Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping equipment, and in particular to a land surveying and mapping device based on GIS technology. Background Art

[0002] GIS technology is a product of the intersection of multiple disciplines. It is based on geographic space, adopts geographic model analysis methods, and provides multiple spatial and dynamic geographic information in real time. It is a computer technology system that serves geographic research and geographic decision-making. Its basic function is to convert tabular data into geographic graphic display, and then browse, operate and analyze the display results. Its display range can range from intercontinental maps to very detailed block maps, and the real objects include population, sales, transportation routes and other content.

[0003] In the process of land surveying and data collection, a surveying frame is required. In the prior art, when using a surveying frame, the bottom bracket needs to be adjusted according to different terrain requirements. The length of each bracket can be adjusted individually, and all adjustments are manual, which reduces the efficiency of surveying.

[0004] Therefore, a land surveying and mapping device based on GIS technology is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a land surveying and mapping equipment based on GIS technology, which uses a motor to drive the threaded transmission to automatically extend and retract the one-way threaded rod used for support, instead of manual adjustment. At the same time, after the bottom end of the one-way threaded rod is subjected to a certain pressure, it will automatically stop moving, which is very intelligent and can solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A land surveying and mapping equipment based on GIS technology comprises a mounting frame and a surveying and mapping device, wherein a mounting plate is fixedly mounted on the upper side of the mounting frame, the surveying and mapping device is fixedly mounted on the mounting plate, a first fixing frame is fixedly mounted on the bottom wall of the mounting frame, a motor is fixedly mounted in the first fixing frame, an output shaft is rotatably mounted on the upper side of the motor, and the output shaft rotatably penetrates the bottom wall of the mounting frame, a first gear is fixedly mounted on the output shaft, four rotating shafts are fixedly mounted in the mounting frame, a second gear meshing with the first gear is fixedly mounted on the four rotating shafts, fixing tubes are fixedly mounted on the bottom walls of the four second gears, and the fixing tubes movably penetrate the bottom wall of the mounting frame, threaded tubes are inserted into the bottom ends of the four fixing tubes, a one-way threaded rod is threadedly mounted on the bottom end of each of the threaded tubes, a connecting plate is fixedly mounted on each of the one-way threaded rods, and a telescopic rod is connected between each of the connecting plates and the bottom wall of the mounting frame.

[0008] The motor drives the first gear to rotate, and the first gear drives four second gears to rotate at the same time through gear transmission, the second gear drives the fixed tube to rotate, and the fixed tube drives the threaded tube to rotate. Through the thread transmission, the threaded tube can drive the extension and retraction of the one-way threaded rod according to different rotation directions, thereby controlling the length of the bracket, replacing manual adjustment and improving the adjustment efficiency.

[0009] Preferably, two first spring rods are symmetrically fixedly installed at the bottom end of the rotating shaft, a pressure plate is commonly fixedly installed at the bottom ends of the two first spring rods, a first limit frame is fixedly installed in the fixed tube, a first limit groove is opened on the first limit frame, and a first limit block matching the first limit groove is fixedly installed on the top end of the threaded tube.

[0010] When the one-way threaded rod moves downward and encounters upward resistance from the ground, the one-way threaded rod will continue to move and lift up the threaded tube. The upward movement of the threaded tube causes the first limit block to leave the first limit groove, so that the fixed tube will no longer drive the threaded tube to rotate. The two lose their limiting function, and the one-way threaded rod automatically stops after finding a fulcrum on the ground at the bottom, replacing manual search for the fulcrum and further improving the efficiency of surveying and mapping.

[0011] Preferably, the first limiting block and the first limiting groove are both regular hexagons.

[0012] The first limit block and the first limit groove adopt a regular hexagonal structure, which can be easily clamped to each other. At the same time, such a regular cross-section can make the first limit block snap into the first limit groove more quickly, thereby improving the stability of the transmission and further improving the efficiency of surveying and mapping.

[0013] Preferably, a slide groove is provided on the mounting plate, and two sliding blocks are slidably mounted in the slide groove, and a protection frame is fixedly mounted on both of the two sliding blocks.

[0014] Two protection frames are installed on the mounting plate in a sliding manner. The protection frames can be used to protect the surveyor when the surveyor is not in use to prevent it from collision during transportation, thereby improving the quality of surveying.

[0015] Preferably, a cleaning pad is installed on each of the two protection frames.

[0016] The cleaning pad can move with the protection frame, so that the lens of the surveyor can be cleaned when the protection frame is opened and closed, further improving the quality of surveying and mapping.

[0017] Preferably, a third gear is fixedly installed on the output shaft, a first rotating rod is rotatably inserted on the side wall of the first fixed frame, a fourth gear meshing with the third gear is fixedly installed on the first rotating rod, a side frame is fixedly installed on the side wall of the mounting frame, a fifth gear and a sixth gear are rotatably installed in the side frame respectively, a bidirectional threaded rod is rotatably installed in the slide groove, the bidirectional threaded rod rotatably passes through the mounting plate and the outer wall of the side frame and is fixedly installed on the sixth gear, two sliding blocks are respectively provided with two threaded holes in opposite directions, and the two threaded holes are respectively threadedly installed between the bidirectional threaded rod.

[0018] The motor drives the third gear to rotate, the third gear drives the fourth gear to rotate, the fourth gear drives the first rotating rod to rotate, the first rotating rod drives the fifth gear to rotate, the fifth gear drives the sixth gear to rotate, and the sixth gear drives the bidirectional threaded rod to rotate. The bidirectional threaded rod is provided with two sections of threads in opposite directions. The two sliders are controlled by thread transmission to move closer to or away from each other, thereby realizing electric opening of the protective frame, which is more convenient to use.

[0019] Preferably, the transmission ratio between the third gear and the fourth gear is 1:3.

[0020] The 1:3 here is just an estimation. The main purpose is to make the rotation speed of the third gear slower than that of the fourth gear. The main function of the motor is to control the lifting and lowering of the four one-way threaded rods, so the speed should not be too fast. The protective frame can be slightly faster, so that the protective frame can be opened faster and the surveyor can be used quickly, further improving the convenience of use.

[0021] Preferably, a second rotating rod is fixedly mounted on the fifth gear, and the second rotating rod rotates and passes through the side wall of the side frame, a second fixed frame is fixedly mounted on the bottom wall of the mounting frame, the first rotating rod and the second rotating rod respectively movably pass through the side wall of the second fixed frame, a second limiting frame is fixedly mounted on one end of the first rotating rod, a second limiting groove is provided on the second limiting frame, an electromagnet is fixedly mounted in the second limiting groove, a second spring rod is fixedly mounted on one end of the second rotating rod, and a second limiting block is fixedly mounted on one end of the second spring rod.

[0022] The first rotating rod and the second rotating rod are transmitted by the limiting effect between the second limiting block and the second limiting groove. The second limiting block is sucked into the second limiting groove by the electromagnet. Since the motor controls the lifting and lowering of the one-way threaded rod, the starting time of the motor is different according to different terrains. Therefore, it is necessary to disconnect the connection between the first rotating rod and the second rotating rod after the protective frame reaches the stroke. This can be achieved in this way, which further improves the convenience of using the equipment.

[0023] Preferably, a fixing plate is fixedly installed on the mounting plate, a first feedback frame is fixedly installed on the fixing plate, two first contact electrodes are symmetrically and movably installed in the first feedback frame, a first reset spring is connected between the two first contact electrodes and the inner wall of the first feedback frame, and a first circuit breaker plate is fixedly installed on the side wall of one of the protective frames.

[0024] When the bidirectional threaded rod drives the two protection frames away from each other, the first circuit breaker plate on the protection frame gradually approaches the first feedback frame until the first circuit breaker plate is stuck between the two first contact electrodes, so that the circuit of the electromagnet is disconnected, thereby automatically stopping the transmission between the first rotating rod and the second rotating rod, realizing automatic positioning after the protection frame is opened, and further improving the convenience of equipment use.

[0025] Preferably, a second feedback frame is fixedly mounted on one of the protection frames, two second contact electrodes are symmetrically and movably mounted in the second feedback frame, a second reset spring is connected between the two second contact electrodes and the inner wall of the second feedback frame, and a second circuit breaker plate is fixedly mounted on the other protection frame.

[0026] The motor rotates in the opposite direction, so that when the two protection frames approach each other, the second circuit breaker plate gradually approaches the second feedback frame until the second circuit breaker plate is stuck between the two second contact electrodes, disconnecting the circuit of the electromagnet, and automatically disconnecting the transmission between the first rotating rod and the second rotating rod after the protection frame is closed, thereby further improving the convenience of using the equipment.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. Use the motor to drive the four threaded tubes to rotate, and control the four one-way threaded rods at the bottom to extend and retract through thread transmission, replacing manual adjustment and improving the efficiency of surveying and mapping. At the same time, the one-way threaded rod will automatically stop after finding the fulcrum.

[0029] 2. The two protection frames are controlled by motors to protect the surveyor. At the same time, the protection frames are automatically opened and closed, which is very convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] See also Figures 1 to 8 The present invention provides a land surveying and mapping device based on GIS technology, and the technical solution is as follows:

[0043] A land surveying and mapping equipment based on GIS technology comprises a mounting frame 1 and a surveying and mapping device 3. A mounting plate 2 is fixedly mounted on the upper side of the mounting frame 1, and the surveying and mapping device 3 is fixedly mounted on the mounting plate 2. A first fixing frame 4 is fixedly mounted on the bottom wall of the mounting frame 1, and a motor 5 is fixedly mounted in the first fixing frame 4. An output shaft 6 is rotatably mounted on the upper side of the motor 5, and the output shaft 6 rotates and penetrates the bottom wall of the mounting frame 1, and a first gear 8 is fixedly mounted on the output shaft 6. Four rotating shafts 7 are fixedly mounted in the mounting frame 1, and a second gear 9 meshing with the first gear 8 is fixedly mounted on the four rotating shafts 7. Fixed pipes 10 are fixedly mounted on the bottom walls of the four second gears 9, and the fixed pipes 10 movably penetrate the bottom wall of the mounting frame 1, and threaded pipes 11 are inserted at the bottom ends of the four fixed pipes 10, and a one-way threaded rod 12 is threadedly mounted on the bottom end of each threaded pipe 11, and a connecting plate 18 is fixedly mounted on each one-way threaded rod 12, and a telescopic rod 19 is connected between each connecting plate 18 and the bottom wall of the mounting frame 1.

[0044] The motor 5 drives the first gear 8 to rotate, and the first gear 8 drives four second gears 9 to rotate at the same time through gear transmission, the second gear 9 drives the fixed tube 10 to rotate, and the fixed tube 10 drives the threaded tube 11 to rotate. Through the thread transmission, the threaded tube 11 can drive the extension and retraction of the one-way threaded rod 12 according to different rotation directions, thereby controlling the length of the bracket, replacing manual adjustment and improving the adjustment efficiency. It is worth noting that the telescopic rod 19 here is to ensure that the one-way threaded rod 12 will not rotate, so that the extension and retraction of the one-way threaded rod 12 can be controlled by rotating the threaded tube 11.

[0045] As an embodiment of the present invention, refer to Figure 5Two first spring rods 16 are symmetrically fixedly installed at the bottom end of the rotating shaft 7, and a pressure plate 17 is fixedly installed at the bottom ends of the two first spring rods 16. A first limiting frame 13 is fixedly installed in the fixed tube 10, and a first limiting groove 14 is opened on the first limiting frame 13. A first limiting block 15 matching the first limiting groove 14 is fixedly installed at the top end of the threaded tube 11.

[0046] When the one-way threaded rod 12 moves downward and encounters upward resistance from the ground, the one-way threaded rod 12 will continue to move and will lift up the threaded tube 11. The threaded tube 11 moves upward so that the first limit block 15 leaves the first limit groove 14, so that the fixed tube 10 will no longer drive the threaded tube 11 to rotate. The two lose their limiting function, and the one-way threaded rod 12 automatically stops after finding a fulcrum on the ground at the bottom, instead of manually finding a fulcrum. On the contrary, after the one-way threaded rod 12 leaves the ground, under the action of gravity, the first limit block 15 will gradually re-enter the first limit groove 14, further improving the efficiency of surveying and mapping.

[0047] As an embodiment of the present invention, refer to Figure 8 The first limiting block 15 and the first limiting groove 14 are both regular hexagons.

[0048] The first limit block 15 and the first limit groove 14 adopt a regular hexagonal structure, which can be convenient for mutual clamping. At the same time, such a regular cross-section can make the first limit block 15 clamped into the first limit groove 14 more quickly, thereby improving the stability of transmission and further improving the efficiency of surveying and mapping.

[0049] As an embodiment of the present invention, refer to Figure 3 A slide groove 20 is provided on the mounting plate 2 , and two sliders 21 are slidably installed in the slide groove 20 , and a protection frame 22 is fixedly installed on the two sliders 21 .

[0050] Two protection frames 22 are installed on the mounting plate 2 in a sliding manner. The protection frames 22 can be used to protect the surveying device 3 when the surveying device 3 is not in use to prevent collision during transportation, thereby improving the quality of surveying.

[0051] As an embodiment of the present invention, refer to Figure 3 A cleaning pad 45 is respectively installed on the two protection frames 22.

[0052] The cleaning pad 45 can move together with the protection frame 22, so that when the protection frame 22 is opened and closed, the lens of the surveying device 3 can be cleaned, further improving the quality of surveying.

[0053] As an embodiment of the present invention, refer to Figure 2A third gear 24 is fixedly installed on the output shaft 6, a first rotating rod 23 is rotatably inserted on the side wall of the first fixed frame 4, a fourth gear 25 meshing with the third gear 24 is fixedly installed on the first rotating rod 23, a side frame 26 is fixedly installed on the side wall of the mounting frame 1, a fifth gear 27 and a sixth gear 28 are rotatably installed in the side frame 26, a bidirectional threaded rod 29 is rotatably installed in the slide groove 20, the bidirectional threaded rod 29 rotates through the outer wall of the mounting plate 2 and the side frame 26 and is fixedly installed on the sixth gear 28, and two sliders 21 are respectively provided with two threaded holes in opposite directions, and the two threaded holes are respectively threadedly installed between the bidirectional threaded rod 29.

[0054] The motor 5 is used to drive the third gear 24 to rotate, the third gear 24 drives the fourth gear 25 to rotate, the fourth gear 25 drives the first rotating rod 23 to rotate, the first rotating rod 23 drives the fifth gear 27 to rotate, the fifth gear 27 drives the sixth gear 28 to rotate, and the sixth gear 28 drives the bidirectional threaded rod 29 to rotate. The bidirectional threaded rod 29 is provided with two sections of threads in opposite directions. The two sliders 21 are controlled to move closer to or away from each other through the thread transmission action, thereby realizing the electric opening of the protective frame 22, which is more convenient to use.

[0055] As an embodiment of the present invention, refer to Figure 2 , the transmission ratio between the third gear 24 and the fourth gear 25 is 1:3.

[0056] The 1:3 here is just an estimate. The main purpose is to make the rotation speed of the third gear 24 smaller than that of the fourth gear 25. The main function of the motor 5 is to control the lifting and lowering of the four one-way threaded rods 12, so the speed should not be too fast, and the protective frame 22 can be slightly faster, so that the protective frame 22 can be opened faster and the surveyor 3 can be used quickly, further improving the convenience of use.

[0057] As an embodiment of the present invention, refer to Figure 2 and Figure 7 A second rotating rod 30 is fixedly installed on the fifth gear 27, and the second rotating rod 30 rotates and penetrates the side wall of the side frame 26. A second fixed frame 31 is fixedly installed on the bottom wall of the mounting frame 1. The first rotating rod 23 and the second rotating rod 30 respectively movably penetrate the side walls of the second fixed frame 31. A second limiting frame 32 is fixedly installed on one end of the first rotating rod 23, and a second limiting groove is opened on the second limiting frame 32. An electromagnet 33 is fixedly installed in the second limiting groove. A second spring rod 35 is fixedly installed on one end of the second rotating rod 30, and a second limiting block 34 is fixedly installed on one end of the second spring rod 35.

[0058] The first rotating rod 23 and the second rotating rod 30 are transmitted by the limiting effect between the second limit block 34 and the second limit groove. The second limit block 34 is sucked into the second limit groove by the electromagnet 33. Since the motor 5 controls the lifting and lowering of the one-way threaded rod 12, the starting time of the motor 5 is different according to different terrains. Therefore, it is necessary to disconnect the connection between the first rotating rod 23 and the second rotating rod 30 after the protective frame 22 reaches the stroke. This can be achieved in this way, which further improves the convenience of equipment use.

[0059] As an embodiment of the present invention, refer to Figure 6 A fixing plate 36 is fixedly mounted on the mounting plate 2, a first feedback frame 37 is fixedly mounted on the fixing plate 36, two first contact electrodes 38 are symmetrically and movably mounted in the first feedback frame 37, a first return spring 39 is connected between the two first contact electrodes 38 and the inner wall of the first feedback frame 37, and a first circuit breaker plate 40 is fixedly mounted on the side wall of one of the protective frames 22.

[0060] When the bidirectional threaded rod 29 drives the two protection frames 22 away from each other, the first circuit breaker plate 40 on the protection frame 22 gradually approaches the first feedback frame 37 until the first circuit breaker plate 40 is stuck between the two first contact electrodes 38, so that the circuit of the electromagnet 33 is disconnected. It is worth noting that the two first contact electrodes 38 are electrically connected to the electromagnet 33 circuit, thereby automatically stopping the transmission between the first rotating rod 23 and the second rotating rod 30, realizing automatic positioning of the protection frame 22 after opening, and further improving the convenience of equipment use.

[0061] As an embodiment of the present invention, refer to Figure 6 A second feedback frame 41 is fixedly mounted on one of the protection frames 22, two second contact electrodes 42 are symmetrically and movably mounted in the second feedback frame 41, a second reset spring 43 is connected between the two second contact electrodes 42 and the inner wall of the second feedback frame 41, and a second circuit breaker plate 44 is fixedly mounted on the other protection frame 22.

[0062] The motor 5 rotates in the opposite direction, so that when the two protection frames 22 approach each other, the second circuit breaker plate 44 gradually approaches the second feedback frame 41 until the second circuit breaker plate 44 is stuck between the two second contact electrodes 42, disconnecting the circuit of the electromagnet 33. It is worth noting that the two second contact electrodes 42 are electrically connected to the circuit of the electromagnet 33, so that after the protection frame 22 is closed, the transmission between the first rotating rod 23 and the second rotating rod 30 is automatically disconnected, thereby further improving the convenience of using the device. It is worth noting that the first contact electrode 38 and the second contact electrode 42 do not act on The same circuit uses two circuits to control the electromagnet 33. The two circuits are started when the motor 5 rotates forward and reverse respectively. When the motor 5 rotates reversely, the circuits of the two second contact electrodes 42 are started, and the circuit of the electromagnet 33 is connected. After the second circuit breaker plate 44 disconnects the two second contact electrodes 42, the circuit of the electromagnet 33 is disconnected. When the motor 5 rotates forward, the circuit controlled by the two first contact electrodes 38 is started. At this time, the circuit of the electromagnet 33 is connected. Until the protection plate 22 is opened, the two first contact electrodes 38 are separated, and the circuit of the electromagnet 33 is disconnected. The two circuits do not interfere with each other.

[0063] Working principle: the motor 5 drives the first gear 8 to rotate, the first gear 8 drives four second gears 9 to rotate at the same time through gear transmission, the second gear 9 drives the fixed tube 10 to rotate, the fixed tube 10 drives the threaded tube 11 to rotate, through the thread transmission effect, the threaded tube 11 can drive the extension and retraction of the one-way threaded rod 12 according to different rotation directions, thereby controlling the length of the bracket, replacing manual adjustment and improving the efficiency of adjustment.

[0064] When the one-way threaded rod 12 moves downward and encounters upward resistance from the ground, the one-way threaded rod 12 continues to move and lifts up the threaded tube 11. The threaded tube 11 moves upward so that the first limit block 15 leaves the first limit groove 14, so that the fixed tube 10 will no longer drive the threaded tube 11 to rotate. The two lose their limiting function, and the one-way threaded rod 12 automatically stops after finding a fulcrum on the ground at the bottom, replacing manual search for a fulcrum and further improving the efficiency of surveying and mapping.

[0065] Two protective frames 22 are installed on the mounting plate 2 in a sliding manner. The protective frames 22 can be used to protect the surveyor 3 when the surveyor 3 is not in use to prevent it from colliding during transportation, thereby improving the quality of surveying and mapping; the cleaning pad 45 can move with the protective frames 22, so that when the protective frames 22 are opened and closed, the lens of the surveyor 3 can be cleaned, further improving the quality of surveying and mapping.

[0066] The motor 5 is used to drive the third gear 24 to rotate, the third gear 24 drives the fourth gear 25 to rotate, the fourth gear 25 drives the first rotating rod 23 to rotate, the first rotating rod 23 drives the fifth gear 27 to rotate, the fifth gear 27 drives the sixth gear 28 to rotate, and the sixth gear 28 drives the bidirectional threaded rod 29 to rotate. The bidirectional threaded rod 29 is provided with two sections of threads in opposite directions. The two sliders 21 are controlled to move closer to or away from each other through the thread transmission action, thereby realizing the electric opening of the protective frame 22, which is more convenient to use.

[0067] The first rotating rod 23 and the second rotating rod 30 are transmitted by the limiting effect between the second limit block 34 and the second limit groove. The second limit block 34 is sucked into the second limit groove by the electromagnet 33. Since the motor 5 controls the lifting and lowering of the one-way threaded rod 12, the starting time of the motor 5 is different according to different terrains. Therefore, it is necessary to disconnect the connection between the first rotating rod 23 and the second rotating rod 30 after the protective frame 22 reaches the stroke. This can be achieved in this way, which further improves the convenience of equipment use.

[0068] When the bidirectional threaded rod 29 drives the two protection frames 22 away from each other, the first circuit breaker plate 40 on the protection frame 22 gradually approaches the first feedback frame 37 until the first circuit breaker plate 40 is stuck between the two first contact electrodes 38, so that the circuit of the electromagnet 33 is disconnected. It is worth noting that the two first contact electrodes 38 are electrically connected to the electromagnet circuit, thereby automatically stopping the transmission between the first rotating rod 23 and the second rotating rod 30, realizing automatic positioning after the protection frame 22 is opened, and further improving the convenience of equipment use; the motor 5 rotates in the opposite direction, so that when the two protection frames 22 approach each other, the second circuit breaker plate 44 gradually approaches the second feedback frame 41, until the second circuit breaker plate 44 is stuck between the two second contact electrodes 42, disconnecting the circuit of the electromagnet 33. It is worth noting that the circuit between the two second contact electrodes 42 and the electromagnet 33 The electrical connection realizes automatic disconnection of the transmission between the first rotating rod 23 and the second rotating rod 30 after the protection frame 22 is closed, thereby further improving the convenience of using the equipment. It is worth noting that the first contact electrode 38 and the second contact electrode 42 do not act on the same circuit. Two circuits are used to control the electromagnet 33. These two circuits are started when the motor 5 rotates forward and reverse respectively. When the motor 5 reverses, the circuits of the two second contact electrodes 42 are started, and the circuit of the electromagnet 33 is connected. After the second circuit breaker plate 44 disconnects the two second contact electrodes 42, the circuit of the electromagnet 33 is disconnected. When the motor 5 rotates forward, the circuit controlled by the two first contact electrodes 38 is started. At this time, the circuit of the electromagnet 33 is connected, until the protection plate 22 is opened, the two first contact electrodes 38 are separated, and the circuit of the electromagnet 33 is disconnected.
