Description

Technical Field

[0001] The present invention mainly relates to the technical field of on-site survey, and in particular to an on-site survey method for urban planning. Background Art

[0002] The on-site survey method of urban planning is one of the important links in urban planning and design. It is a process of field investigation, mapping, exploration and evaluation of a specific area or site in order to provide basic data and basis for subsequent design, planning and management. During the survey, the equipment needs to be installed on a bracket for positioning.

[0003] A method for topographic survey and positioning for urban planning described in the prior art is to place the main body on the upper surface of the rotating shell, and at the same time, the end of the push button on the upper surface of the rotating shell passes through the circular hole on the lower surface of the main body and moves downward under the gravity of the main body, and the bottom of the main body is fixed and clamped. When the measuring height needs to be adjusted, the rotating button is twisted to drive the rotating rod and transmit the bevel gear four. At the same time, the threads on the two threaded rods cooperate with the connecting arm to drive the lifting shell to slide upward on the inner wall of the fixed shell, and drive the main body to lift the height. When the main body is removed, the torsion spring rebounds due to potential energy, and the gear one drives the gear column to slide upward to the initial position, completing the operation of rebounding to the initial state. The gear column, gear one and screw rod are set up, and the gear column slides downward on the surface of the lifting rod to drive the screw rod on the gear one to rotate, and the bottom of the main body is clamped and fixed.

[0004] Although the above technology can achieve good clamping and fixing of the main body, when the survey is completed and it needs to be disassembled and transported, the clamping block needs to be rotated manually.

After the survey of the area is completed, when it is necessary to separate and transport it to the next survey point, the staff member puts his hand into the handle groove 101 and drives the main body 1 upward through the top plate 1011. At this time, the optical sensor 1012 senses the palm and sends a signal to the first control main board 102. The first control main board 102 starts the two electric telescopic rods 1041, and the push block 1042 moves to push the card rod 403 to move into the cylindrical block 2021, and cooperates with the pull rope 405 to drive the L-shaped downward pressure rod 401 to move upward, lift the base 103, and complete the separation.

[0024] When surveying the site during the process of urban planning, the staff transports the equipment to the site by vehicle, and then places the main body 1 of the surveying instrument on the lifting shell 202 through the base 103, so that the cylindrical block 2021 passes through the perforation. Then the staff rotates the main body 1 and the base 103 according to the survey direction, so that the survey end of the main body 1 is aligned with the direction to be surveyed, and then the staff cooperates with the gravity of the main body 1 and the base 103 to press down, and pushes the driving part of the installation component 4 to move through the lower surface of the base 103. After the lower surface of the base 103 contacts the upper surface of the lifting shell 202, the clamping part of the installation component 4 extends out to fix the base 103, and at the same time cooperates with the inner track tooth 701 of the annular plate 7 to complete the locking; Then the staff surveys and records the site through the main body 1. When the survey is completed and the work needs to be disassembled and transported to another survey point, the staff extends the palm of the hand out of the handle groove 101 and makes the palm contact with the top plate 1011. At this time, the optical sensor 1012 uses infrared rays to illuminate the palm, captures the palm image by detecting the reflected optical fiber, and then sends a signal to the first control main board 102. The optical sensor 1012 is set in the groove, which can also reduce the influence of external light. After receiving the signal, the first control main board 102 sends an electrical signal to start the two electric telescopic rods 1041. The telescopic ends of the two electric telescopic rods 1041 extend and push the push block 1042 to move. The end face of the push block 1042 contacts the end of the clamping member of the installation component 4 and pushes it back into the cavity 2022, while causing the driving member to move upward, lift the base 103 to complete the separation from the lifting shell 202, and finally the staff lifts the main body 1 through the handle groove 101, and the main body 1 drives the base 103 to be lifted through the connecting rod; Therefore, when the present application needs to be disassembled and transported, the main body 1 and the fixed shell 2 can be quickly separated by sensing the palm, without using threads, and the separation is more labor-saving, so that the effect of picking up and going can be achieved; at the same time, the alignment direction of the main body 1 can be adjusted as needed during installation.

[0025] See also Figure 4-7As shown, the mounting assembly 4 includes two symmetrically arranged L-shaped pressing rods 401, and the outer walls on both sides of the cylindrical block 2021 are provided with strip grooves 2023 connected to the cavity 2022. The other ends of the two L-shaped pressing rods 401 pass through the strip grooves 2023 and are located in the cavity 2022. The other ends of the two L-shaped pressing rods 401 are welded with fixing blocks 402, and the bottoms of the two L-shaped pressing rods 401 are symmetrically fixed with supporting springs 407. The top of the cavity 2022 is symmetrically provided with horizontal clamping rods 403. The end faces of the two clamping rods 403 pass through the top of the wall of the cylindrical block 2021. The bottoms of the other ends of the two clamping rods 403 are welded with fixing plates 404. The interior of the cavity 2022 is located between the two fixing plates 40 4, guide wheels 406 are rotatably installed below the two fixing plates 404 and the two fixing blocks 402 are connected by pull ropes 405, the top ends of the two L-shaped pressing rods 401 penetrate the top wall of the lifting shell 202 and contact the lower surface of the base 103, the outer walls of the two pull ropes 405 contact the outer walls of the guide wheels 406, the two side walls of the cavity 2022 are located on the two fixing plates 404 and are provided with movable grooves 6, the two side outer walls of the two fixing plates 404 are welded with side slide plates 4041, each side slide plate 4041 is located in the movable groove 6 and is slidably connected thereto, the ends of the two clamping rods 403 located in the cavity 2022 are provided with grooves 4032, and a tension spring 4033 is fixed between the two grooves 4032; The two clamping rods 403 are fixed with outer teeth 4031 at the bottom of the end surfaces outside the cavity 2022, and the two outer teeth 4031 are meshed with the inner teeth 701. The end surfaces of the two push blocks 1042 match the top of the end surfaces of the clamping rods 403. The two side walls of the two strip grooves 2023 are provided with limiting grooves 5. The two side walls of the two L-shaped downward pressure rods 401 in the strip grooves 2023 are symmetrically welded with limiting rods 501, and each limiting rod 501 is inserted into the corresponding limiting groove 5 and slidably connected thereto.

[0026] When installing the base 103 and the lifting shell 202, the pressed base 103 pushes the L-shaped pressing rod 401 to move downward, and the L-shaped pressing rod 401 moves along the strip groove 2023, and makes the limiting rod 501 slide along the limiting groove 5. At this time, the fixed block 402 moves with the L-shaped pressing rod 401, and the fixed block 402 drives the pull rope 405 to move. The pull rope 405 moves along the guide wheel 406 and drives the fixed plate 404 to move. The fixed plate 404 slides along the moving groove 6 through the side slide plate 4041, and the side slide plate 4041 The clamping rod 403 can be placed in a horizontal state, and the moving fixed plate 404 drives the clamping rod 403 to move synchronously. At this time, the two clamping rods 403 move in opposite directions and stretch the tension spring 4033. When the lower surface of the base 103 contacts the upper surface of the lifting shell 202, the ends of the two clamping rods 403 pass through the cylindrical block 2021 to clamp the upper surface of the base 103. At the same time, the outer track teeth 4031 set at the ends of the clamping rods 403 will also mesh with the inner track teeth 701 of the annular plate 7, further achieving a locking effect. During separation, the clamping rod 403 pushed by the push block 1042 moves, which will cause the fixed plate 404 to drive the pull rope 405 to move, and the pull rope 405 drives the fixed block 402 to move upward along the guide wheel 406, and the fixed block 402 drives the L-shaped downward pressure rod 401 to move upward, so that the end of the L-shaped downward pressure rod 401 extends out of the lifting shell 202 to lift the base 103, completing the separation.

[0027] See also Figure 3 As shown, a lifting shell 202 is movably provided in the fixed shell 2, a support frame 201 is welded at the center of the inner top wall of the fixed shell 2, and a lifting assembly 3 is provided below the support frame 201 and on both sides of the interior of the fixed shell 2, and the lifting assembly 3 is used to adjust the height of the lifting shell 202; The lifting assembly 3 includes a fixed motor 301 arranged at the center of the lower surface of the support frame 201, the output end of the fixed motor 301 is rotatably connected to the inner bottom wall of the fixed shell 2, a large sprocket 302 is fixedly installed on the output end of the fixed motor 301, and the interior of the fixed shell 2 is rotatably installed with screw rods 303 on both sides of the lifting shell 202, and small sprockets 304 are fixedly installed on the outer walls of the bottom ends of the two screw rods 303, and the large sprocket 302 and the two small sprockets 304 are transmission-connected by a transmission chain 305, welding blocks 307 are fixed on both sides of the lower surface of the lifting shell 202, and movable blocks 306 are sleeved on the execution ends of the two screw rods 303, and the two movable blocks 306 are fixedly connected to the welding blocks 307, and the second control mainboard 8 and the battery 801 are respectively installed on both sides of the lower surface of the support frame 201, and the battery 801 and the fixed motor 301 are electrically connected to the second control mainboard 8 through wires.

[0028] After the main body 1 and the lifting shell 202 are installed, when the height adjustment is required during the survey, the staff sends a signal to the second control main board 8 through the external controller. After receiving the signal, the second control main board 8 starts the fixed motor 301, and the output end of the fixed motor 301 drives the large sprocket 302 to rotate. The large sprocket 302 drives the small sprockets 304 on both sides to rotate through the transmission chain 305. The rotation of the two small sprockets 304 drives the threaded screw rod 303 to rotate. The rotation of the two screw rods 303 makes the sleeved movable block 306 move vertically within the limit of the welding block 307 and the lifting shell 202. The movable movable block 306 drives the lifting shell 202 to move through the welding block 307, so that the lifting shell 202 moves out of the fixed shell 2, and the height of the installed main body 1 is adjusted.

[0029] The working principle of the present invention is: When surveying the site during the process of urban planning, the staff transports the equipment to the site by vehicle, places the main body 1 of the surveying instrument on the lifting shell 202 through the base 103, and makes the cylindrical block 2021 pass through the through hole. Then the staff rotates the main body 1 and the base 103 according to the survey direction, so that the surveying end of the main body 1 is aligned with the direction to be surveyed, and then works to press down with the gravity of the main body 1 and the base 103. The pressed base 103 pushes the L-shaped pressing rod 401 to move downward, and the moved L-shaped pressing rod 401 moves along the strip groove 2023, and makes the limiting rod 501 slide along the limiting groove 5. At this time, the fixed block 402 moves with the L-shaped pressing rod 401, and the fixed block 402 drives the pull rope 405 to move. The pull rope 405 moves along the guide wheel 406 and drives the fixed plate 404 to move. The fixed plate 404 slides along the moving groove 6 through the side slide plate 4041, wherein the side slide plate 4041 can make the clamping rod 403 in a horizontal state. The moving fixed plate 404 drives the clamping rod 403 to move synchronously. At this time, the two clamping rods 403 move in opposite directions and stretch the tension spring 4033. When the lower surface of the base 103 contacts the upper surface of the lifting shell 202, the ends of the two clamping rods 403 pass through the cylindrical block 2021 to clamp the upper surface of the base 103. At the same time, the outer track teeth 4031 set at the ends of the clamping rods 403 will also mesh with the inner track teeth 701 of the annular plate 7 to further achieve a locking effect. Then the staff uses the main body 1 to survey and record the site. When the survey is completed and the equipment needs to be disassembled and transported to another survey point, the staff extends the palm of the hand into the handle groove 101 and makes the palm contact with the top plate 1011. At this time, the optical sensor 1012 uses infrared rays to illuminate the palm, captures the palm image by detecting the reflected optical fiber, and then sends a signal to the first control main board 102. After receiving the signal, the first control main board 102 sends an electrical signal to start the two electric telescopic rods 1041. The two electric telescopic rods 1041 are The telescopic end of 41 extends and pushes the push block 1042 to move, and the clamping rod 403 pushed by the push block 1042 moves, which will cause the fixed plate 404 to drive the pull rope 405 to move, and the pull rope 405 drives the fixed block 402 to move up along the guide wheel 406, and the fixed block 402 drives the L-shaped downward pressure rod 401 to move up, so that the end of the L-shaped downward pressure rod 401 extends out of the lifting shell 202 to lift the base 103 to complete the separation. Finally, the staff lifts the main body 1 through the handle slot 101, and the main body 1 drives the base 103 to be lifted through the connecting rod.
