Description

Przedmiotem wynalazku jest strzemie zlacza obu¬ dowy górniczej z profili korytkowych.Znane dotychczas strzemiona obudowy podatnej z elementów korytkowych skladaja sie z jarzma, kablaka i nakretek. W innym rodzaju strzemion, kablak zastapiony jest ksztaltowa nakladka, pola¬ czona z jarzmem przy pomocy srub. Tego typu strzemiona posiadaja jedna zasadnicza wade. W czasie zsuwu polaczenia, kablaki strzemion ulegaja zukosowaniu i strzemiona zakleszczaja sie na la¬ czonych elementach. Przy dalszym narastaniu ob¬ ciazenia opór zakleszczenia zostaje pokonany i na¬ stepuje gwaltowny zsuw. W polaczeniu takim opór zsuwu jest zmienny i niejednokrotnie spada do ze¬ ra.Celem wynalazku jest skonstruowanie strzemie¬ nia którego charakterystyka pracy po osiagnieciu wymaganej warjosci ustala sie na stalym pozio¬ mie.Cel ten zostal osiagniety przez strzemie bedace przedmiotem niniejszego wynalazku.Strzemie wedlug wynalazku sklada sie z jarzma, ikafolaka i 'nalkrejteik, przy ¦-czyim jarzmo izacipatrzotne 10 20 jest we wsporniki, które koncami stykaja sie z ka- blakiem w poblizu jego narozy.Zaleta techniczna strzemienia wedlug wynalazku jest to, ze w czas,ie zsuwu nastepuje jego rów¬ nolegle przesuniecie na laczonych elementach, a ca¬ le polaczenie nie zmienia charakterystyki swej pra¬ cy.Przedmiot wynalazku uwidoczniony jest w przy¬ kladzie wykonania na rysunku, na którym fig. 1 przedstawia przekrój poprzeczny polaczenia wraz ze strzemieniem a fig. 2 przekrój podluzny. Strze* mie zlacza obudowy górniczej dla profili korytko¬ wych sklada sie z kablaka 1 jarzma 2 i nakretek 3. Jarzmo 2 zaopatrzone jest we wsporniki 4, które swymi wolnymi koncami stykaja sie z ka- blakiem 1, w poblizu jego narozy.Zastrzezenie patentowe Strzemie zlacza obudowy górniczej z profili ko¬ rytkowych, zlozone z jarzma, kablaka i nakretek, znamienne tym, ze jarzmo (2), zaopatrzone jest we wsporniki (4), które swymi wolnymi koncami sty¬ kaja sie z kablakiem (1) w poblizu jego narozy. 113 124113 124 F/g. / r 4 Flq. 2 .PZGraf.

The stirrups of a flexible housing made of trough elements known so far consist of a yoke, a cable and nuts. In another type of stirrup, the cable is replaced by a shaped cap which is connected to the yoke by means of screws. This type of stirrups has one major disadvantage. During the sliding of the connection, the stirrup cables are skewed and the stirrups jam on the connected elements. With a further build-up of the load, the jamming resistance is overcome and a rapid chute occurs. In such a combination, the thrust resistance is variable and often drops to zero. The aim of the invention is to construct a stirrup whose operating characteristics, after reaching the required value, are set at a constant level. This goal was achieved by the stirrups which are the subject of the present invention. The invention consists of a yoke, an icafolac and a nalkrejteik, while the yoke of which 10 20 is in brackets, which end up in contact with the cable near its corner. The technical advantage of the stirrup according to the invention is that at the time of Its parallel displacement takes place on the connected elements, and the whole connection does not change its performance characteristics. The subject of the invention is shown in the example of the embodiment in the drawing, in which Fig. 1 shows the cross-section of the connection with the stirrup, and Fig. 2 longitudinal section. The shackle of the mining support connectors for the trough profiles consists of a cable 1, a yoke 2 and nuts 3. The yoke 2 is provided with brackets 4, which with their free ends touch the cable 1, near its corners. connectors of the mining casing made of corrugated profiles, composed of a yoke, cable and nuts, characterized in that the yoke (2) is provided with brackets (4), which with their free ends contact the cable (1) near its corners. 113 124 113 124 F / g. / r 4 Flq. 2 .PZGraf.
