[0001] CONNECTING CLEAT FOR CONNECTING DECK RAILS IN VIBRATORY EQUIPMENT
[0002] TECHNICAL FIELD
[0003] The present invention relates to the field of vibratory equipment, in particular vibratory screening machines and vibratory feeders. More in particular, the invention pertains to a connecting cleat for connecting deck rails in such vibratory equipment.
[0004] BACKGROUND
[0005] As is commonly known in the mining and rock industry, vibratory equipment is conventionally utilized in the processing of earth material, for example for the purpose of separating material into fractions, a vibratory screening machine may be employed.
[0006] Materials subject to processing in such vibratory equipment include, not limited to metalliferous and non-metalliferous ore, rock and waste material, various earth materials as mentioned, which may also include soil materials such as coal.
[0007] In keeping with the example of a screening machine, a screening machine comprises a screening deck that receives the subject material. The screening deck comprises one or more deck panels, such as screening media, that are held and supported by an array of transverse cross beams via longitudinal deck rails, otherwise known as deck rails, that abut the deck panels and connecting cleats that connect the stringers with the cross beams. A vibration mechanism is provided and operable to vibrate the cross beams in a per se known fashion, whereby the vibrating movement of the cross beams is transferred to the deck rails and hence deck panels, for processing material thereon by excitation. The vibration mechanism may comprise exciters configured to vibrate the cross beams in accordance with different vibration patterns, such as two- or three-dimensional patterns, depending on application and desired result.
[0008] It is the primary function of the screening media to separate one or more oversize products from a material flow by allowing the finer material to fall through openings in the screening panels, for example to a second screening deck or as a finished product. Although the construction of a vibratory feeder may be similar to that of a screening device, in a vibratory feeder, instead of screening media, the screening deck may comprise blind deck panels, that is, deck panels that are absent openings.
[0009] As with any vibratory equipment, various components of a screening machine that are subject to movement may be stress prone and often dictates longevity of the machine due to fatigue. By way of example, oscillating forces in a screening machine causes significant mechanical stress in the mentioned cross beams that oscillate whilst supporting the load of the material being processed and why the cross beams have been found to be particularly fatigue prone.
[0010] In response to these issues, the applicant has devised a novel arrangement which addresses this problem.
[0011] SUMMARY
[0012] In line with the observations detailed above, the present inventors have made valuable technical insights to solve or at least mitigate one or more of the challenges referred to in the previous section. These insights will be presented as inventive aspects below as well as in the detailed description section, the claims and the drawings to which reference is made. The list of inventive aspects is not to be seen as exhaustive but rather a summary of particularly beneficial inventive aspects.
[0013] Generally, in achieving attachment of a connecting cleat and the cross beam, some form of engagement with the structure of the cross beam is naturally required, such as the provision of through openings in the cross beam for receiving mounting bolts or like at the attachment points. Whilst such through openings infringe the structural integrity of the cross beam and taking into consideration that the cross beam in operation is subjected to stress, the structural infringement may be expected to be accompanied by adverse effects on the fatigue life thereof. These detrimental effects are advantageously eliminated or at least to some extent alleviated by the provision of a deck rail connecting cleat according to aspects of the invention.
[0014] The present invention contemplates the mechanical attachment means may advantageously be provided distanced from such areas or zones of the cross beam that are particularly fatigue prone. In particular, the mechanical attachment means of the cross beam may be provided at respective positions along the circumference of the cross beam that are distanced from the fatigue prone zones and with a desirable clearance thereto in order not to weaken the structural integrity of the cross beam in the vicinity of fatigue prone zones. Indeed, so long as the respective attachment points are sufficiently distanced from the high- stress zones, appreciable benefit may be realized.
[0015] Of course, also the weight of the connecting cleats will impact the magnitude of stress on the cross beams whereby weight saving thereof poses as a potential area of improvement as is also contemplated herein.
[0016] In one aspect, there is provided a connecting cleat for connecting deck rails to a cross beam in a vibratory equipment for processing a soil material, such as a vibratory screening machine or a vibratory feeder. The cleat comprises a cleat body defining a cleat inner circumference that curves about a cleat center axis of the cleat for coaxial arrangement with a correspondingly curved cross beam outer circumference of the cross beam.

In some aspects, an end plate center plane of the end plate forms a central offset angle with the cleat center plane at the cleat center axis in the axial plane. The offset angle may be greater than zero. In some aspects, the central offset angle is in in the range of 5 to 55 degrees. In some aspects, the offset angle is in the range of 25 to 35 degrees. In some aspects, the offset angle is about 30 degrees.
[0025] In some aspects, the curved cleat inner circumference is arc-circular in the axial plane and extends at least between the cleat first aperture to the cleat second aperture.
[0026] In some aspects, a width of the cleat body extends along the cleat center axis, wherein the width tapers from opposite free end portions of the cleat.
[0027] In some aspects, the cleat body is a cast element and the end plate is provided welded to the cleat body.
[0028] In some aspects, opposite cleat end portions of the cleat body form a central second angle at the cleat center axis. The second angle may be in the range of 132 to 242 degrees. In some aspects the second angle is in the range of 180 to 200 degrees. In some aspects, the second angle is about 222 degrees.
[0029] In some aspects, the end plate has an end plate center plane parallel the cleat center axis, wherein the end plate center plane forms respectively with the first attachment means a central seventh angle at the cleat center axis, and a central eighth angle with the second attachment means at the cleat center axis, wherein the central eighth angle is greater than the central seventh angle. For example, the eight central angle may be 1.5 times greater than the seventh central angle.
[0030] In some aspects, the end plate has an end plate center plane that is parallel to the cleat center axis. The end plate center plane forms with the first attachment means a central seventh angle at the cleat center axis. The central seventh angle may be in the range of 25 to 85 degrees. In particular, in some aspects the end plate center plane forms with a first cleat aperture center axis of the first cleat aperture the central seventh angle at the cleat center axis.
[0031] In some aspects, the end plate has an end plate center plane that is parallel the cleat center axis, wherein the end plate center plane forms with the second attachment means a central eighth angle at the cleat center axis. The central eighth angle may be in the range of 85 to 140 degrees. In particular the end plate center plane may form with a second cleat aperture center axis of the second cleat aperture the central eighth angle at the cleat center axis. In one aspect, there is provided a vibratory equipment, such as a screening machine or a vibratory feeder, for processing a soil material. The vibratory equipment comprising at least one cross beam, such as a plurality of cross beams, extending in a direction transverse a longitudinal machine direction of the vibratory equipment for supporting a material processing deck of the vibratory equipment. The at least one cross beam comprises one or more connecting cleat, such as a plurality of connecting cleats, according to aspects of the disclosure. The connecting cleat connecting one or more deck rails of the deck to the at least one cross beam.
[0032] In some aspects, the vibratory equipment is configured to vibrate the cross beam such that a cross beam longitudinal center axis of the cross beam oscillates along a stroke line in a plane transverse a cross beam longitudinal center axis. In some aspects, respective first mechanical attachment means and second mechanical attachment means of the one or more cleat are arranged along a cross beam outer circumference of the cross beam to form respective central angles, such as the fifth angle and the sixth angle respectively, with the stroke line at the cross beam center axis. In some aspects, the central angles are in the range of 25 to 140 degrees respectively. In some aspects, the central angles are about 90 degrees.
[0033] In some aspects, the stroke line forms, in a plane transverse the cross beam center axis, a central stroke angle with any one or more of the machine direction and a horizontal plane. The stroke angle may be in the range of 30 to 90 degrees.
[0034] In some aspects, the vibratory equipment is configured to vibrate the cross beam in accordance with a linear vibration pattern.
[0035] In some aspects, the vibratory equipment detailed herein may be configured for processing any of metalliferous and non-metalliferous ore, rock and waste material, various earth materials as mentioned, which may also include soil materials such as coal.
[0036] The aforementioned aspects are associated with a number of advantages.
[0037] For example, one appreciates that by the configuration of the connecting cleat according to aspects of the disclosure, the structural integrity of the cross beam is maintained in the vicinity of the high stress zones, whereby improved fatigue life of the cross beam may be facilitated. Meanwhile, aspects of the disclosure ensure a firm attachment of the cleat to the cross beam. As such, the present invention represents a constructive measure for improving fatigue life of the cross beams of the vibratory machine.
[0038] One also appreciates that the configuration of the cleat in accordance with aspects of the disclosure advantageously facilitates a relatively low weight of the cleat. A reduced mass cleat requires less energy to accelerate, renders the cleat easier to accelerate and thus reduces stress on the cross beam.
[0039] Certain asymmetrical properties of the cleat detailed herein are associated with further advantages, for instance, when the stroke line makes an angle with a horizontal plane or the machine direction, the cleat may still be arranged on the cross beam such as to span well over the fatigue prone zones whilst the end plate is oriented substantially upwards, towards the deck of the vibratory machine.
[0040] Thus, the provision of such connecting cleat according to aspects will solve or at least mitigate at least the drawbacks identified in the background section of this document, while further advantageous embodiments will become apparent from the following description of embodiments of the invention with the aid of the drawings.
[0041] The embodiments of the present disclosure relate to all possible combinations of features recited in the appended claims. Additionally, it will be appreciated that all embodiments described with reference to the first aspect of the present disclosure may be combined with any embodiment described with reference to the second aspect of the present disclosure, and vice versa. The present disclosure encompasses also such embodiments.

[0055] DETAILED DESCRIPTION
[0056] With reference to Fig. 1 and Fig. 2, a vibrating machine 10 will be described by way of example of a vibratory screen similar to the screening machine detailed above. A screen frame 20 comprises opposite arranged side panels 23 extending in a longitudinal direction of the screen. A receiving end 40 is provided for receiving material to be processed in a general process direction along a machine direction S to a downstream discharge end 41, where the machine direction S is along the longitudinal direction of the screen. In particular, a deck 21 receives the material and facilitates the processing of the material. The deck 21 is held and supported by an array of longitudinally extending deck rails 24 fixedly attached to an array of transverse cross beams 12 respectively extending between the side panels 23 and transverse to the machine direction S. One or more vibration device 22 is provided and operable to cause the cross beams 12 to vibrate according to a vibration pattern. The vibrating motion is transferred from the cross beams 12 to the deck 21 for processing material thereon, such as metalliferous and non-metalliferous ore, rock and waste material, various earth materials as mentioned, which may also include soil materials such as coal. The vibration device 22 may comprise or consist of rotating eccentric masses which produce a linear force output / acceleration on the screen deck. The force output can also be circular or elliptical similar to that shown in Fig. 5.
[0057] With added reference to Fig. 2, the deck 21 comprises an arrangement of deck panels 25 connected to the longitudinally extending deck rails 24 facilitating connection between the deck panels 25 and the connecting cleats 30. The deck panels 25 may comprise a plurality of individual elements. The deck rails 24 are respectively connected to the cross beams 12 by means of the connecting cleats 30. Thus, the cleat 30 is configured for transferring forces from the cross beam 12 to the deck panels 25 via the deck rails 24 during operation of the vibratory machine 10. In operation, the deck panels 25 carry the significant load of the material subject to processing. Accordingly, the connecting cleat 30 is designed to withstand substantial forces, such as oscillating forces, over extensive periods of operation without failure. The cleat 30 comprises a cleat body 31 and a connecting portion in shape of a end plate 32 for connecting the deck rails 24 thereto. The cleat body 31 has an inner face 37 that curves about a cleat center axis A1 and defines a cleat inner circumference 37a. The cleat inner face 37 is configured to be arranged coaxial with a cross beam center axis A2 whereby the respective axes A1 and A2 are aligned. The cleat body 31 is provided with at least one first mechanical attachment means 33 and at least one second mechanical attachment means 34 facilitating fixedly attaching the cleat 30 to the cross beam 12.
[0058] As shown in Fig.2, the first mechanical attachment means 33 may be proximal mechanical attachment means provided proximal the end plate 32 and thus proximal the deck panels 25. The second mechanical attachment means 34 may be distal mechanical attachment means provided distal the end plate 32 and thus distal the deck panels 25 in relation to the first mechanical attachment means 34, as will be detailed further in the below. Accordingly, at the respective locations of the mechanical attachment means 33, 34, attachment between cleat 30 and the cross beam 12 may be realized.
[0059] With added reference to Fig.3 and Fig.4, the first mechanical attachment means 33 may in some implementations comprise at least one radially extending through-opening in the cleat 30 that forms a first cleat aperture 33 of the cleat 30. Corresponding at least one first through-opening(s) may be provided in the cross beam 12, forming a first cross beam aperture 14 in the cross beam 12. The first cleat aperture 33 is configured to be aligned with the first cross beam aperture 14 when the cleat 30 is mounted to and coaxially arranged with the cross beam 12. The cleat 30 may thereby be attached to the cross beam 12 at the location of the first attachment means 33 by means of the first aperture 33 of the cleat 30 being at least partially aligned with the at least one first cross beam aperture 14 for receiving therethrough a fastening element, such as a bolt, of a first mechanical fastening arrangement 27, such as a nut and bolt or equivalent fastening arrangement, whereby the fastening element extends through both the first cleat aperture 33 and the first cross beam aperture 14. The first cleat aperture 33 thus facilitates a point of anchorage to the cleat 30 at the first cleat aperture 33. Correspondingly, the first cross beam aperture 14 facilitates a point of anchorage to the cross beam 12. In this sense, the first cleat aperture(s) 33 and in a corresponding manner also the second cleat aperture 34, respectively constitutes mechanical attachment means. The cleat 30 may thereby be fixedly attached the cleat 30 to the cross beam 12.
[0060] In some aspects, the cross beam comprises a first cross beam aperture 14 and a second cross beam aperture 15 provided along the cross beam outer circumference 29a. The first cross beam aperture 14 forms with the second cross beam aperture 15 a central angle at the cross beam center axis A2. The central angle may be in the range of 110 to 220 degrees, such as about 180 degrees. In some aspects, such as shown in Fig. 4 and Fig. 11b, the at least one first cleat aperture 33 comprises a set of neighboring first cleat apertures 33a and 33b. Correspondingly, the at least one cross beam first aperture 14 comprises a set of cross beam first apertures 14, whereby a respective first cleat aperture of the set of first cleat apertures may be aligned with a respective first cross beam aperture of the set of first cross beam apertures, as detailed above.
[0061] The first cleat apertures 33a, 33b of the set of first cleat apertures 33 being arranged axially distanced from each other along the cleat center axis A1. One first cleat aperture 33a of the set of first cleat apertures 33 and the second cleat aperture 34 may be provided in a first axial plane of the cleat 30 and the other first cleat aperture 33b of the set of first cleat apertures 33 may be provided in a second axial plane of the cleat 30 that is displaced from the first axial plane. As seen in a direction along the cleat center axis A1, the first cleat apertures 33 of the set of first cleat apertures 33 may be aligned and overlapping. In any implementation, the cleat 30 may comprises a single second cleat aperture 34.
[0062] Accordingly, the second attachment means 34 comprises at least one radially extending through-opening in the cleat 30 that forms a second cleat aperture 34 of the cleat 30. At least one corresponding second through-opening is provided in the cross beam 12 and forms a second cross beam aperture 15 in the cross beam 12. The cleat 30 may thereby be assembled to the cross beam 12 at the location of the second attachment means 34 by means of the second cleat aperture 34 being at least partially aligned with the second cross beam aperture 15 for receiving therethrough a fastening element, such as a bolt, of a second fastening arrangement 28, such as a nut and bolt or equivalent fastening arrangement, for fixedly attaching the cleat 30 to the cross beam 12.
[0063] The above detailed fastening arrangements 27, 28 may comprise any of standard huck bolts, standard bolts with Nylon insert lock nuts, prevailing torque lock nuts, rivets and swaged collar fasteners or combinations thereof.
[0064] Respective opposite end portions of the cross beams 12, in the longitudinal direction of the cross beam 12, comprises an end flange 13 that mounts to the frame 20, as shown in Fig. 3.
[0065] Further to Fig.4, a width W of the cleat 30 extends along the cleat center axis A1 and the width W comprises a central narrow portion forming a waist at a cleat body center plane Be between a first proximal end portion 38 and an opposite distal second end portion 39. As is further derivable from Fig. 4, the cleat body width W tapers from the opposite cleat end portions 38, 39 towards the central narrow portion. A corresponding end plate width of the end plate 32 may be substantially uniform and may be less than the cleat body width W. The configuration detailed above is beneficial in terms of weight of the cleat 30. Indicated in Fig. 4 is a radius of curvature R of the cleat inner circumference 37a seen in an axial plane A, wherein the center of curvature is at the cleat center axis A1.
[0066] A cleat body thickness T of the cleat body 31 extends in a radial direction of the cleat 30. The cleat body thickness T may be substantially uniform along the circumferential direction of the cleat 30, such as along the cleat inner circumference 37a. The body thickness T may be less than the cleat body width W.
[0067] Referring again to Fig. 2, as has been mentioned hereinbefore, the cross beams 12 may, during operation, vibrate in accordance with various vibration patterns depending on application. In particular, a respective cross beam center axis A2 may, at least substantially, vibrate along a stroke line 50 as seen in an axial plane transverse the cross beam center axis A2. By way of example, vibration patterns may include linear vibration and two- dimensional patterns such as elliptical vibration as will be further elucidated in relation to Fig.5. Fig. 2 however schematically illustrates a vibration pattern wherein the cross beams displace in a linear pattern along what is commonly referred to as a line of stroke (LOS) herein also referred to as stroke line 50.
[0068] Fig. 5 schematically illustrates two exemplary vibration patterns commonly employed by vibratory equipment. In some implementations, cross beam center axis A2 may, during use, vibrate / oscillate along the stroke line 50 having a vertical component in the vertical direction V and a horizontal component, that is transverse the longitudinal center axis A2, such as along the machine direction S.
[0069] The stroke patterns in Fig. 5 are two-dimensional and shown in a plane that is transverse the cross beam center axis A2, corresponding to the axial plane A of the cleat 30. In particular, Fig. 5 shows an elliptical pattern 53 that is an approximation of the dotted elliptical patterns illustrated in Fig. 5 and based on which an equivalent stroke line 50 may be approximated and derived. Similarly, an appreciation of an actual stroke line 50 may be derived from an actual linear stroke pattern that lay within in a stroke sector 51 during operation of the vibratory machine 10, as schematically illustrated in Fig. 5. That is, Fig. 5 shows a proximal stroke sector 51 and a distal stroke sector 52 within which actual lines of stroke may typically divert during operation of the vibratory machine 10. The stoke sectors 51 and 52 may typically have a respective central angle in respect of the cross beam center axis A2 that is in the range of 0 to 45 degrees, typically about 30 degrees.
[0070] The stroke line 50 is commonly understood as a theoretical concept. The stroke line 50 may typically be calculated during design of the vibratory machine 10 and subsequently measured during tests in a per se known manner. Such testing may reveal that determined actual strokes lay within the stroke sector 51. It is noted that in some vibratory machines the stroke line 50 may be variable, such as with respect of the machine direction S, and it should be appreciated that the exemplary illustrations of the stroke line 50 shown herein, such as inclination of the stroke line 50 with respect of a machine direction S, is to be understood as serving the purpose of exemplification.
[0071] In any respect, the implementations of the cleat 30 as detailed herein may be advantageous when employed in vibratory machines applying a linear stroke line 50. Thus, in some implementations the vibratory machine 10 may be configured to vibrate the deck 21 in accordance with a linear stroke pattern, that is, have a linear stroke line 50.
[0072] With general reference to Fig. 4, Fig.6, Fig.7 and Fig.8 certain features of the cleat 30 will be discussed in the below.
[0073] As has been detailed hereinbefore, the cleat center axis A1 is substantially aligned and coaxial with a cross beam longitudinal center axis A2 when the cleat 30 is mounted to the cross beam 12. Fig. 6 to Fig.8 show the cleat 30 in an axial plane A of the cleat 30 that is thus transverse the cleat center axis A1.
[0074] The cleat 30 comprises a cleat body 31 having a curved cleat inner face 37 that curves about the cleat center axis A1 for coaxial arrangement with a correspondingly curved cross beam outer face 29. The cleat inner face 37 defines in the axial plane A, a cleat inner circumference 37a extending in a circumferential direction of the cleat 30, such as about the cleat center axis A1. Correspondingly, the cross beam outer face 29 defines in an axial plane of the cross beam 12 a cross beam outer circumference 29a. The cleat inner face 37 is a surface and has a circumferential extension in the circumferential direction of the cleat body 31, and an axial extension along, such as parallel to, the cleat center axis A1. The cleat inner face 37 may preferably be configured to be brought into surface contact with at least a portion of the cross beam outer face 29, such as when the cleat inner face 37 is arranged coaxial with the cross beam outer face 29.
[0075] The cross beam 12 may in any embodiment be cylinder tubular and thus comprise a circular cross section and thus a circular outer circumference 29a. Thereby the cross beam outer face 29 may in any embodiment have a cylindrical shape. However, other curved shapes are of course conceivable within the spirit of the invention, such as cross beams having elliptical or oval transverse cross sections.
[0076] Thus, in some embodiments, the cleat inner face 37 may have an annular shape. That is, the cleat inner circumference 37a may be arc-circular in the axial plane A.
[0077] The cleat inner face 37 extends between the first end portion 38 and the opposite second end portion 39 of the cleat body 31. Alternatively, or in addition, the cleat inner face 37 extends at least from the first attachment means 33 to the second attachment means 34 of the cleat body 31. Alternatively, or in addition, the cleat inner face 37 extends from the first end portion 38 to the opposite second end portion 39 of the cleat body 31.
[0078] In some embodiments, the first end portion 38 is a proximal end portion that is proximal the end plate 32, the second end portion 39 is a distal end portion that is distal to the end plate 32 in relation to the first end portion 38.
[0079] The first cleat aperture 33 is provided at the first end portion 38. The second cleat aperture 34 is provided at the second end portion 39.
[0080] A radius of curvature R of the cleat inner face 37 may substantially correspond to a radius of curvature of the cross beam outer face 29. However, as will be detailed further in herein, a gasket 26 or like arrangement may be provided and accommodated interspaced between at least a portion of the cleat inner face 37 and at least a portion of the cross beam outer face
[0081] 29. Accordingly, at least a portion of the cleat inner face 37 may comprise a radius of curvature that differ from the outer circumference of the cross beam 29.
[0082] The provision of gaskets 26, 1026, 1126 is associated with a number of advantages, including noise reduction through damping, providing friction between the cleat 30 to the cross beam 12 and thus ease of fitting the cleat 30 to the cross beam 12. Further, gaskets 26, 1026, 1126 prevent water ingress into the cross beam 12 by sealing an exterior of the cross beam 12 from an interior of the cross beam 12. In particular, such gaskets 26, 1026, 1126 may seal between the cleat inner face 37 and the cross beam outer face 29 and or around the cross beam outer face 29 and the cleat mounting faces surrounding apertures 33 and 34.
[0083] As detailed above, the cleat 30 comprises the end plate 32 for facilitating connection of the deck rails 24 and the cleat 30. The end plate 32 may extend in an axial plane A that is thus transverse the cleat center axis A1. The end plate 32 projects in a radial direction of the cleat
