Definitions

  • the present invention relates to a mobile surface processing device, in particular for processing floor surfaces in buildings with two motor-driven rotor cages, which are arranged on a horizontal rotor shaft and on the cage bars of which a large number of abrasive impact processing elements are lined up.
  • a particularly simple and space-saving angular gear in the form of a bevel gear can also be used. If a polygonal, common drive shaft is used, a positive connection that is insensitive to vibrations can be produced between the shaft and the two rotors, which can also be easily replaced.
  • a preferred embodiment is shown in the drawing, for example, and is explained on the basis of the following description.
  • the chassis 1 is a welded sheet metal construction, which serves as a housing for the rotor cages shown in dashed lines in FIG. 1, and in which the transmission is also accommodated.
  • a bracket 2 attached to it carries the rigid axle 3 on which the two wheels 4 are mounted.
  • the abbreviated bumper 5 is also screwed to the bracket 2.
  • the bumper 5 ends in two handles 6 running at right angles to one another.
  • a switch box 7 for the on / off switch of the motor 8 is attached in the upper region of the bumper 5.
  • the motor 8 is connected to the chassis 1 and the transmission housing via a flange 9.
  • a capacitor is attached to the side of the motor 8 and cannot be seen in the drawing, which allows the single-phase AC motor 8 to be operated via the household power supply which is usually available in every building.
  • the chassis 1, which is designed as a self-supporting housing, is laterally covered with removable covers 10.
  • the covers 10 are held on the chassis 1 by means of front buckles 11. This allows good access to the rotors, the processing elements of which are subject to wear and therefore have to be replaced from time to time.
  • the connection between the chassis 1, the motor 8 and the transmission housing 20 can be seen from FIG. 3.
  • the shaft 12 of the motor 8 protrudes into the gear housing 20.
  • a bevel gear 21 with a hollow shaft 22 is seated on the shaft 12.
  • the hollow shaft 22 is rotatably supported by means of bearings 23 in the gear housing 20, but these bearings 23 serve mainly to transmit pressure from the gear housing 20 to the Motor housing and on the chassis 1.
  • the bevel gear 21 meshes with a second bevel gear 24 with a hollow shaft 25, which is seated on a two-part, polygonal, here hexagonal rotor shaft 30.
  • a two-part, polygonal, here hexagonal rotor shaft 30 On the left half of the rotor shaft 30, an outer cylindrical sleeve 26 is welded with a shoulder.
  • both shaft parts 30 are axially and radially supported and secured. This guarantees that the rotor shaft 30 passes through the transmission housing 20 symmetrically in its entirety.
  • a rotor cage 31 is pushed onto the rotor shaft 30 on both sides.
  • the rotor cages 31 each consist of a hollow axis 33, with two spaced disks 34 fastened thereon, in which the cage bars 35 are held.
  • the disks 34 are secured in the axial direction by rings 36 screwed on from the outside. Processing elements 37 are lined up on the cage bars 35 in a relatively loose pack, two of which are shown purely for example in broken lines.
  • the machining elements 37 which sit on the cage bars with considerable radial play, transmit both the side disks 34 of the drum and the protective plate 38, which protects the gear housing 20 and the lower edge of the self-supporting chassis 1.
  • the entire weight of the device lies on the rotor cages 31 or on the processing elements 37, while the wheels 4 do not or hardly touch the ground. If you drive the rotor cages 31 in the counterclockwise direction, the device moves forward slowly by itself. By strong pressure on the handles 6 of the handlebar 5, the device is tilted and is fully supported on the wheels 4.
  • the device according to the invention ideally combines the advantages of the hand-held devices and the road surface processing devices, namely the mobility and handiness of the former with the high weight machining power of the large machines. Furthermore, the device according to the invention enables the operator to stand upright, which also does not need to be in the dust zone.
  • the central arrangement of the gear unit allows the floor to be worked on in areas close to the wall.

4. Dispositif selon la revendication 3, caractérisé en ce que sur l'arbre du moteur (12) et sur l'arbre de rotor (30) des cages à rotors est monté, à chaque fois fixe en rotation, un pignon conique (21, 24) à tige creuse, de telle sorte que l'axe du moteur (12) soit perpendiculaire à l'arbre de rotor (30) et que le poids du moteur influe sur l'intensité de traitement.
5. Dispositif pour le traitement de surfaces selon la revendication 3, caractérisé en ce que l'arbre de rotor (30) présente des parties terminales polygonales et que les deux cages à rotors comportent chacune un axe creux (25) adapté à l'arbre de rotor polygonal et sont encagées de manière amovible sur l'arbre d'entraînement.
6. Dispositif pour le traitement de surfaces selon l'une des revendications 1 ou 3, caractérisé en ce que le châssis (1) est relié au carter d'engrenages (20), recouvre les deux cages à rotors et est pourvu de chapeaux latéraux amovibles (10).
