Description

Technical Field

[0001] The present invention belongs to the technical field of cable saddle anchoring, and more specifically, relates to a high-precision grid plate leveling device for anchoring a cable saddle and an application method thereof. Background Art

[0002] The cable saddle is an indispensable key component in bridge structures such as suspension bridges and cable-stayed bridges, and is responsible for dispersing the force of the main cable or the cable. It is usually carefully installed on the main tower or pier, and its core mission is to cleverly disperse the concentrated force borne by the main cable or the cable to various structural parts of the bridge, so as to ensure the structural safety and stability of the entire bridge. In the design of the cable saddle, many factors such as the uniform distribution of the cable force, anti-slip ability, and long-term durability must be comprehensively considered to ensure that it can function reliably throughout the life cycle of the bridge. In the installation process of the cable saddle, the grid, as an important part of the cable saddle support structure, plays a key role in providing a relatively flat support surface for the cable saddle. Therefore, the leveling of the grid becomes a crucial step in the installation process of the cable saddle. Only by ensuring that the contact surface between the grid and the cable saddle is flat and correct can the uniformity of the cable force during the transmission process be guaranteed, thereby maintaining the stability and safety of the bridge structure.

[0003] In the prior art, a Chinese patent with the announcement number CN117071454A discloses a combined cable saddle jacking base and a jacking construction method based on the base. The jacking base includes a base body, which has a reaction frame at the bottom of the side span end, a jacking stopper at the top, and a side span side avoidance groove formed inwardly along the length direction at the center of the width direction; the middle span end of the base body has a middle span side avoidance groove formed inwardly along the length direction at the center of the width direction; the base body at the middle span side avoidance groove is connected with at least one group of base filling sections capable of filling the middle span side avoidance groove in a split assembly structure; the base filling sections cooperate with the jacking stroke of the cable saddle to fill the middle span side avoidance groove of the base body.

[0004] Although the above patent effectively solves the technical problem of position interference between the main cable on the mid-span side and the jacking base caused by excessive jacking pre-bias while meeting the requirements of jacking construction, and ensures the stability of the saddle during jacking construction through multiple grid components, it still cannot solve some problems existing in the prior art, such as (1) the leveling operation of the grid plate is complicated and difficult to construct; (2) jacks are often used in the leveling operation of traditional grid plates, but the adjustment accuracy of the jacks is usually low, making it difficult to achieve high-precision leveling requirements, further increasing the difficulty of leveling construction, and may cause the flatness of the grid to fail to meet the design standards.

In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] Example 1

[0043] like Figures 1 to 4 As shown, Embodiment 1 of the present invention provides a high-precision grid plate leveling device for anchoring cable saddles, comprising: a support unit and a leveling unit; the support unit comprises a lower support component connected to the foundation concrete layer 1 and an upper support component whose upper surface contacts the grid plate 2, and the lower support component is arranged directly below the hole of the grid plate 2; the leveling unit is arranged between the lower support component and the upper support component. During use, the lower support component is connected to the foundation concrete layer 1 to ensure the stability of the overall structure, and the upper support component stably supports and disperses the load of the grid plate 2 to avoid the problem of excessive local stress caused by load concentration; secondly, the height of the upper support component is finely adjusted by the multiple wedge leveling components of the leveling unit arranged between the lower support component and the upper support component. The leveling operation is simple, and the grid plate 2 can be fine-tuned and leveled without complicated tools or equipment. In addition, the structure has high adjustment accuracy, which can ensure that the installation accuracy of the grid plate 2 meets the design requirements.

[0044] Specifically, Figure 1 system Figure 3As shown, the support unit includes the lower support component connected to the foundation concrete layer 1 and the upper support component whose upper surface contacts the grid plate 2, and the lower support component is arranged directly below the holes of the grid plate 2 to stably support the grid plate 2 and distribute the load. The lower support component includes: embedded parts 3 and rigid pads 4; the embedded parts 3 are arranged in the foundation concrete layer 1 and directly below the holes of the grid plate 2; the rigid pads 4 are arranged in the middle of the upper surface of the embedded parts 3, and the upper end thereof is connected to the leveling unit; the upper support component includes a support beam 5, the upper surface of the support beam 5 contacts the grid plate 2 and is connected to the leveling unit arranged below it. During use, by presetting the embedded parts 3 in the base concrete layer 1 corresponding to the holes of the grating plate 2, and arranging the rigid pads 4 and multiple support parts of the support beams 5 thereon, the overall structural stability can be effectively enhanced, and it is helpful to adjust the overall height of the leveling device, thereby reducing the leveling operation time; secondly, by arranging the leveling unit between the support beam 5 and the rigid pad 4, the load of the grating plate 2 can be supported and dispersed by the support beam 5, and the height of the support beam 5 can be fine-tuned by the leveling unit, thereby leveling the grating plate 2, which can effectively improve the leveling accuracy.

[0045] Preferably, the upper surface of the embedded part 3 is flush with the upper surface of the foundation concrete layer 1 to facilitate stable connection of the rigid pad 4.

[0046] Preferably, the embedded part 3 includes a square plate connected to the rigid pad 4 and a plurality of embedded rods arranged at the bottom end of the square plate, and the ends of the embedded rods are bent to further improve the connection strength between the embedded part 3 and the foundation concrete layer 1 to ensure the stability of the leveling device.

[0047] Preferably, the embedded part 3 and the rigid pad 4 are fixedly connected by welding to provide higher structural strength, withstand greater loads, and significantly improve construction efficiency for the installation of multiple leveling devices.

[0048] Preferably, the embedded parts 3, the rigid pads 4 and the support beams 5 are mainly made of high-strength rust-proof metal materials, which include but are not limited to: chromium-containing stainless steel, galvanized steel, and high-strength alloy steel. It should be noted that in other embodiments, other types of metal materials may also be used, which are not specifically limited here, but these solutions are within the scope of protection of the present invention.

[0049] Preferably, the rigid pad 4 includes a central cylinder and square plates respectively arranged at the upper end and the bottom end of the cylinder, so as to stably connect the leveling unit and the embedded part 3 and ensure stable transfer of the load.

[0050] Preferably, the upper surfaces of the plurality of rigid pads 4 are flush, and the elevation of the upper surfaces thereof is 0.8-1 cm lower than the design elevation when the grid plate 2 is installed, thereby providing necessary room for the leveling operation. It can be understood that according to the actual elevation of the upper surface of the embedded part 3, the actual elevation of the upper surface of the rigid pad 4 is reduced by a certain value, which can meet the redundant design concept in modern engineering, that is, various possible deviations are taken into account in the design stage, and appropriate adjustment space is reserved for them, thereby improving the flexibility of the leveling device.

[0051] Specifically, Figures 1 to 4 As shown, the leveling unit is disposed between the lower supporting component and the upper supporting component, and is used to achieve a leveling operation of the grid plate 2 by fine-tuning the height of the upper supporting component. The leveling unit includes: a first base 6, a first wedge block 7, a second wedge block 8, a first screw rod 9 and a second screw rod 10; wherein, the first base 6 is an L-shaped base as a whole, with its short side 61 facing the grille plate 2, and its long side 62 is bolted to the upper end of the rigid pad 4 and a slope 621 is provided on the long side 62, and the slope 621 extends from the end of the long side 62 from high to low to the inner side of the short side 61; the first wedge block 7 is arranged at the upper end of the first base 6, and the inclination of its lower surface is the same as that of the slope 621 and one side of it is parallel to the short side 61; the second wedge block 8 is arranged at the upper end of the first wedge block 7, and the inclination of its lower surface is the same as that of the upper surface of the first wedge block 7, and its upper surface is parallel to the lower surface of the grille plate 2; one end of the first screw rod 9 passes through the middle of the short side 61 and contacts with the first wedge block 7 and is rotatably connected to the short side 61; the second screw rod 10 passes through the support beam 5, the second wedge block 8, the first wedge block 7 in sequence and is connected to the first base 6. During use, the second screw 10 ensures that the leveling unit is stably connected to the support beam 5. At the same time, the first screw 9 is rotated to push the first wedge block 7 away from the short side 61, or rotated in the opposite direction to move the first wedge block 7 toward the short side 61 under the upper end load, so that fine-tuning can be achieved under load, ensuring that the height of the support beam 5 can be accurately controlled at the millimeter level; in addition, the first wedge block 7 and the second wedge block 8 are fine-tuned in coordination, so that the height adjustment of the grille plate 2 and the support beam 5 is more precise and a larger adjustment range is provided, thereby adapting to the redundant design of other components and improving the flexibility and practicality of the leveling device.

[0052] It can be understood that the support beam 5 is an H-shaped steel, whose web is parallel to the rigid pad 4, and whose flanges on both sides are respectively perpendicular to the lower surface of the grid plate 2 and the upper surface of the second wedge block 8, thereby reducing the amount of material used and reducing the self-weight of the overall structure while ensuring sufficient strength. At the same time, its standardized design also facilitates the connection of other components, thereby simplifying the construction process. Preferably, an auxiliary support plate is provided between the contact area between the two flanges and the grid plate 2, and an auxiliary support block is provided between the two flanges and the bottom end of the web and the contact area between the second wedge block 8 and the second screw 10, which is used to increase the contact area to evenly distribute the load, and at the same time, ensure the stability of the connection between the support beam 5 and the leveling unit.

[0053] Furthermore, the inclination of the upper surface and the inclination of the lower surface of the first wedge block 7 are both ≤ 40 degrees, so as to improve the stability and operational flexibility of the leveling unit. It can be understood that the inclination refers to the angle between the surface of the component and the plane where the lower surface of the long side 62 is located when the component is assembled, wherein the inclination of the upper surface and the inclination of the lower surface of the first wedge block 7 may be different. Preferably, the inclination of the upper surface and the inclination of the lower surface of the first wedge block 7 are the same.

[0054] Furthermore, the first wedge block 7 and the second wedge block 8 are provided with a waist hole in the middle part with the same axial direction as the first screw rod 9, and the width of the waist hole is adapted to the second screw rod 10. At the same time, the major diameter of the second screw rod 10 is smaller than the diameter of the corresponding through hole on the web of the support beam 5, and the size of the screw head at one end thereof is larger than the diameter of the corresponding through hole on the web of the support beam 5, and the elevation of the lower surface of the screw head is larger than the design elevation of the web of the support beam 5. It can be understood that in adjusting the height of the support beam 5 by rotating the first screw rod 9, the first wedge block 7 and the second wedge block 8 respectively move away from or toward the short side 61 in accordance with the axial direction of the first screw rod 9 through their internal waist holes and the second screw rod 10, thereby ensuring the stability of the leveling unit during operation; secondly, the design of the diameter of the through hole on the web of the support beam enables the support beam to move up and down smoothly along the second screw rod 10 during the leveling process, and at the same time, the connection form of the second screw rod 10 with the web can effectively reduce the overall length of the second screw rod 10 and improve the structural stability.

[0055] Preferably, a cushion block is provided at one end of the first screw rod 9 that contacts the first wedge block 7 , so as to increase the contact area between the first screw rod 9 and the first wedge block 7 and reduce the probability of possible damage to the first wedge block 7 .

[0056] Example 2

[0057] like Figure 5As shown, on the basis of Example 1, the adjustment unit of Example 2 of the present invention further includes: an electric push rod 11, a second base 12, a laser rangefinder 13 and a controller; wherein the electric push rod 11 is arranged outside the short side 61, and its telescopic end passes through the short side 61 and contacts the first wedge 7; the laser rangefinder 13 is arranged on the upper end of the grid plate 2 through the second base 12, and the signal transmitting end and the signal collecting end of the laser rangefinder 13 are both arranged above the hole of the grid plate 2; the controller is in communication connection with the electric push rod 11 and the laser rangefinder 13. During use, the controller receives the elevation signals of the plurality of laser rangefinders 13 on the upper surface of the grid plate 2 and replaces the first screw 9 through the electric push rod 11, so that the plurality of electric push rods 11 can be conveniently controlled to work through the controller to perform the leveling operation of the grid plate 2, thereby significantly improving the construction efficiency.

[0058] Preferably, the second base 12 is detachably mounted on the outer side of the grid plate 2 to facilitate the installation and debugging of the laser rangefinder 13 .

[0059] It should be noted that the controller in this embodiment may include: a processor, a network interface and a memory. In addition, the above-mentioned controller may also include: a user interface, and at least one communication bus. The communication bus is used to realize the connection and communication between these components. The user interface may include a display screen (Display) and a keyboard (Keyboard), and the optional user interface may also include a standard wired interface and a wireless interface. The network interface may optionally include a standard wired interface and a wireless interface (such as a WI-FI interface). The memory may be a high-speed RAM memory or a non-volatile memory (non-volatile memory), such as at least one disk memory. The memory may also be at least one storage device located away from the aforementioned processor. The memory as a computer-readable storage medium may include an operating system, a network communication module, a user interface module and a device control application. In addition, the network interface may provide a network communication function; the user interface is mainly used to provide an input interface for the user; and the processor may be used to call the device control application stored in the memory to realize: according to the design elevation of the upper surface of the grid plate 2 and the real-time elevation of the upper surface of the grid plate 2 measured by the laser rangefinder 13, the plurality of electric push rods 11 are controlled to work and the grid plate 2 is leveled.

[0060] It should be noted that in other embodiments, other types of rangefinders may be used, which are not specifically limited here, but all of these solutions are within the protection scope of the present invention.
