Description

Pierwszenstwo: ' Zgloszenie ogloszono: 11.09.1973 Opis patentowy opublikowano: 15.01.1975 75577 KI. 5c, 15/44 MKP E21d 15/44 czytelnia! Urzedu Patentowego 1 | Polnej IUeMYi-3.'* n L^ ej | Twórcywynalazku: Jan Domiczek, Anzelm Gosciminski, Stanislaw Zimowski Uprawniony z patentu tymczasowego: Fabryka Maszyn i Sprzetu Wiertniczego „Glinik", Gorlice (Polska) Hydrauliczny stojak kopalniany Przedmiotem wynalazku jest hydrauliczny stojak kopalniany pracujacy w ukladzie centralnego zasilania.Znana jest konstrukcja hydraulicznych stojaków kopalnianych, w których polaczenie korpusu z cylindrem lub z rura przedluzacza wykonano za pomoca spawania. Toznane rozwiazanie zmusza do stosowania na korpus, cylinder i przedluzacz stali przeznaczonych do spawania o nizszych wlasnosciach wytrzymalosciowych.Powoduje to do stosowania grubszych scianek cylindra i przedluzacza a w konsekwencji powiekszenie ciezaru calego stojaka. Równiez slaba strona spoiny jest pekanie zlacza podczas eksploatacji stojaków w kopalni.Celem wynalazku jest usuniecie wyzej opisanych niedogodnosci. Cel ten zostal osiagniety przez polaczenie korpusu z cylindrem lub z przedluzaczem zlaczem wciskanym zabezpieczonym drutem, a zlacze pomiedzy korpusem i cylindrem ma uszczelke o przekroju kolowym. Powierzchnia oporowa cylindra lub przedluzacza opiera sie o korpus powodujac dodatkowe uszczelnienie.Przez zastosowanie wynalazku uzyskano obnizenie ciezaru calego stojaka, oraz usunieto przypadki pekania zlacz podczas eksploatacji w kopalni.Przedmiot wynalazku jest przedstawiony w przykladzie wykonania na rysunku, który przedstawia srodkowa czesc stojaka.Jak uwidoczniono na rysunku korpus 1 polaczony jest z cylindrem 2 zlaczem wciskanym 3 zabezpieczo¬ nym drutem 4 oraz z przedluzaczem 5 zlaczem wciskanym 6 zabezpieczonym drutem 7. Dla uszczelnienia zlacza wciskanego 3 pomiedzy cylindrem 2 a korpusem 1 zastosowano gumowa uszczelke 8 o przekroju kolowym.Powierzchnia oporowa 9 cylindra 2 oraz powierzchnia oporowa 10 przedluzacza 5 opiera sie o korpus powodujac dodatkowe uszczelnienie i wzmocnienie zlacza.

'* N L ^ ej | Creators of the invention: Jan Domiczek, Anzelm Gosciminski, Stanislaw Zimowski Authorized by the provisional patent: Fabryka Maszyn i Sprzetu Wiertniczego "Glinik", Gorlice (Poland) Hydraulic mine stand The subject of the invention is a hydraulic mine stand working in the central power system. In which the connection of the body with the cylinder or with the extension tube is made by welding. This solution makes it necessary to use for the body, cylinder and extension steel intended for welding with lower strength properties. This results in the use of thicker walls of the cylinder and extension and, consequently, increasing the weight of the entire stand Also the weak side of the weld is the cracking of the joint during the operation of the props in the mine. The purpose of the invention is to eliminate the above-described disadvantages. This aim was achieved by connecting the body with a cylinder or with an extension cord with a push-in joint secured with a wire. em, and the connection between the body and cylinder has a O-ring gasket. The abutment surface of the cylinder or extension piece rests against the body causing additional sealing. By applying the invention, the weight of the entire rack was reduced, and the cases of cracking of the joints during mining operation were eliminated. In the drawing, the body 1 is connected to the cylinder 2 with a press-in joint 3 secured by a wire 4 and to an extension 5 with a push-in joint 6 secured by a wire 7. A rubber gasket 8 with circular cross-section is used to seal the press-in joint 3 between the cylinder 2 and the body 1. cylinder 2 and the abutment surface 10 of extension 5 abuts against the body for additional sealing and reinforcement of the joint.
