Description

Technical Field

[0001] This utility model belongs to the field of tunnel measurement technology, and more specifically, relates to a mine tunnel measurement system. Background Technology

[0002] Currently, the common practice is to set up traverse points on the roof of the roadway and suspend a plumb bob by a plumb line to center the total station at the top center point. However, setting up traverse points on the roof of the roadway is complicated, and it is difficult to stabilize the swing of the plumb line and the plumb bob. The centering error is generally larger than that of centering on the floor, and the measurement accuracy is difficult to control.

[0003] Furthermore, the lack of lighting or insufficient lighting in underground roadways makes total station surveying in underground roadways quite difficult. Finding points is challenging, and it is extremely difficult to locate the required traverse points in poorly lit roadways. Centering the total station is troublesome, and it is difficult to accurately aim at the target using forward and backward sights. In the absence of light, the laser rangefinder of the total station also has difficulty returning, and the rangefinder response is slow. If the mine lamp carried by the total station is used for supplemental lighting, it is difficult to align the position, and adjustments are extremely troublesome. Utility Model Content

[0029] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0031] Reference Figures 1 to 3 As shown, a mine roadway measurement system includes a total station 1, illumination lamps 2, and multiple traverse points. The number of illumination lamps 2 is the same as the number of traverse points and they correspond one-to-one.

[0032] The traverse points are divided into permanent traverse points 3 and temporary traverse points 4. Permanent traverse points 3 are located at the top of the tunnel, and temporary traverse points 4 are located at the bottom of the tunnel. The number of temporary traverse points 4 is greater than the number of permanent traverse points 3.

[0033] Total station 1 is set up at one of the temporary traverse points 4;

[0034] The traverse points are divided into permanent traverse points 3 and temporary traverse points 4. Permanent traverse points 3 are set at the top of the roadway, which is relatively stable and is usually set in some important locations. Temporary traverse points 4 are set at the bottom of the roadway, which is simpler and more convenient to set up. The total station 1 can complete the centering and measurement by coordinating permanent traverse points 3 and temporary traverse points 4.

[0035] Furthermore, each guide point is equipped with an illumination lamp 2, which is placed at the bottom of the tunnel. The illumination direction of the illumination lamp 2 is adjustable, making it very convenient to adjust and providing good supplementary lighting.

[0036] In this embodiment, a forward-looking target prism 5 is provided on a temporary traverse point 4 adjacent to the total station 1, and a back-looking target 6 is provided on another temporary traverse point 4 adjacent to the total station 1. Both the forward-looking target prism 5 and the back-looking target 6 are used to cooperate with the total station 1 to facilitate measurement.

[0037] The illumination lamps 2 corresponding to these temporary guide points 4 are for supplemental lighting of the equipment, namely, for the total station 1, the forward target prism 5, and the back sight target 6.

[0038] In this embodiment, the guide points are generally marked with cross steel nails. The illumination lamp 2 of the permanent guide point 3 and the illumination lamp 2 of the temporary guide point 4 without equipment are both illuminated on the cross steel nails, which makes it easy to find the guide points.

[0039] The corresponding guide point number can be written on the side wall of the tunnel. When there is no measurement task, each illumination lamp 2 can shine on the number to facilitate finding the guide point next time.

[0040] In this embodiment, it includes a base plate 21, a mounting bracket 22 and a rechargeable lamp head 23. The mounting bracket 22 is fixed on the base plate 21, and a swing plate 24 is rotatably mounted on the mounting bracket 22. The rotation axis of the swing plate 24 extends in the horizontal direction.

[0041] A first screw 25 is threaded through the swing plate 24, and a rechargeable lamp head 23 is fixed on the first screw 25. The first screw 25 is rotated to adjust the illumination direction of the rechargeable lamp head 23.

[0042] An adjustment mechanism 26 is provided on the base plate 21. The adjustment mechanism 26 is connected to the end of the first screw 25 away from the rechargeable lamp head 23 to adjust the angle between the swing plate 24 and the base plate 21, thereby adjusting the illumination direction of the rechargeable lamp head 23.

[0043] The base plate 21 can be placed directly on the ground, making the arrangement of the illumination lamp 2 simple. By rotating the first screw 25 and controlling the tilt of the swing plate 24, the illumination direction of the rechargeable lamp head 23 can be adjusted in multiple directions to provide supplementary lighting and assist the total station 1 in measurement. After the measurement is completed, the illumination lamp 2 can be taken away directly without affecting the passage of the tunnel.

[0044] In this embodiment, in order to ensure the stability of the rechargeable lamp head 23, the base plate 21 is made of stainless steel, which is relatively heavy and will not wobble; therefore, the rechargeable lamp head 23 can adjust the illumination direction in multiple directions, and the rechargeable lamp head 23 can illuminate a specific position without moving the base plate 21.

[0045] In this embodiment, the swing plate 24 is provided with a through threaded hole, and the first screw 25 is threadedly connected to the threaded hole and passes through the threaded hole. Therefore, by rotating the first screw 25, the illumination direction of the rechargeable lamp head 23 can be changed.

[0046] The swing plate 24 is hinged to the mounting bracket 22 on both sides along the axial direction of the threaded hole, ensuring that the rotation direction of the swing plate 24 is different from the rotation direction of the first screw 25, so as to realize the multi-directional adjustment of the rechargeable lamp head 23.

[0047] In this embodiment, the adjustment mechanism 26 includes a fixed frame 261 and a movable rod 262. The movable rod 262 can be elastically raised and lowered. The fixed frame 261 is provided with a second screw 263. The second screw 263 is located above the movable rod 262 and opposite to the movable rod 262. The second screw 263 cooperates with the movable rod 262 to clamp the end of the first screw 25 away from the rechargeable lamp head 23.

[0048] Rotating the second screw 263 adjusts its height, thereby adjusting the height of the end of the first screw 25 furthest from the rechargeable lamp head 23. The first screw 25 then rotates the swing plate 24, adjusting its tilt angle. The movable rod 262 extends and retracts accordingly, allowing it to continuously engage with the second screw 263 to clamp the first screw 25. When the measuring personnel do not rotate the first screw 25, it will not loosen and affect the posture of the rechargeable lamp head 23. Therefore, in addition to adjusting the illumination direction of the rechargeable lamp head 23, the adjustment mechanism 26 also prevents the first screw 25 from loosening, making the posture of the rechargeable lamp head 23 more stable.

[0049] In this embodiment, the top of the movable rod 262 is provided with a first elastic block 264, and the bottom of the second screw 263 is provided with a second elastic block 265. Both the first elastic block 264 and the second elastic block 265 are in contact with the first screw 25. The elastic blocks can press the first screw 25 tightly, thereby preventing the first screw 25 from loosening. However, the first screw 25 can be rotated and adjusted under manual rotation or when the rod is pressed down.

[0050] In this embodiment, both the first elastic block 264 and the second elastic block 265 are provided with arc-shaped notches. The arc-shaped notches can adapt to the outer periphery of the first screw 25. Of course, when the first screw 25 is tilted, the arc-shaped notches cannot completely fit the outer periphery of the first screw 25. However, relying on the elastic properties, most of the arc-shaped notches can contact the outer periphery of the first screw 25 and play a pressing role.

[0051] In this embodiment, the movable rod 262 includes a fixed sleeve 2621, a movable sleeve 2622, and a spring. The fixed sleeve 2621 is fixed on the base plate 21, the movable sleeve 2622 is sleeved on the fixed sleeve 2621, and the spring passes through the fixed sleeve 2621. The spring is supported between the base plate 21 and the movable sleeve 2622 so that the movable sleeve 2622 can be elastically raised and lowered. The first elastic block 264 is fixed on the top of the movable sleeve 2622.

[0052] Of course, using other flexible telescopic rods is also feasible.

[0053] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
