Intelligent fastener

Abstract

The invention discloses an intelligent fastener. The intelligent fastener comprises a hook, a tension sensor, a communication module, a screw and a hook lock element. The tension sensor is set below the hook. The communication module is set below the tension sensor. The communication module is a circuit board. A CPU, a battery, an antenna and an indicator lamp are set on the circuit board. The tension sensor is connected with the CPU. The battery is connected with the CPU and the tension sensor. The antenna is connected with the CPU. The indicator lamp is connected with the CPU. The indicatorlamp is used for carrying out flicker alarm when tension collected by the tension sensor is greater than a set threshold. The screw is set at the lower end of the communication module. The hook lock element is set on the screw. According to the intelligent fastener, all-directional, real-time and intelligent monitoring can be carried out on the fastener at a background.

Description

technical field [0001] The invention relates to the field of vehicle slip prevention, in particular to an intelligent fastener. Background technique [0002] Since the beginning of the 21st century, with the rapid development of railway traffic in the direction of high efficiency, convenience and safety, higher requirements have been put forward for the safety of the working environment of railway traffic. The most important link, the traditional fastener is the main anti-slip method. At present, the staff can only rely on the on-site inspection to determine whether the vehicle is in the anti-slip state. However, the original Ministry of Railways TB / T 3095-2004 document stipulates that : The axial tension generated by the fastener on the manual brake should be 10-14.7KN. Since it involves the tension of a specific value range, it is difficult for the inspectors to determine whether the tension value of the fastener is up to standard, and the intermediate station stops When ...

Since it involves the tension of a specific value range, it is difficult for the inspectors to determine whether the tension value of the fastener meets the standard, and the intermediate station stops When there are too many vehicles or are affected by bad weather, it is difficult to achieve all-round and real-time monitoring of the fastening status of the fasteners only by relying on staff inspections
