Description

Technical Field

[0001] The present invention relates to the technical field of the installation of gates in water conservancy projects, and particularly to a construction method for the installation of plane gates. Background Art

[0002] The construction method for the installation of gates in water conservancy projects is as follows: use a lifting device to lift the gate leaf above the top height of the gate slot, and after aligning with the slot opening, slowly lower it and place it in the gate slot; repeat this process to place each section of the gate leaf into the gate slot and splice them into a whole, and then complete various installation tests of the gate. The hoisting of the gate leaf generally uses a crawler crane. The gate leaf is transported to the vicinity of the gate bottom plate at the corresponding hole position of the gate through a construction access road, and the crawler crane is used as the lifting device to lift the gate leaf into the gate slot for splicing, installation and debugging, and confirm the opening and closing performance and stability of the gate operation. Hoisting the gate leaf with a crawler crane can only be carried out during the dry season of the river (that is, when the riverbed is in a waterless state), which does not meet the construction period requirements; moreover, limited by the height of the gate slot, the position of the hole, etc., a large-tonnage crawler crane is often required to meet the hoisting requirements, and the turning process of the crawler crane will damage the concrete surface layer, and the large hoisting height and hoisting distance also make the hoisting construction more dangerous. Summary of the Invention

[0003] In view of the above defects existing in the prior art, the present invention provides a construction method for the installation of plane gates to solve the problem that the hoisting of the gate leaf of the existing plane gate by a crawler crane can only be carried out during the dry season of the river.

[0004] The present invention is realized by adopting the following technical solutions:

[0005] A construction method for the installation of plane gates includes the following steps:

[0006] S1. Pre-lay track beams for the horizontal movement of the hoisting and transfer mechanism on the tops of several flood discharge gates, and connect the track beams in a horizontal through connection. Lay transverse tracks for the lateral movement of the transfer trolley above the gate slot of each flood discharge gate. Install a plane gate on each flood discharge gate, and install a hoist above the gate slot where the plane gate is installed;

[0007] S2. Transfer the top section of the gate leaf to the hoisting and transfer mechanism by a truck crane, and then transfer the top section of the gate leaf to the transfer trolley by the hoisting and transfer mechanism. The transfer trolley transports the top section of the gate leaf to below the hoist, and then the hoist lifts the top section of the gate leaf on the transfer trolley;

[0008] S3. The hoisting and transfer mechanism continues to transfer the next section of the gate leaf to the transfer trolley. The transfer trolley transports the next section of the gate leaf to below the hoist. The hoist lowers the top section of the gate leaf, and uses the inter-joint connection components to assemble the top section of the gate leaf with the next section of the gate leaf. After assembly, lift them as a whole;

[0009] S4. Repeat step S3, and assemble two adjacent single-section gate leaves up and down through the said inter-node connection component until the remaining gate leaves are assembled, so as to complete the assembly of the gate leaves on the hoist.

[0010] S5. Conduct a static load balance test on the assembled gate leaves on the hoist. After passing the test, disassemble the transverse movement track, and use the hoist to lower the gate leaves into the gate slot to complete the installation of the plane gate. After the installation is completed, conduct a full-stroke opening and closing test under the condition of no water.

[0011] Further, the inter-node connection component includes two inter-node connection plates and a first connection pin shaft. Upper connection holes and lower connection holes are respectively opened at both ends of the two inter-node connection plates. The two inter-node connection plates are arranged at intervals on the next-section gate leaf. A slot is formed between the two inter-node connection plates. The first connection pin shaft is adaptively penetrated through the lower connection holes of the two inter-node connection plates. The upper-section gate leaf is provided with a lifting lug plate for inserting into the slot. The lifting lug plate is provided with a lifting lug hole corresponding to the upper connection hole. The lifting lug plate is inserted into the slot of the two inter-node connection plates, and the upper connection hole and the lifting lug hole are coaxially formed in the transverse direction to form a splicing pin hole. A detachable second connection pin shaft is penetrated through the splicing pin hole to realize the assembly between the upper-section gate leaf and the next-section gate leaf.

[0012] Further, an auxiliary lifting mechanism is installed on the main beam of the upper-section gate leaf. The output end of the auxiliary lifting mechanism is detachably connected to the end of the second connection pin shaft, and the second connection pin shaft is penetrated through the splicing pin hole by the auxiliary lifting mechanism.

[0013] Further, the auxiliary lifting mechanism is a hand-operated lifting device.

[0014] Further, the auxiliary lifting mechanism is a chain block. The chain block includes an upper hook, a sprocket box, a sprocket, a lifting chain and a lower hook. The upper hook is fixed on the sprocket box. The upper hook is detachably connected to the main beam of the upper-section gate leaf. The sprocket is installed in the sprocket box and is wound around the lifting chain. The lifting end of the lifting chain is provided with the lower hook. The end of the second connection pin shaft is hung on the lower hook.

[0015] Further, in step S2, the hoist is provided with a pulley block. The pulley block is provided with a pin shaft hole. The top-section gate leaf is provided with a lifting lug hole adapted to the pin shaft hole. A third connection pin shaft is penetrated between the pin shaft hole and the lifting lug hole to realize the connection between the hoist and the top-section gate leaf.

[0016] Further, in step S1, the transfer trolley has a receiving groove for accommodating a single-section door leaf. The hoisting and transfer mechanism is used to vertically place the single-section door leaf into the receiving groove. Adjusting members are respectively arranged on the longitudinal two sides of the receiving groove, and the adjusting members are configured to adjust the position of the single-section door leaf in the receiving groove.

[0017] Further, in step S1, a support frame is built at the top opening of the gate slot, and a steel rail for the transfer trolley to travel is laid above the support frame.

[0018] Further, in step S1, the truck crane flips the single-section door leaf by 90 degrees and places it in the middle of the track beam. The hoisting and transfer mechanism hoists the single-section door leaf on the track beam and moves it to the upstream position of the transverse track. Then, the hoisting and transfer mechanism places the single-section door leaf into the receiving groove of the transfer trolley, and then the hoisting and transfer mechanism returns to the initial position.

[0019] Further, the hoisting and transfer mechanism includes a hoisting main body, a traveling assembly arranged at the bottom of the hoisting main body, a traveling driving assembly for driving the traveling assembly to move along the track beam, and a hoisting driving assembly. The traveling assembly is in sliding fit with the track beam. A hoisting member for hoisting a single-section door leaf and a hoisting driving assembly for driving the hoisting member to lift and lower are arranged on the hoisting main body.

[0020] Compared with the prior art, the beneficial effects of the present invention at least include:

[0021] The construction method for installing the plane gate of the present invention uses a hoist as the main lifting equipment, and cooperates with a hoisting and transfer mechanism and a transfer trolley to complete the installation of the door leaf. It does not need to be installed underwater during the dry season, ensuring the construction period. Moreover, the present invention can use the hoist to lift and lock the entire gate during the flood season when water is flowing, without the need to invest in larger-tonnage lifting equipment, reducing the hoisting risk and mechanical investment. In addition, the door leaf of the gate of the present invention is assembled section by section from top to bottom, and then using the lifting capacity of the hoist, compared with the traditional assembly on land, it occupies less space and has more flexible environmental adaptability.

[0040] Now, the exemplary embodiments will be described more comprehensively with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; on the contrary, these embodiments are provided so that this invention will be more complete and comprehensive, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, so their repeated description will be omitted.

[0041] The words expressing positions and directions described in the present invention are all illustrated by taking the accompanying drawings as examples, but can be changed according to needs, and all changes made are included in the protection scope of the present invention.

[0042] As Figures 1 to 17 shown, a construction method for installing a plane gate provided by the present invention includes the following steps:

[0043] S1. On the top of several drain sluices 1, track beams 13 for the horizontal movement of the hoisting and transfer mechanism 2 are pre - laid in advance. Each track beam 13 is connected in a through - hole manner in the horizontal direction. Above the gate slot 11 of each drain sluice 1, a transverse movement track 12 for the lateral movement of the transfer trolley 3 is laid. Each drain sluice 1 is installed with a plane gate, and a hoist 5 is installed above the gate slot 11 where the plane gate is installed.

[0044] S2. The truck crane 4 is used to transfer the top section gate leaf 61 onto the hoisting and transfer mechanism 2, and then the hoisting and transfer mechanism 2 transfers the top section gate leaf 61 onto the transfer trolley 3. The transfer trolley 3 transports the top section gate leaf 61 to below the hoist 5, and then the hoist 5 hoists the top section gate leaf 61 on the transfer trolley 3.

[0045] S3. The hoisting and transfer mechanism 2 continues to transfer the lower section gate leaf 62 to the transfer trolley 3. The transfer trolley 3 transports the lower section gate leaf 62 to below the hoist 5. The hoist 5 lowers the top section gate leaf 61, and the top section gate leaf 61 and the lower section gate leaf 62 are assembled using the inter - joint connection assembly 7. After assembly, they are lifted as a whole.

[0046] S4. Repeat step S3. Assemble two adjacent single-section gate leaves up and down through the inter-node connection component 7 until the remaining gate leaves are assembled, so as to complete the assembly of the gate leaf 6 on the hoist 5.

[0047] S5. Conduct a static load balance test on the assembled gate leaf 6 on the hoist 5. After passing the test, disassemble the transverse movement track 12, and use the hoist 5 to lower the gate leaf 6 into the gate slot 11 to complete the installation of the plane gate. After the installation is completed, conduct a full-stroke opening and closing test under the condition of no water.

[0048] In this embodiment, the installation principle of the plane gate is as follows: Install the hoist 5 above the gate slot 11 of the plane gate to be installed, and use the hoist 5 to assemble the single-section gate leaves one by one from top to bottom, so as to complete the assembly of the gate leaf 6 on the hoist 5. Then, cooperate with the lifting and transfer mechanism 2 and the transfer trolley 3 to transport the single-section gate leaves to the lower part of the hoist 5 one by one. The hoist 5 first hoists the top gate leaf 61. After the next gate leaf 62 is transported to directly below the hoist 5, the hoist 5 lowers the top gate leaf 61, and assemble the next gate leaf 62 and the top gate leaf 61 through the inter-node connection component 7. After the two single-section gate leaves are assembled, the hoist 5 hoists the assembled gate leaf to a certain height and waits for the next gate leaf 62 to be transported over. Repeat the above assembly process until all the gate leaves are assembled. After the gate leaf 6 is assembled, use the hoist 5 to conduct a static load balance test on the assembled gate leaf 6. After the test is qualified, lower the gate leaf 6 into the gate slot 11 through the hoist 5 to complete the installation of the plane gate. After the plane gate is installed, conduct a full-stroke opening and closing test under the condition of no water.

[0049] The key to the construction method of the plane gate installation of the present invention lies in using the hoist 5 as the main lifting equipment and cooperating with the lifting and transfer mechanism 2 and the transfer trolley 3 to complete the installation of the gate leaf 6, without the need to install it in the water during the dry season, ensuring the construction period; moreover, the present invention can use the hoist 5 to lift and lock the entire gate during the flood season when the water is flowing, without the need to invest in a larger-tonnage lifting equipment, reducing the lifting risk and mechanical investment, and having more advantages compared with the method of using a crawler crane to hoist the gate. In addition, the gate leaf 6 of the present invention is assembled from the top down, taking advantage of the lifting capacity of the hoist 5, occupying less space compared with the traditional assembly on land.

[0050] The present invention pre-lays track beams 13 for the horizontal movement of the lifting and transfer mechanism 2 on the tops of several flood discharge gates 1 in advance, and the track beams 13 are connected in a through manner in the horizontal direction. In this way, the lifting and transfer mechanism 2 can pass through each flood discharge gate 1 in turn, achieving the "assembly line" transportation effect and realizing the continuous transfer of single-section gate leaves by multiple flood discharge gates 1, greatly shortening the construction period.

[0051] The present invention uses the hoisting and transfer mechanism 2 and the transfer trolley 3 to assist in transporting the gate leaf, which can significantly improve the construction efficiency and safety, and has the following unexpected effects:

[0052] (1) Reduce the dependence on large hoisting equipment and save costs. The transportation of the traditional gate leaf 6 relies on large crawler cranes (such as those above 200t), while the present invention uses the combined transportation of the hoisting and transfer mechanism 2 and the rail-mounted transfer trolley 3 to transport a single-section gate leaf, and the total cost is significantly reduced compared to renting a large crawler crane.

[0053] (2) Adapt to complex site conditions. The present invention moves the hoisting and transfer mechanism 2 along the track beam 13, without the need for additional hoisting space, and can adapt to narrow space operations. At the same time, the hoisting and transfer mechanism 2 is used to accurately position the gate leaf to avoid collision with surrounding buildings.

[0054] (3) Shorten the construction period and optimize the process connection. The hoisting and transfer mechanism 2 of the present invention moves along the direction perpendicular to the water flow, and the transfer trolley 3 transfers the gate leaf along the direction parallel to the water flow. The two are connected in an orderly manner, reducing the equipment entry / exit time and realizing the continuous operation ability. After the present invention uses the hoisting and transfer mechanism 2 and the transfer trolley 3 to assist in the assembly of the gate leaf 6, the construction period can be shortened by 30%.

[0055] (5) Reduce manual intervention and lower safety risks. The transfer trolley 3 of the present invention can be remotely controlled or driven automatically along a preset path, reducing the exposure time of personnel in dangerous areas (such as high altitudes and deep foundation pits). After using the transfer trolley 3 for transportation, the safety accident rate in the installation link of the gate leaf 6 is reduced.

[0056] Therefore, the present invention cooperates with the hoisting and transfer mechanism 2 and the transfer trolley 3 to complete the transportation of the gate leaf 6, making the transportation of the gate leaf 6 accurate, modular, and low-risk, and is especially suitable for the comprehensive requirements of modern water conservancy projects for efficiency, safety, and cost.

[0057] The upper and lower adjacent single-section gate leaves of the present invention are assembled through the inter-joint connection component 7. Compared with the traditional welding method, the present invention utilizes the lifting capacity of the hoist 5 to realize the vertical progressive assembly of the gate leaf 6, and has the following unexpected effects:

[0058] (1) Greatly reduce the hoisting cost. Since the gate leaf 6 of the present invention is assembled in a progressive manner, there is no need to rely on large hoisting equipment, and the rental cost can be saved.

[0059] (2) The present invention assembles the upper and lower adjacent single-section gate leaves through the inter-joint connection component 7, which can reduce the risk caused by poor manual welding. At the same time, it saves the need to erect a scaffolding or use an aerial work platform for high-altitude welding, greatly reducing the cost, and facilitating the on-site installation and later disassembly and maintenance of the gate.

[0060] In the present invention, in step S5, in cooperation with the hoist 5, the horizontal and vertical degrees of the gate can be quickly adjusted to meet the requirements, ensuring that the gate is installed and fixed in place at one time, improving the operation efficiency, reducing the labor intensity of workers, and reducing the cost of gate installation.

[0061] The static load balance test of the present invention includes the verticality adjustment test and the horizontality adjustment test of the gate leaf 6. Among them, the verticality deviation is 1 / 1000 of the gate height, and the horizontality deviation is not more than 5 mm. The present invention can use cast iron blocks to adjust the center of gravity and attitude of the entire gate leaf 6 until the verticality and horizontality of the gate meet the requirements.

[0062] As a preferred embodiment, the inter-joint connection assembly 7 includes two inter-joint connecting plates 71 and a first connecting pin 72. Upper and lower connecting holes are respectively formed at both ends of the two inter-joint connecting plates 71. The two inter-joint connecting plates 71 are arranged at intervals on the lower adjacent gate leaf 62. A slot is formed between the two inter-joint connecting plates 71. The first connecting pin 72 is adaptively inserted through the lower connecting holes of the two inter-joint connecting plates 71. The upper adjacent gate leaf 63 is provided with a lifting lug plate 64 for inserting into the slot. The lifting lug plate 64 is provided with a lifting lug hole corresponding to the upper connecting hole. The lifting lug plate 64 is inserted into the slot of the two inter-joint connecting plates 71, and the upper connecting hole and the lifting lug hole are coaxially arranged transversely to form a splicing pin hole 74. A detachable second connecting pin 73 is adaptively inserted into the splicing pin hole 74 to realize the assembly between the upper adjacent gate leaf 63 and the lower adjacent gate leaf 62.

[0063] In this embodiment, through the inter-joint connecting plate 71, the first connecting pin 72 and the second connecting pin 73, the assembly of the upper and lower adjacent single-section gate leaves is realized, eliminating the welding process between adjacent gate leaves, reducing the construction difficulty, reducing the construction time, and having the advantages of fast assembly speed, high efficiency and reliable quality through the structures of the slot and the splicing pin hole 74; in addition, through the mutual cooperation of the first connecting pin 72 and the second connecting pin 73, the stability of the assembly between the two gate leaves is improved, ensuring the safety performance of the gate leaf 6.

[0064] As a preferred embodiment, an auxiliary lifting mechanism 8 is installed on the main beam of the upper adjacent gate leaf 63. The output end of the auxiliary lifting mechanism 8 is detachably connected to the end of the second connecting pin 73, and the second connecting pin 73 is inserted into the splicing pin hole 74 through the auxiliary lifting mechanism 8.

[0065] In this embodiment, the second connecting pin 73 is installed through the auxiliary lifting mechanism 8, reducing the intensity of manual pin insertion; moreover, the second connecting pin 73 is connected to the auxiliary lifting mechanism 8, preventing the second connecting pin 73 from falling during the pin insertion process and ensuring the safety of the installation.

[0066] As a preferred embodiment, the auxiliary lifting mechanism 8 is a hand-operated lifting device.

[0067] In this embodiment, the auxiliary lifting mechanism 8 is preferably a hand-operated lifting device. Due to its power-free feature, the hand-operated lifting device can quickly set up a temporary lifting system. Compared with electric lifting devices, it can reduce the energy consumption cost. Moreover, the hand-operated lifting device can perform lifting tasks in places without power supply or with strict explosion-proof requirements, ensuring the continuity of operations. In addition, the hand-operated lifting device has a simple mechanical structure, low failure rate, and a service life of more than 10 years. Therefore, using a hand-operated lifting device has the characteristics of low cost, high safety, high adaptability, and high reliability.

[0068] As a preferred embodiment, the auxiliary lifting mechanism 8 is a chain block. The chain block includes an upper hook 81, a sprocket box 82, a sprocket, a lifting chain 83, and a lower hook 84. The upper hook 81 is fixed on the sprocket box 82, and the upper hook 81 is detachably connected to the main beam of the upper section of the gate leaf 63. The sprocket is installed in the sprocket box 82 and is wound around the lifting chain 83. The lifting end of the lifting chain 83 is provided with the lower hook 84, and the end of the second connecting pin 73 is hung on the lower hook 84.

[0069] In this embodiment, the auxiliary lifting mechanism 8 of the present invention uses a chain block to assist in the installation of the second connecting pin 73. The specific operation process is as follows: By pulling the lifting chain 83, the second connecting pin 73 can be raised or lowered, which can assist in fixing the second connecting pin 73 in the splicing pin hole 74, realizing the convenient installation of the second connecting pin 73. At the same time, it is beneficial for later disassembly (by pulling the lifting chain 83, the second connecting pin 73 can be pulled out of the splicing pin hole 74), solving the problems of difficult installation and inconvenient disassembly of traditional connecting pins.

[0070] As a preferred embodiment, in step S2, the hoist 5 is provided with a pulley block 51. The pulley block 51 is provided with a pin hole, and the top section of the gate leaf 61 is provided with a lug hole adapted to the pin hole. A third connecting pin is passed through the pin hole and the lug hole to realize the connection between the hoist 5 and the top section of the gate leaf 61. In this embodiment, the hoist 5 and the top section of the gate leaf 61 are connected and fixed by a third connecting pin, which is convenient to operate, simplifies the connection method, and reduces the assembly cost.

[0071] As a preferred embodiment, in step S1, the transfer trolley 3 has a receiving groove 31 for accommodating a single section of the gate leaf. The lifting and transfer mechanism 2 is used to vertically place a single section of the gate leaf into the receiving groove 31. Adjusting members 32 are respectively arranged on the longitudinal two sides of the receiving groove 31, and the adjusting members 32 are configured to adjust the position of the single section of the gate leaf in the receiving groove 31.

[0072] In this embodiment, the transfer trolley 3 receives a single-section gate leaf through the receiving groove 31, which is beneficial to the rapid transfer of the hoisting and transfer mechanism 2, saves the transfer time, and thus shortens the construction period. The position of the single-section gate leaf in the receiving groove 31 is adjusted by the adjusting member 32. On the one hand, it ensures that the gate leaf does not shake during the transfer process, and on the other hand, it ensures the assembly accuracy of the gate leaf on the hoist 5 subsequently. Preferably, the adjusting member 32 of the present invention is an adjusting screw rod. By rotating the adjusting screw rod, the position of the single-section gate leaf in the receiving groove 31 can be adjusted. It can be understood that the rotation of the adjusting screw rod can be manual or electric, and no specific limitation is made here.

[0073] As a preferred implementation manner, in step S1, a support frame 14 is built at the top opening of the gate slot 11, and a steel rail for the transfer trolley 3 to travel is laid above the support frame 14.

[0074] In this embodiment, by laying the steel rail on the support frame 14, the movement of the transfer trolley 3 can be realized, and the construction is simple and convenient. After the gate leaf 6 is assembled, by disassembling the steel rail and the support frame 14, the gate can be placed in the gate slot 11.

[0075] As a preferred implementation manner, in step S1, the truck crane 4 flips a single-section gate leaf by 90 degrees and places it in the middle of the track beam 13. The hoisting and transfer mechanism 2 hoists the single-section gate leaf on the track beam 13 and moves it to the upstream position of the transverse movement track 12. Then, the hoisting and transfer mechanism 2 places the single-section gate leaf in the receiving groove 31 of the transfer trolley 3, and then the hoisting and transfer mechanism 2 returns to the initial position.

[0076] In this embodiment, on the land side, the transport vehicle unloads all the gate leaves in the stacking area, and then the truck crane 4 flips a single-section gate leaf by 90 degrees so that the gate leaf can be assembled vertically. After that, the truck crane 4 places the flipped single-section gate leaf in the middle of the track beam 13. The hoisting and transfer mechanism 2 hoists the single-section gate leaf in the middle of the track beam 13 and moves along the track beam 13. When it moves above the transfer trolley 3, the single-section gate leaf is lowered into the receiving groove 31 of the transfer trolley 3. The transfer trolley 3 moves downstream along the transverse movement track 12 to directly below the hoist 5, and then the hoist 5 hoists the single-section gate leaf.

[0077] As a preferred implementation manner, in step S1, the hoisting and transfer mechanism 2 includes a hoisting main body, a traveling assembly provided at the bottom of the hoisting main body, a traveling driving assembly for driving the traveling assembly to move along the track beam 13, and a hoisting driving assembly. The traveling assembly is in sliding fit with the track beam 13. A hoisting member for hoisting a single-section gate leaf and a hoisting driving assembly for driving the hoisting member to lift and lower are provided on the hoisting main body.

[0078] In this embodiment, a single-section gate leaf is lifted and transported by a lifting member. Compared with traditional ground transportation, lifting can achieve precise positioning and continuous operation, reduce intermediate links in ground handling (such as multiple loading, unloading, and transfer), improve operation efficiency, and the lifting can adapt to complex environments and is more flexible. At the same time, the lifting and lowering of the lifting member is controlled by a lifting drive assembly to achieve aerial operation, release ground space, and improve site utilization rate. The walking drive assembly drives the walking assembly to repeatedly move along the track beam 13, so that the hoisting main body can move smoothly. Smooth hoisting can reduce the risks of collision and falling. Since the present invention adopts the method of transporting the gate leaf 6 of the sluice gate section by section, the gate leaf needs to be transferred frequently. The long-term use cost of the hoisting equipment is usually lower than the total cost of leasing multiple small equipment or manual handling, reducing the construction cost. The hoisting and transferring mechanism 2 of this embodiment is preferably an inspection gantry crane. Correspondingly, an inspection gate slot 9 is provided on the land side. Of course, in other embodiments, the hoisting and transferring mechanism 2 can also be a bridge crane, a tower crane, a forklift boom, or a vacuum suction lifting tool.

[0079] The sluice gate 1 of the present invention includes 9 holes, each with a width of 14 m. One plane working gate and one hoist 5 are respectively arranged in each hole. The installation methods of the 1#-9# working gates are the same. The transportation paths of the hoisting and transferring mechanism 2 and the transfer trolley 3 are as Figure 13 indicated by the arrows.

[0080] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Without departing from the principle and purpose of the present invention, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the invention. All these changes should fall within the protection scope of the claims of the present invention.
