Description

(54) METHOD AND APPARATUS FOR CHANGING BATTERIES ON ELECTRIC VEHICLES (71) I, GRAHAM CLENTON RAWLINS, a British Subject of 'Hylton', 401 Turnhurst Road, Packmoor, Stoke-on-Trent, Staffordshire do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to a method of and apparatus for use in changing batteries on electric vehicles, particularly on mineworking locomotives.
A battery in an electric locomotive for underground use in mines weighs approximately six tons and the removal of a battery for recharging, together with the loading of a replacement battery, has proved a laborious job involving a team of four or six operators.
It is an object of the present invention to provide a method of, and apparatus for, changing batteries which is much less laborious and less time consuming, and will involve fewer operators.
According to the present invention there is provided a method of changing a battery on an electric vehicle, comprising providing a support frame on each side of a track for the vehicle, aligning, in a respective vertical plane, corresponding slides of the support frames with corresponding slides on the vehicle by relative movement of the support frame slides and the vehicle, adjusting the height of at least those ends of the support frame slides which are adjacent to the vehicle so as to obtain a horizontal alignment between the adjacent ends of the respective slides, connecting the vehicle battery which is to be replaced to a replacement battery on one of the support frames and moving the connected batteries such that the battery to be replaced is transferred from the vehicle to the other of the support frames on the respective slides and simultaneously the replacement battery is transferred from said one support frame to the vehicle on the respective slides.
According to the present invention there is also provided apparatus for use in changing a battery on an electric vehicle, said apparatus comprising a pair of support frames each having slides capable of supporting a vehicle battery for movement therealong, means on each frame for adjusting the height of the slides at one end thereof, the frames being positioned, in use, on opposite sides of a track for a vehicle with their corresponding slides in alignment in respective vertical planes and said one ends thereof adjacent to the track, and drive means provided on one of said frames and having means for connecting with the battery which is to be replaced so as to impart controlled movement to the battery from a vehicle on to the slides of a first of the support frames and simultaneously move a replacement battery from the slides of the second of the support frames on to the vehicle.
Preferably, said drive means is provided on said first support frame and is connectible with the battery to be replaced to pull the latter off the vehicle, means being provided for connecting the battery to be replaced with the replacement battery.
Preferably also, said drive means comprises an hydraulically operated pistoncylinder assembly operable from an hydraulic power pack on said first support frame.
Advantageously the means for adjusting the height of the slides comprises hydraulically operated piston-cylinder assemblies defining a pair of ground-engageable legs for each of the support frames.
An embodiment of the present invention will now be described by way of example only with reference to the accompanying drawing which is a perspective view of an apparatus according to the invention.
Referring to the drawing, apparatus for use in changing batteries underground in an electric locomotive used in mines, comprises a first support frame 10 of generally rectangular configuration mounting on its upper side three laterally extending, parallel slides 12, Two of the latter i.e. slides 12a, 12b, extend along respective side edges of the frame 10 and have flanges 14 on their outer edges. The third of the slides, i.e. slide 12c is positioned centrally of the two slides 12a, 12b.
The frame 10 has four ground-engaging legs, the legs 16 at one side of the frame being defined by double-acting piston-cylinder assemblies 18 which are preferably hydraulically controlled (not shown) by an hydraulic power pack or motor 20 mounted within the frame 10.
The slides 12 extend from said one side of the frame 10 and terminate short of the other side. A piston-cylinder assembly 22 is mounted towards said other side of the frame 10 at each side edge thereof by means of brackets 23 and supports 24, such that the piston rod travels in a path aligned with and above the respective slide 12a, 12b.
At the free end of the piston rod of each assembly 22 there is provided a lug 25 having a pair of projecting legs 26 each with an aperture 28.
A second support frame 30 of generally rectangular configuration mounts on its upper side three laterally extending, parallel slides 32, which are so spaced apart as to be capable of aligning in vertical planes with respective ones of the slides 12 of the frame 10. Two of the slides 32, i.e. slides 32a, 32b have flanges 34 on their outer edges and are positioned along respective side edges of the frame 30 to align with the slides 12a, 12b respectively and the third of the slides can align with the slide 12c.
The frame 30 has four ground-engaging legs the legs 36 at one side of the frame being defined by double-acting pistoncylinder assemblies 38 which are preferably hydraulically operated and can be connected in the hydraulic circuit of the motor 20.
In use, the frames 10 and 30 are positioned in a locomotive shed on opposite sides of a track (not shown) for the locomotive such that the slides 12 and 32 are aligned in respective vertical planes with the legs 16 and 36 adjacent to the track.
When an electric locomotive requires a battery change it is driven into a position in the shed such that battery slides on the locomotive are aligned in the respective vertical planes of the slides 12 and 32.
By means of manually operable controls (not shown) the piston-cylinder assemblies 18 are hydraulically operated to raise or lower the slides 12 at that side of the frame 10 until the ends of the slides 12 are in horizontal alignment with the adjacent ends of the battery slides of the locomotive. The assemblies 38 are then similarly operated to horizontally align the ends of the slides 32 with the adjacent ends of the battery slides of the locomotive.
The piston rods of the assemblies 22 are then extended and the lugs 25 connected to lugs on the battery to be replaced by means of detachable steel pegs (not shown). The battery to be replaced is also connected to a replacement battery loaded on the frame 30 by means of a detachable link or tow bar (not shown).
Thus, when the piston rods of the assemblies 22 are retracted the battery to be replaced is pulled away from the locomotive on to the slides 12 and simultaneously the replacement battery is pulled along the slides 32 into the locomotive. The flanges 14, 34 retain the batteries on the slides.
The apparatus described above enables batteries to be changed quicker and easier than before and involves fewer operators, e.g. one or two.
Various modifications may be made without departing from the invention as defined in the appended claims. For example, the control of the adjustable components may be other than hydraulic, the frames may be of any suitable form or configuration, and the form of the slides may also differ.
