Embodiment 1
[0044] Such as Figure 1-7 The excavation and depth protection structure shown in the foundation pit includes two symmetrical support columns 2 fixedly connected to the inner wall of the bottom of the foundation pit 1 by bolts. Guard plate 3, the top of support column 2 is fixedly connected with cross bar 4 by bolt, and the top of cross bar 4 is connected with drive motor 5 by bolt, and the top of cross bar 4 is connected with protective cover 37 by bolt, and drive motor 5 Located in the protective cover 37, the drive motor 5 can be protected by the protective cover 37 to avoid damage to the drive motor 5 in the construction process. The horizontal bar 4 is longitudinally rotated and connected with a rotating shaft 7, and the outer wall of the rotating shaft 7 is fixed. The sleeve is provided with a first The bevel gear 8, the output shaft of the drive motor 5 extends into the cross bar 4 and is fixedly connected with the top of the rotating shaft 7 through a coupling. The cro...
Embodiment 2
[0052] This embodiment is a further improvement of the previous embodiment, such as Figure 1-9 As shown, a foundation pit enclosure structure that can be excavated while maintaining depth includes two symmetrical support columns 2 that are fixedly connected to the inner wall of the bottom of the foundation pit 1 by bolts. Guard plate 3, the top of support column 2 is fixedly connected with cross bar 4 by bolt, and the top of cross bar 4 is connected with drive motor 5 by bolt, and the top of cross bar 4 is connected with protective cover 37 by bolt, and drive motor 5 Located in the protective cover 37, the drive motor 5 can be protected by the protective cover 37 to avoid damage to the drive motor 5 in the construction process. The horizontal bar 4 is longitudinally rotated and connected with a rotating shaft 7, and the outer wall of the rotating shaft 7 is fixed. The sleeve is provided with a first The bevel gear 8, the output shaft of the drive motor 5 extends into the cros...
