Description
Przedmiotem wynalazku jest kotew górnicza do kotwie¬ nia elementów obudów górniczych oraz górotworu.The subject of the invention is a mining bolt for bolts elements of mining supports and rock mass.
Znane kotwie górnicze skladaja sie z ciegna, w postaci preta stalowego oraz spoiwa którym najczesciej jest spoiwo cementowe lub spoiwo oparte na zywicach chemoutwar- 5 dzalnych najczesciej poliestrowych. Pret stalowy zakon¬ czony jest gwintem na który nakrecona jest nakretka i wlozona podkladka dokrecona do calizny wyrobiska.The known mining bolts consist of a tie rod in the form a steel rod and a binder, which is most often a binder cement or a binder based on chemically 5 resins most often polyester. Steel pretzel it is connected with a thread on which a nut and is screwed on inserted washer tightened to the entire pit.
Inny rodzaj kotwi górniczych opisany jest w paten- . cie polskim nr 84142. Kotew wedlug tego wynalazku 10 sklada sie ze spoiwa oraz wiazki wlókien poliestrowych lub akrylowych. Kotwi metalowych nie mozna stosowac do kotwienia pokladu wegla, gdyz przy urabianiu mecha¬ nicznym ulegaja niszczeniu noze kombajnu.Another type of mining bolts is described in the patent . Polish No. 84142. Anchor according to this invention 10 consists of a binder and bundles of polyester fibers or acrylic. Metal anchors cannot be used for bolting the deck of coal, because when working with moss the knives of the combine are damaged.
Inna niedogodnoscia stosowania tych kotwi jest duza 15 pracochlonnosc przy obróbce mechanicznej, to jest gwin¬ towaniu kotwi oraz dokrecaniu nakretek czesto zanie¬ czyszczonych spoiwem gwintów. , Kotew wedlug wynalazku polskiego, patent nr 84142, posiada podobne niedogodnosci dotyczace gwintowania 20 koncówek, a poza tym wymaga jeszcze dodatkowo wyso¬ kiej pracochlonnosci przy formowaniu preta z luznych wlókien syntetycznych. Wszystkie opisane niedogod¬ nosci, nie wystepuja w kotwi wedlug wynalazku.Another disadvantage of using these bolts is the large 15 laboriousness in machining, ie thread bolts and nuts are often tightened binder-cleaned threads. , Anchors according to the Polish invention, patent no. 84142, has similar drawbacks to threading 20 tips, and additionally requires an additional high effortless when forming rods from loose synthetic fibers. All the described disadvantages nodes are not present in the bolt according to the invention.
Kotew wedlug wynalazku, do kotwienia elementów 25 jobudów górniczych oraz górotworu, sklada sie z ciegna spoiwa. Ciegno w postaci preta, korzystnie z wlókna szklanego, posiada w jednym koncu zgrubienie o korzyst-' nym ksztalcie, na które nalozona jest podkladka, nato¬ miast w drugim koncu ciegna umieszczone sa poprzeczne 30 sworznie. W koncu przeciwleglym dó konca ze sworznia¬ mi poprzecznymi znajduje sie wyciecie poprzeczne.An anchor according to the invention for anchoring elements 25 jobudów mining and rock mass, consists of a cable binders. Rod in the form of rods, preferably of a fiber glass, has a thickening at one end with a favorable shape on which the washer is placed, At the other end, the cables are transverse 30 pins. At the opposite end to the end with a pin m and the cross section has a cross cut.
Innym rodzajem przedstawionej kotwi jest to, ze ciegno w postaci preta korzystnie z wlókna szklanego, posiada w jednym koncu nakladke pierscieniowa o ksztalcie stoz¬ ka, zabezpieczona przed zsunieciem z ciegna, sworzniem poprzecznym. W drugim koncu ciegna umieszczone sa poprzeczne sworznie. Na nakladke pierscieniowa o ksztal¬ cie stozka nalozona jest podkladka. W koncu przeciwle¬ glym do konca ze sworzniami poprzecznymi znajduje sie wyciecie poprzeczne.Another type of anchor depicted is that of a tendon in the form of a rod, preferably made of glass fiber, has a cone-shaped ring at one end board, secured against sliding with a pin transverse. At the other end, the cables are placed transverse pins. Shaped ring overlay The cut of the cone is overlaid with a washer. Finally, the counter The glym end with transverse pins is located cross cut.
Zaleta kotwi wedlug wynalazku jest jej prosta budowa, prostota jej zabudowy w warunkach górniczych, gdyz bolce poprzeczne spelniaja jednoczesnie role mieszadel w przypadku stosowania zywic chemoutwardzalnych i jej obrotu w otworze wyrobiska górniczego, jak i zwiekszaja jej utwierdzenie.The advantage of the bolt according to the invention is its simple structure, the simplicity of its construction in mining conditions, because transverse pins also act as agitators in the case of using chemosetting resins and her turnover in the mine excavation bore and increase its strengthening.
Przedmiot wynalazku przedstawiony jest w przykla¬ dzie wykonania na rysunku, na którym fig. 1 przedsta¬ wia kotew górnicza w przypadku zgrubienia jej konca, a fig. 2 kotew górnicza z nakladka pierscieniowa o ksztal¬ cie stozkowym z bolcem poprzecznym.The subject matter of the invention is shown in the example below the day of implementation in the drawing in which Fig. 1 shows a mining anchor is made in the case of a thickening of its end, and Fig. 2 a mining bolt with a ring-shaped overlay taper cut with transverse pin.
Jak wynika z fig. 1, kotew górnicza wedlug wynalaz¬ ku sklada sie z ciegna w postaci preta 1, korzystnie z wlók¬ na szklanego, który posiada w jednym koncu zgrubie¬ nie, 2, o korzystnym ksztalcie, na które nalozona jest pod¬ kladka 3. W drugim koncu ciegna 1, umieszczone sa po¬ przeczne sworznie 4. W koncu przeciwleglym do konca ze sworzniami poprzecznymi 43 znajduje sie wyciecie poprzeczne 7. 105 172105 172 3 Odmienne rozwiazanie kotwy górniczej uwidocznio¬ ne na fig. 2 przedstawia kotew skladajaca sie z ciegna i spoiwa, przy czym ciegno w postaci preta 1, korzystnie z wlókna szklanego, posiada w jednym koncu nakladke pierscieniowa o ksztlacie stozka 5, zabezpbczona przed 5 zsunieciem z ciegna, sworzniem poprzecznym 6. W dru¬ gim koncu ciegna 1, umieszczone sa poprzeczne sworz¬ nie 4. Na nakladke pierscieniowa o ksztalcie stozka 5 na¬ lozona jest podkladka 3. Na przeciwleglym koncu, do kon¬ ca ze sworzniami poprzecznymi, znajduje sie wyciecie 15 poprzeczne 7.As can be seen from FIG. 1, a mining bolt according to the invention The cable consists of a rod in the form of a rod 1, preferably a fiber on the glass, which has a bead at one end no, 2, with an advantageous shape over which a support is placed tab 3. On the other end of the cord 1, there are half diagonal pins 4. End opposite to end with the transverse pins 43 there is a cutout transverse 7. 105 172 105 172 3 A different solution of the mining anchor was visualized 2 shows an anchor consisting of a tie rod and binders, the rod in the form of a rod 1, preferably Fiberglass with a cover at one end ring cone-shaped 5, protected against 5 sliding off the cable, transverse pin 6. Second At the end of the tie 1, transverse bolts are placed no 4. 5 on the cone-shaped ring overlay there is a washer 3. At the opposite end, to the end ca with cross bolts, there is a cutout 15 transverse 7.
