Abstract

A boring protector is applied to protect the operator of the boring machine and the room where this activity is taking place. The invention has a form of an accordion-like, axially compressible tube which is applied to the housing of the boring machine and compressed or released depending on the movement of the boring machine relatively to the groundwork. The compressibility of the tube is protected by the tightness obtained by the contact with the boring groundwork. Thus, the accumulation of drilled grains and dust within the protector is assured, and the operator of the boring machine and the room where the boring is taking place are protected.

Description

ŠČITNIK ZA VRTANJEROTATION SHIELD

Področje tehnike na katero ee Izum navezujeThe field of technology to which the invention relates

Predmet izuma spada v področje sredstev za zaščito pri ročnem delu z orodji za vrtanje, navezuje pa se na zaščito osebe, ki z orodjem upravlja ter zaščito prostora od zrnc peska in prahu, ki se med izvajanjem dela sproščajo v prostoru.The object of the invention is within the scope of hand protection tools with drilling tools, and relates to the protection of the person who manages the tool and the protection of the room from grains of sand and dust released during the work.

Tehnični problemA technical problem

Tehnični problem, ki se rešuje s to prijavo, se sestoji v sledečem:The technical problem to be solved with this application is the following:

• kako zaščititi osebo (posebej oči), ki rokuje z vrtalnim strojem, predvsem pri vrtanju v zidove in strope in kako zaščititi prostor (hrana, preproge, tapison, pohištvo, tekočine, antikvar, itd), v katerem se izvaja delo z vrtalnim strojem in se tako izogniti čiščenju in stroškom.• how to protect the person (especially the eyes) handling the drilling machine, especially when drilling into walls and ceilings and how to protect the space (food, carpets, upholstery, furniture, liquids, antiques, etc.) in which the drilling machine is operated and thus avoid cleaning and expense.

Med vrtanjem v armiranobetonske in druge zidane gradbene elemente in konstrukcije nastajajo in se sproščajo odpadna zrnca vrtanega materiala in prah. Posebej pri vrtanju navzgor (stropov) padajo zrnca ob svedru in udarjajo proti vpenjalni glavi vrtalnega stroja Ta jih z veliko hitrostjo razpršuje radialno na smer sile svedra in smer vrtanja vrtalne glave. Pri tem delu so najbolj ogrožene oči in pregled dela upravljalca vrtalnega stroja (četudi uporablja zaščitna očala), zrnca in prah pa se širijo po prostoru in ga onesnažujejo.During drilling into reinforced concrete and other masonry building elements and structures waste grains of drilled material and dust are generated and released. Particularly when drilling upwards (ceilings), the grains fall against the drill bit and strike against the drilling head of the drilling machine. At a high speed, they disperse them radially to the direction of the drill force and the direction of drilling of the drill head. This work is the most endangered eyes and inspection of the drilling machine operator's work (even if he is wearing safety glasses), and grains and dust are spreading around and polluting it.

Stanje tehnikeThe state of the art

Po avtorjevih spoznanjih je nekaj proizvajalcev vrtalnih strojev do sedaj ponujalo pripomoček podoben lončku, ki naj bi zbiral gravitirajoči izvrtani odpadni material, ki nastaja pri vrtanju navzgor. Droben prah in manjša količina slučajno odbitih grobih odpadnih delcev pa še naprej ostaja nevarnost in ovira za upravljalca vrtalnika in dejavnik onesnaženja prostora v katerem se vrtanje opravlja. Pri vodoravnem vrtanju v prej navedene materiale je poudarek na ohranjanju čistosti prostora in tuje, prej omenjeni »lonček«, praktično neuporaben.According to the author, several drilling machine manufacturers have so far offered a pot-like accessory designed to collect gravitationally drilled waste material from upstream drilling. Fine dust and a small amount of randomly deducted coarse waste particles remain a hazard and a barrier for the drill operator and the pollution factor in the drilling room. In horizontal drilling into the aforementioned materials, the emphasis on maintaining the cleanliness of the room and foreign, the aforementioned "crucible", is practically useless.

Predstavitev izumaPresentation of the invention

Osnovni cilj izuma je, da se kar najbolj zaščiti prostor v katerem se dela z vrtalnim strojem, kot tudi, da se zaščiti upravljalca vrtalnika pred zrnci peska in prahu, ki se sproščajo med vrtanjem.The primary object of the invention is to protect as far as possible the space in which the drilling machine is operated, as well as to protect the drill operator from the grains of sand and dust released during drilling.

Ščitnik je v bistvu zbiralnik vrtanine v obliki stisljive cevi, ki se na eni strani vpne na ohišje vrtalnega stroja, na drugi strani pa se naslanja na vrtano površino ( zid ali strop ). Cev, vpeta v vrtalnik, je v svojem razbremenjenem stanju nekoliko daljša od pritrjenega svedra, vpetega v glavo vrtalnega stroja. Prislonjena na vrtano površino se med delom stiska po svoji vzdolžni osi in s tesnjenjem na površino, zadržuje v svoji notranjosti izvrtana odpadna zrnca peska in prahu. Ko je izvrtana željena globina izvrtine, se vrtalni stroj s svedrom odmakne od vrtane površine, do tedaj stisnjena cev (predmet izuma) pa se raztegne in v sebi zadrži izvrtani material.The shield is basically a well collector in the form of a compressible pipe, which clamps on the one side of the drilling machine housing and rests on the drilled surface (wall or ceiling) on the other. The barrel clamped in the drill bit is slightly longer in its unloaded condition than the drill bit attached to the drill head. Pressed against the drilled surface, it is compressed along its longitudinal axis and sealed to the surface during the work, and the waste grains of sand and dust retained in its interior. When the desired depth of the hole is drilled, the drilling machine moves away from the drilled surface with the drill bit, and until then the compressed tube (the subject of the invention) is stretched and retains the drilled material.
