Land planning levelness measuring device with self-balancing structure

Abstract

The invention relates to the technical field of surveying and mapping, in particular to a land planning levelness measuring device with a self-balancing structure. The device comprises a self-balancing rack mechanism, two groups of vertical frame mechanisms and a measuring mechanism, the self-balancing rack mechanism is symmetrically provided with the two groups of vertical frame mechanisms, and the two ends of the measuring mechanism are fixedly connected with the two groups of vertical frame mechanisms respectively. The electric push rod is controlled to operate through the first laser transmitter and the two sets of photosensitive sensors, the function of adjusting the height of each corner of the U-shaped rack is achieved, self-balancing of the U-shaped rack is achieved, manual calibration is not needed, the accuracy of the levelness measurement result is optimized, and measurement is conducted through multiple lasers at the same time. If the laser coincidence phenomenon occurs, it is indicated that the measuring device is in a fault state, it is convenient for workers to check device faults, the upper gear is manually shifted to drive the anti-dazzling screen to rotate, three-gear adjustment of laser brightness is achieved, the measuring requirements under different light rays are met, and the practicability of the device is better.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to a levelness measuring device for land planning with a self-balancing structure. Background technique [0002] Level measurement is a measurement method that uses a measuring device to measure a certain plane to determine whether the plane is on a horizontal line. It is essentially a measurement process of position error. A measuring device is required for level measurement. Existing Most of the current level measurement devices are laser-type measurement devices, which emit laser light through laser emitting equipment to calibrate the plane. However, the existing level measurement devices need to ensure that the device is in a horizontal state during use, and the installation surface of the device is usually The ground cannot guarantee that the installation surface is in a horizontal state, so it is necessary to manually adjust the device frame during use. The manua...
