Definitions

  • the present invention relates to a support device for the suspension of a roll broom on a sweeping vehicle, comprising a on the sweeper about a vertical pivot axis rotatably mounted rotary carrier, a suspended on the rotary carrier via a lifting drive comprehensive lifting device suspended support member and one on the support member to a horizontal Floating broom frame mounted transversely to the axis of rotation of the roll broom.
  • Such support devices are known in practice. Sweepers in which the roller brushes are suspended by means of appropriate support devices, for example, in the context of the so-called. Black clearance at airports used, in which it depends on the most complete removal of snow from traffic areas.
  • the pendulum suspension of the roll broom compensated on the one hand local variations in the lateral inclination of the surface to be cleaned and on the other hand, a lateral inclination of the sweeping vehicle, for example when cornering.
  • the pendulum position of the broom frame is biased by means of suitable spring elements (eg rubber springs or gas springs) into a zero position.
  • a similar support device is from the EP-A-296 563 known.
  • leveling is important because an otherwise common one-sided snow load in practice (in particular due to deposited on the broom cover snow dust) leads to that The roller brush grinds on one side during transport.
  • the roller brush without such leveling of the sweeping unit would also grind unilaterally during acceleration and deceleration of the sweeping vehicle.
  • the US 2004/0040103 A1 discloses a support device for the suspension of a roll broom on a sweeping vehicle, which differs from the introductory set forth generic prior art in that no stroke device comprising a lifting drive is provided here. In the absence of a possibility to raise the support member, the above-mentioned problem is not present here.
  • the US-A-2978720 shows a support device for the suspension of a roll broom with hydraulic cylinders for tilting the broom frame.
  • a locking member is provided in a support device of the generic type in the area of the pendulum bearing of the broom frame, the first, the pendulum movement of the broom frame releasing and a second, the pendulum movement of the broom frame in its level position blocking position can take and on which the lifting drive of the lifting device engages such that the locking member occupies its second position when activated lifting drive.
  • a characteristic aspect of the present invention is thus that the lifting drive of the lifting device acts on the locking member and upon activation of the lifting drive to lift the broom unit, the locking member is forcibly actuated, namely this from its first, oscillating broom frame enabling position in its second, the Pendulum movement in level position of the broom frame locking position brings. On the way from its first to its second position, the locking member brings the broom frame in its leveled position.
  • the lifting drive deactivated during the sweeping operation (eg by a hydraulic lifting cylinder connected in floating position) so that the roller brushes can follow by vertical compensating movements of the surface to be cleaned, so are also different side slopes of the surface to be cleaned and / or different side slopes of the Sweeper compensating pendulum movements of the roll broom possible.
  • the broom unit can swing freely and without any bias in the floating position determined by the first position of the locking member. In this way it is achieved that even with a substantial lateral tilt of the sweeping vehicle rests in particular during cornering with increased speed of the roller brushes over its entire length with the same bearing force on the surface to be cleaned.
  • the locking member is pivotally mounted about an axis parallel to the axis of rotation of the roll broom extending axis, and although particularly preferred on the broom frame.
  • the point of application of the lifting drive and the articulated linkage of the locking member may be arranged on the broom frame, in particular on different sides of the broom frame.
  • Such a design is characterized by a particularly high functionality.
  • the locking member limited in its first position as part of a stop means the pendulum movement of the brush frame to a predetermined range. Because by such a double function the locking member comes from the support device according to the invention with a minimum of components. In particular, in this case, it is particularly advantageous if shock-absorbing buffer elements are arranged on the blocking member, which effect at least towards the end of the permissible pendulum motion.
  • the locking member is designed as a pair of cheeks having bracket which engages around the hinge connection between the support member and the brush frame.
  • the support member adjacent to its articulated connection with the broom frame in each case a stop for each of the two cheeks of the clip.
  • the lifting device comprises a Lenkerparallelogramm.
  • the link parallelogram comprises two double links, the pairs of handlebars of the two double links each receive the support member and the rotary carrier between them.
  • the lifting drive can be arranged in this case between the pairs of handlebars of the two double link, whereby he is accommodated particularly protected.
  • a corresponding arrangement of the lifting drive between the rotary carrier and the support member is also advantageous if the Lenkerparallelogramm the lifting device does not include double link.
  • the support device 1 shown in the drawing for the suspension of a roll broom 2 on a sweeping vehicle comprises a rotary support 3, a lifting device 4, a support member 5 and a broom frame 6.
  • the rotary support 3 is rotatably mounted on the sweeper about a vertical pivot axis 7.
  • the lifting device comprises a Lenkerparallelogramm 8 with an upper double link 9 and a lower double link 10.
  • the pivotally connected in a known manner with the rotary carrier 3 and the support member 5 link pairs each of the two double links 9 and 10 take the support member 5 and the rotary support 3 between them on.
  • the two links 11 of the lower double link 10 are connected by means of two connecting pieces 12 and 13 rigidly together.
  • the broom frame 6 On the support member 5 is the broom frame 6, which is designed as a square tube and on which the roller brush 2 rotatable in such a known manner about its longitudinal axis L. is stored, suspended.
  • the suspension takes place via a pendulum bearing 14 in the form of a pivot joint 15 which connects the broom frame 6 with the support member 5 to the horizontal, transversely to the axis of rotation L of the roll broom 2 extending axis 16 pendulum.
  • a locking member 17 in the form of a clamp 18 is provided, which comprises two cheeks 19 and 20, two interconnecting connecting pieces 21 and 22 and two stiffening plates 23 and 24.
  • the bracket 18 engages around the pivot joint 15 by the two cheeks 19 and 20 are arranged on different sides of the pivot joint.
  • At the front connector 21 engages - via a ball head - a lifting cylinder 25, which forms the lifting device 4 associated lifting drive 26 and the other, upper end - again via a ball - is hinged to the rotary support 3.
  • the bracket 18 is pivotally mounted by means of the two welded to the brush frame 6 bearing plates 27 on the broom frame 6 about the parallel to the axis of rotation L of the roll broom 2 extending axis 28. It can thereby take a lowered first, the pendulum movement of the broom frame 6 releasing position and a raised second, the broom frame leveling and blocking the pendulum movement of the level broom frame blocking position.
  • the pendulum movement of the brush frame 6 is locked in its level position; at the beginning of lifting the broom unit
  • the clip 18 is brought from its first position to its second position, thereby leveling the broom unit.
  • Your lowered first position the bracket 18, in contrast, occupy when the hydraulic cylinder is switched to its floating position in which the broom unit uneven ground bumps and / or different compression of the sweeper can follow by appropriate up and down movements of the support member.
  • the bracket 18 In this first position of the bracket 18, the broom unit within a predetermined angular range unhindered and without any bias perform pendulum movements about the pivot axis 16.
  • two buffer elements 31 and 32 designed as rubber bumps are provided on both cheeks 19 and 20 of the clip 18, which are attached to a corresponding carrier 33 at the top and bottom. If the clamp 18 assumes its first position, then the two lower buffer elements 32 rest on top of the broom frame 6, wherein between the cheeks 19, 20 and the top of the broom frame 6 a slight, a compression of the lower buffer elements 32 enabling game exists; between the cams 29 of the cheeks 19 and 20 and the stop plate 30 is - in the level position of the broom unit - both sides a game.
  • the bracket 18 in its first position also forms part of a pendulum movement of the broom frame 6 limiting stop device.
  • the broom unit suspended from the illustrated carrying device can not only freely perform pendulum movements about the pivot axis 16. Even bumps following up and down movements of the brush unit are compared with the prior art, within a predetermined range of fluctuation easier. Because not every evasive movement of the broom unit in the vertical direction leads to a change in length of the lifting cylinder 25 and thus to a the rapid evasion obstructing displacement of hydraulic fluid; Rather, by the play of the cheeks 19 and 20 of the bracket 18 between the stop plate 30 on the one hand and the broom frame 6 on the other hand, the broom frame together with the support member 5 within a predetermined fluctuation range to perform movements in the vertical direction, without causing a change in the length of the lifting cylinder 25th leads. This is particularly favorable for an excellent cleaning result on surfaces with relatively short flat bumps.
