Abstract

The invention provides a leveling device. The leveling device comprises a supporting part, at least two adjustable supporting parts, at least two horizontal sensing parts, a feedback module and at least two locking structures. The supporting part is provided with a first end suitable for being fixedly connected with a foundation and a second end rotatably connected with a plane to be adjusted; each adjustable supporting part is provided with a first connecting end suitable for being fixedly connected with the foundation and a second connecting end rotatably connected with the plane to be adjusted, and at least two second connecting ends are not collinear with the connecting points of the second end and the plane to be adjusted; the at least two horizontal sensing parts are used for continuously measuring the inclination angle of the plane to be adjusted; the feedback module receives the inclination angle numerical values, and when the inclination angle numerical values are equal to set angles, control signals are sent out; the at least two locking structures are electrically connected with the feedback module, after the control signals are received, the adjustable supporting parts are locked, and the adjustable supporting parts become rigid supporting parts. According to the leveling device, after the adjustable supporting parts are pressed, the adjustable supporting parts can be automatically bounced to be opened, other drive structures do not need to be used, and the device is simple in structure, low in cost and high in adjusting efficiency.

Description

technical field

[0001] The invention relates to the technical field of leveling devices, in particular to a leveling device. Background technique

[0002] In some occasions, it is necessary to use some high-precision measuring equipment, and these measuring equipment often need to be deployed on a horizontal base to operate normally. These equipment include various angle measuring, distance measuring, height measuring, mapping and orientation instruments used in engineering construction. The more common ones are level, theodolite, total station, etc. Various equipment such as optical tables, wind tunnel models, etc. In the prior art, the commonly used solution is to use a tripod. People manually adjust the three legs of the tripod to obtain a relatively flat plane. However, this adjustment method is not only cumbersome, time-consuming and laborious, but also the flatness of the obtained plane is not high. .
