Abstract
The utility model concerns a simultaneous interlocking device used for big and small wind doors in underground mines. The device mainly comprises a big winddoor (5) fixed on a door wall (7) and a small wind door (6) opened in the big wind door (4). The features are that an interlinkage device is installed between the big winddoor (4) and the samll one (6) and the set of interlinkage device is connected with another set through a transmission rope. The advantages of the utility model lie in that simultaneous interlockage can be realized and flexible switches make it convenient for the personnel to pass through and it is simply structured and easily operated. And a more steady flow of wind can be kept for transport vehicles and pedestrians even though one channel is open with the other two closed.
Description
(1) technical field
The utility model relates to the interlock of mine ventilation facility, particularly a kind of mining underground air door interlock.
(2) background technology
At present, along with the raising of mining mechanization degree, large-scale highly efficient and productive mine quantity constantly increases.For dealing with the needs of main equipment and high-efficiency mining, the air output of its down-hole also will increase, and the opening resistance of corresponding underground air door also increases.It is to guarantee that each face air volume is stable and mobile that the air door purpose is set in the ventilation system in the connection roadway of down-hole; Avoid distinguished and admirable short circuit, can dilute " gas " concentration, can reduce the work plane temperature.So the air door management is the important step of ventilation system management,, bring great harm will for work plane thereafter in case " short circuit " takes place from certain air door.But because air door both sides blast is big, a general people opens relatively difficulty separately, and a lot of mining areas all are to offer little air door again to be convenient to personnel's turnover on big air door.According to the needs of safety in production, all air doors all are that twice or three roads are formed.Promptly work as a door opening and advance, another air door will be closed, and guarantee the normal circulation of air-supply.For reaching this purpose, between the twice air door, interlock is set.The big air door of twice or the little air door of twice of interlocking separately but interlock originally can only be interlocked separately, interlocking when can not realize large and small air door.So big air door often occurs or little air door is not closed phenomenon, ventilation system " short circuit " takes place easily, bring serious hidden danger to safety in production.
(3) technology contents
In order to solve the deficiency of original interlock, the utility model provides mining down-hole size air door interlock simultaneously.
The purpose of utility model according to following technical scheme realize.Comprise the big air door that is fixed on the wall in this interlock, offer little air door on big air door, structure is for being provided with interlock setting between big air door and little air door, and the big or small throttle setting of such cover is connected with another set of big or small throttle setting by transmission rope.
Above-mentioned linkage is on big air door two pulleys to be set, and transmission rope one end is fixed on the little air door, and the other end is arranged on the big air door and is fixed on another little air door behind two pulleys through being arranged on two pulleys on the big air door and one.
On described door wall, establish lacing hole, pulley is installed in the hole, transmission rope one end is fixed on the little air door, behind restrict on rope hole and another wall on two pulleys on the big air door, the door wall hole, strong wind door guide roller the other end of transmission rope is fixed on another little air door then.
Superiority of the present utility model is to realize that big or small air door interlocks simultaneously, and switch is convenient to personnel flexibly and is passed through.Simple in structure, be easy to realize.Be open to traffic or during the pedestrian, and though open wherein any together, twice are all closed in addition, make distinguished and admirable more stable.
(4) description of drawings
Accompanying drawing is a structure chart of the present utility model.
1. pulley, 2. transmission rope, 3. rope hole, 4. big air door, 5.A pulley, 5B pulley, 6 little air doors, 7 rope holes.
(5) specific embodiment
Structure of the present utility model is referring to accompanying drawing.Having big air door 4 on the door wall, opening little air door 6 on the air door 4 greatly, between the big or small air door linkage is set, the big or small air door linkage of such cover is connected with another set of big or small air door linkage by transmission rope 2.
Described linkage is on big air door 4 two pulley 5A, 5B to be set, transmission rope 2 one ends are fixed on the little air door 6, and the other end is arranged on the big air door 4 and is fixed on another little air door 6 behind two pulley 5A, 5B through being arranged on two pulley 5A, 5B on the big air door 4 and another.
In general interlock directive wheel (pulley) position of big air door 4 in little air door 6 central upper.The directive wheel of chain little air door 6 is installed in angle on the little air door door-hinge.Utilize the effect of guiding device that rope capacity rationally is set, guarantee that one air door (little air door or big air door) opened after, other one air door closed simultaneously.When three road air doors being set, then connect with second road, the 3rd road respectively by the inlet side first road air door as one group.Like this, three road air doors are closed simultaneously at ordinary times, be open to traffic or during the pedestrian, though open wherein any together, twice are all closed in addition, make distinguished and admirable more stable.No matter be twice or three road air doors, the distance that length of steel wire rope should equal to close simultaneously the twice air door adds the distance of opening one air door, otherwise does not have the effect of closing another road air door.
Claims (3)
1, interlock of big or small air door while of mining down-hole, mainly by the big air door (5) that is fixed on the wall (7), the little air door (6) that is opened on the big air door (4) is formed, it is characterized in that between big air door (4) and little air door (6) linkage being set, the big or small air door linkage of such cover is connected with another set of big or small air door linkage by transmission rope (2).
