Abstract

The invention provides a mobile loading device for track disease identification. The mobile loading device comprises a loading mechanism, a sensor, a controller, a power supply, a power driving deviceand a chassis, wherein the loading mechanism is provided with a loading motor and a loading force hammer and loads excitation to a rail, a force sensing head is arranged at the end portion of the loading force hammer and is used for feeding back force hammer loading data to the controller, the sensor is in circuit connection with the controller and obtains response information fed back by the excited rail, and the chassis is used for bearing the loading mechanism, the sensor, the controller, the power supply and the power driving device, and is provided with walking wheels in driving connection with the power driving device. The mobile loading device provided by the invention can overcome the instability caused by artificial experience and personal operation habit influence in the prior art, the external illumination condition and dirt on the surface of the to-be-detected structure cannot influence the judgment of the detection result, some hidden diseases which cannot be found by a visual detection method can be detected, hidden dangers can be found as soon as possible, and existing structural safety problems are eliminated in time.

Description

technical field [0001] The invention relates to the technical field of track detection devices, in particular to a mobile loading device for track defect identification. Background technique [0002] With the rapid development of China's rail transit, the operating mileage of high-speed railways and urban rail transit is also increasing, and under the reciprocating action of train loads, various diseases have gradually appeared in the track structure. Therefore, in the rapid development of rail transit At the same time, the demand for line maintenance and track inspection continues to increase, and the integrity of the track structure is also the key to achieving safe and stable train operation. [0003] Most of the existing track detection methods are on-site manual inspection and detection methods based on laser technology and image processing technology. For the on-site worker inspection method, this method relies more on the worker's operating experience, and the detect...
