Description

Predmetom vynálezu je reťazové pila na dřevo, poháňaná elektrickou, hydraulickou alebo vzduchovou banskou ručnou vrtačkou, na ktorú sa podía potřeby nasunie ako přídavné snimatelné zariadenie s moŽnosťou vytvorenia rčznych polčh režného ramena.The object of the invention is a wood saw, driven by an electric, hydraulic or air mining hand drill, to which it can be slid as an additional detachable device with the possibility of creating different cutting arm positions.

Banskú vřtačkovú pilu podía tohto vynálezu možno úspěšně použiť pri budovaní a vystužovaní banských chodleb drevom, ako aj pri ich opravě a rekonštrukcii, pri budovaní protipožlamých hrádzí, pri likvidáoii banských požiarov, atá.The mining drill saw according to the present invention can be used successfully in the construction and reinforcement of mining tunnels with wood, as well as in their repair and reconstruction, in the construction of anti-dam dams, in the liquidation of mining fires, etc.

Dodnes takáto pila v uholných baniach s nebezpečím výbuchu plynov nie je známa a známe elektrická a benzinové pily v týohto baniach nemožno použiť z bezpečnostných dčvodov, preto sa tieto práce robia zdíhavým spósobom ručně. Pokial boli robené pokusy s vývojem RINGO pily, skončili s neúspechom, pretože táto pila bola počas činnosti nestabilná a životu nebezpečná a naviac představovala len nepohodlné, jednoúčelové zariadenie.To date, such a mine saw with a risk of gas explosion is not known and the known electric and petrol saws in these mines cannot be used for safety reasons, therefore this work is done in a hasty way by hand. When attempting to develop a RINGO saw, they ended in failure because the saw was unstable and life-threatening during operation and, moreover, was only an inconvenient, dedicated device.

Tieto nedostatky odstraňuje banská vrtačková pila podía vynálezu, ktorá je opatřená spojovacím medzikusom so zaisťovacími skrutkami, hnacím hriadelom, kuželovým prevodom a hnaným hriadelom, jej režné rameno je otočné okolo hnaného hriadela, okolo hnacieho hriadela a v požadovaných polohách sa dá zaistiť skrutkami a po použití je z banskéj vrtačky snímatelné.These drawbacks are overcome by a mining drill saw according to the invention, which is provided with a connecting piece with locking screws, a drive shaft, a bevel gear and a driven shaft, its cutting arm is rotatable about the driven shaft, around the drive shaft and removable from drilling machine.

Na obr. 1 je znázorněný bočný pohlad na pilu, na obr. 2 je znázorněný pčdoryený rez pily a pohladom a v spojeni s banskou elektrickou vrtačkou.In FIG. 1 is a side view of the saw; FIG. 2 is an enlarged cross-sectional view of the saw and view and in connection with a mining electric drill.

Banské vrtačková pila sa skládá z oedzikusa 2 ^ao skrutkami £, 2» ^v ktorom je otočné uložená ložisková teleso 6, pevne spojená s převodovou skriňou 11. v ktorej sú uložené kuželové kolesá 2, 8 a hnacím hriadelom 2 a s hnaným hrladelom 2· okolo ktorého osi 19 je výkyvné uložené režné rameno 15 so skrutkou 12. Režné rameno 15 je opatřené pilovou retazou 16. poháněnou retazovým kolesom 18. naklinovaaým na hriadeli 2·The mining drilling machine comprises an oedzik 2 ^and screws 6, 2 ' ⁱⁿ which the rotatably mounted bearing body 6 is fixedly connected to the gearbox 11 in which the bevel gears 2, 8 and the drive shaft 2 and with the driven shaft 2 are mounted. The cutting arm 15 is provided with a saw chain 16 driven by a chain wheel 18 pivoted on the shaft 2.

Počas činnosti sa banská vrtačková pila nasadí medzikusom 2 ^na banskú vrtačku 2 tak, aby hnací hriadel 2 zapadol do hrladela banskéj vrtačky 1 a v tejto polohe sa zaistí skrutkou £. Režné rameno 15 sa vykloní podlá potřeby v rozsahu uhlovot^, eCg a zaistí skrutkou 12 a naviac sa eáte ložiskovým telesom 6 natočí v medzlkuse 2 ^a zaletí skrutkou 2·During operation, the mining drill saw is fitted with a spacer 2 ^{on the} mining drill 2 so that the drive shaft 2 engages the shaft of the mining drill 1 and is secured in this position by the screw 6. The cutting arm 15 is tilted as desired within the range of the angles,, eCg and secured with the screw 12 and, in addition, the bearing body 6 is rotated in the intermediate piece 2 ^and inserted with the screw 2.

Po spustení banskej vrtačky sa otáča aj hnací hriadel 2 a pomocou kuželových kolies 2, aj hnaný hriadel 2 ^{a 8 a}í refazové koleso 18, ktoré poháňa pílovú retaz 16, ktorá řeže dřevo. Po skončení činnostisa odletí skrutka £, pila sa medzikusom 2 etiahne z banskej vrtačky 1, ktorá sa 3alej móže používat už ako vrtačka.After starting the mining drill, both the drive shaft 2 and the beveled wheels 2 and the driven shafts 2 ^{and 8 and the} impeller 18, which drives the saw chain 16, which cuts the wood, are rotated. Upon completion of the operation, the screw 6 flies off, the saw is pulled out of the intermediate drill 2 from the mining drill 1, which can then be used as a drill.

Výhodou tohto vynálezu je, že banskú vrtačkovú pilu možno v tomto převedení používat . aj vo výbušných baniach, pretože je poháňaná bezpečnostně schválenou banskou vrtačkou, ktorá sa takto stává viaoúčelovým zariadením a režné rameno pily možno postavit počas činnosti do takých poldh, ako to stiesnené podmienky v bani potrebujú.An advantage of the present invention is that a mining drill saw can be used in this embodiment. even in explosive mines, since it is powered by a safety-approved mining drill, which thus becomes a multi-purpose device and the saw arm can be placed in the poles during operation as the cramped mine conditions require.
