A floating spiral walking distance measuring device

Abstract

The invention discloses a floating spiral traveling distance measuring device, comprising a device body and two traveling mechanisms respectively installed on the front and rear ends of the device body through end caps. The central axis, the rotating support seat, the sliding support seat, the first spring, the second spring, the pressing member and the 3 sets of floating centering mechanisms, the rotating support seat, the first spring, the sliding support seat and the second spring are nested in the center in turn On the shaft, the rotating support seat and the central shaft are connected by bearings, the first spring, the sliding support seat and the second spring are pressed on the end face of the rotating support seat one by one through the pressing parts, and each group of floating centering mechanism is connected with the rotating support seat and the rotating support seat. The sliding bracket bases are all connected. The advantage is that the use of the principle of spiral motion makes the entire device more stable in startup, acceleration and deceleration and always maintains self-centering. The independent travel wheel measures the displacement without being disturbed by the walking track of the walking wheel. , the measurement accuracy is high.

Description

technical field [0001] The invention relates to the technical field of horizontal landslide displacement measuring equipment, in particular to a floating spiral travel distance meter. Background technique [0002] The horizontal pipeline displacement measurement is generally carried out by means of a trip wheel with a Hall sensor, and the displacement data of the trip wheel is converted into electricity for detection by indirect application of the Hall sensor, so as to realize the pipeline length measurement. [0003] The invention with the application publication number CN107894239A discloses an elastically supported righting log device for an implicit locimeter, which includes a shaft seat connected with an inertial measurement system and a righting log mechanism, and the righting log mechanism includes an elastic member, a sliding shaft and several supporting mechanisms engaged with the sliding shaft, a cavity is opened inside the shaft seat, the elastic member and the sl...

Problems solved by technology

[0004] The above-mentioned odometer device is a fixed straight-forward travel mechanism, and the odometer roller has the functions of odometer and walking at the same time. However, during the walking process, the start and acceleration of the device body are unstable, and it does not have self-centering ability, which is very prone to accidents. Rotating, the walking path of the meter roller will also change accordingly, thereby reducing the accuracy of the meter
