Description

Technical Field

[0001] The utility model relates to the field of railway maintenance, in particular to a real-time detection device for track cracks. Background Art

[0002] Railway tracks are referred to as rails for short, and are used to support the movement of trains along the direction in which the tracks are laid. Railway tracks are usually composed of two parallel steel rails, which are fixed on sleepers. The rails are I-shaped structures, and the upper end surface of the upper wing plate contacts and bears pressure with the rail wheel in the train. Under long-term extrusion and friction, they are always in a polished state; the side of the web plate in the rail and the vertical side of the upper wing plate do not contact the rail wheel, and cannot be extruded and polished. During long-term use, they are prone to rust, affecting the structural strength and stability of the rails. At the same time, there may be garbage and debris on both sides of the rails or on the rails, which may be rolled into the bottom of the train and affect the normal operation of the train.

[0003] When crack detection is performed on a rail, dust or other impurities adhere to the inner side of the rail, which may cause a large data acquisition error in the image acquisition device, making the crack on the inner side of the rail difficult to be photographed and discovered.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A real-time detection device for rail cracks, comprising a rail body 1 and a detection device 2, wherein a plurality of monitors 10 are arranged on both sides of the rail body 1, a plurality of bottom wheels 12 that can move on the rail body 1 are arranged at the bottom end of the rail body 1, a plurality of positioning plates 3 are arranged at the four corners of the detection device 2, two side plates 4 are symmetrically arranged on one side of the positioning plate 3, a motor 5 is fixedly arranged at the upper end of the side plate 4, a rotating shaft 11 that passes through the side plate 4 is arranged at the output end of the motor 5, a rotating block 6 is fixedly arranged at the bottom end of the rotating shaft 11, and a plurality of bristles that contact the rail body 1 are arranged on the peripheral side of the rotating block 6;

[0024] In this structure, the bottom wheel 12 can be an electric wheel, which can drive the detection device 2 to move on the track body 1. The number of monitors 10 is not mandatory here. As the detection device 2 moves, the monitor 10 can transmit the captured images to the designated monitoring device, and the staff can monitor it in real time.

[0025] During the movement of the detection equipment 2, multiple motors 5 will be started synchronously. At this time, the rotating shaft 11 will drive the rotating block 6 to rotate.
