Definitions

  • the present snow plow is especially adapted for attachment to the front end of a carrier vehicle.
  • a main blade and extension blade means attached to one or both lateral ends of the main blade.
  • Power means are provided for moving the extension blade means back and forth between an extended operating position and a retracted rest position or to any desired intermediate position.
  • the extension blade means comprise telescoping sections which are driven by a piston cylinder arrangement.
  • a power driven journal means is provided for tilting the extension blade means. The telescoping and tilting movements may be performed simultaneously.
  • auxiliary snow plows attached to the sides of the vehicle.
  • Such auxiliary snow plows are attached to one or both sides of the vehicle and are journaled approximately intermediate the ends of the vehicle for an inward and outward tilting of the auxiliary plow blades. This tilting movement is controllable by the operator from the operator cabin. This makes it difficult for the operator to visually monitor the positioning of the auxiliary plow blades.
  • a snow plow or an attachment snow plow in which the main blade is extended beyond the width of the vehicle on one or both lateral sides or ends of the main blade by lateral extension blade means whereby the movability of these extension blade means is accomplished by telescoping means and/or by journal hinge means.
  • journal hinge means may take up a vertical position or in an aternative embodiment it may be slightly inclined in a forward direction. This has the advantage that the swinging of the extension blade into its retracted position simultaneously lifts the outer end of the extension blade slightly upwardly whereby obstacles may be cleared.
  • the main blade may be extended by the length of the extension blade or by the length of two extension blades one of which is attached to each end of the main blade. If the road to be cleared is of normal width, the extension blade or blades are tilted into a rest position backwardly toward the vehicle. The extension blades are kept in this retracted position also when the vehicle moves along a road without the need of clearing it, for example, from a garage to a place where clearing is to be performed.
  • extension blade means comprise several sections
  • an end section overlaps with its rear surface the snow facing front surface of an intermediate section located between the main blade and the end section.
  • several sections of the extension blade means are connected to each other by telescoping means so that an end section will slide along the front face of an intermediate section when the end section is retracted.
  • FIG. 1 illustrates a top plan view of the front portion of the carrier vehicle having attached thereto a snow plow according to the invention
  • FIG. 2 is a top view similar to that of FIG. 1, however, on a slightly enlarged scale and omitting the vehicle as well as most of the main blade; only the left hand end of which is shown;
  • FIG. 3 shows a rear view onto the extension blade means as it would appear substantially from the vehicle and viewing in a forward direction;
  • FIG. 4 is a view similar to that of FIG. 3, however, illustrating the left hand end section of the extension blade means
  • FIG. 5 shows a side view of the end section according to FIG. 4 as viewed from its free end
  • FIG. 6 is a hydraulic circuit diagram for the actuation of the extension blade means according to the invention.
  • FIG. 1 illustrates a top plan view onto the carrier vehilce 1 to the front end of which there is attached a snow plow 2 by means of arms 3 and 4.
  • the position of these arms 3 and 4 is adjustable in a conventional manner for adjusting the elevational position of the snow plow 2.
  • one end of each arm 3 and 4 is hinged to a vertical axis 1 l.
  • the opposite end of the arms 3 and 4 is coupled to the front end of the vehicle by coupling means 5 and 6.
  • the snow plow 2 is tilted for removing the snow from left to right.
  • the latching means 7 to 10 may comprise secured bolts extending through respective holes in a conventional manner.
  • the vehicle 1 will advance in the direction indicated by the arrow F and the above mentioned directions of snow removal are to be understood with respect to such direction of vehicle advance.
  • the snow plow 2 comprises a center piece 12 to which is attached the main blade comprising several sections 13, 14, 15, 16, and 17.
  • extension blade means 18 are movably attached to the left hand end 23 of the main blade of the snow plow 2.
  • the extension blade means 18 are hinged to a journal axis 19.
  • extension blade means 18 The retracted or rest position of the extension blade means 18 is shown in FIG. 1 by dash-dotted lines.
  • the extension blade means 18 will also be kept in the retracted position where the length of the main blade is sufficient for accomplishing the desired clearing width.
  • extension blade means 18 may be attached to one end of the main blade as shown in FIG. 1 or to both of the main blade, or merely to the opposite end.
  • the extension blade means 18 comprise, for example, two blade sections 25 and 26.
  • the extension blade section .25 has a rear surface 20 and an outer end 21.
  • the extension blade section 26 has a rear surface 26' and forms an intermediate blade member.
  • the blade sections and 26 are movably connected to each other for a telescoping movement whereby the entire extension of the extension blade means may be reduced by the length B shown in FIG. 1. It has been found to be satisfactory toselect the telescoping length B so it corresponds approximately to the maximal height H of the segment of the circle K along which the outer tip 21 of the extension blade section 25 moves when the extension blade means are tilted about the axis 19.
  • the just mentioned segment and thus its height H is defined by a line extending in parallel to the forward direction of vehicle advance and through the tip 21 of the end section 25,-when the latter is in its fully extended position.
  • the retracting of the end section 25 simultaneously with the backward tilting of the extension blade means 18 as will be described in more detail below, has the advantage that the backward tilting may be accomplished even if the available space as defined by the circle K is not available. This may, for example, be the case where the road runs along adjacent to a wall or where a lane extends along a separating boundary wall.
  • the outer end 21 of the outer blade section 25 is preferably provided with a supporting means or element 22 such as a skid or a supporting roller schematically indicated at 22.
  • a supporting means or element 22 such as a skid or a supporting roller schematically indicated at 22.
  • Such a skid or roller will prevent that the outer end of the extension blade means becomes interlocked with a lateral obstacle.
  • an external force will be exerted on the extension blade means and such force may be employed to control automatically the withdrawal of the extension blade means.
  • the entire snow plow including the main blade and the extension blade means may be supported on the ground by means of wheels, preferably wheels provided with air tires. Such wheels are conventional and therefore not shown.
  • FIG. 2 illustrates the extension blade means 18 in a plan view of a somewhat larger scale as compared to FIG. 1.
  • the main blade of the snow plow 2 is provided with an adapting end portion 23 and the intermediate section 26 of the extension blade means 18 is held in such a position that it contacts the left hand edge of the portion 23 in a flush manner to form an abutting contact 24.
  • the extension blade means are shown in their fully extended position in which the rear surface 20 of the outer end extension section 25 overlaps the front surface of the intermediate blade section 25 to the extend L.
  • the extension blade means 18 are rigidly connected to a shaft 37 by means of a double arm rocker bracket 27 which will journal with its shaft 37 about the axis 19. In this manner the extension blade means are tiltable as described above with reference to FIG. 1.
  • the movable interconnection between the extension blade sections 25 and 26 is accomplished by a telescoping frame structure to be described below and by a piston cylinder arrangement 29 positioned for a substantially horizontal stroke.
  • the cylinder 30 is connected to the frame structure 47 of the intermediate blade section 25 by hinge means 31.
  • the piston rod 32 is connected to the frame structure 55 of the end section 25 by hinge means 33.
  • the dash-dotted lines in the lower right hand corner of FIG. 2 indicate the rest or re tracted position of the extension blade means 18.
  • journal means are provided for hinging the rocker bracket 27 for a tilting movement about the axis 19.
  • the journal means comprise a bearing drum 34 which is rigidly connected to the rear surface of the main blade.
  • Two drive motors, for example, rotary piston hydraulic drive motors 35 and 36 are supported in the bearing drum 34.
  • the drive motor 35 has an upwardly pointing stump 37 which is rigidly connected through a bushing 39 to an upper arm 41 of the rocker bracket 27.
  • the drive motor 36 has a downwardly extending shaft stump 38 connected through the bushing 40 to the lower arm 42 of the rocker bracket 27.
  • the shaft stumps or ends 37, 38 are rigidly connected to the bracket 27 so that rotation of the shafts 37, 38 about the axis 19 will journal the entire bracket 27.
  • the bracket 27 comprises in addition to the upper arm 41 and the lower arm 42 vertical connecting means including tubular members 43, 44, 45, and 46.
  • a horizontal tubular member 47 of the above mentioned frame structure is rigidly connected to the rocker bracket 27 between the vertical tubular members 44 and 45, for example, by respective weldments.
  • a further tubular member 48 of the frame strucutre is welded to the bracket between the tubular members 45 and 46.
  • the frame structure further comprises vertical ribs 49 and 50 secured to the rear surface 26 of the intermediate extension blade section 26.
  • the horizontal tubular members 47 and 48 are rigidly connected to these vertical ribs 49 and 50.
  • the vertical members 43 and 44 of the bracket 27 are releasably connected to each other by means of flanges 51 and 52 in order to facilitate the assemblyv
  • the end section 25 of the extension blade means 18 is similarly supported.
  • a frame structure comprising vertical ribs 53 and 54 and horizontal tubular members 55 and 56 support the end section 25.
  • the vertical ribs 53 and 54 are rigidly connected to the rear surface 20 of the end section 25.
  • the horizontal tubular members 55 and 56 are in turn rigidly connected to the vertical ribs 53 and 54.
  • the outer dimensions of the tubularmembers 55 and 56 are such that these members fit into the tubular members 47 and 48 of the frame structure secured to the intermediate blade section 26. Accordingly the two sections 25 and 26 may telescope relative to each other.
  • FIG. 4 illustrates a rear view of the end section 25 disconnected from the intermediate section 26.
  • This view shows still more clearly the connection of the vertical ribs 53 and 54 to the rear surface 20 of the blade section 25 and the connection of the tubular telescoping frame members 55 and 56 to the ribs 53 and 54.
  • I-Iollow sectional members 60 and 61 are welded in an abutting fashion to the rear surface 20 of the blade section 25. Further, these hollow sectional members 60 and 61 are welded to each other to form a T.
  • These sectional members 60 and 61 bear with their surface facing the viewer against the front surface of the intermediate blade section 26 whereby the length of overlap depends upon the instantaneous telescoped position of the two blade sections relative to each other. In any event, even in the fully extended position, the overlap 1.. shown in FIG. 2 will be maintained. Further, the overlap 1.. shown in FIG. 2 will be maintained. Further, the overlap 1.. shown in FIG. 2 will be maintained. Further, the overlap 1.. shown in FIG. 2 will be
  • blade section 25 is provided along its lower side with a clearing edge 63 gliding along the ground 62.
  • FIG. 5 shows a side view of the end section 25 with its clearing edge 63 and the carrier frame including the tubular members and 56 as well as the rib 53.
  • the rib 54 is not seen since it is located in back of rib 53.
  • the tubular members 55 and 56 are connected by a cross piece 64 which also may be of tubular cross section.
  • the hinge means 33 comprise two connecting pieces 65 and 66 welded to the cross piece 64.
  • the left hand end of the piston rod 32 is connected to these pieces 65 and 66.
  • the piston cylinder arrangement 29 is not seen in FIG. 5.
  • channel members 60 and 61 which preferably have a U-crosssectional shape not only act as guide means but also reinforce the extension blade 25 since these guide and reinforceing channel members 60 and 61 are welded to the rear surface 20 of the blade section 25.
  • the lower rear side of the blade section 25 is further forified by a channel member 67 having an extension 68.
  • the channel member and the extension are preferably welded to the lower edge of the blade section 25.
  • journal axis 19 is slightly inclined at an angle a in the forward direction F and relative to a plane P extending perpendicularly to the longitudinal extension of the snow plow blades.
  • This slightly forwardly inclined position of the journal axis 19 has the advantage that the outer end of the extension blade means 18 is raised when the extension blade means 18 are tilted backwardly whereby minor obstacles, for example, protruding man hole covers may be easily cleared.
  • This hydraulic system includes the rotary piston motors 35 and 36 as well as the pressure supply means connected thereto.
  • These pressure supply means include a safety valve 69 which may be adjustable to a selectable minimum response pressure, for example, about 120 bar. As soon as such preadjusted pressure is exceeded, the safety valve 69 opens the conduit 72 between the storage 70 and the oil sump 71. Corresponding to the rearward tilting of the extension blade means 18 in response to the movement of the vehicle against the obstacle, oil is displaced from the hydraulic motors 35 and 36 into the sump 71.
  • the pressure in the storage 70 which contains a gas bubble is increased due to the pressure increase in the conduit system.
  • the extension blade means 18 will yield only partially or completely until the rest position is reached as indicated by the dash-dotted lines in FIG. 1.
  • the extension blade means 18 will be yieldingly held in any intermediate position. In other words, the larger the external force in excess of a certain predetermined minimum force, the extension blade means will yield to that extent and will then be held in any intermediate tilted position by a hydraulic counter force so that damage to the equipment is avoided.
  • the extension blade means may have to be tilted backwardly to a larger extent or even completely.
  • the pressure build up in the storage 17 will maintain the extension blade means under a yielding counter force as described above.
  • the operator may return the extension blade means into their fully extended position by interrupting the conduit circuit 73 through the biasing valve 72. Whereas in the shown position of the conduit circuit 73 and the valve 72 the pump 74 may operate without pressure.
  • valve 72 In the interrupting position of the valve 72 hydraulic fluid is supplied through the conduit 75 and the pilot or control valve 76 to the conduit 77 and thus to the motors 35 and 36. It is assumed that the valve 76 is in its open position rather than in its shown neutral position. The just described supply of hydraulic fluid to the rotating piston motors 35 and 36 accomplishes the journaling of the rocker bracket 27 and thus the tilting of the extension blade means 18 in an outward direction.
  • the operator may also effect an intentional inward tilting.
  • the conduit 73 is again closed or interrupted by the valve 72 and the pilot or control valve 76 is moved into its closed position.
  • the pump 74 then removes hydraulic liquid from the drive motors 35 and 36 through the conduits 78 and 79 whereby the removed liquid is returned into the oil sump 71.
  • a pressure limiting device 80 which may be an adjustable valve similar to valve 69 is connected to the pump 74 and to the conduit 75 on the one hand to the sump 71 on the other hand. This pressure limiter 80 assures the safety of the system.
  • the telscoping of the extension blade sections 25 and 26 relative to each other is, as described above, controlled by the piston cylinder arrangement 29 also schematically shown in FIG. 6.
  • the pressure in cylinder 30 is maintained continuously through the conduit 81 so that the end section 25 will normally be kept in its fully extended position. If the end section 25 hits a lateral obstacle with its skid or roller 22, an external force is exerted-on the piston rod 32 and thus on the respective piston so that the latter will be moved to the right whereby the pressure in the, system is increased.
  • the hydraulic fluid which is displaced by the rightward movement of the piston 32 in the cylinder 30 is collected in the storage 82.
  • a pressure monitoring device 83 is connected to the conduit 81.
  • This pressure monitoring device 83 controls the biasing valve 84 in such a manner that the valve is switched from its shown position in which the conduit is interrupted to its open position in which the conduit 81 is connected to the conduit and thus to the pump 74.
  • This connection of the conduit 81 to the pump 74 is accomplished in response to a pressure decrease below a predetermined pressure as ascertained by the pressure monitor device 83.
  • the pump will restore the desired pressure by supplying hydraulic liquid to the pressure conduit 81 whereby such restored pressure will have a value above the minimum pressure to which the monitoring device 83 will respond.
  • end skids or roller 22 may be employed as sensing means for transmitting a signal to the operators cabin in response to contacting an obstacle.
  • control means for intentionally telescoping the end section 25 outwardly would have a control means for actuating the piston cylinder arrangement 29.
