Description

Technical Field

[0001] This invention relates to the field of bending equipment technology, and more specifically, to a bending and forming equipment for power tower structural components. Background Technology

[0002] A power tower consists of components such as the tower body, crossarms, conductors, and insulators. These components are typically connected to each other using structural members and fastening bolts. These structural members include, for example... Figure 1 The bending of angle steel, long U-shaped bending plates, and right-angle bending plates in power towers is mostly achieved through bending. However, the following problems exist in the actual bending process: 1. Bending equipment lacks flexibility, and can only form structural components of the same size at a time; 2. Structural components of different shapes cannot be bent on the same bending equipment, requiring the use of specialized bending equipment or only allowing workers to manually control the bending of one end at a time, resulting in a complex bending process. Therefore, we propose a bending and forming equipment for power tower structural components. Summary of the Invention

[0003] The purpose of this invention is to provide a bending and forming equipment for power tower structural components, which solves at least one of the above-mentioned technical problems and improves the flexibility, bending types, and bending efficiency of the bending equipment.

[0004] This invention provides a bending and forming device for power tower structural components, including a support assembly, several pads, a first cylinder, and several feeding assemblies;

[0005] The support assembly includes a worktable with several forming grooves, and first limiting blocks parallel to the forming groove opening direction are distributed on both sides of the forming grooves.

[0006] There is a pad block directly above each of the forming grooves. The first limiting blocks on both sides of the forming groove limit the two ends of the pad block respectively. The pad block moves at the opening of the forming groove along the direction parallel to the opening of the forming groove and is fixed on the first limiting block by bolts.

[0007] The first cylinder is fixedly mounted on the workbench by a support frame. A bending component is fixedly mounted on the output shaft of the first cylinder. The output shaft of the first cylinder pushes the bending component down to press and bend the structural parts on the pad.

[0008] The feeding assembly includes an electric slide table and a positioning plate fixedly installed at the output end of the electric slide table. The electric slide table is fixedly installed on the workbench via a support plate. The positioning plate has a positioning groove for limiting the structural components. The bottom surface of the positioning groove is coplanar with the upper surface of the fixedly installed pad. The positioning plate is slidably connected to the support plate. The movement direction of the positioning plate is parallel to the movement direction of the corresponding pad.

[0009] As an optional solution to the technical solution of this invention, it also includes a positioning ring plate;

[0010] A support block is fixedly installed at the intersection of several forming grooves, and a positioning ring plate is inserted and fitted on the periphery of the support block. The number and position of the side of the positioning ring plate correspond one-to-one with the number and position of the forming groove, and is used for positioning the end of the angle steel to be formed.

[0011] The upper surface of the support block is coplanar with the upper surface of the pad block after it is installed and fixed.

[0012] As an optional solution of the technical solution in this invention document, a plurality of first limiting blocks are provided with scale lines, the starting zero point of the scale lines is the center point of the support block, and the scale lines gradually increase along the opening direction of the corresponding forming groove.

[0013] As an optional solution of the technical solution in this invention document, the pad is screwed with two sets of L-shaped limiting blocks symmetrical about the center plane of the pad, and the two sets of L-shaped limiting blocks form a limiting channel for limiting the two sides of the structural component to be bent.

[0014] By adopting the above technical solution, the width of the limiting channel can be adjusted by replacing L-shaped limiting blocks of different widths, thus satisfying the limiting requirements of structural components of different sizes.

[0015] As an optional solution of the technical solution in this invention document, the bending assembly includes an adjusting frame, which is slidably connected to a support frame. The adjusting frame has several grooves, and a threaded rod is rotatably connected to the adjusting frame. A bending head component is threadedly fitted onto the threaded rod, and the bending head component is slidably fitted with the grooves. A spring-loaded component is installed at the bottom of the bending head component for pressing the structural component.

[0016] As an optional solution to the technical solution of this invention, the bending head component includes a support column, a bending column and a top block. The support column is slidably engaged with the slide groove, and the threaded rod is threadedly engaged with the support column. The opening direction of the slide groove is parallel to the opening direction of the corresponding forming groove below.

[0017] A fixed base is fixedly installed at the bottom of the support column, and a fixed block is fixedly installed at the bottom of the fixed base. The fixed block has several limiting grooves and a connecting groove communicating with the limiting grooves. An adjusting block is slidably connected in the limiting groove, and a first elastic element is installed in the limiting groove. One end of the first elastic element is fixedly connected to the adjusting block, and the other end is fixedly connected to the fixed block.

[0018] The bending column is fixedly installed with several connecting blocks corresponding to the connecting grooves. The connecting blocks and the adjusting blocks are fixedly connected by flexible steel cables. An arc plate is fixedly installed on the bending column. The arc plate is coaxial with the bending column and is inserted into the fixed block. The bending column is rotatably connected to the fixed block through the arc plate. A bending opening is provided on the bending column for bending structural components.

[0019] The top block is located below the bending column and the fixing block, and is closer to the adjusting block. The top block is slidably connected to the fixing block through the guide column. The opening of the bending hole abuts against the upper surface of the top block. The two ends of the fixing seat are fixedly installed with second limiting blocks, which are used to limit the end of the bending column.

[0020] By adopting the above technical solution, the tension of the first elastic element is applied to the bending column through the adjusting block and the flexible steel cable, so that the bending column has a clockwise torsional force. The opening of the bending hole acts on the upper surface of the top block, causing the top block to move away from the fixed block until it reaches the maximum limit. During the bending operation, the lower surface of the top block contacts the surface of the structural component. As the downward pressure is applied, the relative distance between the top block and the fixed block decreases, thereby causing the top block to push the bending column to rotate counterclockwise. The first elastic element is stretched under the action of the flexible steel cable, realizing the bending operation of the structural component. After the operation is completed, the first elastic element drives the bending column and the top block to return to their original positions.

[0021] As an optional solution to the technical solution of this invention, the elastic member includes a pressure block and a plurality of second elastic members;

[0022] The bottom of the top block is provided with a guide groove, the pressure block slides in the guide groove, the second elastic element is located in the guide groove, one end of the second elastic element is fixedly connected to the top block, and the other end is fixedly connected to the pressure block, and the total elastic force of the first elastic elements is greater than the total elastic force of the second elastic elements.

[0023] By adopting the above technical solution, during the downward bending operation, the pressure block contacts the structural component first. The total elastic force of the first elastic elements is greater than the total elastic force of the second elastic elements, causing the pressure block and the top block to slide relative to each other. This achieves the initial pressing of the pressure block onto the surface of the structural component, preventing the feeding assembly from affecting the positioning of the structural component when it detaches. During the actual bending operation, the top block presses the structural component again onto a larger contact area. Therefore, this invention has two pressing processes with different effects, thereby ensuring the accuracy and stability of the position of the structural component during positioning and bending.

[0024] As an optional solution of the technical solution in this invention document, a second cylinder is fixedly installed on the positioning plate. The pushing direction of the second cylinder is parallel to the moving direction of the pad block. A push plate is fixedly installed at the output end of the second cylinder. The push plate is used to push the structural component placed in the positioning groove onto the pad block.

[0025] As an optional solution of the technical solution in this invention document, two sets of positioning blocks are inserted into both sides of the positioning plate, which are symmetrical about the center surface of the positioning groove. The positioning blocks are close to the open end of the positioning groove, and the distance between the two sets of positioning blocks is equal to the distance between the two sets of L-shaped limiting blocks.

[0026] As an optional solution to the technical solution of this invention document, it also includes an unloading assembly, which includes a third cylinder and an unloading rod, with the third cylinder fixedly installed at the bottom of the pad block;

[0027] The pad has a guide hole, the unloading rod slides with the guide hole, the output shaft of the third cylinder is fixedly mounted with a top plate, a third elastic element is fitted on the unloading rod, one end of the third elastic element is fixed on the unloading rod, and the other end abuts against the bottom of the pad, and the bottom of the unloading rod abuts against the top plate.

[0028] An unloading plate is installed at an angle inside the forming groove, and the height of the unloading plate gradually decreases from the middle of the workbench to the edge.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] 1. The present invention, through the setting of adjustable pads, can adapt to the support of non-bending areas of structural components of different lengths. The setting of multiple pads can simultaneously bend multiple groups of angle steel of the same or different sizes, thereby improving the bending efficiency and flexibility of structural components.

[0031] 2. This invention, through the coordinated support of multiple sets of pads, can realize the bending of structural parts of different shapes, improve the adaptability of forming equipment to the processing of structural parts of different shapes, and has the function of multi-purpose machine.

[0032] 3. In the bending of angle steel, the feeding component of this invention can position and transport the unbent angle steel plate to the corresponding pad, thereby realizing automatic feeding and bending, which greatly improves the bending efficiency of angle steel. When bending the ends of long U-shaped bending plates and right-angle bending plates, the feeding component can move to a set position according to the length of the structural component or its end, and limit the ends of the long U-shaped bending plates and right-angle bending plates, thereby reducing the difficulty of positioning the unbent structural components and realizing rapid positioning. Moreover, when the long U-shaped bending plates and right-angle bending plates are bent, both ends are bent and formed at the same time, further improving the bending efficiency.

[0048] 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.

[0049] Reference Figures 2 to 5A bending and forming device for power tower structural components includes a support assembly 1, several pads 2, and a positioning ring plate 3. The support assembly 1 includes a workbench 11 with several forming grooves 12 arranged in an array on the workbench 11. In this embodiment, there are four forming grooves 12, corresponding to the four sides of the workbench 11. Several first limiting blocks 13 are fixedly installed on the surface of the workbench 11. Each forming groove 12 has a first limiting block 13 on both sides, parallel to the opening direction of the forming groove 12 and symmetrical about the center plane of the forming groove 12. The bottom of the pad 2 is in contact with the surface of the workbench 11, and the pad 2 is located directly above the corresponding forming groove 12 and between two first limiting blocks 13. The length of block 2 is equal to the distance between the first limiting blocks 13 distributed on both sides of the corresponding forming groove 12, that is, both ends of the pad block 2 are in contact with the corresponding first limiting blocks 13. The first limiting blocks 13 effectively limit the movement direction of the pad block 2. The first limiting blocks 13 are provided with mounting holes 14. The two ends of the pad block 2 are provided with T-slots 21. The shank of the bolt passes through the mounting hole 14, and the head of the bolt is inserted into the T-slot 21. The pad block 2 is fixed on the first limiting block 13 by the locking nut and the bolt. The unloading plate 15 is installed at an angle in the forming groove 12. The height of the unloading plate 15 gradually decreases from the middle of the workbench 11 to the edge. When the bent structural parts fall onto the unloading plate 15, they can slide out automatically, reducing the difficulty of unloading.

[0050] A support block 16 is fixedly installed at the intersection of several forming grooves 12 (center of workbench 11). A positioning ring plate 3 is inserted and fitted around the support block 16. The number and position of the side of the positioning ring plate 3 correspond one-to-one with the number and position of the forming grooves 12. It is used to position the end of the angle steel to be formed. When forming long U-shaped bending plates and right-angle bending plates, the positioning ring plate 3 can be removed. The upper surface of the support block 16 is coplanar with the upper surface of the fixed pad 2. When forming long U-shaped bending plates and right-angle bending plates, the support block 16 can effectively support them, thereby improving the stability of the support.

[0051] The first limiting block 13 is provided with a scale line. The starting zero point of the scale line is the center point of the support block 16. The scale line gradually increases along the opening direction of the corresponding forming groove 12. Therefore, when adjusting the position of the pad block 2, the size of the non-bending part when forming angle steel, long U-shaped bending plate and right angle bending plate can be calculated by the scale value, reducing the difficulty of adjusting the pad block 2. For example, by calculating the dimensions of the non-bending part of the angle steel, the dimension L of the side of the pad 2 away from the center point of the support block 16 is obtained, and the dimension D of the positioning edge of the positioning ring plate 3 corresponding to the pad 2 is obtained. Therefore, the dimension of the non-bending part of the angle steel is the difference between L and D. By reverse derivation, the position scale of the pad 2 that needs to be moved is obtained, thereby realizing the rapid determination of the adjustment position of the pad 2. The dimension of the non-bending part of the long U-shaped bending plate is the distance between the bending edges of the two pads 2 on the opposite side. The scale value corresponding to the bending point of the right-angle bending plate can also be calculated by combining the same method of difference and summation, thereby adjusting the position of the corresponding pad 2. This will not be elaborated further here.

[0052] A control panel 17 is installed on the workbench 11 for program control of the bending and forming equipment. A support frame 18 is fixedly installed on the workbench 11. Several outwardly extending support plates 19 are fixedly installed on the periphery of the workbench 11, and the support plates 19 correspond to the positions of the forming groove 12.

[0053] Reference Figure 5 and Figure 6 The pad 2 has first positioning holes 22 and threaded holes 24 at both ends. The two sets of first positioning holes 22 are symmetrical about the center plane of the pad 2, and the two sets of threaded holes 24 are symmetrical about the center plane of the pad 2. The L-shaped limiting block 23 is inserted into the pad 2 through the first positioning hole 22. The L-shaped limiting block 23 has a through hole 25. The bolt passes through the through hole 25 and is threaded into the threaded hole 24 to fix the L-shaped limiting block 23 on the pad 2. The two L-shaped limiting blocks 23 form a limiting channel for limiting the two sides of the structural component to be bent. Therefore, the width of the limiting channel can be adjusted by replacing L-shaped limiting blocks 23 of different widths (the positions of the insertion position and the through hole 25 remain relatively unchanged), thereby satisfying the limiting of structural components of different sizes. The pad 2 has a guide hole 26, and the axis of the guide hole 26 is coplanar with the center plane of the pad 2.

[0054] Reference Figure 2 , Figures 7 to 13A first cylinder 4 is fixedly installed on the support frame 18. A bending assembly 5 is fixedly installed on the output shaft of the first cylinder 4. The bending assembly 5 includes an adjusting frame 51. The adjusting frame 51 is slidably connected to the support frame 18 through a guide rod 52. Several sliding grooves 53 are opened on the adjusting frame 51. A threaded rod 54 is rotatably connected to the adjusting frame 51. A bending head component 55 is threadedly engaged on the threaded rod 54. The bending head component 55 includes a support column 551. The support column 551 is slidably engaged with the sliding groove 53. The threaded rod 54 is threadedly engaged with the support column 551. The opening direction of the sliding groove 53 is parallel to the opening direction of the corresponding forming groove 12 below, thereby ensuring that the bending head component 55 moves in the same direction as the pad block 2 when the displacement is adjusted.

[0055] A fixing seat 552 is fixedly installed at the bottom of the support column 551, and a fixing block 553 is fixedly installed at the bottom of the fixing seat 552. The fixing block 553 has several limiting grooves 554 and connecting grooves 555 communicating with the limiting grooves 554. An adjusting block 556 is slidably connected within the limiting groove 554, and a first elastic element 557 is installed within the limiting groove 554. One end of the first elastic element 557 is fixedly connected to the adjusting block 556, and the other end is fixedly connected to the fixing block 553. The bending head component 55 also includes a bending column 558, on which several connecting grooves corresponding to the connecting grooves 555 are fixedly installed. The connecting block 559 can move within the connecting groove 555. The connecting block 559 and the adjusting block 556 are fixedly connected by a flexible steel cable 5510. The first elastic element 557 drives the adjusting block 556 to move, thereby tightening the flexible steel cable 5510. An arc plate 5511 is fixedly installed on the bending column 558. The arc plate 5511 is coaxial with the bending column 558 and is inserted into the fixing block 553. The bending column 558 is rotatably connected to the fixing block 553 through the arc plate 5511. A bending opening 5512 is provided on the bending column 558 for bending structural components.

[0056] The bending head component 55 also includes a top block 5513, which is located below the bending column 558 and the fixing block 553, and is closer to the adjusting block 556. The top block 5513 is slidably connected to the fixing block 553 via a guide post 5514, and the opening of the bending port 5512 abuts against the upper surface of the top block 5513. The tension of the first elastic element 557 acts on the bending column 558 through the adjusting block 556 and the flexible steel cable 5510, causing the bending column 558 to... Figure 9The position shown has a clockwise torsional force. The opening of the bending port 5512 acts on the upper surface of the top block 5513, causing the top block 5513 to move away from the fixed block 553 until it reaches the maximum limit. During the bending operation, the lower surface of the top block 5513 contacts the surface of the structural component. As the downward pressure is applied, the relative distance between the top block 5513 and the fixed block 553 decreases, thereby causing the top block 5513 to push the bending column 558 to rotate counterclockwise. The first elastic element 557 is stretched under the action of the flexible steel cable 5510, realizing the bending operation of the structural component. After the operation is completed, the first elastic element 557 drives the bending column 558 and the top block 5513 to return to their original positions.

[0057] The bottom of the top block 5513 is provided with a guide groove 5515. A pressure block 5516 is slidably connected in the guide groove 5515. Several second elastic elements 5517 are installed in the guide groove 5515. One end of the second elastic element 5517 is fixedly connected to the top block 5513, and the other end is fixedly connected to the pressure block 5516. The total elastic force of the several first elastic elements 557 is much greater than the total elastic force of the several second elastic elements 5517. The two ends of the fixed seat 552 are fixedly installed with second limiting blocks 5518. The second limiting blocks 5518 are used to limit the end of the bent column 558. During the downward bending operation, the pressure block 5516 contacts the structural component first. The total elastic force of the first elastic elements 557 is greater than the total elastic force of the second elastic elements 5517, causing the pressure block 5516 and the top block 5513 to slide relative to each other. This achieves the initial pressing of the pressure block 5516 onto the surface of the structural component, preventing the feeding assembly 6 from affecting the positioning of the structural component. In the actual bending operation, the top block 5513 presses the structural component again with a larger contact area. Therefore, the present invention has two pressing processes with different effects, thereby ensuring the accuracy and stability of the position of the structural component during the positioning and bending process.

[0058] Reference Figure 2 and Figure 14Several feeding components 6 are installed on corresponding support plates 19. Each feeding component 6 includes an electric slide 61 fixedly installed on the support plate 19 and a positioning plate 62 fixedly installed on the output end of the electric slide 61. The positioning plate 62 has a positioning groove 63. The bottom surface of the positioning groove 63 is coplanar with the upper surface of the fixedly installed pad 2. The width of the positioning groove 63 is not greater than the width of the forming groove 12. The positioning plate 62 is slidably connected to the support plate 19 through a guide rail 64. The movement direction of the positioning plate 62 is parallel to the movable direction of the pad 2. A second cylinder 65 is fixedly installed on the positioning plate 62. The pushing direction of the second cylinder 65 is parallel to the moving direction of the pad 2. A push plate 66 is fixedly installed at the output end of the second cylinder 65. The push plate 66 is used to push the structural component placed in the positioning groove 63 onto the pad 2. One end of the structural component to be bent is placed against the tail end of the positioning groove 63. The output shaft of the electric slide 61 drives the positioning plate 62 and the structural component to move until the positioning plate 62 contacts the pad block 2. The output shaft of the second cylinder 65 drives the push plate 66 to move, thereby pushing the unbent angle steel structural component onto the pad block 2.

[0059] It should be noted that long U-shaped and right-angled bent plates require manual or robotic feeding. Before feeding, the positioning ring plate 3 must be removed. The feeding assembly 6 can also be used for positioning the ends of long U-shaped and right-angled bent plates. Specifically, the distance between the positioning plates 62 on opposite sides is adjusted so that the maximum distance between the tail ends of the two sets of positioning grooves 63 is equal to the total length of the unbent long U-shaped bent plate. When the distance between the two sets of positioning grooves 63 does not meet the distance requirements, the push plate 66 can be moved by the second cylinder 65 to control the distance between the two sets of push plates 66 to position the end of the unbent long U-shaped bent plate. After the structural component is initially pressed by the pressure block 5516, the feeding assembly 6 moves backward to avoid interference with the bending of the structural component. The same method is used for end positioning of the unbent right-angled bent plate, which will not be described in detail here.

[0060] The positioning plate 62 has several second positioning holes 67 on both sides. Two positioning blocks 68 are inserted into the corresponding second positioning holes 67 to adjust the positioning width of the positioning groove 63. The two sets of positioning blocks 68 are symmetrical about the center face of the positioning groove 63, and the positioning blocks 68 are close to the open end of the positioning groove 63. The distance between the two sets of positioning blocks 68 is equal to the distance between the two sets of L-shaped limiting blocks 23. When it is necessary to adjust the positioning width of the positioning groove 63, the positioning of structural parts of different widths can be achieved by changing the size of the positioning blocks 68.

[0061] Reference Figure 6The forming equipment also includes a discharge assembly 7, which includes a third cylinder 71 and a discharge rod 72. The third cylinder 71 is fixedly installed at the bottom of the pad 2, and the discharge rod 72 is slidably engaged with the guide hole 26. The output shaft of the third cylinder 71 is fixedly installed with a top plate 73. A third elastic element 74 is fitted on the discharge rod 72. One end of the third elastic element 74 is fixed to the discharge rod 72, and the other end abuts against the bottom of the pad 2. The bottom of the discharge rod 72 abuts against the top plate 73 (or can be fixed to the top plate 73). After the angle steel is bent and formed, the discharge rod 72 pushes through the guide hole 26, thereby lifting the angle steel. Under the action of the tilt angle and gravity, the angle steel falls into the forming groove 12 and slides out under the action of the discharge plate 15, realizing the automatic discharge process.

[0062] Working principle: Adjust the position of the pad 2 according to the length of the non-bending part of the structural component. The shank of the bolt passes through the mounting hole 14 and the head of the screw is inserted into the T-slot 21. The pad 2 is fixed on the first limit block 13 by the locking nut and the bolt to keep the pad 2 stable. By rotating the threaded rod 54, the bending position of the bending head component 55 corresponding to the pad 2 is adjusted synchronously to keep the bending position accurate.

[0063] When bending the angle steel, the positioning ring plate 3 is inserted into the periphery of the support block 16. The unbent angle steel plate is precisely placed in the positioning groove 63 by the conveying equipment or the robot, with one end abutting against the tail end of the positioning groove 63. The output shaft of the electric slide 61 drives the positioning plate 62 and the structural component to move until the positioning plate 62 contacts the pad block 2. The output shaft of the second cylinder 65 drives the push plate 66 to move, pushing the unbent angle steel structural component onto the pad block 2 and making one end abut against the positioning ring plate 3.

[0064] The output shaft of the first cylinder 4 drives the bending assembly 5 to descend. The pressure block 5516 first contacts the structural component. The total elastic force of the first elastic elements 557 is greater than the total elastic force of the second elastic elements 5517, causing the pressure block 5516 to slide relative to the top block 5513. This achieves the initial pressing of the pressure block 5516 onto the surface of the structural component. The feeding assembly 6 resets, and the output shaft of the first cylinder 4 continues to press down. The lower surface of the top block 5513 contacts the surface of the structural component. As the downward pressure is applied, the top block... The relative distance between the top block 5513 and the fixed block 553 decreases, causing the top block 5513 to push the bending column 558 to rotate counterclockwise, thus performing a bending operation on the structural component. During the counterclockwise rotation of the bending column 558, the first elastic element 557 is stretched under the action of the flexible steel cable 5510. After the operation is completed, as the output shaft of the first cylinder 4 returns, the tension of the first elastic element 557 acts on the bending column 558 through the adjusting block 556 and the flexible steel cable 5510, causing the bending column 558 to... Figure 9The position shown has a clockwise torsional force, and the opening of the bending opening 5512 acts on the upper surface of the top block 5513, causing the top block 5513 to move away from the fixed block 553 until it reaches the maximum limit, thereby resetting the bending column 558 and the top block 5513.

[0065] The output shaft of the third cylinder 71 drives the unloading rod 72 to push through the guide hole 26, thereby lifting the angle steel. Under the action of the tilt angle and gravity, the angle steel falls into the forming groove 12 and slides out under the action of the unloading plate 15, realizing the automated bending and forming of the angle steel.

[0066] When bending long U-shaped and right-angled bending plates, the position of the positioning plates 62 on the opposite or adjacent sides is adjusted by the feeding assembly 6, so that the positioning grooves 63 of the two sets of positioning plates 62 limit the ends of the structural parts to be bent. The material is released manually or by a robot. The bending process of long U-shaped and right-angled bending plates is similar to that of angle steel forming, and the bending process will not be described in detail. After the two ends of the long U-shaped or right-angled bending plate are formed simultaneously, the material is unloaded again manually or by a robot, thereby realizing the forming process.

[0067] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
