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

Embodiment Construction
[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0022] see Figure 1-Figure 2 As shown, the present invention provides a decelerator on-line monitoring system, including a decelerator 2 installed on the rail 1, which includes a sliding oil cylinder body assembly and a housing assembly, and its structure is the prior art, which is a technology in the art It is well known to the personnel and will not be repeated here. The deceleration top 2 and the rail 1 are fixed by hex nuts and stud bolts, and the spring p...

The invention discloses an on-line monitoring system for a deceleration top, which comprises a deceleration top installed on a rail, an acoustic emission sensor for collecting its acoustic emission source is arranged on the deceleration top, and the acoustic emission sensor is connected to an acoustic emission detector through a transmission line , and a preamplifier is installed on the transmission line between the acoustic emission sensor and the acoustic emission detector. The beneficial effect is that: through online monitoring of the running state of the deceleration jack, after real-time analysis of the monitoring signal, it is determined whether the deceleration jack has performed work, thereby helping the staff to find and replace the faulty deceleration jack in time, thereby eliminating hidden dangers of accidents, and ensuring the safety of railway transportation production.
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...
