Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping instrument devices, and specifically refers to a rotating platform for a surveying and mapping instrument used in geological surveying and mapping. Background Art

[0002] Geological surveying and mapping is an important link in geological exploration work, and geological surveying and mapping instruments play a key role in it. A geological surveying and mapping instrument is a kind of instrument and equipment specifically used to measure geological terrain, geomorphic features, geological structures and other information. It can accurately obtain geological data such as coordinates, elevations, angles, etc. These data are of irreplaceable significance for geological research, mineral exploration, geological surveys in the early stage of engineering construction, etc. In geological surveying and mapping work, in order to achieve all-round and multi-angle surveying and mapping operations, the surveying and mapping instrument often needs to be installed on a rotating platform. The rotating platform can conveniently adjust the direction of the surveying and mapping instrument, thereby ensuring that the surveying and mapping instrument can cover geological areas in different directions and obtain more comprehensive and accurate geological information.

[0003] Traditional rotating platforms for surveying and mapping instruments have deficiencies in leveling. Due to the complex and changeable working environment of geological surveying and mapping, such as when operating in mountainous areas, hilly areas and other terrains with uneven terrain, it is very difficult for the rotating platform to quickly and accurately adjust to the horizontal state. Traditional platforms may lack precise horizontal adjustment devices or the adjustment process is cumbersome, which leads to measurement data being prone to errors when the surveying and mapping instrument works in a non-horizontal state.

[0004] Traditional rotating platforms for surveying and mapping instruments have limitations in adjusting the spread angle of the support feet. Different geological surveying and mapping environments have different requirements for the spread angle of the support feet of the rotating platform. For example, in narrow valleys or steep slopes, it is necessary to adjust the spread angle of the support feet to adapt to the terrain to ensure the stability of the platform. However, the spread angle adjustment structure of traditional rotating platforms is often not flexible enough, and the adjustment range is limited, and it cannot well adapt to various complex geological terrain environments. Summary of the Utility Model

[0015] (III) Technical effects

[0016] The advantages of the present utility model compared with the prior art are as follows:

[0017] 1. The front and side of the support platform of this rotating platform are both equipped with bubble levels, which can intuitively display the horizontal state of the platform. At the same time, a horizontal adjusting rod is inserted at the bottom of the support leg, and the horizontal adjusting rod and the support leg are limited by a limiting mechanism. This structure makes the leveling operation more precise. The operator can adjust the height of each support leg by adjusting the horizontal adjusting rod according to the display of the bubble level, so as to quickly adjust the platform to the horizontal state and reduce the measurement error of the surveying instrument caused by the non-horizontal platform.

A connecting rod is hinged between the adjusting sleeve and the support leg, and the adjusting sleeve and the central rod are fixed by a fastening mechanism. This structure enables the opening and closing angle of the support leg to be flexibly adjusted. By sliding the position of the adjusting sleeve on the central rod, the connecting rod is used to drive the support leg to change the opening angle, and then the position of the adjusting sleeve is fixed with a fastening bolt. This can adapt to various complex geological terrains. For example, in a narrow valley, the opening angle of the support leg can be adjusted to be smaller for placing the platform; on a relatively open but uneven hillside, the opening angle of the support leg can be adjusted to be larger to increase the stability of the platform.

A horizontal adjusting rod 8 for adjusting the level of the rotating platform is inserted at the bottom of the support feet 2. A limiting mechanism 9 is provided in a matching manner between the horizontal adjusting rod 8 and the support feet 2. Bubble levels 20 are provided on both the front and side surfaces of the support platform 1. A rubber anti-slip pad 23 is fixedly provided on the upper end surface of the bearing plate 4. A storage battery 24 for supplying power to the motor 6 is fixedly provided at the bottom of the support platform 1.

[0030] In this embodiment, as a preferred technical solution, the adjusting structure includes a central rod 10 fixedly arranged at the center of the bottom of the support platform 1. An adjusting sleeve 11 is slidably sleeved on the central rod 10. A connecting rod 12 is hinged between the adjusting sleeve 11 and the support leg 2. A fastening mechanism 13 for fixing the position of the adjusting sleeve 11 is arranged in a matching manner between the adjusting sleeve 11 and the central rod 10. The fastening mechanism 13 includes a plurality of threaded holes 14 arranged on the side surface of the central rod 10, and further includes a fastening bolt 15 threadedly connected to the side surface of the adjusting sleeve 11. The fastening bolt 15 is adapted to the threaded hole 14.

[0031] In this embodiment, as a preferred technical solution, the clamping assembly 5 includes vertical plates 16 fixedly arranged on the left and right sides of the upper end of the bearing plate 4. An adjusting bolt 17 is threadedly connected to the vertical plate 16. An arc-shaped clamping plate 18 is rotatably arranged at one end of the adjusting bolt 17 extending into the vertical plate 16.

The limiting bolt 22 is adapted to the threaded hole II 21.

[0033] The working principle of a surveying instrument rotating platform for geological surveying of the present utility model is as follows: When the motor 6 is started, the driving shaft of the motor 6 drives the driving gear 7 to rotate. Since the driving gear 7 meshes with the gear on the outer ring of the slewing bearing 3, the rotation of the driving gear 7 causes the rotating outer ring of the slewing bearing 3 to rotate relative to the inner ring. The upper end surface of the rotating outer ring of the slewing bearing 3 is fixedly connected with the bearing plate 4, and the surveying instrument is fixed on the upper end surface of the bearing plate 4 through the clamping assembly 5, thus realizing the stable rotation of the surveying instrument on the support platform 1. The horizontal state of the platform is judged by observing the bubble level 20 on the front and side of the support platform 1. If the platform is not horizontal, the horizontal adjusting rod 8 at the bottom of the support leg 2 can be adjusted. A plurality of threaded holes II 21 are arranged on the side surface of the horizontal adjusting rod 8, and the limiting bolt 22 is threadedly connected to the bottom of the support leg 2. After loosening the limiting bolt 22, the horizontal adjusting rod 8 can be moved up and down to adjust the height of the support leg 2, so that the bubble in the bubble level 20 is located at the central position, thereby achieving the purpose of leveling the platform. When adjusting the opening and closing angle of the support leg 2, first loosen the fastening bolt 15 in the fastening mechanism 13. The fastening bolt 15 is threadedly connected to the side surface of the adjusting sleeve 11. The adjusting sleeve 11 is slidably sleeved on the central rod 10 at the center of the bottom of the support platform 1. A plurality of threaded holes 14 are arranged on the side surface of the central rod 10. The adjusting sleeve 11 and the support leg 2 are hinged through the connecting rod 12. When the adjusting sleeve 11 slides on the central rod 10, through the transmission of the connecting rod 12, the support leg 2 is driven to change the opening and closing angle. After adjusting to the appropriate angle, then tighten the fastening bolt 15 to fix the adjusting sleeve 11 on the central rod 10.

[0034] The usage process of a rotating platform of a surveying instrument for geological surveying of the present utility model is as follows:

[0035] 1. Placement and preliminary adjustment. First, carry the rotating platform of the surveying instrument to the designated location for geological surveying work. Observe the terrain preliminarily, roughly estimate the opening and closing angle of the supporting feet 2 according to the terrain, loosen the fastening bolt 15 in the fastening mechanism 13, slide and adjust the position of the adjusting sleeve 11 on the central rod 10 according to the estimated angle, drive the supporting feet 2 through the connecting rod 12 to adjust the opening and closing angle, and tighten the fastening bolt 15 after adjustment.

[0036] 2. Platform leveling. Check the bubble level 20 on the front and side of the support platform 1. If the bubble is not in the central position, for the supporting feet 2 that need to be adjusted, loosen the limit bolt 22 at its bottom, move the horizontal adjusting rod 8 up or down according to the deviation direction of the bubble. Continuously observe the bubble level 20 during the adjustment process. When the bubble is in the central position, tighten the limit bolt 22 to complete the platform leveling operation.

[0037] 3. Surveying instrument installation. Place the surveying instrument on the bearing plate 4. The rubber anti-slip pad 23 on the upper end surface of the bearing plate 4 can prevent the surveying instrument from sliding. Rotate the adjusting bolt 17 in the clamping assembly 5. One end of the adjusting bolt 17 extending into the vertical plate 16 is rotatably connected to the arc-shaped clamping plate 18. A guide rod 19 is fixed on the outer side of the arc-shaped clamping plate 18. The guide rod 19 passes through the vertical plate 16 and is slidably matched with the vertical plate 16. By rotating the adjusting bolt 17, the arc-shaped clamping plate 18 moves towards the surveying instrument until the surveying instrument is tightly clamped and fixed on the bearing plate 4.

[0038] 4. Surveying instrument rotation operation. Start the motor 6 at the bottom of the support platform 1. The driving shaft of the motor 6 drives the driving gear 7 to rotate. The driving gear 7 interacts with the gear on the outer ring of the slewing bearing 3, so that the rotating outer ring of the slewing bearing 3 rotates, and then drives the bearing plate 4 and the surveying instrument fixed thereon to rotate. According to the requirements of geological surveying, adjust the rotation direction and angle of the motor 6 so that the surveying instrument can conduct surveying operations on geological areas in different directions.

[0039] 5. End of work. After the geological surveying work is completed, turn off the motor 6, loosen the adjusting bolt 17 in the clamping assembly 5, remove the surveying instrument. If it is necessary to transfer the working location, loosen the fastening bolt 15 in the fastening mechanism 13 again, adjust the opening and closing angle of the supporting feet 2 to a state suitable for handling, and then carry the rotating platform of the surveying instrument to a new working location or storage location.

[0040] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
