Abstract
A battery-powered aircraft belt-loader vehicle (10) with a low profile comprises a pair of steerable ground-engaging front wheels (14), a pair of ground-engaging rear drive wheels (16) driven by a pair of electric motors (38), a battery pack (28) connected to power the motors and supported on the vehicle frame (12) to one side of the frame center line (18), and a belt conveyor (50) mounted on the frame (12) on the other side of the center line (18). The belt conveyor can be raised and tilted by power cylinders (62,72). Personnel tending the belt conveyor can stand on horizontal surfaces of a battery cover (30), wheel cover (36), control compartment cover (42), and hydraulic equipment compartment (80). The covers (30,42) are hinged to facilitate servicing access. <IMAGE>
Description
SPECIFICATION
Low profile aircraft belt loader
This invention relates generally to low profile belt loaders and, more particularly, to such loaders which are battery powered.
The present invention provides a battery powered aircraft belt loader which has a low profile, a particularly desirable attribute since machines of this type are operated in close proximity to the aircraft they service, which is relatively compact and which is arranged so that service and routine maintenance may be easily and quickly achieved. The arrangement of certain components provide a work platform usable by personnel tending the loader.
Other attributes and desirable features of the present invention will become readily apparent from the perusal of the following description and accompanying drawing wherein:
Figure 1 is a side elevational view of an aircraft belt loader according to the present invention; and
Figure 2 is a top plan view of the aircraft belt loader shown in Fig. 1, but to a larger scale.
Referring to the drawing, an aircraft belt loader indicated generally at 10, includes a frame 1 2 which is supported by a pair of steerable wheels 1 4 near its forward end and a pair of drive wheels 1 6 near its rearward end. The frame 1 2 has a longitudinal or fore and aft center line, in plan view, as shown at 1 8 in Fig. 2. An operator station, indicated generally at 20, is positioned to one side of the center line and forward of the steerable wheel on that side and includes a steering wheel 22, instrument and control panel 24, and a seat 26.A battery pack 28, which is the power source for the loader 10, is supported by the frame 1 2 and is positioned on the same side of the center line 1 8 as, and just behind, the operator station 20. The pack 28 substantially fills the space between the drive and steerable wheels from the center line 1 8 to the outboard edge of the loader. A battery cover 30 is hinged at 32 to pivot about an axis transverse to the center line 1 8.
Releasable latches 34 hold the cover 30 in its closed position, as indicated in Fig. 1. When latches 34 are released, the cover 30 may be pivoted about hinges 32, as indicated by arrow 35 in Fig. 1, to lay against the adjacent wheel panel 36, which wheel panel covers the drive wheel 1 6 and its associated drive motor 38.The electrical controls for switching and voltage control between the battery pack 28 and drive motors 38 are contained within a control compartment 40 which is provided with a cover 42 hinged at 44 to pivot, as indicated by the arrow 45 in Fig. 1, about an axis transverse to the center line 1 8. The upper surfaces of the battery cover 30, the wheel panel 36 and the control cover 42 lie in substantially the same horizontal plane and thereby provide a level platform for use by personnel working on or around the loader 10.
A belt conveyor indicated generally at 50 includes a driven belt 52 mounted on a conveyor frame 54. A rear lift link 56 is pivoted to the loader frame 1 2 by pivot tube 58 and is pivoted to the conveyor frame by pin 60. A rear lift cylinder 62 has its head end pivotally attached to a cross member 64 and its rod end pinned to the cross members 66 affixed between the arms of link 56.
Extension of the cylinder 62 will cause the rearward end of the conveyor 50 to be elevated, and retraction will lower it. A front lift link 68 is also pivotally attached to the loader frame 1 2 through pivot tube 70 and to the forward end of conveyor frame 54 by means of rollers trapped in oppositely facing channels (not shown) carried by the conveyor frame. A front lift cylinder 72 has its head end pivotally attached to the frame 1 2 through cross tube 74 and its rod end pivotally attached to the cross members 76 secured between the arms of link 68. Similar to the rearward end, extension and retraction of cylinder 72 will result in raising and lowering the forward end of belt conveyor 50.Because the drive wheels 1 6 are powered by individual electric motors 38, there is no rear axle transversing the frame 1 2 and the hydraulic cylinder 62 may be placed as low as possible, consistent with strength and movement arm relationships necessary to achieve pivoting of rear link 56 about tube 58. The hydraulic system, i.e., the hydraulic pump, reservoir, relief valve, tubing, as well as the electric motor for driving the pump,.is placed in the hydraulic compartment 78 which is positioned between the wheels 1 4 and 1 6 and outward of the conveyor 50 substantially filling the space. A cover 80 encloses the compartment 78 and may also be used as a step or walkway by personnel.
As will be appreciated from the foregoing description, the present invention provides a relatively compact arrangement for the components of an electric drive aircraft belt loader which permits service and inspection of the battery and electrical controls without interference from the belt conveyor. The covers for these components in conjunction with the panel for the drive wheel on that side provide a wide platform for personnel to use in tending the belt and its contents. By positioning the battery on one side of the machine's, fore and aft center line, a channel or depression is formed to accept the conveyor lift linkage when it is fully lowered. This achieves a low profile for the loader. In short, the arrangement of the major components provides an aircraft belt loader with thqse attributes necessary or desirable on such a machine.
