Definitions

  • An enclosure normally covers and protects the engine, hydraulic pumps, valves and other working components of a hydraulic excavator.
  • the engine may be mounted at the rear of the excavators rotatable upper unit to aid in counterbalancing the boom and attached implement mounted on the front ofthe upper unit.
  • Ad ditional counterweights are oftentimes releasably attached on the rear of the upper frame to further aid in such counterbalancing during excavator operation.
  • a counterweight installation and removal device such as the one disclosed in U.S. Application Ser. No. 254,496, filed on May 18, l972now U.S. Patent No. 3,795,330, by Stanley A. Jorgensen et al. for COUN- TERWEIGHT SUSPENSION DEVICE, and assigned to the assignee of this application, may be attached on the engines enclosure to aid in the mounting and demounting of such counterweights.
  • Heavy structural supports are normally required at the rear of the enclosure to accommodate the heavy loads imposed thereon by the counterweights. Such supports are bulky and unduly increase the complexity and overall length of the enclosure.
  • the standard enclosure normally comprises a frame structure having a plurality of panels removably secured thereon to provide access to the aforementioned working components disposed therein.
  • a stack-up of manufacturing and assembly tolerances frequently re sults in the misalignment of attachment holes formed through the panels and in the underlying frame structure.
  • new attachment holes compensating for such misalignment must be formed through the panels or frame structure during assembly of the enclosure.
  • An object ofthis invention is to overcome the above, briefly described problems by providing a non-complex and economical enclosure particularly adapted to protect working components of a vehicle, which exhibits a high degree of protection, structural integrity,-and ability to be fabricated expeditiously.
  • the enclosure comprises a frame structure which is adapted to accommodate heavy loads imposed thereon when a counterweight is attached on the rear of the vehicle, for example.
  • the frame structure comprises pairs of longitudinally alinged center and rear posts secured to the vehicles main frame and interconnected by force transmitting means to transmit loading forces to the center posts and main frame directly.
  • the center posts each preferably have a substantially large base secured thereon to aid in such load transmitting desiderata.
  • each center post preferably has a mounting pad adjustably mounted thereon to compensate for the misalignment of attachment holes formed in the frame structure and through a top panel attached thereto.
  • At least one side panel is preferably attached on the enclosure for adjustment to compensate for misalignment between the upper end thereof and a connected top panel.
  • FIG. 1 is an isometric view of an engine enclosure for the upper unit of a hydraulic excavator
  • FIG. 2 is a top plan view of a frame structure employed in the enclosure
  • FIG. 3 is an enlarged side elevational view of a portion of the frame structure, taken in the direction of arrows IIIIII in FIG. 2;
  • FIG. 4 is enlarged, top plan view of a mounting pad for mounting top panels of the enclosure on the frame structure;
  • FIG. 5 is a sectional view of the mounting pad, taken in the direction of arrows VV in FIG. 4;
  • FIG. 6 is an enlarged sectional view of the enclosure, taken in the direction of arrows VI-VI in FIG. 1;
  • FIG. 7 is a top plan view, taken in the direction of arrows VIIVII in FIG. 6 and rotated ninety degrees.
  • FIG. 1 illustrates an engine enclosure 10 and operators cab 11 mounted on a rotatable upper unit 12 of a hydraulic excavator (not fully shown).
  • engine 13 is disposed in the enclosure to aid in counterbalancing a boom and attached implement (not shown) movably mounted on a front endof the upper unit in a conventional manner.
  • the upper unit comprises a main support frame 14 having a plurality of rectangular top panels 15-21 secured thereon by fastening means such as bolts 22, each disposed at a corner of each panel.
  • a plurality of threaded attachment holes 24 are formed in the frame members for receiving the threaded ends of bolts 22.
  • a pair of laterally spaced and upright posts 25 and 26 each preferably comprise a U-shaped channel member 27 secured at its upper end to an L-shaped cross-bar 28, extending transversely the full width of the main frame (FIG. 3).
  • the rear posts are further secured at their lower ends to a rear end of longitudinally disposed main frame members 31 by. bolts 32.
  • a pair of laterally spaced and upright center posts 33 each have a substantially large base or pedestal secured to it lower end and attached to members 31 by bolts 34 and 35.
  • the center posts may each comprise a plurality of plates suitably welded together to form a box-section exhibiting a substantially higher structural rigidity and strength than a longitudinally aligned rear post.
  • Force transmitting means such as tie rods 36, interconnect the upper ends of the center and rear posts.
  • Such construction increases the structural rigidity of the rear posts to accommodate the loads imposed thereon by counterweight 30.
  • each center post further comprises a forwardly extending and cantilevered section 37 having a pair of ear-like mounting brackets 38 extending laterally therefrom.
  • Each bracket has a vertical bore 39 formed therethrough, as clearly shown in FIGS. 4 and 5.
  • a mounting plate 40 is releasably at tached on the brackets by a pair of bolts 42, extending through a retainer plate 42 disposed beneath the brackets.
  • a spacer bushing 43 mounted on each bolt and disposed between the retainer and mounting plates, has
  • the mounting plate has a plurality of threaded attachment holes 44 formed therethrough, adapted to receive the threaded ends of bolts 22 therein.
  • enclosure has a substantially vertical front panel 45 disposed centrally at the front thereof.
  • One side of the panel is positioned adjacent to fuel tank 23 (FIG. 1) and one lower corner thereof is secured by fastening means, such as a bolt 46, to a support bracket 47 extending laterally inwardly from the fuel tank.
  • the opposite side of the panel is fastened intermediate to its upper and lower ends by a bolt 48 to a support bracket 49, extending laterally inwardly from the main frame.
  • a transversely disposed bracket 50 is integrally secured to the upper, back edge of front panel 45 and has a pair of threaded attachment holes 51 formed therein and a cylindrical pin or rod 52 projecting outwardly from each lateral end thereof.
  • a first member 53 extends laterally inwardly from the fuel tank and a second member 54 extends laterally inwardly from the support frame.
  • Such members are in substantial alignment with bracket 50 and each has a horizontally disposed and forwardly opening U-shaped slot 55 formed therein to receive rod 52 to provide a pin and slot connection thereat.
  • bolts 46 and 48 may be loosened to permit fore and aft adjustment of front panel 45 and bracket 50 to precisely align the mounting holes formed through panel 18 with threaded attachment holes 51 of underlying bracket 50 for reception of bolts 22 therein.
  • a vehicle enclosure comprising:
  • At least one top panel having mounting holes formed therethrough
