Definitions

  • the invention relates to a broom arrangement on a mobile wiper device according to the preamble of claim 1.
  • EP-A-0 467 269 shows a broom arrangement on a mobile wiper device in which a central broom on a boom can be pivoted about a pivot axis on the wiper device by means of a first drive and by means of a separate second drive and a parallelogram arrangement about a second pivot axis on the boom.
  • This arrangement has two separate drives with respective controls and is correspondingly complex, in particular also due to the parallelogram arrangement with its joints.
  • US-A-4 754 521 also shows a mobile wiper with a central sweeper. This can be moved parallel to the front of the wiper device by a first drive and pivoted about an axis of rotation by a separate second drive. Here too, a corresponding effort is required for two drives and their control.
  • EP-A-0 087 936 shows a swivel drive for a wiping brush which can only be swiveled about a swivel axis
  • WO 91/19052 likewise shows such a broom arrangement, in which an articulated axis is additionally provided as an overload protection.
  • the invention has for its object to provide such a broom arrangement, which can be constructed as simply and inexpensively. Furthermore, the arrangement of the brooms should be able to be brought into different working positions as continuously as possible.
  • the broom arrangement can be produced simply and inexpensively.
  • the fact that the one drive can adjust the broom with respect to the boom both in the direction of travel and transversely thereto results in great flexibility of use, which will be explained in more detail below.
  • the broom is held resiliently in order to go into an evasive position independently of the drive when it encounters an obstacle. In this way, there is a simple protection against damage when the broom hits an obstacle without the need for sensors and drives.
  • FIGS 1 and 2 show a broom arrangement 10 with a circular broom 1, which is attached to a wiper 11, not shown.
  • the wiping device 11 can be, for example, a municipal vehicle or also a self-propelled electric vehicle that can be controlled by an accompanying operator; all possible known embodiments for the mobile wiper device 11 are conceivable here.
  • the broom arrangement 10 is fastened to this wiper device 11 by means of a holding plate 5, the type of fastening not being shown in detail in the figures.
  • the attachment can be done for example by screws or by clamping or in another known way.
  • the plate brush 1 is fastened to the holding plate 5 by means of an arm 2 and a bracket 8.
  • the present invention relates to the adjustment of the working position of the broom. So that this working position can be adjusted, in the example shown, a boom 8 pivotally mounted on the holding plate 5 is provided, which on its end opposite the pivot axis bears an in turn pivotable arm 2, on the end of the disc brush 1 with its drive 9 opposite the pivot axis is attached.
  • a hydraulic drive 7 is provided which, on the one hand, is fixedly attached to the holding plate 5 is and on the other hand engages with its actuating part on the boom 8 outside the pivot axis.
  • the hydraulic drive 7 can consist of its known hydraulic piston / cylinder arrangement, for example the cylinder is attached to the holding plate 5 and the piston acts on the boom 8 via a rod in order to pivot it depending on the piston position.
  • a compressed air drive or an electric drive 7 can of course also be provided.
  • a chain wheel 3a is shown, which lies in the axis of rotation of the arm 2 and is connected to it, so that rotation of the chain wheel causes a corresponding pivoting of the arm 2.
  • This rotation of the sprocket 3a causes a rotation of the shaft of the sprocket and thus a corresponding pivoting of the arm 2 fastened to the shaft.
  • the resulting effect is due to different positions of the plate broom 1 or the boom and the arm shown.
  • the translation is chosen such that in the middle position of the arm 8 there is a parallel position of the arm 2, as can be seen, for example, in FIG.
  • the arm 2 is pivoted out again into the left working position shown in FIG. 4 (viewed from the wiping device) with the boom 8 pivoted fully to the left.
  • the translation preferably takes place in this way that the center of the plate broom 1 moves on a straight line 18 when the boom 8 is pivoted, as can be seen in FIG. 3.
  • the swiveling movement can also take place in such a way that the center of the plate broom moves on a non-straight path.
  • the choice of the translation and the path is made by choosing the sizes A, B, C and the diameter of the sprocket 3a (Fig. 2).
  • FIG. 5 shows a further preferred aspect of the invention.
  • the spring arrangement of the broom ensures that it can automatically avoid an obstacle. In the exemplary embodiment explained so far, this is achieved by the springs 6 and 6a.
  • FIG. 5 it can be seen how the plate broom 1 has avoided an obstacle 13 when it hits it. Evasion is made possible in that the arm 2 can be pivoted independently of the pivoting movement of the arm 8 by a force acting on the broom. With this pivoting of the arm 2, the sprocket 3a is rotated accordingly. The chain 4 allows this rotation due to the springs 6 and 6a.
  • FIG. 5 shows how the chain movement forced by the evasive movement of the broom 1 leads to the extension of the spring 6 or to the relief and contraction of the spring 6a. As soon as no external force acts on the plate broom, the force balance between the stretched and the contracted spring leads back to pivoting the arm 2 into its normal working position determined by the pivoting angle of the arm 8.
  • the plate broom is guided in such a way that there is no shift in the working direction when the broom is moved transversely, or the setting in the direction of travel is carried out during the swiveling movement so that the broom remains in a straight line despite the swiveling.
  • the displacement is also effected by a single drive element, which enables considerable cost savings and simplification of the arrangement.
  • the work of the sweeping broom is guaranteed in every position and the position changes are infinitely variable. In particular, wiping in corners is also possible in this way, as can be seen in FIG. 4.
  • collision protection against obstacles is achieved purely mechanically by the suspension of the broom. There are therefore no sources of error due to the provision of sensors and electronics, which in turn serves to save costs and operational security.
