Abstract
Description
Technical Field
[0001] The disclosure of the present application (hereinafter referred to as the present disclosure) generally relates to a wedge attachment for an outer wear part of a cone crusher. Background
[0002] It should be noted that this section describes useful background information, but it is not admitted that the techniques described herein represent the state of the art.
[0003] Rocks and other mineral materials are crushed between the inner wear part and the outer wear part of a cone crusher. The inner wear part is conical and rests on a support cone. The outer wear part is generally conical. The outer wear part is supported by a bowl. The bowl can be adjusted in height, for example, by screw adjustment.
[0004] If the outer wear part is not properly attached, it is exposed to large forces that can cause uncontrollable movement. Usually, the bowl and the outer wear part are each composed of a uniform cone. The cone crusher operates such that the inner wear part rotates to direct the crushing force in various directions. If there is play between the outer wear part and the bowl, the wear of both parts progresses significantly. Even in a close contact state, the contact part between the outer wear part and the bowl wears. Since the bowl is made of a hard or highly wear-resistant material, almost all wear occurs in the outer wear part. However, wear may loosen the close contact of the outer wear part and accelerate wear. The wedge attachment of the outer wear part is suitable for clamping the outer wear part against the bowl.
[0005] Mineral crushers are exposed to extremely harsh conditions, containing a large amount of fine rock particles, sand, and dust. Furthermore, the clamping force of the wedge attachment is extremely high. The wedge can be positioned as an opposing surface between the bottom surface of the ear or rim of the outer abrasive part and the top surface of the rim of the bowl. The wedge tends to become tightly jammed. Also, if the outer abrasive part and the bowl are secured only by the wedge, the bowl may slide uncontrollably along or with the wedge. Sliding along the wedge causes the wedge to become excessively clamped. Sliding with the wedge causes the outer abrasive part to begin rotating with the inner abrasive part, worsening the crushing results and causing rapid wear between the bottom of the wedge and the opposing surface of the bowl. Summary
[0006] The attached claims define the scope of protection. Any examples or technical descriptions of apparatus, products, and / or methods in this specification and / or drawings that are not covered by the claims are presented not as embodiments of the invention, but as background art or examples that are helpful to understanding the invention.
[0007] According to a first exemplary aspect, a wedge attachment system for mounting the outer wear component of a cone crusher is provided. This system is The cone crusher is provided with an arc-shaped wedge configured to support the lip of the outer wear part on the rim of the bowl, The wedge is provided with a heel portion that protrudes laterally, and the heel portion is configured to fit into the laterally recessed shoulder portion of the bowl. The wedge further comprises a tangentially inclined shelf portion configured to engage with the bottom surface of the lip of the outer wear part, and the heel portion has a tangentially increasing thickness defined by the material present between the bottom surface of the heel portion and the top surface of the shelf portion. The aforementioned wedge further includes a ridge, The ridge is an upright portion configured to face the radial side surface of the lip, and has an inwardly curved front surface. The wedge is tangentially movable, together with the changing portion of the shelf below the lip and the changing portion of the front surface of the ridge facing the radial side surface of the lip.
[0008] The lip may be located on the outer surface of the outer wear component. The lip may be located on the top of the outer wear component. During operation of the cone crusher, the lip may be located within 5 mm, 10 mm, or 20 mm from the highest point of the outer wear component.
[0009] According to a second exemplary aspect, a wedge is provided for mounting the outer wear component of a cone crusher. This wedge is The cone crusher comprises an arc-shaped body configured to support the lip of the outer wear part on the rim of the bowl, and the body is, A laterally protruding heel portion is configured to fit the laterally recessed shoulder portion of the bowl, A shelf portion inclined in the tangential direction, configured to engage with the bottom surface of the lip of the outer wear part, The heel portion has a thickness that increases tangentially, defined by the material present between the bottom surface of the heel portion and the top surface of the shelf portion, and the main body further comprises, It comprises a ridge having an inwardly curved front surface, the inwardly curved front surface being an upright portion configured to face the radial side surface of the lip, The wedge is tangentially movable, together with the changing portion of the shelf below the lip and the changing portion of the front surface of the ridge facing the radial side surface of the lip.
[0010] The ridge may be adjacent to the heel portion. The ridge and the heel portion may be integrally formed. The entire wedge may be integrally formed.
[0011] The ridge may have a shape that is concave on both sides when viewed from above. This double-concave shape can increase the strength of the ridge when pushing the wedge into a predetermined position from the end face of the ridge or pulling it out there. The double-concave shape can define two opposing arrow shapes that transmit force to the heel portion via the ridge when attaching or detaching the wedge, while avoiding an increase in mass. Reducing the mass of the wedge lowers the difficulty of handling the wedge manually.
[0012] The ridge may extend radially away from the outer wear component to allow the use of a hydraulic ram.
[0013] The wedge may have a wedge angle. The wedge angle may be at least 1, 2, or 3 degrees in order to ensure sufficient inclination while preventing the wedge from becoming too long to excessively increase its weight. The wedge angle may be a maximum of 4, 5, or 6 degrees in order to prevent the wedge from slipping during the operation of the cone crusher and to reduce the force applied to the member in an attempt to prevent the wedge from slipping during the operation of the cone crusher.
[0014] The wedge may be made of steel. The wedge may be manufactured by precision casting. The wedge may be manufactured by lost-wax casting.
[0015] The rim may face the outer wear part.
[0016] The ridge may have a front surface and a rear surface on the opposite side. The rear surface may be convex such that the ridge is thinner laterally in the center than near the ends. The convex shape of the rear surface can reduce the weight of the wedge. Reducing the weight of the wedge helps to remove the wedge with a hammer by reducing the resulting inertia.
[0017] The wedge may have a rounded edge between the ridge and the shelf. The rounded edge reduces stress concentration and can lower the difficulty of manufacturing the wedge.
[0018] The shelf portion may be open from the lower end of the shelf portion so that the wedge can slide under the lip. The shelf portion may have a closed end at the end opposite to the lower end of the shelf portion. The closed end may form a stopper. The stopper may have a stopper surface located radially with respect to the central axis of the bowl. The stopper surface may form an acute angle with respect to the shelf portion. The wedge may have a rounded edge between the stopper surface and the shelf portion.
[0019] The wedge may have a rounded edge between the ridge and the closed end.
[0020] The front surface may have a circular shape with a constant distance from the central axis of the bowl during the operation of the cone crusher.
[0021] The bowl may define a conical receiving space for the outer wear part. The conical receiving space may have a central axis.
[0022] The heel portion may have a front surface that maintains a constant distance from the central axis.

[0024] The heel portion may be higher than the shoulder so that the wedge can extend under the shoulder. The rear surface of the ridge may extend beyond the shoulder. That is, the rear surface may be farther from the central axis than the shoulder.
[0025] All edges of the wedge may be rounded.
[0026] The system may include a plurality of wedges.

[0028] The intermediate support member may include a first tangential tightening member such as a bolt. The first tangential tightening member may be configured to hold the wedge in a predetermined position.
[0029] The intermediate support member may further include a second tangential tightening member such as a bolt. The second tangential tightening member may be configured to abut against a radial protrusion of the outer wear part so as to prevent rotation of the outer wear part when the wedge is pushed into a predetermined position. The system may further include one or more wedge shims configured to be disposed under the wedge to change the height position of the wedge. The wedge shim may be fixed to the bottom of the wedge with bolts.
[0030] The first tangential tightening member may be fixed at a first height and a second height. The first tangential tightening member may be fixed at one or more different heights between the first height and the second height.

The resistance surface may be at an angle perpendicular to the force received from the hydraulic actuator when the wedge is removed. Alternatively, the resistance surface may be at an angle greater than 90 degrees to the force received from the hydraulic actuator when the wedge is removed. This causes the resistance surface to generate a radial force component in the direction of the outer wear component at the actuator support portion.
[0038] The actuator support portion may be configured to prevent excessive rotation of the outer wear part by a first anti-rotation shape that cooperates with a second anti-rotation shape on the surface of the outer wear part.

[Figure 7] This is a partial top view showing the operating state of the actuator support for removing the wedge. [Figure 8] A flowchart of wedge mounting in one exemplary embodiment is shown. Detailed description
[0050] In the following description, similar symbols indicate similar elements or steps.
[0051] Figure 1 shows a plan view of the wedge attachment system 100 for a cone crusher, which will be further explained in Figures 2 to 6. This system is The cone crusher comprises an arc-shaped wedge 110 configured to support the lip 122 of the outer wear part 120 of the cone crusher on the rim 132 of the bowl 130 of the cone crusher; The wedge 110 has a laterally protruding heel portion 210, which is configured to fit into the laterally recessed shoulder portion 134 of the bowl; The wedge 110 further comprises a tangentially inclined shelf portion configured to engage with the bottom surface of the lip 122 of the outer wear part, and the heel portion has a tangentially increasing thickness defined by the material present between the bottom surface of the heel portion and the top surface 220t of the shelf portion; The wedge 110 further includes a ridge 230; The ridge 230 has an inwardly curved front surface 230f, which is an upright portion configured to face the radial side surface 122r of the lip; The wedge 110 is tangentially movable, along with the changing portion of the shelf 220 below the lip 122 and the changing portion of the front surface 230f of the ridge facing the radial side 122r of the lip.
[0052] The rim 132 in Figure 1 is circular. The center of the rim 132 defines a portion of the central axis 140 of the bowl 130. The central axis 140 continues further downward within the bowl 130.
[0053] Figure 3 shows the lip 122 located on the outer surface of the outer wear component. In some embodiments, the lip is located at the top of the outer wear component. In some embodiments, during the operation of the cone crusher, the lip is located within 5 mm, 10 mm, or 20 mm from the highest point of the outer wear component.
[0054] As shown in Figures 2 and 3, the wedge 110 has a wedge angle, and the shelf portion 220 causes the wedge 110 to tilt its support surface (here, the lip 122) (on the upper surface 220t of the shelf portion) at this wedge angle. In some embodiments, the wedge angle is preferably at least 1 degree, more preferably at least 2 degrees, and even more preferably at least 3 degrees. This is to ensure sufficient tilt while preventing the wedge from becoming too long and excessively increasing the weight. In some embodiments, it is desirable that the wedge angle be at most 4 degrees, more preferably at most 5 degrees, and even more preferably at most 6 degrees. This is to suppress the wedge 110 from slipping during the operation of the cone crusher, and also to reduce the force applied to the member in an attempt to suppress the slipping of the wedge 110 during the operation of the cone crusher.
[0055] In some embodiments, the wedge 110 is manufactured from steel. In some embodiments, the wedge 110 is manufactured by precision casting. In some embodiments, the wedge 110 is manufactured by lost wax casting.
[0056] In Figure 1, the outer wear component 120 is located primarily inside the bowl 130. As shown in Figure 3, the upper end of the outer wear component 120 extends upward from the adjacent structure of the bowl 130. Figure 3 also shows that the rim 132 of the bowl faces the outer wear component to support the support base of the wedge 110. In some embodiments, the rim 132 has an annular single-wall groove or support ring 312 for supporting the wedge 110. Figure 3 further shows a shim 320 fitted to the bottom of the wedge 110 to increase the height of the outer wear component. Such gradual height additions may be necessary when wear of the outer wear component requires a height that exceeds the height achievable by tightening the wedge 110.
[0057] Let's return to the wedge 110 shown in Figure 2. In some embodiments, the ridge 230 has a front surface 230f and a rear surface 230r on the opposite side. In Figure 3, the rear surface 230r is convex toward the central axis 140, and as a result, the ridge is thinner in the central part (for example, within 5 percent of the longitudinal center of the wedge 110) than at the ends. Advantageously, the convex shape of the rear surface can reduce the weight of the wedge 110. Reducing the weight of the wedge 110 can contribute to reducing the overall mass of the cone crusher. Alternatively, it may make it easier to remove the wedge 110 with a hammer. This is because it reduces the inertial force that diminishes the effect of the hammer impact.
[0058] In Figure 2, the wedge 110 has a rounded edge between the ridge and the shelf. This rounding of the edge reduces stress concentration and simplifies the manufacturing of the wedge 110. Figure 2 also shows other rounded edges provided on the ends of the shelf and other rims, such as between the radial outer surface of the heel and the bottom surface of the ridge, and in some embodiments, all of them. Instead of a rounded shape, one or more edges may be chamfered.
[0059] The shelf section has an open lower end, i.e., a tip. This allows the wedge 110 to slide under the lip. The shelf section also has a closed end at the tail end opposite the tip. This closed end forms a stopper. The stopper has a stopper surface located in the radial plane with respect to the central axis 140. The stopper surface is at an acute angle with respect to the shelf section. The wedge 110 has a rounded edge between the stopper surface and the shelf section.
[0060] In some embodiments, during the operation of the cone crusher, the front surface has a circular shape that is at a constant distance from the central axis 140.
[0061] In Figure 1, the bowl defines a conical receiving space for the outer wear component 120.
[0062] In some embodiments, the front surface of the heel portion 210 is at a certain distance from the central axis 140. Therefore, as shown in Figure 3, for example, the heel portion 210 can be aligned with the edge of the rim 132.
[0063] In some embodiments, the rear surface 210r of the heel portion 210 is at a certain distance from the central axis 140. The rear surface of the heel portion 210 is configured to face the shoulder portion 134 of the bowl. The shoulder portion 134 is at a certain distance from the central axis 140. Preferably, the heel portion 210 is configured to move along the rim 132 when tightened so that it remains aligned with the rim 132.
[0064] The heel portion 210 is formed higher than the shoulder portion 134, thereby allowing the wedge 110 to extend below the shoulder portion 134. In some embodiments, the rear surface 230r of the ridge 230 is located further outward than the shoulder portion 134. That is, the rear surface 230r is further from the central axis 140 than the shoulder portion 134.
[0065] Most or all of the rim of the wedge 110 is preferably rounded in order to reduce stress concentration, and / or to facilitate the installation and removal of the wedge 110, and / or to simplify the manufacture of the wedge 110.
[0066] Preferably, the system includes multiple wedges 110, for example, three or more. Three wedges 110 are advantageous for securely fastening the outer wear component 120 to the bowl 130 while avoiding excessive redundancy. Alternatively, more than three wedges 110 may be used to reduce the force per mounting point of the wedges 110 and increase structural redundancy to reduce the risk of mechanical failure.
[0067] In some embodiments, the system 100 includes an intermediate support member 150. The intermediate support member is detachably attached to the top surface of the bowl, for example, by bolts and nuts, after the wedge 110 has been installed.
[0068] In some embodiments, the intermediate support member 150 includes a first tangential clamping member, such as a bolt 410. The first tangential clamping member is configured to hold the wedge 110 in place. In Figure 4, the intermediate support member further includes a second tangential clamping member, here another bolt 410'. The reference numerals are slightly distinguished for reference. The second tangential clamping member 410' is configured to abut against the radial projection 170 (or lug) of the outer wear part 120. This prevents the outer wear part 120 from rotating when the wedge 110 is pushed into place (i.e., below the lip 122). Advantageously, the second tangential clamping member 410' can prevent or reduce the risk of the outer wear part 120 rotating uncontrollably to an angle that would improperly tighten it below the shelf portion 220 of the wedge 110.
[0069] In some embodiments, the system 100 further comprises one or more wedge shims 320 positioned below the wedge 110 to change the height position of the wedge 110. The shims 320 are bolted to the bottom of the wedge 110.
[0070] In some embodiments, the first tangential clamping member 410 can be fixed at a first height and a second height. In some embodiments, the first tangential clamping member 410 can be fixed at one or more different heights between the first height and the second height. In some embodiments, the first tangential clamping member 410 can be fixed at one or more different heights depending on the height position of the wedge 110. In Figure 4, the height of the first tangential member 410 is adjustable by providing a vertical groove that allows the first tangential member 410 to be positioned appropriately relative to the opposing surface of the wedge 110.
[0071] In some embodiments, the second tangential clamping member 410' can be fixed at a third height and a fourth height. In some embodiments, the second tangential clamping member 410' can be fixed at one or more different heights between the third height and the fourth height. In some embodiments, the second tangential clamping member 410' can be fixed at one or more different heights depending on the height position of the outer wear part 120. In Figure 4, the height of the second tangential member 410' is adjustable by providing a vertical groove that allows the second tangential member 410' to be positioned appropriately with respect to the opposing surface of the lug portion 170 of the outer wear part 120.
[0072] In some embodiments, the intermediate support member 150 includes a base plate 430. In some embodiments, the base plate 430 is curved to fit the outer wear part 120.
[0073] In some embodiments, the intermediate support member 150 further comprises a first upright member 440 attached to one end of the base plate 430. In some embodiments, the first upright member 440 comprises an opening for receiving a first tangential clamping member 410.
[0074] In some embodiments, the intermediate support member 150 further comprises a second upright member 440' attached to the other end of the base plate 430. In some embodiments, the second upright member 440' comprises an opening for receiving a second tangential clamping member 410'.
[0075] In some embodiments, the system 100 comprises a plurality of intermediate support members 150. In some embodiments, the system 100 further comprises one intermediate support member 150 corresponding to each of at least two wedges 110.
[0076] In some embodiments, the system 100 includes an actuator support 500, as shown in Figure 5. The actuator support 500 is configured to prevent uncontrollable rotation of the outer wear part 120. The actuator support 500 is configured to provide a support surface for a hydraulic actuator (not shown) when the wedge 110 is slid out.
[0077] The actuator support portion 500 has a resistance surface configured to face the bowl. This resistance surface is at an angle perpendicular to the force received from the hydraulic actuator when the wedge 110 is removed. Alternatively, the resistance surface is at an angle greater than 90 degrees to the force received from the hydraulic actuator when the wedge 110 is removed. As a result, a radial force component toward the outer wear part 120 is applied to this resistance surface in the actuator support portion 500.
[0078] The actuator support portion 500 is configured to prevent excessive rotation of the outer wear part 120 by a first anti-rotation shape that cooperates with a second anti-rotation shape on the outer surface of the outer wear part 120. The first anti-rotation shape and the second anti-rotation shape complement each other. The first anti-rotation shape is a recess or projection. The second anti-rotation shape is a projection or recess. The projection is a vertical ridge.
[0079] The actuator support section 500 is equipped with a handle 540.
[0080] The actuator support 500 includes a top plate 510. This top plate is shaped to prevent excessive rotation of wear parts. The actuator support 500 includes end plates 520 at both ends. In some embodiments, the end plates 520 are perpendicular to the top plate 510. The actuator support 500 includes side walls 530 configured to extend from the outer edge of one end plate 520 to the outer edge of the other end plate 520.
[0081] In some embodiments, the actuator support portion 500 is configured to provide a mounting support surface, as illustrated in Figure 6. This mounting support surface is configured to face the tail end of the wedge 110 when the wedge 110 is inserted between the bowl and the outer wear component 120. The mounting support surface is configured to support the hydraulic actuator 610 (e.g., a hydraulic ram or hydraulic jack) when the wedge 110 is pressed in.
[0082] The actuator support section 500 is movable in order to remove and attach the wedges 110 one by one.
[0083] Figures 1, 6, and 7 further show the actuator support restraint portion 160. The actuator support restraint portion 160 is integrally formed with the bowl, for example, by forming a recess of an appropriate shape, as shown in these figures. The actuator support restraint portion 160 basically prevents the actuator support from moving outward when the actuator support supports the hydraulic actuator 410. In one embodiment (not shown), the actuator support restraint portion is bolted to the bowl. In one embodiment (not shown), the actuator support restraint portion is welded to the bowl. In one embodiment (for example, Figures 1, 6, and 7), the actuator support restraint portion is configured to lock the actuator support 500.
[0084] In the embodiment illustrated in Figure 7, the actuator support restraint portion 160 is configured to lock the actuator support portion 500 against the force generated when attaching the wedge 110. In some embodiments, the actuator support restraint portion 160 is configured to lock the actuator support portion 500 against the force generated when removing the wedge 110.
[0085] Figure 8 shows a flowchart of wedge mounting according to one embodiment. 810: The lip of the cone crusher's external wear component 120 is supported on the rim of the bowl of the cone crusher by an arc-shaped wedge. 820: The laterally protruding heel portion of the arc-shaped wedge is fitted to the laterally recessed shoulder portion of the ball. 830: An arc-shaped wedge is engaged with the bottom surface of the lip of the outer wear part 120 by a shelf portion that is inclined tangentially.
