Abstract
An emergency brake device of a mining car comprises wheels and axles, also comprises a first chain wheel, a second chain wheel, a chain, a pawl shaft, a ratchet wheel, a pinion, a big gear, a screw rod, a nut, a slideway, a brake arm and a brake block, wherein the first chain wheel and the mining car rotates synchronously; the first chain wheel drives the pawl shaft through the chain; a pawl is not in contact with the ratchet wheel under the action of a spring in normal driving; when the mining car drives exceeding the allowed range of the driving speed, the pawl extends and acts with the ratchet wheel under the action of inertia and drives the pinion and the big gear for transmission, so as to brake the mining till the wheels stop rotating. Therefore, the emergency brake device of the mining car can effectively improve the safety of the transportation process, has simple structure, practicability and reliability and low cost and is an ideal emergency brake device of the mining car.
Description
Technical field
The utility model relates to a kind of rail mine car conveying arrangement, particularly a kind of mine car emergency braking apparatus.
Background technology
At present, the rail transportation is used in the China's coal-mine down-hole more, mine car self generally is not provided with brake equipment, and only stop buffer or catcher are set in the place on slope head, the end, slope, turnout, stop buffer can only stop vehicle uncontrolled slide in state to the slope end, and can not make mine car well braking in the downslide process, cause the dangerous of transportation.
Summary of the invention
Technical problem to be solved in the utility model is to overcome existing rail mine car conveying arrangement brake equipment, uneasy congruent drawback are not set, and provide a kind of simple and practical, safe and reliable, cost is low, and long service life can guarantee a kind of mine car emergency braking apparatus of transporting safely.
The technical scheme in the invention for solving the technical problem is: this mine car emergency braking apparatus, include wheel, axletree, be characterized in: it also includes first sprocket wheel, second sprocket wheel, chain, pawl axis, ratchet, miniature gears, big gear wheel, leading screw, nut, slideway, brake control lever, slipper, first sprocket wheel is located on the axletree, the top of axletree is provided with pawl axis, be provided with second sprocket wheel on the pawl axis successively, ratchet, miniature gears, be provided with chain between first sprocket wheel and second sprocket wheel, be provided with ratchet in the ratchet, spring, the ratchet attaching parts, the ratchet attaching parts is located on the pawl axis of axletree top, ratchet attaching parts two ends are respectively equipped with ratchet, be connected with spring between the ratchet other end and ratchet attaching parts arm, the glancing impact ratchet links to each other with ratchet, miniature gears is meshed with big gear wheel, and big gear wheel is provided with leading screw, nut, the leading screw bottom is provided with slideway, slideway successively with brake control lever, slipper links to each other, and the glancing impact slipper rubs mutually with wheel.
This mine car emergency braking apparatus provided by the utility model, it is a kind of mine car brake equipment in emergency circumstances, and after the mine car moving velocity surpassed allowed band, emergency braking apparatus began action, mine car is implemented braking, stop operating until wheel, thereby it can effectively improve the safety of transportation, simple in structure, practical reliable, cost is low, is a kind of comparatively ideal mine car emergency braking apparatus.
