[0002] At present, in mine surveying, leveling based on tower rods is often used to determine the height difference of the ground or buildings, providing accurate elevation data for mine mining and planning. In addition to leveling, tower rods can also be used for mine fragment measurement. Fragment measurement is the measurement of detailed features such as mine terrain and landforms. Tower rods can easily measure the elevation of various terrain feature points and provide detailed terrain data for mine mining.

[0003] In the prior art, a Chinese patent with publication number CN217275860U discloses a convenient caliper, comprising a tapered ruler and a knob buckle; the tapered ruler can be extended and retracted along its length direction, thereby adjusting the length distance; the tapered ruler is made of aluminum alloy material, and the front and back sides of the tapered ruler are provided with consistent scales along its length direction; the knob buckle is provided on the tapered ruler and can be moved on the tapered ruler along the length direction of the tapered ruler, thereby adjusting the exposed length of the tapered ruler. When in use, the tapered ruler is extended along its length direction, then placed vertically at a detection point, and then detected with a level.

[0004] However, after the scale is used many times, the inner and outer scales are frequently plugged in and out, causing the scales on the scales to be worn and unclear. When reading, the scales cannot be seen clearly, affecting the test results. Utility Model Content

[0005] In order to reduce the impact on the detection results, the present application provides a tower scale structure for mine measurement.

[0006] This application provides a mine surveying tower structure, which adopts the following technical solutions:

[0008] A bottom ruler is provided with a first scale along its length direction, and one end of the bottom ruler is provided with a sliding hole along its length direction;

[0009] An abutment seat is detachably connected to an end of the base ruler away from the sliding hole, and a smooth placement surface is formed on a side away from the base ruler;

[0010] The first tower section slides in the sliding hole, with a gap between it and the side wall of the sliding hole, and a second scale is opened along the length direction of the first tower section, and the second scale is continuously arranged with the first scale;

[0011] Two groups of rolling elements are provided, and are respectively located on both sides of the first tower section, and are both provided on the inner wall of the sliding hole, and are rollingly connected to the first tower section, and are used to reduce the friction between the second scale and the bottom scale;

[0012] A locking assembly includes a first locking rod slidably disposed on the base rule, the first locking rod being close to the first tower section for limiting the sliding of the first tower section;

[0013] a brush, provided on the bottom ruler and located at the sliding hole, in flexible contact with the first tower section;

[0014] The bottom ruler is provided with an adjustment component, and the adjustment component includes:

[0015] An adjusting plate slides in the sliding hole, and the rolling element on one side is arranged on the adjusting plate;

[0016] An adjusting bolt is threadedly connected to the bottom ruler and is rotatably connected to the adjusting plate, so as to push the adjusting plate toward or away from the first tower section.

[0017] By adopting the above technical solution, when conducting mining engineering surveying and construction, the first tower section is first slid upward, and the first tower section slides through the rolling element. Then, the first locking rod is slid so that the first locking rod is pressed against the first tower section. Then, the abutment seat is abutted against the position to be detected. Then, the bottom ruler is straightened so that the bottom ruler remains vertical. Then, readings are taken using a level. The above tower ruler has a simple structure, and the provision of the rolling element converts the static friction between the first tower section and the bottom ruler into dynamic friction, reducing wear on the second scale. This allows for quick readings, reduces hesitation during readings, and reduces inaccurate readings, making the test results more accurate and extending the service life of the tower ruler.

[0018] When the rolling element becomes loose or stuck after long-term use, the adjusting bolt is rotated to drive the adjusting plate to squeeze or release the rolling element, so that the sliding of the first tower section becomes smoother. The setting of the rolling elements on both sides restricts the movement of the first tower section, making the movement more stable, reducing the tilt of the first tower section caused by the misalignment of the axes of the first tower section and the bottom scale, reducing reading errors, and the gap between the first tower section and the bottom scale reduces the overall wear of the outer surface of the first tower section, thereby enhancing the sliding stability between the first tower section and the bottom scale.

When the first tower section is contracted, the position of the force-applying part is adjusted, and the first elastic member drives the adjustment block away from the first tower section, and then slides the first tower section closer to the abutment seat by itself. The force-applying part and the first elastic member are set, which facilitates the rapid sliding of the first tower section, reduces the friction between the first locking rod and the first tower section, extends the service life of the first tower section, and can reduce the shaking of the first tower section caused by wear, maintain the stability of the tower ruler, and facilitate the accuracy of the detection results.

[0026] By adopting the above technical solution, when the position of the first tower section slides into place, the adjusting block is pressed down, and the adjusting block drives the first locking rod to approach the wedge block, and the wedge block drives the first locking rod to overcome the elastic force of the first elastic member, so that the first locking rod is pressed against the first tower section; after use, the adjusting block is slid upward, so that the first locking rod is separated from the first tower section under the elastic force of the first elastic member, achieving quick separation, facilitating quick sliding of the first tower section, making the disassembly and assembly of the tower ruler simple, and when in use, the first tower section presses the first locking rod under its own gravity to better press against the first tower section; the realization of quick separation facilitates movement in uneven areas of the mine, reduces collisions of the tower ruler, and can also reduce safety hazards caused by the excessive length of the tower ruler when people move.

[0027] Optionally, the force-applying portion is a bolt, the bolt is threadedly connected to the adjustment block, and the bolt abuts against the first locking rod and drives the first locking rod to approach the first tower section.

[0028] By adopting the above technical solution, when the position of the first tower section slides into place, the bolt is rotated, and the bolt drives the first locking rod to overcome the elastic force of the first elastic member and press against the first tower section. Through the setting of the bolt, the stability of the first tower section is made higher, which is convenient for multi-point measurement and the accuracy of the results can be maintained.
