Description
Technical field
The utility model is related to mining production equipment technical field, and in particular to a kind of for mine down-hole excavation operation
Ventilation equipment.
Background technology
During mine down-hole excavation operation, due to having hit a large amount of debris and dust near driving face, cause to lead to
Wind is slower, and carbonomonoxide concentration is often higher.If operating personnel can not understand the carbon monoxide near driving face in time
, there is larger potential safety hazard in concentration, it may occur however that anthracemia.Meanwhile, it is used for being passed through fresh air in prior art
Negative pressure cloth air duct usually extend near driving face, easily crumbled by big gun.
Need badly in prior art a kind of can make operating personnel understand in time carbonomonoxide concentration near driving face,
Operating personnel's anthracemia is avoided while can be prevented effectively from what negative pressure cloth air duct was crumbled by big gun during headwork
Ventilation equipment.
Utility model content
The purpose of this utility model be in order to overcome the shortcomings of prior art exist, provide one kind can make operating personnel and
When understand driving face near carbonomonoxide concentration, avoid operating personnel's anthracemia and negative pressure can be prevented effectively from
The ventilation equipment for mine down-hole excavation operation that cloth air duct is crumbled by big gun during headwork.
The utility model is achieved through the following technical solutions：A kind of ventilation for mine down-hole excavation operation sets
Standby, including hoist engine, pulley, steel wire rope, local fan, negative pressure cloth air duct, electrical control cubicles and it is arranged near excavation operation face
Carbon monoxide concentration probe, the hoist engine include motor and the steel wire rope driving wheel being connected with the power output shaft of motor, institute
The front that pulley is rotatably arranged at the hoist engine is stated, the steel wire rope is arranged at the steel wire rope driving wheel with the cunning
Between wheel, pulley described in steel wire penetrating, the first half of steel wire rope and the equal coiling of the latter half of steel wire rope are in the steel wire
On rope driving wheel, former and later two terminations of steel wire rope are all fixedly connected with the steel wire rope driving wheel, and the local fan is arranged
In the side of the hoist engine, one end of the negative pressure cloth air duct is connected with the air outlet of the local fan, the negative pressure cloth
The other end of air duct is fixedly connected with the steel wire rope by draw ring, the hoist engine, the local fan, the carbon monoxide
Concentration probe is all electrically connected with the electrical control cubicles.
The side of the pulley is provided with location switch corresponding to the reach position that puts in place of the negative pressure cloth air duct, and this puts in place
Switch is electrically connected with the electrical control cubicles.
The beneficial effects of the utility model are：The utility model can make operating personnel be understood near driving face in time
Carbonomonoxide concentration, when the carbonomonoxide concentration near the driving face is higher, negative pressure cloth air duct is passed through by local fan
Fresh air is passed through in time, it is to avoid anthracemia hidden danger, it is ensured that the safety of operating personnel.Meanwhile, negative pressure cloth air duct is adopted
With the mode of steel wire rope telescopic moving, can be prevented effectively from and nearby be collapsed by big gun always situated in driving face because of negative pressure cloth air duct
Bad.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In in figure：1st, hoist engine；2nd, local fan；3rd, negative pressure cloth air duct；4th, steel wire rope；5th, draw ring；6th, location switch；7、
Carbon monoxide concentration probe；8th, pulley；9th, electrical control cubicles；10th, excavation operation face.
Specific embodiment
The utility model is described in detail below in conjunction with accompanying drawing.
As shown in figure 1, a kind of ventilation equipment for mine down-hole excavation operation, including hoist engine 1, pulley 8, steel wire rope
4th, local fan 2, negative pressure cloth air duct 3, electrical control cubicles 9 and the carbon monoxide concentration probe 7 being arranged near excavation operation face 10, volume
Raising machine 1 includes motor and 4 driving wheel of steel wire rope being connected with the power output shaft of motor, and pulley 8 is rotatably arranged at elevator
The front of machine 1, steel wire rope 4 are arranged between 4 driving wheel of steel wire rope and pulley 8, and steel wire rope 4 passes through pulley 8, before steel wire rope 4
, on 4 driving wheel of steel wire rope, former and later two terminations of steel wire rope 4 are all and steel for the equal coiling of the latter half of half part and steel wire rope 4
4 driving wheel of cord is fixedly connected, and local fan 2 is arranged at the side of hoist engine 1, one end of negative pressure cloth air duct 3 and local fan 2
Air outlet connection, the other end of negative pressure cloth air duct 3 is fixedly connected with steel wire rope 4 by draw ring 5, hoist engine 1, local fan 2,
Carbon monoxide concentration probe 7 is all electrically connected with electrical control cubicles 9.
Referring to Fig. 1, the side of pulley 8 is provided with location switch 6 corresponding to the reach position that puts in place of negative pressure cloth air duct 3, should
