Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pickup technology, and specifically relates to a pickup for railway maintenance. Background Technology
[0002] Railway maintenance is a general term for the periodic maintenance of railway lines and structures, including the maintenance of track, roadbed and other line facilities. In order to maintain track stability and safety, it is necessary to regularly remove stones from the railway, and a stone picker is needed to remove stones.
[0003] Currently, Chinese utility model patent CN222878606U discloses a garbage collector. Although this collector can rotate and align two clamping plates by moving the lower pressure plate upwards, it still has other problems during use. For example, the collection effect is poor, and it cannot effectively fix the collected items. When the collected items are heavy, the friction force of the lower pressure plate moving upwards by the spring contraction is not enough to effectively prevent them from falling off. This can easily cause the collected items to fall during the upward movement, which may injure the user's feet, resulting in poor safety. Moreover, it does not have a length adjustment function, and the distance between the user's holding end and the clamping end is not adjustable. Since the collector is a shared tool, there will be differences when it is used by people of different heights, which reduces the comfort of the operator and reduces flexibility.
