole cover (8) rises by Antiexplosive manhole cover (8) under the acting in conjunction of counterweight and spring (5) pulling force, ventilates or protection ventilation fan temporarily to utilize natural ventilation pressure.By the time after ventilation fan recovers ventilation, Antiexplosive manhole cover (8) is needed again to cover quickly and accurately on returnairshaft, now to rotate an adjustable ring rotating handles (7), make four projections (11) on tension (6) screw out draw-in groove on tension (6) simultaneously, four springs (5) lost its bounce simultaneously, avoid unbalance stress when Antiexplosive manhole cover (8) falls after rise, ensure that parking position accuracy.After spring (5) lost its bounce, the deadweight of Antiexplosive manhole cover (8) is greater than the weight of counterweight, and Antiexplosive manhole cover (8) is just automatic accurate resets to vertical ventilating shaft mouth, thus ensure that Antiexplosive manhole cover (8) resets quickly and accurately.After ventilation is stable, then rotating adjustment ring (9), make in the draw-in groove of projection (11) precession tension (6), Antiexplosive manhole cover (8) just continues to remain normal and ventilates.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
