[0002] During the construction and production process of open-pit mines, a series of surveying work needs to be carried out. These surveying work carried out in conjunction with open-pit mining is collectively referred to as open-pit mine surveying. Surveying instruments are commonly used tools in open-pit mine surveying. Surveying instruments are instruments and devices designed and manufactured for surveying operations to collect, process, and output data. In open-pit mining projects, orientation, distance measurement, angle measurement, and height measurement are required at the mining site. Therefore, surveying instruments are needed to assist construction personnel in data measurement. Usually, surveying instruments need to be supported by brackets and erected on the ground.

[0003] However, the support frame used to support the surveying instrument realizes rotation and angle adjustment through the rotating shaft connected to the top. Since the rotating shaft at the top of the support frame can always rotate, the stability of the support frame is not high enough and it is easy to tip over. Therefore, the safety and comfort of use are not high enough. In addition, during transportation, the rotation of the rotating shaft can easily cause the support frame to spread out, which is not conducive to the transportation of the surveying and mapping device. Utility Model Content

[0004] The purpose of the present utility model is to provide an open-pit mining area topographic mapping device in order to solve the above-mentioned problems. By engaging the insertion rod on the connecting plate with the limiting hole on the rotating shaft so that the rotating shaft no longer rotates, the supporting structure is fixed, thereby increasing the stability of the supporting structure, making the surveying device safer and more comfortable during use, flexible and convenient to operate, facilitating the use and transportation of the surveying device, and improving work efficiency.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-8As shown in the figure, a topographic surveying device for open-pit mining areas includes a mounting base 1. Three rotating shafts 5 are rotatably connected to the mounting base 1. Fixed sleeves 2 are fixedly connected to the three rotating shafts 5. A support structure 3 is installed on the fixed sleeves 2. A limiting structure 4 is installed on the mounting base 1. The limiting structure 4 includes a spring 403. The top surface of the mounting base 1 is fixedly connected to the spring 403. The other end of the spring 403 is fixedly connected to the bottom end of a connecting plate 401. Eight insertion rods 404 are fixedly connected to the bottom end of the connecting plate 401. A plurality of limiting holes 405 are circumferentially arranged at both ends of the rotating shaft 5. The insertion rods 404 are engaged with adjacent limiting holes 405. A second sliding rod 402 is fixedly connected to the bottom end of the connecting plate 401. The second sliding rod 402 penetrates through the mounting base 1. A second sliding sleeve 408 is fixedly connected to the bottom end of the mounting base 1. The second sliding rod 402 is slidably connected to the second sliding sleeve 408. A second screw rod 409 is rotatably connected to the bottom end of the second sliding sleeve 408. The second screw rod 409 is threadedly connected to the second sliding rod 402. A surveying instrument 6 is installed at the top end of the connecting plate 401; First, hold one of the first sliding rods 301 and pull it outwards. The first sliding rod 301 drives the rotating shaft 5 to rotate. Adjust the first sliding rod 301 to a suitable angle. Then, adjust the angles of the first sliding rods 301 on the other two rotating shafts 5 in sequence, so that the support structure 3 is erected on the ground and can support the surveying instrument 6. Then, press down the connecting plate 401. The connecting plate 401 drives the insertion rods 404 to move downwards until the insertion rods 404 are engaged with adjacent limiting holes 405. When the connecting plate 401 moves downwards, it drives the spring 403 to contract and drives the second sliding rod 402 to slide into the interior of the second sliding sleeve 408 until the bottom end of the second sliding rod 402 abuts against the inner wall of the second sliding sleeve 408. Then, rotate the second screw rod 409 to connect the second screw rod 409 to the second sliding rod 402, thereby fixing the second sliding rod 402 and further fixing the connecting plate 401, so that the connecting plate 401 cannot drive the insertion rods 404 to slide upwards, increasing the stability of the insertion rods 404 in limiting the rotating shaft 5, thereby increasing the stability of the support structure 3, making the surveying device safer and more comfortable during use, flexible and convenient to operate, facilitating the use and handling of the surveying device, and improving work efficiency.

[0025] As a technical optimization solution of the present utility model, three guide rods 406 are fixedly connected to the bottom end of the connecting plate 401. The three guide rods 406 are slidably connected to the mounting seat 1. An anti - detachment block 407 is installed at the bottom end of the guide rod 406, and the anti - detachment block 407 abuts against the mounting seat 1 upward. When the connecting plate 401 moves downward, the guide rod 406 slides on the mounting seat 1. The arrangement of the guide rod 406 has a guiding effect on the insertion rod 404. And when the spring 403 resets and drives the second slide rod 402 and the connecting plate 401 to move upward, the guide rod 406 slides upward, driving the anti - detachment block 407 to move upward. The anti - detachment block 407 abuts against the bottom end of the mounting seat 1, thereby preventing the second slide rod 402 from slipping off the mounting seat 1, causing the connecting plate 401 to drive the surveying instrument 6 to slip off, and increasing the stability of the connecting plate 401 and the surveying instrument 6.

[0026] As a technical optimization solution of the present utility model, the three rotating shafts 5 are arranged in a circumferential array, and the three rotating shafts 5 form a triangular structure. The three rotating shafts 5 forming a triangular structure increases the stability of the support structure 3.

[0027] As a technical optimization solution of the present utility model, the support structure 3 includes a first slide rod 301. Two first slide rods 301 are fixedly connected to the fixed sleeve 2. The two first slide rods 301 are slidably connected to the same first slide sleeve 302. A support rod 303 is fixedly connected to the first slide sleeve 302. A first screw rod 305 is slidably connected to the first slide sleeve 302, and the end of the first screw rod 305 abuts against one of the first slide rods 301. When the ground is uneven and the support structure 3 needs to be leveled, rotate one of the first screw rods 305 so that the end of the first screw rod 305 does not abut against the first slide rod 301, and then slide the first slide sleeve 302 downward. The first slide sleeve 302 drives the support rod 303 to move downward until the support plate 304 at its bottom end abuts against the ground, so that all three support plates 304 abut against the ground, thereby making the support of the support structure 3 for the surveying instrument 6 more stable and making the use of the surveying device more convenient and flexible.

[0028] As a technical optimization solution of the present utility model, a support plate 304 is fixedly connected to the bottom end of the support rod 303. The support plate 304 is in a rectangular structure. The arrangement of the support plate 304 increases the contact area between the support rod 303 and the ground, makes the friction between the support rod 303 and the ground larger, and the support more stable.

[0029] When the utility model is in use, first hold one of the first sliding rods 301 and pull the first sliding rod 301 outwards. The first sliding rod 301 drives the rotating shaft 5 to rotate, and adjust the first sliding rod 301 to an appropriate angle. Then, adjust the angles of the first sliding rods 301 on the other two rotating shafts 5 in turn, so that the support structure 3 is erected on the ground and can support the surveying instrument 6. Then, press down the connecting plate 401. The connecting plate 401 drives the insertion rod 404 to move downwards until the insertion rod 404 is engaged in the adjacent limiting hole 405. When the connecting plate 401 moves downwards, it drives the spring 403 to contract and drives the second sliding rod 402 to slide into the interior of the second sliding sleeve 408 until the bottom end of the second sliding rod 402 abuts against the inner wall of the second sliding sleeve 408. Then, rotate the second screw rod 409 to connect the second screw rod 409 with the second sliding rod 402, thereby fixing the second sliding rod 402, and further fixing the connecting plate 401, so that the connecting plate 401 cannot drive the insertion rod 404 to slide upwards, increasing the stability of the insertion rod 404 in limiting the rotating shaft 5, thereby increasing the stability of the support structure 3, making the surveying device safer and more comfortable in use, more flexible and convenient in operation, facilitating the use and handling of the surveying device, and improving work efficiency; when the connecting plate 401 moves downwards, the guide rod 406 slides on the mounting seat 1. The arrangement of the guide rod 406 has a guiding effect on the insertion rod 404. And when the spring 403 resets and drives the second sliding rod 402 and the connecting plate 401 to move upwards, the guide rod 406 slides upwards, driving the anti - detachment block 407 to move upwards. The anti - detachment block 407 abuts against the bottom end of the mounting seat 1, thereby preventing the second sliding rod 402 from slipping off the mounting seat 1, resulting in the connecting plate 401 driving the surveying instrument 6 to slip off, and increasing the stability of the connecting plate 401 and the surveying instrument 6; when the ground is uneven and the support structure 3 needs to be leveled, rotate one of the first screw rods 305 so that the end of the first screw rod 305 does not abut against the first sliding rod 301. Then, slide the first sliding sleeve 302 downwards. The first sliding sleeve 302 drives the support rod 303 to move downwards until the support plate 304 at its bottom end abuts against the ground, so that all three support plates 304 abut against the ground, making the support of the support structure 3 for the surveying instrument 6 more stable and making the use of the surveying device more convenient and flexible; after the support structure 3 is adjusted, install the surveying instrument 6 on the connecting plate 401 through bolts.
