LOCKING ARRANGEMENT
The present invention relates to a locking arrangement, and in particular, to a locking arrangement which.is useful for adapting wear plates to equipment, such as that utilised in the mining industry, in washeries, or for crushing, etc..
At present, in applying wear plates to earthmoving equipment, it is necessary to separately weld a multiple number of wear plates to the exterior surfaces of the said earthmoving equipment.
Mining equipment wear plates for instance are applied to earthmoving equipment to reduce the wear to the equipment itself. Instead of the actual equipment being worn, the wear plates are worn, the wear plates then being able to be relatively easily replaced at the required periods of time.
This reduces the unnecessary fabrication of earthmoving equipment, by increasing the working life of said equipment.
At present, earthmoving equipment wear plates are constructed of extremely hard, abrasive resistant material which is designed to resist wear. These earthmoving equipment wear plates, are constructed in sections, and each is separately welded to the surface of the earthmoving equipment. As will be appreciated, this welding operation, in attaching the earthmoving equipment wear plates to the earthmoving equipment, is extremely time consuming, resulting in, not only excessive time and man hours being spent in welding the wear plates to the earthmoving equipment, together with very long downtimes of the equipment itself, but also, the earthmoving equipment wear ~~N~.~
plates are prone to become dislodged from the earthmoving equipment due to difficulty in successfully welding the abrasive resistant material to the dissimilar parent material of the equipment.
The present invention seeks to overcame the disadvantages of the prior art, by providing a simple and easy application method and apparatus for attaching the wear plates to the earthmoving equipment.
The present invention also seeks to overcome the .
necessity to weld each and every wear plate to the earthmoving equipment, by providing a quick and simple interlock means to securely attach the wear plates to the equipment.
In one broad form, the present invention comprises a locking arrangement for locking a plurality of plate members to a base surface, said base surface being provided with a plurality of locking anchors pravided in spaced apart . relationship thereon, each of said plate members being provided with at least one anchor receiving member thereon, each of said anchor receiving members being adapted to engage one of said anchors, such that, the edges of each said plate members are adapted to abutt with the edges of adjacent plate members, with the outer plate members being adapted to abutt retaining . members being affixed to said base surface such that, each of said plate members is thereafter prevented from disengagement from said anchors.
Tn a further broad form, the present invention provides a method of applying~a plurality of plate members to a base surface, said base surface having a plurality of anchors . 2021~~6 provided in spaced relationship thereon, and said plate members each having at least one anchor receiving portion thereon, said method comprising the steps of:
supplying a first of said plate members onto said base member by providing said at least one anchor receiving portion thereof in engagement with a said respective one of anchors;
supplying further plate members onto said base member, each of said plate members being supplied in end abutting relationship with plate members subsequently supplied to said base member, such that, provision of plate members in such position prevent subsequently applied plate members from disengagement from said anchors; and, supplying retaining members, around at least one periphery row of plate'members to abut with and consequently retain said plate members to said base plate.

LOCKING ARRANGEMENT
The present invention relates to a locking arrangement, and in particular, to a locking arrangement which.is useful for adapting wear plates to equipment, such as that utilised in the mining industry, in washeries, or for crushing, etc..
At present, in applying wear plates to earthmoving equipment, it is necessary to separately weld a multiple number of wear plates to the exterior surfaces of the said earthmoving equipment.

In Fig. 1, an isometric view of a wear pad or wear plate for equipment such as that utilised in mining, washeries or crushing mills, is shown. such an equipment wear pad can be adapted, by use of the moon lock arrangement in accordance with the present invention, to an equipment. The wear plate arrangement, generally designated by the numeral 1, comprises a ri ,..; , ';~",p... _, . . . .
body section 2, with a number of wear plate protrusions 3 spaced thereon, as required in accordance with the particular application of use. Any method of applying the wear plate protrusion 3 to the body 2 may be utilised. Wear plates are commonly applied to equipment such as earthmoving mining, washery and crushing equipment, to protect the earthmoving equipment from wearing out by constant usage. Rather than the equipment itself wearing out, the wear plates, which can be replaced, are changed after an appropriate amount of use of said equipment.
The preferred embodiment of the present invention will be hereinafter described with reference to the wear plates of the present invention being adapted to earthmoving equipment. It should however be understood that the invention is not limited to such particular application.
Previously however, a suitable method of attaching the wear plates to the earthmoving equipment has not been provided.
At present, it is necessary to weld the wear plates to the earthmoving equipment. As will be appreciated, this is an extremely time-consuming process, when the earthmoving equipment itself cannot be utilised for the purpose of mining.
In Fig. 2 is detailed a plan view of the earthmoving equipment wear plate configuration shown in Fig. 1. Fig. 2 illustrates the spaced apart relationship of the various wear plate protrusions 3 as applied to the body 2.

Fig. 3c shows a cross-sectional view through line BB of Fig. 2, also illustrating the angled protrusion of the two outer wear plate protrusions 3, also in accordance with Fig. 2.
In Fig. 4 is illustrated how several earthmoving equipment wear plate sections may be inter-engaged by means of the moonlock arrangement in accordance with the present invention. The figure illustrates how a plurality of spaced apart moon lock anchors 5 are provided on the exterior surface of a earthmoving equipment. In accordance with the preferred embodiment of the present invention, each wear plate 1 is extended over and adapted to engage two adjacent moon lock anchors 5, which themselves are welded or bolted to the base of the earthmoving equipment. As illustrated in Fig. 4, each separate earthmoving equipment wear plate 1 is located such that the ends thereof abut the two adjacent earthmoving equipment wear plates 1, located ~.n the adjacent rows thereto.
Obviously, however, the wear plates 1 near to the perimeter of the equipment may be varied in size such that, if required,, the edges of each perimeter weat plate 1 may be substantially aligned. This may be achieved by varying the chute size of the individual wear plates. When designing wear plates to fit a specific equipment, it is advantageous to have a computer facility as an aid therefore. For instance, the physical dimensions and constraints may be inputted into the computer and the computer may then automatically calculate the preferred size of the individual wear plates such that they completely cover the external surface of the equipment. By such method, the chute size may be varied in width, breadth and thickness, as required. Each of the moon lock anchors 5 is preferably constructed of mild steel, stainless steel or any other material which is suitable for the application. The wear plates of the present invention may be cast or manufactured out of plate. The adaptor plates may be covered by a variety of wear materials, for example, bisalloy 360 of the like, polyurethane plastics, ceramic tiles, etc.
In Figs. 5a and 5b, are illustrated plan and elevational views of the moon lock anchor construction which may be bolted to the earthmoving equipment by means of three bolts applied through the bores 6. Alternatively, the earthmoving equipment wear plate anchor may be attached to the earthmoving equipment by means of welding or any other suitable method of application, or, the moonlock anchors may be cast on as part of original equipment. A suitable construction for an earthmoving equipment wear plate moon lock anchor which may be welded to the earthmoving equipment is illustrated in Figs. 5c and 5d, Fig. 5c illustrating a plan view thereof, and Fig. 5d illustrating an elevational view thereof.
In Fig. 6 is detailed a plan view and an elevational view of the moon lock adaptor plate, which is designed to . , . 2~~~.~ ~~
~nter-engage with the moon lock anchor 5 illustrated in Fig.
5. The base plate 7 of the moon lock anchor is provided with two cut-outs 12 thereon, each of the cut-outs being formed of a substantially rectangular section 8 and a semi-circular section 9. The curved edge of the semi-circular section 9 is tapered, corresponding to the taper 12 on the moon lock anchor 5 illustrated in Fig. 5. Also shown in Fig. 6 are cut-out portions 11, which are cut out for the purpose of reducing the weight of the adaptor plate 7 and consequently, the weight of the earthmoving equipment, and, also, to allow the plug welding of wear plates to the adaptor plate.
In Fig. 7, is illustrated a plan view of a moon lock adaptor plate 7 specifically designed for a earthmoving equipment wear plate, which has been cast in one section. The view shown in Fig. 7 is that of the underside of the moonlock adaptor plate 7.

Fig. 8a illustrates the earthmoving eguipment wear plate protrusions 3 at spaced apart locations upon the body 2 of the wear plate. Fig. 8a also illustrates the adaptor plate portion 7 of the wear plate with each of the shaped cut-outs 12 thereon.
In Fig. 9 is illustrated a partially exploded isometric view of a moon plate arrangement as applied to a sled base, this arrangement also then provided with a bull nose retainer plate. As illustrated, each of the wear plates 13 are, one at . f a time' provided over a pair of anchors 15, upon the base ~~~l~~j~
structure 16. Once each of the wear pads 13 are applied to the base plate 16, the bull nose retainer 14 is then applied adjacent one end thereof. The bull nose retainer 14 may be welded or bolted or applied to the base plate 16 by any suitable means of connection. Once the bull nose retainer 14 is applied to the base plate 16, the bull nose retainer 14 prevents any lateral movement of any of the wear pads 13, preventing any of the wear pads 13 from disengaging from the base plate 16. Consequently, each and every wear pad 13 is adapted to the base plate 16 on a semi-permanent basis.
In Fig. 10 is illustrated an isometric view of a bull nose keeper which may be welded to the apparatus adjacent to the cast moon plate arrangement as shown in Fig. 9. This bull nose keeper 14 is simply welded or applied by means of bolts or the like to the earthmoving equipment after each of the wear pads are applied thereto, to retain the wear pads 13 in position on the earthmoving equipment.
In Fig. il elevational views of the earthmoving equipment wear pads 13 as illustrated in Fig. 9, are shown. Fig. lla illustrates the wear pad 13 with a shaped upper surface effectively providing protrusions 3 thereon, said protrusions 3 being of the format as hereinbefore described, or of any other , appropriate format.

In Fig. 12, is Shown some various alternative embodiments of the underside of the adaptor plate as hereinbefore described. As illustrated, the earthmoving equipment wear plate adaptor plate may take the form of varying shapes, for instance octangular, triangular, square or semi-circular shape, it should be understood that any other shaped anchors and corresponding adaptor plates may be provided, to achieve the same function of connection of the locking arrangement as hereinbefore described.
It should be understood to people skilled in the art that numerous other variations and modification can be made to the invention as hereinbefore described. Such variations and modifications should however be considered to be within the scope of the present invention as broadly described hereinbefore and as claimed hereinafter.
Fig. 3c shows a cross-sectional view through line BB of Fig. 2, also illustrating the angled protrusion of the two outer wear plate protrusions 3, also in accordance with Fig. 2.
In Fig. 4 is illustrated how several earthmoving equipment wear plate sections may be inter-engaged by means of the moonlock arrangement in accordance with the present invention. The figure illustrates how a plurality of spaced apart moon lock anchors 5 are provided on the exterior surface of a earthmoving equipment. In accordance with the preferred embodiment of the present invention, each wear plate 1 is extended over and adapted to engage two adjacent moon lock anchors 5, which themselves are welded or bolted to the base of the earthmoving equipment. As illustrated in Fig. 4, each separate earthmoving equipment wear plate 1 is located such that the ends thereof abut the two adjacent earthmoving equipment wear plates 1, located ~.n the adjacent rows thereto.
Obviously, however, the wear plates 1 near to the perimeter of the equipment may be varied in size such that, if required,, the edges of each perimeter weat plate 1 may be substantially aligned. This may be achieved by varying the chute size of the individual wear plates. When designing wear plates to fit a specific equipment, it is advantageous to have a computer facility as an aid therefore. For instance, the physical dimensions and constraints may be inputted into the computer and the computer may then automatically calculate the preferred size of the individual wear plates such that they completely cover the external surface of the equipment. By such method, the chute size may be varied in width, breadth and thickness, as required. Each of the moon lock anchors 5 is preferably constructed of mild steel, stainless steel or any other material which is suitable for the application. The wear plates of the present invention may be cast or manufactured out of plate. The adaptor plates may be covered by a variety of wear materials, for example, bisalloy 360 of the like, polyurethane plastics, ceramic tiles, etc.
In Figs. 5a and 5b, are illustrated plan and elevational views of the moon lock anchor construction which may be bolted to the earthmoving equipment by means of three bolts applied through the bores 6. Alternatively, the earthmoving equipment wear plate anchor may be attached to the earthmoving equipment by means of welding or any other suitable method of application, or, the moonlock anchors may be cast on as part of original equipment. A suitable construction for an earthmoving equipment wear plate moon lock anchor which may be welded to the earthmoving equipment is illustrated in Figs. 5c and 5d, Fig. 5c illustrating a plan view thereof, and Fig. 5d illustrating an elevational view thereof.
In Fig. 6 is detailed a plan view and an elevational view of the moon lock adaptor plate, which is designed to . , . 2~~~.~ ~~

The curved edge of the semi-circular section 9 is tapered, corresponding to the taper 12 on the moon lock anchor 5 illustrated in Fig. 5. Also shown in Fig. 6 are cut-out portions 11, which are cut out for the purpose of reducing the weight of the adaptor plate 7 and consequently, the weight of the earthmoving equipment, and, also, to allow the plug welding of wear plates to the adaptor plate.

structure 16. Once each of the wear pads 13 are applied to the base plate 16, the bull nose retainer 14 is then applied adjacent one end thereof. The bull nose retainer 14 may be welded or bolted or applied to the base plate 16 by any suitable means of connection. Once the bull nose retainer 14 is applied to the base plate 16, the bull nose retainer 14 prevents any lateral movement of any of the wear pads 13, preventing any of the wear pads 13 from disengaging from the base plate 16. Consequently, each and every wear pad 13 is adapted to the base plate 16 on a semi-permanent basis.
In Fig. 10 is illustrated an isometric view of a bull nose keeper which may be welded to the apparatus adjacent to the cast moon plate arrangement as shown in Fig. 9.
