Description

Technical Field

[0001] This invention relates to the field of land surveying technology, and in particular to a land surveying device with anti-interference and stability. Background Technology

[0002] Engineering surveying is crucial in the planning, design, construction, and operation management stages of engineering projects. It involves various surveying tasks and requires equipment such as theodolites, levels, plane tables, laser measuring instruments, and electromagnetic distance measuring instruments. Among these, the use of levels and theodolites generally requires five steps: instrument setup, rough leveling, aiming, fine leveling, and reading.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: As a key surveying tool, the core function of a leveling instrument is to measure the elevation difference between two points. A circular level is used for rough judgment. When the circular level bubble is within the circular index circle, the circular level is in a vertical position. Because the circular level is perpendicular to the vertical axis of the leveling instrument, it ensures that the vertical axis is basically vertical. However, in actual operation, the instrument's coarse leveling process is significantly inadequate. Operators need to adjust the leveling by sequentially turning the base screws according to the position of the circular level bubble, ensuring that the circular level bubble is within the circular index circle. This process is complex, time-consuming, and labor-intensive. Furthermore, re-leveling is required after each movement of the device. Existing engineering surveying devices cannot automatically level, severely affecting surveying efficiency and causing large errors when measuring elevation differences. For example, in topographic surveying, if the leveling instrument is not coarsely leveled, the measured topographic relief data will deviate significantly from the actual data, affecting subsequent engineering planning and design work. Summary of the Invention

[0021] The linkage component includes a pushing component 4, which includes a rack 42 slidably connected to one side of the housing 2. One end of the rack 42 extends to the outside of the housing 2. A push plate 41 is provided on one side of the rack 42. A drive rod 44 is also rotatably connected inside the housing 2. A gear 43 is provided on the outside of the drive rod 44. The gear 43 meshes with the rack 42 to improve the leveling efficiency.

[0022] The linkage assembly also includes a drive component 5, which includes a turntable 51 located outside the drive rod 44. The surface of the turntable 51 is provided with a groove 52, which is arc-shaped. A round block 53 is slidably connected inside the groove 52. A sliding plate 54 is provided on one side of the round block 53. A base plate 55 is provided inside the outer shell 2.

[0024] The fixed structure 9 includes a slot 91 on the surface of the leveling plate 10. A spring 92 is installed inside the slot 91. A driven plate 93 is installed at the top of the spring 92. A rotating rod 95 is rotatably connected inside the slot 91. A rotating plate 94 is installed on the outside of the rotating rod 95. The rotating plate 94 is inclined. A spring is installed at one end of the rotating rod 95. A slot 96 is opened on the surface of the level instrument 3. The installation force of the level instrument 3 is converted into the limiting and storage force of the internal structure, laying a reliable foundation for subsequent leveling and mapping.

[0025] Working principle: The user fixes the level instrument 3 to the tripod 1. The operator secures the bottom of the level instrument 3 to the adjusting plate 10. The bottom of the level instrument 3 presses against the driven plate 93, causing the driven plate 93 to move towards the groove 91. The spring 92 at the bottom of the driven plate 93 is compressed and stores energy. The rotating plate 94 is initially tilted, and it does not obstruct the top of the driven plate 93. The bottom of the driven plate 93 presses against one end of the tilted rotating plate 94, causing the rotating plate 94 to drive the rotating rod 95 to rotate. The other end of the rotating plate 94 engages with the slot 96 on the surface of the level instrument 3. One end of the rotating rod 95 is equipped with a spring. For reset, the rotating rod 95 is rotatably connected to the slot 91, realizing a quick and stable connection and fixation between the level instrument 3, the adjusting plate 10, and the tripod 1. Through the cooperation of spring 2 92, rotating plate 94, and rotating rod 95, the initial limiting and energy storage reset functions are automatically completed, improving installation efficiency and connection stability, and reducing the risk of surveying affected by loose connection. With the help of spring 2 92 compression, rotating plate 94 tilt transmission, and spring reset, the installation force of the level instrument 3 is effectively converted into the limiting and energy storage of the internal structure, laying a reliable foundation for subsequent leveling and surveying. Compared with the traditional simple bolt fixation, it has significantly improved the ease of installation and stability. Inside the outer casing 2, a rectangular plate 61 is provided. Four sets of top posts 62 are evenly spaced at the top of the rectangular plate 61. The tops of the top posts 62 are movably connected to the adjusting plate 10. A connecting seat 71 is also provided on the outside of the rectangular plate 61. A horizontal plate 72 is rotatably connected to one side of the connecting seat 71. A rotating shaft 73 is provided at one end of the horizontal plate 72. An inclined vertical plate 74 is rotatably connected to the outside of the rotating shaft 73. A ball joint 75 is provided at the top of the vertical plate 74. The ball joint 75 is movably connected to the adjusting plate 10. Four sets of horizontal plates 72 and vertical plates 74 are evenly spaced, and these four sets of horizontal plates 72 and vertical plates 74 are used for simultaneous leveling of the level. Through the arrangement and coordination of four sets of top columns 62, horizontal plates 72, vertical plates 74 and ball joints 75, forces can be applied to the leveling plate 10 simultaneously from multiple directions, realizing multi-directional synchronous leveling of the level, greatly shortening the leveling operation time, reducing the difficulty and error of manual adjustment in each direction, improving leveling efficiency, and allowing the level to enter a stable and usable state more quickly. Through the rotation of the horizontal plate 72 around the connecting seat 71, the rotation of the vertical plate 74 around the rotating shaft 73, and the flexible adaptation of the ball joints 75, the leveling power is distributed to multiple directions, breaking through the limitations of traditional single-direction leveling, realizing efficient multi-directional synchronous leveling, and the leveling efficiency is superior to existing technologies.

[0026] Since the leveling plate 10 is connected to the top column 62, the operator needs to level the level by pushing the push plate 41 on the outside of the outer shell 2. The push plate 41 drives the rack 42 to slide and connect with the outer shell 2. The rack 42 moves and meshes with the gear 43. The gear 43 drives the drive rod 44 to rotate, which in turn drives the turntable 51 to rotate. The turntable 51 drives the four sets of grooves 52 on its surface to rotate. The four sets of grooves 52 have circular blocks 53 slidably connected inside. The circular blocks 53 drive the bottom sliding plate 54 to slide linearly and connect with the bottom plate 55. The bottom plate 55 is connected to the inner wall of the outer shell 2. The four sets of sliding plates 54 drive the support plate 81 on one side to move outward. The connecting plate 81 drives the rack 82 to move, the rack 82 meshes with the gear 83, the gear 83 drives the screw 84 to rotate, the screw 84 is threadedly connected to the sleeve 85, the outer shell 2 is provided with a long rod 86, the sleeve 85 is slidably connected to the long rod 86, the sleeve 85 drives the connecting block 88 connected to the top spring 87 to move and adjust, the connecting block 88 is connected to the vertical plate 74, transforming the simple pushing force applied manually into the movement and adjustment of multiple sets of vertical plates 74, which is easy to operate and can achieve leveling, reducing the operating threshold for workers, and at the same time, the spring 87 can provide a certain buffer and reset assistance after leveling, ensuring the stability of the structure after leveling.

[0027] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
