A folding tie rod replacement bracket

Abstract

This utility model discloses a foldable tie rod replacement bracket, including an n-shaped bracket with bases fixedly connected to both ends of the bottom of the n-shaped bracket. When idle, the first cylinder, rotating shaft, and U-shaped clamping plate are folded and placed inside the I-shaped frame. During operation, rotating the rotating plate 180 degrees allows the first cylinder, rotating shaft, and U-shaped clamping plate to be moved out of the I-shaped frame. By setting a second cylinder and clamping blocks, the columns connected to both ends of the tie rod can be clamped and fixed. The third cylinder can drive the lifting plate to move upward. The top surface of the lifting plate contacts the bottom surface of the tie rod to be replaced, which can provide support for the tie rod. The rotating load-bearing plate can quickly adjust the angle of the top surface of the lifting plate to quickly adapt to tie rods of different angles. After the tie rod is replaced, simply close the second cylinder and fold the first cylinder, rotating shaft, and U-shaped clamping plate to remove the entire bracket from under the tie rod.

Description

Technical Field

[0001] This utility model relates to the field of tie rod technology, and in particular to a foldable tie rod replacement bracket. Background Technology

[0002] Tie rods are tension rods in arch bridges that bear the horizontal thrust at the arch end. They prevent the arch end supports from generating horizontal thrust, thus creating a thrust-free arch. Based on the comparison of the stiffness of the tie rods and the arch ribs, they can be divided into rigid tie rods and flexible tie rods. Tie rods are the core components of thrust-free arch bridges. By bearing the horizontal thrust at the arch end, they prevent the supports from generating horizontal reaction forces, forming a self-balancing system. In engineering practice, tie rods are often constructed using materials such as prestressed steel strands and concrete, and the internal forces of the structure are adjusted through tensioning processes.

[0003] The following problems exist: Before replacing the damaged tie rods, in order to ensure the stability of the entire bridge structure, workers usually need to temporarily reinforce the column structures connected to both ends of the tie rods. This temporary reinforcement is to prevent any accidents during the replacement process and ensure the safety of the entire bridge. After the tie rod replacement is completed, workers also need to remove the previously implemented temporary reinforcement structure to restore the bridge to its original state. However, this entire process not only consumes a lot of workers' time, but also reduces the efficiency of tie rod replacement to a certain extent, thus affecting the progress of the entire bridge maintenance project.

A third cylinder is fixedly connected to the center of the top of the I-frame. A U-shaped support plate is fixedly connected to the top of the third cylinder. Horizontal bars are fixedly connected to both sides of the inner wall of the U-shaped support plate. A load-bearing plate is rotatably connected to the outer wall of the horizontal bars. A lifting plate is fixedly connected to the top of the load-bearing plate.

[0007] As a further description of the above technical solution:

[0008] The top center of the n-shaped bracket has a frame that runs through it, and the inner wall of the frame is slidably connected to the outer wall of the square column.

[0009] As a further description of the above technical solution:

[0010] Both sides of the front end of the I-shaped frame are perforated with baffles, and both ends of the inner wall of the I-shaped frame are fixedly connected with shafts. The outer walls of the shafts are rotatably connected with rotating plates.

[0011] As a further description of the above technical solution:

[0012] Both sets of rotating plates are fixedly connected to a first cylinder on their opposite sides. The movable end of each first cylinder is fixedly connected to a rotating shaft, and the movable end of each rotating shaft is rotatably connected to a U-shaped clamping plate.

[0013] As a further description of the above technical solution:

[0014] The inner walls of the U-shaped clamping plate are each penetrated by a second cylinder, and the movable ends of the second cylinders are fixedly connected to clamping blocks.

[0015] As a further description of the above technical solution:

[0016] Both ends of the platform are provided with square holes that extend vertically through each other, and one end of the outer wall of the second cylinder can pass through the square holes.

[0017] As a further description of the above technical solution:

[0018] The front end of the U-shaped support plate is provided with a threaded hole, and the inner wall of the threaded hole is threaded with a locking bolt.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] (1) When idle, the first cylinder, the rotating shaft and the U-shaped clamping plate are folded and placed inside the I-frame. When working, the rotating plate is rotated 180 degrees, and the first cylinder, the rotating shaft and the U-shaped clamping plate can be moved out of the I-frame. By setting the second cylinder and the clamping block, the columns connected to both ends of the tie rod can be clamped and fixed. The third cylinder can drive the lifting plate to move upward. The top surface of the lifting plate contacts the bottom surface of the tie rod that needs to be replaced, which can support the tie rod. The rotating load-bearing plate can quickly adjust the angle of the top surface of the lifting plate, which can quickly adapt to tie rods of different angles. After the tie rod is replaced, the second cylinder only needs to be closed, and the first cylinder, the rotating shaft and the U-shaped clamping plate can be folded to remove the entire bracket from under the tie rod. The whole process not only saves the time of the staff, but also improves the replacement efficiency of the tie rod.

[0021] (2) By setting locking bolts, the load-bearing plate can be fixed. At this time, the lifting plate after the angle adjustment cannot be rotated. Then the damaged tie rod can be removed, and the replacement tie rod can be placed on the lifting plate with the angle fixed. The whole process does not require the staff to remeasure the position of the tie rod. When the square column moves up and down, the adjustment range of the lifting plate height can be expanded.

[0029] Reference Figure 1-2This utility model provides an embodiment of a folding tie rod replacement bracket, including an n-shaped bracket 1. Bases 2 are fixedly connected to both ends of the bottom of the n-shaped bracket 1. Anti-slip protrusions are installed on the bottom surface of the bases 2 to prevent the bracket from sliding on the ground. Horizontal plates 3 are fixedly connected to the bottom ends of both sides of the inner wall of the n-shaped bracket 1. A through-hole is opened in the horizontal plate 3, and a forward / reverse motor 4 is fixedly connected to the inner wall of the hole. The movable end of the forward / reverse motor 4 is vertically upward. A threaded column 5 is rotatably connected to the movable end of the forward / reverse motor 4. A threaded sleeve 6 is threadedly connected to the outer wall of the threaded column 5. A square column 7 is fixedly connected to the outer wall of the threaded sleeve 6. When the forward / reverse motor 4 rotates with the threaded column 5, the threaded sleeve 6 can move up and down on the outer wall of the rotating threaded column 5, and the square column 7 will also slide up and down along with it.

[0030] A frame 8 runs through the center of the top of the n-shaped bracket 1. The inner wall of the frame 8 is slidably connected to the outer wall of the square column 7. By setting the frame 8, the square column 7 can be limited, thereby preventing the square column 7 from rotating. A column 9 is fixedly connected to the top of the square column 7. A platform 10 is fixedly connected to the top of the column 9. An I-shaped frame 11 is fixedly connected to the top of the platform 10. Square through holes are opened on both sides of the front end of the I-shaped frame 11, and baffles 12 are fitted into the inner walls of the square through holes. A shaft 13 is fixedly connected to both ends of the inner wall of the I-shaped frame 11. A rotating plate 14 is rotatably connected to the outer wall of the shaft 13. By setting the baffles 12, the rotating plate 14 can be fixed after rotation. A first cylinder 15 is fixedly connected to the opposite face of the two sets of rotating plates 14. A rotating shaft 1 is fixedly connected to the movable end of the first cylinder 15. 6. The movable ends of the rotating shaft 16 are rotatably connected to U-shaped clamping plates 17. When idle, the first cylinder 15, rotating shaft 16 and U-shaped clamping plates 17 are folded and placed inside the I-frame 11. When working, rotating the rotating plate 14 by 180 degrees can remove the first cylinder 15, rotating shaft 16 and U-shaped clamping plates 17 from the I-frame 11. The inner walls of the U-shaped clamping plates 17 are penetrated by second cylinders 18 on both sides. The movable ends of the second cylinders 18 are fixedly connected to clamping blocks 19. By setting the rotating shaft 16, the angle of the U-shaped clamping plates 17 can be adjusted. By setting the second cylinders 18 and clamping blocks 19, the columns connected to both ends of the tie rod can be clamped and fixed. The two ends of the platform 10 are provided with square holes 20 that pass through vertically. One end of the outer wall of the second cylinder 18 can pass through the square hole 20.

[0031] A third cylinder 21 is fixedly connected to the top center of the I-frame 11. A U-shaped support plate 22 is fixedly connected to the top of the third cylinder 21. Crossbars 23 are fixedly connected to both sides of the inner wall of the U-shaped support plate 22. A load-bearing plate 24 is rotatably connected to the outer wall of the crossbars 23. A lifting plate 25 is fixedly connected to the top of the load-bearing plate 24. A threaded hole is opened at the front end of the U-shaped support plate 22, and a locking bolt 26 is threaded into the inner wall of the threaded hole. The third cylinder 21 can drive the lifting plate 25 to move upward. The top surface of the lifting plate 25 contacts the bottom surface of the tie rod that needs to be replaced. The rotating load-bearing plate 24 can quickly adjust the angle of the top surface of the lifting plate 25, adapting quickly to loads at different angles. By setting the locking bolt 26, the load-bearing plate 24 can be fixed, at which point the lifting plate 25 after angle adjustment cannot rotate. Then, the damaged load can be removed, and the replacement load can be placed on the lifting plate 25 with the angle fixed. The whole process does not require the staff to remeasure the position of the load. When the square column 7 moves up and down, the adjustment range of the height of the lifting plate 25 can be expanded.
