Description

Technical Field

[0001] This utility model relates to the field of geographic information technology, and in particular to a omnidirectional adjustable measurement and mapping device. Background Technology

[0002] Surveying and mapping equipment refers to the devices and tools used for geographic information collection, data measurement, and topographic mapping. They are widely used in land surveying, construction engineering, resource investigation, and environmental monitoring. These devices include, but are not limited to, total stations, GPS receivers, rangefinders, levels, laser scanners, drones, and aerial photography equipment, which can accurately acquire information such as the spatial location, size, and shape of the earth's surface, objects, or buildings.

[0003] For example, Chinese Patent Publication No. (CN212931434U) discloses a fully adjustable geographic information surveying and mapping device, which describes: "It includes a tracked chassis, a support platform with multiple pillars erected above the tracked chassis, and a lifting ground environment surveying device installed on the support platform. A power supply system and a hydraulic station are provided on the tracked chassis. The lifting ground environment surveying device includes a fixed support platform, a fixed rotating platform, a rotating frame, a rotary drive motor, vertical fixed pillars, an up-and-down moving platform, a moving drive motor, a rotating platform, and a rotary motor. A geographic information mapping instrument, a camera, and a signal processor are installed on the rotating platform. The power supply system provides power to the entire system, and the hydraulic station provides hydraulic power to the entire system. This utility model's lifting ground environment surveying device can adjust the vertical height, horizontal rotation angle, and vertical rotation angle as needed, enabling precise full-range mapping."

[0004] In summary, the device also has the following technical problems: In existing measurement and mapping processes, tripods are often used to support the measurement and mapping instruments. When measuring some mapping equipment, the height of the tripod needs to be adjusted due to obstruction on one side. However, when adjusting the overall height of the mapping device, the entire tripod needs to be moved, which may cause the structure supporting the mapping instrument to become unstable and easily affected by external disturbances, resulting in shaking and affecting the accuracy of the measurement. Therefore, it is necessary to propose a fully adjustable measurement and mapping device to provide a new technical solution to solve the technical problems mentioned in the above patent.

[0005] Based on this, it is necessary to provide a fully adjustable measurement and mapping device to address the aforementioned technical problems. By setting up a height adjustment structure, when the surveyor needs to be adjusted at a point, the first and second toothed plates are retracted towards the center by rotating the central shaft and engaging the gears. This, in turn, can be used with the first and second extension rods to push the surveyor up from its center point, thereby effectively solving the problem of frequent movement during height adjustment of the surveyor.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] As described in the background art, tripods are often used to support surveying instruments in existing surveying and mapping processes. When some surveying equipment is being measured, the height of the tripod needs to be adjusted because of obstructions on one side. However, when adjusting the overall height of the surveying device, the entire tripod needs to be moved, which may cause the structure supporting the surveying instrument to become unstable and easily affected by external disturbances, resulting in shaking and affecting the accuracy of the surveying.

[0029] To solve this technical problem, this utility model provides an all-around adjustable measurement and mapping device, which is applied to the adjustment of geographic information measurement and mapping devices.

[0032] The all-around adjustable measuring and drawing device provided by this utility model, by setting a height adjustment structure 1, when the measuring instrument 3 is set at a point and needs to be adjusted in height, the first toothed plate 6 and the second toothed plate 10 are retracted to the center by rotating the central shaft 15 in conjunction with the gear 24. This, in turn, can be used with the first extension rod 8 and the second extension rod 12 to push the measuring instrument 3 to rise around the center point of the measuring instrument 3, thereby effectively solving the problem of frequent movement of the measuring instrument 3 during height adjustment.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1:

[0035] Please refer to Figures 4-6 A 360° adjustable measurement and mapping device includes a surveying instrument 3, a height adjustment structure 1 for adjusting the height of the surveying instrument 3 at the bottom end, and a horizontal adjustment mechanism 2 for adjusting the horizontal position of the surveying instrument 3 on both sides of the height adjustment structure 1.

[0036] The height adjustment structure 1 includes a positioning support frame 4, the interior of which is provided with a sliding cavity 5, and the upper end of the sliding cavity 5 is provided with a top support plate 9.

[0037] Specifically, the inner wall of the sliding cavity 5 is slidably connected to a first toothed plate 6, one end of the first toothed plate 6 is fixedly connected to a first shaft 7, the surface of the first shaft 7 is rotatably connected to a first extension rod 8, and the end of the first extension rod 8 away from the first shaft 7 is hinged to the top bearing plate 9.

[0038] Specifically, a second toothed plate 10 is slidably connected inside the sliding cavity 5. A second rotating shaft 11 is fixedly connected to one end of the second toothed plate 10. A second extension rod 12 is rotatably connected to the surface of the second rotating shaft 11. The end of the second extension rod 12 away from the second rotating shaft 11 is hinged to the top bearing plate 9.

[0039] Specifically, a second support rod 13 is rotatably connected to the middle of the second extension rod 12, and the end of the second support rod 13 away from the second extension rod 12 is hinged to the positioning support frame 4. A first support rod 14 is rotatably connected to the middle of the first extension rod 8, and the end of the first support rod 14 away from the first extension rod 8 is hinged to the positioning support frame 4.

[0040] Specifically, the positioning support frame 4 has a central shaft 15 rotatably connected inside, a handwheel 16 is fixedly connected to one end of the central shaft 15, a handwheel 16 is fixedly connected to the surface of the central shaft 15, a gear 24 meshes with the first toothed plate 6 and the second toothed plate 10, a ratchet 17 is fixedly connected to the end of the central shaft 15 away from the handwheel 16, a positioning rod 18 is fixedly connected to the surface of the positioning support frame 4, a ratchet 19 is rotatably connected to the surface of the positioning rod 18, a torsion spring 20 is sleeved on the surface of the positioning rod 18, and the two ends of the torsion spring 20 are fixedly connected to the positioning support frame 4 and the ratchet 19 respectively.

[0041] With the above structural design, when using the device, it is first placed in a fixed position. When adjusting the height, the central shaft 15 is rotated by turning the handwheel 16. At the same time, the central shaft 15 rotates, which in turn drives the gear 24 to rotate. As the gear 24 rotates, the first toothed plate 6 and the second toothed plate 10 can be retracted to the middle. While the first toothed plate 6 and the second toothed plate 10 are retracting, the top support plate 9 can be pushed to rise stably through the first extension rod 8 and the second extension rod 12, thereby realizing the height adjustment of the surveying instrument 3.

[0042] As the central shaft 15 rotates, it drives the ratchet 17 to rotate. The rotation of the ratchet 17 can move the ratchet 19 to rotate on the surface of the positioning rod 18. With the cooperation of the ratchet 17, the ratchet 19 and the torsion spring 20, the central shaft 15 can be locked, thereby ensuring the height of the surveying instrument 3 is locked.
