Automatic display device for bolt loosening of railway fasteners

Abstract

Disclosed is an automatic display device of a loosening railway fastener bolt, comprising an upper and a lower layer spacer, wherein a light-reflecting device or a light-emitting device (10) is provided on an upper plane of the lower layer spacer (3), the upper layer spacer (4) and the lower layer spacer (3) are connected via a spring (5), a lower plane of the upper layer spacer (4) is adjacent to the upper plane of the lower layer spacer (3), and the upper layer spacer (4) fully covers the light-reflecting device (10) of the lower layer spacer (3). When the fastener bolt loosens to a certain extent, i.e. when the friction between the upper layer spacer and the lower layer spacer is less than the tension of the spring, the overlapped part of the upper layer spacer and the lower layer spacer is separated under the action of the spring tension to expose the light-reflecting device or the light-emitting device such that problems can be easily discovered by a detection device, detection personnel or a train driver, thereby realizing the goal of fast discovery by detection personnel and a detection device.

Description

technical field [0001] The invention relates to an automatic display device for bolt looseness, in particular to an automatic display device for bolt looseness of railway fasteners. Background technique [0002] Since Britain built the first railway in 1825, railway transportation has developed rapidly in countries all over the world. Since my country built the Songhu Railway in 1876, especially after the founding of New China, railway construction has developed rapidly. [0003] In terms of railway safety, railway fasteners are an important part of ensuring railway safety. There has been no fast and accurate way to detect whether railway fasteners are fastened. How to check for taps. The labor intensity of the detection workers is high, the efficiency is very low, and it is easy to miss detection. Although some countries use high-definition camera technology combined with computers, they can only detect whether the fasteners are missing, and cannot detect when the fastene...

The labor intensity of the detection workers is high, the efficiency is very low, and it is easy to miss detection

Although some countries use high-definition camera technology combined with computers, they can only detect whether the fasteners are missing or not when the fasteners are just loose.

[0004] my country is a big country with railways, and the railway transportation is busy. Now my country's inspection of railway fasteners, in addition to manual inspection, also uses the method of loosening and re-tightening the entire railway fasteners after the railway has been used for a certain period of time. Not only the workload is heavy, but also the service life of fastener bolts is shortened due to repeated loosening and fastening
