Description

Vynález sa týká zariadenia, ktorým možno střihat’ matice zahrdzavenýoh skrutiek ocelověj banskéj výstuže ohodieb a iných zariadení, ktoré možno potom 1’ahko rozobrať.The invention relates to a device which can be used to cut nuts of stainless steel mine steel bolts and other devices which can then be easily disassembled.

Dodnes známe střihače matic sú ťažké a zložité zariadenia, poháňané tlakovou kvapalinou alebo stlačeným vzduohom, v dósledku čoho je..ioh použitie v bani obmedzené alebo vóbeo nemožné.The prior art nut cutters are heavy and complex devices, driven by a pressurized liquid or compressed air, which makes the use of the mine limited or impossible.

Uvedené nedostatky odstraňuje univerzálny střihač matic podl’a tohto vynálezu, ktorého podstata spočívá v tom, že brity sú do matice tlačené dvomi dvojramennými pákami, výkyvné spojenými čapom, ktorých druhý koniec je ovládaný protiohodnou skrutkou pomooou páky s reverznou západkou a západkovým kolesom alebo hydrauliokým valcom.The above-mentioned drawbacks are eliminated by the universal nut cutter according to the invention, which consists in that the blades are pushed into the nut by two double-arm levers, pivotally connected by a pin, the other end being controlled by a counter-rotating bolt using a lever with reverse pawl and pawl or .

Výhodou univerzálneho strihača matic podl’a tohto vynálezu je, že ho možno ovládat’ ručně a použit’ aj tam, kde nie je tlaková alebo el. energie, je jednoduchý, výrobně nenáročný, l’ahko přenosný a pohotový.The advantage of the universal nut cutter according to the present invention is that it can be operated manually and used even where it is not pressurized or el. energy is simple, easy to manufacture, easy to carry and responsive.

Na obr. 1 je jeho bočný pohlad, na obr. 2 je pódorysný pohlad, na obr. 3 čelný pohlad a na obr. 4 je tento střihač ovládaný hydrauliokým valoom.In FIG. 1 is a side view thereof; FIG. 2 is a plan view, FIG. 3 is a front view and FIG. 4, this cutter is operated by a hydraulic valoom.

Univerzálny střihač matío sa skládá z dvoch dvojramennýoh pák 2., 24. výkyvné spojených čapom 6 a na ramenách 23 opatřených britmi 2., 22 otočnými na čapoch 4., 25The universal matio cutter consists of two double-arm levers 2., 24. pivotally connected by pin 6 and on arms 23 provided with blades 2., 22 pivotable on pins 4., 25

208 188 a v žiadanej polohe zaistenýoh poietkou £.208 188 and secured in the desired position by a screen 6.

Dlhjfí konleo pák £, 24 je opatřený vidlloami Í9. v ktorýoh sú matioe 11 otočné v čapooh 12, oez ktoré preohádza protlohodná ekrutka 13 so západkovým koleeom 14. do ktorého zapadá reverzná západka 18, tlačená do západkového kolesa 14 pružinou 17, ovládaná pákou 2 výkyvnou okolo oei protlohodnej skrutky 13.The longitudinal lever 48, 24 is provided with a fork 9. in which the mats 11 are rotatable in a pin 12, which is interspersed by a counter-rotating bolt 13 with a latch wheel 14. into which the reverse latch 18, pushed into the latch wheel 14 by a spring 17, is operated.

Počas činnosti sa brity 2, 22 od seba najprv vzdialia vratným pohybem páky £ a západky postavenej ták, aby ekrutka prlťahovala k sebe dlhčie ramená pák £, 24. Střihač ea potom založí na matlou £, ktorú třeba prestrihnúť, prestavníkom 15 sa rohatka přestaví do opačnéj polohy a vratným pohybom páky £ sa brity 2., 22 tlačia do matioe £ tak dlho, až ju prestrihnú. Zraneniu obsluhy přestřihnutou matioou, ktorej kusy od britov odlétla, zabránia kryty 20. 21. Po přestřihnutí matioe sa skrutkový spoj už l’ahko rozoberie a oelý proces sa už len opakuje. KeS je činnost’ skončená, páka 2 ea zatlačí medzi páky £, 24, střihač sa uohopí za rukováť Q a pohodlné ea neeie. V případe, že je na praoovieku tlaková kvapalina, pákový meohanizmus £, 14, 13. 11 sa nahradí hydrauliokým valoom 26 s ovládáčom 27. čím sa pracovný prooes urýohli a ul’ahčí.During operation, the blades 2, 22 first move away from each other by reciprocating the lever 6 and the latch of the built-in hook so that the ecru will pull the longer arms of the levers 24, 24 together. in the opposite position, and by reciprocating the lever 6, the blades 2, 22 are pressed into the matte 4 until they are cut. Injuries to the operator by cutting off the mat, the pieces of which have departed from the blades, will be prevented by covers 20. 21. After cutting the mat, the screw connection is easily disassembled and the process is repeated. When the operation is complete, the lever 2 e is pushed between the levers 24, 24, the cutter is grasped by the handle 6 and the comfortable e nee. If there is a pressurized liquid on the slurry, the lever meohanism 8, 14, 13, 11 is replaced by a hydraulic valoid 26 with an actuator 27. thus making the working process easier and easier.

Velkost’ strihaoej sily na britooh 2,, 22 závisí na pomere ramien a, Jb, ako aj na etúpaní protiohodnej skrutky 13 a na dížke páky £.The magnitude of the shear force on the britooh 2, 22 depends on the arm ratio a, Jb as well as on the splay of the counter-screw 13 and the length of the lever £.

Střihač matío možno využit’ k strihaniu zahrdzavenýoh matío skrutiek výetuže a inýoh zariadení, ako aj k strihaniu reťazí hřeblových dopravníkov, ooel’ovýoh tyčí a iného materiálu, a to tak v bani, ako aj na povrohu.The Matío cutter can be used to cut rust-proof mat screws of bolts and other equipment, as well as to cut chain conveyor chains, ooel bars and other material, both in the mine and on the surface.
