Further, described undercarriage fixed seat 9 is installed in place, by described cylinder block 19, return spring seat 20 It is installed in place;Brake latching hole 4 in described brake is positioned between the brake latching hole 4 in vibration damper plate, used Brake latching 14 is connected;Elevating lever is joined with bolts with left and right vibration damper plate;By the fixed seat bolt in elevating lever Pin-and-hole 15 is arranged in undercarriage fixed seat 9, is connected with latching;Cylinder body suspension ring in described cylinder are connected with latching It is fixed on cylinder block 19;Connecting rod suspension ring connecting rod suspension ring 17 in described cylinder being fastened on latching on elevating lever connect Connect hole 17;Described return spring one end is arranged on return spring seat 20, the other end installs return spring on the brake Hanging hole 8;Related accessories electronic valve, controlling switch, circuit, compressed air piping in described lowering or hoisting gear are installed in place;I.e. Combination forms one group of railcar and directly rubbed formula emergency brake device;The each section compartment of described emergency brake device will typically install two Group or four groups.
A kind of railcar is directly rubbed the application method of formula emergency brake device, it is characterised in that carried out according to the following steps:
(1)Railcar is in normally travel state, release button switch, deenergization, and now in magnetic valve, intake valve is closed, Air bleeding valve is opened, under cylinder return spring and undercarriage return spring collective effect, and undercarriage drives brake stably to protect Hold the distance with rail definite value;
(2)Emergency is run into, it is necessary to which when stopping, long-press button switch switches on power, now in magnetic valve, and intake valve is opened, Exhaust valve closure, compressed air is promoted piston driving connecting rod to overcome return spring resistance, is pushed down on and risen and fallen by intake valve Frame, drives brake and rail friction, continues to push down on, and until vibration damper plate has a little bending, that is, reaches cylinder stroke design Maximum, now frictional resistance is maximum, keeps power on, until railcar parking;Continue to drive if necessary to release braking, Release button, deenergization, railcar is to return to normally travel state:
(3)When running into not clear situation in traveling way, button switch, constantly adjustment braking also can be discontinuously used according to driving experience Power, adjusts road speed, and parking is determined after situation or continues to drive safely until distinguishing.
Compared with prior art, present invention employs following new technology:
(1)The friction plate that the present invention takes and rail direct friction, reduce the loss of energy in brake force transmittance process;
(2)Friction Disk Surface shape is employed to be constructed with rail surface shape identical, increases friction area;
(3)It can be improved from the high material of coefficient of friction as friction plate with track friction coefficient, it is necessary to explanation, rail The wheel design of road car, should consider the endurance of wheel, to bear the weight in compartment and goods, consider optimal with rail again Frictional force, has been limited on selection wheel material;
(4)During friction plate and track direct friction, railcar is in walking, and the radiating effect of track is splendid, brakes over long distances When, brake force will not produce heat fade;
(5)The junction steel plate used in brake, can make railcar in turning, major and minor shoe plate occurs also with trade shape Respective curved is deformed, to keep its brake force constant;
(6)The vibration damper plate used on undercarriage, can be such that braking procedure more smoothes out.
Down time and stopping distance during the comprehensive railcar emergency brake short using Ke Ji great Shrink of above-mentioned new technology, Safety factor of travel is substantially increased, the present invention also has the advantages that:The friction plate of selection is small to rail damage, use It is long lifespan, simple in construction, easily fabricated, easy to operate, it is easy to maintenance, there is high use value.
