Problems solved by technology

In order to ensure the smooth operation of inspection and monitoring tasks, it is necessary to strictly control the pre-track installation process. During the track installation process, there will be angle deviations in three-dimensional space, and the common method of manual measurement with an inclinometer can only obtain the two-dimensional angle of the track. The above deviation, and the measurement error is large, the process is cumbersome, there are safety hazards when manually climbing to measure, and the efficiency is low

Embodiment Construction

[0025] The walking mechanism of the present invention can adopt the robot walking mechanism provided by the invention patent with the application number of 201610186221.1. The walking mechanism uses a high-performance brushed motor as power, and there is a positioning system under the driving wheel, combined with the motor encoder The position ring can be accurate The walking distance is collected. The walking mechanism has eight guide wheels. At both ends of the walking mechanism and the track, there are four guide wheels. Turn a certain angle on the horizontal plane to adapt to the steering adjustment, which can realize steering without dead angle, and no force in the direction of motion will be generated at the turning. A positioning system is installed on the walking mechanism, and 9 magnetic steels are used to cooperate with the Hall sensor to achieve non-contact. When the track does not need to be installed with power supply, the walking distance of the positioning mechan...

Abstract

The invention provides a track flatness measuring method. The method includes the following steps of (1) placing a walking mechanism with an acceleration sensor, an angular velocity sensor, a magnetic sensor on a track, and moving the walking mechanism to the corresponding position; (2) acquiring the original data of the acceleration sensor and the angular velocity sensor, and obtaining the pitch angle, the yaw angle and the roll angle of the walking mechanism according to the original data; and (3) determining whether the pitch angle, yaw angle, and roll angle obtained in step (2) within the standard threshold interval, and if the angles are in the standard threshold interval, the track is flat, if not, the track is not flat. The track flatness measuring method can intelligently determine the flatness of the track installation and realize the simplicity, safety and efficiency of the operation of the track installation and detection.

Description

technical field [0001] The invention relates to a method for measuring the flatness of a track. Background technique [0002] The daily inspection and monitoring tasks of rail robots are carried out on the rails, so the robots have high requirements for the stability and flatness of the rails. In order to ensure the smooth operation of inspection and monitoring tasks, it is necessary to strictly control the pre-track installation process. During the track installation process, there will be angle deviations in three-dimensional space, and the common method of manual measurement with an inclinometer can only obtain the two-dimensional angle of the track. On the deviation, and the measurement error is large, the process is cumbersome, there are safety hazards when manually climbing to measure, and the efficiency is low. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides a method for measuring the flatn...
