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 scope of protection of the present utility model.

[0025] The core of this utility model is to provide a top and bottom plate observation signal column, which will be described below in conjunction with... Figures 1-4 A detailed description of each component that makes up this signal column is provided below:

[0026] The top and bottom plate observation signal column includes a support base 1. A first main pipe 2 is fixedly connected to the upper surface of the support base 1. A scale 3 is provided on the outer surface of the first main pipe 2. A second main pipe 5 is provided at one end of the first main pipe 2 relative to the support base 1. Multiple nuts 6 are fixedly connected to both sides of the second main pipe 5, and a bolt 7 is provided on one side of the nuts 6. Specifically, in use, the support base 1 provides stable support for the first main pipe 2. It is fixed to its bottom end by welding and embedded in the hard part of the bottom plate to increase the contact area between the device and the bottom plate, ensuring that the whole is stable on the roadway floor and avoiding tilting or displacement of the device due to uneven stress on the bottom plate. The first main pipe 2 serves as the basic support structure of the device. The support base is fixed at the bottom end, and the scale 3 is attached to the outer side of the column body to support the sliding connection of the second main pipe 5. The scale 3 visually displays the displacement changes of the top and bottom plates. The graduated scale 3 is affixed to the surface of the first main pipe 2, serving as the core measuring component for observing changes in the top and bottom plates. Construction personnel can quickly obtain settlement or uplift data of the top and bottom plates by reading the scale value, achieving intuitive and accurate displacement observation. The second main pipe 5 is fitted onto the outside of the first main pipe 2 to form a sliding connection. A load-bearing plate 8 is welded to its top and fixed to the top plate. It expands and contracts with the displacement of the top plate, and its own up-and-down sliding causes changes in the reading of the graduated scale 3, reflecting the relative displacement between the top and bottom plates. The bolt 7, in conjunction with the nut 6, can be used to fix the expanding and contracting parts of the first main pipe 2 and the second main pipe 5, locking their relative positions when not under observation, preventing scale deviation due to accidental touch or vibration, and ensuring the accuracy of the observation data.

[0027] The second main pipe 5 is fixedly connected to a force-bearing plate 8 at one end relative to the first main pipe 2. Specifically, the force-bearing plate 8 is welded to the top of the second main pipe 5 and has a size of 100mm×100mm. By fixing it to the top plate, the displacement change of the top plate is transmitted to the second main pipe 5, so that the telescopic column can respond to the settlement or heave of the top plate in real time and ensure the timeliness of observation.

[0028] The outer surface of the first main pipe 2 is provided with a long arc plate 9; specifically, the long arc plate 9 can be combined with the short arc plate 11 to form a circular plate, which is then fixed on the first main pipe 2.

[0029] A hinge 10 is provided on one side of the long arc plate 9; specifically, the hinge 10 can provide rotation for the connection between the short arc plate 11 and the long arc plate 9.

[0030] A short arc plate 11 is provided at one end of the hinge 10 relative to the long arc plate 9; specifically, the short arc plate 11 can be connected to the long arc plate 9 to form a circular plate, making the overall structure more stable.

[0031] A main fixing plate 12 is provided at one end of the long arc-shaped plate 9 relative to the hinge 10; specifically, the main fixing plate 12 connects the long arc-shaped plate 9 and the fixing screw 14, making the overall structure more stable.

[0032] A secondary fixing plate 13 is provided at one end of the short arc plate 11 relative to the hinge 10. A through hole is provided on one side of the main fixing plate 12, and multiple fixing screws 14 are provided. Specifically, the fixing screws 14 can penetrate the main fixing plate 12 and the secondary fixing plate 13 and are connected and fixed on one side of the secondary fixing plate 13 by nuts, thereby making the circular plate structure more stable.

[0033] Multiple connecting rods 15 are provided on one side of the short arc plate 11; specifically, the connecting rods 15 connect the short arc plate 11 and the support plate 16, which ensures the stability and integrity of the overall structure and is one of the important components of the overall structure.

[0034] A support plate 16 is fixedly connected to one end of the connecting rod 15 relative to the short arc plate 11; specifically, the support plate 16 supports the bottom of the mine shaft, ensuring the stability of the overall structure during use.

[0035] In summary:

[0036] In use, the support base 1 provides stable support for the first main pipe 2. It is welded to its bottom and embedded in the hardened part of the base plate to increase the contact area between the device and the base plate, ensuring the device stands stably on the tunnel floor and preventing tilting or displacement due to uneven stress on the base plate. The first main pipe 2 serves as the basic support structure of the device, with the support base 1 fixed at its bottom. A scale 3 is attached to the outside of the column to support the sliding connection of the second main pipe 5. The scale 3 visually displays the displacement changes of the top and bottom plates. The scale 3, attached to the surface of the first main pipe 2, serves as the core measuring component for observing changes in the top and bottom plates. Construction personnel can quickly obtain settlement or uplift data of the top and bottom plates by reading the scale value, achieving intuitive and accurate displacement observation. The second main pipe is fitted onto the outside of the first main pipe 2 to form a sliding connection. A load-bearing plate is welded to its top and fixed to the top plate. It expands and contracts with the displacement of the top plate, and its own up-and-down sliding causes changes in the scale 3 reading, reflecting the relative displacement between the top and bottom plates. The bolt, in conjunction with the nut, can be used to fix the telescopic movable parts of the first main pipe 2 and the second main pipe 5, locking their relative positions when not under observation, preventing scale deviation due to accidental touch or vibration, and ensuring the accuracy of the observation data.
