[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0025] Example 1, as Figures 1 to 6As shown, an urban three-dimensional terrain auxiliary mapping device includes a cart 1, a lifting mechanism 2 is fixedly connected to the rear part of the inner cavity of the cart 1, a placement mechanism 5 is slidably connected to the upper side of the front of the cart 1, a surveying instrument 6 is installed on the upper end of the placement mechanism 5, a transmission mechanism 4 is fixedly connected to the rear wall of the cart 1, and a fixing mechanism 3 is fixedly connected to the lower part of the outer surface of the lifting mechanism 2.
[0026] During the specific implementation of the present invention, the internal driving structure of the lifting mechanism 2 is first activated, and the placing mechanism 5 is driven to rise from the inner cavity of the cart 1 to the top of the cart 1 through the internal driving structure of the lifting mechanism 2. While driving the placing mechanism 5 to rise, the internal structure of the transmission mechanism 4 is driven to move through the internal structure of the lifting mechanism 2, so that the internal structure of the transmission mechanism 4 drives the internal structure of the fixing mechanism 3 to extend from the bottom of the cart 1 and contact the ground, so that the internal structure of the fixing mechanism 3 fixes the entire device, thereby preventing inaccurate measurement data caused by the shaking of the cart 1 during the measurement process;
[0027] Then the prepared surveying instrument 6 is placed on top of the placement mechanism 5, and then the surveying instrument 6 can be fixed by rotating the internal structure of the placement mechanism 5 so that it will not shake or vibrate due to external force during use. Then the operator starts the surveying instrument 6 to perform surveying operations. When the surveying at one location is completed and it needs to be moved to another location for surveying, the internal structure of the lifting mechanism 2 is started to drive the placement mechanism 5 down into the inner cavity of the cart 1, and then the placement mechanism 5 is lowered to drive the surveying instrument 6 down into the inner cavity of the cart 1 for storage. At the same time, the lifting mechanism 2 is operated to cancel the fixation of the fixing mechanism 3, so that the cart 1 can be moved, and then the operator pushes the cart 1 to move to the next surveying location for surveying.
[0028] The surveying instrument 6 mentioned above can use the total station, level, theodolite and laser scanner in the existing technology to perform surveying and mapping operations. The total station, level, theodolite and laser scanner mentioned above all have automatic leveling function, which will not be elaborated in detail in this utility model.
[0029] In order to achieve the purpose of driving the placement mechanism 5 to move up and down, refer to Figure 2In this solution, the lifting mechanism 2 includes a fixed box 21 and a motor 25. The fixed box 21 is fixedly connected to the rear side of the bottom wall of the inner cavity of the cart 1. The left and right sides of the upper wall of the inner cavity of the fixed box 21 are rotatably connected to the threaded rods 22. The motor 25 is fixedly connected to the rear side of the middle part of the right wall of the cart 1. The left and right sides of the front end of the fixed box 21 are provided with slide grooves 26. The lower ends of the two threaded rods 22 are jointly fixedly connected to a pulley assembly 23. The pulley assembly 23 consists of two pulleys and a belt. The lower side of the pulley on the right is fixedly connected to a gear set 27. The gear set 27 consists of two meshing bevel gears. The middle part of the bevel gear located in the vertical direction is fixedly connected to a rotating rod 24.
[0030] Furthermore, the right end of the rotating rod 24 is rotatably connected and passes through the inner surface of the fixed box 21 to extend to the outside, and the output end of the motor 25 is fixedly connected to the right end of the rotating rod 24 through a coupling.
[0031] In the above, the motor 25 is started to drive the rotating rod 24 to rotate, and the rotating rod 24 rotates while driving the bevel gear to rotate, and the rotation of the bevel gear drives the pulley to rotate, and then the two threaded rods 22 are driven to rotate at the same time under the action of the provided belt 1, and the two threaded rods 22 rotate while driving the internal structure of the placement mechanism 5 to slide up and down in the inner cavity of the slide groove 26, thereby achieving the purpose of driving the surveying instrument 6 to rise and fall.
[0032] The specific installation method of the motor 25, the circuit connection method and the control method used in the above are all conventional designs and will not be elaborated in detail in this utility model.
[0033] Specifically, in order to achieve the purpose of fixing the surveying instrument 6, refer to Figure 3 In this solution, the placement mechanism 5 includes a placement platform 51, which is threadedly connected to the outer surfaces of the two threaded rods 22. The front end of the upper end of the placement platform 51 is fixedly connected to a suction cup 52, and the lower end of the suction cup 52 is fixedly connected to an air pipe 53. The front end of the right side of the air pipe 53 is fixedly connected to a round tube 54, and the inner cavity of the round tube 54 is slidably connected to a piston plate 55. The front end of the piston plate 55 is fixedly connected to a screw 56, and the outer surface of the screw 56 is threadedly connected to the front wall of the inner cavity of the placement platform 51.
[0034] In the above, the purpose of lifting is achieved by threading the rear side of the placement table 51 to the surfaces of the two threaded rods 22, and then the prepared surveying instrument 6 is placed on the upper end of the placement table 51 and the upper surface of the suction cup 52, so that the surveying instrument 6 and the inner cavity of the suction cup 52 are sealed. Then, by rotating the screw 56, the piston plate 55 is driven to rotate and move forward in the inner cavity of the circular tube 54, so that the air pressure in the air pipe 53 and the inner cavity of the suction cup 52 gradually decreases, forming a negative pressure environment lower than the external atmospheric pressure, so that the suction cup 52 tightly absorbs the bottom of the surveying instrument 6 to achieve the purpose of fixing it.
[0035] Specifically, in order to prevent the cart 1 from moving during the use of the surveying instrument 6, refer to Figure 4 In this solution, the fixing mechanism 3 includes a fixing plate 33, which is fixedly connected to the lower side of the outer surface of the fixing box 21. The upper end and the middle part of the lower end of the fixing plate 33 are fixedly connected to a spring 1 32. The upper end of the spring 1 32 on the upper side and the lower end of the spring 1 32 on the lower side are fixedly connected to a slide plate 1 31 and a slide plate 2 35 respectively. The slide plate 1 31 and the slide plate 2 35 are both slidably connected to the outer surface of the fixing box 21. The lower end of the slide plate 2 35 is fixedly connected to a number of fixing columns 36. The several fixing columns 36 all pass through the bottom wall of the cart 1 and extend to the outside.
[0036] In the above description, when the placement platform 51 leaves the upper end of the slide plate 1 31, the compression of the upper spring 1 32 is canceled, so that the spring 1 32 pushes the slide plate 1 31 to slide upward on the surface of the fixed box 21, so that the slide plate 1 31 drives the internal structure of the transmission mechanism 4 to operate while sliding upward, so that the internal structure of the transmission mechanism 4 cancels the lock on the slide plate 2 35, and then pushes the slide plate 2 35 down through the spring 1 32 on the lower side, so that the slide plate 2 35 drives the several fixed columns 36 to contact the ground, thereby achieving the purpose of fixing the cart 1 and preventing it from sliding.
[0037] Specifically, in order to achieve the purpose of fixing the entire device when the surveying instrument 6 is in use and canceling the lock of the cart 1 when the surveying instrument 6 is stored, the transmission mechanism 4 includes two support plates 41 and a friction plate 42. The two support plates 41 are respectively fixedly connected to the left and right sides of the middle part of the rear wall of the inner cavity of the cart 1, and the friction plate 42 is fixedly connected to the right side of the lower end of the slide plate 31. A rotating column 43 is connected to the opposite surfaces of the two support plates 41 for common rotation. A friction wheel 44 is fixedly connected to the right side of the outer surface of the rotating column 43, and a gear 45 is fixedly connected to the left side of the outer surface of the rotating column 43.
[0038] Furthermore, the front side of the outer surface of the gear 1 45 is meshedly connected with a rack 46 , and the lower front end of the outer surface of the rack 46 is fixedly connected to the rear end of the slide 2 35 .
[0039] In the above description, when the placement platform 51 and the surveying instrument 6 need to be stored in the inner cavity of the cart 1, the placement platform 51 is driven to descend by the threaded rod 22, so that the placement platform 51 descends and enters the inner cavity of the cart 1 to squeeze the slide plate 31, so that the slide plate 31 descends and drives the friction plate 42 to descend. When the friction plate 42 descends, it contacts the surface of the friction wheel 44, so that the friction wheel 44 drives the rotating column 43 to rotate, and the rotation of the rotating column 43 drives the gear 1 45 to rotate. Then, the gear 1 45 rotates and drives the rack 46 meshed with it to rise, and then the rack 46 drives the slide plate 2 35 to rise, so that the slide plate 2 35 drives the fixed columns 36 off the ground to cancel the lock on the cart 1;
[0040] Then, when the surveying instrument 6 needs to be used, the placement table 51 is lifted off the surface of the slide plate 31, and then the spring 32 on the upper side pushes the slide plate 31 to rise, driving the friction plate 42 to lift, so that the friction plate 42 drives the friction wheel 44 to rotate in the opposite direction, driving the rotating column 43 to rotate, and then driving the gear 45 to rotate in the opposite direction, so that it drives the rack 46 to descend, so that the slide plate 35 drives the fixing column 36 to contact the ground, thereby achieving the purpose of fixing the cart 1.
[0041] It should be noted that the specific installation method of the motor 25, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
