Description

Technical Field

[0001] This disclosure generally relates to wedge-shaped attachments for the outer wear parts of a cone crusher. Background Technology

[0002] This section provides useful background information, but does not acknowledge that any techniques described herein represent prior art.

[0003] Rocks and other mineral materials can be crushed between the inner and outer wear parts of a cone crusher. The inner wear part is conical and rests on a supporting cone. The outer wear part can also be generally conical. The outer wear part is supported by a cup-shaped component. The cup-shaped component can be height-adjustable, for example, via a threaded adjustment.

[0004] The outer wear component faces significant forces, which, if not properly attached, can cause it to move uncontrollably. Typically, both the cup-shaped component and the outer wear component comprise a uniformly conical body. The operation of a cone crusher causes the inner wear component to rotate, directing the crushing force in different directions. Any gap between the outer wear component and the cup-shaped component will significantly abrade both. Even with a tight fit, the contact area between the outer wear component and the cup-shaped component will wear. The cup-shaped component can be made of a harder or more wear-resistant material, allowing wear to occur entirely or primarily within the outer wear component. However, due to wear, the outer wear component may become loosely fitted, leading to accelerated wear. A wedge-shaped attachment for the outer wear component can appropriately allow for secure fastening of the outer wear component to the cup-shaped component.

[0005] The mineral crusher is subjected to extremely harsh conditions due to the excessive presence of small rock particles, sand, and dust. Furthermore, the tightening force of the wedge attachment is extremely high. The wedge can exist as a opposing surface between the bottom surface of the ear or edge of the outer wear part and the top surface of the periphery of the bowl-shaped part. The wedge tends to become tightly stuck. Moreover, if the outer wear part and the bowl-shaped part are only attached by the wedge, the bowl-shaped part may slide uncontrollably along or with the wedge. When sliding along the wedge, the wedge may become over-tightened. When sliding with the wedge, the outer wear part may begin to rotate with the inner wear part, worsening the crushing results and causing rapid wear on the bottom of the wedge and the opposing surface of the bowl-shaped part. Summary of the Invention

[0006] The appended claims define the scope of protection. Any examples and technical descriptions of devices, products, and / or methods not covered by the claims in the specification and / or drawings are not presented as embodiments of the invention, but rather as background or examples for understanding the invention.

[0007] According to a first example aspect, a wedge attachment system is provided for attaching an outer wear component of a cone crusher, the system comprising: The arc-shaped wedge is configured to support the lip of the outer wear component against the edge of the bowl-shaped component of the cone crusher; The wedge also includes a lateral convex heel, which is configured to conform with the lateral concave shoulder of the bowl-shaped member. The wedge also includes a tangentially inclined shelf configured to engage with the bottom surface of the lip of the outer wear member, such that the heel has a tangentially increased thickness defined by a material present between the bottom surface of the heel and the top surface of the shelf. The wedge-shaped component also includes a ridge; The ridge includes a concave front end, which is an upright portion configured to face the radial side of the lip; and The wedge-shaped piece is capable of tangential movement, the changing portion of the shelf is located below the lip, and the front changing portion faces the radial side of the lip.

[0008] The lip can be present on the outer surface of the outer wear part. The lip can be present at the top of the outer wear part. When the cone crusher is in operation, the lip can be present within 5 mm, 10 mm, or 20 mm of the highest part of the outer wear part.

[0009] According to a second example aspect, a wedge-shaped member is provided for attaching to an outer wear component of a cone crusher, the wedge-shaped member comprising: An arc-shaped body is configured to support the lip of the outer wear component against the edge of the bowl-shaped part of the cone crusher; the arc-shaped body includes: The lateral convex heel is configured to conform to the lateral concave shoulder of the bowl-shaped part; A tangentially inclined shelf is configured to engage with the bottom surface of the lip of an outer wear member, such that the heel has a tangentially increased thickness, the increased thickness being defined by a material present between the bottom surface of the heel and the top surface of the shelf. The ridge includes a concave front end, which is an upright portion configured to face the radial side of the lip; and The wedge-shaped piece is capable of tangential movement, the changing portion of the shelf is located below the lip, and the front changing portion faces the radial side of the lip.

[0010] The ridge can be adjacent to the heel. The ridge and heel can be formed integrally. The entire wedge can be formed integrally.

[0011] When viewed from above, the ridge can have a double-concave shape. This double-concave shape increases the strength of the ridge when the wedge is pressed into or out of position through its end faces. The double-concave shape can define two facing arrowhead shapes configured to transfer force through the ridge to the heel when attaching or detaching the wedge, while avoiding an increase in mass. Reducing the mass of the wedge simplifies manual operation.

[0012] The ridge can easily extend radially away from the outer wear parts to allow the use of hydraulic cylinders.

[0013] The wedge may have a wedge angle. The wedge angle may be at least 1 degree, 2 degrees, or 3 degrees to provide sufficient elevation (height) without an excessively long wedge, which would add undue weight. The wedge angle may be up to 4 degrees, 5 degrees, or 6 degrees to reduce the tendency of the wedge to slip and the forces generated on any components that limit the slippage of the wedge during operation of the cone crusher.

[0014] Wedges can be made of steel. Wedges can be made by precision casting. Wedges can be made by lost-wax casting.

[0015] The edge can face the outer wear part.

[0016] The ridge may be included on the rear side opposite the front. The rear may be convex, such that the ridge is thinner in the lateral direction at the center than near the ends of the ridge. The convex shape of the rear reduces the weight of the wedge. The reduced weight of the wedge helps to release the wedge by the hammer by reducing the resulting inertia.

[0017] Wedges can have rounded edges between the ridge and the shelf. Rounding the edges reduces stress concentration and simplifies the manufacturing of the wedges.

[0018] The shelf can open from its lower end, allowing the wedge to slide beneath the lip. The shelf may have a closed end at the end of the wedge opposite the lower end of the shelf. This closed end may form a stop. The stop may include a stop face existing in a radial plane relative to the central axis of the cup-shaped member. The stop face may have an acute angle relative to the shelf. The wedge may have a rounded edge between the stop face and the shelf.

[0019] The wedge-shaped part may have a rounded edge between the ridge and the closed end.

[0020] During the operation of the cone crusher, the front can have a circular shape with a constant distance from the central axis of the bowl-shaped part.

[0021] The bowl-shaped component can define a conical receiving space for the outer wear component. The conical receiving space can have a central axis.

[0022] The heel may have a front side that is at a constant distance from the central axis.

[0023] The heel may have a rear side at a constant distance from the central axis. The rear side of the heel may be configured to face the shoulder of the cup-shaped member. The shoulder of the cup-shaped member may have a constant distance from the central axis.

[0024] The heel can be higher than the shoulder, allowing the wedge to extend below the shoulder. The back of the spine can extend beyond the shoulder, meaning the distance between the back and the central axis can be greater than the distance between the shoulder and the central axis.

[0025] All edges of the wedge can be rounded.

[0026] The system may also include multiple wedge-shaped components.

[0027] The system may also include an intermediate support member. The intermediate support member may be releasably attached to the top surface of the cup-shaped member, for example, by bolts or nuts.

[0028] The intermediate support member may include a first tangential fastening member, such as a bolt. The second tangential fastening member may be configured to hold the wedge in place.

[0029] The intermediate support member may also include a second tangential fastening member, such as a bolt. The second tangential fastening member may be configured to abut against a radial protrusion of the outer wear member to prevent rotation of the outer wear member when the wedge is pressed into place.

[0030] The system may also include one or more wedge-shaped washers configured to be located below the wedge to change the height position of the wedge. The washers may be screwed to the bottom of the wedge.

[0031] The first omnidirectional fastening member can be set to a first height and a second height. The first omnidirectional fastening member can be set to one or more different heights between the first height and the second height. The first omnidirectional fastening member can be set to one or more different heights according to the height position of the wedge.

[0032] The second tangential fastening member can be configured with a third and a fourth height. The second tangential fastening member can be configured with one or more different heights between the third and fourth heights. The second tangential fastening member can be configured with one or more different heights based on the height position of the outer wear component.

[0033] The intermediate support component may include a substrate.

[0034] The intermediate support member may also include a first upright member attached to one end of the substrate. The first upright member may include an opening for receiving the first tangential fastening member.

[0035] The intermediate support member may also include a second upright member attached to one end of the substrate. The second upright member may include an opening for receiving the second tangential fastening member.

[0036] The system may also include multiple intermediate support members. The system may also include one intermediate support member for each of at least two wedges.

[0037] The system may also include an actuator support. The actuator support may be configured to prevent excessive rotation of the outer wear component. The actuator support may be configured to provide a backing surface for the hydraulic actuator when used to slide the wedge out.

[0038] The actuator support may include a reaction surface configured to face the wedge. The reaction surface may be at a normal angle to the force received from the hydraulic actuator upon release of the wedge. Alternatively, the reaction surface may be at an angle greater than 90 degrees to the force received from the hydraulic actuator upon release of the wedge, such that the reaction surface generates a radial force component in the actuator support toward the outward-facing wear component.

[0039] The actuator support can be configured to prevent excessive rotation of the outer wear component using a first anti-rotation shape, which mates with a second anti-rotation shape on the outer surface of the outer wear component. The first anti-rotation shape can be complementary to the second anti-rotation shape. The first anti-rotation shape can include either a recess or a protrusion. The second anti-rotation shape can include either a protrusion or a recess. A protrusion can be a vertical ridge.

[0040] The actuator support may include a handle and / or a lifting ring.

[0041] The actuator support may include a top plate. The top plate may be shaped to prevent excessive rotation of the wear components. The actuator support may include end plates at each end of the actuator support. The end plates may be perpendicular to the top plate. The actuator support may include sidewalls configured to extend from the outer edge of one end plate to the outer edge of the other end plate.

[0042] The actuator support can be configured to provide an attachment backing. The attachment backing can be configured to face the tail end of the wedge when the wedge is inserted between the cup-shaped member and the outer wear member. The attachment backing can be configured to support the hydraulic actuator when the wedge is pressed in.

[0043] The actuator support can be movable to allow for the removal or attachment of wedges one by one.

[0044] The system may further include an actuator support constraint. The actuator support constraint may be integrally formed from a cup-shaped member. The actuator support constraint may be screwed to the cup-shaped member. The actuator support constraint may be welded to the cup-shaped member. The actuator support constraint may be configured to form a locking actuator support. The actuator support constraint may be configured to resist forces arising during the attachment of the wedge to form a locking actuator support. The actuator support constraint may be configured to resist forces arising during the disassembly of the wedge to form a locking actuator support.

[0045] According to the third example aspect, a cone crusher is provided, comprising: The wedge attachment system of the first example aspect; Bowl-shaped parts; and Wear on the outer side.

[0046] According to the fourth example aspect, a mobile mineral material processing device is provided, comprising: The cone crusher in the second example aspect; and The processing equipment frame is used to support the cone crusher.

[0047] Mineral material processing equipment may also include self-propelled devices for moving the mineral material processing equipment, such as one or more wheels, tracks and / or outriggers.

[0048] According to the fifth example aspect, a wedge attachment method is provided, comprising: The lip of the outer wear component of the cone crusher is supported by an arc-shaped wedge to the edge of the bowl-shaped component of the cone crusher; The lateral convex heel of the arc-shaped wedge conforms to the lateral concave shoulder of the bowl-shaped part; By joining the arc-shaped wedge to the bottom surface of the lip of the outer wear member with a tangentially inclined shelf, the heel has a tangentially increased thickness, which is defined by the material present between the bottom surface of the heel and the top surface of the shelf. The ridge is provided by an arc-shaped wedge; The concave front of the ridge faces the radial side of the lip; and The wedge is moved tangentially, the modified portion of the shelf is located below the lip, and the front modified portion faces the radial side of the lip.

[0049] Different non-constraintive example aspects and embodiments have been described above. The foregoing embodiments are only used to explain selected aspects or steps that can be used in different implementations. Some embodiments may be presented with reference only to certain example aspects. It should be understood that the corresponding embodiments can also be applied to other example aspects.

Detailed Implementation

[0051] In the following description, the same reference numerals denote the same elements or steps.

[0052] Figure 1 It shows the result of Figures 2 to 6 A top view of a wedge attachment system 100 for a cone crusher, further shown, is included in the system: The arc-shaped wedge 110 is configured to support the lip 122 of the outer wear part 120 of the cone crusher onto the edge 132 of the bowl-shaped part 130 of the cone crusher. The wedge 110 also includes a lateral convex heel 210, which is configured to correspond to the lateral concave shoulder 134 of the bowl-shaped member; The wedge 110 also includes a tangentially inclined shelf configured to engage with the bottom surface of the lip 122 of the outer wear member, such that the heel has a tangentially increased thickness defined by the material present between the bottom surface 122b of the heel and the top surface 220t of the shelf. The wedge 110 also includes a ridge 230; The ridge 230 includes a concave front surface 230f, which is an upright portion configured to face the radial side 122r of the lip; and The wedge 110 is tangentially movable, the modified portion of the shelf 220 is located below the lip 122, and the modified portion of the front 230f of the ridge faces the radial side 122r of the lip.

[0053] Figure 1 The edge 132 is circular. The center of the edge 132 defines a portion of the central axis 140 of the bowl-shaped member 130. The central axis 140 continues further downward within the bowl-shaped member 130.

[0054] Figure 3 A lip 122 is shown on the outer surface of the outer wear member. In an alternative example embodiment, the lip is located at the top of the outer wear member. In an example embodiment, when the cone crusher is in operation, the lip is located within 5 mm, 10 mm, or 20 mm of the highest portion of the outer wear member.

[0055] like Figure 2 As shown, the wedge 110 has a wedge angle that raises the surface supported by the shelf 220, here the lip 122 (on the top surface 220t of the shelf, see...). Figure 3 In an example embodiment, the wedge angle is preferably at least 1 degree, more preferably at least 2 degrees, or even more preferably at least 3 degrees, to provide sufficient lift without an excessively long wedge that would unduly add weight. In an example embodiment, the wedge angle is preferably at most 4 degrees, more preferably at most 5 degrees, or even more preferably at most 6 degrees, to reduce the tendency of the wedge 110 to slip and the forces generated on any components that limit the slippage of the wedge 110 during operation of the cone crusher.

[0056] In an example embodiment, the wedge 110 is made of steel. In an example embodiment, the wedge 110 is made by precision casting. In an example embodiment, the wedge 110 is made by lost-wax casting.

[0057] exist Figure 1 In the middle, the outer wear component 120 is mainly located inside the cup-shaped component 130. For example... Figure 3 As can be seen, the top of the outer wear member 120 extends above the adjacent structure of the bowl-shaped member 130. Figure 3The edge 132 of the bowl-shaped member facing outwards towards the wear component is also shown for supporting the support base of the wedge-shaped member 110. In an example embodiment, the edge 132 includes an annular single-walled groove or support ring 312 for carrying the wedge-shaped member 110. Figure 3 A shim 320 is also shown, which is attached to the bottom of the wedge 110 to increase the elevation of the outer wear component. Since the wear of the outer wear component requires a greater elevation than that achievable by tightening the wedge 110, this stepped further increase may be necessary.

[0058] Let's return to wedge 110, as... Figure 2 As shown. In an example embodiment, the ridge 230 includes a rear 230r on the side opposite to the front 230f. Figure 3 The rear 230r is shown as convex, such that the ridge is thinner in the lateral direction at the central portion (e.g., within five percent of the length of the wedge 110 from its longitudinal center) than near the ends of the ridge. Advantageously, forming the convex shape of the rear reduces the weight of the wedge 110. The weight reduction of the wedge 110 can help reduce the overall mass of the cone crusher and / or help the wedge 110 be released by the hammer by reducing the resulting inertia, thereby reducing the impact of the hammer impact.

[0059] exist Figure 2 In this design, the wedge 110 has a rounded edge between its ridge and the shelf. The rounded edge reduces stress concentration and simplifies the manufacturing of the wedge 110. Figure 2 Other rounded edges at the ends of the shelf and other rounded edges at other edges are also shown, optionally including other rounded edges at all edges, such as the additional rounded edge between the radially outward surface of the heel and the bottom surface of the ridge. As an alternative to rounding, one or more edges may be beveled.

[0060] The shelf opens from its lower end (i.e., front end), allowing the wedge 110 to slide beneath a lip. The shelf has a closed end at the tail end of the wedge 110, opposite the front end of the shelf. The closed end forms a stop. The stop includes a stop surface existing in a radial plane relative to the central axis 140. The stop surface has an acute angle relative to the shelf. The wedge 110 has a rounded edge between the stop surface and the shelf.

[0061] In an example embodiment, during operation of the cone crusher, the front has a circular shape at a constant distance from the central axis 140.

[0062] exist Figure 1 In the middle, the bowl-shaped part defines a conical receiving space for the outer wear part 120.

[0063] In the example embodiment, the heel portion 210 has a front side that is at a constant distance from the central axis 140. Therefore, the heel portion can be aligned with the edge of the edge 132, for example, as... Figure 3 As shown.

[0064] In an example embodiment, the heel portion 210 has a rear side 210r at a constant distance from the central axis 140. The rear side of the heel portion 210 is configured to face the shoulder portion 134 of the bowl-shaped member. The shoulder portion 134 is at a constant distance from the central axis 140. The heel portion 210 is preferably configured to travel along the edge 132 during fastening, such that the heel portion 210 remains aligned with the edge 132.

[0065] The heel portion 210 is higher than the shoulder portion 134, allowing the wedge-shaped member 110 to extend below the shoulder portion 134. In the example embodiment, the rear end 230r of the ridge portion 230 extends beyond the shoulder portion 134, that is, the distance between the rear end 230r and the central axis 140 is greater than the distance between the shoulder portion 134 and the central axis 140.

[0066] Most or all of the edges of the wedge 110 are preferably rounded to reduce stress concentration and / or to facilitate the installation and placement of the wedge 110 and / or to simplify the manufacture of the wedge 110.

[0067] Preferably, the system includes a plurality of wedges 110, such as three or more. Three wedges 110 facilitate the stable fastening of the outer wear component 120 to the cup-shaped component 130 while avoiding redundancy. Alternatively, more than three wedges 110 may be used to reduce the force at each wedge 110 attachment point and increase structural redundancy to mitigate the risk of mechanical failure.

[0068] In an example embodiment, system 100 also includes an intermediate support member 150. For example, after the wedge 110 is installed in place, the intermediate support member can be releasably attached to the top surface of the bowl-shaped member, for example, by bolts or nuts.

[0069] In an example embodiment, the intermediate support member 150 includes a first tangential fastening member, such as a bolt 410. The first tangential fastening member is configured to hold the wedge 110 in place. Figure 4 The intermediate support member also includes a second tangential fastening member, here another bolt 410'. For reference, the reference numerals are slightly different. The second tangential fastening member 410' is configured to abut against the radial protrusion 170 or lug of the outer wear member 120 to prevent rotation of the outer wear member 120 when the wedge 110 is pressed into place (i.e., below the lip 122). Advantageously, the second tangential fastening member 410' can prevent or reduce the risk of the outer wear member 120 rotating uncontrollably to an unsuitable fastening angle on the lower part of the shelf 220 of the wedge 110.

[0070] In an example embodiment, system 100 further includes one or more wedge-shaped pads 320 configured to be present below wedge 110 to change the height position of wedge 110. The pads 320 may be screwed to the bottom of wedge 110.

[0071] In an example embodiment, the first tangential fastening member 410 can be configured with a first height and a second height. In an example embodiment, the first tangential fastening member 410 can be configured with one or more different heights between the first height and the second height. In an example embodiment, the first tangential fastening member 410 can be configured with one or more different heights depending on the height position of the wedge member 110. Figure 4 In this design, the height of the first tangential fastening member 410 is adjustable by providing a vertical groove in which the first tangential fastening member 410 can be properly aligned with the opposing surface of the wedge member 110.

[0072] In an example embodiment, the second tangential fastening member 410' can be configured with a third height and a fourth height. In an example embodiment, the second tangential fastening member 410' can be configured with one or more different heights between the third height and the fourth height. In an example embodiment, the second tangential fastening member 410' can be configured with one or more different heights depending on the height position of the outer wear member 120. Figure 4 In this design, the height of the second tangential fastening member 410' is adjustable by providing a vertical groove in which the second tangential fastening member 410' can be properly aligned with the opposing surface of the ear of the outer wear member 120.

[0073] In an example embodiment, the intermediate support member 150 includes a base plate 430. In an example embodiment, the base plate 430 is bent to conform to the outer wear member 120.

[0074] In an example embodiment, the intermediate support member 150 further includes a first upright member 440 attached to one end of the substrate 430. In an example embodiment, the first upright member 440 includes an opening for receiving a first tangential fastening member 410.

[0075] In an example embodiment, the intermediate support member 150 further includes a second upright member 440' attached to one end of the substrate 430. In an example embodiment, the second upright member 440' includes an opening for receiving a second tangential fastening member 410'.

[0076] In an example embodiment, system 100 further includes a plurality of intermediate support members 150. In an example embodiment, system 100 also includes one intermediate support member 150 for each of at least two wedges 110.

[0077] In an example embodiment, system 100 also includes actuator support 500, such as Figure 5 As shown. The actuator support 500 is configured to prevent uncontrolled rotation of the outer wear member 120. The actuator support 500 is configured to provide a backing surface for the hydraulic actuator (not shown) when used to slide the wedge 110 out.

[0078] The actuator support 500 includes a reaction surface configured to face the cup-shaped member. The reaction surface forms a normal angle with respect to the force received from the hydraulic actuator upon release of the wedge 110. Alternatively, the reaction surface forms an angle greater than 90 degrees with respect to the force received from the hydraulic actuator upon release of the wedge 110, such that the reaction surface generates a radial force component in the actuator support 500 toward the outward wear member 120.

[0079] The actuator support 500 is configured to prevent excessive rotation of the outer wear member 120 using a first anti-rotation shape, which mates with a second anti-rotation shape on the outer surface of the outer wear member 120. The first and second anti-rotation shapes are complementary. The first anti-rotation shape includes either a recess or a protrusion. The second anti-rotation shape includes either a protrusion or a recess. The protrusion is a vertical ridge.

[0080] The actuator support 500 includes a handle 540.

[0081] The actuator support 500 includes a top plate 510. The top plate is shaped to prevent excessive rotation of the wear components. The actuator support 500 includes end plates 520 at each end of the actuator support 500. In an example embodiment, the end plates 520 are perpendicular to the top plate 510. The actuator support 500 includes sidewalls 530 configured to extend from the outer edge of one end plate 520 to the outer edge of the other end plate 520.

[0082] In an example embodiment, the actuator support 500 is configured to provide an attachment backing, such as Figure 6 As shown. The attachment backing is configured to face the tail end of the wedge 110 when the wedge 110 is inserted between the cup-shaped member and the outer wear member 120. The attachment backing is configured to support the hydraulic actuator 610 (e.g., a hydraulic cylinder or hydraulic jack) when the wedge 110 is pressed in.

[0083] The actuator support 500 is movable and is used to detach or attach the wedges 110 one after another.

[0084] Figure 1 , Figure 6 and Figure 7 Actuator support constraint 160 is also shown, which is integrally formed from a cup-shaped member, for example, by forming a recess of a suitable shape as shown in these figures. The actuator support constraint 160 substantially restricts the movement of the actuator support when used to retract the hydraulic actuator. In an example embodiment (not shown), the actuator support constraint is screwed to the cup-shaped member. In an example embodiment (not shown), the actuator support constraint is welded to the cup-shaped member. In the example embodiment, for example, as... Figure 1 , Figure 6 and Figure 7 As shown, the actuator support constraint is configured to form a locking actuator support 500.

[0085] In the Figure 7 In the illustrated example embodiment, the actuator support constraint 160 is configured to form a locking actuator support 500 against forces generated when the wedge 110 is attached. In the illustrated example embodiment, the actuator support constraint 160 is configured to form a locking actuator support 500 against forces generated when the wedge 110 is dismounted.

[0086] Figure 8 A flowchart illustrating wedge attachment according to an example embodiment is shown, including: 810. The lip of the outer wear part 120 of the cone crusher is supported on the edge of the bowl-shaped part of the cone crusher by means of an arc-shaped wedge.

[0087] 820. The lateral convex heel of the arc-shaped wedge conforms to the lateral concave shoulder of the bowl-shaped part.

[0088] 830. The arcuate wedge is joined to the bottom surface of the lip of the outer wear member 120 by a tangentially inclined shelf, such that the heel has a tangentially increased thickness, which is defined by the material present between the bottom surface of the heel and the top surface of the shelf.

[0089] 840. A ridge is provided by an arc-shaped wedge.
