Description

Technical Field

[0001] This utility model relates to the field of underground coal mine detection, and more specifically, to a mine tilt measuring instrument. Background Technology

[0002] Transient electromagnetic methods are a mature geophysical exploration technique, but when conducting geological surveys in magnetite mines, the geological compass is inaccurate due to the influence of magnetic force. Moreover, multiple angles need to be measured during the exploration. In actual measurement, the distance between each measuring line (angle) and the horizontal distance can be directly measured with a tape measure, so the inclination angle of the measuring point is difficult to grasp. When the slope of the tunnel changes and the direction of the exploration changes, the angle is not only difficult to measure, but also has a large error. In addition, it is difficult to make the bottom of the underground tunnel completely horizontal. Setting the level instrument horizontally is time-consuming and has poor accuracy.

[0003] In the prior art, Chinese utility model patent with publication number CN219038001U discloses a mine inclination measuring instrument. This prior art avoids the tedious operation of repeatedly installing the plumb line by fixing the slope gauge to the measuring bracket and using the natural descent of the plumb bob to indicate the inclination angle. However, in actual use, due to the disturbance of underground ventilation airflow and the vibration of the bracket caused by personnel operation, the plumb bob, as a freely suspended pendulum, is prone to continuous swinging. This causes the operator to have to wait for a long time for the plumb bob to come to rest in order to read the value accurately, which seriously reduces the efficiency of measurement. At the same time, if the reading is estimated when the plumb bob is not completely still, the swing of the plumb line will cause reading errors. In view of this, we propose a mine inclination measuring instrument to solve the above problems. Utility Model Content

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A mining tilt measuring instrument includes a support frame 1 for support, a mounting frame 2 externally mounted on the support frame 1, a scale 3 for viewing the tilt angle externally mounted on the mounting frame 2, a semi-ring 19 fixedly connected to the side surface of the mounting frame 2 near the support frame 1, and the mounting frame 2 being detachably and movably fitted onto the outside of the support frame 1 via the semi-ring 19, a damping box 4 fixedly connected to the surface of the mounting frame 2, a connecting rod 5 externally mounted on the damping box 4, and a mechanism for driving the connecting rod 5 to swing at its lower end. The damping box 4 has a first cavity 6 inside, and a rotating shaft 7 is rotatably connected inside the first cavity 6. The front end of the rotating shaft 7 rotatably extends out of the damping box 4, and the connecting rod 5 is fixedly sleeved on the outside of the rotating shaft 7. A connecting mechanism is provided on the outside of the rotating shaft 7. A push plate 10 is provided inside the first cavity 6, and a gap is left between the edge of the push plate 10 and the inner wall of the first cavity 6. Both sides of the damping box 4 have through holes 11 that communicate with the first cavity 6.

[0030] Example 2

[0031] The mine inclination measuring instrument provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, two partition plates 8 are fixedly connected inside the first cavity 6. Sliding rods 9 are slidably sleeved inside the two partition plates 8. The two sliding rods 9 are fixedly connected to two push plates 10 respectively. The movement of the sliding rods 9 can drive the movement of the push plates 10. At this time, damping force is generated under the action of the through hole 11, thereby effectively suppressing the vibration of the connecting rod 5 and the counterweight 12, so that the connecting rod 5 and the counterweight 12 can be quickly stabilized.

[0032] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the connecting mechanism includes two circular plates 27, both of which are fixedly sleeved on the outside of the rotating shaft 7. Two mounting shafts 15 for rotation are rotatably connected between the two circular plates 27. Two connecting pull plates 16 are fixedly sleeved on the outside of the two mounting shafts 15. The ends of the pull plates 16 away from the mounting shafts 15 are rotatably connected to the sliding rods 9 through the shaft body. When the connecting rod 5 and the counterweight 12 move, they will drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 will drive the circular plates 27 to rotate. The rotation of the circular plates 27 will drive the mounting shafts 15 to perform circumferential motion. Thus, under the action of the pull plates 16, the sliding rods 9 on both sides are pulled or pushed.

[0033] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the dial 3 is provided with a fixing bolt 17 for easy disassembly. The fixing bolt 17 is threadedly connected to the mounting bracket 2. The fixing bolt 17 makes it easy for the operator to disassemble the dial 3, thereby facilitating the selection of different scales of the dial 3 according to the measurement accuracy. The surface of the connecting rod 5 is provided with a through groove 13. A center plate 14 is fixedly connected inside the through groove 13. The through groove 13 and the center plate 14 make it easy for the operator to read the scale on the surface of the dial 3.

[0034] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a second cavity 18 is provided inside the vertical rod of the support frame 1. Two sliding blocks 20 are provided inside the second cavity 18. The ends of the two blocks 20 that are far apart from each other slide through the interior of the vertical rod of the support frame 1.

[0035] In addition, the shapes of the two card blocks 20 can be set as trapezoids with bevels or regular rectangles, without much restriction.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, two positioning grooves 21 are opened on the surface of the semi-ring 19. The two positioning grooves 21 are respectively adapted to the positions and specifications of the two locking blocks 20. The support frame 1 is fixedly sleeved with a support plate 26. The support plate 26 facilitates the support of the semi-ring 19. The second cavity 18 is provided with an unlocking mechanism.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the unlocking mechanism includes a drive shaft 23 for rotation, which is rotatably connected inside the second cavity 18. A transmission gear 24 is fixedly sleeved on the outside of the drive shaft 23. L-shaped toothed plates 22 for engaging with the transmission gear 24 are fixedly connected to the surfaces of both locking blocks 20. Both L-shaped toothed plates 22 are meshed with the transmission gear 24. Rotation of the drive shaft 23 drives the rotation of the transmission gear 24, which in turn drives the movement of the L-shaped toothed plates 22. The movement of the L-shaped toothed plates 22 then unlocks the locking blocks. The movement of block 20 allows the two locking blocks 20 to move closer to each other, causing them to disengage from the positioning groove 21. At this point, the mounting bracket 2 can be removed from the outside of the support frame 1. During installation, the above operation is repeated. First, the two locking blocks 20 are retracted into the inside of the support frame 1. Then, the semi-ring 19 is fitted onto the outside of the vertical rod of the support frame 1 and contacts the support plate 26. Subsequently, the positioning groove 21 and the locking blocks 20 are aligned. Then, the two locking blocks 20 are moved away from each other and locked into the inside of the positioning groove 21 to achieve the installation of the mounting bracket 2 and the semi-ring 19.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the upper end of the drive shaft 23 rotates through the upper surface of the vertical rod of the support frame 1. A knob 25 is fixedly connected to the upper end of the drive shaft 23, and the surface of the knob 25 is provided with an anti-slip groove. The knob 25 is designed to make it easy for the operator to hold and thus facilitates the operation of the drive shaft 23 to rotate.

[0039] The usage process of the mine inclination measuring instrument provided by this utility model is as follows:

[0040] First, when measuring the inclination angle, the staff places or fixes the support frame 1 on the bottom plate of the roadway to be measured. Then, the mounting frame 2 is fitted onto the outside of the vertical rod of the support frame 1 through the semi-ring 19. Since the two locking blocks 20 are located inside the support frame 1 in the initial state, the staff can use the semi-ring 19 to fit outside the vertical rod of the support frame 1 and contact the support plate 26, so that the positioning groove 21 and the locking block 20 are aligned. Then, by turning the knob 25, the drive shaft 23 is rotated. The drive shaft 23 drives the transmission gear 24 to rotate. The transmission gear 24 drives the two L-shaped toothed plates 22 that mesh with it to move away from each other, thereby moving the two locking blocks 20 away from each other, so that the locking blocks 20 are locked into the inside of the positioning groove 21. At this time, the mounting frame 2 and the semi-ring 19 can be fixed.

[0041] After the mounting bracket 2 is fixed, the connecting rod 5 and the counterweight 12 will hang down naturally under gravity. Due to airflow disturbances or vibrations caused by personnel operation in the underground environment, the connecting rod 5 and the counterweight 12 will swing. When the connecting rod 5 swings, since the connecting rod 5 is fixedly sleeved on the outside of the rotating shaft 7, it will drive the rotating shaft 7 to rotate inside the first cavity 6. When the rotating shaft 7 rotates, it will drive the two circular plates 27 fixedly sleeved on its outside to rotate synchronously. The two mounting shafts 15 rotatably connected between the two circular plates 27 will move with the circumference of the circular plates 27, and then the mounting shafts 15 will drive the pull plate 16 fixedly sleeved on its outside to move. Because the end of the pull plate 16 away from the mounting shaft 15 is rotatably connected to the sliding rod 9 through the shaft, the motion of the pull plate 16 is converted into the reciprocating linear motion of the sliding rod 9, and moves synchronously with the push plate 10 fixedly connected to its end. When the push plate 10 moves reciprocally inside the first cavity 6, it will repeatedly squeeze and suck in air through the through hole 11. During this process, the resistance generated when the air passes through the through hole 11 will form an effective damping force. This damping force acts in the opposite direction on the connecting rod 5 through the sliding rod 9, pull plate 16, mounting shaft 15, circular plate 27 and rotating shaft 7, thereby quickly suppressing the swing of the connecting rod 5 and the counterweight 12, and making them stop quickly.

[0042] After the weight 12 stabilizes, the staff can use the through groove 13 and center plate 14 on the surface of the connecting rod 5 to make accurate readings on the scale 3.

[0043] In addition, when the device needs to be stored, the operator can turn the knob 25 to rotate the drive shaft 23. The drive shaft 23 drives the transmission gear 24 to rotate, and the transmission gear 24 drives the two L-shaped toothed plates 22 that mesh with it to move closer to each other, thereby causing the two locking blocks 20 to retract into the second cavity 18, so that the locking blocks 20 are disengaged from the positioning groove 21. At this time, the mounting bracket 2 and the half ring 19 together with the dial 3 can be removed from the support frame 1, so that the operator can store the device as a whole.
