[0002] In mining engineering, the slope measurement of roadway and working face is the key link to ensure construction safety and accuracy. As a mechanical measuring tool, the traditional slope gauge relies on gravity to indicate the inclination, has the advantages of simple structure, no external energy, strong anti-interference and calibration-free, and is especially suitable for blind well or deep mine measurement in satellite signal-free and harsh environment. It is usually used with traditional instruments such as theodolite, and the three-dimensional reconstruction of underground space is realized through trigonometric functions and geometric deduction, which is widely used in tunneling slope control, rock occurrence determination, equipment inclination correction and surrounding rock deformation monitoring.

[0003] However, the traditional slope gauge has obvious limitations in practical application: its measurement accuracy depends on the close contact between the bottom surface of the gauge and the measured surface, and the rock wall, top surface or ground in the mine is often uneven, especially on the protruding or irregular working face, it is difficult to ensure stable contact between the gauge and the measured surface, which leads to increased pointer indication error and cannot meet the demand of high-precision measurement. Therefore, a mining engineering surveying equipment that can adapt to complex mine environment and overcome the influence of uneven contact surface is needed to improve the reliability and efficiency of underground measurement.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Example 1: Please refer to Figures 1-7 This utility model provides a technical solution: a mining engineering measuring device, including a scale plate 1; the scale plate 1 has scales 101 evenly distributed on its front side, a top finding plate 2 is fixedly installed on the top of the scale plate 1, a plumb line shaft 201 is rotatably installed on the top finding plate 2, a plumb line 202 is fixedly connected to the plumb line shaft 201, and a weight 203 is fixedly installed at the end of the plumb line 202. When the surface of the target object is flat, the top finding plate 2 is pressed against the surface of the object to be measured. At this time, the plumb line 202 and the weight 203 on the top finding plate 2 hang down naturally under gravity, and the scale 101 pointed to by the end of the weight 203 is the slope of the surface of the object to be measured.

[0025] When the object being measured is uneven and cannot be directly measured using the top leveling plate 2, a slide rail 3 is fixedly installed on the rear side of the scale plate 1. A sliding groove 301 is provided on the slide rail 3, and a connector 4 is slidably installed within the sliding groove 301. A sleeve rod 5 is rotatably installed on the connector 4, and a rotating shaft 606 is fixedly installed on the connector 4. One end of the sleeve rod 5 has a rotating shaft groove, and the rotating shaft 606 is rotatably installed within the rotating shaft groove. A limiting slot 204 is fixedly installed on the top leveling plate 2. The limiting slot 204 is adapted to the sleeve rod 5. When the connector 4 slides along the sliding groove 301, it can drive the sleeve rod 5 to move towards the limiting slot 204 until the end of the sleeve rod 5 is engaged in the limiting slot 204 and locked. Figure 2 With the middle sleeve 5 locked in the limiting slot 204 at its end, pulling the sleeve 5 on the back of the scale plate 1 to both sides allows the end of the sleeve 5 to disengage from the limiting slot 204, and the unlocked sleeve 5 can then unfold to both sides. Figure 1 (The middle sleeve 5 is in a state of being extended to both sides).

[0026] The slide rail 3 and the connecting member 4 are provided with a rotating mechanism 6. The rotating mechanism 6 includes a slider 601 for changing the position and direction of the sleeve rod 5. The slider 601 is slidably installed in the sliding groove 301. The connecting member 4 is rotatably installed on the slider 601. A spring-loaded reset plate 602 is slidably installed on the side of the slide rail 3 away from the top seeking plate 2. When the connecting member 4 is located at the end of the sliding groove 301 away from the top seeking plate 2, the connecting member 4 is in contact with the spring-loaded reset plate 602. A tension groove 603 is provided at the bottom of the slide rail 3. A slide rod 604 is fixedly installed at the bottom of the spring-loaded reset plate 602. The slide rod 604 is slidably installed in the tension groove 603. A reset spring 605 is sleeved on the slide rod 604 for resetting. One end of the spring 605 is installed on the inner wall of the tension groove 603, and the other end of the return spring 605 is installed on the slide rod 604. When the connecting piece 4 slides to the end of the sliding groove 301 away from the top plate 2, after the connecting piece 4 contacts the elastic return plate 602, the connecting piece 4 continues to move, causing the elastic return plate 602 to stretch outward a certain distance. At this time, the slide rod 604 at the bottom of the elastic return plate 602 slides in the tension groove 603 and compresses the return spring 605. At this time, the elastic return plate 602 separates from the slide rail 3, and the space between the elastic return plate 602 and the slide rail 3 allows the connecting piece 4 to rotate. After rotating the connecting piece 4 ninety degrees, the sleeve rod 5 rotates upward or downward. Figure 3 (When the middle sleeve rod 5 is in an upward rotating state), the elastic reset plate 602 is released, and under the action of the reset spring 605 in the tension groove 603, it returns to its initial position. At this time, the sleeve rod 5 can maintain an upward or downward state and move left and right on the slide rail 3. The elastic reset plate 602 is provided to prevent the connecting member 4 from dislodging from the sliding groove 301 of the slide rail 3 when sliding along the slide rail 3 without restricting the rotation of the connecting member 4.

[0027] Example 2: AsFigure 1 , 3 In order to enable the end of the extension rod 701 to contact the measuring point, the sleeve rod 5 is provided with an extension mechanism 7. The extension mechanism 7 includes the extension rod 701. The sleeve rod 5 is hollow inside, and the extension rod 701 is slidably installed inside the sleeve rod 5. The extension rod 701 and the sleeve rod 5 are in telescopic cooperation. The outer wall of the sleeve rod 5 is provided with a toothed groove 702. An elastic clip 703 is fixedly installed on the extension rod 701. The elastic clip 703 is located in the toothed groove 702. Two elastic rods 704 are fixedly connected to the elastic clip 703. The elastic rods 704 are provided with... Equipped with locking teeth, two elastic rods 704 engage with toothed grooves 702 via the locking teeth. When the measurement length needs to be extended, the extension rod 701 can be stretched outwards, causing it to elongate relative to the sleeve rod 5. At this time, the elastic rods 704 of the elastic locking member 703 undergo elastic deformation under the limiting effect of the toothed grooves 702, and after being stretched to the target position, they achieve self-locking fixation through the engagement of the locking teeth and toothed grooves 702. This ensures that the end of the extension rod 701 stably contacts the measurement point, thereby improving measurement accuracy and preventing accidental retraction during the measurement process. Figure 1 , Figure 3 (The extension rod 701 is in the extended state). The remaining features are the same as in Example 1.

[0028] The working principle is as follows: When measuring the slope of the uneven rock wall inside the mine, the sleeve 5 on the back of the scale plate 1 is pulled out to both sides, so that the end of the sleeve 5 is disengaged from the limiting slot 204. After the sleeve 5 is unlocked, it can be unfolded to both sides. At this time, the sleeve 5 is perpendicular to the scale plate 1 and slides in the sliding groove 301 through the connecting piece 4. The position of the two sleeves 5 is adjusted. Through the locking structure of the tooth groove 702 on the sleeve 5 and the elastic locking piece 703 on the extension rod 701, the extension rod 701 is stretched step by step. The extension length of the two extension rods 701 is adjusted, and the ends of the two extension rods 701 are respectively placed against the measurement points. At this time, the plumb line 202 and the weight 203 on the top plate 2 hang down naturally under gravity. The scale 101 pointed to by the end of the weight 203 is the slope between the two measurement points.

[0029] When it is necessary to measure the slope of the uneven rock top surface or ground surface inside the mine, slide the connector 4 to the end of the sliding groove 301 away from the top leveling plate 2. After the connector 4 contacts the elastic reset plate 602, continue to move the connector 4, causing the elastic reset plate 602 to stretch outward a certain distance. At this time, the slide rod 604 at the bottom of the elastic reset plate 602 slides in the stretching groove 603 and compresses the reset spring 605. At this time, the elastic reset plate 602 separates from the slide rail 3, and the space between the elastic reset plate 602 and the slide rail 3 allows the connector 4 to rotate. After rotating the connector 4 ninety degrees, the sleeve rod 5 rotates upward or downward. Then, the ends of the two extension rods 701 on both sides are placed against the measuring points to take the reading. When the sleeve rod 5 rotates upward, the mining engineering measuring device can be used to measure the slope of the rock top surface inside the mine. When the sleeve rod 5 rotates downward, the mining engineering measuring device can be used to measure the slope of the rock ground surface inside the mine.
