Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping instruments, in particular to a lifting and lowering surveying and mapping instrument with a stable distance measuring function. Background Art

[0002] In existing surveying and mapping technologies, the stability and flexibility of surveying and mapping instruments are crucial. However, traditional surveying and mapping instruments often have some problems, especially in complex and changing terrain and environments. These instruments may be difficult to place stably or not flexible enough when the height and direction need to be adjusted. These problems may lead to inaccurate surveying and mapping results, which in turn affects the quality of the project.

[0003] Specifically, traditional surveying instruments usually lack an effective lifting mechanism, which requires the use of other equipment or manual adjustment when surveying at different heights, which is not only inefficient but also may affect the accuracy of surveying. At the same time, the leg structure of these instruments is often designed to be relatively simple and cannot provide stable support on different terrains, especially on uneven or slippery ground, where the stability of the instrument is even more difficult to guarantee. In view of this, we propose a lifting surveying instrument with a stable ranging function. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a lifting surveying instrument with a stable distance measuring function.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A lifting surveying instrument with a stable distance measurement function comprises a base 1, a lifting seat 2 is arranged above the base 1, a first screw rod 11 is rotatably installed at the center of the top of the base 1, the first screw rod 11 is threadedly connected to the lifting seat 2, a mounting seat 3 is fixedly installed on the top of the lifting seat 2, a turntable 30 is rotatably installed on the top of the mounting seat 3, a surveying instrument body 31 is installed on the turntable 30, two guide rods 10 are symmetrically fixedly connected to the top of the base 1 and are both plugged into the lifting seat 2, three leg structures 4 distributed in a circular array are installed at the bottom of the base 1, the leg structures 4 include an outer rod 43 and an inner rod 40 that can be telescoped in the outer rod 43, and a first motor 12 whose output shaft is coaxially fixed with the first screw rod 11 is installed at the bottom of the base 1. The first motor 12 on the base 1 drives the first screw rod 11, so that the lifting seat 2 threadedly connected to the first screw rod 11 can stably move up and down, thereby adjusting the height of the surveying instrument body 31. At the same time, the guide rod 10 on the base 1 ensures the stable movement of the lifting seat 2. In addition, the leg structure 4 under the base 1 can be extended and retracted, further enhancing the stability of the surveying instrument. This design not only provides a flexible lifting function, but also ensures the stable placement of the surveying instrument in various terrains.

[0025] As a preferred embodiment of the present invention, a hinge shaft is fixedly connected to the inner rod 40 near the top, and a first side plate 41 is rotatably mounted on both ends of the hinge shaft, and the top of the first side plate 41 is fixedly connected to the bottom of the base 1, and a second motor 42 whose output shaft is coaxially fixed to the hinge shaft is mounted on one of the first side plates 41. By arranging the hinge shaft and the first side plate 41 on the inner rod 40, and driving the hinge shaft by the second motor 42, the automatic deployment and folding of the leg structure 4 can be realized, thereby improving the convenience and automation of the device.

[0026] As a preferred embodiment of the present invention, a mounting groove 44 for the inner rod 40 to move up and down is provided in the outer rod 43, a fixing plate 46 is fixed near the bottom of the mounting groove 44, a second screw rod 45 threadedly connected to the inner rod 40 is rotatably installed on the top of the fixing plate 46, and a third motor 47 whose output shaft is coaxially fixed with the second screw rod 45 is installed at the bottom of the fixing plate 46. The mounting groove 44, the fixing plate 46, the second screw rod 45 and the third motor 47 are provided in the outer rod 43, so that the inner rod 40 can stably move up and down in the outer rod 43, further enhancing the telescopic function and stability of the leg structure 4.

[0027] As a preferred embodiment of the present invention, a rotating shaft 48 is rotatably mounted at the bottom center of the outer rod 43, and a bottom plate 410 is hingedly mounted at the bottom of the rotating shaft 48. By arranging the rotating shaft 48 and the bottom plate 410 at the bottom of the outer rod 43, the leg structure 4 can adapt to uneven ground, thereby improving the adaptability and stability of the surveying instrument under different terrains.

[0028] As a preferred embodiment of the present invention, two second side plates 49 are symmetrically fixedly connected to the top of the bottom plate 410, and the rotating shaft 48 is hingedly installed between the two second side plates 49 through a hinge shaft. The arrangement of the second side plates 49 enables the rotating shaft 48 to be stably hinged to the bottom plate 410, thereby enhancing the stability of the entire leg structure 4.

[0029] As a preferred embodiment of this embodiment, a plurality of evenly distributed anti-skid bumps 411 are fixedly connected to the bottom of the bottom plate 410. The anti-skid bumps 411 at the bottom of the bottom plate 410 can increase the friction with the ground, prevent the surveying instrument from sliding on uneven or slippery ground, and further improve the stability of the device.

[0030] As a preferred embodiment of the present invention, the outer ring wall of the inner rod 40 is closely fitted with the inner wall of the mounting groove 44. The closely fitting design of the outer ring wall of the inner rod 40 and the inner wall of the mounting groove 44 can ensure the stability and accuracy of the inner rod 40 during the up and down movement.

[0031] As a preferred embodiment of the present invention, when the inner rod 40 is fully extended from the mounting slot 44, it is not separated from the second screw rod 45. When the inner rod 40 is fully extended from the mounting slot 44, it is still connected to the second screw rod 45. This design ensures that the inner rod 40 can still maintain a stable supporting force at the maximum extension length, thereby improving the safety and reliability of the device.

[0032] When the lifting surveying instrument with stable distance measurement function of the utility model is used, first, the user can place the surveying instrument at the target location as needed. The leg structure 4 at the bottom of the base 1 can adapt to different terrains through the extension and contraction of the inner rod 40 and the rotation of the outer rod 43 to ensure the stable placement of the surveying instrument. The anti-skid protrusion 411 at the bottom of the bottom plate 410 increases the friction with the ground, further enhancing the stability of the equipment.

[0033] When the user needs to adjust the height of the surveying instrument, the user can drive the first screw rod 11 to rotate by controlling the first motor 12 at the bottom of the base 1. Since the first screw rod 11 is threadedly connected to the lifting seat 2, the rotation of the first screw rod 11 drives the lifting seat 2 to move up and down. At the same time, the guide rod 10 on the base 1 ensures the stability and accuracy of the lifting seat 2 during the movement.

[0034] After the lifting base 2 is moved to a suitable height, the user can adjust the direction of the surveying instrument body 31 through the turntable 30 on the top of the mounting base 3 to perform accurate surveying and mapping.

[0035] In addition, the inner rod 40 of the leg structure 4 can move up and down in the mounting slot 44 in the outer rod 43, so as to adjust the length of the leg. This is achieved by driving the second screw rod 45 to rotate by the third motor 47 on the fixing plate 46. When the leg length needs to be adjusted, the third motor 47 drives the second screw rod 45 to rotate, and since the second screw rod 45 is threadedly connected to the inner rod 40, the inner rod 40 moves up and down accordingly.

[0036] At the same time, the design of the hinge shaft at the top of the inner rod 40 and the first side plate 41 enables the leg structure 4 to be automatically unfolded and folded. When the user needs to unfold or fold the legs, the hinge shaft can be driven to rotate by controlling the second motor 42 on one of the first side plates 41, thereby realizing the automatic unfolding or folding of the legs.

[0037] In general, the lifting surveying instrument of the utility model realizes the stable movement of the lifting seat 2 and the automatic extension and retraction of the leg structure 4 by the rotation of the motor-driven screw rod, thereby providing users with a flexible and stable surveying and mapping platform. This design not only improves the adaptability and convenience of the surveying and mapping instrument, but also ensures the accuracy and reliability of the surveying and mapping work.
