Definitions
- Support device for the suspension of a roll broom on a sweeping vehicle
- the present invention relates to a support device for the suspension of a roll broom on a sweeping vehicle, comprising a rotary support rotatably mounted on the sweeping vehicle about a vertical pivot axis, a supporting part suspended from the rotary beam via a lifting device comprising a lifting drive and one on the support part a horizontal broom frame, which is mounted so as to oscillate transversely to the axis of rotation of the roll broom.
- Such carrying devices are known from practice be ⁇ . Sweepers in which the roller brushes are suspended by means of corresponding carrying devices are used, for example, within the framework of the so-called black clearance at airports, in which the most complete removal of snow from traffic areas occurs.
- the pendulum-type suspension of the roller broom compensates for local variations in the lateral inclination of the surface to be cleaned and, on the other hand, lateral tilting of the sweeping vehicle when cornering.
- the pendulum position of the broom frame is pretensioned by means of suitable spring elements (eg rubber springs or gas pressure springs) into a zero position.
- roller brush grinds on one side during transport.
- the roller brush without such leveling of the brush unit would also grind unilaterally during acceleration and deceleration of the sweeping vehicle.
- US 2004/0040103 A1 discloses a carrying device for the suspension of a roll broom on a sweeping vehicle, which differs from the gat ⁇ ment forming prior art presented in the introduction in that here Hubeinrich ⁇ device is not provided a lifting drive. In the absence of a possibility to lift the support member, the above-mentioned problem is not present here.
- the US 4643261 A is a support device for Auf ⁇ suspension of a roll broom on a sweeper ent ⁇ removable, which differs from the introductory, generic state of the art characterized in that here the broom frame on the support member is not a horizontal Axially extending transversely to the axis of rotation of Wal ⁇ zenbesens axis is mounted pendulum. In the absence of such commutability, the problem addressed above in connection with generic carrying devices is also not present here.
- a locking member is provided in a supporting device of gat ⁇ type according to the art of pendulum storage of the broom frame, a first, the pendulum movement of the brush frame releasing and a second, the pendulum movement of the broom frame in the level position can assume blocking position and on which the lifting drive of the lifting device engages der ⁇ shape that the locking member occupies its second position when activated linear actuator.
- a charac teristic viewpoint of the present invention is thus that the lifting drive of the lifting device engages the locking member and when activating the Huban ⁇ drive to raise the brush unit, the locking member is forcibly operated, namely this ers ⁇ th, pendulum movements of the broom frame enabling Position in his second, the pendulum movement at influence ⁇ lierter 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 is deactivated during the turn-up operation (eg by a hydraulic lifting cylinder connected in the floating position), so that the roller brush can follow the surface to be cleaned by means of vertical compensatory movements, then different sideways inclinations of the surface to be cleaned are readily possible and / or different lateral inclinations 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 inclination of the sweeping vehicle, in particular during cornering with increased speed of the Walzen ⁇ broom rests over its entire length with the same Aufla ⁇ on the surface to be cleaned.
- the locking member is parallel to the axis of rotation of the roller broom horrre ⁇ ckende axis pivoted, and more preferably on the broom frame.
- the point of application of the lifting drive and the articulated articulation of the locking member on the brush frame can be arranged in particular on different sides of the brush frame.
- Such a design is characterized by a particularly high functionality.
- the blocking member in its first position as part of a stop device limits the pendulum movement of the brush frame to a predetermined range. Because by such a double function the locking member of the invention Tragvor ⁇ device comes from 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 clamp having two cheeks, which surrounds the articulated connection between the supporting part and the brush frame.
- the support part adjacent to its articulated connection with the broom frame particularly preferably has a stop for each of the two cheeks of the clamp.
- the lifting device comprises a Lenkerparallelogramm. It is particularly favorable if the link parallelogram comprises two double links, wherein the pairs of links of the two double links in each case the support member and the rotary carrier between them aufneh ⁇ . Also, 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. However, a corresponding arrangement of the linear actuator between the rotary carrier and the support member is also advantageous if the Lenkerparallelogramm the Hubein ⁇ direction includes no double link.
- FIG. 2 shows in a detail view from behind the area of the pendulum suspension of the broom frame of the Trag ⁇ device of FIG. 1,
- Fig. 3 is a view from obliquely left-rear-top on the support device according to FIGS. 1 and 2 with raised broom unit and
- Fig. 4 is a view from obliquely left-front-bottom on the support device according to FIGS. 1 to 3 eben ⁇ if raised broom unit.
- 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 supporting part 5 and a broom frame 6.
- the rotary support 3 is rotatable about a vertical pivot axis 7 on the sweeping vehicle stored.
- the support member 5 is articulated via the lifting device 4 and lowered lowered.
- the lifting device comprises a Lenkerparallelo ⁇ gram 8 with an upper double link 9 and a Unte ⁇ ren double link 10
- 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 part 5 is the broom frame 6, which is designed as Vier ⁇ square tube and on which the roll brush 2 in such a known manner about its longitudinal axis L ro- stored tierbar, suspended.
- the suspension follows er ⁇ a pendulum bearing 14 in the form of a pivot joint 15, which connects the broom frame 6 with the support member 5 about the horizontal, transversely to the axis of rotation L of the roll broom 2 extending axis IS pen ⁇ delbar.
- a locking member 17 in the form of a clamp 18 is provided which comprises two cheeks 19 and 20, two connecting pieces 21 and 22 connecting them to one another and two bracing 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 Ku ⁇ gelkopf - is hinged to the rotary support 3.
- the clamp 18 is pivotably mounted on the broom frame 6 by means of the two bearing lugs 27 welded to the broom frame 6 about the axis 28 extending parallel to the axis of rotation L of the roll broom 2. As a result, it can assume a lowered first position which releases the pendulum movement of the broom frame 6 and a raised second position which levels the broom frame and locks the pendulum movement of the leveled broom frame. In the second position of the clamp 18, which is raised by the activated lifting cylinder 25, cams 29 of the cheeks 19 and 20 rest against the underside of a stop plate 30, which forms part of the supporting part 5.
- the pendulum movement of the brush frame 6 is locked in its drivinglier ⁇ ter position; at the beginning of lifting the broom
- the clip 18 is brought from its first position to its second position while the broom unit is leveled.
- the clamp 18 can assume its lowered first position when the hydraulic cylinder is switched to its floating position, in which the brush unit can follow unevenness in the floor and / or different deflections of the sweeping vehicle by corresponding up and down movements of the support part ,
- the broom unit can freely and without any bias perform pendulum movements about the pivot axis 16 within a given angular range.
- 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 brush frame 6, wherein between the cheeks 19, 20 and the upper side of the brush frame 6 a slight, enabling the lower buffer elements 32 to be inserted Game exists; between the cams 29 of the cheeks 19 and 20 and the stop plate 30 is - in theani ⁇ lated position of the broom unit - both sides a game.
- the broom unit If the broom unit is deflected out of its level position, then, for a given pendulum angle, that of the two upper buffer elements 31 located on the lifting side of the broom unit contacts the underside of the stop plate 30 and dampens the bumps further oscillating movement, if necessary, upon further compression of the upper buffer element 31 the side of this associated cam 29 abuts the Anschlag ⁇ plate.
- the two lower Pufferelemen ⁇ te 32 are compressed in this case, if necessary. So far, until the lower edges of the cheeks 19 and 20 rest on top of the broom frame 6.
- the bracket 18 in its first position also forms part of a pendulum movement of the broom frame 6 limiting the stop device.
- the broom unit suspended from the illustrated supporting device can not only execute pendulum movements around the pivot axis 16 unhindered. Even bumps following up and down movements of the broom unit are compared with the prior Tech ⁇ nik, within a predetermined range of fluctuation easier.
