Description
Technical field
The utility model is related to a kind of drop shaft safety stop more particularly to a kind of section drop shaft safety stops.
Background technology
Drop shaft is vertical or inclined pit shaft of the connection two or several stages as rolling ore-rock, and existing inclined seam is opened
Mostly during adopting is that after connecting main chute by multiple section drop shafts, ore drawing is carried out by main chute, since ore/coal whereabouts generation is big
Dust is measured, dust can float from section drop shaft well head into tunnel, then float into operation area, endanger workers ' health, existing drop shaft dedusting
Mostly it is that ventilation blower is installed on main chute, makes to form negative pressure in drop shaft, reduces dust and generate, but since section drop shaft is in the presence of more
A, i.e., for drop shaft ventilating system there are multiple openings, ventilation effect is limited, and dust can still be spread into tunnel.
Utility model content
The purpose of this utility model is that proposing a kind of section drop shaft safety stop, drop shaft coal breakage is reduced by the way that spray tube is arranged
Shi Fenchen is generated, and by the way that vent flap and draft fan is arranged, the air feed into drop shaft mouth, being used cooperatively with main chute ventilation blower can be big
It is big to reduce coal dust diffusion in drop shaft, improve section dash environment.
The utility model includes safety stop, hinged on one side, the safety of the section drop shaft mouth of safety stop side corresponding thereto
Another side-line of shelves has traction rope, the traction rope other end to be connect with the electric hoist for being fixed on tunnel top, and the safety stop includes logical
Windshield plate, frame-type holder, spray tube, draft fan, the vent flap bottom fix frame-type holder, ventilation are fixed in frame-type holder
Spray tube is arranged in fan, frame-type frame bottom.
Electric hoist controls the folding of safety stop and section drop shaft mouth by traction rope, and when slipping coal, safety stop is opened, and coal cinder is made
It is slipped certainly to section drop shaft by transportation roadway, and then enters main chute, after slipping coal, safety stop is closed.Section drop shaft and main chute
Connection, draft fan air feed into section drop shaft, coordinate main chute in ventilation blower formed negative pressure, reduce drop shaft coal breakage when coal dust to
Diffusion in section road, while spray tube is set, to diffusing to the coal dust water spray dust in section drop shaft.
Described, vent flap is grid steel plate.
Ensure the air inlet of draft fan using grid steel plate, while safety stop being made to have enough intensity, prevents pedestrian from falling
To drop shaft.
Described, it is fixedly connected with blinds shape protective cover on the outside of draft fan.
Described, multiple atomizing spray holes are arranged in spray bottom of the tube.
The utility model has the beneficial effects that：
(1) section drop shaft safety stop described in the utility model, is provided with spray tube, to diffusing to the coal in section drop shaft
Powder water spray dust；
(2) section drop shaft safety stop described in the utility model, is provided with vent flap and draft fan, and draft fan is to section
Air feed in drop shaft coordinates the ventilation blower in main chute to form negative pressure, diffusion of the coal dust into section road when reducing drop shaft coal breakage,
Vent flap prevents pedestrian from dropping in drop shaft.
Description of the drawings
Fig. 1 is a kind of example structure schematic diagram；
Fig. 2 is a kind of embodiment using state structure diagram；
In figure：1, section drop shaft mouth；2, traction rope；3, electric hoist；4, vent flap；5, frame-type holder；6, spray tube；7,
Draft fan；8, blinds shape protective cover.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, section drop shaft safety stop described in the utility model, including safety stop, safety stop side and its
Corresponding section drop shaft mouth 1 it is hinged on one side, another side-line of safety stop has a traction rope 2,2 other end of traction rope and is fixed on lane
The electric hoist 3 on road top connects, and the safety stop includes vent flap 4, frame-type holder 5, spray tube 6, draft fan 7, described logical
Frame-type holder 5 is fixed in 4 bottom of windshield plate, and draft fan 7 is fixed in frame-type holder 5, and spray tube 6 is arranged in 5 bottom of frame-type holder；Its
In, vent flap 4 is grid steel plate, and 7 outside of draft fan is fixedly connected with blinds shape protective cover 8, and the setting of 6 bottom of spray tube is multiple
Atomizing spray hole.
Electric hoist 3 controls the folding of safety stop and section drop shaft mouth 1 by traction rope 2, and when slipping coal, safety stop is towed rope
2 tractions are opened, and so that coal cinder is slipped certainly to section drop shaft by transportation roadway, and then enter main chute, and after slipping coal, safety stop is closed.
Section drop shaft is connected to main chute, the air feed into section drop shaft of draft fan 7, is coordinated the ventilation blower in main chute to form negative pressure, is subtracted
Diffusion of the coal dust into section road when few drop shaft coal breakage, while spray tube 6 is set, to diffusing to the pulverized coal injection in section drop shaft
Water depositing dust ensures that draft fan 7 is entered the wind well using grid steel plate, while safety stop being made to have enough intensity, prevents pedestrian from falling
It drops down onto in drop shaft.
The utility model use process is as follows described：When inclined seam working face mining slips coal, safety stop is towed rope
Traction is opened, and coal cinder is slipped to section drop shaft certainly by transportation roadway, and then enters main chute；It slips coal to terminate, when main chute ore drawing, close
Safety stop opens draft fan and spray tube, draft fan is made to be slipped to section to section drop shaft confession wind, while by atomizing spray mouth
Well head water spray dedusting.
Certainly, the above is only the preferred embodiment of the utility model, be should not be construed as limiting new to this practicality
The scope of embodiments of type.The utility model is also not limited to the example above, and those skilled in the art are in this reality
With all the changes and improvements etc. made in novel essential scope, the patent covering scope of the utility model should all be belonged to
It is interior.
