Abstract
The utility model provides a tunneling working face well tunnel full-automatic safety device, which is installed at a tunneling working face air-return well tunnel opening, and used for preventing and controlling generation of the ''one ventilation and three preventions'' accident of the tunneling working face, The tunneling working face well tunnel full-automatic safety device is characterized in that, heavy type supports and the well tunnel four walls are firmly fixed to be an integration, a steel heavy type air door is installed between the heavy type supports of the well tunnel four walls, the steel heavy type air door is controlled by a hydraulic machine, and the hydraulic machine is controlled by a pressure sensor or a high temperature flue gas sensor, or a liquid level sensor, therefore, gas accidents, fire hazard accidents, and flood accidents generated at the tunneling working face are controlled to be in the minimal range, and treatment is performed.
Description
Technical field: driving face roadway automatic safety equipment belongs to a kind of safety equipment of installing in the underworkings of colliery, is specially adapted under the coal mine each access adit and installs and uses.
Background technology: through prevent the equipment of various natural calamities a lot of under the retrieval coal mine both at home and abroad comprehensively; But can be used in the outstanding equipment of automatic control fire, floods, coal and gas, all do not find both at home and abroad, the down-hole catches fire and mainly uses the fire dam fire sealing at present; It also mainly is shutoff that floods take place; And take place coal with gas when outstanding the measure means a lot, but also exist and can't fire expansion often occur with disaster control within the specific limits; Floods flood whole mine, and gas is outstanding to cause that significant explosion causes well to ruin serious accidents such as the people dies.
The utility model content: the purpose of the utility model is the problem to above-mentioned existence, through domestic and international visiting and learning and three more than ten years the coal mining accident management experience and test of many times invented this technology.
Driving face roadway automatic safety equipment is installed in driving face return airway road junction, in order to the generation of prevention and control driving face " one through three prevention " accident; It is characterized in that being one by fixedly securing between heavy supporting and the roadway wall; The steel heavy air door is installed between the heavy supporting of roadway wall, and the steel heavy air door is controlled by hydraulic press, and hydraulic press is by pressure sensor or high-temperature flue gas sensor or liquid level sensor control; When driving face generation coal and gas outstanding; And when producing pressure and affacting on the pressure sensor, pressure sensor control hydraulic press cuts out the steel heavy air door rapidly by hydraulic press; When the driving face breaking out of fire, high temperature or flue gas make high-temperature flue gas sensor control hydraulic press, rapidly the steel heavy air door are closed by hydraulic press; When driving face generation floods, liquid level sensor control hydraulic press cuts out the steel heavy air door rapidly by hydraulic press; Thereby gas accident, fire incident, floods accident that driving face is taken place are controlled at minimum zone, and handle.
Driving face roadway automatic safety equipment; It is dark to it is characterized in that 0.2 meter of rib is stretched in heavy supporting, and the heavy air door doorframe between the heavy supporting and the connecting mode of heavy supporting are steel plate, link through screw; Steel heavy air door door leaf and doorframe match; Heavy air door doorframe and door leaf connect for strand, and door leaf and hydraulic press are closed door leaf through drive link, and sensor is through the operation of relay control hydraulic press.
Driving face roadway automatic safety equipment all adopts the power supply of dual power supply and batteries; When the down-hole since accidental cause have a power failure; The batteries power supply is from the equipment power supply of trend driving face roadway automatic safety, when the down-hole restores electricity, and the automatic disconnection of batteries power supply.
Driving face roadway automatic safety equipment compared with prior art has the following advantages:
1, driving face roadway automatic safety equipment adopts the resistance to compression of high strength heavy type steel, antiknock, firm.
2, adopt combined type easy for installation, quick, can be with the moving of driving face, and can be repeatedly used.
3, can various accidents be controlled at the roadway mouth with the lining, avoid accident to enlarge and injure other place, down-hole.
4, be easy in time control the generation of various accidents, because hanging in advance of each sensor provides grace time for closing heavy air door.
5, realized " one through three prevention, the comprehensive regulation ", not only can ventilate, combat a natural disaster, take precautions against natural calamities, and realized the mine essential safe type.
6, the various sensors on the driving face roadway automatic safety equipment can with underground monitoring monitoring networking, and be transferred to ground and carry out Artificial Control and open.
7, driving face roadway automatic safety equipment has simple in structurely, and overall dimension is compact, and fault is few, and self-security is high, and can take precautions against natural calamities, can combat a natural disaster, but the also disaster relief.
Description of drawings:
