Abstract

The invention discloses a ventilate blast-proof waterproof type support frame. The ventilate blast-proof waterproof type support frame comprises an up landing leg, an up support beam, a top beam, a down support beam, and a down landing leg. A first hydraulic cylinder is connected between the up landing leg and the top beam, a second hydraulic cylinder is connected between the down landing leg and the top beam. A ventilation device is fixedly connected with the lower surface of the top beam; shrinkage pools are formed in the up landing leg, down landing leg and the outside of the top beam. Pressure interaction devices are arranged at the inside of the shrinkage pools; and the up landing leg, the top beam and the down landing leg are respectively provided with a first processor, a second processor, and a third processor. The ventilate blast-proof waterproof type support frame further comprises an information transmission unit connected with the first processor, the second processor, and the third processor, the information transmission unit is used for receiving signals of the first processor, the second processor, and the third processor, and transfers the signals to the outside. The ventilate blast-proof waterproof type support frame is used for solving the problem that combustible gas in a coal mine shaft have sensor hysteresis in the prior art, realizes the purpose that the coal mine shaft supports a shaft wall, and at the same time, the safety under the shaft is improved.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to a ventilation and explosion-proof waterproof support frame. Background technique [0002] The supporting equipment in the coal mining face is the guarantee facility for the safe work of the coal mine, and its stability during use and the controllability of moving the frame are important indicators of this type of equipment. The existing hydraulic supports for fully mechanized mining can basically meet the safety and reliability requirements of medium-thick coal seam mining. The situation of major hazards in underground coal mines is complex, and factors such as mine pressure, gas, coal dust, fire, and water have had a serious impact on the safety of coal mine production in my country. The existing coal mine underground safety system is to detect and interpret combustible gas. This method easily leads to information lag. The combustible gas content in the mine can only be detected when...
