Description

Technical Field

[0001] The present invention relates to the technical field of forestry design and planning, and specifically to a surveying and mapping device for forestry design and planning. Background Art

[0002] Forestry resources are an important part of China's natural resources. The development of forestry is not only related to ecological construction work, but also has an important impact on social and economic development. Therefore, precise surveying and mapping are required for forestry design and planning.

[0003] The invention disclosed in the publication number CN118499635A discloses a surveying and mapping device for forestry design and planning. This application initially levels by means of the cooperation between a fixed frame and a level, drives a U-shaped groove block to rotate around a first rotating shaft through a first angle adjustment component to adjust the angle, drives a positioning frame to rotate around a second rotating shaft through a second angle adjustment component to adjust the angle, measures the offset angle of the positioning frame of the device after changing positions based on the gyroscopic effect by a gyroscopic positioning device, displays the angle measured by the gyroscopic positioning device through an angle display component, and fixedly installs a laser by means of the cooperation between a clamping component and a connecting cylinder and a connecting ring, and only requires the initial use of a level.

[0004] However, in the above solution, only the setting operation of the level is carried out to simplify the operation steps of the level. Since one of the items in forestry surveying and mapping is elevation surveying, which includes the use of instruments such as levels, total stations, and altimeters, etc. However, the requirements for the forestry landform are extremely high before the use of such instruments. The elevation surveying of forestry is a long-term detection process, and the above solution ignores this specific factor of the landform. Therefore, there is no clear reference point, and correspondingly, the reference point cannot be effectively protected. Summary of the Invention

[0042] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0043] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention.

[0044] Some embodiments of the present invention provided for a surveying and mapping device for forestry design and planning will be described below in conjunction with the accompanying drawings. Embodiment 1:

[0045] Combined with Figures 1 - 10 As shown, a surveying and mapping device for forestry design and planning provided by the present invention includes a crawler-type climbing vehicle 100 and a leveling instrument 600, a suspension mechanism 200 installed on the crawler-type climbing vehicle 100, a support mechanism 300 installed on the suspension mechanism 200, a base point positioning assembly 400 assembled on the support mechanism 300, and a self-calibration mechanism 500 installed in the support mechanism 300.

[0046] The suspension mechanism 200 includes a hydraulic component 210, a cross beam 220, a first chuck 230, a reset assembly 240, a suspension 250, and a second chuck 260. The support mechanism 300 includes a bottom frame 310, a clamping plate 320, a bearing 330, a linkage rod 340, a limiting member 350, a guide rod 360, and a first spring 370. The base point positioning assembly 400 includes a load-bearing screw 410, a benchmark 420, and a second spring 430. The self-calibration mechanism 500 includes a locking assembly 510, a load-bearing assembly 520, and a driving assembly 530. The locking assembly 510 further includes a bracket 511, a sling 512, a compression spring 513, a pressing member 514, a pull rod 515, and a screw sleeve 516. The load-bearing assembly 520 further includes a column 521, a pin 522, a clamping sleeve 523, and a stud 524. The driving assembly 530 further includes a chassis 531, an end tube 532, a clamping seat 533, a dual-axis motor 534, and a distance control frame 535.

[0047] Among them, the crawler-type climbing vehicle 100 is used to climb mountainous areas in forest areas and provides a stable support platform for subsequent various instruments;

[0048] The suspension mechanism 200 includes a hydraulic component 210 installed on the crawler climbing vehicle 100, a suspension 250 installed on the hydraulic sub-rod inside the hydraulic component 210, a crossbeam 220 fixedly installed at the top of the mother rod of the hydraulic component 210, two first chucks 230 fixedly installed at both inner ends of the crossbeam 220, two second chucks 260 fixedly installed on the suspension 250, and a reset component 240 movably installed on the first chuck 230 and the second chuck 260;

[0049] The reset component 240 consists of a telescopic mother rod, a telescopic sub-rod, and a sub-spring arranged inside the telescopic mother rod;

[0050] The support mechanism 300 includes a bottom frame 310 installed on the suspension 250, two clamping plates 320 movably installed on the bottom frame 310, and a linkage rod 340 arranged in the holes of the bottom frame 310;

[0051] The base point positioning component 400 includes a load-bearing screw 410 installed outside the linkage rod 340, a second spring 430 arranged inside the load-bearing screw 410, and a benchmark 420 movably installed inside the load-bearing screw 410;

[0052] Two screw holes are opened in the end pipe at the top of the load-bearing screw 410, and fastening bolts adapted to be pressed against the linkage rod 340 are arranged in the screw holes;

[0053] The self-calibration mechanism 500 includes a locking component 510 installed between the two clamping plates 320, a driving component 530 arranged at the bottom of the locking component 510, and a pressure-bearing component 520 installed inside the locking component 510;

[0054] The level 600 is installed on the pressure-bearing component 520 and is used for surveying and mapping the elevation of forest mountain areas.

[0055] Instruments such as traditional levels, total stations, and altimeters need to be calibrated and adjusted using a support frame when used in forest mountain areas. However, using a support frame requires cumbersome adjustment of each instrument, and the adjustment period is long. Moreover, the compressive strength of the support frame is relatively low, and it is prone to tipping due to human factors or mountain slope airflows. At the same time, the lens of the instrument is prone to jitter in the airflow.

[0056] In addition, the surveying and mapping of the elevation of forest mountains is a long-term process. Therefore, a unified base point is required for the surveying and mapping of each instrument. However, in traditional surveying and mapping methods, the base points on the mountain do not have protection and bearing capacity, which will affect the periodic surveying and mapping of subsequent instruments.

[0057] The device provides a mobile platform for autonomous calibration through various instruments. After the crawler climbing vehicle 100 is moved to the designated position in the forest mountain area via cloud control, the stopped crawler climbing vehicle 100 can provide a sufficiently stable support platform for the above-mentioned components. When instruments such as a level, a total station, and an altimeter are installed on the top of the column 521, the bracket 511 and the sling 512 installed outside the column 521 can cooperate with the drive assembly 530 in a counterweight state to provide automatic calibration for each assembled instrument, and through the opening and closing control of the stud 524 on the combined tie rod 515 and the pressing member 514, finally, each calibrated instrument can be fixed. After the instrument is calibrated, the hydraulic sub-rod in the hydraulic member 210 descends downward, and the suspension 250 installed on its top will drive the bottom frame 310 and the linkage rod 340 to descend until the load-bearing screw 410 installed outside the linkage rod 340 is driven and drilled into the ground. The erected load-bearing screw 410 can serve as the support body of the benchmark, and finally, the benchmark 420 will be quickly bounced up by the second spring 430. At this time, the benchmark 420 and the load-bearing screw 410 in the extended state can set multiple surveying bases in the wild mountain area, and at this time, the base can be protected from foreign object impacts. Embodiment 2:

[0058] Combined with Figures 4 - 7 As shown, on the basis of Embodiment 1, the support mechanism 300 further includes a bearing 330 fixedly installed in the internal hole of the bottom frame 310. The linkage rod 340 is installed in the bearing 330. A guide rod 360 is installed outside the clamping plate 320. A limiting member 350 is installed outside the bottom frame 310 and a first spring 370 is arranged on the rod body of the guide rod 360;

[0059] A limiting slideway is opened inside the limiting member 350;

[0060] The guide rod 360 is composed of a rectangular cushion block and a T-shaped rod body, and the T-shaped rod body is adapted to penetrate into the inside of the limiting member 350. The bottom of the first spring 370 bears on the bottom end of the T-shaped rod body, and the top of the first spring 370 bears on the bottom of the limiting member 350;

[0061] A cross-shaped jack is opened at the top end of the linkage rod 340, and a cylindrical jack adapted to the benchmark 420 is opened inside the linkage rod 340.

[0062] The length of the two end plates of the bottom frame 310 is twice the length of the clamping plate 320. Therefore, when a counterweight assembly is arranged inside the bottom frame 310, the two clamping plates 320 movably installed on the two end plates of the bottom frame 310 can provide calibration adjustment force for the instrument to be assembled, and finally, it can effectively ensure that the instrument can be quickly positioned and calibrated in the mountain area after assembly.

[0063] By installing the linkage rod 340 inside the bearing 330, after the nut on the end pipe 532 is adjusted and rotated by a wrench, the distance control frame 535 that is pushed downward can drive the entire double-shaft motor 534 to descend. Eventually, the bottom transmission shaft of the double-shaft motor 534 will be docked towards the double-shaft motor 534. After docking, the linkage rod 340 can provide driving force for the load-bearing screw 410 to be assembled. Eventually, the entire base positioning assembly 400 that is rotating at high speed can drill into the ground at the selected coordinates. At this time, the load-bearing screw 410 drilled into the ground can provide effective compressive protection for the benchmark 420, so as to provide guidance for the long-term surveying of various instruments. Embodiment Three:

[0064] Combined with Figure 9 As shown, on the basis of Embodiment 1, the locking assembly 510 includes a bracket 511 movably installed between two clamping plates 320, a lifting tool 512 installed on the bracket 511, a compression spring 513 connected to the lifting tool 512, a pressing member 514 movably installed on the rod body of the bracket 511, a pull rod 515 movably connected inside the pressing member 514, and a screw sleeve 516 movably connected to the bottom end of the pull rod 515;

[0065] The lifting tool 512 is composed of two U-shaped clamping members and a circular cushion plate;

[0066] The bottom end of the screw sleeve 516 is provided with a cross-shaped slot;

[0067] The load-bearing assembly 520 includes a column 521 installed inside the bracket 511, a pin 522 inserted inside the column 521, two clamping sleeves 523 installed at the bottom of the column 521, and a stud 524 movably installed inside the two clamping sleeves 523;

[0068] The stud 524 is adapted to penetrate through the inside of the screw sleeve 516.

[0069] Using multiple bolts to fix the two clamping sleeves 523 clamped at the top end of the stud 524 to the bottom of the column 521. At this time, the stud 524 can be limited and clamped. When the nut on the end pipe 532 moves upward, at this time, the compression spring 513 will cause the distance control frame 535 to lift upward, and the double-shaft motor 534 that is bearing the load will lift upward. Eventually, the top transmission shaft of the double-shaft motor 534 will be docked with the stud 524. At this time, the rotating stud 524 will cause the screw sleeve 516 to lift and lower stably. At this time, the two pull rods 515 movably installed on the screw sleeve 516 can simultaneously push the two pressing members 514 to extend in the same direction, so as to effectively ensure that the device provides calibrated locking for the instrument installed at the top of the column 521. Embodiment Four:

[0070] Combined with Figure 9 and Figure 10As shown in the above embodiment, the driving assembly 530 includes a chassis 531 installed outside the compression spring 513, an end pipe 532 fixedly installed at the bottom of the chassis 531, a clamp seat 533 movably installed inside the chassis 531, a dual-axis motor 534 installed inside the clamp seat 533, and a distance control frame 535 installed outside the clamp seat 533;

[0071] A nut that bears on the distance control frame 535 is provided outside the end pipe 532, and cross-shaped plugs are provided on both the top and bottom drive shafts of the dual-axis motor 534.

[0072] By installing the dual-axis motor 534 inside the clamp seat 533, at this time, the center of gravity of the dual-axis motor 534 and the clamp seat 533 assembled inside the chassis 531 can remain constant after repeated lifting and lowering. The overall driving assembly 530 with a constant center of gravity is suspended directly below each assembly instrument by the compression spring 513. At this time, the driving assembly 530 in a suspended state can act as a counterweight assembly to provide a calibration force for the instrument. Through the centering calibration of the counterweight module, the rapid calibration of the instrument after assembly can be improved.

[0073] The working principle and usage process of the present invention: First, use a towing vehicle to transport the device to the periphery of the forest area, and then control the tracked climbing vehicle 100 to climb along the route of the forest area through the cloud until the tracked climbing vehicle 100 stops after the device moves to the designated coordinates in the forest area.

[0074] At this time, the position where the device is located is the base point position with the surveyed elevation. Then, install devices such as a level 600, a total station, and an altimeter on the top of the column 521, and use the pin 522 to load and unload the above instruments in the order of use. When the instruments are assembled, the instruments supported by the column 521 can perform surveying operations on the mountainous area of the forest area at the selected base point position. After the instruments are pre-installed, the user can directly use a wrench to adjust the nut outside the end pipe 532. At this time, the distance control frame 535 lifted by the compression spring 513 can drive the dual-axis motor 534 to lift upward until the shaft rod at the top of the dual-axis motor 534 is inserted into the end of the bottom of the stud 524. With the start of the dual-axis motor 534, the driven screw sleeve 516 will cooperate with the two pull rods 515 and the two pressing members 514 to relax the two clamping plates 320. After the relaxation, the instrument can obtain the load calibration of the overall self-calibration mechanism 500. At this time, the supported instrument can achieve rapid calibration at the base point position under the load state of the self-calibration mechanism 500, thus avoiding the drawbacks of cumbersome calibration adjustment of the instrument in traditional operations.

[0075] When the instrument is calibrated and fixed by two clamping plates 320, the operator can use a wrench to adjust the nut outside the end tube 532 to rotate counterclockwise until the clamping seat 533 drives the whole dual-axis motor 534 to descend until the transmission shaft at the bottom of the dual-axis motor 534 is inserted into the linkage rod 340. At this time, the load-bearing screws 410 installed on the linkage rod 340 by two bolts can be driven. At the same time, for the hydraulic component 210 in operation, the internal hydraulic sub-rod will descend. With the elastic support of the two groups of reset components 240, the whole support mechanism 300 installed on the suspension 250 can stably descend until the high-speed rotating load-bearing screws 410 drill into the selected base point on the ground. Then, loosen the two bolts in the load-bearing screws 410. As the hydraulic sub-rod in the hydraulic component 210 resets, at the moment when the linkage rod 340 withdraws from the inside of the load-bearing screws 410, the marking rod 420 will quickly bounce upward under the action of the second spring 430. At this time, the marking rod 420 erected upward can provide a marking rod, that is, a marker, for the above-mentioned calibrated instrument, thus facilitating the long-term surveying and mapping of each instrument at the same base point. At the same time, the ejected marking rod can also be effectively protected to avoid damage caused by the impact of organisms or foreign objects, thereby ensuring the comparability and accuracy of subsequent measurement data.

[0076] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
