Abstract

The invention discloses a multi-stage inflation device used in a coal mine. The multi-stage inflation device comprises a pneumatic vehicle and an inflation device, wherein a gas multi-stage inflation device is used as the inflation device; a gas source gas inlet of the inflation device is divided into four parts through a four-way joint; one part is communicated with gas source gas inlets of a first pneumatic pressurization pump and a second pneumatic pressurization pump through a three-way joint I; the other parts are respectively communicated with driving gas inlets of the first pneumatic pressurization pump and the second pneumatic pressurization pump; gas outlets of the first pneumatic pressurization pump and the second pneumatic pressurization pump are gathered to form a gas path through a three-way joint III and then are sequentially communicated with a buffering tank, a gas bottle pressure gauge I, a pipeline switch IV and a gas source gas inlet of a third pneumatic pressurization pump; and a gas outlet of the third pneumatic pressurization pump is communicated with a gas outlet through an outlet pressure gauge II. The multi-stage inflation device performs inflation by using a gas source in an alley and is simple in structure, high in working efficiency, large in compression ratio and convenient and quick in inflation.

Description

technical field [0001] The invention relates to a multi-stage inflation device, in particular to a multi-stage inflation device for an aerodynamic mine vehicle used in underground coal mines. Background technique [0002] Prior art, publication number is " a kind of pneumatic vehicle " utility model patent of CN2267176, and it contains power, chassis, vehicle body, electrical equipment. The power is an air motor, which is installed on the chassis and connected with the flywheel with a coupling. The coupling includes a coupling sleeve and a coupling disc, which are connected by bolts, and the coupling sleeve and coupling disc are respectively connected with the air motor and the flywheel. The air source of the air motor is an air compressor unit, and the power of the air compressor unit is a generator set, which are all installed on the chassis. The advantages of the pneumatic vehicle: Compared with the power of the internal combustion engine, no pollutants such as hydrocar...
