Abstract
The utility model relates to a braking device for a mining electric locomotive, in particular to a brake apparatus for the mining electric locomotive. The brake apparatus for the mining electric locomotive comprises a piston-type spring brake cylinder and brake pressure plates, wherein the piston-type spring brake cylinder is fixed on a locomotive body and is connected with a locomotive air source through an air duct; both bottom ends of the brake pressure plates are arranged at both sides of steel rails; the top ends of the two brake pressure plates are respectively hinged with the end part of a piston rod of the brake cylinder and the cylinder bottom of the brake cylinder through pin shafts; a connecting plate fixed on the locomotive body is arranged between the two brake pressure plates; both ends of the connecting plate are connected with the two brake pressure plates through pin shafts; and the air duct is provided with a control valve fixed on the locomotive body. The brake apparatus has a simple and reasonable structure, is simple to operate, is convenient to maintain and does not influence the finished locomotive adhesive force and the original braking effect of the locomotive in the braking process. The air source of the locomotive can be used without being added with other working mediums. The brake apparatus for the mining electric locomotive has excellent auxiliary braking effect. The reliability of a finished locomotive brake system is improved.
Description
Technical field
The utility model relates to the industrial-mineral electric locomotive brake equipment, specifically is a kind of industrial-mineral electric locomotive brake gear.
Background technology
The large-tonnage industrial-mineral electric locomotive of developing for the city underground shield-tunneling construction has adopted advanced brake system, when under the general gradient, transporting, and good braking effect, stable and reliable for performance, under the situation of conventional maintenance maintenance, braking failure can not take place or slip the car accident; But when the gradient reaches 35 ‰ when above (heavy grade transportation), under the operating mode of the heavily loaded upward slope operation of, locomotive wet and slippery at raceway surface, because of traction system or brake system generation catastrophic failure, when making the situation that locomotive is reversed, even with wheel lockup, wheel and rail also may produce slide relative, locomotive can't be stopped and slip car, can cause equipment and personnel's safety misadventure to construction.
Summary of the invention
Slide car situation takes place for avoiding the large-tonnage industrial-mineral electric locomotive in the utility model when heavy grade transports, a kind of industrial-mineral electric locomotive brake gear is provided.
The utility model is to adopt following technical scheme to realize: the industrial-mineral electric locomotive brake gear, comprise and be fixed in the piston type brake application by spring cylinder that links to each other with the locomotive source of the gas through airduct on the car body, the brake press plate that two bottoms place the rail both sides, the top of the two brake press plates cylinder bottom of the piston rod end by bearing pin and brake cylinder and brake cylinder respectively is hinged, be provided with the connecting plate that is fixed on the car body between two brake press plates, the connecting plate two ends are connected with two brake press plate bearing pins, and airduct is provided with the control cock that is fixed on the car body.When locomotive take place to slip the car accident or locomotive brake force when not enough, the driver operation control cock makes the elongation of brake cylinder action-piston rod, drive connecting plate, make the side of two brake press plate bottoms from rail outside malleation rail, produce bigger friction force with rail, force to make locomotive to stop with other brake system, thereby prevent to slip the generation of car accident.
The utility model can be selected to braking of wind brake mode or the braking of air draft brake mode: 1, brake to wind, pass through control cock, blow to brake cylinder, make the elongation of brake cylinder piston rod, distance increases between the two brake press plate tops, distance between the bottom reduces, and blocks rail, plays brake action; 2, air draft braking, when not giving wind, brake cylinder is under the contained spring effect, the piston rod elongation, brake press plate is formed top apart from increase, and the bottom distance reduces, and blocks rail, play brake action, when by control cock, blow to brake cylinder, then air pressure promotes piston, make length of spring compressed, alleviate braking.
Compared with prior art, the utility model is simple and reasonable for structure, and is simple to operate, easy to maintenance, and glancing impact does not influence the car load binding force, do not influence the original braking effect of locomotive.Can use the source of the gas work of locomotive itself, not need to increase other working medium.Have splendid auxiliary braking effect, increased the reliability of car load brake system.
