Description

Przedmiotem wynalazku jest górnicza obudowa oslonowo-podporowa, wyposazona w hyd¬ rauliczny przesuwnik polaczony z stropnica i z oslona zawalowa.Znana w technice, górnicza obudowa oslonowo-podporowa majaca tloczysko przesuwnika polaczane z oslona a cylinder z stropnica (lub odwrotnie) w przypadku, gdy parcie górotworu przekroczy dopuszczalna wartosc narazona jest na nagle zniszczenie lub uszkodzenie wspomnia¬ nego przesuwnika stropnicowego. Dzieje sie tak dlatego, ze zwiekszone ponad dopuszczalna wartosc parcie górotworu powoduje nadmierne rozwarcie stropnicy i oslony, a w konsekwencji wyrwanie tloczyska z cylindra przesuwnika. Nagle zniszczenie przesuwnika stwarza bardzo powa¬ zne zagrozenie dla bezpieczenstwa zalogi oraz ma istotny wplyw na wydajnosc i organizacje pracy, zwlaszcza w zmechanizowanych przodkach wydobywczych, gdzie niszczenie lub uszkodzenie nawet jednego z urzadzen powoduje koniecznosc unieruchomienia lub znacznego ograniczenia wydajnosci pracy urzadzen wspólpracujacych i towarzyszacych.Celem wynalazku jest wyeliminowanie tych istotnych, dla praktyki, niedogodnosci a zagad¬ nieniem technicznym wymagajacym rozwiazania jest opracowanie ukladu ograniczajacego oraz stabilizujacego kat rozwarcia pomiedzy stropnica a oslona zawalowa w przypadku, gdy parcie górotworu na przegub laczacy stropnice z oslona przekroczy dopuszczalna wartosc dla okreslonej wysokosci pracy obudowy.Zgodnie z wynalazkiem, zagadnienie to zostalo skutecznie rozwiazane, dzieki ternu ze obu¬ dowa oslonowo-podporowa wyposazona jest uklad blokujacy, uniemozliwiajac} calkowite wysu¬ niecie sie tloczyska z cylindra przesuwnika stropnicowego. Uklad blokujacy ma postac trójkata, w którego wierzcholku usytuowany jest wspomniany przegub laczacy stropnice z oslom*, a w pozo¬ stalych wierzcholkach, z których jeden umieszczony jest w stropnic/a drugi w oslonie. znajduja sie zamocowania polaczone ze soba za pomoca ciegna, którego dlugosc, w stanie naprezonym, równa jest dluzszemu bokowi wspomnianego trójkata.Tak rozwiazane zagadnienia techniczne zapewnia calkowite zabezpieczenie przesuwnika stropnicowego w przypadku, gdy parcie górotworu na przegub przekroczy dopuszczalna wartosc.2 128 036 Ponadto uklad blokujacy jesi bardzo pomocny podczas wymiany przesuwnika oraz podczas wszelkiego rodzaju remontów, gdy wymagana jest stabilizacja kata rozwarcia pomiedzy stropnica a oslona.Przedmiot wynalazku uwidoczniony jest w przykladzie wykonania na rysunku przedstawiaja¬ cym obudowe ogonowo podporowa w widoku z boku.Jak pokazano na rysunku, obudowa majaca stropnice 1 polaczona przegubowo z zawalowa oslona 2 oraz zaopatrzona w hydrauliczny, stropnicowy przesuwnik 3, wyposazona jest w bloku¬ jacy uklad majacy postac trójkata ABC. W wierzcholku A znajduje sie przegub laczacy stropnice 1 z oslona 2, a w wierzcholku B usytuowanym w stropnicy (l)oraz w wierzcholku C usytuowanym w oslonie (2) — znajduja sie zamocowania ciegna 4, którego dlugoscjest równa najdluzszemu bokowi trójkata, a odcinki a i c (zaznaczone liniami przerywanymi) stanowia pozostale jego dwa boki.Zastrzezenie patentowe Górnicza budowa oslonowo-podporowa, zaopatrzona w hydrauliczny przesuwnik stropni¬ cowy, znamienna tym, ze wyposazona jest w uklad blokujacy majacy postac trójkata (ABC), w którego wierzcholku (A) znajduje sie przegub laczacy stropnice (1) z zawalowa oslona (2), a w wierzcholku (B) usytuowanym w stropnicy oraz w wierzcholku (C) usytuowanym w oslonie, znajduja sie zamocowania ciegna (4), którego dlugoscjest równa najdluzszemu bokowi wspomnia¬ nego trójkata.Pracownia Poligraficzna UP PRL. Naklad 120 egz.Cena 100 zl PLThe subject of the invention is a mining shield and support casing, equipped with a hydraulic shifter connected to the canopy and a cave guard. Known in the art, mining guard and support casing having a shifter rod connected to the guard and the cylinder with the canopy (or vice versa) the rock mass exceeds the permissible value, the risk of sudden destruction or damage of the said roof shifter is at risk. This is because the increased pressure of the rock mass above the permissible value causes excessive opening of the canopy and the cover, and consequently the pulling of the piston rod from the shifter cylinder. Suddenly, the destruction of the shifter poses a very serious threat to the safety of the crew and has a significant impact on the efficiency and organization of work, especially in mechanized mining faces, where the destruction or damage of even one of the devices necessitates the immobilization or significant reduction of the efficiency of cooperating and accompanying devices. The invention is to eliminate these inconveniences, significant for practice, and the technical issue that requires a solution is to develop a limiting and stabilizing system for the opening angle between the canopy and the collapsing shield in the event that the rock mass pressure on the joint connecting the canopy with the shield exceeds the allowable value for a specific height of the support According to the invention, this problem has been successfully solved, thanks to the box with the support and casing equipped with a locking system, preventing the complete extension of the piston rod from the roof shifter cylinder. nothing. The locking system is in the form of a triangle, in the apex of which the said joint joining the canopy with the donkey is located, and in the other vertices, one of which is placed in the canopy and the other in the casing. There are fastenings connected with each other by means of a link, the length of which, in the tensioned state, is equal to the longer side of the triangle. Technical issues solved in this way ensure complete protection of the roof shifter in the event that the rock mass pressure on the joint exceeds the permissible value. 2 128 036 Moreover, the system The blocking device is very helpful when replacing the shifter and during all kinds of repairs, when stabilization of the opening angle between the canopy and the cover is required. The subject of the invention is shown in the example of the embodiment in the drawing showing the tail-support casing in a side view. As shown in the figure, the casing having the roof rails 1 articulated with the cave cover 2 and provided with a hydraulic, overhead shuttle 3, it is provided with a blocking arrangement in the form of a triangle ABC. In top A there is a joint connecting the canopy 1 with the cover 2, and in the top B situated in the canopy (l) and in the top C located in the cover (2) - there are tie rod fasteners 4, the length of which is equal to the longest side of the triangle, and the sections a and c ( marked with dashed lines) are its other two sides. Patent claim Mining casing and support structure, equipped with a hydraulic taper shifter, characterized by the fact that it is equipped with a locking system in the form of a triangle (ABC), in which the apex (A) is located a joint connecting the canopy (1) with the folded cover (2), and in the apex (B) located in the canopy and in the top (C) situated in the cover, there are tie rod fasteners (4), the length of which is equal to the longest side of the triangle.
