Description

Technical Field

[0001] This utility model relates to the field of bridge building machine technology, specifically to an integrated hydraulic support leg for an upper-bearing bridge building machine. Background Technology

[0002] Mobile formwork bridge-building machines are characterized by high construction quality, ease of operation, safety, short construction period, and low cost, and are widely used in the construction of continuous bridges or continuous rigid frame bridges. Existing mobile formwork bridge-building machines can be divided into upper-bearing and lower-bearing types, capable of constructing bridges with common cross-sections such as T-shaped, I-shaped, and box girder types. Upper-bearing bridge-building machines are bridge construction equipment where the main beam support system is located directly above the already poured bridge deck. Compared to lower-bearing bridge-building machines, they have significant advantages in construction efficiency, quality control, safety, and cost-effectiveness.

[0003] Currently, the connection between the outriggers and piers of existing upper-bearing bridge-building machines mostly requires pre-embedding connectors during pier construction to secure the bridge-building machine to the pier. This connection method necessitates pre-embedding during pier construction and requires precise positioning of the pre-embedded parts to ensure proper connection and fixation. This method is cumbersome and inconvenient, and cannot quickly connect the bridge-building machine to the pier. Furthermore, connecting with pre-embedded parts consumes a significant amount of construction time, impacting construction efficiency and thus presenting certain shortcomings. Therefore, we propose an integrated hydraulic outrigger for upper-bearing bridge-building machines. Utility Model Content

[0007] Furthermore, the base plate is provided with a clamping mechanism inside.

[0008] Furthermore, the clamping mechanism includes a slide groove, a guide rod, a sliding plate, a connecting rod, a connecting plate, a fixing plate, and a second hydraulic cylinder.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figures 1 to 7 This utility model provides a technical solution: an integrated hydraulic support leg for an upper-bearing bridge-building machine, including an upper-bearing bridge-building machine body 1, a pier 2, a support 3, and a support leg 4. The support 3 is fixedly installed at the bottom of the upper-bearing bridge-building machine body 1, and the support leg 4 is fixedly installed at the bottom of the support 3. The support leg 4 is set at the top of the pier 2, and hydraulic support mechanisms are provided on both sides of the support leg 4. Through the setting of the hydraulic support mechanism, the support leg 4 can be quickly fixed to the pier 2, improving the connection efficiency, shortening the construction cycle, and making the connection more convenient and faster.

[0028] The hydraulic support mechanism includes a side plate 5, a first adapter frame 6, a first adapter ear 7, a lever plate 8, a second adapter frame 9, a third adapter frame 10, a first hydraulic cylinder 11, a second adapter ear 12, a base plate 13, and a load-bearing plate 14. The side plate 5 is fixedly installed on both sides of the support leg 4. The first adapter frame 6 is fixedly installed on one side of the side plate 5. The first adapter ear 7 is fixedly installed on one side of the lever plate 8 and is rotatably connected to the first adapter frame 6. The second adapter frame 9 is fixedly installed on the top of the side plate 5. The third adapter frame 10 is fixedly installed on the top of one side of the lever plate 8. A second hydraulic cylinder 11 is fixedly installed at both ends. The adapter ear 12 and two second adapter ears 12 are rotatably connected to the second adapter frame 9 and the third adapter frame 10 respectively. The base plate 13 is fixedly installed on the bottom of the lever plate 8. The force plate 14 is installed on one side of the base plate 13 and contacts the outer side of the pier 2. After the first hydraulic cylinder 11 is turned on, its output end pushes the lever plate 8 to rotate around the connection part of the first adapter ear 7 and the first adapter frame 6. This allows the lever plate 8 to contact the force plate 14 on one side of the base plate 13 with both sides of the pier 2 through the lever principle. Then, the support leg 4 is fixed to the top of the pier 2, and the installation is completed. The installation is convenient and quick.

[0029] The base plate 13 is equipped with a clamping mechanism inside; the clamping mechanism can increase the firmness of the connection between the load-bearing plate 14 and the pier 2, and further improve the stability of the support leg 4 fixed on the pier 2.

[0030] The clamping mechanism includes a slide groove 15, a guide rod 16, a sliding plate 17, a connecting rod 18, a connecting plate 20, a fixed plate 21, and a second hydraulic cylinder 22. The slide groove 15 is formed inside one side of the base plate 13. The guide rod 16 is fixedly installed inside the slide groove 15. The sliding plate 17 is slidably installed outside the guide rod 16. The connecting rod 18 is rotatably installed on one side of the sliding plate 17, and the other end of the connecting rod 18 is rotatably connected to one side of the force-bearing plate 14. Two through slots 19 are formed inside one side of the base plate 13, and the connecting plate 20 is fixedly installed on the sliding plate 17. On the other side, the fixing plate 21 is fixedly installed on both sides of the base plate 13, and the second hydraulic cylinder 22 is fixedly installed on one side of the fixing plate 21. The output end of the second hydraulic cylinder 22 is fixedly connected to the connecting plate 20. After the force plate 14 is connected to both sides of the pier 2, the connecting plate 20 and the sliding plate 17 can be pushed to move by opening the second hydraulic cylinder 22. This causes the sliding plate 17 to move and push the force plate 14 to move through the connecting rod 18, which improves the firmness of the connection between the force plate 14 and both sides of the pier 2, and further improves the firmness and stability after installation.

[0031] An anti-slip plate is provided on one side of the load-bearing plate 14; the anti-slip plate increases the friction between the load-bearing plate 14 and the pier 2, and the increased friction improves the stability of the connection between the load-bearing plate 14 and the pier 2.

[0032] There are several first hydraulic cylinders 11, and these first hydraulic cylinders 11 are arranged at equal intervals; the arrangement of several first hydraulic cylinders 11 improves the stability and firmness of the installation and fixing.

[0033] There are several lever plates 8, and the lever plates 8 are arranged at equal intervals. By arranging the lever plates 8 at equal intervals with the first hydraulic cylinder 11, the uniformity of the force on the connection between the force plate 14 and the pier 2 is ensured.

[0034] The sliding plate 17 is slidably connected to the inner wall of the slide groove 15; through the slidable connection between the sliding plate 17 and the inner wall of the slide groove 15, the slide groove 15 can play a limiting role in the sliding plate 17.

[0035] The sliding plate 17 has a hole inside that mates with the guide rod 16. By having a hole inside the sliding plate 17 that mates with the guide rod 16, the sliding plate 17 and the guide rod 16 can be slidably connected, thereby improving the stability of the movement of the sliding plate 17.

[0036] Both the sliding plate 17 and the force plate 14 have hinges on one side that cooperate with the connecting rod 18. By having hinges on one side of both the sliding plate 17 and the force plate 14 that cooperate with the connecting rod 18, it is ensured that the connecting rod 18 can move and push the force plate 14 to move.

[0037] In summary, the integrated hydraulic outriggers of this top-bearing bridge-building machine, when in use, after the outrigger 4 is moved and placed on the pier 2, by opening the first hydraulic cylinder 11, its output end pushes the lever plate 8 to rotate around the connection between the first adapter ear 7 and the first adapter frame 6. This allows the lever plate 8 to contact the force plate 14 on one side of its bottom plate 13 with both sides of the pier 2 through the lever principle, thereby fixing the outrigger 4 to the top of the pier 2. After the force plate 14 is connected to both sides of the pier 2, by opening the second hydraulic cylinder 22, the connecting plate 20 and the sliding plate 17 can be displaced. This displacement of the sliding plate 17, through the connecting rod 18, pushes the force plate 14 to move, improving the firmness of the connection between the force plate 14 and both sides of the pier 2, and further improving the firmness and stability after installation.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
