Description

Technical Field

[0001] The present invention relates to the technical field of surveying instrument positioning, and in particular to a surveying instrument positioning device for surveying and mapping engineering. Background Art

[0002] Surveying instruments are a general term for a series of professional instruments that are used to measure and draw maps, topographic maps, engineering drawings, etc. These instruments include theodolites, levels, total stations, gyrotheodolites, phototheodolites, and stereo coordinate measuring instruments.

[0003] After searching the Chinese patent publication number: CN118274231B, a surveying instrument positioning device for engineering surveying is disclosed, including a circular support seat, the top surface of the circular support seat is rotatably clamped with a support plate, one end of the support plate is rotatably connected to a screw rod, the outer side of the screw rod is screwed and connected to a movable plate, the top surface of the movable plate is fixed with a surveying instrument body, and the bottom surface of the circular support seat is annularly rotatably connected with a plurality of support legs 1 at equal angles; in the present invention, the surveying instrument body can be initially fixed to the ground by a plurality of support legs 2, and the circular support seat outside the rotating spherical shell body can be placed horizontally without being affected by the complex ground.

[0004] Since existing real estate surveying and mapping devices are difficult to quickly fine-tune after being fixed, workers often need to repeatedly drive the entire device to make adjustments. Since traditional surveying and mapping devices are often bulky as a whole, repeated adjustments greatly increase labor intensity.

[0005] After searching the Chinese patent publication number: CN118129034B, an azimuth positioning surveying and mapping device belongs to the field of azimuth positioning surveying and mapping technology. The azimuth positioning surveying and mapping device includes a surveying instrument and a support extension and retraction assembly. A base is installed at the bottom of the surveying instrument, a support seat is installed at the bottom of the base, a connecting column is connected to the internal thread of the support seat, a connecting ring is installed inside the base, and the connecting column is threadedly connected to the base through the connecting ring. A support frame is installed on the outside of the support seat, and a support leg is movably connected to the inside of the support frame. The fixed frame is fixedly connected to the bottom of the support seat. By setting the support extension and retraction assembly, the user can support and stabilize the surveying instrument, and the extension and retraction and length adjustment of the support frame and the support leg are synchronized, thereby improving the convenience and operation efficiency of the horizontal support of the surveying instrument.

[0006] However, after the device is inserted into the soil and positioned, slight errors may occur during the positioning and installation of the surveying instrument, so adjustments are still required after installation. However, in poor geological environments, the operation will be extremely troublesome and adjustments cannot be made quickly and effectively.

[0007] After searching the Chinese patent publication number: CN113803588B, a surveying instrument positioning device for surveying and mapping engineering includes a carrying box, a rotating mechanism is provided on one side of the carrying box, a driving rod is provided on the rotating mechanism, and the driving rod is rotatably connected in the carrying box. The present invention can rotate the overall gravity of the carrying box to the supporting column, so that the surveying instrument can be moved in a small range without moving the tripod during the surveying process, making the surveying instrument more convenient during the surveying process, and at the same time, it can increase the stability and safety of the surveying instrument, and can automatically position the surveying instrument after it moves, making the surveying instrument more stable during the surveying process. At the same time, when the surveying instrument needs to change the surveying direction, the surveying instrument itself is automatically rotated and adjusted, effectively increasing the convenience and practicality of the surveying instrument.

[0008] However, in real estate surveying, the surveying instrument needs to remain level at all times to ensure the accuracy of the measurement results. However, due to the unevenness of the on-site ground or other external environmental factors, the surveying instrument often needs to be manually leveled after changing the measurement position. This process makes the work time-consuming and inefficient.

The design of the hollow bevel gear 35 includes high-strength materials and a precise gear ratio with the driven bevel gear 24 to ensure the efficiency and reliability of power transmission. The limit slide 36 is used to limit and guide the movement of the bearing column 37 to ensure the stability and accuracy of the bearing column 37 during movement. The design of the limit slide 36 includes a sliding bearing to reduce friction and improve the smoothness of movement. The function of the bearing column 37 is to support and fix the cross connecting rod 2 38 and to carry the rotation of the cross connecting rod 2 38. The cross connecting rod 2 38 is a component connecting the bearing column 37 and the micro motor 39, which provides a stable carrier installation position. The specific model of the micro motor 39 is m300, which is the power source of the power assembly 3. The driving end of the micro motor 39 passes through the cross connecting rod 2 38 and is fixedly connected to the screw rod 34.

The design of the top column 1 44 and the top column 2 45 adopts one long and one short, which are used for support and adjustment. like Figure 2 - Figure 8 As shown, the top of the support rod assembly 4 is fixedly connected with an adjustment assembly 5, and the adjustment assembly 5 includes a connecting member 51, and two connecting members 51 are provided, wherein the bottom end of one connecting member 51 is fixedly connected to the top column 1 44, and the bottom end of the other connecting member 51 is fixedly connected to the top column 2 45, and a seesaw 52 is movably connected to the outer side of the connecting member 51, and a positioning seat 53 is rotatably connected to the outer end of the seesaw 52 away from the connecting member 51, and the top of the seesaw 52 is rotatably connected to a push rod 54, and a limiting groove 55 is provided inside the push rod 54, and the top ends of the two push rods 54 are rotatably connected to an adjustment plate 56, and the bottom end of the positioning seat 53 is fixedly connected to the connecting disk 26, and the bottom end of the mounting seat 71 is fixedly connected to the adjustment plate 56; Two connecting members 51 are provided, which are respectively fixed at the bottom ends of the top column 1 44 and the top column 2 45. Their main function is to connect the top column with the adjustment component 5, transmit force and adjust the position. This design enables the adjustment component 5 to transmit force between the top columns to achieve fine adjustment of the position of the surveying instrument. The seesaw 52 is used as a lever to adjust the position of the top rod 54 by rotation, thereby fine-tuning the angle of the surveying instrument. The design of the seesaw 52 enables it to rotate around a fixed point, and uses the lever principle to amplify the operating force, so that even a small rotation can cause a significant movement of the top rod 54, thereby achieving precise adjustment of the angle of the surveying instrument. The positioning seat 53 is used to fix and support The seesaw 52 ensures the stability of the seesaw 52 during the adjustment process. The push rod 54 is connected to the adjustment plate 56 through the limit groove 55 to achieve precise control of the position of the adjustment plate 56. The push rod 54 is connected by bolts to ensure close combination with the limit groove 55, providing stable up and down movement capability. The design of the limit groove 55 provides a moving space that can slide up and down, so that the push rod 54 can move freely within a certain range. This design not only provides the necessary adjustment range, but also limits excessive movement, ensuring the precise positioning of the adjustment plate 56. The adjustment plate 56 serves as a connection platform to transmit the adjustment of the push rod 54 to the mounting seat 71, so as to achieve fine adjustment of the position and angle of the surveying instrument. like Figure 2 , Figure 3 and Fig. 9 As shown, the inside of the adjustment component 5 is slidably connected with a balancing component 6, and the balancing component 6 includes a slider 61, the outer side of the slider 61 is slidably connected to the top rod 54 through a limiting groove 55, one end of the slider 61 is fixedly connected to a buffer damper 62, and a spring 1 63 is sleeved on the outer side of the buffer damper 62, and the end of the buffer damper 62 away from the slider 61 is rotatably connected to the connecting shaft 64, one end of the spring 1 63 is fixedly connected to the slider 61, and the other end of the spring 1 63 is fixedly connected to the connecting shaft 64, and the end of the connecting shaft 64 away from the buffer damper 62 is rotatably connected to a coupling column 65, and the end of the coupling column 65 away from the connecting shaft 64 is rotatably connected to a multi-directional connecting block 66; The outer side of the slider 61 is slidably connected to the top rod 54 through the limit groove 55. This design allows the slider 61 to perform precise linear movement on the top rod 54. At the same time, the limit groove 55 limits the movement range of the slider 61 to ensure that it does not exceed the predetermined position during the adjustment process. The buffer damper 62 is fixedly connected to one end of the slider 61. Its main function is to provide buffering and damping effects when the slider 61 moves. This design helps to reduce excessive movement caused by adjustment or accidental impact and protect the surveying instrument from damage. The design of the spring 63 provides a restoring force to help the slider 61 return to its initial position after adjustment. In the initial position, the connecting shaft 64 is one of the fixed points of the spring 1 63, and the end thereof away from the buffer damper 62 is rotatably connected to the connecting column 65. The material selection of the connecting shaft 64 needs to ensure sufficient strength to ensure that the force can be stably transmitted under the action of the spring 1 63. The function of the connecting column 65 is to transmit the force of the spring 1 63 to the multi-directional connecting block 66, and at the same time, the multi-directional connecting block 66 can be adjusted in multiple directions. The multi-directional connecting block 66 is the end component of the balancing component 6, which is connected to the adjusting component 5 through the connecting column 65. The design of the multi-directional connecting block 66 allows it to rotate and connect in multiple directions; like Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown, the multi-directional connection block 66 is rotatably connected to an upper telescopic column 67, the top of the upper telescopic column 67 is fixedly connected to the adjustment plate 56, and one end of the multi-directional connection block 66 away from the upper telescopic column 67 is rotatably connected to a lower telescopic column 68, and a buffer column 69 is slidably connected to the outer side of the lower telescopic column 68. A second spring 610 is arranged inside the buffer column 69, one end of the second spring 610 is fixedly connected to the buffer column 69, and the other end of the second spring 610 is fixedly connected to the lower telescopic column 68; The design of the multi-directional connection block 66 allows the telescopic column to rotate and connect in different directions, which provides great flexibility and multi-directional connection capabilities, allowing the surveying instrument to be quickly adjusted to the required measuring position. The main function of the upper telescopic column 67 is to support the adjustment plate 56 and enable the adjustment plate 56 to move within a certain range to adapt to different measurement height requirements. This design allows the surveying instrument to be quickly adjusted to a suitable height according to the actual measurement environment, thereby improving the flexibility and efficiency of the measurement. The function of the lower telescopic column 68 is to work in conjunction with the upper telescopic column 67 to achieve the up and down adjustment function of the adjustment plate 56 and provide additional support. The buffer column 69 provides a buffering effect when the lower telescopic column 68 performs telescopic movement, reduces impact, and improves stability during the measurement process. The second spring 610 provides elastic force to help the telescopic column remain stable during the telescopic process and return to its original state after the external force is removed, so that the lower telescopic column 68 can quickly return to its initial position after adjustment to maintain accurate measurement.

[0037] Working principle: like Figure 1 - Fig. 9 As shown: When in use: when the turning handle 31 rotates, the hollow bevel gear 35 at the bottom is driven to rotate synchronously. Since the hollow bevel gear 35 is meshed with the driven bevel gear 24, the driven bevel gear 24 transmits the rotational force to the rotating disk 22 and the connecting column 25. At this time, the connection disk 26 at the top will synchronously drive the accommodating ring 28 to rotate due to the rotation of the connection column 25. Dear, the adjustment component 5, the balance component 6, and the surveying and mapping component 7 are all placed on the second rotating slide groove 27, so when the connection disk 26 rotates, they will rotate synchronously, thereby achieving the effect of adjusting the direction of the surveying and mapping instrument body 72; When the angle of the surveying instrument body 72 needs to be adjusted, the micro motor 39 is started, and the rotation of the micro motor 39 drives the screw rod 34 to rotate. At this time, under the action of the threaded column 41, the screw rod 34 is threadedly connected to the threaded column 41 and achieves the effect of moving up or down. The cross connecting rod 2 38 slides with the cross groove 43 on the threaded column 41, so the three screw rods 34 will realize a straight up and down motion trajectory when rotating, thereby achieving the effect of adjusting the top column 1 44 or the top column 2 45 up and down; When the movement of the top column 1 44 or the top column 2 45 drives the connecting member 51 to move upward or downward, the outer seesaw 52 of the connecting member 51 will be movably connected to the outer side of the connecting member 51. When the connecting member 51 moves downward, the positioning seat 53 will drive the top rod 54 to move upward. When the connecting member 51 moves upward, it will drive the top rod 54 to move downward. Therefore, the adjustment plate 56 can achieve the effect of left and right height adjustment through the movement of the top rod 54. During the process of adjusting the angle, the slider 61 will slide on the push rod 54. When the push rod 54 on one side moves toward the top, the outer side of the push rod 54 will contact the slider 61 and drive the slider 61 to move toward the top. At this time, the buffer damper 62 on the slider 61 will generate a pulling force and a compressing extrusion force. The spring 1 63 is kept balanced, and through the connection between the connecting shaft 64, the connecting column 65 and the multi-directional connecting block 66, the upper telescopic column 67 and the lower telescopic column 68 are driven to move up and down for fine-tuning effect, ensuring that the adjustment plate 56 remains in a stable environment during the angle adjustment process. Secondly, when the lower telescopic column 68 at the bottom telescopes and moves in the buffer column 69, the spring 2 610 in the buffer column 69 will generate an extrusion force due to compression, and exert a certain extrusion force during the angle adjustment process, ensuring that the stability of the entire device always maintains the effect of three points in one line. After the pressure applied to the connecting member 51 is cancelled, the elasticity released by the spring 2 610 is applied to the multi-directional connecting block 66, and when it is transmitted back to the buffer damper 62 and the spring 1 63 through the multi-directional connecting block 66, the buffer damper 62 acts as a buffer structure to provide an effect of preventing back and forth shaking, and the spring 1 63 acts as a release of tension and compression, so that the entire device quickly returns to the initial state and maintains a horizontal effect.
