Description

Technical Field

[0001] This invention relates to the field of surveying equipment technology, and more specifically, to a high-precision surveying equipment for urban and rural planning. Background Technology

[0002] In the field of road engineering construction, surveying is the foundation for ensuring the quality of engineering planning, design, and construction. Its core lies in accurately obtaining the spatial geometric parameters of the road. Traditional surveying methods often rely on separate instruments such as levels and theodolites, which are inefficient. As a high-tech surveying instrument integrating optics, mechanics, and electronics, the total station can simultaneously and efficiently acquire multi-dimensional data such as horizontal angles, vertical angles, distances, and elevation differences by integrating electronic angle measurement, photoelectric distance measurement, and microprocessor systems, thus improving the accuracy and efficiency of surveying. In road surveying, the total station needs to be set up based on known control points. The coordinates of the station are determined by resection or polar coordinate method. Then, dense point cloud data is collected for the road centerline, edge lines, slopes, cross sections, and longitudinal sections. The coordinates and elevations are calculated and recorded in real time. Its application is not limited to topographic mapping and centerline setting out, but also extends to road slope, curvature, earthwork volume calculation, and construction quality monitoring.

[0003] When a total station is used in the field or in complex construction site environments, its stability is highly dependent on the reliability of the support system. Although traditional supports are easy to adjust, they have problems such as weak overall vibration resistance of the support legs, which can easily cause the instrument to tilt or sway, thus seriously affecting the accuracy of the measurement data. In particular, total stations are expensive, and when subjected to external impacts or natural forces such as strong winds, the risk of the support system tipping over is high, which may cause equipment damage and economic losses. To address this, we provide a high-precision surveying device for urban and rural planning. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this invention, the low-position design of the annular ring in the adjustment mechanism provides good stability to the device. By lowering the position of the annular ring, the center of gravity of the entire device is lowered, thereby enhancing the anti-overturning stability. This makes the device less prone to shaking or tilting under the action of external forces such as wind or slight collisions, ensuring the accuracy of measurement data and the safety of the instrument.

[0019] 2. In this invention, the auxiliary mechanism enables the device to remain stable under complex ground conditions, reducing measurement errors caused by minor displacement of the support. When the insertion rod is inserted into the ground, the triangular frame can effectively distribute the pressure and lateral force from the upper part of the instrument to a wider soil contact surface, such as the horizontal thrust generated by wind or accidental collision, thereby reducing the swaying of the support legs.

[0020] 3. In this invention, the counterweight on the omnidirectional ball is shifted by an adaptive mechanism. When the total station body turns to the right, the counterweight moves to the left through the linkage mechanism, thereby offsetting the shift of the center of gravity and keeping the overall center of gravity always in the center of the support surface, which significantly enhances the anti-overturning ability.

[0021] 4. In this invention, the annular ring is rotatably connected to the bottom of the connecting plate via a telescopic rod, and a spring is sleeved on the outside of the telescopic rod, so that a certain degree of deflection can occur in the horizontal direction, thereby ensuring the stability of the device.

Detailed Implementation

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0037] Example 1 further illustrates the high-precision surveying device for urban and rural planning proposed in this invention, which includes a total station body 100. A connecting plate 101 is detachably installed at the bottom of the total station body 100. A rotating frame 102 is circumferentially connected to the outer side of the connecting plate 101. A cylindrical support column 103 is symmetrically fixedly connected to one end of the rotating frame 102. A linkage block 104 is integrally formed between the two sets of support columns 103. A plug rod 105 is movably connected inside the linkage block 104. An adjustment mechanism 200 is provided at the bottom of the connecting plate 101. The adjustment mechanism 200 includes a driving component 201 provided at the bottom of the connecting plate 101 and a movable component 202 provided at the bottom of the connecting plate 101. The driving component 201 and the movable component 202 cooperate with each other. A fixing component 203 is provided on the outer side of the movable component 202.

[0038] The total station body 100 is securely connected to a three-pronged support column 103 via a rotating frame 102 at its bottom. The three-pronged support column 103 is evenly distributed, providing an extremely stable and adjustable level measurement reference for the precision body above. The pointed design at its bottom can effectively adapt to different ground conditions and prevent slippage, thereby ensuring the accuracy and reliability of high-precision field survey data.

[0039] The device is equipped with an adjustment mechanism 200 at the bottom of the connecting plate 101. By adjusting the position of the lowering ring 202d, the center of gravity of the entire device is lowered, thereby enhancing the anti-overturning stability. This makes the device less prone to shaking or tilting under the action of external forces such as wind or slight collisions, ensuring the accuracy of measurement data and the safety of the instrument. It can also help the device maintain stability on uneven ground. The device is also equipped with an auxiliary mechanism 300, which includes a locking member 301 at the bottom of the linkage block 104. A limiting member 302 is provided on the outside of the locking member 301. The insertion rod 105 cooperates with the limiting member 302 to position the device.

[0040] The insertion rod 105 and the limiting member 302 work together to form a solid triangular structure, which greatly enhances its ability to resist external forces in all directions. When the insertion rod 105 is inserted into the ground, the triangular frame can effectively distribute the pressure and lateral force from the top of the instrument to a wider soil contact surface, such as the horizontal thrust generated by wind or accidental collisions. This reduces the risk of the support legs swaying, twisting or sliding to one side, ensuring that it remains stable under complex ground conditions, reducing measurement errors caused by small displacements of the support, and ensuring the high accuracy of the survey data.

[0041] It also includes a push-back mechanism 400, which includes a support member 401 set in the linkage block 104, an abutment member 402 set at one end of the connecting rod 203d, and an offset member 403 set in the support member 401. The offset member 403 and the abutment member 402 cooperate to divide the stable structure of the device into two parts. If the survey is usually carried out in a relatively flat but slightly soft or uneven field with general accuracy requirements, the low position design of the annular ring 202d in the adjustment mechanism 200 can provide good stability and high efficiency. If the soil is loose or the stability requirements are high, the auxiliary mechanism 300 can make the device maintain stability under complex ground conditions. It also includes an adaptive mechanism 500, which includes a positioning member 501 set on the outside of the telescopic sleeve 201c, and an adaptive member 502 set at the bottom of the positioning member 501. The positioning member 501 and the adaptive member 502 cooperate to adjust the attitude of the device, so that the overall center of gravity is always kept in the center of the support surface, which significantly enhances the anti-overturning ability.

[0042] Working Principle: When in use, the total station body 100 is placed on the ground. In relatively flat but potentially slightly soft or uneven field surveys requiring general accuracy, the low-position design of the annular ring 202d in the adjustment mechanism 200 provides good stability to the device. By lowering the position of the annular ring 202d, the center of gravity of the entire device is lowered, thereby enhancing its anti-overturning stability. This makes the device less prone to shaking or tilting under the influence of external forces such as wind or minor collisions, ensuring the accuracy of measurement data and the safety of the instrument. In areas with loose soil, the auxiliary mechanism 300 helps the device remain stable under complex geological conditions, reducing measurement errors caused by minor displacement of the support. When the insertion rod 105 is inserted into the ground, the triangular frame effectively distributes the pressure and lateral forces from the top of the instrument to a wider soil contact surface, such as the horizontal thrust generated by wind or accidental collisions, thereby reducing the swaying of the support legs and ensuring high accuracy of the survey data.

[0043] Example 2

[0044] Based on Embodiment 1, the following technical features are added: The adjustment mechanism 200 includes a driving member 201 disposed at the bottom end of the connecting plate 101, and a movable member 202 disposed at the bottom end of the connecting plate 101. The device obtained by the adjustment mechanism 200 is less likely to shake or tilt under the action of external forces such as wind or slight collisions, thus ensuring the accuracy of measurement data and the safety of the instrument. A fixing member 203 is disposed on the outside of the movable member 202. The driving member 201 includes a cylinder push rod 201a detachably installed at the bottom end of the connecting plate 101. A stop block 201b is fixedly connected to the output end of the cylinder push rod 201a. A telescopic sleeve 201c is fixedly connected to the bottom end of the connecting plate 101. The stop block 201b is fixedly connected to the inner wall of the telescopic sleeve 201c.

[0045] Depend on Figures 1 to 11 It can be seen that the cylinder push rod 201a is adjusted by an external controller. The cylinder push rod 201a drives the stop block 201b to move vertically. The stop block 201b drives the extended part of the telescopic sleeve 201c to move downward. The telescopic sleeve 201c drives the ring 202d to move downward. By adjusting and lowering the position of the ring 202d, the center of gravity of the entire device is lowered, thereby enhancing the anti-overturning stability.

[0046] The movable component 202 includes a first bearing seat 202a fixedly connected to the bottom end of the connecting plate 101 in a circular shape. A telescopic rod 202b is rotatably connected inside the first bearing seat 202a. A second bearing seat 202c is rotatably connected to the bottom end of the telescopic rod 202b. An annular ring 202d is fixedly connected to the bottom end of multiple sets of second bearing seats 202c. A tension spring 202e is sleeved on the outer wall of the telescopic rod 202b. The tension spring 202e is a carbon spring with high strength and is convenient for daily use. The fixed component 203 includes a fixed plate 203a outside the annular ring 202d in a circular shape. A corresponding sliding hole 203b is provided inside the fixed plate 203a. A connecting plate 203c is slidably connected inside the sliding hole 203b. A connecting rod 203d is fixedly connected to the bottom end of the connecting plate 203c. A through groove 203e is provided inside the linkage block 104. The connecting rod 203d is correspondingly located in the through groove 203e.

[0047] Depend on Figures 1 to 11 It can be seen that the bottom end of the connecting plate 101 is circumferentially fixedly connected to three sets of bearing seats 202a. A telescopic rod 202b is rotatably connected inside the bearing seat 202a. A tension spring 202e is sleeved on the outside of the telescopic rod 202b. An annular ring 202d is installed at the bottom end of the telescopic rod 202b through the bearing seat 202c. Through the above structure, the annular ring 202d can move vertically and deflect to a certain extent in the horizontal direction during use, thereby ensuring the stability of the device. A long strip-shaped fixing plate 203a is fixedly connected to the outside of the annular ring 202d. A long strip-shaped sliding hole 203b is provided inside the fixing plate 203a. The rotating shaft inside the connecting plate 203c can be slidably connected in the sliding hole 203b.

[0048] Working principle: In use, the total station body 100 is placed on the ground. If a survey with general accuracy requirements is to be conducted in a relatively flat but possibly slightly soft or uneven field, the external controller activates the cylinder push rod 201a. The cylinder push rod 201a drives the stop block 201b to move vertically. The stop block 201b drives the extended part of the telescopic sleeve 201c to move downward. The telescopic sleeve 201c drives the annular ring 202d to move downward. By lowering the position of the annular ring 202d, the center of gravity of the entire device is lowered, thereby enhancing the anti-overturning stability. The annular ring 202d is rotatably connected to the bottom end of the connecting plate 101 through the telescopic rod 202b, and a spring is sleeved on the outside of the telescopic rod 202b. This allows for a certain degree of deflection in the horizontal direction, thereby ensuring the stability of the device.

[0049] Example 3

[0050] Based on Embodiment 2, the following technical features are added: It also includes an auxiliary mechanism 300 disposed within the linkage block 104. The auxiliary mechanism 300 includes a locking member 301 disposed at the bottom end of the linkage block 104. A limiting member 302 is disposed on the outside of the locking member 301. The locking member 301 includes a locking cylinder 301a fixedly connected to the bottom end of the linkage block 104. A cavity 301b is formed inside the locking cylinder 301a. The insertion rod 105 passes through the cavity 301b. A locking ring 301c is disposed at the position of the insertion rod 105 in the cavity 301b. A connecting rod 301d is rotatably connected to the outside of the locking ring 301c. Slide openings 301e are provided on both sides of the cavity 301b. Slide grooves 301f are provided inside the slide openings 301e on both sides.

[0051] Its auxiliary mechanism 300, through the cooperation of the insertion rod 105 and the limiting member 302, disperses the pressure and lateral force from the upper part of the instrument to a wider soil contact surface, such as the horizontal thrust generated by wind or accidental collisions. This reduces the risk of the outriggers swaying, twisting, or slipping to one side, ensuring its stability even under complex geological conditions. Figures 1 to 11 It can be seen that its locking cylinder 301a has a cylindrical structure and a cylindrical cavity 301b is formed inside. The insertion rod 105 can move in the cavity 301b. The cavity 301b has long strip-shaped sliding openings 301e on both sides. The sliding openings 301e on both sides form a U-shaped sliding groove 301f. The insertion rod 105 is rotatably connected to the outer wall of the insertion rod 105.

[0052] The limiting component 302 includes a second connecting rod 302a symmetrically rotatably connected to the slide 301e, a third connecting rod 302b rotatably connected to the end of the second connecting rod 302a, a third connecting rod 302b slidably connected to the end of the third connecting rod 302b in the slide groove 301f, and a first connecting rod 301d rotatably connected to the third connecting rod 302b. As shown in the figure, the second connecting rod 302a and the third connecting rod 302b form a triangular structure with the movement of the insertion rod 105, which greatly enhances its ability to resist external forces in all directions. When the insertion rod 105 is inserted into the ground, the triangular frame can effectively disperse the pressure and lateral force from the top of the instrument to a wider soil contact surface. When the insertion rod 105 moves in the opposite direction, the first connecting rod 301d drives the third connecting rod 302b to retract into the slide 301e as the insertion rod 105 moves.

[0053] Working principle: In use, the cylinder push rod 201a is activated by the external controller. The cylinder push rod 201a drives the stop block 201b to move vertically. The stop block 201b drives the extended part of the telescopic sleeve 201c to move upward. The telescopic sleeve 201c drives the annular ring 202d to move upward. The annular ring 202d drives the connecting plate 203c on the fixed plate 203a to move synchronously. At the same time as the connecting plate 203c moves upward, the push mechanism 400 drives the insertion rod 105 to move downward. At this time, the insertion rod 105 drives the locking ring 301c to move synchronously. Its connecting rod 202a and connecting rod 302b form a triangular structure with the movement of the insertion rod 105, which greatly enhances its ability to resist external forces in all directions and ensures the high accuracy of the survey data.

[0054] Example 4

[0055] Based on Embodiment 3, the following technical features are added: It also includes a push mechanism 400 disposed in the linkage block 104. The push mechanism 400 includes a support member 401 disposed in the linkage block 104. One end of the connecting rod 203d is provided with an abutment member 402. The support member 401 is provided with an offset member 403. The offset member 403 and the abutment member 402 cooperate with each other. The support member 401 includes a support cylinder 401a fixedly connected in the through groove 203e. The support cylinder 401a has a movable groove 401b formed in it. The bottom end of the support cylinder 401a protrudes upward to form a protrusion 401c. One end of the insertion rod 105 is movably connected in the protrusion 401c. A through hole 401d is formed in the middle of the protrusion 401c.

[0056] Depend on Figures 1 to 11 It can be seen that the device drives the insertion rod 105 to move in the opposite direction through the push mechanism 400, so that the outer side of the insertion rod 105 forms a triangular structure, which makes the device stable under complex ground conditions. Its support cylinder 401a is a cylindrical structure, and its insertion rod 105 slides inside the support cylinder 401a.

[0057] The abutting member 402 includes an abutting groove 402a at the end of the connecting rod 203d. A compression spring 402b is fixedly connected to the inner cavity of the abutting groove 402a. One end of the compression spring 402b is fixedly connected to the top of the insertion rod 105. Abutting part 1 402c and abutting part 2 402d are integrally formed on both sides of the inner side of the abutting groove 402a. The offsetting member 403 includes an inclined hole 403a on the outer wall of the insertion rod 105. An inclined rod 403b is movably connected in the inclined hole 403a. An offsetting part 1 403c and an offsetting part 2 403d are integrally formed at both ends of the inclined rod 403b. Abutting part 1 402c and offsetting part 1 403c cooperate with each other. Offset part 2 403d cooperates with abutting part 2 402d. Offset part 1 403c and offsetting part 2 403d abut against the inner wall of the through hole 401d.

[0058] Depend on Figures 1 to 11 It can be seen that the bottom end of the connecting rod 203d is provided with a cylindrical abutment groove 402a. One end of the connecting rod 203d is slidably connected in the movable groove 401b. The insertion rod 105 is connected to the inside of the abutment groove 402a through a compression spring 402b. The compression spring 402b is a carbon spring with high strength, which is convenient for daily use. The two ends of the inclined rod 403b are integrally formed with offset part one 403c and offset part two 403d, forming a U-shaped structure. Since offset part one 403c and offset part two 403d abut against the inner wall of the through hole 401d respectively, when the connecting rod 203d moves in the abutment groove 402a, the abutment part one 402c and offset part one 403c cooperate, and offset part two 403d cooperates with the abutment part two 402d. At this time, the connecting rod 203d moves down and the insertion rod 105 moves up. When the connecting rod 203d moves up, the insertion rod 105 moves down.

[0059] Working Principle: For general-precision surveys in relatively flat but potentially slightly soft or uneven terrain, the low-position design of the annular ring 202d in the adjustment mechanism 200 provides good stability. In loose soil or scenarios requiring higher stability, the upward movement of the annular ring 202d creates a triangular structure on the outer side of the insertion rod 105. In practical use, the external controller activates the cylinder push rod 201a, which moves the stop block 201b vertically. The stop block 201b then moves the extended portion of the telescopic sleeve 201c upward, which in turn moves the annular ring 202d upward. The annular ring 202d then moves the connecting plate 203c on the fixed plate 203a synchronously, which in turn moves the connecting rod 203d synchronously. During movement, since the offset part 1 403c and the offset part 2 403d are respectively abutted against the inner wall of the through hole 401d, when the connecting rod 203d moves in the contact groove 402a, the contact part 1 402c and the offset part 1 403c cooperate, and the offset part 2 403d cooperates with the contact part 2 402d. At this time, the connecting rod 203d moves down and the insertion rod 105 moves up. When the connecting rod 203d moves up, the insertion rod 105 moves down. When the insertion rod 105 is inserted into the ground, a triangular structure is formed on the outside of the insertion rod 105. The triangular frame can effectively disperse the pressure and lateral force from the top of the instrument to a wider soil contact surface, ensuring that it can remain stable under complex ground conditions, reducing measurement errors caused by small displacements of the support, and ensuring high accuracy of the survey data.

[0060] Example 4

[0061] Based on Embodiment 3, the following technical features are added: the positioning component 501 includes a positioning block 501a that is circumferentially fixedly connected to the outside of the telescopic sleeve 201c. The positioning block 501a is fixedly positioned at the end of the telescopic sleeve 201c. Multiple sets of positioning blocks 501a are fixedly connected to the outer wall of an arc plate 501b. Multiple sets of arc plates 501b are fixedly connected to the upper end face of an annular plate 501c. A support plate 501d is fixedly connected to the lower end face of the total station body 100. A gear ring 501e is rotatably connected to the inner wall of the annular plate 501c through a bearing. The support plate 501d is fixedly connected to the circumference of the gear ring 501e. A motor 501f is detachably installed on the inner wall of the arc plate 501b. The motor 501f is adjusted by an external controller. A gear 501g is fixedly connected to the rotor shaft end of the motor 501f. The gear 501g meshes with the gear ring 501e.

[0062] Depend on Figures 1 to 11It can be seen that the outer side of the telescopic sleeve 201c is fixed with an arc plate 501b by three sets of positioning blocks 501a. An annular plate 501c is fixed on the upper end face of the arc plate 501b. The annular plate 501c is rotatably connected to a gear ring 501e through a bearing. Since the motor 501f drives the gear 501g to rotate and the gear 501g meshes with the gear ring 501e, the support plate 501d on the upper end face of the gear ring 501e rotates synchronously. Since the support plate 501d is fixedly connected to the lower end face of the total station body 100, the angle of the total station body 100 is adjusted.

[0063] The adaptive component 502 includes a straight rod 502a fixedly connected to the support plate 501d. A support rod 502b is fixedly connected to the bottom end of the straight rod 502a. An annular bar 502c is rotatably connected to the bottom end of the support rod 502b via a bearing. An arc-shaped part 502d is fixedly connected to the inner wall of the annular bar 502c. A sliding groove 502e is provided at the bottom end of the connecting plate 101. The sliding groove 502e is T-shaped. A universal ball 502f is connected to the sliding groove 502e via a spring. The universal ball 502f moves left and right within the sliding groove 502e. A counterweight block 502h is fixedly connected to the bottom end of the universal ball 502f. The arc-shaped part 502d abuts against the universal ball 502f.

[0064] Depend on Figures 4 to 11 It can be seen that a straight rod 502a is fixedly connected inside the support plate 501d, and a support rod 502b is fixedly connected to the bottom end of the straight rod 502a. The support rod 502b is located on the outside of the bottom end of the straight rod 502a, and is not located at the center of the bottom end of the straight rod 502a. Furthermore, the connecting plate 101 has an arc-shaped groove structure, such as... Figure 4 As can be seen from the figure, the rotation path of the support rod 502b is set in the groove, and the bottom end of the support rod 502b is fixedly connected to the ring bar 502c. When the ring bar 502c rotates, it drives the arc part 502d to operate synchronously. At this time, when the angle of the total station body 100 deflects, the counterweight block 502h at the bottom of the universal ball 502f is exactly opposite to it, thus offsetting the center of gravity shift.

[0065] Working principle: When the angle of the total station body 100 needs to be adjusted, simply start the motor 501f through the external controller. The motor 501f drives the gear 501g to rotate. Since the gear 501g meshes with the gear ring 501e, it drives the support plate 501d on the upper end of the gear ring 501e to move synchronously. At the same time, the rotation of the support plate 501d drives the support rod 502b at the bottom of the straight rod 502a to operate synchronously. At this time, the support rod 502b drives the arc-shaped part 502d on the inner side of the ring bar 502c to rotate synchronously. Since the arc-shaped part 502d abuts against the universal ball 502f, it causes the counterweight 502h on the universal ball 502f to shift. When the total station body 100 turns to the right, the counterweight 502h moves to the left through this linkage mechanism, thereby offsetting the shift of the center of gravity and keeping the overall center of gravity always in the center of the support surface, significantly enhancing the anti-overturning ability.
