Description

Technical Field

[0001] This invention relates to the field of geological surveying technology, and in particular to an angular displacement reset device for a geological surveying instrument. Background Technology

[0002] Geological mapping is the process of surveying and mapping geological information within a certain area using specialized measurement methods. This results in the acquisition of geological and geomorphological information for that area, which is then applied to various fields. It is of great significance for geological mapping, engineering design, and disaster prevention. Surveying instruments are generally used in geological mapping. When an angular displacement deviation occurs during the use of a surveying instrument, a reset device is used to restore it to the correct angular displacement state to ensure the accuracy and reliability of the mapping results.

[0003] Existing angular displacement reset devices are rudimentary in structure and limited in function. During use, the angular displacement distance cannot be directly and accurately observed, making it impossible to accurately determine the reset position during subsequent resets. Furthermore, when reset is achieved through spring deformation, prolonged use can lead to spring deformation errors, resulting in poor reset accuracy. Therefore, designing an angular displacement reset device for geological mapping instruments is essential. Summary of the Invention

[0037] Working principle: During use, after the assembly base 7 and the surveying tripod are installed and fixed, the surveying instrument is installed and fixed inside the equipment base 9. As the surveying instrument performs surveying work, it drives the first displacement shaft 3 to rotate at the center of the end face of the rotating bracket 2, causing the first displacement shaft 3 and the reset component 4 to rotate and adjust, thereby changing the angular displacement of the surveying instrument. After the surveying is completed, the reset component 4 can be used to adjust the first displacement shaft 3 and the equipment base 9 to reset, so that the surveying instrument on the top of the equipment base 9... The equipment is reset for convenient subsequent measurements; the first displacement shaft 3 has a stable rotation effect at the center of the end face of the transmission bearing 41 and the second transmission end cover 42, and can drive the transmission gear 43 to rotate. When the transmission gear 43 rotates, since the transmission gear 43 is meshed with the follower gear frame 410, the rotation of the transmission gear 43 can push the follower gear frame 410 to drive the first guide rail slide 46 to move on the surface of the first electric guide rail 45, so that the positioning magnetic block 48 inside the positioning groove 47 is misaligned with the electromagnetic locking tongue 413 on one side of the electromagnetic base 412. When the moving gear frame 410 moves, it can drive the displacement indicator frame 414 to move on the surface of the displacement scale plate 415, thereby facilitating the display of the angular displacement distance through the movement distance. The guide block 49 on the inner side of the fixed frame 44 slides relative to the guide groove 411 on the outer side of the following gear frame 410, which can limit the movement of the following gear frame 410. When a reset is required, the first electric guide rail 45 and the electromagnetic base 412 inside the fixed frame 44 work, driving the following gear frame 410 to move in the opposite direction through the first guide rail slide 46, and the electromagnetic base 412 The electromagnetic locking tongue 413 can achieve the effect of magnetic attraction and fixation. During the movement of the first guide rail slide 46, when the positioning magnetic block 48 inside the positioning groove 47 moves to the outside of the electromagnetic locking tongue 413, the electromagnetic locking tongue 413 is magnetically attracted and fixed to the positioning groove 47. By magnetically attracting and fixing the two electromagnetic locking tongues 413 to the two positioning magnetic blocks 48, the first electric guide rail 45 stops working, thereby stopping the first guide rail slide 46. It is also convenient to observe the position of the displacement indicator 414 on the outside of the displacement scale plate 415, so as to determine the accuracy of the reset.To facilitate surveying, the second displacement shaft 6 on the outer side of the mounting base 1 rotates with the first transmission end cover 5 on the inner side of the assembly base 7, allowing the angle of the mounting base 1 to be adjusted. The angle of the mounting base 1 can be reset and adjusted via the balancing assembly 8. The second electric guide rail 81 operates, and the crossbeam frame 83 is moved to a suitable height via the second guide rail slide 82. Based on the tilt angle of the mounting base 1, the second electric cylinders 87 at both ends of the reset support plate 86 operate, and the position of the extension support plate 89 can be adjusted via the second piston rod 88, allowing the extension support plate 89 to... The device moves to directly beneath the inclined portion of the mounting base 1. Simultaneously, the first electric cylinder 84 on the end face of the crossbeam frame 83 operates, adjusting the height of the reset support plate 86 and the extension support plate 89 via the first piston rod 85. This allows the extension support plate 89 to contact the end face of the inclined portion of the mounting base 1. As the extension support plate 89 and the reset support plate 86 continuously rise, the second displacement shaft 6 on the outer side of the mounting base 1 rotates with the first transmission end cover 5, facilitating the reset and straightening of the mounting base 1. This makes it convenient for the surveying instrument on top of the equipment base 9 to perform subsequent surveying.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
