For example, gantry cranes, also known as gantry cranes, are actually used in some gantries. Due to the limitations of the model and actual needs when lifting materials, there are often some overload lifting needs, and auxiliary load-bearing devices are required to reduce the load on part of the gantry support legs. However, due to the limited construction environment, the existing auxiliary load-bearing devices cannot flexibly adjust the distance between the load-bearing operation point and the gantry, making its auxiliary function unusable or limited in effect, and unable to meet construction requirements.

[0047] Example 1

[0048] See also Figure 1-Figure 5 The present embodiment provides a lateral lifting mechanism for assisting load-bearing, including a load-bearing body, which has a load-bearing portion 11 for interlocking with an external platform. The load-bearing body is used to assist in bearing the weight of the lifted object, and the load-bearing portion 11 is arranged in the inner cavity of the load-bearing body, and is used to connect and fix with an external platform, such as a load-bearing guide rail, a load-bearing square column, etc. In the present embodiment, a snap-on snap-on connection method or a nested movable snap-on connection can be adopted, the purpose of which is to avoid displacement of the load-bearing body when it is subjected to force. The lateral lifting mechanism also includes a telescopic cylinder 2, one end of which is hinged to the load-bearing portion 11, and the other end is fixedly connected to a connecting platform 3. It should be noted that the telescopic cylinder 2 can be in the form of a cylinder, an oil cylinder or a telescopic electric assembly, and can also be hinged or connected at a fixed angle. Since the present embodiment acts on the lifting and auxiliary load-bearing of a large-weight base lift object, the telescopic cylinder 2 in the present embodiment is preferably a large-tonnage electric hydraulic cylinder commonly seen on the market.

[0049] The connecting platform 3 is mainly used to achieve a stable connection between the lateral lifting mechanism and the lifting object, especially when it is applied to objects with a large base tonnage. It can be made of high-strength steel or cast iron to ensure good connection strength. The first telescopic member 31 and the second telescopic member 32 are respectively arranged on the opposite sides of the connecting platform 3. The opposite sides here mainly refer to the two sides located in different directions of the connecting platform 3, which can be different left and right sides and / or different upper and lower sides. In this embodiment, the form of left and right and upper and lower sides is shown. Specifically, the first telescopic member 31 and the second telescopic member 32 are respectively arranged along the tangent direction of the two opposite sides of the connecting platform 3. The telescopic direction of the first telescopic member 31 and the second telescopic member 32 is consistent with the telescopic direction of the telescopic cylinder 2. The telescopic direction here mainly refers to the three being able to extend or retract in the same direction, such as one of them extending and the other two retracting or both extending and the other retracting. It is not necessary for the three to extend or retract synchronously. In this embodiment, the connecting platform 3 has a disc portion with a circular cross section, the first telescopic member 31 and the second telescopic member 32 and their telescopic directions are arranged along the tangent direction of the disc portion, and the first telescopic member 31 and the second telescopic member 32 extend in opposite directions.

[0050] In the field of construction, for example, gantry is mostly used for lifting and transporting building materials. In actual use, some gantries are limited by the model and actual needs when lifting materials, and often there will be some overload lifting needs, which requires auxiliary load-bearing devices to reduce the load of some gantry support legs. However, due to the limited construction environment, the existing auxiliary load-bearing device cannot flexibly adjust the distance between its load-bearing operation point and the gantry, so that its auxiliary function cannot be used or the use effect is limited, and it cannot meet the construction requirements. In this embodiment, the lifting and auxiliary load-bearing effects of the gantry can be achieved through the above-mentioned design. Furthermore, in order to better adjust the distance between each other and ensure the auxiliary effect, in this embodiment, the connecting platform 3 adopts a disc portion with a circular cross-section, and the first telescopic member 31 and the second telescopic member 32 are respectively arranged at the two ends of any diameter of the connecting platform 3, and the telescopic direction of the first telescopic member 31 and the second telescopic member 32 are arranged along the tangent direction of the disc portion, and the extension direction of the first telescopic member 31 and the second telescopic member 32 is opposite. In this way, the angles of force applied to the first telescopic member 31 and the second telescopic member 32 are parallel in the same plane when the gantry and the load-bearing body are respectively subjected to force, which can avoid the undesirable consequences of local force being unsustainable or the stable structure being destroyed. Of course, this embodiment shows that the disc portion is in the form of a cylinder, and in other embodiments, it can also be a cylinder with other cross-sectional shapes (triangle, square or polygon). The use of the cylindrical form allows the disc portion and the telescopic members arranged along its tangent direction to have better connection strength and connection stability during the lateral lifting process, avoiding the situation of shear damage or load-bearing deformation.

[0051] Similarly, the first telescopic member 31 and the second telescopic member 32 can be in the form of a cylinder, an oil cylinder or a telescopic electric assembly. Specifically in this embodiment, the first telescopic member 31 and the second telescopic member 32 mainly adopt hydraulic oil cylinders. The first telescopic member 31 and the second telescopic member 32 include hydraulic rods arranged on both sides of the connecting platform 3, and the two sides of the geometric center of the connecting platform 3 are connected to the cylinder barrel. In order to better achieve the stability of the connection, the telescopic end of the first telescopic member 31 has a first connecting portion 311 hinged to the lifting object, and the telescopic end of the second telescopic member 32 has a second connecting portion 321 hinged to the load-bearing body. At least the connecting portion is made of the above-mentioned high-strength steel or cast iron, and can be stably connected to the outside through a hinge of the same material. In addition, the second connecting portion 321 is slidably connected to the load-bearing body, that is, a sliding hinge is realized with the load-bearing body through a hinge, and a limiter for limiting the sliding of the second connecting portion 321 is provided on the load-bearing body. The sliding of the second connecting part 321 is used to coordinate the change of the telescopic degree of the first telescopic member 31 and the second telescopic member 32, and timely adjust the force direction of the load-bearing body to avoid the change of the center of gravity of the load-bearing body and the destruction of the load-bearing system. The whole movement process of sliding to adjust the relative position is as follows: After the present embodiment is hinged with the lifting object, when it is displaced, for example, when it is far away from the lifting object, the integrity of the connection is maintained by the extension of the first telescopic member 31 and the second telescopic member 32. As the distance becomes longer, the lever arm where the first telescopic member 31 is located also needs to be increased. When the connecting platform 3 rotates a certain angle to maintain the connection relationship between the present embodiment and the lifting object, the slider 323 is driven to slide to the side away from the lifting object until the edge of the top of the load-bearing body reaches the farthest load-bearing distance.

[0052] See also Figure 1 In this embodiment, when the lifting object is operated, the telescopic directions of the telescopic cylinder 2, the first telescopic member 31 and the second telescopic member 32 remain roughly parallel, that is, the lifting of the lifting object or the auxiliary load-bearing function can be completed. Before the operation, even if the horizontal distance between the load-bearing body and the lifting object changes, the force application directions of the three can be kept parallel within a certain angle through the telescopic movement of the first telescopic member 31 and the second telescopic member 32, and the rotation of the connecting platform 3 and the telescopic cylinder 2, so as to achieve a good and stable lifting effect. At the same time, since the connecting platform 3 is set in a disc shape, compared with a rectangular or other shape, the first telescopic member 31 and the second telescopic member 32 on the opposite side can respectively obtain a part of the auxiliary load-bearing from the connecting platform 3 in its tangential direction, and can also be partially unloaded by the angle at which the first telescopic rod and the second telescopic rod are parallel to each other through the hinged rotation of the connecting platform 3 and the telescopic oil cylinder, thereby reducing the local pressure of the lifting object on this embodiment and making the load have better stability.

[0053] Through the above technical solution, for example, when the lifting object is a gantry, the purpose of lifting or assisting the load on the gantry by using the telescopic cylinder 2 is achieved, and the distance between the load-bearing body and the gantry can be adjusted by the rotation and sliding cooperation of the connecting platform 3 and the second connecting part 321, and the connection between the connecting platform 3, the first telescopic rod and the second telescopic rod is used to ensure that even if it is relatively far away from the gantry, the present embodiment can still have a good auxiliary load effect. Therefore, the cooperation between the present embodiment and the gantry can be applied to more construction environments and meet more construction needs. It should be noted that there is an angle α between the sliding direction of the second connecting part 321 and the axial direction of the telescopic cylinder 2, the purpose is to make the sliding direction of the second connecting part 321 and the axial direction of the telescopic cylinder 2 not on the same straight line, so as to cope with most construction scenes where the lifting direction is inconsistent with the distance adjustment direction, especially to distinguish it from the vertical lifting scene (considering that the gantry needs to move along the track, and the vertical lifting is not applicable to the gantry, that is, it is achieved by side lifting). Among them, the sliding direction of the second connection part 321 is the horizontal direction, and the range of the angle α is 45-90°, so that the lifting movement of a large-tonnage lifting object can be realized, and the distance adjustment in the horizontal direction can be realized, especially considering the stability and safety of the overall movement. For example, when the sliding direction of the second connection part 321 is the horizontal direction, the horizontal distance adjustment can be realized, and the range of the angle α is 45-90°, which can ensure a better supporting effect within the range of the diagonal support.

[0054] In order to achieve a good distance adjustment function and effect, a slide rail 322 is provided at the top of the load-bearing body in this embodiment, and a slider 323 is slidably provided on the slide rail 322. The second connection part 321 is hinged to the slider 323, and the sliding direction of the second connection part 321 is horizontal. The purpose is to concentrate the force points of the load-bearing body at the top, which will not be interfered by external movement, especially compared with the side setting, which is prone to insufficient support strength or easy shearing. At the same time, the weight of the body and the angle of force can achieve a better load-bearing effect without tipping or displacement, thereby ensuring stability during operation. Please refer again Figure 1 and Figure 3, after the distance adjustment is completed, in order to prevent the slider 323 from moving and causing it to be unable to be lifted, the limiting member in this embodiment is a "C"-shaped member made of a hard metal material. Its purpose is to be arranged at both ends of the slider 323 and lock at both ends of the slider 323 on the slide rail 322 after the connection between the load-bearing main body and the lifted object is completed, so as to limit the slider 323 and ensure that the force-bearing fulcrum will not change. Specifically, the above-mentioned limiting member includes a first limiting body 71 and a second limiting body 72. The first limiting body 71 and the second limiting body 72 are symmetrically arranged on both sides of the slide rail 322 respectively. A locking member 73 for locking each other is also arranged between any two symmetrical limiting members. The locking member 73 can be a bolt, an expansion screw or a bolt pin, etc. The specific style and model are not limited in this embodiment, and any part that can ensure that no relative movement occurs between any two limiting members can be used.

[0055] The lateral lifting mechanism for auxiliary load provided in this embodiment can not only achieve the above-mentioned lifting function, but also further achieve a supporting function, especially in ensuring the placement stability of a large-tonnage lifted object after lifting. For example, when a gantry crane is operating, in order to prevent the driving wheel and the driven wheel from shifting on the guide rail, wedges are often manually inserted on both sides of the wheels for limiting during operation. However, since the wedges rely only on friction to limit the lifting of the gantry crane, when the wind is strong or the center of gravity is unbalanced during lifting, the swing of the lifted material may cause the wedges to break open and trigger a safety accident. Furthermore, in addition to being able to adjust the distance before the gantry crane operates to adapt to more construction environments, this embodiment can also limit the driving wheel of the gantry crane during operation to prevent displacement and affect the lifting effect. Please refer to again Figure 4-Figure 5, and also includes a supporting component 4 for supporting the lifted object, the supporting component 4 includes a supporting plate 41, a power box 43 and a supporting pad 42, the supporting plate 41 and the load-bearing body are hinged through a rotating wheel 44, that is, the supporting plate 41 and the rotating wheel 44 share a rotating shaft, and the rotating wheel 44 is configured with a driving force. Specifically, the rotating wheel 44 adopts a rotating motor in this embodiment, which is coaxially arranged with the hinge point of the support plate 41, wherein a transmission gear 21 that can rotate synchronously with the telescopic cylinder body 2 is provided at the hinge of the telescopic cylinder body 2 (that is, the transmission gear 21 and the telescopic cylinder body 2 are connected to the load-bearing body through a rotating shaft), and the transmission gear 21 and the rotating wheel 44 can mesh with each other, thereby realizing the transmission function of the two. The power box 43 is arranged at the other end of the support plate 41 and is connected to the rotating wheel 44 in a transmission manner. The supporting pad 42 is slidably arranged on the power box 43 and can extend toward the side of the lifting object relative to the power box 43 to support the lifting object. The power box 43 is used to drive the supporting pad 42 to extend or retract relative to the power box 43. In this way, before the gantry is operated, the gantry is properly lifted by this embodiment. When the driving wheel or the driven wheel of the gantry leaves the guide rail, the supporting pad 42 is extended into both sides of the wheel to replace the wedge to complete the position limiting of the wheel. This can not only stop the dangerous behavior of manually inserting wedges into the guide rail, but also can further limit the position through the support plate 41 of this embodiment, thereby further improving the safety of the gantry during operation.

[0056] Back to the present embodiment, the support plate 41 also adopts a rod / plate type semi-enclosed structure made of hard metal material, which can be sleeved on the coaxial hinge point between the support plate 41 and the rotating wheel 44, and its hinge connection with the load-bearing body can adapt to the gantry with different tire heights. The supporting pad 42 includes a main board 421 and a pad body 81 slidably mounted on one end of the main board 421. The main board 421 is provided with a transverse gear 82 on the side close to the pad body 81. The pad body 81 and the main board 421 are connected to each other through the transverse gear 82 so that the pad body 81 can rotate with the transverse gear 82 as the base point. Specifically, through the rotation of the transverse gear 82, the pad body 81 can rotate and fall under the tire after the tire is raised to fit the diameter of the tire. The power box 43 and the supporting pad 42 are symmetrically arranged on both sides of the load-bearing main body shell, and the pad body 81 is arranged on an arc-shaped side opposite to the tire, which is similar to the trend of the tire and can just fit the local line shape of the tire, and the outer surface can have concave and convex patterns to increase the friction between the tire and the pad body 81. In this way, when the tire falls on the guide rail, the pad body 81 of this embodiment is also subject to the friction force from the gantry, and through the left and right limit connection of the support plate 41, the influence of the shaking of the gantry during the lifting process on the stability of the original wedge can be minimized to the greatest extent, reducing the probability of safety accidents.

[0057] In addition, during the actual research and development process, the inventor found that controlling the movement of the telescopic cylinder 2 and the supporting assembly 4 by the hydraulic control system alone is prone to problems of poor coordination and the need for sequential control. Therefore, in the improved design, the control of the telescopic cylinder 2 and the control of the supporting assembly 4 are integrated together after the calculation of the size and parameters, which achieves the purpose of synchronous movement of the two on the one hand, and the purpose of improving construction efficiency and reducing the coordination cost of the previous and next processes on the other hand. In addition, in order to prevent the supporting pad 42 from being relatively telescopic when adjusting the distance before the operation, the coordination of the support plate 41 and the power box 43 in this embodiment can also perform a certain degree of clutch action relative to the telescopic cylinder 2, that is, when adjusting the distance before the operation, the movement of the telescopic cylinder 2 will not drive the power box 43 to transmit the support pad 42.

[0058] In order to achieve the above-mentioned synchronous transmission effect, the power box 43 includes a box body 431. The model and style of the box body 431 are not limited in this embodiment, and can be a container made of any hard material such as steel, alloy, iron, etc. The box body 431 is provided with a first gear set 51, a second gear set 52 and a third gear set 53. The same group of gears between any of the first gear set 51, the second gear set 52 and the third gear set 53 are coaxially connected to each other. The box body 431 is provided with a slide groove 63 on one side close to the rotating wheel 44. The slide groove 63 is arranged in the box body 431 from top to bottom in an arc shape that can cooperate with the first gear set 51, and its extension direction and slot shape can just match the first gear set 51. The first gear set 51 is connected to the rotating wheel 44 through the chain 434, and the first gear set 51 can slide in the slide groove 63 and mesh with the second gear set 52. When the rotating wheel 44 rotates under the meshing drive of the transmission gear 21, the first gear set 51 can be driven by the chain 434 to slide in the slide groove 63, so as to mesh with the second gear set 52. The power box 43 also includes a telescopic support leg 432, one end of which can be slidably extended into the box body 431, and the first rack 61 meshing with the second gear set 52 is provided at the end, and the other end of the telescopic support leg 432 has an elastic support leg 433 mutually supported with the foundation surface. The design of the telescopic support leg 432 is mainly considered to ensure the good support stability of the supporting assembly 4 when it is used to support the lifting object. Through the function of the telescopic support leg 432, a higher support strength and effect can be achieved through mutual support with the foundation surface. The power box 43 also includes a telescopic plate 532, one end of which can be slidably extended into the box body 431, and the second rack 62 meshing with the third gear set 53 is provided at the end, and the other end faces the lifting object and is connected to the supporting pad 42. Among them, since the gantry frame also needs to be hoisted with heavy objects in actual use, in order to better maintain the stability of the system and a good construction effect, as mentioned above, the telescopic support leg 432 can not only provide a certain load-bearing auxiliary effect when the load-bearing body operates the gantry frame, but also act as an intermediate piece to play a role of linkage or transmission. When the lifting mechanism of this embodiment is operating, the third gear set 53 is connected to the second gear set 52 in a transmission connection, so that when the second gear set 52 drives the telescopic support leg 432 to slide, in addition to the elastic support leg extending to the ground to assist in bearing again, it can also drive the third gear set 53 to transmit, so that the supporting pad 42 can be extended or retracted relative to the box body 431 through the telescopic plate 532.

[0059] Considering that the support plate 41 and the power box 43 can cooperate with each other to a certain extent to perform a clutch action relative to the telescopic cylinder 2, for details, please refer to Figure 5The first gear set 51 includes a first middle gear 511 and first side gears 512 arranged on both sides of the first middle gear 511. A chain 434 is connected to at least one side of the first side gear 512 (if a double chain 434 transmission is adopted, the first side gears 512 on both sides can be used to be connected to each other with the chain 434 for transmission). The chain 434 is connected to the rotating wheel 44 in the semi-enclosed cavity of the support plate 41. Specifically, an opening is provided at the upper end of the semi-enclosed structure of the support plate 41, and the opening is used to enable the chain 434 to mesh with the transmission gear 21 for transmission. Before reaching the working position, the chain 434 can be driven away from the transmission gear 21 by the rotation of the support plate 41, so that the displacement and rotation of the telescopic rod body will not affect the gear transmission inside the power box 43; after reaching the working position (the working position here refers to the horizontal working position where the telescopic cylinder 2 changes its position due to the second connecting part 321 changing its sliding position), the driving wheel 44 drives the rotation of the support plate 41, so that the chain 434 is meshed with the transmission gear 21, so that when the telescopic cylinder 2 rotates and lifts, the first side gear 512 can be driven to rotate by the chain 434. The second gear set 52 includes a second middle gear 521 and a second side gear 522 arranged on both sides of the second middle gear 521, one side of the second middle gear 521 is meshed with the corresponding side, the first middle gear 511, and the other end is meshed with the first rack 61, so that when the second middle gear 521 rotates, the telescopic leg 432 will also be extended and retracted up and down in the extension direction of the first rack 61 to achieve auxiliary load-bearing. The third gear set 53 includes two third side gears 531, which mesh with the second side gears 522 on the corresponding sides, and the third side gear 531 on at least one side also meshes with the second rack 62. When the third gear set 53 is transmitted, the supporting pad 42 is extended or retracted relative to the box body 431 through the telescopic plate 532. The model of the gear is not limited in this embodiment and can be set according to actual needs. Through the specific design of the above gear set, not only the function of synchronous movement is realized, but also the support strength is good. In the actual design of the inventor, not only the non-interference of the movement positions is considered, but also the design and production costs of the power box 43 are minimized under the premise of reliable transmission.

[0060] In order to make this embodiment adaptable to gantry rails of different heights, the supporting pad 42 also includes an adjusting device 422, the adjusting device 422 includes a fixed end 4221 and a movable end 4222, the movable end 4222 is vertically arranged and embedded in the fixed end 4221, and the movable end 4222 can move relative to the fixed end 4221 along its extension direction; the fixed end 4221 is fixedly connected to the telescopic plate 532, and one side of the movable end 4222 is connected to the supporting pad 42, the purpose is to adjust the height of the supporting pad 42, and a common telescopic motor on the market can be used to achieve this function, which will not be repeated here. In addition, in order to better liberate manpower and reduce the danger of operators, the supporting pad 42 includes a main board 421 and a pad body 81 slidably mounted on one end of the main board 421, a remote control module is arranged in the main board 421, and a transverse gear 82 connected to the remote control module, and the pad body 81 can be driven by the transverse gear 82 to move closer to or farther from the main board 421. After the supporting pad 42 is extended, the remote control transverse gear 82 can make the pad body 81 fit the wheel, and there is no need to manually approach to remove the wedge or to check the positioning of the wedge. At the same time, in order to better ensure the safety of the operation, the first connecting part 311 of this embodiment is hinged to the crossbeam between the gantry legs. When operating, this embodiment should be provided with at least one on each side of the gantry support leg to prevent the gantry from tilting on one side. It should be noted that the above control can be achieved through a conventional PLC program, and this application will not elaborate on it here.

[0061] Therefore, in a specific construction operation, when the gantry needs to be lifted, the second connection part 321 of the present embodiment is first hinged to the gantry, and then, according to the on-site working environment, the support plate 41 is first driven by the rotating wheel 44 to rotate at a certain angle toward the ground, so that the support plate 41 is separated from the transmission gear 21, and then the distance between the lifting mechanism and the gantry and the height between the supporting pad 42 and the gantry load-bearing guide rail are adjusted. After the adjustment is completed, the first limit body 71 and the second limit body 72 are locked at the top of the load-bearing body, and the rotating wheel 44 is adjusted so that the chain 434 on the support plate 41 is meshed with the transmission gear 21. Thereafter, through the extension and contraction of the telescopic cylinder 2, with the cooperation of the connecting platform 3 and the power box 43, after the gantry is lifted, it extends into the supporting pad 42 to complete the clamping of the gantry driving wheel.

[0062] Through the above technical solutions, this embodiment can adapt to the lifting and auxiliary load-bearing requirements of lifting objects in more engineering environments, especially for some scenes such as gantry support. The distance between this embodiment and the gantry can be flexibly adjusted, especially after the gantry is lifted to a proper amount, the support assembly 4 of this embodiment can be used to automatically extend into the support pad 42, and no manual extension or clamping of wedges is required, which greatly improves the safety of engineering projects.

[0063] Example 2

[0064] This embodiment also provides a gantry, including at least two lateral lifting mechanisms for auxiliary loads as described in Example 1, and may also include 3, 4, 5 or even more, especially including an even number, to achieve stable and symmetrical lifting. Because the symmetrical setting can ensure that the combined force direction of the gantry support legs 91 is upward to achieve the lifting effect, otherwise the lifting on one side may cause excessive horizontal force component to cause rollover. It should be noted that the lateral lifting mechanism for auxiliary loads in Example 1 here refers to the technical component unit of the smallest lateral lifting mechanism for auxiliary loads in Example 1 that can achieve "good lifting and supporting auxiliary effects, and can flexibly adjust the horizontal distance between the lifted object".

[0065] In addition, the gantry frame further comprises a gantry frame body 9, and the bottoms of the two supporting legs 91 of the gantry frame body 9 are provided with driving wheels for running on the track;

[0066] The two auxiliary load-bearing lateral lifting mechanisms are symmetrically arranged at the two supporting legs 91 of the gantry body 9 with respect to the gantry body 9, and are hinged to the supporting legs 91 through the first connecting portion 311; and

[0067] The two supporting pads 42 are used to support the driving wheels on the corresponding sides. They can just fit the local line shape of the tire. And the outer surface has concave and convex patterns to increase the friction between the tire and the pad body 81. In this way, when the tire falls on the guide rail, the pad body 81 in this embodiment 1 is also subject to the friction brought by the gravity of the gantry body 9, and through the left and right limit connection of the support plate 41, the influence of the shaking of the gantry during the lifting process on the stability of the original wedge can be minimized to the greatest extent, reducing the probability of safety accidents.

[0068] The lateral lifting device provided in this embodiment can lift the gantry body 9 or assist in bearing the load (for details, please refer to the corresponding description in Example 1), and can flexibly adjust the distance between the two while ensuring the load-bearing effect. It has a wider range of use and is more adaptable to different construction environments. Through the articulation of the connecting platform 3 and the sliding cooperation of the second connecting part 321, the connection and force application effect of the connecting platform 3 have a long service life and can be reused. In particular, the force application direction of the first telescopic member 31, the second telescopic member 32 and the telescopic oil cylinder can ensure that they can play a good auxiliary role in the lifting process of the gantry body 9 over long distances or long distances. In this embodiment, the cooperation of the supporting assembly 4 can replace manual dangerous operations, which can not only limit the gantry body 9 more stably, but also reduce the personnel risks during the construction process.

[0069] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
