Description

Technical Field

[0001] The utility model relates to the technical field of tracks, in particular to a CN turnout center rail elastic roller replacement device. Background Art

[0002] The CN turnout elastic roller is a key component in the railway turnout system. It has unique elasticity and rotation performance, and plays a vital role in ensuring the smooth operation of trains at the turnout and reducing friction resistance.

[0003] In daily maintenance, the rotation and wear of the rollers and the tightening of the fixing screws should be checked regularly to ensure that they are in good working condition. When the elastic roller is used for a certain period or is worn and deformed to a certain extent, it needs to be replaced. At present, the elastic replacement operation of CN turnout mainly uses a special hydraulic press to manually squeeze out the old roller in the elastic roller locking iron, and then squeeze the new roller to the correct position. This method is not only time-consuming and labor-intensive, but also greatly affected by the environment. For example, the spacing between the elastic roller locking iron and the basic rail is too small, or the spacing between the fasteners of the engineering and the external lock is too small, which will make it impossible for the hydraulic press to be placed in the normal position, making it difficult to remove the elastic roller. Only by removing other components can the hydraulic press be placed in the normal position to replace the roller. This operation is not only a huge workload, but also has a great impact on the normal operation of the equipment. Therefore, it is very important to design a roller extractor that is simple to operate, easy to carry, and less affected by the on-site environment for the maintenance of railway turnouts.
