Abstract
The utility model discloses an underground air door interlocking device which belongs to interlocking devices and structurally comprises a balance weight, a balance weight bracket and an interlocking switch, wherein the balance weight comprises a first balance weight and a second balance weight; the balance weight bracket comprises a left balance weight bracket, a right balance weight bracket and a middle balance weight bracket; the left balance weight bracket, the right balance weight bracket and the middle balance weight bracket are respectively provided with slideways; the first balance weight and the second balance weight are respectively arranged between the left balance weight bracket and the middle balance weight bracket as well as between the right balance weight bracket and the middle balance weight bracket; the interlocking switch is arranged on the middle balance weight bracket; a first pulley and a second pulley are respectively arranged at the top parts of the left balance weight bracket and the right balance weight bracket; the first balance weight is connected with a first air door through a steel rope passing the first pulley; and the second balance weight is connected with a second air door through a steel rope passing the second pulley. The underground air door interlocking device has the characteristics of effectively avoiding the phenomenon of opening two groups of air doors simultaneously, eliminating the phenomenon of air current short circuit of the mine well, avoiding the gas accidents caused by poor ventilation and the like.
Description
Technical field
The utility model relates to a kind of interlock, especially a kind of underground air door interlock.
Background technology
Contact air door between the small-size coal mine air entering and returning tunnel is two groups, and under the normal condition, two groups of air doors are forbidden to open simultaneously; But because artificial origin; The situation that two groups of air doors are opened simultaneously happens occasionally, and very easily causes the mine air short circuit, even leads to the ventilating gas accident.At present, good solution is not also arranged.
The utility model content
The technical assignment of the utility model is to above-mentioned deficiency of the prior art a kind of underground air door interlock to be provided; This underground air door interlock has and has effectively prevented two groups of phenomenons that air door is opened simultaneously; Stop the mine air short circuit phenomenon, avoided leading to the ventilating gas accident characteristic.
The utility model solves the technical scheme that its technical problem adopted: it comprises counterweight, counter-balanced carriage and interlocking switch; Described counterweight comprises first counterweight and second counterweight; Described counter-balanced carriage comprises left counter-balanced carriage, right counter-balanced carriage and middle counter-balanced carriage; Be respectively arranged with slideway on described left counter-balanced carriage, right counter-balanced carriage and the middle counter-balanced carriage; First counterweight and second counterweight are separately positioned between left counter-balanced carriage, middle counter-balanced carriage and the right counter-balanced carriage, and on the counter-balanced carriage, the top of described left counter-balanced carriage and right counter-balanced carriage was respectively arranged with first pulley and second pulley in the middle of described interlocking switch was arranged on; Described first counterweight links to each other with first air door through the wire rope that passes first pulley, and second counterweight links to each other with second air door through the wire rope that passes second pulley.
Described interlocking switch is an equilateral right-angled triangle iron plate.
The underground air door interlock of the utility model is compared with prior art; Has following outstanding beneficial effect: effectively prevented two groups of phenomenons that air door is opened simultaneously, stopped the mine air short circuit phenomenon, avoided leading to the ventilating gas accident; Simple in structure, characteristics such as easy to use.

The specific embodiment
With reference to explanation at length below the underground air door interlock work of Figure of description 1 and 2 pairs of the utility model of accompanying drawing.
The underground air door interlock of the utility model; Its structure comprises counterweight, counter-balanced carriage and interlocking switch 8; Described counterweight comprises first counterweight 9 and second counterweight 7; Described counter-balanced carriage comprises left counter-balanced carriage 10, right counter-balanced carriage 6 and middle counter-balanced carriage 3; Be respectively arranged with slideway 12, the first counterweights 9 and second counterweight 7 on described left counter-balanced carriage 10, right counter-balanced carriage 6 and the middle counter-balanced carriage 3 and be separately positioned between left counter-balanced carriage 10, middle counter-balanced carriage 3 and the right counter-balanced carriage 6, and move up and down along slideway 12; Described interlocking switch 8 is arranged on the middle counter-balanced carriage 3; The top of described left counter-balanced carriage 10 and right counter-balanced carriage 6 is respectively arranged with first pulley 1 and second pulley 4, and described first counterweight 9 links to each other with first air door 11 through the wire rope 2 that passes first pulley 1, and second counterweight 7 links to each other with second air door 5 through the wire rope 2 that passes second pulley 4.
Described interlocking switch 8 is an equilateral right-angled triangle iron plate.
When the length of the wire rope 2 of described connection first air door 11 and second air door 5 was closed for the twice air door, first counterweight 9 and second counterweight 7 were in the extreme lower position of counter-balanced carriage respectively.When promoting interlocking switch 8, interlocking switch 8 can rotate along middle counter-balanced carriage 3.
Under the normal condition, first air door 11 and second air door 5 all are in closed condition, and interlocking switch 8 is in equilibrium state.When first air door 11 was opened, first counterweight 9 rose interlocking switch 8 is backed down, and this moment, interlocking switch 8 blocked second counterweight 7, and 5 of second air doors can't be opened; First air door 11 is closed, first counterweight, 9 return-to-home positions, this moment, interlocking switch 8 was in equilibrium state, at this moment opened second air door 5 again, then can second air door 5 be opened.Effectively prevent the phenomenon that first air door 11 and second air door 5 are opened simultaneously, stopped distinguished and admirable short circuit phenomenon.
Except that the described technical characterictic of manual, be the known technology of those skilled in the art.
