Description

Technical Field

[0001] This disclosure generally relates to a gyratory crusher including a spider assembly for crushing rocks, stones, or other materials in a crushing chamber. More specifically, this disclosure relates to a spider assembly comprising a spider having a pair of spider arms, each spider arm having a pair of support wings attached to one of a pair of mounting sections on the outer edge of a top shell. Background Technology

[0002] A rock crusher crushes rocks, stones, or other materials within a crushing chamber formed between downwardly expanding conical mantles mounted on a main shaft that rotates within an upwardly expanding truncated conical assembly outside a concave portion of the crusher housing assembly. The conical mantles and the main shaft are circularly symmetrical about axes inclined relative to the vertical housing assembly axis. These axes intersect near the top of the rock crusher. The inclined axes are cyclically driven about the vertical axis, thus applying a gyratory motion to the main shaft and mantles. This gyratory motion causes points on the mantle surface to alternately advance toward and retreat away from a fixed concave portion. As the mantle retreats, the material to be crushed falls deeper into the chamber; when the motion reverses and the mantle advances toward the concave portion, the material is crushed within the chamber.

[0003] The star-shaped support is attached to the top of the housing assembly, forming the top of the support structure for the main shaft. The material to be crushed typically falls onto a wear-resistant star-shaped support arm guard located on the star-shaped support arms and the central hub, and then falls into the crushing chamber. The star-shaped support includes a bushing housing one end of the main shaft and a central hub. The crushing forces generated in the crushing chamber produce a very large load, a portion of which is applied to the star-shaped support. The star-shaped support must be constructed to withstand such loads to avoid having to shut down the crushing production line or the entire mine to replace and / or repair a damaged star-shaped support.

[0004] Currently, two different types of star frames are commonly used to rotatably support the main shaft on top of the top shell of a gyratory crusher. The first type of star frame is called a ring star frame or split ring star frame, as shown in the applicant's granted U.S. Patent No. 8,070,084. In this type of ring star frame, the star frame includes a central hub supported by a pair of star frame arms. The star frame arms extend outward to an outer ring that supports the entire star frame assembly on the top shell of the gyratory crusher. In some embodiments, the ring may be divided into three parts to facilitate the installation and transport of the star frame assembly. While ring star frames are durable and easy to align during installation, they are heavier and more cumbersome to install. Furthermore, the size of the ring requires a relatively large number of bolts to attach the star frame to the crusher's top shell.

[0005] The second type of star frame is called a bone-type star frame. A bone-type star frame consists of a central hub and a pair of star-shaped arms extending from the hub. Unlike a ring-type star frame, the bone-type star frame directly connects each star-shaped arm to the upper edge of the top shell. This eliminates the outer edge of the star frame, reducing its overall weight compared to a ring-type star frame. Furthermore, the elimination of the outer support ring reduces the number of bolts required, and the reduction in ring height lowers the feed height of the crusher. However, the bone-type star frame has poorer robustness and rigidity, requiring specialized equipment and grouting to secure it to the upper edge of the top shell.

[0006] The inventors of this disclosure have recognized the problems associated with ring-type star frames and bone-type star frames, and have developed this disclosure to solve and address the problems associated with each type of currently available star frame assembly. Utility Model Content

[0007] This disclosure relates to a gyratory crusher including a star-shaped frame assembly for crushing rocks, stones, or other materials in a crushing chamber. The star-shaped frame assembly includes a star-shaped frame formed according to this disclosure, the star-shaped frame including a pair of star-shaped frame arms, each star-shaped frame arm having a pair of support wings, the pair of support wings being attached to one of a pair of mounting sections on the outer edge of a top shell.

[0008] According to an exemplary embodiment of this disclosure, a gyratory crusher is provided, comprising a main frame including an upper top shell aligned about a longitudinal axis.

Each mounting section is configured to receive a lower end formed on one of the star-shaped arms and a support wing. The engagement of the mounting sections and the star-shaped arms securely holds the star-shaped frame in place on the upper edge of the upper top shell.

[0012] Each placement segment extends from the top surface of the upper edge, and the remainder of the upper edge is generally flat. This allows for a reduction in the height of the upper shell because the placement segments do not extend along the entire circumference of the upper edge. In an exemplary embodiment of this disclosure, each placement segment includes an outwardly projecting ridge and an inwardly projecting ridge spaced apart from each other by a receiving channel. Both the inwardly projecting ridge and the outwardly projecting ridge extend above the top surface of the upper edge, such that the depth of the receiving channel is defined by the height of the inwardly projecting ridge and the outwardly projecting ridge above the top surface of the upper edge.

The star-shaped frame includes a pair of star-shaped frame arms extending from a central hub. When the star-shaped frame is mounted to the upper edge of the upper top shell, the main shaft is supported in the central hub, and the pair of star-shaped frame arms are supported on and connected to the upper edge of the upper top shell.

[0016] Each star-shaped boom includes a lower end configured to connect to and be supported on an upper edge. The lower end of each star-shaped boom includes a pair of support wings, each extending in opposite directions from the lower end of the star-shaped boom. The support wings and outer ends of the star-shaped boom provide support and attachment areas for attaching the star-shaped boom to the upper edge.

[0017] Each star-shaped support arm is configured at its lower end to include a beam extending from the lower end of the star-shaped support arm. The beam is sized to be received and held within a receiving channel formed in one of the mounting sections. The beam and the receiving channel have the same curvature, such that the beam is held along its entire length. In an exemplary embodiment of this disclosure, the beam extends along the entire length of the lower end of the star-shaped support arm and along the length of a pair of support wings extending in opposite directions from the lower end.

[0018] According to one embodiment of this disclosure, each of the pair of mounting sections is formed separately from the upper top shell and attached to the upper edge of the upper top shell.

[0052] Figure 1 A gyratory crusher 10 is shown, which incorporates a star-shaped frame assembly and a top shell constructed according to the present disclosure. Figure 1 The views are included to provide a general illustration of the basic operating principle of the gyratory cone crusher and should not be construed as any limitation of this disclosure. The gyratory crusher 10 includes a vertically extending main shaft 12 extending through a main frame 14. The main shaft 12 has a longitudinal axis coinciding with the central axis of the main frame 14. A star-shaped frame 16 constructed according to this disclosure rotatably supports the main shaft 12 at its top. The crusher 10 includes an eccentric assembly rotatably supporting the bottom of the main shaft 12. The eccentric assembly is driven by a drive shaft that applies rotational and oscillating movement to the main shaft 12 via a gear assembly in a known manner.

[0053] The main shaft 12 includes a housing 18 mounted on the crushing head. The housing 18 is designed as a removable, wear-resistant component that can be removed from the crushing head of the main shaft 12 after wear. Figure 1 As shown, the main frame 14 includes an upper top shell 20 and a lower top shell 22, which are stacked one on top of the other and connected by a pair of overlapping flanges (named upper flange 24 and lower flange 26). In this way, the entire main frame 14 can be formed from separate upper top shells 20 and lower top shells 22 that can be assembled on-site, increasing the capacity for transporting gyratory crushers assembled on-site. Although the main frame 14 includes upper and lower top shells, it is conceivable that the main frame 14 could be formed to include only a single top shell for supporting the star frame 16. It is well known that the star frame 16 supports the upper end of the rotating main shaft 12 via a series of bushings located within a central hub 28 of the star frame 16. The central hub 28 is located in… Figure 1 The diagram shows a top cover 30, which is designed as a replaceable, wear-resistant component.

[0054] Now for reference Figure 2 and Figure 3The upper top shell 20 and the star-shaped frame 16 are shown separately from the rest of the main frame of the gyratory crusher 10. The upper top shell 20 includes a frame 32 formed of a durable metal material. The frame 32 extends from a top end 34 to a bottom end 36. The frame 32 includes an inner wall 38, the diameter of which decreases from the top end 34 to the bottom end 36 to guide material downward and inward within the frame 32. The frame 32 supports an outer crushing shell 40 (often also referred to as a crushing bowl), which is mounted to the inner wall 38 of the frame 32, as shown in the image. Figure 1 As best shown. The lower top shell 22 can also support the outer crushing shell. A crushing gap 42 is formed between the outer crushing shell 40 and the cover supported on the head of the main shaft 12. The size of the crushing gap decreases in the downward vertical direction to reduce the size of the material during crushing operation. When the crusher is operating, the material to be crushed is introduced into the crushing gap 42 and crushed between the cover and the outer crushing shell 40 due to the gyratory movement of the crushing head (during which the cover moves closer to the outer crushing shell 40 along the generatrix of rotation and away from the crushing shell along the opposite generatrix in the diametrical direction).

[0055] Return to reference Figure 2 and Figure 3 The star-shaped frame 16 includes a central hub 28 supported by and connected to a pair of star-shaped frame arms 44. (As...) Figure 1 As shown, the center hub 28 is centered above the crushing gap and supports the upper end of the main shaft 12. Figure 2 and Figure 3 As shown, the star-shaped arm 44 extends from the central hub 28 in the opposite direction and is designed to be spaced apart from the central hub above the top apex 34 of the upper shell 20. The open spaces on each side of the star-shaped arm 44 allow material to be introduced from the open top apex 34 of the upper shell 20 into the crushing gap. Figure 2 and Figure 3 In the illustrated embodiment, each star-shaped support arm 44 includes a pair of spaced-apart flanges 46 defining an open channel 48 between the flanges 46. The construction of the illustrated star-shaped support arm 44 is shown and described more clearly and fully in the applicant's granted U.S. Patent No. 8,070,084.

[0056] like Figure 5 As shown, each star arm 44 is designed to house a star arm guard 118 to protect the star arm 44 from material impact during operation of the gyratory crusher. The center hub 28 includes a center ring 50, which is... Figure 1 The top cover 30 shown provides a seat. During the process of material being introduced into the gyratory crusher 10 from above, the top cover 30 and the star arm guard 55 protect the star frame 16 from damage.

[0057] like Figure 2 and Figure 3As shown, the upper top shell 20 of this disclosure is designed to include an upper edge 52, which is generally flat and extends from an inner edge 54 to an outer edge 56. Therefore, the width of the upper edge 52 is defined by the difference between the diameter of the inner edge 54 and the diameter of the outer edge 56. The upper edge 52 includes a top surface 58, which is generally flat and provides a mounting surface for the star-shaped bracket 16, such as... Figure 2 and Figure 3 The comparison is shown in the image. Now refer to... Figure 3 According to this disclosure, the upper top shell 20 includes a pair of mounting sections 60 positioned along a spaced area of ​​the top surface 58 of the upper edge 52. In the illustrated embodiment, the centers of the two mounting sections 60 are spaced 180° apart from each other around the circumference of the upper edge 52. Each mounting section 60 is designed to accommodate one of the two star-shaped arms 44 to support the entire star-shaped frame 16 on the upper edge 52. Each mounting section 60 extends above the top surface 58, while the remainder of the top surface 58 is generally smooth and flat. In this way, the mounting sections 60 are included on the upper edge 52 only where radial support for the star-shaped arms 44 is required.

[0058] Now for reference Figure 7 and Figure 9 Each resettlement section 60 includes an outer ridge 62 and an inner ridge 64 spaced apart from each other to define a passageway 66. Figure 6 As can be seen, both the outer ridge 62 and the inner ridge 64 extend to a certain height above the top surface 58, which defines the depth of the receiving channel 66. The outer ridge 62 includes a curved inner engagement surface 68, while the inner ridge 64 includes a similar outer engagement surface 70. As shown, the distance between the engagement surfaces 68 and 70 defines the width of the receiving channel 66. The depth of the receiving channel 66 is defined by the distance between the upper surfaces 71 and 73 of the outer ridge 62 and the inner ridge 64 and the top surface 58 of the upper edge 52.

[0059] Return to reference Figure 9 The arc length of the outwardly convex ridge 62 is determined by... Figure 9Angle A is defined as shown. In this embodiment, angle A is approximately 33 degrees, although this angle defining the arc length can vary depending on the parameters of the gyratory crusher. It is conceivable that angle A could range between 30 and 100 degrees. The range of angle A is chosen to minimize the weight of the entire star frame while providing the necessary strength and stability along the upper edge 52 to support the star frame arm 44. The arc length of the inner ridge 64 is slightly smaller, defined by an angle slightly smaller than angle A. Although the arc length of the inner ridge 64 is shown to be smaller than that of the outer ridge 62, the arc length of the inner ridge 64 can extend to be the same as that of the outer ridge 62. During the operation of the gyratory crusher, the forces applied to the star frame are directed in both radially inward and radially outward directions, such that the length of the receiving channel 66 must be sufficient to support the inward and outward forces acting on the star frame.

[0060] like Figure 7 As shown, the placement section 60 includes a series of receiving openings 72, each sized to accommodate a connector for securing the star-shaped frame 16 to the top surface 58 of the upper edge 52. Each receiving opening 72 is located within a receiving channel 66 formed between the inner ridge 62 and the outer ridge 64. Although three receiving openings 72 are shown in the exemplary embodiment, it should be understood that additional openings 72 may be included to connect the star-shaped frame 16 to the upper edge 52.

[0061] Now for reference Figure 4 The details of the star-shaped bracket 16 will now be described in more detail. As previously mentioned, the star-shaped bracket 16 includes a central hub 28 connected to the pair of star-shaped bracket arms 44. Each star-shaped bracket arm 44 extends from an inner end 74 connected to the central hub 28 to an outer end 76. Figure 4 As shown in the top view, the width of each star-shaped support arm 44 is defined between a first side surface 78 and a second side surface 80. The first side surface 78 and the second side surface 80 are formed on opposite sides of the flange 46. The spaced-apart first side surface 78 and second side surface 80 define the total width of each star-shaped support arm 44.

[0062] like Figure 8 As shown in the bottom view, each star-shaped support arm 44 extends from an inner end 74 to an outer end 76, where the outer end 76 includes a lower end 82. The lower end 82 is integrally connected to a pair of support wings 84, each support wing 84 extending in the opposite direction from the corresponding star-shaped support arm 44. The support wings 84 are designed to provide support for the star-shaped frame 16 on the top surface 58 of the upper edge 52. The support wings 84 are integrally formed with the corresponding star-shaped support arms 44, such that the entire star-shaped frame 16 is a monolithic structure formed in a single molding step.

[0063] like Figure 7As shown in the top view, each support wing 84 includes a top surface 86 and is defined by a radially outer edge 88. The outer edge 88 has a curved shape that roughly corresponds to the curved shape of the outer edge 56 of the upper edge 52, such as... Figure 4 As best shown. The outer edge 88 defined by the pair of support wings 84 and the lower end 82 of the star-shaped arm 44 is slightly spaced inward from the outer edge 56 of the upper edge 52.

[0064] like Figure 7 As shown, each support wing 84 includes a connector opening 90. In the illustrated embodiment, each connector opening 90 is surrounded by a wall portion 92 extending above the top surface 86. The connector opening 90 is designed to align with a receiving opening 72 formed in the placement section 60, as... Figure 7 As shown by the dashed lines in the diagram. In addition to the connecting openings 90 formed in each support wing 84, a connecting opening 94 is also positioned between the pair of flanges 46 formed in the star-shaped arm 44. The central connecting opening 94 is also aligned with the central receiving opening 72 formed in the mounting section 60. The alignment of the openings formed in the star-shaped arm 44 with the openings formed in the mounting section 60 and the upper edge 52 allows three separate connectors to connect the star-shaped arm 44 to the upper edge 52 of the upper top shell 20.

[0065] Now for reference Figure 8 From a bottom view, the lower end 82 of each star-shaped arm 44 includes a pair of support wings 84 extending in opposite directions. Each support wing 84 includes a generally flat wall 96 defining a generally flat lower surface 98. The lower surface 98 extends over the entire curved outer edge 88 and along a straight inner edge 100. The flat lower surface 98 is designed to contact the upper surface 71 of the outer ridge 62 and the upper surface 73 of the inner ridge 64, respectively. This contact... Figure 6 It is best shown in the sectional view.

[0066] Each lower end 82 of the star-shaped support arm 44 includes a beam 102 extending below the lower surface 98. The beam 102 is curved and extends from a first end 104 of the first support wing to a first end 106 of the opposing support wing 84. In this way, each beam 102 extends the entire length of the combination of the support wing 84 and the lower end 82 of the star-shaped support arm. The beam 102 is integrally formed with the rest of the star-shaped support arm 16. Although in the illustrated embodiment the beam 102 extends the entire length of the support wing 84, it is conceivable that the beam 102 could be truncated and extend only a portion of the entire length of the support wing 84. In another contemplated configuration, the beam 102 could be segmented, with open breaks between the segments of the beam 102.

[0067] Each beam 102 includes an inner wall 108 and an outer wall 110, which combine to define the width of the curved beam 102. Now refer to Figure 5 and Figure 6 In the cross-sectional view, the width of the curved beam 102 between the inner wall 108 and the outer wall 110 approximately corresponds to the width of the receiving channel 66 defined between the mating surface 68 and the mating surface 70. When the star-shaped frame 16 is as Figure 5 When installed as shown, the interaction between beam 102 and receiving channel 66 restricts the radial movement of star-shaped frame 16 in the inward and outward directions. Figure 5 As shown in the cross-sectional view, the connector opening 94 formed in the lower end 82 of the star-shaped arm 44 is aligned with the receiving opening 72. In this way, the star-shaped arm 44 can be connected to the upper edge 52 of the upper top shell 20 in the area of ​​the mounting section 60 using the connector.

[0068] Now for reference Figure 6 and Figure 7 In the illustrated embodiment, each placement segment 60 is formed as an independent component attached to the top surface 58 of the upper edge 52. Each placement segment 60 includes a back plate 112, which includes an outward ridge 62 and an inward ridge 64. The back plate 112 is secured to the top surface 58 by a series of connectors, such that after the upper top shell 20 is formed, the placement segment 60 can be attached to the upper edge 52. Figure 6 As shown in the view, the inner ridge 64 includes an inclined inner surface 114 positioned toward a central opening 116 defined by the frame of the top shell 20.

[0069] Figure 5 and Figure 6 A pair of boom guards 55 supported on each star boom 44 are shown. Although the star boom 44 and boom guards 55 are shown, it should be understood that various different configurations may be used for each individual star boom 44 when operating within the scope of this disclosure.

[0070] exist Figures 2-9 In the embodiment of this disclosure shown, the mounting section 60 is shown extending above the top surface 58 on the upper edge 52 of the upper top shell 20, and the beam 102 is shown extending below the support wing 84 formed on the lower end 82 of the star-shaped arm 44. During operation of the gyratory crusher, the interaction between the beam 102 and the mounting section 60 prevents radial movement of the lower end 82 of the star-shaped arm 44. Figure 10 and Figure 11 Two alternative configurations that perform the same function in an alternative manner are shown, which will be described in detail below.

[0071] exist Figure 10In the first alternative embodiment shown, the placement section 120 is formed by a recessed receiving channel 122 extending below the top surface 58 of the upper edge 52. The recessed receiving channel 122 is defined by an outer ridge 124 and an inner ridge 126, both extending below the top surface 58. The recessed receiving channel 122 is sized to accommodate a beam 102 formed on the lower end 82 of the star-shaped support arm 44. Figure 10 In the embodiment shown, the placement section 120 will be recessed from the top surface 58, and it is not necessary to... Figures 2-9 As in the illustrated embodiment, a separate component is added to the top surface 58. The placement section 120 will extend within the same angular range as described above and will prevent radial outward movement of the star-shaped arm 44 during operation.

[0072] Figure 11 A second alternative embodiment is shown, in which the beam on the lower end 82 of the star-shaped support arm 44 is removed and replaced by a recessed receiving channel 130 extending inward from the lower surface 132 on the lowest part of the star-shaped support arm 44. The recessed receiving channel 130 is defined by an outer ridge 134 and an inner ridge 136. In an exemplary embodiment, the recessed receiving channel 130 extends along the entire length of the support wing formed on the lower end 82 of the star-shaped support arm 44. However, in an alternative embodiment, the recessed receiving channel 130 may be formed along less than the entire length of the support wing. The dimensions of the recessed receiving channel 130 formed on the lower end 82 of the star-shaped support arm 44 are configured to closely correspond in size and depth to the beam 138 formed on the top surface 58 of the upper edge 52. The beam 138 extends above the top surface 58 and is designed to be received within the recessed receiving channel 130 when the star-shaped support is mounted on the upper top shell 20. Figure 10 As in the previous embodiment, the placement section 140 extends within the same angular range as described above and prevents radial outward movement of the star-shaped arm 44 during operation.

[0073] In the three embodiments shown, the placement section is formed along a limited area on the upper edge 52 of the upper top shell 20, and the remaining area of ​​the upper edge 52 is generally flat and without any elements. The flatness of the remaining portion of the upper edge 52, excluding the placement section, reduces the feed height of the star-shaped frame. The illustrated embodiments include receiving channels and beams located on the lower end of the star-shaped frame arm and the top surface of the upper edge. When operating within the scope of this disclosure, the positions of the corresponding receiving channels and beams can be interchanged between the star-shaped frame arm and the upper edge.

[0074] This written description uses examples to disclose the present invention, including the best mode, and also enables any person skilled in the art to make and use the present invention. The patent scope of the present invention is defined by the claims, but may include other examples that would occur to a person skilled in the art. Such other examples should also fall within the scope of the claims if their structural elements are not different from the wording of the claims, or if such other examples include equivalent structural elements that are not substantially different from the wording of the claims.
