Description

Technical Field

[0001] The utility model relates to an RTK single-pole centering device, belonging to the technical field of measuring equipment. Background Art

[0002] The most commonly used RTK single pole is a retractable carbon fiber centering pole. The retractable part is made of aluminum alloy and the fixed part is made of carbon fiber insulation material. The length after contraction is 1.25m, and the length after full extension is 2.25m. The diameter of the carbon fiber part is 2.5cm. During the field measurement, the bottom of the centering pole is placed at the standard center position of the control point. The single pole is vertically upward, with the circular level bubble 1.25m above the upper part as the center. The control points, image control points, base points, boundary stakes and other points that need to be measured are measured. The height of the single pole can be freely adjusted from 1.25m to 2.25m.

[0003] However, when measuring boundary points and observing points above the ground such as pier tops and wall tops, after the surveyors set up the single rod, the circular level bubble is often higher than the visual height, and the circular level bubble cannot be seen. It is impossible to ensure that the single rod is vertical, which brings large errors to the measurement. Utility Model Content

[0025] The present invention is described in detail below in conjunction with embodiments, but the present invention is not limited to these embodiments.

[0026] The utility model provides an RTK single-pole centering device, such as Figures 1 to 3 As shown, the device comprises:

[0027] A centering rod 1 is provided with a first circular level 2 thereon.

[0028] The extension rod 3 has one end detachably connected to the bottom end of the centering rod 1 ; a second circular level 4 is provided on the extension rod 3 ; the length of the extension rod 3 is shorter than that of the centering rod 1 .

[0029] The connecting end of the integrated pointed head 5 is detachably connected to the end of the extension rod 3 away from the centering rod 1 .

[0030] Furthermore, the device also includes:

[0031] The bubble seat 6 is connected to the extension rod 3, and the second circular level 4 is fixed on the bubble seat 6. After the bubble seat 6 is installed on the extension rod 3, the bubble in the second circular level 4 needs to be accurately adjusted.

[0032] In practical applications, the second circular level 4 is fixed on the bubble seat 6, and the bubble seat 6 is fixed to the middle position of the extension rod 3 through a fixing member 7. The fixing member 7 can be a fixing screw.

[0033] Preferably, the upper surface of the bottom plate of the bubble seat 6 is a luminous surface. In this way, the second circular level 4 can be conveniently used for centering and leveling in an environment with poor light (such as at night).

[0034] In the embodiment of the utility model, the extension rod 3 is a hollow rod, which can reduce the weight of the entire device.

[0035] The length of the extension rod 3 can be set to 8 cm to 12 cm. For example, it can be 8 cm, 10 cm or 12 cm. Of course, the length of the extension rod 3 can also be appropriately increased or decreased according to actual needs.

[0036] The extension rod 3 is threadedly connected to the centering rod 1. Specifically, a first threaded hole 31 is provided at the top end of the extension rod 3, and a first bolt 11 is provided at the bottom end of the centering rod 1. The first bolt 11 and the first threaded hole 31 are matched and connected to realize the connection between the extension rod 3 and the centering rod 1.

[0037] The extension rod 3 is threadedly connected to the integrated tip 5. Specifically, a second bolt 32 is provided at the bottom end of the extension rod 3, and a second threaded hole 51 is provided at the connecting end of the integrated tip 5. The second bolt 32 and the second threaded hole 51 are matched and connected to realize the connection between the extension rod 3 and the integrated tip 5.

[0038] In the embodiment of the present invention, the difference between the diameter of the extension rod 3 and the diameter of the centering rod 1 is less than or equal to 0.5 cm. Preferably, the diameter of the extension rod 3 is consistent with the diameter of the centering rod 1. For example, the diameter can be 2.5 cm.

[0039] The embodiment of the utility model does not limit the material of the extension rod 3. In practical applications, the material of the extension rod 3 can be aluminum alloy or carbon fiber.

[0040] The RTK single-pole centering device provided by the utility model is provided with an extension rod 3 between the centering rod 1 and the integrated pointed head 5, and a second circular level 4 is provided on the extension rod 3. In this way, when measuring points above the ground, the surveyor can level the centering rod 1 through the newly added second circular level 4 at the bottom of the device, thereby achieving accurate measurement. The utility model solves the problem that the existing RTK centering rod cannot ensure whether the centering rod 1 is vertical when measuring higher points, thereby causing large errors in measurement. The device provided by the utility model has a simple principle and strong operability; it has a low production cost and can be assembled by purchasing components, and the required components are available on the market.

[0041] The above are only a few embodiments of the present application and do not constitute any form of limitation to the present application. Although the present application is disclosed as above with preferred embodiments, it is not intended to limit the present application. Any technician familiar with the profession, without departing from the scope of the technical solution of the present application, using the technical content disclosed above to make slight changes or modifications are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
