Description

Technical Field

[0001] The present disclosure generally relates to wear part removal, for example, to a wear part removal system.

Background Art

[0002] Earthmoving machines such as excavators, wheel loaders, track-type tractors, and loaders generally include implements constructed to excavate, cut, break up, remove, demolish, transport, or otherwise handle materials such as rock, soil, sediment, or waste. The implements often repeatedly wear periodically along their edges as a result of engagement with the materials. To protect the edges, the implements can include one or more replaceable wear parts (also called ground engaging tools (GET)), such as teeth, couplers, adapters, lip shrouds, caps, and / or the like. The one or more replaceable wear parts then withstand most of the wear, impact, or other forces that normally cause wear or damage during use of the implement.

[0003] Over time, due to wear or damage of the replaceable wear parts, the replaceable wear parts may deteriorate, malfunction, or otherwise need to be replaced. To replace the replaceable wear parts, it is necessary to remove the replaceable wear parts from the adapter or mount. However, this is often difficult because dust, dirt, or grime adhering to the replaceable wear parts can cause the replaceable wear parts to adhere (e.g., stick) to the adapter or mount. This requires a large tensile force or other means to remove or loosen the fine powder, dust, or grime that has been impacted to enable removal of the replaceable wear parts.

[0004] For example, an operator can physically loosen and / or remove replaceable wear parts using hand tools (e.g., a sledgehammer can be used to remove a wear part from an adapter). Further, due to high temperatures, low temperatures, rain, snow, sleet, ice, uneven terrain, limited work areas, and / or similar environmental conditions, it can be difficult and / or time-consuming to remove replaceable wear parts.

[0005] U.S. Patent Application Publication No. 2019 / 0360180 (the ’180 publication) discloses a manipulator that can be used to remove and / or attach wear parts of equipment in mining, construction, dredging, and / or other operations. According to the ’180 publication, the manipulator includes a gripper assembly that holds a wear part when the wear part is attached to an earthworking device or when removed from the earthworking device. The manipulator can include a vibrator that, in cooperation with the gripper, can remove a wear part engaged with the ground from the earthworking device. For example, as disclosed in the ’180 publication, the vibrator can vibrate an arm of the gripper that grips the wear part.

[0006] The ’180 publication discloses a manipulator for removing a wear part, but the manipulator only contacts the wear part through a gripper that applies a tensile force to the wear part. As a result, vibrations generated by the vibrator of the manipulator (e.g., vibrating an arm of the gripper that grips the wear part) do not directly act on the wear part. This can affect the ability of the manipulator to remove or loosen fine powder, dust, and dirt that have affected the wear part, and can affect the ability of the manipulator to remove the wear part by applying a pulling force by the gripper.

[0007] Further, in some cases, if the worn part is worn and / or damaged, or if the worn part is wet or covered with ice, etc., the gripper may not be able to maintain a grip on the worn part. Therefore, in this case, the manipulator cannot remove the wear part.

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present disclosure relates to a wear part removal system suitable for any machine that requires removal of wear parts. The term "machine" means any machine that performs operations related to industries such as mining, construction, agriculture, transportation, or other industries. For example, the machine may be, among other examples, an earthmoving machine or a material moving machine such as an excavator, a wheel loader, or a track-type tractor and loader.

[0014] Figures 1A - 1B are diagrams of an exemplary wear part assembly 100. As shown in Figures 1A - 1B, the wear part assembly 100 can include an adapter 102 for a wear part 104 (also referred to as a tip, tooth, or ground engaging tool (GET) for example). The adapter 102 may be configured to attach to and / or cover an edge of an implement 106 (such as a blade, loader bucket, excavator bucket, or any other implement having a ground engaging edge or material engaging edge that is subject to wear during use). The wear part 104 can be configured to attach to the adapter 102 and may be configured to protect the edge of the implement 106 by covering the edge of the implement 106 and engaging with soil or material while the implement 106 is in use. The wear part 104 can include a retaining mechanism (not shown) for securing the wear part 104 to the adapter 102. As shown in Figures 1A - 1B, the retaining mechanism can utilize aspects of the adapter 102 and the wear part 104, such as one or more retaining openings 108 on a side surface of the wear part 104, to secure the wear part 104 to the adapter 102 while the implement 106 is in use. As shown in Figures 1A - 1B, when attached to the adapter 102, the wear part 104 can extend outwardly from the edge of the implement 106 for engaging with the ground or material (not shown).

[0015] Although specific wear part assemblies 100, adapters 102, and wear parts 104 are shown in Figures 1A - 1B, the expected embodiments can include any type of wear part assembly, adapter, wear part, and / or the like related to a machine's implement (such as any coupler, mount, adapter, tooth, tip, lip shroud, cap, or any other GET for example).

[0016] As described above, Figures 1A - 1B are provided as an example. Other examples may differ from the examples described with reference to Figures 1A - 1B.

[0017] Figures 2A - 2D are diagrams of an exemplary wear part removal system 200 described herein. The wear part removal system 200 can be used to remove or facilitate the removal of wear part 104. Figure 2A is a side view of the wear part removal system 200. Figure 2B is a top view of the wear part removal system 200. Figure 2C is an inclined side view of the wear part removal system 200. Figure 2D is a front view of the wear part removal system 200.

[0018] As shown in FIGS. 2A - 2D, the wear part removal system 200 can include a base 202, a handle 204 that can include one or more controls 206, a handle pivot point 208, a clamp system 210 that can include a plurality of clamps 212, a vibration device 214, a contact component 216, a positioning system 218, and / or at least one suspension point 220.

[0019] The base 202 can provide a physical structure that supports the handle 204, the clamp system 210, the vibration device 214, the contact component 216, the positioning system 218, and / or one or more additional components of the wear part removal system 200. For example, the handle 204, the clamp system 210, the vibration device 214, the contact component 216, the positioning system 218, and / or one or more additional components of the wear part removal system 200 can each be attached to the base 202 by one or more fasteners. One or more hydraulic control components 222 can be attached to the base 202 to control (e.g., actuate or stop, pressurize or depressurize, etc.) one or more hydraulic actuators of the wear part removal system 200 (as will be described later with respect to, for example, the clamp system 210, the vibration device 214, and / or the positioning system 218). The one or more hydraulic control components 222 can be connected to a hydraulic pump (not shown) configured to supply pressurized hydraulic fluid to one or more hydraulic actuators via the one or more hydraulic control components 222.

[0020] The handle 204 can be pivotally connected to the base 202 via a handle pivot point 208. The handle pivot point 208 (including, for example, a pivot pin or similar pivot component) can enable relative movement between the handle 204 and the base 202 (and / or other components of the wear part removal system 200). The handle pivot point 208 can fix or "lock" the handle 204 in a specific position relative to the base 202. In this way, the operator of the wear part removal system 200 can interact with the handle 204 via the handle bar 224 of the handle 204 to adjust and fix the handle 204 to a height and / or angle at which the operator can operate one or more controls 206, apply a pressing force to the handle 204 via the handle bar 224 (e.g., clamp the wear part 104 with the clamping system 210 and / or guide the contact component 216 contacting the wear part 104), apply a tensile force to the handle 204 via the handle bar 224 (e.g., when the clamping system 210 clamps the wear part 104, the clamping system 210 applies a tensile force to the wear part 104), and / or the like. In some embodiments, the base 202 and / or the handle 204 can include a damper component (not shown) configured to reduce the amount of vibratory force (e.g., the vibratory force generated by the vibration device 214 as described herein) transmitted to the handle 204 and / or the handle bar 224 or transmitted via the handle bar 224. In this way, the operator of the wear part removal system 200 can freely interact with the handle 204 via the handle bar 224 (e.g., apply a tensile force to the handle 204) to facilitate the removal of the wear part 104 without experiencing potentially uncomfortable vibrations.

[0021] The handle 204 can include or be attached to one or more controls 206 (e.g., on or near the handlebar 224). The one or more controls 206 can include one or more levers, knobs, switches, dials, buttons, and / or the like configured to control one or more components of the wear part removal system 200. For example, the one or more controls 206 can control the tilt angle of the contact component 216 (e.g., enabling the contact component 216 to contact the wear part 104 as described herein), the approach angle of the wear part removal system 200 (e.g., enabling the clamp system 210 to clamp the wear part 104 and / or the contact component 216 to contact the wear part 104 as described herein), the actuation or stopping of the clamp system 210 (e.g., enabling a plurality of clamps 212 to clamp or release the wear part 104), the actuation or stopping of the vibration device 214 (e.g., enabling the vibration device to generate a vibration force or stop generating it as described herein), and / or the like. In some embodiments, an operator of the wear part removal system 200 can interact with the one or more controls 206 to control one or more components of the wear part removal system 200 and facilitate the removal of the wear part 104. As described herein, the one or more controls 206 can send one or more control signals to one or more hydraulic control components 222 to control one or more hydraulic actuators of the wear part removal system 200 (e.g., actuate or stop, pressurize or depressurize, etc.) (e.g., after the operator interacts with the one or more controls 206).

[0022] The clamping system 210 can include a plurality of clamps 212 configured to clamp the worn part 104 (e.g., to facilitate removal of the worn part 104). The plurality of clamps 212 may be configured to clamp the side surface of the worn part 104. In this way, the plurality of clamps 212 can apply a clamping force to the worn part 104 (e.g., facilitate applying a tensile force, a pressing force, and / or a vibration force to the worn part 104 as described herein). For example, the plurality of clamps 212 can apply a clamping force of about 4,000 to 6,000 pounds (lbs) to the worn part 104. One of the plurality of clamps 212 can include an engagement component 226 (e.g., a pin, a rod, or other fastener) that engages the retention opening 108 of the worn part 104 when the clamping system 210 clamps the worn part 104. The engagement component 226 can be inserted into the retention opening 108 and can enable the clamp 212 to clamp the worn part 104 without sliding (or with minimal sliding). In some embodiments, one of the plurality of clamps 212 can include an anti-slip component (not shown), such as a rubber-like friction-inducing material, configured to provide a grip on the worn part 104 when the clamping system 210 is clamped to the worn part 104.

[0023] One of the plurality of clamps 212 can include at least one hydraulic actuator 228, or other components (such as a pneumatic actuator or an electric actuator), configured to operate the clamp 212 (e.g., to clamp the worn part 104). An operator of the worn part removal system 200 can interact with one or more controls 206 to clamp or release the worn part 104 to / from the plurality of clamps 212. For example, one or more controls 206 can transmit one or more control signals to one or more hydraulic control components 222 based on an input by the operator to control each hydraulic actuator 228 of the plurality of clamps 212 (e.g., operate or stop, pressurize or depressurize, etc.).

[0024] The vibration device 214 may be configured to generate a vibration force on the worn part 104 (e.g., by the contact component 216 as described herein). The vibration device 214 may have an impact frequency of about 2000 - 2500 beats per minute and can generate a vibration force of 3500 - 9000 pounds. The weight of the vibration device 214 may be about 450 - 900 pounds, and the vibration device 214 may be configured to apply a part of its weight to the worn part 104 (e.g., via the contact component 216 as described herein) (e.g., as a pressing force). In some embodiments, an operator of the worn part removal system 200 can interact with one or more controls 206 to operate or stop the vibration device 214 (e.g., generate or stop generating the vibration force). For example, one or more controls 206 can transmit one or more control signals to the vibration device 214 to control its operation (e.g., operate or stop) based on an input by the operator.

[0025] The contact component 216 may be configured to contact a part of the worn component 104. For example, the contact component 216 may be configured to contact the upper surface of the worn component 104 (e.g., before or after the clamping system 210 clamps the worn component 104). The contact component 216 may be configured to transmit the vibration force generated by the vibration device 214 to a part of the worn component 104 and / or to apply a part of the weight of the vibration device 214 to a part of the worn component 104 (e.g., as a force to push down the worn component 104). For example, the contact component 216 may be attached to the bottom surface of the vibration device 214 (e.g., by one or more fasteners), thereby enabling the vibration force generated by the vibration device 214 to be transmitted from the vibration device 214 to a part of the worn component 104 via the contact component 216. This also makes it possible to apply a part or all of the weight of the vibration device 214 to the contact component 216, and thus the weight applied to the contact component 216 is applied to a part of the worn component 104.

[0026] The contact component 216 may be configured to maintain contact with a part of the wear part 104 (for example, when the vibration force is transmitted from the vibration device 214 to a part of the wear part 104). For example, the contact component 216 may be configured with at least one hydraulic actuator 230 configured to fix the contact component 216 to a part of the wear part 104, or (for example, when the contact component 216 transmits the vibration force from the vibration device 214 to a part of the wear part 104) may be associated with other components (for example, a pneumatic actuator or an electric actuator) configured to prevent the contact component 216 from lifting off a part of the wear part 104. Alternatively, the contact component 216 may be configured to float (for example, bounce) on a part of the wear part 104 (for example, when the vibration force is transmitted from the vibration device 214 to a part of the wear part 104). For example, at least one hydraulic actuator 230 may be configured to allow the contact component 216 to move on a part of the wear part 104 (for example, when the contact component 216 transmits the vibration force from the vibration device 214 to a part of the wear part 104, may be configured to allow the contact component 216 to repeatedly leave and lift off a part of the wear part 104).

[0027] The operator of the wear part removal system 200 can interact with one or more controls 206 to control the tilt angle of the contact component 216 (for example, with respect to the wear part 104, with respect to the ground level, etc.) so that the contact component 216 can be placed on a part of the wear part 104 (for example, before the vibration device 214 starts generating the vibration force). For example, one or more controls 206 can transmit one or more control signals to one or more hydraulic control components 222 based on the operator's input to control at least one hydraulic actuator 230 so that a preferred tilt angle of the contact component 216 is obtained (for example, activate or stop, pressurize or depressurize, and / or the like).

[0028] The positioning system 218 may be configured to control the approach angle of the wear part removal system 200 to the wear part 104 (e.g., with respect to the wear part 104, with respect to the ground level and / or the like). For example, the clamping system 210 clamps the wear part 104 and / or the contact component 216 enables contact with the wear part 104. In some embodiments, the positioning system 218 can include at least one suspension point 220 configured to be attached to a lifting device (e.g., a crane boom) via a rigging or other support material. Accordingly, the wear part removal system 200 may be suspended above or near the wear part 104 by a lifting device via at least one suspension point 220.

[0029] The positioning system 218 can include one or more other components (e.g., structural components) attached to the base 202 or other components of the wear part removal system 200. In some embodiments, the positioning system 218 may be pivotally connected to the base 202 via one or more positioning pivot points 232. The positioning pivot points 232 (including, for example, pivot pins or similar pivot components) can enable relative movement between the positioning system 218 and the base 202 (and / or other components of the wear part removal system 200).

[0030] The positioning system 218 may be associated with at least one hydraulic actuator 234 or other component (e.g., a pneumatic actuator or an electric actuator) configured to control the pivotal rotation of the positioning system 218 via one or more positioning pivot points 232. For example, the at least one hydraulic actuator 234 may operate to pivot the positioning system 218 about one or more positioning pivot points 232 until a preferred approach angle of the wear part removal system 200 is obtained. An operator of the wear part removal system 200 may interact with one or more controls 206 to cause the at least one hydraulic actuator 234 to pivot the positioning system 218 via one or more positioning pivot points 232 to obtain a preferred approach angle of the wear part removal system 200. For example, the one or more controls 206 may transmit one or more control signals to one or more hydraulic control components 222 based on an input by the operator to control the at least one hydraulic actuator 234 (e.g., activate or deactivate, pressurize or depressurize, etc.).

[0031] Additionally or alternatively, the positioning system 218 may be associated with at least one accelerometer device (not shown) configured to maintain the approach angle of the wear part removal system 200 in relation to at least one hydraulic actuator 234 (e.g., when the vibration device 214 is generating a vibration force, when the contact component 216 is floating on the wear part 104, when the wear part 104 is removed from the clamping system 210, or when it is displaced relative to the clamping system 210, and / or similar cases). For example, if at least one accelerometer device senses a change in acceleration (e.g., due to a shift in the position of the positioning system 218 relative to the base 202 and / or other components of the wear part removal system 200), the at least one accelerometer device transmits a control signal to at least one hydraulic actuator 234 and actuates the at least one hydraulic actuator 234 to pivot the positioning system 218 on one or more positioning pivot points 232 until the preferred approach angle of the wear part removal system 200 is regained.

[0032] The wear part removal system 200 can include one or more additional components. For example, the wear part removal system 200 can include a catch component (e.g., the catch component 502 shown in FIG. 5) configured to catch the wear part 104 after the wear part 104 has been removed by the wear part removal system 200 (e.g., after a tensile force, a pressing force, and / or a vibration force has been applied to the wear part 104 by the wear part removal system 200 as described herein). The catch component may be configured to hold the wear part 104 (e.g., when the wear part removal system 200 moves to another position). The catch component can include a mechanism or may be configured such that an operator of the wear part removal system 200 interacts with the mechanism to release (e.g., drop or place) the catch component with the wear part 104 (e.g., in a waste container). In this way, the wear part removal system 200 can facilitate both the removal and disposal of the wear part 104.

[0033] As described above, FIGS. 2A-2D are provided as an example. Other examples may be different from the examples described with reference to FIGS. 2A-2D.

[0034] FIG. 3 is a top view of an exemplary clamp system 300 (e.g., corresponding to the clamp system 210). As shown in FIG. 3, the clamp system 300 can include a plurality of clamps 212, the clamps 212 can include engagement components 226, and can be associated with at least one hydraulic actuator 228 (e.g., as described herein with reference to FIGS. 2A-2D). As further shown in FIG. 3, the clamp system 300 can include a clamp base 302 and one or more clamp pivot points 304. The clamp base 302 can provide a physical structure that supports the plurality of clamps 212 and the hydraulic actuators 228 respectively associated with the plurality of clamps 212.

[0035] One of the plurality of clamps 212 may be pivotally connected to the clamp base 302 via at least one of the one or more clamp pivot points 304. At least one clamp pivot point 304 (including, for example, a pivot pin or a similar pivot component) can enable relative movement between the clamp 212 and the clamp base 302. For example, the hydraulic actuator 228 associated with the clamp 212 may be actuated so that the clamp 212 pivots about at least one clamp pivot point 304 and the clamp 212 clamps the wear part 104 (e.g., as described herein).

[0036] As described above, FIG. 3 is provided as an example. Other examples may be different from the examples described with reference to FIG. 3.

[0037] Figures 4A - 4B are diagrams 400 of exemplary handle positions and approach angles of the wear part removal system 200 described herein. As shown in FIG. 4A, the wear part removal system 200 can have an approach angle 402 and a handle position angle 404 to the wear part 104. For example, an operator of the wear part removal system 200 can interact with one or more controls 206 such that at least one hydraulic actuator 234 pivots the positioning system 218 via one or more positioning pivot points 232 to adjust the wear part removal system 200 to the approach angle 402. Additionally or alternatively, the operator can interact (e.g., “unlock”) with the handle pivot point 208 to pivot the handle 204 to the handle position angle 404. As shown in FIG. 4B, the wear part removal system 200 can have an approach angle 406 and a handle position angle 408 to the wear part 104. For example, an operator of the wear part removal system 200 can interact with one or more controls 206 such that at least one hydraulic actuator 234 pivots the positioning system 218 via one or more positioning pivot points 232 to adjust it to match the approach angle 406 (e.g., approach angle 402). Additionally or alternatively, the operator can interact with the handle pivot point 208 to pivot the handle 204 to the handle position angle 408 (e.g., handle position angle 404).

[0038] As described above, FIGS. 4A - 4B are provided as an example. Other examples may differ from the examples described with reference to FIGS. 4A - 4B.

[0039] Figures 5A-5B are diagram 500 of exemplary tilt angles of contact component 216. As shown in FIGS. 5A-5B, wear part removal system 200 may include a catch component 502 (corresponding to the catch component described herein with reference to FIGS. 2A-2D, for example) that catches wear part 104 when wear part 104 is removed by wear part removal system 200. As further shown in FIG. 5A, a plurality of clamps 212 of wear part removal system 200 can clamp wear part 104, and contact component 216 can have a tilt angle 504. For example, an operator of wear part removal system 200 may interact with one or more controls 206 to cause at least one hydraulic actuator 230 to tilt contact component 216 to tilt angle 504 (for example, before contact component 216 descends to contact the upper surface of wear part 104, a plurality of clamps 212 may clamp wear part 104 unrestrictedly). As further shown in FIG. 5B, contact component 216 may have a tilt angle 506 that is less than tilt angle 504 so that contact component 216 can contact the upper portion of wear part 104. For example, an operator of wear part removal system 200 may interact with one or more controls 206 to cause at least one hydraulic actuator 230 to tilt contact component 216 to tilt angle 506 (for example, to enable contact component 216 to contact the upper surface of wear part 104 and apply a portion of the weight of vibration device 214 and / or the vibration force generated by vibration device 214 to the upper surface of wear part 104).

[0040] As described above, FIGS. 5A-5B are provided as examples. Other examples may be different from the examples described with reference to FIGS. 5A-5B.

Industrial Applicability

[0041] Some embodiments described herein provide a wear part removal system that can remove a wear part (e.g., from an adapter). The wear part removal system includes a handle and one or more controls configured such that an operator of the wear part removal system can control how the wear part removal system approaches, aligns with, attaches to, and / or applies one or more forces (e.g., a tensile force, a pressing force, and / or a vibrational force) to the wear part to facilitate removal of the wear part. For example, the operator can interact with the handle and the one or more controls to control a positioning system of the wear part removal system to control an approach angle of the wear part removal system to the wear part, control a clamping system of the wear part removal system such that the clamping system clamps the wear part, and / or control an inclination angle of a contact component of the wear part removal system such that the contact component contacts a portion of the wear part and can apply a pressing force to the wear part (e.g., associated with a portion of the weight of a vibration device of the wear part removal system). Further, the operator can pull the handle to apply a tensile force to the wear part (e.g., via the clamping system) and / or interact with the one or more controls to activate a vibration device to apply a vibrational force to the wear part (e.g., via the contact component). Accordingly, the wear part removal system can remove the wear part.

[0042] In this way, the worn part removal system enables the removal of worn parts regardless of whether the worn parts are fixed to the adapter or mount (e.g., due to impacted fine powder, dust, or dirt). Further, since the worn part removal system utilizes a plurality of components to contact and / or grip the worn parts and is configured to apply multiple types of forces to the worn parts, it can quickly and efficiently remove worn parts that are difficult and / or time-consuming to remove with conventional removal techniques. For example, if the clamp of the clamping system includes an engaging component that engages with the holding opening of the worn part, the clamping system can securely grip and hold the worn part even if the worn part has become smooth due to wear or other damage. As another example, the worn part removal system can contact the worn part (e.g., via a contact component) and apply a pressing force and / or a vibration force to the worn part to remove the worn part without gripping it. This is beneficial when the clamping of the worn part by the clamping system is hindered by environmental conditions (e.g., when the worn part is wet or covered with ice).
