Description

Technical Field

[0001] This utility model relates to the field of foundation pit technology, specifically a foundation pit safety protection device for highway engineering. Background Technology

[0002] In highway construction, safety protection devices need to be set up around the foundation pit to prevent people, vehicles or debris from falling in and to ensure construction safety. Existing foundation pit protection mostly adopts fixed guardrails or fences.

[0003] Fixed guardrails or fences are mostly rigid structures, and their size and shape are not adjustable. Adjustable ones are mostly lateral. When encountering zigzag or curved foundation pit slopes, they cannot effectively protect them. For irregular foundation pits, it is often necessary to customize protective devices of specific sizes or use multiple standard parts to splice together to achieve the protective effect. Therefore, we propose a foundation pit safety protection device for highway engineering to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection device for foundation pits in highway engineering, so as to solve the problems mentioned in the background art.

[0005] By adopting the above technical solution, the first socket can be quickly fixed or loosened by tightening the locking bolt, and the connecting rod can be flexibly adjusted in the X and Y axis directions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 - Figure 5This utility model provides a technical solution: a safety protection device for foundation pits in highway engineering, including two sets of support seats 1, with N connecting rods 2 arranged between the two sets of support seats 1. Each support seat 1 has a connecting seat 11 at its upper and lower ends, and the connecting seat 11 is rotatably connected to the outer peripheral wall of the connecting rod 2. Each adjacent connecting rod 2 is provided with an upper protective frame group 3 and a lower protective frame group 4. The upper protective frame group 3 includes a first upper rotating rod 31 and a second upper rotating rod 32, with the ends of the first upper rotating rod 31 and the second upper rotating rod 32 rotatably connected, and the other ends of the first upper rotating rod 31 and the second upper rotating rod 32 are respectively rotatably connected to the adjacent connecting rod 2.

Both ends of the first lower rotating rod 41 and the second lower rotating rod 42 are rotatably connected to the two adjacent connecting rods 2.

[0021] The first upper rotating rod 31 and the second upper rotating rod 32 form a V-shaped protective structure to prevent personnel or objects from falling into the pit. The first lower rotating rod 41 and the second lower rotating rod 42 form an X-shaped structure to enhance the overall rigidity. At the same time, the connecting rod 2 can rotate with the upper protective frame group 3 and the lower protective frame group 4 to achieve adjustment in the X and Y directions. The horizontal X-axis spacing of the connecting rod 2 is controlled by adjusting the lower X-shaped lower protective frame group 4 and the upper V-shaped upper protective frame group 3. The longitudinal Y-axis angle is adjusted by the rotatable socket and rotating seat, so that the device can flexibly adapt to the protection needs of straight, broken, and even certain arc foundation pit slopes.

[0022] N connecting rods 2 consist of a front connecting rod 2a, at least one intermediate connecting rod 2b, and an end connecting rod 2c. Two sets of support seats 1 are connected to the front connecting rod 2a and the end connecting rod 2c, respectively.

[0023] With the extension of multiple intermediate connecting rods 2b, it is suitable for foundation pit protection at different distances.

[0024] A first upper rotating seat 21 and a second upper rotating seat 22 are rotatably connected to the connecting rod 2, and the first upper rotating seat 21 and the second upper rotating seat 22 are located at the top of the connecting rod 2.

[0025] The first upper rotating rod 31 on the upper protective frame group 3 is rotatably connected to the first upper rotating seat 21 on the connecting rod 2, and the second upper rotating rod 32 on the upper protective frame group 3 is rotatably connected to the second upper rotating seat 22 on the adjacent connecting rod 2.

[0026] The adjacent connecting rods 2 are connected by the first upper rotating rod 31 and the second upper rotating rod 32. When the distance between two adjacent connecting rods 2 is adjusted, the first upper rotating rod 31 and the second upper rotating rod 32 rotate and unfold, and protection is provided under the action of the first upper rotating rod 31 and the second upper rotating rod 32. Furthermore, the upper protective frame assembly 3 can rotate on two adjacent connecting rods 2, thereby allowing the two adjacent connecting rods 2 to rotate through the upper protective frame assembly 3, adjusting the X-axis and Y-axis positions of the two connecting rods 2.

[0027] A first lower rotating seat 25 and a second lower rotating seat 26 are rotatably connected to the connecting rod 2, and the first lower rotating seat 25 and the second lower rotating seat 26 are located at the bottom end of the connecting rod 2.

[0028] The connecting rod 2 is fitted with a first socket 23 and a second socket 24. The first socket 23 and the second socket 24 are rotatably connected and are located at the middle end of the connecting rod 2.

[0031] By rotating the locking bolt 231, the locking bolt 231 is made to abut or separate from the connecting rod 2, thereby controlling the fixing or loosening of the first socket 23 and the connecting rod 2, and realizing the flexible adjustment of the connecting rod 2 in the X-axis and Y-axis directions; When the first socket 23 is released from the connecting rod 2, the first socket 23 can be adjusted to move on the outer peripheral wall of the connecting rod 2, thereby controlling the unfolding of the first lower rotating rod 41 and the second lower rotating rod 42, thereby adjusting the X-axis position of the adjacent connecting rod 2, and thus adjusting the distance between the adjacent connecting rod 2. When the first set of connectors 23 is released from the connecting rod 2, the second set of connectors 24 and the first set of connectors 23 can be adjusted to rotate, thereby driving the first lower rotating rod 41 and the second lower rotating rod 42 to rotate, adjusting the Y-axis position of the adjacent connecting rod 2. By adjusting the XY-axis position of the adjacent connecting rod 2, the connecting rod 2 can be easily adjusted to the specified position, and then adjusted according to the shape of the foundation pit.

[0032] The side of the support base 1 is provided with mounting holes. When two sets of support bases 1 are connected, the two connected support bases 1 can be fixed by using the mounting holes and bolts.
