Description
(1) technical field:
The present invention relates to mine safety appliance, is to be used for a kind of intelligent travelling-preventing mine car manned, year ore deposit.
(2) background technology:
The inclined shaft rail is manned/and to carry an ore deposit mine car usually be that a main car drags three (or four) ore deposit buckets, by winch with hang over the steel rope on the main mine car hitch and mine car is risen to ground; But this mine car is in the tilt-lift process, if the disconnected rope of burst or when breaking off relations, just get out of hand immediately causes great derailing accident.The anti-sport car problem of inclined shaft is a thorny problem of being badly in need of solution during mine is produced always.
The scheme that addresses this problem at present has: (1) installs arrester, stop buffer in mine, stop, crotch stop buffer etc. directly stop mine car automatically; (2) by the running velocity of infrared detection device detection mine car, the employing wire net is kept off a car or the wire rope net bar is kept off a car; (3) utilize the brake spring tooth bar of upspringing automatically, drive the brake plug-in strip and be stuck on sleeper track under, mine car is braked; (4) utilize special-purpose brake wire to cooperate the braking car to realize the mine car brake; (5) utilize the wedge shape bloom to clamp rail and realize the mine car brake.
The shortcoming of above-mentioned the 1st, 2 schemes is: blocking apparatus can only disposablely use, and both waste material had destroyed the continuity that mine is produced again, required great effort again when handling accidental cost.Particularly manned mine car, the safety of passenger's life does not improve at all on the car.The shortcoming of the 3rd scheme is: load-carrying mine car out of control can produce the impulsive force about 10 tons, brake plug-in strip under the car is just as sharp knife is cut bean curd, one by one the sleeper that fixes on the ground is chopped off, or will pull out less than the railway spike on the sleeper of ground firm fixation one by one, steel sleeper is separated, and mine car is stopped incessantly at all.The 4th scheme implementation is difficulty very, mine disposes a long brake wire of hundreds of rice in addition and spends tens0000 yuan with the braking car, not only cost is too high, and brake wire how to support in roadway also be a difficult problem, brake wire is to the inhibition of cruising mine car also not to be sneezed at.The shortcoming of the 5th scheme is: the voussoir brake that the is hanging spark that not only braked, and no pooling feature, the rail locating accuracy that falls is lower, and behind the trouble-shooting, and to take out the wedge shape bloom difficult unusually by artificial.And detect, transmit disconnected rope signal by mechanical component, error is big, and reliability is low, and delay time is long.
