Floating spiral walking mileage metering device

Abstract

The invention discloses a floating spiral walking mileage metering device, which comprises a device body and two traveling mechanisms respectively mounted at the front and rear ends of the device body through end caps. The device body includes an instrument bin and a mileage metering bin. The traveling mechanisms include central shafts, rotating bracket seats, sliding bracket seats, first springs, second springs, pressing members, and three sets of floating centering mechanisms; the rotating bracket seats, the first springs, the sliding bracket seats, and the second springs are nested on the central shafts successively; the rotating bracket seats and the central shafts are connected by bearings; the first springs, the sliding bracket seats, and the second springs are compressed on the end surfaces of the rotating bracket seats one by one by compressing members; and each set of floating centering mechanisms is connected with the sliding bracket seat and the rotating bracket seat. The device has the following advantages: on the basis of the principle of spiral motion, the whole device is started, accelerated, or decelerated stably and the self-centering is kept all the time; displacement measurement is performed by using an independent meter wheel to avoid the walking track interference of the wheel, so that the measurement accuracy is high.

Description

technical field [0001] The invention relates to the technical field of horizontal landslide displacement measurement equipment, in particular to a floating spiral travel log device. Background technique [0002] Horizontal pipeline displacement measurement is generally carried out by means of a taxi wheel with a Hall sensor, and the displacement data of the taxi wheel is converted into electricity for detection through the indirect application of the Hall sensor, thereby realizing the measurement of the pipeline length. [0003] The invention with the application publication number CN107894239A discloses a rectifying trip meter device with elastic support for an implicit tracker, which includes a shaft seat connected to an inertial measurement system and a righting trip log mechanism. The righting trip log mechanism includes elastic parts, sliding shafts and several support mechanisms engaged with the sliding shaft, a cavity is opened inside the shaft seat, the elastic membe...

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
