Abstract
The utility model discloses a kind of automatic control air door that can not simultaneously open, this automatic control air door is provided with the fixing doorframe of the other side's bodily form, the fixing side of doorframe is fixedly connected with the inwall of mine, one end is connected with dodge gate by jointed shaft in addition, two the interlock pistons separately established respectively one end are hinged and connected to through jointed shaft on the inwall on mine both sides, the interlock piston other end is hinged through expansion link and dodge gate, and the fluid chamber of two pistons is connected by a hydraulic oil pipe.Two air doors of this automatic control air door that can not simultaneously open are interrelated, switch each other, can avoid opening simultaneously, strengthen the stability of mine wind path, reduce the possibility that Human disturbance brings out accident, have important function to mine safety.
Description
Technical field
The utility model relates to a kind of mining automatic control air door, especially a kind of automatic control air door that can not simultaneously open.
Background technology
Air door forms the necessary a kind of device of ventilation system in mine, play the effect cutting off wind path, safety regulations in coal mine regulation air door can not be opened simultaneously, tradition air door is separate, by manual hand manipulation, the situation that easy appearance is opened simultaneously, causes wind path disorder, methane accumulation, bring out mine serious accident, therefore provide a kind of automatic control air door that can not simultaneously open just necessary.
Summary of the invention
In order to overcome the problem of easily opening, bringing out security incident that current mine air door exists simultaneously, the utility model provides a kind of automatic control air door that can not simultaneously open, two air doors of this automatic control air door that can not simultaneously open are interrelated, switch each other, can avoid opening simultaneously, strengthen the stability of mine wind path, reduce the possibility that Human disturbance brings out accident, to mine safety, there is important function.
The utility model solves the technical scheme that its technical problem adopts: this automatic control air door that can not simultaneously open comprises: fixing doorframe, jointed shaft, piston, expansion link, dodge gate, hydraulic oil pipe; This automatic control air door that can not simultaneously open is provided with the fixing doorframe of the other side's bodily form, the fixing side of doorframe is fixedly connected with the inwall of mine, side is connected with dodge gate in addition, two the interlock pistons separately established respectively one end are hinged and connected to through jointed shaft on the inwall on mine both sides, the interlock piston other end is hinged through expansion link and dodge gate, and the fluid chamber of two pistons is connected by a hydraulic oil pipe.
In actual use, when the dodge gate of one end is opened, the expansion link be connected with dodge gate is slowly pulled out from piston, and the hydraulic oil in another piston is retracted in this fluid chamber, piston in fluid chamber is withdrawn, thus by expansion link, another fan dodge gate is retracted closedown; In like manner, when the dodge gate of one end is closed, the expansion link be connected with dodge gate will slowly be pushed in piston, hydraulic oil is injected in another one piston, make the pressure increase of fluid chamber, thus by expansion link, an other fan dodge gate is opened, reach the object of two fan dodge gates switch each other.
The beneficial effects of the utility model are: two air doors of this automatic control air door that can not simultaneously open are interrelated, switch each other, can avoid opening simultaneously, strengthen the stability of mine wind path, reduce the possibility that Human disturbance brings out accident, to mine safety, there is important function.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural principle schematic diagram of the present utility model.
In Fig. 1,1. fixing doorframe, 2. jointed shaft, 3. piston, 4. expansion link, 5. dodge gate, 6. hydraulic oil pipe.
Detailed description of the invention
In Fig. 1, a kind of automatic control air door that can not simultaneously open, comprising: fixing doorframe 1, jointed shaft 2, piston 3, expansion link 4, dodge gate 5, hydraulic oil pipe 6; This automatic control air door that can not simultaneously open is provided with the fixing doorframe 1 of the other side's bodily form, the fixing side of doorframe 1 is fixedly connected with the inwall of mine, side is connected with dodge gate 5 in addition, two the interlock pistons 3 separately established respectively one end are hinged and connected to through jointed shaft 2 on the inwall on mine both sides, interlock piston 3 other end is hinged through expansion link 4 and dodge gate 5, and the fluid chamber of two pistons 3 is connected by a hydraulic oil pipe 6.
In actual use, when the dodge gate 5 of one end is opened, the expansion link 4 be connected with dodge gate 5 is slowly pulled out from piston 3, hydraulic oil in another piston 3 is retracted in this fluid chamber, piston in fluid chamber is withdrawn, thus by expansion link 4, another fan dodge gate 5 is retracted closedown; In like manner, when the dodge gate 5 of one end is closed, the expansion link 4 be connected with dodge gate 5 will slowly be pushed in piston 3, hydraulic oil is injected in another one piston 3, make the pressure increase of fluid chamber, thus by expansion link 4, an other fan dodge gate 5 is opened, reach the object of two fan dodge gates 3 switch each other.
