[0002] Under the background of the increasingly development of modern rail transit system (including railway, urban rail transit etc.), the cleaning and maintenance of track is very important for the safety and efficient operation of the whole traffic system. With the continuous increase of rail transit line and the accumulation of operation time, various sundries will inevitably accumulate on the track. These sundries are not conducive to the safety of rail transit, so cleaning is needed.

[0003] At present, the existing track cleaning mechanism has poor versatility. Because the tracks used by different regions and different types of rail transit have diversity in track gauge (such as standard gauge, narrow gauge, etc.) and specifications (including differences in size, shape and material of steel rail), the existing cleaning mechanism is often designed and manufactured for specific track gauge and specifications, which leads to the fact that the existing track cleaning mechanism is difficult to adapt to the needs of tracks with different track gauges and specifications in actual application, and is inconvenient to use.

[0004] Therefore, the present application provides a track cleaning structure to solve the above technical problems. UTILITY MODEL CONTENTS

[0035] Specifically, the cleaning seat 3 has a fastening bolt 301 at its end. The fastening bolt 301 is inserted into the cleaning seat 3 and abuts against the outer edge of the outer cleaning block 5 to form a fixation. The roller 4 has threads, and the inner cleaning ring 401 is screwed onto the roller 4. Therefore, the insertion depth of the outer cleaning block 5 can be adjusted by loosening or loosening the fastening bolt 301, so that the distance between the outer cleaning block 5 and the inner cleaning ring 401 can be adapted to different specifications of track rails.

[0036] The working principle of the utility model provides, the track cleaning structure, when using, can connect mobile equipment through pull rod 101, can control two sliders 201 mirror image activity through rotating drive rod 102, drive two extension plates 2 to carry out telescoping at the both ends of base 1, make the device adapt to the track of different track pitch.

[0037] Meanwhile, the insertion depth of the outer cleaning block 5 on the cleaning seat 3 can be adjusted, the outer cleaning block 5 is fastened by the fastening bolt 301, and the inner cleaning ring 401 installed on the roller 4 is matched, so that the inner cleaning ring 401 and the outer cleaning block 5 can collectively clean the inner side, the outer side and the upper surface of the normal rail of different specifications.

[0038] In summary, the device can not only adapt to tracks of different track pitches, but also adapt to normal rails of different specifications, so that the track surface debris can be cleaned and scraped, and the use is flexible.

[0039] The utility model covers any alternative, modification, equivalent method and scheme made on the essence and range of the utility model. In order to make the public have the thorough understanding of the utility model, the specific details are explained in the following preferred embodiment of the utility model, and the utility model can also be completely understood without the description of these details for the person skilled in the art. In addition, in order to avoid unnecessary confusion to the essence of the utility model, well-known methods, processes, procedures, elements and circuits are not explained in detail.
