Abstract
The utility model relates to a mechanical automatic closing interlock device for a mine air door, which comprises a flexible rope and two fixed pulleys; one end of the flexible rope is fixed on a door leaf AAn and the other end is fixed on a door leaf B by passing around the two fixed pulleys and penetrating a door-wall. With simple structure, easy use and low cost, the utility model is proved safe and feasible through the field installation experiment. At least one air door of the two air doors is in close state all along by the utility model with reduced air quantity loss and reduced energy consumption; the accident of the short circuit of the air flow and the deficiency of air quantity because of the open of the air door can be avoided. The utility model can be used for the storage facility for isolating the medium, such as air, etc. in the coal mine of the underground mining, other metal and non-metal minerals, etc.
Description
The utility model belongs to the mine ventilation facility, is specifically related to the self-closing interlock of a kind of Air Throttle in Mine Pit machinery.
In order to get rid of down-hole pernicious gas and combustible dust, all kinds of mines have all designed ventilation system.All must there be wind circulation continuously in each operation place, down-hole (especially stope), and air quantity must reach certain requirement.In order to prevent distinguished and admirable short circuit, some tunnels, down-hole need completely cut off, but pedestrian's driving is also wanted in these tunnels, thereby are provided with air door.Air door is established twice for every group in accordance with regulations, and twice can not be opened simultaneously.But often owing to reasons such as air door structure, construction quality and personal managements, the twice air door opens wide simultaneously and is not related to the phenomenon ubiquity that causes distinguished and admirable short circuit, causes with wind place deficiency in draught, and is usually accidents caused thus.For fear of the generation of above-mentioned situation, some mine sends the special messenger to keep an eye in the place that air door is set.Also have the minority mine to adopt the electronic auto-control air door, but because its complex structure, cost is higher, be difficult for promoting the use of.
The purpose of this utility model provide a kind of simple in structure, easy to install, need not the special messenger guard can realize the control device of the self-closing and interlocking of Air Throttle in Mine Pit.
Technical solution of the present utility model is: be positioned at door wall one side of air door door-hinge, be provided with fixed pulley, an end of flexible rope is fixed on the door leaf A, and the other end is walked around two fixed pulleys, passes a wall, is fixed on the door leaf B.
Above-mentioned flexible rope is fixed on any of door leaf A, B top axle far away side.This flexible rope is wire rope, anchor chain or the nylon rope that spring is housed.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Accompanying drawing is the utility model structural representation.
Wherein: 1, blast direction 2, wire rope 3, fixed pulley 4, door wall 5, door-hinge 6, fixed pulley 7, door leaf A 8, door leaf B 9, door opening direction
As shown in the figure, be fixed on any of door leaf A7 top axle far away side according to blast direction 1 and the end of door opening direction 9 wire rope 2.Wire rope 2 is walked around the fixed pulley 3 of door wall 4 one sides that are positioned at air door door-hinge 5, passes a wall 4, walks around fixed pulley 6 again, is fixed at last on any of door leaf B8 top axle far away side.
During use, according to the angle of distance between the two fan doors and door unlatching, choose reasonable length of steel wire rope.Under the normal condition, the twice air door is closed simultaneously under the effect of wire rope gravity and elastic force, and this i.e. " self-closing ".A is in opening-wide state when air door, and people or car in the process of opening air door B, drive wire rope by A behind the door thereupon, make air door A closure.Otherwise, when opening air door A, if air door B is in opening-wide state, also can be with the unlatching of air door A closure, this is " interlocking ", the twice air door is had at least be in closed condition together all the time.If air door is biparting structure, can two groups of identical devices be installed according to said method and gets final product.
The utility model compared with prior art its advantage is: simple in structure, easy to use, with low cost, and safe and reliable, truly feasible through on-the-spot installation test proof. Adopt this device, the twice air door is had at least be in all the time together closed condition, reduced wind loss, reduced energy consumption, avoided being not related to the Air escape branch deficiency in draught because air door is unlimited and caused the accident. This device can be used for colliery and other metallic ore, the nonmetallic ore of pit mining and needs storage facilities of the media such as air-isolation etc.
