[0034] The following is combined with Figure 1-2 This application is described in further detail.

[0035] The embodiment of the present application discloses a municipal road foundation pit safety protection device.

[0036] Reference Figure 1 and Figure 2 A municipal road foundation pit safety protection device includes a plurality of protection units connected in sequence, wherein the protection unit includes a column 1 and a baffle 2 whose one end is detachably connected to the column 1, at least two ear plates 3 are arranged at both ends of the baffle 2, one end of the ear plate 3 is fixedly connected to the baffle 2, and the other end is rotatably and detachably connected to the column 1.

[0037] By utilizing the rotational connection between the ear plate 3 and the column 1, during the process of adjusting the protective device, force can be applied to the baffle plate 2 to cause the baffle plate 2 to rotate relative to the column 1, thereby changing the angle between two adjacent baffle plates 2, thereby improving the technical problem in the prior art that the shape of the guardrail cannot be quickly and adaptively changed according to changes in the shape of the foundation pit.

[0038] When used, the protective unit can be formed by a plurality of columns 1 and a plurality of baffles 2 to form a ring-shaped enclosure type protective device, or a plurality of columns 1 and a plurality of baffles 2 can be connected in sequence to form a straight or curved linear type protective device. Specifically, a column 1-baffle 2-column-baffle 2 sequentially connected structure is adopted.

[0039] During installation, the bottom end of the column 1 can be fixed to the ground by anchor bolts to maintain stability.

[0040] The column 1 includes a base 11 and a cylindrical rod 12 whose lower end is fixedly connected to the base 11 , and the other end of the ear plate 3 is rotatably connected to the cylindrical rod 12 .

[0041] A plurality of through holes are evenly distributed on the circumference of the base 11 , so that anchor bolts can pass through to achieve fixed installation of the base 11 .

[0042] The cylindrical rod 12 can be made of a steel pipe and welded to the base 11. Thereby, the cylindrical rod 12 and the ear plate 3 are rotatably connected, and the ear plate 3 can be slid upwards from the top of the cylindrical rod 12 and taken out.

[0043] The baffle 2 can be made of iron sheet, or can be composed of a frame structure made of steel wire mesh and steel plate.

[0044] Reference Figure 1 and Figure 2 An external thread is formed on the outer side of the cylindrical rod 12, and a positioning platform 5 is threadedly connected thereto, and the ear plate 3 connected to the same column 1 and located at the bottom abuts against the upper side of the positioning platform 5. The positioning platform 5 supports the ear plate 3 and indirectly supports the baffle 2, so that the baffle 2 is off the ground. Before supporting, the height of the positioning platform 5 can be adjusted by rotating.

[0045] A gasket 6 rotatably connected to the column 1 is provided between the positioning platform 5 and the ear plate 3. The gasket 6 forms a partition between the ear plate 3 and the positioning platform 5 to prevent the positioning platform 5 from rotating relative to the column 1 and changing the height of the positioning platform 5 due to the gravity of the baffle 2 when the baffle 2 is rotated.

[0046] As a parallel manner of the above embodiment, the positioning platform 5 may also be fixedly connected to the cylindrical rod 12 by welding, but in this case, the height of the positioning platform 5 cannot be adjusted.

[0047] Reference Figure 1 and Figure 2 The ear plate 3 includes a connecting plate 31 and a connecting ring 32. One end of the connecting plate 31 is fixedly connected to the baffle 2. The connecting ring 32 is fixedly connected to the other end of the connecting plate 31 and is rotatably and slidably connected to the column 1. The vertical height of the connecting ring 32 relative to the column 1 is changed by vertical sliding.

[0048] In this embodiment, the connecting ring 32 is a ring-shaped structure.

[0049] In the parallel solution, the connection ring 32 opens in a direction away from the connection plate 31 to form a column inlet 321. The connection ring 32 can be deformed under pressure. Specifically, the connection ring 32 can be made of steel plate, rubber or other materials.

[0050] The column 1 enters and exits the connecting ring 32 through the column inlet 321, so that the ear plate 3 can be connected with the column 1 by horizontal movement, and can be installed and removed, which is convenient for installation and removal.

[0051] The opening width of the column inlet 321 is smaller than the diameter of the cylindrical rod 12 of the column 1 to ensure that the cylindrical rod 12 will not be separated from each other when the connecting ring 32 is clamped on the cylindrical rod 12.

[0052] Both ends of the connecting ring 32 located at the column inlet 321 are fixed with inclined guide plates 322, and the two guide plates 322 are away from the connecting ring 32 and inclined away from each other. In order to use the two guide plates 322 to form a guiding effect, the column 1 is guided into the connecting ring 32.

[0053] Reference Figure 1 and Figure 2 A bolt 4 is provided at one end of the connecting plate 31 of the ear plate 3, and one end of the ear plate 3 is detachably connected to the baffle plate 2 through the bolt 4. The detachable connection between the ear plate 3 and the baffle plate 2 is realized through the bolt 4, so that the replacement of the ear plate 3 and / or the baffle plate 2 is convenient.

[0054] Both ends of the baffle plate 2 are vertically spaced apart with a plurality of positioning holes 21 , and one end of the ear plate 3 is penetrated with a plug hole 311 , and the bolt 4 is simultaneously passed through the connected positioning holes 21 and the plug hole 311 .

[0055] By inserting bolts 4 through positioning holes 21 at different heights, the height of the ear plate 3 relative to the baffle 2 can be adjusted to adjust the relative positions of the adjacent ear plates 3 respectively connected to two adjacent baffles 2 so that the two do not overlap and are easy to install.

[0056] During the specific installation, first fix the column 1 to the ground; then insert one of the baffles 2 with the ear plate 3 fixed by bolts 4 into the cylindrical rod 12 of the column 1 from the horizontal direction, so that the lowermost ear plate 3 of the baffle 2 abuts against the top of the gasket 6; then adjust the height of the ear plates 3 below and above the other baffle 2, and insert the baffle 2 into the cylindrical rod 12 of the column 1 from the horizontal direction, so that the lower ear plate 3 of the other baffle 2 abuts against the upper side of the ear plate 3 below the first baffle 2 to form a support.

[0057] When the angle between the two baffles 2 needs to be adjusted, first separate the ear plate 3 at the other end of the baffle 2 to be rotated from the column 1 (or directly unscrew the bolt 4 of the ear plate 3 at the other end), and then rotate the baffle 2.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
