[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] like Figures 1 to 4 The figure shows a tripod for mining engineering surveying according to the present invention, comprising a support platform 1, hinged at the bottom of which are three telescopic frames 2 arranged in a circular array. The bottoms of the telescopic frames 2 are provided with a ground insertion assembly 3, which includes a connecting lug 31. The upper portion of the connecting lug 31 is hingedly connected to the bottom of the telescopic frame 2 via a pin 4. A first insertion rod 32 is fixed to the lower portion of the connecting lug 31, and a second insertion rod assembly 33 is slidably sleeved on the outer side of the first insertion rod 32.

[0025] The telescopic frame 2 is used to adjust the length and level of the tripod. It includes a fixed rod 21 and a movable rod 22 slidably connected to the fixed rod 21. The fixed rod 21 and the movable rod 22 are securely connected by an adjustment bolt 23. The top of the fixed rod 21 is hinged to the bottom of the support platform 1, and the bottom of the movable rod 22 is hinged to the connecting lug 31. The height of the telescopic frame 2 is adjusted by adjusting the relative position of the fixed rod 21 and the movable rod 22. Once the relative positions of the fixed rod 21 and the movable rod 22 are adjusted, the two are securely connected by tightening the adjustment bolt 23. Of course, if the distance between the fixed rod 21 and the movable rod 22 needs to be adjusted, it is necessary to loosen the adjustment bolt 23 and allow the two to slide relative to each other. In this embodiment, each telescopic frame 2 is equipped with two adjustment bolts 23, one for backup and one for improved stability. The telescopic frame 2 is conventional, and its detailed structure and operating principle are not described here in detail.

[0026] like Figures 2 to 4As shown, a first insertion rod 32 is fixed to the lower part of the connecting ear 31. The first insertion rod 32 is vertically arranged, has a columnar structure, and has a conical structure at the bottom, which makes it easier to insert the first insertion rod 32 into the ground.

[0027] like Figures 2 to 4 As shown, a second rod assembly 33 is slidably mounted on the outer side of the first rod 32. The second rod assembly 33 comprises a first sleeve 331 slidably mounted on the upper portion of the first rod 32. A second sleeve 332 is rotatably mounted on the outer portion of the first sleeve 331. The first rod 32, first sleeve 331, and second sleeve 332 are coaxially arranged. Specifically, two first protrusions 3321 are projecting inward from the middle of the inner wall of the second sleeve 332. The two first protrusions 3321 are positioned opposite each other, and the inner wall of the first protrusions 3321 has an arcuate surface. The outer wall of the first sleeve 331 is formed with an annular groove 3311 and two vertical first slide grooves 3312. The annular groove 3311 is connected to the two first slide grooves 3312, and the annular groove 3311 and the two first slide grooves 3312 are both corresponding to the first protrusions 3321. When installing the second sleeve 332 with the first sleeve 331, the two first protrusions 3321 on the second sleeve 332 are aligned with the two first sliding grooves 3312 on the first sleeve 331 respectively. After the first protrusion 3321 slides downward in the first sliding groove 3312 to the annular groove 3311, the first protrusion 3321 can rotate freely in the annular groove 3311, thereby allowing the second sleeve 332 to rotate 360 ​​degrees outside the first sleeve 331 without the two being separated.

[0028] A foot pedal 333 is fixedly connected to one side of the second sleeve 332. The foot pedal 333 is arranged horizontally and has a trapezoidal structure. The smaller end of the foot pedal 333 is fixedly connected to the outer wall of the second sleeve 332, and the larger end of the foot pedal 333 extends away from the second sleeve 332, making it easier for the user to step on it. A downward-inclined auxiliary rod 334 is fixedly provided at the bottom of the foot pedal 333. The auxiliary rod 334 has a conical structure. The large-diameter end of the auxiliary rod 334 is fixedly connected to the bottom of the foot pedal 333, and the small-diameter end of the auxiliary rod 334 extends downward. Four ridges 3341 that taper from top to bottom are evenly distributed around the outer circumference of the auxiliary rod 334. The provision of the ridges 3341 makes it easier for the auxiliary rod 334 to be more stable when inserted into the ground. When the second sleeve 332 rotates outside the first sleeve 331 , the second sleeve 332 drives the pedal 333 and the auxiliary insertion rod 334 fixedly connected thereto to rotate synchronously, so that the auxiliary insertion rod 334 rotates to a position where it needs to be inserted.

[0029] The inner wall of the first sleeve 331 is provided with three vertical second protrusions 3313. The three second protrusions 3313 are evenly distributed along the circumference of the first sleeve 331, and the length direction of the second protrusions 3313 is arranged parallel to the axial direction of the first sleeve 331. Three second sliding grooves 321 are correspondingly defined on the upper outer periphery of the first insertion rod 32. The three second protrusions 3313 slide in the three second sliding grooves 321, thereby enabling the first sleeve 331 to reciprocate along the axial direction of the first insertion rod 32. An annular baffle 322 is fixedly provided in the middle of the first insertion rod 32, and a spring 34 is sleeved on the outer side of the first insertion rod 32. One end of the spring 34 is fixedly connected to the top of the annular baffle 322, and the other end is fixedly connected to the bottom of the first sleeve 331. The spring 34 is provided to limit the distance between the first sleeve 331 and the first insertion rod 32.

[0030] When using the tripod for mining engineering surveying of the present invention, move the tripod to the designated position, loosen the adjusting bolt 23, make the fixed rod 21 and the movable rod 22 slide relative to each other to the set position, tighten the adjusting bolt 23, rotate each telescopic frame 2 to open it to a certain angle, and insert the three first insertion rods 32 into the ground. If the ground is soft and the tripod is prone to shaking and instability, rotate the second sleeve 332 to drive the foot pedal 333 and the auxiliary insertion rod 334 fixed thereto to rotate to the position where they need to be inserted, and press the foot pedal 333 with force. As the foot pedal 333 moves downward, it drives the second sleeve 332, first sleeve 331, and auxiliary rod 334, which are fixed to it, downward. The spring 34 is compressed, further pressing the foot pedal 333 until the auxiliary rod 334 is also inserted into the ground. Because the auxiliary rod 334 is tilted and has multiple ridges 3341, it can be inserted into the ground in a different direction than the vertical first rod 32. The combination of the two greatly enhances the fastening force between the telescopic frame 2 and the ground, ensuring the stability of the tripod's connection to the ground. After the tripod is set up, the measuring instrument is fixed to the support platform 1 and leveled before the measurement operation can begin.

[0031] Although the present invention discloses preferred specific embodiments to achieve the above-mentioned objectives, it is not intended to limit the structural features of the present invention. Any person skilled in the art should know that within the technical spirit of the present invention, any easily conceivable changes or modifications are possible and are all covered by the scope of the patent application of the present invention.
