Description

Technical Field

[0001] This utility model relates to the field of land surveying technology, specifically to a planning verification surveying device. Background Technology

[0002] As is well known, land surveying instruments can quickly measure the area, distance, and perimeter of plots of land of any shape.

[0003] Traditional measuring devices have significant limitations in height adjustment. Many devices use fixed-height supports or can only adjust the height by simply splicing or stacking components. This method is not only cumbersome and time-consuming, but most devices can only perform simple horizontal fine-tuning and cannot achieve flexible rotation in all directions and at multiple angles. When faced with complex measurement scenarios, the inability to quickly and accurately adjust the measurement direction forces surveyors to frequently move the entire device to find new measurement angles. This not only increases workload but also easily introduces new measurement errors due to positional deviations during device movement, seriously affecting the reliability and integrity of measurement data. To address these problems, a planning and verification measuring device is proposed. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a planning verification measurement device. This device overcomes the significant limitations of current traditional measurement devices in terms of height adjustment. Many devices use fixed-height supports or can only adjust height through simple splicing or stacking of components. This approach is not only cumbersome and time-consuming, but most devices can only perform simple horizontal fine-tuning and cannot achieve flexible rotation in all directions and at multiple angles. In complex measurement scenarios, due to the inability to quickly and accurately adjust the measurement direction, measurement personnel have to frequently move the entire device to find new measurement angles. This not only increases workload but also easily introduces new measurement errors due to positional deviations during device movement, seriously affecting the reliability and integrity of the measurement data.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a planning verification and measurement device, comprising a fixed plate, a sliding sleeve fixedly connected to the bottom of the fixed plate, a lifting screw rotatably connected to the bottom surface inside the sliding sleeve, a lifting column slidably connected inside the sliding sleeve, the lifting screw threadedly connected to the inside of the lifting column, a rotating base fixedly connected above the lifting column, a cavity opened inside the rotating base, a plurality of balls rotatably connected to the bottom surface inside the cavity, a rotating platform rotatably connected inside the cavity through the balls, a threaded column fixedly connected to the center of the top of the rotating platform, a three-jaw chuck detachably connected above the rotating platform through the threaded column, and a land surveying instrument clamped above the three-jaw chuck.

[0006] Preferably, a first locking bolt is threadedly connected to the left side of the rotating base, the end of the first locking bolt abuts against the side of the rotating table, and a spirit level is provided on the right side of the upper surface of the rotating base.

[0007] Preferably, at least three sets of first rotating ears are fixedly connected to the bottom of the fixed plate, and the bottom of each of the three first rotating ears is rotatably connected to a support leg via a rotating shaft.

[0008] Preferably, each of the three support legs is slidably connected to an extension rod, the bottom of each of the three extension rods is fixedly connected to a conical top foot, and the outer side of each of the three support legs is equipped with a locking device for fixing the extension rod at the connection position with the extension rod.

[0009] Preferably, a sliding ring is slidably connected to the outer side of the sliding sleeve, and a second locking bolt for fixing the sliding ring is threaded to the side of the sliding ring.

[0010] Preferably, at least three sets of second rotating ears are fixedly connected to the outer side of the sliding ring, and each of the three second rotating ears is rotatably connected to a connecting rod via a rotating shaft. The ends of the three connecting rods are rotatably connected to the sides of the three support legs via hinges.

[0011] Preferably, the bottom of the lifting screw passes through the drive column on the bottom surface of the sliding sleeve, and the bottom surface of the drive column has a notch for rotating the screwdriver.

[0012] Compared with existing technologies, the advantages of this invention are as follows: In terms of height adjustment, the lifting screw is rotated by a drive column, and the sliding connection between the lifting column and the sliding sleeve allows for precise adjustment of the land surveyor's height to meet the height requirements of different measurement scenarios. Regarding angle adjustment, ball bearings enable flexible horizontal rotation of the rotating platform within the rotating base, and the adjusted angle can be fixed by the first locking bolt, facilitating quick switching of measurement directions. In terms of stability, three sets of support legs, along with a retractable extension rod and a conical top foot, adapt to different terrains and enhance ground grip. The linkage structure between the sliding ring and the connecting rod further strengthens the support, and the leveling device can be intuitively adjusted via a spirit level to ensure stability and prevent wobbling during measurement. Through optimization of height adjustment, angle adjustment, and stability design, this invention significantly improves the accuracy, flexibility, stability, and adaptability of the measuring equipment, enabling it to provide efficient and accurate measurement functions in various environments and enhancing its practical application value.

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] Reference Figure 1 - Figure 4As shown, a planning verification and measurement device includes a fixed plate 1. A sliding sleeve 2 is fixedly connected to the bottom of the fixed plate 1. A lifting screw 12 is rotatably connected to the bottom surface inside the sliding sleeve 2. A lifting column 3 is slidably connected inside the sliding sleeve 2. The sliding sleeve 2 cooperates with the lifting column 3 to provide guidance and constraint for the up and down sliding of the lifting column 3, ensuring the stable movement of the lifting column 3 in the vertical direction and preventing it from deviating, thereby ensuring the stability of the land surveying instrument 10 during height adjustment. The lifting screw 12 is threaded into the inside of the lifting column 3. A rotating base 4 is fixedly connected above the lifting column 3. A cavity is opened inside the rotating base 4. Several balls 5 are rotatably connected to the bottom surface inside the cavity. A rotating table 6 is rotatably connected inside the cavity through the balls 5. The balls 5 provide rotation support for the rotating table 6. The support allows the rotary table 6 to rotate flexibly in the horizontal direction, replacing sliding friction with rolling friction, which greatly reduces the friction force when the rotary table 6 rotates, making the rotation of the rotary table 6 easier and more flexible. Operators can more easily adjust the measurement direction of the land surveying instrument 10. A threaded column 7 is fixedly connected to the upper center of the rotary table 6, and a three-jaw chuck 9 is detachably connected to the upper part of the rotary table 6 through the threaded column 7. The land surveying instrument 10 is clamped on the upper part of the three-jaw chuck 9. The land surveying instrument 10 can be a Haixingda iRTK20 or Zhonghaida V30, used for planning verification measurement. It can collect data such as plot area, distance, and perimeter. It is the core functional component of the entire measurement device, providing accurate data support for planning verification work.

[0018] Furthermore, a first locking bolt 8 is threadedly connected to the left side of the rotating base 4, and the end of the first locking bolt 8 abuts against the side of the rotating table 6. A level bubble 11 is provided on the right side of the upper surface of the rotating base 4. When installing and adjusting the device, the device is made to reach a horizontal state by adjusting the length of the extension rod 15 of the support leg 14 according to the indication of the level bubble 11, thereby improving the measurement accuracy of the land surveying instrument 10.

[0019] Preferably, at least three sets of first rotating ears 13 are fixedly connected to the bottom of the fixed plate 1. The bottom of each of the three first rotating ears 13 is rotatably connected to a support leg 14 via a rotating shaft. The first rotating ears 13 provide a rotating connection point for the support leg 14, so that the support leg 14 can be unfolded and folded relative to the fixed plate 1, which facilitates the carrying and storage of the device, and at the same time provides stable support for the device after unfolding.

[0020] Specifically, each of the three support legs 14 has an extension rod 15 slidably connected inside. The bottom of each of the three extension rods 15 is fixedly connected to a conical foot 16. The conical design makes it easier to insert into the ground, increasing the contact area and friction between the device and the ground, improving the stability of the device during measurement, and preventing the device from shaking or shifting during measurement. On the outside of each of the three support legs 14, at the connection point with the extension rod 15, there is a locking piece 17 for fixing the extension rod 15. After adjusting the length of the extension rod 15, tightening the locking piece 17 can prevent the extension rod 15 from sliding during measurement, ensuring the stability of the length of the support leg 14, thereby improving the overall stability of the device.

[0021] Furthermore, a sliding ring 18 is slidably connected to the outer side of the sliding sleeve 2, and a second locking bolt 21 for fixing the sliding ring 18 is threaded to the side of the sliding ring 18. By adjusting the position of the sliding ring 18 on the sliding sleeve 2, the connection angle between the connecting rod 20 and the support leg 14 can be changed, thereby driving the support leg 14 to open or close to a suitable angle, so that the device can adapt to different terrains and measurement needs, improve the stability and versatility of the device. Tightening the second locking bolt 21 can prevent the sliding ring 18 from sliding during the measurement process, ensure the stability of the angle of the support leg 14, and thus improve the overall stability of the device.

[0022] Specifically, at least three sets of second rotating ears 19 are fixedly connected to the outer side of the sliding ring 18. Each of the three second rotating ears 19 is rotatably connected to a connecting rod 20 via a rotating shaft. The ends of the three connecting rods 20 are rotatably connected to the sides of the three support legs 14 via hinges. When the sliding ring 18 slides on the sliding sleeve 2, the connecting rods 20 drive the support legs 14 to open or close, adjusting the angle of the support legs 14 so that the device can remain stable under different terrains.

[0023] In one embodiment, the bottom of the lifting screw 12 passes through the drive column 22 on the bottom surface of the sliding sleeve 2. The bottom surface of the drive column 22 has a notch for rotating a screwdriver. The operator can insert a screwdriver into the notch to easily rotate the drive column 22, thereby driving the lifting screw 12 to rotate and realize the lifting operation of the lifting column 3, making height adjustment more convenient.

[0024] Working principle: The three sets of support legs 14 are unfolded via the first rotating lug 13. The position of the sliding ring 18 on the sliding sleeve 2 is adjusted according to the terrain, causing the connecting rod 20 to drive the support legs 14 to open to a suitable angle. The second locking bolt 21 is tightened to fix the sliding ring 18, ensuring stable support. The locking piece 17 is loosened, and the extension rod 15 is stretched or retracted, causing the conical top foot 16 to contact the ground and insert to a certain depth to enhance stability. The level bubble 11 on the rotating base 4 is observed. By adjusting the length of the extension rod 15 of different support legs 14, the level bubble 11 is centered, and the device is in a horizontal state. Finally, the locking piece 17 is tightened to fix the extension rod 15. The land surveying instrument 10 is placed on the three-jaw chuck 9, and the jaws of the three-jaw chuck 9 are adjusted to firmly clamp the land surveying instrument 10, ensuring it will not loosen during measurement. A screwdriver is inserted into the notch at the bottom of the drive column 22, and the drive column 22 is rotated to drive the lifting screw 12 to rotate. 2. The lifting column 3 is threaded together with the sliding sleeve 2 to drive the lifting column 3 to slide up and down along the sliding sleeve 2, thereby adjusting the height of the land surveying instrument 10 until the required measurement height is reached. Loosen the first locking bolt 8 and rotate the rotating table 6. Under the action of the ball bearing 5, the rotating table 6 drives the three-jaw chuck 9 and the land surveying instrument 10 to rotate horizontally within the rotating base 4 and adjust to the target measurement direction. After the measuring instrument is aligned with the measurement target, tighten the first locking bolt 8 so that its end is pressed against the side of the rotating table 6 to fix the rotation angle and avoid rotation during measurement that would affect the accuracy of the data. After completing the above adjustments, operate the land surveying instrument 10 to perform planning verification measurements such as land area, distance, perimeter, etc. After the measurement is completed, loosen the three-jaw chuck 9 to remove the land surveying instrument 10, loosen the locking part 17 to retract the extension rod 15 into the support leg 14, loosen the second locking bolt 21 to move the sliding ring 18 down, and fold the support leg 14 to reduce the size of the device for easy carrying and storage.
