Method and device for automatically checking fastening states of railway fasteners and spring fasteners

Abstract

The invention relates to a method and a device for automatically checking fastening states of railway fasteners and spring fasteners. The method includes steps of acquiring positioning data of the railway fasteners, acquiring fastening state judgment data of the spring fasteners, combining the positioning data of the railway fasteners and the fastening state judgment data of the spring fasteners to complete checking the fastening states of the railway fasteners and the spring fasteners. The device comprises a railway bogie, a linear structure laser sensor, a photoelectric coder, a GPS (global positioning system) receiver, a synchronous control circuit, an embedded computer and a power source device, wherein the linear structure laser sensor, the photoelectric coder, the GPS receiver, the synchronous control circuit, the embedded computer and the power source device are arranged on the railway bogie. The method and the device for automatically checking the fastening states of the railway fasteners and the spring fasteners have the advantages that accurate positioning of the railway fasteners can be realized, completeness in checking of the railway fasteners and the spring fasteners is realized, the fastening states of the railway fasteners and the spring fasteners can be automatically checked, detail information of the railway fasteners can be recorded, and alarm for the fastening states of the railway fasteners and the spring fasteners is realized.

Description

Technical field [0001] The invention belongs to the field of instrument science and technology, and relates to a method and corresponding equipment for inspecting the fastening state of railway spring bar fasteners, and in particular to a railway spring bar fastener fastening based on multi-sensor integration technology and laser micrometer technology. Method and device for automatic inspection of solid state. Background technique [0002] The track fastener system is a key component of the track structure, which is mainly composed of bolts, nuts, flat washers, spring bars, insulating blocks, iron backing plates, insulating cushion plates, under-rail backing plates, anchor bolts, heavy spring washers, and flat washers And other composition. The failure of fasteners is mainly manifested as missing fasteners, broken spring bars, loose fastening bolts, and elastic failure of spring bars. The basic functions of the track fastener system include: maintaining the gauge, preventing th...
