Description

Technical Field

[0001] This utility model relates to the field of surveying benchmark technology, and in particular to an adjustable multi-purpose surveying benchmark for urban planning. Background Technology

[0002] The surveying benchmark used in urban planning surveying is an upright rod-shaped tool with alternating red and white or black and white scale markings. It is usually made of lightweight aluminum alloy or fiberglass and serves as a visual reference for ground surveying. With the help of instruments such as theodolites and total stations, the benchmark helps surveyors quickly locate target points and determine horizontal distance, elevation, or angle data through its vivid color contrast and precise scale. Especially in scenarios such as topographic mapping, road layout, and building boundary marking, the benchmark can significantly improve the efficiency and accuracy of field surveying and is one of the key tools for collecting basic data for urban planning.

[0003] Commercially available surveying benchmarks suffer from drawbacks such as inflexible adjustment and structural instability. This leads to swaying or tilting, especially during dynamic measurements, potentially causing deviations of several centimeters. It can also result in benchmark collapse, structural imbalance, increased stress risks, and even total collapse. Furthermore, inflexible adjustment increases on-site adjustment time, requiring repeated adjustments and calibrations. This can lead to subsequent construction based on incorrect data, requiring rework and potentially causing even greater losses.

[0004] Therefore, to address the problems of traditional surveying benchmarks being inflexible and structurally unstable, leading to decreased measurement accuracy, increased safety hazards, reduced work efficiency, and increased equipment wear and tear and costs, an adjustable multi-purpose urban planning surveying benchmark can be designed to solve these problems.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-5This utility model provides an embodiment: an adjustable multi-purpose urban planning surveying and mapping pole, including a pole 1; a mounting disk 2 is fixedly connected to the pole 1, and a driving assembly is fixedly connected to the mounting disk 2. The output end of the driving assembly is driven by a lead screw 4 and a threaded rod 6, and the driving assembly is used to drive the lead screw 4 and the threaded rod 6 to rotate. The lead screw 4 and the threaded rod 6 are rotatably connected to the mounting disk 2. A support assembly is connected to the lead screw 4. A first telescopic sleeve 7 is threadedly connected to the threaded rod 6, and a threaded sleeve 8 is threadedly connected to the threaded rod 6. The first telescopic sleeve 7 and the threaded sleeve 8 are rotatably connected. A second telescopic sleeve 9 is threadedly connected to the threaded sleeve 8. The second telescopic sleeve 9 and the first telescopic sleeve 8 are rotatably connected. A telescopic sleeve 7 is slidably connected, and a fixed sleeve 10 is slidably connected to the outside of the first telescopic sleeve 7. The fixed sleeve 10 is fixedly connected to the mounting disc 2. When measuring, the upright 1 is fixed at the designated measurement position, and then the drive assembly outputs power to the lead screw 4 and the threaded rod 6, causing the lead screw 4 and the threaded rod 6 to rotate. The lead screw 4 drives the support assembly to move until the support assembly opens and firmly fixes the upright 1. The threaded rod 6 causes the first telescopic sleeve 7, which is threadedly connected to the outside, to move linearly, and the threaded sleeve 8 rotates while moving linearly, driving the second telescopic sleeve 9, which is threadedly connected to the outside, to move linearly, thus completing the extension of the rod and realizing the height change.

[0019] Please see Figures 2-5In this embodiment, the driving assembly includes a first motor 301, a driving gear 302, and a driven gear 303. The first motor 301 is fixedly connected to the mounting disk 2, and its output end is fixedly connected to the driving gear 302. The first motor 301 drives the driving gear 302 to rotate. The driving gear 302 is fixedly connected to the lead screw 4, and one side of the driving gear 302 meshes with the driven gear 303. The driven gear 303 is fixedly connected to the threaded rod 6. The first motor 301 outputs torque to the driving gear 302, causing the driving gear 302 to drive the lead screw 4 to rotate, and simultaneously drive the driven gear 303 meshing on one side to rotate. The driven gear 303 then drives the threaded rod 6 to rotate. The support assembly includes an upper ring 501, a lower ring 502, a first support rod 503, a second support rod 504, and a support leg 505. The upper ring 501 and the lower ring 502 are threadedly connected to the lead screw 4, and several first support rods 503 are rotatably connected to the upper ring. On 501, the other end of the first support rod 503 is rotatably connected to the second support rod 504. A support leg 505 is rotatably connected to the second support rod 504. The other end of the second support rod 504 is rotatably connected to the lower ring 502. When the lead screw 4 rotates, it drives the upper ring 501 and the lower ring 502, which are threaded on it, to move linearly. This causes the first support rod 503 and the second support rod 504 to rotate on the upper ring 501 and the lower ring 502, respectively, so that the support leg 505 contacts the ground and the upright rod 1 is structurally stable. A fixed platform 11 is fixedly connected above the second telescopic sleeve 9. A rotating assembly is fixedly connected to the fixed platform 11. A connecting frame 13 is fixedly connected to the output end of the rotating assembly. The rotating assembly is used to drive the connecting frame 13 to rotate. The connecting frame 13 is rotatably connected to the fixed platform 11. The rotating assembly outputs power to the connecting frame 13, causing the connecting frame 13 to rotate on the fixed platform 11, thereby realizing the angle change of the measuring device.

[0020] Please see Figures 1-5In this embodiment, the rotating assembly includes a second motor 1201 and a drive shaft 1202. The second motor 1201 is fixedly connected to the fixed platform 11, and the output end of the second motor 1201 is fixedly connected to the drive shaft 1202. The second motor 1201 is used to drive the drive shaft 1202 to rotate. The drive shaft 1202 is fixedly connected to the connecting frame 13. The second motor 1201 outputs torque to the drive shaft 1202, causing the drive shaft 1202 to rotate, thereby driving the connecting frame 13 to rotate. A rotating platform 14 is rotatably connected to the connecting frame 13, below the upright 1. A conical head 15 is fixedly connected. The measuring tool is installed on the rotating platform 14. The rotating platform 14 is driven to rotate by the connecting frame 13 to achieve multi-angle measurement. The conical head 15 is firmly inserted into the ground to fix the center of the upright 1. The upright 1 is provided with a sliding groove 101. The lead screw 4 is rotatably connected to the sliding groove 101. The upper ring 501 and the lower ring 502 are slidably connected to the sliding groove 101. When the lead screw 4 rotates on the sliding groove 101, the upper ring 501 and the lower ring 502 slide on the sliding groove 101, limiting the movement of the upper ring 501 and the lower ring 502.

[0021] During measurement, the measuring tool is mounted on the rotating platform 14, and the conical head 15 is firmly inserted into the ground. The upright rod 1 is fixed at the designated measurement position. Then, the first motor 301 outputs torque to the driving gear 302, causing the driving gear 302 to drive the lead screw 4 to rotate. At the same time, the driven gear 303 meshing on one side rotates, and the driven gear 303 drives the threaded rod 6 to rotate. The lead screw 4 drives the upper ring 501 and lower ring 502 threadedly connected to it to move linearly on the slide groove 101, so that the first support rod 503 and the second support rod 504 respectively rotate on the upper ring 501 and lower ring 502. The support leg 505 is rotated to make contact with the ground, and the upright 1 is installed in a stable manner. The threaded rod 6 causes the first telescopic sleeve 7, which is threaded to the outside, to move linearly. The threaded sleeve 8 rotates while moving linearly, which drives the second telescopic sleeve 9, which is threaded to the outside, to move linearly, thus completing the extension of the rod and realizing the height change. Then, the second motor 1201 outputs torque to the drive shaft 1202, which rotates the drive shaft 1202, thereby driving the connecting frame 13 to rotate. The connecting frame 13 drives the rotating platform 14 to rotate, realizing multi-angle measurement.

[0022] Through the above steps, the structural stability of the surveying benchmark is achieved using support components, reducing benchmark swaying or tilting, ensuring data accuracy, reducing the risk of tipping over, and ensuring personnel safety. The drive components, rotating components, and multiple transmission parts enable flexible adjustment of the measuring device's height and angle, allowing for rapid adaptation to different measurement needs and avoiding errors caused by equipment limitations. It also allows for quick height and angle adjustments, shortening on-site operation time. This solves the problems of traditional surveying benchmarks being inflexible and structurally unstable, leading to decreased measurement accuracy, increased safety hazards, reduced work efficiency, and increased equipment wear and tear and costs.
