Device for detecting dowty retarder

Abstract

The invention discloses a device for detecting dowty retarders. The device consists of a trolley, a trolley body, a servo motor, a pneumatic pump, a dowty retarder detecting device, following wheels,driving wheels and an inclination angle sensor, wherein the trolley carries the dowty retarder detecting device to detect the dowty retarders on the two sides of a track, the electromagnetic inductionprinciple is adopted to detect whether the dowty retarders can be retracted normally or not, and detecting accuracy is improved. The faulted dowty retarders are numbered, the positions of the faulteddowty retarders are located, the positions and the numbers of the faulted dowty retarders are sent to the corresponding maintenance department through a GPRS module, workers are reminded to go to repair the faulted dowty retarders, the pneumatic pump is adopted to input high-pressure gas into the dowty retarder detecting device, and whether a sliding oil cylinder can be retracted or not is detected. The performance of the dowty retarders can be recognized without artificial foot stepping, the labor cost is effectively reduced, and the skeletal injury caused by artificial foot stepping on thedowty retarders is reduced.

Description

technical field [0001] The invention relates to the field of performance detection of deceleration tops, in particular to a device for detection of deceleration tops. Background technique [0002] The deceleration jack is used in the hump speed control system of the railway marshalling station. It is a hydraulic device that decelerates the running vehicle through the sliding cylinder cap. It is a kind of hydraulic equipment that does not require external energy and external control, and can control the speed of the rolling vehicle more accurately. device of. [0003] The retarder is an independent hydraulic unit with hydraulic oil and nitrogen as the working medium. It is exposed to the open air all the year round, and it is prone to leakage of hydraulic oil and gas, parts aging, damage, fatigue, etc. These losses make the retarder malfunction. The probability increases. The failure or damage of the deceleration jack will affect the normal operation of the marshalling yard...

[0003] The retarder is an independent hydraulic unit with hydraulic oil and nitrogen as the working medium. It is exposed to the open air all the year round, and it is prone to leakage of hydraulic oil and gas, parts aging, damage, fatigue, etc. These losses make the retarder malfunction. Increased probability

The failure or damage of the deceleration jack will affect the normal operation of the marshalling station, and in severe cases, it will cause vehicle collisions and derailment accidents, threatening the safe production of the railway

[0004] In the prior art, the quality of the decelerator is mainly checked by the maintenance personnel by stepping on it, and the quality of the decelerator is judged according to the usual experience, but it is affected by factors such as each person's height, weight, experience, etc. , there is a large difference in the fault judgment of the retarder, which cannot be scientific and accurate, which greatly affects the maintenance of the retarder, resulting in a reduction in the braking capacity and service life of the retarder.

At the same time, most maintenance personnel are used to stepping on the deceleration roof with their right feet, which will have a certain impact on human legs and feet in the long run.
