PAKSUUSMITTAUSLAITETHICKNESS MEASURING DEVICE
Keksinnon kohteena on paksuusmittauslaite tiemerkintojen paksuuksien mittaamiseksi.The invention relates to a thickness measuring device for measuring the thicknesses of road markings.
5 Nykyåån erilaisten tiemerkintojen paksuuden mittaus kenttaolosuhteissa tapahtuu pååasiassa vain silmåmååraisesti. Minkåånlaisia kenttaolosuhteissa kaytettMviM laitteita ei ole. Varsinaiset tarkemmat mittaukset on tahån saakka suoritettu vain laboratorio-10 olosuhteissa ja tiemerkintojen paksuutta niitå teihin tehtSessS ei ole pystytty tarkkaan mittaamaan. Samoin merkintdjen kulumisen seuranta on ollut epamSSrSista kunnollisten mittauslaitteiden puuttuessa.5 Today, the measurement of the thickness of various road markings in field conditions is mainly done only visually. There are no such devices used in field conditions. Until now, the actual more accurate measurements have only been performed in laboratory-10 conditions, and it has not been possible to accurately measure the thickness of the road markings on them. Similarly, the wear of the markings has been monitored in the absence of proper measuring equipment.
Keksinnon tarkoituksena on poistaa edella 15 mainitut epakohdat. Erityisesti keksinnon tarkoituksena on luoda uudenlainen tiemerkintojen paksuuden mittaus-laite, jonka avulla erilaisten tiemerkintojen paksuus tien pinnassa voidaan nopeasti ja helposti mitata joko niiden valmistuksen yhteydessa tai myohemmin merkintS-20 jen kulumista seurattaessa.The object of the invention is to eliminate the above-mentioned drawbacks. In particular, the object of the invention is to provide a new type of device for measuring the thickness of road markings, by means of which the thickness of various road markings on the road surface can be measured quickly and easily either during their manufacture or later when monitoring the wear of markings.
Keksinnolle tunnusomaisten seikkojen osalta viitataan vaatimusosaan.With regard to the features characteristic of the invention, reference is made to the claims.
Keksinto kohdistuu paksuusmittauslaitteeseen tiemerkintojen, kuten tien pinnassa olevan keskiviivan, 25 sulkuviivan, reunaviivan, ryhmitysmerkin, suojatiemer-kinnan tai vast., paksuuden mittaamiseksi. Keksinnon mukaisesti laitteeseen kuuluu tukirunko, joka tukeutuu ainakin kolmella tukipisteellå tien pintaan mitattavan tiemerkinnån ulkopuolella tukipisteiden muodostaessa 30 ensimmåisen tason; mittarunko, joka tukeutuu ainakin kolmella mittapisteellå mitattavan tiemerkinnån pintaan mittapisteiden muodostaessa toisen tason, tukirungon ja mittarungon ollessa toistensa suhteen vapaasti pys-tysuunnassa liikkuvia; tukirungon ja mittarungon vSli-35 nen mittausjårjestely, jossa on tukipisteiden ja mittapisteiden vålisten alueiden yhteisessa keskipisteesså anturi tukirungon ja mittarungon vålisten pystysuun- 2 taisten siirtymien mittaamiseksi eli ensimmåisen ja toisen tason valisen etaisyyden måarittåmiseksi; seka vålineet mittaustulosten esittamiseksi.The invention relates to a thickness measuring device for measuring the thickness of road markings, such as a center line on a road surface, a closing line, an edge line, a grouping mark, a protective road marking or the like. According to the invention, the device comprises a support frame which rests on at least three support points on the road surface outside the road marking to be measured, the support points forming a first level 30; a measuring frame resting on the surface of the road marking to be measured at at least three measuring points, the measuring points forming a second plane, the support frame and the measuring frame being freely vertically movable relative to each other; a measuring arrangement vSli-35 of the support frame and the measuring frame, having a sensor at the common center of the areas between the support points and the measuring points for measuring the vertical displacements between the support frame and the measuring frame, i.e. for determining the distance between the first and second planes; as well as means for presenting the measurement results.
Keksinnon mukainen paksuusmittauslaite perus-5 tuu siihen, etta kolme pistetta måaråavSt eksaktisti tason, jolloin kolme tukipistettå tien pinnalla tai sopivasti jårjestettynå pinnan låheisyyteen tiemerkin-nån ulkopuolella måarittåvåt toisen tason ja kolme mittapistettå tiemerkinnan pinnalla måarittavat toisen 10 tason, joiden tasojen vålinen etåisyys mitataan tuki-rungon ja mittarungon vålisellå mittausjarjestelyllS.The thickness measuring device according to the invention is based on the fact that three points determine exactly the plane, whereby three second points on the road surface or suitably arranged in the vicinity of the surface outside the road marking are measured on the second level and three measuring points on the surface of the road marking with the measuring arrangement between the frame and the measuring frameS.
Edullisesti seka tukipisteinå etta mittapis-teinå kaytetåan pydria, jolloin laitetta voidaan siir-taå mitattavaa tien pintaa pitkin.Preferably, a pyrid is used as both a fulcrum and a measuring point, whereby the device can be moved along the road surface to be measured.
15 Edullisesti mittauslaitteeseen kuuluu kolme tukipistettM suuremmalla etaisyydellS toisistaan ja naiden valisså suppeammalla alueella kolme mittapis-tetta. Nain mittapisteiden ollessa suhteellisen låhellå toisiaan, laitteella voidaan mitata suhteellisen kapei-20 takin tiemerkintbjS, esim. keski- ja sulkuviivoja.Preferably, the measuring device comprises three support points at a greater distance from each other and, in the narrower range between them, three measuring points. Thus, when the measuring points are relatively close to each other, the device can measure the road markings of the relatively narrow jacket, e.g., the center and closing lines.
Edullisesti paksuusmittauslaitteessa tukirunko ja mittarunko eivåt ole sidottuja jaykSsti toisiinsa, vaan ainoastaan kytkettyjH toisiinsa niin, etta ne yhdessa liikkuvat osittain vierekkMin, sisakkain tai 25 påållekkain niin, etta ne vapaasti paasevat liikkumaan pystysuunnassa toistensa suhteen.Preferably, in the thickness measuring device, the support body and the measuring body are not rigidly connected to each other, but only connected to each other so that together they move partially side by side, nested or superimposed so as to be free to move vertically with respect to each other.
Keksinndn etuna tunnettuun tekniikkaan verrat-tuna on, ettS laitteella voidaan luotettavasti mitata tien pintaan tehtyjen erilaisten maalausten ja merkin-30 tojen paksuus seka heti niitå valmistettaessa etta myohemmin seurattaessa merkintojen kestavyyttS ja kulu-mista. Nain merkintojen tasaisuus ja tyon laatu voidaan varmistaa vMlittomåsti, mikå aiemmin tunnetuilla vali-neillå ei ole ollut mahdollista.An advantage of the invention compared to the prior art is that the device can reliably measure the thickness of various paintings and markings made on the road surface, both as soon as they are made and later when monitoring the durability and wear of the markings. In this way, the evenness of the markings and the quality of the work can be ensured immediately, which has not been possible with previously known options.
35 Muut keksinnon edut ja lisasovellukset kayvåt selville seuraavasta selityksestS, jossa viitataan oheiseen piirustukseen, jossa 90917 3 kuva 1 esittåå periaatteellista kuvaa keksinnon mukai-sesta paksuusmittauslaitteesta pååltå katsottuna ja kuva 2 esittåå sivukuvaa kuvan 1 laitteesta.Other advantages and further applications of the invention will become apparent from the following description, with reference to the accompanying drawing, in which 90917 3 Fig. 1 shows a schematic top view of a thickness measuring device according to the invention and Fig. 2 shows a side view of the device of Fig. 1.
Piirustuksen esittåmåån erååseen keksinnon 5 mukaiseen paksuusmittauslaitteeseen kuuluu jåykkå suo-rakaiteen muotoinen tukirunko 1, jonka påisså olevien poikkitankojen 10 paihin on akseloitu tukipisteina 2 toimivat pyoråt. Toinen poikkitanko on kiinnitetty tukirunkoon nivelellå 13, joka sallii poikkitangon 10 kååntymisen laitteen liikesuunnan 12 suuntaisen akselin ympåri. Nåin todellisuudessa tukipisteitå on kolme: jaykån poikkitangon paisså olevat kaksi pyoraa seka nivelpiste 13.One of the thickness measuring devices according to the invention shown in the drawing comprises a rigid rectangular support frame 1, the ends of the cross bars 10 at the ends of which are axled by wheels acting as support points 2. The second crossbar is attached to the support frame by a joint 13 which allows the crossbar 10 to pivot about an axis parallel to the direction of movement 12 of the device. Thus, in reality, there are three fulcrum points: the two wheels on the rigid crossbar and the articulation point 13.
Tukirunkoon 1 on sen mukana liikkuvaksi orren 15 11 avulla kiinnitetty mittarunko 3, jonka toiseen påå- hån on akseloitu kaksi pyoraa mittapisteiksi 4 ja toiseen påMhMn yksi pyorå kolmanneksi mittapisteeksi 4.A measuring frame 3 is fastened to the support frame 1 by means of a rod 15 11, on one end of which two wheels are axed as measuring points 4 and on the other end one wheel is mounted as a third measuring point 4.
Orsi tukee tukirungon ja mittarungon toisiinsa laitteen kulkusuunnassa jaykasti eli mahdollistaa laitteen sekå 20 vetåmisen etta tyontamisen, mutta sallii tukirungon ja mittarungon muun suuntaiset vapaat liikkeet toistensa suhteen.Orsi rigidly supports the support frame and the measuring frame in the direction of travel of the device, i.e. allows both the device 20 to be pulled and pushed, but allows the free movement of the support frame and the measuring frame in other directions relative to each other.
Nain pydrien ollessa tien pintaa vasten kolme tukipistetta måarittavåt yhden tason ja mittapisteet 4 25 eli naiden pyorien tien pintaa vasten olevat kohdat måarittavåt toisen tason.Thus, when the wheels are against the road surface, the three support points are determined by one level and the measuring points 4 25, i.e. the points of the wheels against the road surface, are determined by the second level.
Tukirunkoa 1 ja mittarunkoa 3 ei ole lukittu tai muuten kiinnitetty toisiinsa, vaan orsi 11 ainoas-taan pitåå ne samassa asennossa tasojen suunnassa lai-30 tetta eteenpåin eli nuolen 12 suunnassa tai taaksepåin liikutettaessa. Tukirunko 1 ja mittarunko 3 ovat mit-tauskontaktissa toisiinsa mittausjårjestelyllå 5, johon kuuluu sopiva anturi 6, esim. kelassa oleva rautasydån, jolloin tukipisteiden ja mittapisteiden måårittåmien 35 tasojen vålinen Hike saadaan halutulla tarkkuudella mitatuksi.Support body 1 and the measuring body 3 is not locked or otherwise secured to each other, but crossarm 11, the exclusive purpose of pitåå the same position in the direction of levels of lai-30 IFY forward, i.e. in the direction of arrow 12 or backward moved. The support frame 1 and the measuring frame 3 are in measuring contact with each other by a measuring arrangement 5 comprising a suitable sensor 6, e.g. an iron core on a coil, whereby the Hike between the support points and the levels 35 measured by the measuring points is measured with the desired accuracy.
Lisåksi mittauslaitteeseen on jårjestetty 4 ohjausjarjestely 7, yhdestå tukirungon 1 pyoråstå oh-jauksen ottava kytkin, jolla tarkkaillaan mittauslait-teen liikkeitå ja nain suoritettavat mittaukset voidaan ottaa sopivin mååråtyin vålein, jolloin mittaustulokset 5 saadaan esim. jatkuvana mitattavaa pintaa kuvaavana kåyrånå.In addition, the measuring device is provided with 4 control arrangements 7, a switch which takes control from one of the wheels of the support frame 1, by which the movements of the measuring device are monitored and the measurements can be taken at suitable intervals.
Tukirungon 1 ja mittarungon 3 vålistå pys-tysuuntaista liikettå mittaamaan sovitettu mittausjår-jestely 5 on sijoitettu sekå tukirungon etta mittarun-10 gon keskipisteeseen. Toisin sanoen anturin 6 paikka tukirungossa 1 on nivelen 13 ja kahden pyorån muodosta-man tasasivuisen kolmion keskipisteesså ja sen paikka mittarungossa 3 on kolmen mittapisteen 4 muodostaman tasasivuisen kolmion keskipisteessa.The measuring arrangement 5 adapted to measure the vertical movement between the support frame 1 and the measuring frame 3 is located at the center of both the support frame and the measuring frame 10. That is, the position of the sensor 6 in the support body 1 is at the center of the equilateral triangle formed by the joint 13 and the two wheels, and its position in the measuring body 3 is at the center of the equilateral triangle formed by the three measuring points 4.
15 Keksinnon mukaista paksuusmittauslaitetta kaytetåan seuraavasti. Laite asetetaan mitattavalle tien pinnalle niin, etta tukipisteet 2 muodostavat pyorat ovat puhtaalla tien pinnalla ja paksuudeltaan tutkittava tiemerkintå jåå niiden våliin. Tållåin mit-20 tapisteet 4 tukeutuvat mitattavaa tiemerkintaå vasten ja nain tukipisteet 2 maårittavat kasittelemåtontå tien pintaa kuvaavan tason ja mittapisteet 4 maårittavat tiemerkinnån 9 pintaa kuvaavan tason. Tålloin, kun mit-tausjårjestely 5 on sopivasti kalibroitu niin, ettå 25 tasojen ollessa kohdakkain anturi nåyttåå nollaa, saadaan tasojen vålinen etåisyys mååritetyksi ja nåin mittapisteiden 4 alla olevan tiemerkinnån paksuus re-kisterdidyksi.The thickness measuring device according to the invention is used as follows. The device is placed on the road surface to be measured so that the wheels forming the support points 2 are on a clean road surface and the thickness of the road marking to be examined remains between them. In this case, the mit-20 pins 4 rest against the road marking to be measured and thus the support points 2 define a plane representing the surface of the untreated road and the measuring points 4 define a plane representing the surface of the road marking 9. Then, when the measuring arrangement 5 is suitably calibrated so that when the 25 planes are aligned, the sensor shows zero, the distance between the planes is determined and thus the thickness of the road marking below the measuring points 4 is registered.
Edellå keksintoå on selostettu esimerkinomai-30 sesti oheisen piirustuksen avulla keksinnon eri sovel-lusten ollessa kuitenkin mahdollisia patenttivaatimus-ten rajaaman keksinnollisen ajatuksen puitteissa.The foregoing invention has been described, by way of example, with reference to the accompanying drawings, however, various embodiments of the invention are possible within the scope of the inventive idea defined by the claims.
