Description

Technical Field

[0001] This invention relates to the field of lifting fixture technology, specifically a lifting fixture for a turbocharger. Background Technology

[0002] A turbocharger is an air compressor driven by the inertial force of exhaust gas from an engine. By compressing air, it increases the intake air volume of the engine, thereby increasing output power and torque. Turbochargers are in huge demand in fields such as ocean-going vessels, large commercial vehicles, construction machinery, and the automotive aftermarket. Their global distribution is usually carried out by container shipping, and they are transported to various places after being loaded and unloaded at ports.

[0003] In current port lifting and transshipment operations, turbochargers are mostly packed and transported in a horizontal position. However, this horizontal transport method has significant drawbacks: First, the turbocharger's turbine shaft rotor system is extremely sensitive to vibration. The continuous vibration from container transport while horizontal can easily induce crack propagation in rotor components, bearing wear, and even fatigue fracture, seriously threatening the product's transport reliability. Second, turbochargers are usually installed and used vertically, and there is an angular deviation between the horizontal position and the position required for lifting operations. If the turbocharger is initially horizontal, it needs to be manually flipped and adjusted to a vertical position before lifting, which increases the labor intensity, prolongs the lifting operation time, and reduces the overall lifting efficiency.

[0004] Therefore, how to directly hoist turbochargers vertically, quickly adjust them to a vertical position and achieve stable clamping after they are removed from a horizontal position, thereby reducing manual intervention, improving hoisting efficiency and reducing the risk of vibration damage, has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a lifting fixture for turbochargers, in order to solve the technical problem in the prior art that if the initial placement posture of the turbocharger is inconsistent, the placement posture of the turbocharger needs to be manually adjusted before it can be lifted by the above-mentioned lifting device, which increases the labor intensity and reduces the lifting efficiency of the turbocharger.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lifting clamp for a turbocharger, comprising:

[0007] A horizontally arranged base plate has a support portion at one end for insertion into the turbocharger intake port; Two clamping members are vertically arranged on both sides of the substrate. The clamping members can slide in the vertical direction and swing left and right relative to the substrate to clamp the turbocharger suspended on the support. A carrier is disposed on the top of the substrate and located between two clamping members. The carrier is connected to the substrate via a releasable connector. When the carrier and the substrate are separated from each other by the releasable connector, the carrier acts on the top of the clamping member, causing the tops of the two clamping members to tilt in a direction away from each other.

[0008] According to the above technical solution, the turbocharger's air intake is supported by a support part. Then, when the base plate and the carrier are connected, the turbocharger is lifted off the ground by a certain distance using the support part to adjust the turbocharger's posture. Subsequently, the base plate and the carrier are separated by a releasable connector. The carrier can then drive the clamping member to clamp the turbocharger lifted off the ground by the support part, ensuring the stability of the turbocharger during the hoisting process. At the same time, the turbocharger can be hoisted in various postures without the need for manual adjustment of the turbocharger's orientation.

[0009] Preferably, the top of the substrate has a recessed portion, and the bottom of the support member has a protrusion that matches the recessed portion. The protrusion is provided with at least one set of opposing first sliding grooves in the circumferential direction, and the inner wall of the recess is provided with a second sliding groove extending radially along the first sliding groove. A release member is slidably provided inside the first sliding groove, and the release member is connected to a telescopic drive member that drives it to slide inside the first sliding groove. When the substrate and the carrier are in a connected state, the protrusion is inserted into the recess, and the release member slides inside the first slide groove through the telescopic drive member and partially extends into the second slide groove. When the release member is fully retracted into the first groove by the telescopic drive member, the substrate and the carrier member detach from each other.

[0010] According to the above technical solution, when the release component is partially inserted into the second slide groove, the connection between the protrusion and the recess is realized, that is, the connection between the base plate and the carrier is completed. Then, the release component is slidable inside the first slide groove by the telescopic drive component, thus completing the release and connection between the base plate and the carrier. This ensures the automation level of the entire hoisting process and reduces the input of labor costs.

[0011] Preferably, the telescopic drive component is one of a cylinder, a hydraulic cylinder, and an electric lead screw; The free end of the telescopic drive component is directly or indirectly connected to the release component via a connector.

[0012] Preferably, the first groove is opened toward the clamping member, and the second groove extends radially to the position of the clamping member; A trigger rod is slidably provided inside the second groove, and a first wedge-shaped surface facing obliquely upward is provided at the end of the trigger rod near the clamping member; Vertical guide grooves are provided on opposite sides of the two clamping members. When the release member extends into the second sliding groove, the end of the trigger rod near the clamping member extends into the guide groove. As the clamping member slides vertically, the guide groove slides outside the trigger rod. A second wedge-shaped surface facing downwards is provided at the top of the guide groove.

[0013] According to the above technical solution, the design of the second slide and the trigger rod makes the clamping part more stable during the up and down sliding process, and there will be no deviation in direction and angle. At the same time, it can also provide data source for the control of the subsequent telescopic drive component, ensuring that the separation of the substrate and the carrier component is only performed when the clamping part is at the bottom, thus avoiding the occurrence of accidents.

[0014] Preferably, a pressure sensor is installed at one end of the trigger rod near the release member. The pressure sensor transmits the collected data to the control module, which analyzes the data and sends control commands to the telescopic drive member.

[0015] According to the above technical solution, a pressure sensor is set between the trigger rod and the release member as the basis for triggering the telescopic drive member. When the clamping member slides down into place, it will squeeze the trigger rod under the action of the first wedge surface and the second wedge surface. At this time, the detection data of the pressure sensor increases, which means that the clamping member can be used to clamp the turbocharger. When the data conditions are met, the telescopic drive member is controlled to retract through the control module to complete the release of the base plate and the carrier member, thus realizing the clamping member clamping the turbocharger that is lifted off the ground.

[0016] Preferably, a ball bearing for reducing friction with the second wedge surface is embedded in the first wedge surface.

[0017] According to the above technical solution, the ball bearing design can reduce the friction between the first wedge surface and the second wedge surface, allowing the force exerted by the clamping member on the trigger rod to be transmitted more comprehensively to the pressure sensor, ensuring the timely response of the telescopic drive component. At the same time, in order to reduce the friction between the release component and the trigger rod and the first and second slides, oil injection holes can be opened on the base plate and the carrier component. Lubricating oil can be periodically injected between the trigger rod and the second slide and between the release component and the first and second slides through the oil injection holes to ensure the smooth sliding of the release component and the trigger rod and avoid jamming.

[0018] Preferably, the clamping member slides vertically through guide grooves formed on both sides of the substrate; The guide groove has a first fault-tolerant surface facing upward on one side wall away from the carrier, and a second fault-tolerant surface facing downward on the other side wall.

[0019] According to the above technical solution, the first fault-tolerant surface and the second fault-tolerant surface can ensure that when the clamping component slides up and down inside the guide groove, the bottom of the clamping component can tilt towards the turbocharger, thereby realizing the clamping of the turbocharger by the clamping component during the hoisting process.

[0020] Preferably, both ends of the carrier are provided with support plates located on the substrate, the top of the support plate is provided with a horizontal plate facing the carrier, and the side of the horizontal plate away from the support plate is provided with a downwardly extending limiting plate. Both ends of the carrier are provided with limiting grooves that match the limiting plates. When the carrier and the substrate are separated from each other, the limiting plates slide inside the limiting grooves.

[0021] According to the above technical solution, the sliding position of the carrier can be restricted, avoiding the carrier from detaching from the two clamping parts during the separation process from the substrate, which could lead to a safety accident and ensure the stability and safety of the turbocharger hoisting process.

[0022] Preferably, an elastic buffer is provided between the cross plate and the upper surface of the bearing member.

[0023] According to the above technical solution, the elastic buffer can effectively reduce the abrupt change during the separation of the substrate and the carrier, ensuring the stability of the entire hoisting device during the clamping of the turbocharger by the clamping component. At the same time, it can prevent the turbocharger from being damaged due to excessive clamping force of the clamping component.

[0024] Preferably, the top of the clamping member is provided with a first inclined surface facing the carrier and downward, and the carrier is provided with second inclined surfaces on both sides near the clamping member; When the substrate and the carrier separate, the second inclined surface comes into contact with the first inclined surface and drives the tops of the two clamping members to tilt in a direction away from each other.

[0025] According to the above technical solution, the design of the first and second inclined surfaces can avoid excessive pressure and wear caused by the small force-bearing area when the carrier and the clamping parts are in contact, and can effectively extend the service life of the carrier and the clamping parts.

[0026] Compared with the prior art, the beneficial effects of the present invention are: 1. The turbocharger's air intake is supported by the support part. Then, when the base plate and the carrier are connected, the turbocharger is lifted off the ground by a certain distance using the support part. The attitude of the turbocharger is adjusted. Then, the base plate and the carrier are separated by the releasable connector. The carrier can then drive the clamping part to clamp the turbocharger lifted off the ground by the support part, ensuring the stability of the turbocharger during the hoisting process. At the same time, the turbocharger can be hoisted in various attitudes without the need for manual adjustment of the turbocharger's position.

[0027] 2. The present invention uses a release member as a bridge connecting the substrate and the carrier. When the release member is partially inserted into the second slide groove, the connection between the protrusion and the recess is realized, that is, the connection between the substrate and the carrier is completed. Then, the release member is slidable in the first slide groove by the telescopic drive member, thus completing the release and connection between the substrate and the carrier. This ensures the automation of the entire hoisting process and reduces the input of labor costs.

[0028] 3. This invention, through the limiting plate and limiting groove, can restrict the sliding position of the carrier, preventing the carrier from detaching from the two clamping members during the separation process from the base plate, thus avoiding safety accidents. This ensures the stability and safety of the turbocharger during hoisting. At the same time, the use of elastic buffer can effectively reduce the abrupt change during the separation process of the base plate from the carrier, ensuring the stability of the entire hoisting device during the clamping process of the turbocharger. In addition, it can prevent the clamping force of the clamping members on the turbocharger from being too large, which could damage the turbocharger. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example: A lifting clamp for a turbocharger is disclosed, such as... Figure 1 As shown, the system includes a horizontally arranged base plate 100. One end of the base plate 100 has a support portion 200 for inserting into the turbocharger intake port. The support portion 200 is L-shaped and faces the other end of the base plate 100. In this embodiment, as shown... Figure 9 As shown, a flange 201 can also be provided on the support part 200. Specifically, the flange 201 and the support part 200 are rotatably connected in the circumferential direction, that is, the flange 201 can rotate with the attitude adjustment of the turbocharger. When the support part 200 is inserted into the air inlet of the turbocharger, it is connected to the flange of the air inlet of the turbocharger by bolts, which ensures the stability of the support part 200 for the lifting of the turbocharger.

[0033] Furthermore, such as 2 and Figure 7 As shown, guide grooves 105 are provided through both sides of the substrate 100. A first fault-tolerant surface 106 facing upward is provided on the side wall of the guide groove 105 away from the support member 400, and a second fault-tolerant surface 107 facing downward is provided on the other side wall of the guide groove 105. A clamping member 300 is provided inside the guide groove 105 and can slide up and down.

[0034] It should be noted that by setting the first fault-tolerant surface 106 and the second fault-tolerant surface 107, the clamping member 300 can slide inside the guide groove 105 while the bottom of the clamping member 300 can swing in opposite directions, thereby achieving clamping of the turbocharger during the hoisting process and ensuring the stability of the turbocharger during hoisting. In order to prevent the bottom of the clamping member 300 from swinging in the opposite direction, the first fault-tolerant surface 106 must be set at an angle upward on the side wall of the guide groove 105 away from the bearing member 400, and the second fault-tolerant surface 107 must be set at an angle downward on the other side wall of the guide groove 105.

[0035] In this embodiment, as Figure 2 As shown, a support member 400 is provided on the upper surface of the substrate 100, and the upper surface of the support member 400 is connected to a gantry crane or other hoisting equipment by wire rope or other hoisting rope.

[0036] Specifically, such as Figure 3 and Figure 5 As shown, a recessed portion 101 is provided on the top of the substrate 100, and a protrusion 401 matching the recessed portion 101 is provided on the bottom of the support member 400. When the substrate 100 and the support member 400 are attached to each other, the protrusion 401 is inserted into the recessed portion 101.

[0037] Furthermore, such as Figure 6 and Figure 7 As shown, the protrusion 401 has at least one set of opposing first grooves 402 circumferentially arranged, and the inner wall of the recess 101 has a second groove 403 extending radially along the first grooves 402. The first grooves 402 are opened toward the clamping member 300, and the second grooves 403 extend radially to the position of the clamping member 300 and pass through the recess 101 and the guide groove 105. A release member 404 is slidably arranged inside the first groove 402, and a trigger rod 102 is slidably arranged inside the second groove 403. The release member 404 is driven to slide inside the first groove 402 and the second groove 403 by a telescopic drive member 405. For example, the telescopic drive member 405 is installed on the top of the support member 400, and the telescopic drive member 405 and the release member 404 are connected by a connector 406.

[0038] In this embodiment, the design of the first slide groove 402, the second slide groove 403, and the release member 404 enables the longitudinal displacement between the substrate 100 and the support member 400 to be fixed, ensuring that the substrate 100 and the support member 400 are connected before the clamping member 300 clamps the turbocharger suspended on the support portion 200.

[0039] Specifically, when the substrate 100 and the support member 400 are in a connected state, the protrusion 401 is inserted into the recess 101, and the release member 404 slides inside the first slide groove 402 via the telescopic drive member 405 and partially extends into the second slide groove 403, thus completing the fixation between the substrate 100 and the support member 400; when the release member 404 is fully retracted into the first slide groove 402 via the telescopic drive member 405, the release member 404 no longer fixes the relative position between the protrusion 401 and the recess 101, that is, the substrate 100 and the support member 400 are fixed. The carrier members 400 are detached from each other. In this embodiment, because the top of the clamping member 300 is provided with a first inclined surface 303 facing the carrier member 400 and inclined downward, and the carrier member 400 is provided with second inclined surfaces 408 on both sides near the clamping member 300, when the substrate 100 and the carrier member 400 are detached from each other, the carrier member 400 moves upward relative to the substrate 100, driving the top of the clamping member 300 to move in the opposite direction, that is, the bottom of the clamping member 300 swings towards each other, thus completing the clamping of the turbocharger suspended on the support 200.

[0040] In this embodiment, as Figure 6 As shown, a tilted portion 304 facing the turbocharger is provided at the bottom of the clamping member 300. An anti-slip groove 305 is provided on the side of the tilted portion 304 near the turbocharger, so that the clamping member 300 can support the turbocharger during the process of clamping the turbocharger from both sides, ensuring the stability of the turbocharger during the hoisting process. For example, a baffle (not shown in the figure) can also be provided on the side of the bottom of the clamping member 300 away from the support portion 200 to prevent the turbocharger from slipping off the side of the clamping member 300 away from the support portion 200 and causing a safety accident.

[0041] In this embodiment, as Figure 2 and Figure 4As shown, support plates 501 are provided at both ends of the carrier 400 at positions on the surface of the substrate 100. A horizontal plate 502 facing the carrier 400 is provided on the top of the support plate 501. A downwardly extending limiting plate 503 is provided on the side of the horizontal plate 502 away from the support plate 501. Limiting grooves 407 matching the limiting plates 503 are provided at both ends of the carrier 400. When the carrier 400 is separated from the substrate 100, the limiting plate 503 slides inside the limiting groove 407. Through the design of the limiting plate 503 and the limiting groove 407, when the carrier 400 is separated from the substrate 100, the carrier 400 can slide along the direction of the limiting plate 503, avoiding deviation in the movement direction of the carrier 400, which could lead to failure to act on the clamping member 300 or uneven force, resulting in safety hazards in the lifting device.

[0042] Furthermore, an elastic buffer 504 is provided between the horizontal plate 502 and the upper surface of the carrier 400. For example, the elastic buffer 504 can be a spring or other components with elasticity and buffering function. The elastic buffer 504 can effectively reduce the abruptness during the separation of the base plate 100 from the carrier 400, ensuring the stability of the entire hoisting device during the clamping of the turbocharger by the clamping member 300. At the same time, it can prevent the clamping force of the clamping member 300 on the turbocharger from being too large, which would damage the turbocharger.

[0043] It should be noted that, as Figure 6 and Figure 8 As shown, vertical guide grooves 301 are provided on opposite sides of the two clamping members 300. When the release member 404 partially extends into the second sliding groove 403, the end of the trigger rod 102 near the clamping member 300 extends into the guide groove 301. As the clamping member 300 slides vertically, the guide groove 301 slides outside the trigger rod 102. A second wedge-shaped surface 302 facing downwards is provided at the top of the guide groove 301. A pressure sensor is installed at the end of the trigger rod 102 near the release member 404. The pressure sensor's data is transmitted to the control module. The control module analyzes the pressure sensor's data and sends control commands to the telescopic drive member 405.

[0044] In this embodiment, the trigger rod 102 is designed to enable the telescopic drive 405 to automatically drive the release member 404 without manual operation, achieving a higher degree of automation. This automatic release mechanism is also designed for convenient remote control; operators can receive commands from the control module via wireless signals from a distance, triggering the telescopic drive 405 without needing to approach the turbocharger during hoisting, thus improving operational safety and convenience. Therefore, during hoisting, the bottom of the clamping member 300 will clamp the turbocharger from the bottom. This process requires the clamping member 300 to be in its lowest position within the guide groove 105 to ensure stable clamping of the turbocharger. When the clamping member 300 is in its lowest position, the guide groove 301 will slide to the second wedge outside the trigger rod 102. At position 302, the first wedge-shaped surface 103 of the trigger rod 102 is in contact with the second wedge-shaped surface 302 of the guide groove 301. At this time, the pressure data collected by the pressure sensor between the trigger rod 102 and the release member 404 will increase, and the clamping member 300 will be basically in the lowest position. The pressure sensor transmits the collected pressure data to the control module. The control module analyzes the data and finds that the pressure data decreases, remains constant, and then increases again within a certain time range. It then sends a control command to the telescopic drive member 405. The telescopic drive member 405 drives the release member 404 to retract into the first slide groove 402. At this time, the separation between the base plate 100 and the support member 400 is completed. The second inclined surface 408 of the support member 400 acts on the first inclined surface 303 of the clamping member 300, so that the clamping member 300 can be used to clamp the turbocharger suspended on the support part 200.

[0045] For example, regarding the analysis of pressure data detected by the pressure sensor by the control module, the distance is as follows: like Figure 11 As shown, at time t1, the pressure data detected by the pressure sensor is p1, as follows: Figure 12As shown, at time t2, the support 200 completes the suspension of the turbocharger. However, at this time, the turbocharger has not yet left the ground, and the bottom of the clamping member 300 is still in contact with the ground and has not slid down to the lowest position relative to the base plate 100. The pressure data detected by the pressure sensor is p2. At time t3, when the entire hoisting device leaves the ground, the pressure data detected by the pressure sensor is p3. When the difference between time t1 and time t3 is less than the set time difference threshold t, and the pressure data difference between pressure data p1 and pressure data p2 is less than the set pressure data difference threshold p, and pressure data p2 is less than both pressure data p1 and pressure data p3, it can be determined that at this time, the release member 404 needs to be completely retracted into the first slide groove 402 by the telescopic drive member 405 to complete the separation between the base plate 100 and the support member 400, and to complete the operation of the clamping member 300 clamping the turbocharger from the bottom to both sides of the turbocharger. Figure 13 As shown.

[0046] Furthermore, such as Figure 10 As shown, in order to allow more of the weight of the clamping member 300 to be transmitted to the pressure sensor through the trigger rod 102, a plurality of balls 104 are embedded in the first wedge-shaped surface 103 of the trigger rod 102 to reduce the friction between the first wedge-shaped surface 103 and the second wedge-shaped surface 302. In this embodiment, in order to reduce the friction between the release member 404 and the first slide groove 402 and the second slide groove 403, as well as the friction between the trigger rod 102 and the second slide groove 403, oil injection holes can be opened on the substrate 100 and the carrier member 400. Lubricating oil is injected into the first slide groove 402 and the second slide groove 403 through the oil injection holes to reduce the friction between the release member 404 and the first slide groove 402 and the second slide groove 403, as well as the friction between the trigger rod 102 and the second slide groove 403, so that the release member 404 and the trigger rod 102 can slide more smoothly.

[0047] In this embodiment, during the hoisting process of the turbocharger, such as Figures 11-13As shown, during hoisting, the entire stress point is on the carrier 400, and the carrier 400 applies the force to the top of the clamping member 300, driving the bottom of the clamping member 300 to clamp the turbocharger from the bottom to both sides. During this process, the telescopic drive member 405 separates the base plate 100 from the carrier 400. After the turbocharger is hoisted and unloaded, the bottom of the clamping member 300 contacts the ground first. As the entire hoisting device moves further down, the force exerted by the carrier 400 on the top of the clamping member 300 decreases. When the carrier 400 no longer bears the upward tension of the wire rope, the turbocharger also completes the process of touching the ground. When the turbocharger touches the ground, it drives the bottom of the clamping member 300 to separate to both sides. At this time, it is possible to embed ball bearings or other materials that can reduce the stress on the bottom of the clamping member 300. The components with low friction allow for smoother separation of the clamping member 300 from the bottom to both sides. After the turbocharger detaches from the support 200, the protrusion 401 on the support member 400 will re-insert into the recess 101 under the action of gravity. At this time, the telescopic drive member 405 can be manually controlled to drive the release member 404 to slide into the second slide groove 403, thus fixing the position of the substrate 100 and the support member 400. Alternatively, a pressure sensor can be installed on the contact surface between the recess 101 and the protrusion 401. When a sudden increase in pressure is detected, it means that the protrusion 401 has inserted into the recess 101. At this time, the control module sends a control command to the telescopic drive member 405 to control the telescopic drive member 405 to drive the release member 404 to slide into the second slide groove 403, thus fixing the position of the substrate 100 and the support member 400.

[0048] Finally, it should be noted that, because in this embodiment, during the turbocharger hoisting process, the turbocharger is partially hoisted—that is, the turbocharger is off the ground support, but the clamping member 300 is not clamping the turbocharger—the hoisting device of this embodiment can adapt to the hoisting of turbochargers with different placement postures. Specifically, for example... Figures 14-16 As shown.

[0049] In another embodiment, after the turbocharger is transported by water, it needs to be hoisted and transferred at the port. To save space during water transport, the turbocharger's placement may not be uniform. During the hoisting and transfer process at the port, the turbocharger is initially placed horizontally (e.g., on the bottom of a container). Figure 15 As shown, when hoisting a turbocharger that is lying flat, the following steps should be performed: First, the entire hoisting clamp is slowly lowered to the turbocharger position under the action of the wire rope. When the clamping part 300 touches the ground, it will remain stationary under the support of the ground. At this time, the base plate 100 continues to descend until the support part 200 is at the same level as the turbocharger in the flat position. Secondly, by controlling the lateral movement of the entire lifting fixture, the support part 200 is inserted into the air inlet of the turbocharger, and the flange 201 is connected to the air inlet by bolts to complete the initial fastening of the turbocharger. Then, by controlling the lifting clamps, the turbocharger will change from its initial horizontal position to a vertical position as the lifting clamps continue to rise. Figure 12 As shown, however, the turbocharger is still not off the ground, nor is the clamping component 300. As the lifting clamp continues to be lifted, the entire assembly will transform into the shape shown below. Figure 17 In the state shown, the clamping member 300 is not clamping the turbocharger. With further hoisting, the release member 404 can be remotely controlled to retract, thus ceasing to abut the trigger lever 102. At this point, the carrier member 400 also separates from the base plate 100. After separation, the carrier member 400 moves upward relative to the base plate 100, abutting against the upper half of the clamping member 300 on the base plate. This expands the upper half of the two clamping members 300 on the base plate, causing the lower half of the two clamping members 300 to move closer together and clamp the turbocharger. Figure 13 As shown; thus, port hoisting can be realized. Through the above process, in the high-intensity operation of the port, no manual on-site intervention is required. With the cooperation of remote control, the multi-position remote hoisting of turbochargers can be realized.

[0050] In the high-paced operations of ports, this device can be used in conjunction with a remote control system, allowing operators to complete the entire process from attitude adjustment to clamping wirelessly from a safe distance. This effectively avoids the safety risks caused by personnel approaching heavy objects in the port hoisting area, and also solves the efficiency bottleneck caused by manual turning when multiple turbochargers are hoisted continuously.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
