Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of track maintenance, in particular to a maintenance device for track transportation. Background Art
[0002] Track maintenance is a variety of track maintenance operations carried out to ensure that the track is in good condition and that trains can run safely, smoothly and uninterruptedly at the specified speed. It includes track renewal and repair to restore the performance of various track components, and regular maintenance work to prevent and eliminate deformation and damage to the track caused by train power and other influences. In order to ensure driving safety and the good condition of various track components, extend the service life of various track components, and avoid economic losses caused by long-term disrepair of track equipment, it is necessary to investigate, study, formulate and implement a maintenance system to ensure that the track is in good condition. Most of the existing technologies are to dismantle the track section by section and then repair it. This is not only troublesome but also inefficient because the most vulnerable damage to the track is deformation and disease caused by train power and other influences. If the entire track is dismantled for repair of such damage, it will result in extremely high costs.
[0003] At the same time, the patent specification with announcement number CN 217997686 U discloses a track maintenance auxiliary device, including a track and an installation box, a sliding rod fixedly installed between the two opposite inner walls of the installation box, an elastic component slidably connected to the sliding rod, two receiving rods fixedly installed at the bottom of the elastic component, the bottoms of the two receiving rods are respectively connected to the two sides of the track, the top of the elastic component is hinged with a connecting plate, and two hinges are fixedly installed at the bottom of the connecting plate.
[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned track maintenance auxiliary device has the following problems: when the device is used to repair the track, the entire track needs to be dismantled and then repaired. This not only wastes more time and energy, but it is also rare for the track to need to be dismantled for repair. Most of the time, the track is corrected and repaired by grinding and repairing the deformation caused by external forces. However, the repair of deformation can still be carried out without dismantling the rails.
[0005] Therefore, in order to solve the above problems, a maintenance device for rail transportation is proposed. Utility Model Content

The fixed sleeve 9 is fixedly connected to the protective cover 6, so the fixed gear 10 fixedly connected to the fixed sleeve 9 also remains stationary, and the rotating shaft 12 drives the rotating gear 11 to rotate while rotating. The rotating gear 11 drives the rotating shaft 12 and the grinder 13 to rotate while rotating. The grinder 13 grinds the surface of the track body 5 at the same time during the rotation and rotation. In order to prevent the iron chips produced by the grinding from flying around, special holes are set on both sides.
