Definitions

  • the present invention relates generally to industrial machines. More specifically, the present invention relates to surface treatment machines with a supplemental drive for rotation of a rotor for inspection, maintenance, or testing purposes, as well as methods of manufacturing and operating the same.
  • Industrial machines may include mounted work drums that contact a surface over which the industrial machine is operating. These industrial machines may include milling machines or cold planers designed to prepare or treat a surface such as a road surface, pavement, soil, or earth.
  • the work drum which may have a coarse surface or attachments protruding from its surface, is rotationally driven by a motor that forms part of a drive train that includes a series of pulleys connected by a drive belt that is used to rotate the work drum so that it contacts the surface with a force sufficient to alter, treat, or even remove the surface to a predetermined depth.
  • For operations such as milling a paved road surface, where the work drum contact with the road surface results in destruction and removal of the asphalt, it is plain to see that significant force is required and that the work drum comes into powerful contact with the surface.
  • the auxiliary drive of Busley is not without drawbacks.
  • the auxiliary drive must be coupled to the drive train. Therefore problems may arise due to failures in the coupling process, resulting in a failure to properly drive the work drum. Insufficient coupling of the auxiliary motor to the drive train can result in unwanted slippage which leads to unpredictable rotation of the work drum. This increases the time required for maintenance operations and reduces the time in which the machine is available to operate properly, resulting in inefficient overall operation and increased cost.
  • the present invention is directed to overcoming one or more of the problems as set forth above.
  • the invention includes a chassis mounted to a drum rotor.
  • a drive motor is also mounted to the chassis, and the drive motor may be coupled to a drive train that includes a drive pulley.
  • the drive motor is capable of being adapted to drive the drive pulley. When the drive motor is activated, it drives the drive pulley to rotate the drum rotor at a first rotational velocity.
  • the surface treatment machine may also include a service motor integral to the drive pulley. The service motor is capable of being adapted to drive the drive pulley to rotate the drum rotor at a second rotational velocity when the service motor is activated.
  • a method of manufacturing a surface treatment machine that includes providing a chassis with a drive motor mounted to the chassis.
  • the method of manufacturing also includes coupling a drum rotor to the drive motor with a drive train that includes a drive pulley, and adapting the drive motor to the drive pulley to rotate the drum rotor at a first rotational velocity when the drive motor is activated.
  • the method includes integrating a service motor into the drive pulley, and adapting the service motor to the drive pulley to rotate the drum rotor at a second rotational velocity when the service motor is activated.
  • the invention may be embodied in surface treatment machines including at least one drum rotor that may be dependably and precisely controlled for analysis and maintenance purposes, as well as methods of manufacturing, operating, and maintaining the same. These products and methods enable inspection and repairs by one or more operators.
  • Embodiments of the invention may be implemented in surface treatment machines without increasing their overall footprint.
  • Figure 1 is a profile view of a surface treatment machine 100 with the drum rotor and drive train visible.
  • Surface treatment machine 100 is generally an industrial vehicle designed to engage a surface 105. Typically surface 105 is altered, rendered uniform, or otherwise treated upon engagement with surface treatment machine 100.
  • Surface treatment machine 100 may include cold planer machines, milling machines, soil stabilizer machines, road reclaimer machines, surface mining machines, or other machines that include one or more drive systems.
  • Surface 105 typically includes pavement, asphalt, concrete, soil, earth, stone, any form of road surface, or any combination of these and other similar materials.
  • Surface treatment machine 100 generally includes a chassis 110, which itself generally encompasses all frames, wheels, and machinery of surface treatment machine 100. Chassis 110 may be raised or lowered with respect to surface 105. Surface treatment machine 100 also generally includes a front tread 115 and a rear tread 120, which are both typically continuous metal belts in rolling contact with surface 105 as surface treatment machine 100 moves along surface 105. Front tread 115 and rear tread 120 may include any type of belt, tire, or wheel that provides sufficient traction to allow proper movement of surface treatment machine 100.
  • Drum rotor 125 which is typically a cylindrically shaped object, is generally located between front tread 115 and rear tread 120.
  • the outer surface of drum rotor 125 generally contacts surface 105 during operation.
  • This outer surface may be generally smooth, however according to other embodiments, drum rotor 125 may include a coarse or uneven outer surface, and the outer surface may include protrusions or indentations of varying size or shape that are formed as part of its outer surface.
  • Drum rotor 125 is capable of rotation and typically contacts surface 105 during normal operation.
  • drum rotor 125 may be raised or lowered with respect to surface 105 so that it may penetrate beneath surface 105 to a depth sufficient to perform the desired treatment operations.
  • Drum rotor 125 may be raised above surface 105 for inspection or maintenance purposes.
  • chassis 110 may be raised or lowered in order to raise or lower drum rotor 125 with respect to surface 105.
  • drum rotor 125 may penetrate several inches or more (dozens of centimeters or more) below surface 105.
  • surface treatment machine 100 is generally in forward motion over surface 105 with drum rotor 125 situated a predetermined depth below surface 105.
  • drum rotor 125 is rotating and comes into contact with surface 105 as surface treatment machine 100 advances. This contact between drum rotor 125, which is rotating about its axis, advancing forward at the forward operating speed of surface treatment machine 100, and is submerged a predetermined depth below surface 105, is sufficient to pulverize the pavement to the predetermined depth.
  • drum rotor 125 may include a plurality of surface treatment tools 130.
  • Surface treatment tools 130 are generally attachable and removable protrusions such as a plurality of teeth that extend from the outer surface of drum rotor 125.
  • Surface treatment tools 130 may be placed randomly or in any pattern on the outer surface of drum rotor 125.
  • Figure 1 depicts surface treatment tools 130 extending uniformly around the entire outer surface of drum rotor 125.
  • surface treatment tools 130 may cover all or only a portion of this outer surface, and may be differently shaped to protrude to varying distances and be spaced in varying patterns about the outer surface of drum rotor 125.
  • surface treatment tools 130 engage surface 105 during operation to, for example, facilitate pavement milling or otherwise treat surface 105.
  • Drum rotor 125 is generally driven by a drive train that drives drum rotor 125 so that it rotates around its longitudinal axis.
  • the drive train ordinarily includes at least one drive motor 135 shown schematically in Figure 1 , at least one coupler 140, and at least one motor pulley 145.
  • the drive train also generally includes a drive pulley 150, a service motor 155, and a belt 160.
  • drive motor 135 is operationally coupled by a coupler 140 to a motor pulley 145.
  • drive motor 135 may be coupled to any other components of the drive train, such as belt 160 for example.
  • the drive train generally includes all of the components that enable rotation of drum rotor 125.
  • drum rotor 125, surface treatment tools 130, drive motor 135, coupler 140, motor pulley 145, drive pulley 150, service motor 155, belt 160 and other drive train components such as a belt drive are generally within chassis 110 or protruding beneath surface 105, and thus are typically not visible externally.
  • these elements may be covered by a detachable panel that forms part of chassis 110.
  • first rotational velocity of drum rotor 125 may vary, and is generally any rotational velocity sufficient for proper treatment of surface 105.
  • first rotational velocity is generally a rotational velocity sufficient for drum rotor 125 to pulverize the pavement.
  • first rotational velocity is approximately 30rpm, however this rotational velocity can vary widely, for example, from a few to hundreds of revolutions per minute.
  • surface treatment machine 110 when surface treatment machine 110 includes drum rotor 125 operating at a first rotational velocity, surface treatment machine 110 is in the process of treating a surface. In such a case, surface treatment machine 110 may be referred to as being in an operational state.
  • the first rotational velocity is generally the rotational velocity of drum rotor 125 when it is being driven by drive motor 135, i.e. when drive motor 135 is activated.
  • the first rotational velocity drum rotor 125 When in an operational state, the first rotational velocity drum rotor 125 is generally not a suitable velocity to inspect or perform maintenance on drum rotor 125 of the surrounding area of surface treatment machine 110. Typically, the first rotational velocity is too high to use when inspecting or performing maintenance on drum rotor 125.
  • Servicing drum rotor 125 for example to replace surface treatment tools 130 or to remove debris stuck between surface tools 130, is generally not possible at the first, or operational, rotating velocity. However, it is generally necessary to rotate drum rotor 125 for service or inspection purposes, as only a portion of drum rotor 125 is accessible at a given time. Using drive motor 135 to rotate drum rotor 125 for any non-operational purpose, such as for servicing, inspection, or maintenance would be difficult.
  • surface treatment machine 110 generally includes service motor 155.
  • Service motor 155 may be an electric motor, an induction motor, a hydraulic motor, or other device that converts electrical energy into mechanical energy or outputs mechanical energy.
  • Service motor 155 is generally part of the drive train and provides the mechanical energy to rotate rotor drum 125 when service motor 155 is activated.
  • service motor 155 When service motor 155 is active, it generally drives drum rotor 125 at a second rotational velocity.
  • This second rotational velocity may also be referred to as a service rotational velocity.
  • the second rotational velocity is typically different than the first rotational velocity.
  • the second, or service, rotational velocity is less than the first, or operational, rotational velocity.
  • the second rotational velocity may vary, but for example may be less than 15rpm. In one embodiment, the second rotational velocity is approximately 3rpm.
  • the second rotational velocity is generally sufficient to allow a service technician to inspect or perform maintenance operations on all or a portion of drum rotor 125 and the surrounding area.
  • the maximum output of service motor 155 may result in a maximum second rotational velocity that remains sufficient for the performance of inspection or maintenance operations. In this situation any unintended spike in service motor 155 power output is either not possible or would result in little or no increase in the second rotational velocity.
  • the maximum power output of service motor 155 is sufficient only to overcome the inertia associated with drum rotor 125 and rotate drum rotor 125 at a constant but low speed relative to the first rotational velocity, such as for example 3rpm.
  • the maximum power output is ultimately dependent on the desired functionality of service motor 155.
  • Service motor 155 may also be controlled by a service technician who is performing a service operation on or near drum rotor 125, to partially rotate drum rotor 125.
  • drum rotor 125 could be rotated at the second rotational velocity for 30 degrees, at which point service motor may be turned off, deactivated, or otherwise disengaged from the drive train so that drum rotor 125 stops rotating.
  • service motor 155 could again be activated to rotate drum rotor at the second rotational velocity another 30 degrees before stopping again to enable inspection or replacement of another segment of surface treatment tools 130.
  • the amount drum rotor 125 is rotated may be determined by the operator while drum rotor 125 is being rotated. In one embodiment, the amount drum rotor 125 is rotated may be determined based on a predetermined rotational distance, time of rotation at a rotational velocity, or angle of rotation relative to the axis of drum rotor 125.
  • the motor whose power output is driving drum rotor 125 rotation at any point in time is the motor deemed to be activated.
  • the motor deemed to be activated typically, only one of drive motor 135 and service motor 155 is activated at any one time.
  • typically only one of these motors is engaged with the drive train. In such a case the engaged motor is the activated motor and the power generated by the motor that is not engaged with the drive train does not effect drum rotor 125 rotation.
  • service motor 155 may be integral to or embedded within drive pulley 150.
  • drive pulley 150 may be cylindrical in shape and hollow, and service motor 155 may be located within the inner diameter of drive pulley 150, or within a cylinder formed by the inner diameter of drive pulley 150 and extending along the longitudinal axis of drive pulley 150.
  • service motor 155 may be machined into or otherwise permanently affixed as an inseparable part of drive pulley 150 to form a single unit. In these embodiments, service motor 155 may directly engage either drum rotor 125 or the inner surface of drive pulley 150 in order to rotate drum rotor 125 at a second rotational velocity.
  • This direct engagement ensures a reliable second rotational velocity and reduces power losses or drive train slippage associated with additional coupling mechanisms, which facilitates service operations. Additionally, in one embodiment, the addition of service motor 155 integral to drive pulley 150 does not change the overall footprint of surface treatment machine 105.
  • a service technician may manually engage and disengage a drive connection between service motor 155 and drum rotor 125. This may include connecting service motor 155 to a rotor input shaft of drum rotor 125. In one embodiment, service motor 155 may be connected to a rotor input shaft of drum rotor 125 by use of a freewheeling device.
  • a freewheeling device generally allows for engagement and disengagement between service motor 155 and drum rotor 125 without manual service technician intervention. In one embodiment, the freewheeling device may also prohibit power output from service motor 155 or drive motor 135 from driving drum rotor 125 unless one of service motor 155 and drive motor 135 is activated.
  • the freewheeling device may disengage service motor 155 to prevent it from transferring its mechanical power output to drum rotor 125 if that mechanical power output is higher than a predetermined threshold. This generally prevents the second rotational velocity of drum rotor 125 from exceeding a predetermined velocity, minimizing the chance of unpredicted changes in the second rotational velocity.
  • the rotor input shaft of drum rotor 125 is typically rotating faster than it rotates in situations where service motor 155 is activated and drum rotor 125 is rotating at the second rotational (service) velocity.
  • the power output from drive motor 135 is generally greater than the power output from service motor 155.
  • the freewheeling device or a service technician operating manually may disengage service motor 155 from drum rotor 125 so that only power from drive motor 135 is driving drum rotor 125 at the first operational velocity.
  • the freewheeling device or a service technician operating manually may disengage drive motor 135 so that only power from service motor 155 is used and drum rotor 125 is operating at the second rotational velocity.
  • drive motor 135 When drive motor 135 is activated, service motor 155 may be turned off. In this case, any residual power output from service motor 155 may be disengaged from drum rotor 125 by the freewheeling device or a service technician.
  • Belt 160 is typically a flexible band that generally passes about at least motor pulley 145 and drive pulley 150 to transmit motion from drive motor 135 or service motor 155 to drum rotor 125.
  • Belt 160 may include grooves to provide increased traction and prevent slippage when belt 160 contacts motor pulley 145 or drive pulley 160.
  • Control panel 165 generally controls operation of any drive train components such as service motor 155 to rotate drum rotor 125 at the second rotational velocity for inspection or servicing. Control panel 165 may also control operation of drive motor 135. Control panel 165 is typically located within chassis 110 in the vicinity of drum rotor 125 so that a service technician may operate any drive train components during servicing, or inspection. Alternatively, control panel 165 may be located on the external chassis 110 surface, remotely from surface treatment machine 100, or near operator cavity 170, which is the space where a human is normally positioned to operate surface treatment machine 100.
  • Figure 2 is a schematic diagram depicting a system 200 for the drive train in accordance with an embodiment of the invention.
  • the drive train may generally include all components such as motors, pulleys and belts related to the driving of drum rotor 125.
  • System 200 includes plate 205, which may be included as part of chassis 110 upon which drive motor 135 is mounted.
  • System 200 includes drive motor 135, motor pulley 145, and drive pulley 150.
  • Service motor 155 (not shown) may be integral to drive pulley 150.
  • Belt tensioning device 210 may include a pneumatic or hydraulic pump, motor, or other mechanical device designed to maintain a desired tension in belt 160 (not shown) where belt 160 is generally looped around motor pulley 145, drive pulley 150, and belt tensioning device 210.
  • Belt 160 is typically operationally coupled to motor pulley 145, drive pulley 150, and belt tensioning device 210 so that belt 160 circulates when any of motor pulley 145, drive pulley 150, belt 160, or belt tensioning device 210 are rotationally driven.
  • panel 215 typically surrounds the drive train in general, and more specifically may laterally surround belt 160. In various embodiments, panel 215 may be considered part of plate 205 or chassis 110. Panel 215 generally acts to prevent debris from interfering with the function of any of the drive train components, such as belt 160, drive pulley 150, service motor 155, motor pulley 145, coupler 140, or drive motor 135, for example.
  • system 200 may be covered by a cover plate (not shown).
  • a cover plate, along with plate 205 and panel 215 may be part of chassis 110 and typically shields the entire drive train from external view, thus reducing exposure to debris and other elements such as rain.

  • Integrating step (STEP 720) may include affixing a service motor inside the inner diameter of the drive pulley so that the service motor and the drive pulley may in some embodiments form a single inseparable unit so that the service motor, when activated, directly drives the drive pulley. Alternately, the service motor may directly drive the drum rotor.
  • integrating a service motor into the drive pulley may include fastening a service motor to any portion of the drive pulley, or within a cylinder whose diameter corresponds to the cylinder formed by the inner diameter of the drive pulley and extends along the longitudinal axis of the drive pulley, with or without intervening coupling elements, such as bolts or fasteners so that service motor, when activated, effects drum rotor rotation in a controlled manner.
  • Method 700 also generally includes the step of adapting the service motor to drive the drive pulley to rotate the drum rotor at a second rotational velocity when the service motor is activated (STEP 725).
  • Adapting step (STEP 725) typically includes engaging the service motor with the drive train so that the power output of the service motor is used to rotate the drum rotor at a second rotational velocity when the service motor is activated.
  • the drive motor may include an operator such as a service technician manually engaging the service motor with an input shaft of the drum rotor.
  • adapting (STEP 725) may include connecting the service motor with an input shaft of the drum rotor (STEP 730).
  • Connecting step (STEP 730) may be accomplished by use of a freewheeling device.
  • both adapting step (STEP 725) and connecting step (STEP 730) may include engaging the service motor to any component of the drive train, such as a belt or a motor pulley by means of any of a fasteners, clips, nuts, bolts, screws, clamps, pin locks, friction, pressure, or an adhesive.
  • method 700 may also include providing a control panel (STEP 735) enabling a user, such as an operator, to activate at least one of the drive motor and the service motor to operate the surface treatment machine at one of the first rotational velocity and the second rotational velocity. In this illustrative embodiment, it is specifically the drum rotor that is rotating at one of the first rotational velocity and the second rotational velocity.
  • Method 700 may also include fastening the control panel to the chassis (STEP 740).
  • Fastening step (STEP 740) typically includes fastening by any means previously described as fastening means, such as bolts, rivets, screws, pin locks, or various adhesives for example.
  • Method 700 may also include providing a plurality of surface treatment tools (STEP 745) capable of attachment to the drum rotor.
  • Providing the surface treatment tools (STEP 745) may include manufacturing or assembling the surface treatment tools from raw materials, or otherwise making surface treatment tools available to the surface treatment machine.
  • references signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, neither the reference signs nor their absence have any limiting effect on the technical features as described above or on the scope of any claim elements.
