Description

Technical Field

[0001] This invention belongs to the field of metal parts testing technology, specifically, it relates to a processing and testing equipment and method for steel materials used in power transmission towers. Background Technology

[0002] U-shaped flat steel on power transmission line towers is an important structural element, mainly used to enhance the overall stability and connection performance of the tower. In tower design, U-shaped flat steel is often used to fix and support various components, such as crossarms, diagonal members and insulator strings. Its unique U-shaped structure allows it to wrap around round or square members, providing reliable connection points, thereby distributing loads and stresses and preventing components from loosening or shifting.

[0003] After the U-shaped flat steel is processed, the workers need to test its surface flatness to ensure that it meets the design specifications. During the test, the workers first clean the surface of the U-shaped flat steel to remove oil, iron filings or other impurities to avoid affecting the test results. Then, the U-shaped flat steel is placed on a flat and stable testing platform, which is usually made of metal or stone and has a precision-machined surface to ensure its flatness. Next, the workers use a dial indicator as the main tool, gently placing it against each surface of the U-shaped flat steel, paying particular attention to its long sides and curved parts. By carefully observing the dial indicator readings, the workers can make a preliminary judgment on the surface flatness of the workpiece.

[0004] However, for long U-shaped flat steel workpieces, when adjusting the dial indicator's testing points along the workpiece's length, the operator needs to zero the dial indicator and re-establish and fix it each time. That is, at each new testing point, the operator must use a nearby reference point (or a temporary benchmark) as the new "zero point" and recalibrate the dial indicator. The entire testing process is frequently interrupted and divided into multiple segments: moving the dial indicator base, carefully cleaning the new positioning surface, re-attaching and fixing it, carefully clamping the dial indicator, finely adjusting it to the probe preload, and then rotating the dial for zeroing. This series of actions needs to be repeated dozens of times or even more when testing long workpieces, consuming a lot of time and manpower, and seriously slowing down the pace of production or quality inspection. Moreover, each zeroing and fixing is an independent manual operation. The operator's feel, strength, judgment, and even fatigue level will affect the accuracy of zeroing and the stability of the dial indicator fixing, so that the measured values ​​at different points are actually obtained under slightly different "benchmarks," thus affecting the objectivity of the flatness evaluation over the entire length. Summary of the Invention

[0005] The purpose of this invention is to provide a processing and testing equipment and method for steel materials used in power transmission towers. Two long U-shaped flat steel workpieces to be tested are placed parallel to each other on the left and right sides of the top of a set of rollers. Then, the U-shaped flat steel workpieces are clamped and limited in the width direction by a counter-positioning limit assembly. The dual-axis linear drive assembly adjusts the position of the dual-station roller synchronous feeding assembly according to the specifications of the U-shaped flat steel workpieces. The dual-station roller synchronous feeding assembly drives the two long U-shaped flat steel workpieces to move smoothly along their length direction. During the movement, a calibrated and fixed digital dial indicator measures the surface flatness of the moving workpieces in real time until the entire workpiece is measured, thereby solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A processing and testing device for steel for power transmission towers includes a roller frame. A partition plate is fixedly installed at the vertical center reference plane at the top of the roller frame. Multiple support rollers are rotatably installed on the partition plate. Several vertical side rollers are rotatably installed at equal intervals on the left and right outer walls of the partition plate. An opposing limit assembly for pushing U-shaped flat steel close to the vertical side rollers is installed inside the roller frame. Digital dial indicators are installed on both outer walls of the partition plate. An adjustment frame for adjusting the position of the digital dial indicators is installed at the top of the partition plate.

[0008] The top of the roller frame is equipped with a dual-axis linear drive assembly. The drive end of the dual-axis linear drive assembly is equipped with a dual-station roller synchronous feeding assembly for driving two U-shaped flat steel bars to move synchronously along the length direction. A control panel is installed on one side of the outer wall of the roller frame. The output end of the control panel is electrically connected to the input end of the dual-axis linear drive assembly and the dual-station roller synchronous feeding assembly, respectively.

[0009] The following are further optimizations of the above technical solution by the present invention:

[0010] The dual-axis linear drive assembly includes a T-shaped upright fixedly installed at the center of the top of the roller frame. A left slide and a right slide are symmetrically slidably installed on the outer wall of the T-shaped upright near the partition plate. A bidirectional screw electric linear module for driving the left and right slides to move in opposite directions is installed on the outer wall of the T-shaped upright. The input end of the bidirectional screw electric linear module is electrically connected to the output end of the control panel.

[0011] Further optimization: The left and right slides are each equipped with a vertically sliding carriage on the outer wall of the side away from the T-shaped support. The dual-station roller synchronous feeding assembly is installed on the two carriages respectively. An electric push rod is installed at the top of the right slide to drive one of the carriages to slide vertically. The input end of the electric push rod is electrically connected to the output end of the control panel.

[0012] Further optimization: Hollow square tubes and square arms are integrally formed on the outer walls of the left and right slides that are close to each other, and one end of the square arm slides into the interior of the hollow square tube.

[0013] Further optimization: The dual-station roller synchronous feeding assembly includes a bearing platform fixed to the bottom of the carriage. Multiple plate-type rubber wheels are rotatably mounted on the outer walls of the two bearing platforms that are far apart from each other. Splined shafts and keyway shafts are rotatably mounted on the outer walls of the opposite sides between the two bearing platforms. The ends of the splined shafts and keyway shafts that are close to each other slide and are connected by transmission. A rotary drive unit for driving the keyway shaft and splined shaft to rotate synchronously is installed on the outer wall of one of the bearing platforms.

[0014] Further optimization: The rotary drive unit includes a servo motor and a belt drive structure. The servo motor is fixedly mounted on the shaft carrier, and its output shaft is connected to one end of the spline shaft. The keyway shaft and the spline shaft drive multiple plate-type rubber wheels to rotate together through the belt drive structure.

[0015] Further optimization: The opposing limiting assembly includes a support platform fixedly installed inside the roller frame. C-port sliding arms are slidably installed at the left and right positions of the bottom end of the support platform. A bidirectional screw manual adjustment module is installed at the bottom end of the support platform. The bidirectional screw manual adjustment module is used to drive the two C-port sliding arms to move towards each other or away from each other.

[0016] Further optimization: The top of the C-port sliding arm extends through to the top of the roller frame and is fixed with a roller carrier platform. A vertical side roller is rotatably installed on the outer wall of the roller carrier platform near the partition plate.

[0017] Further optimization: Both the second vertical side roller and the first vertical side roller are made of stainless steel.

[0018] This invention also provides a processing and testing method for steel used in power transmission towers, and based on the above, a processing and testing device for steel used in power transmission towers, comprising the following steps:

[0019] S101: Place two long U-shaped flat steel workpieces to be inspected stably above multiple rollers. According to the specific specifications of the U-shaped flat steel, start the opposing limit assembly to limit and clamp the workpieces in the width direction. Start the dual-axis linear drive assembly on the control panel. The dual-axis drive assembly adjusts the position of the dual-station roller synchronous feeding assembly so that the position of the dual-station roller synchronous feeding assembly matches the position of the workpiece to be transferred.

[0020] S102: Install the digital micrometer at the fixed position on the top of the partition plate using the adjustment bracket, so that the probe of the digital micrometer is perpendicular to and in contact with the detection point on the surface of the U-shaped flat steel to be measured, and then zero the digital micrometer, which serves as the reference point for the entire measurement process.

[0021] S103: Start the dual-station roller synchronous feeding assembly through the control panel to drive two U-shaped flat steel workpieces to pass smoothly and at a constant speed along their length through the measurement area of ​​the digital micrometer. The probe continuously contacts the workpiece surface. As the workpiece moves, the microscopic height change of the workpiece surface relative to the initial zero point is monitored and recorded in real time.

[0022] S104: After the entire U-shaped flat steel workpiece has completely passed the measuring point of the digital dial indicator, shut down the dual-station roller synchronous feeding assembly, and then analyze the measured value on the digital dial indicator to determine whether the surface flatness of the workpiece meets the requirements.

[0023] The present invention, by adopting the above technical solution, has at least the following beneficial effects:

[0024] 1. This invention has two detection positions, which can simultaneously place two long U-shaped flat steel workpieces to be inspected parallel to each other on the rollers. Then, the opposing limiting assembly limits the U-shaped flat steel workpieces in the width direction. The dual-axis linear drive assembly adjusts the position of the dual-station roller synchronous feeding assembly according to the specifications of the U-shaped flat steel workpieces. The dual-station roller synchronous feeding assembly drives the two long U-shaped flat steel workpieces to move smoothly along their length direction. During the movement, a calibrated and fixed digital micrometer measures the surface flatness of the moving workpieces in real time until the entire workpiece is measured. Thus, by combining dual-station synchronous conveying and fixed measuring instruments, efficient and high-quality surface flatness inspection of long U-shaped flat steel workpieces is achieved.

[0025] 2. This invention achieves simultaneous dual-station synchronous inspection, enabling the simultaneous measurement of two U-shaped flat steel workpieces. The dual-station roller-type synchronous feeding assembly allows for continuous and stable longitudinal movement of the workpieces, replacing the repetitive movement and fixing of the dial indicator by the operator. The measurement process is no longer interrupted by frequent interruptions, forming a continuous assembly line operation, thus greatly shortening the overall inspection time for a single workpiece. Secondly, in traditional methods, each re-clamping and zeroing of the dial indicator varies depending on the operator's feel, force, and judgment, introducing variables that cannot be precisely quantified. This solution uses a calibrated and fixed-state digital dial indicator for measurement, ensuring the stability and accuracy of the measurement data. Because the dial indicator is in a fixed state, it avoids the measurement errors caused by frequent movement and re-zeroing in traditional inspections, effectively improving the accuracy and reliability of the measurement results.

[0026] 3. In this invention, the two workpieces are driven by a dual-station roller synchronous feeding assembly and move smoothly on the rollers, reducing uncertainties caused by vibration and displacement, making the surface flatness measurement more accurate. The opposing limit assembly positions the workpiece in the width direction, ensuring the positional stability of the workpiece during the measurement process, further avoiding lateral deviation of the workpiece, and ensuring the consistency of measurement points and the continuity of data.

[0027] 4. In this invention, the workpiece is continuously measured while it is moving. The digital dial indicator can collect continuous data points, thereby accurately depicting the flatness change trend, wave deformation or slight bending of the workpiece along its entire length, making it easier for workers to judge the flatness of the workpiece.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] like Figure 1-8 As shown, a processing and testing device for steel used in power transmission towers includes a roller frame 1. A partition plate 2 is fixedly installed at the vertical center reference plane at the top of the roller frame 1. Multiple idler rollers 3 are rotatably installed on the partition plate 2. The multiple idler rollers 3 are spaced apart along the length direction of the partition plate 2, and the length extension direction of the partition plate 2 is perpendicular to the axial extension direction of the idler rollers 3. The two ends of the idler rollers 3 are respectively rotatably installed on the inner side of the roller frame 1. Several vertical side rollers 4 are rotatably installed on the left and right outer walls of the partition plate 2 at equal intervals through bearing seats. The vertical side rollers 4 are positioned between two adjacent idler rollers 3. An opposing limiting assembly 5 for pushing U-shaped flat steel close to the vertical side rollers 4 is installed inside the roller frame 1. Digital display dial indicators 9 are installed on both outer walls of the partition plate 2. An adjusting frame 8 for adjusting the position of the digital display dial indicators 9 is installed at the top of the partition plate 2.

[0039] In this embodiment, the stability of the roller frame 1 ensures the stability of the installation and operating environment of all subsequent equipment, effectively reducing measurement errors caused by vibration or structural deformation. The idler roller 3 is installed in the middle of the roller frame 1 to bear the load and transport of the workpiece, so that the long U-shaped flat steel workpiece can roll smoothly during the inspection process, reducing frictional resistance and vibration. The partition plate 2 divides the upper end face of the roller frame 1 into two inspection stations, and the two inspection stations can simultaneously perform moving inspection operations on the two U-shaped flat steel workpieces, thereby preventing the two workpieces from colliding or interfering with each other during the transport process and improving inspection efficiency.

[0040] In this embodiment, the adjustment frame 8 consists of a rod, a sliding sleeve, and a locking bolt, and is used to adjust the height and lateral position of the digital micrometer 9, thereby ensuring that the measuring probe maintains good contact with the workpiece surface and ensuring the accuracy of the measurement.

[0041] like Figure 1-2 As shown, a dual-axis linear drive assembly 6 is installed at the top of the roller frame 1, and a dual-station roller-type synchronous feeding assembly 7 is installed at the drive end of the dual-axis linear drive assembly 6 to drive two U-shaped flat steel bars to move synchronously along the length direction.

[0042] A control panel 10 is installed on one outer wall of the roller frame 1. The output end of the control panel 10 is electrically connected to the input end of the dual-axis linear drive assembly 6 and the dual-station roller synchronous feeding assembly 7, respectively. By outputting independent control signals, the control panel 10 can control the dual-axis linear drive assembly 6 and the dual-station roller synchronous feeding assembly 7 to work independently, or control them to work together.

[0043] like Figure 5 and Figure 6 As shown, the dual-axis linear drive assembly 6 includes a T-shaped upright 601 fixedly installed at the center of the top of the roller frame 1. A left slide 603 and a right slide 604 are symmetrically slidably installed on the outer wall of the T-shaped upright 601 near the partition plate 2. A bidirectional lead screw electric linear module 602 for driving the left slide 603 and the right slide 604 to move in opposite directions is installed on the outer wall of the T-shaped upright 601.

[0044] The input terminal of the bidirectional lead screw electric linear module 602 is electrically connected to the output terminal of the control panel 10. The control panel 10 outputs a control signal to control the bidirectional lead screw electric linear module 602 to work. At this time, the bidirectional lead screw electric linear module 602 controls the left slide 603 and the right slide 604 to move towards or away from each other according to the control signal, so as to adjust the position between the left slide 603 and the right slide 604.

[0045] The left slide 603 and the right slide 604 are each equipped with a slide 605 that can slide vertically on the outer wall of the side away from the T-shaped support 601. The dual-station roller synchronous feeding assembly 7 is installed on the two slides 605 respectively.

[0046] The top of the right slide 604 is equipped with an electric push rod 606 for driving one of the slides 605 to slide vertically. The input end of the electric push rod 606 is electrically connected to the output end of the control panel 10.

[0047] In this design, to ensure that the dual-station roller synchronous feeding assembly 7 can contact the workpiece, the operator activates the electric push rod 606 through the control panel 10. The electric push rod 606 drives the slide 605 and the dual-station roller synchronous feeding assembly 7 to move down until the roller part of the dual-station roller synchronous feeding assembly 7 can contact the workpiece.

[0048] Hollow square tube 6031 and square arm 6041 are integrally formed on the outer wall of the left slide 603 and the right slide 604 respectively, which are close to each other. One end of the square arm 6041 slides into the interior of the hollow square tube 6031.

[0049] Two dovetail guide rails are mounted on one side of the T-shaped support 601 and the dovetail guide rails are mounted on the back of the left slide 603 and the right slide 604. Sliding sleeves that slide with the dovetail guide rails are installed on the back of the left slide 603 and the right slide 604. Through the sliding engagement between the sliding sleeves and the dovetail guide rails, the left slide 603 and the right slide 604 are slidably mounted on the T-shaped support 601, providing precise guidance for the translation of the left slide 603 and the right slide 604.

[0050] With this design, when the operator uses the dual-axis linear drive assembly 6 to adjust the position of the dual-station roller synchronous feeding assembly 7, they can activate the bidirectional screw electric linear module 602 via the control panel 10. The bidirectional screw electric linear module 602 drives the left slide 603 and the right slide 604 to move towards each other. Taking the left slide 603 and the right slide 604 as moving closer to each other as an example, at this time, the two slides 605 in the linear movement direction of the bidirectional screw electric linear module 602 move closer to each other, so that the dual-station roller synchronous feeding assembly 7 can be adjusted according to the position of the two workpieces.

[0051] In this embodiment, the bidirectional lead screw electric linear module 602 is prior art, and its specific structure includes a lead screw, which is rotatably mounted on a T-shaped support 601. The lead screw has two threaded sections, and threaded blocks are threadedly connected to the two threaded sections respectively. The two threaded blocks are fixedly connected to the corresponding left slide 603 and right slide 604 respectively. One end of the lead screw is driven by a drive motor, which is fixedly mounted on the T-shaped support 601.

[0052] like Figure 5-6 As shown, the dual-station roller synchronous feeding assembly 7 includes a shaft carrier 703 fixed to the bottom of the slide 605. Multiple plate-type rubber wheels 705 are rotatably mounted on the outer walls of the two shaft carriers 703 that are far apart from each other. A spline shaft 702 and a keyway shaft 701 are rotatably mounted on the outer walls of the opposite sides between the two shaft carriers 703. The ends of the spline shaft 702 and the keyway shaft 701 that are close to each other slide and are connected in transmission. A rotary drive unit for driving the keyway shaft 701 and the spline shaft 702 to rotate synchronously is installed on the outer wall of one of the shaft carriers 703.

[0053] In this embodiment, multiple plate-type rubber wheels 705 are arranged at intervals along the length direction of the corresponding axle carrier 703; this makes the workpiece more evenly stressed during the conveying process and avoids excessive local friction that could cause damage to the workpiece surface or conveying deviation.

[0054] The rotary drive unit includes a servo motor 704 and a belt drive structure 706. The servo motor 704 is fixedly mounted on the shaft carrier 703. The output shaft of the servo motor 704 is connected to one end of the spline shaft 702. The keyway shaft 701 and the spline shaft 702 drive multiple plate-type rubber wheels 705 to rotate together through the belt drive structure 706.

[0055] In this embodiment, tensioning wheels 707 are respectively installed on one outer wall of the shaft carrier platform 703. The tensioning wheels 707 are used to press against the belt drive structure 706 to improve the transmission effect.

[0056] With this design, the keyway shaft 701 and spline shaft 702 can extend and retract accordingly based on the moving distance of the bidirectional ball screw electric linear module 602. At this time, the keyway shaft 701 and spline shaft 702 maintain continuous power connection. When the servo motor 704 starts to drive the keyway shaft 701 and spline shaft 702 to rotate, both the keyway shaft 701 and spline shaft 702 drive the plate rubber wheel 705 on their respective sides to rotate through the belt drive structure 706. The plate rubber wheel 705 drives the workpiece to move along the length direction until it passes through the detection area where the digital display dial indicator 9 is located.

[0057] The dual-station roller synchronous feeding assembly 7 and the dual-axis linear drive assembly 6 work together to complete the task of conveying workpieces. They can drive two workpieces to move forward synchronously at the same time, realizing efficient multi-workpiece inspection operation. The multi-roller design effectively improves the stability and reliability of conveying.

[0058] In this embodiment, the belt drive structure 706 may be one of a pulley, a belt drive assembly, or a synchronous pulley and a synchronous belt drive assembly.

[0059] In addition to this embodiment, the belt drive structure 706 can also be replaced by a sprocket, chain drive, or gear drive structure.

[0060] like Figure 7-8 As shown, the opposing limit assembly 5 includes a support platform 501 fixedly installed inside the roller frame 1. C-port sliding arms 502 are slidably installed at the left and right positions of the bottom end of the support platform 501. A bidirectional screw manual adjustment module 503 is installed at the bottom end of the support platform 501. The bidirectional screw manual adjustment module 503 is used to drive the two C-port sliding arms 502 to move towards each other or away from each other.

[0061] The top of the C-shaped sliding arm 502 extends to the top of the roller frame 1 and is fixed with a roller carrier 504. A vertical side roller 505 is rotatably mounted on the outer wall of the roller carrier 504 near the partition plate 2 via a bearing seat.

[0062] With this design, when using the opposing limiting assembly 5 and the vertical side roller 4 to assist in limiting the workpiece, the operator operates the bidirectional screw manual adjustment module 503. The bidirectional screw manual adjustment module 503 drives the two C-shaped sliding arms 502 in the width direction of the roller frame 1 to move closer to each other. At this time, the roller platform 504 and the vertical side roller 505 move towards the partition plate 2 and the vertical side roller 4 until both the vertical side roller 505 and the vertical side roller 4 are in contact with the length edge of the workpiece, thereby positioning and limiting the workpiece in the width direction and ensuring that the workpiece maintains a stable lateral position during the conveying and measurement process.

[0063] In this embodiment, both vertical side roller 2505 and vertical side roller 14 are made of stainless steel.

[0064] In this embodiment, the bidirectional lead screw manual adjustment module 503 is prior art, and its specific structure includes a lead screw, which is rotatably mounted on the support platform 501 via a bearing seat. The lead screw has two threaded sections, and threaded blocks are threadedly connected to each of the two threaded sections. The two threaded blocks are fixedly connected to the corresponding two C-port sliding arms 502. A handwheel is fixedly connected to one end of the lead screw, and the rotation of the handwheel drives the lead screw to rotate.

[0065] like Figure 1-8 As shown, the present invention also provides a processing and testing method for steel used in power transmission towers, based on the aforementioned processing and testing equipment for steel used in power transmission towers, comprising the following steps:

[0066] S101: Place two long U-shaped flat steel workpieces to be inspected stably above multiple rollers 3. According to the specific specifications of the U-shaped flat steel, start the opposing limit assembly 5 to limit and clamp the workpieces in the width direction. The control panel 10 starts the dual-axis linear drive assembly 6. The dual-axis drive assembly 6 adjusts the position of the dual-station roller synchronous feeding assembly 7 so that the position of the dual-station roller synchronous feeding assembly 7 matches the position of the workpiece to be transferred.

[0067] In step S101, the working principle of the opposing limit assembly 5 is as follows: the operator operates the bidirectional screw manual adjustment module 503 to drive the two C-port sliding arms 502 to move towards each other. At this time, the roller table 504 and the second vertical side roller 505 move towards the partition plate 2 and the first vertical side roller 4 until the second vertical side roller 505 and the first vertical side roller 4 are in contact with the length edge of the workpiece, thereby positioning and limiting the workpiece in the width direction, ensuring that the workpiece maintains a stable lateral position during the conveying and measurement process.

[0068] In step S101, the working principle of the dual-axis linear drive assembly 6 is as follows: the bidirectional lead screw electric linear module 602 is turned on by the control panel 10. The bidirectional lead screw electric linear module 602 drives the left slide 603 and the right slide 604 to move towards each other. At this time, the left slide 603 and the right slide 604 drive the two slides 605 to move to adjust the position of the dual-station roller synchronous feeding assembly 7 for easy use.

[0069] S102: Install the digital micrometer 9 at the fixed position at the top of the partition plate 2 through the adjustment bracket 8, so that the probe of the digital micrometer 9 is perpendicular to and slightly in contact with the detection point of the U-shaped flat steel surface to be measured, and then zero the digital micrometer 9, which serves as the reference point for the entire measurement process.

[0070] S103: Start the dual-station roller synchronous feeding assembly 7 via the control panel 10, drive two U-shaped flat steel workpieces to pass smoothly and at a constant speed along their length through the measurement area of ​​the digital micrometer 9, with its probe continuously in contact with the workpiece surface, and monitor and record the microscopic height change of the workpiece surface relative to the initial zero point in real time as the workpiece moves.

[0071] In step S103, the working principle of the dual-station roller synchronous feeding assembly 7 is as follows: the keyway shaft 701 and the spline shaft 702 can extend and retract according to the moving distance of the bidirectional ball screw electric linear module 602. At this time, the keyway shaft 701 and the spline shaft 702 maintain power connection. The servo motor 704 starts to drive the keyway shaft 701 and the spline shaft 702 to rotate. The keyway shaft 701 and the spline shaft 702 drive the plate rubber wheel 705 on their respective sides to rotate through the belt drive structure 706. The plate rubber wheel 705 drives the workpiece to move along the length direction until it passes through the detection area where the digital display dial indicator 9 is located.

[0072] In step S103, during the entire movement process, the workpiece is constrained by the opposing limit assembly 5, the idler roller 3 and the vertical side roller 4, maintaining a stable posture and preventing abnormal jumping or shaking. At this time, the digital display dial indicator 9, which is always in a fixed position, continuously contacts the workpiece surface with its probe. As the workpiece moves, it monitors and records the microscopic height change of the workpiece surface relative to the initial zero point in real time.

[0073] S104: After the entire U-shaped flat steel workpiece has completely passed the measuring point of the digital micrometer 9, close the dual-station roller synchronous feeding assembly 7, and then analyze the measured value on the digital micrometer 9 to determine whether the surface flatness of the workpiece meets the requirements.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
