Definitions

  • the invention relates to an overhead headlamp sweeper according to the preamble of claim 1.
  • the pivot arms of the sweeping roller based on the frame of the machine slidably content Erten holding elements, which have an inclined support surface and which are displaceable by means of a Bowden cables containing actuating mechanism in the axial direction of the sweeper.
  • a Bowden cables containing actuating mechanism in the axial direction of the sweeper.
  • the holding elements are held by Bowden cables of the actuating device in a defined position, so that in the case of an unused sweeping roller, the support of the pivot arms of the sweeping roller are supported on the front and thus high end of the retaining surfaces of the retaining elements.
  • this rear position of the holding elements with respect to the frame of the sweeper is the holder of the dirt container in its caused by the support rods, the rearmost position.
  • the adjustment in this prior art overhead head sweeper fulfills the task of adjusting the longitudinal axis of the sweeping roller and the lower edge of the inlet opening of the dirt container when shortening the bristles in operation completely satisfactory.
  • it is composed of relatively many individual parts, and the longitudinal guides for the holding elements can be difficult due to the dusty ambient air.
  • an overhead headlamp sweeper of the type mentioned above is characterized according to the invention by the characteristics of the license plate.
  • the support of the pivot arms of the sweeping roller in the sweeping position causing cable is connected to an actuating mechanism, with which at least one support element for the dirt container is coupled. Therefore, if the adjusting mechanism for adjusting the position of the longitudinal axis of the sweeping roller actuated and thereby the effective length of the cable is increased, there is also a corresponding displacement of the support the dirt container, so that the lower carcass of the inlet opening of the dirt container is adjusted according to the changed position of the sweeping roller.
  • the cable is preferably a Bowden cable, the sleeve sections are arranged close to the movable support surface with respect to the rope.
  • the adjusting mechanism may comprise a rotatable, but axially non-supported mounted screw spindle, on which a non-rotatable relative to the machine frame adjusting nut sits, and the cable can be firmly connected to the adjusting nut, with a linkage for the displacement of a support member may be coupled.
  • the screw spindle is preferably arranged substantially perpendicular to the support plane, and it may have a handle element for manual rotation at one end. By turning the screw the adjusting nut is displaced along the screw and so changed the effective length of the cable connected to the adjusting nut.
  • Such a construction is sturdy and simple, and it allows for easy and accurate manual adjustment.
  • the at least one support element for supporting the dirt container may have a curved support surface and be pivotally supported on machine frame, and on the at least one support member may engage a push rod which is coupled via a pivot lever with the adjusting nut.
  • Upon rotation of the screw for adjusting the sweeping mirror of the sweeping roller then takes place via the pivot lever and the push rod pivoting of the at least one support element, so that another area of the curved support surface is effective.
  • the shape of the support surface can be adapted to the desired Nachstellverlauf the dirt container.
  • the at least one support member may be provided on a side portion of the machine frame, and another, with this rigidly coupled and a corresponding support surface exhibiting support member may be disposed on the opposite side region of the machine frame, so that the relatively heavy Dirt container is supported in its two outdoor areas.
  • the one end of the cable can be coupled to an actuating lever which, when actuated in one direction, the end of the cable so shifts so that the support surface is depressed and thereby the sweeping roller is raised to the position for travel operation.
  • FIG. 1 illustrated overhead head sweeper has in the usual way a frame 1, which carries the various components and units of the sweeper, which is movable on wheels, of which only the wheel 2 is shown.
  • the sweeper has an area 3 for the driver, wherein in this area a driver's seat and the usual controls are arranged.
  • In the front region of the sweeper is provided in the usual way not interesting for the present case, but usual side brush 5.
  • the sweeper has a conventional cylindrical sweeping roller 4, which is supported on not shown, coupled to each other via the axis 10 pivoting arms, so that a pivoting of the pivot arms pivoting of the other pivot arm in the same direction and to the same extent result, whereby the Longitudinal axis 4 'of the sweeping roller 4 is raised or lowered along a curved path.
  • the Figures 3 and 4 are also parts of the usual, not interesting here drive mechanism for rotating the sweeping roller 4 shown in the counterclockwise direction.
  • the dirt container 6 is connected to two arms 16, 17, which via an axis 19 (FIG. FIG. 1 ) are rigidly coupled together, held, and by activation of a working cylinder 18 (FIG. FIG. 3 ) are pivoted to a raised position, which allows the emptying.
  • the one of the sweeping roller 4-holding pivot arms in the form of a two-armed lever, and its longitudinal axis 4 'of the sweeping roller 4 facing away from arm 7 carries at its outer end a roller forming a bearing surface 11.
  • the part 20 extends a Bowden cable , whose sheath 21 is interrupted in this area and attached here at 21 "fixed to the frame or at 21 'fixed to the arm 7.
  • the Bowden cable or its rope 20 is firmly connected at the front end with a linkage arrangement, which is kept non-displaceable in sweeping.
  • the cable 20 of the Bowden cable runs over a guide roller 22 upwards, where the rear end of the rope 20 fixed to a control nut 27th connected is.
  • the adjusting nut 27 is seated on a screw spindle 26, which is arranged on a substantially perpendicular to a support plane formed by the support surface of the wheels of the sweeper extending and fixed to a frame 1 carrier 25 rotatable, but axially non-displaceable.
  • a handle member 26 ' is provided, which allows the rotation of the screw by hand.
  • the adjusting nut 27 has at its outer ends pin elements 28 which in perpendicular guide slots of the carrier 25 (FIG. FIG.
  • a U-shaped pivot lever 29 On a rotatably mounted in the carrier 25 axis 30 is a U-shaped pivot lever 29. The provided with slots 31 of the pivot lever is coupled to the adjusting nut 27. On the other end of the pivot lever 29 is a stub axle with a joint to which the push rod 34 is connected. This extends rearwardly and is coupled to an arm 35 which is fixedly connected to a support member 36. The support member 36 is connected via the axis 38 with a further support member 37 which is located in the region of the opposite side of the frame 1.
  • the support members 36 and 37 have curved support surfaces against which the dirt container 6 supporting arms 16 and 17 abut in sweeping, so that by the orientation of the support members 36 and 37 in cooperation with the shape of their support surface, the position of the dirt container 6 and in particular the position the lower edge 15 of the receiving opening of the dirt container with respect to the outer circumference of the sweeping roller 4 is fixed.
  • sweeping operation determines the effective length of the rope 20 by its engagement with the bearing surface formed by the roller 11, the pivotal position of the sweeping roller 4 supporting pivot arms and thus the so-called sweeping mirror, i. the area in which the free ends of the bristles of the sweeping roller 4 come into engagement with the floor to be cleaned.
  • the position of the front edge 15 with respect to the circumference of the sweeping roller 4 is determined by the screw shaft 26 and the push rod 34 connected to it via the adjusting nut 27 and the pivot lever 29 in cooperation with the shape of the support surfaces of the support elements 36 and 37, so that both an optimal dimension of the formed between broom 4 and tunnel wall 8 Ben tunnel as well as an optimal distance of the front edge 15 of the receiving opening of the dirt container 6 with respect to the outer periphery of the sweeping roller 4 results.
  • the front end of the cable 20 of the Bowden cable is connected to an eyelet 42 on a bolt 43 (FIG. FIGS. 7 and 8th ), which is part of the intermediate lever 41.
  • This intermediate lever is mounted on a frame 45 mounted on the frame 1, rod-shaped actuating element 40, which has at its upper end an angled grip portion which, as in FIG. 1 indicated, is directly accessible to the driver.
  • the driver rotates the angled to a handle portion actuator 40 counterclockwise ( FIG. 7 ), so attached to the intermediate lever 41 end of the cable 20 of the Bowden cable is displaced forward.
