DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-2In the embodiment of the present invention, a rapid positioning device combining an RTK measuring instrument and a total station includes a measuring instrument body and a prism 40. The measuring instrument body includes a centering rod 10, a level bubble 11, a handbook 12, a sliding rod 13 and a receiver 30. Specifically, a ground plug for plugging is provided at the bottom of the centering rod 10. The level bubble 11 for leveling is fixedly connected to one side of the outer wall of the centering rod 10. The sliding rod 13 is slidably connected to the axis position of the top of the centering rod 10. A first locking member for locking the sliding rod 13 is installed adjacent to the centering rod 10 and the sliding rod 13. The outer wall of the centering rod 10 is fixedly connected to the handbook 12. The wall is connected to a clamping member for sliding, and the handbook 12 is clamped on the clamping member. A second locking member for locking with the centering rod 10 is installed on the clamping member. When testing is required, the ground plug at the bottom of the centering rod 10 is inserted into the point to be measured, and the level bubble 11 is observed to keep the centering rod 10 vertical. The sliding rod 13 is adjusted to a suitable position and fixed by the first locking member. The clamping member is then slid to the desired position and locked by the second locking member. The handbook 12 is clamped on the clamping member, and the satellite signal is received by the receiver 30 and transmitted to the handbook 12. Then, the point to be measured can be measured.

[0024] See Figure 2 , an auxiliary component for installing the receiver 30 and the prism 40 is installed on the top of the sliding rod 13, and the auxiliary component includes a bottom plate 20, a support column 21 and a top plate 22. The bottom plate 20 is movably installed at the central axis position of the top of the sliding rod 13, and the support column 21 for connection is fixedly connected to the top ends of the bottom plate 20. The top plate 22 is fixedly connected to the outer wall of the top of the support column 21. The length of the support column 21 is greater than the height of the prism 40;

[0025] See Figure 3 and Figure 5 The bottom of the bottom plate 20, the receiver 30 and the prism 40 are all equipped with docking components for docking. The top of the sliding rod 13, the bottom plate 20 and the top of the top plate 22 are all equipped with mounting components that cooperate with the docking components. The bottom of the mounting component is equipped with an adjustment component for adjusting the bottom plate 20, the receiver 30 and the prism 40. The receiver 30 and the prism 40 can be used separately by matching the docking components thereon with the mounting components on the sliding rod 13. The receiver 30 and the prism 40 can be used in combination by installing the bottom plate 20 on the sliding rod 13 and installing the receiver 30 and the prism 40 on the top plate 22 and the bottom plate 20.

[0026] Specifically, when measurement is required, first, the receiver 30 is used alone to measure ten points. To facilitate subsequent analysis, the coordinates of the points are assumed to be true values. Then, a total station is set up at one of the points, and another point is used as a control point. Next, the receiver 30 and prism 40 are installed on the top plate 22 and the bottom plate 20. The other eight points are measured again using the receiver 30 and the total station. Four measurements are performed, and the coordinate differences △x, △y, and position difference △s are calculated from the measurement results to obtain the average value of the coordinates, thereby improving the accuracy of the coordinates.

[0027] See Figure 5 The mounting assembly includes a mounting block 60, a limiting groove 61 and a plug-in hole 62. The mounting block 60 is fixedly connected to the middle position of the sliding rod 13, the bottom plate 20 and the top outer wall of the top plate 22. The three mounting blocks 60 are located at the same axial position. The limiting grooves 61 for limiting are arranged in a circle and are opened on the inner wall of the mounting block 60. The plug-in holes 62 for plug-in are arranged in a circle and are opened on the inner wall of the mounting block 60. The plug-in holes 62 and the limiting grooves 61 are staggered.

[0028] See Figure 3 and Figure 4 The docking assembly includes a docking block 50 and a plug-in rod 55. The docking block 50 is rotatably connected to the bottom middle position of the base plate 20, the receiver 30 and the prism 40. The outer wall of the docking block 50 is fixedly connected to a plurality of circumferentially arranged limiting guide rails 51 for limiting. The inner wall of the docking block 50 is provided with a plurality of groups of circumferentially arranged sliding holes. The plug-in rod 55 is slidably connected to the inner wall of the sliding hole on the docking block 50, and the inner wall of the docking block 50 is fixedly connected to a sliding seat 54 at the axis position of the sliding hole. A rectangular slide is provided on the inner wall of the sliding seat 54, and a sliding plate 59 is slidably connected to the inner wall of the rectangular slide. The plug-in rod 55 is fixedly connected to the sliding plate 59 away from one end of the axis of the docking block 50 and is slidably connected to the inner wall of the sliding seat 54. When it needs to be fixed, the docking block 50 is inserted into the mounting block 60, and the limiting guide rail 51 is inserted into the limiting groove 61 to limit the plugging direction of the docking block 50.

[0029] The docking assembly also includes a rotating rod 53 and an adjusting screw 58 for driving the plug rod 55 to move. The rotating rod 53 is rotatably connected to the axial position of the docking block 50 and is fixedly connected to the outer wall of the bottom end of the base plate 20, the receiver 30 and the prism 40. The outer wall of the rotating rod 53 is fixedly connected to a plurality of linearly arranged first bevel gears 56. The sliding seat 54 is rotatably connected to the second bevel gear 57 meshing with the first bevel gear 56 near the axial position of one end of the rotating rod 53. The adjusting screw 58 is fixedly connected to the axial position of one end of the second bevel gear 57 and is threadedly connected to the inner wall of the plug rod 55. When the plugging is completed, the rotating base plate 20, the receiver 30 and the prism 40 drive the rotating rod 53 to rotate. At this time, the limiting guide rail 51 is inserted into the limiting groove 61 to align with the limiting guide rail 51. The docking block 50 is limited, and then relative rotation occurs between the rotating rod 53 and the docking block 50, and the rotating rod 53 drives the first bevel gear 56 to rotate, and the first bevel gear 56 drives the second bevel gear 57 to rotate. The rotation of the second bevel gear 57 can drive the adjusting screw 58 to rotate synchronously, and the adjusting screw 58 can drive the plug rod 55 threaded thereon to slide. At this time, the sliding plate 59 slides in the sliding seat 54 to limit the rotation of the plug rod 55, so as to prevent the deflection of the plug rod 55 from affecting the movement of the plug rod 55 driven by the adjusting screw 58, and then drive the plug rod 55 to slide and insert it into the plug hole 62 for fixation, and then complete the installation. When disassembly is required, only the base plate 20, the receiver 30 and the prism 40 need to be reversed.

[0030] Through the provided docking components and installation components, the base plate 20, receiver 30 and prism 40 can be conveniently installed and disassembled. The receiver 30 or the prism 40 can be used alone for detection, or both can be used for detection at the same time. The receiver 30 and the total station are used to synchronously measure the point position. There is no need to first use the total station for detection and then re-measure with the receiver 30. This simplifies the detection steps and improves the convenience of detection.

[0031] See Figure 5 and Figure 6The second piston plate 76 is fixedly connected to the inner wall of the connecting pipe 75, and the second connecting rod 77 is fixedly connected to the top axis position of the second connecting rod 77. The leveling block 78 is fixedly connected to the top axis position of the second connecting rod 77. When the aqueous solution is squeezed into the connecting pipe 75, the aqueous solution in the multiple connecting pipes 75 can be maintained at the same height under the influence of gravity. The second connecting rod 77 and the leveling block 78 can be driven upward by the squeezing of the second piston plate 76 by the aqueous solution, and then the docking block 50 is squeezed upward by the leveling block 78, and the docking block 50 is fine-tuned to keep the docking block 50 vertical.

[0032] When the cam 73 is in the closed position, the first piston plate 73 is pressed against the bottom end of the cam 73 and the first piston plate 73 is pressed against the bottom end of the cam 73 to release the cam 73.

[0033] By setting the adjustment component, the leveling block 78 can be driven to move by water pressure, and the leveling block 78 squeezes the docking block 50 for fine adjustment, thereby maintaining the vertical state of the receiver 30 and the prism 40 when they are set up, thereby improving the accuracy of detection.

[0034] The working principle of the present utility model is as follows: when installation is required, the docking block 50 on the base plate 20, the receiver 30 and the prism 40 is inserted into the mounting block 60, and the limiting guide rail 51 on the docking block 50 can be inserted into the limiting groove 61 to limit the plugging direction of the docking block 50 and limit the deflection of the docking block 50. Then, the base plate 20, the receiver 30 and the prism 40 are rotated to drive the rotating rod 53 to rotate, which can drive the adjusting screw 58 to rotate through the first bevel gear 56 and the second bevel gear 57, and then drive the plug rod 55 to slide and insert into the plug hole 62 for fixation. When the fixation needs to be released, the base plate 20, the receiver 30 and the prism 40 can be reversed.

[0035] At the same time, the docking block 50 squeezes the bottom pressure plate 71 through the squeezing block 52, and then squeezes the aqueous solution into the connecting pipe 75 through the first connecting rod 72 and the first piston plate 73 to squeeze the second piston plate 76, and squeezes the docking block 50 through the second connecting rod 77 and the leveling block 78 to make fine adjustments to keep the docking block 50 vertical;

[0036] When inspection is required, the receiver 30 is installed on the top of the sliding rod 13, and ten points are measured. Then, the total station is set up at one of the points, and the other point is used as a control point. Then, the receiver 30 and the prism 40 are installed on the top plate 22 and the bottom plate 20, and the other eight points are measured again by the receiver 30 and the total station. Four measurements are performed, and the coordinate differences △x, △y and position difference △s of the measurement results are calculated to obtain the average value of the coordinates, thereby improving the accuracy of the coordinates.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
