Description
Technical Field
[0001] This invention relates to the field of land surveying technology, and in particular to a land surveying device and system with fixed-point marking. Background Technology
[0002] Land surveying devices with fixed-point marking are indispensable tools in land surveying and engineering construction. Their core function is to provide a reliable spatial positioning benchmark for subsequent work through precise fixed-point marking and measurement. Among them, the existing authorized patent with publication number CN222689177U discloses a fixed-point marking device for land surveying, which includes a marking box and a marking mechanism. The bottom of the marking box is equipped with a first traveling wheel, and the front left side of the bottom of the marking box is equipped with a second traveling wheel. An installation rod is rotatably installed on the inner wall of the marking box, and a dispersion plate is fixedly installed on the front of the installation rod. The surface of the dispersion plate has dispersion holes. A placement box is installed at the bottom of the inner wall of the marking box, a spring is fixedly installed at the bottom of the inner wall of the placement box, a support plate is fixedly installed at the top of the spring, and a blocking block is fixedly installed at the top of the inner wall of the placement box. The bottom of the blocking block is inclined. This utility model, by setting up a dispersion plate, dispersion holes, and a marking mechanism, enables the marking mechanism to place the marking rod for marking, so that the marking rod can be pushed into the dispersion plate through the dispersion holes and slide out of the dispersion holes and fall to the ground, thus facilitating the insertion of the marking rod into the ground for marking. As can be seen from the existing land surveying devices mentioned above, the existing surveying devices are mainly composed of a mobile carrier and a corresponding marking mechanism. At the same time, the corresponding devices are also equipped with a corresponding positioning module to achieve rapid location determination. In order to determine the marked position more quickly and accurately when conducting surveying and positioning, the existing surveying devices mostly use modern positioning technologies such as GPS (GNSS) positioning measurement, RTK positioning measurement, and inertial navigation measurement for location determination and measurement.
[0003] When using modern positioning mechanisms for positioning measurements, most modules require the reception of satellite signals. However, electromagnetic waves are affected by interference from the ionosphere and troposphere as they propagate through the atmosphere. In large cities or mountainous areas, tall buildings and trees can also affect signal propagation, leading to positioning errors. Furthermore, when the number of satellites in the corresponding area is small, the positioning information may not be stable enough. Therefore, it is often necessary to use some mechanical equipment, such as total stations, for auxiliary positioning measurements. However, using specialized equipment not only increases the amount of equipment carried but also further increases the actual workload of the operators. This makes the overall operation of land measurement for positioning and marking quite complex and cumbersome, greatly affecting the overall measurement efficiency. Summary of the Invention
[0004] The purpose of this invention is to provide a land surveying device and system for fixed-point marking.

[0036] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.
[0037] Please see Figures 1 to 14This invention provides a land surveying device and system for fixed-point marking: It includes a push base 101, an operation box 102, a marking rod 103, and a measuring component.

The system comprises a frame 108, a sliding column 109, a rotating latch 110, a rolling column 111, a flip lock frame 112, a sliding adsorption frame 113, and an electromagnetic adsorption device 114. The resistance mechanism includes a lace wheel 403, a connecting frame 404, a blocking slide 405, and an ejector spring 406. The winding mechanism includes a transfer frame 407, a rotating disk 408, a guide slot frame 409, a rotating ring 410, a fixed bracket 411, a single-tooth slide 412, an extrusion spring 413, a connecting gear 414, a driving gear ring 415, a driving gear 416, and a driving motor 417. This solution addresses the issue of most positioning measurements using modern positioning mechanisms being difficult. Each module requires satellite signal reception. However, electromagnetic waves are affected by interference from the ionosphere and troposphere as they propagate through the atmosphere. In large cities or mountainous areas, tall buildings and trees can also affect signal propagation, leading to positioning errors. Furthermore, when the number of satellites in the corresponding area is small, the positioning information may not be stable enough. Therefore, it is often necessary to use some mechanical equipment, such as a total station, for auxiliary positioning measurements. However, using specialized equipment for measurement not only increases the amount of equipment carried but also further increases the actual workload of the operators. This makes the overall operation of land measurement for positioning and marking quite complex and cumbersome, greatly affecting the overall measurement efficiency.
[0038] Furthermore, the operation box 102 is slidably mounted on the push base 101. The bottom of the marking rod 103 is provided with a tapered drill bit. The measuring mark 104 cooperates with the marking rod 103 inserted into the corresponding positioning point via a locking mechanism. The locking mechanism is fixed to one end of the measuring mark 104, used to complete the connection of the corresponding end of the measuring mark 104. The initial guide frame 105 is fixedly mounted inside the operation box 102, used to guide the measuring mark 104 entering the operation box 102. The angle observation instrument 106 is fixedly installed on the side of the operation box 102 near the initial guide frame 105, and is used to monitor the offset angle of the measurement mark 104 guided by the initial guide frame 105. The prompting device 107 is electrically connected to the angle observation instrument 106 and is installed on the operation box 102. The control line component is connected to the measurement mark 104 and is used to adjust the measurement mark 104. The marking component is connected to the operation box 102 and is used to complete the fixed-point insertion of the marking rod 103.
[0039] Specifically, the push base 101 is equipped with four wheels and a push handle to facilitate the operator to push the entire device. The operation box 102 is slidably mounted on the push base 101 by cooperating with the sliding grooves on both sides of the push base 101, and the operation box 102 can slide left and right on the push base 101.
[0040] The bottom of the marker rod 103 is provided with a conical drill bit, which allows the marker rod 103 to be inserted more easily and stably. The measuring mark 104 is used to mechanically measure the position between the marker points. The measuring mark 104 is provided with sensing marks at intervals, so that the total length of the measuring mark 104 can be judged by the corresponding mechanism, thereby determining the specific distance between the two marker points.
[0041] The locking mechanism is located at the end of the measuring mark 104, and the measuring mark 104 can cooperate with the mark insertion rod 103 after installation through the locking mechanism.
[0042] The locking mechanism includes a sleeve bracket 108, a sliding column 109, a rotating buckle 110, a rolling column 111, a flip-lock frame 112, a sliding adsorption frame 113, and an electromagnetic adsorption device 114. The sleeve bracket 108 is fixed to the end of the measuring mark 104; the sliding column 109 is rotatably mounted on the sleeve bracket 108; the rotating buckle 110 is rotatably mounted on the sleeve bracket 108; the rolling column 111 is rotatably mounted on the rotating buckle 110; the flip-lock frame 112 is rotatably mounted on the sleeve bracket 108; the sliding adsorption frame 113 is slidably mounted on the side of the sleeve bracket 108 near the flip-lock frame 112; and the electromagnetic adsorption device 114 is mounted on the side of the sleeve bracket 108 near the sliding adsorption frame 113.
[0043] The sleeve bracket 108 is adapted to the sleeve area set at the upper end of the marking rod 103. The sleeve bracket 108 is provided with corresponding sliding posts 109 on both sides so that the sleeve bracket 108 can move upward normally while maintaining the sleeve relationship with the marking rod 103. The side of the operation box 102 is provided with a corresponding storage slot, which can accommodate multiple marking rods 103, making it more convenient for users to mark multiple points.
[0044] The sleeve bracket 108 has an opening on one side to facilitate the user's installation of the sleeve bracket 108. The rotating buckle 110 is rotatably installed at the opening of the sleeve bracket 108. The rotating buckle 110 is rotatably provided with the rolling column 111. The rolling column 111 and the sliding column 109 have the same function, which is to ensure that the entire sleeve structure can slide normally up and down on the rotating buckle 110.
[0045] The sleeve bracket 108 is provided with a corresponding flip-lock frame 112 at a position that cooperates with the side of the rotating buckle 110. The flip-lock frame 112 is limited by the provided sliding suction frame 113. The top of the sliding suction frame 113 is provided with a corresponding suction plate. The electromagnetic adsorption device 114 has a corresponding electromagnet built in. When the electromagnetic adsorption device 114 is powered on, the sliding suction frame 113 will be attracted by the electromagnetic adsorption device 114 and move upward. When the electromagnetic adsorption device 114 is de-powered, the sliding suction frame 113 will slide down under its own weight. The flip-lock frame 112 is "L" shaped. The sleeve bracket 108 is positioned to engage with the flip-lock frame 112. Friction sleeves are provided at both ends of the connecting central shaft. When the user rotates the rotating lever 110 to engage with the flip lock frame 112, the flip lock frame 112 can rotate under the action of the rotating lever 110. After the flip lock frame 112 rotates, the sliding suction frame 113 will slide down under its own weight, thereby limiting the flip lock frame 112. In this way, one end of the measuring mark 104 can be sleeved on the corresponding marking rod 103, so that the user can pull the control line component provided with the push base 101 to lay out the measuring mark 104. Finally, the distance measurement and positioning between the marked points is completed according to the length of the laid-out measuring mark 104.
[0046] After the measuring mark 104 is laid out, to prevent the measuring mark 104 from sagging and affecting the final measurement accuracy, it needs to be tightened. At this time, the sliding column 109 on the sleeve bracket 108 and the rolling column 111 on the rotating buckle 110 can drive the corresponding sleeve mechanism to slide on the corresponding mark insertion rod 103, so as to achieve horizontal alignment of the two measurement points of the measuring mark 104. After the measurement is completed, the user can remotely control the electromagnetic adsorption device 114 to be powered on, so that the sliding adsorption frame 113 moves upward. In this way, the flip lock frame 112 will lose the limit of the sliding adsorption frame 113, thereby directly detaching the sleeve bracket 108 from the corresponding mark insertion rod 103. Then, the measuring mark 104 is retracted, allowing the operator to... Installation and measurement do not require assistance from multiple people; the measurement markings 104 can be applied and removed independently. After the rotating lever 110 is removed, the flip-lock frame 112 will rotate due to the outward movement of the rotating lever 110. At this time, the side brackets of the flip-lock frame 112 will block the sliding suction frame 113. Since the flip-lock frame 112 will not rotate unless subjected to strong external force due to the influence of the friction sleeves on both sides, the sliding suction frame 113 will not immediately move down after the electromagnetic adsorption device 114 is powered off. Only when the user installs the rotating lever 110 again, and the rotating lever 110 drives the flip-lock frame 112 to rotate, will the sliding suction frame 113 move down to limit the flip-lock frame 112 accordingly. This also makes it more convenient for the user to install the rotating lever 110 in the future.
[0047] In actual operation, the user can first install the marker rod 103 at the first determined mark point, and then use the locking mechanism to fit the corresponding side of the measuring line 104 onto the first marker rod 103. The user then moves the entire device by pushing the push base 101. When the measuring line 104 enters the operating box 102, it is guided by the initial guide frame 105. If the measuring line 104 deviates, it will bend on the initial guide frame 105. The angle observation instrument 106 can then observe the rotation angle of the measuring line 104 by taking pictures and analyzing the actual situation of the measuring line 104 in the pictures. If a large deviation in the rotation angle occurs, a voice prompt will be given through the prompting device 107, allowing the operator to adjust the movement of the push base 101 in a timely manner. The system ensures the accuracy of subsequent marker point locations. Once the subsequent marker point positioning is completed, the new marker rod 103 can be installed using the marking component inside the operation box 102. Simultaneously, the measuring line 104 can be retrieved using the control component and locking mechanism to complete the subsequent positioning measurement and marking of the positioning points. The entire process primarily relies on the rewinding length of the measuring line 104 to determine the distance, thus eliminating the need for a positioning signal. This system assists operators in quickly measuring, positioning, and marking marker points when the positioning device is malfunctioning or ineffective. It enables rapid measurement and positioning between marker points even when the positioning information is unstable, eliminating the need for cumbersome operations and adjustments using additional equipment. This makes actual land surveying and positioning more convenient and efficient, significantly increasing land surveying and positioning efficiency.
[0048] Furthermore, the mounting box 201 is fixedly installed inside the operating box 102; a plurality of guide wheels 202 are rotatably installed inside the operating box 102 for guiding the measuring mark 104 entering the operating box 102; the line distance sensing device 203 is fixedly installed inside the mounting box 201; the winding and unwinding component is connected to the mounting box 201 for unwinding and winding the measuring mark 104; and the level judgment component is connected to the mounting box 201 for judging the winding measurement status of the measuring mark 104.
[0049] In this embodiment, when in use, the mounting box 201 is provided with multiple guide rollers 202. The measuring mark 104 is guided and transmitted through the multiple guide rollers 202. The line distance sensing device 203 is located at the inlet port of the mounting box 201. The mounting box 201 is provided with a corresponding soft brush sleeve at the inlet opening for the line to be introduced, so as to clean the line entering the mounting box 201 and avoid the line surface from being covered with too many impurities, which would prevent normal shooting and scanning in the future.
[0050] The line distance sensing device 203 continuously detects and analyzes the measurement mark 104 at one end to determine the winding length of the measurement mark 104, thereby analyzing and determining the actual distance between the two positioning points. Since the measurement mark 104 is equipped with sensing marks at intervals, the judgment can be quickly made by using the corresponding sensing marks. The horizontal judgment component can judge the tension state of the measurement mark 104. Only when the measurement mark 104 is fully tensioned can the distance information fed back by the measurement mark 104 be more accurate, thus avoiding large measurement errors. The tension state of the measurement mark 104 can be maintained and adjusted by the winding and unwinding component. The winding and unwinding component mainly completes the unwinding and winding of the measurement mark 104. By using the winding of the measurement mark 104 in conjunction with the horizontal judgment component, the measurement mark 104 can be kept in a stable tension state, thereby realizing rapid distance measurement and marking between the two positioning points.
[0051] Furthermore, the loading bracket 301 is connected to the operation box 102 via the adjustment component; the lowering bracket 302 is slidably mounted on the loading bracket 301; the adjustment component is connected to the operation box 102 and is used to adjust the mating position of the loading bracket 301; the insertion component is connected to the loading bracket 301 and is used to complete the fixed-point insertion of the marking rod 103; the pull-out component is located below the loading bracket 301 and is used to pull the measuring mark 104 in the lowering area of the marking rod 103.
[0052] In this embodiment, during use, the loading bracket 301 can move within the control box along the measuring direction of the measuring mark 104 via the adjustable component, facilitating subsequent fine adjustments to the marker points. Both the loading bracket 301 and the lowering frame 302 are provided with through holes for the marker insertion rod 103 to engage. A corresponding cylindrical platform is also provided below the lowering frame 302 to engage with the bottom holding frame of the loading bracket 301, ensuring the stability of the lowering frame 302 during its downward movement. The marker insertion rod 103 passes directly through the lowering frame 302 by engaging with the internal insertion slot, allowing subsequent insertion of the rod at a designated position via the provided insertion component.
[0053] The pulling component is located directly below the loading bracket 301 so that when the marking rod 103 is inserted, the measuring mark 104 within the corresponding range can be guided and pulled out, so as to avoid the measuring mark 104 interfering with the insertion of the marking rod 103.
[0054] Furthermore, the outer cylinder 401 is fixedly installed inside the mounting box 201; the measuring mark 104 is wound on the winding drum 402, and the winding drum 402 is rotatably installed inside the outer cylinder 401; the resistance mechanism is connected to the outer cylinder 401 and is used to limit the rotation of the winding drum 402 to a certain extent; the winding mechanism is connected to the winding drum 402 and is used to drive the winding drum 402 to rotate to complete the winding of the measuring mark 104.
[0055] Furthermore, the resistance mechanism includes a lace wheel 403, a connecting frame 404, a blocking slide 405, and an ejector spring 406. The lace wheel 403 is fixedly installed on the outside of the winding drum 402; the connecting frame 404 is fixedly installed on the side of the outer drum 401 near the lace wheel 403; the blocking slide 405 is slidably installed on the connecting frame 404; and the two sides of the ejector spring 406 are respectively connected to the blocking slide 405 and the connecting frame 404.
[0056] Furthermore, the winding mechanism includes an adapter frame 407, a rotating disk 408, a groove guide frame 409, a rotating ring 410, a fixed bracket 411, a single-tooth slide 412, an extrusion spring 413, a connecting gear 414, a driving gear ring 415, a driving gear 416, and a driving motor 417. The adapter frame 407 is fixedly installed on the side of the outer cylinder 401 away from the lace wheel 403; the rotating disk 408 is rotatably installed on the adapter frame 407; the groove guide frame 409 is fixedly installed on one side of the rotating disk 408; the rotating ring 410 is rotatably installed on the side of the outer cylinder 401 close to the groove guide frame 409; and the fixed bracket 411 is fixedly installed on the... The rotating ring 410 is located near the side of the guide rail 409; the single-tooth slide 412 is slidably mounted on one side of the fixed bracket 411; the two sides of the extrusion spring 413 are respectively connected to the single-tooth slide 412 and the fixed bracket 411; the connecting gear 414 is fixedly mounted on the side of the winding drum 402 away from the lace wheel 403; the driving gear ring 415 is fixedly mounted on the guide rail 409; the driving gear 416 meshes with the driving gear ring 415 and is rotatably mounted on the outer cylinder 401; the output shaft of the driving motor 417 is connected to the driving gear 416, and the driving motor 417 is fixedly mounted on the outer cylinder 401.
[0057] In this embodiment, the outer cylinder 401 is fixed inside the mounting box 201, and the winding drum 402 is rotatably installed inside the outer cylinder 401. The measuring mark 104 is guided into the outer cylinder 401 by multiple guide wheels 202 inside the mounting box 201, and finally wound by the winding drum 402.
[0058] The lace wheel 403 and the connecting gear 414 are fixed on both sides of the central shaft on which the winding drum 402 and the outer drum 401 rotate. The lace wheel 403 has multiple arc-shaped platforms on its outer side, and a corresponding blocking slide 405 is provided on the outer side of the lace wheel 403. The blocking slide 405 abuts against the outer arc-shaped platforms of the lace wheel 403 under the action of the ejector spring 406 and the connecting frame 404. When the lace wheel 403 rotates with the winding drum 402, the lace wheel 403 will continuously squeeze the blocking slide 405 to move, thereby increasing the rotational resistance of the winding drum 402. This prevents the winding drum 402 from rotating too fast when the user pulls the push base 101 to move it, and also prevents the winding drum 402 from rotating on its own after the push base 101 stops.
[0059] The connecting gear 414 engages with the single-tooth slide 412 on the fixed bracket 411. The single-tooth slide 412 is provided with a toothed platform that engages with the tooth groove of the connecting gear 414. The single-tooth slide 412 can rotate on the corresponding side of the outer cylinder 401 via the rotating ring 410 provided at the bottom of the fixed bracket 411. A corresponding protruding frustum is provided on the outer side of the single-tooth slide 412. The guide groove of the guide frame 409 has different widths at both ends to allow the protruding frustum to pass through the guide groove. The engagement of the two ends at different positions drives the single-tooth slide 412 to move. The guide groove provided on the guide frame 409 engages with the protruding frustum on the outer side of the single-tooth slide 412. The guide frame 409 rotates with the adapter frame 407 via the rotating disk 408. The adapter frame 407 is fixed on the outer cylinder 401. At the same time, the guide frame 409 is also provided with a corresponding drive gear ring 415. The drive gear ring 415 is driven by the drive gear 416 and the drive motor 417.
[0060] When the winding drum 402 is in normal unwinding mode, the single-tooth slide 412 will be in a retracted state under the action of the extrusion spring 413. At this time, the connecting gear 414 cannot engage with the toothed platform of the single-tooth slide 412, and the winding drum 402 can rotate freely. When the winding drum 402 is in winding mode, the drive motor 417 will work with the drive gear 416 to drive the drive gear ring 415 and the guide slot frame 409 to rotate. Through the rotation of the guide slot frame 409, the protruding truncated cone on the outer side of the single-tooth slide 412 will slide due to its engagement with the guide slot of the guide slot frame 409. As the single-tooth slide 412 slides continuously, the extrusion spring 413 will continuously press it. After the narrow end of the guide groove on the guide frame 409 engages with the protruding truncated cone on the side of the single-tooth slide 412, the single-tooth slide 412 will extend completely, thereby completing the engagement between the single-tooth slide 412 and the corresponding tooth groove of the connecting gear 414. When the guide frame 409 continues to rotate, the single-tooth slide 412 will drive the fixed bracket 411 and the rotating ring 410 to rotate under the drive of the guide frame 409, and at the same time, it will drive the connecting gear 414 accordingly. In this way, by driving the connecting gear 414 to rotate, the corresponding drive of the winding drum 402 can be completed.
[0061] After the wire is wound up, the guide slot frame 409 only needs to rotate back by the corresponding angle so that the wide end of the guide slot on the guide slot frame 409 engages with the protruding truncated cone on the outer side of the single tooth slide 412. In this way, the single tooth slide 412 will retract again under the action of the extrusion spring 413, so that the connecting gear 414 and the winding drum 402 can rotate freely again to realize the subsequent wire release of the measuring mark 104.
[0062] Furthermore, the sliding bracket 501 is fixedly installed inside the mounting box 201; the sliding block 502 is slidably installed on the sliding bracket 501; the pressure wheel 503 is rotatably installed on the sliding block 502; and the position sensor 504 is fixedly installed on the side of the mounting box 201 near the sliding block 502 for sensing the upper limit position of the sliding block 502.
[0063] In use, the sliding block 502 slides up and down by cooperating with the sliding brackets 501 on both sides. The sliding block 502 is provided with a corresponding pressure wheel 503 in the middle. The groove of the pressure wheel 503 cooperates with the measuring mark 104. The two position sensors 504 are arranged above the two sides of the sliding block 502.
[0064] When the measuring mark 104 is in a relaxed state, the pressure roller 503 on the sliding block 502 will press down on the measuring mark 104 due to its own weight. At this time, the inductive switch at the end of the position sensor 504 will not cooperate with the top of the sliding block 502. When the measuring mark 104 is in a taut state, the pressure roller 503 will drive the sliding block 502 to move upward, so that the top of the sliding block 502 contacts the inductive switch below the position sensor 504. In this way, the specific state of the sliding block 502 can be used to determine whether the measuring mark 104 is in a taut state.
[0065] Furthermore, the adjusting bracket 601 is slidably installed inside the operating box 102; the output end of the adjusting cylinder 602 is connected to the adjusting bracket 601, and the adjusting cylinder 602 is fixedly installed inside the operating box 102; the lifting frame 603 is fixedly connected to the loading bracket 301 and slidably installed on the adjusting bracket 601; the lifting screw drive mechanism 604 is connected to the lifting frame 603 and is used to drive the lifting frame 603.
[0066] In this embodiment, the adjusting bracket 601 is slidably connected to the plate extending from the inside of the operating box 102. Corresponding guide posts are provided on both sides of the adjusting bracket 601 to ensure stable sliding. The output end of the adjusting cylinder 602 is fixed to the adjusting bracket 601 so that the adjusting bracket 601 can be driven by the adjusting cylinder 602. The loading bracket 301 is connected to the adjusting bracket 601 via the lifting frame 603. The lifting frame 603 is slidably mounted on the connecting frame 404 provided on the side of the adjusting bracket 601. The lifting frame 603 is driven by the lifting screw drive mechanism 604, which consists of a corresponding screw and a motor that drives the corresponding screw to rotate. The motor drives the corresponding screw to rotate, thereby completing the driving of the corresponding frame.
[0067] The sliding of the lifting frame 603 on the adjusting bracket 601 allows for adjustment of the fitting height of the loading bracket 301, facilitating subsequent insertion of the marking rod 103 by the user. During normal measurement, the loading bracket 301 is at its highest point, ensuring that the inserted marking rod 103 does not contact the corresponding measuring mark 104, while also increasing the insertion height of the marking rod 103, allowing the user to better assemble the marking rod 103.
[0068] Furthermore, the downward screw drive mechanism 701 is connected to the downward frame 302 and is used to drive the downward frame 302; the through frame 702 is slidably connected to the downward frame 302 and is connected to the marking rod 103 that cooperates with the loading bracket 301; the control screw drive mechanism 703 is connected to the through frame 702 and is used to drive the through frame 702.
[0069] In this embodiment, the downward screw drive mechanism 701 has the same structural principle as the control screw drive mechanism 703 and the lifting screw drive mechanism 604. Simultaneously, a corresponding through-frame 702 is provided on the side of the downward frame 302. The through-frame 702 cooperates with the side support frame of the downward frame 302, allowing it to slide on the side of the downward frame 302. The through-frame 702 has a corresponding through-shaft, and the corresponding position of the marking rod 103 has a through-hole that cooperates with the through-shaft to limit the marking rod 103. This allows the marking rod 103 to be inserted downwards under the drive of the downward frame 302. After insertion, the through-frame 702 can be moved out under the drive of the control screw drive mechanism 703, allowing the marking rod 103 to be directly removed from the through-hole in the downward frame 302 when the downward frame 302 subsequently moves upwards to reset.
[0070] When inserting the marking rod 103, the adjusting cylinder 602 first drives the adjusting bracket 601 to adjust and determine the specific insertion position of the loading bracket 301. Then, the lifting screw drive mechanism 604 drives the lifting frame 603 to move down. Under the drive of the lifting frame 603, the loading bracket 301 will move the assembled marking rod 103 down. Finally, the lowering screw drive mechanism 701 drives the lowering frame 302 and the marking rod 103 to move down, thus completing the rapid insertion of the marking rod 103. The use of multi-stage drive can ensure the compactness of the entire automatic insertion structure.
[0071] Furthermore, the pulling bracket 801 is slidably mounted on the adjusting bracket 601; the pulling screw drive mechanism 802 is connected to the pulling bracket 801 and is used to drive the pulling bracket 801; the lead wheel 803 is rotatably mounted on the pulling bracket 801.
[0072] In this embodiment, the pulling screw drive mechanism 802 and the lifting screw drive mechanism 604 have the same structural principle. The pulling bracket 801 is driven by the pulling screw drive mechanism 802. The two lead wheels 803 on the pulling bracket 801 guide the measuring mark 104 in the designated area. The top surface of the pulling bracket 801 can be used for bottom limiting when the marking rod 103 is installed. The pulling bracket 801 will move with the adjusting bracket 601. Therefore, when the marking rod 103 needs to be lowered and inserted, the measuring mark 104 in the corresponding range can be pulled out, avoiding the measuring mark 104 from affecting the lowering and insertion of the marking rod 103.
[0073] Preferably, the measuring component provided by the present invention further includes an external gear frame 901, an adjusting gear 902, and an adjusting motor 903.
[0074] Furthermore, the external gear frame 901 is fixedly installed on one side of the operation box 102; the adjusting gear 902 meshes with the external gear frame 901 and is rotatably installed on the push base 101; the output shaft of the adjusting motor 903 is connected to the adjusting gear 902, and the adjusting motor 903 is fixedly installed on the push base 101.
[0075] In this embodiment, the external gear frame 901 is fixed to the outside of the operating box 102. The external gear frame 901 cooperates with the adjusting gear 902 rotatably mounted on the side of the push base 101. The adjusting gear 902 is driven by the adjusting motor 903. When the adjusting motor 903 drives the adjusting gear 902 to rotate, the adjusting gear 902 can drive the operating box 102 through cooperation with the external gear frame 901. This allows the user to make corresponding fine adjustments to the left and right positions of the operating box 102 in conjunction with the sensing data of the angle observation instrument 106 when determining the punctuation position.
