Description

Technical Field

[0001] This utility model relates to the field of bridge jacking technology, and in particular to a saddle-shaped support for a bridge jacking jack. Background Technology

[0002] There are five practical methods for replacing high-damping seismic isolation rubber bearings: the end-mounted integral jacking method, the flat jack method, the saddle-shaped support method, the sleeper-covered support method, and the bridge deck steel guide beam method, each with its own advantages and applicable scenarios. Among them, the saddle-shaped support method makes full use of the bridge's own supporting capacity when replacing high-damping seismic isolation rubber bearings. This method involves building a support on the cap beam, then placing jacks to lift the bearing, thereby completing the replacement. This method is not affected by riverbed conditions, water depth under the bridge, or bridge height, and has wide applicability.

[0003] However, it should be noted that the location where the jacks are placed may be prone to local deformation during the jacking process. This is because the location where the jacks are placed is a direct stress point on the entire support structure and is also a part that bears the pressure of the jacks locally. Therefore, in order to avoid affecting the stability of the entire saddle-shaped support structure in supporting the jacks due to local deformation, it is necessary to improve the effectiveness and stability of the support structure to address this issue.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a saddle-shaped support for bridge jacking. Utility Model Content

[0005] The purpose of this utility model is to provide a saddle-shaped support for a bridge lifting jack in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses a saddle-shaped support for a bridge lifting jack, comprising:

[0008] A transverse frame structure is horizontally erected above the bridge's cap beam. Two sets of bracket structures are symmetrically arranged at both ends of the transverse frame structure and on both sides of the bridge's cap beam. The bracket structures are used to support the bridge's lifting jacks.

[0009] The bracket structure includes:

[0010] A horizontal support plate, which is used to support the bridge jacking jacks;

[0011] A connecting frame structure is disposed between the horizontal support plate and the cross frame structure to connect the horizontal support plate to the end position of the cross frame structure;

[0012] And a reinforcing support mechanism, which is disposed below the horizontal support plate to reinforce and support the horizontal support plate.

[0013] Furthermore, the crossbeam structure includes a crossbeam, which is horizontally placed on the upper surface of the bridge's cap beam, and two sets of triangular brackets are symmetrically arranged at both ends of the crossbeam.

[0014] Furthermore, the tripod is a frame structure with a right-angled triangle cross section. The tripod is placed horizontally on the upper surface of the bridge cap beam, with one end fixedly connected to the cross beam, and the other end is a vertical plane aligned with the side of the bridge cap beam.

[0015] Furthermore, the connecting frame structure includes a longitudinal panel, which is arranged parallel to the vertical plane of the tripod and the side of the bridge's cap beam. The upper end of the longitudinal panel is attached to the vertical plane of the tripod and is fixedly connected to the tripod.

[0016] The horizontal support plate is fixedly connected to the longitudinal panel in a horizontal position;

[0017] Both ends of the bottom surface of the horizontal support plate are provided with triangular ribs that are fixedly connected to the longitudinal panel, and the two triangular ribs on the bottom surface of the horizontal support plate are arranged parallel to each other.

[0018] Furthermore, the reinforcing support mechanism includes a saddle plate, the two ends of which are fixedly connected between the two triangular ribs and the saddle plate is fixedly connected to the longitudinal panel.

[0019] Multiple longitudinal support ribs are connected between the upper surface of the saddle-shaped plate and the bottom surface of the horizontal support plate.

[0020] Furthermore, one end of the longitudinal support rib is fixedly connected to the longitudinal panel, and the upper part of the other end extends forward to the edge of the horizontal support plate so that the front end of the longitudinal support rib presents a bevel.

[0021] In the above technical solution, the saddle-shaped bracket for a bridge jacking jack provided by this utility model has the following beneficial effects:

[0022] This support system uses a horizontal frame structure mounted above the cover beam to provide basic support and fixation for the bracket structure. The bracket structure then supports the jacks. By improving the support structure of the bracket, the support for the jacks is made more stable, preventing deformation of the local area supporting the jacks and thus avoiding affecting the overall support effect of the support system.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-2 A saddle-shaped support for a bridge lifting jack, comprising:

[0030] The transverse frame structure is horizontally erected above the bridge's cap beam. Two sets of bracket structures are symmetrically arranged at both ends of the transverse frame structure and on both sides of the bridge's cap beam. The bracket structures are used to support the bridge jacking jacks. In other words, the transverse frame structure is erected using the cap beam as a supporting foundation, and the two sets of bracket structures are supported and fixed. This makes full use of the bridge's cap beam's own supporting capacity and retains the support characteristics of the saddle-shaped bracket. The two sets of bracket structures symmetrically arranged on both sides of the cap beam also lower the support height for the jacks, which can effectively solve the problem of the jacks being unable to be placed and used due to the limited space at the bridge jacking position.

[0031] The bracket structure includes:

[0032] Horizontal support plate 1 is used to support the bridge jacking jack.

[0033] The connecting frame structure is set between the horizontal support plate 1 and the cross frame structure to connect the horizontal support plate 1 to the end position of the cross frame structure. Therefore, the connecting frame structure mainly fixes the position of the horizontal support plate 1.

[0034] The reinforcement support mechanism is located below the horizontal support plate 1 to reinforce and support the horizontal support plate 1. The reinforcement support mechanism mainly disperses the local stress on the horizontal support plate 1, making the horizontal support plate 1 more stable when supporting the jack, and avoiding local deformation that would affect the overall stability of the support structure.

[0035] Furthermore, the crossbeam structure includes a crossbeam 2, which is horizontally placed on the upper surface of the bridge's cap beam. Two sets of triangular brackets 3 are symmetrically arranged at both ends of the crossbeam 2 to provide fixed support for the two sets of bracket structures respectively.

[0036] Furthermore, the tripod 3 is a frame structure with a right-angled triangular cross-section, resulting in high structural stability. The tripod 3 is horizontally placed on the upper surface of the bridge's cap beam, with one end fixedly connected to the crossbeam 2. The other end is a vertical plane aligned with the side of the bridge's cap beam, allowing the side of the tripod 3 adjacent to the cap beam to support the bracket structure with its entire plane. This results in a larger load-bearing surface, more stable fixation, and the stable structure of the tripod 3, providing more stable support for the bracket structure. The two tripods 3 are connected by the crossbeam 2 and mounted on the cap beam, fully utilizing the cap beam's own supporting capabilities.

[0037] Furthermore, the connecting frame structure includes a longitudinal panel 4, which is parallel to the vertical plane of the tripod 3 and the side of the bridge's cap beam. The upper end of the longitudinal panel 4 is attached to the vertical plane of the tripod 3 and is fixedly connected to the tripod 3. The longitudinal panel 4 is mainly connected to the tripod 3 and the lower end is attached to the side of the cap beam to form a larger mounting surface, which makes it more stable when installing the bracket structure. The connection between the two components can be fixed by a combination of welding and bolt connection to ensure connection stability.

[0038] The horizontal support plate 1 is fixedly connected to the longitudinal panel 4 in a horizontal state. Specifically, the horizontal support plate 1 and the longitudinal panel 4 can be connected by welding, and an auxiliary pad can be used to further fix the connection by threading to ensure the stability of the connection.

[0039] Triangular ribs 5 are fixedly connected to the longitudinal panel 4 at both ends of the bottom surface of the horizontal support plate 1. The two triangular ribs 5 on the bottom surface of the horizontal support plate 1 are arranged parallel to each other. The two triangular ribs 5 play a role in connecting and supporting the horizontal support plate 1, ensuring the stability of the horizontal support plate 1 in supporting the jack. Moreover, the triangular structure of the triangular ribs 5 is more stable as a support structure.

[0040] Furthermore, the reinforcing support mechanism includes a saddle plate 6, the two ends of which are fixedly connected between two triangular ribs 5 and the saddle plate 6 is fixedly connected to the longitudinal panel 4.

[0041] Multiple longitudinal support ribs 7 are connected between the upper surface of the saddle plate 6 and the bottom surface of the horizontal support plate 1.

[0042] Specifically, multiple longitudinal support ribs 7 are evenly distributed between the saddle plate 6 and the horizontal support plate 1. The force on the jack supported by the horizontal support plate 1 is evenly distributed to the saddle plate 6 through the multiple longitudinal support ribs 7. The saddle plate 6 is an arched plate structure that can evenly distribute the downward pressure of the horizontal support plate 1. The force is then distributed to the longitudinal panel 4 and the two triangular ribs 5 through the saddle plate 6, which effectively avoids local deformation caused by local stress on the horizontal support plate 1 and improves the stability of the jack support.

[0043] Furthermore, one end of the longitudinal support rib 7 is fixedly connected to the longitudinal panel 4, and the upper part of the other end extends forward to the edge of the horizontal support plate 1 so that the front end of the longitudinal support rib 7 presents a bevel, that is, the front end of the longitudinal support rib 7 forms a local triangular support structure, and can effectively support a whole linear area on the lower surface of the horizontal support plate 1, ensuring the support effect and stability of the horizontal support plate 1.

[0044] In summary, this support system uses a horizontal frame structure mounted above the cover beam to provide basic support and fixation for the bracket structure. The bracket structure then supports the jacks. Furthermore, by improving the support structure of the bracket, the support for the jacks is made more stable, preventing deformation of the local area supporting the jacks and thus avoiding affecting the overall support effect of the support system.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
