DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a foundation pit support monitoring device. Figure 1-4A foundation pit support monitoring device comprises a support plate 1 and a support steel 2, one side of the support steel 2 is fixedly connected to a mounting plate 3, one side of the mounting plate 3 is fixedly connected to a mounting frame 4, an axial force meter 5 is fixedly installed in the mounting frame 4, a mounting groove 41 is provided on one side of the upper end of the mounting frame 4, a slider 61 is slidably connected to the mounting groove 41, one side of the slider 61 is fixedly connected to a No. 1 protection ring 6, so that the No. 1 protection ring 6 can be slidably adjusted in the mounting groove 41, which is convenient for the use of the No. 1 protection ring 6, both sides of the upper end of the No. 1 protection ring 6 are fixedly connected to a mounting frame 7, the upper end of the mounting frame 7 is slidably connected to a mounting rod 8, the upper end of the mounting rod 8 is fixedly connected to a No. 2 protection ring 10, the No. 1 protection ring 6 and the No. 2 protection ring 10 clamp the connecting line and support and protect the connecting line;

[0023] By adopting the above technical solution, a screw 9 is threadedly connected to one side of the mounting frame 7, and one side of the screw 9 passes through the side wall of the mounting frame 7 to clamp the mounting rod 8, which is used to fix the mounting rod 8, so that the mounting rod 8 is fixed on the mounting frame 7, providing support force for the No. 2 protective ring 10.

[0024] By adopting the above technical solution, a plurality of elastic sheets 11 are fixedly connected inside the first protection ring 6 and the second protection ring 10, and one side of the elastic sheet 11 is fixedly connected to the clamping plate 12, such as Figure 4 As shown, the clamping plate 12 is arc-shaped, and several clamping plates 12 can be assembled into an annular plate. Generally, there are seven clamping plates 12, one side of which is provided with an entry port, so that the connecting line can be placed between the multiple clamping plates 12 through the entry port and clamped by the clamping plates 12.

[0025] By adopting the above technical solution, the upper and lower ends of the clamping plate 12 are both inclined surfaces, and a movable groove is provided on the side of the clamping plate 12 away from the elastic sheet 11 on the same side. The movable groove is interactively connected with the ball 13, and the movable ball 13 is arranged to make the ball 13 contact the connecting line, thereby preventing the clamping plate 12 from contacting the connecting line, reducing friction, and preventing the sliding and dragging of the connecting line and the friction and sliding of the clamping plate 12 to cause wear.

[0026] By adopting the above technical solution, openings are provided on one side of the No. 1 protective ring 6 and the No. 2 protective ring 10, so that the connecting wire can be placed into the protective ring from the opening, and a sliding groove 15 is provided on the side wall of the opening, and a baffle 14 is slidably connected in the sliding groove 15, and the baffle 14 is provided to cover the opening.

[0027] By adopting the above technical solution, one side of the baffle 14 is fixedly connected to the spring 16 , and one side of the spring 16 is fixedly connected to the side wall of the same side slide groove 15 , which is used to drive the baffle 14 to recover and allow the baffle 14 to be exposed from the slide groove 15 .

[0028] The implementation principle of a foundation pit support monitoring device according to the embodiment of the present application is as follows: after the axial force meter 5 is installed in the mounting frame 4, the connecting line is located in the mounting groove 41, and then the two baffles 14 of the No. 1 protection ring 6 are pulled from one side to make the baffles 14 enter the slide groove 15 and squeeze the spring 16 to contract, and then the connecting line is placed into the No. 1 protection ring 6 from the opening, and is placed between the clamping plates 12 in the No. 1 protection ring 6 from one side, so that the elastic sheet 11 provides thrust to the clamping plate 12, and the clamping plate 12 clamps the connecting line for support and protection. Similarly, according to the above method, the connecting line is also placed between the multiple clamping plates 12 in the No. 2 protection ring 10 and fixed, such as Figure 1 As shown, the connecting wire at the connection point between the connecting wire and the axial force gauge 5 is supported and protected to prevent the connecting wire from being squeezed when the mounting frame 4 is welded, causing the connection point between the connecting wire and the axial force gauge 5 to be squeezed or worn, resulting in damage to the connecting wire.

[0029] When installing the connecting wire, the end of the connecting wire, that is, the connecting wire connected to the axial force gauge 5, can be rolled up and placed between the No. 1 protective ring 6 and the No. 2 protective ring 10. After that, the connecting wire is placed in the No. 2 protective ring 10. This can provide a stretchable length when the connecting wire is installed and rotated, thereby avoiding direct rotation of the connecting wire, which would cause damage to the connection between the connecting wire and the axial force gauge 5.
