Abstract

Návrh rieši brzdu závěsných mobilných zariadení určených na používanie najmá na úklonných dráhách v stiesnených banských podmienkach. Jeho podstatou je, že brzdný válec má oporné veká opatřené na obvode symetricky proti sebe dvojitými okami obopínajúcimi pružinu nasunutá na brzdnom válci, pričom v dvojitých okách upevněné páky sú tvarovo prisposobené pružině a nepresahujú jej obrys v pozdížnej osi.The proposal solves the suspension of suspension mobile equipment for use bowing tracks in cramped mining conditions. Its essence is that it brakes the cylinder has support caps provided on the circumference symmetrically facing each other by double-meshed eyes spring on brake cylinders, fixed in double eyes the levers are shaped by a spring and do not exceed its outline in the longitudinal axis.

It is based on the fact that the brake cylinder has support lids with circumferentially symmetrically opposed double eyes surrounding the spring slid on the brake cylinder, wherein the levers fixed in the double eyes are spring-shaped and do not extend beyond the longitudinal axis.

Vynález sa týká brzdy závěsných mobilných zariadení určených na používanie najma na úklonných dráhách v stiesnených banských podmienkach.BACKGROUND OF THE INVENTION The present invention relates to the braking of overhead mobile devices intended to be used, in particular, on inclined tracks in confined mining conditions.

Brzdný mechanizmus závěsných mobilných zariadení, napr. lokomotiv, ťahačov a podobné je riešený obyčajne na mechanickohydraulickom principe. Brzdná síla je vyvíjaná pružinou cez pákový mechanizmus na čeluste a hydraulika alebo vzduch odbrzduje. Doposial' známe konštrukcie majú riešené upevnenie pák brzdným valcom v koncoch mimo valca. Nevýhodou uvedenej konštrukcie je rozmernosť zariadenia v smere osi valca, ktorá je limltujúcim činitelom šířky závěsných zariadení. Nevýhodou je tiež zložitý tvar pák. Uvedené riešenia pre vyššie brzdné sily sú rozměrné, čím je zhoršená prejazdnost závěsných mobilných zariadení cez výhybky, ako aj stiestnené miesta závesnej dráhy.Suspension mechanism for mobile mobile devices, eg. locomotives, tractors and the like is usually solved on the mechanical-hydraulic principle. The braking force is exerted by the spring via the lever mechanism on the shoe and releases the hydraulics or air. Previously known constructions have solved fastening of the levers by a brake cylinder at the ends outside the cylinder. A disadvantage of said construction is the dimensionality of the device in the direction of the cylinder axis, which is a limiting factor for the width of the suspension devices. Another disadvantage is the complex shape of the levers. Said solutions for higher braking forces are dimensional, thereby impairing the passability of the overhead mobile devices through the switches as well as the overhead locations of the overhead path.

Uvedené nedostatky sú odstránené brzdou závěsných mobilných zariadení podta vynálezu, ktorého podstata spočívá v tom·, že brzdný válec má oporné veká, opatřené na obvode symetricky proti sebe dvojitými okami smerujúcimi do středu a obopínajúcimi pružinu nasunutú na brzdnom válci, pričom v dvojitých okách upevněné páky sú tvarovo prispůsobené pružině a nepresahujú jej obrys v pozdížnej osi.These drawbacks are overcome by the brake of the mobile suspension devices according to the invention, characterized in that the brake cylinder has support lids, circumferentially symmetrically opposed by double eyes centered and enclosing a spring slid on the brake cylinder, the levers fixed in the double eyes they are spring-shaped and do not extend beyond the longitudinal axis.

Nový účinok brzdy podta vynálezu je najma v skrátení rozměru v ose valca a pre-The novel brake effect according to the invention is in particular in the reduction of the dimension in the cylinder axis and

Claims

A mobile towing device brake comprising, in particular, the jaws, brake pins, lever drive with brake cylinder and spring, characterized in that the brake cylinder (8) has support caps (9) provided with circumferentially symmetrically opposed double eyes for moving the levers from the critical point; thereby extending the possibility of use in operation in cramped mining conditions. The advantage is also that the brake has become more compact and less vulnerable to operation. This results in increased durability and reliability. Another advantage is also a reduction in weight compared to previous types for the same braking force.

BRIEF DESCRIPTION OF THE DRAWINGS The attached drawing shows an exemplary embodiment of a brake of a suspension mobile device according to the invention. In FIG. 1 is a front view of the brake and FIG.

2 side view.

The brake according to the invention consists of a double shoe 2, a pressure brake pin 3, levers 4 connected to a brake pin 3, a pin 5 and a suspension device 1 with a pin 6 and a pin 7 with a brake cylinder 8 with supporting lids 9. The piston rod 12 of the brake cylinder 8 is adapted to supply a pressurized fluid.

By supplying the pressure fluid via the piston rod 12 to the brake cylinder 8 which overcomes the force of the spring 11 and through the transmission of the levers 4 by acting on the brake pin 3, the jaws 2 are separated from the web of the suspension track 13. By releasing the pressure fluid from the brake cylinder 8, the spring 11 biased between the bearing caps 9, with double eyes 10, exerts a force through the levers 4 and the brake pin 3 on the shoe 2, which presses against the web of the suspension path 13.

OF THE INVENTION [10] directed towards the center and enclosing the spring (11i slid on the brake cylinder (8)), the levers (4) fixed in the double eyes (10) being adapted to the spring (11) and do not exceed its contour in the longitudinal axis.
