Description

Technical Field

[0001] This utility model relates to the field of bridge installation technology, and in particular to an auxiliary device for connecting prefabricated cap beams and columns. Background Technology

[0002] Traditional bridge construction largely relies on on-site rebar tying and pouring. Severe weather conditions such as strong winds, rain, and snow significantly impact construction, resulting in slow progress and high labor intensity for workers. To improve bridge construction efficiency, current methods typically involve prefabricating bridge components in factories, then transporting them to the site for assembly. This allows for rapid bridge construction and controllable quality.

[0003] In the installation of existing bridges, the docking and installation of precast cap beam components and columns usually requires the use of lifting equipment. However, due to factors such as external wind interference during the lifting process, the cap beam is easily deviated from its preset installation position after being lifted, which can easily lead to difficulties in docking and poor docking assembly between the cap beam and the column, resulting in reduced docking efficiency and accuracy.

[0004] Therefore, there is an urgent need to propose an auxiliary device for docking prefabricated cap beams and columns to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for docking prefabricated cap beams and columns, which can improve the docking efficiency and accuracy of cap beams and columns, improve the docking effect of the two, and improve the construction quality and efficiency of bridge construction.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model proposes a docking auxiliary device suitable for prefabricated cap beams and columns, comprising:

[0008] The lifting mechanism can be installed between two adjacent columns and can move up and down along the height of the columns;

[0009] The mounting components include a mounting platform, a first mounting base, and a second mounting base. The mounting platform is fixedly mounted on the output end of the lifting mechanism, and the first and second mounting bases are spaced apart on the top surface of the mounting platform.

[0010] The clamping mechanism includes a first clamping member and a second clamping member, wherein the first clamping member is slidably connected to a first mounting base and / or the second clamping member is slidably connected to a second mounting base, so that the first clamping member and the second clamping member can clamp or release the cover beam.

[0011] Optionally, the docking auxiliary device further includes a gear transmission assembly, which includes a first gear and a second gear that are connected in transmission. The first gear is rotatably disposed in a first mounting base, and a first rack portion that meshes with the first gear is slidably disposed in the first mounting base. The second gear is rotatably disposed in a second mounting base, and a second rack portion that meshes with the second gear is slidably disposed in the second mounting base. A first clamping member is fixedly connected to the first rack portion, and a second clamping member is fixedly connected to the second rack portion. When the first gear and the second gear rotate, they can drive the first clamping member and the second clamping member to move closer to or further away from each other.

[0012] Specifically, a third rack portion is slidably disposed within the first mounting base. The third rack portion and the first rack portion are symmetrically arranged along the length direction of the first mounting base. A first gear is disposed between the first rack portion and the third rack portion and meshes with the first rack portion and the third rack portion. A fourth rack portion is slidably disposed within the second mounting base. The fourth rack portion and the second rack portion are symmetrically arranged along the length direction of the second mounting base. A second gear is disposed between the second rack portion and the fourth rack portion and meshes with the second rack portion and the fourth rack portion. The two ends of the first clamping member are respectively fixedly connected to the first rack portion and the fourth rack portion, and the two ends of the second clamping member are respectively fixedly connected to the second rack portion and the third rack portion.

[0013] More specifically, the first rack portion has a first limiting member at both ends along its length, the second rack portion has a second limiting member at both ends along its length, the third rack portion has a third limiting member at both ends along its length, and the fourth rack portion has a fourth limiting member at both ends along its length. The top surface height of the first and third limiting members is not lower than the top surface height of the first mounting base, and the top surface height of the second and fourth limiting members is not lower than the top surface height of the second mounting base. Rotating the first gear and the second gear can drive the first and / or third limiting members at different ends to abut against the wall of the first mounting base, and drive the second and / or fourth limiting members at different ends to abut against the wall of the second mounting base.

[0014] Optionally, the gear transmission assembly further includes a drive gear and a driving member. The drive gear is rotatably mounted on the mounting platform and is transmissionally connected to the first gear and the second gear. The driving member is configured to drive the drive gear to rotate, thereby causing the first gear and the second gear to rotate synchronously.

[0015] Specifically, the gear transmission assembly also includes a conveyor belt, which is sleeved on the gear shafts of the drive gear, the first gear, and the second gear. The drive gear is connected to the first gear and the second gear via the conveyor belt.

[0016] Optionally, multiple rollers are rotatably provided on the side of the first clamping member and the second clamping member that are close to each other, and each roller can abut against the cover beam.

[0017] Specifically, the outer periphery of the rollers is provided with an anti-slip layer, which can abut against the cap beam.

[0018] For example, the bottom of the lifting mechanism is rotatably equipped with lockable wheels.

[0019] Optionally, the lifting mechanism is a jack.

[0020] The beneficial effects of this utility model are:

[0021] This invention proposes an auxiliary device for docking prefabricated cap beams and columns. The first and second clamping members work together to hold the cap beam, preventing horizontal deviations between the cap beam and column due to external environmental influences during lifting. The clamping mechanism improves the docking effect between the cap beam and column, enhancing docking efficiency and accuracy. The sliding connection of at least one of the first and second clamping members allows for flexible adjustment of the distance between them, improving the versatility and stability of the clamping mechanism for cap beams of different sizes. The lifting mechanism can move up and down along the height of the column, which can drive the installation platform fixed to its output end and the first and second mounting seats on the top of the installation platform to move up and down synchronously. This allows the first clamping member connected to the first mounting seat and the second clamping member connected to the second mounting seat to move up and down to stably clamp the cap beam being lifted by the lifting equipment. The lifting mechanism enables flexible adjustment of the clamping mechanism relative to the cap beam in the vertical direction, which not only ensures the clamping stability and reliability of the clamping mechanism on the cap beam, but also meets the different requirements for the installation height of the cap beam in various construction scenarios.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] To improve bridge construction efficiency, existing bridges typically have their cap beam components pre-manufactured in factories before installation. During installation, only lifting equipment is needed to assemble the cap beam components with the columns. However, due to factors such as external wind interference during lifting, the cap beam components are prone to swaying and deviating from their intended installation positions after lifting. This can easily lead to difficulties in connecting the cap beams and columns, or poor assembly results, reducing connection efficiency and accuracy.

[0037] To solve the above problems, such as Figures 1-3 As shown, this embodiment provides a docking auxiliary device suitable for prefabricated cap beams and columns, including a lifting mechanism 1, an installation component 2, and a clamping mechanism 3. The lifting mechanism 1 can be set between two adjacent columns 5 and move up and down along the height direction of the columns 5. The installation component 2 includes an installation platform 21, a first mounting seat 22, and a second mounting seat 23. The installation platform 21 is fixedly set at the output end of the lifting mechanism 1, and the first mounting seat 22 and the second mounting seat 23 are spaced apart on the top surface of the installation platform 21. The clamping mechanism 3 includes a first clamping member 31 and a second clamping member 32. The first clamping member 31 is slidably connected to the first mounting seat 22 and / or the second clamping member 32 is slidably connected to the second mounting seat 23, so that the first clamping member 31 and the second clamping member 32 can clamp or release the cap beam 6. It is understood that all three installation methods—first clamping member 31 slidably connected to first mounting base 22 and second clamping member 32 slidably connected to second mounting base 23, first clamping member 31 slidably connected to first mounting base 22 and second clamping member 32 fixedly connected to second mounting base 23, and first clamping member 31 fixedly connected to first mounting base 22 and second clamping member 32 slidably connected to second mounting base 23—can achieve the clamping or releasing process of the first clamping member 31 and second clamping member 32 on the cover beam 6. In this embodiment, the first mounting base 22 and the second mounting base 23 are parallel to each other, and their length direction is consistent with the width direction of the cover beam 6 and perpendicular to the length direction of the mounting platform 21. The first clamping member 31 and the second clamping member 32 can slide relative to each other along the length direction of the first mounting base 22 to clamp the cover beam 6 in the width direction of the cover beam 6, which will not be described in detail hereafter.

[0038] In this embodiment, as Figure 1 and Figure 2As shown, the first clamping member 31 and the second clamping member 32 can jointly clamp the cap beam 6, avoiding horizontal deviation of the cap beam 6 relative to the column 5 due to external environmental influences during lifting. The clamping mechanism 3 improves the docking effect between the cap beam 6 and the column 5, enhancing the docking efficiency and accuracy. The sliding connection of at least one of the first clamping member 31 and the second clamping member 32 allows for flexible adjustment of the distance between them, improving the clamping mechanism 3's versatility and stability in clamping cap beams 6 of different sizes. The lifting mechanism 1, moving up and down along the height of the column 5, can synchronously lift and lower the installation platform 21 fixed to its output end, and the first mounting seat 22 and the second mounting seat 23 on the top of the installation platform 21. This allows the first clamping member 31 connected to the first mounting seat 22 and the second clamping member 32 connected to the second mounting seat 23 to be raised and lowered to stably clamp the cap beam 6 being lifted by the hoisting equipment. The lifting mechanism 1 enables flexible adjustment of the clamping mechanism 3 relative to the cap beam 6 in the vertical direction, ensuring both the stability and reliability of the clamping mechanism 3 on the cap beam 6, and meeting the diverse needs for the installation height of the cap beam 6 in various construction scenarios. It should be noted that the cap beam 6 in this embodiment is a precast component. Compared to traditional bridges that rely on on-site rebar binding and pouring, precasting the cap beam 6 and then using hoisting equipment and docking auxiliary devices to assemble the cap beam 6 with the column 5 significantly improves the construction quality and efficiency of the bridge and reduces the intensity of manual labor in the construction work.

[0039] Optionally, multiple rollers 33 are rotatably provided on the side of the first clamping member 31 and the second clamping member 32 that are close to each other, and each roller 33 can abut against the cover beam 6. The rollers 33 reduce the rigid collision or compression of the cover beam 6 by the first clamping member 31 and the second clamping member 32 during the clamping process, ensuring the structural quality and integrity of the cover beam 6 during the clamping process. The multiple rollers 33 also improve the clamping effect of the first clamping member 31 and the second clamping member 32 on cover beams 6 with different outer surface shapes or structural designs.

[0040] Specifically, the outer periphery of the rollers 33 is provided with an anti-slip layer, which can abut against the cover beam 6. The anti-slip layer on the outer periphery of the rollers 33 prevents slippage when the first clamping member 31 and the second clamping member 32 clamp the cover beam 6, thereby improving the clamping stability and reliability of the first clamping member 31 and the second clamping member 32 on the cover beam 6.

[0041] Specifically, such as Figures 1-3As shown, the docking auxiliary device also includes a gear transmission assembly 4, which includes a first gear 41 and a second gear 42 connected in transmission. The first gear 41 is rotatably disposed in the first mounting base 22, and a first rack portion 221 that meshes with the first gear 41 is slidably disposed in the first mounting base 22. The second gear 42 is rotatably disposed in the second mounting base 23, and a second rack portion 231 that meshes with the second gear 42 is slidably disposed in the second mounting base 23. A first clamping member 31 is fixedly connected to the first rack portion 221, and a second clamping member 32 is fixedly connected to the second rack portion 231. When the first gear 41 and the second gear 42 rotate, they can drive the first clamping member 31 and the second clamping member 32 to move closer to or further away from each other. When the first gear 41 rotates, it drives the first rack portion 221, which meshes with it, to slide within the first mounting base 22, thereby enabling the first clamping member 31, which is fixedly connected to the first rack portion 221, to slide relative to the first mounting base 22. When the second gear 42 rotates, it drives the second rack portion 231, which meshes with it, to slide within the second mounting base 23, thereby enabling the second clamping member 32, which is fixedly connected to the second rack portion 231, to slide relative to the second mounting base 23. The transmission connection between the first gear 41 and the second gear 42 allows the process of the first clamping member 31 and the second clamping member 32 moving closer or further away from each other to be realized synchronously, thereby improving the clamping stability of the first clamping member 31 and the second clamping member 32 on the cover beam 6. Furthermore, the sliding process of the first clamping member 31 and the second clamping member 32 is achieved by means of the meshing relationship between the first gear 41 and the first rack portion 221 and the meshing relationship between the second gear 42 and the second rack portion 231, which improves the sliding stability of the first clamping member 31 and the second clamping member 32. Moreover, the position adjustment of the first clamping member 31 and the second clamping member 32 can be achieved by rotating the first gear 41 and the second gear 42, which is easy to operate and implement.

[0042] More specifically, such as Figure 2 and Figure 3As shown, a third rack portion 222 is slidably disposed within the first mounting base 22. The third rack portion 222 and the first rack portion 221 are symmetrically arranged along the length direction of the first mounting base 22. A first gear 41 is disposed between the first rack portion 221 and the third rack portion 222 and meshes with the first rack portion 221 and the third rack portion 222. A fourth rack portion 232 is slidably disposed within the second mounting base 23. The fourth rack portion 232 and the second rack portion 231 are symmetrically arranged along the length direction of the second mounting base 23. A second gear 42 is disposed between the second rack portion 231 and the fourth rack portion 232 and meshes with the second rack portion 231 and the fourth rack portion 232. The two ends of the first clamping member 31 are respectively fixedly connected to the first rack portion 221 and the fourth rack portion 232, and the two ends of the second clamping member 32 are respectively fixedly connected to the second rack portion 231 and the third rack portion 222. Adding a third rack portion 222 symmetrically arranged with the first rack portion 221 along the length direction of the first mounting base 22 reduces the risk of local stress concentration within the first mounting base 22 when the first gear 41 drives the first rack portion 221 to slide, compared to only having the first rack portion 221. Adding a fourth rack portion 232 symmetrically arranged with the second rack portion 231 along the length direction of the second mounting base 23 reduces the risk of local stress concentration within the second mounting base 23 when the second gear 42 drives the second rack portion 231 to slide, compared to only having the second rack portion 231. Furthermore, one end of the first clamping member 31 along its own length direction is fixedly connected to the first rack portion 221, and the other end is fixedly connected to the fourth rack portion 232. One end of the second clamping member 32 along its own length direction is fixedly connected to the second rack portion 231, and the other end is fixedly connected to the third rack portion 222. The addition of the third rack portion 222 and the fourth rack portion 232 also reduces the load-bearing requirements of the first rack portion 221 and the second rack portion 231, as well as the driving cost of the first gear 41 and the second gear 42.

[0043] In this embodiment, the docking auxiliary device is first placed in the middle of two adjacent columns 5. Then, the lifting mechanism 1 drives the installation component 2 to rise until the first clamping member 31 and the second clamping member 32 at least partially protrude from the top surface of the column 5. The cap beam 6 is then lifted between the first clamping member 31 and the second clamping member 32 using a lifting device. The first gear 41 and the second gear 42 are driven to rotate, so that the first rack portion 221 and the fourth rack portion 232 drive the first clamping member 31 to approach the cap beam 6, and the second rack portion 231 and the third rack portion 222 drive the second clamping member 32 to approach the cap beam 6, until the first clamping member 31 and the second clamping member 32 jointly clamp the cap beam 6, limiting the swaying amplitude of the cap beam 6, improving the positioning accuracy of the cap beam 6, and ensuring the structural stability and construction quality of the bridge after assembly. Finally, the lifting mechanism 1 and the hoisting equipment drive the cover beam 6 to descend and stably abut against the column 5, driving the first gear 41 and the second gear 42 to reverse, causing the first clamping member 31 and the second clamping member 32 to release the cover beam 6, thus completing the auxiliary operation of the docking auxiliary device.

[0044] Furthermore, the first rack portion 221 has a first limiting member 2211 at both ends along its length, the second rack portion 231 has a second limiting member 2311 at both ends along its length, the third rack portion 222 has a third limiting member 2221 at both ends along its length, and the fourth rack portion 232 has a fourth limiting member 2321 at both ends along its length. The top surface height of the first limiting member 2211 and the third limiting member 2221 is... The height of the top surface of the first mounting base 22 is not lower than that of the top surface of the second limiting member 2311 and the fourth limiting member 2321. The height of the top surface of the second limiting member 2311 and the fourth limiting member 2321 is not lower than that of the top surface of the second mounting base 23. Rotating the first gear 41 and the second gear 42 can drive the first limiting member 2211 and / or the third limiting member 2221 at different ends to abut against the wall surface of the first mounting base 22, and drive the second limiting member 2311 and / or the fourth limiting member 2321 at different ends to abut against the wall surface of the second mounting base 23. The top surface heights of the first limiting member 2211 and the third limiting member 2221 are not lower than the top surface height of the first mounting base 22, and the top surface heights of the second limiting member 2311 and the fourth limiting member 2321 are not lower than the top surface height of the second mounting base 23. The two ends of the first clamping member 31 are respectively fixedly connected to the first rack portion 221 and the fourth rack portion 232, and the two ends of the second clamping member 32 are respectively fixedly connected to the second rack portion 231 and the third rack portion 222. This ensures that regardless of whether the two ends of the first clamping member 31 are respectively disposed on the first limiting member 2211 and the fourth limiting member 2321 at the same end of the length direction of the first mounting base 22, or the first end of the first clamping member 31 is disposed on the two first limiting members 2211 and the fourth limiting member 2321, this arrangement ensures that the first clamping member 31 is positioned on either of the two first limiting members 2211 and the fourth limiting member 2321. Between the first clamping member 2211, the second end is disposed between the two fourth limiting members 2321. The first limiting member 2211 can prevent the first clamping member 31 from directly contacting or colliding with one side wall of the first mounting base 22 when it slides. The fourth limiting member 2321 can replace the first clamping member 31 to directly contact or collide with one side wall of the second mounting base 23. The principle of the second limiting member 2311 is the same as that of the fourth limiting member 2321, which can limit the direct contact or collision between the second clamping member 32 and the second mounting base 23. The principle of the third limiting member 2221 is the same as that of the first limiting member 2211, which can limit the direct contact or collision between the second clamping member 32 and the first mounting base 22. The first limiting member 2211, the second limiting member 2311, the third limiting member 2221 and the fourth limiting member 2321 are provided to avoid direct collision between the first clamping member 31 and the second clamping member 32 and the first mounting base 22 and the second mounting base 23 during the sliding process, thereby extending the structural service life of the first clamping member 31 and the second clamping member 32.

[0045] It is understandable that when the first gear 41 is rotatably positioned at the center of the first mounting base 22, its rotation can cause the first limiting member 2211 and the third limiting member 2221, located at different ends along the length of the first mounting base 22, to simultaneously abut against the walls on opposite sides of the first mounting base 22. When the rotation center of the first gear 41 is not at the center of the first mounting base 22, its rotation can only cause either the first limiting member 2211 or the third limiting member 2221 at one end along the length of the first mounting base 22 to abut against the wall on one side of the first mounting base 22 along its length. For the first limiting member 2211 and the third limiting member 2221 located at different ends, one abutting against the wall of the first mounting base 22 indicates that the first clamping member 31 has reached its maximum sliding path along its end. The second limiting member 2311 and the fourth limiting member 2321 have the same setting mechanism as the first limiting member 2211 and the third limiting member 2221, and will not be described in detail here.

[0046] In some embodiments, the rotation of the first gear 41 and the second gear 42 can be achieved by a first drive motor installed in the first mounting base 22 to drive the first gear 41 to rotate, thereby driving the second gear 42, which is connected to the first gear 41, to rotate; or by a second drive motor installed in the second mounting base 23 to drive the second gear 42 to rotate, thereby driving the first gear 41, which is connected to the second gear 42, to rotate.

[0047] In some other embodiments, the gear transmission assembly 4 further includes a drive gear 43 and a driving member. The drive gear 43 is rotatably mounted on the mounting platform 21 and is drively connected to the first gear 41 and the second gear 42. The driving member is configured to drive the drive gear 43 to rotate, thereby causing the first gear 41 and the second gear 42 to rotate synchronously. Mounting the drive gear 43 on the mounting platform 21 reduces the space occupied inside the first mounting base 22 or the second mounting base 23. Driving the drive gear 43 with the driving member enables synchronous rotation of the first gear 41 and the second gear 42, improving the efficiency of adjusting the distance between the first clamping member 31 and the second clamping member 32. The driving member can be a hydraulic motor or a drive motor, etc., and its specific structure and working principle are existing technologies and will not be elaborated further here. It is understood that the drive gear 43 is located at the center of the mounting platform 21, and the mounting positions of the first gear 41 and the second gear 42 are symmetrically distributed relative to the drive gear 43 along the length of the mounting platform 21 to improve the uniformity of the load-bearing capacity of the mounting platform 21. Both the first mounting base 22 and the second mounting base 23 are provided with mounting slots. The first gear 41 is set in the mounting slot of the first mounting base 22, and the second gear 42 is set in the mounting slot of the second mounting base 23. Further details will not be provided hereafter.

[0048] The transmission connection between the drive gear 43, the first gear 41, and the second gear 42 can be achieved using a gear set or a conveyor belt 44. The conveyor belt 44 is fitted onto the gear shafts of the drive gear 43, the first gear 41, and the second gear 42. The drive gear 43 is driven to the first gear 41 and the second gear 42 via the conveyor belt 44. Using the conveyor belt 44 to achieve the transmission connection among the three reduces transmission and maintenance costs, and also reduces the requirement for reserved installation space on the mounting platform 21. It is understood that the first mounting base 22 and the second mounting base 23 are both provided with clearance grooves on their adjacent sides, so that both sides of the conveyor belt 44 can be fitted onto the first gear 41 and the second gear 42 respectively via the clearance grooves.

[0049] For example, the bottom of the lifting mechanism 1 is rotatably equipped with lockable wheels 11. The lifting mechanism 1 can be installed between two adjacent columns 5 and directly on the construction ground. The wheels 11 effectively reduce the difficulty for workers to move the lifting mechanism 1 and reduce the labor intensity of workers during the movement. The lockable wheels 11 greatly improve the positional stability of the lifting mechanism 1 after it is installed, ensuring the smooth progress of subsequent auxiliary work for connecting the cap beam 6 and the column 5.

[0050] Specifically, the lifting mechanism 1 can be a jack, offering high adjustment precision and good load-bearing capacity, suitable for medium to heavy-duty lifting needs. Alternatively, the lifting mechanism 1 can be a scissor lift, capable of covering a wide range of lifting strokes, possessing a large load-bearing area and strong load-bearing stability. The specific structure and working principle of the lifting mechanism 1 are existing technologies and will not be elaborated upon here.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
