Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping equipment, and in particular to a surveying and mapping fixed-point device and method suitable for multiple terrains. Background Art

[0002] The surveying and mapping and fixed-point device is an advanced positioning and navigation device that can receive signals from the global navigation satellite system. It measures the time difference in satellite signal transmission and uses satellite orbit calculation algorithms to achieve high-precision position, speed and time information solutions. It is widely used in aerospace, geographic measurement, intelligent transportation and other fields, providing important support for the development of modern society.

[0003] The patent with application number CN202111191750.8 discloses a multi-posture all-terrain geographic information surveying and mapping instrument, including a base, a tripod, and a surveying and mapping instrument body. The lower surface of the surveying and mapping instrument body is fixedly connected to a mounting seat, and the lower surface of the mounting seat is provided with ball grooves evenly distributed in a circular shape. The upper surface of the base is rotatably connected to an adjustment seat, and a fixed groove is provided at the center position of the upper surface of the adjustment seat. A turntable is movably installed inside the fixed groove, and magnetic beads corresponding to the ball grooves are fixedly installed on the upper surface of the turntable. A rotating shaft is welded on the lower surface of the turntable. The structure is simple and can assist in the micro-adjustment of the surveying and mapping instrument, thereby reducing the adjustment time of the surveying and mapping instrument and improving the accuracy of the measurement data.

[0004] With the innovation of positioning and navigation technology, it has gradually replaced traditional tripods and total stations, significantly reducing the workload of surveyors. However, in complex terrain environments, surveyors still need to move around with handheld equipment, especially in complex terrains such as soft soil and steep slopes. Not only is the mobility limited, but there are also safety hazards, increasing operational risks. In addition, traditional measurement methods still require manual driving of steel bars into the measuring points as marks, which increases labor costs, prolongs the surveying cycle, and may introduce errors due to inconsistent operations, affecting the surveying accuracy and reliability.

[0057] In this embodiment, Figure 5-Figure 6As shown, the driving device 220 includes a dual-axis motor 221, a rotating shaft 222 disposed on the output shafts at the front and rear ends of the dual-axis motor 221, and a screw rod 223 that rotates as the rotating shaft 222 rotates;

[0058] Specifically, the dual-axis motor 221 is fixedly connected to the top surface of the fixed plate 211 by bolts, the rotating shaft 222 is coaxially connected to the output shafts at both ends of the dual-axis motor 221, the end of the rotating shaft 222 extends to the inside of the spacing groove 2121, and the left and right ends of the screw rod 223 are respectively rotatably connected to the inner groove walls at the left and right ends of the limiting sliding groove 2120.

[0062] Specifically, the movable bracket 231 is threadedly connected to the outer side of the screw rod 223, the bottom end of the flip frame 232 is rotatably connected to the top end of the movable bracket 231, a frame cam 2320 is integrally formed at the center position of the outer side walls at the front and rear ends of the flip frame 232, a clamping frame 233 for placing the positioning and navigation device 300 is welded and fixed on the inner frame wall of the flip frame 232, and the top end of the connecting rod 234 is rotatably connected to the outer side of the frame cam 2320.

[0063] Furthermore, after the screw rod 223 rotates, the movable bracket 231 mounted on the outside thereof moves to the right inside the limiting slide groove 2120, thereby driving the bottom end of the flip frame 232 to move toward the right side of the limiting slide groove 2120. At this time, the bottom end of the connecting rod 234 remains in a fixed position, and its top moves toward the upper right. When the movable bracket 231 moves to the rightmost side of the limiting slide groove 2120, the flip frame 232 as a whole remains perpendicular to the body of the crawler mobile vehicle 100, and the frame cam 2320 on the flip frame 232 is used to provide a rotation range for the top end of the connecting rod 234.

[0064] In this embodiment, Figure 8-Figure 10 As shown, the dotting device 240 includes a placement plate 241, a squeeze plate 242 disposed inside the placement plate 241, a plurality of first pressure springs 243 disposed on the left side wall of the squeeze plate 242, a plurality of fixed-point steel bars 246 regularly placed inside the placement plate 241, a limit block 244 for limiting the fixed position of the fixed-point steel bars 246, and a pressing portion 247 for pressing down the fixed-point steel bars 246;

[0065] Specifically, the placement plate 241 is fixedly connected to the bottom surface of the fixed plate 211 by bolts, and a plate body groove 2410 for placing the fixed steel bars 246 is opened inside the placement plate 241, and a fixed hole 2411 that passes through the inside and outside is opened on the right groove wall of the plate body groove 2410 of the placement plate 241, and the fixed hole 2411 is opened and closed with two front-to-back symmetrical placement grooves 2412 above the bottom hole wall, and an inner plate slide groove 2413 is opened on the placement plate 241 above the plate body groove 2410.

[0066] Furthermore, the extrusion plate 242 is slidably connected to the inside of the plate body groove 2410, one end of the first pressure spring 243 is fixed on the groove wall of the plate body groove 2410, and the other end is fixed on the outer wall of the extrusion plate 242, and the elastic force of the first pressure spring 243 is used to push the extrusion plate 242 to move toward the fixed hole 2411, and the limit block 244 is slidably connected to the inside of the placement groove 2412, and a second pressure spring 245 is fixed on the outer wall of the limit block 244, and the other end of the second pressure spring 245 is fixed on the groove wall of the placement groove 2412, and the longitudinal section of the limit block 244 is a right-angled trapezoid.

[0067] Furthermore, the placement plate 241 is used to ensure the strength of the overall structure of the marking device 240, and the fixed hole 2411 is used to provide a passage for the fixed steel bar 246. In addition, when the positioning and navigation device 300 is perpendicular to the body of the crawler mobile vehicle 100, the probe rod at its bottom is located directly above the fixed hole 2411, and the first pressure spring 243 pushes the extrusion plate 242 through its own elastic force, and pushes a number of regularly placed fixed steel bars 246 through the extrusion plate 242, thereby pushing the fixed steel bars 246 to directly below the end of the lower pressure bracket 2470. Under the elastic force of the second pressure spring 245, the two sets of limit blocks 244 extend to the inside of the fixed hole 2411, thereby ensuring that the fixed steel bar 246 will not fall from the inside of the fixed hole 2411 without the action of external force.

[0068] In this embodiment, Figure 8-Figure 11 As shown, the pressing portion 247 includes a pressing bracket 2470, a third pressure spring 2473 that pulls the pressing bracket 2470 upward by its own elastic force, and a plurality of pulling ropes 2474 connected to the moving bracket 231 and the pressing bracket 2470;

[0070] Furthermore, the third pressure spring 2473 is sleeved on the outside of the connecting rope 2472, one end of the third pressure spring 2473 is fixed to the outer wall of the sliding plate 2471, and the other end is fixed to the right section of the groove wall of the sliding groove 2413 in the plate. The elastic force provided by the third pressure spring 2473 is used to push the sliding plate 2471 to move to the left, and the pulling rope 2474 bypasses the outside of the bottom cross bar of the downward extension bracket 215.

[0071] Furthermore, after the dual-axis motor 221 rotates in the opposite direction, the mobile bracket 231 moving toward the left side drives the flip frame 232 and the positioning navigation device 300 to restore their positions. At this time, the mobile bracket 231 moving toward the left side pulls the downward pressure bracket 2470 through the pulling rope 2474 to move downward in the hole wall of the fixed hole 2411, and drives the fixed steel bar 246 to pass through the limit block 244 and insert into the ground, thereby completing the determination of the point position. In the process of the mobile bracket 231 moving to the right, the sliding plate 2471 moves to the left inside the slide groove 2413 in the plate under the elastic force of the third pressure spring 2473, and pulls the downward pressure bracket 2470 to move upward in the hole wall of the fixed hole 2411 through the connecting rope 2472.

[0072] Finally, in actual use, a protective cover plate may be installed on the top of the flip frame 232 to protect the positioning and navigation device 300 from being affected by the external environment during the movement of the crawler mobile vehicle 100 .

[0073] The present invention also provides a method for surveying and mapping and fixing points applicable to multiple terrains, using the above-mentioned surveying and mapping and fixing points device applicable to multiple terrains, comprising the following steps:

[0074] S1. First, the operator turns on the positioning and navigation device 300 and uses a handheld receiver to receive information from the positioning and navigation device 300 in real time;

[0075] S2, then, control the crawler mobile vehicle 100 to move in the area to be surveyed and mapped, and when approaching the target point, reduce the moving speed of the crawler mobile vehicle 100;

[0076] S3, then, the dual-axis motor 221 is started to drive the rotating shafts 222 at both ends to rotate, and when the main bevel gear 224 at the end of the rotating shaft 222 conflicts with the auxiliary bevel gear 225, the auxiliary bevel gear 225 and the screw rod 223 are driven to rotate;

[0077] S4, after the screw rod 223 rotates, the movable bracket 231 sleeved on the outside thereof moves rightward inside the limiting slide groove 2120, and drives the bottom end of the flip frame 232 to move toward the right side of the limiting slide groove 2120;

[0078] S5. At this time, the bottom end of the connecting rod 234 remains fixed in position, and the top end thereof moves toward the upper right. When the movable bracket 231 moves to the rightmost side of the limiting slide groove 2120, the entire flip frame 232 remains vertical to the body of the crawler mobile vehicle 100.

[0079] S6. Next, the operator adjusts the position of the crawler moving vehicle 100 again according to the positioning information of the positioning navigation device 300, and stops when the positioning navigation device 300 moves to the top of the point;

[0080] S7, then, the dual-axis motor 221 is controlled to rotate in the opposite direction, and the mobile bracket 231 moves toward the left, driving the flip frame 232 and the positioning navigation device 300 to restore their positions;

[0081] S8. At this time, the mobile bracket 231 moving toward the left side pulls the pressing bracket 2470 to move downward in the hole wall of the fixed hole 2411 through the pulling rope 2474, and drives the fixed-point steel bar 246 to pass through the limit block 244 and then insert into the ground, thereby completing the determination of the point position.
