Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping equipment, and in particular relates to a navigation surveying and mapping instrument. Background Art

[0002] A navigation surveyor is a kind of measuring equipment that uses GPS carrier phase observation for real-time dynamic relative positioning technology. This equipment can receive satellite signals to achieve high-precision positioning, and the positioning accuracy can reach centimeter level. The operating principle of the navigation surveyor is that the base station receiver is set up on a reference point with known or unknown coordinates, and continuously receives all visible GNSS satellite signals; the base station sends the coordinates of the measuring station, pseudo-range observation value carrier phase observation value, satellite tracking status and receiver working status to the mobile station through a wireless data link; the mobile station is initialized first, and after completing the search and solution of the unknown number of the whole week, it enters the dynamic operation;

[0003] This navigation surveying instrument is widely used in aviation, aerospace, military, transportation, resource exploration, communication meteorology, surveying and mapping industries, etc. At the same time, in the surveying and mapping industry, it can be used for engineering star measurement, deformation observation, aerial photogrammetry, ocean measurement and geographic data collection in geographic information systems;

[0004] Most of the navigation surveying instruments on the market now use a secondary rod to extend and retract in the sleeve rod to achieve height adjustment. After the navigation surveying instrument is adjusted to the appropriate position, the secondary rod needs to be fixed in the sleeve rod. The common way of fixing is to fix the secondary rod to the inside of the sleeve rod with a fixing bolt. However, after the fixing bolt contacts the sleeve rod, the force position is relatively concentrated. At the same time, the fixing bolt is made of metal. Therefore, after the fixing bolt contacts the sleeve rod for a long time, surface scratches will appear and the sleeve rod will also be deformed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1 and Figure 2 As shown in , a navigation surveying and mapping instrument comprises:

[0027] A secondary rod 3, a detachable main body 1 is mounted on the top of the secondary rod;

[0028] The inner diameter of the sleeve rod 4 is larger than the outer diameter of the auxiliary rod 3, and the auxiliary rod 3 and the sleeve rod 4 are matching components;

[0029] The auxiliary rod 3 is inserted into the inner part of the sleeve rod 4;

[0030] The auxiliary rod 3 can be extended and retracted in the sleeve rod 4, thereby adjusting the height of the main body 1;

[0031] The tensioning assembly 8 specifically includes a limit sleeve 81, a clamping block 82, a damping block 83 and a screw groove 84. The multiple clamping blocks 82 are fixed to the top of the sleeve rod 4 in an annular shape, and a damping block 83 is fixedly attached to the inner wall of each clamping block 82;

[0032] The bottom end of the sleeve rod 4 is tapered, and the tapered design of the bottom end of the sleeve rod 4 can more conveniently adjust the tilt angle of the sleeve rod 4;

[0033] The outer wall of the clamp block 82 is provided with a screw groove 84, and the outer wall of the clamp block 82 is sleeved with a limit sleeve 81;

[0034] The limiting sleeve 81 and the clamping block 82 are threadedly connected;

[0035] Specifically, the limiting sleeve 81 is rotated in the opposite direction on the clamping block 82, so that the limiting sleeve 81 is separated from the clamping block 82, thereby the clamping block 82 loses the clamping of the auxiliary rod 3, and the auxiliary rod 3 can be pulled out inside the sleeve rod 4 to adjust the position;

[0036] Furthermore, when the auxiliary rod 3 is pulled to a suitable position inside the sleeve rod 4 and the position of the auxiliary rod 3 needs to be fixed, the limiting sleeve 81 is rotated forward on the surface of the clamping block 82, so that the limiting sleeve 81 and the clamping block 82 are in contact with each other, and at the same time, the limiting sleeve 81 constrains the opening angle of the clamping block 82 and retracts it, thereby clamping and fixing the auxiliary rod 3, and the damping block 83 installed on the inner wall of the clamping block 82 increases the friction between the clamping block 82 and the auxiliary rod 3;

[0037] like Figure 1 and Figure 3 As shown in the figure, the clamp 7 is sleeved on the outer wall of the sleeve rod 4, and a fixing bolt 73 is provided at one end of the rubber sheet 71 for adjusting the inner diameter of the clamp 7. A plurality of rubber sheets 71 are fixed at intervals on the inner wall of the clamp 7, and a bubble centering instrument 72 is fixed on one side of the outer wall of the clamp 7;

[0038] Specifically, when the clamp 7 is sleeved on the surface of the sleeve rod 4, the inner diameter of the clamp 7 can be adjusted by rotating the fixing bolt 73, so that the clamp 7 is fixed on the surface of the sleeve rod 4;

[0039] Furthermore, a clamp 6 is installed on the outer wall of the clamp 7, so that the handbook 5 can be installed on one side of the clamp 7. At the same time, the bubble centering instrument 72 can be used to clearly observe whether the navigation surveying instrument is level.

[0040] like Figure 1 and Figure 4 As shown in , a docking assembly 2 is provided between the main body 1 and the auxiliary rod 3, and the docking assembly 2 specifically comprises a threaded rod 21, an internal threaded rotating sleeve 22 and a rotating groove 23, the threaded rod 21 is fixed at the middle position of the bottom wall of the main body 1, and the internal threaded rotating sleeve 22 is movably installed on the surface wall at the top of the auxiliary rod 3 through the rotating groove 23; the threaded rod 21 and the internal threaded rotating sleeve 22 are threadedly connected;

[0041] Specifically, after inserting the threaded rod 21 at the bottom of the main body 1 into the internal threaded rotating sleeve 22, the internal threaded rotating sleeve 22 is rotated to realize the movement of the threaded rod 21 in the internal threaded rotating sleeve 22. When the threaded rod 21 completely overlaps with the internal threaded rotating sleeve 22, the installation of the main body 1 and the auxiliary rod 3 is completed.

[0042] Furthermore, the internal thread rotating sleeve 22 is rotated in the reverse direction, and the threaded rod 21 moves in the reverse direction inside the internal thread rotating sleeve 22. When the threaded rod 21 is completely separated from the internal thread rotating sleeve 22, the disassembly of the main body 1 and the auxiliary rod 3 is completed.

[0043] Working principle: First, hold the navigation surveying instrument by hand and move it to a suitable position, then adjust the position of the auxiliary rod 3 in the sleeve rod 4, and then fix the position of the auxiliary rod 3 in the sleeve rod 4, so that the main body 1 can be adjusted to a suitable position;

[0044] Secondly, the main body 1 is turned on, and the main body 1 is controlled on the handbook 5;

[0045] Finally, the bubble centering instrument 72 is observed to adjust the horizontal position of the navigation surveying instrument, and the surveying work can be started under the action of the main body 1, and finally all the work of the device is completed.
