Description

Technical Field

[0001] This utility model mainly relates to the field of field surveying auxiliary equipment, specifically a positioning device for a surveying instrument used in field geological exploration. Background Technology

[0002] In the process of topographic surveying in the field, it is necessary to measure the height difference between two points on the ground, the distance between two points on the ground, and the tilt angle between two points on the ground. In order to accurately measure the height difference, distance, and tilt angle between two points on the ground, a total station is needed for auxiliary measurement. The total station is an auxiliary surveying instrument that integrates the functions of measuring horizontal angle, vertical angle, distance, and height difference. In the process of topographic surveying in engineering field surveying, the total station is an indispensable auxiliary equipment.

[0003] Existing total stations are generally mounted on tripods. However, current tripods often struggle to provide stable horizontal support on uneven or sloping ground, limiting the operation of the total station. Surveyors frequently need to excavate a flat surface on-site to ensure smooth surveying operations. However, this presents significant operational difficulties on steep slopes, creating considerable obstacles and challenges for land surveying personnel. Therefore, this paper proposes a surveying device for field exploration projects to address these issues. Utility Model Content

An instrument connecting seat 8 is fixedly provided on the upper part of the turntable 7, so that the surveying device can be fixed on the instrument connecting seat 8 and can rotate with the turntable 7 to achieve the purpose of omnidirectional surveying.

[0024] Three rotating seats 9 are provided on the upper surface of the chassis 1 at an included angle. A rotating disk 10 is provided on the upper part of the rotating seat 9 and is rotatably connected to it, so that the device on the rotating disk 10 can rotate with the rotating disk 10. A connecting seat 11 is provided on the upper part of the rotating disk 10. A rotating shaft hole 12 is opened on the connecting seat 11. A rotating shaft 13 is provided inside the rotating shaft hole 12. Rotating tubes 14 are provided on both sides of the rotating shaft 13 and are fixedly connected to it, so that the rotating tubes 14 can rotate relative to the connecting seat 11 to achieve the purpose of adjusting the angle. An extension rod 15 is provided inside each of the rotating tubes 14 and is slidably connected to it, so that the length of the extension rod 15 can be adjusted inside the rotating tube 14.

[0025] A sliding sleeve 16 is fitted onto the support rod 5 and slidably connected thereto. Three spherical connecting seats 17 are fixedly arranged at equal intervals around the sliding sleeve 16. A spherical connecting seat 17 has a spherical body 18 inside and is rotatably connected thereto. The spherical body 18 is fixedly connected to the end of the extension rod 15, so that the extension rod 15 is connected to the spherical connecting seat 17, and the position of the extension rod 15 can be freely adjusted in the spherical connecting seat 17, which is used to assist the support rod 5 in changing its angle and to support it.

[0026] The upper surface of the chassis 1 has three rotating holes 19 at an included angle. A rotating rod 20 is rotatably connected to each rotating hole 19. The rotating rod 20 rotates itself and penetrates the ground to fix the chassis 1 to the ground. A fixing ring 21 is fixedly fitted onto each rotating rod 20. Two fixing rings 21 are fitted onto each rotating rod 20, and the fixing rings 21 are located on the upper and lower sides of the chassis 1 and slidably connected to them, for fixing the rotating rod 20. A knob 22 is fixedly fitted at the upper end of the rotating rod 20 for rotating the rotating rod 20. A cone 23 is fixedly fitted at the lower end of the rotating rod 20 to make it easier for the rotating rod 20 to penetrate the ground and fix the chassis 1. A positioning rod 24 is fixedly fitted at the center of the bottom surface of the chassis 1. A cone 25 is fixedly fitted at the bottom of the positioning rod 24.

[0029] Working principle:

[0030] In use, this device locates the survey point and positions it by inserting the positioning rod 24 into the ground. Further, the rotating rod 20 around the base 1 is rotated to penetrate deeper into the ground, fixing the base 1 in place. Then, the angle of the support rod 5 is changed by altering the position of the sphere at the support end relative to the spherical connecting seat 3, making it perpendicular to the ground. The support rod 5 is supported by the interaction between the rotating disk 10, the rotating rod 20, the extension rod 15, the second sphere 18, and the second spherical connecting seat 17. The support rod 5 is fixed in a vertical position by the fixing devices on the rotating rod 20 and the sliding sleeve 16, facilitating subsequent surveying work. The surveying device is connected to the instrument connecting seat 8, allowing it to rotate with the turntable 7 to adjust the surveying orientation, thus facilitating personnel surveying work. This device has a simple structure, is easy to use, and is suitable for widespread application.
