Description

Изобретение относитс  к черной ме- таппургии, в частности к оборудованию дл  вскрыти  чугунных леток доменной печи. Наиболее близйим к описываемому изоб ретению по технической сущности и достигаемому результату  вл етс  машина дл  вскрыти  чугунной летки доменной Печи, содержаща  ходовую тележку, устайавленную на монорельсе, и св занную с балкой, несущей приводную каретку с буром flj. Недостаток известной машины - возможность нарушени  устойчивости и самопроизвольного отхода балки во врем  вскр ти  летки и разборки ее футл ра из-за действи  реактивных усилий с возможными деформаци ми металлоконструкции при высоких TeMnepaiypax. Цепью изобретени   вл етс  повышение надежности работы за счет фиксации машины в период вскрыти  петки. Цепь достигаетс  тем, что св зь балки с тележкой выполнена в виде приводной подвески с рычагами, имеющей возможность продольного перемещени  по направл юшим , -закрепленным на тележке, при этом один из рычагов подвески выполнен регулируемым по длине. На чертеже изображена предлагаема  машина. На монорельсах 1 установлена ходова  тележка 2, в наклонных направп к щих 3 которой расположены опорные катки 4 подвески 5. На ходовой тележке размещен привод 6 подвески. При помощи шарниров 7 и 8 балка 9 св зана с подвеской, причем рычаг 10 выполнен регулируемым по длине. На балке расположена приводна  каретка 11 с подвешенным буром 12. Машина работает следующим образом . В исходном положении катки 4 подве ки 5 наход тс  в верхней части наклонных направл ющих 3 ходовой тележки 2, При этом передний конеТа подвески 5 с шарниром 7 расположен вне габаритов фурменных приборов и стационарных площадок, что дает возможность бесThe invention relates to black metaphoria, in particular to equipment for opening pig-iron letters of a blast furnace. The closest to the described invention to the technical essence and the achieved result is a machine for opening a pig-iron notch of a Blast Furnace, containing a traveling trolley mounted on a monorail and connected to a beam carrying a drive carriage with a flj drill. A disadvantage of the known machine is the possibility of violation of the stability and spontaneous withdrawal of the beam during the opening and dismantling of its case due to the action of reactive forces with possible deformations of the metal structure at high TeMnepaiypax. The chain of the invention is to increase the reliability of operation due to the fixation of the machine during the opening of the bat. The chain is achieved by the fact that the link between the beam and the trolley is made in the form of a drive suspension with levers that can be longitudinally displaced in directions, fixed on the trolley, while one of the suspension arms is adjustable in length. The drawing shows the proposed machine. On the monorails 1, a trolley 2 is installed, in which inclined guides 3 there are support rollers 4 of the suspension 5. The drive 6 of the suspension is placed on the trolley. With the help of hinges 7 and 8, the beam 9 is connected to the suspension, with the lever 10 being adjustable in length. On the beam is located drive carriage 11 with a suspended drill 12. The machine works as follows. In the initial position, the rollers 4 of the suspension 5 are located in the upper part of the inclined guides 3 of the undercarriage 2, while the front end of the suspension 5 with the hinge 7 is located outside the dimensions of the tuyere assemblies and fixed platforms, which makes it possible to
