Description

Technical Field

[0001] The invention relates to the field of railway maintenance machinery and vehicles, and in particular to a track-moving amount detection device for a bridge and tunnel cleaning machine. Background Art

[0002] When the bridge and tunnel cleaning machine is operating on a curve of a bridge or tunnel, the width of the bridge or tunnel ballast bed is narrower than the main line, and the end of the sleeper on the outside of the curve is too close to the side wall of the ballast bed, causing the excavation device to collide with the side wall of the ballast bed. Therefore, when performing bridge and tunnel cleaning operations, the main track lifting and shifting device can be used first to perform track lifting and shifting operations, and the track row can be shifted a certain distance to the inside of the curve to ensure a safe distance between the end of the sleeper and the side wall of the ballast bed. After excavation and cleaning, the auxiliary track lifting and shifting device can be used to restore the track row to the corresponding position before the operation. In this process, the lifting height and lateral displacement of the main track lifting and shifting device and the auxiliary track lifting and shifting device need to be measured in real time to provide real-time data for the operation, so as to ensure that the line is smooth and controllable after the clean ballast backfilling of the bridge and tunnel cleaning operation.

[0003] The lifting beam of the main track lifting and shifting device only undergoes vertical and lateral displacements relative to the vehicle frame, so two pull-wire sensors can be installed to measure the amount of track lifting and track shifting required for its operation. However, the movement of the lifting beam of the auxiliary track lifting and shifting device relative to the vehicle body is more complicated, and the entire mechanism undergoes combined movements in the four directions of up, down, left and right. If a single pull-wire sensor is added, the pull wire will inevitably be pulled obliquely. Therefore, the traditional sensor arrangement method cannot accurately calculate the amount of track lifting and shifting of the auxiliary track lifting and shifting device.

[0004] In view of the defects existing in the existing technology, the purpose of the present invention is to provide a track lifting and shifting amount detection device for a bridge and tunnel cleaning machine, which can accurately detect the track lifting and shifting amount of the auxiliary track lifting and shifting device, ensure the safe distance between the pillow end and the ballast retaining side wall when the bridge and tunnel cleaning machine is operating and the smoothness of the line after the operation, and effectively improve the operating safety and quality of the bridge and tunnel cleaning machine.

The angle value detected by the absolute value single-turn encoder 3 and the pull-out value of the wire sensor 2 can be used to calculate the real-time track lifting and shifting amount of the auxiliary track lifting and shifting device 7 through the geometric trigonometric relationship.
