Definitions

  • This invention relates to blade-like attachments for armoured vehicles, and more particularly to dozer-like blades for attachment to armoured recovery vehicles, engineer/repair vehicles and the like.
  • an attachment for an armoured vehicle comprising a dozer-like blade having an operative, earth-moving front surface and, at or adjacent the lower regions thereof, a flat, substantially rearwardly extending stabiliser surface, and a linkage adapted to react between the blade and the armoured vehicle to move the blade relative to the armoured vehicle, the linkage including a lower, fixed length link pivotally attached to, to extend between, the blade and the armoured vehicle, a hydraulic cylinder reacting between the vehicle and the lower link to alter the orientation of the blade relative to the vehicle, and an upper link pivotally attached to, to extend between, the blade and the vehicle, characterised in that the linkage is selectively adjustable to move the blade into:
  • the blade can be used for conventional earth-moving operations.
  • the blade serves as an anchor during winching operations, thus preventing undesirable movement of the tracked hull of the vehicle on the application of substantial forces thereto during winching, while the blade can be located in its third position to act as a stabiliser for the vehicle during actuation of the crane and while heavy loads are being lifted thereby.
  • the blade In the fourth position, the blade can be used for stowage purposes, as a transport bucket or as a workbench.
  • a preferred upper link comprises a pair of hinged arms, one pivotally attached to each of the blade and the armoured vehicle, said arms being lockable relative to one another in any of two or more positions to define a link of differing lengths.
  • An alternative upper link is of telescopic construction, the slidable components of which can be locked in any one of two or more different positions relative to one another to define a link of differing lengths.
  • FIGs. 1 to 3 there is shown an attachment indicated generally at 2 mounted on an armoured vehicle 4.
  • the attachment 2 comprises a dozer blade 6 having a concave front surface 8, rearwardly from the lower edge of which extents a flat, stabiliser surface 10 for reasons to be detailed below.
  • the blade 6 is mounted on a bracket or mounting plate 12 adapted to be secured to the armoured vehicle 4, said mounting of the blade 6 being effected by means of two transversely- spaced linkages each indicated generally at 14.
  • Each linkage 14 comprises a fixed length lower link 16 one end of which is pivotally connected to the rear surface of the blade 6 at a point intermediate the height of the blade and the other end of which is pivotally connected to the bracket 12.
  • Each linkage 14 further comprises an adjustable length upper link 18, said link 18 including hinged arms 20, 22, one end of the arm 20 being pivotally connected at 24 to the upper regions of the rear of the blade 6 and one end of the arm 22 being pivotally connected at 26 to the bracket 12, the other ends of said arms 20, 22 being hinged to one another at 28.
  • Hydraulic cylinders 30 mounted on the bracket 12 include pistons 32 the free ends of which are attached one to each of the fixed length lower links 16.
  • the upper link 18 shown in Fig. 2 is at its longer length, in that holes 34 in each arm 20, 22 are aligned, the link 18 being locked in this longer position by means of a pin 36 extending through the aligned holes 34 best seen in Fig. 1.
  • the hydraulic piston-cylinder arrangements 30, 32 can be actuated to locate the blade 6 in either of the two positions shown in Figs. 4 and 5.
  • the piston 32 is partly extended such that the blade 6 is in an earth-moving position with the lower edge thereof just below ground level.
  • Fig. 5 the piston 32 is fully extended such that a substantial part of the blade 6 is below ground level whereby said blade acts as an anchor for the vehicle 4 during winching operations.
  • the upper link 18 can be altered to a shorter length by removing the pin 36 and pivoting the arms 20, 22 towards one another about the hinge point 28 until holes 38, 40, one adjacent the one end of each arm 20, 22 respectively, are aligned, a pin such as 36 then being located through the aligned holes 38, 40 to retain the link 18 at said shorter length.
  • the piston 32 can be actuated to locate the blade 6 in either of the two positions shown in Figs. 6 and 7.
  • Fig. 6 the piston 32 is partly extended such that the surface 10 on the blade 6 abuts the ground and whereby the blade 6 acts as a stabiliser during lifting operations by a crane mounted on the vehicle 4.
  • the blade When the blade is in its substantially horizontal position, it can be used for other purposes, such as a transport bucket for carrying earth and the like, or for extra storage space for carrying auxiliary equipment, or the surface 8 could be used as a workbench.
  • Figs. 8 to 10 The attachement of Figs. 8 to 10 is similar to that of Figs. 1 to 3 and components equivalent to those of the attachment of Figs. 1 to 3 are similarly referenced.
  • this embodiment instead of hinged upper links 18, this embodiment includes telescopic links 18' comprising an outer box section 42 one end of which is pivotally mounted to the bracket 12 and in the other end of which is slidably mounted an inner section 44, the end of said section 44 remote from the section 42 being pivotally attached to, adjacent the upper regions of, the blade 6.
  • the section 44 is provided with a pair of axially-spaced holes, one of which is referenced 46, either of which can be aligned with a corresponding hole 48 through the section 42.
  • Fig. 9 shows the upper link 18' at its longer length, enabling the blade 6 to be pivoted by means of the piston 32 into the positions shown in Figs. 4 and 5.
  • the box section 44 is pushed further into the section 42 to align the other hole in said section 44 with the hole 48 in the section 42. This then enables the blade 6 to be located in positions equivalent to those of Figs. 6 and 7 by appropriate actuation of the piston 32 in the cylinder 30.
  • a blade-like attachment for an armoured vehicle which serves a four-fold purpose in that it comprises a dozer-blade capable of an earth-moving function, capable of acting as an anchor when winching by means of a winch mounted on the vehicle, capable of acting as a stabiliser when lifting loads by means of a crane mounted on the vehicle, and capable of a stowing function.
  • linkages 14 can be other than shown and could be such as to be located in an infinite number of positions by means other than hydraulic, for example pneumatic, mechanical, electronic and the like, while the means for locking the blade in a given position could comprise pins, stops, clamps or other mechanisms.
  • the attachment can be fitted to armoured recovery vehicles, repair/engineer vehicles, battle tanks and the like, while the attachment could be of modular construction to fit various vehicles or specially tailored to suit a particular vehicle.
  • the driving mechanisms for pivoting the blade could be self-contained within the attachment or located remote therefrom.
