Description

Technical Field

[0001] The invention relates to the field of pipeline prefabrication, and in particular to a standardized device used for pipeline prefabrication. Background Art

[0002] In the process of prefabrication of industrial pipelines, especially in the petroleum and petrochemical pipeline industry, there are many kinds of pipe fittings, such as flanges, elbows, reducers, tees, etc. These pipe fittings have different shapes, such as circular, curved, conical, and T-shaped; the diameters of pipe fittings are also different, such as DN50, 80, 100, 150, 200, 250, 300, etc., and the wall thickness of pipe fittings is also diversified, such as SCH20, SCH30, SCH40, SCH60, SCH80, SCH100, etc. The differences in shape and size of these pipe fittings have led to a large proportion of manual work in the process of lifting, transportation, grinding, storage, assembly, welding, etc., and the degree of mechanization, automation, and intelligence is very low.

[0003] As labor costs increase, skilled workers are becoming fewer and fewer, and the demand for automation and intelligence in pipeline prefabrication is becoming more and more urgent.

[0004] In the prior art, in order to improve work efficiency and ensure work quality as much as possible, various tools are used to adapt to one or two of the above-mentioned pipe fittings. However, none of these tools can be applied to all pipe fittings, and even if these tools are applied to a certain pipe fitting, they are only for manual operations (such as manual assembly) or semi-automatic operations (such as semi-automatic welding) in the subsequent process, and cannot meet the needs of automated and intelligent operations in the subsequent process.

[0005] In order to adapt to the automated and intelligent lifting, transportation, grinding, storage, assembly, welding and other pipeline prefabrication operations, the means used in the prior art are as follows: the machine used to automatically and intelligently complete the lifting, transportation, grinding, storage, assembly, welding and other processes is designed to be directly applicable to various pipe fittings. However, it has been proved that this technical means is not feasible. So far, there is no such machine on the market that can fully realize automated and intelligent operations and can be directly applied to various pipe fittings. Even if such a machine can be designed, its structure will be extremely complicated, and it has the disadvantages of high manufacturing cost and limited scope of application.

[0006] Therefore, technicians in this field are committed to developing a standardized device for pipeline prefabrication operations, first loading various pipes into the standardized device to form one or several unified pipe fitting modules, and then designing automated and intelligent machines for lifting, transportation, grinding, storage, assembly, welding, etc. to only be suitable for this unified pipe fitting module, thereby simplifying the structure of these machines and reducing the manufacturing cost of such machines.

[0017] In some embodiments, optionally, the pipe positioning component includes two second positioning clamps arranged opposite to each other, each of the two second positioning clamps corresponds to a clamping mechanism, and the clamping mechanism is configured to be able to apply a clamping force on the corresponding second positioning clamp, so that the two second positioning clamps can clamp the pipe to be processed.

[0018] In some embodiments, optionally, a force transmission square plate and a force transmission square frame are provided between the second positioning clamp plate and the corresponding clamping mechanism, the force transmission square plate is in contact with the clamping mechanism, and the force transmission square frame is located between the second positioning clamp plate and the force transmission square plate.

When designing an automated and intelligent machine using the pipe fitting module formed by the standardized device, there is no need to consider pipe fittings of different shapes and sizes, only the standardized device and the standardized pipe fitting module formed by it need to be considered, so that the structure of the machine can be designed to be simple, which can greatly reduce the manufacturing cost of the machine.

DETAILED DESCRIPTION

[0038] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0039] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention in a schematic manner, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0040] While some exemplary embodiments of the present invention have been described for the purpose of illustration, it should be understood that the present invention may be implemented in other ways not specifically shown in the drawings.

[0041] The present invention provides a standardized device 100 for pipeline prefabrication, which is used to install pipe fittings 200 to be processed, including but not limited to flanges, elbows, reducers, and tees. When in use, the pipe fittings 200 to be processed are installed in the standardized device 100 to form a pipe fitting module with uniform specifications, and then the pipe fitting module is subjected to corresponding prefabrication processing procedures using automated and intelligent machines for hoisting, transportation, grinding, storage, assembly, welding and other processes. This allows these machines to only consider the application of such a unified pipe fitting module when designing, without considering various pipe fittings of different shapes, sizes, and wall thicknesses. Therefore, these machines are easier to realize automation and intelligence, and can simplify the structure of these machines and reduce the manufacturing cost of these machines.

[0042] like Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, the standardized device 100 for pipe fitting operation provided by the present invention comprises a frame 10, a pipe fitting fixing component and a pipe fitting positioning component. The various surfaces of the frame 10 enclose a receiving space 101 for receiving the pipe fitting 200 to be processed. The pipe fitting fixing component is arranged in the receiving space 101 and is detachably connected to the frame 10 through an L-shaped positioning part. The pipe fitting fixing component is used to fix the pipe fitting 200 to be processed in the receiving space 101. The pipe positioning component is detachably connected to the pipe fixing component or the frame 10, and can be positioned at a suitable position in the frame 10 or on the pipe fixing component according to the size of the pipe 200 to be processed, and is used to adjust the position of the pipe 200 to be processed, such as adjusting the height of the pipe 200 to be processed or the relative position to the frame 10, so that when different standardized devices 100 are loaded with different pipes 200 to be processed, these pipes 200 to be processed have relatively uniform or matching postures, which is beneficial for subsequent grinding, assembly, welding and other processes. As long as the standardized device 100 is in the preset posture, there is no need to consider the positioning of the pipe 200 to be processed in these processes.

[0043] like Fig. 9 and Fig.10 As shown, the frame 10 has six faces, forming a cube or a cuboid.

[0044] The frame 10 has a first surface 102 for the entry and exit of pipes. Figure 5 and Figure 6As shown, the first surface 102 is hollow as a whole, that is, the entire surface is unobstructed, which is convenient for installing the pipe 200 to be processed. In some embodiments, the pipe loading device can be used to fix the pipe to be processed in a standard posture, and then the first surface 102 of the frame 10 is aligned with the pipe 200 to be processed, and then the frame 10 is moved to cover the pipe 200 to be processed, so that the pipe 200 to be processed is located at a suitable position in the frame 10. Then, the pipe fixing component and the pipe positioning component are used to fix the pipe 200 to be processed in a preset position. In some embodiments, at least a portion of the first surface 102 can be set to be hollow, that is, an opening is set on the first surface 102, and the area of ​​the opening is smaller than the area of ​​the first surface 102, and the pipe 200 to be processed enters and exits the standardization device 100 through the opening.

[0045] The frame 10 has a second surface 103 that serves as a reference surface for upper and lower positioning and transportation. The second surface 103 can be set to intersect the first surface 102 perpendicularly. When the standardized device 100 containing the pipe 200 to be processed is transported, the second surface 103 contacts the machine used for transportation and serves as a reference surface for transportation. At the same time, in order to facilitate the pipe 200 to be processed to have a uniform center height and facilitate subsequent processes such as grinding, assembly, and welding, the second surface 103 serves as a reference surface for upper and lower positioning, so that different pipe modules have a unified reference reference, that is, a uniform height. The second surface 103 can be set to be partially hollow or solid.

[0046] The frame 10 has a third surface 104 perpendicular to the first surface 102. Figure 5 and Figure 6 As shown, the third surface 104 is hollow as a whole, that is, the third surface 104 is unobstructed, so that the third surface 104 and the first surface 102 together form a passage for the pipe 200 to be processed to enter and exit the standardization device 100, further facilitating the pipe 200 to be processed to enter and exit the standardization device 100. The third surface 104 can also be set to be partially hollowed out as a supporting component to improve the rigidity of the entire frame 10, and at the same time set to be hollowed out to reduce weight. When the third surface 104 is set to be hollow as a whole, as shown in FIG. Figure 1As shown, at least two detachable cross bars can be provided on the third surface 104. One of the cross bars (i.e., the first cross bar 108) is provided at the connection between the first surface 102 and the third surface 104. Before the pipe 200 to be processed is clamped, the first cross bar 108 can be removed if necessary to facilitate the entry of the pipe 200 to be processed; after the pipe 200 to be processed enters, the first cross bar 108 is connected to ensure the rigidity of the frame 10. At least one of the cross bars (i.e., the second cross bar 109) is used to position the pipe fixing component to ensure the strength of the pipe fixing component, that is, after the pipe fixing component is installed in a suitable position in the frame 10 according to the size of the pipe 200 to be processed, the second cross bar 109 can be fixed near the pipe fixing component and close to the pipe fixing component, thereby ensuring the strength of the pipe fixing component and improving the rigidity of the frame. It should be understood that the number of the second cross bars 109 can be set to one or more according to actual needs.

[0047] For the frame 10, the fourth surface 105, the fifth surface 106 and the sixth surface 107 are used to play a supporting role and improve the rigidity of the entire frame 10. In addition, a plurality of through holes are provided on part or all of the fourth surface 105, the fifth surface 106 and the sixth surface 107 of the frame 10, such as Figure 1 As shown, these through holes may include a hoisting hole 110, and may also include a positioning hole 111 and a mounting hole 112, wherein the hoisting hole 110 facilitates the truss manipulator to hoist the standardized device 100, and the hoisting hole 110 can also reduce the weight of the frame 10; the positioning hole 111 is used for positioning during assembly, welding and other processes, and can be set as a tapered hole; the mounting hole 112 can be used to install the circular plate 72 of the crossbar or the top tightening mechanism, for example, a plurality of mounting holes 112 at different positions are set at a position adjacent to the third surface 104 on the frame 10, and then after the crossbar is set at a suitable position, the bolts are passed through these mounting holes 112 and screwed into the crossbar, thereby fixing the crossbar. These through holes enable each standardized device 100 to have a hoisting hole 110 and a positioning hole 111 of uniform specifications and positions, which is convenient for realizing automation and intelligence. In some embodiments, the fourth surface 105, the fifth surface 106 and the sixth surface 107, except for the through hole 110, are set to be solid. In some embodiments, the fourth surface 105, the fifth surface 106, and the sixth surface 107 are configured to be hollow, which can reduce the weight of the frame 10 and save the material for manufacturing the frame. It should be understood that the fourth surface 105, the fifth surface 106, and the sixth surface 107 can be partially configured to be hollow and partially configured to be solid; or all of the three surfaces can be configured to be hollow or solid; the specific configuration method can be selected according to actual needs.

[0048] The sixth surface 107 of the frame 10 can also be used as a front and rear positioning surface to achieve precise matching with machines for processes such as transportation, grinding, storage, assembly, and welding.

[0049] The pipe fixing component is detachably connected to the frame 10 and can be positioned at a suitable position in the frame 10 according to the size of the pipe 200 to be processed.

[0050] The pipe fixing component and the pipe positioning component are combined together to realize the positioning and fixing of the pipe 200 to be processed. The pipe fixing component and the pipe positioning component can be set at a suitable position in the frame 10 according to the size of the pipe 200 to be processed. On the one hand, the standardized device 100 can be applied to pipes 200 to be processed of different sizes and shapes, and on the other hand, it is conducive to the automation and intelligent processing of different pipes 200 to be processed. For example, when processing pipes of the same specification series, the shapes of the tees and elbows used are different. When traditional machines are used for lifting, transportation, grinding, storage, assembly, welding and other operations, if automation and intelligence are to be realized, the designed machine must be applicable to both tees and elbows, which will undoubtedly increase the complexity of the machine itself and increase the manufacturing cost of the machine. By using the standardization device 100 of the present invention, the standardization device 100 of the same specification can be used. Since the frame 10 is of the same specification, different pipe fittings 200 to be processed are installed in each standardization device 100 to form a plurality of pipe fitting modules with uniform lifting holes 110 and positioning holes 111. Through the pipe fitting fixing components and the pipe fitting positioning components, the ends of the pipe fittings 200 to be processed in each pipe fitting module extending out of the frame 10 have a uniform center height (relative to the second surface 103 of the frame 10, i.e., the reference surface), and the extending length is relatively fixed. Therefore, when designing automated and intelligent machines for processes such as lifting, transportation, grinding, storage, assembly, and welding, it is only necessary to consider the specifications of the standardized device 100 to be applicable to different pipe fittings 200 to be processed, which is very beneficial to realize automation and intelligence, simplify the machine structure, and reduce the machine manufacturing cost.

[0051] In some embodiments, Figure 1As shown, the pipe fixing component is a fixed baffle 20, and the fixed baffle 20 is connected to the frame 10 through an L-shaped positioning part 21. Specifically, the L-shaped positioning part 21 includes a vertical first part and a second part, the first part is connected to the surface of the frame 10, and the second part is connected to the fixed baffle 20. When the fixed baffle 20 is set to be connected to the third surface 104 of the frame 10, if the third surface 104 is hollow, the fixed baffle 20 is connected to the cross bar on the third surface 104 through the L-shaped positioning part 21. After determining the installation position of the pipe in the standardization device 100 according to the type and size of the pipe, the fixed baffle 20 is installed at the position through the L-shaped positioning part 21, and then the pipe 200 to be processed is fixed to the baffle 20 through the pipe positioning component.

[0052] In some embodiments, Figure 1 and Figure 3 As shown, there are two fixed baffles 20, which are arranged opposite to each other and parallel to each other, and the two fixed baffles 20 are respectively perpendicular to the first surface 102 of the frame 10. The pipe positioning component is a first positioning clamp 30 respectively arranged on the two fixed baffles 20, and the two first positioning clamps 30 are connected to the fixed baffles 20 through guide columns. Specifically, a plurality of holes for passing the guide columns are provided on the fixed baffle 20, and the guide columns are connected to the first positioning clamps 30 after passing through these holes. Two rows of set screws are provided on the fixed baffle 20, and the distance of the first positioning clamp 30 relative to the fixed baffle 20 can be adjusted by rotating the set screws. This structure is suitable for pipe fittings 200 to be processed such as elbows and tees. When in use, the two first positioning clamps 30 are nailed to the pipe fittings 200 to be processed by the set screws, so that the two first positioning clamps 30 clamp the pipe fittings 200 to be processed. In some embodiments, the pipe positioning component may also include other positioning parts, such as Figure 2 and Figure 4As shown, for example, a positioning V-shaped plate 50 and a positioning bolt 60 are provided to support and press the pipe 200 to be processed. The positioning V-shaped plate 50 can be provided on the second surface 103 of the frame 10, and the positioning screw 60 can be provided on the cross bars 108 and 109 of the third surface 104. The positioning V-shaped plate 50 and the positioning screw 60 can also be provided on other surfaces, and can be selected according to actual needs. In this embodiment, due to the influence of the weight of the pipe 200 to be processed, the friction between the first positioning clamping plate 30 and the pipe 200 to be processed is insufficient, which may cause the pipe 200 to be processed to shift downward under the action of gravity. At this time, the positioning V-shaped plate 50 and the positioning screw 60 can be used to support and clamp it. Under the action of the positioning clamping plate 30, the positioning V-shaped plate 50 and the positioning bolt 60, the pipe 200 to be processed can be shaped in posture, ensuring that the end of the pipe 200 to be processed extending out of the standardization device 100 has a uniform height relative to the reference surface, and the extended length is relatively fixed. In some embodiments, a layer of polyurethane may be covered on the first positioning clamp 30. When the first positioning clamp 30 clamps the pipe 200 to be processed, the polyurethane in contact with the pipe 200 to be processed is deformed due to its elasticity. The deformation matches the shape of the pipe 200 to be processed. Especially for pipes such as tees and elbows, which have an arc surface, the deformation of the polyurethane matches the arc surface, so that the first positioning clamp 30 forms an arc-like deformation to wrap the tees and elbows. When the weight of the tees and elbows themselves is not very heavy, the tees and elbows can be supported by the first positioning clamp 30 without the need to position the V-shaped plate 50 and the positioning screws 60. It should be noted that elbows and tees have different outer contours, such as Figure 1 As shown, the contact surface between the tee and the first positioning clamp 30 is the outer surface of a straight pipe. At this time, the first positioning clamp 30 can be set as a straight plate, which is clamped on the outer surface of the straight pipe to well position and clamp the tee; Figure 3 As shown, the elbow is curved, so when positioning the elbow, the first positioning clamp plate 30 can be set as an arc plate matching the elbow, so that the contact area between the first positioning clamp plate 30 and the elbow is larger, and the elbow can be clamped better. In some embodiments, in order to make the same fixed baffle plate 20 adapt to elbows of different sizes and reduce the conflict of holes, multiple groups of guide column holes and bolt holes for connecting and nailing with the first positioning clamp plate 30 are set at different positions on the fixed baffle plate 20.

[0053] In some embodiments, Figure 7 and Figure 8As shown, the number of fixed baffles 20 is one, and the fixed baffle 20 is parallel to the first surface 102 of the frame 10. The pipe positioning component is a positioning chuck 40 arranged on the fixed baffle 20. This structure is suitable for pipes 200 to be processed of flange, reducer and other types. When in use, the installation position of the pipe 200 to be processed in the standardized device 100 is determined according to the type and size of the pipe 200 to be processed, and then the fixed baffle 20 is fixed at this position, and then the pipe 200 to be processed is fixed in the positioning chuck 40. The positioning chuck 40 can be a three-jaw chuck. By reasonably setting the position of the positioning chuck 40, it can be ensured that the relative positions of different pipes 200 to be processed relative to the frame 10 when installed in the standardized device 100 are unified or matched, for example, the heights of different pipes 200 to be processed relative to the reference surface are unified. This setting facilitates the automation and intelligence of processes such as grinding, assembly, and welding. In some embodiments, the pipe positioning component may further include a positioning V-shaped plate 50 and a positioning screw 60 to support and press the pipe 200 to be processed. The positioning V-shaped plate 50 may be disposed on the second surface 103 (i.e., the reference surface) of the frame 10, and the positioning screw 60 may be disposed on the third surface 104. Alternatively, the positioning screw 60 may be disposed on other surfaces, depending on actual needs.

[0054] In some embodiments, Figure 5 and 6As shown, the pipe fixing component can be two opposite tightening mechanisms 70 arranged in the frame 10. The tightening mechanism 70 includes an annular plate 71 with internal threads and a circular plate 72 with external threads. The annular plate 71 is screwed on the outer circumference of the circular plate 72 by threads, so that the annular plate 71 can rotate around the circular plate 72. Under the action of the threads, the annular plate 71 can move along the axial direction of the circular plate 72. A lever 73 is arranged on the outer circumference of the annular plate 71. By pulling the lever 73, the annular plate 71 can be easily rotated. The circular plate 72 is fixed to the frame 10 by bolts. For example, a plurality of circular holes 113 are arranged on the fourth surface 105 of the frame 10. The bolts are passed through the circular holes 113 and then screwed into the circular plate 72, thereby fixing the circular plate 72. The number of circular holes 113 can be set according to actual needs. Here, it is set to six, and the six circular holes 113 are arranged in three rows, two in each row. The pipe fitting positioning component includes two second positioning clamps 74 arranged opposite to each other. The two second positioning clamps 74 are in contact with two tightening mechanisms 70 respectively. When the annular plate 71 is turned, the annular plate 71 moves inward along the axial direction of the circular plate 72, and the two second positioning clamps 74 are respectively tightened in the direction of the pipe fitting 200 to be processed. At this time, after the annular plate 71 rotates, a tightening force is generated, and the force is transmitted to the second positioning clamps 74, so that the pipe fitting to be processed is positioned in a preset posture. The area of ​​the second positioning clamp 74 can be approximately equal to the area of ​​the fourth surface 105 of the frame 10, and polyurethane is arranged on the second positioning clamp 74. Under the action of the tightening force, the polyurethane is deformed, so that there is a larger contact area between the two sides of the pipe fitting 200 to be processed and the second positioning clamp 74, so that the two second positioning clamps 74 can wrap the two sides of the pipe fitting 200 to be processed, providing a larger friction force and support force. At this time, even if the positioning V-shaped plate and the positioning screw are not provided, the two second positioning clamps 74 can well support the pipe fitting to be processed. The four corners of the second positioning clamp 74 can be set to be L-shaped, so that the second positioning clamp 74 cooperates with the cross bar of the frame 10 through the L-shaped corners. In addition, the second positioning clamp 74 itself has a certain thickness. Therefore, it is no longer necessary to set a connecting piece between the second positioning clamp 74 and the tightening mechanism 70. Instead, the second positioning clamp 74 is directly placed in the frame 10, and the second positioning clamp 74 will not tilt. In some embodiments, such as Figure 5 As shown, a force transmission square plate 75 and a force transmission square frame 76 may be provided between the second positioning clamping plate 74 and the pressing mechanism 70. Since the distance that the annular plate 71 moves along the circular plate 72 is limited, in order to make the structure adaptable to pipes of a larger size range, the force transmission square plate 75 and the force transmission square frame 76 are provided. Figure 5As shown, when the size of the pipe is small, even if the annular plate 71 is moved to the maximum distance, the second positioning clamp 74 cannot clamp the pipe. At this time, a force transmission square plate 75 and a force transmission square frame 76 are set between the second positioning clamp 74 and the tightening mechanism 70, which increases the distance between the second positioning clamp 74 and the tightening mechanism 70, so that the second positioning clamp 74 can clamp the pipe well. The force transmission square plate 75 is in contact with the annular plate 71. The force transmission square plate 75 is set in a square shape, so that when the annular plate 71 rotates, the force transmission square plate 75 will not rotate with the annular plate 71, thereby ensuring the stability of the device. The force transmission square frame 76 is located between the force transmission square plate 75 and the second positioning clamp 74, and can be made of aluminum alloy with a smaller specific gravity. According to the size of the pipe, a plurality of parallel force transmission square frames 76 can be set. As shown Figure 6 As shown, when the size of the pipe is relatively large, the force transmission square plate 75 and the force transmission square frame 76 may not be used, but the pressing mechanism 70 may directly apply the pressing force on the second positioning clamping plate 74 .

[0055] The tightening structure 76 can be applied to pipe fittings such as elbows and tees. At this time, since the area of ​​the second positioning clamp 74 is very large, there is no need to set positioning clamps of different shapes considering the shapes of the elbows and tees. Only the second positioning clamp 74 as shown in the figure needs to be used. It is applicable to elbows and tees of different sizes and shapes without replacing the positioning clamp, and the versatility is better.

[0056] The frame 10 of the standardization device 100 provided by the present invention can be manufactured by cutting and welding steel plates and / or square tubes, or can be manufactured by machining after integral casting. Then, the six faces of the frame 10, the inner connection of the frame 10, and the through hole 110 are machined accordingly to ensure positioning accuracy. The manufacturing process of the frame 10 is simple and can be mass-produced, thereby effectively reducing the manufacturing cost of the entire standardization device 100.

[0057] The use process of the standardization device 100 provided by the present invention is as follows:

[0058] The pipe loader is used to shape the pipe 200 to be processed into a standard posture, and then the standardization device 100 is inserted into the pipe 200 to be processed, and the pipe 200 to be processed is fixed in the standardization device 100 by combining the pipe fixing component and the pipe positioning component and / or combining the positioning parts. At this time, the pipe modules formed by different pipes 200 to be processed have the same or matching relative positions of the pipes to be processed and the frame, for example, the pipes 200 to be processed have a uniform center height and a relatively fixed length extending from the frame 10.

[0059] The lifting holes 110 on the standardized device 100 are utilized and a truss manipulator is used for lifting. Since different pipe modules have the same lifting holes 110, the design of the truss manipulator only needs to be suitable for the lifting holes of the standardized device 100 without considering the different shapes and sizes of the pipes.

[0060] By using the reference surfaces (such as the second surface 103 and the sixth surface 107) on the standardization device 100, which has a uniform regular shape and flatness, it is convenient for the conveying system to convey each pipe module and place it in the three-dimensional warehouse for storage. When designing these conveying devices and three-dimensional warehouses, only the specifications of the standardization device 100 need to be considered, without considering the specific shape and size of the pipe.

[0061] By utilizing the uniform outer dimensions of the standardized device 100 and the positioning holes provided on the standardized device 100, accurate positioning, reliable clamping and centrifugal rotation of pipe fittings can be achieved during processes such as grinding, assembly and welding, thereby facilitating intelligent grinding, intelligent assembly and intelligent welding of pipe fittings and pipes.

[0062] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
