[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] Example 1

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a support bracket suitable for cast-in-place bridge construction, comprising a base plate 1 and an upper plate 13. Multiple columns 2 arranged in a rectangular array are fixedly connected to the inner side of the base plate 1. Movable chambers 3 are formed on the inner side of each column 2. A first piston 4 is movably installed inside the movable chamber 3. A lifting column 5 is fixedly connected to the top of the first piston 4. The top of the lifting column 5 is spherical. The movable chambers 3 inside the multiple columns 2 are interconnected via oil pipes 6. A straight-through valve is provided at one end of each oil pipe near the multiple columns 2. The oil pipes 6 are high-pressure pipes. An oil tank 7 is fixedly connected to the bottom surface of the base plate 1. The oil tank 7 contains liquid... The hydraulic system is equipped with a hydraulic pump 8 and a check valve 9 fixedly installed on one side of the bottom of the base plate 1. The hydraulic pump 8 is manually driven. One end of the oil tank 7 is fixedly connected to a connecting pipe, the middle of which is connected to both the hydraulic pump 8 and the check valve 9. The other end of the connecting pipe is connected to the oil pipe 6. The other side of the bottom of the base plate 1 is fixedly connected to a return valve 10. A connecting pipe is fixedly connected through the inside of the return valve 10. The two ends of the connecting pipe are fixedly connected to the oil pipe 6 and the oil tank 7, respectively. Rotating rods 11 are rotatably connected to the inside of both the hydraulic pump 8 and the return valve 10. Two support blocks 12 are fixedly connected to the bottom of the base plate 1, and the two rotating rods 11 are respectively connected to the two support blocks 12. The upper plate 13 is rotatably connected, and multiple grooves 14 are provided at the bottom end. The grooves 14 are spherical grooves, and the multiple grooves 14 are adapted to the tops of multiple lifting columns 5. The hydraulic oil inside the oil tank 7 is injected into the oil pipe 6 by the hydraulic pump 8. Through the oil pipe 6, the oil can enter the inside of multiple columns 2. The oil inside the movable chamber 3 of the column 2 can push the first piston 4 to move upward. Thus, not only can the height of the device be adjusted according to the usage requirements, but also the device can have an automatic leveling function by utilizing the fluidity of the oil and the property of equal pressure throughout the liquid. Before use, ensure that the return valve 10 is in the closed state. Then, by manually rotating the lever 11 at one end of the hydraulic pump 8, the hydraulic pump 8 can be driven to run, so that the oil inside the oil tank 7 can enter the movable chamber 3. The increase of oil inside the movable chamber 3 can push the first piston 4 upward, thereby forcing the lifting column 5 to extend upward. The one-way valve 9 can prevent the oil from flowing back. By opening the return valve 10, the oil can flow back, thereby causing the lifting column 5 to retract downward. The height of the device can be adjusted by raising and lowering the lifting column 5. By closing multiple straight-through valves, the oil inside multiple movable chambers 3 can be blocked and cannot flow, thus enabling load-bearing.

The spring 18 can absorb the impact when the bracket 26 is hit. The connection channel 23, movable plate 24, return hole 25 and the oil inside the fixed cylinder 17 are adapted to eliminate the shock wave, thereby achieving a shock absorption effect and protecting the bridge cast at the upper end of the bracket 26. When the bracket 26 is subjected to pressure or impact from above, the impact will be transmitted downward through the load-bearing column 19, thereby compressing the spring 18 and causing the oil inside the fixed cylinder 17 to flow into the floating cavity 20. Since the movable plate 24 can move, the oil can flow quickly from the inside of the movable plate 24 into the floating cavity 20. When the spring 18 absorbs the impact, it will rebound. At this time, the movable plate 24 blocks the connection channel 23, so that the oil can only flow back through the return hole 25, so that the load-bearing column 19 can descend quickly and rise slowly, thereby absorbing the impact.
