DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a protective tripod device for mine measurement, including a support seat 4, and a top seat 2 is rotatably connected to the top of the support seat 4, and the support seat 4 and the top seat 2 are connected through a bearing, so that the support seat 4 and the top seat 2 can be rotated. When in use, the measuring instrument is installed on the top of the top seat 2, and the measuring instrument can be rotated 360 degrees when in use. Figure 1 As shown, in order to facilitate the rotation adjustment of the top seat 2, a handle 1 is fixedly connected to the outer wall of the top seat 2. Pushing the handle 1 can drive the top seat 2 to rotate on the top of the support seat 4. A pointer 3 extending downward is fixedly connected to the lower end of the outer wall of the top seat 2. A scale 14 is provided on the outer wall of the support seat 4. With the cooperation of the pointer 3 and the scale 14, the rotation adjustment angle can be judged. In order to facilitate the observation of the scale 14, the top seat 2 and the support seat 4 are both configured to be truncated cones.

[0021] At the same time, in order to meet the measurement requirements of different heights, the bottom of the support seat 4 is connected to the base 13 through a lifting mechanism. A mounting groove 11 is provided on the top of the base 13. A support plate 10 is rotatably connected to the mounting groove 11 through a rotating shaft. The lifting mechanism is fixedly connected to the top of the support plate 10.

[0022] like Figure 1 As shown, the lifting mechanism includes a second sleeve 21 vertically connected to the top of the support plate 10, and a second guide rod 8 is vertically connected to the bottom of the support seat 4. The bottom of the second guide rod 8 extends into the second sleeve 21. The second guide rod 8 is lifted and pulled in the second sleeve 21, and the height formed between the two can be adjusted to a suitable position. In order to quickly fix them, the second sleeve 21 and the second guide rod 8 are locked by a locking bolt 6. The operation is simple and practical.

[0023] At the same time, in order to further ensure the stable sliding adjustment of the support seat 4 and the top seat 2, as Figure 1As shown, a first sleeve 7 is symmetrically connected along the second sleeve 21 at the top of the support plate 10, and a first guide rod 5 is correspondingly connected to the bottom of the support seat 4. The bottom of the first guide rod 5 extends into the first sleeve 7. In actual use, a return spring is installed at the bottom of the first guide rod 5. The support seat 4 drives the first guide rod 5 to slide in the first sleeve 7 during lifting and lowering adjustment. The first guide rod 5 generates pressure on the return spring. Under the pressure of the spring, not only the guidance of the adjustment is achieved, but also the stability of the placement of the support seat 4 and the top seat 2 is guaranteed, and the bottom of the first guide rod 5 is prevented from slipping out of the first sleeve 7. An annular plate for limiting is installed on the top of the first sleeve 7.

[0024] like Figure 3 , 4 As shown, in order to facilitate the rotation adjustment of the support plate 10 along the rotating shaft, a mounting cavity 22 connected to the mounting groove 11 is provided at the bottom of the base 13, and the diameter of the mounting groove 11 is smaller than the inner diameter of the mounting cavity 22. The base 13 is symmetrically connected with adjusting bolts 9. The straight line where the adjusting bolts 9 are located is perpendicular to the straight line position where the rotating shaft is located. The bottom of the adjusting bolts 9 extends into the mounting cavity 22 and the outer wall is threadedly connected with a mounting seat 18. When installing, a nut for limiting is connected to the bottom of the adjusting bolts 9 to prevent the mounting seat 18 from falling off. The bottom of the support plate 10 is symmetrically provided with a connection rotatably connected thereto. Rod 16, the other end of the connecting rod 16 is rotatably connected to the mounting seat 18, a slide rail 20 is fixedly connected to the inner wall of the mounting cavity 22, and a slider 19 is fixedly connected to the outer wall of the mounting seat 18. The slider 19 is cooperatively connected with the slide rail 20. When the placement angle of the support plate 10 needs to be adjusted, the adjusting bolt 9 is rotated to move up and down. Since the connecting rod 16 is rotatably connected to the mounting seat 18 and the support plate 10, the placement angle of the support plate 10 can be fine-tuned, which can meet the use of the measuring instrument on different support surfaces, ensure the horizontal placement of the instrument, and thus ensure the measurement accuracy.

[0025] like Figure 3 , 4 As shown, in order to ensure the normal rotation of the connecting rod 16, an articulated seat 15 is fixedly connected to the bottom of the support plate 10 and the outer wall of the mounting seat 18, and the end of the connecting rod 16 is rotatably connected to the articulated seat 15 at the corresponding position. At the same time, in order to facilitate the user to push and use the device, a universal wheel 12 is fixedly connected to the bottom of the base 13, and the universal wheel 12 is a brake universal wheel, which can save the user's manpower when transporting the device. After placing the device in the use position, the device can be locked and fixed by the brake function. When in use, a counterweight block 17 is fixedly connected to the bottom of the base 13 to lower the center of the entire device and improve the stability of the device.

[0026] To sum up, when using the protective tripod device for mine measurement, the device is placed at the use position, the position of the device is fixed by the brake universal wheel, and the measuring instrument is installed on the top of the top seat 2. Due to different measuring environments, the device is very easy to be placed on different support surfaces. The adjusting bolt 9 is rotated and adjusted, so that the support plate 10 can be rotated and adjusted along the rotating shaft, and a level ruler 23 for observation is installed on the top of the support plate 10, so that the device can be quickly adjusted horizontally. By sliding and pulling the support seat 4 to drive the second guide rod 8 to slide in the first sleeve 7, the height adjustment of the measuring instrument can be achieved. At the same time, the top seat 2 is rotated to achieve the horizontal rotation adjustment of the measuring instrument. The utility model not only meets the use of the support legs on different support surfaces, but also can achieve horizontal adjustment. It has a simple structure and is easy to operate, which effectively improves the practicality of the device.
