Abstract
Description
Technical Field
[0001] This disclosure generally relates to a machine having a movable operator station, and more specifically to a machine having a system that selectively restricts the movement of the operator station under certain conditions. Background Technology
[0002] For example, various types of machines used in the construction industry include operator stations. Operator stations contain various systems and controls that allow operators to control the machine to perform operations (e.g., paving, milling, etc.). These operator stations are generally located at the rear of the machine frame, which can obstruct operator visibility and / or interfere with the operator's ability to supervise various aspects of the operation.
[0003] Some machines may include a movable operator station to improve operator visibility when operating the machine under certain conditions. For example, U.S. Patent 10,100,471 to Berning et al. discloses an automobile manufacturing machine with an operator platform that can be moved laterally on the machine frame in the direction of travel and outward beyond the lateral outer wall of the machine frame. When extended laterally outward, the machine operator on the operator platform can observe the lateral outer wall and the area adjacent to it.
[0004] However, on some machines, a mobile operator station may interfere with one or more other components of the machine, potentially causing damage to the components, the operator station, and / or the system used to move the operator station. Summary of the Invention
[0005] According to some embodiments, this disclosure relates to a mobile machine having: a machine frame with a transverse outer wall; an operator station having an outer edge; an actuation system configured to move the operator station between a retracted position and a fully extended position laterally outward from the retracted position, wherein in the fully extended position, the outer edge is a first distance outward from the transverse outer wall; a movable member movable between a first position and a second position; a sensor configured to transmit a signal indicating that the movable member is in the first position; and a controller configured to limit the distance that the operator station can move laterally outward from the retracted position to a second distance in response to receiving a signal from the sensor, wherein the second distance is less than the first distance.
[0006] According to some embodiments, this disclosure relates to a method for preventing interference between a movable operator station of a mobile machine and a movable component of the mobile machine, wherein the operator station is movable between a retracted position and a fully extended position of a first laterally outward distance from the retracted position. The method includes sending a signal indicating that the movable component is in the first position, and limiting the laterally outward movement of the operator station from the retracted position to a second distance less than the first distance.

[0024] Figure 1 and Figure 2 This is a diagram of an exemplary machine 100 including a mobile operator station 102 and a work implement 104 (i.e., schematically shown in dashed lines because the work implement may not be visible from the outside of the machine). In some embodiments, machine 100 may be a mobile machine, such as construction equipment in the construction industry for performing construction tasks via work implement 104. As examples, machine 100 may include a cold planer (i.e., a milling machine), a rotary mixer, an asphalt paver, etc. Exemplary work implement 104 may include a cutting drum or crusher, a rotor chamber, a crusher bar, a mixing chamber, a hopper, a conveyor, a leveling component, etc. Figure 1 and 2 As shown, operator station 102 can be movable relative to machine 100 and / or work equipment 104, allowing the operator to be located outside the machine frame (e.g., the machine body). In this way, the operator's visibility of the tasks performed by machine 100 and / or work equipment 104 can be improved.
[0025] refer to Figure 2In some embodiments, operator station 102 may be linearly movable relative to machine 100 and / or work fixture 104. For example, operator station 102 may be linearly translated relative to machine 100 and / or work fixture 104 to position operator station 102 outside the machine frame. In this way, machine 100 can prevent the operator (not shown) positioned in operator station 102 from obstructing the view of the operator. In some embodiments, operator station 102 may be moved a distance X such that the operator positioned in operator station 102 can be positioned outside machine 100 (e.g., via sliding, translation, rotation, etc.) to improve visibility. In some embodiments, during linear movement of operator station 102 relative to machine 100 and / or work fixture 104, the operator positioned in operator station 102 may remain in a forward-facing position.
[0026] In some embodiments, operator station 102 may move a distance X to the outside of machine 100. As examples, distance X may include at least about 25 mm, at least about 50 mm, at least about 100 mm, at least about 200 mm, at least about 215 mm, at least about 300 mm, etc. In some embodiments, distance X may be less than about 25 mm and / or greater than about 300 mm.
[0027] Figure 1 and 2 Provided as an example. Other instances are possible and can be combined. Figure 1 and Figure 2 The examples described are different. In other words, machine 100, components included in machine 100, and / or the arrangement of these components are provided for illustrative purposes only.

For clarity, Figure 3 and Figure 4 The middle part can be omitted. Figure 1 and 2 Some of the components shown and described in connection with this.
[0029] refer to Figure 3 and Figure 4In some embodiments, operator station 102 may include a first end 106, a second end 108 opposite to the first end 106, and a platform 110 extending between the first end 106 and the second end 108. In some embodiments, platform 110 may be disposed in or arranged in a plane P (e.g., schematically shown by dashed lines), and may be translated linearly in and / or along plane P relative to a machine (e.g., see machine 100). Figure 1 and 2 The operator station 102 is moved. In some embodiments, the platform 110 may include a first surface 112 (e.g., an upper surface) and a second surface 114 (e.g., a lower surface) opposite the first surface 112. The platform may be supported on or above the first surface 112 of the platform 110 during operation of the machine including the operator station 102. One or more handrails 116 may be provided to improve operator stability when the operator is sitting or standing on and / or above the platform 110.
[0030] In some embodiments, the operator seat 118 may be positioned near the first end 106 of the operator station 102. Furthermore, in some embodiments, the operator can operate and / or control various aspects of the machine via one or more controls located in the operator console area 120 of the operator station 102. Such controls can be used to control work implements (e.g., work implement 104, etc.). Figure 1 (e.g., speed, direction, etc.) Actuating work tools, controlling machines, actuating machines, etc. Such controls may also be used to move operator station 102 relative to the machine and / or relative to components included in the machine and / or components associated with the machine.
[0031] refer to Figure 4 In some embodiments, operator station 102 may include actuation system 122. Actuation system 122 may be configured to move operator station 102 relative to the machine and / or other components included in and / or associated with the machine (e.g., machine frame, work tools, etc.). In some embodiments, actuation system 122 may be configured to move operator station 102 on or above a portion of the machine via a four-bar linkage or system configured to maintain the operator in operator station 102 in a forward-facing position during movement of operator station 102. In some embodiments, actuation system 122 may be located or positioned near a first end 106 of operator station 102. In some embodiments, portions of actuation system 122 may be attached to operator station 102, and other portions of actuation system 122 may be attached to the machine frame (e.g., see machine frame 154). Figure 7 This facilitates movement between operator station 102 and machine frame.
[0032] In some embodiments, the actuation system 122 may include at least a first link member 124, a second link member 126, and an actuation member (e.g., see 142). Figure 5 The corresponding first link member 124 and second link member 126 can be attached to the second surface 114 of the platform 110, and can be actuated by an actuating member (e.g., see actuating member 142). Figure 5 Actuation. In some embodiments, the first link member 124 may include a first proximal end (e.g., see first proximal end 128, Figure 5 The first distal end 130 and the second link member 126 may include a second proximal end (e.g., see second proximal end 132). Figure 5 ) and a second remote 134. Actuation system 122 can be configured to actuate by causing one or more pins attached to the machine frame as described herein (e.g., see pin 136, Figure 5 The corresponding first distal ends 130 and second distal ends 134 of the corresponding first link members 124 and the corresponding link members 126 above, below and / or around the platform 110 are pivoted or rotated synchronously to move the platform 110.
[0033] Turn now Figure 5 and Figure 6 It shows that it can be included in Figure 1 and Figure 2 A plan view of an exemplary operator station 102 in the machine. Figure 5 An exemplary bottom plan view of operator station 102 is shown, including a view along the second surface 114. Figure 6 An exemplary top plan view of operator station 102 is shown, including a view along the first surface 112. For clarity, Figure 5 and Figure 6 The middle part can be omitted. Figure 1-4 Some of the components shown and described in connection with this.
[0034] like Figure 5 As shown, platform 110 may include a first end 138 and a second end 140 opposite to the first end 138. In some embodiments, an actuation system 122 including a first link member 124, a second link member 126, and / or an actuation member 142 may be attached to and / or disposed near the first end 138 of platform 110. A recess 144 may be disposed near the second end 140 of platform 110. In some embodiments, recess 144 may be configured to receive a support member (e.g., see support member 160). Figure 7 The support member can be located on the platform 110 in a plane (e.g., plane P). Figure 3The second end 140 of the platform 110 is supported during movement within and / or along a plane. In some embodiments, the platform 110 may be configured to move in one or more linear directions LD by pivoting the first link member 124 and the second link member 126 relative to one or more corresponding pins 136 in the same pivoting direction PD. In some embodiments, the first link member 124 and the second link member 126, or portions thereof, may remain substantially parallel during pivoting about the pin 136 to allow the platform 110 to translate linearly in or along a plane. In this way, the platform 110 and / or its components and / or components attached to the platform may continuously face the same direction during movement of the platform 110 in and / or along a plane.
[0035] In some embodiments, the actuating member 142 may be attached to a portion of the first linkage member 124. The actuating member 142 may be configured to be coupled to a rod of the first linkage member 124 by linear extension or retraction (e.g., see 145). Figure 7 This causes the first link member 124 to pivot about the corresponding pin 136. The first link member 124 can then cause the second link member 126 to pivot about the corresponding pin 136. In some embodiments, the actuating member 142 may include a linear actuator or linear actuating member, such as a hydraulic cylinder. In some embodiments, the actuating member 142 may include a piston 146 for driving the rod (e.g., schematically shown in dashed lines because the piston may not be visible from the outside of the actuating member 142), and a sensor device 148 (e.g., also schematically shown in dashed lines because the sensor device may not be visible from the outside of the actuating member 142), which may be attached to the piston 146 and / or otherwise disposed near the piston. In some embodiments, the sensor device 148 may be configured to detect the amount of extension or retraction of the piston 146 and / or the rod attached thereto, causing the platform 110 to move a distance (e.g., distance X). Figure 2 The position of the platform 110 can be controlled based on the extension or retraction of the piston 146. In this way, the spatial position of the platform 110 can be determined and / or controlled based on the extension and / or retraction of the piston 146.
[0036] Turn now Figure 6 In some embodiments, operator station 102 may be located on one or more linkage members (e.g., see 124 and 126). Figure 5 During the pivoting of the machine (e.g., see 100, Figure 1 and Figure 2The operator station 102 can rotate inside and / or outside the machine to which it is attached, and the one or more linkage members can collectively form a four-bar linkage system or device. In some embodiments, the operator station 102 and / or its components (e.g., platform 110, operator seat 118, etc.) can be positioned along the facing direction FD and can be held in the facing direction FD during pivoting of one or more linkage members. In this way, the operator can position and / or maintain a desired position (e.g., forward-facing position, etc.) during movement of the operator station 102. In some embodiments, the facing direction FD can correspond to the direction of travel of the machine to which the operator station 102 is attached.
[0037] refer to Figure 6 In some embodiments, the first control device 150 may be located in the operator console area 120 of the operator station 102. As an example, the first control device 150 may include a lever-type control device communicatively coupled to one or more machine systems (e.g., drive systems, tooling systems, etc.) to control various aspects of the machine (e.g., machine speed, machine direction of travel, tasks performed by the machine, etc.). In some embodiments, the second control device 152 may be located in the operator console area 120 of the operator station 102. As an example, the second control device 152 may include a button control device communicatively coupled to the actuation member 142. In this way, the button control device can be used to actuate, drive, indicate, and / or otherwise control the actuation member 142 for moving the operator station 102 relative to the machine inside or outside via an intuitive, operator-friendly control.
[0038] Figure 3-6 Provided as an example. Other instances are possible and can be combined. Figure 3-6 The examples described are different. In other words, operator station 102 is provided for illustrative purposes only, and the arrangement of components and / or parts included in operator station 102 is shown.
[0039] Turn now Figure 7 It shows the connection with the included Figure 1 and Figure 2 A diagram of an exemplary operator station 102 in a machine, associated with an exemplary actuation system 122. For clarity, Figure 7 The middle part can be omitted. Figure 1-6 Some of the components shown and described in connection with this.
[0040] refer to Figure 7 The actuation system 122 may include a first linkage member 124, a second linkage member 126, and an actuation member 142. In some embodiments, the actuation system 122 may be attached to an operator station (e.g., see operator station 102). Figure 3-6The operator station is located on or around the machine frame 154. In this manner, the operator station can move relative to the machine frame 154 and / or the machine formed or connected to the machine frame 154. In some embodiments, one or more mounting members 156 (e.g., mounting plates, brackets, housings, etc.) can be used to attach the pin 136 to the machine frame 154. In this manner, the pin 136 can serve as or act as a pivot axis, about which the first link member 124 and the second link member 126 in the actuation system 122 can pivot when actuated by the actuating member 142. For example, a first distal end 130 of the first link member 124 can be disposed on, above, and / or around the corresponding pin 136 for sliding, rotating, and / or otherwise pivoting about the first pivot axis A1 formed by the corresponding pin 136 in a first direction Di. Similarly, the second distal end 134 of the second link member 126 may be disposed on, above, and / or around the corresponding pin 136 for sliding, rotating, or otherwise pivoting about the second pivot axis A2 formed by the corresponding pin 136 in the first direction Di. In some embodiments, the corresponding first pivot axis A1 and second pivot axis A2 may be substantially orthogonal to the components included in the operator station (e.g., see 102). Figure 3-6 The platform in ) (for example, see 110, Figure 3-6 The plane (for example, see plane P,) Figure 3 In some embodiments, the platform and machine frame 154 may be arranged in and / or along a parallel plane, such that the platform can be moved above the machine frame 154 by the actuation system 122.
[0041] In some embodiments, the actuating member 142 or a portion thereof (e.g., its rod 145) may extend or retract based on a hydraulic amount supplied to the actuating member 142. The force or movement associated with the extension or retraction of the actuating member 142 may be imparted to the first link member 124 to cause movement (e.g., pivoting, etc.) in a first direction Di, and to cause movement of the second link member 126 in the first direction Di. In some embodiments, a platform attached to the actuation system 122 (e.g., see 110, Figure 3-6 It can move in a linear direction during pivoting of the first link member 124 and the second link member 126 in the first direction Di.
[0042] In some implementations, the actuation system 122 may be connected to an operator station (e.g., see 102, Figure 3-6The platform is used to move the platform relative to the machine frame 154. For example, one or more connecting members 158 may be used to connect portions of the actuation system 122 to the platform of the operator station. In some embodiments, the first proximal end 128 of the first linkage member 124 may include one or more connecting members 158 that extend between the first linkage member 124 and the platform and / or connect the first linkage member and the platform. Similarly, the second proximal end 132 of the second linkage member 126 may include one or more connecting members 158 connecting the second linkage member 126 to the platform. Exemplary connecting members 158 include, but are not limited to, pins, rods, bars, clamps, bolts, threaded connectors (e.g., screws), etc. In some embodiments, the platform may pivot in a linear direction (e.g., see LD) during pivoting of the first connecting member 124 and the second connecting member 126 in a first direction Di. Figure 6 The platform can be moved such that it remains in the facing direction (e.g., see FD) during pivoting of the first connecting member 124 and the second connecting member 126 in the first direction Di. Figure 6 )superior.
[0043] Still referencing Figure 7 In some embodiments, a support member 160 may be provided on or above the machine frame 154 to support the operator station 102 as it moves relative to the machine frame 154. In some embodiments, the support member 160 may engage a recess in the operator station (e.g., see 144). Figure 5 This is to improve the weight distribution and / or balance of the operator station as it moves relative to the machine frame 154. As an example, the support member 160 may comprise a material with low resistance to movement and / or be at least partially formed of such a material, such as plastic, polymer, and / or metal.
[0044] Figure 7 Provided as an example. Other instances are possible and can be combined. Figure 7 The described examples differ. In other words, the actuation system 122 is provided for illustrative purposes only, and is shown as an arrangement of components and / or parts included in the actuation system 122.
[0045] Figure 8 Is and can be included in Figure 1 and Figure 2 A diagram of an exemplary support system 170 associated with an exemplary operator station 102 in a machine. For clarity, Figure 8 The middle part can be omitted. Figure 1-7 Some of the components shown and described in connection with this.
[0046] refer to Figure 8In some embodiments, the support system 170 may include a groove 144 and a support member 160. In some embodiments, the groove 144 may be provided on, above, and / or within a portion of the platform 110. As an example, the groove 144 may be machined into the platform 110. As another example, the groove 144 may be formed in an attachment member attached to the platform 110 by welding, bolting, or the like. In some embodiments, the support member 160 may be provided in a machine frame (e.g., machine frame 154) facing the platform 110. Figure 7 On or above. As an example, support member 160 may include a support pad that is attached to the machine frame by welding, threaded connection, bolting, etc.
[0047] In some embodiments, the support member 160 may be rigidly attached to the machine frame and move within a recess 144 as the platform 110 moves relative to the machine frame (e.g., by sliding, etc.). In some embodiments, the recess 144 may be configured to engage and / or retain the support member 160, such that the support member 160 may improve the weight distribution of the operator station and / or guide the movement of the operator station relative to the machine frame.
[0048] As mentioned above, Figure 8 Provided as an example. Other instances are possible and can be combined. Figure 8 The examples described are different. In other words, the support system 170 is provided for illustrative purposes only, and the arrangement of components and / or parts included in the support system 170 is shown.
[0049] Figure 9 An exemplary embodiment of a machine 180 including a movable operator station (e.g., operator station 102) is shown. For clarity, Figure 9 The middle part can be omitted. Figure 1-8 Some of the components shown and described are associated with this. Machine 180 can be any machine with a mobile operator station, such as a mobile machine used in the construction industry to perform construction tasks. For example, machine 180 can be a cold planer (i.e., a milling machine), a rotary mixer, an asphalt paver, etc.
[0050] exist Figure 9 In an exemplary embodiment, machine 180 is shown as a cold planer. A “cold planer” can be defined as any machine used to break down and remove a hardened layer of material from an existing road surface. Machine 180 may include a plurality of ground engagement units 182 for advancing machine 180 along a road surface 184. The ground engagement units 182 of machine 180 are connected to the frame 186 of machine 180 via outriggers 188 (e.g., hydraulic outriggers). Although the ground engagement units 182 of machine 180 are shown to include tracks, ground engagement units 182 may alternatively include a set of wheels.
[0051] Frame 186 supports operator station 102 and includes a vertically arranged right-side transverse outer wall 187. The machine also includes a controller 190. One or more control devices 150, 152 can communicate wirelessly or wiredly with controller 190 to provide commands to controller 190. Controller 190 can send control signals based on commands to one or more actuators (not shown) of one or more of ground engagement units 182 and outriggers 188. In the case of electrically activated actuators, the control signals can act directly on the respective actuators. In the case of hydraulically activated actuators, the control signals can act on valves, which in turn control the flow of pressurized fluid to the actuators. Controller 190 can be a separate control unit or part of a central control unit operable to control additional functions of machine 180.
[0052] The frame 186 may also support a power source such as an engine 192. The engine 192 may supply power to the ground engagement unit 182 to propel the machine 180 across the road surface 184. In one embodiment, this is achieved by driving a hydraulic pump (not shown) with the output of the engine 192, which in turn supplies high-pressure hydraulic fluid to a separate electric motor (not shown) associated with the ground engagement unit 182.
[0053] Machine 180 may also include a milling system 194 supported by a frame 186. The milling system 194 may also receive power from an engine 192. The milling system 194 facilitates milling of the road surface 184. The milling system 194 includes a milling drum 196 and a plurality of cutting tools 198 arranged circumferentially around the milling drum 196. The cutting plane of machine 180 is tangent to the bottom of the milling system 194 and parallel to the direction of travel of machine 180. The milling drum 196 of the milling system 194 rotates when it receives power from the engine 192, and thus allows the plurality of cutting tools 198 to repeatedly contact the road surface 184 to remove a layer of material from the road surface 184. When constructed as hydraulic outriggers, the outriggers 188 can function as elongated telescopic actuators configured to raise and lower the milling system 194 relative to the ground engagement unit 182 to control the cutting depth of the milling system 194.
[0054] A conveyor system 200 is mounted on machine 180 to collect materials, such as excavated asphalt produced during the milling of road surface 184 by milling system 194. The conveyor system 200 also transports the collected material to a discharge location, such as a transport vehicle (not shown). Specifically, the conveyor system 200 may include a lower conveyor belt 202 and an upper conveyor belt 204 located adjacent to the lower conveyor belt 202. The lower conveyor belt 202 collects and transports the material to the upper conveyor belt 204, which in turn transports the material to the discharge location. In various embodiments, the upper conveyor belt 204 may be movable relative to the lower conveyor belt 202 in a vertical and / or horizontal direction to adjust the conveyor system 200 relative to the discharge location.
[0055] refer to Figure 10-11 Operator station 102 can be as described above. Figure 1-8 As described above. In some embodiments, as described above, operator station 102 and / or one or more of its components (e.g., operator seat 118) may be positioned along the facing direction FD and remain in the facing direction FD during movement of operator station 102 in the first linear direction LD1 and / or the second linear direction LD2. In this way, the operator can have improved visibility of the cutting operation being performed by machine 180.
[0056] In some embodiments, one or more of the outriggers 188 and the associated ground engagement unit 182 may be movable to provide additional stability to the machine 180 during the cutting process and / or modify the cutting width associated with the machine 180. Figure 10-11 In the illustrated embodiment, the right rear outrigger 188 of machine 180 is movable. In other embodiments, one or more hydraulic outriggers, in addition to or supplementing the right rear outrigger 188, may be movable.
[0057] The right rear outrigger 188 includes a radially extending arm 206 having a distal end 208 configured to be received in a support bracket 210 and mounted to move (e.g., rotate, swing, etc.) about axis A relative to the support bracket in a rotational direction SD. The right rear outrigger 188 may be in a first position (e.g., Figure 12-13 The inner position shown) and the second position (e.g.) Figure 11 and Figure 14-15 Move between the outer positions shown in the diagram.
[0058] Arm 206 includes a pair of vertically aligned first locking pin holes 212 and a pair of vertically aligned second locking pin holes (not shown). Support bracket 210 includes a pair of vertically aligned third locking pin holes 214 associated with a first position of the right rear outrigger 188, and a pair of vertically aligned fourth locking pin holes 216 associated with a second position of the right rear outrigger 188. Figure 11 In the middle, a pair of fourth locking pin holes 216 are vertically aligned with the second locking pin hole (not shown), the second locking pin hole being in Figure 11 The arm covers the middle section. A pair of second locking pin holes (not shown) are substantially similar to the first locking pin holes 212, but are arranged adjacent to the side of the arm 206 opposite to the first locking pin holes 212. However, in other embodiments, the number of first locking pin holes 212, the number of second locking pin holes, the number of third locking pin holes 214, and the number of fourth locking pin holes 216 may each be more or less than two.
[0059] The locking pin 218 is configured to be received in a locking pin hole. Specifically, when the right rear support leg 188 is in the first position, a pair of first locking pin holes 212 are vertically aligned with a pair of third locking pin holes 214, and the locking pin 218 can be received through the aligned first locking pin holes 212 and third locking pin holes 214 to lock the right rear support leg 188 in the first position. Similarly, when the right rear support leg 188 is in the second position, a pair of second locking pin holes (not shown) are vertically aligned with a pair of fourth locking pin holes 216, and the locking pin 218 can be received through the aligned second locking pin holes and fourth locking pin holes to lock the right rear support leg 188 in the second position.
[0060] Machine 180 may include one or more sensors configured to send signals indicating the position of the right rear outrigger 188. The one or more sensors may be configured in various ways, including the number of sensors, the type of sensors, the position and orientation of the sensors, and what the sensors are detecting. In the illustrated embodiment, a first proximity sensor 220 is mounted on the arm 206 of the right rear outrigger 188, near the position where the locking pin 218 will be when installed through a first locking pin hole 212 in the arm 206. The first proximity sensor 220 is configured to sense whether the locking pin 218 is received through the first locking pin hole 212 and send a signal indicating whether the locking pin 218 is so received to controller 190. In an exemplary embodiment, a second proximity sensor (not shown) is mounted on the arm 206 of the right rear outrigger 188, near the position where the locking pin 218 will be when installed through a second locking pin hole (not shown) in the arm 206. The second proximity sensor (not shown) is configured to sense whether the locking pin 218 is received through the second locking pin hole (not shown) and send a signal indicating whether the locking pin 218 is so received to controller 190. The second locking proximity sensor (not shown) is positioned relative to the second locking pin hole (not shown) in a manner similar to that of the first proximity sensor 220 relative to the first locking pin hole 212.
[0061] Machine 100 can be configured to move the right rear outrigger 188 in various ways. For example, actuator 222 ( Figure 14-15(For example, a hydraulic cylinder) can be arranged to move the right rear outrigger 188 between a first (inner) position and a second (outer) position. In some embodiments, one or more sensors can be configured to detect the position of the right rear outrigger 188. For example, one or more sensors can be configured to detect the extension or retraction of the piston of actuator 222 and / or the rod attached to the piston, and controller 190 can be configured to determine the position of the right rear outrigger 188 based on signals from one or more sensors.
[0062] Controller 190, proximity sensors, and other components may be parts of system 224 configured to restrict the movement of operator station 102 in certain circumstances. Controller 190 controls the movement of operator station 102 and may reduce the range of movement of operator station 102 in certain circumstances, such as limiting the distance operator station 102 can move outside machine frame 186. Controller 190 may also prevent movement of operator station 102 and / or another movable part of machine 180 in certain circumstances. For example, in some embodiments, controller 190 is configured to restrict or prevent the movement of operator station 102 in response to the position of another movable part of machine 180.
[0063] The movable parts used to restrict the movement of operator station 102 can vary in different implementations. For example, any movable part that can be moved to a position that could interfere with the movement of the operator station can be used. In the illustrated embodiment, the position of the right rear support leg 188 is used. However, in other embodiments, different movable parts can be used, such as a service panel that can be opened on the floor or in another location, which could potentially damage the panel if the operator station moves while the service panel is open. Another example could be an access ladder to the operator station that can be moved, for example, from an entrance or exit. Furthermore, in some machines, movable devices used by the machine may interfere with the movement of the operator station in certain locations.
[0064] As described above and in some embodiments, this can be achieved by using an actuating member (e.g., actuating member 142) associated with operator station 102. Figure 5 The sensor device in the (e.g., sensor device 148) Figure 5The spatial location and / or position of operator station 102 can be determined based on information received from sensor devices (e.g., piston or rod extension, retraction amount, etc.). For example, information received from sensor devices can be used to determine the distance operator station 102 moves relative to machine 180 and / or the position of operator station 102 relative to machine 180. Controller 190 can use such information to limit the amount operator station 102 can extend from machine 180. In this way, operator station 102 can be prevented from moving too far outside the frame 186 of machine 180.
[0065] Figure 12-15 The operator station 102 and the right rear outrigger 188 are shown in various positions. (Reference) Figure 12 Operator station 102 is in the standard retracted position, such that the right outer wall or edge 230 of operator station 102 is flush with or inward relative to the transverse outer wall 187 of frame 186. In addition, the right rear support leg 188 is in the inner (first) position, such that the first locking pin hole 212 is aligned with the third locking pin hole 214 and the locking pin 218 is received through the first locking pin hole.
[0066] When the right rear outrigger 188 is in the inward (first) position and the locking pin 218 is received through the first locking pin hole 212, the first proximity sensor 220 detects the locking pin 218 and sends a signal indicating it to the controller 190. The controller 190 is configured not to restrict the movement of the operator station 102 based on the position of the right rear outrigger 188 when it is in the inward (first) position and the locking pin 218 is received through the first locking pin hole 212. Therefore, as Figure 13 As shown, operator station 102 can be moved laterally to a fully extended position, which is the full distance (i.e., range of motion) that operator station 102 can move outward beyond the lateral outer wall 187 of frame 186. Figure 13 The distance X is shown in the figure. For example, in one embodiment, the distance X of operator station 102 is greater than 200 mm or 215 mm.
[0067] refer to Figure 14 Operator station 102 is in the standard non-extended position (i.e., retracted position) such that the right outer wall or side edge 230 of operator station 102 is flush with or inward relative to the transverse outer wall 187 of frame 186. Right rear support leg 188 is in the outer (second) position such that the second locking pin hole (not shown) is aligned with the fourth locking pin hole 216 and the locking pin 218 is received through the second locking pin hole.
[0068] When the right rear outrigger 188 is in the outer (second) position and the locking pin 218 is received through the second locking pin hole, the second proximity sensor (not shown) detects the locking pin 218 and sends a signal indicating the presence of the locking pin 218 to the controller 190. The controller 190 is configured to restrict the movement of the operator station 102 according to the position of the right rear outrigger 188 when the right rear outrigger 188 is in the outer (second) position and the locking pin 218 is received through the second locking pin hole.
[0069] Therefore, as Figure 15 As shown, operator station 102 can move laterally outward beyond the lateral outer wall 187 of frame 186, limited only by a certain distance. Figure 15 The distance R is shown in the figure. For example, in one embodiment, the distance R is less than 70 mm or 65 mm. In some embodiments, the distance ratio between the full extension distance X and the limiting distance R is in the range of 2.8:1 to 3.8:1, or in the range of 3:1 to 3.5:1.
[0070] In some implementations, the controller 190 is configured to restrict movement of the operator station 102 at any time when the right rear outrigger 188 is not detected in the inner (first) position, regardless of whether the right rear outrigger 188 is fully in the outer (second) position. For example, when the right rear outrigger 188 is in the outer (second) position... Figure 12 The inner position shown is the same as Figure 14 At any position between the indicated outer positions, the controller 190 can restrict the movement of the operator station 102. Furthermore, the controller 190 can restrict the movement of the operator station 102 and / or prevent machine operation whenever the locking pin 218 is not detected to be in place through the first locking pin hole 212, even if the right rear support leg 188 is in the inner position. Therefore, if the locking pin 218 is not in place, the right rear support leg 188 can be considered to be in the outer position, and the movement of the operator station 102 is limited to an extension distance R. Additionally, in some embodiments, if the locking pin 218 is not installed, regardless of the position of the right rear support leg 188, the controller 190 can be configured to prevent machine operation, such as preventing machine movement, movement of the operator station 102, or operation of the milling system 194.
[0071] Similarly, controller 190 can prevent or restrict the movement of the right rear outrigger 188 based on the position of operator station 102. For example, if operator station 102 extends beyond a limit distance R, controller 190 can prevent the right rear outrigger 188 from moving from the inner (first) position. If operator station 102 extends but less than the limit distance R, controller 190 can allow the right rear outrigger 188 to move between the inner (first) position and the outer (second) position.
[0072] Industrial applicability
[0073] System 224 for restricting the movement of movable operator station 102 can be used in any machine having movable operator station 102 (e.g., machine 100, 180), such as a cold planer or rotary mixer. System 224 can determine the position of another movable part of the machine (e.g., right rear support leg 188) and restrict the movement of operator station 102 based on the position of the other part.
[0074] For example, such as Figure 16 As shown, at step 302, the method 300 for preventing interference between the movable operator station 102 of the mobile machine and the right rear support leg 188 or other movable components may include sending a signal indicating the position of the right rear support leg 188. At step 304, the controller 190 determines, based on the signal, whether the right rear support leg 188 is not in the inward position. If the right rear support leg 188 is not in the inward position, then at step 306, the controller 190 may limit the lateral outward movement of the operator station 102 from the retracted position to a second distance R, which is less than a first distance X. In this way, when the right rear support leg 188 is in the outward position, the operator station 102 is prevented from contacting the right rear support leg 188.
[0075] If the right rear outrigger 188 is indicated to be in the inward position, then at step 308, the controller 190 may not restrict the movement of the operator station 102. Therefore, if necessary, the operator station 102 can move laterally outward beyond the lateral outer wall 187 of the frame 186 to a fully extended position. In this way, the operator can be at least partially laterally positioned outside the lateral outer wall 187 of the frame 186, which improves the operator's visibility of the task being performed by the machine. Furthermore, positioning the operator outside the lateral outer wall 187 of the frame 186 reduces the amount of physical activity required for the operator to obtain a satisfactory task view, thus reducing operator fatigue.
[0076] like Figure 17 As shown, the method 300 for preventing interference between the movable operator station 102 and the right rear outrigger 188 or another movable member can also be based on the position of the operator station 102. For example, at step 310, method 300 may include sending a signal indicating the position of the operator station 102. At step 312, controller 190 determines whether the operator station 102 is laterally outward from the retracted position at a distance greater than a second distance R. If the operator station 102 is laterally outward from the retracted position at a distance greater than the second distance R, then at step 314, controller 190 may prevent the right rear outrigger 188 from moving from the inner position to the outer position. In this way, when the operator station 102 extends laterally, the right rear outrigger 188 is prevented from contacting the operator station 102.
[0077] At step 316, if operator station 102 indicates a distance less than the second distance laterally outward from the retracted position, or is in the retracted position, controller 190 may not prevent the right rear outrigger 188 from moving to the outward position.
