Description

Technical Field

[0001] This application relates to the technical field of surveying and mapping devices, and in particular to a geographic information engineering surveying instrument. Background Technology

[0002] Geographic information engineering typically requires surveying and mapping to measure various spatial and geographical information and create topographic maps. For newly developed wasteland, surveying and mapping are necessary to obtain accurate topographic data, which facilitates data collection preparation for subsequent construction.

[0003] Existing geographic information engineering surveying equipment is inconvenient to use because the surveying instruments are not easy to adjust in terms of direction and height. When it is necessary to measure data of the same point in different directions, the entire equipment needs to be moved, which is quite inconvenient to use. Utility Model Content

[0004] To facilitate the adjustment of the position of the surveying instrument, this application provides a geographic information engineering surveying instrument.

[0005] This application provides a geographic information engineering surveying instrument, which adopts the following technical solution:

[0006] A geographic information engineering surveying instrument includes a support frame and a surveying device. A support platform is disposed above the support frame, and a support plate is disposed on the support platform. A rotating plate is rotatably disposed on the support plate, and the surveying device is mounted on the rotating plate. An adjustment component for adjusting the height of the support plate is disposed between the support platform and the support plate. The adjustment component includes a lifting rack and a lifting gear. The lifting rack is fixedly installed below the support plate. A moving groove for moving the lifting rack is formed on the support platform. The lifting gear is located in the moving groove and rotatably connected to the support platform. The lifting rack meshes with the lifting gear.

[0007] By adopting the above technical solution, the lifting gear is rotated, which drives the lifting rack to move up and down, thereby adjusting the height of the support plate and the height of the surveying device. The rotating plate is rotatably connected to the support plate, and the rotating plate on the support plate is rotated, thereby adjusting the angle of the surveying device, which facilitates the adjustment of the height and direction of the surveying device.

[0008] Optionally, the lifting gear is coaxially and fixedly connected to a drive shaft, and a drive motor is installed outside the support platform, with the output shaft of the drive motor being coaxially and fixedly connected to the drive shaft.

[0009] By adopting the above technical solution, the lifting gear is rotated by controlling the drive motor.

[0010] Optionally, a plurality of guide rods are provided below the support plate, and a plurality of guide grooves that cooperate with the guide rods are provided on the support platform.

[0011] By adopting the above technical solution, the guide rod moves within the guide groove during the lifting and lowering process of the support plate, thereby improving the stability of the lifting and lowering process of the support plate.

[0012] Optionally, a rotating ring is installed at the bottom of the rotating plate, and an annular groove that mates with the rotating ring is provided on the support plate. The rotating ring is located in the annular groove and is rotatably connected to the support plate.

[0013] By adopting the above technical solution, the rotating ring is in the ring groove, and by rotating the rotating ring in the ring groove, the rotating plate rotates on the support plate.

[0014] Optionally, the outer wall of the rotating ring is provided with external teeth, a rotating gear is rotatably connected inside the support plate, the rotating gear meshes with the external teeth of the rotating ring, and a rotating shaft passes through the support plate, the rotating shaft and the rotating gear being coaxially and fixedly connected.

[0015] By adopting the above technical solution, the rotating gear is rotated by the rotating shaft, and the rotating ring is driven to rotate by the external teeth meshing with the rotating gear, thereby rotating the rotating plate on the support plate.

[0016] Optionally, the support plate has a connecting groove communicating with the annular groove. A limit rod is slidably connected in the connecting groove. The end of the limit rod is provided with a limit block that engages with the tooth gap of the outer teeth of the rotating ring. An intermediate gear is rotatably connected in the connecting groove. A pressing rod is provided on the outer wall of the support plate. The side walls of the limit rod and the pressing rod are provided with movable racks that mesh with the intermediate gear. A spring is provided in the connecting groove. The two ends of the spring are fixedly connected to the end of the limit rod and the inner wall of the connecting groove. When the spring is in its natural state, the limit block is located in the tooth gap of the outer teeth of the rotating ring.

[0017] By adopting the above technical solution, when the rotating plate needs to be rotated, the pressing rod is moved towards the support plate. The moving rack and intermediate gear drive the limiting rod to move away from the rotating ring. The limiting block separates from the outer teeth of the rotating ring, thereby rotating the rotating ring. During the process of the limiting rod moving away from the rotating ring, the spring is compressed, applying a force towards the rotating ring to the limiting rod. After the pressing rod is released, the compressed spring pushes the limiting rod to move towards the rotating ring, causing the limiting block to insert into the tooth gap of the outer teeth of the rotating ring, preventing the rotating ring from rotating and improving the stability of the rotating plate on the support plate.

[0018] Optionally, casters are installed at all four corners of the bottom of the support frame.

[0019] By adopting the above technical solution, the entire device can be easily moved using casters.

[0020] Optionally, the support frame is provided with a push rod.

[0021] By adopting the above technical solution, the support frame can be easily moved using a push rod.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] Rotating the lifting gear drives the lifting rack to move up and down, thereby adjusting the height of the support plate and the height of the surveying device. The rotating plate is rotatably connected to the support plate. Rotating the rotating plate on the support plate adjusts the angle of the surveying device, making it convenient to adjust the height and direction of the surveying device.

[0024] The rotating shaft rotates the rotating gear, and the external teeth meshing with the rotating gear drive the rotating ring to rotate, thereby rotating the rotating plate on the support plate and adjusting the direction of the surveying device. Attached Figure Description

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses a geographic information engineering surveying instrument.

[0031] Reference Figure 1 and Figure 2A geographic information engineering surveying instrument includes a support frame 1 and a surveying device 2. A support platform 3 is arranged above the support frame 1, and a support plate 4 is arranged on the support platform 3. A rotating plate 5 is rotatably arranged on the support plate 4. The surveying device 2 is mounted on the rotating plate 5. An adjustment component 6 for adjusting the height of the support plate 4 is arranged between the support platform 3 and the support plate 4. The adjustment component 6 includes a lifting rack 61 and a lifting gear 62. The lifting rack 61 is fixedly installed below the support plate 4. A moving groove for the lifting rack 61 to move is opened on the support platform 3. The lifting gear 62 is located in the moving groove and is rotatably connected to the support platform 3. The lifting rack 61 and the lifting gear 62 mesh. A drive shaft is coaxially fixedly connected to the lifting gear 62. A drive motor 63 is installed outside the support platform 3. The output shaft of the drive motor 63 is coaxially fixedly connected to the drive shaft. The lifting gear 62 is rotated by the drive motor 63. When the drive motor 63 is started, the lifting gear 62 rotates, which drives the lifting rack 61 to move up and down, thereby adjusting the height position of the support plate 4 and the height position of the surveying device 2. The rotating plate 5 is rotatably connected to the support plate 4. Rotating the rotating plate 5 on the support plate 4 adjusts the angle of the surveying device 2, making it convenient to adjust the height and direction of the surveying device 2.

[0032] Reference Figure 1 The support frame 1 is equipped with casters 11 at each of its four corners. The casters 11 facilitate the movement of the entire device. A push rod 12 is also provided on the support frame 1. The push rod 12 facilitates the movement of the support frame 1.

[0033] Reference Figure 1 Multiple guide rods 41 are provided below the support plate 4, and several guide grooves that cooperate with the guide rods 41 are provided on the support platform 3. During the lifting and lowering movement of the support plate 4, the guide rods 41 move within the guide grooves, improving the stability of the lifting and lowering movement of the support plate 4.

[0034] Reference Figure 2 and Figure 3 A rotating ring 51 is installed at the bottom of the rotating plate 5. An annular groove 42 that mates with the rotating ring 51 is provided on the support plate 4. The rotating ring 51 is located in the annular groove 42 and is rotatably connected to the support plate 4. The rotating ring 51 is in the annular groove 42. By rotating the rotating ring 51 in the annular groove 42, the rotating plate 5 rotates on the support plate 4.

[0035] Reference Figure 2 and Figure 3The outer wall of the rotating ring 51 is provided with external teeth, and a rotating gear 7 is rotatably connected inside the support plate 4. The rotating gear 7 meshes with the external teeth of the rotating ring 51. A rotating shaft 71 passes through the support plate 4 and is coaxially and fixedly connected to the rotating gear 7. The rotating gear 7 is rotated by the rotating shaft 71, and the rotating ring 51 is driven to rotate by the external teeth meshing with the rotating gear 7, thereby rotating the rotating plate 5 on the support plate 4.

[0036] Reference Figure 3 The support plate 4 has a connecting groove 43 that communicates with the ring groove 42. A limit rod 8 is slidably connected in the connecting groove 43. The end of the limit rod 8 is provided with a limit block 81 that cooperates with the tooth gap of the outer tooth of the rotating ring 51. An intermediate gear 91 is rotatably connected in the connecting groove 43. A push rod 9 is provided on the outer wall of the support plate 4. The side walls of the limit rod 8 and the push rod 9 are provided with a movable rack 82 that meshes with the intermediate gear 91. A spring 83 is provided in the connecting groove 43. The two ends of the spring 83 are fixedly connected to the end of the limit rod 8 and the inner wall of the connecting groove 43. When the spring 83 is in its natural state, the limit block 81 is located in the tooth gap of the outer tooth of the rotating ring 51. When it is necessary to rotate the rotating plate 5, the pressing rod 9 is moved towards the support plate 4. The moving rack 82 and the intermediate gear 91 drive the limiting rod 8 to move away from the rotating ring 51. The limiting block 81 separates from the outer teeth of the rotating ring 51, thereby rotating the rotating ring 51. During the process of the limiting rod 8 moving away from the rotating ring 51, the spring 83 is compressed, applying a force towards the rotating ring 51 to the limiting rod 8. After the pressing rod is released, the compressed spring 83 pushes the limiting rod 8 to move towards the rotating ring 51, so that the limiting block 81 is inserted into the tooth gap of the outer teeth of the rotating ring 51, preventing the rotating ring 51 from rotating and improving the stability of the rotating plate 5 on the support plate 4.

[0037] The implementation principle of a geographic information engineering surveying instrument according to an embodiment of this application is as follows: the drive motor 63 controls the lifting gear 62 to rotate, and the rotation of the lifting gear 62 drives the lifting rack 61 to move up and down, thereby adjusting the height position of the support plate 4 and the height position of the surveying device 2. The rotating plate 5 is rotatably connected to the support plate 4. Rotating the rotating plate 5 on the support plate 4 adjusts the angle of the surveying device 2, making it convenient to adjust the height and direction of the surveying device 2.
