Gravitational potential energy impact type acceleration generating device

Abstract

The invention belongs to the technical field of railway security detection, and relates to a gravitational potential energy impact type acceleration generating device. The gravitational potential energy impact type acceleration generating device is especially used for judging whether a clamp of an acceleration sensor on a seamless high-speed railway is correctly installed or not and judging whether the acceleration sensor arranged on the seamless high-speed railway works normally or not. The gravitational potential energy impact type acceleration generating device consists of an acceleration generating device body and a high intensity magnetic lead attraction mechanism. The acceleration generating device body is provided with a gantry-type loading platform, the lower end of an aluminum tube is connected and installed on the top of the gantry-type loading platform through threads, a metal ball is attracted by a magnetic base and placed at the upper end of the aluminum tube, and a control switch is installed on the side face of the magnetic base. A thin cotton rope 1 is tied on a powerful magnetic lead 2, and the high intensity magnetic lead attraction mechanism is formed. The gravitational potential energy impact type acceleration generating device has the advantages of being convenient to operate, simple in structure, portable, easy to carry, stable and reliable in performance, high in efficiency, good in field maneuverability and free of destroying the installation of an original acceleration sensor clamp in the field.

Description

Technical field [0001] The invention belongs to the technical field of railway safety detection, and relates to a gravitational potential energy impact acceleration generator, and is particularly aimed at judging whether the acceleration sensor fixture on the seamless high-speed railway is installed correctly and whether the acceleration sensor installed on the seamless high-speed railway is working normal. Background technique [0002] After several years of rapid development, my country has become the country with the longest operating mileage, the highest operating speed, and the largest scale of high-speed railways in the world. The maintenance and monitoring of high-speed railways has become an issue that must be faced. Rail is the most basic safety component in high-speed railways. Due to the long-term high-speed operation of high-speed trains, the rails are subject to great impact. The rails are prone to damages such as peeling, corrugated surfaces, and cracks. At the same...

Problems solved by technology

For judging whether the acceleration sensor is working normally, the commonly used method in the research process is to remove the wireless sensor network node and the acceleration sensor fixture together to replace the new wireless sensor network node and the acceleration sensor fixture or to remove and replace part of them, or to replace the two complete sets of equipment. Part of the exchange is used to compare and troubleshoot faults. This method has a large workload, and the experiment period is long, and the experiment cost is very high; it is impossible to judge whether the acceleration sensor fixture is installed after installation.
