Description

Technical Field

[0001] This utility model relates to the field of geographic surveying and mapping technology, and in particular to a vertical geographic surveying and mapping device that is easy to fix. Background Technology

[0002] Surveying and mapping, literally understood as measurement and drawing, is based on computer technology, optoelectronic technology, network communication technology, space science, and information science. It utilizes global navigation satellite positioning systems, remote sensing, and geographic information systems as its core technologies. It selects existing feature points and boundaries on the ground and obtains graphic and location information reflecting the current state of the ground through measurement methods for use in engineering construction, planning and design, and administrative management. Vertical surveying instruments are used in the surveying process. Simply put, a vertical surveying instrument is an instrument and device designed and manufactured for data acquisition, processing, and output in surveying operations. It includes various instruments for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry, required for measurement work during the planning, design, construction, and operation management phases of engineering construction.

[0003] When using a surveying instrument for measurement, the instrument is supported by three support rods at the bottom. However, these three support rods cannot guarantee the stability of the surveying instrument at the top, resulting in poor fixation of the device. When measuring on uneven ground, the device is prone to tilting and falling over, causing damage. In addition, the instability of the support rods and their tendency to sway can also lead to errors in the measurement results. To address these issues, we propose a vertical geographic surveying device that is easy to fix. Utility Model Content

An adjusting plate is movably connected between the U-shaped fixed rods. A flipping groove is opened on the side of the adjusting plate away from the fixed cone. A rotating shaft is fixedly installed in the flipping groove. A flipping plate is connected to the flipping groove through the rotating shaft. A reinforcing threaded cone is threadedly connected to the flipping plate on the side away from the fixed cone.

[0006] Preferably, the top of the fixed cone is movably provided with a rotating fixing handle, and the bottom end of the rotating fixing handle contacts the support rod, so that the fixed cone is movably set at the bottom of the support rod by rotating the fixing handle.

[0007] Preferably, the U-shaped fixing rod is provided with a plurality of first holes evenly distributed, the adjusting plate is provided with an arc-shaped groove that matches the outside of the fixing cone, and the adjusting plate moves to the outside of the fixing cone through the arc-shaped groove.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the apparatus includes a surveying instrument 10 and a support rod 11. A base plate 12 is installed at the bottom of the surveying instrument 10. The support rod 11 is connected to the bottom of the base plate 12 via a rotating seat 13. A fixed cone 20 is movably sleeved at the bottom of the support rod 11. The top of the fixed cone 20 is a hollow open structure, and the bottom of the fixed cone 20 is a pointed structure. Two U-shaped fixed rods 21 are fixedly installed on the bottom of the fixed cone 20 near the base plate 12. An adjusting plate 30 is movably connected between the U-shaped fixed rods 21. The adjusting plate 30 is a square plate structure. A flip groove 31 is opened on the side of the adjusting plate 30 away from the fixed cone 20. A rotating shaft 32 is fixedly installed in the flip groove 31. A flip plate 33 is connected to the flip groove 31 via the rotating shaft 32. A reinforcing threaded cone 34 is threadedly connected to the flip plate 33 on the side away from the fixed cone 20.

[0022] By flipping the flip plate 33 in the flip groove 31 around the rotation axis 32, the reinforcing threaded cone 34 on the flip plate 33 is kept perpendicular to the ground. Then, by rotating the handle 39, the reinforcing threaded cone 34 is rotated, causing the reinforcing threaded cone 34 to descend and support the ground, thereby improving the stability of the support rod 11.

[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 4The U-shaped fixing rod 21 is evenly provided with several first holes 23. The adjusting plate 30 is provided with an arc-shaped groove 35 that matches the outside of the fixing cone 20. The adjusting plate 30 moves to the outside of the fixing cone 20 through the arc-shaped groove 35. The adjusting plate 30 is provided with a movable hole 36 that matches the size of the U-shaped fixing rod 21 on the side close to the fixing cone 20. The U-shaped fixing rod 21 moves through the movable hole 36. The adjusting plate 30 is provided with second holes 37 that match the size of the first holes 23 at both ends away from the arc-shaped groove 35. The second holes 37 are connected to the movable holes 36. The first holes 23 and the second holes 37 are connected by a pin 38.

[0024] The adjusting plate 30 is adjusted up and down on the U-shaped fixing rod 21 using the movable hole 36 on the adjusting plate 30. After adjusting to the appropriate position, the pin 38 passes through the second hole 37 and enters the first hole 23 on the U-shaped fixing rod 21. The pin 38 is used to fix the position of the adjusting plate 30 on the U-shaped fixing rod 21.

[0025] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The top of the fixed cone 20 is movably provided with a rotating fixed handle 22, and the bottom end of the rotating fixed handle 22 contacts the support rod 11. The fixed cone 20 is movably set at the bottom of the support rod 11 by rotating the fixed handle 22. The top of the reinforcing threaded cone 34 is fixedly installed with a rotating grip 39.

[0026] Rotate the rotating fixing handle 22 to release the fixing cone 20 and the support rod 11 from the fixing support, adjust the distance between the fixing cone 20 and the support rod 11 so that the surveying instrument 10 on the top of the base plate 12 is adjusted to a suitable height, and then rotate the rotating fixing handle 22 again to fix the fixing cone 20 to the bottom of the support rod 11.

[0027] Working principle: When in use, the three support rods 11 are unfolded by the rotating seat 13 under the base plate 12. Then, the worker rotates the rotating fixing handle 22 to loosen the rotating fixing handle 22 and release the fixing cone 20 and the support rod 11 from the fixing support. The distance between the fixing cone 20 and the support rod 11 is adjusted so that the surveying instrument 10 on the top of the base plate 12 is adjusted to a suitable height. Then, the rotating fixing handle 22 is rotated again to fix the fixing cone 20 to the bottom of the support rod 11.

[0028] After the fixed cone 20 is supported by the ground, the position of the adjusting plate 30 on the U-shaped fixed rod 21 is adjusted. The movable hole 36 on the adjusting plate 30 is used to adjust the position up and down on the U-shaped fixed rod 21. After adjusting to the appropriate position, the pin 38 passes through the second hole 37 and enters the first hole 23 on the U-shaped fixed rod 21. The position of the adjusting plate 30 on the U-shaped fixed rod 21 is adjusted by the pin 38 so that the reinforcing threaded cone 34 connected to the adjusting plate 30 contacts the ground for support. Then, the rotating shaft 32 flips the rotating plate 33 in the flipping groove 31 so that the reinforcing threaded cone 34 on the rotating plate 33 remains perpendicular to the ground. Then, the rotating handle 39 rotates the reinforcing threaded cone 34, causing the reinforcing threaded cone 34 to descend and support the ground, improving the stability of the support rod 11.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
