Problems solved by technology
[0003] Using the above-mentioned method to repair the retarders has the following problems: 1. Due to the large number of retarders installed in the marshalling yard and the huge range, maintenance personnel will spend a lot of time and energy on all the retarders in the marshalling yard; 2. , The method of detecting the retarder fault mainly relies on manual inspection, and judges whether the retarder is damaged or leaked by visually inspecting the external structure. The braking performance of the retarder can only be determined by stepping on it one by one. Judgment, the detection error is large, and the inspection is prone to failure; in many marshalling yards, although some deceleration tops have not yet been repaired, the braking function is significantly reduced, and the critical speed changes, which is prone to overspeeding and damage to the vehicle The accident has become a hidden danger to the shunting operation and personal safety in the marshalling yard

The invention discloses an online monitoring system for a retarder. The online monitoring system for the retarder comprises the retarder installed on a rail, wherein an acoustic emission sensor acquiring an acoustic emission source of the retarder is arranged on the retarder; and the acoustic emission sensor is connected with an acoustic emission detector through a transmission line, and a pre-amplifier is installed on the transmission line between the acoustic emission sensor and the acoustic emission detector. The online monitoring system for the retarder has the following beneficial effects: online monitoring is carried out on a running state of the retarder, and whether the retarder applies work or not is determined after real-time analysis on a monitoring signal, so that working personnel are helped to find and replace a failed retarder in time, and then potential accidents are eliminated, and the railway transportation and production safety is ensured.
Description
technical field [0001] The invention relates to the technical field of railway deceleration jack control, in particular to an online decelerator monitoring system. . Background technique [0002] The speed reducer is a hydraulic speed regulating device used in the hump speed control system of the railway marshalling station. The speed reducer speed control system is a continuous speed control system composed of multiple speed reducers. If a single retarder in the retarder speed regulation system fails, it will affect the overall speed regulation effect of the system. Therefore, the maintenance and repair of retarders has become an important task in marshalling yards. The existing retarder maintenance work adopts the combination of manual inspection, outdoor maintenance and indoor overhaul. [0003] Using the above-mentioned method to repair the retarders has the following problems: 1. Due to the large number of retarders installed in the marshalling yard and the huge rang...
