Description

Przedmiotem wynalazku jest oslona liny kolowrotu bezpieczenstwa zwlaszcza dla kombajnów weglowych usytuowana w zastawkach scianowego przenosnika zgrzeblowego.Znane dotychczas konstrukcje kombajnów weglowych pracujacych w nachylonych wyrobiskach sciano¬ wych wyposazone sa w line bezpieczenstwa wspólpracujaca z kolowrotem bezpieczenstwa zlokalizowanym w chodniku nadscianowym. Swobodnie rozpieta i nieoslonieta lina stanowi stale zagrozenie dla zalogi przodka scianowego. Przyczyna licznych wypadków sa zwlaszcza ruchy poprzeczne liny spowodowane obciazeniami dynamicznymi lub zmianami kierunku pracy kombajnów. Swobodnie rozpieta i nieoslonieta lina utrudnia rów¬ niez w istotny sposób roboty w scianie.Oslona liny kolowrotu bezpieczenstwa wedlug wynalazku wyposazona jest w blachy oporowe zastawki przenosnika oraz elementy zamykajace oslaniajace od góry przestrzen otwarta oslony. Elementy zamykajace w postaci dzwigni dwuramiennych osadzone sa obrotowo na sworzniach przymocowanych do kadluba zastawek przenosnika. Elementy zamykajace znajduja sie w polozeniu zamknietym pod wplywem dzialania sprezyny.Lina bezpieczenstwa wprowadzana jest do oslony za pomoca uchwytów liny przymocowanych obok plozy maszyny.Zaletami oslony dla liny kolowrotu bezpieczenstwa jest bezpieczna praca dla zalogi przodka scianowego i bezzaklóceniowa praca urzadzen w scianie.Przedmiot wynalazku pokazano w przykladzie wykonania na rysunku, na którym fig. 1 przedstawia widok z przodu przedniej czesci kombajnu weglowego a fig. 2 - przekrój poprzeczny przez zastawke przenosnika.Oslona otacza line 1 kolowrotu bezpieczenstwa umocowana do kombajnu weglowego 2. Lina 1 znajdujaca sie przed kombajnem weglowym 2 umieszczona jest w przestrzeni oslonietej ograniczonej blachami bocznymi 3 i 4, blacha dolna 5 i elementami zamykajacymi 6. Elementy zamykajace 6 zamykane sa pod wplywem dzialania napiecia wstepnego sprezyny naciagowej 13 przymocowanej jednym koncem do dzwigni oporowej 12 elementu zamykajacego 6, a drugim koncem do kadluba zastawki 10. Lina 1 wprowadzana jest do oslony za pomoca uchwytu 7 umocowanego przy jednej z plóz 8 kombajnu weglowego 2. Element zamykajacy 6 osadzony jest obrotowo na sworzniu 9 przymocowanym do kadluba zastawki 10 przenosnika 11.2 113339 Zastrzezenia patentowe 1.

PLThe subject of the invention is a safety line for the safety turnstile, especially for coal harvesters, located in the valves of the wall scraper conveyor. The previously known designs of coal harvesters working in inclined wall excavations are equipped with a safety line cooperating with the safety turnstile located above the safety chain. A freely stretched and bare rope is a constant threat to the crew of a longwall face. The causes of many accidents are especially the lateral movements of the rope caused by dynamic loads or changes in the direction of the combine harvesters. A freely stretched and bare rope also makes it difficult to work in the wall. The rope cover of the safety turnstile, according to the invention, is equipped with stop plates of the conveyor valve and elements that protect the open area of the shield from the top. Closing elements in the form of two-arm levers are rotatably mounted on pins attached to the body of the conveyor valves. The locking elements are in the closed position due to the action of the spring. The safety rope is introduced into the guard by means of the rope grips attached next to the machine frame. The advantages of the guard for the safety turnstile rope are safe work for the crew of the wall face and trouble-free operation of the devices. in the example of the embodiment in the drawing, in which Fig. 1 shows a front view of the front part of the coal harvester and Fig. 2 - a cross section through the conveyor valve. The guard surrounds the line 1 of the safety winch attached to the coal harvester 2. The rope 1 is in front of the coal harvester 2 it is placed in a space limited by side plates 3 and 4, bottom plate 5 and closing elements 6. The closing elements 6 are closed under the effect of the pretension of the tension spring 13 attached at one end to the stop lever 12 of the closing element 6, and with the other end to the body 10 The rope 1 is introduced into the guard by means of a handle 7 attached to one of the skids 8 of a coal-shearer 2. The closing element 6 is rotatably mounted on a pin 9 attached to the body of the conveyor valve 10 11.2 113339 Patent claims 1. Rope cover of the safety reel, especially for coal-harvesters, characterized in that the rope (1) attached to the coal-loader (2) is placed in the space delimited by the side plates (3) and (4), the lower plate (5) and closing elements (6), the closing elements (6) open the contact surface of the handle (7) of the rope (1). 2. Cover according to claim A device as claimed in claim 1, characterized in that the rope (1) is led to the shield by means of a handle (7) attached to one of the skids (8) of the coal harvester (2). 3. Cover according to claim 1, with the alternative that it has a closing element (6) in the form of a pivot lever mounted on a pin (9) attached to the valve body (10) of the conveyor (11), while the stop lever (12) of the closing element (6) is attached to a tension spring (13), the other end of which is attached to the valve body (10).
