Description

Technical Field

[0001] The utility model relates to the technical field of measuring rods, in particular to an RTK measuring rod. Background Art

[0002] An RTK survey pole is a very useful tool in land surveying, construction surveying and other applications that require high-precision position data. It uses real-time kinematic positioning system technology to provide high-precision positioning data. An RTK survey pole usually consists of a telescopic pole and a survey instrument equipped with a GPS receiver.

[0003] Currently, when RTK instruments are in use, they are controlled to rotate and measure from different directions. The method of changing the measuring direction is mostly done by staff directly rotating the measuring rod as a whole to drive the RTK instrument to rotate and realize measurement from different directions.

[0004] Although the above measurement method can achieve measurement from different directions by controlling the overall rotation, it is difficult to put it back in the original position after the overall rotation changes the measurement direction of the RTK instrument. At this time, it will be offset from the original base point. The positioning accuracy of the RTK pole depends on the distance and relative position to the base station. If the RTK pole is offset from the original base point, it may cause an increase in positioning error, which may affect measurement, navigation or other applications that require accurate position information. Therefore, we propose an RTK measuring pole to solve this problem. Utility Model Content

[0030] In a preferred embodiment, a detachable RTK instrument 4 is installed on the upper surface of the mounting plate 32, and a threaded column 5 is fixedly connected to the top of the mounting plate 32.

The RTK instrument 4 is connected to the threaded column 5, so that the RTK instrument 4 can be stably mounted on the mounting plate 32 for use.

[0031] In a preferred embodiment, the outer surface of the cylinder 1 is fixedly connected to the connecting plate 6, the inside of the connecting plate 6 is slidably connected to the plug-in rod 7, the outer surface of the plug-in rod 7 is fixedly connected to the positioning plate 8, one side of the positioning plate 8 is fixedly connected to the first spring 9, one end of the first spring 9 is fixedly connected to the connecting plate 6, and a positioning hole 10 is provided on the outer surface of the ruler rod 2, and the plug-in rod 7 is inserted into the inside of the positioning hole 10. In actual use, the position of the RTK instrument 4 will be adjusted according to the needs of use, so the ruler rod 2 is slidably installed inside the cylinder 1, and the plug-in rod 7 is inserted into the inside of the ruler rod 2 to position the ruler rod 2 so as to move the RTK instrument 4 to a suitable height and use it stably.

[0032] In a preferred embodiment, a disc 11 is slidably mounted on the outer surface of the cylinder 1, and a connecting rod 12 is rotatably connected to the bottom of the disc 11, one end of the connecting rod 12 is fixedly connected to a support block 13, and the outer surface of the connecting rod 12 is fixedly connected to a rectangular plate 14, a threaded hole is provided inside the rectangular plate 14, and a stud 15 is threadedly connected to the inside of the threaded hole, one end of the stud 15 is fixedly connected to a conical rod 16, and the top of the stud 15 is fixedly connected to a rotating seat 17. To ensure the stable use of the device, a connecting rod 12 is rotatably mounted on the bottom of the disc 11, a support block 13 and a stud 15 are mounted on one end of the connecting rod 12, and a conical rod 16 is fixedly mounted on the bottom of the stud 15. Through the support block 13, the device can be placed on a cement ground for use. If it is on the land, the conical rod 16 can be inserted into the soil to support the use of the device.

[0033] When the device is carried to the location where it is needed, it is necessary to first unfold the connecting rod 12 and contact the supporting block 13 or the tapered rod 16 to the ground to support the device. For easy operation, a squeezing mechanism 18 is installed on the bottom plate of the rotating disk 31. The squeezing mechanism 18 includes a squeezing rod 181 and a magnet 182. The outer surface of the cylinder 1 is fixedly connected to the limiting circular plate 19, and the outer surface of the cylinder 1 is fixedly connected to the magnet 182. An annular groove 20 is provided on the upper surface of the disk 11, and the inner part of the annular groove 20 is slidably connected to the squeezing rod 181. The bottom of the rotating disk 31 is fixedly connected to the hollow bin 21, and the inner bottom of the hollow bin 21 is fixedly connected to the second Spring 22, one end of the second spring 22 is fixedly connected to the extrusion rod 181. In actual use, the disc 11 is slidably installed on the outer surface of the cylinder 1, and the hollow bin 21 is fixedly installed at the bottom of the rotating disk 31. The second spring 22 is fixedly installed inside the hollow bin 21. One end of the second spring 22 is fixedly connected to the extrusion rod 181. By controlling the rotation of the rotating disk 31, the extrusion rod 181 is moved to the disc 11. Under the action of the second spring 22, the extrusion rod 181 squeezes the disc 11 and moves the disc 11 downward, so that the connecting rod 12 is unfolded to support the device and make the device stable in use.

[0034] Specifically, the working process or working principle of an RTK measuring rod is as follows: currently, when the RTK instrument is in use, the RTK instrument will be controlled to rotate to measure from different directions. The method of changing the measuring direction is mostly done by the staff directly rotating the measuring rod as a whole to drive the RTK instrument to rotate and realize measurement from different directions.

[0035] Although the above-mentioned measurement method can be realized from different azimuths by controlling the overall rotation, it is difficult to put it in the original position after the overall rotation is changed to change the measurement orientation of the RTK instrument. At this time, it will be offset from the original base point. The positioning accuracy of the RTK rod depends on the distance and relative position with the base station. If the RTK rod is offset from the original base point, it may cause an increase in positioning error, which may affect measurement, navigation or other applications that require accurate position information. Therefore, this device is designed to solve this problem. The device is carried to the place where it is needed, and then the RTK instrument 4 is fixedly installed on the top of the mounting plate 32. In actual use, the position of the RTK instrument 4 will be adjusted according to the usage. By pulling the ruler rod 2 to move, the ruler rod 2 is pulled out from the inside of the cylinder 1. After determining the position of the RTK instrument 4, the plug-in rod 7 is inserted into the inside of the ruler rod 2, and the ruler rod 2 can be positioned to meet the use.

[0036] The RTK instrument 4 is used to detect the location. If it is necessary to detect from different directions, the detection direction of the RTK instrument 4 needs to be changed. At this time, the rotating disk 31 is rotated. Since a multi-section telescopic rod 33 is fixedly installed between the rotating disk 31 and the mounting plate 32, the mounting plate 32 can be driven to rotate, so as to change the detection direction of the RTK instrument 4 and realize detection from different directions by the RTK instrument 4.

[0037] Before using the device, in order to ensure the stable use of the device, the connecting rod 12 needs to be unfolded and used. The support block 13 is placed on the ground, and then the rotating disk 31 is controlled to rotate, and the squeezing rod 181 at the bottom position of the rotating disk 31 is moved to the inside of the annular groove 20 on the upper surface of the disk 11. The squeezing rod 181 will be pushed by the second spring 22, and the squeezing rod 181 will rotate on the disk 11 to move the disk 11 downward, and the disk 11 will be pressed to the position of the magnet 182, and the disk 11 will be adsorbed by the magnet 182 to position the disk 11. At this time, the connecting rod 12 will rotate under the downward squeezing of the disk 11, so that the connecting rod 12 is unfolded to support the device and ensure the stable use of the RTK instrument 4.

[0038] The connecting rod 12 of the device and the disc 11 are provided with damping rotation, and the connecting rod 12 can be limited so that the connecting rod 12 can stably support the device and meet the requirements of use.
