[0013] The present invention also discloses an engineering surveying and mapping method, which uses the above-mentioned engineering surveying and mapping equipment and comprises the following steps: S1. First, the staff places the column rod at a preset point, and then according to the inclination state of the counterweight block and the connecting rope when hanging, the staff can adjust the position of the column rod, so as to adjust the column rod to a state perpendicular to the ground. When the column rod is adjusted to a vertical state, the electric telescopic rod can be started, and the output end of the electric telescopic rod drives the movable circular plate to slide toward the ground along the outer wall of the column rod. A through hole with a diameter larger than the spur rack is provided on the top of the movable circular plate. During the downward movement of the movable circular plate, the movable circular plate contacts the spur gear through the spur rack, thereby driving the spur gear to drive the worm to rotate, thereby driving the worm gear to drive the rectangular rod to rotate. When the spur gear is separated from the spur rack, the rectangular rod rotates thirty degrees, so that the three rectangular rods are supported downward in an unfolded state, without the need for manual operation by the staff, thereby improving the overall practicality of the device. S2. When the ground is uneven, the rectangular rod moves downward to support and drives the support rod to move synchronously. When the supported ground is uneven, the support rod encounters resistance during the descent process and squeezes the first spring to slide relative to the rectangular rod, so that the support rod can perform adaptive support according to the flatness of the ground, so that the support rod can fit the ground more closely, thereby enhancing the support and fixation of the device on the uneven ground, without the need for frequent adjustments by the staff, thereby improving the overall practicality of the device; S3, when the support rod moves inside the rectangular rod, it drives the fixed block to move, because the top of the plug block and the bottom of the movable block are provided with inclined surfaces, so that the fixed block contacts the movable block through the inclined surface of the top of the plug block during the movement, and under the action of the inclined surface, the movable block is pushed to drive the slider to move into the second sliding groove, and when the plug block is separated from the movable block, the movable block is reset under the action of the second spring to support the bottom of the plug block, thereby forming a limit on the position of the support rod after contraction, thereby ensuring the stability and position accuracy of the support rod after contraction, thereby ensuring the stability of the adaptive support of the device; S4, the elastic coefficient of the third spring is greater than the elastic coefficient of the second spring, when the support rod stops moving relatively, the end of the plug block is located at one side of the movable block, and the slot inside the movable block is docked with the plug block, the slot moves toward the plug block under the push of the second spring, and when the slot is completely aligned with the plug block, the plug block is limited by the slot inside the movable block. When there is a deviation between the slot and the plug block, the slot moves toward the plug block, and the plug block contacts it through the slot and the buffer inclined surface to form an outer eight-character shape during the docking process. Under the action of the inclined surface, the position of the movable block is corrected, so that the movable block can be twisted at a certain angle during the docking process, thereby ensuring that the slot inside the movable block can accurately dock with the plug block, thereby improving the stability of the support rod limit; S5. When the surveying and mapping equipment needs to be recycled after use, the staff first holds the column rod with their hands, and then pulls each of the plug blocks one by one, so that the plug blocks can slide in the third slide groove and squeeze the third spring. Then, because the support rod has no fixed limit, the first spring restores it to its initial state, and then the electric telescopic rod is started to restore the movable circular plate to its original position, so that all the rectangular rods are restored to their initial state. This makes it easier for the staff to recycle the surveying and mapping equipment and improves work efficiency.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the opener and closeer, the staff will place the pole at the preset point, and then according to the inclination state of the counterweight block and the connecting rope when hanging, the staff can adjust the position of the pole, so as to adjust the pole to a vertical state with the ground. When the pole is adjusted to a vertical state, the electric telescopic rod can be started, and the output end of the electric telescopic rod drives the moving circular plate to slide toward the ground on the outer wall of the pole. A through hole with a diameter larger than the spur rack is opened on the top of the moving circular plate. During the downward movement of the moving circular plate, the spur rack contacts the spur gear, thereby driving the spur gear to drive the worm to rotate, thereby driving the worm gear to drive the rectangular rod to rotate. When the spur gear is separated from the spur rack, the rectangular rod rotates 30 degrees, so that the three rectangular rods are in an unfolded state to support downward, without the need for manual operation by the staff, thereby improving the overall practicality of the device; 2. By setting an adaptive mechanism, when the ground is uneven, the rectangular rod moves downward to support and drives the support rod to move synchronously. When the supported ground is uneven, the support rod encounters resistance during the descent process and squeezes the first spring to slide relative to the rectangular rod, so that the support rod can perform adaptive support according to the flatness of the ground, so that the support rod can fit the ground more closely, thereby enhancing the support and fixation of the equipment on the uneven ground, without the need for frequent adjustments by the staff, thereby improving the overall practicality of the device; 3. By setting a locking assembly, when the support rod moves inside the rectangular rod, the fixed block is driven to move at the same time. Since the top of the plug block and the bottom of the movable block are provided with inclined surfaces, the fixed block contacts the movable block through the inclined surface of the top of the plug block during the movement. Under the action of the inclined surface, the movable block is pushed to drive the slider to move inside the second slide groove. When the plug block is separated from the movable block, the movable block is reset under the action of the second spring to support the bottom of the plug block, thereby limiting the position of the support rod after contraction, thereby ensuring the stability and position accuracy of the support rod after contraction, thereby ensuring the stability of the adaptive support of the device; 4. By setting a fine-tuning unit, when the support rod stops moving relatively, the end of the plug block is located on one side of the movable block, and the slot on the inner side of the movable block is docked with the plug block, the slot moves toward the plug block under the push of the second spring, and when the slot and the plug block are completely aligned, the plug block is supported by the slot on the inner side of the movable block. When there is a deviation between the slot and the plug block, the slot moves toward the plug block while the slot and the buffer inclined surface form an outer eight-shaped shape, and the plug block contacts it during the docking process. Under the action of the inclined surface, the position of the movable block is corrected, so that the movable block can be twisted at a certain angle during the docking process, thereby ensuring that the slot on the inner side of the movable block can accurately dock with the plug block, thereby improving the stability of the support rod limit.

Example

[0021] The locking assembly is located on the outer wall of the rectangular rod 8 and is used to cooperate with the adaptive mechanism to form a stable support. The locking assembly includes a fixed block 13 fixedly connected to the side wall of the support rod 9. The side wall of the fixed block 13 is provided with a third slide groove 19. The inside of the third slide groove 19 is slidably connected with an insert block 14. A third spring 24 is installed between the insert block 14 and the third slide groove 19. The side wall of the rectangular rod 8 is provided with a plurality of second slide grooves 12. The plurality of second slide grooves 12 are equidistantly distributed on one side of the rectangular rod 8. A slider 20 is slidably connected inside the plurality of second slide grooves 12. A second spring 16 is installed between the second slide groove 12 and the slider 20. A movable block 15 is provided on one side of the slider 20. The spacing between each two movable blocks 15 is the same as that between the insert block 14 and the third slide groove 19. The thickness of the block 14 matches, and a fine-tuning unit for adjusting the position of the movable block 15 is provided between the slider 20 and the movable block 15. The fine-tuning unit includes a second fixed seat 21 fixedly connected to the inner side of the slider 20, and the two sides of the movable block 15 are fixedly connected with a second shaft rod 22, and one end of the second shaft rod 22 penetrates to the outside of the second fixed seat 21 and is rotatably connected to the second fixed seat 21, and one side of the second shaft rod 22 is fixedly connected to two fixed plates 25, and one side of the second fixed seat 21 is located in the middle of the two fixed plates 25 and is fixedly connected to a limiting rod 26, and a slot 23 is provided on the inner side of the movable block 15, and a buffer slope 33 is provided at the bottom of the slot 23, and the slot 23 and the buffer slope 33 form an outer eight-character shape; When the support rod 9 moves inside the rectangular rod 8, it drives the fixed block 13 to move. Because the top of the plug block 14 and the bottom of the movable block 15 are provided with inclined surfaces, the fixed block 13 contacts the movable block 15 through the inclined surface at the top of the plug block 14 during the movement. Under the action of the inclined surface, the movable block 15 is pushed to drive the slider 20 to move inside the second slide groove 12. When the plug block 14 is separated from the movable block 15, the movable block 15 is reset under the action of the second spring 16 to support the bottom of the plug block 14, thereby limiting the position of the support rod 9 after contraction, thereby ensuring the stability and position accuracy of the support rod 9 after contraction, thereby ensuring the stability of the adaptive support of the device; The elastic coefficient of the third spring 24 is greater than the elastic coefficient of the second spring 16. When the support rod 9 stops moving relatively, the end of the plug block 14 is located on one side of the movable block 15, and the slot 23 inside the movable block 15 is docked with the plug block 14. Under the push of the second spring 16, the slot 23 moves toward the plug block 14. When the slot 23 is completely aligned with the plug block 14, the plug block 14 is limited by the slot 23 inside the movable block 15. Support. When there is a deviation between the slot 23 and the plug block 14, the slot 23 moves toward the plug block 14 while the slot 23 and the buffer inclined surface 33 form an outer eight-character shape. During the docking process, the plug block 14 contacts it. Under the action of the inclined surface, the position of the movable block 15 is corrected, so that the movable block 15 can be twisted at a certain angle during the docking process, thereby ensuring that the slot 23 inside the movable block 15 can accurately dock with the plug block 14, thereby improving the stability of the support rod 9 limit. When the surveying and mapping equipment needs to be recycled after use, the staff first holds the column 1 with their hands, and then pulls each plug block 14 one by one, so that the plug block 14 can slide in the third slide groove 19 and squeeze the third spring 24. Then, because the support rod 9 has no fixed limit, the first spring 11 restores it to its initial state, and then the electric telescopic rod 5 is started to restore the movable circular plate 6 to its original position, so that all the rectangular rods 8 are restored to their initial state, which makes it convenient for the staff to recycle the surveying and mapping equipment and improves work efficiency.

[0022] In combination with the above-mentioned engineering surveying and mapping equipment, an engineering surveying and mapping method is provided below, which specifically includes the following steps: S1. First, the staff places the pole 1 at a preset point, and then according to the inclination state of the counterweight block 4 and the connecting rope 17 when hanging, the staff can adjust the position of the pole 1, so as to adjust the pole 1 to a state perpendicular to the ground. When the pole 1 is adjusted to a vertical state, the electric telescopic rod 5 can be started, and the output end of the electric telescopic rod 5 drives the moving circular plate 6 to slide on the outer wall of the pole 1 toward the ground. A through hole with a diameter larger than the spur rack 30 is provided on the top of the moving circular plate 6. During the downward movement of the moving circular plate 6, the spur rack 30 contacts the spur gear 29, thereby driving the spur gear 29 to drive the worm 28 to rotate, thereby driving the worm gear 31 to drive the rectangular rod 8 to rotate. When the spur gear 29 is separated from the spur rack 30, the rectangular rod 8 rotates thirty degrees, so that the three rectangular rods 8 are supported downward in an unfolded state, without the need for manual operation by the staff, thereby improving the overall practicality of the device; S2. When the ground is uneven, the rectangular rod 8 moves downward to support and drives the support rod 9 to move synchronously. When the supported ground is uneven, the support rod 9 encounters resistance during the descent process and squeezes the first spring 11 to slide relative to the rectangular rod 8, so that the support rod 9 can adaptively support according to the flatness of the ground, so that the support rod 9 can fit the ground more closely, thereby enhancing the device on the uneven ground to better support and fix the device, without the need for frequent adjustments by the staff, thereby improving the overall practicality of the device; S3. When the support rod 9 moves inside the rectangular rod 8, it drives the fixed block 13 to move. Because the top of the plug block 14 and the bottom of the movable block 15 are provided with inclined surfaces, the fixed block 13 contacts the movable block 15 through the inclined surface at the top of the plug block 14 during the movement. Under the action of the inclined surface, the movable block 15 is pushed to drive the slider 20 to move inside the second slide groove 12. When the plug block 14 is separated from the movable block 15, the movable block 15 is reset under the action of the second spring 16 to support the bottom of the plug block 14, thereby limiting the position of the support rod 9 after contraction, thereby ensuring the stability and position accuracy of the support rod 9 after contraction, thereby ensuring the stability of the adaptive support of the device; S4, the elastic coefficient of the third spring 24 is greater than the elastic coefficient of the second spring 16. When the support rod 9 stops moving relatively, the end of the plug block 14 is located on one side of the movable block 15, and the slot 23 inside the movable block 15 is docked with the plug block 14. Under the push of the second spring 16, the slot 23 moves toward the plug block 14. When the slot 23 is completely aligned with the plug block 14, the plug block 14 is supported by the slot 23 inside the movable block 15. When there is a deviation between the slot 23 and the plug block 14, the slot 23 moves toward the plug block 14 while the slot 23 and the buffer inclined surface 33 form an outer eight-character shape. During the docking process, the plug block 14 contacts it. Under the action of the inclined surface, the position of the movable block 15 is corrected, so that the movable block 15 can be twisted at a certain angle during the docking process, thereby ensuring that the slot 23 inside the movable block 15 can accurately dock with the plug block 14, thereby improving the stability of the support rod 9 limit. S5. When the surveying and mapping equipment needs to be recycled after use, the staff first holds the column 1 with their hands, and then pulls each plug block 14 one by one, so that the plug block 14 can slide in the third slide groove 19 and squeeze the third spring 24. Then, because the support rod 9 has no fixed limit, the first spring 11 restores it to its initial state. Then, the electric telescopic rod 5 is started to restore the movable circular plate 6 to its original position, so that all the rectangular rods 8 are restored to their initial state. This makes it convenient for the staff to recycle the surveying and mapping equipment and improves work efficiency.

9. An engineering surveying and mapping method, characterized in that: An engineering surveying and mapping device according to any one of claims 1 to 8 is used, comprising the following steps: S1. First, a staff member places the column (1) at a preset point. Then, according to the tilt state of the counterweight (4) and the connecting rope (17) when the column (1) is suspended, the staff member can adjust the position of the column (1) to adjust the column (1) to a vertical state with respect to the ground. When the column (1) is adjusted to a vertical state, the electric telescopic rod (5) can be started. The output end of the electric telescopic rod (5) drives the movable circular plate (6) to slide on the outer wall of the column (1) toward the ground. The top of the movable circular plate (6) is provided with a diameter larger than that of the column (1). The movable circular plate (6) is provided with a through hole of the spur rack (30), and in the process of moving downward, the spur rack (30) contacts the spur gear (29), thereby driving the spur gear (29) to drive the worm (28) to rotate, thereby driving the worm wheel (31) to drive the rectangular rod (8) to rotate. When the spur gear (29) is separated from the spur rack (30), the rectangular rod (8) rotates 30 degrees, so that the three rectangular rods (8) are supported downward in an unfolded state, without the need for manual operation by staff, thereby improving the overall practicality of the device; S2. When the ground is uneven, the rectangular rod (8) drives the support rod (9) to move synchronously in the process of moving downward to provide support. When the supported ground is uneven, the support rod (9) encounters resistance in the process of descending and squeezes the first spring (11) to slide relative to the rectangular rod (8), so that the support rod (9) can perform adaptive support according to the flatness of the ground, so that the support rod (9) can fit the ground more closely, thereby enhancing the support and fixation of the device on the uneven ground, without the need for frequent adjustments by the staff, thereby improving the overall practicality of the device; S3, when the support rod (9) moves inside the rectangular rod (8), it drives the fixed block (13) to move, because the top of the plug block (14) and the bottom of the movable block (15) are provided with inclined surfaces, so that the fixed block (13) contacts the movable block (15) through the inclined surface of the top of the plug block (14) during the movement. Under the action of the inclined surface, the movable block (15) is pushed to drive the slider (20) to move inside the second slide groove (12). When the plug block (14) and the movable block (15) are separated, the movable block (15) is reset under the action of the second spring (16) to support the bottom of the plug block (14), thereby limiting the position of the support rod (9) after contraction, thereby ensuring the stability and position accuracy of the support rod (9) after contraction, thereby ensuring the stability of the adaptive support of the device; S4, the elastic coefficient of the third spring (24) is greater than the elastic coefficient of the second spring (16), when the support rod (9) stops moving relative to each other, the end of the plug block (14) is located on one side of the movable block (15), and the slot (23) inside the movable block (15) is docked with the plug block (14), and under the push of the second spring (16), the slot (23) moves toward the plug block (14), and when the slot (23) is completely aligned with the plug block (14), the slot (23) inside the movable block (15) forms a limiting support for the plug block (14), and when the When there is a deviation between the slot (23) and the plug block (14), the slot (23) moves toward the plug block (14) and, during the docking process, the plug block (14) contacts the slot (23) and the buffer inclined surface (33) to form an outward-facing "X" shape. Under the action of the inclined surface, the position of the movable block (15) is corrected, so that the movable block (15) can be twisted at a certain angle during the docking process, thereby ensuring that the slot (23) inside the movable block (15) can accurately dock with the plug block (14), thereby improving the stability of the support rod (9) in limiting the position. S5. When the surveying and mapping equipment needs to be recycled after use, the staff first supports the column rod (1) with their hands, and then pulls each of the plug blocks (14) one by one, so that the plug blocks (14) can slide in the third slide groove (19) and squeeze the third spring (24). Then, because the support rod (9) has no fixed limit, the first spring (11) restores it to its initial state. Then, the electric telescopic rod (5) is started to restore the movable circular plate (6) to its original position, so that all the rectangular rods (8) are restored to their initial state. This makes it easier for the staff to recycle the surveying and mapping equipment and improves work efficiency.
