Vynález sa týká celkového rieženla pracovného orgánu stropného podavača výstuže,určeného na mechanizované vystužovanle banských chodieb.BACKGROUND OF THE INVENTION The present invention relates to an overall working body of a reinforcement ceiling feeder working on mechanized reinforced mining tunnels.

Doterajčí stav na vyznačuje tým, že zdvíhaťelný a otočný pracovny orgán stropnéhopodavača výstuže pozostáva z nosného ramena opatřeného výsuvnou doskou pozďfíucho tvaruna ktorej je uložená otočná donka zhodného tvaru opatřená držiakml stropných a bočnýchoblúkov vý3tuže chodby, pričom tieto sa výsuvnou doskou posúvajú v smere ramena a otá-čajú jednak okolo zvislého čapu v střede otočnej došky, ako aj okolo zvislých £apov nojednotlivých držiakoch. Nevýhodou tohoto stavu,Je, že neumožňuje pódia potřeby pri vy-stužování zdvíhat' stropně oblúky výstuže voči oblúkom bočným, takže nie je možné súčasnébudovanie stropných oblúkov výstuže pod stropom banskej chodby a přitom spúStanie bočnýcoblúkov výstuže k počve chodby. Nevýhodou dalej je to, že technologicky nutné dostreíova-nie stropných oblúkov výstuže v strope chodby sa vykonává otáčanía otočnej došky sc spo-ločnými držiakml na kterých sú uložené aj bočné oblúky, takže tieto sa pri otáčaní dostávajú voči závesnej dráhe podavača do výstrednej polohy, hoci to nie je technologicky po-třebné, ale přitom Skodlivo naktořajú celý podavač i so závěsnou dráhou do jednej strany,čo Je pracné velmi nebezpečné. Okrem toho, pohyb výsuvnéj desky je obmedzený zdvihom hy-draulického valca, čím je obmedzený aj dosah pracovného orgánu podavača, keň sa podavačnachádza na konci závesnej dráhy, takže Je nutné pridaí k nej pomocnú šekelu, do je ne-žiaduce z hiadiska prácnosti.The prior art is characterized in that the lifting and rotatable working member of the roof reinforcement bar consists of a support arm provided with a pull-out plate of which the swiveling donor of the same shape is fitted with a bracket of the ceiling and sidewalls of the corridor, the latter being moved in the direction of the arm and the swivel plate. they extend around the vertical pin at the center of the pivotable dock, as well as about the vertical paces of the individual holders. A disadvantage of this state is that it does not allow the reinforcement to raise the ceiling arches of the reinforcement against the arches laterally, so that it is not possible to simultaneously build the ceiling arches of the reinforcement under the ceiling of the mining passage while triggering the sidewalls of the reinforcement to the corridor. A further disadvantage is that the technologically necessary shearing of the ceiling arches of the reinforcement in the corridor ceiling is performed by turning and rotating the cantilever joints on which the lateral arches are also placed, so that, when rotated, they reach the eccentric position relative to the feeder track path, although it is not technologically necessary, but at the same time it harmfully tilts the entire feeder even with the suspension track to one side, which is very dangerous. In addition, the movement of the withdrawable plate is limited by the stroke of the hydraulic cylinder, thereby limiting the reach of the feeder's working member, while the feeder is at the end of the suspension track, so that an auxiliary shekel is added thereto.

Uvedené nedostatky sa odstraňujú pracovným orgánom stropného podavača výstuže pódiatohoto vynálezu, podstata ktorého spočívá v tom, že výsuvné zarladenle podávače pozostá-va z dvoch rovnoběžných nosníkov spojených naspodu spojovou doekcu, z reťazového pohonuumiestneného na nosníkoch vzadu, z vratnej kladky umiestnenej na nosníku vpředu ň z ťaž-nej reťaze prlpojenej predným úchytom a žádným úchytom k výsuvnému stolu uloženému klznena nosníkoch, dalej tým, že k výsuvnému zariadeniu je připevněné zdvíhacie zariadenie'svójím základným púzdrom opatřeným spddným úchytom zdvíhacieho valca, vnútorným úchytomzdvíhacej raťaze a napínacou skrutkou spHtnáj reťaze, přitom do základného púzdro Jeklzne uložené výsuvné púzdro s horným úchytom zdvíhacieho valca, s dnom na ktoroa Jeupevněný stípik opatřený zdvíhacou kladkou zdvíhacej reliaze a vo výsuvném púzdre je eSteklzne uložený výsuvný stlp opatřený horným ramenov presuvného zariadenla a dvojitým úchy-tem zdvíhacej reťaze ako aj spStnej reťaze a nakeniec tým, že k zdvíhaciemu zariadeniuje připevněné presuvné zariadenie pozostávajúce z horného ramena,na ktorom je připojenýpravý úchyt presuvného valca, ďalej z vodítok na ktorých sú objímky připevněné k presuv-nej doske opatrenej iavým úchytom presuvného valca. Výhodou pracovného orgánu stropného podavača výstuže podl’a tohoto vynálezu je, žestropně oblúky výstuže sú uložené no hornom ramene, ktoré je ovládané zdvíhacím zariade-ním, pričom bočnéOblúkysú uložené na výsuvnom stole, takže je súčasne možné budovaniestropných oblúkov pod stropom i spúSíanle bočných oblúkov výstuže k počve cho.tby. Vystře-dbvanie stropných oblúkov pri vystužovaní se vykonává presuvaním presuvnej došky s držiakmi' stropných oblúkov, pričom bočné oblúky sa s nimi nspresúvajú a teda ani nevystreďu-jú, ale zostávajú v strednej polohe, čím nedoohádza k nakláňaniu podavača a závesnejdráhy. Pohyb výsuvnej došky je rlešený reťazou, takže dosah pracovného orgánu podavačamož'e maí potrebnú velkost aj bez používania pomocnej sekcie dráhy.The aforementioned drawbacks are eliminated by the working member of the roof feeder of the present invention, the principle being that the retractable feeder of the feeder consists of two parallel beams connected at the bottom by a linking guide, from a chain drive mounted on the beams at the rear, from a return pulley located on the beam at the front. the heavy chain attached by the front grip and no grip to the pull-out table supported by the beams; Housing Sliding-seated retractable housing with upper lift roller mount, with bottom on which a fixed lift is provided with a lift lift lift pulley, and the retractable housing is equipped with a retractable mast fitted with by the upper arms of the transfer device and by the double grip of the lifting chain as well as the rear chain and the sling by attaching to the lifting device a sliding device consisting of an upper arm, on which is mounted a sliding gripper, further from the guides on which the sleeves are attached to the slider the plate with the removable roller holder. An advantage of the workpiece of the reinforcement ceiling feeder according to the invention is that the arcs of the reinforcement are placed on the upper arm, which is controlled by the lifting device, while the side flaps are placed on the extension table, so that the ceiling arcs below the ceiling and the side arcing of the reinforcement can be simultaneously built. to hear your mouth. Attention to the ceiling arches during reinforcement is carried out by sliding the sliding dock with the ceiling arch holders, the side arches not being compressed therewith and thus not centering, but remaining in the middle position, thereby avoiding tilting of the feeder and the suspension track. The movable dock movement is chained so that the reach of the feeder body can have the necessary size even without using the auxiliary track section.
