Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, and more specifically, to a material unloading platform for building construction projects. Background Technology

[0002] In the field of building construction, unloading platforms are key equipment for material transfer, and their performance and safety directly affect construction efficiency and the safety of workers. Traditional unloading platform designs often suffer from problems such as simple structure and limited functionality, making it difficult to meet the diverse and efficient construction needs of modern building projects. Specifically, traditional unloading platforms mainly have the following problems: Insufficient structural stability: Some traditional unloading platforms lack sufficient consideration for structural stability in their design. Especially when facing complex and changing construction environments, such as uneven ground or strong winds, they are prone to swaying or tilting, posing a serious threat to the safety of workers and materials. Poor adaptability: Different building construction projects have different construction needs, and have different requirements for the size, height, load-bearing capacity, etc. of the unloading platform; however, traditional unloading platforms are often designed in a fixed manner, which makes it difficult to make flexible adjustments according to actual construction needs, resulting in great limitations in practical applications. Unstable material placement: During the unloading process, the stability of the material placement is directly related to construction efficiency and safety. However, some traditional unloading platforms lack sufficient anti-slip measures in the design of the material placement area, which makes the material prone to sliding or tipping over during lifting or movement, causing inconvenience and risks to the operation. Summary of the Invention

[0003] The present invention aims to solve at least one of the above-mentioned technical problems.

[0004] To solve the above problems, the present invention provides a building construction unloading platform, including an unloading platform body, hinged supports, a leg telescopic mechanism, and a support structure. A plurality of the hinged supports are respectively disposed on the outer side of the unloading platform body. The first end of the leg telescopic mechanism is hinged to the hinged supports, and the second end of the leg telescopic mechanism is used to swing towards or away from the unloading platform body. The first end and the second end of the leg telescopic mechanism are their opposite ends. The support structure is connected to the second end of the outrigger telescopic mechanism, which is used to extend or retract to a set length; the outrigger telescopic mechanism has at least a downward tilting state, and the second end of the outrigger telescopic mechanism in the downward tilting state is lower than the first end.

[0005] The present invention provides a material unloading platform for building construction (hereinafter referred to as unloading platform), which, compared with the prior art, has, but is not limited to, the following technical effects: During operation at the destination, the unloading platform features multiple hinged supports on its outer surface. These supports allow the outrigger extension mechanisms connected to the hinged supports to swing. Specifically, the second end of each outrigger extension mechanism can swing away from the platform body, extending outwards. Furthermore, the outrigger extension mechanism is at least in a downward tilted state, where the second end is lower than the first end. As each outrigger extension mechanism swings outwards in its downward tilted state, it gradually extends. During this extension, the second end moves both away from the unloading platform and downwards, ultimately supporting the ground at the second end along a downward angle. At this point, the multiple support extension mechanisms act like "crab legs," providing stable support and improving the structural stability of the unloading platform. This is especially beneficial in complex and changing construction environments, such as uneven ground or strong winds, preventing swaying or tilting and enhancing the safety of personnel and materials.

[0006] Furthermore, the unloading platform body is a scissor-type screw lifting platform, which includes a base, a scissor telescopic mechanism, a screw drive assembly, and the unloading platform body. The top of the scissor telescopic mechanism is connected to the unloading platform body, and the bottom of the scissor telescopic mechanism is connected to the base.

[0024] See Figures 1-3 An embodiment of the present invention provides a material unloading platform for building construction, comprising a material unloading platform body 1, hinged supports 2, a leg telescopic mechanism 3, and a support structure 4. Multiple hinged supports 2 are respectively disposed on the outer side of the material unloading platform body 1. The first end of the leg telescopic mechanism 3 is hinged to the hinged supports 2, and the second end of the leg telescopic mechanism 3 is used to swing towards or away from the material unloading platform body 1. The first end and the second end of the leg telescopic mechanism 3 are their opposite ends. The support structure 4 is connected to the second end of the outrigger telescopic mechanism 3, which is used to extend or retract to a set length; the outrigger telescopic mechanism 3 has at least a downward tilting state, and the second end of the outrigger telescopic mechanism 3 in the downward tilting state is lower than the first end.

[0025] In this embodiment, during the use of the unloading platform at the destination, multiple hinged supports 2 are installed on the outer side of the unloading platform body 1. Therefore, the outrigger extension mechanism 3 connected to the hinged supports 2 can swing. Specifically, the second end of the outrigger extension mechanism 3 can swing away from the unloading platform body 1, that is, the outrigger extension mechanism 3 can swing outward and unfold. In addition, the outrigger extension mechanism 3 has at least a downward tilting state, and the second end of the outrigger extension mechanism 3 in the downward tilting state is lower than the first end. Thus, after each outrigger extension mechanism 3 in the downward tilting state swings outward and unfolds, it can gradually extend. During the gradual extension process, the second end will move away from the unloading platform while moving downward, and finally, the support structure 4 of the second end is supported on the ground in a downward tilting direction. At this time, the multiple support extension mechanisms are like "crab legs" that are stably supported on the ground, which improves the structural stability of the unloading platform. Especially when facing complex and changeable construction environments, such as uneven ground and strong winds, it will not sway or tilt, and the safety of operators and materials is higher.

[0026] It is understandable that the outrigger telescopic mechanism 3 is crucial for the unloading platform to be stably supported on the ground. Specifically, the horizontal distance between the support structure 4 at the second end of the outrigger telescopic mechanism 3 and the main body 1 of the unloading platform is critical. For stable support, such as... Figures 1-3 As shown, the distance between the support structure 4 and the unloading platform body 1 needs to be relatively far. However, in this embodiment, the support telescopic mechanism in the downward tilting state can achieve the extension of the support structure 4 to make it farther away while also grounding the support structure 4 through a seemingly "simple" extension movement. It can be seen that this is not a conventional setting.

[0027] Furthermore, in this embodiment, since the second end of the outrigger telescopic mechanism 3 can also swing and retract towards the unloading platform body 1, that is, swing and retract inward, when the unloading platform needs to be moved, by retracting each outrigger telescopic mechanism 3, the space occupied by the unloading platform can be reduced, and the unretracted outrigger telescopic mechanism 3 can be prevented from interfering with the external environment when it is moved with the unloading platform.

[0028] Moreover, when the unloading platform is used in building construction, the surrounding ground environment is sometimes quite complex, such as uneven ground or piles of debris. In this case, since the outrigger extension mechanism 3 has the ability to swing outward and inward, the swing angle of the outrigger extension mechanism 3 can be adjusted so that the second end support structure 4 can be grounded after extension, thereby minimizing the impact of the complex ground environment on its stability.

[0029] See Figures 1-2The unloading platform body 1 is a scissor-type screw 132 lifting platform. The scissor-type screw 132 lifting platform includes a base 11, a scissor telescopic mechanism 12, a screw drive assembly 13, and an unloading platform body 14. The top of the scissor telescopic mechanism 12 is connected to the unloading platform body 14, and the bottom of the scissor telescopic mechanism 12 is connected to the base 11. The screw drive assembly 13 is mounted on the base 11 and is used to drive the scissor telescopic mechanism 12 to extend and retract.

[0030] In this embodiment, the unloading platform body 1 is a scissor-type screw 132 lifting platform. The scissor-type screw 132 lifting platform is the same as the existing scissor-type screw 132 lifting platform, and has the following main components: scissor telescopic mechanism 12 and unloading platform body 14 and base 11 located at its top and bottom respectively. The screw drive assembly 13 can drive the scissor telescopic mechanism 12 to extend and retract in the vertical direction, so as to drive the unloading platform body 14 at its top to rise and fall.

[0031] In this embodiment, since the unloading platform body 1 is a scissor-type screw 132 lifting platform, that is, it has a lifting function, compared with the traditional fixed unloading platform, the unloading platform of this embodiment can be flexibly adjusted in height according to actual construction needs.

[0032] See Figures 1-3 The scissor telescopic mechanism 12 includes multiple scissor arms, each including a top X-shaped support arm and a bottom X-shaped support arm 121; the unloading platform body 14 has an upper groove on its lower side, and an upper sliding groove 1411 is provided on the opposite side wall of the upper groove. Two upper sliders 1412 are slidably connected in each upper sliding groove 1411. The top ends of the two supports of the top X-shaped support arm are respectively hinged to the corresponding upper sliders 1412 in the corresponding side upper sliding grooves 1411. The lead screw drive assembly 13 includes a motor 131, a lead screw 132, two threaded blocks 133, and a connecting rod 134. A lower groove 111 is provided on the upper side of the base 11. The lead screw 132 is rotatably connected to the lower groove 111. The two threaded blocks 133 are threadedly sleeved 25 onto the lead screw 132. A sliding groove 112 is provided on the opposite sidewall of the lower groove 111. Two sliding blocks 113 are slidably connected in each sliding groove 112. The bottom ends of the two arms of the bottom X-shaped support arm 121 are respectively hinged to the corresponding sliding blocks 113 in the corresponding sliding groove 112. The two threaded blocks 133 are respectively hinged to the corresponding sliding blocks 113 via the connecting rod 134. The motor 131 is driven by the lead screw 132 and is used to drive the two threaded blocks 133 on the lead screw 132 to move relative to or away from each other, so that the scissor telescopic mechanism 12 extends or retracts.

[0033] Understandably, similar to existing technologies, the scissor telescopic mechanism 12 serves as a lifting execution frame, comprising scissor arms. In this embodiment, the scissor arms employ multi-layer scissor arms, thereby enabling a larger lifting stroke to meet the requirements of loading / unloading materials at higher positions during building construction. Figure 2 As shown, the multi-layer scissor arms are arranged in two sets, one on the left and one on the right. The transverse connecting rod between the two sets of scissor arms ensures that the left and right sets of scissor arms lift and lower synchronously without deviation. These are all conventional technologies, so we will not go into further detail about the scissor telescopic mechanism 12 or the scissor screw 132 lifting platform.

[0034] Unlike conventional technologies, the multi-layer scissor arm in this embodiment is not fixed at one end and sliding at the other, but rather slidable at both ends. Specifically, the lead screw 132 of the lead screw drive assembly 13 has two threaded blocks 133, and two sliding blocks 113 are provided in the sliding grooves 112 on the side wall of the lower groove 111. Both threaded blocks 133 are connected to the corresponding sliding blocks 113 on the corresponding side through connecting rods 134. At the same time, one sliding block 113 is hinged to one arm of the bottom X-shaped support arm 121, and the other sliding block 113 is hinged to the other arm of the bottom X-shaped support arm 121. Thus, when the motor 131 drives the lead screw 132 to rotate, the two sliding blocks 113 move relative to each other or in opposite directions, so that the scissor extension mechanism 12 extends or retracts.

[0035] In order to achieve the goal of "when the motor 131 drives the lead screw 132 to rotate, the two lower sliders 113 move relative to each other or move in opposite directions", the lead screw 132 can be designed as a threaded symmetrical structure, that is, the thread of half the length of the lead screw 132 is left-handed, and the thread of the other half of the length of the lead screw 132 has a symmetrical right-handed direction. Both of these parts of the lead screw 132 are connected to the matching threaded blocks 133.

[0036] In this embodiment, through the design of the above structure, when the scissor telescopic mechanism 12 extends and retracts to drive the unloading platform body 14 to rise and fall, the scissor telescopic mechanism 12 slides at both ends, so it can always be in the center of the unloading platform body 14 and the base 11, thereby further improving the stability of the entire unloading platform.

[0037] Among them, such as Figure 3 As shown, the connecting rod 134 can be used as a rod that connects the threaded block 133 to the support arm in the bottom X-shaped support arm 121, or it can be used as a rod that is hinged to the support arm and the corresponding lower slider 113. That is, the rod is movably inserted through the support arm in the bottom X-shaped support arm 121, and one end of the rod is connected to the lower slider 113 (which can be a fixed connection), and the other end is connected to the threaded block 133 (which can be a fixed connection).

[0038] Optionally, the scissor telescopic mechanism 12 includes a multi-layer scissor arm, which includes a top X-shaped support arm and a bottom X-shaped support arm 121; the lower side of the unloading platform body 14 is provided with an upper groove, and the opposite sidewall of the upper groove is provided with an upper sliding groove 1411. An upper slider 1412 and an upper fixing block are slidably connected in each upper sliding groove 1411; the top ends of the two supports of the top X-shaped support arm are respectively hinged to the upper slider 1412 and the upper fixing block in the corresponding side upper sliding groove 1411. The lead screw drive assembly 13 includes a motor 131, a lead screw 132, a threaded block 133, and a connecting rod 134. A lower groove 111 is provided on the upper side of the base 11. The lead screw 132 is rotatably connected to the lower groove 111. The threaded block 133 is threadedly sleeved 25 and connected to the lead screw 132. A sliding groove 112 is provided on the opposite side wall of the lower groove 111. A sliding block 113 and a lower fixing block are slidably connected in each sliding groove 112. The bottom ends of the two arms of the bottom X-shaped support arm 121 are respectively hinged to the sliding block 113 and the lower fixing block of the corresponding side sliding groove 112. The threaded block 133 is hinged to the corresponding sliding block 113 through the connecting rod 134.

[0039] In at least one other embodiment, the multi-layer scissor arm employs a conventional method of fixing one end and sliding the other. Specifically, the lead screw 132 of the lead screw drive assembly 13 has a threaded block 133, and each sliding groove 112 on the side wall of the lower groove 111 is provided with a lower slider 113 and a lower fixing block. The threaded block 133 is connected to the lower slider 113 on the corresponding side via a connecting rod 134. At the same time, the lower slider 113 is hinged to one arm of the bottom X-shaped support arm 121, and the lower fixing block is hinged to the other arm of the bottom X-shaped support arm 121. Thus, when the motor 131 drives the lead screw 132 to rotate, the lower slider 113 on the same side will move towards or away from the lower fixing block, thereby extending or shortening the scissor telescopic mechanism 12.

[0040] Optionally, the bottom of the unloading platform body 1 is equipped with wheels 51, so that the unloading platform can move around the construction site and is highly flexible.

[0041] Optionally, such as Figure 2 As shown, the unloading platform may also include a hydraulic cylinder 52, which is located inside the scissor telescopic mechanism 12, specifically between the left and right sets of scissor arms. The spatial position of the hydraulic cylinder 52 does not affect the movement of the scissor telescopic mechanism 12. The top end of the hydraulic cylinder 52 is connected to the unloading platform body 14, and the bottom end of the hydraulic cylinder 52 is connected to the base 11. The hydraulic cylinder 52 is used to assist the lifting operation of the scissor telescopic mechanism 12 and improve the load-bearing capacity of the unloading platform.

[0042] See Figure 1Optionally, the sliding groove 112 extends through to the outer side of the base 11, and the hinge support 2 is installed on the outer side of the base 11 where the sliding groove 112 is provided, and the hinge support 2 is arranged at both ends of the sliding groove 112. The hinged support 2 is used to adjust the pitch angle (i.e., the angle with the horizontal plane) of the outrigger telescopic mechanism 3 so that the outrigger telescopic mechanism 3 can switch between at least a horizontal state and a downward tilting state; the outrigger telescopic mechanism 3 has a plate-like structure, and when the outrigger telescopic mechanism 3 is in a horizontal state, the second end of the outrigger telescopic mechanism 3 is used to swing towards the base 11 so that the two outrigger telescopic mechanisms 3 on the same side can jointly cover the sliding groove 112 on the same side.

[0043] In this embodiment, the sliding groove 112 extends along the Y-axis to the outer side of the base 11, meaning the sliding groove 112 is exposed, which facilitates the installation of the sliding block 113. The sliding groove 112 can be a dovetail groove, and the sliding block 113 can be a dovetail block. The sliding block 113 can be a split structure / splitting structure, with one part inserted into the sliding groove 112 from the outside of the base 11 and the other part inserted into the sliding groove 112 from the lower groove 111, thus forming the sliding block 113.

[0044] In this embodiment, when the unloading platform moves around the site, the sliding groove 112 is exposed and, due to its proximity to the ground, is easily affected by dust and impurities stirred up from the ground. This dust and impurities will enter the sliding groove 112, affecting the smoothness of the sliding block 113. Therefore, the outrigger telescopic mechanism 3 is not always in a downward tilting state, but can adjust its pitch angle to change to other states. Specifically, the hinged support 2 can adjust the pitch angle of the outrigger telescopic mechanism 3, for example, changing it from a downward tilting state to a horizontal state. After switching to a horizontal state, the outrigger telescopic mechanism 3 swings inward, allowing it to better cover the sliding groove 112.

[0045] It is understandable that when the outrigger telescopic mechanism 3 is fully retracted, the two outrigger telescopic mechanisms 3 located on the same side of the base 11 can swing inward without interfering with each other. After swinging inward, they can be joined together to jointly shield the sliding groove 112 on that side. With the sliding groove 112 shielded, the unloading platform will be better protected from the exposed sliding groove 112 when moving and transferring, reducing or even avoiding the impact of dust and impurities.

[0046] It is understandable that, since the opposite side walls (the left and right side walls shown in the figure) of the lower groove 111 are provided with lower grooves 112, the outrigger telescopic mechanism 3 can be provided in four groups of two. One group is set on the same side as one lower groove 112, and the other group is set on the same side as another lower groove 112. The hinged supports 2 at the ends of the two outrigger telescopic mechanisms 3 in one group are respectively located at the two ends of the corresponding lower groove 112.

[0047] It should be noted that after the outrigger telescopic mechanism 3 swings inward, it not only does not obstruct the movement of the unloading platform, but also, when it swings inward in a horizontal state, a set of outrigger telescopic mechanisms 3 can provide excellent protection for the sliding groove 112. It is clear that this is not a simple conventional setting.

[0048] Optionally, the outrigger telescopic mechanism 3 is a plate-shaped structure to ensure the shielding effect on the sliding groove 112. The outrigger telescopic mechanism 3 includes an outer plate and an inner plate, with the inner plate slidably connected to the outer plate and capable of sliding relative to the outer plate. One end of the outer plate is connected to the hinge support 2. In this embodiment, a locking hole may be provided at the end of the outer plate away from the hinge support 2, and a locking bolt is connected to the locking hole to lock and fix the inner plate.

[0049] Optionally, to facilitate the movement of the unloading platform, a push rod 53 can be provided on the rear side of the unloading platform body 1 to facilitate pushing / pulling the unloading platform to move.

[0050] See Figure 2 Optionally, the support structure 4 includes a support rod 41 and a support pad 42. The second end of the outrigger telescopic mechanism 3 is provided with a threaded hole. The support rod 41 is threaded to the threaded hole, and the support pad 42 is fixed to the bottom end of the support rod 41.

[0051] In this embodiment, the support structure 4 can be a height-adjustable structure, which includes a support rod 41 and a support pad 42 fixed at the bottom of the support rod 41. The support rod 41 is threaded to the threaded hole at the second end of the support telescopic mechanism, specifically threaded to the threaded hole at the end of the inner plate away from the base 11. By adjusting the position of the support rod 41 in the threaded hole, the height of the support structure 4 can be adjusted, making grounding more flexible.

[0052] See Figure 4Optionally, the hinged support 2 includes an upper support plate 21, a lower support plate 22, a telescopic shaft 23, and a horizontal moving structure. The upper support plate 21 and the lower support plate 22 are respectively fixed on the base 11. The horizontal moving structure is disposed on the upper support. The bottom end of the telescopic shaft 23 is hinged to the lower support plate 22, and the top end of the telescopic shaft 23 is hinged to the movable part of the horizontal moving structure. One end of the telescopic plate is movably sleeved outside the telescopic shaft 23. The horizontal moving structure is used to adjust the angle between the telescopic shaft 23 and the vertical direction. When the telescopic shaft 23 is parallel to the vertical direction, the leg telescopic structure is in the downward tilting state.

[0053] In this embodiment, as Figure 4 As shown, when it is necessary to change the outrigger telescopic mechanism 3 from a tilted state to a horizontal state, its movable part can be driven to move horizontally through a horizontal moving structure. After the movable part moves horizontally, the top end of the telescopic shaft 23 hinged to it will also move accordingly. At the same time, in order to match the movement of the top end of the telescopic shaft 23, the telescopic shaft 23 will adaptively change its length. After the top end of the telescopic shaft 23 moves, the entire telescopic shaft 23 will change its angle with the vertical direction, thereby causing the outrigger telescopic mechanism 3, which is movably connected to it, to change its pitch angle, thus naturally changing to a horizontal state. Figure 4 As shown, when the telescopic shaft 23 is parallel to the vertical direction, the outrigger telescopic mechanism 3 is in a downward tilting state; when the top of the telescopic shaft 23 moves away from the base 11 with the moving part of the horizontal moving structure, the downward tilting angle of the outrigger telescopic mechanism 3 gradually increases, providing more flexibility for the stability of the unloading platform; when the bottom of the telescopic shaft 23 moves closer to the base 11 with the moving part of the horizontal moving structure, the outrigger telescopic mechanism 3 will gradually change from a downward tilting state to a horizontal state, or even an upward tilting state.

[0054] It is understood that the telescopic shaft 23 includes an outer shaft and an inner shaft. The inner shaft is slidably connected inside the outer shaft. The bottom end of the outer shaft is hinged to the lower support plate 22. The top end of the inner shaft is hinged to the movable part of the horizontal moving structure. The end of the outrigger telescopic mechanism 3 is movably sleeved on the outer shaft, which does not affect the movement of the inner shaft relative to the outer shaft.

[0055] See Figure 4 Optionally, the horizontal movement includes a lead screw 24 and a threaded sleeve 25. A recessed groove 211 is provided on the lower side of the upper support plate 21. The lead screw 24 is rotatably connected to the upper support plate 21, and a portion of the lead screw 24 is located within the recessed groove 211. The threaded sleeve 25 is threadedly connected to the lead screw 24 and slidably connected within the recessed groove 211. The top end of the telescopic shaft 23 is hinged to the threaded sleeve 25. The threaded sleeve 25 is the movable part of the aforementioned horizontal movement structure.

[0056] In this embodiment, when it is necessary to adjust the angle between the telescopic shaft 23 and the vertical direction, the lead screw 24 can be turned. The rotation of the lead screw 24 will drive the sliding mechanism slidably connected in the recessed groove 211 to slide, thereby causing the angle between the telescopic shaft 23 and the vertical direction to change. The structure is simple and reliable, and will not affect the inward swing, outward swing or pitch angle change of the outrigger telescopic mechanism 3.

[0057] See Figure 1 and Figure 5 Optionally, the unloading platform body 14 includes a platform 141, a fence 142, an unloading plate 143, and a locking structure 144. The fence 142 surrounds the platform 141 and forms an inlet / outlet on one side of the platform 141. The unloading plate 143 is located at the inlet / outlet, and the bottom end of the unloading plate 143 is hinged to the platform 141. The unloading plate 143 is used to open or close the inlet / outlet. The locking structure 144 is disposed on the platform 141. The locking structure 144 is used to lock the unloading plate 143 in the closed inlet / outlet state, or to release the unloading plate 143 to the open inlet / outlet state.

[0058] In this embodiment, after the unloading platform body 14 rises to the required height, the unloading plate 143 can be unlocked by the locking structure 144. At this time, the unloading plate 143 can be opened outward, and the end of the outward-opening unloading plate 143 can overlap the corresponding floor slab. Materials on the unloading platform body, especially heavier materials, can be dragged onto the unloading plate 143 first, and then onto the floor slab; conversely, materials on the floor slab can also be dragged onto the unloading platform body 14. When the unloading platform body 14 does not need to receive or discharge materials, the unloading plate 143 can be rotated to the closed inlet and outlet state, and then the locking structure 144 can be used to lock the unloading plate 143.

[0059] Of course, for lighter materials, it is not necessary to open the unloading plate 143. Instead, the materials can be picked up manually and handed directly to the workers on the floor, or the workers on the floor can hand them directly to the workers on the unloading platform body 14. Optionally, the end of the unloading plate 143 is provided with a hook 1431, which is used to provide gripping force and can better grip the floor.

[0060] When the unloading plate 143 is in the closed state, it works in conjunction with the guardrail 142 to protect the perimeter of the platform 141, preventing materials on the platform 141 from slipping and improving safety. The locking structure 144 may include a snap-fit ​​part 1441 and a snap-fit ​​mating part 1442. The snap-fit ​​mating part 1442 is fixedly connected to the platform 141. After the snap-fit ​​part 1441 snaps into the snap-fit ​​mating part 1442, it can lock the unloading plate 143 in the closed state. After the snap-fit ​​part 1441 disengages from the snap-fit ​​mating part 1442, the unloading plate 143 is no longer locked and can be released to the open inlet / outlet state.

[0061] Optionally, the platform 141 is provided with an anti-slip structure. For example, a high-friction anti-slip plate can be laid on the platform 141; or anti-slip patterns can be provided on the platform 141. When materials are placed, in conjunction with the guardrail 142, the materials are more effectively prevented from slipping.

[0062] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
