Claims

1. An integrated self-balancing static load test load box, characterized in that: It includes a lower bearing plate (1), an upper bearing plate (2) located on the upper side of the lower bearing plate (1), and a hydraulic jack (10) fixedly connected between the lower bearing plate (1) and the upper bearing plate (2); Multiple first flexible displacement pull wire groups are fixedly connected to the lower bearing plate (1). The end of the first flexible displacement pull wire group away from the lower bearing plate (1) is the first monitoring end. When the lower bearing plate (1) moves downward, the monitoring end of the first flexible displacement pull wire group applies downward tension. Multiple second flexible displacement pull wire groups are fixedly connected to the upper bearing plate (2). The end of the second flexible displacement pull wire group away from the upper bearing plate (2) is the second monitoring end. When the upper bearing plate (2) moves upward, the monitoring end of the second flexible displacement pull wire group applies downward tension.

2. The self-balancing static load test load box of claim 1, wherein: The upper side of the lower support plate (1) is fixedly connected to a guide tube (11), and the lower side of the upper support plate (2) is fixedly connected to a guide rod (12). The guide rod (12) is slidably connected inside the guide tube (11).

3. The self-balancing static load test load box of claim 1, wherein: The first flexible displacement pull wire group includes a tension steel wire rope (4), one end of which is fixedly connected to the lower bearing plate (1), and the other end of which is the first monitoring end.

4. The integrated self-balancing static load test chamber according to claim 3, characterized in that: The second flexible displacement pull wire group includes a tension steel wire rope (5) and a reversing bracket. The reversing bracket is located between the lower bearing plate (1) and the upper bearing plate (2). The tension steel wire rope (5) passes around the reversing bracket from the lower side.

5. The self-balancing static load test load box of claim 4, wherein: The reversing bracket includes a protective shell (3), and a rotating wheel (8) is rotatably connected inside the protective shell (3). The tension steel wire rope (5) passes over the lower side of the rotating wheel (8).

6. The self-balancing static load test load box of claim 4, wherein: A flexible sleeve (6) is fixedly connected to the lower bearing plate (1) and sleeved on the outside of the tension steel wire rope (4). A flexible sleeve (7) is fixedly connected to the upper side of the upper bearing plate (2) and sleeved on the outside of the tension steel wire rope (5).

7. The self-balancing static load test load box of claim 6, wherein: Both the first flexible sleeve (6) and the second flexible sleeve (7) are corrugated pipes or rubber pipes.

8. The self-balancing static load test load box of claim 5, wherein: The protective shell (3) is a hollow structure with an opening on the upper side. A telescopic protective cover (9) located outside the tension steel wire rope (5) is fixedly connected between the upper side of the protective shell (3) and the lower side of the upper bearing plate (2).
