[0002] In the field of surveying, portable surveying instruments are widely used due to their portability and flexibility. Surveying rigs, as crucial auxiliary equipment, play a key role in measurement accuracy and work efficiency. Traditional surveying rigs often rely on manual leveling, requiring surveyors to spend considerable time and effort on repeated calibrations. This cumbersome operation is susceptible to human error, leading to low measurement efficiency. Regarding steering adjustment, some rigs lack flexibility, making it difficult to quickly and accurately adjust the surveying instrument's angle, thus limiting the measurement range. Height adjustment functions also have limitations, failing to adapt well to complex and diverse terrain environments. Furthermore, traditional rigs occupy a significant amount of space when stored, hindering their carrying and transportation during fieldwork. With increasingly complex surveying scenarios and ever-increasing demands for measurement accuracy and efficiency, the development of a portable surveying rig for surveying instruments that features automatic leveling, convenient steering and height adjustment, and easy storage and carrying has become an urgent need to meet modern surveying requirements and promote the development of surveying technology.

[0031] Reference Figure 1-10 A surveying support for a portable surveying instrument includes a circular box 1, a circular plate 2, and a rotating ring 34. The circular plate 2 is positioned above the circular box 1, and an annular groove is formed on the bottom side of the circular plate 2. The rotating ring 34 is rotatably mounted in the annular groove. Three circular blocks 3 are rotatably mounted on the top of the circular box 1. An electric cylinder 31 is radially fixedly mounted on each of the three circular blocks 3. The working ends of the three electric cylinders 31 are hinged to hinge seats 32. The three hinge seats 32 are fixedly mounted with the same retaining ring 33, and the retaining ring 33 is fixedly mounted on the bottom side of the rotating ring 34 and is connected to the circular box 1. The bottom side of plate 2 is movable, which can adjust the level of the circular plate 2 as needed, while preventing debris and dust from entering the annular groove, thus avoiding affecting the normal rotation of the rotating ring 34. A level sensor 38 is fixedly installed on the bottom side of the circular plate 2, and the level sensor 38 is electrically connected to three electric cylinders 31 through the controller. It can monitor the level status of the circular plate 2 in real time when the device is turned on, and can control the three electric cylinders 31 to quickly adjust the level of the circular plate 2 when the circular plate 2 is not level.

[0032] The top side of the rotating ring 34 is provided with a mounting groove, which is arranged in a ring shape. A gear plate 37 is fixedly installed on the inner wall of the top side of the ring groove, and a servo motor 35 is fixedly installed on the inner wall of the mounting groove. A drive gear 36 that meshes with the gear plate 37 is fixedly sleeved on the output shaft of the servo motor 35. It can control the circular plate 2 to perform steering operation as needed, thereby achieving the effect of controlling the surveying instrument installed on the circular plate 2 to perform steering.

[0033] Three mounting bases 41 are fixedly installed at the bottom of the circular box 1. Each of the three mounting bases 41 is hinged with a telescopic rod 4. Each of the three telescopic rods 4 is hinged with a pad 42 at the end away from the mounting base 41. The pad 42 is L-shaped, which facilitates the support of the circular box 1 and other components when it is unfolded, and also facilitates the adjustment of the support height. It can also provide support for the device when it is folded up. Three fixing blocks 431 are fixedly installed at the bottom of the circular box 1. Each of the three fixing blocks 431 is fixedly installed with a limit pin 43. Each of the three pads 42 has multiple through holes. The three limit pins 43 are respectively inserted into the corresponding holes, which can effectively limit the telescopic rods 4 when they are folded up. A spirit level 21 is fixedly installed on the top side of the circular plate 2, which makes it easy for the operator to observe the level of the circular plate 2.

[0034] In this embodiment, in order to ensure that the telescopic rod 4 provides a limiting effect after adjustment and to prevent the telescopic rod 4 from deflecting on its own based on the mounting base 41, a rubber pad 401 is fixedly attached to one end of the telescopic rod 4 near the mounting base 41, and the rubber pad 401 is in contact with the mounting base 41.

[0035] In this embodiment, in order to provide a preliminary limiting effect for the telescopic rod 4 after it is stored, three clamping plates 402 are fixedly installed at the bottom of the circular box 1, and the three telescopic rods 4 are respectively clamped and installed in the corresponding clamping plates 402.

[0036] In this embodiment, in order to provide the electrical energy required for the device to work and to facilitate disassembly and replacement, an arc-shaped opening is provided on the side wall of the circular box 1, and a battery compartment 11 is snapped into the arc-shaped opening.

[0037] In this embodiment, in order to facilitate carrying the device, two U-shaped handles 22 are hinged to the top side of the circular plate 2.

[0038] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0039] Working principle: In use, first connect the power supply, unfold the three telescopic rods 4 around the corresponding mounting bases 41, and provide support through the pads 42. Alternatively, the pads 42 can be stably fixed to the ground using external anchors or through holes. The support height can be changed by adjusting the length of the telescopic rods 4. The rubber pads 401 can increase friction after adjustment to prevent the telescopic rods 4 from deflecting around the mounting bases 41. When storing, insert the telescopic rods 4 into the locking plate 402 for initial positioning, and then insert the limiting pins 43 into the through holes of the pads 42 for further fixation. The handle 22 facilitates carrying by the operator, while the battery compartment 11 provides power to the device and facilitates disassembly and reassembly. After powering on, the level sensor 38 monitors the level of the circular plate 2 in real time. If the circular plate 2 is not level, the level sensor 38 transmits a signal to the controller. The controller controls the three electric cylinders 31 to work. The electric cylinders 31 push the retaining ring 33 through the hinge seat 32. Through the coordinated extension and retraction of the three electric cylinders 31, the circular plate 2 is adjusted to be level. This allows the retaining ring 33 and the circular plate 2 to be quickly adjusted to a level state, so that the surveying instrument mounted on the circular plate can quickly enter a level state. At the same time, the operator can directly observe the level of the circular plate 2 through the bubble level 21, which in turn drives the rotating ring 34 to rotate in the annular groove on the bottom side of the circular plate 2.

[0040] When it is necessary to control the direction of the surveying instrument, the servo motor 35 starts, and the drive gear 36 on its output shaft meshes with the gear plate 37 to drive the circular plate 2 to rotate on the rotating ring 34, thereby causing the circular plate 2 and the surveying instrument mounted on it to rotate, thus enabling the surveying instrument to adjust its direction.

[0041] The above provides a detailed description of a portable surveying instrument support provided by this utility model. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
