Description

DETAILED DESCRIPTION OF THE INVENTION Typically, the engine, hydraulic pump, valves and other operating components of a hydraulic excavator are protected in an enclosure.

The engine is mounted at the rear of the rotatable upper unit of the four-wheel drive unit and is counterbalanced by a boom and its attached work equipment mounted at the front of the upper unit. Also, a counterbalance is often removably attached to the rear of the upper frame to assist in balancing during operation.

For example, Stanley A.
No. 479 to 330 (filed May 18, 1972), et al. It is possible to install the polymerization switch and read the instruction manual. A heavy structural support (Agav
y atrotuaL 5upport) is required. This support is bulky and unduly increases the complexity and overall length of the enclosure.

Typically, a standard enclosure has a frame structure to which a plurality of panels are removably attached and six or more panels for accessing and serving the above-mentioned operating safety located within the frame structure. There is. Manufacturing and assembly tolerances often result in holes in the mountings formed in the panel and holes in the mountings formed in the frame structure on the underside of the panel.

Therefore, in addition to the enclosure assembly, new holes must be made in the nosonel or frame structure to compensate for this misalignment.

The object of the present invention is to use an object to preserve the working view of a vehicle, to have a good preservation ratio and structure, and to be able to assemble quickly. The aim is to solve the problems briefly mentioned above by providing a less cumbersome and tube-side enclosure 1. This siege.

For example, the counterbalance chamber includes a frame structure to receive the heavy loads applied when it is attached to the rear of a vehicle. The frame structure includes a pair of center and rear struts coupled together in the direction of the pitcher, and these center and rear struts are fixed to the frame of the vehicle and carry the loads interconnected by a force carrier to the center strut. and transmit directly to the frame.

Preferably, the central struts each have a substantial base fixed to the struts to aid in the load transfer benefits described above.

Additionally, the valley center column has an attachment formed in the frame structure and a top panel attached thereto;
It is preferred to have a mounting plate adjustably mounted on the column to compensate for misalignment of the through mounting holes. At least one upright lateral mother flannel.

Preferably, it is adjustably attached to the enclosure to compensate for misalignment between the upper end of the upright side flannel and the top panel connected thereto.

Other objects of the invention will become apparent from the following description and the drawings.

No. 11W shows the engine enclosure 10 and driver's cabin 11 installed on the upper unit 12 capable of rotating the hydraulic excavator (not shown in its entirety), as shown in FIG. 13 is disposed within the enclosure to counterbalance a boom and its attached working equipment (not shown) movably mounted in a conventional manner on the front end of the upper unit. The upper unit includes a frame 14 having a plurality of rectangular top panels 15-21 secured thereto by means such as bolts 22 located at the corners. As seen in FIG. 1, the top panels 15-21 each have four through-holes at each corner.

A fuel tank 23 installed at the front corner of the enclosure is integrally fixed to the frame. A plurality of threaded holes 24 (FIG. 2) formed in the frame receive the threaded ends of the bolts 22. Each of a pair of laterally spaced and upright rear struts 25 and 26 includes:
Its upper end.

It preferably consists of a U-shaped groove-shaped member 27 fixed to an L-shaped crossbar 28 extending laterally across the width of the frame (see No. 31).

A counterbalance chamber (129) of the type shown in the above-mentioned US If 11 patent M&795,330 is fixed to the outside of the rear strut and moves one or more counterbalance chambers 30.
” installed in Noh. Rear strut #i, more.

The lower #1 portion is fixed by a bolt 32 to the rear end of a frame member 31 arranged in the longitudinal direction. A pair of laterally spaced and standing central columns 33 each have a sizable base or pedestal fixed to the lower end thereof and attached to frame member 31 by bolts 34 and 35. (pedestaL).

The valleys of the central column can be composed of a plurality of plates that are properly connected in fFr contact and form a box-like section that exhibits considerably greater structural protection and strength than the rear column oriented toward the potato. can. Force transmission means, such as tie rods 36, interconnect the upper ends of the center column and rear column. Such a structure increases the structural stiffness of the rear strut and will counterbalance the loads applied to the rear strut by the sheath 30.

Referring to FIGS. 3-5, each central column has a pair of laterally extending ear-shaped racks (38'tl).
Each racket, which also includes a cantilevered portion 37 extending in the -4' direction, has a vertical aperture 39 therethrough, as clearly shown in FIGS. 4 and 5. The installation plate 40 is removably attached to the bracket by a pair of bolts 41 extending through a retaining plate 42 disposed below the bracket. Spacer bushings 43, each mounted on the bolt and located between the support plate and the mounting plate, have a diameter considerably smaller than the diameter of the hole 39 and have a limited horizontal orientation of the mounting plate on the bracket. v4
Let m be +=J-no. The mounting plate has a plurality of threaded holes 44 for receiving the threaded ends of the ports 22.

Explaining with reference to FIGS. 6 and 7, the surrounding lO is
a substantially vertical front panel 4 located centrally on its front surface;
5. One side of the panel is located adjacent to the fuel tank 23 (FIG. 1), and one corner of its lower end is extended laterally -1 inwardly from the fuel tank by means of a fastening such as a port 46. It is fixed to four support brackets.

The opposite side of the I9 channel is secured midway between its upper and lower ends by a bolt 48 to a support bracket 49 extending laterally inwardly from the main frame.

A laterally arranged bracket 50 is fixed to the upper S trailing edge of the -Ai 1 side 9 panel 45, and a pair of threaded holes are connected to the hole 51 and a cylindrical pin protruding on each side of the /# panel. That is, it has a rod 52. #! One member 53 extends laterally inward 1 UtlK from the fuel tank, and a second member 54 extends laterally inwardly from the support frame force λ.

These members are in practical alignment with racket 5G and are each horizontally disposed and open forwardly so that the rods receive the bins 52 and form a connection between the bins and the slot. It has a U-shaped hole 55. When assembling the enclosure, the root 46
Loosen and 48, front side Zenel 45 and bracket 5
0, the installation hole formed in the groove 19 and the threaded hole 51 on the lower side of the groove 5G are precisely aligned to receive the bolt 22. be able to.

That is, the front detail panel 45, as seen in FIG. gi and FIG. Bolt 48, pin 52 and bolt 22 are restrained. A bolt 46 threadably engages a support bracket 47 which passes through the panel 45 at one corner of its lower end and is mounted proximate to the fuel tank 23. (Figure 2) Porto 48 is Porto 4
The opposite 111-t' panel of 6 is threaded through the channel between the upper and lower ends of the channel 45 and is threadedly engaged with a support bracket 49 projecting from the frame towards the fuel tank 23 as shown in FIG. There is.

Bins 52, 52 project in opposite directions from brackets 50 secured to the upper rear edge of the front side armpits 45, as shown in FIG.
3 and the U-shaped slot formed in the second member 54) 55,5
5 can be inserted.

Tighten the bolts 46 and 48 appropriately and tighten the bolts 52.
By sliding the bolt 52 back and forth tightly within the slot 55, the threaded mounting allows the hole 51 and the through installation hole of the top nosonnel 19 to be vertically aligned to receive the bolt 22.
