Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit monitoring points, in particular to a turnover installation structure of foundation pit monitoring points. Background Art

[0002] In construction projects, it is often necessary to dig foundation pits. During or after the excavation of the foundation pit, the surrounding soil will exert pressure on the foundation pit, which can easily cause the foundation pit to deform. The engineering staff have to repair or re-dig the foundation pit, which increases the amount of work, prolongs the construction period, and may even cause accidents. Therefore, during the construction process, it is often necessary to monitor whether the foundation pit is deformed, so as to take timely measures to reduce the loss caused by the deformation of the foundation pit.

[0003] A Chinese utility model patent with publication number CN212200516U discloses a deformation monitoring device for a construction pit, including a positioning mechanism and a monitoring mechanism, wherein the monitoring mechanism includes a monitoring shell, a fixed arm, a sliding arm, a pressure plate, a displacement sensor and an alarm; the monitoring shell is fixedly connected to the positioning mechanism; the fixed arm is sleeved with the sliding arm, the sliding arm can slide relative to the fixed arm along the axial direction of the sliding arm, the end of the fixed arm not connected to the sliding arm is fixed to the side of the monitoring shell, and the end of the sliding arm not connected to the fixed arm is fixedly connected to the pressure plate; one side of the pressure plate is fixedly connected to the sliding arm; the displacement sensor is fixed to the fixed arm, and its pull rod is fixedly connected to the pressure plate; the alarm is fixed to the monitoring shell and electrically connected to the displacement sensor.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the following defects exist: when the staff install the monitoring device, the staff needs to make the pressure plate close to the inner wall of the foundation pit, and the above-mentioned device drives the positioning pile to connect with the ground by connecting the rotating handle and the connecting baffle. In actual operation, the staff may easily cause the distance between the connecting baffle and the inner wall of the foundation pit to change during the rotation of the positioning pile, which may easily lead to a certain gap between the pressure plate and the inner wall of the foundation pit after the connecting baffle and the connecting plate are connected to each other. The staff needs to repeatedly adjust the position of the positioning pile, which results in a poor user experience. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a turnover foundation pit monitoring point installation structure.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a rotatable foundation pit monitoring point installation structure, including a connecting baffle, a positioning pile interconnected with the connecting baffle, a rotating handle threadedly connected to the upper surface of the connecting baffle, a connecting plate arranged on the upper surface of the connecting baffle, and a monitoring device arranged on the upper surface of the connecting plate, a sliding groove is provided on the upper surface of the connecting plate, a sliding block is slidably arranged in the sliding groove, the upper surface of the sliding block is fixed to the monitoring device, and a driving component for driving the sliding block is provided on the connecting plate.

[0007] By adopting the above technical solution, when using the monitoring device of this embodiment, first select a monitoring point near the inner wall of the building foundation pit, and the distance between the monitoring point and the inner wall of the foundation pit satisfies that the pressure plate on the monitoring device is tightly fitted to the inner wall of the foundation pit when the monitoring device is placed at this position. When the staff needs to install the monitoring device, the staff needs to make the rotating handle and the connecting baffle threadedly connected, so that the rotating handle and the connecting baffle remain stable. Subsequently, the staff only needs to make the bottom surface of the positioning pile close to the ground, and turn the rotating handle to make the positioning pile and the ground connected to each other, so that the connecting baffle remains stable. Further, the staff needs to connect the connecting plate and the connecting baffle to each other through bolts, so that the monitoring device can be initially kept stable. At this time, the staff needs to push the monitoring device, so that the pressure plate on the monitoring device can be flush with the inner wall of the foundation pit. Subsequently, the staff only needs to start the driving assembly, so that the monitoring device can continue to move toward the inner wall of the foundation pit, and then the pressure plate is pressed against the inner wall of the foundation pit, thereby reducing the probability of leaving a gap between the inner wall of the foundation pit and the pressure plate, thereby improving the user experience of the staff.

[0008] Furthermore, the connecting baffle and the upper surface of the connecting plate are both penetrated with connecting through holes, the upper surface of the connecting baffle is provided with a plurality of annular grooves corresponding to the connecting through holes one by one, and the bottom surface of the connecting plate is fixed with an annular sheet matching the annular grooves.

[0009] By adopting the above technical solution, when the staff needs to connect the connecting plate and the connecting baffle to each other, the staff only needs to place the connecting plate on the connecting baffle and slide the connecting plate left and right to connect the annular plate and the annular groove to each other, thereby reducing the difficulty for the staff to align the connecting through holes, thereby reducing the difficulty of the staff's operation.

[0010] Furthermore, a threaded hole is formed through the inner wall of the slide groove, and the driving assembly includes a telescopic rod arranged on the side wall of the slider near the threaded hole, a threaded rod rotatably connected to the telescopic rod, and a stabilizing device arranged on the telescopic rod for maintaining a stable length of the telescopic rod, and the threaded rod is threadedly connected to the threaded hole.

[0011] Furthermore, the telescopic rod includes a sleeve rod fixed to the side wall of the sliding block close to the threaded hole and a sleeve slidably connected to the sleeve rod.

[0012] By adopting the above technical solution, when the staff pushes the monitoring device, the slider and the sleeve rod move with the monitoring device. Furthermore, when the pressure plate is pressed against the inner wall of the foundation pit, the staff needs to turn on the stabilizing device to keep the sleeve rod stable. At this time, the staff only needs to turn the threaded rod to move the telescopic rod as a whole toward the inner wall of the foundation pit. Compared with directly twisting the threaded rod, this setting speeds up the difficulty for the staff to adjust the position of the monitoring device, thereby reducing the difficulty of the staff's operation.

[0013] Furthermore, a placement groove is provided on the inner wall of the slide groove, a placement block is slidably arranged in the placement groove, and the placement block and the sleeve are fixed to each other.

[0014] By adopting the above technical solution, the stability of the sleeve is improved, thereby reducing the probability of the sleeve following the rotation of the threaded rod, thereby improving the user experience of the staff.

[0015] Furthermore, the stabilizing device includes an annular block rotatably arranged on the side wall of the sleeve away from the threaded hole, a fixing block fixed to the annular block, and a fixing bolt threadedly connected to the upper surface of the fixing block.

[0016] Furthermore, a limiting groove is provided on the inner wall of the slide groove, a limiting block is slidably arranged in the limiting groove, and the limiting block and the fixing block are fixed to each other.

[0017] By adopting the above technical solution, when the pressure plate is pressed against the inner wall of the foundation pit, the staff only needs to turn the fixing bolts to make the fixing bolts press against the upper surface of the sleeve rod, thereby keeping the sleeve rod stable.

[0018] Furthermore, a magnet block is embedded on the side wall of the rotating handle, and the positioning pile is a positioning pile made of iron alloy.

[0019] By adopting the above technical solution, when the staff does not need to use the monitoring device, the staff only needs to remove the rotating handle and move the rotating handle close to the positioning pile, so that the rotating handle and the positioning pile can be adsorbed to each other, thereby reducing the probability of losing the rotating handle.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the present application, when using the monitoring device of the present embodiment, first select a monitoring point near the inner wall of the building foundation pit. The distance between the monitoring point and the inner wall of the foundation pit is sufficient to ensure that the pressure plate on the monitoring device is tightly fitted to the inner wall of the foundation pit when the monitoring device is placed at this position. When the staff needs to install the monitoring device, the staff needs to thread the rotating handle and the connecting baffle so that the rotating handle and the connecting baffle remain stable. Subsequently, the staff only needs to press the bottom surface of the positioning pile against the ground and turn the rotating handle to connect the positioning pile and the ground to keep the connecting baffle stable. Further, the staff needs to connect the connecting plate and the connecting baffle with bolts to initially keep the monitoring device stable. At this point, the staff needs to push the monitoring device so that the pressure plate on the monitoring device is flush with the inner wall of the foundation pit. Subsequently, the staff only needs to start the driving assembly to allow the monitoring device to continue to move toward the inner wall of the foundation pit, thereby pressing the pressure plate against the inner wall of the foundation pit, thereby reducing the probability of leaving a gap between the inner wall of the foundation pit and the pressure plate, thereby improving the staff's user experience;

[0022] 2. In the present application, when the staff needs to connect the connecting plate and the connecting baffle plate to each other, the staff only needs to place the connecting plate on the connecting baffle plate and slide the connecting plate left and right to connect the annular sheet and the annular groove to each other, thereby reducing the difficulty for the staff to make the connecting through holes face each other, thereby reducing the difficulty of the staff's operation;

[0023] 3. In this application, when the staff pushes the monitoring device, the slider and the sleeve rod move with the monitoring device. Furthermore, when the pressure plate is pressed against the inner wall of the foundation pit, the staff needs to turn on the stabilizing device to keep the sleeve rod stable. At this time, the staff only needs to turn the threaded rod to move the telescopic rod as a whole toward the inner wall of the foundation pit. Compared with directly twisting the threaded rod, this setting speeds up the difficulty for the staff to adjust the position of the monitoring device, thereby reducing the difficulty of the staff's operation.

[0036] The threaded rod 52 is rotatably connected to the side wall of the sleeve 512 away from the sleeve rod 511 , and the threaded rod 52 is threadedly connected to the threaded hole 41 .

[0037] When the staff pushes the monitoring device 3, the slider 4 and the sleeve rod 511 move with the monitoring device 3. Furthermore, when the pressure plate is pressed against the inner wall of the foundation pit, the staff needs to turn on the stabilizing device 6 to keep the sleeve rod 511 stable. At this time, the staff only needs to turn the threaded rod 52 to move the telescopic rod 51 as a whole toward the inner wall of the foundation pit. Compared with directly twisting the threaded rod 52, this setting speeds up the difficulty of the staff to adjust the position of the monitoring device 3, thereby reducing the difficulty of the staff's operation.

The limiting block 84 is a block-shaped structure, and the limiting block 84 is slidably arranged in the limiting groove 83, and the limiting block 84 and the fixing block 62 are fixed to each other.

[0040] When the pressure plate is pressed against the inner wall of the foundation pit, the staff only needs to rotate the fixing bolts 63 to make the fixing bolts 63 press against the upper surface of the sleeve rod 511, thereby keeping the sleeve rod 511 stable.

[0041] The upper surfaces of the connecting baffle 1 and the connecting plate 21 are both penetrated with connecting through holes 7, and the upper surface of the connecting baffle 1 is provided with a plurality of annular grooves 71 corresponding one to one with the connecting through holes 7.

A plurality of annular sheets 8 are provided and fixed on the bottom surface of the connecting plate 21, and the annular sheets 8 correspond one to one with the annular grooves 71 and match each other.

[0042] When the staff needs to connect the connecting plate 21 and the connecting baffle 1 to each other, the staff only needs to place the connecting plate 21 on the connecting baffle 1 and slide the connecting plate 21 left and right to connect the annular sheet 8 and the annular groove 71 to each other, thereby reducing the difficulty for the staff to align the connecting through hole 7, thereby reducing the difficulty of the staff's operation.

[0043] The magnet block 9 is a block structure, and the magnet block 9 is embedded in the side wall of the rotating handle 2, and the positioning pile 11 is made of iron alloy. When the staff does not need to use the monitoring device 3, the staff only needs to remove the rotating handle 2 and bring the rotating handle 2 close to the positioning pile 11, so that the rotating handle 2 and the positioning pile 11 can be adsorbed to each other, thereby reducing the probability of the rotating handle 2 being lost.

[0044] The use principle of a revolvable foundation pit monitoring point installation structure in this embodiment is as follows: when using the monitoring device 3 of this embodiment, first select a monitoring point near the inner wall of the building foundation pit, and the distance between the monitoring point and the inner wall of the foundation pit is sufficient to ensure that the pressure plate on the monitoring device 3 is tightly fitted to the inner wall of the foundation pit when the monitoring device 3 is placed at this position. When the staff needs to install the monitoring device 3, the staff needs to thread the rotating handle 2 and the connecting baffle 1 so that the rotating handle 2 and the connecting baffle 1 can remain stable. Subsequently, the staff only needs to make the bottom surface of the positioning pile 11 close to the ground and rotate the rotating handle 2 so that the positioning pile 11 can be connected to the ground, thereby keeping the connecting baffle 1 stable.
