Description

1 Forfarande for dampning vid en borrmaskin samt en borrmaskin TEKNISKT OMRADE Foreliggande uppfinning avser ett forfarande f6r dampning vid en borrmaskin. Uppfinningen avser ocksa en borrmaskin innefattande ett arrangemang for dampning samt ett fordon som är utrustat med borrmaskinen. 10 BAKGRUND Borrmaskiner anvands idag for borrning av hal i berg. Dessa hal kan vara avsedda for sprangning eller bergforstarkande atgarder, sasom exempelvis bultsattning. Sagda borrmaskiner är vanligtvis monterade pa matararmar hos en borrigg. En borrigg kan innefatta ett antal matararmar som är forsedda med en respektive borrmaskin anordnad pa en hydrauliskt eller pneumatiskt driven matarslade. Sagda borrigg är ofta operatorsstyrd. TECHNICAL FIELD The present invention relates to a process for steaming to a drilling machine. The invention also relates to a drilling machine comprising an arrangement for steaming and a vehicle equipped with the drilling machine. 10 BACKGROUND Drilling machines are used today for drilling halls in rock. These slides can be intended for blasting or rock-strengthening measures, such as bolting. Said drilling machines are usually mounted on feed arms of a drilling rig. A drilling rig may comprise a number of feed arms which are provided with a respective drilling machine arranged on a hydraulically or pneumatically driven feed shaft. Said drilling rig is often operator-controlled.

Borrmaskiner av idag är ofta utrustade med en dampningskonfiguration som i viss man kan dampa returkrafter fran berget vid positionering och borrning. Today's drilling machines are often equipped with a steaming configuration which, to a certain extent, can steam return forces from the rock during positioning and drilling.

Harvid kan negativ paverkan av sagda borrmaskin reduceras och en tamligen tillforlitlig drift av borrmaskinen kan harvid astadkommas. Dessa returkrafter benamns aven bergreflexer och är elastiska vagor som loper fran en borrkrona hos borrstalet genom borrstalet via en nackadapter till 25 borrmaskinen dar de helt eller delvis dampas ut av sagda dampningskonfiguration. In this case, the negative impact of said drilling machine can be reduced and a fairly reliable operation of the drilling machine can be achieved. These return forces are also called rock reflectors and are elastic waves which run from a drill bit of the drill bit through the drill bit via a neck adapter to the drilling machine where they are completely or partially evaporated out of said steaming configuration.

Vid vissa situationer kan alltfOr hOga returkrafter fran berget uppsta. Detta kan exempelvis ske vid positionering av borrstalet mot berget. Harvid kan en ovan eller ofOrsiktig operator av fordonet medelst lampliga medel fOrflytta sagda borstal pa ett sadant satt att det stoter mot berget, varvid sagda alltfor h6ga returkrafter kan uppsta. F6r de fall dar sagda dampningskonfiguration 2 inte formar dampa ut sagda returkrafter fullstandigt stumtrycks denne, varvid negativ paverkan kan uppsta has borrmaskinen. Sagda negativa paverkan kan uttryckas i form av ett oonskat eller olampligt slitage. In some situations, excessive return forces from the rock can occur. This can be done, for example, when positioning the drill bit against the rock. In this case, an above or negligent operator of the vehicle can, by means of suitable means, move said brush strokes in such a way that it abuts the rock, whereby said excessive return forces can arise. In cases where said steaming configuration 2 does not form a steam, said return forces are completely silenced, whereby a negative effect can arise if the drilling machine is used. Said negative impact can be expressed in the form of unwanted or inappropriate wear.

AlItfor stora returkrafter kan aven uppsta vid borrning da en matningskraft for borrmaskinen mot berget är alltfor star. Borrstalet has borrmaskinen ska vid borrning ligga an mot berget med ett lampligt tryck for att astadkomma effektiv borrning. Harvid kan en ovan eller oforsiktig operator av fordonet nnedelst lannpliga nnedel, exennpelvis en slade uppbarande en borrmaskin anordnad vid en matararm, trycka sagda borrstal pa ett sadant satt att alltfor hoga returkrafter uppstar. Harvid kan drift av borrmaskinen paverkas negativt. Likasa kan sagda dampningskonfiguration stumtryckas da den inte formal- dampa ut sagda returkrafter fullstandigt, varvid negativ paverkan kan uppsta hos borrmaskinen. Sagda negativa paverkan kan uttryckas i form av oonskat slitage. Too large return forces can also occur during drilling as a feed force for the drilling machine against the rock is too strong. The drilling rig has the drilling machine must, when drilling, abut the rock with a suitable pressure to achieve efficient drilling. In this case, an above or careless operator of the vehicle, including a ground-breaking part, for example a sledge carrying a drilling machine arranged at a feed arm, can press said drilling numbers in such a way that excessive return forces arise. In this case, operation of the drilling machine can be adversely affected. Likewise, said steaming configuration can be silenced as it does not formally evaporate said return forces completely, whereby a negative impact can arise on the drilling machine. Said negative impact can be expressed in the form of unwanted wear.

AlItfor stora returkrafter kan aven uppsta vid borrning da borrstalet traffar pa en halighet i berget, varvid borrstalet kan matas genom halet och traffa berget pa nytt . Flarvid kan en antic& hog returkraft uppsta, varvid sagda 20 dampningskonfiguration kan stumtryckas da den inte formar dampa ut sagda returkrafter fullstandigt. Harvid kan negativ paverkan uppsta hos borrmaskinen. Sagda negativa paverkan kan uttryckas i form av oonskat slitage eller till och med metallbrott hos borrmaskinen. 25 AlItfor stora returkrafter kan aven uppsta da en operator framdriver fordonet pa ett sadant satt att borrstalet hos borrmaskinen traffar berget med en alltfor star kraft. Too large return forces can also occur when drilling when the drill bit hits a hole in the rock, whereby the drill bit can be fed through the tail and hit the rock again. In doing so, an antic & hog return force can arise, whereby said vaporization configuration can be silenced as it does not form vapor out said return forces completely. In this case, a negative impact can occur on the drilling machine. Said negative impact can be expressed in the form of unwanted wear or even metal breakage of the drill. Excessive return forces can also occur when an operator propels the vehicle in such a way that the drilling number of the drilling machine hits the rock with an excessively strong force.
