Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of Bailey frames, and in particular to a Bailey frame deformation monitoring device. Background Art
[0002] Bailey frames are prefabricated steel highway bridges primarily used for rapidly erecting temporary or semi-permanent bridge structures to meet the urgent needs of military operations and post-war reconstruction. Due to their simple structure, quick assembly, and high load-bearing capacity, Bailey frames are widely used in military, engineering, and emergency rescue applications. Their modular design, rapid construction, and flexible adaptability have made them an indispensable temporary bridge solution in both military and civilian engineering. In modern engineering construction, Bailey frames not only play a key role in emergency rescue but also demonstrate their irreplaceable value as temporary support structures in large-scale infrastructure projects.
[0003] In the prior art, when Bailey frames are used in large-scale infrastructure construction, it is usually necessary to arrange multiple plumb bobs at different locations on the Bailey frame to form a spatial monitoring network. By comparing the deviations between different locations of the Bailey frame structure and the theoretical plumb line, the verticality changes or local deformations of the structure can be intuitively reflected. This network has many advantages, such as low cost, no need for complex equipment, intuitive reflection of verticality changes, simple operation, and suitability for rapid on-site deployment. However, when plumb bobs are used for a long time in a humid environment, rust may form on the surface of the plumb bob, making it easy for the plumb bob to shift its center of gravity and affect its suspension stability during use. This is not conducive to accurately monitoring the deformation of the Bailey frame and cannot meet people's demand for rapid monitoring of Bailey frame deformation. Summary of the Invention
[0004] In view of the defects in the prior art, the present invention provides a Bailey frame deformation monitoring device.
[0005] A Bailey frame deformation monitoring device includes a device body, the top of the device body is connected and fixed to the Bailey frame by a set connecting mechanism, two storage slots are provided inside the device body, and rotating blocks are rotatably installed inside the two storage slots. The ends of the two rotating blocks away from the rotating parts are connected to the mounting blocks by two first electric telescopic rods, and a box is installed at the center position of the bottom of the device body and the bottoms of the two mounting blocks by the set mounting mechanism. A plumb line is provided at the bottom of the box, and a protective cover for protecting the plumb line is also provided at the bottom of the box. A spraying mechanism for spraying a rust inhibitor onto the surface of the plumb line and an anti-falling mechanism for preventing the plumb line from falling are provided inside the protective cover.
[0006] Optionally, the connecting mechanism includes two fixing rods, both of which are installed at the center of the top of the device body. A groove is provided on the top of the two fixing rods, and a double-headed screw rod is rotatably installed inside the two grooves. Two connecting plates are threadedly installed on the outer walls of the two double-headed screw rods.
[0007] Optionally, the mounting mechanism includes two fixed plates installed at the bottom of the device body and the two mounting blocks, and limiting plates are slidably installed inside the two fixed plates. The outer walls on both sides of the box are provided with limiting grooves that are compatible with the limiting plates.
[0008] Optionally, screw rods are threadedly installed inside the two fixing plates, and the adjacent ends of the two screw rods are rotatably connected to their corresponding limiting plates.
[0009] Optionally, a first winding wheel and two second winding wheels are rotatably installed inside the box, and the outer walls of the first winding wheel and the two second winding wheels respectively wind up the first steel wire rope and the second steel wire rope, and the end of the first steel wire rope away from the first winding wheel is connected to the plumb line, and the ends of the two second steel wire ropes away from the second winding wheel are both connected to the protective cover.
[0010] Optionally, a cylindrical cushion is installed at the center of the interior of the protective cover, a through hole is opened at the center of the interior of the cushion, and the first steel wire rope is in contact with the inner wall of the through hole.
[0011] Optionally, the spraying mechanism includes a shell installed on the outer wall of the protective cover, a rust inhibitor is placed inside the shell, and a liquid injection port is provided on the top of the shell.
[0012] Optionally, the inner wall of the protective cover is provided with two slide grooves, and sliders are installed inside the two slide grooves. An annular nozzle is installed together at one end of the two sliders away from the slide grooves. Multiple spray holes are provided on the inner wall of the annular nozzle, and the bottom end of the shell is connected to the annular nozzle through a hose.
[0013] Optionally, the anti-fall mechanism includes two fixing frames installed on the outer wall of the protective cover, and second electric telescopic rods are installed inside the two fixing frames. The telescopic ends of the two second electric telescopic rods are installed with anti-fall blocks, and two through slots are opened inside the protective cover for the anti-fall blocks to move back and forth.
[0014] Optionally, two rectangular frames are installed on the top of the plumb bob, and the adjacent ends of the two anti-fall blocks are located inside the corresponding rectangular frames, and weighing sensors are installed inside the two anti-fall blocks.
[0015] The beneficial effects of the present invention are embodied in:
[0016] 1. In this invention, a spraying mechanism is arranged inside the protective cover, which can automatically spray the rust inhibitor onto the surface of the plumb line for rust prevention, ensuring that the normal use of the plumb line is not affected by rust, and thus ensuring the accuracy of the plumb line in monitoring the deformation of the Bailey frame, so that the plumb line can well meet people's usage needs.
[0017] 2. In this invention, the first steel wire rope has the risk of breaking during the use of the device, causing the plumb line to fall downward during use. With the help of the cooperation between the relevant parts of the anti-fall mechanism inside the protective cover, the two anti-fall blocks can be driven to be inserted into the corresponding rectangular frames. When the first steel wire rope breaks, the plumb line will naturally fall downward, so that the inner bottom surfaces of the two rectangular frames are in contact with the tops of the two anti-fall blocks. With the help of the cooperation between the two anti-fall blocks and the two rectangular frames, the plumb line that falls downward is limited and fixed, so as to achieve the effect of preventing the plumb line from falling and improve the protection effect on the plumb line.
[0018] 3. In the invention, when one of the first steel wire ropes breaks, causing the plumb line to fall and be restricted to the bottom of the protective cover by the corresponding two anti-fall blocks, the plumb line is still in a suspended state. The first winding wheels corresponding to the other two first steel wire ropes are controlled to continue to rotate, driving the other two first steel wire ropes to continue to extend downward, so that the rectangular frames on the top of the two plumb lines can be abutted and matched with the corresponding two anti-fall blocks, and the weight of the protective cover is increased for the other two plumb lines, thereby ensuring that multiple plumb lines and corresponding protective covers can be used together as a structure for monitoring the deformation of the Bailey frame, which is convenient for maintaining the deformation monitoring work of multiple plumb lines at different positions of the Bailey frame, and is beneficial to the overall use of the device.
[0019] 4. In this invention, since the plumb line may cause wear and tear after long-term use, causing changes in its mass, the weight of the plumb line can be automatically weighed and detected with the help of weighing sensors inside the two anti-fall blocks during the use of the plumb line. If the mass of the lead plumb line decreases by ≥5%, the plumb line needs to be replaced to ensure that the plumb line does not affect the deformation monitoring of the Bailey frame.

DETAILED DESCRIPTION
[0032] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.
[0033] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.
[0034] like Figures 1-10As shown, a Bailey frame deformation monitoring device includes a device body 1, the top of the device body 1 is connected and fixed to the Bailey frame by a set connecting mechanism, two storage slots 4 are opened inside the device body 1, and rotating blocks 5 are rotatably installed inside the two storage slots 4. The ends of the two rotating blocks 5 away from the rotating part are connected to the mounting blocks 7 through two first electric telescopic rods 6, and the bottom center position of the device body 1 and the bottom of the two mounting blocks 7 are installed with a box body 8 through a set mounting mechanism. A plumb line 10 is provided at the bottom of the box body 8, and a protective cover 9 for protecting the plumb line 10 is also provided at the bottom of the box body 8. A spraying mechanism for spraying a rust inhibitor to the surface of the plumb line 10 and an anti-falling mechanism for preventing the plumb line 10 from falling are provided inside the protective cover 9. During actual use, two first motors are preset on one side outer wall of the device body 1, and the output ends of the two first motors are respectively connected to the rotating parts of one end of the two rotating blocks 5, thereby driving the two rotating blocks 5 to rotate inside the corresponding storage slots 4, and driving the two first electric telescopic rods 6 and the mounting block 7 to rotate and adjust synchronously.
[0035] As a technical optimization solution of the present invention, the connecting mechanism includes two fixed rods 2, both of which are installed in the center of the top of the device body 1. A groove is opened on the top of each of the two fixed rods 2, and a double-headed screw rod 11 is rotatably installed inside the two grooves. The outer walls of the two double-headed screw rods 11 are threaded with two connecting plates 3. A second motor is preset on the outer wall of one side of the two fixed rods 2, and the output ends of the two second motors are respectively connected to one end of the two double-headed screw rods 11, thereby driving the two double-headed screw rods 11 to rotate inside the corresponding grooves, and driving the two connecting plates 3 to move and adjust in the direction of approaching or moving away from each other.
[0036] As a technical optimization solution of the present invention, the installation mechanism includes two fixed plates 12 installed at the bottom of the device body 1 and the two mounting blocks 7, and limiting plates 14 are slidably installed inside the two fixed plates 12. The outer walls on both sides of the box body 8 are provided with limiting grooves 15 that are compatible with the limiting plates 14.
[0037] As a technical optimization solution of the present invention, the interiors of the two fixing plates 12 are both threadedly installed with screw rods 13, and the adjacent ends of the two screw rods 13 are rotatably connected to their corresponding limit plates 14. After the box body 8 is placed between the two fixing plates 12, it is ensured that the two limit grooves 15 on the outer wall of the box body 8 correspond to the positions of the two limit plates 14. By screwing the two screw rods 13 in sequence, the two limit plates 14 are driven to move in the direction of approaching each other until they enter the corresponding limit grooves 15. This allows the box body 8 between the two fixing plates 12 to be limited and fixed, achieving the effect of quickly installing the box body 8. When the box body 8 needs to be disassembled later, by screwing the two screw rods 13 in opposite directions, the two limit plates 14 can be moved away from each other until they are removed from the corresponding limit grooves 15. The box body 8 can then be removed from between the two fixing plates 12, making it convenient to disassemble and replace the box body 8 and multiple components at its bottom.
[0038] As a technical optimization solution of the present invention, a first winding wheel 22 and two second winding wheels 23 are rotatably installed inside the box body 8. The outer walls of the first winding wheel 22 and the two second winding wheels 23 are respectively wound with the first steel wire rope 17 and the second steel wire rope 18. The end of the first steel wire rope 17 away from the first winding wheel 22 is connected to the plumb line 10, and the ends of the two second steel wire ropes 18 away from the second winding wheels 23 are both connected to the protective cover 9. Three third motors are preset inside the box body 8, and the output ends of the three third motors are respectively connected to the rotating parts of one end of the first winding wheel 22 and the two second winding wheels 23, so as to drive the first winding wheel 22 and the two second winding wheels 23 to rotate inside the box body 8, thereby driving the first steel wire rope 17 and the two second steel wire ropes 18 wound on the outer walls to extend or reel downward.
[0039] As a technical optimization solution of the present invention, a cylindrical cushion 24 is installed in the center of the interior of the protective cover 9. A through hole is opened in the center of the cushion 24, and the first steel rope 17 abuts the inner wall of the through hole. The cushion 24 inside the protective cover 9 can reduce the rigid friction between the protective cover 9 and the first steel rope 17, thereby reducing the impact on the first steel rope 17.
[0040] As a technical optimization solution of the present invention, the spraying mechanism includes a housing 16 mounted on the outer wall of the protective cover 9, the interior of the housing 16 is filled with a rust inhibitor, and a liquid injection port is provided on the top of the housing 16. The rust inhibitor can be injected into the interior of the housing 16 through the liquid injection port for temporary storage pending subsequent use.
[0041] As a technical optimization solution of the present invention, the inner wall of the protective cover 9 is provided with two chutes 27, and sliders 28 are installed inside the two chutes 27. An annular nozzle 29 is installed at one end of the two sliders 28 away from the chutes 27. A plurality of spray holes 31 are provided on the inner wall of the annular nozzle 29. The bottom end of the shell 16 is connected to the annular nozzle 29 via a hose 19. By pre-setting a suction pump inside the shell 16, the suction pump can transport the rust inhibitor stored inside the shell 16 to the inside of the annular nozzle 29 through the hose 19, and spray it outwardly onto the surface of the line bob 10 through the plurality of spray holes 31, thereby achieving the effect of rust prevention on the surface of the line bob 10; linear motors are pre-set inside the two chutes 27, and the two linear motors can drive the two sliders 28 to move up and down inside the corresponding chutes 27, thereby driving the annular nozzle 29 to move up and down inside the protective cover 9, so that the plurality of spray holes 31 on the inner wall of the annular nozzle 29 can evenly spray the rust inhibitor onto the surface of the line bob 10.
[0042] As a technical optimization solution of the present invention, the anti-fall mechanism includes two fixed frames 20 mounted on the outer wall of the protective cover 9. A second electric telescopic rod 21 is mounted inside each fixed frame 20. The telescopic ends of the two second electric telescopic rods 21 are each mounted with an anti-fall block 25. Two through slots are defined within the protective cover 9 for the anti-fall blocks 25 to move back and forth. During the telescopic process, the telescopic ends of the two second electric telescopic rods 21 can drive the two anti-fall blocks 25 to move synchronously within the through slots.
[0043] As a technical optimization solution of the present invention, two rectangular frames 26 are installed on the top of the plumb bob 10. The adjacent ends of the two anti-fall blocks 25 are located inside the corresponding rectangular frames 26, and weighing sensors 30 are installed inside the two anti-fall blocks 25. The two anti-fall blocks 25 can be inserted into the corresponding rectangular frames 26 by means of the control of the corresponding second electric telescopic rods 21. After the first steel wire rope 17 breaks, the plumb bob 10 can be limited by the insertion between the two anti-fall blocks 25 and the rectangular frames 26, preventing the plumb bob 10 from falling downward, thereby achieving the effect of preventing the plumb bob 10 from falling off; the two weighing sensors 30 are both high-precision weighing sensors of the prior art model YZC-1B, which have high precision and stability.
[0044] In the present invention, when the user uses the device, the device as a whole is Figure 10The state shown is that the two rotating blocks 5 drive the corresponding two first electric telescopic rods 6 and the mounting blocks 7 to rotate and be stored inside the corresponding storage slots 4, so that the overall volume of the device is reduced at this time, and the first winding wheel 22 and the second winding wheel 23 inside the two boxes 8 drive the corresponding first steel wire rope 17 and the second steel wire rope 18 to be wound together to the shortest state, driving the corresponding two protective covers 9 and the plumb bob 10 to tightly abut against the outer walls of the boxes 8 close to them, and controlling the telescopic ends of the two second electric telescopic rods 21 arranged outside the two protective covers 9 to extend together, driving the two anti-fall blocks 25 to limit the plumb bob 10 stored inside the protective cover 9 at this time, and cooperating with the protective cover 9 to protect the plumb bob 10, preventing the plumb bob 10 from shaking at will when not in use and in transportation, causing the plumb bob 10 to collide with other components, affecting the subsequent use of the plumb bob 10.
[0045] The staff will Figure 10 After the device shown in the collapsed state is transported to the vicinity of the Bailey rack to be monitored, Figure 1 As shown, the two rotating blocks 5 are then controlled to drive the corresponding two first electric telescopic rods 6 and the mounting block 7 to rotate and extend outward from the inside of the storage slot 4, and then the entire device is placed at the bottom of the Bailey frame to be monitored, ensuring that the entire device is parallel to the Bailey frame, and the two fixed rods 2 are located in the center of the bottom of the Bailey frame. Finally, the two double-headed screws 11 can be controlled to rotate, driving the two connecting plates 3 of its outer wall to move in a direction close to each other, until the two connecting plates 3 are tightly abutted against the outer walls of the Bailey frame on both sides. With the help of the bending parts set at the top of the two connecting plates 3, the two connecting plates 3 can also be tightly abutted against the top of the Bailey frame, and the entire device can be stably installed at the bottom of the Bailey frame and wait for use.
[0046] After the device is installed as a whole at the bottom of the Bailey frame to be monitored, the telescopic ends of the two groups of first electric telescopic rods 6 can be controlled to extend together, driving the two mounting blocks 7 to move and adjust in opposite directions until the two mounting blocks 7 move to the two ends of the bottom of the Bailey frame, so that the plumb bobs 10 located at the bottom of the device body 1 and the bottom of the two mounting blocks 7 can be evenly distributed at the bottom of the Bailey frame, and then the first winding wheels 22 inside the multiple boxes 8 are controlled to rotate together, driving the multiple first steel ropes 17 and the plumb bobs 10 connected to their bottoms to move downward to a height of 1m from the ground, and then a 1.5m long steel pipe is set up next to the multiple plumb bobs 10, and the bottom ends of the multiple steel pipes are driven 0.4m underground, and 200mm long scale paper is pasted on the top of the multiple steel pipes as a monitoring basis. During monitoring, a large triangle is used to press one side against the steel pipe and the other side is aligned with the tip of the plumb bob 10. Lines are drawn on the scale paper and the readings are recorded. The calculated difference is the settlement value of the Bailey frame.
[0047] When the plumb bob 10 is located at the bottom of the Bailey frame and used for a long time, it is necessary to regularly apply a rust inhibitor on the surface of the plumb bob 10 and the first steel wire rope 17 to prevent rust from forming on the surface of the first steel wire rope 17 and the plumb bob 10, which may cause the first steel wire rope 17 to break and the quality of the plumb bob 10 to change. At this time, the two second winding wheels 23 inside the multiple boxes 8 can be controlled to rotate together, driving the multiple second steel wire ropes 18 and the protective covers 9 connected to the bottom to move downward together, and ensuring that the multiple protective covers 9 are completely covered on the corresponding plumb bob 10 surfaces, and controlling the preset suction pump inside the shell 16 to start, sucking the rust inhibitor inside the shell 16 and transporting it to the inside of the annular nozzle 29, and spraying it outward to the surface of the plumb bob 10 with the help of the multiple spray holes 31, and with the help of the two sliders 28 to move up and down inside the slide groove 27, driving the multiple spray holes 31 to evenly spray the rust inhibitor on the surface of the plumb bob 10, performing relevant rust prevention treatment on the outer wall of the plumb bob 10, and ensuring that the normal use of the plumb bob 10 is not affected by rust;
[0048] When the two sliders 28 drive the annular nozzle 29 to move upward to the inner top of the protective cover 9, the rust inhibitor sprayed outward from the multiple nozzles 31 can be absorbed by the soft pad 24 and temporarily stored. After the rust prevention treatment of the outer wall of the plumb bob 10, the two second winding wheels 23 inside the multiple boxes 8 can be controlled to reverse, driving the multiple second steel ropes 18 to be wound, thereby driving the multiple protective covers 9 to move slowly above the plumb bob 10. As the multiple protective covers 9 move, the multiple soft pads 24 can automatically apply the rust inhibitor absorbed inside to the surface of the first steel rope 17, so as to achieve the effect of assisting the rust prevention treatment of the surface of the first steel rope 17, avoiding the waste caused by directly using multiple nozzles 31 to spray a large amount of rust inhibitor on the surface of the first steel rope 17, and ensuring that the normal use of the first steel rope 17 is not affected by rust.
[0049] At the same time, if the rust preventive stored inside the shell 16 is a water-based rust preventive, in order to facilitate its subsequent smooth outward spraying with the help of the annular nozzle 29, it is necessary to inject an appropriate amount of water into the shell 16 after injecting the rust preventive into the shell 16 to dilute the rust preventive and ensure that the viscosity of the rust preventive is reduced for easy spraying. Then, the two second winding wheels 23 corresponding to the multiple protective covers 9 can be controlled to rotate forward and backward continuously, driving the multiple protective covers 9 and the shell 16 installed on the outer wall to move up and down repeatedly above the bobbin 10, so that the rust preventive inside the shell 16 can be evenly mixed with water, which is convenient for the subsequent use of the rust preventive.
[0050] Moreover, when the device is used in cold northern regions, the above-mentioned step of spraying the rust preventive agent on the outer wall of the line sinker 10 by means of the spraying mechanism to achieve the rust preventive effect can be repeated. At this time, multiple protective covers 9 are all provided on the surface of the corresponding line sinkers 10, so that the multiple protective covers 9 can shield and protect the multiple line sinkers 10, and prevent snow or ice from accumulating on the surface of the line sinkers 10 in the external environment, causing the line sinkers 10 to become stuck and unable to be used normally.
[0051] In addition, when the device is used in a construction site with a large amount of dust, dust will adhere to the surface of the first steel wire rope 17. At this time, the above steps of using the protective cover 9 to move up and down to drive the soft pad 24 to rub against the outer wall of the first steel wire rope 17 to apply the rust inhibitor can be repeated to automatically clean the dust attached to the outer wall of the first steel wire rope 17, thereby reducing the problem of dust adhering to the surface of the first steel wire rope 17 and causing the friction force of the first steel wire rope 17 to change, thereby improving the applicability of the protective cover 10 in actual processes.
[0052] For example, when the device is in use, it is necessary to control the hanging height of the plumb line 9 to exceed 2m, or when the plumb line 10 is in use, large vehicles around it are constantly moving back and forth, causing the plumb line 10 at the bottom of the first wire rope 17 to continuously swing after being vibrated, causing the first wire rope 17 and the box 8 to continuously wear. At this time, the first wire rope 17 has a risk of breaking, causing the plumb line 10 to fall downward during use. Figure 6 As shown, the protective cover 9 can be controlled to move downward to a suitable position on the top of the plumb bob 10, ensuring that the two anti-falling blocks 25 are flush with the two rectangular frames 26 on the top of the plumb bob 10, and then the telescopic ends of the two second electric telescopic rods 21 are controlled to extend together, driving the two anti-falling blocks 25 to be inserted into the corresponding rectangular frames 26. Since the volume of the two anti-falling blocks 25 is smaller than the space inside the rectangular frames 26, after the two anti-falling blocks 25 are inserted into the rectangular frames 26, they will not abut against the inner wall of the rectangular frames 26, thereby not affecting the normal use of the plumb bob 10;
[0053] When the first steel wire rope 17 breaks, the plumb line 10 will naturally fall downward, so that the inner bottom surfaces of the two rectangular frames 26 abut against the tops of the two anti-falling blocks 25. With the cooperation of the two anti-falling blocks 25 and the two rectangular frames 26, the plumb line 10 falling downward is limited and fixed, so as to achieve the effect of preventing the plumb line 10 from falling and improve the protection effect of the plumb line 10.
[0054] When one of the first steel wire ropes 17 breaks, causing the plumb bob 10 to fall and be restricted under the protective cover 9 by the corresponding two anti-fall blocks 25, the plumb bob 10 is still in a suspended state. In order to ensure that the deformation monitoring work of multiple plumb bobs 10 at different positions of the Bailey frame is not affected and to ensure that the weight of multiple plumb bobs 10 is the same, the first winding wheels 22 corresponding to the other two first steel wire ropes 17 can be controlled to continue to rotate, driving the other two first steel wire ropes 17 to continue to extend downward, so that the rectangular frames 26 on the top of the two plumb bobs 10 can be abutted and matched with the corresponding two anti-fall blocks 25, and the weight of the protective cover 9 is increased for the other two plumb bobs 10, thereby ensuring that multiple plumb bobs 10 can be used together with the corresponding protective cover 9 as a structure for monitoring the deformation of the Bailey frame, which is convenient for maintaining the deformation monitoring work of multiple plumb bobs 10 at different positions of the Bailey frame, and is beneficial to the overall use of the device.
[0055] Since the line sinker 10 may be worn out after long-term use, its quality may change. Figure 6 As shown, after controlling the protective covers 9 corresponding to the multiple plumb bobs 10 to move downward to the specified position, the telescopic ends of the multiple second electric telescopic rods 21 are controlled to extend, driving the multiple anti-fall blocks 25 to be inserted into the corresponding rectangular frames 26, and then the two second winding wheels 23 inside the multiple boxes 8 can be controlled to reel in the second steel rope 18, driving the multiple protective covers 9 to move upward together. At this time, as the multiple protective covers 9 move upward, the corresponding two anti-fall blocks 25 can be driven to pull the plumb bobs 10 below upward, so that the weighing sensors 30 inside the two anti-fall blocks 25 automatically weigh and detect the weight of the plumb bob 10. If the mass of the lead sinker is reduced by ≥5%, the plumb bob 10 needs to be replaced to ensure that the plumb bob 10 is not affected by the deformation monitoring work of the Bailey frame.
[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
