A foundation pit slope protection structure Technical Field

[0001] This utility model relates to the field of foundation pit slope protection technology, specifically a foundation pit slope protection structure. Background Technology

[0002] A foundation pit is an underground cavity excavated during building construction. After the foundation pit is excavated to a certain depth, the slope of the foundation pit needs to be protected to ensure the safety of construction workers and prevent soil collapse. Foundation pit slope protection is an important safety measure in building construction.

[0003] Currently used foundation pit slope protection structures cannot be expanded or contracted according to the overall area of ​​the foundation pit slope when intercepting and protecting the slope. When the remaining area at the corner of the foundation pit slope is small, it is not convenient to fix the protection structure to the slope for protection. This is not conducive to adaptive adjustment and use in different foundation pits. Therefore, we propose a foundation pit slope protection structure to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a foundation pit slope protection structure to solve the problems mentioned in the background art, such as the inability to expand and contract according to the overall area of ​​the foundation pit slope, the inability to conveniently fix the protection structure to the slope for protection when the remaining area at the corner of the foundation pit slope is small, and the difficulty in adapting and adjusting its use in different foundation pits.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foundation pit slope protection structure, including a mounting base, a plug rod installed at the lower end of the mounting base, a screw rod connected inside the mounting base, a moving block threadedly connected to the outer side of the screw rod, an adjusting rod hinged to the side of the moving block, and a support rod hinged to the lower end of the adjusting rod.

[0006] A rotating shaft is connected to the side of the mounting base, and the rotating shaft is connected to the lower end of the support rod.

[0007] A movable seat is fitted on the outer side of the support rod, and a bolt is threaded onto the movable seat. A threaded hole is opened on the side of the support rod. A secondary stop rod is hinged to the end of the movable seat. A main stop rod is hinged to the end of the secondary stop rod away from the movable seat. The upper end of the main stop rod is hinged to the support rod, and the lower end of the main stop rod is hinged to a connecting rod.

[0008] Preferably, the movable block is slidably connected to the mounting base through the mounting base, and the mounting base has through slots with openings on the left and right sides.

[0009] Preferably, the support rod forms a rotating structure with the mounting base via a rotating shaft, and the lower end of the insertion rod connected to the lower side of the mounting base is conical.

[0010] Preferably, the movable seat and the support rod form an up-and-down sliding structure, the movable seat and the support rod are fixed together by bolts, and the support rod has threaded holes distributed at equal intervals.

[0011] Preferably, the main stop rods are movably connected by connecting rods, and the connecting rods are vertically distributed.

[0012] Preferably, both the auxiliary stop and the main stop are inclined and symmetrical about the longitudinal centerline of the support rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The slope protection structure of the foundation pit can drive the main stop and the auxiliary stop to rotate by moving the driving connecting rod, so as to realize the expansion and contraction of the main stop and the auxiliary stop. The protection structure can be expanded according to the actual area to be used in the foundation pit, adapting to different foundation pits. After the protection structure is folded, it is easy to carry.

[0015] (2) The foundation pit slope protection structure can control the movement of the moving block by controlling the rotation of the screw, thereby driving the adjustment rod to rotate, and then pushing the support rod to rotate, adjusting the angle of the support rod so that the unfolded main stop and auxiliary stop can effectively fit the foundation pit slope and intercept and protect the foundation pit slope.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please refer to Figures 1-6. This utility model provides the following technical solution: a foundation pit slope protection structure, including a mounting base 1, a plug rod 2 installed at the lower end of the mounting base 1, a screw rod 3 connected inside the mounting base 1, a moving block 4 threadedly connected to the outer side of the screw rod 3, an adjusting rod 5 hinged to the side of the moving block 4, and a support rod 6 hinged to the lower end of the adjusting rod 5.

[0025] Furthermore, the movable block 4 is slidably connected to the mounting base 1 through the mounting base 1. The mounting base 1 has through slots with openings on the left and right sides, and the movable block 4 can be kept vertically moved by rotating the drive screw 3.

[0026] A rotating shaft 7 is connected to the side of the mounting base 1, and the rotating shaft 7 is connected to the lower end of the support rod 6.

[0027] Furthermore, the support rod 6 forms a rotating structure with the mounting base 1 through the rotating shaft 7. The lower end of the plug rod 2 connected to the lower side of the mounting base 1 is conical, which can be used to fix the mounting base 1. The angle of the support rod 6 can be adjusted to adapt to the angle of the slope and fit the slope.

[0028] A movable seat 8 is fitted on the outer side of the support rod 6. A bolt 9 is threadedly connected to the movable seat 8. A threaded hole 10 is opened on the side of the support rod 6. A secondary stop rod 11 is hinged to the end of the movable seat 8. A main stop rod 12 is hinged to the end of the secondary stop rod 11 away from the movable seat 8. The upper end of the main stop rod 12 is hinged to the support rod 6. A connecting rod 13 is hinged to the lower end of the main stop rod 12.

[0029] Furthermore, the movable seat 8 and the support rod 6 form an up-and-down sliding structure. The movable seat 8 and the support rod 6 are fixed together by bolts 9. The support rod 6 has threaded holes 10 distributed at equal intervals to ensure that the main stop rod 12 and the auxiliary stop rod 11 can rotate smoothly, realize the extension and retraction of the main stop rod 12 and the auxiliary stop rod 11, and fix the main stop rod 12 and the auxiliary stop rod 11 by fixing the movable seat 8.

[0030] Furthermore, the main stop rods 12 are movably connected by connecting rods 13, which are vertically distributed to enable synchronous rotation of the main stop rods 12 with spacing.

[0031] Furthermore, both the auxiliary stop bar 11 and the main stop bar 12 are inclined and symmetrical about the longitudinal center line of the support bar 6, so that the main stop bar 12 and the auxiliary stop bar 11 can be used to shield and protect the slope.

[0032] Specifically, when using this foundation pit slope protection structure, the entire device is carried to the foundation pit for use. First, the protection structure is unfolded according to the area to be used. The connecting rod 13 is pulled away from the support rod 6, causing the connecting rod 13 to drive the hinged main stop rod 12 to rotate. The other end of the main stop rod 12 rotates on the hinged support rod 6, causing the main stop rod 12 to gradually rotate and unfold. When the main stop rod 12 rotates, it can drive the side-hinged auxiliary stop rod 11 to rotate. The other end of the auxiliary stop rod 11 rotates on the hinged movable seat 8, and the movable seat 8 slides on the support rod 6 under force. The movable seat 8 slides upward under force, allowing the main stop rod 12 and the auxiliary stop rod 11 to rotate smoothly. After unfolding to the required size, bolts 9 can be threaded through the movable seat 8 and connected to the corresponding threaded hole 10 to fix the movable seat 8, stabilizing the unfolding of the main stop rod 12 and the auxiliary stop rod 11. Insert the insertion rod 2 to a position close to the foundation pit slope, fix the mounting seat 1 in the foundation pit, rotate the screw 3, the screw 3 drives the outer threaded movable block 4 to move downward, the movable block 4 pushes the hinged adjusting rod 5 to rotate, the adjusting rod 5 pushes the lower hinged support rod 6, so that the support rod 6 rotates on the mounting seat 1 through the rotating shaft 7, and the support rod 6 gradually tilts, so that the unfolded main stop rod 12 and auxiliary stop rod 11 fit against the foundation pit slope, intercepting and protecting the foundation pit slope;

[0033] After use, the screw 3 can be rotated in the opposite direction to move the moving block 4 upward, pull the adjusting rod 5 to rotate in the opposite direction, thereby driving the support rod 6 to rotate in the opposite direction and reset. Rotate the support rod 6 to the vertical position, remove the bolt 9, release the fixation of the moving seat 8, and then push the connecting rod 13 to move towards the support rod 6, driving the main stop rod 12 and the auxiliary stop rod 11 to rotate in the opposite direction and fold, reducing the area of ​​the entire protective structure and making it easier to carry. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
