[0037] Example:
[0038] like Figure 1 As shown, this embodiment provides a displacement observation pile for a turnout, including a container 2 and a hollow observation pile 3. The hollow observation pile 3 is installed on the container 2, and both the container 2 and the hollow observation pile 3 are installed inside the engineering well 1. The top of the engineering well 1 is provided with a well cover 101.
[0039] Specifically, such as Figure 3As shown, the container 2 comprises a box body 201, the box body 201 is a cuboid, the box body 201 is provided with a through hole and a mounting hole at the top, the transmission shaft 202 is penetrated through the through hole at the top of the box body 201, the bottom of the transmission shaft 202 is fixedly connected with the first bevel gear 203, the top of the transmission shaft 202 is fixedly connected with the rotary disc type handle 207, the first bevel gear 203 is meshingly arranged with the second bevel gear 204, the second bevel gear 204 is coaxially connected with the third bevel gear 206 through the connecting shaft 205, one end of the connecting shaft 205 is connected to the inner wall of the box body 201 through a bearing, which is convenient to reduce the friction when rotating, and the other end penetrates the second bevel gear 204 and the third bevel gear 206 in sequence, and the bottom surface of the second bevel gear 204 is oppositely arranged with the bottom surface of the third bevel gear 206.
[0040] Rotating the rotary disc type handle 207 drives the transmission shaft 202 to rotate, and then drives the first bevel gear 203 to rotate, the rotation of the first bevel gear 203 drives the second bevel gear 204 meshingly arranged therewith to rotate, and then drives the third bevel gear 206 coaxially arranged with the second bevel gear 204 to rotate.
[0041] In the embodiment, the hollow observation pile 3 is cylindrical, and a plug hole is formed at the bottom, the hollow observation pile 3 penetrates the mounting hole at the top of the box body 201 and is arranged in parallel with the transmission shaft 202.
[0042] The hollow observation pile 3 is provided with a rotating and lifting assembly 4 inside, the rotating and lifting assembly 4 is connected with the fourth bevel gear 5, and the fourth bevel gear 5 is meshingly arranged inside the container 2.
[0043] Specifically, as shown, Figure 2 The rotating and lifting assembly 4 comprises a threaded sleeve 403, a threaded column 401 and two fixed blocks 402, the threaded column 401 is arranged inside the hollow observation pile 3, the diameter of the threaded column 401 is smaller than the diameter of the plug hole, and the bottom of the threaded column 401 extends downward to the outside of the hollow observation pile 3 through the plug hole to connect the rotating base 6, the threaded sleeve 403 is threadedly sleeved on the outer periphery of the threaded column 401, the fixed blocks 402 are symmetrically fixed between the outer side wall of the threaded sleeve 403 and the inner side wall of the hollow observation pile 3, the threaded column 401 rotates to drive the threaded sleeve 403 to move up and down along the axis direction of the threaded column 401, so as to drive the hollow observation pile 3 to move up and down through the fixed blocks 402.
[0044] By using the threaded connection principle, the relative movement between the threaded sleeve 403 and the threaded column 401 has high stability and accuracy, which ensures the accuracy of displacement observation and makes the observation result more reliable, the fixed blocks 402 are arranged between the hollow observation pile 3 and the threaded sleeve 403, which further enhances the stability of the movement of the threaded sleeve 403 and reduces the observation error caused by shaking or deviation.

Through the rotation of the rotating disc 602, the threaded column 401 can be slightly angularly adjusted. Therefore, the hollow observation pile 3 can be angularly adjusted while being lifted, so as to adapt to different switches or engineering requirements.
[0047] In order to ensure the stability and accuracy of the hollow observation pile 3 during lifting, a guide assembly is arranged on the outer wall of the hollow observation pile 3.

One end of the sliding block 7 is slidingly arranged in the sliding rail 8, and the other end is fixed on the outer wall of the hollow observation pile 3. The hollow observation pile 3 moves up and down while the sliding block 7 moves up and down along the sliding rail 8. The sliding block 7 provides a stable guide for the lifting of the hollow observation pile 3. At the same time, the sliding block 7 also limits the lateral movement of the hollow observation pile 3, thereby enhancing the structural stability of the hollow observation pile 3.
[0048] A high-precision displacement sensor 301 is installed on the inner wall of the hollow observation pile 3. The high-precision displacement sensor 301 can monitor the lifting displacement of the hollow observation pile 3 in real time and accurately, and convert these data into electrical signals for output.

The data transmission module 208 adopts wireless communication technology, receives electrical signals from the high-precision displacement sensor 301, and converts them into a data format suitable for long-distance transmission, ensuring that the data can be accurately and quickly transmitted to the designated location. This facilitates the timely discovery of potential problems, so that the displacement of the hollow observation pile 3 can be monitored in real time while it is stably lifted, and the data can be transmitted to the relevant system for analysis and processing in a timely manner. This can timely discover abnormal displacement of the switch, take measures in advance, avoid safety accidents, improve railway operation safety, and greatly improve the accuracy and efficiency of engineering monitoring, thereby providing a strong guarantee for engineering safety and quality.
[0050] In the embodiment, the fixing method is to fix by expansion bolts or anchoring agent.
[0051] In this embodiment, the hollow observation pile 3 is made of high-strength composite material, is corrosion-resistant and impact-resistant, and is suitable for various complex terrains and environmental conditions.
[0052] The use process of this embodiment is as follows:
[0053] The operator opens the well lid 101, rotates the rotary disc handle 207, the transmission shaft 202 rotates synchronously, the first bevel gear 203 at the bottom of the transmission shaft 202 also rotates synchronously, thereby driving the second bevel gear 204 meshing with the first bevel gear 203 to rotate, the second bevel gear 204 drives the third bevel gear 206 to rotate through the connecting shaft 205, the third bevel gear 206 drives the fourth bevel gear 5 meshing therewith to rotate, the fourth bevel gear 5 drives the threaded column 401 fixedly connected thereto to rotate, thereby making the threaded sleeve 403 and the hollow observation pile 3 ascend along the axial direction of the threaded column 401, the sliding block 7 provides a stable guiding effect for the hollow observation pile 3, after use, the rotary disc handle 207 is rotated in the opposite direction, so that the threaded sleeve 403 and the hollow observation pile 3 descend along the axial direction of the threaded column 401, the principle is the same as that of the ascending principle, then the well lid 101 is covered, and the operation is completed.
[0054] The above describes the utility model by using specific examples, which is only used to help understand the utility model and does not limit the utility model.
