Description

Technical Field

[0001] This utility model relates to the field of bridge structure technology, and more specifically, to a bridge bearing replacement and delivery device. Background Technology

[0002] my country is prone to earthquakes, and after an earthquake, bridge bearings may be damaged or even fail, necessitating bearing replacement to restore the bridge's seismic resistance. However, bearing replacement presents varying degrees of difficulty. As the vertical load-bearing capacity of the bearings increases, their dimensions and weight also increase. On the one hand, compared to the bearing size and the planar space at the pier top, the space between the pier top and the beam bottom is relatively small, making bearing replacement more challenging as it often occurs within this confined space. On the other hand, the equipment required for lifting and replacing large-tonnage bearings is larger and more powerful, requiring more auxiliary tools and personnel, and extending the time spent disrupting traffic. Therefore, the ability to quickly and effectively replace large-tonnage bearings directly determines the economic and social benefits of subsequent operation.

[0003] Existing equipment for replacing bridge bearings after earthquakes is large, inconvenient to use, has relatively limited functionality, and low replacement efficiency. Prior art (CN117536140A) discloses a bridge bearing replacement device and method, including a clamp surrounding the pier, a slide rail rotatably mounted on the clamp, a sliding seat slidably mounted on the slide rail, a drive rod hinged to the sliding seat, a mounting base on the top surface of the pier, and a first drive component for driving the sliding seat to slide. The slide rail is arranged parallel or perpendicular to the bridge's orientation and is fixedly mounted at the bottom of the bridge. The end of the drive rod away from the sliding seat is hinged to the mounting base, and the drive rod is inclined away from the pier. The sliding seat slides along the length of the slide rail. The existing device is only suitable for replacing small-tonnage bearings with low loads and low pier heights, and is not suitable for replacing large-stroke, large-tonnage bearings in confined spaces. Utility Model Content

[0004] In view of this, the present invention aims to provide a bridge bearing replacement and delivery device. This addresses the problem that existing devices are only suitable for replacing small-tonnage bearings with relatively low loads and low pier heights, and are not suitable for replacing large-stroke, large-tonnage bearings in confined spaces.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A bridge bearing replacement and delivery device includes a bearing delivery assembly for moving bearings and a lifting and delivery assembly for moving jacks. The bearing delivery assembly is independent of the lifting and delivery assembly. The bearing delivery assembly includes a bearing telescopic part, a bearing drive part, and a bearing pickup part. The bearing drive part is located on the bearing telescopic part, and the bearing pickup part is connected to the bearing drive part. The bearing drive part drives the bearing pickup part so that the bearing pickup part can clamp the bearing. The bearing telescopic part is used to realize the synchronous movement of the bearing drive part and the bearing pickup part.

[0007] In this setup, the support transfer and jack transfer are carried out separately, which effectively reduces manual intervention and improves the efficiency and safety of support replacement. Furthermore, the support pick-up unit clamps the support, and the support extension unit simultaneously drives the support drive unit and the support pick-up unit. This not only enables the replacement of large-stroke, large-tonnage supports in confined spaces, but also makes the movement of the support more stable, resulting in high efficiency and high precision in support replacement.

[0008] Furthermore, the support pickup unit includes a drive support plate, a movable component, and a support component. The drive support plate is movably connected to the support drive unit. The movable component is disposed on the drive support plate and connected to the support component. The support component is used to support the support.

[0009] This setup reduces manual intervention in the clamping process of the bearings by incorporating a drive support plate, moving parts, and support components. This setup can accurately clamp and move large-tonnage bearings, providing more stable support for large-tonnage bearings and increasing the efficiency of bearing replacement.

[0010] Furthermore, the drive support plate is provided with a groove, and the moving part is disposed in the groove.

[0011] This design, with the movable part positioned within the groove, makes the support pickup section more compact, reducing space occupation and enabling support replacement in confined spaces.

[0012] Furthermore, the support drive unit includes a fixed plate and a drive component. The fixed plate is disposed on the support telescopic part and is movably connected to the drive support plate. The drive component is disposed on the fixed plate and is movably connected to the drive support plate.

[0013] In this setup, the fixed plate supports the drive components, ensuring their efficiency, and, in conjunction with the drive support plate, enables more stable clamping and transfer of large-tonnage supports.

[0014] Furthermore, a movable guide rail is provided at the bottom of the groove, and the second movable track moves on the movable guide rail.

[0015] Furthermore, the moving component includes a second moving track, and the supporting component includes a second rolling column and a vertical moving plate. The second rolling column is connected to the vertical moving plate, and the second rolling column slides on the second moving track.

[0016] This setup enables precise positioning during the clamping process of the support, resulting in high replacement efficiency. It also reduces space occupation, making the structure more compact and suitable for replacing supports in confined spaces.

[0017] Furthermore, the driving component includes a driving body and a rotating disc, the driving body being connected to the rotating disc, and the rotating disc being movably connected to a driving support plate.

[0018] The rotating disc in this configuration is movably connected to the drive support plate, enabling the support plate to rotate freely and effectively clamp the support. The connection between the drive body and the rotating disc also ensures the connection stability of the support drive unit, supporting large-tonnage supports and improving replacement efficiency.

[0019] Furthermore, it also includes a lifting and transferring assembly, which includes an elastic clamping member, a rotating member, and a lifting member. The elastic clamping member is connected to the rotating member, and the rotating member is connected to the lifting member.

[0020] In this setup, the gripper can quickly and accurately hold the support, avoiding the locking issues associated with manual positioning and adjustment. The rotating component allows the gripper and support to rotate in the horizontal plane to accommodate support replacement needs at different angles and directions. The lifting component and the jacking drive work together to quickly and smoothly lift the support to the required height and lower it to the installation position, reducing waiting time during the replacement process and improving overall work efficiency.

[0021] Furthermore, the rotating component includes a support base, a telescopic sliding plate, and a clamping and fixing plate. The rising component is connected to the support base, the support base is connected to the telescopic sliding plate, and the telescopic sliding plate is connected to the clamping and fixing plate.

[0022] This setup effectively supports the jacks and allows for their movement, improving the efficiency of support replacement.

[0023] Furthermore, the lifting component includes a lifting seat, a first rolling column, and a first moving track. The support seat is connected to the lifting seat, and the lifting seat is connected to the first rolling column, which rolls on the first moving track.

[0024] This setting allows adjustment of the jack's position so that it can mate with the support, enabling quick support replacement.

[0025] Compared with the prior art, the bridge bearing replacement and delivery device of this utility model has the following advantages:

[0026] 1) The support transfer and jack transfer of this utility model are carried out separately, which effectively reduces manual intervention and improves the efficiency and safety of support replacement. In addition, the support picking part clamps the support, and the support telescopic part drives the support driving part and the support picking part to run at the same time. This not only enables the replacement of large-stroke and large-tonnage supports in narrow spaces, but also makes the movement of the support more stable during replacement, and the support replacement efficiency and accuracy are high.

[0027] 2) By setting up a drive support plate, a moving part, and a support part, this utility model reduces the manual participation in the clamping process of the support. This setting can accurately clamp and move large-tonnage supports, provide more stable support for large-tonnage supports, and increase the efficiency of support replacement.

[0028] 3) By setting a groove and placing the moving part in the groove, the structure of the support pickup part is more compact, reducing space occupation and enabling the replacement of the support in a narrow space.

[0029] 4) The clamping component of this utility model can quickly and accurately clamp the support, avoiding the locking of manual positioning and adjustment. The rotating component allows the clamping component and the support to rotate in the horizontal plane to adapt to the support replacement needs of different angles and directions. The lifting component and the lifting drive component work together to quickly and smoothly lift the support to the required height and lower it to the installation position, reducing the waiting time during the replacement process and improving the overall work efficiency.

Detailed Implementation

[0040] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. In addition, a brief explanation of the orientations involved in the following specific embodiments is provided: the directions or positional relationships indicated by "front," "back," "up," "down," "left," and "right" mentioned in the embodiments refer to the orientations or positional relationships shown in the accompanying drawings.

[0041] Example 1

[0042] like Figures 1-8 As shown, the existing bridge 2 has a small height between its bottom and the top of the pier 1, within the range of 90cm-110cm. To address how to replace the bearings within this narrow range, this utility model proposes a bridge bearing replacement and delivery device and method. The replacement and delivery device includes a lifting assembly 3, a support assembly 4, a lifting and transferring assembly 5, a bearing transfer assembly 6, a jack 7, and a bearing 8. The support assembly 4 is connected to the pier 1, and the lifting assembly 3 is connected to the support assembly 4. The lifting assembly is used for transporting the old and new bearings, the bearing transfer assembly, the lifting and transferring assembly, and the jack. The lifting and transferring assembly is mounted on the lifting assembly and is used to move the jack. The bearing transfer assembly is located on the lifting assembly and is used to transfer the bearing.

[0043] The relatively independent jacking and moving components and bearing moving components in this setup can move jacks and bearings separately, which is not only highly efficient but also suitable for confined spaces. The bearing moving component is more stable when moving large-tonnage bearings, resulting in high bearing replacement efficiency. The setting of support components and lifting components not only reduces manual intervention but also improves the stability and efficiency of replacing large-tonnage bearings. It can also replace bearings with pier heights ranging from 20m to 40m, and can even replace bearings with heights below 20m.

[0044] Specifically, the jack is a hydraulic jack.

[0045] Specifically, the support 8 includes a first segment 81 and a second segment 82 connected in sequence. The first segment 81 is located at the top of the support and has a cuboid structure. The second segment 82 has a circular cross-section. The support transfer assembly is used to transfer the support 8.

[0046] Specifically, the lifting assembly 3 includes a lifting plate and a driving mechanism. The driving mechanism is connected to the lifting plate. The lifting plate is used to support the support transfer assembly and the lifting transfer assembly. The driving mechanism can stably drive the lifting plate under the support of the support assembly, which will not be described in detail here.

[0047] Specifically, the support component 4 can be constructed using multiple frames and connected to the bridge piers, as long as the stability of the support component can be guaranteed, which will not be described in detail here.

[0048] Specifically, the lifting and transferring assembly 5 includes an elastic clamping member 51, a rotating member 52, a lifting member 53, a lifting drive member 54, and a lifting base 55. The elastic clamping member 51 is connected to the rotating member 52, the rotating member 52 is connected to the lifting member 53, the lifting member 53 is connected to the lifting drive member 54, and the drive member 54 is mounted on the lifting base 55. This clamping member can quickly and accurately grip the support, avoiding the locking issues associated with manual positioning and adjustment. The rotating member allows the clamping member and the support to rotate in the horizontal plane to accommodate support replacement needs at different angles and directions. The lifting member and the lifting drive member work together to quickly and smoothly lift the support to the required height and lower it to the installation position, reducing waiting time during replacement and improving overall work efficiency.

[0049] More specifically, the elastic clamping member 51 includes a fixed hinge and a spring connected to each other. The fixed hinge is movably connected to the rotating member. Under the action of the spring, the fixed hinge can be rotated open and closed to realize the clamping and releasing of the jack. That is, when clamping or releasing the jack, by pushing the fixed hinge closer to or away from the jack, the clamping or releasing of the jack is realized under the action of the spring and the fixed hinge.

[0050] More specifically, the rotating component 52 includes a support base 521, a telescopic sliding plate 522, a clamping and fixing plate 523, and a telescopic rod 524. The rising component is connected to the support base 521, the support base 521 is connected to the telescopic sliding plate 522, the telescopic sliding plate 522 is slidably connected to the clamping and fixing plate 523, the clamping and fixing plate 523 is connected to the telescopic rod 524, the telescopic rod 524 is fixed on the support base 521, and the telescopic rod is connected to a drive cylinder (not shown in the figure).

[0051] Specifically, the support base 521 is rotatably connected to the lifting member. More specifically, a bearing is provided between the support base and the lifting member, and the support base is connected to a drive motor (not shown in the figure). The rotation of the drive motor drives the rotation of the support base. The bearing is a conventional prior art and will not be described in detail here.

[0052] More specifically, the lifting component 53 includes a lifting seat 531, a first rolling column 532, and a first moving track 533. The support seat 521 is movably connected to the lifting seat 531 via a bearing, allowing the lifting seat to rotate and adjust the position of the jack. The lower end of the lifting seat 531 is connected to the first rolling column 532, which rolls on the first moving track 533. This configuration allows for adjustment of the jack's position, enabling it to engage with the support and quickly replace the support.

[0053] Preferably, the second moving track is a ramp structure.

[0054] Specifically, the lifting drive component 54 includes, from right to left, a drive cylinder, a drive shaft, and a connecting seat connected in sequence. The drive cylinder is mounted on a telescopic track, and the connecting seat is connected to the first moving track.

[0055] Specifically, the lifting base 55 includes a first limiting post 551, a fixed guide rail plate 552, and a lifting telescopic mechanism 553. One end of the first limiting post is fixed to the fixed guide rail plate, and the first limiting post passes through the lifting base. The fixed guide rail and the lifting drive component are both mounted on the lifting telescopic mechanism. The lifting telescopic mechanism can be a three-stage telescopic structure, which can realize large stroke movement of the elastic clamping component 51, the rotating component 52, the lifting component 53, and the lifting drive component 54.

[0056] Specifically, the support transfer assembly 6 includes a support telescopic part 61, a support driving part 62, and a support picking part 63. The support driving part 62 is located on the support telescopic part 61, and the support picking part 63 is connected to the support driving part 62. The support driving part is used to drive the support picking part so that the support picking part can clamp the support. The support telescopic part is used to realize the synchronous movement of the support driving part and the support picking part.

[0057] This setup uses a support pickup unit to hold the support, and the support telescopic unit simultaneously drives the support drive unit and the support pickup unit to operate, enabling the large-tonnage support to move smoothly, improving the replacement efficiency of the large-tonnage support, and also ensuring high replacement accuracy. The support transfer assembly can bear a load of 40 tons, and the support transfer assembly has a symmetrical structure, with an average load capacity of 20 tons per side.

[0058] More specifically, there are two support pickup units 63, which are symmetrically arranged about the axis centerline of the support drive unit.

[0059] More specifically, there are two support telescopic parts 61, which are symmetrical about the axis center line of the support drive part 62. Each support telescopic part 61 includes a track moving plate 611 and a track motor 612. The track motor 612 is mounted on the track moving plate, and the support drive part 62 is mounted on the track moving plate. Multiple telescopic moving structures can be set on the track moving plate as needed. This is a conventional setting and will not be described in detail here.

[0060] Specifically, the support pickup unit 63 includes a drive support plate 631, a movable member, and a support member. The drive support plate 631 is movably connected to the support drive unit. The movable member is disposed on the drive support plate 631 and connected to the support member. The support member is used to support the support.

[0061] More specifically, the drive support plate 631 is provided with a groove 6311, a second limiting post 6312, and a third limiting post 6313. The moving part is disposed in the groove 6311. The second limiting post and the third limiting post are both disposed at the upper end of the drive support plate. One end of the second limiting post is connected to the drive part, and the other end of the second limiting post passes through the drive support plate.

[0062] This design incorporates a groove, with the moving part positioned within it, resulting in a more compact support pickup structure that reduces space requirements. This allows for support replacement even in confined spaces. Furthermore, the inclusion of a second and third limiting post enables more stable adjustment of the support's movement, thereby improving work efficiency.

[0063] More specifically, the moving component includes a second moving track 633, and the supporting component includes a second rolling column 634 and a vertical moving plate 635. The vertical moving plate 635 is movably connected to the drive support plate via a third limiting post. The second rolling column 634 is connected to the vertical moving plate 635 and slides on the second moving track 633. Under the constraint of the third limiting post, the vertical moving plate moves stably up and down. This design makes the support pickup section more compact, reduces space occupation, and enables the replacement of supports in confined spaces.

[0064] More specifically, one end of the third limiting post is connected to the drive support plate, and the other end of the third limiting post passes through the vertical support plate.

[0065] More specifically, a movable guide rail is provided at the bottom of the groove 6311, and the second movable track moves on the movable guide rail. The moving component also includes a second driving body 632 and a cylinder shaft connected to each other. The cylinder shaft is connected to the second movable track, and the second moving track is driven to move by the second driving body.

[0066] More specifically, a track plate is provided at the bottom of the second moving track, and the second moving track moves on the track plate.

The fixed plate 621 is disposed on the support telescopic part 61 and is movably connected to the support pickup part 63. The drive component is disposed on the fixed plate 621 and is movably connected to the support pickup part 63. In this configuration, the fixed plate supports the drive component, ensuring its efficiency, and, in conjunction with the drive support plate, enables more stable clamping and transfer of large-tonnage supports.

[0069] More specifically, the fixed plate 621 is movably connected to the drive support plate 631, and the drive component is movably connected to the drive support plate 631.

[0070] Specifically, the fixing plate 621 is disposed on the track moving plate of the support telescopic part 61, and the fixing plate 621 is movably connected to the drive support plate. The drive component is disposed on the fixing plate 621 and is movably connected to the drive support plate 631.

[0071] More specifically, the driving component includes a driving body 622 and a rotating disc 623. The driving body 622 is connected to the rotating disc 623, and the rotating disc 623 is movably connected to the driving support plate 631. Preferably, the driving body is a driving cylinder.

[0072] More specifically, the drive cylinder 322 is connected to a drive shaft, and a fixed frame is connected to the drive shaft. The fixed frame has a through hole through which the drive shaft passes, and a spring is installed on the drive shaft. The fixed frame is connected to the drive support plate via a rotating disc. By driving the drive shaft with the drive cylinder, the rotating disc rotates to a certain extent, giving the support pickup part a certain degree of opening and closing, which facilitates the clamping of the support in confined spaces.

[0073] Specifically, the replacement and delivery device also includes a visual positioning system and an intelligent control system hardware framework. The automatic identification and assisted positioning of workpieces based on machine vision are incorporated into the intelligent control framework. As long as efficient and visual human-computer interaction can be achieved, the difficulty of operation can be reduced, and the level of unmanned and intelligent support replacement can be improved, it is acceptable. It will not be described in detail here.

[0074] Example 2

[0075] A method for replacing and delivering bridge bearings, using the replacement and delivery device described in Example 1, includes the following steps:

[0076] S1. Organize the crane next to the bridge pier, install the support components and lifting components, test each component to ensure normal operation, and complete the preparation work; the lifting and transfer component clamps the jacks and places them on the lifting component, and the lifting component moves to a position level with the top of the bridge pier;

[0077] S2. The jacks are transported between the bridge and the piers by the lifting and transfer assembly. The jacks start working, lifting the bridge and separating the bridge and the piers. Then the lifting and transfer assembly is detached from the lifting assembly.

[0078] Specifically, when the lifting assembly moves the jacking and moving assembly to the bottom, the jacking and moving assembly can be detached from the lifting assembly by a crane. The same principle applies when the support moving assembly is moved.

[0079] S3. Move the support transfer assembly onto the lifting assembly. The support transfer assembly is fixed with anchor bolts. The lifting assembly moves to a horizontal position at the top of the pier. The old support is first transported to the ground by the lifting assembly and the support transfer assembly, and then the new support is transported to the pier. Then the support transfer assembly is transported back to the ground by the lifting assembly, and the anchor bolts are removed.

[0080] S4. Control the jacks to return to their original position, the bridge will fall back down, and the replacement of the bearings will be completed;

[0081] S5. Move the lifting and transferring component and the jack onto the lifting component. The lifting component moves the jack to a position level with the top of the pier. The lifting and transferring component then clamps the jack and moves it to the ground via the lifting component.

[0082] The pick-and-place method in this setup enables the replacement of large-stroke, high-tonnage supports even in confined spaces, resulting in high replacement efficiency.

[0083] Specifically, in step S2, the specific steps are as follows:

[0084] S21. The lifting telescopic mechanism extends to the left, bringing the jack closer to the support;

[0085] S22. Fine-tune the jacks so that they are suspended between the bridge and the piers. This setting can improve the accuracy of the foreground fixed transfer.

[0086] Specifically, the fine-tuning jack includes method one and / or method two and / or method three; method one involves driving a first moving track through a lifting drive component, with a first rolling column rolling on the first moving track, and the lifting seat moving vertically under the restriction of a first limiting column, thereby achieving height adjustment of the jack; method two involves adjusting the left and right position of the jack by moving the telescopic rod left and right; and method three involves adjusting the position of the jack by rotating the support base.

[0087] S23. Lower the position of the jack from step S22 so that it is placed on the bridge pier; specifically, the same as step S22, the jack is lowered by moving the lifting seat downward.

[0088] S24. The telescopic rod moves to the right, the jack disengages from the lifting and transferring assembly, the jack starts working, lifts the bridge, and the bridge and piers separate; the lifting and transferring assembly moves to the ground through the lifting group, and the lifting and moving assembly disengages from the lifting assembly.

[0089] The jack can be quickly positioned to improve the efficiency of support replacement.

[0090] Specifically, in step S3, the support transfer assembly transfers the old support, and the specific steps are as follows:

[0091] S31. Adjust the support telescopic part and bring the support pickup part close to the old support. This setting can realize the replacement of large-stroke supports in narrow spaces.

[0092] S32. The driving body drives the rotating disc to rotate. Under the restriction of the second limiting post, the opening at the left end of the two driving support plates increases:

[0093] S33. Readjust the support telescopic part so that the old support is located between the two drive support plates for easy clamping;

[0094] S34. Drive the second moving track of the main body to move. Under the restriction of the third limiting column, the second rolling column drives the vertical moving plate to move vertically, so that the top of the vertical moving plate lifts the first section of the old support, realizing the suspension of the old support.

[0095] S35. Adjust the support telescopic part to detach the support from the pier and the bridge, and position the support on the lifting assembly.

[0096] S36. The old support is moved to the ground using the lifting assembly.

[0097] Specifically, step S3 also includes the installation of the new support, the steps of which are as follows:

[0098] S37. The bearing transfer assembly clamps the new bearing onto the lifting assembly, and the lifting assembly moves to the same height as the pier. The bearing extension part is adjusted to place the bearing pickup part at the installation position of the old bearing.

[0099] S38. The second driving body drives the second moving track to move. Under the restriction of the third limiting column, the second rolling column drives the vertical moving plate to move vertically, so that the vertical moving plate moves downward and the new support is located on the pier.

[0100] S39. Drive the rotating disc of the main body to rotate. Under the restriction of the second limit post, the opening at the left end of the two drive support plates increases. Adjust the support telescopic part again, and the new support separates from the two drive support plates to realize the installation of the new support.

[0101] This setup reduces manual labor, improves bearing replacement efficiency, and enables the replacement of large-stroke, large-tonnage bearings in confined spaces.

[0102] Specifically, in step S5, the lifting and transferring assembly transfers the jacks; the specific steps are as follows:

[0103] S51. Position the lifting and transferring component on the lifting component, and move the lifting component to the same height as the bridge pier;

[0104] S52. Fine-tune the elastic clamping component so that it is close to the bridge and the pier; the fine-tuning method is the same as step S22.

[0105] S53. Push the telescopic rod to the left so that the elastic clamp can hold the jack;

[0106] S54. The first moving track is driven by the lifting drive component, the first rolling column rolls on the first moving track, and under the restriction of the first limit column, the rising seat moves upward, thereby realizing the suspension of the jack.

[0107] S55. By extending and retracting the lifting telescopic mechanism, the jack is detached from the bridge and pier. The jack is positioned above the lifting assembly, and finally the jack and the lifting and transferring assembly are moved to the ground.

[0108] Specifically, in this replacement and delivery method, the lifting assembly moves up and down primarily through the cooperation of gears and racks.

[0109] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
