Description

Transportni voz z magnetnimi kolesiMagnetic wheeled transport cart

Izum se nanaša na transportni voz z magnetnimi kolesi, ki se z magnetnimi silami prilepi in drži na kovinski ploskvi.The invention relates to a transport cart with magnetic wheels, which is attached and held to the metal surface by magnetic forces.

Iz patentnega spisa DE 43 13 732 C2 je znan pogon z magnetnimi kolesi. Zadevni pogon obsega v ta namen po površini, konkretno tirnici, kotaleče se kolo, v katerem je po obodu razporejen niz elektromagnetov, ki so usmerjeni k tekalni površini kolesa. Magneti, ki so razporejeni neposredno v pogonskem kolesu, ustvarjajo vrtilni moment in oprijemalno silo. Pri ustreznem kotu glede na tirnico namreč povzroči magnetna sila vrtilno gibanje kolesa.DE 43 13 732 C2 discloses magnetic wheel drive. The drive in question comprises, for this purpose, a surface, in particular a rail, a rolling wheel in which a series of electromagnets are arranged around the circumference, directed towards the running surface of the wheel. Magnets arranged directly in the drive wheel generate torque and grip force. Namely, at a given angle with respect to the rail, the magnetic force causes the wheel to rotate.

Pri opisani znani rešitvi je niz magnetov razporejen v kolesu tako, da je med njimi in tirnico vedno določena razdalja; magneti torej ne nalegajo neposredno na tirnico. Pomanjkljivost tega je, da je za zagotovitev potrebnega vrtilnega momenta potrebna sorazmerno velika magnetna sila oz. so potrebni sorazmerno veliki magneti, kajti z večanjem razdalje med magnetom in ploskvijo, na katero nalega kolo, magnetna sila močno upade. Na to razdaljo vplivajo tudi neravnine na površini, po kateri se kotali kolo z magneti, npr. zvari, korozijske neravnine, ipd. Za zagotovitev ustrezno velike magnetne sile pa so seveda potrebni ustrezno veliki in težki magneti.In the known solution described, the array of magnets is arranged in a wheel such that there is always a distance between them and the rail; therefore, the magnets do not rest directly on the rail. The disadvantage of this is that a relatively large magnetic force or a magnetic force is required to provide the required torque. relatively large magnets are required, because as the distance between the magnet and the surface on which the wheel rests increases, the magnetic force drops sharply. This distance is also affected by the irregularities on the surface along which the magnet wheel is rolling, e.g. welds, corrosion bumps, etc. Of course, large and heavy magnets are required to ensure a sufficiently large magnetic force.

Naloga izuma je torej ustvariti transportni voz z magnetnimi kolesi, kije ob ustrezno veliki magnetni sili prilepljenja na kovinsko ploskev sorazmerno lahek in se ga da voziti po poljubni navpični in celo previsni realni ploskvi.The object of the invention is therefore to create a transport cart with magnetic wheels which, with a suitably large magnetic force, adheres to the metal surface relatively easily and can be driven on any vertical and even overhanging real plane.

Zastavljena naloga je po izumu rešena s tem, da soosno z valjastim ohišjem poteka v njem uležajena gred, na katere vsakokratnem, iz ohišja štrlečem koncu je razporejeno tekalno kolo. Tekalni kolesi nalegata pri tem neposredno na kovinsko ploskev, ki mora seveda biti prevodnik magnetnega polja, npr. jeklen ladijski trup, po kateri naj bi se transportni voz gibal. V ohišju je prav tako soosno razporejeno električno navitje, ki obdaja omenjeno gred. Ohišju je nadalje prigrajena oporna noga, na katere prostem koncu je v nastavku uležajeno podporno kolo.The task according to the invention is solved by the fact that along with the cylindrical housing there is a shaft mounted thereon, on which the running wheel is arranged at each end projecting from the housing. The impellers are directly against the metal surface, which must of course be a magnetic field conductor, e.g. the steel hull through which the transport wagon is to move. The housing also has a coaxially arranged electrical winding that surrounds said shaft. The housing is further fitted with a support leg, with a support wheel resting on the free end of the housing.

Transportni voz po izumu je bodisi gnan s kakšno drugo, po sebi znano napravo, ali pa je zasnovan kot pogonski voz. V ta namen je na ohišju razporejen pogonski motor, obsegajoč vsaj en štrcelj motorske gredi, pri čemer je na omenjenem vsakokratnem štrclju razporejeno pogonsko kolo. Vrtilni moment se s pogonskega motorja prenaša na tekalni kolesi tako, da je pogonsko kolo v tomosklepni zvezi s tekalnim kolesom. Alternativno pa je pogonsko kolo zasnovano kot pastorek, ki ubira v zobati venec, razporejen na boku tekalnega kolesa.The transport cart according to the invention is either driven by some other known device or designed as a drive cart. For this purpose, a drive motor is arranged on the housing, comprising at least one crankshaft projection, and a drive wheel is arranged on said projection. The torque is transmitted from the drive motor to the drive wheel in such a way that the drive wheel is in this connection with the drive wheel. Alternatively, the drive wheel is designed to be a pinion that engages a toothed wheel arranged on the side of the treadmill.

Da se doseže čimboljše rezultate, so ležaja, gred in tekalni kolesi izdelani iz materiala, ki dobro prevaja magnetno polje. Temu nasprotno mora biti ohišje izdelano iz materiala, ki slabo prevaja magnetno polje.For best results, the bearings, the shaft and the wheels are made of a material that conducts well with the magnetic field. In contrast, the housing must be made of a material that conducts poorly on the magnetic field.

Izum je v nadaljevanju pobliže predstavljen na osnovi izvedbenega primera in s pomočjo skic, kjer kaže sl. 1 transportni voz z magnetnimi kolesi po izumu v pogledu s strani, sl. 2 transportni voz v prerezu po črti II-II s sl. 1.The invention will now be further described on the basis of an embodiment and with reference to the drawings, in which FIG. 1 is a side view of a conveyor with magnetic wheels according to the invention; 2 is a cross-sectional view of the transport cart along line II-II of FIG. 1.

Transportni voz z magnetnimi kolesi po izumu obsega valjasto ohišje 1, pri čemer sta v območju vsakokratnega prostega konca ohišja 1 razporejena ležaja 2, 2’. Skozi ohišje 1 in soosno z njim poteka gred 3, ki je vsakokrat uležajena v omenjenih ležajih 2, 2’ in štrli iz ohišja 1. Vsakokratnemu prostemu koncu gredi 3 je togo prigrajeno tekalno kolo 4, 4’, ki s svojo tekalno površino nalega na ploskev P, po kateri naj se transportni voz giblje. Pogoj pa je seveda, da je ploskev P dober prevodnik magnetnega polja, npr. jeklen ladijski trup.The conveyor with magnetic wheels according to the invention comprises a cylindrical housing 1, with bearings 2, 2 'arranged in the area of the respective free end of the housing 1. Through the housing 1 and coaxially therewith runs a shaft 3, which is in each case mounted in said bearings 2, 2 'and protrudes from the housing 1. Each free end of the shaft 3 is rigidly fitted with a running wheel 4, 4', which with its running surface rests on the plane P along which the transport car should move. However, the condition is, of course, that the plane P is a good conductor of the magnetic field, e.g. steel hull.

V ohišju 1 je soosno z njim in gredjo 3 razporejeno električno navitje 5, pri čemer je med slednjim in gredjo 3 vsakokrat na voljo ustrezno velika zračna rega. Električno navitje 5 je pri tem v bistvu popolnoma zaprto v ohišju 1, pri čemer ga po eni strani omejuje ostenje ohišja 1 in po drugi vsakokratni ležaj 2, 2’.In the housing 1, an electrical winding 5 is arranged coaxially with it and the shaft 3, and a correspondingly large air gap is available between the latter and the shaft 3. The electrical winding 5 is thus substantially completely enclosed in the housing 1, bounded on the one hand by the housing wall 1 and, on the other, by the respective bearing 2, 2 '.

Središčno glede na vzdolžni potek ohišja 1 je le-temu prigrajena pravokotno nanj stoječa podolgovata oporna noga 6, ki je na svojem prostem koncu in na strani, obrnjeni k ploskvi P, zasnovana z nastavkom 7, v katerem je uležajeno podporno kolo 8. Tudi podporno koloCentrally with respect to the longitudinal course of the housing 1, there is attached to it a rectangular longitudinal support leg 6, which, at its free end and on the side facing the surface P, is designed with a nozzle 7 in which the support wheel 8 is mounted. the wheel

8, tako kot vsakokratno tekalno kolo 4, 4’, nalega s svojo tekalno površino na ploskev P, po kateri naj se transportni voz giblje.8, just like the respective running wheel 4, 4 ', rests with its running surface on the surface P along which the conveyor is to move.

Nadaljnja izvedba transportnega voza po izumu predvideva, da je med tekalnima kolesoma 4, 4’ in prednostno na proč od ploskve P obrnjeni strani ohišja 1 razporejen pogonski motorA further embodiment of the transport cart according to the invention provides that a drive motor is arranged between the running wheels 4, 4 'and preferably away from the surface P facing the housing side 1

9, ki je na po sebi znan način lahko gnan bodisi z električno energijo, energijo stisnjenega zraka ali podobnim. Pogonski motor 9 obsega na svoji čelni strani neprikazan štrcelj motorske gredi, na katerem je razporejeno pogonsko kolo 10. Vrtilni moment se iz pogonskega motorja 9 prenaša na tekalno kolo 4’ preko pogonskega kolesa 10, katero je v danem primeru v tornosklepni zvezi s tekalnim kolesom 4’. Vrtilni moment pa se lahko na tekalno kolo prenaša tudi na drug znan način, npr. tako, daje pogonsko kolo 10 zasnovano kot pastorek, ki ubira v neprikazan zobati venec, pritrjen na boku tekalnega kolesa.9, which in a manner known per se may be driven by either electricity, compressed air or the like. The drive motor 9 comprises, on its front side, a non-exposed crankshaft projection on which the drive wheel 10 is arranged. The torque is transmitted from the drive motor 9 to the drive wheel 4 'via the drive wheel 10, which is optionally in contact with the drive wheel. 4 '. However, torque may also be transmitted to the impeller in another known manner, e.g. thus, the drive wheel 10 is designed as a pinion that engages in a non-visible gear ring attached to the side of the treadmill.

Prav tako lahko nadaljnja izvedba izuma obsega pogonski motor, na katerega obeh čelnih straneh sta na voljo strelja motorske gredi, na katerih je vsakokrat pritrjeno po eno pogonsko kolo. V tem primeru sta na voljo torej dve pogonski kolesi, ki sta sočasno v prijemu s tekalnima kolesoma.Further embodiments of the invention may comprise a drive motor on which both shafts are provided with firing shafts, each with one drive wheel attached at each end. In this case, therefore, two drive wheels are available which are simultaneously in the grips with the running wheels.

Nadalje je mogoča tudi izvedba, pri kateri sta ležaja 2, 2’ razporejena v tekalnih kolesih 4, 4’, pri čemer je gred 3 vrtilno togo razporejena v ohišju 1, vrtita pa se samo tekalni kolesi. Pri tej izvedbi se zahteva, da ležaja dobro prevajata magnetno polje.Further, an embodiment is also possible in which the bearings 2, 2 'are arranged in the running wheels 4, 4', the shaft 3 being rigidly arranged in the housing 1, and only the wheels are rotating. In this embodiment, the bearings are required to translate the magnetic field well.

Gred 3 in tekalni kolesi 4, 4’ so prednostno zasnovani iz materiala, ki dobro prevaja magnetno polje, ohišje pa temu nasprotno iz materiala, ki slabo prevaja magnetno polje.The shaft 3 and the rollers 4, 4 'are preferably designed from a material which conducts well the magnetic field, and the housing to the opposite from a material which conducts poorly through the magnetic field.

Transportni voz z magnetnimi kolesi po izumu se uporablja tako, da se ga postavi na pokončno kovinsko ploskev P, npr. jeklen ladijski trup, pri čemer je noga 6 obrnjena navzdol. Vklopimo napajanje električnega navitja 5, ki požene magnetni tok skozi gred 3 in tekalni kolesi 4, 4’ ter pokončno kovinsko ploskev P. Rezultat tega je, da magnetna sila prižame tekalni kolesi 4, 4’ ob ploskev P, s čimer drži transportni voz v danem položaju.The conveyor with magnetic wheels according to the invention is used by placing it on an upright metal surface P, e.g. steel hull with leg 6 facing down. We turn on the power supply of the electrical winding 5, which drives the magnetic flux through the shaft 3 and the impellers 4, 4 'and the upright metal face P. The result is that the magnetic force presses the impeller 4, 4' along the face P, thereby holding the transport cart in given position.

Nadalje vklopimo napajanje pogonskega motorja 9, če je transportni voz seveda tako zasnovan, pri čemer ga zagonski vrtilni moment želi zasukati okoli osi ohišja 1. Pri tem se vrtilni moment preko noge 6 prenese na podporno kolo 8, ki se nasloni na ploskev P. S tem se zagotovi stabilnost transportnega voza na ploskvi P, od pogonskega motorja 9 pa se vrtilni moment preko pogonskega kolesa 10 prenaša na tekalno kolo 4’. Tekalni kolesi 4, 10 4’ se zavrtita in pričneta premikati transportni voz po ploskvi P navzgor. Za premik transportnega voza v nasprotno smer se samo zamenja smer vrtenja pogonskega kolesa 10 oz. motorja 9.We further switch on the power supply to the drive motor 9 if the transport car is of course designed in such a way that the starting torque wants to rotate it about the axis of the housing 1. The torque is then transferred via the leg 6 to the support wheel 8, which rests on the surface P. S this ensures the stability of the transport carriage on the surface P, and from the drive motor 9, the torque is transmitted via the drive wheel 10 to the drive wheel 4 '. The rollers 4, 10 4 'rotate and start moving the transport carriage along the surface P upwards. To move the transport car in the opposite direction, only the direction of rotation of the drive wheel 10 or 8 is changed. engine 9.
