AI Technical Summary

Technical Problem

The start-up and shutdown of existing nodal seismographs rely on manual operation one by one, which is inefficient. Furthermore, the existing automation solutions are only applicable to static arrangement scenarios and cannot be integrated with automated field operations. During transportation, the instrument's positional accuracy is difficult to guarantee, resulting in the magnetic control switch and magnetic column not being accurately aligned.

Method used

The system employs a double-layer conveyor rail structure, combined with a conical centering boss and a correction inclined block design, to achieve automatic conveying and precise positioning of the nodal seismograph. It enables batch start-stop via a magnetically controlled start-stop mechanism and utilizes electric and hydraulic telescopic rods for precise centering and buffering vibration reduction, preventing debris from entering.

Benefits of technology

The system enables automated batch start-up and shutdown of nodal seismographs, improving operational efficiency, ensuring the positional accuracy of the instruments during transport and the precise alignment of the magnetic control switches, protecting internal components, preventing foreign objects from entering, and reducing the risk of impact damage.

Abstract

This invention relates to the field of nodal seismograph technology and discloses a nodal seismograph start-stop device, comprising a start-stop equipment body and a nodal seismograph body. The start-stop equipment body has a conveying mechanism inside, which includes: a conveying guide rail mounted on the start-stop equipment body, comprising an upper guide rail and a lower guide rail arranged parallel and spaced apart, and a driving component mounted on the conveying guide rail; and multiple bearing grooves, all disposed on the conveying guide rail, the bearing grooves being divided into upper and lower grooves, the upper grooves being fixedly disposed on the upper guide rail, and the lower grooves being fixedly disposed on the lower guide rail, the upper and lower grooves being staggered, and the bearing surface of each bearing groove being a downwardly concave arc shape. Under the action of the conveying mechanism, this nodal seismograph start-stop device can not only realize the continuous automated conveying of nodal seismographs and the synchronous batch start-stop of upper and lower layers, but also form a vibration reduction system through arc-shaped line contact.
