Description

Technical Field

[0001] This utility model relates to the field of foundation pit monitoring technology, and in particular to a foundation pit deformation detection device for foundation pit monitoring. Background Technology

[0002] Foundation pit monitoring is a crucial aspect of ensuring construction safety. Through systematic and continuous observation and analysis of the foundation pit and its surrounding environment, safety accidents can be prevented. Monitoring content includes displacement and settlement of the support structure, deformation of surrounding buildings and underground pipelines, and changes in groundwater levels. The total station, as a key measuring instrument, plays a vital role in foundation pit monitoring due to its high precision and multifunctionality. It can quickly and accurately measure the three-dimensional coordinates of various points within the foundation pit, acquire real-time data on horizontal displacement and vertical settlement of the support structure, and monitor the tilt and cracks of surrounding buildings. This provides reliable data support for the construction team to promptly grasp the dynamics of the foundation pit, adjust construction plans, and ensure the safety and stability of the foundation pit and its surrounding environment.

[0003] A search revealed that patent CN220058125U discloses "a foundation pit deformation detection device." Although the support rods under the sleeve are arranged in a triangular pattern, providing stability and allowing the total station to be stably placed on the edge of the foundation pit during use, it is not easily damaged by external impacts, thus enabling the foundation pit deformation detection device to be used continuously. However, this device only achieves its support function through the support rods and lacks a mechanism to establish an effective connection with the ground. This leads to the device being prone to overall displacement when encountering strong external interference, which greatly affects the accuracy of the detection data.

[0004] To address the aforementioned technical shortcomings, a solution is proposed that connects the device to the ground, thereby preventing slippage caused by external forces and improving the accuracy of the detection data. Utility Model Content

[0005] The purpose of this invention is to provide a foundation pit deformation detection device for foundation pit monitoring, in order to solve the problems mentioned above.

[0006] The purpose of this utility model can be achieved through the following technical solution: a foundation pit deformation detection device for foundation pit monitoring, including a connecting seat, support rods hinged to both sides of the connecting seat, a hinge seat fixedly connected to the lower end of the connecting seat, a rotating rod provided on the inner wall of the hinge seat, a support block fixedly connected to one end of the rotating rod, an anchor hole through the inside of the support block, a locking hole on one side of the support block, and a support column fixedly connected to the lower end of the connecting seat; A fixing block is fixedly connected to the outer side of the support near the hinge seat. A sliding rod is provided inside the fixing block. A limit ring is fixedly connected to one end of the sliding rod. A spring is provided on one side of the limit ring, and a locking rod is fixedly connected to the other side of the limit ring.

[0007] Preferably, the upper end of the connecting seat is provided with a hydraulic rod, the upper end of the hydraulic rod is fixedly connected to a fixed seat, the upper end of the fixed seat is provided with a positioning hole, the upper edge of the fixed seat is provided with a threaded hole, and a positioning rod is provided inside the positioning hole.

[0008] Preferably, an assembly plate is fixedly connected to the upper end of the positioning rod, the total station body is provided on the upper end of the assembly plate, short blocks are fixedly connected to both sides of the assembly plate, a rotating hole is opened inside the short block, a connecting rod is provided inside the rotating hole, a connecting ring is fixedly connected to one end of the connecting rod, and a screw is fixedly connected to the other side of the connecting ring.

[0009] Preferably, the number of support blocks is multiple sets, and they are arranged at equal angles on the outside of the support rod. The support blocks are rotatably connected to the hinge seat through rotating rods on both sides.

[0010] Preferably, the slide bar slides inside the fixed block via a limiting ring and a spring.

[0011] Preferably, the screw has external threads evenly distributed on its surface, and these threads are adapted to the threaded holes inside the fixed seat. The screw is movably connected to the short block via a connecting rod.

[0012] The beneficial effects of this utility model are: (1) By pulling the slide bar, the slide bar drives the limiting ring to move and compresses the spring. During this process, the locking rod comes out from the inside of the locking hole, releasing the limiting of the rotating block. Then, the rotating block is rotated to an angle perpendicular to the support. The staff can pass the external anchor rod through the anchor hole to fix the rotating block, thus completing the auxiliary fixation of the device. Similarly, the rotating block can be stored by reversing the above steps. The device can be connected to the ground through the rotating rod, rotating block, fixing block, slide bar, spring, locking rod and other components, which can avoid slippage caused by external force and improve the accuracy of the detection data. (2) By rotating the connecting rod, the connecting rod drives the screw to rotate. Under the action of the threaded hole inside the assembly plate, the connecting rod and the screw move upward. At this time, pull the assembly plate, and the assembly plate drives the positioning rod to slide out from the inside of the positioning hole, so as to disassemble the main body of the total station and facilitate the maintenance of the staff. Similarly, during installation, slide the positioning rod into the inside of the positioning hole. After it reaches the preset position, rotate the connecting rod in the opposite direction, and the stud will enter the threaded hole again to realize the installation and fixation of the main body of the total station. The main body of the total station can be quickly assembled and disassembled through the connecting rod, screw, short block and other components, so that it can be maintained during long-term use and the difficulty of maintenance can be reduced.

[0015] 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.

[0016] Example 1: The application background of this utility model is based on the fact that the device only achieves the support function through the support rod and lacks a mechanism to establish an effective connection with the ground. This leads to the device being prone to overall displacement when encountering strong external interference, which greatly affects the accuracy of the detection data. The technical solution of this utility model is to solve the problem of how to establish a connection between the device and the ground, thereby avoiding slippage caused by external forces and improving the accuracy of the detection data. Please see Figure 1 - Figure 6As shown, this embodiment is a foundation pit deformation detection device for foundation pit monitoring, including a connecting seat 1, with support rods 2 hinged to both sides of the connecting seat 1, and a hinge seat 4 fixedly connected to the lower end of the connecting seat 1. A rotating rod 5 is provided on the inner wall of the hinge seat 4, and a support block 6 is fixedly connected to one end of the rotating rod 5. An anchor hole 7 is provided through the inside of the support block 6, and a locking hole 8 is provided on one side of the support block 6. A support column 3 is fixedly connected to the lower end of the connecting seat 1, and a fixing block 9 is fixedly connected to the outer side of the support column 3 near the hinge seat 4. A sliding rod 10 is provided inside the fixing block 9, and a limiting ring 11 is fixedly connected to one end of the sliding rod 10. A spring 12 is provided on one side of the limiting ring 11, and a locking rod 13 is fixedly connected to the other side of the limiting ring 11. There are multiple sets of support blocks 6, and they are arranged at equal angles on the outer side of the support rods 2. The support blocks 6 are rotatably connected to the hinge seat 4 through the rotating rods 5 on both sides, and the sliding rod 10 slides inside the fixing block 9 through the limiting ring 11 and the spring 12. When using this device, firstly, with the help of support rod 2, support column 3, etc., it is erected in a pre-set position outside the foundation pit. Then, pull the sliding rod 10, which drives the limiting ring 11 to move and compress the spring 12. During this process, the locking rod 13 disengages from the inside of the locking hole 8, releasing the limiting of the rotating block. Then, rotate the rotating block to an angle perpendicular to the support column 3. The worker can then pass the external anchor rod through the anchor hole 7 to fix the rotating block, thus completing the auxiliary fixation of the device. Similarly, by reversing the above steps, the rotating block can also be stored. The rotating rod 5, rotating block, fixing block 9, sliding rod 10, spring 12, locking rod 13 and other components can establish a connection between the device and the ground, thereby avoiding slippage caused by external forces and improving the accuracy of the detection data.

[0017] Example 2: Please refer to Figure 1 - Figure 6 As shown, this embodiment is a foundation pit deformation detection device for foundation pit monitoring. A hydraulic rod 14 is provided at the upper end of the connecting seat 1. A fixed seat 15 is fixedly connected to the upper end of the hydraulic rod 14. A positioning hole 16 is opened at the upper end of the fixed seat 15. A threaded hole 17 is opened at the upper edge of the fixed seat 15. A positioning rod 18 is provided inside the positioning hole 16. An assembly plate 19 is fixedly connected to the upper end of the positioning rod 18.

A screw 25 is fixedly connected to the other side of the connecting ring 24. The surface of the screw 25 is evenly distributed with external threads, and it is adapted to the threaded hole 17 inside the fixed seat 15. The screw 25 is movably connected to the short block 21 through the connecting rod 23. When the total station body 20 needs maintenance, the connecting rod 23 is rotated, which drives the screw 25 to rotate. Under the action of the threaded hole 17 inside the assembly plate 19, the connecting rod 23 and the screw 25 move upward. At this time, the assembly plate 19 is pulled, and the assembly plate 19 drives the positioning rod 18 to slide out from the inside of the positioning hole 16, realizing the disassembly of the total station body 20, which is convenient for maintenance personnel. Similarly, during installation, the positioning rod 18 is slid into the inside of the positioning hole 16. After it reaches the preset position, the connecting rod 23 is rotated in the opposite direction, and the stud will re-enter the threaded hole 17, realizing the installation and fixation of the total station body 20. The components such as the connecting rod 23, screw 25, and short block 21 can quickly assemble and disassemble the total station body 20, which can be maintained during long-term use and at the same time reduce the difficulty of maintenance.

[0018] Combining Embodiment 1 and Embodiment 2, it can be seen that: on the one hand, the device can be connected to the ground by components such as rotating rod 5, rotating block, fixing block 9, sliding rod 10, spring 12, and locking rod 13, thereby avoiding slippage caused by external forces and improving the accuracy of detection data; on the other hand, the total station body 20 can be quickly assembled and disassembled by components such as connecting rod 23, screw 25, and short block 21, thereby enabling maintenance during long-term use and reducing the difficulty of maintenance.

[0019] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
