[0028] Moreover, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model

[0029] The utility model provides a foundation pit support structure, aiming to solve the problems in the prior art solutions that the support rod is not convenient to be removed from the top of the cross plate, resulting in inconvenient folding and storage of the vertical plate, and the number of turns of rotation of the two threaded rods is not convenient to be kept consistent, resulting in deviation of the moving distances of the two threaded rods, resulting in unbalanced support of the vertical plate by the two support rods and affecting the support effect on the foundation pit.

[0030] As Figures 1-6 shown, a foundation pit support structure provided by an embodiment of the utility model includes a bottom plate 1 and a support plate 2. A support mechanism 3 is arranged on the left side of the support plate 2, and the number of the support mechanisms 3 is three. A top rod 5 is arranged on the top of the bottom plate 1, and a top plate 8 is movably arranged on the top of the bottom plate 1;

[0031] The support mechanism 3 includes a T-shaped block 301, a first rotating frame 302, a support rod 303 and a second rotating frame 304. The right side of the first rotating frame 302 is fixedly connected with the left side of the T-shaped block 301. One side of the support rod 303 close to the first rotating frame 302 is rotatably connected inside the first rotating frame 302, and one side of the support rod 303 close to the second rotating frame 304 is rotatably connected inside the second rotating frame 304. The bottom of the second rotating frame 304 is in movable contact with the top of the bottom plate 1.

[0032] In the technical solution of the present utility model, by moving the bottom plate 1 and the support plate 2 to the position where the foundation pit needs to be supported, the limit cone 4 is inserted into the ground. At this time, the limit cone 4 can limit the bottom plate 1. Then, the ejector rod 5 is rotated. The ejector rod 5 is threadedly connected to the inside of the fixed block 6. When the ejector rod 5 rotates, the ejector rod 5 can move to the right to push the top frame 7 and the top plate 8 to the right. At this time, when the slider 12 moves inside the chute 15, the movement of the top plate 8 can be made more stable, so that the right side of the top plate 8 is in close contact with the left side of the second anti-slip cone 10, and the second rotating frame 304 can be stably pushed to the right. At this time, the support rod 303 rotates inside the first rotating frame 302 and the second rotating frame 304, and the support plate 2 can be rotated and supported to an appropriate angle, which is convenient for supporting the foundation pit. At this time, the first anti-slip cone 13 will be in close contact with the inner wall of the T-shaped groove 16, so that the first rotating frame 302 is stably connected to the support plate 2. By rotating the ejector rod 5 in the reverse direction, the top plate 8 can be separated from the second anti-slip cone 10. Then, by holding the handle 9 and moving backward, the first rotating frame 302 can drive the T-shaped block 301 to move backward until it is separated from the T-shaped groove 16, which is convenient for removing the support rod 303 from the top of the bottom plate 1. Then, the support plate 2 can be folded to the left for storage, which is convenient for moving and transporting the bottom plate 1 and the support plate 2. The support plate 2 is rotatably connected inside the third rotating frame 14, so that the support plate 2 can rotate. By rotating one ejector rod 5, the top plate 8 can move horizontally to the right to push the three second rotating frames 304 to the right at the same time, so that the three second rotating frames 304 and the support rods 303 are evenly stressed, thereby providing balanced support for the support plate 2, avoiding the problems in the prior art solutions that the support rods are inconvenient to be removed from the top of the cross plate, resulting in inconvenient folding and storage of the vertical plate, and the number of turns of the two threaded rods is inconvenient to be kept consistent, resulting in a deviation in the moving distance of the two threaded rods, resulting in unbalanced support of the two support rods for the vertical plate and affecting the support effect on the foundation pit.
