Abstract

Dynamiczne zabezpieczenie daszków pojazdów górniczych zawiera belke (103) mocowalna do podwozia pojazdu górniczego, do której przymocowane jest wirnikowe urzadzenie do przejmowania i rozpraszania energii uderzenia skal o daszek, przy czym urzadzenie do przejmowania i rozpraszania energii uderzenia zawiera przymocowany do ukladu belki (103) element bijakowy sprzezony suwliwie za pomoca bijakowych prowadnic z bocznymi scianami plyty korpusowej (13) mocowalnej do daszku, który wspólpracuje z co najmniej dwiema sprzezonymi szeregowo zebatkami osadzonymi suwliwie na prowadnicy przymocowanej do plyty korpusowej (13) i napedzajacymi kola zebate (9) wirnikowych akumulatorów energii kinetycznej (10, 11, 12), przy czym pomiedzy elementem bijakowym i pierwsza zebatka oraz pomiedzy zebatkami utworzone sa odstepy zapewniajace dzialanie elementów amortyzujacych i umozliwiajace przesuw elementu bijakowego wzgledem zebatek jak równiez przesuw tych zebatek wzgledem siebie, tak aby przesuwajacy sie element bijakowy przekazywal energie kinetyczna ruchu postepowego do wirnikowych akumulatorów energii kinetycznej (10, 11, 12) w celu jej przetworzenia na energie kinetyczna ruchu obrotowego.The dynamic protection of the roofs of mining vehicles includes a beam (103) fastened to the chassis of the mining vehicle, to which a rotor device for absorbing and dissipating energy of impact of scales against the roof is attached, the device for absorbing and dissipating impact energy includes an element attached to the beam system (103) flail slidably coupled by means of flail guides with side walls of the body plate (13) fastening to the roof, which cooperates with at least two teeth mounted in series mounted slidably on the guide attached to the body plate (13) and driving gear wheels (9) of rotor energy accumulators (10, 11, 12), with spaces between the beater element and the first sprocket and between the sprockets ensuring the operation of shock-absorbing elements and enabling the flail element to move relative to the sprockets as well as the shifting of these teeth relative to each other so that The flail element transmitted the kinetic energy of progressive motion to rotor accumulators of kinetic energy (10, 11, 12) in order to convert it into kinetic energy of rotational motion.
