Definitions

  • Snow plow for mounting on the front of a carrier vehicle, on the support plate of which a snow plow-side device plate is fastened, which is connected via a frame part to the ploughshare in such a way that it can be raised and lowered relative to the device plate by means of a lifting and swiveling drive , and can be pivoted to both sides.
  • the tension occurring during the lifting or lowering process in the hydraulic cylinders and in the articulation elements is avoided by a control valve, which responds depending on the pressure build-up in the lifting cylinder and, as a result, briefly relieves the pressure on the swivel cylinders.
  • a relief process can be repeated several times during a lifting / lowering movement; it runs automatically and allows the swivel cylinders to be adapted to the respective lifting height without the swivel cylinders being depressurized.
  • the invention has for its object to avoid the undesirable blocking of the lifting movement by the pressurized swivel cylinder and the associated high loads on the hydraulic drive connections and the mechanical suspension of the ploughshare by creating a simple drive and movement system.
  • This object is achieved in that the frame part is guided in a vertical guide provided on the device plate, the lifting drive between the frame part and device plate, the swivel drive between the frame part and ploughshare is supported.
  • the invention makes use of the consideration that by eliminating a mutual influence of the lifting / lowering movement on the one hand and the swiveling movement on the other hand, any type of movement can be realized without restriction. Thanks to the frame part, which can be raised and lowered in a vertical guide, any required lifting height is possible; because the swivel drive sits on the frame part, there is no need to coordinate the drives for the different types of movement on each other. This applies to everyone drive type, also for hydraulic drives. By separating the two types of movement, pressure fluctuations in the hydraulic system caused by the mere movement are avoided. In this way, the loads acting on the frame part itself can be calculated, with the result that deformations due to overstressing are ruled out if the construction is correctly designed.
  • the frame part has guide strips running on both sides in a vertical plane, which are guided in associated guide rails attached to the device plate. This results in a sufficient leadership length for controllable managers.
  • the guide strips are designed to bulge out to the side.
  • the frame part can rotate to a limited extent about a horizontal axis running in the longitudinal direction of the vehicle in accordance with the crowning of the guide strips.
  • An advantageous embodiment of the frame part is characterized in the subclaims 6 to 8.
  • laterally projecting stops are provided on the frame part to limit the right-left swivel position of the ploughshare; the stops can be provided with buffers made of rubber-like material at their free ends.
  • the designer is free to choose the suitable type of drive.
  • the drive is proven by means of a hydraulic swivel cylinder and a hydraulic lifting cylinder, the former being articulated between the frame part and ploughshare, the latter being articulated between the frame part and implement plate, in accordance with the invention.
  • motor drives for example electric drives, which control the respective movement sequence via gear elements are also possible.

  • the representation acc. Fig. 1 shows a top view of the back of the ploughshare 1, which is composed in the horizontal direction of several share segments, of which only the middle share segment 2 is shown completely.
  • the ploughshare 1 is movably suspended on a rigid plow frame 5 via handlebar connections 3 and tension springs 4.
  • the plow frame 5 is in turn pivotally attached to vertical pins 6 at the front corner of a rigid frame part 7.
  • the frame part 7 is composed of an upper triangular frame 8, a lower triangular frame 9 (FIG. 2) and further vertical and horizontal frame parts. 2, the front corners of the two triangular frames 8, 9 are connected to one another by a vertical web 10, to which a vertical plate 11 is fastened.
  • the plate 11 carries tabs 12 with vertical, mutually aligned bores, in each of them a pin 6 is rotatably received.
  • the pins 6 are attached to the inside of an upper and a lower hollow profile 13, which form the plow frame 5 in conjunction with vertical struts, not shown.

  • the left guide rail 32 serves to receive the left guide bar 16 of the frame part 7; the right guide rail 33 is shown cut away, so that one can see the spherical design of the right guide bar 17 guided therein.
  • the left guide bar 16 is correspondingly spherical, so that the entire frame part 7 within the guide rails 32, 33 can be pivoted to a limited extent in both directions of rotation about an axis perpendicular to the plane of the drawing sheet.
  • the fact that the guide rails 32, 33 have inwardly bent legs 35, 36 at their upper end results in a corresponding limitation of the vertical lifting movement of the frame part 7, with the support beams 24, 25 which extend the frame part 7 upwards from the inside against the inwardly bent legs 35, 36 of the two guide rails 32, 33.
  • the device plate 34 has on its side facing the front 37 of the vehicle two hook-shaped lugs 38, which engage in corresponding pockets 39 on the side of the vehicle-facing support plate 40 centering from above, so that the devices plate 34 and the support plate 40 lie flat against each other.
  • the lifting cylinder 27 is arranged approximately vertically and at a distance from the device plate 34. To bridge the distance, two bearing plates 41 are provided on the underside of the device plate 34; the upper link plate 28 of the piston 42 of the lifting cylinder 27 is articulated between corresponding bearing plates 43 which are fastened to the crossbeam 26 of the frame part 7. Accordingly, an extension of the lifting cylinder causes the frame part 7 to be raised, while a shortening of the lifting cylinder results in a lowering movement of the frame part 7.

Abstract

Le chasse-neige est conçu pour un montage frontal sur un véhicule pourvu d'une plaque d'appui (40) à laquelle est fixée la plaque de base (34) du chasse-neige. La lame (1) est reliée à la plaque de base (34) au moyen d'organes de commande aptes à donner à la lame un mouvement d'élévation et d'abaissement par rapport à la plaque de base (34) ainsi qu'un mouvement de pivotement sur les deux côtés. Pour éviter un arrêt non désiré du mouvement d'élévation par les cylindres (20, 21) de commande du pivotement, le cadre (7) est guidé verticalement par rapport à la plaque de base (34), le dispositif de commande de l'élévation est supporté entre le cadre (7) et la plaque de base (34), le dispositif de commande du pivotement est placé entre le cadre (7) et la lame (1).
